Cutting equipment for processing automobile shock absorber outer tube

Abstract

This invention relates to the field of pipe cutting technology, and in particular to a cutting device for processing automotive shock absorber outer tubes. The device includes a feeding unit, a clamping unit mounted on the feeding unit, a negative pressure unit mounted on the clamping unit, and a cutting unit mounted on the feeding unit. The invention uses a connecting sleeve to drive the upper and lower clamping components to abut against each other, initially clamping the outer surface of the pipe to prevent excessive clamping force from causing pipe deformation. The cutting gap, combined with the cutting tool, ensures the overall stability of the pipe during shearing. Simultaneously, when the connecting sleeve drives the clamping assembly to clamp the pipe, the toothed plate 1 drives the toothed plate 2 through gears, causing the piston to move within the movable cavity, generating negative pressure in the inner cavity. This, combined with the contact pad, firmly holds both sides of the cutting gap, further fixing the position of the pipe and preventing the pipe from loosening during cutting, thus improving cutting accuracy.

Description

Technical Field

[0001] This invention relates to the field of pipe cutting technology, and in particular to a cutting device for processing the outer tube of an automobile shock absorber. Background Technology

[0002] The outer tube of a car shock absorber usually refers to the outermost part of the shock absorber cylinder. It is a key component in the shock absorber structure and one of the main load-bearing parts of the shock absorber, bearing the vertical load from the vehicle body. The outer tube usually contains the inner tube. The outer tube works with components such as oil seals and guides to prevent hydraulic oil leakage and to prevent external contaminants such as dust and moisture from entering.

[0003] During vehicle debugging and repair, the length of the shock absorber sometimes needs to be adjusted. This requires cutting the outer tube of the shock absorber. The outer tube of automotive shock absorbers is mostly a thin-walled steel tube. During cutting, the steel tube is usually fixed by a clamping mechanism and then cut by a cutting tool. However, the outer tube is a typical thin-walled part. If the clamping force of the three-jaw or internal support chuck is slightly too large, the tube will be deformed. After being released, it will elastically rebound, resulting in out-of-tolerance roundness and cylindricity. If the clamping force is reduced, the workpiece is prone to loosening and shifting during cutting, resulting in unstable axial dimensions. Summary of the Invention

[0004] In view of the problems in the above or existing technologies, where the pipe is deformed by a slightly large clamping force of the three-jaw or internal support chuck, and then springs back elastically after being released, resulting in out-of-tolerance roundness and cylindricity; and that if the clamping force is reduced, the workpiece is prone to loosening and shifting during cutting, resulting in unstable axial dimensions, this invention is proposed.

[0010] As a preferred embodiment of the cutting equipment for processing the outer tube of the automobile shock absorber of the present invention, the upper clamping member includes an arc-shaped clamping claw disposed on the negative pressure unit, a contact pad disposed on the arc-shaped clamping claw, a connecting post disposed on the arc-shaped clamping claw, a protrusion disposed on the connecting post, and an inner cavity disposed on the side of the arc-shaped clamping claw near the tube.

[0011] As a preferred embodiment of the cutting equipment for processing the outer tube of the automobile shock absorber of the present invention, wherein: in the clamping state, the arc-shaped claws on the upper clamping member and the lower clamping member are connected.

[0012] As a preferred embodiment of the cutting equipment for processing the outer tube of the automobile shock absorber of the present invention, the support plate is provided with an opening, and the tube passes through the opening in the clamping state.

[0013] As a preferred embodiment of the cutting equipment for processing the outer tube of the automobile shock absorber of the present invention, the negative pressure linkage component includes a toothed plate 1 disposed on the connecting sleeve, a gear disposed on the connecting column and meshing with the toothed plate 1, and a linkage component disposed on the connecting column.

[0014] As a preferred embodiment of the cutting equipment for processing the outer tube of the automobile shock absorber of the present invention, the linkage includes a second toothed plate disposed on the connecting column and meshing with a gear, a piston disposed on the second toothed plate, a movable cavity disposed on the connecting column and cooperating with the piston, and a return spring disposed in the movable cavity; a through hole is provided at the bottom of the movable cavity, and the through hole communicates with the inner cavity.

