Description

Technical Field

[0001] This utility model relates to the field of weld point grinding technology, specifically to a weld point grinding and trimming device for laser welding. Background Technology

[0002] In daily production, in order to improve the appearance of the product and remove the defects left during the welding process, it is necessary to grind the product to remove the burrs and weld beads left over from the welding process.

[0003] A search revealed a Chinese patent publication dated August 4, 2023, with publication number CN219465702U, describing a laser welding spot grinding and trimming device. The device generally includes a base with a placement groove containing a lead screw. The left end of the lead screw passes through the base and can rotate relative to it. A motor A is fixedly mounted on the left end of the base, with its output end fixed to the lead screw. Two supports are located above the base and are fixed together by a connecting plate. Support rods are fixedly mounted on the right ends of each support. Both supports can slide left and right relative to the base. Rotation of the lead screw drives the base to move. A rotating wheel is located between the upper ends of the two support rods, with rotating shafts fixedly mounted on both the front and rear sides of the wheel.

[0004] Although the existing technical solution described above can adjust the grinding device, the position of the support plate of the device is relatively fixed, which makes it inconvenient for the grinding wheel set to grind different positions of the workpiece, thus reducing the applicability of the equipment.

A fixed frame is fixedly connected to the top of the base, and a rotating rod is rotatably connected to the inner side wall of the fixed frame. A mounting plate is fixedly connected to the rotating rod, and a first motor is mounted on one end of the mounting plate. The output end of the first motor passes through the mounting plate and is connected to a grinding wheel assembly. A first control groove is provided at the top of the base, and a first threaded rod is rotatably connected inside the first control groove. One end of the first threaded rod passes through the first control groove and is connected to a first rotating handle. A first threaded component is threadedly connected to the first threaded rod.

[0009] By adopting the above technical solution, the workpiece is placed on the placement seat, and the first motor is started to drive the grinding wheel set to rotate. The rotating mounting plate drives the grinding wheel set to rotate, so that the grinding wheel set is close to the workpiece, thereby enabling the equipment to grind the workpiece. Rotating the first rotating handle drives the first threaded rod to rotate, the first threaded rod drives the first threaded component to move, the first threaded component drives the U-shaped moving seat and the placement seat to move, thereby causing the workpiece to move left and right. Rotating the second rotating handle drives the second threaded rod to rotate, the second threaded rod drives the second threaded component to move, the second threaded component drives the placement seat to move back and forth, thereby causing the workpiece to move back and forth. This facilitates the grinding wheel set to grind different positions of the workpiece, improving the applicability of the equipment.

The two clamping plates cooperate to clamp and fix the workpiece, thereby facilitating the equipment to grind the workpiece.

[0012] Optionally, both clamping plates have a cushioning pad at one end close to the other.

[0013] By adopting the above technical solution, the buffer pad is used to provide cushioning between the clamping plate and the workpiece, so as to avoid the clamping plate from causing damage to the workpiece.

[0014] Optionally, both ends of the two clamping plates are fixedly connected with inclined baffles.

[0015] By adopting the above technical solution, the inclined baffle is used to block and stop the side of the workpiece when the equipment clamps the workpiece, so as to prevent the workpiece from tipping over when subjected to external force, thereby improving the stability of the equipment.

At this time, it is convenient for personnel to adjust the position of the workpiece. When the position of the workpiece is adjusted, the mounting plate can be rotated to drive the grinding wheel set to move, so that the grinding wheel set can grind the workpiece.

[0020] Optionally, the fixing frame has a circular groove inside, and a threaded hole is formed on the upper inner side wall of the circular groove.

