Description

Technical Field

[0001] The invention relates to the technical field of welding processing, and in particular to a dry-type transformer component welding device. Background Art

[0002] The terminal block is one of the common components in dry-type transformers. It is used to connect cables, wires or other electrical equipment to ensure the effective connection between the internal circuit and the external circuit of the dry-type transformer. The terminal block consists of a fixing seat for fixing to the base and a terminal tube for clamping and fixing the cable with bolts; the terminal tube is an L-shaped structure, the horizontal section of the terminal tube is a C-shaped structure, which is used to clamp and fix the cable, and the vertical section of the terminal tube is a rectangular structure and is welded to the fixing seat (such as Fig.10 as shown).

[0003] The existing welding method is to squeeze and fix the C-shaped section of the terminal tube through a fixing piece to avoid blocking the lower surface of the rectangular section of the terminal tube, then dock the lower end of the fixed terminal tube with the fixed fixing seat, and then weld the joint.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 As shown, a dry-type transformer assembly welding device includes a base 10; two support plates 11 are symmetrically installed on the base 10, and a load-bearing plate 12 is provided on the opposite sides of the two support plates 11, and shaft columns 13 are installed on the opposite ends of the two load-bearing plates 12, and the shaft columns 13 rotate and penetrate the corresponding support plates 11, a limiting mechanism 2 is provided between the two load-bearing plates 12, and a welding mechanism 3 located above the limiting mechanism 2 is provided on the base 10.

[0035] like Figure 1 and Figure 3As shown, the limiting mechanism 2 includes a fixed plate 20, which is installed between the two load-bearing plates 12, and the fixed plate 20 is an inverted structure. A cover plate 21 is installed on the lower end surface of the fixed plate 20, and a pressure plate 23 is installed on the upper end surface of the fixed plate 20 through a support 22. The lower end of the support 22 slides through the horizontal section of the fixed plate 20 and is jointly installed with a connecting plate 24. A No. 1 cylinder 25 is installed on the lower end surface of the cover plate 21, and the telescopic end of the No. 1 cylinder 25 slides through the cover plate 21 and is fixedly connected to the connecting plate 24.

[0036] like Figure 1 , Figure 3 and Fig.10 As shown, the rear side of the fixing plate 20 is provided with a fixing portion 27 for fixing the terminal tube and docking with the fixing seat, the fixing plate 20 is provided with an extrusion portion 26 for fixing the fixing seat, and the fixing plate 20 is also provided with a pushing portion 28 for pushing the welded terminal out of the material.

[0037] During the specific work, the fixing seat is manually placed at the position of the extrusion part 26, and then the terminal tube is placed at the position of the fixing part 27. Then the No. 1 cylinder 25 pushes the connecting plate 24 to move downward. The connecting plate 24 drives the pressure plate 23 to move downward through the support 22 so that the pressure plate 23 squeezes and limits the fixing seat from top to bottom. At the same time, the left and right sides of the fixing seat are squeezed and limited by the extrusion part 26. Then the fixing part 27 clamps and fixes the terminal tube, and fits the terminal tube to the fixing seat. Then the welding mechanism 3 welds the connection between the terminal tube and the fixing seat. After the welding is completed, the pressure plate 23, the extrusion part 26 and the fixing part 27 release the limit on the fixing seat and the terminal tube. Then the pushing part 28 pushes the welded terminal out for blanking. Then the fixing seat and the terminal tube to be welded are placed. Repeat the above operation for welding.

[0038] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the extrusion portion 26 includes an extrusion assembly, and a plurality of groups of extrusion assemblies located below the pressure plate 23 are installed on the upper end surface of the fixed plate 20 from left to right, and the extrusion assembly is composed of two left-right symmetrical pushing plates 260. A slide groove is provided at a position corresponding to the pushing plates 260 on the fixed plate 20, and a block 261 fixedly connected to the corresponding pushing plate 260 is slidably installed in the slide groove, and a return spring 262 is installed between the block 261 and the inner wall of the slide groove. An extrusion block 263 is installed at a position corresponding to the pushing plate 260 on the lower end surface of the pressure plate 23, and the position where the extrusion block 263 contacts the pushing plate 260 is an inclined surface, and a prefabricated fixture 4 for pre-fixing the fixed seat is arranged between each group of pushing plates 260.

