Abstract

The utility model belongs to the technical field of machining, and relates to a novel formation machining cutter for a numerical control lathe. At present, small sealing parts are machined on a numerical control lathe, the middle part of each part is thick, two ends of each part are thin, and at the same time, excircle diameters of the two ends of each part are provided with very complicated grooves, the requirements on tolerances of circular beads inside the grooves are very strict, and the total groove width that is machined by a conventional machining cutter ranges from 5 grooves to 10 grooves at present. The utility model aims to provide the novel formation machining cutter for the numerical control lathe. The novel formation machining cutter adopts the structure that a blade is inserted in the front end of a cutter arbor, and the blade and the front end of the cutter arbor are fixed through a clamping fastening piece, the width of the blade is highly finished to reach 1.17 mm, an angle R at the front end of a knife edge is 0.45 mm, and the angle R at the rear end of the knife edge is 0.38 mm. The novel formation machining cutter achieves the purposes as follows: outer grooves on front end surfaces of parts can be machined during one clamping process of the parts, and repeated clamping or repeated tool changing can be avoided. The novel formation machining cutter is suitable for machining outer grooves on the end surfaces of parts with thick middle parts, thin ends and complicated excircles at the ends.

Description

Numerical control car processing and forming cutter

Technical field

The utility model belongs to the Machining Technology field, relates to a kind of novel numerical control car processing and forming cutter.

Prior art

At present, on numerically controlled lathe, process the class part of obturaging for a short time, because this part thick middle, two ends are thin, the two ends outside diameter has very complicated groove simultaneously, the tolerance of groove the inside fillet is very strict, and existing at present machine adds cutter and processes total big five to ten roads of groove width. because having limited, part shape seeks other alternative cutter.

Online in State Intellectual Property Office, announced a kind of " multifunctional numerical control lathe tool " patent on March 31st, 2010, patent No. CN200920093892.9, content is that the multifunctional numerical control lathe tool is made up of cutter hub and blade, blade adopts screw to be fixed on the same cutter hub.The blade of this CNC turning tool constitutes by three at the most, and wherein two blades are fixed in the front portion of cutter hub, and a blade is fixed in the middle part of cutter hub.Can adopt three blades to carry out digital control processing simultaneously according to the needs of processing work: i.e. the textural association mode of two blades of head and the blade in middle part; Also can adopt two blades to carry out digital control processing: to be the compound mode of two blades of head or the textural association mode of employing head and the blade in middle part.The multifunctional numerical control lathe tool has multifunctional performance, but its not only processing excircles but also can process endoporus can be finished semifinishing, fine finishining, can finish microstoning again, also can be used for the roughing of numerical control simultaneously.But still there is certain difficulty for processing the class part of obturaging for a short time.

Summary of the invention

The purpose of this utility model provides a kind of novel numerical control car processing and forming cutter.For addressing the above problem, the utility model is taked correct grinding typing blade width, realizes processing the class part of obturaging is for a short time finished groove outside the part front end face in a clamping processing, improves working (machining) efficiency.

The technical scheme that the utility model adopted is:

Numerical control car processing and forming cutter inserts blade by the knife bar front end, and forms with the clamping securing member is fixing, and it is characterized in that: blade width is 1.17 millimeters, and blade nose angle radius R is 0.45 millimeter, and blade rear end angular radius R is 0.38 millimeter.

The beneficial effects of the utility model are: can guarantee that part finishes the processing of groove outside the part front end face in a clamping, avoid multiple clamping or repeatedly tool changing, improve working (machining) efficiency, solve the same problem that existing part work in-process exists.The utility model is applicable to thick middle, and thin, the processing of the outer groove of two ends cylindrical complicated parts end face simultaneously in two ends is applicable to the processing of obturaging the class part for a short time in other words.

Description of drawings

Fig. 1 is the overall structure schematic diagram of utility model knife bar that cutter is installed.

Fig. 2 is the workpiece structural representation behind the utility model cutter processing parts.

Among Fig. 33 is utility model cutter partial structurtes and user mode figure.

Above-mentioned number in the figure explanation: the 1. right hand (choosing right hand knife bar) knife bar, 2. clamping securing member, 3. blade (utility model cutter), 4. end face groove according to part shape.Among specification and the figure not dimensioning unit be mechanical industry millimeter unit commonly used.

The specific embodiment

As shown in Figure 1, insert blade 3, and fix composition novel numerical control car processing and forming dedicated tools with clamping securing member 2 by knife bar 1 front end.In a clamping, finish the processing that the whole end face groove 4 of class part is obturaged in processing for a short time.

As shown in Figures 2 and 3, this typically for a short time obturaging during part of processing, originally blade width is 1.27 ± 0.01 millimeters, pricks end face groove 4 at every turn, all the dimension overproof phenomenon can occur.It is 1.17 millimeters now with the transformation of the way of blade 3 width, blade nose angle radius R is 0.45 millimeter, blade rear end angular radius R is 0.38 millimeter, one cutter is just intact with whole end face groove 4 type cars, 4 li each sizes of end face groove have been guaranteed after the processing, can realize that precision is: groove width is 1.219 ± 0.1 millimeters, and the nose angle radius R is 0.457 ± 0.08 millimeter in the groove, and angular radius R in rear end is 0.38 ± 0.12 millimeter in the groove.

Claims

1. numerical control car processing and forming cutter, insert blade (3) by knife bar (1) front end, and form with clamping securing member (2) is fixing, it is characterized in that: blade (3) width is 1.17 millimeters, blade nose angle radius R is 0.45 millimeter, and blade rear end angular radius R is 0.38 millimeter.