[0021] By adopting the above technical solution, when a point on the workpiece needs to be ground for a long time, the rotating mounting plate drives the grinding wheel set to contact the point on the workpiece to be ground. Then, the rotating control bolt drives the arc-shaped gear to move, so that the arc-shaped gear meshes with the gear. This positions the gear, rotating rod and mounting plate, thereby positioning the grinding wheel set and facilitating the equipment to grind the workpiece locally for a long time.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Reference Figures 1-4A laser welding spot grinding and finishing device includes a base 1 and a U-shaped movable seat 2. A fixed frame 3 is fixedly connected to the top of the base 1. A rotating rod 4 is rotatably connected to the inner side wall of the fixed frame 3. A mounting plate 5 is fixedly connected to the rotating rod 4. A first motor 6 is mounted on one end of the mounting plate 5. The output end of the first motor 6 passes through the mounting plate 5 and is connected to a grinding wheel set 7. A first control groove is opened at the top of the base 1. A first threaded rod 8 is rotatably connected inside the first control groove. One end of the first threaded rod 8 passes through the first control groove and is connected to a first rotating handle 9. A first threaded component 10 is threadedly connected to the first threaded rod 8. The U-shaped movable seat 2 is fixedly connected to the top of the first threaded component 10. A placement seat 11 is slidably connected to the inner side wall of the U-shaped movable seat 2. A second control groove is opened at the top of the U-shaped movable seat 2. A second threaded rod 12 is rotatably connected inside the second control groove. One end of the second threaded rod 12 passes through the second control groove. The groove is connected to a second rotating handle 13, and a second threaded part 14 is threadedly connected to the second threaded rod 12. The top end of the second threaded part 14 is connected to the placement seat 11. The workpiece is placed on the placement seat 11, and the first motor 6 is started to drive the grinding wheel set 7 to rotate. The rotating mounting plate 5 drives the grinding wheel set 7 to rotate, so that the grinding wheel set 7 is close to the workpiece, thereby enabling the equipment to grind the workpiece. Rotating the first rotating handle 9 drives the first threaded rod 8 to rotate, and the first threaded rod 8 drives the first threaded part 10 to move. The first threaded part 10 drives the U-shaped moving seat 2 and the placement seat 11 to move, thereby causing the workpiece to move left and right. Rotating the second rotating handle 13 drives the second threaded rod 12 to rotate, and the second threaded rod 12 drives the second threaded part 14 to move. The second threaded part 14 drives the placement seat 11 to move back and forth, thereby causing the workpiece to move back and forth. This makes it easier for the grinding wheel set 7 to grind different positions of the workpiece, improving the applicability of the equipment.

[0033] Reference Figure 3 and Figure 4 The top of the placement seat 11 is provided with a third control groove. A bidirectional threaded rod 15 is rotatably connected inside the third control groove. Two mating third threaded parts 16 are threadedly connected to the bidirectional threaded rod 15. The tops of the two third threaded parts 16 pass through the third control groove and are connected to clamping plates 17. A second motor 18 connected to the bidirectional threaded rod 15 is installed on the outer wall of the placement seat 11. When the workpiece is placed on the placement seat 11, the second motor 18 is started to drive the bidirectional threaded rod 15 to rotate. The bidirectional threaded rod 15 drives the two third threaded parts 16 to move. The third threaded parts 16 drive the clamping plates 17 to move. The two clamping plates 17 cooperate to clamp and fix the workpiece, thereby facilitating the grinding of the workpiece by the equipment.

[0034] Reference Figure 1 Both clamping plates 17 have a buffer pad 19 at one end close to each other. The buffer pad 19 is used to provide cushioning between the clamping plate 17 and the workpiece to avoid the clamping plate 17 from damaging the workpiece.

[0035] Reference Figure 1 Both ends of the two clamping plates 17 are fixedly connected with inclined baffles 20. The inclined baffles 20 are used to block and stop the side of the workpiece when the equipment clamps the workpiece, so as to prevent the workpiece from tipping over when subjected to external force, thereby improving the stability of the equipment.

[0036] Reference Figures 1-4 The top of the base 1 has two corresponding limiting grooves 21. The bottom of the U-shaped moving seat 2 is fixedly connected to two limiting sliders 22 that are slidably connected to the limiting grooves 21. The limiting grooves 21 and the limiting sliders 22 cooperate to limit the U-shaped moving seat 2, so that the U-shaped moving seat 2 is prevented from deflecting when it moves, thereby facilitating the equipment to perform precise processing on the workpiece.

