High-precision drilling machine for workpiece machining

Abstract

The high-precision drilling machine comprises a bottom plate, a driving part is fixedly connected to the rear portion of the upper end of the bottom plate, a cooling device and two drilling devices penetrate through the front portion of the driving part, an executing part is fixedly installed at the upper end of the bottom plate, and a second sliding groove is formed in the middle of the upper end of the bottom plate; a first air cylinder is fixedly mounted on the left portion of the upper end of the bottom plate, a first push rod is fixedly mounted at the output end of the first air cylinder, a mounting part is fixedly connected to the right end of the first push rod, two machining tables are fixedly mounted in the middle of the mounting part, and a numerical control table is fixedly mounted on the rear portion of the upper end of the bottom plate. According to the high-precision drilling machine for workpiece machining, drilling machining of different depths can be achieved, and the drilling depth is accurate; different hole diameters and different types of workpieces can be machined, and the application range of the drilling machine is widened; the cooling device can avoid high-temperature operation of the drill bit; in addition, the drilling machine is fixed through the negative pressure effect, and 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 use process: 1. The existing drilling machines have low processing accuracy, 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 workpiece with different apertures and models, resulting in a narrow application range of the drilling machine, which is ...

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
