Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, right with reference to the accompanying drawings and embodiments
The present invention is described in further detail.It should be appreciated that described herein, specific examples are only used to explain the present invention, and does not have to
It is of the invention in limiting.
One kind of the present invention being followed by formula and clamps stroke adjustable hollow angling cylinder, as shown in Figs. 1-2, including oil cylinder shell
1, cylinder body 2, piston rod 3, clamp ring 4, pull rod 5 and position-limit mechanism 6, piston rod 3 is arranged in cylinder body 2, and and oil cylinder
Body 2 is slidably connected；I.e. when being passed through hydraulic oil, piston rod 3 can be axially moved along cylinder body 2.Piston rod 3 is hollow knot
Structure, clamp ring 4 are arranged in piston rod 3, form annular groove 31 with piston rod 3, the hollow knot in piston rod 3 is arranged in pull rod 5
In structure, the side wall of pull rod 5 protrudes above setting snap ring 51, and snap ring 51 is arranged in groove 31, by the reciprocating movement of piston rod 3,
Drive the reciprocating movement of pull rod 5.Position-limit mechanism 6 is arranged in the tail portion of cylinder body 2, and position-limit mechanism 6 is given up the throne after adjusting piston rod 3
It sets, to adjust the stroke of oil cylinder.Oil cylinder shell 1 is arranged outside cylinder body 2.
In one embodiment, it is provided with washer 32 in groove 31, the contact of snap ring 51 and 31 side wall of groove can be avoided, dropped
The abrasion of low-calorie ring 51.
In one embodiment, position-limit mechanism 6 includes spacing collar 61 and the fillet of screw 62, and the fillet of screw 62 is fixed with cylinder body 2 to be connected
It connects, spacing collar 61 is connected through a screw thread with the fillet of screw 62.By rotary stopper circle 61, straight line is switched to by rotary motion by screw thread
Movement changes the relative position of spacing collar 61 and the fillet of screw 62, and then changes the change of 3 backward travel of piston rod
In one embodiment, clamp ring 4 is connected through a screw thread with piston rod 3, according to same principle, will be rotated by screw thread
Movement switchs to move along a straight line, and then adjusts the size of groove 31, and then snap ring 51 is fixed in groove 31.That is, making piston rod 3
Pull rod 5 is driven to move synchronously when movement.
In the use of the present invention, referring to Fig.1 shown in -2, it is connect with spindle combinations by adapter flange, pull rod 5 and equipment
Chuck is fixed, and drives 3 stretching motion of piston rod by cylinder body 2, and then the stretching motion of piston rod 3 is transmitted by pull rod 5
It is clamped release movement to chuck.When clamping, under the action of hydraulic coupling, piston rod 3 rearwardly moves (i.e. such as Fig. 1 institutes
The left direction movement shown), until striking spacing collar 61, complete the pinching action of chuck.By rotary stopper circle 61, pass through
Rotary motion is switched to move along a straight line by screw thread, adjusts the relative position between spacing collar 61 and the fillet of screw 62, after realizing piston rod 3
The change to be formed is moved back, realizes that retrogressing forms variable adjustment.
The advantageous effect that the present invention obtains：
(1) the configuration of the present invention is simple, easy to adjust, precision is high.
(2) under normal operation, limit part by long-time action of hydraulic force, not will produce damaging influence.
(3) using limit method is retreated, other design method limiting devices have been prevented when something goes wrong, clamping jaw can be loose suddenly
It opens, generates serious causality loss.
The foregoing is merely a prefered embodiment of the invention, practical range not for the purpose of limiting the invention；If not departing from this
The spirit and scope of invention, modify or equivalently replace the present invention, and should all cover the protection in the claims in the present invention
In range.
