All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0031] Please refer to Figure 1-3 A squeezing device for spring testing includes a workbench 1, two adjusting seats 2 are fixedly installed at equal distances on the top of the workbench 1, an adjusting motor 3 is fixedly installed on the top of one of the two adjusting seats 2, and a limiting sliding hole 4 is provided on one side of the two adjusting seats 2. A fixed box 5 is fixedly installed at the center position of the top of the workbench 1, a fixed motor 6 is fixedly installed on one side of the fixed box 5, an L-shaped support 7 is fixedly installed on the top of the workbench 1 at the rear side of the fixed box 5, a cylinder 8 is fixed on the L-shaped support 7, and a hydraulic rod is provided at the bottom of the cylinder 8.

[0032] Reference Figure 2 and Figure 3 A pressure plate 9 is fixedly connected to the horizontal surface of the bottom end of the hydraulic rod, and a pressure detector 10 is provided at the bottom of the pressure plate 9. The hydraulic rod can drive the pressure plate 9 to move downward, and the pressure detector 10 moves downward to perform extrusion detection on the spring.

[0033] Reference Figure 2 and Figure 3 , a fixing mechanism is provided in the fixing box 5, and the spring to be tested can be fixed by using the fixing mechanism. The fixing mechanism includes a driving rod 11, which is rotatably connected to the inner wall of one side of the fixing box 5. The driving rod 11 is fixedly connected to the output shaft of the fixing motor 6. One end of the driving rod 11 is fixedly connected to a worm 12, and a fixed screw 13 is rotatably connected in the fixing box 5. A worm wheel 14 is fixedly connected to the center of the outer wall of the fixed screw 13. The worm wheel 14 is meshed with the worm 12. The meshing between the worm 12 and the worm wheel 14 allows the driving rod 11 to transmit the fixed screw 13. In operation, both ends of the fixing screw 13 are threadedly connected with a fixing screw sleeve 15, and the two fixing screw sleeves 15 are fixedly connected with a long plate 16. The two long plates 16 are slidably connected to the inner wall of the fixed box 5, and the corresponding sides of the two long plates 16 are fixedly connected with a fixing plate 17. The two fixing plates 17 cooperate with each other. Since the thread directions of the two ends of the fixing screw 13 are opposite to the thread directions of the two fixing screw sleeves 15, the two fixing screw sleeves 15 can drive the two long plates 16 to approach each other, and the two long plates 16 drive the two fixedly connected fixing plates 17 to approach each other to fix the spring to be tested.

[0034] Reference Figure 2 and Figure 3, a protective mechanism is provided on the two adjustment seats 2, which can be used to protect the springs during testing to avoid damage and injury. The protective mechanism includes two adjusting screws 18, which are rotatably connected to the two adjustment seats 2 respectively. One of the two adjusting screws 18 is fixedly connected to the output shaft of the adjusting motor 3. A transmission wheel 19 is fixedly connected to the horizontal surface of the bottom end of the two adjusting screws 18. A transmission belt 20 is connected between the two transmission wheels 19. The transmission belt 20 transmitted between the two transmission wheels 19 is used to make the two adjusting screws 18 rotate synchronously. An adjusting screw sleeve 21 is threadedly connected to the two adjusting screw sleeves 21, and a fixed connection is provided on the two adjusting screw sleeves 21. The adjusting plate 22, the two adjusting plates 22 are respectively slidably connected to the two limiting sliding holes 4, and one end of the two adjusting plates 22 is hinged with a push-pull rod 23. Since the two adjusting plates 22 fixedly connected to the adjusting screw sleeve 21 are slidably limited with the two limiting sliding holes 4, the two adjusting plates 22 drive the two hinged push-pull rods 23 to move downward, and make the bottom ends of the two push-pull rods 23 approach each other. The top of the workbench 1 is symmetrically slidably connected to two protective shells 24, and the two protective shells 24 are fixedly connected with a connecting seat 25. The two connecting seats 25 are respectively hinged to one end of the two push-pull rods 23. When the bottom ends of the two push-pull rods 23 approach each other, the two push-pull rods 23 can drive the two protective shells 24 to approach each other through the two hinged connecting seats 25.

[0035] Reference Figure 2 and Figure 3 A controller 26 is provided on the front side of the workbench 1, and arc-shaped notches are provided on the two protective shells 24. The two arc-shaped notches are adapted to the hydraulic rod. When the two arc-shaped notches 27 surround the outside of the hydraulic rod and there is a gap with it, it will not affect the normal operation of the hydraulic rod.

[0036] The implementation principle of the present invention is as follows: when using the extrusion device for spring detection, first, the spring to be detected is placed between the two fixed plates 17 in the fixed box 5, and the fixed motor 6 is started by the controller 26, so that the output shaft of the fixed motor 6 drives the driving rod 11 to rotate, and the driving rod 11 drives the fixed screw 13 fixedly connected to the worm gear 14 to rotate through the engagement between the worm 12 and the worm gear 14. Since the thread directions of the two ends of the fixed screw 13 are respectively opposite to the thread directions of the two fixed screw sleeves 15, and at the same time, the sliding between the two long plates 16 and the inner wall of the fixed box 5 makes the fixed When the screw 13 rotates, it can drive the two threaded fixed screw sleeves 15 to approach each other, the two fixed screw sleeves 15 drive the two long plates 16 to approach each other, and the two long plates 16 drive the two fixedly connected fixed plates 17 to approach each other to fix the spring to be tested. Then the controller 26 is used to control the cylinder 8 to drive the hydraulic rod to move downward, and the hydraulic rod drives the pressure plate 9 fixed at the bottom to move downward. When the pressure plate 9 is located in the fixed box 5, the controller 26 is used to start the adjustment motor 3, so that the output shaft of the adjustment motor 3 drives one of the two adjusting screws 18 to rotate. Since the two adjusting screws 18 are fixedly connected to the transmission wheel 19, and the two transmission wheels 19 are transmitted with a transmission belt 20, the two adjusting screws 18 rotate synchronously. Since the two adjusting plates 22 fixedly connected to the adjusting screw sleeves 21 slide and limit with the two limiting slide holes 4, the two adjusting screws 18 drive the two adjusting screw sleeves 21 to move downward, the two adjusting screw sleeves 21 drive the two adjusting plates 22 to move downward, and the two adjusting plates 22 drive the two hinged push-pull rods 23 to move downward, and make the bottom ends of the two push-pull rods 23 approach each other, and the two push-pull rods 23 are hinged to each other. The connecting seat 25 drives the two protective shells 24 to approach each other. At the same time, the two arc-shaped notches 27 surround the outside of the hydraulic rod and have a gap with it, which will not affect the normal operation of the hydraulic rod. When the two protective shells 24 are close to each other and fit together, the fixed box 5 can be covered, and then when the spring to be tested is tested, the protection effect is achieved, thereby avoiding the situation where the spring that does not meet the quality standards is damaged and pops out, causing hidden dangers to the staff. The controller 26 is then used to control the cylinder 8, so that the hydraulic rod drives the pressure plate 9 to move downward, and the pressure detector 10 moves downward to perform an extrusion test on the spring to be tested.
