Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a welding clamping device for irregularly shaped workpieces. Background Technology

[0002] When a welding machine performs welding processing, it first uses a fixture to clamp and fix the workpiece to be welded, so as to facilitate the smooth progress of subsequent processing and thus ensure the stability and reliability of welding quality.

[0003] The workpiece welding clamping device and its pressing mechanism mentioned in the existing Chinese patent (authorization announcement number: CN217913710U) can fix the left clamp and the right top plate to the outer surface of the fixed sleeve rod and the second fixed sleeve rod respectively through the sleeve ring. Through the cooperation of the clamping ring, the screw and the rotating rod, when needed, the operator can remove the screw by rotating the rotating rod to disassemble the sleeve ring, the left clamp and the right top plate, which facilitates the replacement of the clamp.

[0004] Currently, most methods for clamping and fixing workpieces use fixtures. While this can improve the stability of the workpiece during processing, welding slag is easily generated at high temperatures during the welding process. This slag can fall onto the welding table, making the work area messy and requiring workers to use brushes to clean the welding table, thus increasing their workload. Utility Model Content

[0005] The purpose of this invention is to solve the problem that workers need to use brushes to clean the welding table, which increases their workload. This invention provides a welding clamping device for irregularly shaped workpieces.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A welding clamping device for irregularly shaped workpieces includes a base, a hydraulic telescopic rod fixedly connected to the top of the base, a connecting seat fixedly connected to the output end of the hydraulic telescopic rod, a rotating seat rotatably connected to the end of the connecting seat away from the hydraulic telescopic rod, the rotating seat being concave in shape, rollers symmetrically mounted on the side of the rotating seat away from the connecting seat, vertical plates fixedly connected to the ends of the two bases away from each other, a welding table fixedly connected to the bottom of the vertical plates, a collecting mechanism provided on the top of the welding table, and a reinforcing mechanism provided on the top of the rotating seat.

[0008] By adopting the above technical solution, the workpiece is placed on the welding table, and then the hydraulic telescopic connecting seat is activated to move. The movement of the connecting seat drives the rotating seat to move. When the rotating seat moves, it will come into contact with the workpiece. When it encounters an irregularly shaped workpiece with an inclined surface, the roller moves on the outside of the workpiece, causing the rotating seat to rotate, so that the roller is in close contact with the workpiece, thereby completing the clamping of the irregularly shaped workpiece. The collection mechanism reduces the inconvenience of manual cleaning, and the reinforcement mechanism can improve the stability of the workpiece during processing.

[0009] Furthermore, the collection mechanism includes a collection seat fixedly connected to the top of the welding table. The top of the collection seat has a plurality of collection holes equidistantly provided. A connecting frame is fixedly connected to the inner top wall of the welding table. The top of the connecting frame is set to be open. A collection box is slidably arranged inside the connecting frame. The top of the collection box is set to be open. The opening of the collection box is connected to the collection seat.

[0010] By adopting the above technical solution, it is convenient to automatically collect welding slag.

[0011] Furthermore, movable blocks are fixedly connected to both sides of the collection box, and bottom blocks are fixedly connected to both sides of the connecting frame. The movable blocks and bottom blocks overlap, and fixed blocks are fixed to both sides of the connecting frame. A threaded rod is threadedly connected to the top of the fixed block, and a handle is fixedly connected to the top of the threaded rod. The bottom end of the threaded rod passes through the fixed block and is rotatably connected to a clamping block.

[0012] By adopting the above technical solution, the collection box can be fixed in place, thereby improving its stability.

[0013] Furthermore, buffer pads are fixedly connected to the sides of the clamping block and the bottom block that are close to each other.

[0014] By adopting the above technical solution, the impact of the clamping block on the moving block is reduced.

[0015] Furthermore, a guide post is fixedly connected to the top of the clamping block, the top end of the guide post penetrates through the fixed block, and the guide post is slidably connected to the fixed block.

