A high-precision drilling machine for workpiece machining

Abstract

The invention discloses a high-precision drilling machine for workpiece processing, comprising a bottom plate, a driving part is fixedly connected to the rear of the upper end of the bottom plate, and a cooling device and two drilling devices respectively penetrate through the front part of the driving part. The upper end of the bottom plate is fixedly installed with the actuator, the middle of the upper end of the bottom plate is provided with a No. 2 chute, the left part of the upper end of the bottom plate is fixedly installed with a No. 1 cylinder, the output end of the No. 1 cylinder is fixedly installed with a No. The right end of the push rod is fixedly connected with a mounting piece, two processing tables are fixedly installed in the middle of the mounting piece, and a numerical control table is fixedly mounted at the rear of the upper end of the bottom plate. The high-precision drilling machine for workpiece processing of the present invention can realize drilling processing of different depths, and the drilling depth is accurate; and the workpiece can be processed with different apertures and different models, thereby improving the applicable range of the drilling machine; and The cooling device can avoid the high temperature operation of the drill bit; in addition, the drilling machine is fixed by the action of negative pressure, and the fixing operation is more convenient.

Description

technical field [0001] The invention relates to the technical field of drilling machines, in particular to a high-precision drilling machine used for machining workpieces. Background technique [0002] A bed refers to a machine tool that mainly uses a drill to machine holes in a workpiece. Usually the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. However, the existing drilling machines often have the following problems in the process of use: 1. The processing accuracy of the existing drilling machines is not high, and the depth of the drilling is generally estimated according to the external length of the drill bit, so the drilling depth cannot be accurate, and the error is large; 2. The existing drilling The processing efficiency of the drilling machine is not high, and it is inconvenient to process the workpieces with different apertures and models, resulting in a narrow application range of the drilling mach...

AI Technical Summary

Problems solved by technology

However, the following problems often exist in the existing drilling machine during use; 1. The processing accuracy of the existing drilling machine is not high, and the depth of the drilling is generally estimated according to the external length of the drill bit visually. The drilling depth cannot be accurate and the error is large; 2. The existing The processing efficiency of the drilling machine is not high, and it is inconvenient to process workpieces with different apertures and different models, resulting in a narrow application range of the drilling machine, which is not conducive to large-scale promotion and use; 3. The drill bits of the existing drilling machine are very easy to operate at high temperature during the long-term processing process , resulting in a short service life of the drilling machine and increased equipment costs; 4, when the existing drilling machine processes the workpiece, it often uses clamping parts to fix the workpiece, which not only easily damages the workpiece during the clamping process but also The clamping work is cumbersome, which makes the drilling machine inconvenient to use
