DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown, an embodiment of the utility model proposes a tool for metal plate welding, which is used to clamp two metal plates 500 respectively during the processing of the metal plates 500 and keep the two metal plates 500 spliced ​​in a T-shaped state, so as to facilitate welding the two metal plates 500 into a T-shaped workpiece.

[0024] Please refer to Figure 1 , Figure 2 and Figure 4The metal sheet welding tool includes a base 100, on which two clamping units 200 are arranged at intervals, and the clamping units 200 respectively include two clamping components 300 arranged at intervals, and the clamping components 300 are used to clamp the metal plate to be welded to position the metal plate, and the two clamping components 300 in one of the clamping units 200 are arranged at intervals along a first direction, and the two clamping components 300 in the other clamping unit 200 are arranged at intervals along a second direction, so that the two metal sheets 500 respectively clamped by the two clamping units 200 are perpendicular to each other and spliced ​​into a T shape, and in this embodiment, the first direction is the X-axis direction, and the second direction is the Y-axis direction. The clamping assembly 300 includes a mounting plate 301 that matches the base 100, and two rotatable rotating rods 302 are symmetrically arranged on the mounting plate 301. The ends of the two rotating rods 302 are rotatably connected to clamping plates 303 and the two clamping plates 303 are symmetrically arranged. The clamping assembly 300 also includes a wedge block 304 that is movably arranged on the mounting plate 301, and the opposite sides of the wedge block 304 are respectively in one-to-one correspondence with one end of the two rotating rods 302 away from the clamping plates 303. The clamping unit 200 also includes a transmission connection with the wedge block 304 The driving component 400 is connected, and when the driving component 400 drives the wedge block 304 to move on the mounting plate 301, the wedge block 304 drives the two rotating rods 302 to rotate synchronously to make the two clamping plates 303 approach each other. After the metal sheet 500 to be clamped is placed in the space between the two symmetrical clamping plates 303, the wedge block 304 drives the rotating rod 302 to rotate until the two clamping plates 303 respectively abut against the opposite sides of the metal sheet 500, so that the metal sheet 500 can be clamped, thereby fixing the position of the metal sheet 500 on the base 100.

[0025] Specifically, the operation steps of welding the metal sheet 500 using the metal sheet welding tool provided in this embodiment are as follows: first, a metal sheet 500 is placed in one of the clamping units 200, and the metal sheet 500 is placed between the two clamping plates 303 in the same clamping assembly 300, and the driving assembly 400 is started to drive the wedge block 304 to move so that the two rotating rods 302 rotate under the drive of the wedge block 304, and with the movement of the rotating rod 302, the two clamping plates 303 move in the direction close to the metal sheet 500 until the two clamping plates 303 respectively abut against the opposite sides of the metal sheet 500, at which time the clamping assembly 300 clamps the metal sheet 500 and makes The metal sheet 500 is kept vertical on the base 100, and then another metal sheet 500 is placed in another clamping unit 200 and the two metal sheets 500 are spliced ​​into a T shape. Repeat the above steps to clamp the metal sheet 500, and the two metal sheets 500 can be fixed on the base 100 respectively and the two metal sheets 500 can be kept spliced ​​in a T shape. At this time, the two metal sheets 500 can be welded. After the welding is completed, the driving assembly 400 is started to move the wedge block 304 in the opposite direction. At this time, the rotating rod 302 can rotate in the direction of moving the two clamping plates 303 away from each other, so that the clamping assembly 300 can release the clamping of the metal sheet 500 and take out the welded T-shaped workpiece. The metal sheet welding tool provided in this embodiment simplifies the clamping operation steps of the metal sheet 500, and the clamping operation is simple, and it is convenient to take out the welded workpiece, which is conducive to improving the processing efficiency of the metal sheet 500.

[0026] like Figure 2 and Figure 3 As shown, two first rotating shafts 305 are arranged on the mounting plate 301 at intervals, and first mounting holes 306 matching the first rotating shafts 305 are respectively arranged on the two rotating rods 302, and the two rotating rods 302 are respectively matched with the two first rotating shafts 305 in a one-to-one correspondence. The first rotating shafts 305 are arranged on the mounting plate 301 for the rotating rods 302 to be installed, so that the rotating rods 302 can rotate smoothly relative to the mounting plate 301, and it is convenient to install the rotating rods 302 on the mounting plate 301, so as to facilitate the assembly of the tooling for metal plate welding.

[0027] Please combine Figure 2 and Figure 3, the rotating rods 302 are respectively provided with second rotating shafts 307, and the clamping plates 303 are respectively provided with second mounting holes 308 matched with the second rotating shafts 307. The second mounting holes 308 are provided on the clamping plates 303 to match with the second rotating shafts 307 on the rotating rods 302, so as to realize the rotational connection between the clamping plates 303 and the rotating rods 302, so that the clamping plates 303 can rotate and fit with the surface of the metal sheet 500 during the process of clamping the metal sheet 500, ensuring that the position of the metal sheet 500 between the two symmetrical clamping plates 303 remains stable, which is conducive to improving the reliability of the tooling for metal sheet welding.

