Description

Technical Field

[0001] The utility model relates to the technical field of electrophoretic coating equipment, in particular to a clamp for electrophoretic coating. Background Art

[0002] Aluminum alloy profiles are the most widely used type of non-ferrous metal structural materials in industry. They have been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction, decoration, and chemical industries. During the processing of existing aluminum alloy profiles, they need to be fixed by electrophoretic coating fixtures for electrophoretic coating. However, the existing electrophoretic coating fixtures for aluminum alloy profiles cannot clamp the aluminum alloy profiles well during use, resulting in instability during coating, reducing the coating effect and being unfavorable for long-term use.

[0003] A Chinese patent with application number 202121498435.5 discloses an electrophoretic coating fixture for aluminum alloy profiles, comprising an outer frame, the inner surface top of which is fixedly connected with two groups of electric telescopic rods, the bottom ends of the two groups of electric telescopic rods are fixedly connected with sliding plates, and the bottom of the sliding plates are connected with two groups of sliders. The electrophoretic coating fixture for aluminum alloy profiles provided by the utility model can achieve a better clamping effect through the provided clamp head, threaded rod and lifting ring, and can be moved more conveniently, wherein the shape of the clamp head is set to a concave-convex shape, which can increase the pressure of the contact surface when clamping the aluminum alloy profile, so as to achieve a better clamping effect, and then the threads on both sides of the threaded rod are relatively reverse threads, so that it can control the two groups of sliders at the same time, which is convenient for use with aluminum profiles of different thicknesses, and finally, through the provided lifting ring, the clamp can be lifted by a crane, making it more convenient when working.

[0004] However, when the above patented technology is used in practice, it can only be applied to the fixing of plate-shaped aluminum alloy profiles. When users use aluminum alloy profiles, they usually also use cylindrical aluminum alloy profiles. It can be seen from the specification and drawings disclosed in the above patented technology that the aluminum alloy profile clamp provided by the above patented technology is obviously not capable of clamping and fixing cylindrical aluminum alloy profiles, so that workers have to prepare a new set of electrophoretic coating clamps when electrophoretically coating such aluminum alloy profiles, thereby increasing the cost of factory production.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0023] like Figures 1 to 4 As shown, the utility model is a clamp for electrophoretic coating, comprising: a U-shaped plate 1, a clamping mechanism for clamping and fixing the aluminum alloy profile;

[0024] The clamping mechanism includes: a connecting plate 14 arranged at the bottom of the U-shaped plate 1, a clamping block 17 fixedly installed on one side of the connecting plate 14, an anti-slip block 18 fixedly installed on one side of the clamping block 17, a V-shaped clamping plate 15 fixedly installed on the other side of the connecting plate 14, an anti-slip pad 16 fixedly installed on one side of the V-shaped clamping plate 15, and a moving component for driving the connecting plate 14 to move; the moving component includes: a movable plate 4 arranged in the inner cavity of the U-shaped plate 1, a mounting frame 6 fixedly installed at the bottom of the movable plate 4, a threaded rod 11 rotatably installed on the inner wall of the mounting frame 6, the threads of the outer edge of the threaded rod 11 near the two ends are in opposite directions, a threaded seat 12 is threadedly installed on the outer edge of the threaded rod 11, and the bottom of the threaded seat 12 is connected to the connecting plate 14 The top is fixedly connected, and a guide rod 13 is penetrated and installed on the side wall of the threaded seat 12. Both ends of the guide rod 13 are fixedly connected to the inner wall of the installation frame 6. Through the setting of the guide rod 13, the threaded seat 12 can be limited and guided, and a rotating unit that drives the threaded rod 11 to rotate can be provided. The rotating unit includes: a motor 7 fixedly installed on the top of the movable plate 4, a rotating shaft fixedly installed on the power output shaft of the motor 7, a driving pulley 8 fixedly installed at one end of the rotating shaft, a driven pulley 10 fixedly sleeved on the outer edge of the threaded rod 11, and a linkage belt 9 installed between the driving pulley 8 and the driven pulley 10. A rectangular opening is opened on the movable plate 4, and the outer edge of the linkage belt 9 passes through the inner cavity of the rectangular opening;

