Description
Technical field
The present invention relates to machine tool fields, and in particular to a kind of clamping mechanism of numerically controlled lathe.
Background technique
It is three-jaw self-centering chuck and four paws chucks, both chucks difference that numerically-controlled machine tool, which commonly grabs folder mode,
For round shaft-like workpiece and the clamping of special-shaped workpiece, and only once positioning and clamping, there is no secondary locking mechanism, in addition
Since clamping jaw is more, the contact surface between workpiece is smaller, therefore pressure is very big, it is easy to destroy workpiece surface, clamping jaw is excessive
So that the structure of chuck is more complicated, increased costs, operation difficulty increases, and scroll chuck can not clamping special-shaped workpiece, use
Limitation.
Summary of the invention
That technical problem to be solved by the invention is to provide a kind of use scopes is wide, can the different type of clamping workpiece,
It is convenient for mounting and clamping, and secondary locking mechanism is set, increase clamping ability.
The present invention is achieved through the following technical solutions: a kind of clamping mechanism of numerically controlled lathe, including lathe main body
And it is installed on the clamping mechanism on lathe, which includes a pawl disk and two folders for being set to two sides inside pawl disk
Pawl, the intermediate of the pawl disk form a clamping chamber, open up a card slot on the bottom surface of clamping chamber, and the top of clamping jaw is from clamping
Intracavitary to be incorporated in card slot, the setting of the pawl disk outboard end of face card slot is packed into a bolt in bolt hole there are two bolt hole,
Bolt screws in bolt hole and contacts compression with the top surface of clamping jaw, and the centre of clamping jaw is additionally arranged at one or more secondary limit
Bar.
The secondary gag lever post is provided at least two as a preferred technical solution, is arranged at least two in each clamping jaw
The secondary gag lever post of root, the secondary gag lever post are a clamping screw, are installed in the groove that pawl disk lateral surface opens up, secondary
Gag lever post passes through the bottom of screw thread rotation to clamping jaw and compresses across the lateral surface of clamping jaw and workpiece.
The bottom of the clamping jaw is provided with two clamping plates as a preferred technical solution, is in " V "-shape between two clamping plates, work
Part is incorporated between two clamping plates.
The medial surface of the clamping plate is provided with one piece or more of protrusion as a preferred technical solution, and protrusion is laid
It is placed in the medial surface of clamping plate.
The secondary gag lever post is set to the medial surface of two bolts, stud base and folder as a preferred technical solution,
The top end surface of pawl compresses.
The beneficial effects of the present invention are: the configuration of the present invention is simple, can be used in the uniform tool of clamping or clamping abnormity
The workpiece of class increases the type of clamping workpiece, and carries out secondary positioning by secondary gag lever post, has very superior clamping
Ability, clamping are also more convenient.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is top view of the invention.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As depicted in figs. 1 and 2, including lathe main body and the clamping mechanism being installed on lathe, which includes
One pawl disk 1 and two clamping jaws 2 for being set to 1 inside two sides of pawl disk, the intermediate of pawl disk 1 form a clamping chamber, clamping chamber
A card slot is opened up on bottom surface, the top of clamping jaw 2 is incorporated in card slot from clamping is intracavitary, and the pawl disk outboard end of face card slot is set
It sets there are two bolt hole, a bolt 3 is packed into bolt hole, bolt 3 screws in bolt hole and contacts pressure with the top surface of clamping jaw 2
Tightly, the centre of clamping jaw 2 is additionally arranged at one or more secondary gag lever post 4.
In the present embodiment, secondary gag lever post 4 is provided at least two, and at least two secondary limits are arranged in each clamping jaw 2
Bar 4, secondary gag lever post 4 are a clamping screw, are installed in the groove 9 that pawl disk lateral surface opens up, secondary gag lever post 4 passes through
Screw thread rotation to clamping jaw bottom and pass through the lateral surface of clamping jaw and workpiece and compress, after clamping jaw and workpiece 6 clamp, then rotation lock
Tight bolt enables its bottom and the surface of workpiece to compress, secondary limit, and clamping ability is more excellent.
Wherein, the bottom of clamping jaw is provided with two clamping plates 5, is in " V "-shape between two clamping plates 5, and workpiece 6 is incorporated in two clamping plates 5
Between, secondary gag lever post 4 is set to the medial surface of two bolts, the top end surface compression of 3 bottom of bolt and clamping jaw, due to two folders
Pawl one end is provided with " v " shaped clamping plate, can empty face with the complete rear appearance one of clamping workpiece, therefore can be used for clamping
There is the special-shaped part of protrusion in part, and if it is cylindrical standard part, clamping, very simple side can be realized by V-type clamping jaw
Just.
Wherein, the medial surface of clamping plate is provided with one piece or more of protrusion 7, and protrusion 7 is uniformly arranged the medial surface in clamping plate,
By these protrusions, the chucking power between workpiece can be effectively increased.
The beneficial effects of the present invention are: the configuration of the present invention is simple, can be used in the uniform tool of clamping or clamping abnormity
The workpiece of class increases the type of clamping workpiece, and carries out secondary positioning by secondary gag lever post, has very superior clamping
Ability, clamping are also more convenient.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