[0037] Reference Figure 2 One end of the mounting plate 5 is fixedly connected to a connecting rod 23. A tension spring 24 is provided between the connecting plate and the base 1. When the equipment is not in use and the position of the workpiece needs to be adjusted, the tension spring 24 drives the connecting rod 23 to move, thereby driving the mounting plate 5 and the rotating rod 4 to rotate, thereby driving the grinding wheel set 7 away from the workpiece. At this time, it is convenient for personnel to adjust the position of the workpiece. When the position of the workpiece is adjusted, the mounting plate 5 can be rotated to drive the grinding wheel set 7 to move, so that the grinding wheel set 7 can grind the workpiece.

[0038] Reference Figure 3 The fixed frame 3 has a circular groove inside, and a threaded hole is formed on the upper inner side wall of the circular groove. A control bolt 25 is threadedly connected inside the threaded hole. An arc-shaped toothed piece 26 is rotatably connected to the bottom end of the control bolt 25. A gear 27 that is rotatably connected to the circular groove is fixedly connected to the rotating rod 4. The gear 27 and the arc-shaped toothed piece 26 cooperate. When it is necessary to grind a point on the workpiece for a long time, the rotating mounting plate 5 drives the grinding wheel set 7 to contact the point on the workpiece to be ground. Then, the rotating control bolt 25 drives the arc-shaped toothed piece 26 to move, so that the arc-shaped toothed piece 26 meshes with the gear 27. This positions the gear 27, the rotating rod 4 and the mounting plate 5, thereby positioning the grinding wheel set 7 and facilitating the equipment to grind a local part of the workpiece for a long time.

[0039] In summary, the working principle and process of this laser welding spot grinding and finishing device are as follows: First, the workpiece is placed on the placement seat 11. The first motor 6 is started, driving the grinding wheel assembly 7 to rotate. The rotating mounting plate 5 drives the grinding wheel assembly 7 to rotate, bringing it close to the workpiece, thus allowing the equipment to grind the workpiece. Rotating the first rotating handle 9 drives the first threaded rod 8 to rotate, which in turn moves the first threaded component 10. The first threaded component 10 then moves the U-shaped moving seat 2 and the placement seat 11, thus moving the workpiece left and right. Rotating the second rotating handle 13 drives the second threaded rod 12 to rotate, which in turn moves the first threaded component 10... The second threaded component 14 moves, driving the placement seat 11 to move back and forth, thereby moving the workpiece back and forth. This facilitates the grinding wheel assembly 7 to grind different positions on the workpiece, improving the applicability of the equipment. When the workpiece is placed on the placement seat 11, the second motor 18 is started to drive the bidirectional threaded rod 15 to rotate. The bidirectional threaded rod 15 drives the two third threaded components 16 to move, and the third threaded components 16 drive the clamping plate 17 to move. The two clamping plates 17 cooperate to clamp and fix the workpiece, facilitating the grinding of the workpiece by the equipment. The buffer pad 19 is used to provide cushioning between the clamping plate 17 and the workpiece, avoiding the clamping plate 17 from moving back and forth. 7. To prevent workpiece damage, the inclined baffle 20 is used to block and stop the workpiece from tilting when it is clamped by the equipment, thereby improving the stability of the equipment. The limiting groove 21 cooperates with the limiting slider 22 to limit the U-shaped moving seat 2, so that the U-shaped moving seat 2 does not tilt when it moves, thus facilitating the precise processing of the workpiece by the equipment. When the equipment is not in use and the position of the workpiece needs to be adjusted, the tension spring 24 drives the connecting rod 23 to move, thereby driving the mounting plate 5 and the rotating rod 4 to rotate. This moves the grinding wheel assembly 7 away from the workpiece, making it easier for personnel to adjust the workpiece's position. Once the workpiece position is adjusted, the mounting plate 5 can be rotated to move the grinding wheel assembly 7, allowing it to grind the workpiece. When a point on the workpiece needs to be ground for an extended period, the mounting plate 5 is rotated to bring the grinding wheel assembly 7 into contact with the point to be ground. Then, the control bolt 25 is rotated to move the arc-shaped gear 26, causing it to mesh with the gear 27. This positions the gear 27, the rotating rod 4, and the mounting plate 5, thus positioning the grinding wheel assembly 7 and facilitating long-term grinding of a specific area of ​​the workpiece.

[0040] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
