[0025] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0026] The utility model provides a brake resistor welding device, aiming to solve the problems of complex structure and low welding efficiency of the existing brake resistor welding device.

[0027] like Figure 1 and Figure 2As shown, the utility model provides a brake resistor welding device, which is used for welding two brake resistors 5, and the brake resistor 5 is provided with a waist-shaped hole. The brake resistor welding device comprises a base 1, a workbench 2, a moving mechanism 3 and a welding mechanism 4, and the moving mechanism 3 is arranged on the base 1; the workbench 2 comprises a bearing platform 21 and a fixed seat 22, the bearing platform 21 is arranged on the moving mechanism 3, the bearing platform 21 is used to support the brake resistor 5, and the fixed seat 22 is arranged on the bearing platform 21, and the fixed seat 22 is arranged opposite to the welding space 43, and the fixed seat 22 includes The boss 223 is matched with the waist-shaped hole, and the boss 223 is used to be engaged with the waist-shaped hole to fix the brake resistor 5; the welding mechanism 4 includes a first welding component 41 and a second welding component 42 which are relatively arranged on the base 1, and a welding space 43 is formed between the first welding component 41 and the second welding component 42; the moving mechanism 3 can drive the fixing seat 22 to move between the first position and the second position to make the boss 223 enter or exit the welding space 43, and the first welding component 41 and the second welding component 42 cooperate to weld two brake resistors 5.

[0028] In actual operation, the two brake resistors 5 are respectively connected to the boss 223 through the waist-shaped holes, and the two brake resistors 5 are pressed against each other. The shape of the boss 223 matches the shape of the waist-shaped hole, so that the brake resistor 5 and the boss 223 are closely matched to prevent the brake resistor 5 from shifting during the movement or welding process. At this time, the fixed seat 22 is in the first position, and the moving mechanism 3 drives the fixed seat 22 to move from the first position to the second position, so that the two brake resistors 5 enter the welding space 43. The first welding assembly 41 and the second welding assembly 42 cooperate to weld the two brake resistors 5, and the moving mechanism 3 continues to move with the fixed seat 22 during the welding process to move between the two brake resistors. Multi-point welding is performed on the plate 5; after welding is completed, the moving mechanism 3 drives the fixing seat 22 to move from the second position to the first position, and the two brake resistor plates 5 withdraw from the welding space 43, so that the operator can flip the two brake resistor plates 5 to weld the other end, or replace the new brake resistor plate 5 to be welded for the next welding operation, so as to avoid interference with surrounding components when replacing the brake resistor plate 5. The utility model has a simple structure and is easy to operate. The operator only needs to set the brake resistor plate 5 on the boss 223 through the waist-shaped hole and engage the boss 223 to fix the brake resistor plate 5. The operation process is simple, which is conducive to reducing the time of welding operations and improving welding efficiency.

[0029] See also Figure 3The fixing seat 22 includes an extension section 221, a mounting section 222 and a boss 223 connected vertically. The extension section 221 is extended from the bearing platform 21 along the first direction toward the direction close to the welding mechanism 4. The mounting section 222 is provided with a vertical mounting surface 2221 parallel to the first direction. The boss 223 is arranged on the vertical mounting surface 2221, and the boss 223 is protruded from the vertical mounting surface 2221 perpendicular to the first direction toward the direction away from the mounting section 222. The extension section 221 can make a certain distance between the boss 223 and the bearing platform 21, so as to ensure that when the boss 223 enters or exits the welding space 43, the bearing platform 21 will not interfere with the welding mechanism 4. The boss 223 is arranged on the vertical mounting surface 2221 parallel to the first direction, so that the brake resistor 5 is in a vertical state when it is engaged with the boss 223, so as to facilitate the welding operation of the first welding assembly 41 and the second welding assembly 42.

The first moving component 31 is used to drive the second moving component 32 to rise or fall, and the second moving component 32 can drive the carrying platform 21 to move along the first direction. When the boss 223 enters the welding space 43, the first moving component 31 drives the second moving component 32 to drive the carrying platform 21 to rise until the boss 223 is higher than the welding mechanism 4, and then the second moving component 32 drives the carrying platform 21 to move along the first direction to move the fixed seat 22 to above the welding space 43, and then the first moving component 31 drives the second moving component 32 to electrically drive the carrying platform 21 down until the fixed seat 22 moves to the second position. At this time, the boss 223 enters the welding space 43, and the first welding component 41 and the second welding component 42 cooperate to weld the two brake resistors 5. After the welding is completed, the above steps are reversed to move the fixed seat 22 from the second position to the first position, thereby avoiding the fixed seat 22 and the brake resistor 5 clamped on the boss 223 from interfering with the welding mechanism 4 and causing deformation when the moving mechanism 3 is running, thereby ensuring the normal operation of the welding device.

[0032] Preferably, the guide rod 312 includes a sleeve and a sliding rod. The sleeve is arranged on the base 1, and the sleeve is arranged opposite to the sliding groove 11. The sliding rod is slidably arranged in the sleeve, and one end of the sliding rod exposed from the sleeve passes through the sliding groove 11 and is connected to the supporting platform 21. The supporting platform 21 rises or falls to drive the sliding rod to slide along the sleeve.

[0033] In one embodiment, the second moving component 32 includes a second driving member 321, a screw transmission structure 322 and a slide plate 323. The second driving member 321 is arranged on the base 1, and the second driving member 321 is connected to the slide plate 323 through the screw transmission structure 322. The slide plate 323 is slidably arranged on the base 1, and the guide rod 312 slides through the slide plate 323. The second driving member 321 can drive the screw transmission structure 322 to drive the slide plate 323 to slide along the first direction. The screw transmission structure 322 includes a screw and a nut seat, the screw is rotatably arranged on the base 1 along the first direction, and the screw is connected to the output shaft of the second driving member 321, the nut seat is sleeved on the screw and is threadedly connected to the screw, and the nut seat is connected to the slide plate 323, the second driving member 321 drives the screw to rotate to drive the nut seat to move along the first direction, and the threaded seat drives the slide plate 323 to move, the slide plate 323 drives the bearing platform 21 to move along the first direction through the guide rod 312, and the guide rod 312 slides through the slide plate 323, so that when the first driving member 311 drives the guide rod 312 to drive the bearing platform 21 to rise and fall, the guide rod 312 slides relative to the slide plate 323, thereby reducing the bearing burden of the guide rod 312 and the first driving member 311, avoiding deformation or damage after long-term operation, which is conducive to extending the service life. Preferably, the number of the screw transmission structures 322 is two, and the two screw transmission structures 322 are symmetrically arranged on the slide plate 323.

The first electrode 412 and the second electrode 422 cooperate to perform first point welding on the two brake resistors 5. The third driving member 423 then drives the second installation body 421 to drive the second electrode 422 away from the first electrode 412. The first driving member 311 drives the supporting platform 21 to move in the vertical direction until the first electrode 412 is aligned with the second point. The third driving member 423 then drives the second installation body 421 to drive the second electrode 422 to approach the first electrode 412 for second point welding. The above operation is repeated to complete multi-point welding of the brake resistor 5. The cooperation between the moving mechanism 3 and the welding structure enables multi-point welding of the brake circuit sheet, which can reduce the work intensity of the operators and improve the welding efficiency.

The limit groove 12 can not only limit the limit plate 424 when the second installation body 421 moves, but also has a guiding function, thereby improving the operation stability.

[0036] In addition, the brake resistor welding device further includes a control panel 6, which is disposed on the base 1 and is electrically connected to the first drive member 311, the second drive member 321, and the third drive member 423.
