Description

Technical Field

[0001] The present invention relates to the technical field of motorcycle parts production, and specifically relates to a bolt pressing-in device for motorcycle shock absorbers. Background Technique

[0002] The motorcycle shock absorber is a crucial component on a motorcycle. Its main function is to absorb and attenuate the shocks and vibrations caused by uneven road surfaces during the motorcycle's travel. This can ensure the comfort of riding, improve the stability and handling of the vehicle, and extend the service life of the vehicle.

[0003] A bolt needs to be pressed into the bottom of the piston rod in the shock absorber for subsequent assembly of accessories. In the prior art, whether it is a hydraulic drive type, pneumatic impact type, or servo press-fit type bolt pressing-in device, there is generally a long-standing technical problem that has not been solved. The bolt rod body is generally manually loaded by operators, which easily leads to tilting. Moreover, before processing, foreign matters such as debris are likely to remain on the inner wall of the connecting hole of the piston rod, which will also cause tilting during the pressing-in process, affecting the accuracy of subsequent installation and the processing quality. Therefore, we propose a bolt pressing-in device for motorcycle shock absorbers to solve the above problems. Summary of the Invention

Detailed implementation manner

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-8 , the present invention provides a technical solution: a bolt pressing-in device for a motorcycle shock absorber, including

[0038] An operating table 1, on the top of which there is a transmission seat 2 for limiting and transmitting the piston rod. A pair of limit seats 4 are installed at the rear end of the transmission seat 2. There is a top plate on the top of the operating table 1, and a stamping head 5 and a transfer claw 6 are provided at the bottom of the top plate. The two limit seats 4 correspond to the stamping head 5 and the transfer claw 6 respectively;

[0039] Among them, a positioning frame 3 is provided at the upper end of the transmission base 2. The positioning frame 3 is movably clamped at the bottom of the top plate. A positioning ring 36 is provided at the bottom of the positioning frame 3. A rotating disk 21 is rotatably provided on the top of the transmission base 2. A plurality of limit sliders 26 are clamped on the rotating disk 21. The cooperation between the positioning ring 36 and the limit sliders 26 can position and calibrate the piston rod. When the bolt needs to be pressed in, the piston rod can be clamped inside the limit sliders 26, and the position of the positioning slider 31 is adjusted to limit according to different models of piston rods. With the positioning ring 36 and a plurality of cleaning plates 371 at the bottom against the inner part of the clamping groove at the top of the piston rod, it is used for auxiliary correction to reduce the situation of deviation and inclination during clamping. During the feeding process of the cleaning plates 371, the inside of the clamping groove can be cleaned to reduce the influence of residual debris and foreign objects inside on the subsequent bolt pressing process. And the operator can manually insert the bolt rod into the clamping groove and can observe with the positioning ring 36 at the upper end to reduce the situation of inclination and deviation. And as the transmission base 2 rotates, the stamping head 5 can press the bolt shaft in. And after the processing is completed, the transfer claw 6 can disassemble and transport the piston rod.

[0040] As Figure 6 shown, a positioning slider 31 is movably clamped at the bottom of the positioning frame 3. A piston assembly 32 is installed at the bottom of the positioning slider 31 and a connecting pipe 33 is installed at the bottom end of the piston assembly 32. Driving shafts are installed at both ends of the connecting pipe 33, and the driving shafts are installed at the bottom of the positioning slider 31;

[0041] A telescopic rod 34 is installed inside the connecting pipe 33. A screw rod 341 is installed at the bottom of the telescopic rod 34. The positioning ring 36 is threadedly sleeved outside the screw rod 341. A rotating ring 361 is rotatably provided at the top of the positioning ring 36. A pair of reset insertion rods inserted into the telescopic rod 34 are installed on the rotating ring 361 for pushing the positioning ring 36 to reset. The positioning ring can be against the top of the piston rod during the clamping and positioning process to keep it in a vertical state and can clamp its bottom on the limit sliders 26.

