Abstract
The invention discloses a clamping device for inner holes of specially-structured thin-wall workpieces. The clamping device comprises a supporting shaft, wherein one end of the supporting shaft is mounted at a tail seat of a lathe, and three hydraulic oil cylinders are fixed on the peripheral wall of the other end of the supporting shaft and are distributed at a 120-degree interval along the circumference of the supporting shaft; piston rods of the hydraulic oil cylinders are fixedly connected with an inner arc-shaped surface of an circular arc-shaped supporting plate. By virtue of an arc-shaped supporting device with the adjustable supporting radius, the inner holes of the specially-structured thin-wall workpieces at two ends of the clamping device can be clamped, so that the subsequent process machining or assembling is facilitated, and the clamping is stable and reliable.
Description
Technical field
The invention belongs to a kind of clamping device, be specifically related to a kind of thin-wall workpiece endoporus clamping device of special construction.
Background technology
For the thin-wall workpiece of some special construction, one end diameter is less, and other end diameter is larger, when adding man-hour to the larger one end of diameter, adopts traditional mandrel class clamping mode can not realize the clamping of one end that diameter is larger; And because workpiece is too small, can not carry out outer surface clamping and axial grip, how to ensure that the location of workpiece and clamping become a problem that needs solution.
Summary of the invention
The present invention proposes in order to overcome the shortcoming existing in prior art, its objective is a kind of thin-wall workpiece of special construction endoporus clamping device is provided.
Technical scheme of the present invention is:
A thin-wall workpiece endoporus clamping device for special construction, comprises back shaft, and the periphery wall of one end of back shaft is fixed with three hydraulic jacks, and three hydraulic jacks are 120 ° of distributions along back shaft excircle; The piston rod of hydraulic jack is fixedly connected with the intrados of circular arc gripper shoe.
The external diameter of described gripper shoe is identical with the internal diameter of workpiece.
The arc length of described gripper shoe is less than 1/3rd of inner hole of workpiece girth.
Described gripper shoe adopts polyformaldehyde manufacture.
The invention has the beneficial effects as follows:
The present invention is by a kind of adjustable arc bracing or strutting arrangement of radius that supports, and the endoporus that can complete the special construction thin-wall workpiece different to two ends diameter clamps, and is convenient to following process or assembling work, clamps stable, reliable.
Brief description of the drawings
Fig. 1 is front view of the present invention;
Fig. 2 is the top view of original state of the present invention;
Fig. 3 is the top view of clamped condition of the present invention.
Wherein:
1 back shaft 2 hydraulic jacks
3 gripper shoe 4 workpiece.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the thin-wall workpiece endoporus clamping device of special construction of the present invention is elaborated:
As shown in Fig. 1 ~ 3, a thin-wall workpiece endoporus clamping device for special construction, comprises back shaft 1, and one end of back shaft 1 is installed on the tailstock of lathe, other end periphery wall is fixed with 2, three hydraulic jacks 2 of three hydraulic jacks and is 120 ° of distributions along back shaft 1 excircle; The piston rod of hydraulic jack 2 is fixedly connected with the axle center of the intrados of circular arc gripper shoe 3.
The external diameter of described gripper shoe 3 is identical with the internal diameter of workpiece 4.
The arc length of described gripper shoe 3 is less than 1/3rd of workpiece 4 endoporus girths.
When hydraulic jack 2 original state, piston rod shrinks, three gripper shoes 3 are near state, and the arc length of gripper shoe 3 can ensure that the position radius of three gripper shoes 3 is now less than the radius of thin-wall workpiece 4 smaller-diameter portion, can ensure that gripper shoe 3 can pass from inner hole of workpiece.
Described gripper shoe 3 adopts polyformaldehyde manufacture.
Use procedure of the present invention:
Back shaft 1 is arranged on to the tailstock position of lathe, workpiece 4 is positioned on the parts that can move on lathe guide rail; When workpiece 4 completes behind location, mobile tailstock, three gripper shoes 3 that the other end of back shaft 1 is installed are passed from workpiece 4 endoporus; Gripper shoe 3 arrives after assigned address, and hydraulic jack 2 piston rod work make gripper shoe 3 contact with workpiece 4 inwalls and clamping work pieces 4. Then can process or assembling work workpiece 4.
