Abstract
Present invention discloses a kind of processing technologys of automobile oil level sensor bushing, specifically include step: material selection, stamping process, grind both-end surface treatment, polishing treatment and electroplating processes.The processing technology for a kind of automobile oil level sensor bushing that the present invention discloses, it is only necessary to which four procedures can complete the processing to automobile oil level sensor bushing, and production cost is greatly saved and improves production efficiency.
Description
Technical field
The present invention relates to a kind of processing technology more particularly to a kind of processing technologys of automobile oil level sensor bushing.
Background technique
Fuel level sensor is to enter the variation for causing capacitance between sensor housing and induction electrode after container using oil,
And this change transitions is detected to the part of oily in container position (height) for curent change, it needs to cooperate lining during installation
Set installation, in order to not influence the use of fuel level sensor, the surface smoothness of bushing is more demanding, and existing bushing is processed
It for the flatness at both ends in journey, is constantly merged by grinding machine, measurement adjusts to realize, shows precision is higher and higher
Generation, traditional way are no longer satisfied use demand.
Summary of the invention
It is an object of the invention to overcome the deficiencies of existing technologies, a kind of processing work of automobile oil level sensor bushing is provided
Skill.
To achieve the above object, the following technical solutions are proposed by the present invention:
A kind of processing technology of automobile oil level sensor bushing, specifically comprises the following steps:
A. DC04-C440 cold-rolled strip, 17 ± 0.1mm of width of steel band, 1.65 ± 0.02mm of thickness material selection: are selected；
B. cold-rolled strip in step a is packed into mold, is automatically fed into Full-automatic combination punching machine that carry out punching press to it in blocks,
Just one-step forming is carried out then into bending unit, full circle processing finally is carried out to product again；
C. the product handled well in step b is sent into Horizontal paralled surface grinding machine and carries out face grinding processing, pass through full-automatic feeding charging tray
Machine carries out feeding processing, and product is aligned to above mill one by one, is ground simultaneously by both sides grinding wheel, two end faces of product are put down
Row degree reaches within 0.05mm, within flatness 0.05mm；
D. the product completed in step c is sent into duplex polishing machine and carries out polishing deburring processing, then carrying out zinc-plated place
Reason, Zinc Coating Thickness require 20-30um.
Compared with prior art, the processing technology for a kind of automobile oil level sensor bushing that the present invention discloses, it is only necessary to four
Procedure can complete the processing to automobile oil level sensor bushing, and production cost is greatly saved and improves production effect
Rate uses Double End grinding technics, and processing back bush flatness precision is high, and efficiency greatly improves.
Specific embodiment
The technical solution to the embodiment of the present invention is subjected to clear, complete description below.
The processing technology of disclosed automobile oil level sensor bushing, specifically comprises the following steps:
A. DC04-C440 cold-rolled strip, 17 ± 0.1mm of width of steel band, 1.65 ± 0.02mm of thickness material selection: are selected；
B. cold-rolled strip in step a is packed into mold, is automatically fed into Full-automatic combination punching machine that carry out punching press to it in blocks,
Just one-step forming is carried out then into bending unit, full circle processing finally is carried out to product again；
C. the product handled well in step b is sent into Horizontal paralled surface grinding machine and carries out face grinding processing, pass through full-automatic feeding charging tray
Machine carries out feeding processing, and product is aligned to above mill one by one, is ground simultaneously by both sides grinding wheel, two end faces of product are put down
Row degree reaches within 0.05mm, within flatness 0.05mm.
D. the product completed in step c is sent into duplex polishing machine and carries out polishing deburring processing, then plated
Zinc processing, Zinc Coating Thickness require 20-30um.
Technology contents and technical characteristic of the invention have revealed that as above, however those skilled in the art still may base
Make various replacements and modification without departing substantially from spirit of that invention, therefore, the scope of the present invention in teachings of the present invention and announcement
It should be not limited to the revealed content of embodiment, and should include various without departing substantially from replacement and modification of the invention, and be this patent Shen
Please claim covered.
