Description

Technical Field

[0001] The utility model relates to the technical field of punching processing equipment, in particular to a spacing-adjustable punching device. Background Art

[0002] Punching machine is one of the processing machines frequently used in the process of mechanical parts processing. Punching machine refers to the general term for machines and equipment that use a tool that is harder and sharper than the target object to leave cylindrical holes or holes on the target object through rotary cutting or rotary extrusion. It is also called a drilling machine, a drilling machine, a punching machine, a through-hole machine, etc. The desired effect is achieved by punching holes in precision parts. However, the existing punching machines all complete the punching operation by manually moving the plate to be punched. When operating this type of punching machine, it is easy to cause biased holes, burst holes and uneven hole sizes due to improper manual operation, which affects the quality of the product and the accuracy is not high.

[0003] The existing public technology disclosed in the publication number CN216325244U discloses an automatic plate punching machine, including a base and a frame arranged on the base, a cylinder is installed on the top of the frame, the piston rod of the cylinder passes through the top of the frame and is connected to a motor box at its end, a first motor is installed in the motor box, the output shaft of the first motor passes through the bottom plate of the motor box and a drill bit is fixed at its end, two guide rails are arranged in parallel on the base, and the drill bit is located on the symmetric axis of the two guide rails; sliding plates are movably installed on the two guide rails, and a metal plate fixing platform is arranged on the upper end of the sliding plate; a connecting rod is fixed between the two sliding plates; and a driving assembly is also arranged on the base, and the driving assembly is connected to the connecting rod. The utility model has a simple structure and a reasonable design. It can automatically punch holes through PLC control, and the punched holes have high precision. Compared with manual punching, it has high efficiency and lower labor costs.

[0004] Although the above patent can save manpower, there are still some shortcomings in its use. First, the patent only uses a single drill bit to punch the plate, the processing efficiency is not high enough, and the spacing of the holes cannot be adjusted, which is not convenient to use. Secondly, although the patent uses a magnetic seat to fix the plate, the stability of the plate fixation is not high enough, which may affect the subsequent punching accuracy. In addition, the patent lacks a certain shielding structure when punching, and debris may splash during the punching process, which is more troublesome to clean. By targeting the problems in the relevant technology, no effective solution has been proposed so far. Utility Model Content
