Description

A kind of self-locking knife bar

Technical field

The utility model relates to the technical fields that machine tool is clamping, more particularly to a kind of knife bar.

Background technique

Cutter is made of cutting tip and retained part.If cutter is directly connected on lathe, a kind of same blade Knife, different retained parts need to be made into.This is clearly uneconomical, unpractical.Knife handle one end is connected on lathe, one end folder Cutter is held, then a large amount of combination that a small amount of cutter type of attachment and a small amount of knife handle type of attachment can generate can meet not Same demand.The appearance of clip type throw away chip makes the connection of blade and knife bar new problem occur.Mechanical clamped cutting blade is direct It is installed on knife handle, use cost can be made to increase.Currently, traditional machine tool knife handle is pressed from both sides generally by the way of hydraulic or spring strut Tight cutter, and clamp-on tool needs enough clamping carriers, therefore can occupy certain space, since the design of portioned product is asked Topic will appear interference, to cause the scrap problem of workpiece, therefore makes the use of traditional knife handle there are some problems.Knife bar one end Mountable mechanical clamped cutting blade makes original knife handle not be affected, if continually changing cutlery by the variation of knife bar, i.e., in fact Now our general exchange requirement.

Utility model content

For overcome the deficiencies in the prior art, the utility model provides a kind of self-locking knife bar, can reach it is easy for installation quickly, The purpose for avoiding product from interfering.

In order to achieve the above objectives, specific technical solution provided by the utility model is:

A kind of self-locking knife bar, comprising: self-locking spring, limit circle circlip, self-locking steel ball, steel ball from lock tube, chamfering blade one, Chamfering blade two；Self-locking knife bar one end is connected with fast lock knife handle matrix, and fast knife handle matrix of locking further is connected with knife handle；Self-locking knife The bar other end installs reamer.

In a kind of self-locking knife bar provided by the utility model:

Knife handle is connected on machine tool chief axis, functions as the carrier with cutter rotation；

Fast lock knife handle matrix is connect with knife handle, and blade can be changed quickly；

The effect of self-locking spring is that steel ball is pushed to move forward from lock tube, and it is outgoing to limit self-locking steel ball；

The effect for limiting circle circlip is the distance for limiting steel ball and sliding automatically from lock tube；

Self-locking steel ball is that limitation blade rotates in lock knife handle matrix fastly；

Steel ball is to limit the mobile device of steel ball from lock tube.

A kind of self-locking knife bar of the utility model, described in chamfering blade one can be become according to the demand of product to be processed More, the preferably 60 ゜ chamfering blades of chamfering blade one；

A kind of self-locking knife bar of the utility model, the chamfering blade two can be changed according to the demand of product to be processed, The preferably 60 ゜ chamfering blades of chamfering blade two.

The preferable PCD reamer of reamer or alloy type reamer.It can choose more suitable knife according to the difference of machined material Has material.

The utility model has the advantages that

1. a kind of self-locking knife bar of the utility model, can make original knife handle not be affected, continually changing cutlery Can be by structure provided by the utility model, to realize our general exchange requirement, the utility model structure is simple, operation It is convenient, it installs and uses fast, to improve working efficiency；

2. a kind of self-locking knife bar of the utility model, point diameter is smaller, can avoid the generation of the interference of product；

3. a kind of self-locking knife bar of the utility model, since manual tool changing can be used, do not need using auxiliary tool, it can It avoids that personal injury occurs in exchanging knives process.

Detailed description of the invention

Fig. 1 is a kind of main view of fast self-locking knife bar；

In figure:

1, knife handle 2, fast lock knife handle matrix 3, chamfering blade 1, chamfering blade two

5, self-locking spring 6, limit circle circlip 7, self-locking steel ball 8, steel ball from lock tube 9, reamer.

Specific embodiment

The utility model is further illustrated below by way of specific embodiment.

Embodiment 1

Using a kind of self-locking cutter arbor device shown in FIG. 1, comprising: self-locking spring 5 limits circle circlip 6, self-locking steel ball 7, steel Pearl is from lock tube 8, chamfering blade 1, chamfering blade 24；Self-locking knife bar one end is connected with fast lock knife handle matrix 2, fast to lock knife handle base Body 2 is further connected with knife handle 1；The self-locking knife bar other end installs reamer 9.

Chamfering blade one is 60 ゜ chamfering blades；Chamfering blade two is 60 ゜ chamfering blades.

Reamer 9 is PCD reamer.

The present embodiment has the advantages that

A kind of self-locking knife bar of the utility model, can make original knife handle not be affected, and continually changing cutlery is logical Knife bar is crossed, to realize our general exchange requirement, apparatus structure is simple, easy to operate, installs and uses more quick, improves Working efficiency；A kind of self-locking knife bar of the utility model, the diameter of front end is smaller, can avoid the generation of the interference of product；This A kind of self-locking knife handle of utility model, due to that can not need to can avoid sending out in exchanging knives process using auxiliary tool with manual tool changing Raw personal injury.

One embodiment of the utility model is described in detail above, but the content is only the utility model Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
