DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] During specific implementation: As Figures 1-5 shown, a positioning fixture for the processing of cast aluminum pistons with an adjusting effect includes a support base 1 and a support plate 9: A support plate 9 is provided at the upper end of the support base 1, and the support plate 9 is slidably connected to the support base 1. A clamping structure 16 is provided at the upper end of the support base 1;
[0024] The clamping structure 16 includes a second motor 14, a second threaded rod 15, and a clamping block 12. A second motor 14 is provided at the upper end of the support base 1, a second threaded rod 15 is provided on the side of the second motor 14, and a clamping block 12 is provided on the side of the support plate 9;
[0025] When the device is in use, first fix the device at the processing position through the mounting holes on the surface of the mounting base 4, and then place the piston to be processed on the surface of the placement table 10. Turn on the second motor 14 to drive the second threaded rod 15 to rotate. Since the threads on the surface of the second threaded rod 15 are opposite, drive the support plate 9 to move inward on the surface of the second threaded rod 15 at the same time, so that the support plate 9 pushes the clamping block 12 to move inward at the same time, and the clamping block 12 clamps and fixes both sides of the piston. Then start processing the piston, so as to make the device adapt to pistons of different lengths and improve the practicability of the device.
[0026] The second threaded rod 15 is threadedly connected to the support plate 9, and a placement table 10 is provided at the upper end of the support base 1;
[0027] The placement table 10 is trapezoidally arranged, and a groove is provided at the upper end of the placement table 10;
[0028] When the device is in use, first place the piston on the surface of the placement table 10, and multiple pistons can be placed according to the grooves on the surface of the placement table 10, so that the device can clamp and fix multiple pistons at the same time, and the processing equipment can process the surfaces of multiple pistons at the same time.
[0029] A first motor 11 is provided on the side of the support plate 9, a friction pad 13 is provided on the side of the clamping block 12, and the first motor 11 penetrates through the friction pad 13;
[0030] When the device is in use, after clamping and fixing a piston, during processing, the first motor 11 is turned on at this time, so that the first motor 11 drives the clamping block 12 to rotate, thereby driving the piston to rotate, exposing the surface to be processed of the piston, enabling the processing equipment to completely process the surface of the piston, and preventing manual rotation of the piston. Moreover, through the setting of the friction pad 13, the friction force between the piston and the clamping block 12 can be increased to prevent the piston from falling off the surface of the clamping block 12.
[0031] A connecting block 2 is provided at the lower end of the support base 1, and a rotating shaft 6 is provided on the side of the connecting block 2;
[0032] A first threaded rod 7 is provided inside the connecting block 2, and a sliding block 8 is provided on the surface of the first threaded rod 7. The sliding block 8 is threadedly connected to the first threaded rod 7;
[0033] When the device is in use, when it is necessary to process the surfaces of multiple pistons simultaneously, the processing equipment can only process the piston at one of the lower positions. At this time, the rotating shaft 6 is rotated, so that the rotating shaft 6 drives the first threaded rod 7 to rotate, causing the sliding block 8 to move on the surface of the first threaded rod 7, driving the support base 1 to move, enabling the support base 1 to drive the placement table 10 to move, so that the processing equipment can move different pistons to the position below the processing equipment for processing without moving, thereby improving the processing efficiency of the pistons.
[0034] A telescopic rod 3 is provided at the lower end of the connecting block 2, and a mounting seat 4 is provided at the lower end of the telescopic rod 3;
[0035] A hydraulic press 5 is provided at the upper end of the mounting seat 4, and mounting holes are provided on the surface of the mounting seat 4;
[0036] When the device is in use, since the heights of different processing equipments are different, the device needs to be able to adapt to processing equipments of different heights. At this time, the hydraulic press 5 is turned on, so that the hydraulic press 5 pushes the connecting block 2 upward and the telescopic rod 3 extends upward, thereby raising the device to move the piston below the processing equipment, so as to enable the device to adapt to processing equipments of different heights.
[0037] When the utility model is in use, first, the device is installed under the processing equipment through the mounting holes on the surface of the mounting base 4. Subsequently, the hydraulic press 5 is turned on, and the hydraulic press 5 moves upward to push, so as to drive the connecting block 2 to drive the support base 1 to move upward, so that the placing table 10 is located under the processing equipment. Subsequently, the piston is placed on the surface of the placing table 10, and the second motor 14 is turned on, so that the second motor 14 drives the second threaded rod 15 to rotate, so that the support plate 9 moves inward on the surface of the second threaded rod 15 at the same time, so that the support plate 9 pushes the clamping block 12 to move inward, and the friction pad 13 is attached to the piston, so as to clamp and fix the piston. Subsequently, the surface of the piston is processed by the processing equipment. Subsequently, the first motor 11 is turned on, so that the first motor 11 drives the clamping block 12 to rotate, so as to drive the piston to rotate, so that the processing equipment can completely process the surface of the piston, reducing the steps that manual labor needs to rotate the piston and improving the processing efficiency of the piston.
