Description

Technical Field

[0001] The invention belongs to the technical field of sled board welding, and in particular relates to a spot welding clamping device of a sled board and a clamping method thereof. Background Art

[0002] The main purpose of a transport sled is to carry goods or passengers, so its carrying capacity is a key feature. In order to achieve this function, its structure is designed to be relatively strong. In polar regions, transport sleds are an important means of transportation. Due to the special geographical environment of the polar regions, road construction is difficult, and sled transportation is particularly important. It can be used to transport scientific research equipment, daily necessities, etc. For example, in the supply of materials to Antarctic scientific research stations, sled transportation can transport a large amount of materials from supply ships on the coast to inland research stations, opening up a transportation route on the snow and ice. The transport sled bears a large weight. In order to prevent the sled from deforming, it is necessary to weld reinforcement ribs on both sides of the sled to make the sled stronger and less prone to deformation.

[0003] During the production process of sled boards, workers are required to hold the reinforcing ribs with one hand and use the other hand to weld and fix them through a welding gun. The reinforcing ribs are usually made of steel plates and are heavy. The workers have to hold them for a long time, which causes high labor intensity and hand muscle fatigue. At the same time, welding sparks can easily injure workers. In addition, manual hand-held fixation is unstable during the welding process, which can easily cause the reinforcing ribs to shift, affecting the welding quality. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a ski plate welding and fixing device for fixing reinforcing ribs.

[0005] The technical solution adopted to solve the above technical problems is: a spot welding clamping device for a sled, comprising a sled, wherein a reinforcing rib clamp is clamped and fixed at a position of the sled for facilitating welding.

[0006] Through the above technical solution, the sled board is used as a product to be welded, and the reinforcing rib clamp can clamp and fix the sled board body to facilitate welding.

[0007] The reinforcing rib clamp comprises a clamping platform arranged on the surface of the sled board, sliding adjustment grooves are provided on both sides of the clamping platform at both ends, a fixed support frame is fixedly connected to the upper surface of the clamping platform at each sliding adjustment groove position, and a swing arm structure is provided at each fixed support frame position.

[0008] Through the above technical solution, the clamping platform can support and install the components of the reinforcement clamp, the sliding adjustment groove facilitates the axial rotation adjustment of the clamping swing arm, so that the adjustment range of the clamping swing arm is wider, and the fixed support frame can fix the positioning adjuster.

[0009] A through slot is formed through the middle of the upper surface of the clamping platform, and a clamping adjustment structure for clamping the ski board is arranged at the through slot of the clamping platform.

[0010] Through the above technical solution, the through groove can realize the limit adjustment of the clamping adjustment structure, and the reinforcing rib clamp can be fixed at the main body of the sled through the clamping adjustment structure.

[0011] Furthermore, the swing arm structure includes a positioning shaft fixed in a fixed support frame position, the outer wall of the positioning shaft is sleeved with a friction outer ring made of rubber material, the surface of the friction outer ring is provided with a number of evenly distributed serrations, and the outer side of the positioning shaft is sleeved with a positioning adjuster, and the positioning adjuster is fixedly connected with a clamping swing arm.

[0012] Through the above technical solution, the positioning shaft supports the positioning adjuster and fixes the clamping swing arm through the positioning adjuster. The friction force of the friction outer ring of the rubber material is large and will not cause the positioning adjuster to be offset or horizontally moved. The clamping swing arm can be installed with a reinforcing rib clamp to clamp and fix the reinforcing rib plate.

[0013] Furthermore, the clamping swing arm is fixedly connected to a damping rotator by clamping a clamping bolt assembly at one end away from the positioning adjuster, and the damping rotator is fixedly connected to a reinforcing rib clamp at one end away from the clamping swing arm, and a clamping plate is slidably connected to the inner wall of the reinforcing rib clamp, and a limiting guide column is fixedly connected to a middle position of one side of the clamping plate, and the limiting guide column and the side wall of the reinforcing rib clamp are slidably connected through, and a return spring is fixedly connected between the middle position of one side of the clamping plate close to the limiting guide column and the reinforcing rib clamp, and the return spring is a compression spring, which can enable the clamping plate to maintain a strong clamping force.

[0014] Through the above technical scheme, the damping rotator makes the damping feeling of the rotation adjustment strong, which is convenient for precise adjustment of the inclination angle of the reinforcing rib clamp and maintaining the required angle, which is convenient for welding. The clamping plate cooperates with the reinforcing rib clamp to clamp and fix the reinforcing rib plate under the action of the reset spring, and the limit guide column can slide and limit the clamping plate in a straight line. The reset spring is a compression spring. When the reinforcing rib plate is inserted between the clamping plate and the reinforcing rib clamp, the reset spring can press the reinforcing rib plate through the clamping plate.