[0016] By adopting the above technical solution, the guide post provides guidance for the clamping block, making the clamping block move more smoothly.

[0017] Furthermore, the reinforcement mechanism includes a reinforcement plate fixedly connected to the top of the rotating seat. A threaded rod is threadedly connected to one side of the reinforcement plate. A handle is fixedly connected to one end of the threaded rod. The end of the threaded rod away from the handle passes through the reinforcement plate and is rotatably connected to an abutment plate. An abutment block is symmetrically fixedly connected to the side of the abutment plate away from the threaded rod. Rotating columns are rotatably connected to both sides of the top of the rotating seat. The rotating columns are rotatably connected to the abutment blocks.

[0018] By adopting the above technical solution, it is convenient to further fix the workpiece, thereby improving the accuracy and quality of workpiece welding.

[0019] In summary, this utility model has at least one of the following beneficial effects;

[0020] 1. In this utility model, when collecting welding slag, the welding slag will enter the collection box through the collection hole and be collected, thereby ensuring the cleanliness of the welding table, reducing the inconvenience of manual cleaning, and allowing workers to devote more time and energy to welding work, thereby improving overall production efficiency.

[0021] 2. In this utility model, when clamping a workpiece, the rotating handle 2 drives the rotating column to abut against the workpiece, thereby further fixing the workpiece and ensuring that the workpiece will not loosen or shift during processing, thus improving the accuracy and quality of workpiece welding.

[0028] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0029] This utility model discloses a welding clamping device for irregularly shaped workpieces.

[0030] Reference Figure 1 and Figure 2A welding clamping device for irregularly shaped workpieces includes a base 1, a hydraulic telescopic rod 2 fixedly connected to the top of the base 1, a connecting seat 3 fixedly connected to the output end of the hydraulic telescopic rod 2, a rotating seat 4 rotatably connected to the end of the connecting seat 3 away from the hydraulic telescopic rod 2, the rotating seat 4 being concave, rollers 5 symmetrically installed on the side of the rotating seat 4 away from the connecting seat 3, a vertical plate 6 fixedly connected to the ends of the two bases 1 away from each other, a welding table 7 fixedly connected to the bottom of the vertical plate 6, a collecting mechanism provided on the top of the welding table 7, and a reinforcing mechanism provided on the top of the rotating seat 4.

[0031] When welding a workpiece, the workpiece is first placed on the welding table 7. Then, the hydraulic telescopic connecting seat 3 is activated to move. The movement of the connecting seat 3 drives the rotating seat 4 to move. When the rotating seat 4 moves, it will come into contact with the workpiece. When it encounters an irregularly shaped workpiece with an inclined surface, the roller 5 moves on the outside of the workpiece, causing the rotating seat 4 to rotate. This makes the roller 5 close to the workpiece, thus completing the clamping of the irregularly shaped workpiece. The collection mechanism facilitates the automatic collection of welding slag, reducing the inconvenience of manual cleaning. The reinforcement mechanism can further reinforce the workpiece, improving the stability of the workpiece during processing.

[0032] Reference Figures 2 to 4 The collection mechanism includes a collection seat 8 fixedly connected to the top of the welding table 7. The top of the collection seat 8 is provided with several collection holes at equal intervals. A connecting frame 9 is fixedly connected to the inner top wall of the welding table 7. The top of the connecting frame 9 is set to be open. A collection box 10 is slidably arranged inside the connecting frame 9. The top of the collection box 10 is set to be open. The opening of the collection box 10 is connected to the collection seat 8.

[0033] The collection box 10 is fixedly connected to two sides by movable blocks 12, the connecting frame 9 is fixedly connected to two sides by bottom blocks 13, the movable blocks 12 and bottom blocks 13 overlap, the connecting frame 9 is fixedly connected to two sides by fixed blocks 14, the top of the fixed blocks 14 is threadedly connected to a threaded rod 15, the top of the threaded rod 15 is fixedly connected to a handle, and the bottom of the threaded rod 15 passes through the fixed blocks 14 and is rotatably connected to a clamping block 16.

