Description

Technical Field

[0001] The utility model relates to the technical field of axle head processing tooling fixtures, in particular to axle head processing tooling fixtures with good stability. Background Art

[0002] The hub of the automobile is an important safety part of the automobile. Its structure is divided into two categories: with flange and without flange. The structure with flange generally adopts round flange, and its processing technology is simple, but some customers require the use of special-shaped flange structure, which makes the processing and fixing difficult and greatly increases the processing difficulty.

[0003] The existing shaft head fixture generally clamps the outside of the shaft head. Due to the large number of customer demands, the shaft heads have different shapes, which makes the fixture not very compatible with the shaft head, resulting in some shaft heads not being clamped stably enough. The existing shaft head fixture is fixed with screws, which is troublesome, time-consuming and laborious to disassemble. Therefore, in order to solve the above problems, a shaft head processing fixture with good stability is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a shaft head processing fixture with good stability to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A shaft head processing tooling fixture with good stability comprises a fixing rod, the bottom end of the fixing rod is fixedly connected to a universal joint, the bottom end of the universal joint is fixedly connected to a fixing shell, a first limit groove is provided on one side of the fixing shell, a second limit groove is provided inside the fixing shell, a connecting rod is slidably connected inside the second limit groove, a third limit groove is provided inside the connecting rod, a fixing pin is snap-connected inside the first limit groove and the third limit groove, the outer side of the connecting rod is slidably connected to the shaft head, the outer side of the connecting rod is slidably connected to a flange located at the bottom end of the shaft head, a shaft neck is provided on the outer side of the shaft head, and the bottom end of the connecting rod is fixedly connected to a fixing plate.

[0007] Preferably, the bottom end of the fixed shell is fixedly connected to a first rubber layer, the bottom end of the first rubber layer is fixedly connected to a first rubber bump, the top end of the fixed plate is fixedly connected to a second rubber layer located outside the connecting rod, and the top end of the second rubber layer is fixedly connected to a second rubber bump.

[0008] Preferably, the number of the first rubber protrusions is several and they are evenly arranged on the surface of the first rubber layer.

[0009] Preferably, the number of the second rubber protrusions is several and they are evenly arranged on the surface of the second rubber layer.

[0010] Preferably, the diameters of the first limiting groove and the third limiting groove are consistent and both are larger than the diameter of the fixing pin.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, by setting the fixing shell, the second limiting groove, the connecting rod and the fixing plate and other components, the connecting rod is inserted from the bottom end of the flange into the inside of the flange and the shaft head. No matter the external shapes are different, the inside can only remain circular. The shaft head, the flange and the shaft neck are fixed by the connecting rod and the fixing plate, thereby solving the problem that the existing shaft head fixture generally clamps and engages the outside of the shaft head. Due to the large number of customer demands, the shaft heads have different shapes, making the fixture unable to be well compatible with the shaft head, resulting in the problem that the clamping of some shaft heads is not stable enough;

[0013] 2. In the utility model, by setting the connecting rod, the first limiting groove, the third limiting groove, the fixing pin and the second limiting groove and other components, after the connecting rod is inserted into the flange and the shaft head, the connecting rod higher than the shaft head part is inserted into the second limiting groove inside the fixed shell, so that the first limiting groove and the third limiting groove are aligned, and then the fixing pin is inserted into the first limiting groove and the third limiting groove, so as to prevent the connecting rod and the fixed plate from falling off, and quickly complete the fixing of the shaft head, the shaft neck and the flange, without the need to use screws to slowly tighten, thereby solving the problem that the existing shaft head fixture is fixed by screws, which is troublesome to disassemble, time-consuming and labor-intensive;

[0014] 3. In the utility model, by providing the first rubber layer, the first rubber convex points, the second rubber layer and the second rubber convex points and other components, the top end of the shaft head can be clamped by the first rubber layer and the first rubber convex points, and the bottom end of the flange can be clamped by the second rubber layer and the second rubber convex points. By clamping the upper and lower parts simultaneously, the friction between the fixed shell and the fixed plate and the shaft head and the flange can be greatly improved, effectively preventing the shaft head and the flange from rotating, and further improving the stability of the fixed structure.
