A chamfering mechanism for the outer edge of the cut end surface of a steel pipe for an automobile shock absorber

Abstract

The utility model discloses a chamfering mechanism for the outer edge of the cut end face of a steel pipe of an automobile shock absorber, which relates to the technical field of steel pipe chamfering and comprises a bottom plate and mounting holes. The mounting holes are arranged in a group of two, and the two mounting holes are symmetrically distributed on the top of the bottom plate. The chamfering mechanism for the outer edge of the cut end face of a steel pipe of an automobile shock absorber is provided with a chamfering structure, which drives a positioning slider to move up and down by controlling a telescopic rod, thereby driving a driving rod to make corresponding up and down displacements. With the movement of the driving rod, it drives two rotating rollers to move in a vertical direction. In this process, the rotating rollers will slide inside a slide groove, and the positioning slider will also slide inside the driving rod. This sliding adjusts the distance between the fixed roller and the rotating roller. At the same time, with the change of this distance, the angle of the contact surface between the outer side of the grinding belt and the steel pipe will also change accordingly to adapt to different work requirements.

Description

Technical Field

[0002] Automobile shock absorbers are an important part of the vehicle suspension system, responsible for absorbing and alleviating the vibrations and impacts generated during the vehicle's driving. When the vehicle encounters bumpy or uneven roads during driving, the shock absorbers will absorb and disperse these impact forces through internal damping materials, thereby reducing the vibration and shaking of the vehicle body and ensuring the stability and comfort of the vehicle's driving.

DETAILED DESCRIPTION

[0026] 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.

[0027] In a further preferred embodiment of the present invention, Figure 4 - Figure 6 As shown, the inside of the mounting holes 2 are all engaged and connected with support frames 3, and four clamping rollers 4 are rotatably connected between the two support frames 3, and the four clamping rollers 4 are rotatably distributed between the two support frames 3, and a clamp is formed between the support frames 3 and the clamping rollers 4, both ends of the bottom plate 1 are fixedly connected with connecting blocks 7, and the top of the connecting block 7 is fixedly connected with a chamfering structure, the chamfering structure is provided with a moving frame 11, and two connecting holes 12 are provided on both sides of the moving frame 11, and slide grooves 13 are provided on both sides of the bottom plate 1, the inside of the moving frame 11 is fixedly connected with a positioning hole 15, and the inside of the positioning block 14 is provided with two symmetrically distributed positioning holes 15, a fixed roller 17 is rotatably connected between the two groups of connecting holes 12, and the outer sides of the two fixed rollers 17 are rotatably connected with a rotating roller 16, and the outer sides of the rotating roller 16 and the fixed roller 17 are rotatably connected with a grinding belt 18, the two ends of the rotating roller 16 are rotatably connected with driving rods 19, and the two driving rods 19 are slidably connected with positioning sliders 20, and the bottom of the positioning slider 20 is fixedly connected with a telescopic rod 21, the inside of the slide groove 13 is slidably connected with the two ends of a rotating roller 16, the fixed roller 17 and the rotating roller 16 are distributed in a parallelogram, and the grinding belt 18 is in a parallelogram shape outside the rotating roller 16 and the fixed roller 17, the top of the connecting block 7 is fixedly connected with a mounting plate 8, and the mounting plate 8 is fixedly connected with two symmetrically distributed positioning rods 9, one side of the connecting block 7 is fixedly connected with a hydraulic rod 10, and the moving end of the hydraulic rod 10 passes through one side of the mounting plate 8, the positioning rod 9 is slidably connected to the inside of the positioning hole 15, and the moving end of the hydraulic rod 10 is fixedly connected to one side of the positioning block 14, and the inside of the mounting plate 8 is slidably connected with the moving frame 11;

[0028] The positioning slider 20 is driven to move up and down by controlling the telescopic rod 21, thereby driving the driving rod 19 to move up and down accordingly. As the driving rod 19 moves, it will drive the two rotating rollers 16 to move in the vertical direction. During this process, the rotating roller 16 will slide inside the slide groove 13, and the positioning slider 20 will also slide inside the driving rod 19. This sliding adjusts the distance between the fixed roller 17 and the rotating roller 16. When the positioning slider 20 slides inside the driving rod 19, the positioning slider 20 will slide outside the multiple cross bars inside the driving rod 19, so that the driving rod 19 always maintains a vertical state with the telescopic rod 21.

[0030] The support frame 3 and the clamping roller 4 together constitute a clamping mechanism. First, operate the rotating frame 6 to rotate so that it rotates around the end of the fixed block 5 and gradually moves away from the base plate 1. Then, place the steel pipe in two clamps located on the top of the base plate 1 to ensure that the outer side of the steel pipe is tightly fitted with multiple clamping rollers 4. Rotate the rotating frame 6 again so that the clamps at its end firmly clamp the top of the steel pipe so that the steel pipe is fixed between the structure formed by the three clamps, thereby achieving the fixation of the steel pipe and facilitating the replacement of the steel pipe. When the steel pipe is fixed, start the clamping roller 4 at the end of the rotating frame 6 to drive the steel pipe to rotate between the three clamps, so that the chamfered part of the steel pipe rotates while contacting with the grinding belt 18 to grind the chamfered part.
