detailed description:

Embodiment: as shown in Fig. 1 to Fig. 3, a kind of plastic plate positioning mechanism comprises frame 10, and the left and right sides top surface of the top plate 11 of described frame 10 is fixed with support plate 12, and the two support plates 12 The top of the front end is fixed with an upper support plate 13, and the horizontal connecting plate 14 is fixed on the top surfaces of the two upper supporting plates 13. The middle part of the top surface of the horizontal connecting plate 14 is fixed with a plurality of compression cylinders 15, and the push rods of the compression cylinders 15 The end vertically passes through the horizontal connecting plate 14 and is fixed with a pressing plate 16;

The front and rear ends of the support plate 12 on the right side of the frame 10 are fixed with adjustment plates 121, and the two ends of the transmission screw 122 are hinged on the two adjustment plates 121, and one of the adjustment plates 121 is fixed with an adjustment motor 123. The output shaft of the motor 123 is a spline shaft, and the spline shaft is inserted into the spline hole provided at one end of the drive screw 122;

The moving plate 17 is located on the top plate 11 , and the moving plate 17 is located between the two support plates 12 . The right side of the moving plate 17 has an extension 171 extending to the right. The extension 171 is screwed into the drive screw 122 .

Further speaking, a scale 124 is fixed on the support plate 12 on the left or right side of the frame 10 .

Further, there are elongated grooves 125 on the inner side walls of the two support plates 12, semicircular sliders 172 are fixed on the left and right side walls of the moving plate 17, and the semicircular sliders 172 are inserted into the long Shaped groove 125.

Further, the bottom surface of the moving plate 17 has a plurality of spherical concave holes 173, the bottom surface of the moving plate 17 is fixed with a bottom plate 18, the bottom plate 18 has a plurality of tapered through holes 181, the upper end of the tapered through hole 181 The diameter is large, the diameter of the lower end of the tapered through hole 181 is small, the ball 19 is inserted into the spherical concave hole 173 and the corresponding tapered through hole 181, the lower end of the ball 19 protrudes from the bottom plate 18 and is pressed against the top plate of the frame 10 11 on.

Furthermore, the bottom surface of the pressing plate 16 has a friction plate 161 .

Working principle: the plastic plate is placed in the top plate 11 and between the two support plates 12. By adjusting the operation of the motor 123, the transmission screw 122 can be rotated to realize the movement of the moving plate 17, thereby pushing the plastic plate to move forward. The scale 124 is aligned with the plastic plate, so that the distance it moves forward can be adjusted. After moving to the required position, the adjustment motor 123 stops running, and then the push rod of the compression cylinder 15 is pushed down, so that the compression plate 16 Press against the plastic plate to achieve fixing, and the cutting machine can be used to cut along the front side of the top plate 11 of the frame 10, which is convenient for cutting;

Simultaneously, its moving plate 17 moves through the contact of ball 19 and semicircular slider 172, and its friction is little, reduces friction, improves service life.