[0034] In addition, buffer pads 17 are fixedly connected to the sides of the clamping block 16 and the bottom block 13 that are close to each other.

[0035] When collecting welding slag, the slag will fall onto the collection seat 8. Through the collection hole opened on the collection seat 8, the slag will fall into the collection hole. At this time, under the action of gravity, the slag will fall into the collection box 10 and be collected, thus ensuring the cleanliness of the welding table 7, reducing the inconvenience of manual cleaning, and allowing the staff to devote more time and energy to the welding work, thereby improving the overall production efficiency.

[0036] After a certain amount of welding slag is collected, the staff can pull out the collection box 10 to facilitate the treatment of the welding slag inside. After cleaning, the collection box 10 is placed inside the connecting frame 9. At this time, by rotating the threaded rod 15, the clamping block 16 clamps the moving block 12 downward, thereby fixing the clamping position and fixing the collection box 10 inside the connecting frame 9. This improves the stability of the collection box 10 during operation and reduces the risk of displacement of the collection box 10.

[0037] The buffer pad 17 is a rubber pad, which can absorb and reduce the impact, thereby reducing the impact of the clamping block 16 on the moving block 12.

[0038] When the clamping block 16 moves, the guide post 18 provides guidance for the clamping block 16, making the movement of the clamping block 16 more stable.

[0039] Reference Figure 1 and Figure 2 The reinforcement mechanism includes a reinforcement plate 19 fixedly connected to the top of the rotating seat 4. A threaded rod 20 is threadedly connected to one side of the reinforcement plate 19. A handle 2 is fixedly connected to one end of the threaded rod 20. The end of the threaded rod 20 away from the handle 2 passes through the reinforcement plate 19 and is rotatably connected to an abutment plate 21. An abutment block 22 is symmetrically fixedly connected to the side of the abutment plate 21 away from the threaded rod 20. Rotating columns 23 are rotatably connected to both sides of the top of the rotating seat 4. The rotating columns 23 are rotatably connected to the abutment blocks 22.

[0040] When clamping the workpiece, rotating the second handle drives the second threaded rod 20 to rotate. The rotation of the second threaded rod 20 will drive the abutment plate 21 to move, and the movement of the abutment plate 21 will drive the abutment block 22 to move. After the abutment block 22 moves, the rotating column 23 will rotate, so that the rotating column 23 abuts against the workpiece, thereby completing the further fixation of the workpiece and ensuring that the workpiece will not loosen or shift during the processing, thereby improving the accuracy and quality of the workpiece welding.

[0041] Working principle: The workpiece is placed on the welding table 7, and then the hydraulic telescopic connecting seat 3 is activated to move. The movement of the connecting seat 3 drives the rotating seat 4 to move. When the rotating seat 4 moves, it will come into contact with the workpiece. When it encounters an irregularly shaped workpiece with an inclined surface, the roller 5 moves on the outside of the workpiece, causing the rotating seat 4 to rotate. This makes the roller 5 close to the workpiece, thus completing the clamping of the irregularly shaped workpiece. When collecting welding slag, the welding slag will fall onto the collection seat 8. Through the collection hole opened on the collection seat 8, the welding slag will fall into the collection hole. At this time, under the action of gravity, the welding slag will fall into the collection box 10 and be collected, thus ensuring the cleanliness of the welding table 7 and reducing the inconvenience of manual cleaning.

[0042] The buffer pad 17 is a rubber pad that can absorb and reduce impact, protecting the workpiece from damage. The guide post 18 provides guidance for the clamping block 16, making the movement of the clamping block 16 more stable. By rotating the handle 2, the threaded rod 20 is rotated. The rotation of the threaded rod 20 will drive the abutment plate 21 to move. The movement of the abutment plate 21 will drive the abutment block 22 to move. After the abutment block 22 moves, the rotating post 23 will rotate, so that the rotating post 23 abuts against the workpiece, thereby further fixing the workpiece.