[0016] The beneficial effects of the cutting equipment for processing automotive shock absorber outer tubes of the present invention are as follows: The present invention uses a connecting sleeve to drive the upper and lower clamping parts to abut against each other, initially clamping the outer part of the tube to prevent excessive clamping force from causing tube deformation. The cutting gap, combined with the cutting tool, ensures the overall stability of the tube during shearing. Simultaneously, when the connecting sleeve drives the clamping assembly to clamp the tube, the toothed plate 1 drives the toothed plate 2 through gears, causing the piston to move in the movable cavity, forming an annular negative pressure zone on both sides of the cutting position. This draws the outer tube wall into the inner cavity of the clamping claws, preventing clamping deformation and counteracting axial movement during cutting. This is particularly suitable for the prototype vehicle suspension tuning stage, allowing for rapid cutting of the shock absorber outer tube from the standard length to a customized length matching the vehicle's posture. It ensures the roundness of the cut end meets requirements, allowing for direct press-fitting of the oil seal without secondary shaping, shortening the trial production cycle. For shock absorbers that have already been assembled and are being repaired, the outer tube can be precisely cut directly without disassembling the internal valve system, avoiding complete scrapping.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Example 1, referring to Figure 1 - Figure 9This is the first embodiment of the present invention. This embodiment provides a cutting device for processing the outer tube of an automobile shock absorber. It includes a feeding unit 1, a clamping unit 2 disposed on the feeding unit 1, a negative pressure unit 3 disposed on the clamping unit 2, and a cutting unit 4 disposed on the feeding unit 1. The feeding unit 1 is used to convey the tube 6, the clamping unit 2 is used to clamp and fix the tube 6, the negative pressure unit 3 drives the clamping unit 2 to further fix and clamp the two sides of the part to be cut on the tube 6 to prevent the tube 6 from loosening and deforming, so that the tube 6 remains stable when being cut, and the cutting unit 4 is used to cut the part of the tube 6 clamped by the clamping unit 2 driven by the negative pressure unit 3. The clamping unit 2 includes a clamping component 21 disposed on the feeding unit 1, a support plate 22 disposed on the feeding unit 1, and a clamping component 23 disposed on the support plate 22 and cooperating with the clamping component 21. The clamping component 21 and the clamping component 23 are used to initially fix and clamp the two sides of the cut part on the pipe 6 to prevent the pipe 6 from deforming due to excessive clamping force. The support plate 22 is used to provide support for the clamping component 23. The negative pressure unit 3 includes an electric push rod 31 mounted on the feeding unit 1 and the support plate 22, a connecting sleeve 32 mounted on the output end of the electric push rod 31 and cooperating with clamping components 21 and 23, a connecting spring 33 mounted on the connecting sleeve 32, and a negative pressure linkage component 34 mounted on the connecting sleeve 32. The electric push rod 31 drives the connecting sleeve 32 to move up and down, thereby driving the clamping components 21 and 23 to fix and clamp the pipe 6. The connecting sleeve 32 is detachably connected to the output end of the electric push rod 31. Specific structures can be found in existing technologies and will not be elaborated upon here. Through this configuration, by controlling the connecting sleeve 3... 2. Replacement is performed to replace the clamping unit 2 with different models to adapt to different sizes of pipe 6. The connecting spring 33 plays a connecting role, so that the connecting sleeve 32 maintains support on the clamping component 1 21 and clamping component 23. The negative pressure linkage component 34 is used to cooperate with the connecting sleeve 32 to drive the relative movement of clamping component 1 21 and clamping component 23 when clamping pipe 6, so that negative pressure is generated at the clamping part of clamping component 1 21 and clamping component 23 to firmly suck up pipe 6 and prevent pipe 6 from loosening during cutting. At the same time, it maintains support on both sides of pipe 6 that are being cut, so as to prevent the cutting unit 4 from squeezing and deforming pipe 6 when cutting pipe 6, which would cause errors in cutting accuracy.

[0031] In summary, when it was discovered during the rear suspension tuning of the prototype vehicle that the battery pack was raised, causing the shock absorbers to need to be shortened to avoid tire bounce interference, the operator transported the welded bottom cover and unsealed shock absorber tube 6 to be reworked via the feeding unit 1 to the clamping assembly 21. At this time, the electric push rod 31 was activated, and the electric push rod 31, through the connecting sleeve 32, drove the clamping assembly 21 and the clamping assembly 23 to initially fix and clamp the two sides of the tube 6 at the cutting point. The movement of clamping components 21 and 23 relative to the pipe 6 causes a negative pressure to be generated on the side of clamping components 21 and 23 that are in contact with the pipe 6, firmly holding the pipe 6 and preventing it from loosening. At the same time, it provides outward support to both sides of the pipe 6 to be cut, preventing the cutting action of the cutting unit 4 from causing compression deformation of the pipe 6. At this time, the cutting unit 4 is started to cut the area to be cut formed by clamping components 21 and 23 holding the pipe 6.

