Description

Technical Field

[0001] This utility model relates to the field of shock absorber cylinder processing technology, and in particular to a clamping fixture. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In the processing of aluminum cylinders for motorcycle shock absorbers, clamping fixtures are one of the key auxiliary tools. Currently, most commonly used clamping fixtures employ a fixed clamping structure. Their basic principle is that the clamping ends of the fixture are brought close together to fix the aluminum cylinder, facilitating subsequent cutting, deburring, and other processing operations. However, once the aluminum cylinder is clamped, the clamping position remains fixed and cannot be flexibly adjusted according to different processing requirements. This makes it difficult for the processing device to accurately operate on the corresponding positions of the aluminum cylinder (such as the end or inner wall) during cutting, deburring, and other processing, thus limiting processing flexibility and efficiency, resulting in insufficient processing efficiency. Therefore, a new clamping fixture is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings by providing a clamping fixture that allows for easy adjustment of the cylinder's position after clamping, facilitating subsequent processing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a clamping fixture, comprising:

[0006] The three-jaw chuck mechanism has a transport component at each of its three moving ends. The three-jaw chuck mechanism can drive each moving end to move the corresponding transport component to a side closer to or farther from the axis of the three-jaw chuck mechanism.

[0007] The transport assembly includes a frame disposed at the corresponding moving end of the three-jaw chuck mechanism. A conveying component is disposed on the frame. The cylinder is conveyed from one side of the three-jaw chuck mechanism to its axis. When the conveying component contacts and moves with the cylinder located at the axis of the three-jaw chuck mechanism, it can convey the cylinder to the other side of the three-jaw chuck mechanism.

[0008] A drive unit, which is used to drive the corresponding conveying component to move.

[0009] Furthermore, the conveying component includes multiple rotatable transmission rollers mounted on corresponding frames and transmission belts mounted on each transmission roller. The driving unit includes a motor mounted on the corresponding moving end of the three-jaw chuck mechanism and a transmission component mounted on the moving end of the motor. The transmission component can drive the corresponding transmission roller to rotate and drive the transmission belt to move when the motor is working.

[0010] Furthermore, the conveying component is a guardrail-type conveyor.

[0011] Furthermore, the transport assembly also includes a mounting plate disposed on each frame away from the corresponding moving end of the three-jaw chuck mechanism. The three-jaw chuck mechanism is provided with a plurality of telescopic rods corresponding to each frame. The telescopic rods are provided with springs that contact their telescopic ends, and the moving ends of the telescopic rods contact the mounting plate.

[0012] When the transport component moves with the moving end of the three-jaw chuck mechanism, the telescopic rod can extend and retract accordingly, and the spring can cooperate with the telescopic rod to support the frame.

[0013] Furthermore, it also includes an isolation component for isolating impurities generated during the processing of the cylinder when the cylinder is held by each transport component and is in a processing state.

[0014] Furthermore, the isolation component includes a transmission pipe disposed at the corresponding moving end of the three-jaw chuck mechanism, one end of the transmission pipe facing each transport component, and a diversion hopper communicating with the end of the transmission pipe facing each transport component, the diversion hopper having multiple air outlets;

[0015] The end of the transmission pipe away from the diversion hopper can be connected to the output end of the fan via a flexible hose. When the fan is working, the isolation component can guide multiple airflows to be discharged from each air outlet and form an air curtain to prevent impurities from flying towards each transport component.

[0016] The beneficial effects of this utility model are reflected in:

[0017] In this invention, at the previous workstation, the shock-absorbing cylinder is conveyed to the center of the disc. At this time, the movement of the three seats can be controlled until each conveying component contacts the cylinder. When the conveying component is not moving, the cylinder is in a stable clamping state. When the drive unit drives the corresponding conveying component to move, the cylinder will move away from the previous workstation. During the movement, part of the cylinder will be exposed. After being exposed to the corresponding position, it will stop, so that the relevant device can perform deburring processing on its end or extend into its interior. It can also perform cutting processing. After processing is completed, the conveying component continues to work, and can continue to convey the processed cylinder to the next workstation. This device can be adapted to various processing devices to clamp the cylinder and cooperate in processing, and also has a conveying function, thus facilitating practical use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-4 This utility model discloses a clamping fixture, including a three-jaw chuck mechanism 1. The three-jaw chuck mechanism 1 includes an annular disc 11, on which three annularly distributed seats 12 are slidably mounted. In use, the three seats 12 can be moved towards or away from the axis of the disc 11 by a power source such as a motor, thereby completing the clamping operation. The three-jaw chuck mechanism 1 mentioned above is common knowledge in the field, so its specific structural composition and working principle will not be described in detail in this article.

