[0041] The working principle of a loading and unloading device for machine tool processing provided by the utility model is as follows: the utility model provides a loading and unloading device for machine tool processing. When it is necessary to load the workpiece to be processed, the adjusting structure 2 can move the position of the clamping structure 3 in three directions: up and down, left and right, and front and back according to the specific position of the workpiece. When the clamping structure 3 needs to move downward, the third motor 9 can be started to drive the third gear 209 to rotate counterclockwise, and the lifting frame 211 is pushed downward to a suitable position and stopped by means of the tooth plate 212.

Since the auxiliary tube 206 and the second screw rod 205 are threadedly connected and the front and rear positions of the movable base 203 will not change, the second screw rod 205 will move the movable base 204 forward and backward. The limit plate 213 can limit the movable base 203 to avoid that when the movable base 204 moves forward or backward more, the upward force on the movable base 203 is borne entirely by the first screw rod 202, thereby improving the service life of the adjustment structure 2.

[0042] The utility model provides a loading and unloading device for machine tool processing. When the clamping structure 3 is sent to the top of the workpiece by the adjusting structure 2, the adjusting structure 2 presses the auxiliary plate 31 downward until the pressing pad 38 abuts against the workpiece, and then the cylinder 10 can be started to move the adjusting frame 34 upward. During this process, the extrusion rods 35 on both sides of the adjusting frame 34 will squeeze the rotating member 32, so that the two rotating members 32 move towards each other with the clamping plates 36 at the same time until the clamping pad 37 abuts against the workpiece, wherein the clamping pad 37 with the strip-shaped protrusion can increase the friction between the clamping plate 36 and the workpiece, making the clamping more stable. By setting the clamping structure 3, the workpiece to be processed can be quickly clamped with a very simple structure, and the adjusting structure 2 can be cooperated to perform loading and unloading operations on it.
