Description
Technical field
The present invention relates to a kind of cut mechanically device, in particular to a kind of cut mechanically device cutting off cable.
Background technology
Submarine navigation device is when laying product, it relates to cut off the separation completely realizing product after completing function to signal cable. Existing cable cutting device often adopts electro-magnet to promote and pulls pin to release spacing promotion cutter and carry out cable cutting. The advantage that electro-magnet is pulled pin is that noise is less, but power of pulling pin is less, and cutting driving device structure is comparatively complicated, it is necessary to extra power provides the action of control circui and mechanism.
Summary of the invention
The present invention provides a kind of cable cutting device, solves the complex structure of existing cable cutting device existence and needs outside to provide the technical problem controlling and driving unit inconvenience.
The present invention solves above technical problem by the following technical programs:
A kind of low cable cutting device, comprise cylinder, cylinder is provided with piston, the its right end face of piston is fixedly installed cable cutter head, the left end face of piston is fixedly installed piston rod, the left end cap of cylinder is provided with piston passing hole, the left end of piston rod is arranged on the outside of cylinder from piston passing hole after passing, it is socketed with stage clip on the piston rod, the right-hand member of stage clip and the top, left side of piston are connected together, in the left end of stage clip and the left end cap of cylinder, top, side is connected together, piston rod left end side is provided with threaded heavy hole, the permanent seat of pulling pin of band centre hole it is fixedly installed outside the left end cap of cylinder, permanent seat is provided with hole of pulling pin pulling pin, left end at piston rod is provided with ring groove, it is separated steel ball pulling pin to be provided with between hole with ring groove, permanent seat of pulling pin outside separation steel ball is provided with and pulls pin.
Screw rod is screwed together by the heavy hole in piston passing hole and piston rod left end side; screw rod is bolted with stage clip elastic force and overcomes nut; overcome nut at stage clip elastic force and pull pin and be provided with protection pad between permanent seat left end outer side, the outer side of cylinder is provided with square cover body.
The present invention adopts physical construction to carry out the design of cable cutting device, mainly comprise perform an action mechanism and square cover body, utilize the separation mechanical parts such as steel ball, stage clip that bigger axial force is converted into less power of pulling pin, relying on the positive buoyancy of product self to extract, to pull pin to release separation steel ball spacing, realizes cable cutting under stage clip, cable cutter head effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention in main apparent direction.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of low cable cutting device, comprise cylinder 2, cylinder 2 is provided with piston 3, the its right end face of piston 3 is fixedly installed cable cutter head 5, the left end face of piston 3 is fixedly installed piston rod 4, the left end cap of cylinder 2 is provided with piston passing hole 6, the left end of piston rod 4 is arranged on the outside of cylinder 2 from piston passing hole 6 after passing, piston rod 4 is socketed with stage clip 7, the right-hand member of stage clip 7 and the top, left side of piston 3 are connected together, in the left end of stage clip 7 and the left end cap of cylinder 2, top, side is connected together, piston rod 4 left end side is provided with threaded heavy hole 8, the permanent seat 12 of pulling pin of band centre hole it is fixedly installed outside the left end cap of cylinder 2, permanent seat 12 is provided with hole 13 of pulling pin pulling pin, left end at piston rod 4 is provided with ring groove 14, it is separated steel ball 16 pulling pin to be provided with between hole 13 with ring groove 14, permanent seat 12 of pulling pin outside separation steel ball 16 is provided with and pulls pin 15.
Screw rod 9 is screwed together by piston passing hole 6 and the heavy hole 8 in piston rod 4 left end side; screw rod 9 is bolted with stage clip elastic force and overcomes nut 10; overcome nut 10 at stage clip elastic force and pull pin and between permanent seat 12 left end outer side, be provided with protection pad 11, the outer side of cylinder 2 is provided with square cover body 1.
The installation process of the present invention is as follows: first by piston rod 4 and piston 3 screw fastening, by cable cutter head 5 and piston 3 screw fastening; It is fixed on square cover body 1 end with M4 screw permanent seat 12 of pulling pin; Loading stage clip 7 in cylinder 2, screw rod 9 is screwed together by piston passing hole 6 and the heavy hole 8 in piston rod 4 left end side; Tightening stage clip elastic force, to overcome nut 10 to ring groove 14 concordant with permanent seat 12 circular hole of pulling pin, and installs separation steel ball 16, and insertion pulls pin 15; Installing attached cable, screw rod 9 of finally dismantling, stage clip elastic force overcome nut 10, protection pad 11, it is achieved the assembling of whole cable cutting device. Cable cutting device complete installation is in front deck end, and pulling pin 15 is connected with sail body place, and after front deck is separated with sail body, front deck positive buoyancy will be pulled pin 15 solution systems, it is achieved the process of cutting cable.
If this device is put into water, its action process is as follows: under positive buoyancy effect, 15 releases of pulling pin, and releases the spacing of separation steel ball, under the preliminary tension effect of stage clip 7, promotes cable cutter head 5 rapid movement, it is achieved cable cuts. The present invention can rely on sail body separation to carry out the system of separating of pulling pin, and releases stage clip restriction, promotes cutter head to carry out cable cutting. The power of pulling pin of this device comes from the positive buoyancy after front deck separation, it is possible to produce bigger power of pulling pin; By steel ball structure, stage clip preliminary tension is decomposed, reduce the power of pulling pin; There is not the control of circuit signal aspect, it is not necessary to consider the restriction of propulsion source aspect; Structure is simple, it is possible to be arranged on sail body out of my cabin, has good environmental compatibility, requires little to the condition such as temperature, humidity.