[0025] When the plate-shaped aluminum alloy profile is subjected to electrophoresis, the plate-shaped aluminum alloy profile is placed between two V-shaped clamping plates 15. At this time, the driving pulley 8 is started, and the power output shaft of the driving pulley 8 drives the rotating shaft to rotate, and the driving pulley 8 drives the interlocking belt 9 to rotate through the rotating shaft, and the interlocking belt 9 drives the driven pulley 10 to rotate through the driven pulley 10. The threaded rod 11 is driven to rotate through the driven pulley 10. Since the threads of the outer edges of the threaded rod 11 near the two ends are in opposite directions, the rotation of the threaded rod 11 can simultaneously drive the two threaded seats 12 to approach or move away from each other, and the two threaded seats 12 can be driven to move inward by moving the adjacent connecting plates 14 closer to each other, and the adjacent V-shaped clamping plates 15 can be driven inward by the two connecting plates 14, so that the plate-shaped aluminum alloy profile can be clamped and fixed;

[0026] When electrophoresis is performed on the inner side of the cylindrical aluminum alloy profile, the cylindrical aluminum alloy profile is placed between the two V-shaped clamping plates 15. At this time, the active pulley 8 is started to drive the two threaded seats 12 to approach or move away from each other. The two threaded seats 12 approach each other and the adjacent connecting plates 14 can be driven to move inward. The two connecting plates 14 drive the adjacent V-shaped clamping plates 15 to move inward, so that the cylindrical aluminum alloy profile is located in the V-shaped groove cavity of the two V-shaped clamping plates 15. The V-shaped design of the V-shaped clamping plates 15 facilitates the clamping and fixing of cylindrical aluminum alloy profiles of different diameters. The anti-skid pad 16 can increase the friction between the V-shaped clamping plate 15 and the outer side of the cylindrical aluminum alloy profile, thereby improving the firmness of the V-shaped clamping plate 15 to the cylindrical aluminum alloy profile.

[0027] When electrophoresis is performed on the outer side of the cylindrical aluminum alloy profile, the cylindrical aluminum alloy profile is sleeved on the outer edges of the two clamping blocks 17. At this time, the active pulley 8 is started to drive the two threaded seats 12 to approach or move away from each other. The two threaded seats 12 move away from each other and the adjacent connecting plates 14 can be driven to move outward, and the adjacent clamping blocks 17 are driven to move inward through the two connecting plates 14, so as to clamp and fix the inner wall of the cylindrical aluminum alloy profile. Since the clamping block 17 has a certain moving range, it is convenient to clamp and fix cylindrical aluminum alloy profiles of different diameters. The anti-sliding block 18 is set to increase the friction between the clamping block 17 and the inner wall of the cylindrical aluminum alloy profile, thereby improving the firmness of the clamping block 17 to the cylindrical aluminum alloy profile. The shape of the clamping end of the anti-sliding block 18 is set to be concave and convex, which can increase the pressure of the contact surface when clamping the inner wall of the cylindrical aluminum alloy profile, so as to achieve a better clamping effect.

[0028] From the above, it can be seen that the utility model can fix aluminum alloy workpieces of different shapes through the cooperation of the V-shaped clamping plate 15 and the clamping block 17, so that the factory only needs to use the corresponding V-shaped clamping plate and clamping block when processing different aluminum alloy workpieces, thereby reducing the factory's production costs.

[0029] An electric telescopic rod 3 is fixedly installed on the top of the inner cavity of the U-shaped plate 1, and the bottom end of the electric telescopic rod 3 is fixedly connected to the top of the movable plate 4. By starting the electric telescopic rod 3, the telescopic end of the electric telescopic rod 3 is extended, so that the aluminum alloy profile is placed inside the electrophoretic coating pool for electrophoretic coating.

[0030] A lifting lug 2 is fixedly installed on the top of the U-shaped plate 1. Through the arrangement of the lifting lug 2, a cable can be used to pass through two groups of lifting lugs 2 to lift the U-shaped plate 1 and then move it to the electrophoretic coating pool.

[0031] A slide bar 5 is fixedly installed on the side wall of the movable plate 4, a slide groove is opened on the inner wall of the U-shaped plate 1, and the slide bar 5 is located in the inner cavity of the slide groove. By sliding the slide bar 5 in the inner cavity of the slide groove, the movable plate 4 can be limited to avoid displacement when the movable plate 4 moves.

[0032] Working principle: When in use, the aluminum alloy profile is clamped and fixed by the clamping mechanism, and then the U-shaped plate 1 is lifted by a cable passing through two sets of lifting ears 2, and then moved to the electrophoretic coating pool, and then the electric telescopic rod 3 is started to extend the telescopic end of the electric telescopic rod 3, so that the aluminum alloy profile is placed inside the electrophoretic coating pool for electrophoretic coating.

[0033] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
