Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing, and specifically relates to an intelligent processing device for a shock absorber piston cylinder. Background Art

[0002] A shock absorber is an important component in an automobile suspension system, and its main function is to suppress the oscillation when the shock-absorbing spring rebounds after absorbing shock and the impact from the road surface. At present, in the manufacture of the middle cylinder of a shock absorber, a steel pipe with a relatively large length needs to be cut into the length required for the cylinder. In the process of small-batch production, it is mostly achieved by means of a cutting machine. Burrs will be generated during the cutting process and need to be removed by subsequent processing, resulting in low efficiency.

[0003] In view of the above problems, Chinese Patent 202210416120.4 discloses a cutting and positioning device for a shock absorber cylinder, including a workbench, a guide seat, a positioning component, a cutting component, and a burr removal component. The present invention can not only realize the positioning cutting of the steel pipe for the shock absorber cylinder, but also synchronously remove the burrs on the surface of the cut steel pipe by means of the retraction action of the cutting component after cutting, simplifying the processing equipment and process, and reducing the product transfer time between different processes. The designed burr removal mechanism that can be unfolded and closed in the present invention does not contact the steel pipe during the feeding and discharging of the steel pipe, and only moves horizontally near the cutting surface to remove burrs, which can reduce the damage caused by the burr removal mechanism to the non-cutting surface of the steel pipe, and the floating blowing mechanism can realize blowing the burrs attached to the pipe wall into the material box while the burr removal mechanism removes burrs.

[0004] However, when the above device is in use, its grinding component adopts a one-way plane contact removal method, which can only effectively process the radial burrs on the outer edge of the cutting end face, and the annular inner peripheral burrs generated due to metal plastic deformation during the cutting process cannot be removed. Such inner wall defects will cause the piston rod to get stuck during reciprocating motion, accelerate the wear of the seal, and the remaining burrs are prone to form stress concentration points in the subsequent heat treatment process, reducing the fatigue life of the cylinder. Therefore, we propose an intelligent processing device for a shock absorber piston cylinder. Summary of the Invention

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1: Please refer to Figures 1 - 12 , the present invention provides a technical solution: an intelligent processing device for a shock absorber piston cylinder, including a workbench 1, and further including a fixed seat 2 fixedly arranged on the workbench 1. A through hole for the steel pipe to pass through is provided on the fixed seat 2. A steel pipe automatic conveying mechanism can be arranged at the rear side of the fixed seat 2 for automatically feeding the steel pipe after cutting. The steel pipe automatic conveying mechanism is a prior art and will not be elaborated herein:

[0039] It further includes a clamping assembly 3 movably arranged on the workbench 1. The clamping assembly 3 can clamp the steel pipe before cutting to keep the steel pipe stable during cutting, and can also drive the cut steel pipe to move, so as to leave a distance from the main material for grinding. An installation block 8 is fixedly arranged on the workbench 1, and a cutting assembly 4 is also arranged, which includes a support frame 41 slidably arranged on the installation block 8. A motor and a cutting tool 42 driven by the motor are arranged on the support frame 41. The driving of the cutting tool 42 to rotate by the motor is a prior art and will not be elaborated herein. A driving cylinder 43 is fixedly arranged on the installation block 8, and the output end of the driving cylinder 43 is connected to the support frame 41. When the driving cylinder 43 extends, it can drive the cutting tool 42 to move through the support frame 41 to cut the steel pipe;

[0040] A grinding assembly 5 is arranged on the other side of the workbench 1 relative to the cutting assembly 4. After the steel pipe is cut, the grinding assembly 5 can move to the cutting surface to grind the cutting end face and the inner peripheral edge of the pipe.

[0041] The clamping assembly 3 includes a clamping cylinder 31 slidably arranged on the workbench 1. The clamping cylinder 31 is slidably arranged along the conveying direction of the steel pipe. Both sides of the clamping cylinder 31 are fixedly connected with ear plates 32. A guide rod 33 and a lead screw 34 are respectively arranged on the two ear plates 32. The guide rod 33 slidably penetrates through the ear plate 32. A motor is arranged on the workbench 1, and the output end of the motor is connected to the lead screw 34. The lead screw 34 threadedly penetrates through the ear plate 32. A fixed block 35 is arranged on the clamping cylinder 31, and a moving block 36 is arranged at the output end of the clamping cylinder 31. Notches for fixing the steel pipe are respectively arranged on the moving block 36 and the fixed block 35;

