The aligner comprises a round tail handle matched with a milling cutter chuck and a measurement part which is positioned below the round tail handle; the measurement part is provided with an inverted V-shaped nip mouth capable of holding parts to be processed; and the inverted V nip mouth is symmetrical relative to an axis of the round tail handle. The utility model has the advantages that firstly, the defects of low cutting precision and slow speed of incision visual inspection are overcome; secondly, the technical requirements for operators are reduced and the processing quality of a keyway is guaranteed; and thirdly, the labor productivity is improved. The utility model is applied to a milling machine, and is mainly suitable for the parts with higher symmetrical precision requirements for processing, wherein the symmetrical precision can reach 0.025-0.015 mm.

Description

Keyway processing alignment device

Technical field

The utility model relates to a kind of milling machine processing keyway part, when this part can be guaranteed with milling cutter processing keyway, and quick, accurately tool setting.

Background technology

In machine industry, often run on axial workpiece, process keyway with milling machine.But in keyway processing, there is the problem of how tool setting.Promptly the axis of cotter mill cutter to positive axis, the symmetry that the keyway that guarantees to process meets design requirement.Because the symmetry of keyway is to guarantee the necessary condition of assembling smoothly, its crudy directly has influence on the performance and the service life of whole device, thus in the processing all be by every possible means cotter mill cutter and spool axis align, to satisfy the designing requirement of part.

Generally all be to adopt the cut channel ocular estimate to carry out tool setting now, tool setting speed is slow, and precision is low, and operator's technical merit is required height, and the symmetry precision can only reach 0.05～0.10mm, does not reach the required precision of 0.025～0.015mm of designing requirement.

The utility model content

Low to skill in using a kitchen knife in cookery precision in order to overcome above-mentioned cut channel range estimation, slow-footed shortcoming reduces the specification requirement to the operator, and the utility model provides a kind of and is convenient to the quick tool setting of milling cutter, and tool setting keyway processing accurately alignment device.

To achieve these goals, the technical solution of the utility model is as follows:

Alignment device is used in keyway processing, it is characterized in that: comprise

The one rounded tail handle that matches with the milling cutter chuck;

And a measure portion that is positioned at rounded tail handle below, described measure portion is provided with " ∧ " folder mouthful that can hold part to be processed, described " ∧ " folder mouthful axis symmetry about the rounded tail handle.

Further, in the utility model, the angle of described " ∧ " folder mouth is 50 degree-70 degree.

Further, in the utility model, the gripping edge section shape of described " ∧ " folder mouthful is tapered, and the width of its outer is 0.5mm-1mm.

The beneficial effects of the utility model are:

1. it is low to skill in using a kitchen knife in cookery precision that the utility model has overcome the cut channel range estimation, slow-footed shortcoming;

2. reduce specification requirement, guarantee the crudy of keyway the operator;

3. improved labor productivity.

The utility model is applied on the milling machine, mainly is applicable to the higher part of the symmetrical required precision of processing, and symmetrical precision can reach 0.025mm～0.015mm.

Description of drawings

Describe the utility model in detail below in conjunction with the drawings and specific embodiments:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the lateral plan of Fig. 1;

Fig. 3 is that the A-A of Fig. 1 is to partial sectional view;

Fig. 4 is user mode figure of the present utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Referring to Fig. 1,2 and 3, keyway processing is made up of rounded tail handle 11 and measure portion 12 with alignment device 10.

The diameter of rounded tail handle 11 is the same with the diameter of milling cutter afterbody, all matches with the milling cutter chuck.In the utility model, the diameter of rounded tail handle 11 is Φ 20, highly is 40mm.

Measure portion 12 is positioned at rounded tail handle 11 belows, and measure portion 12 and rounded tail handle 11 can the one moulding by casting, also can be by being welded together.Measure portion 12 is provided with " ∧ " folder mouth 121, should can be used to hold part to be processed by " ∧ " folder mouth 121, " ∧ " folder mouth 121 axis 111 symmetries about rounded tail handle 11.In the present embodiment, the angle of " ∧ " folder mouthfuls 121 is 60 degree, and gripping edge 122 section shapes of " ∧ " folder mouthfuls 121 are tapered, and the width of its outer 123 is 0.5mm-1mm.

In the utility model, upper end (minimum) width that is somebody's turn to do " ∧ " folder mouth is 18mm, and lower end (maximum) width is 50mm.

During use, earlier with keyway processing of the present utility model with on rounded tail handle 11 clampings of the alignment device 10 milling cutter chuck to the milling machine spindle, note not too tight (so that can rotate by hand) of folder, mobile then part to be processed or milling cutter chuck, make part to be processed 20 roughly be positioned at " ∧ " folder mouthful 121 (as shown in Figure 4) of alignment device, further debug the position of milling cutter chuck again, two gripping edges until " ∧ " folder mouth 121 all contact with the cylindrical of part to be processed 20, at this moment, the line of symmetry of " ∧ " folder mouth and the axis of part to be processed are positioned at same plane, and vertical mutually.Certainly, also can make part to be processed equate (can adopt light transmission method or clearance gauge to detect) with the gap of " ∧ " Jia Kou both sides, judge the symmetry of processing parts.

And then vertical mobile milling cutter chuck, make alignment device 10 risings and leave part to be processed 20, alignment device is taken off, change milling cutter, can carry out keyway processing.

The utility model mainly is applicable to the higher part of the symmetrical required precision of processing, whole tool setting process simple and fast, and the keyway that processes symmetry precision can reach 0.025mm～0.015mm, satisfies the designing requirement of part fully.And the specification requirement to the operator is not high, has improved labor productivity.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in the foregoing description and the specification is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