[0015] Furthermore, the clamping adjustment structure includes two symmetrically arranged linkage swing arms that are slidably connected to the inner wall of the through groove, the top positions of the two linkage swing arms are rotatably connected to fixed connecting blocks, the top positions of the fixed connecting blocks are fixedly connected to a movable handle, the lower surface position of the clamping platform is slidably connected to two symmetrically arranged side clamps, and the two linkage swing arms are rotatably connected to the top of the side clamps at one end away from the fixed connecting blocks.

[0016] Through the above technical solution, one end of the linkage swing arm is connected to the side splint and the fixed connecting block, and the side splint can be controlled by a movable handle with a fixed position of the fixed connecting block, so that the side splint can be expanded.

[0017] Furthermore, a support spring is fixedly connected between the side of the two side clamps away from the center of the clamping platform and the side wall of the clamping platform, and a positioning protrusion is fixedly connected near the lower position on the side of the two side clamps close to each other, and a circular arc chamfer is arranged on the side of the positioning protrusion, and an "eight"-shaped chamfer is opened at the bottom position of the two side clamps, and the support spring is a compression spring, which presses the side clamps toward the middle position.

[0018] Through the above technical scheme, when the movable handle is pressed down, the two side clamps expand to both sides, and the support spring is compressed. When the movable handle is released, the two side clamps rebound under the action of the support spring, so that the side clamps are clamped on both sides of the sled board body. When the positioning protrusion is inserted into the fixed installation hole of the sled board body, the fixed installation of the reinforcing rib clamp is more stable, and the positioning protrusion is convenient for inserting into the fixed installation hole. The bottom position of the two side clamps is provided with an "eight"-shaped chamfer, which is convenient for clamping the two side clamps on both sides of the sled board body.

[0019] Furthermore, a control handle is slidably connected through the center of the upper surface of the positioning adjuster, and one end of the control handle located inside the positioning adjuster is fixedly connected to a clamping block, and the clamping block is slidably connected to the inner wall of the positioning adjuster.

[0020] Through the above technical solution, the clamping block tightly presses the friction outer ring under the action of the clamping spring, so that the friction force between the clamping block and the positioning adjuster and the friction outer ring is increased, and the positioning adjuster is fully fixed when the clamping block is not pulled up, so that the reinforcing rib plate is fixed fully and stably.

[0021] Furthermore, the lower surface of the clamping block is arranged in an arc shape and a serrated shape, and a clamping spring is fixedly connected between the upper surface of the clamping block and the inner top wall of the positioning adjuster. The clamping spring is a compression spring, so that the clamping block can fully clamp the friction outer ring.

[0022] Furthermore, the sled board includes a sled board body, and fixed mounting holes are opened through the middle positions of both sides of the sled board body. The two sides of the sled board body are clamped and fixed by two symmetrical side clamps, and the positioning protrusions are slidably connected to the fixed mounting holes at corresponding positions, and reinforcing rib plates are provided at both ends of both sides of the sled board body.

[0023] A clamping method for a spot welding clamping device of a sled board comprises the following specific steps: Step 1. Hold the clamping platform and press the movable handle downward to expand the linkage swing arm to both sides and slide the side clamps to both sides, and place the two side clamps on both sides of the sled body. Release the movable handle so that the two side clamps are close to each other under the action of the support spring, so that the positioning protrusion is inserted into the fixed installation hole, and the reinforcing rib clamp is fixed to the position of the sled body; Step 2. Clamp the reinforcing rib plate to be welded between the corresponding clamping plate and the inner wall of the reinforcing rib clamp block, and fix it by a reset spring, and rotate the reinforcing rib clamp block so that the damping rotator damps the rotation; Step 3. Pull the control handle to lift the clamping block and compress the clamping spring, separate the clamping block from the friction outer ring, slide and rotate the positioning adjuster, adjust the reinforcing rib plate to the welding position of the sled body, and then release the control handle to press the clamping block against the friction outer ring to fix the positioning adjuster; Step 4. Weld the reinforcing rib plate to the main body of the sled board using welding equipment. After welding, remove the reinforcing rib clamp from the sled board.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention provides a reinforcing rib clamp, which can clamp and fix the reinforcing rib plate and adjust it to a suitable angle, so that the reinforcing rib plate is tilted and fits the main body of the sled board for easy welding.