[0042] The clamping cylinder 31 can drive the moving block 36 to move. When the clamping cylinder 31 extends, it drives the moving block 36 to move upward away from the fixed block 35, and then no longer clamps the steel pipe. At this time, the cut steel pipe can be unloaded. When the clamping cylinder 31 contracts, it drives the moving block 36 to fit with the fixed block 35. At this time, the steel pipe can be clamped. The motor drives the lead screw 34 to rotate, which can drive the clamping cylinder 31 to move, and then drive the cut steel pipe to move, so that the cut section of the steel pipe moves relative to the main material, leaving a space for the grinding assembly 5 to insert.

[0043] A chute 9 is provided on the workbench 1. A slider 10 is slidably arranged in the chute 9. Support springs 11 are arranged on both sides of the slider 10. The two ends of the support springs 11 are respectively connected to the slider 10 and the side wall of the chute 9. A slide plate 12 is slidably arranged on the workbench 1. The slide plate 12 is fixedly connected to the slider 10. The slide plate 12 can slide on the workbench 1. A box body 13 is movably arranged on the slide plate 12. Thus, the box body 13 can slide on the workbench 1 along with the slide plate 12. The grinding assembly 5 is arranged in the box body 13.

[0044] An elastic telescopic rod 14 is fixedly arranged on the slide plate 12. The end of the elastic telescopic rod 14 is connected to the box body 13. A connecting rod 15 is fixedly arranged on the support frame 41. A magnetic block 16 is fixedly arranged at the end of the connecting rod 15. An electromagnet is fixedly arranged on the box body 13. When the electromagnet is energized, it attracts the magnetic block 16;

[0045] When cutting, the driving cylinder 43 drives the support frame 41 to move, and then drives the cutting tool 42 to move to cut the steel pipe. At the same time, the movement of the support frame 41 will drive the magnetic block 16 to move through the connecting rod 15. When the cutting tool 42 completely cuts off the steel pipe, at this time, the magnetic block 16 fits with the electromagnet on the box body 13, and at the same time, the electromagnet is energized to attract the magnetic block 16. Thus, when the driving cylinder 43 drives the cutting tool 42 to reset, through the cooperation of the magnetic block 16 and the electromagnet, the box body 13 can be pulled to move, and then drive the grinding assembly 5 on the box body 13 to move to the cutting surface. In order to avoid the grinding assembly 5 from hitting the steel pipe, after the steel pipe is cut off, the clamping cylinder 31 moves to drive the cut steel pipe away from the main material, and then the cutting head retracts the tool to drive the box body 13 to move.

[0046] The grinding assembly 5 includes a driving gear 51 rotatably arranged inside the box body 13, a rack 52 fixedly arranged on the sliding plate 12 and meshing with the driving gear 51, a transmission shaft 53 rotatably arranged inside the box body 13, a transmission gear 54 arranged on the outer side of the transmission shaft 53 and meshing with the driving gear 51, a flywheel 55 also arranged on the outer side of the transmission shaft 53, a synchronizing shaft 56 rotatably arranged inside the box body 13, the synchronizing shaft 56 being coaxially arranged with the transmission shaft 53, a connecting member 6 capable of being in transmission connection with the transmission shaft 53 arranged at the end of the synchronizing shaft 56, a bracket 57 fixedly arranged inside the box body 13, the bracket 57 extending to the outside of the box body 13, and a fixing cylinder 58 fixedly arranged on the bracket 57, grinding units 7 being arranged at both ends of the fixing cylinder 58, and the grinding units 7 being connected to the synchronizing shaft 56 through belt transmission;

[0047] When the box body 13 is driven by the cutting knife 42 to move, that is, when the grinding assembly 5 moves to the cutting surface, the driving gear 51 meshes with the rack 52 and then the driving gear 51 rotates. The driving gear 51 drives the flywheel 55 to rotate through the transmission gear 54. After the cutting knife 42 resets, at this time the driving gear 51 is disengaged from the rack 52. Under the inertial action of the flywheel 55, the flywheel 55 continues to rotate. Then the synchronizing shaft 56 and the transmission shaft 53 are connected through the connecting member 6, and then the grinding units 7 are driven to rotate through belt transmission for grinding.

[0048] A slide rail 17 is arranged on the sliding plate 12, the box body 13 is slidably arranged on the slide rail 17, and an avoidance groove for the rack 52 to pass through is opened at the bottom of the box body 13.

