Description

Technical Field

[0001] The utility model belongs to the technical field of washer production, and particularly relates to a press-fitting fixture for automotive aluminum washers. Background Technique

[0002] Automotive aluminum washers are components used for the installation of automotive wheels. They are usually installed between wheel bolts and wheels, playing roles such as filling gaps, dispersing pressure, and increasing friction. Aluminum washers have advantages such as light weight and corrosion resistance compared to traditional steel washers, and are suitable for improving the performance and appearance of automobiles. Most of the existing washer production uses stamping methods for manufacturing. Aluminum washers are manufactured by punching metal sheets with the punch of a stamping machine. To ensure the production quality of aluminum washers, a fixture is required to clamp and fix the metal sheet during stamping.

[0003] In the prior art, there is a clamping and positioning tooling for washer production stamping with the patent publication number CN216575249U. The above patent includes two pneumatic fixtures and an installation frame. The front ends of the two pneumatic fixtures are fixedly connected to the installation frame. The installation frame includes a fastening plate, a clamping end, a middle pressure hole, a card slot, a first top block, a connecting block, a second top block, and a connecting rod. This device clamps and fixes the clamping end provided on the installation frame through the pneumatic fixture. At the same time, a connecting block is provided on the other side of the installation frame, and the clamping end and the connecting block are fixedly connected through the first top block, the second top block, and the connecting rod, thereby supporting both sides of the installation frame and improving the clamping stability of the pneumatic fixture for the installation frame, and further improving the stability of the metal sheet inside the installation frame. However, there are still the following deficiencies in actual use: In reality, during the stamping production of aluminum washers, the thin plate is fixed on the clamping device. After stamping, the processed workpiece is disassembled and then the next workpiece to be processed is installed. Loading and unloading are carried out separately. In this way, loading and unloading consume the time of two processes, and the processing efficiency is low, which is not conducive to the efficient production of aluminum washers.

[0004] Therefore, a press-fitting fixture for automotive aluminum washers is needed to solve the problem of low processing efficiency caused by separate loading and unloading of aluminum washers in the prior art. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present utility model in conjunction with embodiments.

[0022] Please refer to Figures 1-4, the present utility model provides a pressing fixture for automotive aluminum gaskets, including a workbench 1. Multiple support columns 2 are fixedly connected to the bottom of the workbench 1. A first rotating shaft 3 is rotatably connected to the center position of the top of the workbench 1. A first synchronous pulley 4 is fixedly connected to the outer wall of the first rotating shaft 3. A second rotating shaft 5 is rotatably connected to a position near one side of the top of the workbench 1. A second synchronous pulley 6 is fixedly connected to the top of the second rotating shaft 5. A synchronous belt 7 is installed on the outer walls of the first synchronous pulley 4 and the second synchronous pulley 6. A driving motor 8 corresponding to the second rotating shaft 5 is installed at the bottom of the workbench 1. A frustum 9 is fixedly connected to the top of the first rotating shaft 3. Clamping mechanisms 10 are arranged at positions near the front and rear ends of the top of the frustum 9. An L-shaped support plate 11 is fixedly connected to a position near the rear end of the top of the workbench 1. A stamping die 12 is installed at the front end of the L-shaped support plate 11.

[0023] Further, as shown in Figure 1 , Figure 2 and Figure 3 it is worth specifically stating that shock pads are fixedly connected to the bottoms of the multiple support columns 2, ensuring that the workbench 1 is always in a stable state throughout the production process, and further improving the stability of the stamping work.

[0024] Further, as shown in Figure 1 , Figure 2 and Figure 3 it is worth specifically stating that the first synchronous pulley 4 and the second synchronous pulley 6 are at the same horizontal height. Under the action of the synchronous belt 7, the first synchronous pulley 4 can follow and rotate.

[0025] Further, as shown in Figure 1 , Figure 2 and Figure 3 it is worth specifically stating that the output end of the driving motor 8 penetrates through the workbench 1 and is fixedly connected to the second rotating shaft 5, ensuring that the driving motor 8 can drive the second rotating shaft 5 to rotate smoothly, thereby providing a driving force for the rotation of the frustum 9.

