High-precision vertical boring machine and machining method

By designing a boring bar guard, a jacket, and a flip-over fluid drainage mechanism, the problem of fluid spraying not being possible in the dead corner at the top of cylindrical workpieces during boring machine processing was solved. This enabled high-precision machining and automated cutting fluid control on the boring machine, avoiding errors and damage, and improving machining efficiency and product quality.

AI Technical Summary

Technical Problem

When machining cylindrical workpieces, existing boring machines cannot reach the cutting fluid in the dead corner of the top groove, resulting in a decrease in workpiece quality. Furthermore, angular errors are prone to occur when cutting grooved threads, leading to workpiece scrap.

Method used

It employs a boring bar guard, a boring bar collet, and a flipping and draining mechanism. Through the cooperation of a drive shaft, a bevel plate, a coupling, and a hydraulic cylinder, it realizes the lateral movement of the boring bar and the action of spraying fluid. Combined with the flipping of the ball sleeve, the drain pipe, and the push rod, it automatically controls the spraying and stopping of cutting fluid, avoiding errors and damage.

Benefits of technology

It improves the practicality and convenience of boring machines, avoids grooving errors and damage to boring bar, and realizes high-precision machining of workpieces and automated cutting fluid control.

Abstract

The invention relates to the technical field of vertical boring mills, in particular to a high-precision vertical boring mill and a machining method.The high-precision vertical boring mill comprises a boring cutter protective cover, a boring cutter clamping sleeve and an overturning liquid drainage mechanism, a main shaft capable of rotating in a lifting mode is arranged in the boring cutter clamping sleeve, a driving shaft is fixedly installed at the bottom end of the main shaft, and a bevel edge plate is fixedly installed at the bottom end of the driving shaft; a driving shaft, a bevel edge plate and a coupling shaft are arranged on the inner wall of the limiting sleeve, and two driving grooves are formed in the outer wall of the coupling shaft. Through cooperation of the driving shaft, the beveled edge plate, the coupling shaft, the limiting groove and the hydraulic cylinder, in order to avoid subsequent continuous errors or damage to a boring cutter rod when grooving operation is carried out and grooving is abnormal or wrong, an operator can start the hydraulic cylinder and the beveled edge plate to move up and down in the driving groove and drive the coupling shaft to move transversely, so that the boring cutter rod is prevented from being damaged; and meanwhile, the boring cutter rod synchronously and transversely enables the blade to be separated from the slotting position, operation is easy, and practicability of the device is improved.
