[0002] With the rapid development of modern manufacturing industry, welding technology has been widely used in mechanical processing, automobile manufacturing, aerospace, electronic components production and other fields. In the field of electronic components manufacturing, the welding process of power electronic components is particularly important, because the performance and life of these components depend on the welding quality to a large extent. However, traditional welding processes are difficult to fully meet the high requirements of power electronic components for precision, reliability and automation.

[0003] After searching, it was found that the prior art publication number is CN112427865A, which discloses a welding tool based on power electronic components. This solution, through the provision of movable clamps and auxiliary reinforcement mechanisms, can, on the one hand, have a good clamping effect on the power electronic components during welding, thereby improving the firmness and stability of the clamping work, and, through the provision of rubber protective pads at the ends of the movable clamps and the movable reinforcement clamps, can avoid damage to the power electronic components when clamping the power electronic components, thereby ensuring the product quality, and, on the other hand, is very convenient for replacing and placing the power electronic components.

[0004] Therefore, based on the above search and in combination with the existing technology, when this solution is used, during the process of clamping and welding components, when the components are welded on the circuit board, the angle that is difficult to weld requires the operator to complete the operation with an uncoordinated movement, then the circuit board needs to be loosened and fixed, the angle needs to be readjusted, and then it needs to be refixed. For the assembly of some components of various types, multiple adjustments are inevitable, especially at complex angles or difficult-to-reach angles. One adjustment may not be ideal and multiple adjustments are required. For this reason, we propose a welding tool based on the manufacture of power electronic components. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-2 A welding tool based on power electronic components includes a base 1, an upper bracket 2 is fixedly welded on the upper end of the base 1, and a plurality of pillars 3 are fixedly welded on the outer surface of the upper bracket 2. The pillars 3 are arranged in a ring shape and are above the base 1. A dial ring 4 is arranged above the base 1. The dial ring 4 is slidably connected with the pillars 3. A movable plate 101 is rotatably installed on the upper end of the pillars 3. A stabilizing cylinder 102 is detachably installed on the upper end of the movable plate 101. The stabilizing cylinder 102 cannot rotate. An extension rod 103 is rotatably installed on one end of the stabilizing cylinder 102 away from the movable plate 101. The extension rod 103 is extended to extend the stabilizing cylinder 102. An adjusting cylinder 301 is rotatably mounted on one end of the extension rod 103 away from the stabilizing cylinder 102. A clamping device for clamping components is provided on the side of the adjusting cylinder 301 away from the extension rod 103. Specifically, the clamping device can clamp the four corners of the electronic components to fix multiple components, thereby reducing the frequency of replacing components during welding. A locking device for locking the rotation angle of the extension rod 103 is provided between the adjusting cylinder 301 and the stabilizing cylinder 102. Specifically, after the extension rod 103 is rotated to any angle, the locking device can lock it at the current position.

[0036] See also Figure 2 , 34. A sleeve 104 is rotatably mounted on the inner upper end of the movable plate 101. A guide wire 11 is wound on the outer surface of the sleeve 104 on the side away from the stabilizing cylinder 102. The sleeve 104 and the movable plate 101 are clamped by a torsion spring. A movable block 6 is slidably mounted on the inner end of the pillar 3. A lock buckle 5 is rotatably mounted on the end of the movable block 6 away from the pillar 3. The lock buckle 5 is located on the outer side of the dial ring 4, and the free end of the guide wire 11 is fixedly connected to the movable block 6. The movable block 6 and the pillar 3 are connected by a reset spring 12. Specifically, the lock buckle 5 rotates with the movable block 6. After the moving block 6 is vertical, the lock buckle 5 is clamped on the outer surface of the dial ring 4. Then, when the dial ring 4 moves up and down, the movable block 6 moves together through the lock buckle 5. A passive rod 105 is passed through the inner end of the stabilizing cylinder 102. A limit plate is fixedly installed on the outer surface of the passive rod 105. A slide groove is opened at the inner end of the stabilizing cylinder 102. The limit plate is located in the slide groove. When the passive rod 105 slides left and right in the stabilizing cylinder 102, it can avoid self-rotation. A screw is fixedly installed on one end of the passive rod 105 close to the movable plate 101, and the sleeve 104 is threadedly connected with the screw.

[0037] A stabilizing toothed ring 106 is fixedly installed at one end of the extension rod 103 close to the stabilizing cylinder 102, and the teeth of the stabilizing toothed ring 106 face inwards. A spring piece 107 is fixedly installed at one end of the stabilizing cylinder 102 close to the extension rod 103, and the spring piece 107 is located in the stabilizing toothed ring 106. Specifically, the convex point of the spring piece 107 is located at the trough of the stabilizing toothed ring 106. When the extension rod 103 rotates, the convex point of the spring piece 107 moves from between the peaks and troughs in the stabilizing toothed ring 106. Then, the spring piece 107 tightly abuts against the trough of the stabilizing toothed ring 106 under the action of elastic force, so that the extension rod 103 can maintain the current rotation angle.

