Description
Technical field
The present invention relates to a kind of ring body clamping device.
Background technology
Ring body adds man-hour requirement to clamp it in jin such as reconditionings, and existing ring body chucking device can only be by ring body axial direction two
End clamps, and the problem for existing is：First, ring body upper and lower surface is due to clamped equipment clamping, thus cannot be entered by equipment etc.
Row reprocessing；2nd, ring body center can not be accurately positioned, it is impossible to ensure the positional precision between process equipment and ring body center, hold
The form error easily caused after processing is larger.
The content of the invention
In view of the shortcomings of the prior art, the technical problem to be solved in the present invention is to provide a kind of ring body clamping device,
Ring body clip position high precision.
To achieve these goals, the present invention is to realize by the following technical solutions：A kind of ring body clamping device, bag
Include pedestal and on pedestal by the tightening mechanism of inner wall of ring body stretching, the tightening mechanism includes support arm, left and right briquetting and shifting
Motivation structure, the left and right briquetting can be slided along support arm and be symmetricly set on support arm center both sides, the travel mechanism drive it is left,
Right briquetting is moved along support arm and is pressed on inner wall of ring body radial direction two ends.
Further, the travel mechanism includes lift cylinders, body and left and right connecting rod, and the body is placed on lift cylinders
On piston rod, the two ends of the left and right connecting rod respectively with body and left and right rod hinge connection.
Further, annular groove is provided with the piston rod of the lift cylinders, the body includes inner sleeve and overcoat, described interior
Set is rotatably placed on outside annular groove, and the axial two ends of inner sleeve are fitted with the axial two ends of annular groove, the overcoat and inner sleeve
Between screw thread coordinate.
Beneficial effects of the present invention：
1st, ring body clamping device of the invention, clamps by inner wall of ring body, improves ring body positioning precision, and just
It is processed in ring body exterior surface；
2nd, ring body clamping device of the invention, moves, together while can just realizing two briquettings by a upgrading cylinder
Good, the high precision of step property.
Brief description of the drawings
Fig. 1 is a kind of structural representation of ring body clamping device of the invention；
Fig. 2 is the connection diagram of the body in a kind of ring body clamping device of the invention and lift cylinders.
Specific embodiment
For technological means, creation characteristic, reached purpose and effect for making present invention realization are easy to understand, with reference to
Specific embodiment, is expanded on further the present invention.
Figure is referred to, the present invention provides a kind of technical scheme：A kind of ring body clamping device, including pedestal 1 and positioned at pedestal 1
On by the tightening mechanism 2 of inner wall of ring body stretching, the tightening mechanism 2 includes support arm 21, left and right briquetting 22,23 and travel mechanism
24, the left and right briquetting 22,23 can be slided along support arm 21 and be symmetricly set on the center both sides of support arm 21, the travel mechanism 24
Drive left and right briquetting 22,23 to be moved along support arm 21 and be pressed on inner wall of ring body radial direction two ends.Left and right briquetting 22,23 it is relatively outer
Side is movable to the two ends of support arm 21 outside so as to being clamped to the inwall of ring body 100, as long as meeting the center of support arm and processing sets
Positional precision between standby ensures that the centralized positioning in ring body is accurate because ring body 100 by left and right briquetting 22,
After 23 clamp, the center of ring body 100 overlaps with support arm center.
Travel mechanism 24 includes lift cylinders 241, body 242 and left and right connecting rod 243,244, and the body 242 is placed on lifting
On the piston rod of cylinder 241, the two ends of the left and right connecting rod 243,244 are cut with scissors with body 242 and left and right connecting rod 243,244 respectively
Connect.The center of lift cylinders 241 and support arm center superposition, in the piston rod lifting process of lift cylinders 241, left and right connecting rod 243,
Under 244 effects, left and right briquetting 22,23 can synchronizing moving, it is and synchronous closer or far from can just be realized by a lift cylinders
The movement of left and right briquetting 22,23, control is simple, and left and right briquetting 22,23 synchronisms are good.
As shown in Fig. 2 being provided with annular groove 245 on the piston rod 2411 of lift cylinders 241, the body 242 includes inner sleeve 246
With overcoat 247, the inner sleeve 246 is rotatably placed on outside annular groove 245, and inner sleeve 246 axial two ends and annular groove 245
Axial two ends laminating, screw thread coordinates between the overcoat 247 and inner sleeve 246.The length of inner sleeve 246 is more than overcoat 247, due to interior
Set coordinates with sleeve thread, and inner sleeve 246 is axially spacing by annular groove 245, therefore, when rotating inner sleeve 246, overcoat 247 will rise
Drop, overcoat 247 lifts the position that can change left and right briquetting 22,23, that is to say, that in the case where piston rod 2411 is motionless,
The initial position of left and right briquetting 22,23 can be changed by rotating inner sleeve, so that when piston rod 2411 is lifted, Ke Yigai
Become the stroke of left and right briquetting 22,23, compressed such that it is able to the ring body to different inner diameters in larger interior diameter excursion.
General principle of the invention and principal character and advantages of the present invention has been shown and described above, for this area skill
For art personnel, it is clear that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing substantially from it is of the invention spirit or
