DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 6 As shown, the utility model provides the following technical solutions: a thrust washer outer circle processing fixture, comprising: an operating table 1, a support plate 2 is provided above the operating table 1, a rotating assembly is connected to the lower end of the support plate 2, a support column 3 is installed on the upper end surface of the support plate 2, a bearing plate 4 is installed on the top of the support column 3, a hydraulic telescopic rod 5 is installed on the bottom end of the bearing plate 4, a connecting plate 6 is installed on the output end of the hydraulic telescopic rod 5, a hollow cylinder 7 is installed on the lower end surface of the connecting plate 6, an air guide duct 10 is connected to the hollow cylinder 7, a piston plate 9 is installed in the hollow cylinder 7, a spring 11 is installed between the piston plate 9 and the connecting plate 6, a movable plate 8 is connected to the lower end surface of the piston plate 9, a mounting plate 12 is connected to the bottom end of the movable plate 8, and an adjustable fixture assembly is provided on the mounting plate 12.

[0023] Furthermore, the rotating assembly includes a second motor 21, a second rotating shaft 22, a rolling groove 23 and a rolling ball 24. The second motor 21 is installed below the operating table 1, the second rotating shaft 22 is connected to the output end of the second motor 21, and the end of the second rotating shaft 22 away from the second motor 21 is connected to the lower end surface of the support plate 2, the rolling groove 23 is opened on the upper end surface of the operating table 1, and the rolling ball 24 is installed in the rolling groove 23.

[0024] Furthermore, an anti-dropping block 17 is installed at the bottom end of the inner wall of the hollow tube 7 , and an electronic valve is installed on the air guide pipe 10 .

[0025] Through the above technical solution:

[0026] When in use, start the second motor 21, and the second motor 21 drives the support plate 2 to rotate through the second rotating shaft 22. At this time, the rolling ball 24 rolls in the rolling groove 23, and then the sliding friction between the operating table 1 and the support plate 2 is converted into rolling friction, reducing friction and saving effort. The rotation of the support plate 2 can drive the upper support column 3, the bearing plate 4 and the clamp assembly to rotate together. After adjusting to a suitable position, start the hydraulic telescopic rod 5, and the hydraulic telescopic rod 5 drives the connecting plate 6 and the clamp assembly to move up and down. At the moment when the clamp assembly contacts the product, the movable plate 8 drives the piston plate 9 to move in the hollow cylinder 7, and the gas in the hollow cylinder 7 When the gas enters and exits the air duct 10, a certain damping force will be generated, thereby reducing the collision force between the clamp assembly and the product, thereby reducing the risk of scratches, deformation or damage to the product surface, helping to protect the quality and integrity of the product, as well as reducing the wear of the clamp assembly and equipment, extending the service life of the equipment, and reducing maintenance and replacement costs. After clamping is completed, the piston plate 9 is restored to its original position based on the product's own gravity and the elastic force of the spring 11, thereby ensuring the normal operation of the next buffering work. The anti-detachment block 17 makes it difficult for the hollow cylinder 7 to fall off from the piston plate 9, thereby improving the stability of the equipment.

[0027] See also Figure 1-Figure 3 As shown, the clamp assembly includes a suction cup 14 and a threaded rod 16. A plurality of movable grooves 13 are provided on the mounting plate 12. There are a plurality of suction cups 14, and the plurality of suction cups 14 are respectively installed in the plurality of movable grooves 13. A threaded groove 15 is provided on the mounting plate 12. The threaded rod 16 is screwed through the threaded groove 15, and the threaded rod 16 is connected to the suction cup 14 through a bearing.

[0028] Furthermore, a first motor 18 is installed on the connecting plate 6 , an output end of the first motor 18 is connected to a first rotating shaft 19 , and a protective plate 20 is installed on an outer wall of the first rotating shaft 19 .

[0029] Through the above technical solution:

[0030] When it is necessary to adjust the position of each suction cup 14, the threaded rod 16 is screwed, and the suction cup 14 is driven to move in the movable groove 13 through the interaction between the threaded rod 16 and the threaded groove 15, thereby adjusting the spacing between each suction cup 14. According to the requirements of product size, the equipment that can easily adjust the position of the suction cup 14 can adapt to products of different sizes and shapes, avoid frequent replacement of clamps, thereby improving production efficiency, reducing costs, and increasing the flexibility and automation level of the production line. After the suction cup 14 clamps the product, the first motor 18 is started. The first motor 18 drives the protective plate 20 to rotate through the first rotating shaft 19 until the protective plate 20 rotates to the bottom of the product. When the product is loose or falls off for some reason, the protective plate 20 can prevent the product from falling, thereby reducing the possibility of production line interruption and product loss.

[0031] For further information, see Figure 1 As shown, a support leg 25 is installed on the lower end surface of the operating platform 1, and a rolling wheel 26 is fixed to the bottom end of the support leg 25.

[0032] Specifically, the support legs 25 support the operating table 1 , and the rolling wheels 26 facilitate the movement of the entire device.
