[0027] Among them, the positioning component 100 may include a positioning block 110, and the line to be welded 500 may be set on the positioning block 110. When the product to be processed 400 is fixed between the fixing member 200 and the positioning component 100, the line to be welded 500 on the positioning block 110 may contact the outer surface of the product to be processed 400, thereby positioning the line to be welded 500 on the product to be processed 400, so as to avoid the problem of inaccurate positioning caused by confirming the relative position of the product to be processed 400 and the line to be welded 500 by manual naked eye observation.

[0028] Further, the positioning block 110 may include a body 111, and a limiting groove 112 may be provided on the body 111. The wire 500 to be welded may be arranged in the limiting groove 112 to position the wire 500 to be welded on the positioning block 110. Specifically, at least two limiting grooves 112 may be provided at intervals on the positioning block 110 to accurately control the spacing between the wires 500 to be welded arranged on the limiting grooves 112, so as to solve the problem of low spacing accuracy between two adjacent wires 500 to be welded.

[0029] The number of the limiting grooves 112 can be set according to actual needs, and this application does not limit it.

The positioning block 110 may be fixed to the second fixing member 120 by the cooperation of the positioning pin 113 and the pin hole 121. In other embodiments, the positioning block 110 may also be fixed to the second fixing member 120 by other means, such as threaded connection, key connection, etc.

[0032] In one embodiment of the present application, a fixing groove 122 may be provided at one end of the second fixing member 120 that fixes the product to be processed 400, and one end of the product to be processed 400 is fixed on the fixing member 200, and the other end may be fixed in the fixing groove 122. The fixed position of the product to be processed 400 may be determined by setting one end of the product to be processed 400 in the fixing groove 122, so that the welding line 500 can directly contact the product to be processed 400, wherein the shape and size of the fixing groove 122 may be set according to the needs of the actual product, and the present application does not limit it here.

[0033] In one embodiment of the present application, the positioning pin 113 and the limiting groove 112 on the positioning block 110 can be arranged at intervals, and the pin hole 121 on the second fixing member 120 can be arranged close to the fixing groove 122, so that when the positioning block 110 is fixed to the second fixing member 120 by the positioning pin 113 and the pin hole 121, the welding line 500 located on the limiting groove 112 can be fully or partially in contact with the product 400 to be processed.

[0034] Further, see Figure 1 , Figure 4 and Figure 5 , Figure 4 is a schematic structural diagram of a fixing member 200 in an embodiment of the present application; Figure 5 2 is a schematic diagram of the structure of the mandrel 220 in one embodiment of the present application. The welding jig 10 may further include a mandrel 220, and a mandrel hole 210 may be provided on the fixing member 200. The mandrel 220 may be fixed to the fixing member 200 through the mandrel hole 210, so that the product 400 to be processed is sleeved on the mandrel 220, so that the product 400 to be processed is positioned on the fixing member 200, so that the other end of the product 400 to be processed can be more accurately set in the fixing groove 122 on the second fixing member 120.

[0035] In one embodiment of the present application, the fixing member 200 may be composed of two upper and lower sub-fixing members to form a spindle hole 210 to facilitate the disassembly and maintenance of the fixing member 200 and the spindle 220 .

Specifically, when the product to be processed 400 is fixed between the fixing member 200 and the second fixing member 120, the welding line 500 will contact the product to be processed 400, and when the welding line 500 reaches the predetermined processing position, the welding line 500 can be welded to the product to be processed 400, and when the welding line 500 does not reach the predetermined welding position, the position of the welding line 500 can be adjusted by rotating the angle rotation assembly 140. In one embodiment of the present application, there may be three limit grooves 112 on the positioning block 110. For example, the predetermined welding position is the position of the middle line 500 to be welded. When it is necessary to process the line 500 to be welded that is not in the predetermined welding position, the angle rotation component 140 can be rotated so that the product 400 to be processed and the positioning block 110 rotate together, so that the line 500 to be welded that has not yet been processed is located at the predetermined processing position for processing.

