[0002] The drill bit guide sleeve device of the precision drilling machine in the prior art is arranged on one side of the machine head. If the drill bit is guided by this unilateral guiding mode, it has the following disadvantages: 1. The drill bit guide sleeve device is used to guide the drill bit. When guiding, the vibration of the drill bit will be transmitted to the drill bit guide bushing device. Since the drill bit guide bushing device is unilaterally slid and fixedly installed on one side of the machine head, its anti

Abstract

The invention provides a drill bit guide sleeve device of a precise drilling machine. The device comprises a machine head, a machine head mounting base, a motor, a cutter beating device, a guide sleeve and a guide sleeve lifting driving device; the guide sleeve lifting driving device comprises a connecting piece, a first lifting module and a second lifting module; the first lifting module is arranged on the left side of the machine head; the second lifting module is arranged on the right side of the machine head; a mounting hole for mounting the guide sleeve is formed in middle of the connecting piece; the guide sleeve is mounted in the mounting hole; the guide sleeve comprises a gland, a first guide sleeve, a transition sleeve and a second guide sleeve; the second guide sleeve is mountedat the bottom of the first guide sleeve after sleeving the transition sleeve; and after the gland sleeves the lower part of the second guide sleeve, the second guide sleeve is mounted at the bottom ofthe first guide sleeve. Through use of two-edge stressing, the device achieves better vibration resistance, greatly improves the drill bit stability, is suitable for two different chip drilling modes, greatly reduces the replacement time of the guide sleeve of the precise drilling machine, and reduces the cost.

Description

technical field [0001] The invention relates to the field of precision drilling machines, in particular to a drill bit guide sleeve device of the precision drilling machine. Background technique [0002] The drill bit guide sleeve device of the precision drilling machine in the prior art is arranged on one side of the machine head. If the drill bit is guided by this unilateral guiding mode, it has the following disadvantages: 1. The drill bit guide sleeve device is used to guide the drill bit. When guiding, the vibration of the drill bit will be transmitted to the drill bit guide bushing device. Since the drill bit guide bushing device is unilaterally slid and fixedly installed on one side of the machine head, its anti-vibration ability is low, and the drill bit cannot be stably guided, which will lower the drill bit. 2. When the drill guide device is moving up and down, it is easy to shake, which will also affect the processing accuracy; 3. Since the drill guide sleeve devi...
