[0002] Automobile pedals include clutch pedals, brake pedals and accelerator pedals, which are mainly used to control the driving of the car and improve driving safety. Automobile pedals generally include a pedal body and a pedal arm. The pedal body can withstand the force when the driver steps on it. The pedal arm is used to connect with the corresponding components of the car to achieve different operational drives.

A positioning transmission slide 203 is provided on the surface of the positioning link 201. A positioning transmission column 204 is hingedly arranged on the L-shaped positioning plate 202. The positioning transmission column 204 is adapted to the positioning transmission slide 203. Two guide slides are symmetrically fixedly connected on the upper surface of the operating support platform 1. An adjusting support assembly 3 is slidably arranged between the two guide slides. The adjusting support assembly 3 comprises a horizontally movable U-shaped support platform 301. An adjusting support frame 302 that can move up and down is slidably arranged between the two inner side walls of the U-shaped support platform 301.

[0033] Furthermore, a clamping and positioning assembly 4 is fixedly connected to one side of the adjustment support frame 302, and the clamping and positioning assembly 4 includes a clamping support frame 401, and a clamping drive disk 402 is rotatably arranged inside the clamping support frame 401. The surface of the clamping drive disk 402 is symmetrically provided with an arc guide path 403, and the arc guide path 403 is an arc slide structure with one end close to the axis and the other end gradually away from the axis. Two L-shaped clamping plates 404 are symmetrically slidably arranged on one side of the clamping support frame 401, and the clamping surfaces of the two L-shaped clamping plates 404 are both made of elastic material. A clamping transmission column is fixedly connected to one side of the L-shaped clamping plate 404, and the clamping transmission column and the corresponding arc The L-shaped guide road 403 is slidably matched; the side of the clamping support frame 401 close to the L-shaped clamping plate 404 is fixedly connected to the welding assembly 5, and the welding assembly 5 includes two symmetrical and horizontally movable welding transmission platforms 501 and two symmetrically arranged limit baffles 502. The two welding transmission platforms 501 are respectively located at diagonal positions, and a plurality of welding adjustment connecting rods 503 are symmetrically rotatably connected to one side of the welding transmission platform 501.

As the welding transmission platform 501 continues to move horizontally, the transmission wheel 505 rolls along the limit baffle 502, the welding adjustment connecting rod 503 rotates, and the welding adjustment platform 504 moves in the vertical direction to perform vertical welding until the welding adjustment connecting rod 503 rotates to a vertical state, completing the vertical welding (such as Fig.11 shown).

At the same time, the adjusting driving gear 312 rotates synchronously with the adjusting transmission gear 311. Under the meshing action of the adjusting driving gear 312 and the clamping transmission rack 412, the clamping transmission rack 412 moves vertically, driving the T-shaped transmission plate 408 to slide along the inside of the adjusting slide groove. During the movement of the clamping transmission rack 412, the clamping transmission rack 412 is Under the meshing action of the transmission rack 412 and the clamping transmission gear 413, the clamping transmission gear 413 rotates, thereby driving the clamping drive disk 402 to rotate, and the arc guide path 403 moves synchronously with the clamping drive disk 402. Under the sliding cooperation between the arc guide path 403 and the clamping transmission column, the clamping transmission column drives the L-shaped clamping plate 404 to slide along the corresponding clamping slide 406, and the two L-shaped clamping plates 404 approach each other until the pedal arm is clamped and fixed (at this time, the first internal thread plate 306 is opposite to the second internal thread plate 307, and the two overlap up and down).

