Description

Technical Field

[0001] The utility model relates to the technical field of plate punching tooling, in particular to a plate punching, clamping and fixing tooling. Background Art

[0002] A drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. It is also called a drilling machine, a punching machine, a hole-drilling machine, a through-hole machine, etc. It achieves the desired effect by drilling holes in precision parts. There are semi-automatic drilling machines and fully automatic drilling machines. With the increase in human resource costs, most companies are considering fully automatic drilling machines as their development direction.

[0003] The existing plate fixing tooling generally uses claws at the four corners to limit the plate. The plate is easy to collide with the claws during transportation and placement, causing damage to the appearance. When fixing the claws, it can only be done manually one by one. Not only is the operation complicated, but it is also easy to cause the plate to tilt during the clamping process, resulting in the deviation of the drilling position. To this end, we provide a plate punching clamping and fixing tooling to solve the above problems. Utility Model Content