[0042] As Figure 7 and Figure 8 shown, in order to reduce the situation of debris residue in the clamping groove of the piston rod, a plurality of movable plates 37 are installed at the bottom of the positioning ring 36. The positions of the movable plates 37 can be adjusted. A plurality of reset shafts 38 are inserted into the movable plates 37. A cleaning plate 371 is installed at one end of the reset shaft 38. The other end of the reset shaft 38 is located outside the screw rod 341. A driving ring is clamped on the outer wall of the screw rod 341, and the driving ring follows the screw rod 341 to squeeze with the reset shaft 38;

[0043] A cleaning plate 371 is installed outside the reset shaft 38 on one side of the movable plate 37. The cleaning plate 371 is in a "U" shape. A nylon mesh plate is provided on the outer wall of the cleaning plate 371. The bottom of the cleaning plate 371 is in an arc shape and has elasticity, and an air pressure tube 372 is clamped inside. A plurality of plastic sheets are provided on the air pressure tube 372 and are used to abut against the inside of the cleaning plate 371. As the screw rod 341 feeds, the positioning ring 36 can rotate when it fits on the top of the piston rod. At this time, under the limiting action of the bottom limiting slider 26, the piston rod will not move. After the piston rod is calibrated and clamped, the cleaning plate 371 is used to clean the inside of the clamping groove. The driving ring can interact with the reset shaft 38, drive the cleaning plate 371 to expand outwards, and cooperate with the circumferential movement of the cleaning plate 371 to further clean the inside of the clamping groove, playing a cleaning role, and clamping the debris in the nylon mesh plate and taking it out.

[0044] As Figure 6 shown, in order to reduce the maintenance and cleaning time of the operator, a clamping ring 35 is clamped on the outer wall of the connecting pipe 33. A transmission hole is opened on the clamping ring 35. A one-way air inlet hole and a one-way air outlet hole are respectively opened on the outer wall of the piston assembly 32, and the one-way air inlet hole is connected to the transmission hole by means of a rubber tube;

[0045] A plurality of air extraction holes are opened inside the clamping ring 35, and the air extraction holes are connected to the transmission holes. An adsorption ring 351 is installed inside the clamping ring 35. The adsorption ring 351 is made of sponge material and corresponds to the air extraction holes. The adsorption ring 351 can be clamped outside the positioning ring 36. When the driving rod moves, the connecting pipe 33 can be moved to a suitable position, and at this time the piston assembly 32 is in a state of air extraction, enabling the air flow to enter along the adsorption ring 351. Under the negative pressure action, the surface of the cleaning plate 371 located inside the clamping ring 35 at this time can be subjected to air extraction and dust collection treatment, quickly recovering and adsorbing the debris remaining on its surface, having a self-cleaning effect.

[0046] As Figure 5 shown, in order to ensure the stability of clamping, the limiting slider 26 is in an "L" shape. A pair of movable insertion plates 28 are inserted on the limiting slider 26. A fixing plate spring-connected to the limiting slider 26 is installed at the rear end of the pair of movable insertion plates 28, and a reset pressing block 27 is installed at its front end. A pair of arc-shaped plates are installed at the rear end of the reset pressing block 27, and a pair of sliding rods are slidably arranged between the arc-shaped plates. An arc-shaped groove is opened on the limiting slider 26. The reset pressing block 27 is arranged inside the arc-shaped groove, and a covering piece 272 is installed between the two ends of the arc-shaped groove and the sliding rod to enhance the frictional force of the limit. After the reset pressing block 27 moves, the sliding rod moves to both ends of the arc groove and fits on the outer wall of the piston rod under its own elasticity, which can increase the frictional force during the clamping process and ensure the stability of clamping;

[0047] The reset block 27 is arc-shaped and has a friction pad 271 installed inside. A plurality of stop shafts are installed on the friction pad 271. The stop shafts can fit on the outer wall of the bottom of the piston rod under the elastic action of the friction pad 271 for auxiliary clamping.

[0048] like Figure 5 An arc-shaped pressure plate 29 is movably provided on the limit slider 26, and a plurality of support rings 291 are fixedly connected to the arc-shaped pressure plate 29. The arc-shaped pressure plate 29 and the limit slider 26 form a clamping component. The support ring 291 can play a role in assisting feeding during the clamping process. The operator can push the bottom of the piston rod along the curvature of the support ring 291 to between the arc-shaped pressure plate 29 and the reset block 27.

