[0047] Working principle:

[0048] When cutting for electrical parts production:

[0049] Fixation process:

[0050] The present invention is aimed at cutting plate-shaped electrical parts. The plate is placed on the surface of the multiple groups of rotating rods 12 on the surface of the horizontal plate 13, and one side of the plate is made to fit with the protruding portion of the surface of the horizontal plate 13. At the same time, under the action of the first torsion spring 903, the straight plate 905 can drive the roller 904 to fit with the surface of the plate, so that the side of the plate close to the cutting machine body 15 exceeds the specified distance from the edge of the horizontal plate 13. The cylinder 202 is controlled to work, so that the telescopic end of the cylinder 202 is extended to drive the triangular block 206 to move synchronously, so that the triangular block 206 can push the crossbeam 205 to move downward, so that the crossbeam 205 drives the sleeves 209 on both sides to move downward synchronously, so that the sleeves 209 on both sides can drive the circular plate 203 to move downward. At the same time, the springs 208 on both sides can be compressed, so that the circular plate 203 can drive the threaded rod 21 to move downward synchronously through the semicircular plate 11, so that the threaded rod 21 can drive the pressure plate 22 to press against the surface of the plate, so that the plate can be pressed. At the same time, the second motor 10 is controlled to work, so that the output shaft of the second motor 10 rotates to drive the screw 7 to rotate, so that the screw 7 can drive the slider 20 to move, so that the slider 20 can drive the cross plate 13 to move synchronously, so that the cross plate 13 drives the plate to move toward the saw disk of the cutting machine body 15, and the cutting machine body 15 is controlled to work so that the saw disk of the cutting machine body 15 rotates so that the saw disk can cut the plate. After complete cutting, the second motor 10 is stopped.

[0051] Adjustment process:

[0052] When it is necessary to fix plates of different thicknesses, the operator rotates the disc 4 through the handles 5 on both sides so that the disc 4 can drive the threaded rod 21 to rotate synchronously, so that the threaded rod 21 drives the pressure plate 22 to move upward, so that the pressure plate 22 is away from the plate, and the telescopic end of the cylinder 202 is controlled to extend to the limit position, so that the disc 203 moves downward to the limit position. According to the above operation, the disc 4 is rotated in the opposite direction to make the pressure plate 22 fit with the surface of the plate to complete the fixation of plates of different thicknesses. The width of the plate needs to be close to the length of the rotating rod 12 to prevent the plate width from being too large and unable to be stably fixed.

[0053] Loading process:

[0054] After a cut is completed, according to the above operation, the telescopic end of the cylinder 202 is shortened so that the pressing plate 22 is no longer pressed against the surface of the plate, the first motor 802 is controlled to work, and the output shaft of the first motor 802 is started to rotate to drive the incomplete gear 804 to rotate, so that the incomplete gear 804 can drive the rack 801 to move, so that the rack 801 can drive the support arm 910 to move, so that the support arm 901 can drive the straight plate 905 to move synchronously, and the straight plate 905 can drive the roller 904 to move (the material of the roller 904 is rubber, which increases the friction between the plate and the roller 904). When the roller 904 moves, it can drive the ratchet 906 to move synchronously. Under the action of the pawl 907, the ratchet 906 cannot rotate, so that the roller 904 can push the plate to move on the surface of the rotating rod 12. When the incomplete gear 804 is no longer engaged with the rack 801, the plate is stopped from being pushed, so that the plate can move a certain distance. According to the above operation, the plate is fixed again, and the output shaft of the second motor 10 is started to rotate in the opposite direction, so that the plate moves in the opposite direction for cutting. By replacing the incomplete gear 804 with a different number of teeth, the movement distance of the rack 801 can be adjusted, so that the feeding distance of the plate can be adjusted. The output shaft of the first motor 802 is controlled to rotate in the opposite direction so that the roller 904 can rotate on the surface of the plate. At this time, the pawl 907 is no longer engaged with the ratchet 906, so that the roller 904 will not drive the plate to move when it is reset.

[0055] Replacement process of incomplete gear 804:

[0056] The operator rotates and removes the two bolts on the surface of the mounting bracket 803, so that the mounting bracket 803 and the first motor 802 can be removed, and at the same time removes the incomplete gear 804 from the output shaft surface of the first motor 802 for replacement.

[0057] Although the invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
