Snap ring is arranged in the groove, by the reciprocating movement of the piston rod, drives the reciprocating movement of the pull rod；
Position-limit mechanism is arranged in the tail portion of the cylinder body, and the position-limit mechanism adjusts the piston rod going-back position, described
Oil cylinder shell is arranged outside the cylinder body.
Further, washer is set in the groove.
Further, the position-limit mechanism includes spacing collar and the fillet of screw, and the fillet of screw is fixed with the cylinder body, institute
Spacing collar is stated to be connected through a screw thread with the fillet of screw.
Further, the clamp ring is connected through a screw thread with the piston rod.
The utility model obtain the utility model has the advantages that
(1) the utility model structure is simple, easy to adjust, and precision is high.
(2) under normal operation, limit part by long-time action of hydraulic force, will not generate 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.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram for being followed by formula and clamping stroke adjustable hollow angling cylinder of the utility model；
Fig. 2 is the enlarged drawing of A in Fig. 1.
Appended drawing reference is as follows:
1, oil cylinder shell, 2, cylinder body, 3, piston rod, 4, clamp ring, 5, pull rod, 6, position-limit mechanism, 7, main shaft, 8, switching
Flange, 31, groove, 32, washer, 51, snap ring, 61, spacing collar, 62, the fillet of screw.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.
One kind of the utility model is 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 are arranged in cylinder body 2, and with
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.During piston rod 3 is
Hollow structure, clamp ring 4 are arranged in piston rod 3, form annular groove 31 with piston rod 3, pull rod 5 is arranged in piston rod 3
In hollow structure, the side wall of pull rod 5 protrudes above setting snap ring 51, and snap ring 51 is arranged in groove 31, passes through the reciprocal shifting of piston rod 3
It is dynamic, 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 adjusts the retrogressing of piston rod 3
Position, 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, can be avoided the contact of snap ring 51 with 31 side wall of groove, 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 and cylinder body 2, which are fixed, 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.
When the utility model is used, connect by adapter flange with spindle combinations referring to Fig.1 shown in -2, pull rod 5 with set
Standby 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 passed through pull rod 5
It is transmitted to chuck and is clamped release movement.When clamping, under the action of hydraulic coupling, piston rod 3 is rearwardly moved (i.e. as schemed
Left direction shown in 1 is mobile), until striking spacing collar 61, complete the pinching action of chuck.By rotary stopper circle 61,
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, realizes piston
Bar 3 retreats the change formed, realizes that retrogressing forms variable adjustment.
The utility model obtain the utility model has the advantages that
(1) the utility model structure is simple, easy to adjust, and precision is high.
(2) under normal operation, limit part by long-time action of hydraulic force, will not generate 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 above is only the preferred embodiments of the utility model, are not used to limit the scope of the utility model；If
The spirit and scope for not departing from the utility model, are modified or replaced equivalently the utility model, should all cover in this reality
In novel scope of protection of the claims.