[0039] like Figure 6 and Figure 7As shown, the prefabricated component 4 includes a circular groove, and the portion of the fixed plate 20 located between the two pushing plates 260 of the same group is symmetrically provided with a circular groove, in which a limiting column 41 is installed through a No. 1 compression spring 40, and the upper part of the limiting column 41 is a truncated cone structure with a small upper part and a large lower part.

[0040] During specific work, the fixing plate 20 is manually pushed from front to back between the two pushing plates 260 of the same group, and the fixing seat will conflict with the limiting column 41. As the fixing seat is pushed forward, the limiting column 41 is squeezed and moved downward, so that the fixing seat can continue to move backward until the screw hole on the rear side of the fixing seat moves to the position of the limiting column 41. The limiting column 41 moves upward under the action of the No. 1 compression spring 40 to conflict with the screw hole of the fixing seat to pre-position the fixing seat, and then the No. 1 cylinder 25 drives the pressure plate 23 to move downward through the connecting plate 24 and the support 22, and the pressure plate 23 drives the extrusion block 263 to conflict with the pushing plate 260, so that the two pushing plates 260 of the same group move toward the corresponding fixing seat to squeeze and fix the fixing seat to limit its left and right movement. At the same time, the pressure plate 23 pushes the fixed seat to fit with the fixed plate 20 to limit the up and down movement of the fixed seat.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixing portion 27 includes a supporting plate 270, and the front side of the fixing plate 20 is installed with the supporting plate 270 for sliding up and down through a No. 1 electric slider, and a sliding component is arranged at a position where the front end surface of the supporting plate 270 corresponds to the extrusion component, and the sliding component is composed of two left-right symmetrical slide plates 271, and a linkage member 5 is arranged between the two slide plates 271 in the same group, and the upper end surfaces of the slide plates 271 are installed with L-shaped plates 272, and the opposite surfaces of the horizontal sections of the two L-shaped plates 272 in the same group are installed with clamping blocks 273 through connecting blocks, and the opposite surfaces of the two clamping blocks 273 in the same group are provided with arc grooves that cooperate with the horizontal sections of the terminal tubes, and the opposite ends of the two clamping blocks 273 in the same group are installed with rectangular plates, and the opposite surfaces of the two rectangular plates in the same group are installed with positioning plates 275 through No. 2 compression springs 274, and the opposite ends of the two clamping blocks 273 in the same group are provided with inner support members 6.

[0042] like Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the inner support member 6 includes a guide column 60, and the rear end face of the clamping block 273 is installed with a guide column 60, and a limit plate 61 is arranged on the guide column 60, and a disc 62 is fixedly installed between the two limit plates 61 in the same group, and guide grooves 63 are evenly opened on the disc 62 along its circumference, and a limit rod 64 is slidably installed in the guide groove 63, and a No. 1 connecting plate 65 is installed between two adjacent limit plates 61, and a vertical plate 66 is symmetrically installed on the upper end face of the supporting plate 270, and the vertical plate 66 is fixedly connected to the corresponding limit plate 61 through a No. 2 connecting plate 67, and a driving member 8 for driving the limit rod 64 to contact the inner wall of the horizontal section of the terminal tube is arranged on the disc 62.

[0043] like Figure 1 and Figure 2 As shown, the linkage member 5 includes a No. 2 spur gear 50, and a No. 2 spur gear 50 is rotatably installed on the supporting plate 270 between the two slides 271 of the same group through a torsion spring rod. A No. 2 rack 51 is meshed on the upper and lower sides of the No. 2 spur gear 50, and the two No. 2 racks 51 of the same group are respectively fixedly connected with the corresponding two slides 271, and the lower ends of the slides 271 on the left side of each group of sliding components are commonly fixedly installed with a driving plate 52, and the front end surface of the vertical plate 66 on the left side is installed with a No. 2 cylinder 53, and the telescopic section of the No. 2 cylinder 53 is installed with a pressure block 54, and the pressure block 54 is slidably connected to the supporting plate 270, and the surfaces that contact between the pressure block 54 and the driving plate 52 are both inclined surfaces.

