Abstract
The utility model discloses a rotating speed sensor case, which comprises a body and an end cover, wherein the end cover is made of brass, the body is made of Q235 steel, a through hole is arranged in the middle of the body, steps are arranged around a through hole arranged at the lower end of the body, and the upper end of the end cover is embedded and connected with the steps arranged at the lower end of the body. The end cover is brazed and connected with the case, and the end cover can also be riveted with the case. The original case body material of copper is changed into iron, a through hole is arranged at the bottom of the case, a step is made, then, the copper end cover is processed, and the two parts are brazed and formed or riveted. The price of the iron is much lower than that of the copper, the copper end cover arranged at the bottom end is punched by a punching tool mold, the two parts are brazed or riveted, the performance is not influenced, the structure is simple, the implementation is convenient, the requirement in the production is reached, and the cost can also be reduced.
Description
Technical field
The utility model relates to a kind of speed probe, especially the shell of speed probe.
Background technology
Speed probe is to be matched in the rotating speed that motor car engine is used for detection of engine.The principle of work of speed probe is the top that sensor is vertically mounted on engine gear, the iron and steel magnetic conductivity is strong and air reluctance is big, when the gear revolution of engine moves a tooth, cause the Hall element surrounding magnetic field to change, the Hall element self character is exactly that the ambient magnetic flux amount can produce a pulse signal when changing, pulse signal is transferred to car running computer after handling, and then demonstrates the rotating speed of engine through amplification, shaping.Based on this principle of work, sensor outer housing must be non-magnetic metal or nonmetallic materials, not so can block the magnetic line of force, because the brass (H62) of the whole uses of the sheathing material of producing at present, but along with the price of copper on the market is constantly soaring, under the situation that the single price of sensor descends year by year, cost improves constantly.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of rational in infrastructure, the speed probe shell that the cost of material is low.
The technical solution of the utility model is:
A kind of shell of speed probe comprises body, also comprises end cap, the material of end cap is a brass, and the material of described body is the Q235 steel, and the centre of body is a through hole, be provided with step around the lower end through hole of body, the upper end of end cap is inlayed with the step of body lower end and is connected.
Described end cap is connected with the shell soldering.
Described end cap also can with outer shell rivething.
Beneficial effect: the utility model changes original outer cover body material copper into iron, but iron is good permeability magnetic material, if whole casing is all used iron, internal magnetic field just all is enclosed in the shell of iron, and the magnetic line of force can not see through shell and arrive the gear top, and transmitting gear just can not induce signal, so the hole is punched in the bottom at shell, do a step, process the end cap of a copper then, two parts are lead welding and shaping or be riveted together again.The copper end cap of bottom adopts the punching machine mold punching press to the price of iron in copper at the end far away, two part soldering or riveted joints, last whole electric zinc electroplating with iridescent yellow chromate conversion coating.Whole parts outward appearance looks similar to the shell of simple brass processing, and performance is not affected, and the processing of iron shell, towards end cap, soldering or riveted joint, electroplate cost that all technologies add up also adds passivation technology far below the copper shell cost.Simple in structure, it is convenient to implement, and can reach needs in the production and can reduce cost.
Description of drawings
Fig. 1 is the speed probe structural representation;
Fig. 2 is a speed probe shell mechanism synoptic diagram of the prior art;
Fig. 3 is a speed probe shell mechanism synoptic diagram of the present utility model.
Among the figure: 1-body, 2-printed board, 3-Hall element support, 4-magnet steel, 5-Hall element, 6-end cap, 7-gear, 8-through hole, 9-step.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of shell of speed probe comprises body 1, also comprises end cap 6, the material of end cap 6 is a brass, and the material of body 1 is the Q235 steel, and the centre of body 1 is a through hole 8, be provided with step 9 around the lower end through hole 8 of body 1, the upper end of end cap 6 is inlayed with the step 9 of body 1 lower end and is connected.
Existing speed probe principle is that Hall element 5 and magnet steel 4 are packed in the Hall element support 3, again with printed board 2 welding, pack in the lump in the body 1, the magnetic line of force axially passes Hall element 5, end cap 6 arrives gear 7, body 1 is an integral body with end cap 6 before improving, material is brass (H62) entirely, this moment gear 7 at the bottom of turning to tooth when the tooth top, pass the magnetic force number of lines difference of Hall element 5, the rate of change difference of magnetic flux, Hall element 5 induce signal and export through printed board 2 processing of circuit.
After improving, body 1 usefulness material is decided to be the Q235 steel, and Q235 rod iron material is processed into the shape of body 1, intermediate throughholes, processing step around via bottoms, copper sheet is washed into end cap 6 sizes on punching machine mold, the step dimension of the step dimension of end cap 6 and body 1 is coincide again, and two parts are put together, put into the silver band in the slit of end cap 6 and body 1, integral body is put into solderer, and high temperature dissolves the silver band, and end cap 6 and body 1 are welded together.
Also can adopt end cap 6 is placed in the body 1, body 1 usefulness hydropress is turned over the riveting moulding, be riveted together.