[0045] Then, the first electromagnet 313 is controlled to be powered off, and the magnetic attraction between the first electromagnet 313 and the first magnetic attraction plate disappears. Under the elastic recovery action of the first reset spring 316, the first telescopic rod 314 returns to its original length, and the adjustment transmission rack 315 and the adjustment drive gear 312 are meshed with each other. The second electromagnet 414 is energized. Under the magnetic attraction action of the second electromagnet 414 and the second magnetic attraction plate 415, the second reset spring 411 and the second telescopic rod 410 are compressed synchronously, and the clamping transmission rack 412 moves horizontally close to the U-shaped support seat 405, so that the meshing action between the clamping transmission rack 412 and the adjustment drive gear 312 disappears. Then, the two second drive motors are used to control The first transmission screw 304 and the second transmission screw 305 are controlled to rotate synchronously in the same direction, and the first internally threaded plate 306 and the second internally threaded plate 307 are synchronously moved horizontally. Under the meshing action of the first rack 308 and the second rack 309 and the adjusting transmission gear 311, the adjusting transmission gear 311 moves synchronously with the first internally threaded plate 306 and the second internally threaded plate 307, thereby driving the U-shaped support platform 301 to slide horizontally along the sliding guide rod 310, and driving the pedal arm to move synchronously horizontally until the pedal arm is opposite to the pedal (the first internally threaded plate 306 and the second internally threaded plate 307 are respectively located at the rightmost ends of the first transmission screw 304 and the second transmission screw 305, as shown in FIG. Figure 3 As shown), the adjusting support plate 303 is pushed by a pushing device so that the adjusting support plate 303 moves horizontally along the guide slideway, so that the pedal arm gradually approaches the pedal until one end of the pedal arm fits with the pedal.

[0046] For specific embodiment 3, please refer to Figure 11-13On the basis of specific embodiment 1 and specific embodiment 2, specifically, the welding assembly 5 also includes a welding support platform 506 fixedly connected to the clamping support frame 401, a clamping transmission port is provided on the surface of the welding support platform 506, an L-shaped clamping plate 404 is located inside the clamping transmission port, two welding guide grooves 507 are symmetrically provided on one side of the welding support platform 506, the welding transmission platform 501 slides with the corresponding welding guide grooves 507, an arc spring 508 is fixedly connected between the welding adjustment link 503 and the welding transmission platform 501, and a laser welding head 509 is fixedly installed on the side of the welding adjustment platform 504 away from the welding adjustment link 503.

[0047] Furthermore, a welding transmission rack 510 is fixedly connected to a side of the welding transmission platform 501 away from the welding adjustment connecting rod 503, and two welding transmission gears 511 are symmetrically rotatably connected to a side of the welding support platform 506 close to the welding transmission platform 501, and the welding transmission gears 511 are meshed with the corresponding welding transmission racks 510.

[0049] The operation process of this embodiment is as follows: when the pedal fits with the pedal arm (the fitting surface is a rectangular structure), the third drive motor is started to drive the welding drive gear 513 to rotate. Under the meshing action of the welding drive gear 513 and the transmission outer gear ring 407, the transmission outer gear ring 407 rotates. Under the meshing action of the transmission outer gear ring 407 and the welding adjustment gear 512, the two welding adjustment gears 512 rotate synchronously, thereby driving the welding drive gear 511 to rotate synchronously. Under the meshing action of the welding drive gear 511 and the corresponding welding drive rack 510, the welding drive platform 501 is driven to slide along the corresponding welding guide groove 507. The welding adjustment platform 504 drives the laser welding head 509 to move horizontally synchronously with the welding drive platform 501. During the horizontal movement of the two laser welding heads 509, the two horizontal sections where the pedal and the pedal arm fit together are welded until the transmission wheel 505 contacts the limit baffle 502, and the welding in the horizontal direction is completed; when the transmission wheel 505 contacts the limit baffle 502, the welding adjustment platform 504 stops moving horizontally, and as the welding transmission platform 501 continues to move horizontally, the transmission wheel 505 rolls in the vertical direction along the limit baffle 502, the welding adjustment link 503 rotates synchronously, and the arc spring 508 is stretched, so that the welding adjustment platform 504 drives the laser welding head 509 to move in the vertical direction to perform welding in the vertical direction, until the welding adjustment link 503 rotates to a vertical state, and the welding in the vertical direction is completed.

