Abstract
The invention discloses an electromagnetic locking device of hydraulic cylinder cover; the electromagnetic locking device of hydraulic cylinder cover comprises a hydraulic cylinder body and a hydraulic cylinder cover; the external wall of one end around the hydraulic cylinder body and close to a mounting end of the hydraulic cylinder cover is provided with a plurality of notches; one lateral wall of each notch close to the mounting end of the hydraulic cylinder cover is provided with through holes; permanent magnets are installed inside the notches; the permanent magnets are provided with protruded ends; and the protruded ends stretch out from the through holes; the hydraulic cylinder cover is provided with a flange; the flange is provided with the same number of grooves as the notches; electromagnets are installed inside the grooves; the mounting position of each electromagnet is corresponding to one of the permanent magnets. 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 electromagnetic locking 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 electromagnetic locking 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 electromagnetic locking device, comprises cylinder body and oil cylinder cover, is provided with some notches around described cylinder body near one end outer wall of described oil cylinder cover mounting end,
Each described notch has through hole near the side sidewall of described oil cylinder cover mounting end,
In described notch, be provided with permanent magnet, described permanent magnet is provided with protruding end, and described protruding end stretches out in described through hole,
Described oil cylinder cover is provided with flange, described flange is provided with the groove that number is corresponding with described notch number, is provided with electromagnet in described groove, the corresponding described permanent magnet in position that each described electromagnet is installed.
Further, be provided with locating slot in the end of described cylinder body, the surface of described flanged surface to described cylinder body is provided with the positioning convex coordinated with described locating slot.
The present invention proposes a kind of oil cylinder cover electromagnetic locking device, by the design to electromagnet and permanent magnet, 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 electromagnetic locking device of the present invention;
Fig. 2 is the close-up schematic view of electromagnet of the present invention and permanent magnet cooperation place.
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 electromagnetic locking device as shown in Figure 1-2, comprises cylinder body 1 and oil cylinder cover 2, is provided with some notches 11 around cylinder body 1 near one end outer wall of oil cylinder cover 2 mounting end,
Each notch 11 has through hole near the side sidewall of oil cylinder cover 2 mounting end,
In notch 11, be provided with permanent magnet 3, permanent magnet 3 is provided with protruding end, and protruding end stretches out in through hole,
Oil cylinder cover 2 is provided with flange 21, flange 21 is provided with the groove that number is corresponding with notch 11 number, is provided with electromagnet 5 in groove, the corresponding permanent magnet 3 in position that each electromagnet 5 is installed.
Be provided with locating slot in the end of cylinder body 1, the surface of flange 21 towards cylinder body 1 is provided with the positioning convex 23 coordinated with locating slot.
Groove bottom land on flange 21 is provided with electromagnet 5 and installs through hole, and described electromagnet 5 one end is installed through hole from described electromagnet 5 and stretched out.
When oil cylinder cover 2 is installed, it is outside that oil cylinder cover 2 is enclosed within piston rod 4, make often pair of permanent magnet 3 corresponding with the position of electromagnet 5 according to locating slot and the cooperation of positioning convex 23 again, screw oil cylinder cover 2, open electromagnet 5 switch, because electromagnet 5 and permanent magnet 3 are that an end is stretched out from groove bottom land and notch 11 sidewall respectively and attracted each other, the shoulder of both sides, end then drives oil cylinder cover 2 and cylinder body 1, and extruding is close mutually, realizes locking function.
A kind of oil cylinder cover electromagnetic locking device of the present invention, by the design to electromagnet and permanent magnetism 3, 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.
