Description

Technical Field

[0001] This utility model relates to the field of aluminum profile heat treatment technology, specifically to a clamping structure for an aluminum profile heat treatment device. Background Technology

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. The heat treatment technology of aluminum alloys involves selecting a certain heat treatment specification, controlling the heating rate to rise to a certain temperature, holding it at that temperature for a certain time, and then cooling it at a certain rate to change the microstructure of the aluminum alloy. Its main purpose is to improve the mechanical properties of the aluminum alloy, enhance its corrosion resistance, improve its processing performance, and obtain dimensional stability.

[0003] Chinese patent CN216039726U discloses a clamping structure for a heat treatment device for tubular aluminum profiles. This patent discloses a technical solution to protect the outer surface of aluminum profiles and improve the fixing effect. It solves the problem that when existing heat treatment devices for tubular aluminum profiles clamp aluminum profiles, bolts are used for fixing. Springs and arc plates are set in the clamping structure to buffer the fixing of aluminum profiles. However, the curvature of the arc plates does not match the curvature of the tubular aluminum profile. The mismatch in curvature makes it easy for the arc plates to scratch the outer surface of the aluminum profile.

[0004] When in use, the device fixes the aluminum profile by cooperating with the metal fixing spring and the first pressure spring, which improves the fixing effect and does not damage the outer surface of the aluminum profile. However, the L-shaped stretching plate is restricted by the inner stretching limit spring. Repeated stretching over a long period of time can easily lead to a decrease in the elasticity of the inner stretching limit spring, reducing the stability and clamping effect of the L-shaped stretching plate. Therefore, a clamping structure for the aluminum profile heat treatment device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a clamping structure for an aluminum profile heat treatment device, which has the advantage of high stability. It solves the problem that while the device uses a metal fixing spring and a first pressure spring to fix the aluminum profile and improve the fixing effect without damaging the outer surface of the aluminum profile, the L-shaped stretching plate is restricted by an inner stretching limit spring. However, repeated stretching over a long period of time can easily lead to a decrease in the elasticity of the inner stretching limit spring, reducing the stability of the L-shaped stretching plate and the fixing effect of the aluminum profile.

[0025] 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 some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1 to 4 The aluminum profile heat treatment device clamping structure in this embodiment includes an aluminum profile heat treatment device clamping structure body 1, a support base plate 2 disposed on the aluminum profile heat treatment device clamping structure body 1, and two L-shaped stretching plates 3 slidably connected to the support base plate 2. The bottom surfaces of the two L-shaped stretching plates 3 are fixedly connected to a drive plate 4.

[0027] A mounting bracket 10 is fixedly connected to the bottom surface of the support base plate 2. Two mounting plates 7 are fixedly connected to the bottom surface of the support base plate 2. A drive rod 6 with one end passing through the mounting bracket 10 and the mounting plate 7 is movably connected to the left inner wall and the right inner wall of the mounting bracket 10 through the bearing. A screw 6 with one end extending into the drive rod 6 is fixedly connected to the opposite side of the two drive plates 4.

[0028] The fixed frame 10 is a U-shaped frame. The two drive rods 6 are rotatably connected to the two mounting plates 7 through bearings. The two drive rods 6 have threaded holes on the side near the drive plate 4. The two screws 5 extend into the two threaded holes and are threadedly connected to them. The threads on the two screws 5 are opposite.

[0029] Specifically, the tubular aluminum profile is placed on the clamping structure body 1 of the aluminum profile heat treatment device. The drive rod 6 rotates, and through the threaded connection between the drive rod 6 and the screw 5 and the sliding connection between the L-shaped stretching plate 3 and the support base plate 2, the screw 5 drives the drive plate 4 to move, and the L-shaped stretching plate 3 moves to fix the aluminum profile.

[0030] Example 2: Please refer to Figures 1 to 4 In this embodiment, based on the first embodiment, a drive assembly is provided on the fixed frame 10. The drive assembly includes a rotating rod 11. One end of the rotating rod 11 is rotatably connected to the bottom surface of the fixed frame 10 through a bearing, and the other end passes through the fixed frame 10 and extends to the bottom surface of the support base plate 2. An active bevel gear 12 is fixedly installed on the outer peripheral wall of the rotating rod 11. A driven bevel gear 8 that meshes with the active bevel gear 12 is fitted on the outer peripheral wall of both drive rods 6. A rotating plate 9 is fixedly connected to the bottom surface of the rotating rod 11.

