Abstract
The invention discloses an external perforating method for a sensor. An upper profile cavity and a lower profile cavity are included. The upper profile cavity and the lower profile cavity are each provided with a core material groove and an outer sleeve groove. The core material grooves of the upper profile cavity and the lower profile cavity form a complete core material passage. The outer sleeve grooves of the upper profile cavity and the lower profile cavity form a complete finished product passage. The diameter of the finished product passage is larger than that of the core material passage. An air passage is arranged in the lower profile cavity and enables the finished product passage to be communicated with a high-pressure air pipe installed on the lower profile cavity. A core material is slowly inserted into an outer sleeve, high-pressure air passes through the space between the outer sleeve and the core material, and the diameter of the outer sleeve continues to be increased so that the high-pressure air can pass conveniently. The resistance when the core material is inserted is reduced, the packaging difficulty is lowered, and the packaging efficiency of the core material and the outer sleeve is improved.
Description
Technical field
The present invention relates to a kind of aid in sensor manufacturing, specifically refer to a kind of external perforation method of sensor.
Background technology
Automobile wheel speed sensor is primarily of compositions such as inductive head, wire harness and annexes.The effect of inductive head is exactly coordinate with the target gear be contained on automobile chassis, the rotating speed of measured automobiles wheel, is made up of the part such as coil, magnetic pole.On this basis, ensure normal operation of sensor, sensor also must be enable reasonably to be installed on automobile chassis, and its mounting means has a lot.Existing normally used have a kind of wheel speed sensors to be the steel shell and the part that rely on inductive head outside, and namely resilient bushing coordinates, and loads in the corresponding mounting hole of chassis.During design sensor, need by magnet steel, magnetizer combination in centre, magnetic conductor is an iron core, and coil, around magnet steel and iron core, forms magnetic conduction coil.The change of the coil-induced surrounding magnetic field of magnetic conduction, produce the signal of telecommunication, this signal of telecommunication outputs to external device (ED) by capillary.The supporting mass of magnet steel, iron core, coil is called skeleton.Existing skeleton is split type skeleton, first needs injection moulding one frame body, reinstalls iron core, magnet steel, finally reinstall stopper, forms skeleton; The technical process forming sensing head is as follows: 1, processing parts: frame body, magnetic conductor, magnet steel, capillary, stopper, coil, cotton thread; 2, assembling process: iron core gluing loading frame body-coiling-twine cotton thread-dress magnet steel-stopper gluing assembling-coil the end of a thread line tail to be wound on capillary.
The overcoat of automobile sensor is the protective layer of sensor, for the protection of its transmission cable, overcoat is adopted made of plastic more, it has insulation, effect is waited every wet, usually be all adopt Shooting Technique that core is realized the shaping of overcoat by injection machine or extruding machine, the current division of labor is more and more thinner, the mode of core packed by the finished product overcoat of bringing into use that the overcoat of sensor has, but its effect is unsatisfactory, reason is exactly that the overcoat of finished product has certain elasticity, in its natural state, its diameter shows slightly less, core is difficult to pass, hinder the development of finished product overcoat packaging technology.
Summary of the invention
The object of the present invention is to provide a kind of external perforation method of sensor, solve the problem of moment sensor finished product overcoat assembling difficulty, be convenient to the assembling of finished product overcoat, enhance productivity.
Object of the present invention is achieved through the following technical solutions:
A kind of external perforation method of sensor, comprise upper impression and lower impressions, upper impression and lower impressions are provided with core groove and overcoat groove, the core groove of upper impression and lower impressions forms complete core passage, the overcoat groove of upper impression and lower impressions forms complete product channel, and the diameter of product channel is greater than the diameter of core passage; In described lower impressions, be provided with air flue, product channel is communicated with the high-pressure air pipe be arranged in lower impressions by air flue.Adopt the split-type structural of upper impression and lower impressions, upper impression and lower impressions are provided with core groove corresponding to position and overcoat groove, wherein, after upper impression and lower impressions are connected, the core groove of upper impression and lower impressions forms complete core passage, the overcoat groove of upper impression and lower impressions forms complete product channel, during use, sensor core is inserted from core passage, sensor finished product overcoat is inserted from product channel simultaneously, owing to being provided with air flue in lower impressions, product channel is communicated with the high-pressure air pipe be arranged in lower impressions by air flue, open source of the gas, high-pressure air source passes through pressure piping, air flue enters into core passage and product channel, owing to having solid core in core passage, therefore, gases at high pressure are outwards carried by the cavity of finished product overcoat, pressure due to 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 large, now, core is slowly inserted overcoat, gases at high pressure are from passing through between overcoat and core and continuing the enlarged-diameter of overcoat, so that gases at high pressure pass through, reduce core and insert the resistance be subject to, reduce packaging degree of difficulty, improve the efficiency that core and overcoat are packed.
In described overcoat groove, be provided with outer tube, outer tube extends overcoat groove.Further, in order to keep the tension force to overcoat of gases at high pressure, adopting and extending the form of outer tube, be combined to form the form of prolongation by the outer tube of upper impression and lower impressions, add the distance keeping insert state.
Described outer tube is fixed on fixture, and fixture is bolted in upper impression or lower impressions.Further, for the ease of being applicable to the packaging of sensor overcoat of different model, diameter, adopting the structure of fixture fixed jacket pipe, utilizing fixture to hold easily changeable feature, realize the replacing of different-diameter outward appearance cover, the Multiple Type packaging technology of coincidence senser.
The present invention compared with prior art, has following advantage and beneficial effect:
The external perforation method of a kind of sensor of 1 the present invention, sensor core is inserted from core passage, sensor finished product overcoat is inserted from product channel simultaneously, owing to being provided with air flue in lower impressions, product channel is communicated with the high-pressure air pipe be arranged in lower impressions by air flue, open source of the gas, high-pressure air source passes through pressure piping, air flue enters into core passage and product channel, owing to having solid core in core passage, therefore, gases at high pressure are outwards carried by the cavity of finished product overcoat, pressure due to 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 large, now, core is slowly inserted overcoat, gases at high pressure are from passing through between overcoat and core and continuing the enlarged-diameter of overcoat, so that gases at high pressure pass through, reduce core and insert the resistance be subject to, reduce packaging degree of difficulty, improve the efficiency that core and overcoat are packed,
The external perforation method of a kind of sensor of 2 the present invention, adopts the structure of fixture fixed jacket pipe, utilizes fixture to hold easily changeable feature, realizes the replacing of different-diameter outward appearance cover, the Multiple Type packaging technology of coincidence senser.