[0026] According to the above working process, it can be known that by setting the driving motor 8 to drive the second synchronous pulley 6 to rotate, under the action of the synchronous belt 7, the first synchronous pulley 4 follows and rotates, so that the first rotating shaft 3 drives the frustum 9 to rotate, and the two clamping mechanisms 10 at the top of the frustum 9 move cyclically, and the loading and unloading can be completed while the aluminum gasket is being stamped, shortening the processing procedure and effectively improving the production efficiency of the aluminum gasket.

[0027] Further, as shown in Figure 4As shown, it is worth explaining in detail that the clamping mechanism 10 includes a stamping plate 1001 fixedly connected to the top of the truncated table 9, a plurality of stamping holes 1002 are opened on the top of the stamping plate 1001, convex frames 1003 are fixedly connected to the top of the stamping plate 1001 near the two sides, the inner walls of the front and rear ends of the two convex frames 1003 are slidably connected to the limiting slides 1004, and a clamping plate 1005 is fixedly connected between every two corresponding limiting slides 1004, the tops of the two clamping plates 1005 are rotatably connected to threaded rods 1006, the tops of the two threaded rods 1006 are fixedly connected to turntables 1007, and the tops of the two clamping plates 1005 are fixedly connected to two guide rods 1008. By setting the clamping mechanism 10, the clamping plate 1005 can stably clamp the metal aluminum sheet to avoid the metal aluminum sheet from being shaken by impact during the stamping process, thereby ensuring the production quality of the aluminum gasket.

[0028] Further as Figure 4 As shown, it is worth explaining in detail that the inner walls of the front and rear ends of the two convex frames 1003 are provided with limiting slide grooves corresponding to the limiting slide plate 1004, and the tops of the two convex frames 1003 are provided with two sliding holes corresponding to the guide rod 1008, and the limiting slide grooves and the sliding holes respectively play a role of limiting and guiding the movement of the limiting slide plate 1004 and the guide rod 1008, so that the lifting and lowering of the splint 1005 is more stable and avoids deviation.

[0029] Further as Figure 4 As shown, it is worth explaining in detail that the bottom of the two splints 1005 are fixedly connected with anti-slip strips, and the tops of the two convex frames 1003 are provided with threaded grooves corresponding to the threaded rods 1006. The threaded grooves cooperate with the threaded rods 1006 to ensure that the threaded rods 1006 can be raised and lowered while rotating, thereby driving the splints 1005 to be flexibly raised and lowered.

[0030] This solution has the following working process: in actual use, the metal aluminum sheet to be stamped is placed on the top of the stamping plate 1001, and the turntable 1007 is rotated to drive the threaded rod 1006 to rotate. The threaded rod 1006 drives the clamping plate 1005 to descend while rotating. The clamping plate 1005 descends to stably clamp the metal aluminum sheet, and then the drive motor 8 is turned on to drive the second synchronous wheel 6 to rotate. Under the action of the synchronous belt 7, the first synchronous wheel 4 follows the rotation, so that the round table 9 rotates and stops at the specified position. The stamping die 12 is opened to stamp the metal aluminum sheet. While stamping, the staff can load the material to another clamping mechanism 10, and the loading and unloading can be completed while the stamping operation is in progress.

[0031] In summary: By setting the driving motor 8 to drive the second synchronous pulley 6 to rotate, under the action of the synchronous belt 7, the first synchronous pulley 4 rotates accordingly, so that the first rotating shaft 3 drives the frustum 9 to rotate, and the two clamping mechanisms 10 at the top of the frustum 9 move cyclically, enabling loading and unloading to be completed simultaneously during the stamping of aluminum washers, shortening the processing procedures, and effectively improving the production efficiency of aluminum washers; by setting the clamping mechanism 10, the clamping plate 1005 stably clamps the metal aluminum sheet, preventing the metal aluminum sheet from shaking due to impact during stamping and ensuring the production quality of aluminum washers.
