Description
Technical field
The utility model is related to machining equipment field, and in particular to a kind of main shaft clamping 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 requirement is also improved 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, because scroll chuck or chuck have certain mass, when high speed rotates, because centrifugal force is made
It can all increase into the recessive problem of clamping imbalance etc., and three claws or four claws and groove is radially slided during long-term production
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 process can produce adhesion in the face that tightens of three claws or four claws, cause thirdly claw or pintongs
The clamping dynamics of pawl is uneven, so as to cause axiality bad.
Utility model content
In order to solve the above technical problems, we have proposed the main shaft grasping system that a kind of suitable high speed rotates turning, this is
System is simple in construction, can keep high-precision coaxial, and clamping is stable, and reliability is high, and service life is long, is hardly damaged.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：A kind of main shaft folder of suitable high speed rotation turning
Hold system, including rotating in air oil cylinder, turning main shaft, main shaft support seat, hollow pull rod, terminal pad, elastic flange disk and eight valves
Pawl chuck；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
Portion, the turning main-shaft spindle head outer face is provided with the terminal pad, and the terminal pad outer face is provided with the elastic flange
Disk, the elastic flange disk outer face is provided with the eight claws chuck, and the hollow pull rod is placed through in the turning main shaft,
Its one end is connected on the elastic flange disk inner face, and the other end is connected with the rotating in air oil cylinder output end.
It is preferred that, the hollow pull rod, elastic flange disk and eight claw chucks are coaxially disposed with the turning main shaft respectively.
It is preferred that, 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 utility model is driven described by the rotating in air oil cylinder when moving forward and backward
Hollow pull rod moved forward and backward, and strutting or retracting for the elastic flange disk is controlled by moving forward and backward for hollow pull rod
Deformation, and then the release or clamping of the eight claws chuck are controlled, such grasping system can keep processing workpiece and turning
Main shaft is coaxial in high precision, improves the precision and quality of processing workpiece, and the system operatio is simple, is hardly damaged, service life compared with
It is long, and clamping is stable, reliability is high, greatly reduces production cost, improves economic benefit.
