With.When needing flexible clamping on some non-standard equipments in use, just needing that small, light weight, simple in structure, cost is lower
Fast automatic fixture.This collet should have light, accurate, reliable performance, can realize quick-clamping, and clamping and
The position of workpiece itself is not impacted when release or even the angle of its rotation should also accomplish can control.By to elasticity
The flexible utilization of collet is clamped using pneumatic device and above functions may be implemented with synchronous belt structure driven.
Utility model content
For solution, pneumatic and oild chuck structural volume is big in the prior art, cost is high, is not suitable for non-standard automatic clamping
The problem of use, the utility model provide a kind of rotatable pneumatic chuck of workpiece.
To achieve the above object, the utility model adopts the following technical solution：A kind of rotatable pneumatic chuck of workpiece, packet
Collet, main shaft and mounting base are included, has through-hole I, main shaft to pass through the through-hole I inside mounting base, be arranged inside main shaft inside mounting base
Be useful for placing the through-hole II of workpiece, both sides are fixedly mounted respectively there are one there is a cylinder mounting base up and down, main shaft one end with install
The adjacent position of seat is equipped with synchronizing wheel, collet is equipped in the through-hole II of main shaft other end end, the outside of collet is provided with
Sliding sleeve, is fixed with mounting plate on sliding sleeve, and piston rod one end of the mounting base cylinder of both sides up and down is fixed on a mounting board.
A bearing I is respectively fixed at the orifice position of mounting base both ends.
Sliding sleeve one end is fixed on collet, and the sliding sleeve other end is fixed on main shaft, and bearing II is provided on sliding sleeve
And axle sleeve, mounting plate are fixed on by bearing II and axle sleeve on sliding sleeve.
The collet is truncated conical shape, and the diameter of the minor diameter end face of truncated cone-shaped collet is less than the straight of the through-hole II of main shaft
Diameter is arranged outside spindle through-hole II, and the diameter of the major diameter end face of truncated cone-shaped collet is more than the diameter of the through-hole II of main shaft, if
It sets inside spindle through-hole II.
The collet is flexible collet.
The beneficial effects of the utility model are：The utility model provides a kind of rotatable pneumatic chuck of workpiece, structure
Size is small, and manufacturing process is simple, is suitble to the quick-clamping of the cylindrical work within the scope of specific dimensions, and does not limit workpiece
Length can have in the design and manufacture of non-standard automatic clamping than wide and flexible application.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the internal cross section figure of Fig. 1.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figs. 1-2, the utility model provides a kind of rotatable pneumatic chuck of workpiece, including collet 11,2 and of main shaft
Mounting base 4 has inside mounting base 4 through-hole I, main shaft 2 that the through-hole I inside mounting base 4, main shaft 2 is passed through to be internally provided with for putting
The through-hole II of workpiece 1 is set, a bearing I 6, about 4 both sides of mounting base difference are respectively fixed at 4 both ends orifice position of mounting base
There are cylinder 5,2 one end of main shaft position adjacent with mounting base 4 that synchronizing wheel 3,2 other end end of main shaft are installed there are one being fixedly mounted
Collet 11 is installed in the through-hole II of head, collet 11 is truncated conical shape, and the outside of truncated cone-shaped collet 11 is provided with sliding sleeve 10,
10 one end of sliding sleeve is fixed on truncated cone-shaped collet 11, and 10 other end of sliding sleeve is fixed on main shaft 2, is fixed on sliding sleeve 10
Mounting plate 8 is provided with bearing II 7 and axle sleeve 9 on sliding sleeve 10, and mounting plate 8 is fixed on sliding sleeve by bearing II 7 and axle sleeve 9
On 10, piston rod one end of the cylinder 5 of about 4 both sides of mounting base is fixed on mounting plate 8.
The diameter of the minor diameter end face of truncated cone-shaped collet 11 is less than the diameter of the through-hole II of main shaft 2, is arranged in 2 through-hole of main shaft
Outside II, the diameter of the major diameter end face of truncated cone-shaped collet 11 is more than the diameter of the through-hole II of main shaft 2, is arranged in 2 through-hole of main shaft
Inside II.
Collet 11 is flexible collet, and is the conical surface with the contact surface of sliding sleeve 10, and 1 clamping of workpiece is in collet 11
On, when the conical surface is compressed, endoporus will be shunk.
The operation principle of the utility model is as follows：When two cylinders 5 are in release state, collet 11 is in free shape
State belongs to clearance fit with workpiece 1, and workpiece 1 can be moved freely through and be removed.When two cylinders 5 are in retracted state, even
Fishplate bar 8 drives sliding sleeve 10 to be slided to 11 direction of elastic collet, since the contact surface of elastic collet 11 and sliding sleeve 10 is the conical surface,
Elastic collet 11 will deform under the effect of the pressure of cylinder, and endoporus reduces to generate the interference fit with workpiece 1, just presss from both sides in this way
Tight workpiece 1.
After workpiece 1 is clamped, synchronizing wheel 3 drives main shaft 2 to rotate under exterior power, due to bearing I 6 and bearing II 7
Support, may be implemented workpiece 1 fastening and high speed rotation, to realize high-precision clamping and processing.
The above is preferred embodiments of the present invention, it is noted that for those skilled in the art,
The present utility model is not limited to the above embodiments, under the premise of not departing from the utility model general idea, can also make
Several changes and improvements, these should also be considered as the scope of protection of the utility model.
