[0025] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0026] Embodiment 1: Refer to Figure 3-11 , a welding tooling for an instrument bracket, which includes a tooling plate 1, two vertical rods 2, a pressure plate 3, a cylinder 4 and two positioning and pressing mechanisms 5.

[0027] Among them, refer to Figure 3-5 , the tooling plate 1 is used to horizontally support the main board portion N-1 of the instrument bracket N.

[0028] Among them, refer to Figure 3-5, the two vertical rods 2 are inserted through the tooling plate 1 and are respectively used for being inserted into two middle connection holes N-2 of the instrument bracket N for positioning. Specifically, two vertical through holes 1-1 are provided on the tooling plate 1; the two vertical rods 2 are respectively inserted through the two vertical through holes 1-1 and can slide up and down. The outer diameters of the two vertical rods 2 respectively match the two middle connection holes N-2 on the instrument bracket N. When the two vertical rods 2 are respectively inserted into the two middle connection holes N-2 to position the instrument bracket N, at this time the position of the instrument bracket N is accurately positioned and horizontally supported (see Figure 6-7 ).

[0029] In addition, see Figure 3-4 , two pressing grooves 2-1 are symmetrically provided on the opposite sides of the two vertical rods 2; when clamping, the left and right ends of the pressing plate 3 are respectively inserted into the two pressing grooves 2-1; the output end of the air cylinder 4 is connected to the lower ends of the two vertical rods 2 through a connecting plate 6. Specifically, the air cylinder 4 is fixed on the lower surface of the tooling plate 1, the output end of the air cylinder 4 is vertically downward and fixedly connected to the connecting plate 6; the lower ends of the two vertical rods 2 are both fixedly connected to the connecting plate 6. In this way, the air cylinder 4 can drive the two vertical rods 2 to move up and down (see Figure 8-9 ).

[0030] Among them, the two positioning and pressing mechanisms 5 are symmetrically arranged on the left and right of the pressing plate 3 and are respectively used for positioning and pressing two nuts M (see Figure 5 ).

[0031] In this embodiment, see Figure 5 , two vertical plates 3-1 are provided at intervals from left to right in the middle of the pressing plate 3; the two positioning and pressing mechanisms 5 are respectively symmetrically arranged on the left and right of the two vertical plates 3-1.

[0032] In this embodiment, see Figure 5 , the positioning and pressing mechanism 5 includes a flat rod A-1 and a spring A-2; a flat through hole 3-11 is provided on the vertical plate 3-1; the flat rod A-1 is inserted through the flat through hole 3-11 and can be slidably matched; one end of the flat rod A-1 is provided with a first step portion A-11 for being inserted into the nut M to position and press it; a retaining ring A-12 is provided on the flat rod A-1; the spring A-2 is sleeved on the flat rod A-1, and the two ends of the spring A-2 are respectively abutted against the vertical plate 3-1 and the retaining ring A-12. Before positioning and pressing the two nuts M, the two positioning and pressing mechanisms 5 need to be in a retracted and contracted state (see Figure 11 ): By pulling the two flat rods A-1 inward, the two flat rods A-1 move toward each other, and the first step portions A-11 of the two flat rods A-1 will approach and the distance between them will be reduced. At this time, when the retaining ring A-12 of the flat rod A-1 approaches the vertical plate 3-1, the spring A-2 will be compressed.

[0033] When the two flat rods A-1 are released, under the action of their respective springs A-2, the two flat rods A-1 automatically move away from each other in the opposite direction. The first step portions A-11 of the two flat rods A-1 will move away from each other and the distance between them will increase until they are completely reset (see Figure 5 ).

[0034] Specifically, the spring A-2 is a compression spring.

[0035] Further, a holding portion A-13 is provided at the other end of the flat rod A-1, which is convenient for holding when operating the flat rod A-1.

[0036] Further, see Figure 3-4 , two L-shaped portions 1-2 are symmetrically provided at the left and right ends of the tooling plate 1; mounting holes 1-21 are provided on the L-shaped portions 1-2. When the tooling is in use, the tooling plate 1 is detachably and fixedly connected to the workbench through the left and right mounting holes 1-21.

[0037] Preferably, see Figure 3-4 , the mounting hole 1-21 is a strip-shaped hole.

[0038] When not clamped, the tooling plate, the two vertical rods, the connecting plate and the cylinder are connected and matched together as a whole (see Figure 3 and Figure 4 ); and the pressing plate and the two positioning and pressing mechanisms thereon are connected and matched together as a whole (see Figure 3 and Figure 5 ).

[0039] The operation steps of this embodiment during clamping are as follows:

[0040] First, place the instrument bracket N on the tooling plate 1, insert the two vertical rods 2 into the two middle connection holes N-2 on the instrument bracket N respectively, and the upper surface of the tooling plate 1 is in contact with the lower surface of the main board portion N-1 of the instrument bracket N (see Figure 6-7 ).

[0041] Then, first, put two nuts M on the first step portions A-11 of the two flat bars A-1 (the two positioning and pressing mechanisms 5) respectively, and pull the two flat bars A-1 towards each other to make them in a close state (i.e., the retracted state); then insert the left and right ends of the pressing plate 3 into the left and right pressing grooves 2-1 respectively and slide and adjust until the two flat bars A-1 are respectively aligned with the two upper connection holes N-4, and then release the two flat bars A-1. Under the action of their respective springs A-2 on the two flat bars A-1, the first step portions A-11 of the two flat bars A-1 respectively position and press the two nuts M (the respective springs A-2 provide the pressing force), and the ends of the first step portions A-11 of the two flat bars A-1 will also be respectively inserted into the two upper connection holes N-4. At this time, the two nuts M are tightly pressed on the opposite side surfaces of the two upper folding portions N-3 and are respectively located at the two upper connection holes N-4 (see Figure 8 ), so as to complete the positioning and pressing of the two nuts M;

[0042] Finally, start the cylinder 4 to work and drive the two vertical bars 2 to move downward. The two vertical bars 2 will move downward simultaneously through the two pressing grooves 2-1 to respectively press the left and right ends of the pressing plate 3, and at the same time, the main board portion N-1 of the instrument support N will also be pressed downward. At this time, the positioning and clamping are completed, that is, the instrument support N and the two nuts M are fixed and constrained and the relative position is accurately positioned (see Figure 9-10 ).

