Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, specifically a clamping fixture for processing cylindrical aluminum profiles. Background Technology

[0002] Cylindrical aluminum profiles, as the name suggests, refer to aluminum materials with a circular cross-section. These profiles are obtained by heating aluminum to a certain temperature and then extruding it through a mold. Cylindrical aluminum profiles are lightweight, high-strength, and corrosion-resistant, and therefore have wide applications in many fields.

[0003] However, in existing technologies, the traditional processing of cylindrical aluminum profiles typically requires placing the aluminum material on a worktable or in a fixture. Some existing fixtures, however, may cause unnecessary damage to the aluminum material due to excessive clamping force, resulting in poor clamping performance. Furthermore, due to the weight of the aluminum material itself, friction may occur between the aluminum surface and the inside of the fixture during handling, causing surface damage. Therefore, we provide a clamping fixture for processing cylindrical aluminum profiles. Utility Model Content

[0004] The purpose of this invention is to provide a clamping fixture for processing cylindrical aluminum profiles, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for processing cylindrical aluminum profiles, comprising: a clamping mechanism, the clamping mechanism including a base, fixed seats provided on both sides of the top of the base, a placement clamping seat provided on the top of each of the two fixed seats, a mounting shell provided in the cavity opened on both sides of each of the two placement clamping seats, a spring piece provided inside each of the four mounting shells, a pulley bracket provided at the end of each of the four mounting shells away from the fixed seats, a self-locking pulley movably mounted on each of the four pulley brackets, an arc-shaped clamping plate provided on the top of each of the two placement clamping seats, a piston rod provided on the top of each of the two arc-shaped clamping plates, a hydraulic cylinder provided at the top of each of the two piston rods, telescopic guide rods provided on both sides of the top of the two arc-shaped clamping plates, and a support mechanism provided on the top of the base.

[0006] As a further preferred embodiment of this technical solution, the support mechanism includes a support frame, the bottom of which is fixedly connected to the top of the base, and the bottoms of the two hydraulic cylinders are both fixedly installed on the top of the support frame.

[0007] As a further preferred embodiment of this technical solution, the top ends of the four telescopic guide rods are all fixedly connected to the top side of the inner wall of the support frame, and the bottom of the base is fixedly connected to four anti-slip feet.

[0008] As a further preferred embodiment of this technical solution, the bottom of the fixing seat is fixedly connected to the top of the base, the top of the fixing seat is fixedly connected to the bottom of the placement clamp, and mounting shells are fixedly connected to the cavities opened on both sides of the placement clamp.

[0009] As a further preferred embodiment of this technical solution, one end of the spring piece is fixedly connected to the inner wall of the mounting housing away from the pulley bracket, and the other end of the spring piece is fixedly connected to the end of the pulley bracket away from the self-locking pulley.

[0010] As a further preferred embodiment of this technical solution, the pulley bracket is slidably connected to the inner wall of the mounting housing at the outer end near the spring piece, and the top end of the piston rod is movably installed through the top of the support frame and at the output end of the bottom of the hydraulic cylinder.

[0011] As a further preferred embodiment of this technical solution, the bottom end of the piston rod is fixedly connected to the top of the arc-shaped clamping plate, and the bottom end of the telescopic guide rod is fixedly connected to the top of the arc-shaped clamping plate.

[0012] This utility model provides a clamping fixture for processing cylindrical aluminum profiles, which has the following advantages:

[0013] (1) The present invention makes it easier to place aluminum material on two placement clamps by means of a self-locking pulley. The self-locking effect of the pulley locks the pulley part to prevent slippage between the pulley and the aluminum material, making it easier to pick up and put down the aluminum material. The hydraulic cylinder is activated to drive the arc-shaped clamping plate to move up and down, pressing down to clamp the aluminum material on the placement clamp. When subjected to continuous downward clamping, the pressure generated will be transmitted to the pulley bracket. As a result, the pulley bracket will be indented into the mounting shell under the downward pressure, and the spring sheet will be squeezed. When the pulley bracket is found to be indented, the hydraulic cylinder is stopped immediately to avoid unnecessary damage to the aluminum material due to excessive clamping force.

