Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a rotary cutting device for the end waste material of a dust cover for a rear shock absorber of an automobile. Background Technology

[0002] like Figure 1 As shown, this is a dust cover for a car's rear shock absorber, with a metal frame inside its opening. It effectively prevents road dust, mud, and other foreign objects from entering the shock absorber, avoiding contamination of the lubrication system or covering the shock absorber surface, thus ensuring its normal operation. Through its sealing effect, the dust cover prevents leakage or contamination of the lubricating oil inside the shock absorber, ensuring the lubrication of various components (such as piston rods and oil seals) and reducing the risk of wear. Reducing dust intrusion prevents oil leaks, rust, or mechanical damage to precision components such as oil seals and piston rods caused by friction from impurities, thereby extending the overall service life. The dust cover is injection molded.

[0003] During the injection molding process, the metal frame of the dust cover is pre-set inside the injection mold and then injection molded. After the dust cover is formed, the excess waste material at its opening needs to be removed. Currently, workers manually remove the waste material from the formed dust cover, which is time-consuming, labor-intensive, relatively inefficient, and poses significant safety hazards.

[0004] Therefore, it is desirable to provide a rotary cutting device for the end of a dust cover for a car rear shock absorber, in order to solve the above-mentioned problems. Utility Model Content

[0033] Figure 2 This is a schematic diagram showing the connection between the active roller assembly, the upper limit roller, the moving roller assembly, and the support assembly in this embodiment.

[0034] Figure 3 This is a schematic diagram of the connection between the two limiting members and the support assembly in this embodiment;

[0035] Figure 4 This is a schematic diagram of the structure of a dust cover end waste cutting device for a car rear shock absorber according to this embodiment. Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] This embodiment of a dust cover end waste cutting device for automotive rear shock absorbers includes a support assembly, a drive roller assembly, a moving roller assembly, and a cutting component.

[0038] like Figure 2 As shown, the support assembly includes a base plate 1 and a support frame 2; the support frame 2 is fixed on the base plate 1.

[0039] The active roller assembly includes an active roller 3 and a motor 4; the active roller 3 is horizontally and rotatably disposed in the lower part of the support frame 2; the motor 4 is used to drive the active roller 3 to rotate.

[0040] The moving roller assembly includes a first cylinder 5, a first connecting frame 6, and a moving roller 7; the first cylinder 5 is disposed at the front end of the base plate 1, and the piston rod of the first cylinder 5 is horizontal and points towards the active roller 3; the first connecting frame 6 is connected to the piston rod of the first cylinder 5; the moving roller 7 is rotatably disposed on the first connecting frame 6 and always remains horizontal; the moving roller 7 and the active roller 3 are located at the same height.

[0041] like Figure 4As shown, the cutting component includes a second cylinder 8, a second connecting frame 9, and a cutter 10; the second cylinder 8 is located at the top of the rear end of the support frame 2, and the piston rod of the second cylinder 8 passes obliquely downward through the top of the support frame 2; the second connecting frame 9 is fixed to the end of the piston rod of the second cylinder 8; the cutter 10 is located at one end of the second connecting frame 9 and faces the waste material to be cut on the dust cover.

[0042] The first cylinder 5 drives the moving roller 7 to move closer to or away from the drive roller 3. When a dust cover for the waste material to be cut needs to be placed, the first cylinder 5 drives the moving roller 7 away from the drive roller 3, and then places the dust cover for the waste material to be cut between the drive roller 3 and the moving roller 7. The first cylinder 5 is driven again, causing the moving roller 7 to move closer to and adhere to the dust cover. The motor 4 is started, and the drive roller 3 rotates. Under the limiting action of the moving roller 7, the dust cover rotates accordingly. The second cylinder 8 is started, and the second connecting frame 9 moves diagonally downward, causing the cutter 10 to move downward. In this way, the dust cover rotates, and the cutter 10 cuts off the waste material at the end of the dust cover.

[0043] In this embodiment, as Figure 3 As shown, limiting components are provided on both sides of the lower front end of the support frame 2. The limiting components include bolts 11 and limiting plates 12. The end of the bolt 11 is horizontal and passes through the inner wall of the support frame 2. The limiting plate 12 is fixed to the end of the bolt 11. With this setting, the distance between the limiting plates 12 on the two limiting components can be adjusted to limit the dust cover of the waste material to be cut in the left and right directions, so that the cutting part is more stable and effective.

[0044] In this embodiment, as Figure 3 As shown, the upper part of the support frame 2 is horizontally and rotatably equipped with an upper limit roller 13, which is located directly above the limiting member; this arrangement limits the dust cover in the vertical direction, further ensuring that the dust cover rotates smoothly when cutting waste materials.

[0045] In this embodiment, the surfaces of the active roller 3, the moving roller 7, and the upper limit roller 13 are all covered with a rubber layer (not shown in the drawing), which can increase the friction with the outer wall of the dust cover and better drive the dust cover to rotate.

[0046] In this embodiment, guide rails 14 are provided on both sides of the front end of the base plate 1, and the guide rails 14 are arranged along the moving direction of the piston rod of the first cylinder 5; the lower parts of both ends of the first connecting frame 6 are slidably arranged on the two guide rails 14 respectively; this arrangement effectively ensures the accuracy of the moving direction of the first connecting frame 6.

[0047] Similarly, in this embodiment, as Figure 4As shown, guide rods 15 are fixed at both ends of the second connecting frame 9, and the guide rods 15 slide through the top of the support frame 2; with this configuration, when the piston rod of the second cylinder 8 moves, the accuracy of the moving direction of the second connecting frame 9 is effectively ensured, and the cutter 10 is ensured to reach the designated cutting position.

[0048] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
