[0025] Furthermore, a mounting block 210 is mounted on the upper end of the slider 209, a connecting plate 211 is mounted on one side surface of the mounting block 210, a clamp 212 is mounted on the side of the connecting plate 211, and a connecting bolt 213 is mounted on one side surface of the mounting block 210. By setting the slider 209, the mounting block 210, the connecting plate 211, the clamp 212 and the connecting bolt 213, when the clamp 212 needs to be replaced, only the connecting bolt 213 needs to be removed to disconnect the connecting plate 211 and the clamp 212 from the mounting block 210. This design simplifies the process of replacing the clamp 212, saves time and improves production efficiency.

[0026] Furthermore, two groups of cylinders 201 are provided, and are symmetrically arranged with respect to the central axis of the base 1. The support plate 202 forms a telescopic structure with the base 1 through the cylinders 201. Through the arrangement of the cylinders 201 and the support plate 202, the two groups of cylinders 201 are evenly distributed on both sides of the machine or equipment. This symmetrical arrangement can improve the structural balance and stability of the machine, reduce vibration and unstable movement caused by eccentricity or imbalance, and avoid displacement caused by shaking of the workpiece during lifting.

[0027] Furthermore, two groups of sliders 209 are provided, and the threads of one group of sliders 209 are set in opposite directions. Through the setting of the sliders 209, the motor 206 drives the threaded rod 207 to rotate, and the threaded rod 207 drives the slider 209 to move through the surface bolts. The slider 209 can be moved inward by one positive and one negative.

[0028] Furthermore, the clamp 212 is fixed to the mounting block 210 through the connecting plate 211 and the connecting bolts 213, and the clamping surface of the clamp 212 is made of rubber material. Through the arrangement of the slider 209, the mounting block 210, the connecting plate 211, the clamp 212 and the connecting bolts 213, the clamping surface of the clamp 212 is made of rubber material, which has good anti-slip and buffering properties.

[0029] Furthermore, the measuring end of the laser ranging sensor 4 is facing the mounting plate 203, and the laser ranging sensor 4 is connected to the motor 206 through the controller 5. Through the setting of the motor 206, the laser ranging sensor 4 and the controller 5, the laser ranging sensor 4 detects the distance to the workpiece, and after detecting the appropriate distance, the motor 206 is started through the controller 5. The laser technology has high measurement accuracy and stability, which can ensure the accuracy of the measurement results and avoid unstable clamping that may cause damage to the workpiece.

[0030] Furthermore, the pressure sensor 6 is connected to the motor 206 through the controller 5, and the pressure sensor 6 is connected to the clamp 212 through the connecting plate 211. When clamping, the force exerted on the clamp 212 is transmitted to the connecting plate 211, and the connecting plate 211 applies pressure to the pressure sensor 6. After the pressure sensor senses a certain pressure, the motor 206 is turned off through the controller 5 to avoid damage to the workpiece due to excessive pressure.

[0031] Furthermore, the dust collecting mechanism 7 includes a box body 701, a handle 702, a filter 703, a telescopic tube 704, a suction nozzle 705, a vent 706 and an exhaust fan 707. The box body 701 is installed inside the base 1, the handle 702 is installed outside the box body 701, the filter 703 is installed inside the box body 701, the telescopic tube 704 is installed at the upper end of the inner part of the base 1, the suction nozzle 705 is installed at the upper end of the telescopic tube 704, a vent 706 is opened on one side of the box body 701, and an exhaust fan 707 is installed at one end of the vent 706. 702, filter screen 703, telescopic tube 704, suction nozzle 705, vent 706 and exhaust fan 707 are arranged. When cleaning, the exhaust fan 707 is turned on first. The exhaust fan 707 draws air into the box body 701 through the vent 706, and then the air is introduced into the box body 701 through the suction nozzle 705 at one end of the telescopic tube 704. When the air is introduced, the suction nozzle 705 is moved to the and position through the telescopic tube 704 to clean the surface of the device. The sucked waste is collected through the filter screen 703 and cleaned through the surface of the device to avoid long-term accumulation of waste and damage to the device during use.

[0032] Furthermore, the box body 701 forms a telescopic structure with the base 1 through the handle 702, and the filter 703 fits tightly with the box body 701. Through the arrangement of the box body 701, the handle 702 and the filter 703, after a long period of cleaning, waste accumulates on the filter 703. The box body 701 can be pulled out through the handle 702, and then the filter 703 inside the box body 701 can be cleaned to complete the cleaning.

[0033] Working principle: When in use, first place the workpiece on the upper end of the mounting plate 203. After the laser distance measuring sensor 4 measures and controls the appropriate clamping distance with the workpiece, the controller 5 starts the motor 206 to rotate, and the motor 206 drives the threaded rod 207 to rotate. The threaded rod 207 drives the slider 209 with a positive and negative surface to move inward. The slider 209 carries the clamp 212 to clamp the workpiece. When clamping again, the rubber layer on the surface of the clamp 212 protects the workpiece. The continuous inward clamping force is transmitted to the connecting plate 211 through the clamp 212. The connecting plate 211 applies pressure to the pressure sensor 6. After the pressure sensor 6 is subjected to a certain pressure, the motor 206 is turned off through the controller 5 to avoid excessive clamping force. During the clamping process, if the height of the workpiece is not appropriate, the cylinder 201 is adjusted, and the cylinder 201 drives the support plate 202, and the support plate 202 drives the mounting plate 203 to move up and down, so that the workpiece reaches the appropriate height. Working height, when clamping, if the clamp 212 is not suitable, the connecting plate 211 and the clamp 212 are removed from the upper end of the mounting block 210 by removing the connecting bolts 213, and then the suitable clamp 212 is replaced for installation. After the workpiece is processed, when the surface of the device is cleaned, the exhaust fan 707 is started, and the exhaust fan 707 generates negative pressure to the inside of the box 701 through the vent 706, and then the suction nozzle 705 is moved to a suitable position through the telescopic tube 704. The negative pressure inside the box 701 sucks air inward through the suction nozzle 705 at one end of the telescopic tube 704, and the air doped with waste is sucked into the box 701 through the telescopic tube 704. Then the filter 703 filters the fine waste in the air. After cleaning, the box 701 is pulled out through the handle 702, and then the filter 703 is removed from the inside of the box 701 for cleaning. In this way, the use process of the automatic positioning and tightening device for triangular locks is completed.