[0026] In one embodiment, each of the three discs 11 is provided with a transport assembly 3. The transport assembly 3 includes a frame 31 mounted on each seat 12. The frame 31 is provided with a conveying component 32. The cylinder is conveyed from one side of the three-jaw chuck mechanism 1 to its axis. When the conveying component 32 contacts and moves with the cylinder located at the axis of the three-jaw chuck mechanism 1, it can convey it to the other side of the three-jaw chuck mechanism 1. The corresponding seat 12 is provided with a driving part 4, which is used to drive the corresponding conveying component 32 to move.

[0027] In practice, at the previous workstation, the shock-absorbing cylinder is conveyed to the center of the disc 11. At this time, the three seats 12 can be controlled to move until each conveying component 32 contacts the cylinder. When the conveying component 32 does not move, the cylinder is in a stable clamping state. When the drive unit 4 drives the corresponding conveying component 32 to move, the cylinder will move away from the previous workstation. During the movement, part of the cylinder will be exposed. After being exposed to the corresponding position, it will stop, so that the relevant device can deburr its end or extend into its interior. It can also be used for cutting. After the processing is completed, the conveying component 32 continues to work, and can continue to convey the processed cylinder to the next workstation. This device can be adapted to various processing devices to clamp the cylinder and cooperate in processing. It also has a conveying function, which is convenient for practical use.

[0028] In one embodiment, the conveying component 32 includes a plurality of rotatable transmission rollers mounted on the corresponding frame 31 and a transmission belt disposed on each transmission roller. The driving unit 4 includes a motor 41 mounted on the corresponding base 12 and a transmission component 42 disposed at the moving end of the motor 41. When the motor 41 is working, the transmission component 42 can drive the corresponding transmission roller to rotate and drive the transmission belt to move.

[0029] In a specific implementation, the transmission component 42 may include two transmission wheels and a belt mounted on the two transmission wheels. The two transmission wheels are coaxially mounted on the rotating shaft of the motor 41 and the corresponding transmission roller at one end of the transmission component 42, respectively. At the same time, the outside of the transmission component 42 is covered with a shell. After the motor 41 is started, one of the transmission wheels, together with the belt, drives the other transmission wheel to rotate, and the corresponding transmission roller moves synchronously and drives the transmission belt to move.

[0030] In one embodiment, the conveying component 32 is a guardrail conveyor.

[0031] This design allows the conveying surface of the conveying component 32 to form a U-shaped structure, which can effectively improve the clamping safety when the three conveying components 32 do not contact each other; and the guardrail type conveyor mentioned above is common knowledge in the field, so its specific structure and working principle will not be described in detail in this article.

[0032] In one embodiment, the transport assembly 3 further includes a mounting plate 33 installed on the side of each frame 31 away from the corresponding seat 12. A plurality of telescopic rods 5 corresponding to each frame 31 are installed on the disc 11. A spring is installed inside the telescopic rod 5 and contacts its telescopic end. The moving end of the telescopic rod 5 contacts the mounting plate 33.

[0033] In practice, when the transport component 3 moves with the seat 12, the telescopic rod 5 can extend and retract accordingly, and the spring can cooperate with the telescopic rod 5 to support the frame 31. With this design, the telescopic rod 5 and the seat 12 cooperate to support both sides of the transport component 3, and the telescopic rod 5 can extend and retract synchronously when the transport component 3 moves, thereby ensuring safe adjustment.

[0034] In one embodiment, an isolation component 6 is also included.

[0035] In practice, the isolation component 6 is used to isolate impurities generated during the processing of each transport component 3 when the cylinder is clamped and the cylinder is in a processing state.

[0036] In one embodiment, a connecting plate 2 is installed on the corresponding seat 12, and the isolation component 6 includes a transmission pipe 61 installed on the connecting plate 2. One end of the transmission pipe 61 faces each transport component 3, and a diversion hopper 62 communicating with the end of the transmission pipe 61 facing each transport component 3 is installed therewith. The diversion hopper 62 has multiple air outlets.

[0037] In practice, the end of the transmission pipe 61 away from the diversion hopper 62 can be connected to the output end of the external fan through a hose, while the isolation component 6 can guide multiple airflows to be discharged from each air outlet and form an air curtain when the fan is working. This air curtain acts on the side of the transport component 3 facing the cylinder processing area to prevent impurities from flying towards each transport component 3, so as to ensure the safe operation of the transport component 3.

[0038] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0039] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
