[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Reference Figure 1-4A jig for machining non-standard parts includes a base 1, a drive assembly at the bottom of the base 1, and a rotating rod 7 connected to the bottom of the base 1 via the drive assembly. The drive assembly includes a fixed plate 2 at the bottom of the base 1, a drive motor 3 fixedly mounted on the right side of the fixed plate 2, a first pulley 4 fixedly mounted at the output end of the drive motor 3, a synchronous belt 5 meshing with the surface of the first pulley 4, and a second pulley 6 meshing with the inner wall of the synchronous belt 5. The second pulley 6 is fixedly connected to the rotating rod 7. The drive assembly facilitates the provision of driving force for the rotation of the rotating rod 7. A connecting plate 8 is rotatably connected to the surface of the rotating rod 7, and the connecting plate 8 is fixedly connected to the base 1. A transmission assembly is provided on the surface of the rotating rod 7, and a rotating shaft 11 is provided on the surface of the rotating rod 7 through the transmission assembly. The rotating shaft 11 is rotatably connected to the base 1. The transmission assembly includes a first bevel gear 9 provided on the surface of the rotating rod 7, and a second bevel gear 10 meshing on the surface of the first bevel gear 9. The second bevel gear 10 is fixedly connected to the rotating shaft 11. The transmission assembly facilitates transmission during the rotation of the rotating rod 7, thereby facilitating the rotation of the rotating shaft 11 and the clamping block. 17. Switching is performed so that the fixture can be used to clamp and fix various types of non-standard parts. A connecting block 12 is fixedly installed on the top of the rotating shaft 11, and a first electric push rod 13 is fixedly installed on the side of the connecting block 12. The output end of the first electric push rod 13 is provided with a mounting component, and the output end of the first electric push rod 13 is provided with a clamping block 17 through the mounting component. This non-standard part processing fixture, according to the shape of the non-standard part, causes the rotating rod 7 to rotate through the drive component, so that the transmission component can transmit power, so that the rotating shaft 11, the first electric push rod 13, and the mounting block 17 can be clamped together. The component and clamping block 17 rotate to switch the clamping block 17. After the switch is completed, the non-standard part is placed between the clamping blocks 17. The first electric push rod 13 causes the mounting component and clamping block 17 to move towards the non-standard part, so that the clamping block 17 makes close contact with the non-standard part and fixes it. This makes the fixture applicable to clamping and fixing non-standard parts of various shapes. It can ensure that the parts remain stable during processing, reduce processing errors caused by part shaking or displacement, and improve processing accuracy and product quality.
[0023] according to Figure 1 and Figure 4As shown, the mounting assembly includes a mounting block 14 disposed at the output end of the first electric push rod 13. A slot 15 is provided on the side of the mounting block 14, and a plug 16 is inserted into the slot 15. The plug 16 has a T-shaped structure and is made of stainless steel to ensure higher structural strength and durability. The plug 16 is adapted to the slot 15 and is fixedly connected to the clamping block 17. A second electric push rod 18 is fixedly mounted on the side of the mounting block 14, and a limit block 19 is fixedly mounted at the output end of the second electric push rod 18. The limit block 19 is slidably connected to the mounting block 14. During disassembly, the second electric push rod 18 moves the limit block 19 away from the slot 15. The direction is moved so that the limiting block 19 can no longer limit the insertion block 16. Then, the insertion block 16 can be pulled out from the slot 15 to complete the disassembly of the clamping block 17. During installation, the insertion block 16 on the clamping block 17 is inserted into the slot 15. Then, the second electric push rod 18 moves the limiting block 19 toward the slot 15 so that the limiting block 19 moves to the appropriate position to limit the insertion block 16 and complete the fixation of the clamping block 17. Through the setting of the installation component, the clamping block 17 can be detached and installed, which makes it easy to replace the clamping block 17 according to the shape of the non-standard parts to be processed. This makes it easier for the clamping block 17 to be better used for clamping and fixing non-standard parts in the future.
[0024] according to Figure 1 As shown, a mounting bracket 20 is fixedly installed on the bottom of the base 1. The mounting bracket 20 has a through mounting hole 21 at the bottom. The mounting bracket 20 can be fixed to a suitable position on the machine tool by bolts through the mounting hole 21, which facilitates the installation of the fixture.
[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.
[0026] In use: The mounting bracket 20 can be fixed to a suitable position on the machine tool using bolts through the mounting holes 21. The insert block 16 on the corresponding clamping block 17 is inserted into the slot 15. Then, the second electric push rod 18 moves the limiting block 19 towards the slot 15, positioning it to a suitable position and limiting the insert block 16, thus fixing the clamping block 17. Based on the shape of the non-standard part, the drive motor 3 is started, causing the first pulley 4 to rotate, which in turn causes the synchronous belt 5 to drive the second pulley 6 to rotate, thus rotating the rotating rod 7. This causes the first bevel gear 9 to rotate, the second bevel gear 10 to rotate, and the rotating shaft 11 to rotate. This causes the connecting block 12, the first electric push rod 13, the mounting block 14, and the clamping block 17 to rotate, switching the clamping block 17. After switching, the non-standard part is placed between the clamping blocks 17. The first electric push rod 13 causes the mounting block 14 to move toward the non-standard part, and the clamping block 17 to move toward the non-standard part, so that the clamping block 17 makes close contact with the non-standard part, thereby fixing it.
