Description

Technical Field

[0001] The present application relates to the field of hole punching machines, and in particular to an automatic hole punching device. Background Art

[0002] A punching device 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.

[0003] During the production process of workpieces, when drilling holes on workpieces, a single drill bit is generally used for drilling, and each drilling machine is equipped with an operator. The operator feeds the material to the drilling machine, clamps and positions it, and then starts the drilling machine to drill holes in the workpiece. Then the worker adjusts the clamping again and moves the workpiece to the next drilling location for drilling. After drilling a hole in the workpiece, the worker needs to repeatedly adjust and move the workpiece position, which makes the drilling operation inefficient and the work intensity high. There are also safety hazards when the worker repeatedly moves the workpiece position. Utility Model Content

[0014] By adopting the above technical solution, the hydraulic cylinder can be controlled so that the hydraulic cylinder drives the pressing plate to press the workpiece onto the processing plate, thereby quickly fixing the workpiece onto the processing plate.

[0015] Optionally, a plurality of pressing blocks are fixedly connected to the lower end of the extrusion plate.

[0016] By adopting the above technical solution, the pressing block can abut against the workpiece, thereby achieving a protective effect on the pressing plate.

[0017] Optionally, the pressing block is made of rubber material.

[0018] By adopting the above technical solution, the rubber pressure plate can protect the workpiece and reduce the wear of the workpiece by the pressure block.

[0033] A fixing hole 21 is provided on the upper end surface of the processing plate 2. The fixing hole 21 is set in a rectangular shape. An abutment plate 22 is fixedly connected to the upper end of the processing plate 2. The abutment plate 22 is set along the length direction of the processing plate 2. A slide plate 9 is provided in the fixing hole 21. The slide plate 9 is set in a rectangular parallelepiped shape and the end of the slide plate 9 abuts against the inner wall of the fixing hole 21. The processing plate 2 is provided with an adjustment component 4 for adjusting the position of the slide plate 9 in the fixing hole 21.

[0034] The adjustment assembly 4 includes two adjustment screws 41 , the axes of the two adjustment screws 41 are parallel to each other, the adjustment screws 41 are threadedly connected to the processing plate 2 , and the rods of the adjustment screws 41 pass through the processing plate 2 and the fixing holes 21 , and are finally rotatably connected to the slide plate 9 .

[0035] Thus, the two adjusting screws 41 are rotated simultaneously, and the adjusting screws 41 can drive the slide plate 9 to slide in the fixing hole 21 .

[0036] A plurality of limiting grooves 91 are provided on the upper end surface of the slide plate 9, and the limiting grooves 91 are arranged equidistantly along the length direction of the slide plate 9. A driving member 6 is fixedly connected in each limiting groove 91. In this embodiment, the driving member 6 is arranged as a driving motor.
