Abstract
Description
Technical Field

[0002] Circlip products are a common mechanical elastic element, usually made of spring steel or stainless steel. They have a flat or round shape, usually a semicircular or wavy shape. Circlip products play the role of fixing, connecting or providing elastic support in many applications. Circlip products can provide stable support and pressure through their elastic force. They can produce elastic deformation when subjected to force and return to their original shape after the force is removed.

[0027] When in use, first place the spring clip product on the upper part of the placement plate 18. Then, start the electric push rod 9, and the output end of the electric push rod 9 is fixedly connected to the moving block 10, thereby driving the moving block 10 to move downward. The outside of the moving block 10 is rotatably connected to the two connecting plates 11, so when the moving block 10 moves, the two connecting plates 11 will also move accordingly. The other ends of the two connecting plates 11 are respectively rotatably connected to the two sliding blocks 14, and the two sliding blocks 14 move relatively outside the two fixed rods 13. When the sliding blocks 14 move, they will drive the two mounting rods 15 fixedly connected at the upper part to move relatively. The outsides of the two mounting rods 15 are fixedly connected to two arc-shaped card plates 16, so when the mounting rods 15 move, the arc-shaped card plates 16 will also move relatively. Two protective pads 17 are arranged inside the arc-shaped card plates 16, and the two protective pads 17 will also move when the arc-shaped card plates 16 move relatively. Through the relative movement of the two protection pads 17, the retaining spring product placed on the placement plate 18 can be fixed, so that retaining spring products of different sizes can be easily fixed to meet the testing requirements of different retaining spring products and improve the applicability of the testing tooling.

[0029] First, the operator needs to take out four circlip products to be tested and fix them on the upper part of four fixing plates 7. Next, as the hydraulic cylinder 21 is started, it drives the mounting block 22 to start moving. The lower part of this mounting block 22 is equipped with a test press block 23 for strength testing of the circlip products. The precise control of the hydraulic cylinder 21 ensures that the test press block 23 can perform pressure testing on the circlip products with appropriate force to evaluate their quality and performance. After completing the strength test of the first circlip product, the rack plate 302 starts to move by starting the cylinder 301. This rack plate 302 is connected to the external meshing gear 304, so when the rack plate 302 moves, the gear 304 will also rotate accordingly. The inside of the gear 304 is fixedly connected to the rotating column 305, so the rotation of the gear 304 will drive the rotation of the rotating column 305. The top of the rotating column 305 is fixedly connected to the rotating table 306, which means that the rotation of the rotating column 305 will drive the rotation of the rotating table 306. The outer periphery of the rotating platform 306 is fixedly connected with connecting rods 6, which are connected to the fixed plate 7. Therefore, when the rotating platform 306 rotates, it drives the four connecting rods 6 and the fixed plate 7 to rotate together. This series of mechanical actions ensures that the circlip product to be tested can be accurately moved to the lower part of the test block 23, so as to carry out the next force test, and realizes that by fixing multiple circlip products and testing multiple circlip products at one time, the efficiency of the test can be greatly improved. There is no need to fix the circlip products one by one, which saves the time of fixing and adjusting the tooling, thereby speeding up the entire test process.

[0031] During the test, the strength test of the retaining spring product can be completed by starting the hydraulic cylinder 21 to move the mounting block 22 fixedly connected to the output end, and the movement of the mounting block 22 moves the test pressure block 23 installed at the bottom. The guide ring 26 is slidably connected to the outside of the guide rod 24 to play a guiding role. The display screen 20 is set to facilitate viewing the test results of each retaining spring product.
[0032] Working principle: when it is necessary to fix the spring clip products of different sizes, first place the spring clip products on the upper part of the placement plate 18, and then start the electric push rod 9, the electric push rod 9 moves downward with the moving block 10 fixedly connected to the output end, the moving block 10 moves with the connecting plates 11 connected to the external sides, the two connecting plates 11 move with the two sliding blocks 14 connected to the other ends to move relative to each other outside the two fixed rods 13, when the two sliding blocks 14 move relative to each other, the two mounting rods 15 fixedly connected on the upper part move relative to each other, the two mounting rods 15 move relative to each other, the two arc-shaped clamping plates 16 fixedly connected on the outside move relative to each other, the two arc-shaped clamping plates 16 move relative to each other, the two protective pads 17 arranged inside move relative to each other, and the spring clip products placed on the upper part of the placement plate 18 can be fixed by the relative movement of the two protective pads 17, so that the spring clip products of different sizes can be easily fixed to meet the testing requirements of different spring clip products and improve the applicability of the testing tooling, and then the spring clip products can be tested. When testing, first take out four retaining ring products that need to be tested and fix them on the upper part of the four fixed plates 7. After the fixing is completed, the hydraulic cylinder 21 moves the mounting block 22 fixedly connected to the output end, and the mounting block 22 moves with the test pressing block 23 installed at the lower part to test the strength of the retaining ring product. After the test, by starting the cylinder 301, the cylinder 301 moves the rack plate 302 fixedly connected to the output end, and the rack plate 302 moves and rotates the gear 304 engaged with the outside. The rotation of the gear 304 rotates the rotating column 305 fixedly connected inside, and the rotation of the rotating column 305 rotates the rotating table 306 fixedly connected at the top. The rotating table 306 rotates and rotates the connecting rods 6 fixedly connected on all sides outside. The four connecting rods 6 rotate and rotate the four fixed plates 7 fixedly connected outside. The retaining plate 7 rotates to move the retaining ring product to be tested to the lower part of the test pressing block 23 for testing, so that multiple retaining ring products can be fixed and tested at one time, which can greatly improve the efficiency of the test.