[0031] The rotating rod 11 is rotatably connected to the support base plate 2 via a bearing, and the driving bevel gear 12 and the two driven bevel gears 8 are all located inside the fixed frame 10.

[0032] Specifically, rotating the rotating plate 9 causes the rotating rod 11 to rotate, which in turn causes the driving bevel gear 12 to rotate. Through the meshing between the driving bevel gear 12 and the driven bevel gear 8, the driving rod 6 is driven to rotate.

[0033] Example 3: Please refer to Figures 1 to 4 In this embodiment, based on Embodiment 1 and Embodiment 2, a fixing component is provided on the fixing frame 10. The fixing component includes two fixing plates 15, both of which are fixedly connected to the bottom surface of the fixing frame 10. Telescopic rods 16 are fixedly connected to the opposite sides of the two fixing plates 15, and baffles 18 are fixedly connected to the opposite sides of the two telescopic rods 16. A positioning groove 20 is provided on the outer peripheral wall of the rotating plate 9. A positioning rod 19 with one end extending into the positioning groove 20 is fixedly connected to the opposite sides of the two baffles 18. Springs 17, which are fixedly connected to the fixing plates 15 and the baffles 18 respectively, are fitted on the outer peripheral walls of the two telescopic rods 16. Two sliding grooves 14 are provided on the bottom surface of the fixing frame 10, and a sliding plate 13 with one end extending into the sliding groove 14 is fixedly connected to the top surface of the two baffles 18.

[0034] The positioning rod 19 and the positioning groove 20 are fitted together. The positioning groove 20 is an annular groove. The sliding plate 13 and the sliding groove 14 are slidably connected. The baffle 18 and the fixing plate 15 are fitted together. The fixing plate 15 is an L-shaped plate. The telescopic rod 16 consists of a sleeve and a moving rod. One end of the moving rod passes through and extends into the interior of the sleeve. A limiting block located inside the sleeve is fixedly connected to the outside of the moving rod. A through hole adapted to the moving rod is opened on one side of the sleeve.

[0035] It should be noted that in the initial state, the baffle 18 itself exerts a pulling force on the telescopic rod 16 and the spring 17, causing the telescopic rod 16 and the spring 17 to be in a compressed state. Through the elastic force of the spring 17, the positioning rod 19 and the positioning groove 20 are made to fit together, thus fixing the rotating plate 9.

[0036] Specifically, pulling the slide plate 13 causes the baffle 18 to move, which in turn moves the positioning rod 19. The movement of the baffle 18 compresses the telescopic rod 16 and the spring 17, causing them to retract. Through the sliding connection between the slide plate 13 and the slide groove 14, the baffle 18 is supported, improving its stability. After fixing, the slide plate 13 is released, and the positioning rod 19 is pushed back to its original position by the action of the spring 17. The positioning rod 19 is then inserted into the positioning groove 20 to fix the rotating plate 9.

[0037] The working principle of the above embodiments is as follows:

[0038] The tubular aluminum profile is placed on the clamping structure body 1 of the aluminum profile heat treatment device. Pulling the slide plate 13 causes the slide plate 13 to move the baffle 18, which in turn moves the positioning rod 19. The movement of the baffle 18 compresses the telescopic rod 16 and the spring 17, causing them to retract. The sliding connection between the slide plate 13 and the slide groove 14 supports the baffle 18, improving its stability. Rotating the rotating plate 9 causes the rotating rod 11 to rotate, which in turn causes the drive bevel gear 12 to engage. The rotating plate 9 rotates through the meshing of the driving bevel gear 12 and the driven bevel gear 8, which drives the drive rod 6 to rotate. Through the threaded connection between the drive rod 6 and the screw 5 and the sliding connection between the L-shaped stretching plate 3 and the support base plate 2, the screw 5 drives the drive plate 4 to move, which in turn moves the L-shaped stretching plate 3 to fix the aluminum profile. After fixing, the slide plate 13 is released, and the positioning rod 19 is pushed to reset by the action of the spring 17. The positioning rod 19 is inserted into the positioning groove 20 to fix the rotating plate 9.
