[0001] The present invention relates to the technical field of clamping components for welding, and specifically to a new type of welding fixture device for automotive cargo box parts. Background Technique
[0002] The automotive cargo box is a key part of the vehicle for carrying goods. Due to different vehicle models and uses, there are differences in design and size. The cargo boxes of light trucks are generally more compact, convenient for urban logistics distribution, and can flexibly shuttle through streets and alleys. The cargo boxes of medium trucks are larger in size and have a considerable volume, suitable for medium and long-distance batch transportation. The cargo boxes of heavy trucks are extremely long and wide, capable of carrying dozens of tons of goods, and play an important role in the transportation of large-scale engineering materials. Common materials for cargo boxes include steel, aluminum alloy, etc. Steel is strong and durable, while aluminum alloy can reduce the vehicle body weight and improve fuel economy. The patent application with the publication number CN220560763U discloses a new type of welding fixture device for automotive cargo box parts, including a main body. A welding clamping mechanism is arranged on the top of the main body, and a cleaning mechanism is arranged on the top of the main body. The welding clamping mechanism includes an adjusting component and a clamping component. The adjusting component is arranged on the top of the main body, and the clamping component is arranged on the surface of the adjusting component. The cleaning mechanism includes a cleaning component, and the cleaning component is arranged on the top of the main body. The adjusting component includes a telescopic column. The four peripheries of the bottom of the main body are fixedly connected with support frames, and the telescopic column is fixedly connected to the top of the main body. The clamping component includes a fixed block, and the cleaning component includes a baffle plate. The baffle plate is fixedly connected to the top of the main body. This device can quickly... The above patent clamps the parts with good clamping effect, and the parts are not easy to fall off, which improves the working efficiency. However, during the welding process of the automotive cargo box, due to the different shapes of the parts of the cargo box, traditional welding fixtures cannot firmly clamp them. Summary of the Invention
[0003] Aiming at the deficiencies of the prior art, the present invention provides a new type of welding fixture device for automotive cargo box parts to solve the problems raised in the above background technique.
[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A new type of welding fixture device for automotive cargo box parts, including a temporary storage box. A support leg is fixedly connected to the inner bottom of the temporary storage box, a placement plate is fixedly connected to the top of the support leg, and a clamping mechanism is fixedly connected to the outer wall of the placement plate. The clamping mechanism includes: Bearing seat, the bearing seat is fixedly connected to the top of the placement plate. Place the automotive cargo box parts to be welded at the position between the two bevel blocks. At this time, manually rotate the second bolt. The end of the second bolt rotates with the bearing seat, thereby restricting the position of the second bolt. The second bolt is threadedly connected to the bevel block, thereby driving the two bevel blocks to approach the parts, thereby clamping them and initially positioning the parts first. First bolt, the first bolt is rotatably connected to the outer wall of the bearing seat; Bevel block, the bevel block is threadedly connected to the first bolt. The adjustable clamping mechanism is designed. The threaded fit between the bevel block and the first bolt realizes the adjustment of the distance between the two bevel blocks, which can be compatible with different sizes of parts. At the same time, the surface of the fitting block is provided with a convex structure, which automatically fits into the concave part of the part under the action of the spring. Combined with the secondary limit of the fitting plate, it effectively solves the problem that the traditional fixture does not fit well when clamping special-shaped parts and improves the clamping stability. Stabilizing component, the outer wall of the bevel block is fixedly connected to the outer wall of the clamping mechanism. The stabilizing component drives the gear to mesh with the toothed plate through the motor, realizes the active advancement of the fitting plate, and cooperates with the elastic expansion and contraction of the limiting rod under the action of the spring to form a double limiting mode of "first flexible contact positioning + then rigid pressing". It can still maintain the clamping stability in the welding vibration environment and avoid the part offset caused by the rigid clamping of the traditional fixture.
[0005] Preferably, the outer walls of the bevel block and the temporary storage box are both provided with mutually limiting card slots.
[0006] Preferably, the stabilizing component includes a motor. The outer surface of the motor is fixedly connected to the outer wall of the bevel block. A gear is rotatably connected to the outer wall of the motor. A toothed plate is slidably connected to the outer wall of the bevel block. A start switch is provided on the motor. At this time, the motor is powered on and starts to drive the gear to rotate. The meshing connection between the gear and the toothed plate will drive the toothed plate to move towards the parts. At this time, under the extrusion of the fitting plate and the parts, the fitting block first contacts the parts. The fitting block is provided with a plurality of protrusions, which can then be pressed into the concave parts of the parts, thereby limiting the parts. The limiting rod can move in the limiting hole. Then, under the elasticity of the spring, the fitting block limits the parts, and then the fitting plate is pressed against the parts to limit the parts again.
[0007] Preferably, mutually limiting card slots are provided between the bevel block and the gear, and the gear is meshed with the toothed plate.