[0028] In detail, the base 100 is provided with an arc groove 101 for the second rotating shaft 307 to pass through, and the center of the arc groove 101 is located on the axis of the second rotating shaft 307. When the rotating rod 302 rotates on the mounting plate 301, the second rotating shaft 307 slides in the arc groove 101, so that the movement direction of the rotating rod 302 is limited by the cooperation between the arc groove 101 and the second rotating shaft 307, and the rotating rod 302 is prevented from deviating from the preset direction when moving, so that the clamping plate 303 can stably contact the surface of the metal plate 500, thereby improving the stability of the metal plate welding tool during operation.

[0029] like Figure 3 As shown, the mounting plate 301 is further provided with a guide seat 309, the guide seat 309 is provided with a guide hole 310, and the wedge block 304 is provided with a guide rod 311 matched with the guide hole 310, and the axial direction of the guide hole 310 is consistent with the moving direction of the wedge block 304. In order to prevent the wedge block 304 from unexpectedly deviating when moving, the moving direction of the wedge block 304 is limited by the guide hole 310 provided on the guide seat 309, and the wedge block 304 is provided with a guide rod 311 matched with the guide hole 310, and the guide rod 311 slides in the guide hole 310 when the wedge block 304 moves, so as to ensure that the wedge block 304 moves in a preset direction and prevent the wedge block 304 from detaching from the mounting plate 301 when moving.

[0030] Please refer to Figure 2 and Figure 3The driving assembly 400 includes a motor 401 arranged on the base 100 and a screw rod 402 arranged at the output end of the motor 401. The screw rod 402 is rotatably arranged on the base 100 and the axial direction of the screw rod 402 is consistent with the moving direction of the wedge block 304. The end of the guide rod 311 away from the wedge block 304 is provided with a transfer block 312, and the transfer block 312 is provided with a threaded hole 313 that matches the screw rod 402. When the screw rod 402 rotates under the drive of the motor 401, the adapter block 312 can be driven to move along the axial direction of the screw rod 402 and drive the wedge block 304 to move through the cooperation between the screw rod 402 and the threaded hole 313, and the travel of the wedge block 304 can be adjusted by controlling the number of turns of the screw rod 402 to control the rotation angle of the rotating rod 302 and the moving distance of the clamping plate 303, so as to control the spacing between the two symmetrical clamping plates 303 and the thickness of the metal sheet 500, so that the metal sheet welding tool can clamp a variety of plates with different thicknesses, thereby improving the versatility of the metal sheet welding tool, and the moving direction of the wedge block 304 can be adjusted by controlling the rotation direction of the screw rod 402 through the motor 401, so that the clamping assembly 300 can automatically clamp or release the metal sheet 500, thereby facilitating the use of the metal sheet welding tool.

[0031] In this embodiment, the two clamping assemblies 300 in the same clamping unit 200 are symmetrically arranged, and the screw rod 402 is provided with two threaded portions 403 with opposite rotation directions at intervals, and the two threaded portions 403 are matched with the threaded holes 313 on the adapter blocks 312 in the two clamping assemblies 300 in a one-to-one correspondence. The two clamping assemblies 300 in the same clamping unit 200 are driven by the same driving assembly 400, and when the screw rod 402 rotates, the two threaded portions 403 with opposite rotation directions respectively drive the two wedge blocks 304 in the two clamping assemblies 300 to move in opposite directions, so that the two clamping assemblies 300 clamp or release the metal sheet 500 at the same time, further improving the working efficiency of the tooling for metal sheet welding.

[0032] like Figure 3As shown, the clamping assembly 300 further includes a tension spring 314, the opposite ends of which are respectively matched with the ends of the two rotating rods 302 away from the clamping plates 303, and the tension spring 314 drives the ends of the two rotating rods 302 away from the clamping plates 303 to approach each other and drive the two clamping plates 303 away from each other. In the process of moving the wedge block 304 to make the clamping plates 303 clamp the metal plate, the tension spring 314 is stretched as the rotating rod 302 rotates, and when the wedge block 304 is moved in the reverse direction to release the locking of the metal plate 500, the tension spring 314 gradually restores its original length and pulls the two rotating rods 302 to rotate, at which time the clamping plates 303 are driven by the rotating rod 302 to move away from the metal plate 500, so that the clamping plates 303 are automatically separated from the metal plate 500, thereby facilitating the removal of the welded workpiece.

[0033] Specifically, the two ends of the tension spring 314 are provided with hooks 315, and the two rotating rods 302 are provided with connecting rods 316, and the two hooks 315 are matched with the two connecting rods 316 in a one-to-one manner. By providing the hooks 315 at the opposite ends of the tension spring 314 to match the connecting rods 316 on the rotating rod 302, it is ensured that the tension spring 314 and the rotating rod 302 are matched reliably, and the tension spring 314 is prevented from being loosened from the rotating rod 302 during the movement of the rotating rod 302.

[0034] Please refer to Figure 3 and Figure 4 The clamping plates 303 are provided with buffer pads 317, respectively, and the buffer pads 317 cover the sides of the two symmetrically arranged clamping plates 303 that are close to each other. When the clamping plates 303 clamp the metal plate 500, the buffer pads 317 are in direct contact with the metal plate 500. The buffer pads 317 are made of soft materials such as silica gel and foam, so as to prevent the surface of the metal plate 500 from being scratched by the clamping plates 303 during processing, thereby ensuring that the processed workpiece has good quality.
