Description

Technical Field

[0001] This utility model relates to the field of profile oxidation fixture technology, specifically to a special fixture for profile oxidation on an assembly line. Background Technology

[0002] In the electroplating and electrophoresis processes of aluminum profiles, to facilitate quick fixation of the aluminum profiles before immersion in the electroplating or electrophoresis tank for electroplating, electrophoresis, or oxidation treatments, clamps are generally used to clamp and fix the aluminum profiles onto the electroplating or electrophoresis rack before placing them into the electroplating or electrophoresis tank for processing.

[0003] Existing profile anodizing fixtures typically consist of two clamping parts and a hinged part. The hinged part contains a spring, which drives the clamping parts on both sides to open during use, compressing the spring and causing it to deform. However, since the profiles are usually large, a continuous force needs to be applied from the initial state to open the clamping parts on both sides to a large angle in order to achieve clamping. This is time-consuming and labor-intensive, greatly affecting production efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem this invention aims to solve is that existing clamps require workers to apply force from the initial state to open the clamping parts on both sides at a large angle in order to achieve clamping, which is time-consuming and labor-intensive, and greatly affects production efficiency.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a special clamp for profile oxidation on an assembly line, comprising a first clamping part and a second clamping part. The lower end of the first clamping part is fixedly connected to a first hinge piece arranged on both sides. The lower end of the second clamping part is fixedly connected to a second hinge piece that cooperates with the first hinge pieces on both sides. A rotating shaft is fixedly connected between the first hinge pieces on both sides. The second hinge piece is provided with a rotating hole that cooperates with the rotating shaft. A titanium alloy clamping column is fixedly connected to one end of the second clamping part. An arc-shaped sliding hole coaxial with the rotating shaft is provided on one side of the first hinge piece. An adjusting sliding column that is slidably connected in the arc-shaped sliding hole is fixedly connected to the inner wall of the second hinge piece. A fixed slider and a movable slider are slidably connected in the arc-shaped sliding hole. A fixing mechanism that cooperates with the fixed slider is provided on the first hinge piece. An arc-shaped spring is fixedly connected between the fixed slider and the movable slider.

[0008] As an improvement, the fixing mechanism includes an adjusting sleeve that is rotatably sleeved on the outer wall of the rotating shaft, a connecting rod that is fixedly connected between the adjusting sleeve and the movable slider, and a through-type fixing bolt that is threaded onto one side of the adjusting sleeve.

[0009] As an improvement, the outer wall of the rotating shaft is provided with at least one fixing screw hole that mates with the fixing bolt.

[0010] As an improvement, a limiting slide bar is fixedly connected to one side of the fixed slider, and a limiting slide groove that cooperates with the limiting slide bar is provided in the arc-shaped slide hole.

[0011] As an improvement, both the first clamping part and the second clamping part have grooves on their inner sides.

[0012] As an improvement, a reinforcing rib is fixedly connected to one side of the second clamping part.

[0013] As an improvement, the inner wall of the first clamping part is provided with anti-slip texture.

[0014] The fixed slider is fixedly connected to an arc-shaped slide rod concentric with the arc-shaped slide hole on one side. The movable slider is slidably sleeved on the outer wall of the arc-shaped slide rod. The slide post is provided with a through hole that cooperates with the arc-shaped slide rod.

[0015] (III) Beneficial Effects

[0016] The advantages of this invention compared to the prior art are as follows: when the sliding column does not contact the movable slider, the first clamping part and the second clamping part can swing freely. At this time, the first clamping part and the second clamping part can be opened without applying a large external force. When the first clamping part and the second clamping part are opened to a large angle, the sliding column contacts the movable slider, pushes the movable slider to slide along the arc-shaped sliding hole, and at the same time squeezes the arc-shaped spring to undergo compression deformation. The clamping of the profile can be achieved by the elastic force of the arc-shaped spring. There is no need to apply external force at the beginning, which saves time and effort and greatly improves the clamping speed. Attached Figure Description

