High-precision deep hole processing machine

Abstract

The invention discloses a high-precision deep hole processing machine, which comprises a workbench, a power mechanism and a gun drill, wherein the power mechanism is connected with a main shaft, the main shaft is connected with the gun drill, and the main shaft and the gun drill are provided with a shaft cavity and a drill cavity which are mutually communicated respectively; the main shaft is connected with a high-pressure water inlet pipe communicated with the shaft cavity; a metal ring, a sealing ring and a high-speed radial bearing are sleeved on the main shaft positioned on at least one side of the high-pressure water inlet pipe; and the workbench is provided with an outer cooling pipe, and the workbench is erected on a guide rail and is in transmission connection with the power device. The high-precision deep hole processing machine has high drilling speed, high efficiency and high drilling depth, well protects workpieces, and does not need to retract a cutter midway; the drilling depth can reach 100 times diameter of a drill bit; and the processing machine has small floor area and low cost, is easy to maintain, and can be used for automatic batch processing.

Description

technical field [0001] The invention relates to a drilling device, in particular to a high-precision deep hole processing machine. Background technique [0002] The existing drilling methods are mostly divided into manual and semi-automatic. The manual drilling method is to hold a gun drill equipped with a drill bit and drill the workpiece to be drilled. However, during manual operation, due to the high-speed operation of the drill gun , It takes a lot of effort to grasp the drill gun. This method cannot achieve accurate positioning during drilling. During the drilling process, because the drill bit rotates at a high speed, the contact with the workpiece will generate high heat, which is easy to burn the workpiece or damage the drill bit. The semi-automatic drilling method is realized by a drilling machine. The drilling machine can be accurately positioned during use, but its drill bit will also generate high heat. The general solution is to put a basin of water next to the ...

[0002] The existing drilling methods are mostly divided into manual and semi-automatic. The manual drilling method is to hold a gun drill equipped with a drill bit to drill the workpiece to be drilled. However, during manual operation, due to the high-speed operation of the drill gun , It requires a lot of effort to grasp the drill gun. This method cannot achieve accurate positioning during drilling. During the drilling process, because the drill bit rotates at a high speed, the contact with the workpiece will generate high heat, which is easy to burn the workpiece or damage the drill bit.

The semi-automatic drilling method is realized by a drilling machine. The drilling machine can be accurately positioned during use, but its drill bit will also generate high heat. The general solution is to put a basin of water next to the workpiece and pour some after drilling for a while. The water is on the drilling position of the workpiece to cool it down, and the hands must leave the workpiece or the operating rod when pouring water, which is extremely inconvenient to operate, slow in speed and low in efficiency
