[0002] The internal structure of an underground trash bin is generally a three-dimensional frame. Currently, the frame welding method involves measuring the distance first, placing the workpiece to be welded in the measured position, welding, and then measuring the error (if the error is large, it needs to be cut and re-welded; if the error is slightly large, it needs to be corrected). Vertical welding of workpieces requires the cooperation of two people, one of whom needs to straighten the vertical workpiece to prevent it from falling over; and the subsequent welding may also cause the previously welded frame to deform, so it is necessary to weld, measure, and correct at the same time. This results in low welding efficiency, heavy workload, and large errors. Summary of the Invention

DETAILED DESCRIPTION

[0017] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0018] In this utility model, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 For example, the positional relationships of front, back, up, down, left, and right are determined according to the layout directions of the drawings in the specification.

[0019] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0020] Example 1: As shown in the attached Figure 1-4 As shown, the underground garbage bin welding tooling includes an inverted T-shaped support body, which includes a bottom support frame 1 and a vertical support frame 2. The vertical support frame 2 is installed on the upper side of the bottom support frame 1. The vertical support frame 2 divides the bottom support frame 1 into two parts, front and back. The front part is the inner box tooling, and the rear part is the outer box tooling. The inner box tooling and the outer box tooling both include a positioning support frame 3 installed on the upper side of the bottom support frame 1. The frame structure of the two positioning support frames 3 matches the inner box and outer box structures. The front and rear sides of the cross bars in the positioning support frames 3 are both installed with limiting plates 4 at intervals on the left and right sides, and the left and right sides of the longitudinal bars in the positioning support frames 3 are both installed with limiting plates 4 at intervals on the front and back. The inner box tooling and the outer box tooling also include upper support rods 5. At least two upper support rods 5 are installed at intervals on the left and right sides of the front or rear side of the vertical support frame 2. Positioning blocks can be installed on the vertical support frames 2 and the upper support rods 5 according to the shape and position of the workpiece.

[0021] When welding, taking the inner box frame as an example, first, place the rear end cross tube and the front end cross tube of the lower end frame on the upper side of the positioning support frame 3, and clamp them between the limit plates 4. The limit plates 4 limit the front and rear directions of the cross tubes, and the upper side of the positioning support frame 3 limits the lower side of the cross tubes. The left and right ends of the cross tubes can be limited by setting positioning blocks on the positioning support frame 3. Therefore, the six directions of the up and down, left and right, and front and back of the cross tubes are restricted. Positioning can be achieved by placing the cross tubes in the specified position without measuring the placement position. Then, the left and right longitudinal tubes of the lower end frame are placed in the specified position, and the rear end cross tube and the front The end transverse tube limits the front and rear directions of the left and right longitudinal tubes, and the limiting plate 4 limits their left and right positions. Then the transverse tube and longitudinal tube inside the lower end frame are placed in turn. The workpieces, the workpieces and the limiting plate 4, and the positioning blocks are pressed against each other to correct possible deformation of the tubes themselves. After the tubes of the lower end frame are placed, when welding, first weld the left and right ends of the rear end transverse tube and the front end transverse tube to their left and right limit points, and then spot weld each end of the workpiece to prevent welding stress from being transformed, and then weld the vertical tubes and the top frame on the upper side of the lower end frame in turn. The upper support rod 5 is used to support the top frame. After all welding is completed, the left and right ends of the rear end cross tube and the front end cross tube and the left and right limit points are cut, the frame is hoisted upward to make its lower end frame and the top frame disengage from the limit plate 4 limit, and then the frame is moved forward to make its vertical pipe disengage from the left and right and rear limit, and then moved to the right and then moved forward to avoid the tooling frame and the frame can be taken out, and after taking out, the frame fixed by the tooling spot welding will be uniformly reinforced on the parts that need to be welded, the workpiece is fixed by tooling first spot welding, and then hoisted down to uniformly reinforce the parts that need to be welded, and then the middle of the rear end cross tube and the front end cross tube are cut, and the rear end cross tube and the front end cross tube are welded into a whole pipe, and cutting is done again after welding to reduce welding deformation. The utility model can accurately position each workpiece of the inner box tooling and the outer box tooling of the buried garbage bin, reduce position measurement, have small error, do not need frequent positioning and correction, and the limit plate 4 and the positioning block can support the workpiece, reduce welding deformation, have high welding efficiency, and the welding tool can be used many times and regularly calibrated.