[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 of the present utility model. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown, a special clamp for profile oxidation on an assembly line includes a first clamping part 1 and a second clamping part 2. The inner wall of the first clamping part 1 is provided with anti-slip texture 17. The lower end of the first clamping part 1 is fixedly connected to a first hinge piece 3 arranged on both sides. The lower end of the second clamping part 2 is fixedly connected to a second hinge piece 4 that cooperates with the first hinge pieces 3 on both sides. A rotating shaft 5 is fixedly connected between the first hinge pieces 3 on both sides. The second hinge piece 4 is provided with a rotating hole 12 that cooperates with the rotating shaft 5. One end of the second clamping part 2 is fixedly connected to a fixed titanium alloy clamping column 20. The titanium alloy clamping column 20 is wear-resistant, temperature-resistant, acid and alkali-resistant, and has strong impact resistance. The inner sides of both the first clamping part 1 and the second clamping part 2 are provided with grooves 19, which better fit the shape of the profile and make the clamping more secure. A reinforcing rib 21 is fixedly connected to one side of the second clamping part 2, which greatly improves the strength of the clamp.

[0026] The first hinge plate 3 on one side is provided with an arc-shaped sliding hole 6 coaxial with the rotating shaft 5. An adjusting slide post 11 is fixedly connected to the inner wall of the second hinge plate 4 and slidably connected within the arc-shaped sliding hole 6. A fixed slider 7 and a movable slider 8 are slidably connected within the arc-shaped sliding hole 6. A limiting slide bar is fixedly connected to one side of the fixed slider 7. A limiting slide groove that cooperates with the limiting slide bar is provided within the arc-shaped sliding hole 6. The first hinge plate 3 is provided with a fixing mechanism that cooperates with the fixed slider 7. The fixing mechanism includes an adjusting sleeve 14 rotatably sleeved on the outer wall of the rotating shaft 5. A connecting rod 15 is fixedly connected between the sleeve 14 and the movable slider 8. A through-type fixing bolt 13 is threadedly connected to one side of the adjusting sleeve 14. The outer wall of the rotating shaft 5 is provided with at least one fixing screw hole 16 that mates with the fixing bolt 13. An arc-shaped spring 9 is fixedly connected between the fixed slider 7 and the movable slider 8. An arc-shaped sliding rod 10 concentric with the arc-shaped sliding hole 6 is fixedly connected to one side of the fixed slider 7. The movable slider 8 is slidably sleeved on the outer wall of the arc-shaped sliding rod 10. A through hole 18 that mates with the arc-shaped sliding rod 10 is provided on the sliding column 11.

[0027] In practical use, when the first clamping part 1 and the second clamping part 2 are in the closed state, there is a distance between the sliding column 11 and the movable slider 8, so that the first clamping part 1 and the second clamping part 2 can be opened with a small force. When the second clamping part 2 continues to swing along the rotating shaft 5, the second hinge piece 4 on one side drives the sliding column 11 to slide along the arc-shaped sliding hole 6. When the sliding column 11 contacts the movable slider 8, it pushes the movable slider 8 to slide along the arc-shaped sliding hole 6, compressing the arc-shaped spring 9 and causing it to deform. The elastic force of the arc-shaped spring 9 clamps the profile in the first clamping part. When it is necessary to increase the clamping force between the first clamping part 1 and the second clamping part 2, first loosen the fixing bolt 13, push the fixing bolt 13 to drive the adjusting sleeve 14 to swing along the outer wall of the rotating shaft 5, and the adjusting sleeve 14 drives the fixed slider 7 to slide along the arc-shaped sliding hole 6 through the connecting rod 15, so that the fixed slider 7 moves closer to the movable slider 8, further squeezing the arc-shaped spring 9 to cause compression deformation. After the adjustment is completed, tighten the fixing bolt 13 again, so that the fixing bolt 13 is screwed into the fixing screw hole 16, thereby fixing the position of the fixed slider 7.
