[0033] The present invention provides Figure 1 A resistance welding spot welding machine shown includes a spot welding machine body 1, and also includes:

[0034] There are two placing mechanisms 2, which are symmetrically arranged at both ends of the inner side of the spot welding machine body 1, and are used to place the mobile power supply assembly to be welded;

[0035] There are two welding mechanisms 3, which are respectively arranged at two ends of the inner wall of one side of the spot welding machine body 1, and are used to perform spot welding operations on mobile power supply assemblies.

[0036] In order to conveniently place and fix multiple mobile power supply assemblies, such as Figure 1-3 and Figure 5As shown, the placement mechanism 2 includes a placement plate 201, and four placement grooves 202 are opened in a circular manner with equal intervals on the top inner wall of the placement plate 201. Clamping plates 205 are arranged on both sides of the inner walls of the four placement grooves 202, and fastening bolts 206 are arranged between the clamping plates 205 and the inner wall of the placement plate 201. A connecting rod 207 is fixedly installed at the bottom of the placement plate 201, and an adjusting plate 208 is fixedly installed at the bottom of the connecting rod 207. The four placement grooves 202 can place four mobile power supply assemblies, the clamping plates 205 can clamp and fix the mobile power supply assemblies inside the placement grooves 202, and the fastening bolts 206 can fix the adjusted clamping plates 205, so that the placement mechanism 2 can place and fix multiple mobile power supply assemblies, so that the device can conveniently perform spot welding operations on multiple mobile power supply assemblies.

[0037] In order to facilitate the installation and fixation of the welding mechanism 3, as Figure 1-2 and Figure 4 , Figure 6 As shown, the spot welding machine body 1 includes a fixed frame 101, a placement box 102 is opened on the inner wall at the bottom of the fixed frame 101, and installation grooves 103 are opened at both ends of the inner wall of one side of the vertical part of the fixed frame 101. The welding mechanism 3 includes an adjusting screw rod 301, and the adjusting screw rod 301 is rotatably installed on the inner wall of the adjacent installation groove 103. The top of the adjusting screw rod 301 passes through the top of the fixed frame 101 and is provided with a second motor 302. The installation groove 103 can install and fix the adjusting screw rod 301, so that the welding mechanism 3 can be installed on the inner wall of one side of the fixed frame 101. The second motor 302 drives the adjusting screw rod 301 to rotate to adjust the height of the welding head 310.

[0038] In order to conveniently adjust the position of the mounting plate 305, Figure 2 and Figure 6As shown, the outer side of the adjusting screw rod 301 is threadedly sleeved with a movable frame 303, the outer wall of one side of the movable frame 303 is movably connected to the inner wall of the adjacent mounting groove 103, a fixed rack 304 is fixedly installed on the inner wall of the top of the movable frame 303, and the outer wall of the movable frame 303 away from the adjusting screw rod 301 is movably sleeved with a mounting plate 305, and a movable gear 306 meshing with the fixed rack 304 is rotatably installed on the inner top of the mounting plate 305. The height of the movable frame 303 can be adjusted by rotating the adjusting screw rod 301, and the mounting groove 103 can be adjusted. The movement of the movable frame 303 is limited so that it remains stable during the height adjustment process. The electric rotating rod fixedly sleeved on the inner wall of the movable gear 306 works, and through the meshing action between the movable gear 306 and the fixed rack 304, the mounting plate 305 can be moved horizontally along the outer wall of the movable frame 303. The left-view vertical section of the part of the movable frame 303 located outside the mounting groove 103 is set as an H-shaped structure, which can limit the movement of the mounting plate 305, so that the mounting plate 305 remains stable during the horizontal movement.

[0039] In order to facilitate further adjustment of the position of the welding joint 310, as Figure 2 and Figure 6 As shown, electric push rods 307 are fixedly installed on the top and bottom of one end of the mounting plate 305 away from the movable frame 303, and a movable plate 308 is fixedly installed on the piston rods of the two electric push rods 307. A hydraulic cylinder 309 is fixedly installed on the top of one side of the movable plate 308 away from the mounting plate 305, and a welding head 310 is fixedly installed on the bottom of the piston rod of the hydraulic cylinder 309. The two electric push rods 307 extend to allow the movable plate 308 to move along the longitudinal horizontal position. At the same time, the height of the welding head 310 can be further adjusted through the operation of the hydraulic cylinder 309, so that the welding head 310 can perform spot welding operations on the mobile power supply assembly inside the placement slot 202, and the position of the welding head 310 can be adjusted to facilitate spot welding operations on different positions of the mobile power supply assembly.