[0032] Example 2, refer to Figure 1 - Figure 9 This is the second embodiment of the present invention. Unlike the previous embodiment, it provides the specific structure of the feeding unit 1 and clamping unit 2 in a cutting device for processing automotive shock absorber outer tubes. Compared to embodiment 1, the feeding unit 1 further includes a device housing 11, an inlet 12 disposed on the device housing 11, a feeding assembly 13 disposed on the device housing 11, and an outlet 14 disposed on the feeding unit 1. The two ends of the feeding assembly 13 are respectively connected to the inlet 12 and the outlet 14. The device housing 11 serves to support the entire device. The inlet 12 is used to feed the tube 6 into the feeding assembly 13, which in turn conveys the tube 6. The outlet 14 is used to feed the tube 6 conveyed by the feeding assembly 13 into the clamping unit 2.

[0033] The feeding assembly 13 includes a support base 131 mounted on the equipment housing 11, an electric feeding wheel 132 mounted on the support base 131, and a first support screw 133 and a second support screw 134 mounted on the support base 131. The support base 131 serves as a connector, the electric feeding wheel 132 contacts the pipe 6 and rotates to transport the pipe 6, and the first support screw 133 and the second support screw 134 are driven by a motor. By rotating, they cause the support base 131 to move closer or further apart to accommodate pipes 6 of different sizes.

[0034] The clamping assembly 21 includes an upper clamping member 211 and a lower clamping member 212 disposed around the discharge port 14. The upper clamping member 211 and the lower clamping member 212 have the same structure. In the clamping state, the ends of the upper clamping member 211 and the lower clamping member 212 are connected. With this arrangement, the upper clamping member 211 and the lower clamping member 212 can initially clamp the pipe 6. At the same time, due to the abutment of the upper clamping member 211 and the lower clamping member 212, the clamping force is prevented from being too strong and causing the pipe 6 to deform. Clamping component 23 has the same structure as clamping component 21. In the clamping state, the distance between clamping component 21 and clamping component 23 is set as the cutting gap 5. With this setting, clamping component 21 and clamping component 23 clamp both sides of the cutting gap 5, so that the cut of the pipe 6 remains stable during the cutting process.

[0035] The upper clamping component 211 includes an arc-shaped clamping claw 2111 disposed on the negative pressure unit 3, a contact pad 2112 disposed on the arc-shaped clamping claw 2111, a connecting post 2113 disposed on the arc-shaped clamping claw 2111, a protrusion 2114 disposed on the connecting post 2113, and an inner cavity 2115 disposed on the side of the arc-shaped clamping claw 2111 near the pipe 6. The arc-shaped clamping claw 2111 is used to clamp the pipe 6, the contact pad 2112 is used to contact the outer wall of the pipe 6 and fit tightly with the arc-shaped clamping claw 2111, the connecting post 2113 is used to drive the arc-shaped clamping claw 2111 to move in conjunction with the connecting sleeve 32, the protrusion 2114 is used to abut against one end of the connecting spring 33, and the inner cavity 2115 is used to abut against the pipe 6 with the contact pad 2112 to form a closed space.

[0036] In the clamping state, the arc-shaped claws 2111 on the upper clamping member 211 and the lower clamping member 212 are connected. Through this setting, the inner cavity 2115 forms an annular sealed space surrounding the outer diameter of the pipe 6. With the movement of the connecting sleeve 32, a negative pressure is formed in the annular sealed space, which firmly sucks the outer wall of the pipe 6, forming a secondary fixation, so that the clamped part of the pipe 6 is subjected to balanced force, and the pipe 6 is prevented from loosening during cutting.

[0037] The support plate 22 has an opening 221. When clamped, the pipe 6 passes through the opening 221. The opening 221 is used for the pipe 6 to pass through, which facilitates the clamping component 1 21 and the clamping component 23 to clamp and fix both sides of the cutting gap 5.

[0038] The rest of the structure is the same as in Example 1.

[0039] In summary, if a batch of oil-filled shock absorbers is found to have a pipe length 6 that is longer than the design value on the assembly line, the pipe 6 is fed into the feeding assembly 13 through the inlet 12. Through the conveying of the feeding assembly 13, the pipe 6 enters from the outlet 14 between the clamping assembly 1 21 and the clamping assembly 23, and passes through the opening 221. When the pipe 6 is output to the specified length, the electric push rod 1 31 is activated. With the support of the connecting sleeve 32 and the connecting spring 33, the upper clamping member 211 and the lower clamping member 212 initially clamp the two sides of the cutting gap 5. At this time, the contact pad 2112 contacts and abuts against the outer wall of the pipe 6. The connecting sleeve 32 continues to move. Through the action of the connecting spring 33 and the negative pressure linkage assembly 34, a negative pressure is generated in the inner cavity 2115, which firmly sucks the outer wall of the pipe 6, forming a secondary fixation, so that the clamped part of the pipe 6 is subjected to balanced force, preventing the pipe 6 from loosening during cutting.

