The HF130 axle housing is one of the main products of our company. During the reproduction, the HF130 axle housing needs to be clamped and fixed so that processes such as flange holes can be processed on the main body of the axle housing. The existing clamping and fixing method of our company is to use the eccentric sleeve to drive the screw and the nut to clamp the workpiece. However, in actual production, it is found that when the workpiece is clamped by this method, there are problems such as low clamping efficiency and easy damage to the eccentric sleeve.

Utility model content:

The utility model aims to overcome the deficiencies in the prior art and provide a fast push-pull locking device for the axle housing with simple structure, convenient use, firm clamping, and self-locking function.

The utility model provides the following technical solutions:

A fast push-pull locking device for the axle housing, which includes a base, and is characterized in that: a groove is arranged on the base, a through hole is arranged at the bottom of the groove, and the base on one side of the through hole An anti-rotation sleeve is connected to the seat, and a screw sleeve is provided in the anti-rotation sleeve, and a bolt that forms a locking fit with the screw sleeve is also provided on the anti-rotation sleeve, and a screw rod is arranged in the screw sleeve, and one end of the screw rod is connected with A hinged seat for rotation fit is formed, and a pair of claw rods are hinged on the hinged seat. A long groove is provided on each claw rod, and the long grooves are all slidably connected to a fixed seat, and the fixed seat is connected with the inner wall of the groove.

On the basis of above-mentioned technical scheme, also can have following further technical scheme:

A handle is provided at one end of the screw rod, and a ring groove is provided on the shaft body at the other end of the screw rod, and the ring groove is connected with the hinge seat through a screw and forms a rotation fit with it.

An L-shaped groove for matching with the bolt is provided on the surface of the screw sleeve.

An arc-shaped limiting plate of the axle housing is connected to the base at the opening side of the groove.

The utility model has the advantages of:

This utility model is designed by our company in combination with the actual experience in the production of the axle housing, using waste materials, combined with the current production situation, and through continuous test verification. It has simple structure, convenient use, firm clamping, and self-locking function. In addition, the utility model can also ensure the overall stability and normality of the axle housing processing process in actual production, so it can effectively increase production capacity, improve product quality, and reduce the manufacturing cost of the axle housing.

Detailed ways:

As shown in Figure 1, a kind of fast push-pull locking device for axle housing, it comprises base 1, is provided with a groove 1a on base 1, is provided with a through hole 1b in the bottom of groove 1a, An anti-rotation sleeve 2 is connected to the base on the side of the through hole 1b through a connecting piece 1d, and an arc-shaped positioning bar 1c is provided on the base on the opening side of the groove 1a as shown in FIG.

As shown in Figures 2 and 3, a screw sleeve 3 is provided in the anti-rotation sleeve 2, and an L-shaped groove 3a is also provided on the surface of the screw sleeve 3, and the long groove and the short groove are perpendicular to each other, while the long groove The direction is consistent with the axial direction of the screw sleeve 3 , and the groove 3 a can form a locking fit with the locking bolt 2 a on the anti-rotation sleeve 2 .

As shown in Figure 5, only a section of thread is provided in the screw sleeve.

As shown in Figures 2 and 3, the threaded sleeve 3 is provided with a screw 4 matched with it, one end of the screw 4 is provided with a handle 4a, and the other end of the screw 4 is provided with a section of unthreaded polished rod portion. An annular groove 4b is provided along the circumferential direction on the top, and the annular groove 4b is connected with the hinge seat 5 through a screw 5a and forms a rotational fit with it.

A pair of pawl levers 6 is hinged on the hinge seat 5 through a pin shaft 5b, and a long strip-shaped through groove 6a is arranged axially on the body of each pawl lever 6 . As shown in Figures 1 and 2, two fixing seats 7 are correspondingly connected to the inner wall of the groove 1a, and the fixing seats 7 are provided with a pin shaft 7a that forms a sliding fit connection with the long groove 6a.

working principle:

As shown in Figures 1 and 2, first turn the screw sleeve to snap the locking bolt 2a into the short groove in the L-shaped groove, so that the screw sleeve cannot rotate together with the screw rod, and then buckle the inner cavity 8 of the axle housing on the base Then rotate the handle on the screw rod 4 to push the screw rod forward, and then push the hinged seat and the claw rod to protrude forward, and the claw rod will gradually move to both sides due to the restriction of the fixed seat. Stretch out the base, this is the inner cavity 8 of the axle housing that the claw at the end of the claw bar can block.

After the processing of the axle housing is completed, turn the handle on the screw rod 4 in the reverse direction first, so that the claw at the end of the claw rod is separated from the inner cavity of the axle housing. At this time, the screw sleeve will also rotate in reverse with the screw rod, making the bolt 2a slide Go to the knuckle in the L-shaped groove, and then directly pull the screw rod backward. At this time, the bolt 2a will slide along the long groove in the L-shaped groove, and the claw lever can be quickly retracted.
