Abstract

The invention discloses a hole boring device. A conehead rod is arranged at the inner end inside a middle blind hole positioned at the tail of a knife bar, the front end of the conehead rod is of a cone-shaped structure, supporting pillars are symmetrically installed on the waist of the knife bar, the inner end of every supporting pillar is of an inclined-plane-shaped structure, the inclined plane of every supporting pillar is contacted with the conical surface of the conehead rod, the central axis of every supporting pillar is perpendicular to the central axis of the knife bar, steel balls are fixed at the upper ends and the lower ends of the supporting pillars respectively through flange caps, a top thread is installed on an opening part of the middle blind hole of the knife bar, and a plurality of bolts are arranged at the head of the knife bar and tighten and loosen a knife holder. The hole boring device is not subjected to the influence of eccentric acting force easily in cutting, the knife bar does not vibrate easily, workpiece quality is good, and knife collapse can be reduced simultaneously.

Description

A kind of boring device

Technical field

The present invention relates to a kind of machinery processing apparatus, be specifically related to a kind of boring device, belong to manufacturing technology equipment technology field.

Background technology

In machinery manufacturing technology field, the hole that the precision that diameter is larger is higher generally adopts boring device and corresponding technique to manufacture, existing boring device generally is mounted in a boring bar on boring machine and is arranged on that the boring cutter of boring bar end forms, although existing this boring device has advantages of simple in structure, but, due to boring bar at work in vacant state, the impact of the wobbler action power that cutter head produces when cutting in addition, knife bar is easily vibration not only, cause the Quality Down of workpiece, with sometimes also collapsing the cutter phenomenon.

Summary of the invention

The object of the invention is to: for the existing above-mentioned defect of existing boring device, the invention provides a kind of novel boring device, overcome the existing existing above-mentioned defect of boring device.

The present invention realizes that the technical scheme that above-mentioned purpose adopts is: this kind of boring device comprises knife bar, the conehead bar, spring, jackscrew, support column, flanged cap, steel ball, tool rest, cutter head, bolt, regulate screw mandrel, spring leaf, hold inside and be provided with the conehead bar in the middle blind hole of knife bar afterbody, the front end of described conehead bar is conical structure, at the knife bar waist, section is equipped with support column symmetrically, the inner end of the described support column structure that takes the form of inclined plane, and the inclined-plane of support column contacts with conehead bar conical surface, the central axis of support column is mutually vertical with the central axis of knife bar, the two ends up and down of support column are fixed with a steel ball by flanged cap respectively, install and fix a spring leaf respectively on the knife bar of support column one side, the cylindrical position phase clamping of one end of described spring leaf and support column, in the middle of knife bar, the oral area of blind hole is equipped with jackscrew, in hole between jackscrew and conehead bar, spring is housed, head movement at knife bar is equipped with tool rest, , head at knife bar is provided with a plurality of bolts, tool rest is loosened in described bolt tightening, head at tool rest is equipped with cutter head, on the knife bar at the back side of tool rest, the adjusting screw mandrel is installed, the head of described adjusting screw with between tool rest, in the mode of threaded engagement, install together with.

Beneficial effect: when the present invention works, by regulating the stroke of support column, knife bar is supported in the hole processed by support column and steel ball, thereby plays the effect of guiding and balanced cutting power, simultaneously, due to the stroke that has reduced knife bar, also increased the intensity of knife bar, so, do not allow to be subject to the impact of wobbler action power when cutting, knife bar is not easy vibration, and the quality of workpiece is better, with sometimes also reducing and collapse the cutter phenomenon.
