Description

The invention relates to general engineering and can be used for positioning equipment.

A device for positioning equipment is known, comprising a block of three parts, on adjacent surfaces of which guide grooves for the support rollers are made, while the direction of the grooves for the support rollers of the first and second parts is perpendicular to the direction of the grooves of the second and third parts, the mechanisms of mutual shift of the block parts made in the form of screw pairs, each of which is located between the block parts in each pair, on adjacent surfaces of the block parts of each pair, on both sides of the grooves for support rollers, parallel to them, grooves and protrusions are made that are engaged by the “dovetail” type, all parts of the block have holes in which a jack is placed, fixed by its body on the first part of the block, the holes of the second and third parts are sized, providing free movement relative to them of the cargo screw of the jack during mutual shift of the parts of the block (see Patent RU 2283271, published September 10, 2006).

This device allows the equipment to be positioned along three axes (X, Y, Z), and horizontal positioning along the X, Y axes is carried out by screw pairs located between the first and second parts and between the second and third parts in a rectangular (Cartesian) coordinate system .

In the known device, positioning in the horizontal plane is carried out in mutually perpendicular rectilinear directions along the X and Y axes, and these movements are carried out sequentially first along one axis, then along the other, while the center of the support spherical tip of the cargo screw occurs along a broken line, which imposes a limitation to use the device in some cases, for example, when it is necessary to dock the equipment flange with its counterflange, having centri uyuschie belts and arranged relative to each other originally skewed.

The technical result of the invention is the elimination of this drawback of the known device, namely: ensuring the displacement of the center of the support spherical tip of the cargo screw to any point within the projected working space, ensuring the accuracy of adjusting the angular position of the equipment to the joined object along an arc of a circle, ensuring the accuracy of joining of the equipment flange with it mating flange having centering bands and located relative to each other initially with a bias.

The technical result of the invention is achieved due to the fact that the device for positioning the equipment contains a block of three parts located one above the other, on adjacent surfaces of which are made guide grooves for supporting rollers enclosed in the separator, mechanisms for mutual displacement of the respective adjacent parts of the block, on adjacent surfaces of the first and second block parts are made of straight guides parallel to the guide grooves for the support rollers of the first and second parts of the block, all parts of the block have holes in which the jack is placed, fixed by its body on the first part of the block, the holes of the second and third parts are sized to allow free movement of the jack screw relative to them during mutual shift of the block parts, while the guide grooves for the support rollers of the second and third parts of the block made circular, the mechanism of mutual shift of the second and third parts of the block is made in the form of a gear pair formed by a gear rim made on the second part of the block, and a gear or worm, a mustache anovlennym the third part of the block to transmit torque to the second portion of the block.

The third part of the block can be made in the form of a cylindrical pedestal with a flange at its lower end having an annular groove on the outer cylindrical surface, and the second part of the block can have a cylindrical protrusion freely covering the cylindrical surface of the third part of the block.

In the cylindrical protrusion of the second part of the block, holes are made in which the latches are installed in the form of restrictive screws included in the annular groove of the third part.

The ring gear is made mainly on the outer surface of the cylindrical protrusion of the second part of the block.

The mechanism of mutual shift of the first and second parts of the block is made in the form of two screw pairs, the screws of which are coaxial, lean with their heads on the protrusions of the first part of the block and are screwed into the threaded holes of the protrusions of the second part of the block.

The cargo screw of the jack at the upper end has a supporting spherical tip, and the lower threaded part is screwed into the threaded hole of its housing.

The device for positioning the equipment comprises a block of three mutually movable parts 1, 2, 3 located one below the other, on adjacent surfaces of which guide grooves 4, 5 are made for the support rollers 6, 7. Guide grooves 4 for the support rollers 6 on adjacent surfaces of the parts Blocks 1 and 2 are made rectilinear, parallel to each other and symmetrical with respect to the centers of the blocks 1, 2. The guide grooves 5 for the support rollers 7 on the adjacent surfaces of the parts 2 and 3 of the block are made circular, while their centers coincide with the centers of the parts 2 and 3 of the block (central holes). The support rollers 6 located in the guide grooves 4 are predominantly cylindrical, and the support rollers 7 located in the guide grooves 5 are conical. Also, instead of cylindrical and conical rollers, other motion transmission elements, for example spherical, can be used.

On the adjacent surfaces of the block parts 1 and 2 parallel to the guide grooves 4 on their outer side, straight guides are made in the form of grooves 8 and projections 9 on the corresponding parts 1, 2 of the block, which are engaged in a dovetail type (Fig. 8) .

Part 3 of the block is made in the form of a hollow cylindrical pedestal having a flange 10 on one end (bottom), and an annular groove 11 on the outer cylindrical surface near the other (upper) end 11. Part 2 of the block has projections 12 (Fig. 6) directed to side of the first part 1 of the block, and a cylindrical protrusion 13 (flanging) (Fig. 4, 5), directed towards the flange 10 of part 3, freely covering the cylindrical surface of part 3 of the block with the possibility of movement (rotation relative to the third part 3). Part 1 of the block is made in the form of a plate, on the sides of which are perpendicular to the grooves 8 and protrusions 9 (rectilinear guides), protrusions 14 (Fig. 6) are directed towards the side of the block 2.