[0038] More specifically, a rectangular block is fixedly mounted on one end of the passive rod 105 away from the sleeve 104, and a rectangular groove is formed at the inner end of the extension rod 103, and the rectangular groove corresponds to the rectangular block. Therefore, whenever the rectangular block is inserted into the rectangular groove, the extension rod 103 maintains the current position and will not be changed in angle by external force.

[0039] See also Figure 3 , 5, 6, 7, the locking device includes a passive cylinder 302, which is rotatably mounted on the inner end of the adjusting cylinder 301. Specifically, the passive cylinder 302 is located in the adjusting cylinder 301 on a side close to the extension rod 103, and a plurality of rectangular holes are provided on the outer surface of the passive cylinder 302, which are arranged in a ring shape, and top columns 306 are penetrated in the rectangular holes, and the top columns 306 are connected by corrugated sheets, and the corrugated sheets have a certain elasticity, so that a plurality of corrugated sheets are combined together to form a ring shape, and an adjusting toothed ring 307 is fixedly mounted on the inner end of the extension rod 103, and the top column 306 is located inside the adjusting toothed ring 307, and the top column 306 is clamped between two adjacent teeth in the adjusting toothed ring 307, and a limiter 310 is fixedly mounted on the inner end of the extension rod 103, and the limiter 310 corresponds to the adjusting toothed ring 307;

[0040] like Figure 5 , 7 The end of the limiter 310 close to the adjusting toothed ring 307 is slidably mounted with a clamping column 308. Specifically, the ends of the clamping column 308 and the limiter 310 close to each other are fixedly mounted with a plurality of arc plates, and the arc plates are interlaced and engaged with each other to avoid the phenomenon of self-rotation of the clamping column 308 during movement. Specifically, the outer surface of the limiter 310 is rotatably mounted with a wire wheel 309, and the wire wheel 309 is sleeved on the outer surface of the clamping column 308. The outer surface of the arc plate on the clamping column 308 is provided with a spiral groove. 09 The threaded sleeve is arranged on the outer surface of the spiral groove, the wire wheel 309 and the limiter 310 are connected by a torsion spring, the outer surface of the wire wheel 309 is wound with a driving rope 108, and the free end of the driving rope 108 is fixedly connected to the passive rod 105. More specifically, the central part of the extension rod 103 is hollowed out, and after the driving rope 108 passes through the interior of the extension rod 103 and reaches the stabilizing cylinder 102, it is connected to the center of the passive rod 105 after turning, so that the passive rod 105 can pull the driving rope 108 when moving;

[0041] The diameter of the clamping column 308 is equal to the inner diameter of the ring-shaped corrugated sheet. When the clamping column 308 is inserted into the passive cylinder 302, the top column 306 is blocked by the clamping column 308 when moving toward each other, so it cannot continue to move, and the passive cylinder 302 cannot rotate.

[0042] Example 2: Please refer to Figure 6 , 8, a welding tool based on power electronic components, based on Example 1, a passive block 312 is rotatably installed at the inner end of the adjusting cylinder 301, the passive block 312 and the adjusting cylinder 301 are clamped by a reset torsion spring, the passive block 312 and the passive cylinder 302 are fixedly connected by a center rod 305, a locking rod 314 is slidably installed at the inner end of the adjusting cylinder 301, and the locking rod 314 and the adjusting cylinder 301 are connected by a resistance spring 313, a plurality of grooves are provided on the outer surface of the passive block 312, the contact end of the locking rod 314 is inserted into any groove, and a locking sleeve is provided on the outer surface of the passive block 312 The locking sleeve 311 has an end away from the center rod 305 and an adjusting wheel 304 is fixedly mounted thereon. The adjusting wheel 304 is located outside the adjusting cylinder 301. Specifically, the contact end of the locking rod 314 is in an arc shape. When the passive block 312 rotates, the arc of the contact end of the locking rod 314 and the groove are squeezed by each other, so that the locking rod 314 is squeezed out of the groove. When the notch outside the locking sleeve 311 is stuck outside the locking rod 314, the groove on the outer surface of the passive block 312 will be increased by a locking sleeve 311. Then, the contact end of the current locking rod 314 will be blocked by the locking sleeve 311, so that the passive block 312 cannot rotate.