[0014] (2) The present invention can provide effective support for the hydraulic cylinder through the support frame, ensuring the stability of the hydraulic cylinder during operation. The anti-slip feet can increase the friction between the equipment and the ground, preventing the equipment from sliding or moving during use. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a clamping fixture for processing cylindrical aluminum profiles includes: a clamping mechanism 1, which includes a base 11. Fixed seats 12 are provided on both sides of the top of the base 11. Placement clamps 13 are provided on the top of each of the two fixed seats 12. Mounting shells 14 are provided in the cavities on both sides of each of the two placement clamps 13. The bottom of the fixed seats 12 is fixedly connected to the top of the base 11, and the top of the fixed seats 12 is fixedly connected to the bottom of the placement clamps 13. Mounting shells 14 are fixedly connected in the cavities on both sides of the placement clamps 13. Spring pieces 15 are provided inside each of the four mounting shells 14. A pulley bracket 16 is provided at the end of each of the four mounting shells 14 away from the fixed seats 12. Self-locking pulleys 17 are movably mounted on each of the four pulley brackets 16. One end of the spring piece 15 is far from the inner wall of the mounting shell 14. One end of the spring plate 15 is fixedly connected to the side of the pulley bracket 16 away from the self-locking pulley 17. The top of each of the two placement clamps 13 is provided with an arc-shaped clamping plate 111. The top of each of the two arc-shaped clamping plates 111 is provided with a piston rod 19. The top of each of the two piston rods 19 is provided with a hydraulic cylinder 18. The outer side of the pulley bracket 16 near the spring plate 15 is slidably connected to the inner wall of the mounting shell 14. The top of the piston rod 19 passes through the top of the support frame 21 and is movably installed at the bottom output end of the hydraulic cylinder 18. The top sides of the two arc-shaped clamping plates 111 are provided with telescopic guide rods 110. The bottom end of the piston rod 19 is fixedly connected to the top of the arc-shaped clamping plate 111. The bottom end of the telescopic guide rod 110 is fixedly connected to the top of the arc-shaped clamping plate 111. The top of the base 11 is provided with a support mechanism 2.

[0023] In this embodiment, when the clamping fixture is needed to clamp a cylindrical aluminum material, the aluminum material can be placed on the placement clamp 13. The surface of the aluminum material will contact the self-locking pulley 17, and the aluminum material will slide on the pulley, making it easy to place the aluminum material on the two placement clamps 13. The two placement clamps 13 will provide support for the aluminum material. The self-locking effect of the self-locking pulley 17 will lock the pulley to prevent slippage between the pulley and the aluminum material. After the hydraulic cylinder 18 is activated, the piston rod 19 will move up and down, and the arc-shaped clamping plate 111 will move up and down synchronously. The telescopic guide rod 110 can improve the stability of the arc-shaped clamping plate 111 when it is raised and lowered, so that the aluminum material placed on the clamping seat 13 can be pressed down and clamped. In order to avoid unnecessary damage to the aluminum material due to excessive clamping force, the pressure generated when the aluminum material is subjected to continuous downward clamping will be transmitted to the pulley bracket 16. As a result, the pulley bracket 16 will be dented into the mounting shell 14 under the downward pressure, and will squeeze the spring piece 15. Therefore, when the operator finds that the pulley bracket 16 is dented, the hydraulic cylinder 18 will be stopped immediately, so that the aluminum material will be fixedly clamped.

[0024] like Figures 1-4 As shown, the support mechanism 2 includes a support frame 21, the bottom of the support frame 21 is fixedly connected to the top of the base 11, the bottoms of the two hydraulic cylinders 18 are fixedly installed on the top of the support frame 21, the tops of the four telescopic guide rods 110 are fixedly connected to the top side of the inner wall of the support frame 21, and the bottom of the base 11 is fixedly connected to four anti-slip feet 22.

[0025] In this embodiment, the support frame 21 provides effective support for the hydraulic cylinder 18, ensuring the stability of the hydraulic cylinder 18 during operation. The anti-slip feet 22 increase the friction between the equipment and the ground, preventing the equipment from sliding or moving during use.

[0026] This utility model provides a clamping fixture for processing cylindrical aluminum profiles, and its working principle is as follows:

[0027] When a cylindrical aluminum material needs to be securely clamped, it is first placed on the placement clamp 13. As the aluminum material is placed, its surface comes into contact with the self-locking pulley 17, allowing it to slide easily along the pulley. This facilitates accurate positioning between the two placement clamps 13. Once the aluminum material is in the correct position, the self-locking function of the pulley 17 effectively prevents any accidental slippage between the pulley and the aluminum material, ensuring safety and stability during processing. After the hydraulic cylinder 18 moves, it drives the piston rod 19 to move up and down, and the arc-shaped clamping plate 111 will move up and down synchronously. Therefore, it can press down and clamp the aluminum material placed on the clamping seat 13. When the aluminum material is subjected to continuous downward clamping, the pressure generated will be transmitted to the pulley bracket 16. As a result, the pulley bracket 16 will be indented into the mounting shell 14 under the downward pressure, and will squeeze the spring piece 15. Therefore, when the operator finds that the pulley bracket 16 is indented, the hydraulic cylinder 18 will be stopped immediately, so that the aluminum material will be fixedly clamped.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
