Abstract

The utility model relates to a parts machining field relates to the field of adopting vertical milling machine processing part. The utility model discloses an adaptation is in fan -shaped breach milling fixture of vertical milling machine's disc part, milling fixture are the ring platform, have milling cutter walking groove along radially opening on the one of which side end face, and still two constant head tanks have been offered to the symmetry on with the side end face, and it has the feather key mounting groove to open on the terminal surface of its opposite side. Compare in the processing of original adoption circular table, adopt the utility model discloses a supplementary operating time of rotary location has been saved to the milling fixture, and overall machining efficiency can improve. And simultaneously, the utility model discloses a mode still has the beneficial effect that intensity of labour is little.

Description

Adapt to the disk-shaped part sector notch milling fixture of vertical knee-type milling machine

Technical field

The utility model relates to part manufacture field, relates to the field adopting vertical knee-type milling machine processing parts specifically.

Background technology

In the utility model, the disk-shaped part of indication is along porose disk-shaped part uniform in disk concentric circumferences.What it needs be processed to form is a sector notch with certain angle, and concrete shape can reference diagram 1.

In the past when processing this kind of part, by circular table clamping workpiece, then by hand dynamic dividing arm calibration, milling operation must be completed.

This method not only labour intensity is large, and inefficiency.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of milling fixture being exclusively used in processing ring-shape accessory sector notch newly, thus can reduce labour intensity, and increases work efficiency.

In order to realize this purpose, we disclose the disk-shaped part sector notch milling fixture adapting to vertical knee-type milling machine, milling fixture is annulus platform, one side end face radially has a milling cutter walking trough, on same side end face, also symmetry offers two locating slots, and the end face of its opposite side has feather key mounting groove.

So-called annulus platform refers to have certain circular ring, and it has upper and lower two end faces respectively, and inner circle sidewall and cylindrical sidewall.

The end face of its side has a milling cutter walking trough, thus when making workpiece thereon, milling cutter along this walking trough operation, can realize the milling of workpiece, thus the degree of depth of this cell body is wanted workpiece milling to be led to when can ensure milling cutter operation.

Symmetry is also wanted to start there are two locating slots at the same side end face of milling cutter walking trough.

These two locating slots offer the needs that position will coordinate workpiece to be processed, the angle between locating slot needs identical with the angle of workpiece sector notch, while two locating slots lay respectively on the side reverse extending line of sector notch.

Further, we also disclose described guide key groove correspondence and are provided with two.

After adopting technical scheme disclosed in the utility model, and originally adopted compared with circular table, save the overhead time that revolution is located, overall working (machining) efficiency is improved.Meanwhile, mode disclosed in the utility model also has the little beneficial effect of labour intensity.

Detailed description of the invention

As shown in Figure 2, adapt to the disk-shaped part sector notch milling fixture of vertical knee-type milling machine, milling fixture is annulus platform, its upper surface radially has a milling cutter walking trough 1, on end face, also symmetry offers two locating slots 2 equally thereon, in figure 3, we see have feather key mounting groove 3 on its lower surfaces.

According to the mode of Fig. 3, first a feather key 4 loads in feather key mounting groove 3 by we, then loads in the locating slot in the middle part of milling machine table by feather key 4, places block 5 respectively in the both sides of milling fixture, and block 5 will be close to milling fixture cylindrical sidewall.The position of adjustment slotting cutter 6, makes the radial operation along milling fixture when bus crosses feed on the right side of it.

Workpiece 7 to be processed is contained on milling fixture by the mode in Fig. 3, simultaneously with reference to figure 4, alignment pin 8 is inserted in the hole of workpiece to be processed 7 by we, we need the position according to considering milling sector notch herein, and the hole that alignment pin 8 inserts will on the reverse extending line of sector notch side place.After being plugged alignment pin 8, turning of work piece 7, makes alignment pin 8 proceed in locating slot 2, falls alignment pin 8, and the position to be processed of workpiece 7 is fixed.

Then according to the mode in Fig. 3, be respectively charged into T-shaped block 9, double threaded screw 10, cushion block 11, pressing plate 12, pad 13, nut 14, fastening nut 14 after installing, thus complete the Set and Positioning of workpiece 7.

Start slotting cutter 6, milling machine table 15 crosses feed, and completes the milling operation of sector notch side.As shown in Figure 4, the milling operation on what it completed is A limit.

Then, we exit slotting cutter 6 fast, milling machine table 15 is moved to the left a milling cutter diameter distance, unclamp pressing plate 12, pull up alignment pin 8, make the locating slot 2 that it departs from fixture, rotate workpiece to be processed 7, make alignment pin 8 fall into an other locating slot 2, then fall alignment pin 8, second position to be processed of workpiece 7 is determined.

Repeat according to the mode in Fig. 3, be respectively charged into T-shaped block 9, double threaded screw 10, cushion block 11, pressing plate 12, pad 13, nut 14, fastening nut 14 after installing, thus complete the Set and Positioning of workpiece 7.

Start slotting cutter 6, milling machine table 15 crosses feed, and completes the milling operation of sector notch side.As shown in Figure 4, the milling work on its B limit completed.

Thus, complete whole part sector notch milling operation.
