Description
Technical field
The present invention relates to machine oil cleaning plug technical field, is specifically a kind of machine oil cleaning plug and processing method thereof.
Background technique
Existing machine oil cleaning plug is the device of impurity in a kind of sump for being communicated with motor oil outlet tube.As you know, automobile needs to change machine oil after the certain mileage number of traveling, ensures the lubricity of machine oil and ensures the working efficiency of motor.At present, common one magnetic machine oil cleaning plug comprises plug and magnet, and plug screws at sump sidewall, plug offers the cavity of container magnet, and magnet is fixed in cavity by mighty bond, and namely cavity inner wall is all coated with dye mighty bond.Wherein, magnet can suck the broken end of metal of tank bottoms.
Due to working long hours along with motor, the oil temperature in sump can be caused to raise, thus cause the mighty bond in the machine oil cleaning plug of this structure and machine oil increased activity, containing organic solvent toluene in mighty bond, on the one hand, temperature rising can cause mighty bond bonding failure; On the other hand, oil temperature rising can cause mighty bond and machine oil to react and cause mighty bond to lose efficacy and machine oil sex change, even causes the lubrication failure of machine oil; Meanwhile, the inefficacy along with mighty bond can cause magnet to come off from the cavity of plug, thus causes magnet to come off from plug.
Current, the processing method of machine oil cleaning plug is: placed upward by the plug offering cavity, smear mighty bond to cavity inner wall and magnet outer wall; Then, be fit into by magnet in cavity, to reach the object of fixed magnet, the magnet being and plug are integrally fixed.
There is following shortcoming in above-mentioned processing method: although above-mentioned processing method is simple, easily cause magnet and plug to come off by mighty bond connection magnet and plug, namely assemble insecure.
Summary of the invention
Technical problem to be solved by this invention is, provides the machine oil of a kind of plug and magnet firm and reliable connection to clean plug.
For solving the problems of the technologies described above, machine oil cleaning plug provided by the invention, its bag plug and magnet, plug periphery wall is provided with the outside thread for screwing with oil-tank bottom, plug upper end is provided with the cavity of accommodating magnet, the bottom of described cavity conically, is provided with pad between described magnet and cavity bottom, and plug upper end is provided with the structure for compressing magnet.
Preferred as one, described pad is resilient pad.
Preferred as one, described comprise for the structure compressing magnet the external part that is arranged on plug upper-end surface and withhold part, described part of withholding is fixedly connected with external part.
Preferred as one, the radial cross section of described external part is in the annulus closed, and the end of external part is fixedly connected with pressure ring.
Preferred as one, the radial cross section of described external part is quadrilateral spaced apart, and quadrilateral is uniformly distributed around plug axis, and the end of external part is fixedly connected with paw.
After adopting above machine oil to clean plug, the present invention compared with prior art, have the following advantages: the present invention arranges the structure for compressing magnet in plug upper-end surface, compression magnet is carried out by paw, prevent magnet from coming off from plug, achieve mechanical type fixed magnet, this comes off with regard to being avoided the magnet caused because mighty bond lost efficacy; In addition, the pad arranged between magnet and cavity bottom can be increased certain elastic force between magnet and cavity floor, there is provided when also compressing magnet to paw and necessarily cushion surplus, avoid magnet lower surface and cavity bottom generation rigid collision in paw forming process, and then produce disintegrating slag in cavity bottom.
Another technical problem to be solved by this invention is, the machine oil providing a kind of plug and magnet to be connected firmly cleans method for processing end cap, and it comprises the following steps:
A, plug is arranged on fixture, in cavity, puts into pad and magnet with this;
B, open cold header, carry out extruded by the heading of cold header to the external part of plug, fasten magnet with shaping paw;
C, antirust treatment is carried out to machine oil cleaning plug, take out finished product machine oil cleaning plug.
Preferred as one, the heading cross section in described step b is isosceles trapezoid; External part in described step b arranges chamfering, and external part chamfering is greater than the angle of inclination beta of isosceles trapezoid two waist limits relative to vertical direction relative to the inclination alpha of vertical direction.
After adopting above machine oil to clean method for processing end cap, the present invention compared with prior art, have the following advantages: being rigidly connected of magnet and plug can be realized by plug processing paw, wherein, inclination alpha is greater than angle of inclination beta can be conducive to the bending forming of plug upper-end surface external part at chamfering place, and namely heading inwall can extrude chamfering outer wall and then cause external part sidewall to bend.

Embodiment
Below in conjunction with embodiment, the present invention is described in more detail.
Embodiment:
A kind of machine oil cleaning plug, it comprises plug 1 and magnet 2, plug 1 periphery wall be provided with for sump 3 bottom the outside thread that screws, plug 1 upper end is provided with the cavity 4 of accommodating magnet 2, it is characterized in that: the bottom of described cavity 4 conically, be provided with pad 5 between bottom described magnet 2 and cavity 4, plug 1 upper end is provided with the structure for compressing magnet 2.
Described pad 5 is resilient pads.This resilient pad is made up of high carbon steel, because high carbon steel has certain elasticity.
Described comprise for the structure compressing magnet 2 external part 6 that is arranged on plug 1 upper-end surface and withhold part, described part of withholding is fixedly connected with external part 6.