[0040] Example 3, referring to Figure 1 - Figure 10 This is the second embodiment of the present invention. Unlike the previous embodiment, it provides the specific structure of the negative pressure linkage assembly 34 and the cutting unit 4 in the cutting equipment for processing automotive shock absorber outer tubes. Compared to embodiment 2, the negative pressure linkage assembly 34 further includes a toothed plate 341 disposed on the connecting sleeve 32, a gear 342 disposed on the connecting post 2113 and meshing with the toothed plate 341, and a linkage member 343 disposed on the connecting post 2113. The toothed plate 341 is used to cooperate with the connecting sleeve 32 to move up and down relative to the connecting post 2113. The gear 342 is used to cooperate with the movement of the toothed plate 341 to rotate. The linkage member 343 is used to cooperate with the rotation of the gear 342, so that when the arc-shaped chuck 2111 clamps the tube 6, negative pressure is generated in the inner cavity 2115.

[0041] The linkage 343 includes a toothed plate 3431 disposed on the connecting column 2113 and meshing with the gear 342, a piston 3432 disposed on the toothed plate 3431, a movable cavity 3433 disposed on the connecting column 2113 and cooperating with the piston 3432, and a return spring 3434 disposed in the movable cavity 3433. The toothed plate 3431 is used to move up and down in the movable cavity 3433 in coordination with the rotation of the gear 342. The piston 3432 is used to move in the movable cavity 3433 in coordination with the movement of the toothed plate 3431, thereby controlling the generation of negative pressure in the movable cavity 3433. The return spring 3434 is used to cooperate with the connecting spring 33 to keep the negative pressure linkage assembly 34 supported on the connecting column 2113. The bottom of the movable cavity 3433 is provided with a through hole 3435, which is connected to the inner cavity 2115. With this arrangement, the piston 3432 moves in the movable cavity 3433 to control the generation of negative pressure in the inner cavity 2115.

[0042] The cutting unit 4 includes a fixed base 41 disposed on the side of the equipment housing 11 near the discharge port 14, a cutting blade 42 disposed on the fixed base 41, and an electric push rod 43 disposed on the fixed base 41 and whose output end is fixedly connected to the cutting blade 42. The fixed base 41 serves as a support, the cutting blade 42 is used to cut the cutting gap 5, and the electric push rod 43 is used to drive the cutting blade 42 to move back and forth on the fixed base 41, thereby controlling the cutting blade 42 to approach the cutting gap 5 for cutting operations. The cutting tool 42 is provided with a limiting block 421, and the fixed base 41 is provided with a limiting groove 411 that cooperates with the limiting block 421. The limiting groove 411 and the limiting block 421 cooperate to limit the sliding trajectory of the cutting tool 42 on the fixed base 41. With the drive of the electric push rod 43, the cutting tool 42 moves back and forth stably on the fixed base 41.

[0043] The rest of the structure is the same as in Example 2.

[0044] In summary, when the electric push rod 31 is activated, it drives the upper clamping member 211 and the lower clamping member 212 to clamp both sides of the cutting gap 5 through the connecting sleeve 32. At this time, the contact pad 2112 contacts the outer wall of the pipe 6, and the inner cavities 2115 on the upper clamping member 211 and the lower clamping member 212 are connected and aligned. The connecting sleeve 32 continues to move, and the connecting spring 33 is stretched. At this time, the toothed plate 341 drives the gear 342 to rotate, and the gear 342 drives the toothed plate 3431 to move. The toothed plate 3431 drives the piston 3432 to slide in the movable cavity 3433. At this time, the space between the movable cavity 3433 and the inner cavity 2115 increases, and the return spring 3434 is stretched. A negative pressure is generated in the inner cavity 2115, which clamps the portion between the pipe 6 and the inner cavity 2115. The tube is firmly held in place. At this point, the electric push rod 43 activates, driving the cutting tool 42 closer to the cutting gap 5 and cutting it. After cutting, the electric push rod 31 drives the connecting sleeve 32 back to its original position. The electric push rod 31 then moves the connecting sleeve 32 relative to the connecting post 2113. The connecting spring 33 returns to its original position, and the connecting sleeve 32, through the gear 342, drives the toothed plate 3431 to move, causing the piston 3432 to slide towards the through hole 3435, restoring the pressure inside the inner cavity 2115 to normal. The connecting sleeve 32, through the connecting spring 33, drives the arc-shaped claw 2111 to leave the tube 6. The tube 6 can then be directly transferred to the online roundness inspection station. The entire cutting and releasing cycle is short, meeting the small-batch, high-frequency, and rapid iteration debugging rhythm of the prototype stage. For different suspension height versions of the same model, only the corresponding length parameters need to be adjusted; the equipment automatically adjusts the feeding stroke and cutting depth, achieving one-click type change without the need to replace any fixtures.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