[0040] In order to conveniently replace the position of the mobile power assembly to be spot welded, such as Figure 2 , Figure 4-5As shown, the placement mechanism 2 also includes a first motor 209, which is fixedly installed at one end of the top inner wall of the placement box 102, and a rotating plate 210 is fixedly sleeved on the outer side of the output shaft of the first motor 209, and the rotating plate 210 pushes the adjusting plate 208 to rotate intermittently. The placement box 102 can install and fix the first motor 209. The operation of the first motor 209 causes the rotating plate 210 to rotate, and then the rotating plate 210 can push the adjusting plate 208 to rotate, and then the placement plate 201 can be driven to rotate intermittently, and then the positions of the four placement slots 202 can be replaced, so that the welding mechanism 3 can perform spot welding operations on the four mobile power supply assemblies in turn, and then through the arrangement of two placement mechanisms 2 and two welding mechanisms 3, the device can conveniently perform spot welding operations on multiple mobile power supply assemblies, thereby improving the efficiency of mobile power supply assembly.

[0041] In order to conveniently place and fix the mobile power assembly, such as Figure 2-3 and Figure 5 As shown, traction springs 204 are fixedly installed on both sides of the inner wall of the placement groove 202, and the end away from the inner wall of the placement groove 202 is fixedly connected to the adjacent clamping plate 205. Four fixing grooves 203 are opened in a ring around the middle of the top of the placement plate 201 at equal intervals. The inner wall of the end of the clamping plate 205 away from the placement groove 202 is threadedly connected to the outer wall of the adjacent fastening bolt 206, and the bottom of the fastening bolt 206 is in contact with the bottom of the inner wall of the adjacent fixing groove 203. The clamping plate 205 can clamp and fix the mobile power assembly under the elastic force of the traction spring 204, and the fastening bolt 206 penetrates the clamping plate 205 and is in contact with the inner wall of the fixing groove 203 to fix the clamping plate 205, so that the mobile power assembly remains stable inside the placement groove 202, and the mobile power assembly remains stable during the spot welding process.

[0042] When spot welding the mobile power assembly, the assembly is placed inside the placement slot 202, which will squeeze the clamping plate 205 to make it move to both sides, thereby causing the two traction springs 204 to contract. When the assembly is placed, the clamping plate 205 can clamp the assembly under the elastic force of the traction spring 204, and then the clamping bolt 206 is used to penetrate the inner wall of the clamping plate 205 and contact the inner wall of the fixing slot 203 to fix the clamping plate 205, so that the mobile power assembly can remain stable inside the placement slot 202, and then the second motor 302 works to adjust the screw rod 30 1 rotates, thereby driving the movable frame 303 to move along the inner wall of the installation slot 103 on its outer side, and then the movable gear 306 rotates through the operation of the electric rotating rod, and the mounting plate 305 moves along the outer wall of the movable frame 303 through the meshing action between the movable gear 306 and the fixed rack 304, and then the two electric push rods 307 work to drive the movable plate 308 to move along the longitudinal horizontal direction, and at the same time, the hydraulic cylinder 309 works to further adjust the height of the welding head 310, so that the welding head 310 can perform spot welding operation on the mobile power assembly inside one of the placement slots 202;

[0043] When the spot welding of the mobile power assembly inside one of the placement slots 202 is completed, the first motor 209 is operated to make the rotating plate 210 rotate, which can then push the adjusting plate 208 to rotate. Through the transmission action of the connecting rod 207, the placement plate 201 rotates accordingly, and then the positions of the four placement slots 202 can be replaced, so that the welding head 310 can perform spot welding operations on the mobile power assembly inside the four placement slots 202 in turn. Similarly, the two placement mechanisms 2 and the welding mechanism 3 can perform spot welding operations on multiple mobile power assembly parts, thereby improving the spot welding efficiency of the mobile power assembly parts, and thereby improving the efficiency of mobile power assembly. This embodiment specifically solves the problem in the prior art that the spot welding machine cannot conveniently place and fix multiple mobile power assembly parts, and cannot replace the welding position, which will affect the spot welding efficiency of the mobile power assembly parts.

[0044] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
