Description

Technical Field

[0001] This utility model relates to the field of automotive gas spring technology, and in particular to an end treatment device for automotive gas spring tubing. Background Technology

[0002] A gas spring in an automobile is a spring that utilizes the elasticity of air by filling a retractable, sealed container with compressed air. It is commonly known as an airbag, airbag cylinder, or bellows cylinder. A gas spring in an automobile is made by filling a sealed container with compressed air, utilizing the compressibility of gas to achieve its elastic effect.

[0003] Before use, the tubing used in the production of automotive gas springs needs to have its inner ring edge deburred. The conventional operation usually involves workers using a handheld deburring machine to grind the burrs off the tube openings. This prolonged operation can easily lead to worker fatigue and significantly affect processing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the deficiencies of the prior art by providing an end-processing device for automotive gas spring tubing, thereby solving the problems mentioned in the background art.

[0005] An end-processing device for automotive gas spring tubing includes a main worktable and a secondary worktable fixedly connected to each other, a pushing assembly for conveying tubing, a pressure application assembly for limiting tubing positioning, a deburring mechanism for processing tubing, and an ejection assembly for ejecting tubing. The pushing assembly is supported by the main worktable and the secondary worktable and includes a placement platform, a pusher frame, an electric cylinder three, and a fixing rod two. The placement platform is inclinedly installed on the secondary worktable. The electric cylinder three is installed on the main worktable via a mounting base, and its output end is fixedly connected to the pusher frame that passes through the secondary worktable and can pass through the placement platform. The fixing rod two is fixed to the bottom of the pusher frame and passes through the ear plate on the main worktable. The pressure application assembly includes an electric cylinder, a fixed rod, and a pressure application part. The pressure application part is fixedly installed at the output end of the electric cylinder, and the fixed rod is fixedly installed on the pressure application part and extends upward through the main worktable. The ejection assembly is mounted on the pressure application assembly and includes an electric cylinder two and a push plate. The electric cylinder two is inclined and mounted on the pressure application part through the inclined plate. The push plate is fixedly mounted at the output end of the electric cylinder two. The deburring mechanism includes a motor, a bidirectional lead screw, a guide rail, a movable seat, and tubing. The bidirectional lead screw is fixedly installed at the output end of the motor. The movable seat consists of two opposing sets that slide along the guide rail and are connected to the bidirectional lead screw via a transmission. The grinder is fixedly installed on the movable seat.

[0006] By adopting the above technical solution, the device can automatically push the pipe into the arc groove and then deburr the inner edge of the two ends of the pipe, saving manual operation, time and effort.

[0007] The pusher frame is composed of a base plate and a support frame. The support frame has multiple equally spaced installations on the base plate, and the upper surface of the support frame is inclined.

[0008] The above technical solution is adopted to facilitate the pushing of pipe fittings.

[0009] The auxiliary workbench is provided with through holes for the pusher frame to move up and down, and the size of the holes is adapted to the cross-sectional size of the bottom of the pusher frame. The placement platform has a through-hole for the upper end of the pusher to pass through, and an arc-shaped groove located directly below the pressure part is also provided on the placement platform, with a limiting part protruding on one side of the arc-shaped groove.

[0010] By adopting the above technical solution, the jacking frame can move up and down and extend from the through-hole to push the pipe through its inclined surface, while the limiting part can prevent the subsequent pipe from moving down.

[0011] The electric cylinder is installed in the middle of the main workbench. Two fixing rods are provided and are symmetrically arranged about the vertical central axis of the pressure part. The bottom of the pressure part is provided with arc plates with arc-shaped openings near both ends.

[0012] By adopting the above technical solution, the up-and-down movement of the pressure-applying part is ensured to be stable.

[0013] The ejection assembly is installed on one side of the middle of the pressure section. Its push plate is also inclined.

[0014] By adopting the above technical solution, the pipe fitting is pushed out of the arc-shaped groove.

[0015] The advantages of this utility model's end-treatment device for automotive gas spring tubing are: This device can automatically push the pipe fitting into the arc-shaped groove, and then deburr the inner edge of both ends of the pipe fitting. After processing one pipe fitting, subsequent pipe fittings can be automatically added to the arc-shaped groove for processing. This eliminates the need for manual grinding and deburring, saving manpower, time and effort. Attached Figure Description

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0018] This utility model provides a tube end processing device, such as a tube end processing device for automotive gas springs.

[0019] It includes a main worktable 1 and a secondary worktable 2 that are fixedly connected to each other, a pushing assembly for conveying pipe 16, a pressure application assembly for limiting pipe 16, a deburring mechanism for processing pipe 16, and an ejection assembly 7 for ejecting pipe 16.