The device contains mechanisms for the mutual shift of the respective adjacent parts 1, 2, 3 of the block. In this case, the mechanism of mutual shift of parts 1 and 2 of the block is made in the form of two screw pairs (Figs. 2, 3), the screws 15 of which are coaxial and rely with their heads 16 on the protrusions 14 of part 1 of the block and are screwed into the holes 17 of the protrusions 12 of part 2 of the block ( 6). The mutual shift mechanism of parts 2 and 3 of the block is made in the form of a gear pair formed by a ring gear 18 made on the outer surface of the cylindrical protrusion 13 of the block part 2 and a gear 19 (Fig. 8) or a worm 20 (Fig. 9) mounted on the flange 10 of part 3 of the unit with the possibility of transmitting torque to part 2 of the unit.

All parts 1, 2, 3 of the block have central openings in which a jack is mounted, fixed with its housing 21 on part 1 of the block, while the cargo screw 22 of the jack is screwed with the lower threaded part into the threaded hole of its housing 21. Part 1 of the block has a central hole with a diameter corresponding to the outer diameter D of the housing 21 of the jack (figure 1). The hole of the block part 2 has a size L, which allows the free movement of the jack screw 22 of the jack when the respective parts of the block are mutually offset, the size L being at least the sum of the outer diameter of the jack screw 22 and twice the maximum displacement of the corresponding block parts.

The cargo screw 22 of the jack at the upper end has a supporting spherical tip 23 and a protrusion (hexagon) 24 for installing the tool (key).

Each row of support rollers 6, 7 is enclosed in separators 25, 26 (Fig. 3, 7). In the cylindrical protrusion 13 of part 2 of the block, threaded holes 27 are made, located at the same level with the annular groove 11 of the third part, in which the latches 28 are installed in the form of restrictive screws, which, with their heads 29, enter the annular groove 11 in order to fix part 3 relative to part 2 of the block (figure 4).

The gear 19 is mounted movably on the vertical axis 30 (Fig. 5) of the flange 10 of part 3 with the possibility of transmitting torque to the ring gear 18 by means of a removable lever 31, which engages with the gear 32 socket 19. If parts 2 and 3 blocks of the worm pair, the worm 20 is mounted movably on the protrusions 33 of the flange 10 of part 3 of the block (Fig. 9).

The device operates as follows.

The device is designed for limited movement of equipment in three dimensions (horizontal and vertical). The movements in the horizontal plane are provided by the mutual shift of the block parts 1 and 2 in the radial direction and the mutual shift of the parts 2 and 3 in the tangential direction, i.e. in the polar coordinate system (by changing the radius R and angle α) (Fig. 8).

The sequence in the work of the device is as follows.

1. All parts of the device are restored to their original position, i.e. the centers of the parts 1, 2, 3 of the unit are aligned, and the cargo screw 22 of the jack is in its lowest position.

2. The device is installed under a specially made socket on the equipment 34 (Fig.1, 2) in the form of a blind hole. A tool is installed in the hexagon 24 of the cargo screw 22, for example, a wrench, with which the cargo screw 22 is unscrewed from the jack housing 21, comes into contact with the equipment socket 34 and raises it to the required height above the support.

3. Screws 15 (Fig.6) offset part 1 of the block relative to part 2 of the block. For example, you want to move the upper part 1 relative to part 2 to the right (figure 2). For this, the screw 15, located to the right of the cargo screw 22, is unscrewed, and the screw 15 on the left side of the screw 22 is screwed using the tool socket 35 (Fig. 6). In this case, the screw 15 is screwed into the threaded hole 17 of the protrusion 12 of the block part 2, with its head (shoulder) 16 pushes the block part 1 to the right (Fig. 6) by the required value, after which this position is fixed with the screw 15 located to the right of the jack screw 22, screwing it all the way into the right ledge 12 of part 2 of the block.

4. Regulation of the device in the tangential direction is carried out by a mutual shift of parts 2 and 3 of the block by means of a gear pair formed by a gear ring 18 on the protrusion 13 of part 2 of the block and gear 19 mounted movably on the vertical axis 30 (Fig. 5). The movement of the block part 2 by the required angle α (Fig. 8) relative to the part 3 of the block is carried out by a removable lever 31, the tip of which 36 is engaged with the socket 32 of the gear 19.

The adjustment of the device in the variant embodiment is carried out in the same way, however, the regulation in the tangential direction is carried out by a mutual shift of the block parts 2 and 3 by means of a worm pair formed by a ring gear 18 (Fig. 9) on the protrusion 13 of part 2 and the worm 20 mounted movably on the protrusions 33 of the flange 10 parts 3 blocks. Turning the worm 20 in one direction or another by the handle 37, ensure the rotation of part 2 around the circumference by the required angle α.

Restrictive screws 28 (figure 4) perform the same function as the system of grooves 8 and protrusions 9, ensuring the engagement of parts 2 and 3 of the block with each other, as well as their fixation, if necessary. The fixation is carried out by screwing the screws 28 until the head 29 of the screw 28 is in full contact with the annular groove 11 of the unit 3.

The movement of equipment 34 during regulation is carried out on the support rollers 6 and 7, which perceive the mass of equipment and reduce the friction forces between parts 1, 2, 3 of the block.

The device is simple, easy to operate when positioning equipment.
