Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings Figures 1-5 , and it is obvious that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0022] As shown in the figure, a stud welding machine includes a frame 1. A gantry 2 that can slide along the Y-axis is provided on the frame 1. Generally, the Y-axis sliding of the gantry 2 can be achieved by means of a lead screw drive. An X-axis moving pallet 3 that can slide in the X-axis direction is provided on the gantry 2. Generally, the X-axis sliding of the X-axis moving pallet 3 can be achieved by providing a horizontal linear module on the gantry 2 and arranging the X-axis moving pallet 3 on the sliding seat of the linear module. A plurality of slide table cylinders 5 whose sliding seats can slide in the Z-axis direction are provided on the X-axis moving pallet 3. A Z-axis moving pallet 4 is provided on the sliding seat of the slide table cylinder 5. A welding gun 6 is provided on the Z-axis moving pallet 4. By driving the Z-axis moving pallet 4 by the slide table cylinder 5 to drive the welding gun 6, the Z-axis movement of the welding gun 6 is realized. Through the above structure, the welding gun 6 can be driven to move in the three directions of the X, Y, and Z axes to realize the position adjustment of the welding gun 6 during stud welding operations. A protective cover 7 with upper and rear ends open and covering the slide table cylinder 5 and the welding gun 6 is fixedly connected to the X-axis moving pallet 3. Specifically, the protective cover 7 is fixedly connected to the X-axis moving pallet 3 by fixing its side plates to the side ends of the X-axis moving pallet 3. A first through hole 71 and a second through hole 72 through which the sliding seat of the slide table cylinder 5 and the welding gun 6 can pass respectively are provided on the bottom plate of the protective cover 7. A pipe passing opening 73 is provided on the front side plate of the protective cover 7. The pipe passing opening 73 is used for the feed pipe of an external feeding device to penetrate into the protective cover 7 and be connected to the feed pipe of the welding gun 6. When this stud welding machine performs stud welding operations, when the welding gun 6 moves to above the welding point through the movement in the X-axis and Y-axis directions, the slide table cylinder 5 drives the welding gun 6 to move downward so that the stud fed into the welding gun 6 abuts against the workpiece for welding. During the downward movement of the welding gun 6, the first through hole 71 and the second through hole 72 are used for the sliding seat of the slide table cylinder 5 and the welding gun 6 to pass through to realize the downward movement of the welding gun 6. During the welding process, the protective cover 7 plays a role in blocking the sparks and debris generated during welding, reducing the direct fall of the sparks and debris onto components such as the driving cylinder, slide table cylinder 5, and the connecting air pipe of the slide table cylinder 5 at the upper end of the welding gun 6 located inside the protective cover 7, preventing damage to the above components, and also ensuring the stability and accuracy of the above components when driving the welding gun 6 to perform Z-axis movement, thereby ensuring the stability during welding and the welding quality.

[0023] Additionally, a junction box 8 is fixedly connected to the upper end of the X-axis moving platen 3. A plurality of wire threading bellows 9 communicating with the interior of the junction box 8 are fixedly connected to the upper end of the junction box 8. A support plate 10 is fixedly connected to the upper end of the Z-axis moving platen 4. The other end of the wire threading bellows 9 is fixedly connected to the support plate 10 opposite to the upper opening of the protective cover 7. In the above structure, the electrode wiring of the welding torch 6, the air supply pipes of the driving cylinder of the welding torch 6, and the air supply pipes of the sliding table cylinder 5 penetrate into the junction box 8 and then pass through the wire threading bellows and penetrate into the protective cover 7 to be connected to the welding torch 6 or the sliding table cylinder 5, so that the above pipelines are sectionally bundled in the protective cover 7, the wire threading bellows 9, and the junction box 8, avoiding the direct fall of the sparks generated during welding onto the above pipelines to cause damage, playing a protective role for the pipelines, and also facilitating the routing arrangement of the above pipelines and subsequent maintenance.

[0024] Additionally, a wire bundling plate 11 is fixedly connected to the Z-axis moving platen 4 on one side above the welding torch 6. A wire bundling groove 111 aligned with the port of the wire threading bellows 9 is formed on the wire bundling plate 11. In the above structure, the electrode wiring of the welding torch 6 and the air supply pipes of the driving cylinder of the welding torch 6 pass through the wire bundling groove 111 and then penetrate into the wire threading bellows, so that the above pipelines are bundled in the wire bundling groove, thereby ensuring that the above pipelines can be stably maintained in the protective cover 7 and protected by the protective cover 7.

[0025] Additionally, a plurality of heat dissipation holes 74 are formed on the left and right side plates of the protective cover 7. The heat dissipation holes 74 strengthen the air flow in the horizontal direction inside the protective cover 7, which is beneficial to the heat dissipation of the welding torch 6 and the sliding table cylinder 5 inside the protective cover 7 during welding operations.

[0026] Additionally, a Z-axis induction piece 12 is fixedly connected to the side end of the Z-axis moving platen 4. A Z-axis sensor 13 is arranged on the X-axis moving platen 3 on the moving path of the Z-axis induction piece 12. In the above structure, through the cooperation of the Z-axis induction piece 12 and the Z-axis sensor 13, the position of the welding torch 6 moving on the Z-axis is monitored, ensuring that after the welding of the previous stud is completed and the welding torch 6 is fully reset, the feeding device conveys the next stud into the welding torch 6, thereby ensuring the orderly progress of the welding operation.

[0027] Additionally, an X-axis induction piece 14 is fixedly connected to the lower end of the X-axis moving platen 3. An X-axis sensor 15 is arranged on the gantry 2 on the moving path of the X-axis induction piece 14. Two X-axis sensors 15 are arranged on both sides of the X-axis induction piece 14 respectively. In the above structure, through the cooperation of the X-axis induction piece 14 and the X-axis sensor 15, the position of the X-axis moving platen 3 moving on the X-axis is monitored, restricting the moving stroke of the X-axis moving platen 3 on the X-axis between the two X-axis sensors 15, preventing the X-axis moving platen 3 from moving excessively and colliding with other components, thereby ensuring the orderly progress of the welding operation.

[0028] Additionally, an adjustment groove 21 that is along the X-axis direction and has a T-shaped cross-section is formed on the gantry 2. An adjustment bolt 151 is passed through the X-axis sensor 15, and the adjustment bolt 151 is screwed into an adjustment nut provided in the adjustment groove 21 after passing through the adjustment groove 21. In the above structure, by loosening the adjustment bolt 151, the X-axis sensor 15 can be toggled to move along the adjustment, and the distance between the two X-axis sensors 15 can be adjusted, that is, the moving stroke of the X-axis moving support plate 3 can be adjusted to meet the processing requirements of workpieces of different sizes.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
