Description

Technical Field

[0001] The invention belongs to the technical field of shock absorber upper seat processing, and in particular relates to a shock absorber upper seat processing tool and a method thereof. Background Art

[0002] Automobile shock absorption is the vibration caused by the impact of elastic elements in the suspension system. In order to improve the driving smoothness of the car, a shock absorber is installed in parallel with the elastic element in the suspension. In order to attenuate the vibration, the shock absorber used in the automobile suspension system is mostly a hydraulic shock absorber. Its working principle is that when the frame (or body) and the axle are vibrated and there is relative movement, the piston in the shock absorber moves up and down. In the use of automobile shock absorbers, a compression spring seat is usually used at the spring position above the shock absorber to fix the spring and shock absorber. In the production process of the spring seat cap, generally after stamping, there will be a certain difference in shape, so the cap needs to be slightly cut.

[0003] Publication (Announcement) No.: CN210387965U discloses a device for processing a press cap on a spring seat of an automobile shock absorber, which relates to the technical field of automobile shock absorbers, and includes a base plate, a laser cutting mechanism is placed on the top of the base plate, and a clamping mechanism is installed inside the base plate. The device for processing a press cap on a spring seat of an automobile shock absorber drives a threaded rod to rotate in a threaded tube through the positive direction operation of servo motor 1, adjusts the position of the threaded tube, and thereby adjusts the cutting position of the laser generator, drives the rotating plate to rotate through the rotation of servo motor 2, drives the laser generator to rotate and adjust the cutting position, pushes the toothed plate below to move to the left through the extension of the telescopic end of the electric push rod, thereby driving the gear to rotate, drives the toothed plate above to move to the right during the rotation, and drives the two clamping rods to move in opposite directions, thereby clamping the inner cavity of the press cap, thereby better performing a trimming operation on it.

[0004] When the existing processing tooling is used, a punching machine is first used for punching, then a cutting machine is used to cut the outer edge, and finally a drilling machine is used to drill holes inside the stamped part. The operation is complicated and does not have the integrated functions of punching, cutting, and drilling, which reduces work efficiency.

[0005] In order to solve the above problems, the present application proposes a shock absorber upper seat processing tool and method. Summary of the invention

The debris generated by drilling or grinding is collected by the collection drawer box to avoid environmental pollution. The cooperation of the two matching blocks and the two matching grooves can facilitate the installation of the collection drawer box in the fixed box, and the collection drawer box can be taken out for cleaning;

[0083] Reference Figure 1-Figure 16 As shown, the present invention also proposes a method for using a shock absorber upper seat processing tool, comprising the following steps:

[0084] S1: Preparation before processing, connect the power supply and the controller 12, the controller 12 uses a conventional PLC controller;

[0085] S2: Take a metal circular plate and place it on the top of the lower die seat 6. The size and thickness of the metal circular plate are set according to the requirements, and the metal circular plate covers the outer side of the model groove 61 and the annular groove 63. The shock absorber upper seat 7 is a metal circular plate before processing.

[0086] S3: The circular plate 52 is driven downward by the two first cylinders 51, and the downward movement of the circular plate 52 drives the edge pressing member 57 to first contact the shock absorber upper seat 7 and squeeze the outer extension of the shock absorber upper seat 7. As the circular plate 52 continues to press downward, the spring 59 contracts and further presses the outer extension of the shock absorber upper seat 7. Then, the upper mold 53 cooperates with the mold groove 61 to process the convex part 72.

[0087] S4: Control the four second cylinders 56 to push the annular trimming knife 55 to move downward, and the annular trimming knife 55 cooperates with the annular cutting groove 63 to trim the edge of the shock absorber upper seat 7 to form an extension plate 71, and then the annular trimming knife 55 retracts upward to reset;

[0088] S5: The two linear motors 41 push the rotating rod 46, the hole-opening drill bit 48 and the grinding brush 47 to move downward and pass through the through hole 54. Since the diameter of the through hole 54 is larger than the diameter of the hole-opening drill bit 48 and the grinding brush 47, the hole-opening drill bit 48 and the grinding brush 47 will not contact the inner wall of the through hole 54 when passing through the through hole 54. The rotating rod 46 is driven to rotate by the servo motor 45, and the rotating rod 46 drives the hole-opening drill bit 48 to rotate to drill the shock absorber upper seat 7 to form a circular hole 73. The grinding brush 47 continues to move downward to grind and remove burrs on the circular hole 73 of the shock absorber upper seat 7. The debris generated by drilling or grinding is collected by the collecting drawer box 23 to avoid polluting the environment. The cooperation of the two matching blocks 27 and the two matching grooves 26 can facilitate the installation of the collecting drawer box 23 in the fixing box 21, and the collecting drawer box 23 can be taken out for cleaning;

[0089] S6: After the processing is completed, the two linear motors 41 are controlled in reverse, so that the grinding brush 47 and the hole drill 48 leave the through hole 54, and the two first cylinders 51 are started in reverse to drive the upper model 53 to leave the model groove 61, and then the edge clamp 57 leaves the shock absorber upper seat 7. After the spring 59 is elastically reset, the shock absorber upper seat 7 can be taken out.
