Abstract
The invention discloses a cable cutting device. The problems that an existing cable cutting device is complex in structure, a control and driving unit needs to be externally provided, and inconvenience is caused are solved. The cable cutting device comprises a piston (3) arranged in a barrel (2). A cable cutting tool bit (5) is fixedly arranged on the right end face of the piston (3). A piston rod (4) is fixedly arranged on the left end face of the piston (3) and sleeved with a compression spring (7). A pull pin (15) is released, limiting of a separation steel ball is eliminated, the cable cutting tool bit (5) is pushed to fast move under the action of the pretightening force of the compression spring (7), and cable cutting is achieved. The pretightening force of the compression spring is decomposed through a steel ball structure, and pull pin force is reduced. Control over circuit signals does not exist, and the limit of a power source does not need to be considered.
Description
Technical field
The present invention relates to a kind of mechanical severing device, particularly a kind of mechanical severing device cutting off cable.
Background technology
Submarine navigation device, when laying product, relates to the separation completely being cut off to realize product after signal cable completes function.Existing cable cutting device often adopts electromagnet to promote to pull pin to remove spacing promotion cutter and carry out cable cutting.The advantage that electromagnet is pulled pin is that noise is less, but power of pulling pin is less, and cutting driving device structure is comparatively complicated, needs extra power to provide the action of control circui and mechanism.
Summary of the invention
The invention provides a kind of cable cutting device, solve the complex structure that existing cable cutting device exists and the technical problem needing outside to provide control and driver element inconvenience.
The present invention solves above technical problem by the following technical programs:
A kind of low cable cutting device, comprise cylindrical shell, piston is provided with in cylindrical shell, the its right end face of piston is fixedly installed cable knife head, the left end face of piston is fixedly installed piston rod, the left end cap of cylindrical shell is provided with piston passing hole, the left end of piston rod is from the outside being arranged on cylindrical shell after piston passing hole is passed, be socketed with stage clip on the piston rod, the right-hand member of stage clip is together with the left side apical grafting of piston, the left end of stage clip is together with the left end cap medial surface apical grafting of cylindrical shell, piston rod left end side is provided with threaded counterbore, the holder of pulling pin of band centre bore is fixedly installed outside the left end cap of cylindrical shell, be provided with hole of pulling pin pulling pin on holder, the left end of piston rod is provided with cannelure, be separated steel ball pulling pin to be provided with between hole with cannelure, holder of pulling pin outside separation steel ball is provided with and pulls pin.
Screw rod is screwed together by the counterbore 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 between holder left end lateral surface and be provided with protection pad, the lateral surface of cylindrical shell is provided with square cover body.
The present invention adopts frame for movement to carry out the design of cable cutting device, mainly comprise perform an action mechanism and square cover body, utilize mechanical parts such as separation steel ball, stage clip etc. that larger axial force is converted into less power of pulling pin, rely on the positive buoyancy of product self to extract to pull pin to remove separation steel-ball limiting, under stage clip, the effect of cable knife head, realize cable cutting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention in main apparent direction.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of low cable cutting device, comprise cylindrical shell 2, piston 3 is provided with in cylindrical shell 2, the its right end face of piston 3 is fixedly installed cable knife head 5, the left end face of piston 3 is fixedly installed piston rod 4, the left end cap of cylindrical shell 2 is provided with piston passing hole 6, the left end of piston rod 4 is from the outside being arranged on cylindrical shell 2 after piston passing hole 6 is passed, piston rod 4 is socketed with stage clip 7, the right-hand member of stage clip 7 is together with the left side apical grafting of piston 3, the left end of stage clip 7 is together with the left end cap medial surface apical grafting of cylindrical shell 2, piston rod 4 left end side is provided with threaded counterbore 8, the holder 12 of pulling pin of band centre bore is fixedly installed outside the left end cap of cylindrical shell 2, be provided with hole 13 of pulling pin pulling pin on holder 12, the left end of piston rod 4 is provided with cannelure 14, be separated steel ball 16 pulling pin to be provided with between hole 13 with cannelure 14, holder 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 counterbore 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 to be provided with between holder 12 left end lateral surface and protect pad 11, the lateral surface of cylindrical shell 2 is provided with square cover body 1.
Installation process of the present invention is as follows: first by piston rod 4 and piston 3 screw fastening, by cable knife head 5 and piston 3 screw fastening; Square cover body 1 end is fixed on M4 screw holder 12 of pulling pin; Load stage clip 7 in cylindrical shell 2, screw rod 9 is screwed together by piston passing hole 6 and the counterbore 8 in piston rod 4 left end side; Tightening stage clip elastic force, to overcome nut 10 to cannelure 14 concordant with holder 12 circular hole of pulling pin, and installs and be separated steel ball 16, inserts and pull pin 15; Install attached cable, screw rod 9 of finally dismantling, stage clip elastic force overcome nut 10, protection pad 11, realize the assembling of whole cable cutting device.Cable cutting device integral 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, realize the process of cutting cable.
If this device is put into water, its course of action is as follows: under positive buoyancy effect, 15 releases of pulling pin, and removes and is separated the spacing of steel ball, under the pretightning force effect of stage clip 7, promotes cable knife head 5 rapid movement, realizes cable cutting.The present invention can rely on sail body separation to carry out the system of separating of pulling pin, and removes stage clip restriction, and promotion cutter head carries out cable cutting.The power of pulling pin of this device come from front deck be separated after positive buoyancy, larger power of pulling pin can be produced; By steel ball structure, stage clip pretightning force is decomposed, reduce the power of pulling pin; There is not the control of circuit signal aspect, without the need to considering the restriction of power source aspect; Structure is simple, can be arranged on sail body out of my cabin, have good environmental suitability, little to the conditional request such as temperature, humidity.
