Description

Technical Field

[0001] The utility model belongs to the technical field of riveting machines and relates to a riveting mechanism for a shock absorber connecting rod. Background Art

[0002] The shock absorber is a device used to suppress the shock caused by the rebound of the spring after absorbing the shock and the impact from the road surface. The shock absorber assembly consists of a shock absorber, a lower spring pad, a dust cover, a spring, a shock pad, an upper spring pad, a spring seat, a bearing, a top rubber, and a nut. The inside of the shock absorber is filled with oil. There is one or more holes on the piston head of the shock absorber. When the shock absorber moves up and down, the oil in the cavity flows back and forth between the upper and lower end cavities through the small holes on the piston head. Because the oil is viscous, it also releases a lot of heat, which is equivalent to converting the kinetic energy generated by the vehicle's bumps into heat energy. In terms of materials, shock absorbers can be divided into hydraulic and pneumatic types. Shock absorbers are widely used in automobiles. In order to accelerate the attenuation of the vibration of the frame and body and improve the smoothness of the car's ride, the connecting rod is an important component of the shock absorber and is usually processed using a riveting machine.

[0003] When using a riveting machine to process the existing shock absorber connecting rod, the connecting rod needs to be placed in the upper and lower grooves and needs to be manually fixed to prevent it from tipping over; and while waiting for the drill rig to descend and tighten the nut in the middle, the connecting rod needs to be pressed inward manually to prevent it from rotating with the drill bit and causing processing failure. Long-term manual squeezing greatly consumes employees' physical strength and reduces work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings.

[0028] like Figure 1-7As shown, a shock absorber connecting rod riveting mechanism includes an assembly line 1, a riveting machine 2 is installed on one side of the assembly line 1, an operating table 3 is fixedly installed on the lower outer wall of the riveting machine 2, connecting plates 4 are installed on both sides of the operating table 3, a pin shaft 41 is arranged on the inner side of the connecting plate 4, a fixing plate 42 is installed on the top of the pin shaft 41, a bolt 43 is installed through one side of the fixing plate 42, and a base 5 is movably installed in the middle of the connecting plate 4, a U-shaped rod 51 is fixedly installed on the base 5, and an upper notch 5 is opened on the upper side of the U-shaped rod 51. 2, a lower notch 53 is installed at the lower side of the upper notch 52, and a notch 6 penetrating the outer wall is opened on the outer side of the upper notch 52 and the lower notch 53, and a through hole 61 is opened at the lower notch 53 of the base 5, and a rotating block 7 is installed at the lower notch 53, and a handle 71 is installed on the outer wall of the rotating block 7, and a movable block 8 is installed on the inner side of the rotating block 7, and a groove 81 is opened at one end of the movable block 8, and a fixing hole 82 is opened at the other end of the movable block 8, and a slide rail 9 is arranged on the base 5, and a spring 91 is installed on the inner wall of the slide rail 9.

[0029] Combination Figure 1 As shown, a conveyor belt 11 is designed in the middle of the assembly line 1, and a plurality of conveyor blocks 12 are installed in the conveyor belt 11. Fixed blocks 13 are symmetrically installed on the conveyor blocks 12, and connecting rods 14 are provided on the fixed blocks 13.

[0030] Furthermore, the assembly line 1 is of an existing structure, in which a power device is installed to drive the conveyor belt 11 to pull the conveying block 12 to move at a constant speed, and the interior of the connecting rod 14 is hollow and can be directly inserted into the fixed block 13.

[0031] Combination Figure 2 As shown, a control box is installed on one side of the riveting machine 2, and a drill bit is installed below the drill 21.

[0032] Furthermore, the riveting machine 2 is internally provided with a device which can not only drive the drill bit to rotate, but also can pull the drill bit to move vertically regularly, so as to cooperate with manual tightening of the nut on the top of the connecting rod 14 in the shock absorber.

[0033] Combination Figure 2 , Figure 3 As shown, the operating table 3 is symmetrically provided with a plurality of threaded holes 31 penetrating the outer wall, the threaded holes 31 and the bolts 43 are meshed with each other, and the operating table 3 and the connecting plate 4 are fitted with each other. The pin 41 is rotatably connected to the connecting plate 4 and the fixing plate 42 respectively, and the fixing plate 42 is provided with a through hole 61 penetrating the outer wall, and the bolts 43 are inserted into the through hole 61.