[0044] like Figure 3 , Figure 4 and Figure 7 As shown, the driving member 8 includes a turntable 80, and the turntable 80 is rotatably installed at the rear end of the disc 62 through a rotating shaft. Arc-shaped waist grooves 81 are provided at positions on the turntable 80 corresponding to the limiting rods 64, and the limiting rods 64 slide through the corresponding arc-shaped waist grooves 81, and a No. 2 waist groove is provided on the limiting plate 61. After the guide column 60 slides through the corresponding No. 2 waist groove, a connecting rod 82 is rotatably installed, and the other end of the connecting rod 82 is eccentrically hinged to the corresponding turntable 80.

[0045] During specific operation, the terminal tube is manually sleeved on the corresponding limit rod 64 and fits with the corresponding disc 62, and then the No. 2 cylinder 53 pushes the pressure block 54 to move downward, and the pressure block 54 will push the driving plate 52 to move to the right, and the driving plate 52 drives the slide plate 271 on the left side of the same group to move to the right, and the moving slide plate 271 drives the corresponding other slide plate 271 to move toward the corresponding terminal tube through the cooperation of the No. 2 spur gear 50 and the No. 1 rack 92, so that the two slide plates 271 of the same group drive the corresponding two clamping blocks 273 to move toward the corresponding terminal tube through the L-shaped plate 272, and as the clamping block 273 moves, the positioning plate 275 will conflict with the vertical section of the corresponding terminal tube, and the terminal tube will be pre-aligned by the two positioning plates 275 of the same group, and then as The continued movement of the clamping block 273 will squeeze and fix the terminal tube, and during the movement, the clamping block 273 will push the corresponding connecting rod 82 through the guide column 60, and the connecting rod 82 will push the corresponding turntable 80 to rotate. During the rotation of the turntable 80, the inner wall of the arc waist groove 81 pushes the limit rod 64 to move toward the inner wall of the corresponding terminal tube, so that the limit rod 64 contacts the inner wall of the terminal tube, thereby improving the stability of the terminal tube. At the same time, the terminal tube is squeezed and fixed inside and outside by the clamping block 273 and the limit rod 64, which can ensure that the terminal tube is evenly stressed and prevent the terminal tube from being deformed due to squeezing; after the terminal tube is fixed, the No. 1 electric slider (not shown in the figure) drives the supporting plate 270 to move downward, and the supporting plate 270 drives the fixed terminal tube to fit with the corresponding fixing seat for subsequent welding processing.

The welding assembly 32 adopts the existing technology and can realize steering and lifting actions through the existing driving source (such as a motor and an electric push rod) to perform welding operations.

[0047] During specific operation, the No. 3 electric slider (not shown in the figure) drives the welding assembly 32 to move from right to left through the support rod 31. When the welding assembly 32 moves through the connection between the terminal tube and the fixed seat, it will be welded. After a row of terminals is welded, the No. 3 electric slider (not shown in the figure) drives the welding assembly 32 to move to the left side of the vertical plate 66 on the left side through the support plate 11 to avoid interfering with the rotation of the limiting mechanism 2. After the welding assembly 32 moves and resets, the external motor installed on the support plate 11 drives the shaft column 13 to rotate. The shaft column 13 drives the limiting mechanism 2 and the fixed fixing seat and the terminal tube to rotate ninety degrees clockwise through the load-bearing plate 12. Then the No. 3 electric slider (not shown in the figure) drives the welding assembly 32 to move to the right to weld the connection on the other side after the fixing seat and the terminal tube are connected. After welding is completed, the welding assembly 32 further moves to the right away from the corresponding vertical plate 66 to reset, and the external motor drives the limiting mechanism 2 to rotate ninety degrees counterclockwise through the shaft column 13 and the load-bearing plate 12 to reset.
