Abstract

The utility model relates to a special outlet crank cutter bar of a boring and milling machine, which aims to solve the problems of low machining accuracy of a large-diameter crank of the present cutter bar and poor stability of the cutter bar and a cutting tool. The utility model is characterized in that a cutter bar is provided with steps and platforms, a front end axial line of the cutter bar (1) is provided with an opening (2), a screw hole (4) in which a top thread (5) is arranged on the cutter bar (1) above the opening (2), and a hole (3) is arranged on the axial line of the middle part of the cutter bar (1). The special outlet crank cutter bar of a boring and milling machine can process the large-diameter crank, at the same time, the stability of the cutter bar and the cutting tool is enhanced, and the machining quality of workpieces is raised.

Description

The boring and milling machine special use bores a mouthful crank knife bar

Technical field:

The utility model relates to the used a kind of instrument of field, oil field processing oil pumper parts, belongs to a kind of boring and milling machine special use and bores a mouthful crank knife bar.

Background technology:

Knife bar is installed in and processes crank on the boring spindle, utilize boring spindle and knife bar to be connected, with the tip iron boring spindle and knife bar tightly are buckled together again, carry out boring processing, in the prior art, knife bar is carefully in processing crank process, the excessive hole precision of crank diameter does not reach requirement, process the requirement that does not all reach the drawing precision at the processing and utilization facing head, knife bar poor stability in addition, quality to workpiece is also influential, also has cutter stability also poor, and is also influential to the quality of workpiece.

Summary of the invention:

In order to solve the deficiency that exists in the background technology, the utility model provides a kind of boring and milling machine special use to bore a mouthful crank knife bar, this boring and milling machine special use bores a mouthful crank knife bar can process large diameter crank, and knife bar and cutter stability strengthens simultaneously, has improved the crudy of workpiece.

Technical solution adopted in the utility model is: this boring and milling machine special use bores a mouthful crank knife bar and comprises knife bar, knife bar has stage, on the knife bar front end axis opening is arranged, and has a hole on the knife bar of opening top, the silk hole is built-in with jackscrew, has the hole on the axis of knife bar middle part.

Above-mentioned hole is a bar hole.

The beneficial effects of the utility model are: adopt technique scheme, this boring and milling machine special use bores a mouthful crank knife bar and has stage, can reach the requirement of drawing precision for large diameter crank processing, satisfied client's demand, knife bar and cutter stability strengthens simultaneously, has improved the crudy of workpiece.This knife bar also is applicable to the processing blind hole workpiece, and the tip face of this knife bar is a metric system 80, has passed through the Quenching Treatment smooth surface.