[0037] Further, see Figure 1 , Figure 6 , Figure 7 and Figure 8 , Figure 6 is a schematic diagram of the mechanism of the angle wheel 141 in one embodiment of the present application, Figure 7 is a schematic diagram of the structure of the angle wheel positioning member 142 in one embodiment of the present application, Figure 8 yes Figure 7 A schematic cross-sectional view of the middle angle wheel positioning member 142 along AA. In one embodiment of the present application, the angle rotation assembly 140 may include an angle wheel 141 and an angle wheel positioning member 142, the first surface 1411 of the angle wheel 141 may be provided with a transition column 130, the end of the transition column 130 away from the angle wheel 141 may be provided with a second fixing groove 131, and the second fixing member 120 may be embedded in the second fixing groove 131 to fix the second fixing member 120 on the transition column 130. In other embodiments, the second fixing member 120 may not be provided separately, but the pin hole 121 and the fixing groove 122 may be directly provided on the transition column 130, the positioning block 110 is directly fixed to the transition column 130 through the pin hole 121 and the positioning pin 113, and then the product 400 to be processed is fixed through the transition column 130.

[0039] In one embodiment of the present application, the angle wheel positioning member 142 may also be provided with a limiting hole 1424, and the second surface 1412 of the angle wheel 141 may also be provided with a tight-fitting column 150. The tight-fitting column 150 may be set in the limiting hole 1424 on the angle wheel positioning member 142. The tight-fitting column 150 is rotated to drive the angle wheel 141 to rotate, thereby driving the transition column 130, the second fixing member 120, the positioning block 110 and the product to be processed 400 to rotate together, so that the line 500 to be welded can be in a predetermined welding position.

[0040] In one embodiment of the present application, the size of the limiting hole 1424 can be set according to the number of the upper limiting grooves 112 on the positioning block 110 and the intervals between the limiting grooves 112. For ease of understanding, see Figure 1 and Figure 2 The number of the limiting grooves 112 on the positioning block 110 can be three. When the positioning block 110 is fixed on the second fixing member 120, the wire to be welded 500 in the middle is in the predetermined processing position, and the corresponding tight-fitting column 150 can be located in the middle of the limiting groove 112. When the wire to be welded 500 on the side of the limiting groove 112 needs to be processed, the tight-fitting column 150 can be rotated left and right so that the wire to be welded 500 is located in the predetermined processing position, wherein the size of the limiting hole 1424 can satisfy that each wire to be welded 500 on the positioning block 110 can be in the predetermined welding position.

[0041] Further, see Figure 1 , Figures 7 to 10 , Fig. 9 1 is a schematic diagram of the structure of a sleeve 180 equipped with a spring 181 in one embodiment of the present application. Fig.10 yes Fig. 9 A schematic cross-sectional view of a sleeve 180 with a spring 181 installed therein along line BB. The positioning assembly 100 may further include a sleeve 180, a spring 181, a round-headed pin 182 and a bolt (not shown), wherein the diameter of the round-headed pin 182 may be greater than the diameter of the opening of the sleeve 180, so as to fix the spring 181 in the sleeve 180. The angle wheel positioning member 142 may further be provided with an assembly hole 1425 and a threaded hole 1426, wherein the assembly hole 1425, the positioning hole 1421 and the limiting hole 1424 are arranged along the axial direction of the angle wheel positioning member 142, and the threaded hole 1426 is arranged along the axial direction perpendicular to the angle wheel positioning member 142, so that the threaded hole 1426 and the assembly hole 1425 may be in an intersecting state.