[0020] Reference Figure 2-5 The pushing component is described in detail below: The pushing component is supported by the main worktable 1 and the auxiliary worktable 2, and includes a placement platform 3, a pusher 8, an electric cylinder 9, and a fixing rod 10. The placement platform 3 is installed at an angle on the auxiliary worktable 2. The electric cylinder 9 is installed on the main worktable 1 through a mounting base. Its output end is fixedly connected to the pusher 8, which passes through the auxiliary worktable 2 and can pass through the placement platform 3. The fixing rod 10 is fixed to the bottom of the pusher 8 and passes through the ear plate on the main worktable 1. The placement platform 3 is set to an inclined state. When the foremost pipe 16 is pushed, the subsequent pipes 16 can move downwards to supplement it. After the pipe 16 is processed, it is pushed out from the arc groove 303 and can continue to slide down along the inclined surface of the placement platform 3 for collection. Of course, the design of the pusher 8 reduces the use of materials while ensuring that the pusher 8 can push the pipe fitting 16 normally; the pusher 8 is composed of a base plate and a support frame, and the support frame has multiple equally spaced installations on the base plate, and the upper surface of the support frame is inclined. In addition, in order to allow the pusher frame 8 to move up and down smoothly, a through hole 201 is provided on the auxiliary worktable 2 for the pusher frame 8 to move up and down. Its size is adapted to the cross-sectional size of the bottom of the pusher frame 8, so that the electric cylinder 3 9 can push and pull the pusher frame 8 to move up and down smoothly. The fixing rod 2 10 provided at the bottom of the pusher frame 8 passes through the ear plate on the main worktable 1, which allows it to move up and down in a stable longitudinal direction. To allow the pipe fitting 16 to slide smoothly on the inclined surface of the placement platform 3, a through-hole 301 is provided on the placement platform 3 for the upper end of the pusher 8 to pass through. The through-holes 301 are evenly spaced so that the pusher 8 will not stop sliding due to the through-holes 301. An arc-shaped groove 303 is also provided on the placement platform 3, located directly below the pressure application part 6. A limiting part 302 protrudes from one side of the arc-shaped groove 303. The arc-shaped groove 303 can work with the guard plate at the bottom of the pressure application part 6 to limit the pipe fitting 16. The limiting part 302 can prevent the pipe fitting 16 on the placement platform 3 from sliding downward.

[0021] Reference Figure 1-3 The pressure application component is described in detail as follows: The pressure application component includes an electric cylinder 4, a fixing rod 5, and a pressure application part 6. The pressure application part 6 is fixedly installed at the output end of the electric cylinder 4, and the fixing rod 5 is fixedly installed on the pressure application part 6 and extends upward through the main worktable 1. Electric cylinder 4 is installed in the middle of the main workbench 1. Two fixing rods 5 are provided and are symmetrically arranged about the vertical central axis of the pressure part 6. The bottom of the pressure part 6 is provided with arc plates with arc-shaped openings near both ends.

[0022] Reference Figure 4 The ejection assembly 7 is installed on the pressure application assembly, including electric cylinder 2 701 and push plate 702. Electric cylinder 2 701 is inclined and installed on the pressure application part 6 through the inclined plate. Push plate 702 is fixedly installed at the output end of electric cylinder 2 701. The ejection assembly 7 is installed on one side of the middle part of the pressure application part 6, and its push plate 702 is also inclined. When electric cylinder 2 701 slowly pushes the push plate 702 downward, the processed pipe fitting 16 can be pushed out from the arc groove 303 through the push plate 702 and slide down along the other end plate of the placement platform 3 for collection.

[0023] Referring to 1-3, the deburring mechanism includes a motor 11, a bidirectional lead screw 12, a guide rail 13, a movable seat 14, and a pipe fitting 16. The bidirectional lead screw 12 is fixedly installed at the output end of the motor 11. The movable seat 14 consists of two opposing sets that slide along the guide rail 13 and are connected to the bidirectional lead screw 12 in a transmission manner. The grinder 15 is fixedly installed on the movable seat 14.

[0024] The implementation principle of the end-processing device for automotive gas spring tubes in this application is as follows: First, place the pipe fittings 16 one by one on the placement platform 3 to await processing. Then, drive the electric cylinder 39 to push the pusher frame 8 upward. The pusher frame 8 pushes the pipe fitting 16 located at the foremost position to flip over the limiting part 302 and into the arc-shaped groove 303. (It should be noted that the side of the arc-shaped groove 303 away from the limiting part 302 is raised to prevent the pipe fitting 16 from rolling out of the arc-shaped groove 303 when it flips over the limiting part 302 and enters the arc-shaped groove 303.) At this point, the electric cylinder 4 can be driven to push the fixing rod 5 downward, so that the pressure part 6 can first come into contact with the surface of the pipe fitting 16. No pressure needs to be applied to the pipe fitting 16. The drive motor 11 drives the moving seat 14 to move along the guide rail 13 through the double-acting screw 12, so that the two sets of grinders 15 move in opposite directions until the grinding part at the output end of the grinder 15 contacts the inner ring edge at both ends of the pipe fitting 16. Then, the electric cylinder 4 can be controlled to drive the pressure part 6 to apply pressure to the pipe fitting 16 and then drive the grinder 15 to drive the inner ring edge of the pipe fitting 16 to perform burr treatment. After the pipe fitting 16 is processed, the electric cylinder 39 can be driven to move the pusher 8 downward, so that the top of the pusher 8 moves to a position no higher than the upper surface of the placement platform 3. At this time, the pipe fitting 16 can go down along the slope of the placement platform 3. Under normal circumstances, the pipe fitting 16 at the front of the placement platform 3 will be blocked by the limiting part 302 and will not cross the limiting part 302. However, an inclined plate is set on one side of the pressure part 6 at the position where the push-out component 7 is installed. When the pressure part 6 is not raised, the lowest point of the inclined plate is lower than the highest point of the pipe fitting 16, so it can also prevent the pipe fitting 16 from crossing the limiting part 302. After the first pipe fitting 16 at the front contacts the limiting part 302, the electric cylinder 4 can be driven to move the pressure part 6 upward, and then the electric cylinder 701 can be controlled to push the push plate 702 to push the pipe fitting 16 located in the arc groove 303, pushing the pipe fitting 16 out of the arc groove 303. Then, following the above steps, the subsequent pipe fitting 16 can be moved to the arc groove 303 for processing.

[0025] The device can automatically push the pipe fitting 16 into the arc groove 303, and then deburr the inner edge of the two ends of the pipe fitting 16, saving manual operation, time and effort.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
