Description

Technical Field

[0001] This utility model relates to the field of truck component welding technology, and in particular to a support platform for spot welding of truck components. Background Technology

[0002] Guided by the dual carbon targets, my country's new energy heavy-duty truck market has entered a period of ultra-high-speed development. In the welding of vehicle parts, most of them are currently spot welding. Spot welding refers to the welding method that uses a columnar electrode to form a weld point between the contact surfaces of two overlapping workpieces. During spot welding, pressure is first applied to make the workpieces come into close contact, and then current is applied. Under the action of resistance heat, the contact area of ​​the workpieces melts and forms a weld point after cooling.

[0003] In existing technologies, when welding two overlapping workpieces, one operator first needs to lift the workpiece between the first and second electrodes of the spot welding machine, and then another operator operates the spot welding machine to weld the two overlapping workpieces. After completing one spot weld, it may be necessary to adjust the position of the two workpieces and repeat the spot welding operation until the desired result is achieved. Finally, the two welded workpieces are removed. The repeated adjustment of the workpiece position during welding places a heavy workload on the operators, is cumbersome, and has low processing efficiency. Therefore, this utility model proposes a support platform for spot welding truck parts to solve the above problems. Utility Model Content

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a support platform for spot welding truck parts, including a workbench 1, a fixed base 2, an intermediate plate 3, and spot welding seats 4. The workbench 1 is provided with a fixed base 2 on its top, and an intermediate plate 3 is fixedly connected to the middle of the fixed base 2. A set of spot welding seats 4 are symmetrically fixedly connected to both sides of the intermediate plate 3. The fixed base 2 is provided with a limiting mechanism. When two truck parts are placed on both sides of the fixed base 2, the limiting mechanism on the fixed base 2 can restrict the two truck parts to both sides of the fixed base 2, thereby locking the position of the truck parts and avoiding the problem that the workpiece position needs to be repeatedly adjusted during welding, which increases the workload of the operator, is cumbersome, and has low processing efficiency. At this time, the top of the spot welding seat 4 is located below the spot welding hole of the truck part.

[0020] The limiting mechanism includes limiting rods 5, sliding plates 6, bidirectional lead screws 7, and a motor 8. Limiting rods 5 are symmetrically fixedly connected to both sides of the fixed base 2. Sliding plates 6 are symmetrically slidably connected to both ends of the limiting rods 5. The bidirectional lead screw 7 is rotatably connected to the top of the fixed base 2. Sliding plates 6 are symmetrically threaded to both ends of the bidirectional lead screw 7. The motor 8 is fixedly connected to one side of the fixed base 2. The output end of the motor 8 is fixedly connected to one end of the bidirectional lead screw 7. The top of the spot welding seat 4 is located below the spot welding hole. The sliding plates 6 and the intermediate plate 3 are parallel to each other. The two clamps... The vehicle parts are placed on both sides of the fixed base 2. The output end of the motor 8 can drive the bidirectional lead screw 7 to rotate inside the fixed base 2. The bidirectional lead screw 7 is threadedly engaged with the sliding plate 6, and the limiting rod 5 can restrict the movement trajectory of the sliding plate 6. The bidirectional lead screw 7 can drive the two sliding plates 6 to move simultaneously in different directions. The sliding plates 6 can drive the truck parts to move towards the middle plate 3. The sliding plates 6 and the middle plate 3 cooperate to limit the position of the truck parts. At this time, the spot welding holes on the truck parts are vertically parallel to the position of the spot welding seat 4 to lock the position of the truck parts and avoid repeated adjustments of the truck parts.

[0021] The workbench 1 is equipped with a self-locking motor. A rotating shaft is rotatably connected to the top of the workbench 1. The top of the rotating shaft is fixedly connected to the bottom of the fixed base 2. The top of the workbench 1 is equipped with a rotating mechanism, which includes a second gear 10 and a first gear 9. The second gear 10 is rotatably connected to one side of the top of the workbench 1. The first gear 9 is fixedly connected to the outside of the rotating shaft. The top of the first gear 9 is fixedly connected to the bottom of the fixed base 2. The outer walls of the second gear 10 and the first gear 9 mesh with each other. The output end of the self-locking motor is fixedly connected to the bottom end of the second gear 10. The output end of the self-locking motor can drive the second gear 10 to rotate. The second gear 10 and the first gear 9 mesh with each other, and the first gear 9 is also connected to the fixed base 2 as a whole. The self-locking motor can drive the fixed base 2 to rotate and then self-lock, so as to automatically adjust the position of the truck parts on the fixed base 2.

[0022] The fixed base 2 has a protective shell on one side, the motor 8 is wrapped inside the protective shell, and multiple anti-collision strips are provided on the outside of the protective shell. The protective shell and anti-collision strips can isolate the motor 8 from external objects, prevent external objects from directly contacting the motor 8, and protect the motor 8.

[0023] A set of fixed sleeves 11 are symmetrically fixedly connected to both sides of the workbench 1. A sliding rod 12 is slidably connected to the top of the fixed sleeve 11. An end cap 13 is fixedly connected to the top of the sliding rod 12. A damping pad 15 is fixedly connected to the bottom of the sliding rod 12. The outer wall of the damping pad 15 is in close contact with the inner wall of the fixed sleeve 11. A spring 14 is provided on the outer side of the sliding rod 12. When the spot welding machine moves downward, it will contact the end cap 13. The spot welding machine squeezes the sliding rod 12 downward through the end cap 13, so that the damping pad 15 at the bottom of the sliding rod 12 rubs against the inner wall of the fixed sleeve 11. The friction generated can consume the pressure generated by the sliding rod 12, and the spring 14 is in a compressed state. After the welding machine moves upward, the elastic force generated by the spring 14 drives the sliding rod 12 to move upward and reset.

[0024] The support platform for spot welding truck parts places two truck parts on both sides of the fixed base 2. The output end of the motor 8 can drive the bidirectional lead screw 7 to rotate inside the fixed base 2. The bidirectional lead screw 7 is threadedly engaged with the sliding plate 6, and the limiting rod 5 can restrict the movement trajectory of the sliding plate 6. The bidirectional lead screw 7 can drive the two sliding plates 6 to move simultaneously in different directions. The sliding plates 6 can drive the truck parts to move towards the middle plate 3. The sliding plates 6 and the middle plate 3 cooperate to limit the position of the truck parts. At this time, the spot welding holes on the truck parts are vertically parallel to the position of the spot welding seat 4 to lock the position of the truck parts and avoid repeated adjustments of the truck parts.
