In this embodiment, the bottom of the moving platform 3 is provided with a connecting block 33. The first driving part 2 is a motor screw structure or a cylinder structure. If it is a cylinder structure, the cylinder is mounted on the front end of the base 1, and the output end of the cylinder is connected to the connecting block 33 at the bottom of the moving platform 3. If it is a motor screw structure, the screw is mounted inside the base 1, and the connecting block 33 of the moving platform 3 can move back and forth on the screw. The motor is mounted on the front end of the base 1, and the output end of the motor is connected to the screw.

When the workpiece is fixed by the pressure block 55, the pressure block 55 can be moved up and down by rotating the second screw 582 to press the fixing component. When the workpiece is clamped by the push plate 56 and the arc-shaped clamping member 57, after adjusting the position of the slider 4, the mounting blocks 51 corresponding to the front and rear fixing components 5 are pushed so that the mounting blocks 51 slide back and forth on the guide rod 584. After the front and rear push plates 56 or the front and rear arc-shaped clamping members 57 clamp the workpiece, the two first nuts 583 are twisted so that the two first nuts 583 come closer to each other and abut against the front and rear sides of the mounting block 51, thereby clamping and fixing the mounting block 51 so that it cannot move, which is convenient and quick.

[0034] like Figure 1-3As shown, the rotating plate 54 is provided with multiple adjustment holes 541, which are evenly spaced. The second screw 582 is detachably installed in the adjustment holes 541. In this embodiment, the rotating plate 54 is provided with three adjustment holes 541 along the front-rear direction. The top of the pressure block 55 is detachably installed to the bottom of the second screw 582 through a threaded connection structure. When adjustment is required, first rotate the pressure block 55 to remove it from the bottom of the second screw 582, then rotate the second screw 582 to remove it from the rotating plate 54, and then select the desired adjustment hole 541 to rotate and install it, thereby achieving the purpose of adjusting the position of the second screw 582. This allows for adjustment of the pressing position of the pressure block 55, making it suitable for different fixing scenarios and further improving the versatility of the mechanical and electrical positioning device.

In this embodiment, one end of the third screw 591 is installed on the top surface of the support plate 53, and the rotating plate 54 is installed on the third screw 591 through the adjusting groove 542, so that the third screw 591 is located in the adjusting groove 542. The rotating plate 54 can move along the length direction of the adjusting groove 542. After moving, it is locked and fixed with the third nut 593, thereby realizing the position adjustment of the pressure block 55, the push plate 56 or the arc-shaped clamping block 57, realizing a larger adjustment range and more adjustment methods, applicable to more different fixing scenarios, and further improving the versatility of the mechanical and electrical positioning device.

[0036] like Figure 1 and Figure 3As shown, the limiting component 6 includes a third driving part 61 and an anti-detachment clamping block 62. The anti-detachment clamping block 62 is movably installed on the moving platform 3, and the third driving part 61 is installed on the moving platform 3.

In this embodiment, the third driving part 61 is a cylinder or an electric telescopic rod. There are two third driving parts 61 and two anti-detachment clamping blocks 62. The two third driving parts 61 are respectively installed on the left and right sides of the moving platform 3, and the two anti-detachment clamping blocks 62 are installed on the top surface of the front and rear sides of the moving platform 3. During operation, after the workpiece is fixed by the fixing component 5, the two third driving parts 61 drive the two anti-detachment clamping blocks 62 to move closer to each other, thereby limiting the workpiece and preventing it from moving during processing, which is beneficial to improving the processing quality of the workpiece.

[0037] like Figure 1 and Figure 3 As shown, the system also includes rotating rollers 8. Multiple rotating rollers 8 are respectively installed on the top of the left and right sides of the base 1, and the top of each rotating roller 8 can abut against the moving platform 3. In this embodiment, multiple driven rotating rollers 8 are installed on the top surface of the left and right sides of the base 1, and the moving platform 3 abuts against the top of the rotating rollers 8. During the movement of the moving platform 3, the rotating rollers 8 help improve the smoothness of the movement of the moving platform 3 and avoid jamming or stuttering.

[0038] like Figure 1 and Figure 3 As shown, it also includes a buffer rod 91, an elastic element 92, and a buffer pad 93. One end of the elastic element 92 is installed at the rear end of the base 1, and the other end of the elastic element 92 is installed at one end of the buffer rod 91. The other end of the buffer rod 91 is installed at the buffer pad 93, which can abut against the moving platform 3. In this embodiment, the elastic element 92 is a spring. The elastic element 92 is installed on the inner wall of the rear end of the base 1. During operation, after the workpiece is placed and fixed, the first driving unit 2 drives the moving platform 3 to move backward until the connecting block 33 of the moving platform 3 abuts against the buffer pad 93. At this time, the buffer pad 93 compresses the elastic element 92 through the buffer rod 91, thereby achieving the function of shock absorption and buffering. This not only prevents the moving platform 3 from colliding with the inner wall of the base 1 due to excessive movement and causing damage, thus improving its service life, but also prevents the fixed workpiece from being misaligned due to collision and vibration, affecting subsequent processing.
