Description

Technical Field

[0001] The utility model relates to the technical field of spring assembly, in particular to an automatic assembly device for a skeleton oil seal spring. Background Technique

[0002] The skeleton oil seal is a typical representative of oil seals. Generally, the oil seal mentioned refers to the skeleton oil seal. The function of the oil seal is generally to isolate the components that need lubrication in the transmission components from the external environment, so as to prevent the leakage of lubricating oil. The skeleton is like the steel bars in concrete components, playing a strengthening role and enabling the oil seal to maintain its shape and tension. According to the structural form, it can be divided into single-lip skeleton oil seals and double-lip skeleton oil seals. The secondary lip of the double-lip skeleton oil seal plays a dust-proof role, preventing external dust, impurities, etc. from entering the machine interior. According to the skeleton type, it can be divided into inner-packing skeleton oil seals, exposed-skeleton oil seals, and assembled oil seals.

[0003] In the prior art, most of the assembly steps in spring assembly are still manually operated, which not only has low production efficiency, but also has a high labor cost for spring assembly, and the yield of the assembled spring cannot be guaranteed.

[0024] The automatic assembly mechanism 2 includes a workbench 10. Sliders 16 are slidably connected to both the front and rear sides of the workbench 10. When the sliders 16 approach each other, the connecting plate 12 and the clamping block 13 will approach each other to clamp and fix the spring body 14. Connecting blocks 17 are fixedly connected to the middle of the bottom walls of the sliders 16. Clamping cylinders 18 are fixedly connected to the middle of the mutually facing side walls of the two groups of connecting blocks 17. When the output ends of the clamping cylinders 18 extend and retract, the two side sliders 16 will move away from or approach each other. The output ends of the clamping cylinders 18 are respectively fixedly connected to the middle of the front and rear walls of the moving block 20. Two groups of symmetrically arranged connecting plates 12 are fixedly connected to the mutually facing side walls of the sliders 16. Clamping blocks 13 are fixedly connected to the bottoms of the connecting plates 12. Limit blocks 25 are fixedly connected to the tops of the mutually facing side walls of the two groups of connecting blocks 17. An L-shaped plate 3 is fixedly connected to the middle of the front wall of the mounting block 1. A lifting cylinder 4 is fixedly connected to the middle of the top wall of the L-shaped plate 3. When the lifting cylinder 4 works, the lifting block 5 will move up and down. The output end of the lifting cylinder 4 is fixedly connected to the lifting block 5. An installation plate 6 is fixedly connected to the front side of the lifting block 5. A detection mechanism 7 is arranged on the left side of the bottom wall of the installation plate 6. A top-in mechanism 8 is arranged in the middle of the bottom wall of the installation plate 6. A spring extraction mechanism 9 is arranged on the right side of the bottom of the installation plate 6.

[0025] Among them, the limit blocks 25 are respectively slidably connected to the front and rear sides of the top of the moving block 20. Multiple groups of evenly distributed spring bodies 14 are arranged on the top wall of the workbench 10. The limit blocks 25 connect and fix the moving block 20 and the connecting block 17, so that the slider 16 can move along with the movement of the moving block 20.

[0026] Among them, the moving block 20 is slidably connected to the upper side of the guide plate 19. Support rods 15 are fixedly connected to the four corners of the bottom of the workbench 10, and the support rods 15 can fix the workbench 10 and the components on its upper side.

[0027] Among them, the detection mechanism 7, the top-in mechanism 8 and the spring extraction mechanism 9 are all located directly above the spring body 14. A pushing cylinder 26 is arranged on the right side of the bottom of the workbench 10, and the output end of the pushing cylinder 26 is fixedly connected to the moving block 20.

[0028] Among them, a blanking port 11 is arranged at the left end of the middle of the workbench 10. The blanking port 11 is located on the left side of the spring body 14, and the spring body 14 processed on the upper side of the workbench 10 is discharged through the blanking port 11.

[0029] Among them, a conveying table 22 is arranged on the right side of the workbench 10, and a feeding cylinder 23 is arranged at the rear end of the right side of the conveying table 22.

[0030] Among them, the output end of the feeding cylinder 23 is fixedly connected to a push block 24, and a stop block 21 is arranged at the rear end of the top of the conveying table 22.

[0031] Working principle: When assembling the spring body 14, the conveying table 22 conveys the spring body 14. During the conveying process of the spring body 14, it is blocked by the stopper 21. At this time, the working output end of the feeding cylinder 23 extends to drive the push block 24 to move leftward to push the spring body 14 onto the surface of the workbench 10. Then, the clamping cylinder 18 and the pushing cylinder 26 are started. The output end of the clamping cylinder 18 contracts to make the front and rear sliders 16 approach each other, so that the connecting plate 12 and the clamping blocks 13 approach each other. With the cooperation of the four groups of clamping blocks 13, the spring body 14 is clamped and fixed. At the same time, the output end of the pushing cylinder 26 produces a push to convey the spring body 14 to the lower side of the mounting plate 6. Then, the lifting cylinder 4 works to lower the detection mechanism 7, the jacking mechanism 8 and the spring extraction mechanism 9 to place, fix and detect the spring body 14, making the whole assembly process automated.
