Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum tube processing technology, specifically a clamping device for cutting aluminum tubes. Background Technology
[0002] Aluminum is lightweight and rust-resistant, making it suitable for use as a building decoration material. Currently, in the antique building industry, aluminum is gradually being used to replace wood in the production of decorative components for ancient buildings, which has good environmental and economic benefits. There are many types of decorative components, and their main load-bearing parts or external contours are generally made of aluminum tubes. During production in the factory, long tube blanks are cut into the desired lengths and different angles as needed by a cutting machine. However, aluminum tubes are softer than other metal tubes. When the aluminum tube is thin and long, the two ends are suspended and clamped, which can easily cause the aluminum tube to bend and deform. Therefore, a support mechanism needs to be set up during processing to prevent the aluminum tube from deforming. Summary of the Invention
[0003] The purpose of this invention is to solve the problems existing in the prior art and to provide a clamping device for cutting aluminum tubes.
[0004] The specific solution of this utility model is as follows: a clamping device for cutting aluminum tubes includes a support frame, two linear tracks on the support frame, a slide on the linear tracks, a fixed seat on one end of the support frame, a clamping mechanism on the opposite side of the slide and the fixed seat, a traveling drive mechanism on the slide, the traveling drive mechanism for driving the slide to move along the linear tracks, a through hole in the middle of the support frame, an auxiliary support mechanism below the through hole, the auxiliary support mechanism including a support plate connected to the support frame, a lifting drive mechanism on the support plate, a support block on the top of the lifting drive mechanism, and the support block for auxiliary support of the aluminum tube.
[0005] Furthermore, the clamping mechanism employs a three-jaw chuck.
[0006] Furthermore, the top surface of the support block is provided with an arc-shaped groove.
[0007] Furthermore, the walking drive mechanism includes a servo motor and a rack. The servo motor is fixedly mounted on the slide, and a gear is installed at the output end of the servo motor. The rack is mounted on one side of the support frame and meshes with the gear.
[0008] Furthermore, the auxiliary support mechanism is located in the middle of the support frame.

[0014] See Figure 1-3 This embodiment is a clamping device for cutting aluminum tubes, including a support frame 1. The support frame 1 is provided with two linear rails 2. A slide 9 is mounted on the linear rails 2. A fixed seat is mounted on one end of the support frame 1. A clamping mechanism is mounted on the side of the slide 9 opposite to the fixed seat. A walking drive mechanism is mounted on the slide 9 to drive the slide 9 to move along the linear rails 2. A through hole 3 is provided in the middle of the support frame 1. An auxiliary support mechanism is provided below the through hole 3. The auxiliary support mechanism includes a support plate 5. The support plate 5 is connected to the support frame 1. A lifting drive mechanism 11 is mounted on the support plate 5. A support block 4 is mounted on the top of the lifting drive mechanism 11. The support block 4 is used to assist in supporting the aluminum tube.
[0015] Furthermore, the clamping mechanism employs a three-jaw chuck 10. Furthermore, the top surface of the support block 4 is provided with an arc-shaped groove.
[0016] Furthermore, the walking drive mechanism includes a servo motor 7 and a rack 6. The servo motor 7 is fixedly mounted on the slide 9, and a gear 8 is mounted on the output end of the servo motor 7. The rack 6 is mounted on one side of the support frame 1, and the rack 6 meshes with the gear 8.
[0017] Furthermore, the auxiliary support mechanism is located in the middle of the support frame 1. In this embodiment, the lifting drive mechanism 11 is an electric push rod.
[0018] In operation, this invention moves the sliding bracket to a suitable position according to the length of the aluminum tube. The moving distance is precisely controlled by the servo motor 7, which drives the gear 8 to rotate and roll along the rack 6, thereby moving the entire slide 9 along the linear track 2. When the aluminum tube is long, a support block 4 is needed as an auxiliary support. The support block 4 is lifted by extending the electric push rod to a suitable distance. Both ends of the aluminum tube are clamped by the fixed seat and the three-jaw chuck 10 on the slide 9, respectively. When the aluminum tube is short, no auxiliary support is needed. The electric push rod is fully retracted so that the height of the support block 4 is lower than that of the slide 9, allowing the slide 9 to pass smoothly. The bottom surface of the slide 9 has a partial hollow. This invention is applicable to the processing of aluminum tubes of different diameters and lengths.
