Abstract
The invention discloses a tensioning device of hydraulic cylinder cover; the tensioning device of hydraulic cylinder cover comprises a hydraulic cylinder body, a hydraulic cylinder cover, a tensioning spring, and a tensioning slide block; the inner lateral wall of the hydraulic cylinder body is provided with a square groove; the tensioning spring is mounted at the bottom of the groove; the tensioning slide block is mounted inside the groove and is slidably matched with the groove and further fixedly connected with the tensioning spring; when the tensioning spring is completely compressed; the surface of the tensioning slide block facing to the interior of the hydraulic cylinder body is a threaded surface; the threaded surface stretches out of the inner surface of the hydraulic cylinder body; the threaded surface is provided with a partial thread; the partial thread is connected with the bilateral threads on the hydraulic cylinder body to form an integral thread. The electromagnetic locking device of hydraulic cylinder cover is able to effectively lock the hydraulic cylinder with the hydraulic cylinder cover, and the dismount thereof is convenient, thus effectively ensuring the safe production and the normal running.
Description
Technical field
The present invention relates to a kind of locking device technical field, especially a kind of oil cylinder cover tension device.
Background technique
Oil cylinder cover is normally threaded with the connection of oil cylinder, and internal thread established by oil cylinder, and oil cylinder cover establishes outside thread, under the effect of pressure oil, the situation that being threaded between cylinder barrel with cylinder cap likely occurs to loosen and cause cylinder cap to come off, therefore, is necessary to take certain locking measure.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of oil cylinder cover tension device, can effectively oil cylinder and oil cylinder cover be locked, and easy disassembly, effectively ensure that the safety of production and normal operation.
In order to realize foregoing invention object, the invention provides following technological scheme:
A kind of oil cylinder cover tension device, comprises cylinder body, oil cylinder cover, tensioner spring and tensioning slide block,
Described cylinder body madial wall has square groove, and described tensioner spring fitting is at the bottom land of described groove, and described tensioning slide block is arranged on described inside grooves and is slidably matched with described groove and is fixedly connected with tensioner spring,
When described tensioner spring is fully compressed, described tensioning slider surface is thread surface to the surface in described cylinder body, described thread surface stretches out described inner surface of cylinder block, described thread surface is provided with partial screw threads, and described partial screw threads forms complete screw thread with being threaded on cylinder body described in its both sides.
Further, described thread surface is arc, and its radius of curvature is identical at the cross sectional radius of described groove location with described cylinder body.
Further, be oblique excessive face between the side surface stretching into direction at described thread surface and described tensioning slider surface to piston rod.
A kind of oil cylinder cover tension device of the present invention, by the design to tensioner spring and tensioning slide block structure, effectively by oil cylinder and oil cylinder cover locking, and can facilitate oil cylinder cover dismounting, effectively ensure that the safety of production and normal operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of oil cylinder cover tension device of the present invention;
Fig. 2 is the schematic diagram of tensioning slide block of the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of oil cylinder cover tension device as shown in Figure 1-2, comprises cylinder body 1, oil cylinder cover 2, tensioner spring 5 and tensioning slide block 4,
Cylinder body 1 madial wall has square groove 6, and tensioner spring 5 is arranged on the bottom land of groove 6, and tensioning slide block 4 is arranged on groove 6 inside and is slidably matched with groove 6 and is fixedly connected with tensioner spring 5,
When tensioner spring 5 is fully compressed, tensioning slide block 4 is thread surface 42 towards the surface in cylinder body 1, thread surface 42 stretches out cylinder body 1 internal surface, and thread surface 42 is provided with partial screw threads, and partial screw threads forms complete screw thread with being threaded on its both sides cylinder body 1.
Thread surface 42 is arc, and its radius of curvature is identical at the cross sectional radius of groove 6 position with cylinder body 1.
Be oblique excessive face 41 between the side surface stretching into direction at thread surface 42 and tensioning slide block 4 towards piston rod 3, in order to oil cylinder cover 2 stretches in cylinder body 1 more smoothly, tiltedly excessively face 41 be also provided with partial threads near the position of thread surface 42.
The end position stretched in cylinder body 1 after groove 6 position installs with oil cylinder cover 2 is corresponding,
Groove 6, tensioner spring 5 and tensioning slide block 4 can arrange multiple, are uniformly distributed around cylinder body 1 inwall.
During use, the external screw-thread of oil cylinder cover 2 coordinates with the internal whorl of cylinder body 1, oil cylinder cover 2 can extrude the tiltedly excessive face 41 on progress slide block to the process that cylinder body 1 inside screws in, the progress slide block originally stretched out in groove 6 is made to be squeezed in groove 6, due to when tensioner spring 5 is extruded completely, thread surface 42 so stretches out groove 6, so the extruding to oil cylinder cover 2 can be realized, thread surface 42 stretch out groove 6 amount can accurate adjustment to very little, combine the screw thread on oblique excessively face 41 again, just oil cylinder cover 2 can be screwed in cylinder body 1.
A kind of oil cylinder cover tension device of the present invention, by the design to tensioner spring and tensioning slide block structure, effectively by oil cylinder and oil cylinder cover locking, and can facilitate oil cylinder cover dismounting, effectively ensure that the safety of production and normal operation.
