Detailed Description
The invention will be further described in detail with reference to the following examples:
the axle housing part is leveled by adopting an axle housing part universal automatic leveling device, as shown in figure 2, the device comprises a fixed seat 5, and the bottom of the fixed seat 5 is connected with a lower support 6; the top of the fixed seat 5 is connected with a supporting block 9 through two springs 7 and 8 (namely, a spring I and a spring II) with different specifications, and the two springs 7 and 8 are respectively arranged in two grooves of the fixed seat through a bearing 10;
the leveling method comprises the following steps:
the main hole reducing surface of the axle housing part 15 is placed on the supporting block 9 of the general automatic leveling device of the axle housing part in an upward mode, and the main hole reducing surface of the axle housing part 15 is automatically kept in a horizontal state under the action of the general automatic leveling device of the axle housing part 15.
The bearing 10 is a linear bearing, and the arrangement can ensure that the spring sleeve does not collide with the outside in the downward movement process of the spring sleeve, so that the problem that the spring sleeve cannot move downwards due to collision with the outside is avoided.
The springs 7 and 8 (namely the first spring and the second spring) are respectively sleeved with a spring sleeve 11, and the spring sleeve 11 is sleeved in the bearing 10.
A gap exists between the spring housing 11 and the bearing 10.
There is a clearance between the spring housing 11 and the outer diameters of the springs 7, 8 (i.e., spring one and spring two).
The bottom of the fixed seat 5 is fixedly connected with the lower bracket 6 through a first screw 12.
The bearing 10 is fixedly connected with the fixed seat 5 through a second screw 13.
The spring sleeve 11 is fixedly connected with the supporting block 9 through a third screw 14.
Specifically, the process of leveling the axle housing part by adopting the universal automatic leveling device for the axle housing part provided by the invention comprises the following steps:
(1) when the axle housing part 15 just contacts the supporting block 9, the contact surface of the axle housing part 15 is not completely in a horizontal state (when the included angle between the contact surface and the horizontal state is alpha degrees), and the supporting block 9 can be inclined downwards at one contact side (as shown in fig. 3);
(2) after the supporting block 9 is inclined, firstly, the spring sleeve 11 is inclined at a certain angle, and a gap between the original spring sleeve 11 and the linear bearing 10 is eliminated and is tightly attached to the side edge of the linear bearing 10; then pushing the spring housing 11 to compress the spring (compression amount X) to move downwards along the linear bearing 10;
(3) during the downward movement of the spring housing 11, the contact surface of the supporting block 9 and the axle housing part 15 is flush (as shown in fig. 4);
(4) after the contact surface of the supporting block 9 and the axle housing part 15 is flat, the axle housing part 15 pushes the supporting block 9 to move downwards again until the bearing position of the axle housing part 15 is contacted with the bearing positioning block;
(5) the whole gravity of the axle housing part 15 is supported by the bearing positioning block; however, in the circumferential direction, the axle housing part 15 often has a different structure, so that the problem of center-of-gravity eccentricity can be caused, and the axle housing part rotates circumferentially along the circle center; in this embodiment, to keep the main hole reducing surface 16 of the axle housing part 15 in a horizontal state, two sets of springs (spring one and spring two) with different specifications are selected to overcome the eccentric problem of the center of gravity of the axle housing part, one eccentric side selects a spring with a slightly larger spring force, the other side selects a spring with a slightly smaller spring force, then the spring sleeve 11 contacting the supporting block 9 side first has a large downward movement amount and causes the first and second springs to have different compression amounts, the spring with the large compression amount generates a large compression force, which prevents the axle housing part from rotating around the center of a circle due to the eccentric center of gravity, and the main hole reducing surface 16 of the axle housing part is always in a horizontal state (as shown in fig. 5).
