Semi-automatic proofing punching and marking-out instrument, punching machine and using method

Abstract

The invention discloses a semi-automatic proofing punching and marking-out instrument, a punching machine and a using method. The instrument comprises a sleeve, an elastic piece, a pull handle, a limiting piece, a top cap and a punching piece. The elastic piece is arranged in the sleeve in a sleeved mode; a through hole is formed in the top cap; one end of the punching piece is connected with the elastic piece, and the other end of the punching piece is arranged in the through hole of the top cap in a sleeved mode; the pull handle is connected on the punching piece; the two ends of the limiting piece are connected with the sleeve and the top cap correspondingly; the limiting piece is provided with a through groove used for sliding of the punching piece and the pull handle in the axial direction; and the limiting piece is provided with an annular groove for clamping and holding the pull handle in the radial direction. The structure is simple, usage is convenient, and the instrument can be mounted on a numerically-controlled machine tool. By means of a spring type proofing dotting-punch instrument, punching and dotting-punch can be realized through manual operation under the condition that a hole site program is written in advance, and meanwhile, the instrument can further be used for blank surface marking out, the safety is high, and the operability is strong.

Description

technical field [0001] The present invention relates to a kind of equipment used for the drilling position of center drilling point, in particular to a semi-automatic proofing, punching and scribing tool, punching machine and using method. Background technique [0002] Before the holes can be machined by the CNC machine, the drill bits need to be drilled through the center drill point. When spot drilling a large workpiece with a group of holes distributed on the blank, it is difficult to determine the safety distance and spot drilling depth when writing the drilling cycle numerical control program because the surface of the blank is uneven and the surface is not perpendicular to the machine tool spindle. If the spot drilling depth value is set larger, the spot drilling depth may be too deep. When the hole position is wrong, the deeper spot drilling will not be covered, resulting in workpiece defects or even scrapping; if the spot drilling depth value is set smaller, Then th...

Problems solved by technology

When spot drilling a large workpiece with a group of holes distributed on the blank, because the surface of the blank is uneven and the surface is not perpendicular to the spindle of the machine tool, it is difficult to determine the safety distance and spot drilling depth when programming the drilling cycle CNC program

If the spot drilling depth value is set larger, the spot drilling depth may be too deep. When the hole position is wrong, the deeper spot drilling holes will not be covered and cause workpiece defects or even be scrapped; if the spot drilling depth value is set smaller, It is possible that the center drill cannot touch the workpiece and the center hole cannot be formed

In addition, for some workpieces, it is necessary to mark the line on the machine tool, but because the surface of the blank is uneven, if the line is marked with an ordinary thimble, the lines on the surface of the blank will be of different depths, and at the same time, the wear of the thimble will be aggravated
