The overcoat of automobile sensor is the protective layer of sensor; for the protection of its transmission cable; overcoat adopts plastics to make more; it has insulation; every the effect of grade of wetting; usually all be to adopt Shooting Technique core to be realized the moulding of overcoat by injection machine or extruding machine; the present division of labor is more and more thinner; the outer mode of bringing into use finished product overcoat packing core that is with of sensor; but its effect is unsatisfactory; reason is exactly that the overcoat of finished product has certain elasticity, and under nature, its diameter shows slightly less; be difficult to core is passed, hindered the development of finished product overcoat packaging technology.
The utility model content
The purpose of this utility model is to provide a kind of sensor overcoat perforation frock of accurate cooperation, solves the problem of moment sensor finished product overcoat assembling difficulty, is convenient to the assembling of finished product overcoat, enhances productivity.
The purpose of this utility model is achieved through the following technical solutions:
A kind of sensor overcoat perforation frock of accurate cooperation, comprise upper impression and lower impressions, be provided with core groove and overcoat groove in upper impression and lower impressions, the core groove of upper impression and lower impressions constitutes complete core passage, the overcoat groove of upper impression and lower impressions constitutes complete finished product passage, and the diameter of finished product passage is greater than the diameter of core passage; Be provided with air flue in described lower impressions, air flue is communicated with the finished product passage with high-pressure air pipe on being installed in lower impressions, be provided with a through hole on described upper impression at least, and lower impressions is provided with the hole column that the through hole with upper impression is complementary.Adopt the split-type structural of upper impression and lower impressions, be provided with core groove and the overcoat groove of position correspondence in upper impression and lower impressions, wherein, upper impression is provided with two through holes, lower impressions is provided with the hole column that the through hole with upper impression is complementary, upper impression is with after lower impressions cooperates, hole column passes through hole upper impression is connected with the lower impressions secure fit, the accurate contraposition that has guaranteed upper impression and lower impressions cooperates, avoided the phenomenon of dislocation, the core groove of upper impression and lower impressions constitutes complete core passage, the overcoat groove of upper impression and lower impressions constitutes complete finished product passage, during use, the sensor core is inserted from the core passage, simultaneously sensor finished product overcoat is inserted from the finished product passage, owing in lower impressions, be provided with air flue, air flue is communicated with the finished product passage with high-pressure air pipe on being installed in lower impressions, open source of the gas, high-pressure air source is passed through pressure piping, air flue enters into core passage and finished product passage, owing in the core passage solid core is arranged, therefore, gases at high pressure are outwards carried by the cavity of finished product overcoat, because the pressure of gases at high pressure is greater than the pressure of finished product overcoat outside, gases at high pressure will have certain flexible finished product overcoat distending, its diameter be become big, at this moment, core is slowly inserted overcoat, gases at high pressure, have reduced core and have inserted the resistance that is subjected to so that gases at high pressure pass through from passing through and continue the enlarged-diameter with overcoat between overcoat and the core, reduce the packing degree of difficulty, improved the efficient of core and overcoat packing.
In described overcoat groove outer tube is installed, outer tube extends the overcoat groove.Further, in order to keep the tension force to overcoat of gases at high pressure, adopt the form that prolongs outer tube, be combined to form the form of prolongation by the outer tube of upper impression and lower impressions, increased the distance that keeps the insertion state.
Described outer tube is fixed on the anchor clamps, and anchor clamps are by being bolted on upper impression or the lower impressions.Further, for the ease of the packing of the sensor overcoat that is applicable to different model, diameter, adopt the structure of anchor clamps fixed jacket pipe, the characteristics of utilizing anchor clamps to change easily realize the replacing of different-diameter outward appearance cover, the multiple model packaging technology of coincidence senser.
The utility model compared with prior art has following advantage and beneficial effect:
The sensor overcoat perforation frock of a kind of accurate cooperation of 1 the utility model, upper impression is with after lower impressions cooperates, hole column passes through hole upper impression is connected with the lower impressions secure fit, the accurate contraposition that has guaranteed upper impression and lower impressions cooperates, avoided the phenomenon of dislocation, the sensor core is inserted from the core passage, simultaneously sensor finished product overcoat is inserted from the finished product passage, owing in lower impressions, be provided with air flue, air flue is communicated with the finished product passage with high-pressure air pipe on being installed in lower impressions, open source of the gas, high-pressure air source is passed through pressure piping, air flue enters into core passage and finished product passage, owing in the core passage solid core is arranged, therefore, gases at high pressure are outwards carried by the cavity of finished product overcoat, because the pressure of gases at high pressure is greater than the pressure of finished product overcoat outside, gases at high pressure will have certain flexible finished product overcoat distending, its diameter is become big, at this moment, core is slowly inserted overcoat, gases at high pressure are from passing through and continue the enlarged-diameter with overcoat between overcoat and the core, so that gases at high pressure pass through, reduce core and inserted the resistance that is subjected to, reduced the packing degree of difficulty, improved the efficient of core and overcoat packing;