[0042] In one embodiment of the present application, the assembly hole 1425 can be used to place the sleeve 180 equipped with the spring 181 and the round-headed pin 182, wherein the length of the assembly hole 1425 and the sleeve 180 is not limited, and it is only necessary to meet the requirement that when the sleeve 180 is assembled to the assembly hole 1425, the round-headed pin 182 located in the sleeve 180 partially protrudes from the surface of the angle wheel positioning member 142 on the side close to the angle wheel 141. When the angle wheel 141 is positioned by the angle wheel positioning member 142, the protruding portion of the round-headed pin 182 located in the sleeve 180 can abut against the second surface 1412 of the angle wheel 141, thereby separating the second surface 1412 of the angle wheel 141 from the angle wheel positioning member 142. And when the angle wheel 141 positioned on the angle wheel positioning member 142 rotates, the round-headed pin 182 abutting against the second surface 1412 of the angle wheel 141 can rotate with the angle wheel 141 to assist the rotation of the angle wheel 141.

[0043] In an embodiment of the present application, the bolt may abut against the sleeve 180 through the threaded hole 1426 , thereby fixing the sleeve 180 in the assembly hole 1425 .

[0044] Further, see Figure 6 , Figure 7 and Figure 8 The positioning column 160 on the angle wheel 141 may also include a first column 161 and a second column 162, the diameter of the second column 162 is smaller than the diameter of the first column 161; the positioning hole 1421 on the angle wheel positioning member 142 may be a stepped hole, the stepped hole is provided with a first through hole 1422 and a second through hole 1423, the diameter of the second through hole 1423 is larger than the diameter of the first through hole 1422; the positioning assembly 100 may also include a bearing (not shown) and a washer (not shown), the bearing may be placed in the second through hole 1423, the first column 161 may be arranged in the first through hole 1422, the second column 162 may be arranged in the second through hole 1423 to connect the bearing and the washer arranged in the second through hole 1423, so that the bearing is encapsulated in the second through hole 1423 through the washer, so in the embodiment of the present application, a bearing may be arranged in the second through hole 1423 to assist the rotation of the angle wheel 141.

[0045] Further, see Figure 1The welding jig 10 may also be provided with a first slide rail 171 and a sliding member 190 that slides along the first slide rail 171.

The angle wheel positioning member 142 may be provided with a connecting portion 1427, so that the angle wheel positioning member 142 is fixed to the sliding member 190 through the connecting portion 1427, so that when the sliding member 190 slides on the first slide rail 171, the positioning assembly 100 may be driven to move on the first slide rail 171. Therefore, in the embodiment of the present application, the positioning assembly 100 may slide on the first slide rail 171 to fix or release the product 400 to be processed.

[0046] Furthermore, the base 300 may also include a sliding groove 310 and a second slide rail 172 disposed on both sides of the sliding groove 310, and the positioning assembly 100 may move along the extension direction of the second slide rail 172. Specifically, the angle wheel 141 and the angle wheel positioning member 142 may be partially located in the sliding groove 310 to reduce the distance between the transition column 130 and the base 300. In addition, when the positioning assembly 100 slides in the direction of the fixing member 200, the edge of the sliding groove 310 may abut against the first surface 1411 of the angle wheel 141, or when the positioning assembly 100 moves in a direction away from the fixing member 200, the angle wheel positioning member 142 may also abut against the edge of the sliding groove 310, thereby limiting the sliding range of the positioning assembly 100 on the slide rail 170, and preventing the positioning assembly 100 from being separated from the slide rail 170 due to improper operation.

[0047] Therefore, the welding fixture 10 provided in the present application can sleeve the product 400 to be processed on the mandrel 220 on the fixing member 200, and achieve the purpose of fixing or loosening the product 400 to be processed by sliding the positioning assembly 100 on the slide rail 170. When the product 400 to be processed is fixed between the fixing member 200 and the positioning assembly 100, the wire 500 to be welded can be positioned on the product 400 to be processed, so as to avoid the problem of inaccurate positioning caused by confirming the relative position of the product 400 to be processed and the wire 500 to be welded by manual naked eye observation. And when it is necessary to weld the wire 500 to be welded to the product 400 to be processed, the wire 500 to be welded at the position to be processed can be rotated to the predetermined welding position by rotating the angle wheel 141, so as to facilitate welding the wire 500 to be welded to the product 400 to be processed.
