[0022] The bearing mounting seat 4 is fixedly connected to the base 3 away from the box body 11. A slide groove 31 is provided in the middle of the upper end of the base 3, and two guide rails 32 are provided on both sides of the slide groove 31. The other end of the screw rod 5 is sleeved with a sliding sleeve 51 that can slide back and forth. The sliding sleeve 51 includes a driving sleeve 511 that can slide back and forth and is sleeved on the screw rod 5. A mounting sleeve 512 is sleeved on the driving sleeve 511. A slide table 6 is installed on the upper end of the mounting sleeve 512 and forms a sliding abutment with the slide groove 31. Two protrusions 61 are provided at opposite ends of the lower surface of the slide table 6. The two protrusions 61 respectively form sliding contact with opposite sides of the two guide rails 32. A ball groove 33 is provided between the protrusion 61 and the guide rail 32. A reciprocating ball 34 is installed in the ball groove 33. Two oil filling holes 62 connected to the ball groove 33 are also provided at the upper end of the slide table 6. A cover plug (not shown in the figure) is also provided on the oil filling hole 62. It is convenient to inject hydraulic oil through the oil filling hole 62, which is convenient to use.

[0023] A sensor assembly 7 is provided on the same side of the slide 6 and the base 3, and the sensor assembly 7 includes an L-shaped fixing plate 71 fixedly connected to the base 3, a PCB board 73 is installed on one end of the L-shaped fixing plate 71 by fasteners, and three opposing photoelectric sensors 74 are arranged on the upper end of the PCB board 73, and an L-shaped shielding plate 72 is also installed on the other end of the L-shaped fixing plate 71 by fasteners, and one end of the L-shaped shielding plate 72 is spaced from the slide 6 to prevent external dust or other objects from entering the sensor assembly 7, so as to avoid the false triggering of the opposing photoelectric sensors 74 by external dust or other objects, wherein the three opposing photoelectric sensors 74 are respectively opposing photoelectric sensors 74 at two end points and an opposing photoelectric sensor 74 at an origin, and for ease of understanding, the opposing photoelectric sensors 74 at the two end points are respectively a front end point sensor 741 and a rear end point sensor 743, and the opposing photoelectric sensor 74 at an origin is an origin sensor 742, and the origin sensor 742 is located between the front end point sensor 741 and the rear end point sensor 743;

[0024] Specifically, the fixing plate 75 is installed with a sensor sheet 76 by fasteners, and the sensor sheet 76 has three protrusions that form a signal cut-off transmission with the front end point sensor 741, the rear end point sensor 743 and the origin sensor 742. The three protrusions are the front end point protrusion 761, the origin protrusion 762 and the rear end point protrusion 763, and correspond to the front end point sensor 741, the origin sensor 742 and the rear end point sensor 743 to form a signal cut-off transmission. The front end point sensor 741 and the rear end point sensor 743 can effectively prevent the slide 6 from over-travel sliding. When the front end point protrusion 761 and the front end point sensor 741 form a sensor signal cut-off, or when the rear end point protrusion 763 and the rear end point sensor 743 form a sensor signal cut-off, the cut-off signal is transmitted to the control console, and the control console controls the motor 2 to stop rotating or reverse rotating, and the screw rod 5 stops or reverses rotating to drive the sleeve 51 to stop sliding or reverse sliding, thereby effectively stopping or reversely driving the slide 6 to slide, and effectively preventing the slide 6 from over-travel sliding.

[0025] Specifically, four ventilation observation holes 114 are provided on the box body 11 at the upper and lower ends of the motor 2 mounting hole 112. The ventilation observation holes 114 can be used for heat dissipation of the motor 2, observing the internal working conditions and adding hydraulic oil to the transmission wheel 21. Wire mounting holes 113 are provided on the other two opposite sides of the box body 11. The wire mounting holes 113 are used to install a wire mounting seat 1131. The wire mounting hole 113 on one side is installed with a wire mounting seat 1131 through fasteners. The wire mounting seat 1131 is provided with a power cord 1132 that is electrically conductive with the PCB board 73 and the motor 2. The end of the power cord 1132 has a power plug for connecting to an external power supply.

[0026] It should be supplemented that the “belt 22” mentioned above can be a transmission chain with a transmission effect, such as a “chain” and the like.

[0027] Working principle: The control console controls the motor 2 to drive the transmission wheel 21 to rotate, and the transmission wheel 21 drives the synchronous wheel 23 to rotate synchronously through the belt 22, and the synchronous wheel 23 drives the screw rod 5 to rotate, thereby driving the sliding sleeve 51 sleeved on the screw rod 5 to slide back and forth, thereby driving the slide 6 to slide back and forth on the base 3. When the slide 6 slides forward and approaches the overtravel, the front end point protrusion 761 will cut off the light signal of the front end point sensor 741, and transmit the front end point signal cut-off information to the control console, driving the control console to stop the rotation of the motor 2, so that the slide 6 stops sliding forward;

[0028] When the slide 6 slides backward and approaches the overtravel, the rear end point protrusion 763 cuts off the light signal of the rear end point sensor 743, transmits the rear end point signal cut-off information to the control console, drives the control console to stop the motor 2 from rotating, and thus stops the slide 6 from sliding backward;

[0029] When the slide 6 needs to return to the origin, the origin protrusion 762 will cut off the light signal of the origin sensor 742, transmit the origin signal cutoff information to the console, drive the console to stop the motor 2 from rotating, and thus stop the slide 6 at the origin position.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
