Description
Technical field
The present invention relates to machining equipment field, and in particular to a kind of main shaft clamping system of suitable high speed rotation turning
System.
Background technology
With the development of machinery industry, bounce of the people to the main shaft grasping system of numerically controlled lathe under high speed rotational case
Balance requires also to improve therewith, and the main main shaft method of clamping of numerically controlled lathe is typically using accurate scroll chuck in the market
Or chuck is clamped, as scroll chuck or chuck have certain mass, when high speed rotates, because centrifugal force is made
Can all increase into the recessive problem of clamping imbalance etc., and during long-term production three claws or four claws with radially slide groove
Fit clearance also because abrasion can be increasing, so as to cause precision and concentricity to decline, and this method of clamping is because cutting
The chip produced in liquid or the course of processing can produce adhesion in the face that tightens of three claws or four claws, cause its three claw or pintongs
The clamping dynamics of pawl is uneven, so as to cause axiality bad.
The content of the invention
To solve above-mentioned technical problem, the main shaft grasping system that a kind of suitable high speed rotates turning is we have proposed, this is
System simple structure, can keep high-precision coaxial, and clamping is stable, and reliability is high, and long service life, is hardly damaged.
To reach above-mentioned purpose, technical scheme is as follows：A kind of main shaft clamping system of suitable high speed rotation turning
System, presss from both sides including rotating in air oil cylinder, turning main shaft, main shaft support seat, hollow pull rod, terminal pad, elastic flange disk and eight claws
Head；The turning main shaft is installed in the main shaft support seat, and the rotating in air oil cylinder is located at the turning main shaft tail, institute
State turning main-shaft spindle head outer face and the terminal pad is installed, the terminal pad outer face is provided with the elastic flange disk, institute
State elastic flange disk outer face and the eight claws chuck is installed, the hollow pull rod is placed through in the turning main shaft, one
End is connected on the elastic flange disk inner face, and the other end is connected with the rotating in air oil cylinder outfan.
Preferably, the hollow pull rod, elastic flange disk and eight claw chucks are coaxially disposed with the turning main shaft respectively.
Preferably, the restricted hollow pull rod displacement is set between the hollow pull rod and the turning main shaft
Position limiting structure.
By above-mentioned technical proposal, the present invention is described hollow by driving when moving forward and backward for the rotating in air oil cylinder
Pull bar moves forward and backward, by the change that struts or retract moved forward and backward to control the elastic flange disk of hollow pull rod
Shape, and then the release or clamping of the eight claws chuck are controlled, such grasping system can keep processing workpiece and turning master
Axle high accuracy is coaxial, improves the precision and quality of processing workpiece, and the system operatio is simple, is hardly damaged, and service life is longer,
And stable, reliability height is clamped, production cost is greatly reduced, economic benefit is improve.
Description of the drawings
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
Accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this

Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structure section view of the main shaft grasping system of a kind of suitable high speed rotation turning disclosed in the embodiment of the present invention
Schematic diagram.
In figure：1st, rotating in air oil cylinder 2, turning main shaft 3, main shaft support seat 4, hollow pull rod 5, terminal pad 6, bullet
Property ring flange 7, eight claw chucks 8, position limiting structure
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
With reference to embodiment and specific embodiment, the present invention is further detailed explanation.
As shown in figure 1, a kind of suitable high speed rotates the main shaft grasping system of turning, including rotating in air oil cylinder 1, turning master
Axle 2, main shaft support seat 3, hollow pull rod 4, terminal pad 5, elastic flange disk 6 and eight claw chucks 7；The turning main shaft 2 is installed
In the main shaft support seat 3, the rotating in air oil cylinder 1 is located at 2 afterbody of turning main shaft, 2 spindle nose of turning main shaft
Outer face is provided with the terminal pad 5, and 5 outer face of the terminal pad is provided with the elastic flange disk 6, the elastic flange disk
6 outer faces are provided with the eight claws chuck 7, and the hollow pull rod 4 is placed through in the turning main shaft 2, and its one end is connected to
On 6 inner face of elastic flange disk, the other end is connected with 1 outfan of rotating in air oil cylinder.
The hollow pull rod 4, elastic flange disk 6 and eight claw chucks 7 are coaxially disposed with the turning main shaft 2 respectively.
The spacing of restricted 4 displacement of the hollow pull rod is set between the hollow pull rod 4 and the turning main shaft 2
Structure 8.
By above-mentioned technical proposal, the present invention by the rotating in air oil cylinder 1 drive when moving forward and backward it is described in