[0043] More specifically, a protrusion is fixedly installed at one end of the adjusting wheel 304 close to the adjusting cylinder 301, and a groove is opened at one end of the adjusting cylinder 301 close to the adjusting wheel 304, and the groove corresponds to the protrusion. After the adjusting wheel 304 moves toward the passive block 312, the protrusion penetrates the groove, so that the adjusting wheel 304 cannot continue to rotate;

[0044] See also Figure 6 , 9 The clamping device includes a stabilizing tube 204, which is located on the right side of the adjusting tube 301. A ball shell 205 is fixedly installed at one end of the stabilizing tube 204 close to the adjusting tube 301. A movable ball 303 is fixedly installed at the right end of the adjusting tube 301. The ball shell 205 is sleeved on the outer surface of the movable ball 303. Specifically, a plurality of rectangular holes are opened on the outer surface of the ball shell 205, and the rectangular holes are staggered in a "cross" shape. A plurality of cylinders are fixedly installed on the outer surface of the movable ball 303, and the cylinders are inserted into the rectangular holes. The space in the rectangular holes is larger than the volume of the cylinders. Therefore, under the limitation of the rectangular holes on the outer surface of the ball shell 205, the deflection angle of the stabilizing tube 204 is limited to a certain extent to prevent the stabilizing tube 204 from rotating.

[0045] A stabilizing block 201 is fixedly installed on the right end of the stabilizing tube 204. Two clamping blocks 202 are rotatably installed on one end of the stabilizing block 201 away from the stabilizing tube 204. The clamping blocks 202 are symmetrically arranged up and down. Rubber pads are fixedly installed on the ends of the two clamping blocks 202 close to each other to prevent damage to the outer surface of the electronic components. A movable shell 209 is slidably installed on the inner end of the stabilizing tube 204. A sliding hole is opened on the outer surface of the stabilizing tube 204. A rack 207 is fixedly installed on the outer surface of the movable shell 209, and the rack 207 is inserted into the sliding hole. A locking ring 203 is rotatably installed on the outer surface of the stabilizing tube 204, and the locking ring 203 is threadedly sleeved on the outer surface of the rack 207.

[0046] Specifically, a hole is opened at the inner end of the movable ball 303, and a limiting rope 206 is wound on the outer surface of the center rod 305. The free end of the limiting rope 206 passes through the hole in the movable ball 303 and is fixedly connected to the inner end of the movable shell 209. The inner end of the clamping block 202 is fixedly installed with a traction rope 208, and the free end of the traction rope 208 is fixedly connected to the movable shell 209.

[0047] The working principle of the present invention is:

[0048] Before use, the corners of the components to be processed are placed between the two clamping blocks 202, and then the locking ring 203 is rotated, and the rack 207 starts to move under the action of the threaded connection with the locking ring 203, and drives the movable shell 209 to move. At this time, the movable shell 209 pulls the clamping blocks 202 toward each other through the traction rope 208 to achieve the clamping of the components;

[0049] When in use, the positions of the components are adjusted to make the welding process more convenient. When adjusting the positions of the components, each lock buckle 5 is buckled on the outer surface of the dial ring 4, and then the dial ring 4 is pressed down, so that each lock buckle 5 is lowered at the same time, and the movable block 6 is driven to lower, the return spring 12 is compressed, and the sleeve 104 is driven to rotate through the traction of the guide wire 11, and the passive rod 105 moves to the left side, and then the passive rod 105 pulls the driving rope 108, and the driving rope 108 is pulled to drive the wire wheel 309 to rotate, and the angle of the stabilizing block 201 is adjusted. Then, when the notch outside the locking sleeve 311 is stuck outside the locking rod 314, the groove on the outer surface of the passive block 312 will be added with a layer of locking sleeve 311, then the contact end of the current locking rod 314 will be blocked by the locking sleeve 311, so that the passive block 312 cannot rotate, and the limit rope 206 is restricted at this time, and the ball shell 205 cannot rotate at this time;

[0050] At this time, the clamping column 308 moves in a direction away from the top column 306 under the rotation of the wire wheel 309. At this time, the stabilizing tube 204 and the extension rod 103 can be rotated at any angle. Then, under the mutual engagement between the top column 306 and the adjusting toothed ring 307, the stabilizing tube 204 can be rotated only when an external force is applied.

[0051] Then, the shifting ring 4 is released, and the movable block 6 is pushed upward by the elastic force of the return spring 12, and the sleeve 104 and the wire wheel 309 rebound to lock the current angle position of the extension rod 103 and the stabilizing tube 204;

[0052] To adjust the position of individual components, you only need to open the lock 5 of the corresponding component, press the lock 5 to unlock its angle, and then adjust the position angle of a certain component, while the positions of other components remain unchanged. Or when clamping a circuit board, by changing the angle of a certain angle, the circuit board can be displayed at multiple angles, so that the operator can avoid the tricky angles of the circuit board during welding and avoid welding with uncoordinated postures.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
