head-changing drilling machine

Abstract

The invention discloses a drilling machine capable of replacing drilling heads. A base of the drilling machine is connected with a main shaft box via a machine pillar; a cavity is formed in an operation box which is adhered to the lower part of the main shaft box; an active rotation shaft is arranged in the cavity; an active rotation gear in transmission connection with the active rotation shaft is arranged on the active rotation shaft; the active rotation gear is engaged with a transmission rotation gear; a transmission rotation shaft is in transmission connection with the transmission rotation gear; a rotation disc is arranged on the transmission rotation shaft; a plurality of evenly-distributed driving telescopic shafts are arranged on the rotation disc; each driving telescopic shaft comprises an inner rod and an outer rod; each inner rod is connected with the rotation disc; a drilling head clamp used for mounting a drilling head is arranged on each outer rod; fixed through grooves are formed in the operation box; the drilling head clamps pass through the fixed through grooves. According to the drilling machine capable of replacing the drilling heads, when the active rotation shaft rotates, the active rotation gear is driven to rotate; the transmission rotation gear engaged with the active rotation gear also rotates; the transmission rotation gear drives the rotation disc connected with the transmission rotation shaft; after the rotation disc rotates, the drilling heads are automatically replaced; the operation steps are reduced.

Description

technical field [0001] The invention relates to the field of a head-changing drilling machine, in particular to a head-changing drilling machine. Background technique [0002] Drilling machines are widely used in modern industry and are common mechanical processing equipment. They are mostly used in drilling and tapping processes. They are divided into two types: ordinary drilling machines and CNC drilling machines. In modern mechanical processing, it is often required to continuously complete two or more processes in the drilling, reaming, countersinking, reaming and tapping of the workpiece to improve the accuracy of the shape, size and position of the workpiece hole. At the same time, the times of loading, unloading and positioning are reduced, and the production efficiency is improved. [0003] Although the single-bit drilling machine of the ordinary drilling machine is easy to operate, it needs to manually replace the drill bit for drilling. During the operation, there...

Problems solved by technology

[0003] Although the single-bit drilling machine of the ordinary drilling machine is easy to operate, it needs to manually replace the drill bit for drilling. During the operation, there will inevitably be disadvantages such as difficult positioning, low processing accuracy and low efficiency; when the existing drilling machine is processed, the workpiece is fixed, and the spindle Rotate in the sleeve and feed axially with the sleeve. Since the spindle of the vertical drilling machine cannot move in a plane perpendicular to its axis, the workpiece must be moved to make the drill bit coincide with the center of the workpiece hole when drilling.

At present, the existing drilling machine requires human to move the workpiece. The positioning accuracy of the hole system is not high, and the process is relatively complicated. It is not convenient and fast enough for mass production, and the labor intensity is also high, which reduces the work efficiency.
