Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to an assembly-type positioning device for a suspended spot welding machine. Background Technology

[0002] Suspension point welding uses medium-frequency inverter power supply technology, which can provide stable current output, ensure the firmness and consistency of the weld point, and meet the requirements of automotive suspension system for high-strength connection. By precisely controlling the current, pressure and time, the welding quality can be ensured and defects such as incomplete welds and porosity can be reduced. During welding, positioning fixtures are required to fix the parts to be welded to ensure the accuracy of the welding.

[0003] During plate welding, the existing positioning device first uses the pushing devices on both sides to adjust and center the position of the plate, and then uses the fixing device to fix the sides or four corners of the plate to complete the positioning of the plate. However, this fixing method has limited efficiency and requires two steps: pushing and centering, and four-corner positioning, making the positioning process relatively cumbersome.

[0008] Preferably, a flange bearing two is fixedly installed at the opening, the slide rod is slidably connected to the flange bearing two, and the return spring is used to push the plate placement platform upward.

[0009] Preferably, one side of the limiting clamp is an inclined surface, and both sides of the plate placement platform are inclined surfaces.

The lower end of the plate placement platform 9 is provided with a reset component that pushes the plate placement platform 9. The assembly positioning device of this suspension spot welding machine only requires placing the plate to be welded on the plate placement platform 9. Under the movement and pushing of the limiting clamp 8, the plate to be welded is automatically adjusted and fixed. After the plate is welded, the reset component makes the plate fall steadily to prevent collision and damage to the surface of the plate.

[0022] Please see Figure 1 , Figure 2 and Figure 4In this embodiment, one side of the limiting clamp 8 is an inclined surface, and both sides of the plate placement platform 9 are inclined surfaces. One inclined surface of the limiting clamp 8 contacts the side of the welded plate, and the inclined surface of the plate placement platform 9 contacts the lower end of the limiting clamp 8. A flange bearing 6 is fixedly installed on one side of the cylinder fixing plate 3. The flange bearing 6 is slidably connected to the output end of the standard cylinder 4. Fixed seats 17 are provided at both ends of the limiting frame 18. The limiting frame 18 is fixedly installed on the upper end of the base plate 1 through the base plate 1. An anti-slip pad 19 is fixedly connected to the lower end of the limiting frame 18. The anti-slip pad 19 contacts the upper end of the welded plate. The upper end of the base plate 1 is provided with... The plate has multiple sets of built-in threaded holes 20. These holes are used to install the mounting base 17. The limiting frame 18 and two limiting clamps 8 clamp and fix the plate to be welded. This fixing method is not only fast but also suitable for clamping and fixing plates. Simply place the plate on the plate placement platform 9, and the plate to be welded will automatically adjust and fix itself under the movement of the limiting clamps 8. This method is efficient and fast. The upper surface of the base plate 1 has multiple sets of built-in threaded holes 20. When welding plates of different lengths, the installation position of the limiting frame 18 can be adjusted to ensure that it is suitable for welding different types of plates.

[0023] Please see Figure 3 , Figure 5 and Figure 6 In this embodiment, the reset assembly includes a fixing base 10, which is fixedly installed at the lower end of the plate placement platform 9. A slide rod 11 is fixedly connected to the lower end of the fixing base 10. A locking block 12 is provided at the lower end of the slide rod 11. A reset spring 21 is sleeved on the surface of the slide rod 11. An opening is provided on the surface of the base plate 1, and the plate placement platform 9 is disposed in the opening on the surface of the base plate 1. A lower mounting plate 14 is provided at the lower end of the opening on the surface of the base plate 1. Fixing bases 16 are provided on both sides of the lower mounting plate 14. The lower mounting plate 14 is connected by... The second fixed base 16 is fixedly installed at the lower end of the base plate 1. The surface of the lower mounting plate 14 is provided with an opening 15. The slide rod 11 slides at the opening 15. The second flange bearing 13 is fixedly installed at the opening 15. The slide rod 11 is slidably connected to the second flange bearing 13. The return spring 21 is used to push the plate placement platform 9 upward. The slide rod 11 is used to prevent the return spring 21 from shifting when compressed. The second flange bearing 13 is used to ensure the stability of the slide rod 11 and ensure that the plate placement platform 9 descends smoothly. The locking block 12 is used for limiting.

[0024] In use, the workpiece to be welded is first placed on the upper end of the workpiece placement platform 9. Then, the standard cylinder 4 is activated, which pushes the limiting clamp 8 to move. During the movement of the limiting clamp 8, when the limiting clamp 8 moves to the inclined surfaces on both sides of the workpiece placement platform 9, the lower end of the limiting clamp 8 presses against the workpiece placement platform 9, causing the workpiece placement platform 9 to descend into the upper opening of the base plate 1. The workpiece to be welded falls between the two limiting clamps 8. Then, the two limiting clamps 8 continue to move, and the two sides of the workpiece to be welded contact the inclined surfaces of the limiting clamps 8. During the movement of the limiting clamps 8, one inclined surface of the limiting clamp 8 pushes the workpiece to be welded upward. The limiting frame 18 and the two limiting clamps 8 clamp and fix the workpiece to be welded. This fixing method is not only fast, but also suitable for clamping and fixing workpieces. Simply place the workpiece on the workpiece placement platform 9, and under the movement and pushing of the limiting clamps 8, the workpiece to be welded will automatically adjust and be fixed, which is efficient and fast.

[0025] Cylinder fixing plate 1 3 and cylinder fixing plate 2 5 are used to fix and install standard cylinder 4, flange bearing 1 6 is used to ensure the stability of movement of limit clamp 8, and connecting plate 7 is used to connect the output end of standard cylinder 4 and limit clamp 8.

[0026] The fixing base 17 is used to fix the limiting bracket 18. The anti-slip pad 19 at the lower end of the limiting bracket 18 is used to ensure the stability of the plate to be welded.

[0027] After welding is completed, the standard cylinder 4 is started again. The standard cylinder 4 drives the limit clamp 8 to move outward, and the plate descends. Under the push of the return spring 21, the plate placement platform 9 returns to its original position and contacts the lower end of the plate, thereby ensuring that the plate falls steadily after welding and preventing collisions that could damage the surface of the plate.

[0028] The fixed base 10 is used to fix the slide rod 11. The slide rod 11 slides at the opening 15 on the surface of the lower mounting plate 14. The slide rod 11 is used to prevent the return spring 21 from shifting when compressed. The flange bearing 13 is used to ensure the stability of the slide rod 11 and ensure the smooth descent of the plate placement platform 9. The locking block 12 is used for limiting.

[0029] The upper surface of the base plate 1 is provided with multiple sets of built-in threaded holes 20. When welding plates of different lengths, the installation position of the limit frame 18 can be adjusted to ensure that it is suitable for welding different types of plates.

[0030] Through the above steps, the assembly positioning device of the suspension spot welding machine only needs to place the plate to be welded on the plate placement platform 9. Under the movement and pushing of the limiting clamp 8, the plate to be welded is automatically adjusted and fixed. The pushing, centering and positioning are completed at the same time, which is efficient and fast. After the plate is welded, the reset component makes the plate fall steadily, preventing collisions that could damage the surface of the plate.