[0008] Preferably, a fitting plate is fixedly connected to the outer wall of the toothed plate. A limiting hole is provided on the outer wall of the fitting plate, and a limiting rod is inserted into the inner wall of the limiting hole.
[0009] Preferably, a spring is fixedly connected between the limiting rod and the fitting plate, and a fitting block is fixedly connected to the outer wall of the limiting rod.
[0010] Preferably, an auxiliary mechanism is fixedly connected to the outer wall of the temporary storage box. The linkage design of the fan and the air flow pipe in the auxiliary mechanism sprays air flow onto the parts during the welding process to accelerate heat dissipation, significantly reduce the temperature of the welding heat-affected zone, and inhibit the clamping looseness caused by the thermal expansion of the parts. At the same time, the adjustable sliding block drives the air flow pipe to move near the welding point through the second bolt, realizing directional and precise temperature reduction, and solving the problem of clamping failure caused by thermal deformation of traditional jigs.
[0011] Preferably, the auxiliary mechanism includes a bracket. The bracket is fixedly connected to the outer wall of the temporary storage box. A fan is fixedly connected to the outer wall of the bracket. A zigzag pipe is fixedly connected to the outer wall of the fan. The zigzag pipe is connected to the air flow pipe and the fan by an elastic material, keeping the air path unblocked when adjusting the position of the air flow pipe. The sprayed air flow can not only accelerate cooling but also directly blow the welding slag into the temporary storage box for collection, avoiding the influence of welding slag accumulation on the contact precision of the clamping surface of traditional jigs. At the same time, the integrated design reduces the space occupied by the equipment and improves the continuity of welding operations. The top of the zigzag pipe is fixedly connected to the air flow pipe. A sliding block is slidably connected to the outer wall of the bevel block. A second bolt is rotatably connected to the outer wall of the bevel block. Since the zigzag pipe is made of elastic material, the change in the position of the air flow pipe will not affect the position of the fan. The fan is powered on and starts to blow out air flow. Before welding, turn the second bolt. The end of the second bolt is rotatably connected to the outer wall of the bevel block, and the second bolt is threadedly connected to the sliding block, which will drive the movement of the position of the sliding block, and then move to the position where welding is required. During the welding process, the blowing of the air flow from the air flow pipe will accelerate the cooling of the parts, avoiding the influence of thermal expansion and contraction caused by parts welding on their clamping, and also cleaning the welding slag during the welding process and dropping it into the temporary storage box. The outer wall of the second bolt is threadedly connected to the sliding block, and the air flow pipe is fixedly connected to the outer wall of the sliding block.
[0012] Preferably, the outer walls of the bevel block and the sliding block are both provided with card slots that limit each other.
[0013] The present invention provides a new type of welding jig device for automobile cargo box parts. It has the following beneficial effects: 1. For this new type of welding jig device for automobile cargo box parts, through the design of an adjustable clamping mechanism, the threaded cooperation between the bevel block and the first bolt realizes the adjustment of the distance between the two bevel blocks, which can be compatible with parts of different sizes. At the same time, the surface of the fitting block is provided with a convex structure, which automatically fits into the recessed part of the part under the action of the spring. Combined with the secondary limitation of the fitting plate, it effectively solves the problem that traditional jigs do not fit well when clamping special-shaped parts, and improves the clamping stability.
[0014] 2. The welding fixture device for the new type of automobile cargo box parts realizes the active propulsion of the fitting plate through the stable component driving the gear to mesh with the toothed plate by the motor, and cooperates with the elastic expansion and contraction of the limiting rod under the action of the spring to form a double limiting mode of "first flexible contact positioning + then rigid pressing", which can still maintain the clamping stability under the welding vibration environment and avoid the part offset caused by rigid clamping of the traditional fixture.
[0015] 3. The welding fixture device for the new type of automobile cargo box parts, through the linkage design of the fan and the air flow pipe in the auxiliary mechanism, sprays air flow to the parts during the welding process to accelerate heat dissipation, significantly reduces the temperature of the welding heat affected zone, and inhibits the clamping looseness caused by the thermal expansion of the parts. At the same time, the adjustable sliding block drives the air flow pipe to move near the welding point through the second bolt to achieve directional and precise temperature reduction, solving the clamping failure problem caused by thermal deformation of the traditional fixture.
[0016] 4. The welding fixture device for the new type of automobile cargo box parts connects the fan and the air flow pipe with an elastic material through the zigzag pipe, keeps the air path unobstructed when adjusting the position of the air flow pipe, and the sprayed air flow can not only accelerate cooling but also directly blow the welding slag into the temporary storage box for collection, avoiding the influence of welding slag accumulation on the contact accuracy of the clamping surface of the traditional fixture. At the same time, the integrated design reduces the equipment occupation space and improves the continuity of the welding operation. BRIEF DESCRIPTION OF THE DRAWINGS
