The end of the connecting rope 42 away from the positioning block 4 is fixedly connected to the upper end of the positioning pin 43.

[0035] The positioning block 4 is fixed to the surface of the welding table 1 with screws. The lower end of the positioning pin 43 is inserted into the insertion hole 41 to position the positioning pin 43, preventing it from falling onto the surface of the welding table 1. The positioning pin 43 is connected by the connecting rope 42 to prevent it from being lost. During use, the positioning pin 43 is used to quickly position the plate-shaped part 3 on the upper side of the first support block 12, the second support block 13, and the support rod 16. At the same time, the positioning pin 43 is used to quickly position the first part 31, the second part 32, and the third part 33 on the surface of the plate-shaped part 3. The hydraulic cylinder 21 drives the first pressure plate 24 and the second pressure plate 26 to move downwards, pressing and fixing the first part 31 and the second part 32, thereby improving the stability of the welding process.

[0036] See Figures 2 to 4The surface of the welding table 1 is fixedly connected to two sets of support frames 11, one on the left and one on the right. A first support block 12 is fixedly connected to the rear side of the upper surface of the support frame 11.

By passing screws through the connecting holes, the connecting block 23 and the connecting rod 22 can be fixed. At the same time, by passing screws through different connecting holes, the position of the connecting block 23 can be adjusted, thereby adjusting the position of the first pressure plate 24 and the second pressure plate 26, so as to press and fix the first part 31 and the second part 32 at different positions. During use, the telescopic rod in the hydraulic cylinder 21 drives the connecting rod 22 to move downward, thereby driving the first pressure plate 24 and the second pressure plate 26 to move downward, pressing and fixing the first part 31 and the second part 32 respectively.

[0038] Meanwhile, the surface of the third pressure plate 28 is also provided with a connecting hole, and the surface of the clamping block 27 is provided with a threaded hole. The screw passes through the connecting hole and the threaded hole to fix the third pressure plate 28 and the clamping block 27. At this time, the third pressure plate 28 will be clamped on the upper surface of the plate-shaped part 3 to press and fix the plate-shaped part 3, thereby improving the stability of the plate-shaped part 3 during the welding process.

[0039] See Figure 1 and Figure 5The lower surface of the plate-shaped part 3 is mounted on the upper side of the first support block 12, the second support block 13 and the support rod 16.

[0040] Specifically, during the part loading process, the third part 33 is first clamped onto the upper surfaces of the second support block 13 and the third support block 14, and the positioning pin 43 is inserted through the fourth positioning hole 35 on the surface of the third part 33 and the first positioning hole 15 on the surface of the third support block 14 to quickly position the third part 33. Then, the plate-shaped part 3 is placed on the upper side of the first support block 12, the second support block 13 and the support rod 16, and the positioning pin 43 is inserted through the third positioning hole 34 on the surface of the plate-shaped part 3, the first positioning hole 15 on the surface of the second support block 13 and the fourth positioning hole 35 on the surface of the third part 33 to quickly position the plate-shaped part 3. At the same time, the welding position between the third part 33 and the plate-shaped part 3 is quickly positioned. At this time, the third pressure plate 28 is used to press and fix the plate-shaped part 3, thereby increasing the tightness of the connection between the plate-shaped part 3 and the third part 33.

[0041] Next, the first part 31 and the second part 32 are erected on the front and rear sides of the plate-shaped part 3, respectively. The positioning pin 43 passes through the fourth positioning hole 35 on the lower side of the first part 31 and the second part 32 and the third positioning hole 34 on the surface of the plate-shaped part 3, quickly positioning the lower ends of the first part 31 and the second part 32 on the surface of the plate-shaped part 3. Then, the positioning pin 43 passes through the second positioning hole 25 on the surface of the first pressure plate 24 and the second pressure plate 26 and the fourth positioning hole 35 on the upper side of the first part 31 and the second part 32, positioning the upper ends of the first part 31 and the second part 32 with the first pressure plate 24 and the second pressure plate 26, respectively, improving the accuracy of the welding position. At the same time, the hydraulic cylinder 21 moves the first pressure plate 24 and the second pressure plate 26 downward, pressing the first part 31 and the second part 32 together, improving the stability of the welding process.

[0042] The working principle of this utility model is as follows: The positioning pin 43 passes through the third positioning hole 34 and the first positioning hole 15, quickly positioning the plate-shaped part 3 on the surface of the first support block 12, the second support block 13 and the support rod 16. At the same time, the positioning pin 43 passes through the fourth positioning hole 35 and the third positioning hole 34, quickly positioning the first part 31, the second part 32 and the third part 33 on the surface of the plate-shaped part 3. The first pressure plate 24 and the second pressure plate 26 are moved downward by the hydraulic cylinder 21 to press and fix the first part 31 and the second part 32, effectively improving the stability of the parts and the welding quality. At the same time, it is convenient to quickly position and disassemble the parts, effectively improving the welding efficiency.
