Further, a countersunk hole is opened on the fixed clamping bar, which is fixedly installed on the base by a countersunk screw, and a slotted hole is opened on the movable clamping bar.

Further, five holes are opened on the front end of the spring seat block.

Further, a through hole is opened at both ends of the movable clamping block, and a groove is opened on the bottom surface of the movable clamping block.

Further, the spring is installed in the three holes in the middle of the spring seat block, and the guide rod of the movable clamping block is installed in the two holes at both ends of the spring seat block.

Further, two slot holes are opened on the upper surface of the front positioning plate, and a triangular notch is opened in the middle of the front and rear end surfaces respectively. Further, four pin holes are opened on the support rod.

Further, a notch is formed at the front end of the handle.

Further, the end of the shifting block is a cam structure.

The positioning and clamping device used in the PCB numerical control drilling machine described in the utility model drives the clamping and loosening actions in the horizontal and vertical directions through a cylinder, thereby reducing parts and simplifying the structure. The clamping device adopts a spring to maintain the clamping force, so that the clamping mechanism can still maintain the clamping state when the air source is lost, ensuring the reliability of the clamping device, and the clamping mechanism has strong integrity and is easy to install.

detailed description

As shown in Figure 1-5, a PCB CNC drilling machine material clamping and positioning device includes a base 10, a movable clamping bar 8 and a fixed clamping bar 9 are installed in the middle of the upper end surface of the base, and the front ends of the two clamping bars A spring seat block 7, a movable clamping block 6, and a front-end positioning block 5 are installed in sequence. Three springs 11 and two clamping block guide rods 12 are installed on the spring seat block. The cylinder 3 is installed on the lower end surface of the base. Installed at both ends of the cylinder, the strut 1 is connected with four handles 2, and the four shifting blocks 4 are installed on the base and connected with the four handles 2 respectively.

Further, the fixed clamping bar 9 is provided with a countersunk hole, which is fixedly mounted on the base 10 by a countersunk screw, and the movable clamping bar 8 is provided with a slotted hole.

Further, five holes are opened on the front end of the spring seat block 7 .

Further, a through hole is opened at both ends of the movable clamping block 6 , and a groove is opened on the bottom surface thereof.

Further, the spring 11 is installed in the three holes in the middle of the spring seat block 7 , and the clamping block guide rod 12 is installed in the two holes at both ends of the spring seat block 7 .

Further, two slot holes are opened on the front of the front-end positioning block 5, and a triangular notch is opened in the middle of the front and rear ends. Further, four pin holes are opened on the strut 1 .

Further, the front end of the handle 2 is provided with a notch.
