Hole making device

Abstract

The invention belongs to the technical field of drilling, and particularly discloses a drilling device which comprises a reference frame, a positioning assembly and a measuring unit and is used for positioning a sheet-shaped or plate-shaped to-be-drilled piece, the reference frame comprises a first positioning part and a second positioning part, and the first positioning part and the second positioning part abut against the two adjacent side edges of the to-be-drilled piece correspondingly. The first positioning part is arranged along the X direction; a datum hole is formed in the positioning assembly in the Z direction in a penetrating mode, the axis direction of the datum hole is perpendicular to the machining surface of the part to be drilled, and the positioning assembly is slidably connected with the datum frame so as to adjust the projection position of the datum hole on the machining surface; the measuring unit is used for detecting the distance between the center of the reference hole and the first positioning part in the Y direction and the distance between the center of the reference hole and the second positioning part in the X direction. Manual marking and hole alignment in advance are not needed, the measurement operation of hole site center positioning is simplified, the hole site measurement positioning and machining precision is improved, and batch machining and production of to-be-drilled parts are facilitated.

Description

technical field [0001] The invention relates to the technical field of hole making, in particular to a hole making device. Background technique [0002] At present, the hole-making technology is mainly divided into three types. One is the method of direct drilling, which is likely to cause serious delamination around the hole, large and many burrs, and cracks at the bottom of the hole; the other is to use The method of punching, the hole diameter that can be processed by this method is limited, the quality of the processed hole is not high, and the cost of parts produced in small batches is relatively high; the last one is the method of interlayer, which uses hard The solid metal material is clamped, and then the hole is made. [0003] At present, workpieces such as gaskets or laminates usually adopt the method of interlayer drilling. The hole making process is: operation preparation, marking according to the drawing, foreign punching positioning, drilling, review, grinding...

Problems solved by technology

[0002]At present, the hole-making technology is mainly divided into three types. One is the method of direct drilling, which is likely to cause serious delamination around the hole, large and many burrs , cracks will also appear at the bottom of the hole; the other is the punching method, which has a limited hole diameter, low quality holes, and high cost for parts produced in small batches; the last one It adopts the interlayer method, clamps the upper and lower parts of the workpiece to be processed with hard metal materials, and then makes holes

[0003] At present, workpieces such as gaskets or laminates usually adopt the method of interlayer drilling. Positioning, drilling, review, grinding, and component identification, before making holes on the parts to be made, it is necessary to use special tools to manually mark the center of the hole position, then fix the parts to be made with fixtures, and then adjust the drill bit to align with the marking. It is not only cumbersome to operate, it is easy to cause the secondary positioning error of the center of the hole, and the coordinates of the hole to be made need to be measured and positioned by the X coordinate and the Y coordinate respectively, which reduces the production efficiency of the hole to be made , which seriously affects the batch processing and production of the parts to be holed