[0049] like Figure 4 As shown, in order to ensure the stability of packaging limit, a fixed shaft is installed on the top of the rotating disk 21, and a transmission disk 22 is inserted on the fixed shaft, a plurality of adjustment shafts 25 are installed on the top of the transmission disk 22, and a connecting ring 24 is installed on the top of the fixed shaft, and the adjusting shaft 25 is inserted in the circular groove at the bottom of the connecting ring 24;

[0050] There are multiple notches on the edge of the transmission disk 22, and a clamping plate 23 is installed inside the notch. Multiple limit pressure plates 231 are installed inside the clamping plate 23. The position of the limit pressure plate 231 corresponds to the limit slider 26. The middle section of the piston rod can be clamped between the limit pressure plates 231 for auxiliary support to reduce the tilt and deviation during the loading process.

[0051] like Figure 3 As shown, a lifting plate 41 is movably provided on the limit seat 4, a fixed cylinder 42 is installed at the rear end of the lifting plate 41, and a blocking plate 43 is installed on the output end of the fixed cylinder 42. The blocking plate 43 can be used to support one end of the piston rod, thereby reducing the force deviation of the piston rod during the subsequent punching process.

[0052] Preferably, a docking groove is provided at the bottom of the punch head 5, and a punching accessory is installed inside the docking groove, which can be replaced according to different types of bolt accessories.

[0053] like Figure 2 As shown, the transfer claw 6 is movably clamped at the bottom of the top and is used to disassemble the processed piston rod, which can improve the overall processing efficiency.

[0054] Working principle: Firstly, when the bolt needs to be pressed in, the piston rod can be clamped inside the limit slider 26, and the position of the positioning slider 31 can be adjusted to limit according to piston rods of different models. By means of the positioning ring 36 and multiple cleaning plates 371 at the bottom against the internal card slot at the top of the piston rod, it is used for auxiliary correction to reduce the situation of deviation and inclination during clamping. During the feeding process of the cleaning plate 371, the inside of the card slot can be cleaned to reduce the influence of residual debris and foreign objects inside on the subsequent bolt pressing process. And the operator can manually insert the bolt rod into the card slot and can observe with the help of the positioning ring 36 at the upper end to reduce the situation of inclination and deviation. Along with the rotation of the transfer seat 2, the punching head 5 can press the bolt shaft. After the processing is completed, the transfer claw 6 can disassemble and transport the piston rod. And during the limitation of the piston rod body, the bottom of the piston rod can be clamped between the reset pressing block 27 and the arc-shaped pressing plate 29. When positioning is required, the positioning ring 36 can be against the top of the piston rod card slot to keep the piston rod in a vertical state. And during the limitation process, the piston rod can be in contact with the coating piece 272 and the friction backing plate 271 respectively, and both can fit on the outer wall of the piston rod under their own elastic action, which can increase the friction force during the clamping process;

[0055] Then, continue to adjust the position of the positioning slider 31 and cooperate with the movement of the driving rod to move the connecting pipe 33 to a suitable position. At this time, the piston assembly 32 is in the state of air extraction, and the air flow can enter along the adsorption ring 351. Under the negative pressure effect, the surface of the cleaning plate 371 located inside the clamping ring 35 can be subjected to air extraction and dust collection treatment, and the residual debris on its surface can be quickly recycled and adsorbed, having a self-cleaning effect. Along with the feeding of the screw rod 341, the positioning ring 36 can rotate when it fits on the top of the piston rod. At this time, under the limiting action of the bottom limit slider 26, the piston rod will not move. After the piston rod is calibrated and clamped, the inside of the card slot can be cleaned in cooperation with the cleaning plate 371. The driving ring and the reset shaft 38 can interact with each other to drive the cleaning plate 371 to expand outwards, and cooperate with the circular motion of the cleaning plate 371 to further clean the inside of the card slot;

[0056] Finally, after the calibration and cleaning are completed, insert the piston rod into the card slot. At this time, the cleaning plate 371 can move into the clamping ring 35 along with the telescopic rod 34. And the driving shaft drives the connecting pipe 33 to move, and the bottom of the movable plate 37 can be against the top of the bolt for auxiliary correction. Subsequently, it can be combined with the group punching head 5 for punching and installation. The transfer claw 6 can clamp and pull out the processed piston rod outwards, making the arc-shaped pressing plate 29 move outwards to reduce the friction force at the bottom of the piston rod and can disassemble it and transfer it to the packing box.
