Abstract

The utility model discloses a compound cutter for flushing and chamfering a vehicle rod piece, which comprises a cutter bar, a front blade and a rear blade, wherein two blades are both diamond-shaped blades with clearance angles; the front blade is fixed at the left side of the front end of the cutter bar, the cutting edge of the front blade is extruded out of the left front end of the cutter bar, and an included angle between the cutting edge of the front blade and the front end surface of the cutter bar is 45-55 degrees; the rear blade is fixed at the left side of the cutter bar and is positioned behind the front blade; a distance between the left lower edge of the front blade and the right upper edge of the rear blade is at least 2mm; the cutter tip of the rear blade is positioned on the left edge line of the cutter bar; and the cutting edge of the rear blade is extruded out of the left edge of the cutter bar and forms an included angle of 45 degrees with the front end surface of the cutter bar. In the compound cutter for flushing and chamfering the vehicle rod piece, two working procedures of flushing end surfaces and chamfering are combined, so that one cutter saddle is omitted, operation space is enlarged, the piece can be conveniently assembled and disassembled, production efficiency is improved, and cutter cost is lowered. The compound cutter is suitable for simultaneously surfacing and chamfering metal pieces, and is especially suitable for flushing and chamfering the vehicle metal rod piece.

Description

Flush and the chamfering compound tool of vehicle rod member

Technical field

The utility model relates to a kind of machine tool of metal rod, specifically a kind of flush and chamfering compound tool of vehicle rod member.

Background technology

Vehicle rod member product (as the front and back stabiliser bar connecting rod assembly of automobile product) need carry out the bar portion neat end face in two ends, the preliminary treatment of chamfering then mostly before welding or assembling at present, general two welding or the mechanical clamped cutting tool of adopting of this preprocessing process back and forth cuts, process end face earlier, tool changing chamfering again, its specific embodiments is as follows:

Two knife rests are installed in the track both sides, install one on each knife rest cutter, add and promote to go up end carriage man-hour earlier forward, utilize the vertical end face cutter processing end face that is provided with of blade, withdrawing then, promote end carriage down, utilization is finished chamfer machining with the rose reamer that axis is 45 ° of angles again, takes out workpiece behind the withdrawing.As seen, in the whole operation process operating personnel's action various, the distance between two knife rests and the workpiece of taking conflict----mutually when between two knife rests during close together, the idle stroke of cutter is short, working (machining) efficiency height, but difficulty during workman's pickup; When distance between two knife rests is far away, more convenient during workman's pickup, but the idle stroke of cutter is long, and working (machining) efficiency is low.

China utility model patent ZL200520106980X discloses " a kind of compound lathe tool ", symmetry is installed two blades on a knife bar, each blade has a plurality of minutes function blades, once is installed to need not the purpose that tool changing can realize turning, car endoporus and inside and outside chamfering.But this lathe tool belongs to axial feed and should not be used for face work.

Summary of the invention

The technical problems to be solved in the utility model provides the flush of a kind of vehicle rod member and chamfering compound tool, and neat end face and chamfering two-step are merged, save a knife rest, increased working space, make things convenient for upper and lower pieces, enhance productivity, reduced the cost of charp tool.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:

A kind of flush and chamfering compound tool of vehicle rod member, the preceding blade and back blade that comprise the knife bar of radially feed and on knife bar, fix;

Blade is the diamond shaped insert that has relief angle before described, is fixed in the front end left side of knife bar, and its cutting edge protrudes in the left front end of place, place knife bar, and the angle of preceding blade cut sword and knife bar front end face is 45 °～55 °;

Described back blade is the diamond shaped insert that has relief angle, be fixed in the left side of knife bar and be positioned at before the rear of blade, the upper right edge of the edge, lower-left of preceding blade and back blade is at a distance of 2mm or more than the 2mm, back blade point of a knife place falls within on the left side edge line of knife bar, and the cutting edge of back blade protrudes in the left side edge of place place knife bar and is 45 ° of angles with the front end face of knife bar.

More than being basic structure of the present utility model, is in order to satisfy the designing requirement of cutter tool cutting edge angle to the qualification of the corner dimension of preceding blade and knife bar front end face; The upper right edge of the edge, lower-left of preceding blade and back blade can guarantee that at a distance of 2mm or more than the 2mm blade bears certain cutting force.Use of the present utility model is as follows: after work piece positioning is tight, start main axis rotation, knife rest drive compound tool moves forward then, and preceding blade is cutting workpiece at first, cutting output is finished after the distance of the about diameter of work of X-axis forward feed, finishes neat end face processing; Blade cut workpiece after the continuation feed is finished chamfer machining; An actuation cycle is finished in withdrawing, pickup.The utility model merges neat end face and chamfering two-step, saves a knife rest, has increased working space, makes things convenient for upper and lower pieces, enhances productivity, and has reduced the cost of charp tool.

As optimization of the present utility model, connect through screw is fastening between described knife bar and preceding blade, the back blade.

As further optimization of the present utility model, described screw is a flat head screw.

Above-mentioned connecting mode is simple, easy accessibility, and securing member is with low cost and volume is little, does not hinder feed and cutting.

Further feature of the present utility model also has:

Blade is the numerical control blade that has relief angle.

The numerical control blade is the old blade that Digit Control Machine Tool is displaced, and described cutting blade is not use blade in the digital control processing process.This technical scheme makes utilization of resources maximization, deeply excavates the recycle value of waste and old blade, realizes that cost reduces.

As fully visible, owing to adopted above-mentioned technical scheme, the compared with prior art obtained technological progress of the utility model is: neat end face and chamfering two-step are merged, save a knife rest, increased working space, make things convenient for upper and lower pieces, enhance productivity, reduced the cost of charp tool.The utility model is applicable to that the face work of metalwork and chamfering process are shared, is particularly useful for the flush and chamfering of automobile metal system rod member.

The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.