[0022] The above-mentioned underground garbage bin welding tooling can be further optimized and / or improved according to actual needs:

[0023] Example 2: As shown in the attached Figure 1 、 2As shown, the inner box tooling positioning blocks include a first positioning block 6, a second positioning block 7, and a third positioning block 8. The first positioning block 6 is fixedly mounted on the inner box tooling; a back rod 11 is mounted on the left side of the upper support rod 5, and the second positioning block 7 is mounted on the front side of the left end of the back rod 11; a third positioning block 8 is mounted on the back rod 11 between the second positioning block 7 and the upper support rod 5, and there are gaps between the left side of the third positioning block 8 and the second positioning block 7, and between the right side of the third positioning block 8 and the left side of the upper support rod 5. The two gaps are used to place vertical workpieces. The length of the third positioning block 8 is the spacing between the workpieces in the two gaps. The outer box tooling positioning blocks are of the same type as the inner box tooling positioning blocks, and the positioning blocks are selected according to the frame structure.

[0024] The corresponding positioning blocks are set according to the position of the workpiece. The first positioning block 6 is directly installed on the inner box tooling, for example, fixed on the upper side of the upper support rod 5, which can locate the front and rear positions of the crossbar in the top frame. The second positioning block 7 is installed on the front side of the left end of the back rod 11, which can be used to fix and limit a single vertical pipe. The third positioning block 8 is used for two vertical pipes that are close to each other. The two vertical pipes are respectively clamped in the gap between the left side of the third positioning block 8 and the second positioning block 7, and between the right side of the third positioning block 8 and the left side of the upper support rod 5. The distance between the two vertical pipes is positioned by the third positioning block 8 without separate measurement. Therefore, the first positioning block 6, the second positioning block 7, and the third positioning block 8 can be used for workpieces in different installation situations to meet positioning requirements. According to needs, a crossbar can be set on the lower side of the upper support rod 5, and positioning blocks can be installed on the crossbar to fix the lower part of the vertical rod to enhance the anti-deformation ability.

[0025] Example 3: As shown in the attached Figure 3 As shown, the side of the positioning block is provided with a magnet 9 by a stud bolt. By arranging the magnet 9, the workpiece can be adsorbed to avoid the vertical rod workpiece from toppling over, and the collaboration of two people is not required.

[0026] Example 4: As shown in the attached Figure 1 、 2 As shown, the positioning support frame 3 further includes a spacer 10, which is installed at intervals on the upper side of the positioning support frame 3. The spacer 10 can be used to level the positioning support frame 3 and to cushion the lower end frame to create a gap between it and the positioning support frame 3, thereby preventing impurities or welding slag from falling from the positioning support frame 3 and affecting the leveling. If there are impurities or welding slag on the spacer 10, only the spacer 10 needs to be cleaned, reducing the frequency and time of cleaning.

[0027] Example 5: As shown in the attached Figure 1 、 2 As shown, positioning blocks are installed on the upper sides of the four corners of the positioning support frame 3. The positioning blocks at the four corners can be spot welded to the pipe fittings to prevent welding stress from being deformed.

[0028] Example 6: As shown in the attached Figure 1 、 2As shown, a reinforcing rod 12 is also included. A reinforcing rod 12 is installed between the vertical support frame 2 and the bottom support frame 1, and a reinforcing rod 12 is installed under the upper support rod 5. The reinforcing rod 12 is provided to strengthen the overall strength of the tooling and increase its service life.

[0029] The above technical features respectively constitute the various embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
