(54) DEVICE FOR HEIGHT CONTROL

I

The invention relates to a reference measurement technique and can be used to control the dimensional accuracy of parts processed on automatic lines, for example, of a rotary type.

A device is known for controlling a height, for example, a flange in parts with npt points, containing a case, mounted along the axis of symmetry of the case, a receiver of controlled parts, a cup movable in the axial direction, and spring loaded two arms with wasps. mikachani mounted on the glass, rollers mounted on one end of the pivot, base bearings fixed on the other ends of the levers, a rotary cam sleeve interacting with the rollers, a drive lever mounted on the cam bushing, and a linear displacement sensor mounted 6 receivers controlled details ij.

In the known device, pei provides the mechanism for the final submission of parts

to the measuring position, which reduces the productivity of the control and complicates the first design of the device. In addition, the movable base bearings are constantly pressed against the support surface, which leads to their wear.

The aim of the invention is to improve the performance and reliability of the device.

This goal is achieved due to the fact that the device is equipped with a threaded bushing installed in the housing with the possibility of pServrr agitation relative to it, and rigidly connected in a rotary cam bushing and interacting with the article through a thrust bearing.

FIG. 1 device for controlling the flange, flange, flange in parts with npOTOHKBiMB; in fig. 2 is a diagram of the position of the movable base bearings at the time of measurement.

The device includes a housing L. with a sensor 2 linear

702232 displacement, rotary cam sleeve 3, rigidly connected with threaded sleeve 4, screwed into housing 1, and driving lever 5, bowl 6, axially movable, -p & spring loaded levers 7 with 8 swing axles fixed On Stack: 1e 6,. Rabies. 9, mounted on the upper ends of the double-blade levers 7 and constantly in contact with the rotary cam sleeve 3, the basic supports 10 mounted on the lower ends of the double-shouldered levers 7 and positioned in the guide grooves of the support 11 mounted on the support above. of the receiver 12, the controlled part 13, to the ejector 14 of the controlled parts after the control. The device works as follows. . In the initial state of rotation; Kyf Lachk sleeve 3 through rollers 9 turns two shoulders levers 7, thanks to which the basic supports 10 are separated. The controlled part 13 is fed into the receiver 12 and then with the measuring rod of the sensor 2 Linear displacements into the centering hole of the support 1J. Moreover, the groove of the part 13 is mounted with against the base supports 10. When turning the drive lever 5, turn the cam and cam sleeve 3. with the threaded sleeve 4. This leads to the fact that the rollers 9 are released, .4 drilling p1 1 pins 7, under the action of 1 pin, rotates on the swing axle 8 and introduces the backbone of the support 10 into the groove of the part 13. At the same time, the threaded cone 4 is screwed into the casing 1 ia through the fixed yo shi The pnick informs glass 6 pceaois displacement, thus providing axial displacement and supports 10, which interact with the junction surface of part 13, pressing it against the support surface of the receiver 12, ensuring the force closure of the base supports. At this point, the sensor 2 linear displacement is turned on, providing a counter; the role of the height of the flac of the part 13. At the end of the control, the blinker 14 blinks the detail 13 from the control zone. The formula of the invention A device for controlling the height, for example, of a flange in parts with grooves, comprising a housing, mounted along the axis of symmetry of the housing, a receiver of controlled parts, a cup, movable axially, spring loaded two shoulders with axes of swing,; 1 lengthened on the glass, rollers, fixed, Hbie on one end of the levers, basic supports,: fixed, on the other ends of the levers, rotary cam sleeve interacting with the rollers, drive lever fixed on the cam sleeve, and linear sensor transducer An apparatus installed in a receiver of monitored parts, characterized in that, in order to control the production; The device is equipped with a threaded bushing installed in the housing with the possibility of axial movement relative to it, and a rigid hub with a rotary cam bushing and interacting with the hundred through a thrust bearing.
