Description

A kind of circular ring shape cutter binding clasp

Technical field

The utility model relates to tool mounting more particularly to a kind of fixtures of circular ring shape cutter.

Background technique

In special process cutting field, a kind of cutter of annulus shape is needed, which is hollow annular shape, cutting position In annular portion, since its shape is special, using traditional locking method, for example binding clasp is used, be difficult to fix, even if reluctantly It is clamped using binding clasp from the intermediate position of annulus, blade is also easy to appear the problem of alignment difference, and alignment difference cannot be steady Fixed cutting, loosens, and skids on fixture, can not complete cutting task.These problems have perplexed answering for this kind of cutter With.

Utility model content

The purpose of this utility model is to solve the clamping problems of circular blade for such problem, design a kind of annulus The cutter binding clasp of shape, the utility model are by newly designing the special boss being used cooperatively of one kind and containing reeded folder Tool, blade is entrapped on boss, then is clamped by bolt, solves the clamping problems of circular blade.

The design of the utility model is: a kind of circular ring shape cutter binding clasp is made of taper shank, fixture, has one in the middle part of taper shank A flange, the diameter of the flange are greater than the maximum gauge of taper shank, and the left end of flange is the big cylinder in the small inside in an outside Shape boss, there is bolt hole in the center of the boss, and the maximum gauge of boss is less than the diameter of flange, inside the fixture There is the groove matched with the boss, there is a location hole at the center of the fixture, and bolt can pass through the location hole, Boss upper bolt hole is screwed into be attached.

The blade for being caught in a kind of annular can be covered on boss, the interior annular of blade can just cover on boss.

Preferred boss cross section is round, the more convenient processing of such boss, while more with the fitness of blade It is good.

The diameter of the preferred blade interior annular is greater than boss top diameter, is less than boss root diameter (RD).As long as knife The internal radius of piece can cover convex platform, so that it may use the clamp.

It is preferred that the cross section of the flange is circular.

First by the blade sleeve convex platform of circular ring shape when use, then by fixture from the left side press convex platform, then passed through with bolt Location hole on fixture is tightened in the bolt hole at boss center, the adjustment position that at this moment blade can be adaptive, toward the interior of boss Side compression, what may finally be fastened locks on boss, while can satisfy alignment and stability two requirements.It finally will cone Handle, which is mounted on, to be needed to use in rotary shaft to be used.

The utility model has the advantages that

1, the utility model design is simple, cheap, and maintenance is facilitated to replace.

2, the clamping device of the utility model design, is adapted to the installation of the circular shear blade of different annular diameter, can be with Adaptive completion is coaxial and fixed, and versatility is high.

3, the utility model design solves the clamping problems of circular cutter, expands its adaptable field.

Detailed description of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Fig. 1 is the structural scheme of mechanism of the utility model

Fig. 2 is the assembling figure of the utility model

Fig. 3 is circular ring shape blade involved in the utility model

Wherein: 1 is taper shank, and 2 be flange, and 3 be fixture, and 4 be boss, and 5 be bolt hole, and 6 grooves, 7 be location hole, and 8 are Bolt, 9 blades.

Specific embodiment

Embodiment 1:

A kind of circular ring shape cutter binding clasp is made of taper shank 1, fixture 3, there is a flange 2 in the middle part of taper shank 1, and described is convex The diameter of edge 2 is greater than the maximum gauge of taper shank 1, and the left end of flange 2 is the big cylindrical boss 4 in the small inside in an outside, boss 4 Center in have a bolt hole 5, the maximum gauge of boss 4 is less than the diameter of flange 2, has one inside fixture 3 and boss 4 matches Groove 6, there is a location hole 7 at the center of fixture 3, and bolt 8 can pass through the location hole 7, be screwed into 4 upper bolt hole 5 of boss into Row connection.The blade 9 for being caught in a kind of annular can be covered on boss, the interior annular of blade 9 can just cover on boss 4.It is convex 4 cross section of platform is round.

Since the diameter of flange 2 is greater than the maximum gauge of taper shank 1, so, install on the rotary shaft, whirler anyway Structure will not all damage blade, since the maximum gauge of boss 4 is less than the diameter of flange 2, so no matter how about, annular blade is all It is stuck on boss 4, will not also be slipped to 1 side of taper shank, be arranged so very safe.

First by 9 sets of convex platforms 4 of the blade of circular ring shape when use, then by fixture 3 from left side pressure convex platform 4, then with bolt 8 Location hole 7 on fixture 3 is tightened in the bolt hole 5 at 4 center of boss, the adjustment position that at this moment blade 9 can be adaptive, Toward the interior side compression of boss 4, what may finally be fastened is locked on boss 4, and being finally mounted on taper shank 1 needs rotation to be used It can be used on axis.

Claims (5)
