It is fully separating.Existing cable cutting device promotes to pull pin frequently with electromagnet carry out cable cutting to release spacing promotion cutter.
The advantage that electromagnet is pulled pin is smaller noise, but power of pulling pin is smaller, and cutting driving device structure is complex, it is necessary to extra power
Circuit control and the action of mechanism are provided.
The content of the invention
The invention provides a kind of cable cutting device, solve complex structure that existing cable cutting device is present and
Outside offer is needed to control and the inconvenient technical problem of driver element.
The present invention is to solve above technical problem by the following technical programs：
A kind of low cable cutting device, including cylinder, are provided with piston in cylinder, fixed in its right end face of piston
Cable knife head is provided with, piston rod is fixedly installed in the left end face of piston, be provided with the left end cap of cylinder
Piston is arranged on the outside of cylinder, pressure is socketed with the piston rod by hole, the left end of piston rod after being passed through by hole from piston
Spring, together with the left side apical grafting of piston, the left end of stage clip is with the left end cap medial surface apical grafting of cylinder one for the right-hand member of stage clip
Rise, threaded counterbore is provided with piston rod left end side, band centre bore is fixedly installed on the outside of the left end cap of cylinder
Fixed seat of pulling pin, hole of pulling pin is provided with fixed seat pulling pin, the left end of piston rod is provided with annular groove, pull pin hole with
Separation steel ball is provided between annular groove, is provided with the fixed seat of pulling pin separated on the outside of steel ball and pulled pin.
Screw rod is screwed together by hole by piston with the counterbore in piston rod left end side, and pressure is bolted with screw rod
Spring force overcomes nut, and overcome nut in stage clip elastic force is provided with protection pad and fixed seat left end lateral surface of pulling pin between,
Square cover body is provided with the lateral surface of cylinder.
The present invention carries out the design of cable cutting device using mechanical structure, main to include performing actuating mechanism and square shade
Body, is converted into the less power of pulling pin, using the mechanical parts such as steel ball, stage clip are separated by larger axial force by product itself just
Buoyancy is pulled pin to release separation steel-ball limiting, realizes that cable cuts under stage clip, the effect of cable knife head.
Brief description of the drawings
Fig. 1 is structural representation of the present invention on main view direction.
Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
A kind of low cable cutting device, including cylinder 2, are provided with piston 3 in cylinder 2, in its right end face of piston 3
Cable knife first 5 is fixedly installed, piston rod 4 is fixedly installed in the left end face of piston 3, in the left end cap of cylinder 2
On be provided with piston by hole 6, the left end of piston rod 4 is arranged on the outside of cylinder 2 after being passed through by hole 6 from piston, in piston
Stage clip 7 is socketed with bar 4, the right-hand member of stage clip 7 together with the left side apical grafting of piston 3, the left end of stage clip 7 and a left side for cylinder 2
Rubbing surface of end cover apical grafting together, is provided with threaded counterbore 8, outside the left end cap of cylinder 2 in the left end side of piston rod 4
Side is fixedly installed the fixed seat 12 of pulling pin with centre bore, hole 13 of pulling pin is provided with fixed seat 12 pulling pin, in piston rod 4
Left end is provided with annular groove 14, and steel ball 16 is separated pulling pin to be provided between hole 13 and annular groove 14, is separating the outside of steel ball 16
Fixed seat 12 of pulling pin on be provided with and pull pin 15.
Screw rod 9 is screwed together by hole 6 by piston with the counterbore 8 in the left end side of piston rod 4, the spiral shell on screw rod 9
It is connected to stage clip elastic force and overcomes nut 10, overcome nut 10 in stage clip elastic force is provided with and the left end lateral surface of fixed seat 12 of pulling pin between
Protection pad 11, is provided with square cover body 1 on the lateral surface of cylinder 2.
Installation process of the invention is as follows：Piston rod 4 and piston 3 are fastened with screw first, by cable knife first 5 with
Piston 3 is fastened with screw；The end of square cover body 1 is fixed on the M4 screws fixed seat 12 that will pull pin；Load stage clip 7 in cylinder 2,
Screw rod 9 is screwed together by hole 6 by piston with the counterbore 8 in the left end side of piston rod 4；Tighten stage clip elastic force and overcome nut
10 to annular groove 14 is concordant with the circular hole of fixed seat 12 of pulling pin, and installs and separates steel ball 16, and insertion pulls pin 15；Fixed cable is installed, most
After dismantle screw rod 9, stage clip elastic force overcome nut 10, protection pad 11, realize the assembling of whole cable cutting device.Cable cuts
In front deck end, pull pin 15 is connected with sail body for device integral installation, after front deck is separated with sail body, front deck positive buoyancy
To be pulled pin 15 solution systems, realize the process of cutting cable.
If the present apparatus is put into water, its action process is as follows：Under positive buoyancy effect, will pull pin 15 releases, releases and divides
From the spacing of steel ball, under the pretightning force effect of stage clip 7, promote cable knife first 5 quickly to move, realize that cable cuts.This
Invention can be separated by sail body and carry out solution system of pulling pin, and release stage clip limitation, promote cutter head to carry out cable cutting.The device is pulled out
Pin power comes from the positive buoyancy after front deck is separated, and can produce larger power of pulling pin；Stage clip pretightning force is carried out by steel ball structure
Decompose, reduce power of pulling pin；Control in terms of in the absence of circuit signal, without considering power source in terms of limitation；Simple structure,
Sail body can be arranged on out of my cabin, it is small to the requirement of the conditions such as temperature, humidity with good environmental suitability.
