Description

Technical Field

[0001] The utility model relates to the technical field of mechanical appliances, in particular to a welding tool used for offsetting thermal shrinkage deviation of slurry pipe welding. Background Art

[0002] The silicon wafers in photovoltaic modules are obtained by cutting silicon rods using multi-wire cutting equipment. During cutting, a liquid spraying device is required to spray coolant on the cutting wires to cool the cutting wires and flush out cutting waste. Therefore, multi-wire cutting equipment is usually equipped with a slurry pipe for spraying coolant. During the production of one type of grouting pipe, it is necessary to intermittently weld components such as bent plates, round tubes and V-shaped plates into one.

[0003] At present, a level ruler is usually used to ensure the flat surface of the slurry pipe during welding. However, uneven thermal shrinkage will still occur after welding, resulting in the final product not meeting the required size. In view of this, we propose a welding tool for offsetting the thermal shrinkage deviation of slurry pipe welding. Utility Model Content

[0006] As a further improvement of the present technical solution, the synchronous lifting assembly includes a linkage rod hinged on the side of the pressure plate away from the marble platform, and a plurality of the linkage rods are hinged at the lower ends with a movable plate. The side of the square rod away from the marble platform is fixedly connected with a sliding rod, and the movable plate is slidably sleeved on the outside of the sliding rod. The side wall of the movable plate is threadedly connected with a trapezoidal screw rod, and one end of the trapezoidal screw rod is rotatably connected to the base plate.

The plate 4 is clamped and fixed, the clamping mechanism 3 and the bent plate 4 are removed from the marble platform 1, the marble platform 1 is cleared, and then the arc mold 2 is placed on the upper surface of the marble platform 1. The upper surface of the arc mold 2 is an arc surface, and the bent plate 4 welded with the round tube 5 is placed on the arc surface of the arc mold 2, so that the highest point of the arc surface of the arc mold 2 is equal to the distance between the two ends of the bent plate 4. At this time, a 3mm gap is generated between the two ends of the bent plate 4 and the arc surface of the arc mold 2. The clamping mechanism 3 is used again to clamp the bent plate 4 at multiple points on the arc surface of the arc mold 2, so that the bent plate 4 is completely fitted with the arc surface of the arc mold 2 after bending, and then the V-shaped plate 6 is intermittently welded to the inside of the bent plate 4 to complete the work of welding the bent plate 4, the round tube 5 and the V-shaped plate 6 into one.

[0026] In order to enable the clamping mechanism 3 to clamp and fix the unbent bent plate 4 on the top of the marble platform 1, the structure of the clamping mechanism 3 is refined as follows: the clamping mechanism 3 includes a base plate 31 which is squeezed and matched with the lower surface of the marble platform 1; a plurality of square rods 32 are fixedly connected in a linear array on the upper surface of the base plate 31; a pressing plate 33 is provided on the sliding sleeve outside the square rod 32; a compensating bolt 34 is threadedly connected to the side wall of the pressing plate 33; the lower ends of the two outermost compensating bolts 34 are located below the lower ends of the other compensating bolts 34; a synchronous lifting assembly is provided on the base plate 31, and the synchronous lifting assembly is used to drive a plurality of pressing plates 33 to move vertically synchronously, refer to Figure 3 After placing the unbent bent plate 4 on the upper surface of the marble platform 1, move the bottom plate 31 to a position against the lower surface of the marble platform 1, so that the square rod 32 contacts the side of the marble platform 1 close to the arc mold 2. At this time, the compensation bolt 34 is located above the bent plate 4, and then the synchronous lifting assembly drives several pressing plates 33 to move vertically downward synchronously, and the pressing plates 33 drive several compensation bolts 34 to move downward synchronously until the two outermost compensation bolts 34 contact the upper surface of the bent plate 4 and squeeze the bent plate 4. The two outermost compensation bolts 34 cooperate with the bottom plate 31 to clamp the bent plate 4 on the upper surface of the marble platform 1, which is convenient for workers to intermittently weld the round tube 5 inside the bent plate 4.