[0049] The connecting member 6 includes an insertion block 61 slidably arranged at the end of the synchronizing shaft 56. A connecting spring 62 is arranged at one end of the insertion block 61 located inside the synchronizing shaft 56. The end of the connecting spring 62 is connected to the inner side of the synchronizing shaft 56. An electromagnet is arranged inside the synchronizing shaft 56. One end of the insertion block 61 located inside the synchronizing shaft 56 is made of a magnetic material. When the electromagnet is energized, it can repel the insertion block 61. A jack 63 for inserting and mating with the insertion block 61 is opened at the end of the transmission shaft 53;

[0050] When the grinding unit 7 moves to the cutting surface, at this time the electromagnet is energized to repel the insertion block 61 so that it inserts into the jack 63, and then the transmission shaft 53 and the synchronizing shaft 56 can perform power transmission. At this time, the flywheel 55 rotates to drive the transmission shaft 53 to rotate and then drive the synchronizing shaft 56 to rotate. The synchronizing shaft 56 drives the grinding unit 7 to rotate and grind through belt transmission.

[0051] The grinding unit 7 includes a grinding cylinder 71 rotatably arranged on the outer side of the fixing cylinder 58. Belt pulleys are arranged on the outer sides of the grinding cylinder 71 and the synchronizing shaft 56. A belt is installed on the outer sides of the belt pulleys. The grinding cylinder 71 is connected to the synchronizing shaft 56 through belt transmission. Grinding blocks 72 are also arranged inside the grinding cylinder 72, and the grinding blocks 72 can grind the inner circumference of the cutting surface.

[0052] In summary, during use, first, the steel pipe is fixed by the clamping cylinder 31. Subsequently, the cutting tool 42 feeds to cut the steel pipe. After the cutting tool 42 completes the cutting, the clamping cylinder 31 drives the cut section to move backward to leave a space for the grinding assembly 5 to enter. Then, when the cutting tool 42 retracts, the box body 13 is driven to move by the magnetic block 16 and the electromagnet, thereby driving the flywheel 55 to rotate. When the cutting tool 42 is fully reset, at this time, the grinding assembly 5 is located at the cutting surface. Then, the electromagnet is energized to repel the plug 61 so that it is inserted into the jack 63, thereby enabling power transmission between the transmission shaft 53 and the synchronizing shaft 56. At this time, the flywheel 55 rotates to drive the transmission shaft 53 to rotate, which in turn drives the synchronizing shaft 56 to rotate. The synchronizing shaft 56 drives the grinding unit 7 to rotate through belt transmission. During grinding, the clamping cylinder 31 can drive the cut steel pipe to move so that the end face of the cut steel pipe contacts the grinding cylinder 71 for grinding, that is, the clamping cylinder 31 drives the steel pipe to move, and the steel pipe abuts against the grinding cylinder 71, thereby driving the box body 13 to slide so that the grinding cylinder 71 on the other side contacts the main material end face for grinding. During grinding, the grinding cylinder 71 grinds the cutting surface, and the grinding block 72 can extend into the steel pipe to grind the inner circumference of the cutting surface.

[0053] Embodiment 2: Please refer to Figure 13 , the main structure of Embodiment 2 is the same as that of Embodiment 1. The difference lies in that the grinding block 72 is movably arranged in the fixed cylinder 58, a gear ring 73 is fixedly arranged in the grinding cylinder 71, and a plurality of planetary gears 74 meshing with the gear ring 73 are rotatably arranged on the fixed cylinder 58. A central gear 75 is rotatably arranged in the middle of the plurality of planetary gears 74. The central gear 75 meshes with the planetary gears 74. A rotating shaft 76 is fixedly arranged in the middle of the central gear 75, and the grinding block 72 is fixedly arranged at the end of the rotating shaft 76;

[0054] When the grinding cylinder 71 rotates, it can drive the gear ring 73 to rotate, thereby driving the central gear 75 to rotate through the planetary gears 74. The central gear 75 drives the grinding block 72 to rotate and grind through the rotating shaft 76. And due to the arrangement of the planetary gears 74, the rotating direction of the grinding block 72 is opposite to that of the grinding cylinder 71, which can avoid the problem of vibration at the end of the steel pipe caused by the same-direction rotation during grinding, thereby resulting in poor grinding effect.

[0055] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
