Background
Automotive seat rails are assemblies that connect an automotive seat to the underbody of a vehicle, which allows the seat to move back and forth within the vehicle to adjust the seating position of the occupant and the driving position of the driver. These rails are typically made of metal and have strength and durability to withstand the weight and pressure of the passengers moving within the vehicle. The track system typically includes a locking mechanism to ensure that the seat remains stable and safe in the selected position. The processing of the seat guide rail mainly comprises the processes of cutting raw materials, rough processing such as forming of the cut materials, fine processing such as punching and threading, subsequent heat treatment, surface treatment and the like.
The Chinese patent publication No. CN107322073B discloses a guide rail cutting device for a guide rail production line, and the guide rail cutting device mainly drives a cutting knife to move up and down through cam rotation, so that the guide rail is cut, and the guide rail is limited through a limiting roller during cutting, so that the guide rail is prevented from shaking during cutting, and the smoothness of a cutting surface is ensured. It still has the following drawbacks:
1. The limiting roller is far from the cutting position during cutting, so that the end surface of the material can be slightly pulled and deformed towards the cutting surface during cutting, and the deformation is usually caused by cutting force and stress generated during cutting;
2. The guide rail in the technical proposal is conveyed only by the guide roller and the conveying device, and no guide structure is used for ensuring the state of the guide rail during cutting.
Therefore, it is necessary to provide an automatic processing device for automobile seat guide rails and a processing method thereof, which can achieve the function of automatically cutting workpieces to fixed lengths.

It should be further noted that, when the two side worms 441 are driven to rotate in the same direction, the middle worm wheel 442 does not rotate, but moves vertically under the action of the two side worms 441, when the worm wheel 442 moves down to the bottom end of the mounting bracket 444 to contact the second fixing plate 41, the lower contact sensor is triggered, at this time, the axle contacts the end of the connecting portion 431, the PLC controller immediately starts the electric suction cup 432, so that the axle and the connecting portion 431 are connected into a whole by suction, then, by controlling the two side worms 441 to rotate reversely, the middle worm wheel 442 starts to rotate, so as to drive the bidirectional screw 43 to rotate synchronously, the two adjusting seats two 42 on the limiting mechanism two 4 move synchronously and oppositely along with the rotation of the bidirectional screw 43, and after the limiting rollers on the two sides are adjusted to be in place, the PLC controller immediately stops the rotating motor two, and along with the movement of the adjusting seat two 42, the adjusting seat two 32 on the other side slides synchronously along the guide shaft 33 under the action of the connecting rod, stops moving simultaneously when the limiting seat two stops, and then one end of the workpiece is manually fed from the right side of fig. 1 to the second conveying mechanism 2.

When the position of the limiting roller is adjusted, firstly, in the initial state, the electric telescopic rod 45 is started by the PLC controller to enable the output shaft of the electric telescopic rod 45 to extend to the longest so that the driving gear 443 is horizontally moved out and is not meshed with the transmission gears 231 on the two sides, meanwhile, the PLC controller starts the built-in power supply I to enable the electromagnet I224 to enter the working state so as to stabilize the mounting shaft 223 and enable the transmission gears 231 on the two sides to be unable to rotate, then, the worm gear 442 starts to move downwards from the initial state by controlling the worm 441 on the two sides to rotate clockwise, and when the contact sensor I on the bottom wall of the mounting frame 444 is triggered, the wheel shaft moves to one side of the connecting part 431 and contacts with the contact sensor I, and the PLC controller immediately starts the built-in power supply II in the connecting part 431 so that the connecting part 431 and the wheel shaft are connected into a whole through suction force, thereby being convenient for adjusting the position of the limiting roller;
After the adjustment, the control of the built-in power supply II is disconnected by the PLC controller, so that the suction force between the connecting part 431 and the wheel shaft disappears, at this time, the PLC controller controls the rotating motor II to reset, then, the worm 441 is continuously driven reversely after the reset, so that the worm wheel 442 starts to move upwards, when the contact sensor I on the top wall of the mounting frame 444 is triggered, the worm wheel 442 moves to the initial position, at this time, the PLC controller turns off the electric telescopic rod 45, so that the output shaft of the electric telescopic rod is retracted and reset, and the horizontal back driving gear 443 is just meshed with the transmission gears 231 on two sides again, after the electric telescopic rod 45 is reset, the PLC controller immediately disconnects the control of the built-in power supply I (namely, turns off the built-in power supply I), so that the suction force between the electromagnet I224 and the mounting shaft 223 disappears at this time.
In the whole process of changing the driving gear 443, the horizontal displacement motion of the driving gear 443 only occurs in the initial state and returns to the initial position, and the vertical displacement motion of the worm wheel 442 is realized by the forward and reverse rotation of the worm 441, and the movement distance is the same, so that the position of the driving gear 443 in the initial state is consistent with the position of the driving gear 443 when the driving gear is returned to the initial position, and the problem of tooth striking of the driving gear 231 does not occur.
