The utility model provides a take the problem of the difficult processing of arc groove of boss part.

Description

A kind of arc groove processing special-purpose milling cutter

Technical field

This utility model relates to a kind of milling cutter, belongs to machining technique field.

Background technology

Our factory has a product, its Fig. 1 and Fig. 2 to be asked for an interview to, trough root R5 and R8 garden degree of slipping over, and ensures not with standard milling cutter Requirement, because standard milling cutter length is inadequate, lengthens milling cutter stiffness inadequate, and two R of root is excessive.Employing digital control processing is subject to Auricle is interfered, and processes not in place, then it is right to use pincers worker polishing and pulling with sample to repair, time-consuming, arduously, science, quality are unstable；General Logical Milling Process there is also same problem.

Utility model content

In order to solve the problems referred to above, this utility model plain cutter is changed a social system, it is provided that a kind of arc groove processes special milling Cutter, solves a processing difficult problem for part in Fig. 1.

Processing trough typically uses turning, method for milling, and has in the whole circle of Fig. 1 product that a boss turning is bad to be added Work, the processing method only using milling, and this part trough is arc groove and root R5/R8 is round and smooth excessively adds for processing Difficulty, and interfered by auricle, processing does not reaches requirement.Only by changing process, utilize rotating disk and copying milling principle, then Utilize milling cutter to change a social system, common slotting cutter knife edge part is only stayed 13.

Specifically, arc groove of the present utility model processing special-purpose milling cutter, including blade, knife bar, taper shank, one end of knife bar is even Connecing taper shank, the other end of knife bar connects blade, and blade is made up of the curved blade of two sections of different arc radius, two sections of curved blades Between seamlessly transit.

More specifically, the width of knife edge part is 13mm, and the radian of two sections of curved blades is respectively R5 and R8.

Arc groove of the present utility model processing special-purpose milling cutter, filled up the blank of such milling cutter, solve garden arc groove connect R and Process problem not in place.The visual field of the cutter transformation of the way that this utility model is open, has promotional value, low cost, easily changes a social system, contracting The short process-cycle, steady quality.

1. milling cutters, 2. part, 3. rotating disk, 4. lathe, 1-1. taper shank, 1-2. blade, 1-3. knife bar in figure.

Detailed description of the invention

Milling cutter described in the utility model as shown in Figure 4, including blade 1-2, knife bar 1-3, taper shank 1-1, one end of knife bar 1-3 The other end of connecting taper shank 1-1, knife bar 1-3 connects blade 1-2, blade 1-2 by the curved blade group of two sections of different arc radius Become, seamlessly transit between two sections of curved blades.The width of knife edge part is 13mm, the radian of two sections of curved blades be respectively R5 and R8。

As long as special-purpose milling cutter achieves that the processing of part on ordinary vertical milling machine, installation way is as shown in Figure 3.Part 2 It is worked into state before heat treatment with other method and apparatus, on the basis of hole, is then contained in rotating disk 3 colonel just compresses, by adjusting Dao Yan garden arc is carried out arc groove processing, meets part requirements.

For this position arc groove processing analysis: digital control processing does not has corresponding cutter, need to customize two special Milling cutter time length, cost height there is also certain risk；Common plain milling can meet deep trouth and connect R processing problems, but can not meet Arc machining and auricle interference problem；By change processing technique of absorbing all the useful ideas, change system into special-purpose milling cutter with common slotting cutter, with On the basis of endoporus, arc end lies on rotating disk 3 upward, and by copying milling process principle, good cutter just can be carried out after compressing by correction Processing.

By changing a social system the processing of milling cutter, improve production efficiency, it is ensured that product quality, reduce production cost, meet Product requirement.

Claims (2)

1. an arc groove processing special-purpose milling cutter, it is characterised in that include blade, knife bar, taper shank, one end connecting taper shank of knife bar, The other end of knife bar connects blade, and blade is made up of the curved blade of two sections of different arc radius, flat between two sections of curved blades Slip over and cross.

Arc groove the most according to claim 1 processing special-purpose milling cutter, it is characterised in that the radian of two sections of curved blades is respectively For R5 and R8.
