A limiting plate 173 is provided between the bottoms of the two guide rods 172. An elastic member 174 is sleeved on the guide rod 172, and the elastic member 174 is a compression spring. One end of the elastic member 174 is connected to the limit plate 173, and the other end of the elastic member 174 is connected to the fixed plate 171.

Elastic sheets 183 are arranged at intervals on the vertical side walls of the material discharge inclined plate 182.
[0031] When it is necessary to cut the linear guide rail, the staff inputs the required cutting length of the guide rail through the control panel 14. The control panel 14 controls the stepper motor 45 to drive the gear 46 to rotate, and the gear 46 drives the rack 44 to rotate, so that the moving plate 42 moves to the right. When the encoder on the motor shaft of the stepper motor 45 detects the rotation angle and number of turns and other information, it is converted into an electrical signal and fed back to the controller in the control panel 14. The controller accurately calculates the moving distance of the moving block based on the data fed back by the encoder. When the preset value input on the control panel 14 is reached, the controller controls the stepper motor 45 to stop rotating, and at the same time controls the fourth cylinder 48 to drive the limiting block 49 to move downward. The limiting block 49 contacts the ground to complete the fixation of the moving block. Then the staff places the linear guide between the electric slider 32 and the transmission roller 12, and then starts the second cylinder 34 through the control panel 14. The second cylinder 34 drives the first push block 35 to squeeze and clamp the linear guide to the rear side, and the rear side wall of the linear guide contacts the guide wheel 20. The control panel 14 inputs a command to control the electric slide 31 to drive the electric slider 32 to move to the right, and then the first push block 35 cooperates with the guide wheel 20 to drive the linear guide to move to the right until it contacts the grinding belt 473. Due to the pressure sensor in the positioning block 475, the electric slide 31 is driven to move to the right. The device detects the pressure and transmits the signal to the controller in the control panel 14. The controller controls the electric slide 31 to stop moving and starts the third cylinder 15 to drive the second push block 16 to move backward. The second push block 16 on the left squeezes the linear guide rail and contacts the rear side wall of the feed trough 2 of the machine tool 1 to complete the fixation. The second push block 16 on the right squeezes the linear guide rail and contacts the limit plate 173 to complete the fixation. By controlling the rotation motor 474 to work, the rotation motor 474 drives the rotation roller 472 to rotate, and then the grinding belt 473 rotates to grind the end of the linear slide rail. The controller of the control panel 14 controls the driving motor 11 to drive the cutting knife 10 to rotate, and the first cylinder 8 drives the sliding plate 7 to move forward, so that the cutting knife 10 cuts the linear guide rail, and the suction pump 19 sucks the exhaust gas and guides it out through the upper external air collecting pipe. At the same time, a cooling pipe can be installed on the tool housing 9, and coolant is introduced through the external pipeline to prevent the blade from overheating during cutting. After the cutting is completed, the driving motor 11 is controlled to stop working, and the first cylinder 8 drives the sliding plate 7 to move backward. When the inclined rod 177 on the tool housing 9 squeezes the round shaft 176, the round shaft 176 passes through the connecting rod 175 The limit plate 173 is driven to move upward, and the elastic member 174 is compressed. At this time, the third cylinder 15 on the right is controlled to drive the second push block 16 to continue to move backward, and then the cut linear guide rail is pushed onto the material dumping inclined plate 182. The material dumping inclined plate 182 moves with the moving plate 42, and can just receive the cut linear guide rail. When the linear guide rail slides up and down on the material dumping inclined plate 182, the elastic sheet 183 can play a buffering role. Then the two third cylinders 15 are controlled to drive the second push block 16 to reset, and then the feeding assembly 3 can move to the right to feed the material for the next cutting operation.
