Description

Technical Field

[0001] This utility model relates to the field of shock absorber manufacturing technology, and in particular to a positioning device for a shock absorber flanging and sealing machine. Background Technology

[0002] like Figures 1-2 As shown, currently, during the production of shock absorbers 11, in order to seal the cylinder 111 of the shock absorber 11, a flanging sealing machine is needed to flanging the sealing lip 112 at the top of the cylinder 111 inward for sealing. Existing flanging sealing machines generally use a positioning device to drive the shock absorber 11 to rotate, and then the rollers of the flanging sealing machine press and flanged the sealing lip 112 to achieve the sealing effect. However, some shock absorbers 11 have a cylindrical bottom end, such as... Figure 1 As shown, the shock absorber 11 includes, from bottom to top, a cylindrical section 113 with a smooth outer wall, a limiting section 114 with an increased outer diameter, and a clamping section 115 with a polygonal cross-section. When the positioning device rotates, relative sliding easily occurs between the positioning device and the cylindrical section 113, which causes the shock absorber 11 to be unable to rotate. Therefore, there are still shortcomings and deficiencies in the prior art. Utility Model Content

[0003] This utility model provides a positioning device for a shock absorber flanging and sealing machine to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a positioning device for a shock absorber flanging and sealing machine, including a mounting base, a positioning hole on the mounting base, an openable clamping mechanism above the mounting base, a support rod between the clamping mechanism and the mounting base, the lower part of the support rod being fixedly connected to the mounting base, and the top part of the support rod being connected to the clamping mechanism.

[0005] Preferably, a fixing ring is fixedly connected to the clamping mechanism, and the fixing ring is slidably sleeved on the top of the support rod.

[0006] Preferably, a receiving groove is coaxially formed on the top surface of the mounting base, and a positioning ring is detachably connected inside the receiving groove, with positioning holes formed on the positioning ring.

[0007] Preferably, a relief cavity is provided on the inner bottom surface of the receiving groove, and the inner diameter of the relief cavity is smaller than the inner diameter of the receiving groove.

[0008] Preferably, the clamping mechanism includes a self-locking clamp, and the inside of the clamping jaws of the self-locking clamp has a clamping groove.

[0009] Preferably, a hexagonal connecting groove is provided on the bottom surface of the mounting base, and a connecting through hole is provided at the bottom end of the mounting base through the connecting groove.

[0010] The beneficial effects of this utility model are as follows: (1) By setting a clamping mechanism to clamp the clamping section of the shock absorber, this utility model can prevent relative sliding between the shock absorber and the positioning device, thereby driving the shock absorber to rotate; (2) Since the fixing ring is slidably sleeved on the support rod, it is convenient to replace the clamping mechanism of different specifications so as to match the shock absorber of different sizes, thereby improving the applicability of the device; (3) Since the positioning ring and the receiving groove are detachably connected and the positioning hole is opened on the positioning ring, it is convenient to replace the positioning hole of different specifications so as to match the shock absorber of different sizes, thereby further improving the applicability of the device.

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] like Figure 1-7As shown, this utility model provides a positioning device for a shock absorber flanging and sealing machine, including a mounting base 1, a positioning hole 2 on the mounting base 1, the positioning hole 2 being adapted to the cylindrical section 113 of the shock absorber 11, an openable clamping mechanism 3 on the upper part of the mounting base 1, the clamping mechanism 3 being used to clamp the clamping section 115 of the shock absorber 11, a support rod 4 being provided between the clamping mechanism 3 and the mounting base 1, the lower part of the support rod 4 being fixedly connected to the mounting base 1, and the top part of the support rod 4 being connected to the clamping mechanism 3, when the mounting base 1 rotates, the mounting base 1 can drive the clamping mechanism 3 to rotate through the support rod 4.

[0021] Specifically, the positioning device needs to be used in conjunction with the flanging and sealing machine. When in use, the mounting base 1 is connected to the positioning shaft of the flanging and sealing machine. Then, the clamping mechanism 3 is opened, and the cylindrical section 113 of the shock absorber 11 is inserted into the positioning hole 2. The positioning hole 2 can fix the shock absorber 11 and close the clamping mechanism 3 to clamp the clamping section 115. Then, the mounting base 1 is driven to rotate through the positioning shaft. The mounting base 1 drives the clamping mechanism 3 to rotate through the support rod 4. Since the clamping mechanism 3 can clamp the clamping section 115 of the shock absorber 11, it can prevent relative sliding between the shock absorber 11 and the positioning device, thereby driving the shock absorber 11 to rotate. Finally, the flanging and sealing operation of the shock absorber 11 can be performed by the flanging and sealing machine.

[0022] In some embodiments, a retaining ring 5 is fixedly connected to the clamping mechanism 3, and the retaining ring 5 is slidably sleeved on the top end of the support rod 4. Specifically, when the mounting base 1 rotates, the mounting base 1 can drive the clamping mechanism 3 to rotate through the support rod 4 and the retaining ring 5. In addition, since the retaining ring 5 is slidably sleeved on the support rod 4, it is convenient to replace clamping mechanisms 3 of different specifications to match shock absorbers 11 of different sizes, thereby improving the applicability of the device.

[0023] In some embodiments, a receiving groove 6 is coaxially formed on the top surface of the mounting base 1, and a positioning ring 7 is detachably connected to the receiving groove 6. A positioning hole 2 is formed on the positioning ring 7. Specifically, since the positioning ring 7 is detachably connected to the receiving groove 6, and the positioning hole 2 is formed on the positioning ring 7, it is convenient to replace positioning holes 2 of different specifications to match shock absorbers 11 of different sizes, thereby further improving the applicability of the device.

[0024] In some embodiments, a relief cavity 8 is provided on the inner bottom surface of the receiving groove 6, and the inner diameter of the relief cavity 8 is smaller than the inner diameter of the receiving groove 6. Specifically, the relief cavity 8 can accommodate the bottom end of the shock absorber 11. Since the inner diameter of the relief cavity 8 is smaller than the inner diameter of the receiving groove 6, a limiting structure can be formed at the connection between the relief cavity 8 and the receiving groove 6, and the limiting structure can support the positioning ring 7.

[0025] In some embodiments, the clamping mechanism 3 includes a self-locking clamp 31. The inner side of the jaws of the self-locking clamp 31 is provided with a clamping groove 32. The clamping groove 32 is adapted to the clamping section 115 of the shock absorber 11. In this way, the clamping groove 32 can fit the clamping section 115 of the shock absorber 11, thereby enabling the self-locking clamp 31 to clamp the clamping section 115 of the shock absorber 11.

[0026] In some embodiments, a hexagonal connecting groove 9 is provided on the bottom surface of the mounting base 1, and a connecting through hole 10 is provided at the bottom end of the mounting base 1, penetrating the connecting groove 9. Specifically, the positioning shaft of the flanging and sealing machine is provided with a connecting protrusion that matches the connecting groove 9, and the connecting block is provided with a fixing through hole corresponding to the connecting through hole 10. By providing the connecting groove 9 and the connecting through hole 10, the mounting base 1 can be easily connected to the positioning shaft for transmission.

[0027] The above embodiments can be combined with each other.

[0028] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