[0034] Furthermore, since different bases 5 and U-shaped rods 51 need to be replaced for connecting rods 14 of different sizes, the spacing between the fixing plates 42 on both sides also needs to be changed accordingly. This can be done by changing the bolting position of the bolts 43. The bolts 43 are used as force points, and the connecting plates 4 and fixing plates 42 on both sides cooperate with each other to fix the base 5. The rotating fixing plates 42 can have an adjustable angle.

[0035] Combination Figure 2 , Figure 3 As shown, the upper notch 52 is in the shape of an inverted truncated cone, and the upper opening size of the upper notch 52 is larger than the lower opening size, and the lower notch 53 and the lower opening size of the upper notch 52 are the same.

[0036] Furthermore, by setting the upper groove 52 to an inverted truncated cone shape, when the connecting rod 14 is placed, the connecting rod 14 automatically falls due to the gravity factor, and its top will be located in the upper groove 52, and will not fall down without human support.

[0037] Combination Figure 4 , Figure 7 As shown, a pin 41 is installed through the rotating block 7, and the rotating block 7 is rotatably installed through the pin 41 and the base 5, and the rotating block 7 and the pin 41 are eccentrically installed. Slide blocks are symmetrically installed below the movable block 8, and the movable block 8 is slidably connected through the slide block and the slide rail 9, and the size of the groove 81 is larger than that of the rotating block 7.

[0038] Furthermore, the rotating block 7 is eccentrically rotatably installed through the pin shaft 41 and the base 5. When the rotating block 7 is rotated by the handle 71, the rotating block 7 body on the other side will be embedded in the groove 81, so that the movable block 8 can move.

[0039] Combination Figure 4 , Figure 7 As shown, the movable block 8 has the same shape as the notch 6 at one end of the fixing opening 82, and the size here is smaller than the notch 6. One end of the spring 91 is connected to the slide rail 9, and the other end of the spring 91 is connected to the slider below the movable block 8.

[0040] Furthermore, when the movable block 8 moves along the slide rail 9 through the slider, the internal spring 91 is deformed and compressed to generate a deformation force, and the fixing port 82 and the notch 6 cooperate with each other to fix the connecting rod 14. When the connecting rod 14 is removed, the rotating block 7 is rotated in the reverse direction, and the spring 91 pushes the movable block 8 in the reverse direction to restore it to its initial position.

[0041] The working principle of the utility model is:

[0042] The worker sits at the riveting machine 2 and is responsible for removing the connecting rod 14 from the conveying block 12 on the conveyor belt 11 with his right hand.

[0043] The right hand passes the middle part of the connecting rod 14 through the notch 6 at the upper groove 52 from top to bottom. When the connecting rod 14 moves to the middle of the upper groove 52, the person releases the connecting rod 14 by hand. Under the factor of gravity, the connecting rod 14 automatically falls, so that the larger part above the connecting rod 14 will be located in the upper groove 52, and the connecting rod 14 will not fall down without human support.

[0044] Then, hold the handle 71 with your left hand and rotate the rotating block 7 to the right, so that the rotating block 7 rotates eccentrically based on the inner pin shaft 41 seat, and then the larger part of the body of the rotating block 7 on the other side will be embedded in the groove 81. Since the rotating block 7 is embedded in the groove 81, it will resist the movable block 8 and move along the slide rail 9 toward the notch 6 through the slider below. At the same time, the spring 91 in the slide rail 9 is deformed and compressed to generate elastic force. When the fixed port 82 is completely embedded in the notch 6, the connecting rod 14 is effectively fixed through the mutual cooperation of the fixed port 82 and the notch 6. Then the drill rig 21 drives the drill bit to descend and tighten the nut. After the processing is completed, rotate the rotating block 7 in the opposite direction, and the rotating block 7 and the groove 81 are separated. Then, under the action of the elastic force of the spring 91, it moves in the opposite direction along the slide rail 9. Then, remove the processed connecting rod 14, and put the unprocessed connecting rod 14 in the right hand again.