[0043] In addition, after the above positioning and clamping are completed, welding work can be carried out at the contact positions of the instrument support N and the two nuts M; and after the welding is completed, the following unclamping operation can be carried out: First, start the cylinder 4 to work and drive the two vertical bars 2 to move upward. The two vertical bars 2 will move upward simultaneously through the two pressing grooves 2-1 to respectively release the left and right ends of the pressing plate 3, and at the same time, the main board portion N-1 of the instrument support N will also be released; then pull the left and right flat bars A-1 towards each other to move closer (i.e., the retracted state), so that the two flat bars A-1 are pulled closer to each other to make the two first step portions A-11 respectively pull out the two nuts M (see Figure 11 ); then push the pressing plate 3 forward to leave the two pressing grooves 2-1, and then take away the pressing plate 3 and the two positioning and pressing mechanisms 5 on it as a whole; then the welded workpiece (product) can be directly picked out from the tooling plate 1, so that rapid unclamping can be realized.

[0044] Therefore, the tooling of the present utility model can fix and constrain the instrument support N and the two nuts M and keep the relative position accurately positioned, thereby ensuring the welding accuracy and quality.

[0045] In addition, the instrument bracket N and the two nuts M are simple to operate during clamping, and both positioning and pressing are convenient. At the same time, when welding, the welding torch will not interfere during circumferential welding at the contact between the nut M and the upper folded portion N-3, meeting the process requirements, ensuring safe operation, and improving the welding work efficiency.

[0046] In addition, after welding is completed, the welded workpiece can be loosened and unloaded, and the workpiece can be easily taken out. The unloading is very convenient, taking less time and being safe to operate.

[0047] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that:

[0048] Reference can be made to Figure 12 , in this embodiment, two vertical plates 3-1 are provided at the middle part of the pressing plate 3 at intervals left and right; the two positioning and pressing mechanisms 5 are respectively arranged symmetrically left and right on the two vertical plates 3-1.

[0049] Among them, the positioning and pressing mechanism 5 includes a threaded rod B, and a threaded hole 3-12 is provided on the vertical plate 3-1; the threaded rod B is in threaded cooperation with the threaded hole 3-12; one end of the threaded rod B is provided with a second stepped portion B-1 for inserting into the nut M and positioning and pressing it.

[0050] The operation steps of this embodiment during clamping are as follows:

[0051] First, place the instrument bracket N on the tooling plate 1, insert the two vertical rods 2 into the two middle connection holes N-2 on the instrument bracket N respectively, and the upper surface of the tooling plate 1 is in contact with the lower surface of the main board portion N-1 of the instrument bracket N (see Figure 6-7 ).

[0052] Then, first put two nuts M on the second stepped portions B-1 of the two threaded rods B (the two positioning and pressing mechanisms 5) respectively, and rotate the two threaded rods B to a state of approaching each other; then insert the left and right ends of the pressing plate 3 into the left and right two pressing grooves 2-1 respectively and slide and adjust until the two flat rods A-1 are respectively aligned with the two upper connection holes N-4, and then rotate the two threaded rods B clockwise. The two threaded rods B move away from each other, so that the second stepped portions B-1 of the two threaded rods B respectively position and press the two nuts M. The ends of the second stepped portions B-1 of the two threaded rods B will respectively insert into the two upper connection holes N-4. At this time, the two nuts M are tightly pressed on the opposite side surfaces of the two upper folded portions N-3 and are respectively located at the two upper connection holes N-4 (refer to Figure 12 ), to complete the positioning and pressing of the two nuts M.

[0053] Finally, start the cylinder 4 to work again and drive the two vertical rods 2 to move downward. The two vertical rods will move downward through the two pressure grooves 2-1 at the same time to press the left and right ends of the pressing plate 3 respectively, and also press the main board part N-1 of the instrument support N downward. At this time, the positioning and clamping are completed, that is, the instrument support N and the two nuts M are fixed and constrained and the relative position is accurately positioned (refer to Figure 12 ).

[0054] In addition, after the above positioning and clamping are completed, welding work can be carried out at the contact between the instrument support N and the two nuts M; after the welding is completed, the following unclamping operation can be carried out: First, start the cylinder 4 to work and drive the two vertical rods 2 to move upward. The two vertical rods will move upward through the two pressure grooves 2-1 at the same time to release the left and right ends of the pressing plate 3 respectively, and also release the main board part N-1 of the instrument support N; then rotate the two threaded rods B counterclockwise and move closer to each other, so that the second step parts B-1 of the two threaded rods B respectively pull out the two nuts M; then push the pressing plate 3 forward to leave the two pressure grooves 2-1, and then take away the pressing plate 3 and the two positioning and pressing mechanisms 5 thereon as a whole; then the welded workpiece (product) can be directly removed from the tooling plate 1, so rapid unclamping can also be realized.

[0055] It should be noted that the difference between the first embodiment and the second embodiment is only that the specific structures adopted by the positioning and pressing mechanism 5 are different, and correspondingly, two different operation methods for pressing and releasing the two nuts M are used; and the others are exactly the same.

[0056] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