[0050] When welding is completed, the eccentric disk 207 is controlled to rotate in the opposite direction, the external force on the positioning link 201 is weakened, and the positioning link 201 gradually returns to the horizontal state. Under the connecting action of the positioning transmission column 204, the L-shaped positioning plate 202 rotates in the opposite direction, and the positioning link 201 and the L-shaped positioning plate 202 are synchronously moved away from the pedal, so that the pedal is loosened; the pushing device is used to pull the adjustment support plate 303, and the adjustment support plate 303 moves horizontally along the guide slide, driving the welded pedal to move horizontally away from the pedal positioning assembly 2, and then starting the second drive motor to drive the first drive screw 304 and the second drive screw 305 to rotate synchronously in the same direction, the first internal threaded plate 306 and the second internal threaded plate 307 move horizontally in the same direction, and the second drive motor moves in the opposite direction, and the U-shaped support table 301 moves horizontally synchronously (that is, moves to the right, such as Figure 3 As shown), the pedal after welding is driven to move; the first transmission screw 304 and the second transmission screw 305 are driven by the second drive motor to move in the opposite direction synchronously, so that the first internal thread plate 306 and the second internal thread plate 307 move in the opposite direction synchronously (the first internal thread plate 306 moves to the left, and the second internal thread plate 307 moves to the right, as shown in FIG. Figure 3As shown), the first rack 308 and the second rack 309 move synchronously in opposite directions. Under the meshing action of the first rack 308 and the second rack 309 and the adjusting transmission gear 311, the adjusting transmission gear 311 rotates, thereby driving the adjusting drive gear 312 to rotate. Under the meshing action of the adjusting drive gear 312 and the adjusting transmission rack 315, the adjusting transmission rack 315 moves upward, driving the adjusting support frame 302 to move upward synchronously, thereby causing the welded pedal to move upward synchronously until it corresponds to the external collection device.

[0051] The second electromagnet 414 is controlled to be powered off, and the first electromagnet 313 is powered on, so that the clamping transmission rack 412 is synchronously meshed with the clamping transmission gear 413 and the adjusting drive gear 312, and the second drive motor is used to drive the first transmission screw 304 and the second transmission screw 305 to move synchronously in the opposite direction, so that the first internal thread plate 306 and the second internal thread plate 307 move synchronously in the opposite direction (the first internal thread plate 306 moves to the right, and the second internal thread plate 307 moves to the left, as shown in FIG. Figure 3 As shown), the adjusting transmission gear 311 is driven to rotate in the opposite direction, and the clamping transmission rack 412 is moved in the opposite direction, so that the clamping transmission gear 413 drives the clamping drive disk 402 to rotate in the opposite direction synchronously, and the L-shaped clamping plates 404 move away from each other, and the welded pedal is released, and the welded pedal falls into the collection device; then the second electromagnet 414 is controlled to be energized, and the first electromagnet 313 is powered off, and the adjusting transmission rack 315 is meshed with the adjusting drive gear 312, and the second drive motor is started to drive the first transmission screw 304 and the second transmission screw 305 to move in the opposite direction synchronously, so that the first internal thread plate 306 and the second internal thread plate 307 move in the opposite direction synchronously (the first internal thread plate 306 continues to move to the right, and the second internal thread plate 307 continues to move to the left, as shown in FIG. Figure 3 As shown), under the meshing action of the adjustment transmission rack 315 and the adjustment drive gear 312, the adjustment support frame 302 is driven to move downward until the first internal thread plate 306 is located at the rightmost end, the second internal thread plate 307 is located at the leftmost end, and the L-shaped clamping plate 404 corresponds to the next pedal arm to be welded (the next pedal arm is opposite to the middle position of the two L-shaped clamping plates 404).