[0027] Reference Figure 1 , in the process of clamping the bent plate 4 on the arc surface of the arc mold 2 at multiple points through the clamping mechanism 3, the arc mold 2 is first placed on the upper surface of the marble platform 1, and then the bent plates 4 are stacked and placed on the arc surface of the arc mold 2, and the bottom plate 31 is moved to a position where the upper surface of the marble platform 1 is against the square rod 32 and the side of the marble platform 1 close to the arc mold 2 is in contact. At this time, the compensation bolt 34 is located above the arc mold 2 and the bent plate 4, so that the synchronous lifting assembly drives a plurality of pressing plates 33 to move vertically downward synchronously, and the pressing plate 33 drives a plurality of compensation bolts 34 to move downward synchronously. After the two outermost compensation bolts 34 in the movement contact the upper surface of the bent plate 4, the bent plate 4 is squeezed and bent. When the pressing plate 33 continues to move downward until the lower ends of the plurality of compensation bolts 34 contact the arc surface of the bent plate 4, the lower surface of the bent plate 4 after extrusion and bending is completely attached to and fixed to the arc surface of the arc mold 2, which is convenient for workers to intermittently weld the V-shaped plate 6 to the inside of the bent plate 4. Figure 1 and Figure 4 The welding position of the V-shaped plate 6 in the bent plate 4 is located on the side of the compensation bolt 34 away from the square rod 32.

[0028] In order to drive several pressing plates 33 to move vertically synchronously, the structure of the synchronous lifting assembly is refined as follows. The synchronous lifting assembly includes a linkage rod 35 hinged on the side of the pressing plate 33 away from the marble platform 1, and a movable plate 37 is hinged at the lower end of the several linkage rods 35. The side of the square rod 32 away from the marble platform 1 is fixedly connected with a slide rod 36, and the movable plate 37 is slidably sleeved on the outside of the slide rod 36. The side wall of the movable plate 37 is threadedly connected with a trapezoidal screw rod 38, one end of the trapezoidal screw rod 38 is rotatably connected to the bottom plate 31, and the movable plate 37 is slidably connected to the upper surface of the bottom plate 31. The side of the bottom plate 31 away from the marble platform 1 is provided with an inner groove One end of the trapezoidal lead screw 38 is rotatably connected to the inner wall of the inner receiving groove, and the other end of the trapezoidal lead screw 38 is fixedly connected to a crank. When the worker holds the crank and turns the trapezoidal lead screw 38, the threaded connection between the trapezoidal lead screw 38 and the movable plate 37 is used to make the movable plate 37 move horizontally along the upper surface of the bottom plate 31. The moving movable plate 37 drives the pressure plate 33 to move vertically along the outer wall of the square rod 32 through the linkage rod 35, thereby driving several pressure plates 33 to move vertically synchronously. The self-locking fixing of the pressure plate 33 between the trapezoidal lead screw 38 and the movable plate 37 allows the pressure plate 33 to drive the compensation bolt 34 to clamp and fix the bent plate 4.

[0029] In summary, the working principle of this scheme is as follows: place the bent plate 4 on the upper surface of the marble platform 1, rotate the trapezoidal screw 38, so that the two outermost compensation bolts 34 clamp the bent plate 4 on the upper surface of the marble platform 1, and then intermittently weld the round tube 5 to the inside of the bent plate 4. After the welding point between the round tube 5 and the bent plate 4 is cooled, rotate the trapezoidal screw 38 in the opposite direction to release the clamping mechanism 3 from clamping the bent plate 4, remove the clamping mechanism 3 and the bent plate 4 from the marble platform 1, and empty the marble platform 1. , and then place the arc mold 2 on the upper surface of the marble platform 1, place the bent plate 4 welded with the round tube 5 on the arc surface of the arc mold 2, rotate the trapezoidal screw 38 again, and clamp the bent plate 4 on the arc surface of the arc mold 2 at multiple points through a number of compensation bolts 34, so that the bent plate 4 is bent and completely fits with the arc surface of the arc mold 2, and then the V-shaped plate 6 is intermittently welded inside the bent plate 4 to complete the work of welding the bent plate 4, the round tube 5 and the V-shaped plate 6 into one.
