[0022] The base 1 is made of aluminum alloy, and the electronic button 3 is connected to the battery 4 by electrical connection;
[0023] In this embodiment, reference Figure 2 and Figure 3 The clamping mechanism 2 includes a clamping plate 201 slidably connected to both sides of the top center of the base 1, a piston plate 202 is slidably connected inside the clamping plate 201, a reset spring 203 is fixedly connected to the outer wall of the piston plate 202 and inside the clamping plate 201, a push rod 204 is fixedly connected to the outer wall of the piston plate 202 and on the side away from the reset spring 203, an anti-slip pad 205 is fixedly connected to the outer wall of the push rod 204 and at one end away from the piston plate 202, a guide tube 206 is fixedly connected to the inside of the clamping plate 201 and at a position close to the piston plate 202, a micro air pump 207 is fixedly connected to the outer wall of the guide tube 206 and at one end away from the piston plate 202, a slider 208 is fixedly connected to the bottom of the base 1, a sliding nut 209 is fixedly connected to the inside of the slider 208, a driving screw 210 is threadedly connected to the inside of the sliding nut 209, and hand wheels 211 are fixedly connected to both ends of the driving screw 210 and on both sides of the base 1;
[0024] The clamping plate 201, the slider 208 and the push rod 204 are all made of stainless steel, the piston plate 202, the reset spring 203, the push rod 204 and the anti-skid pad 205 are all provided in multiple groups, the reset spring 203 and the clamping plate 201 are connected in a fixed manner, the anti-skid pad 205 is made of a rubber pad, the push rod 204 and the clamping plate 201, the slider 208 and the base 1 are connected in a sliding manner, the slider 208 is an H-shaped structure design, the driving screw 210 passes through and extends to the outside of the base 1, the driving screw 210 and the base 1 are connected in a rotating manner, the driving screw 210 is made of two screws with opposite thread directions, and the micro air pump 207 is connected to the electronic button 3 by electrical connection.
[0025] The working process of the utility model is as follows: when the positioning fixture of the machining center designed by the present invention is in operation, a plate is placed on the top of the base 1, and the hand wheel 211 is turned. The hand wheel 211 drives the driving screw 210 to rotate. The rotating driving screw 210 drives the slider 208 and the clamping plate 201 to move inward through the sliding nut 209. The clamping plate 201 moving inward clamps the plate. The electronic button 3 is pressed. The electronic button 3 starts the micro air pump 207. The micro air pump 207 sends air into the clamping plate 201 through the guide tube 206. The air pushes the piston plate 202 and the push rod 204 to move outward. The outward moving push rod 204 will press against different positions of the plate, thereby clamping the plate on the base 1, and the base 1 and the plate are sent to the processing equipment for processing. After the processing is completed, the hand wheel 211 is rotated in the opposite direction, and the hand wheel 211 drives the driving screw 210 to rotate in the opposite direction. The driving screw 210 rotating in the opposite direction will drive the slider 208 and the clamping plate 201 to move outward through the sliding nut 209. The clamping plate 201 moving outward no longer clamps the plate. At the same time, the micro air pump 207 draws out the air, and the return spring 203 pulls the piston plate 202 and the push rod 204 to move inward, and the push rod 204 returns to the clamping plate 201.
[0026] 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.
