Description
Technical field
The present invention relates to brake disc key characteristic detection devices, become more particularly to a kind of brake disc braking surface radial thickness
The device of change amount, circumferential thickness variable quantity and the bounce of upper and lower braking surface axial circular while detection.
Background technology
Brake disc is the key components and parts in automotive brake.Disc thickness variable quantity is to judge brake disc function, peace
The key property of dress, it is overproof to lead to that contact is unevenly distributed and brake force equivalent redius changes.It makes simultaneously
The thickness change of Moving plate it is overproof also can forced brake wheel cylinder piston axial movement, lead to the fluctuation of brake pressure.Work as brake disc
Amounts of thickness variation is more than certain numerical value, vehicle or its component will be caused to shake in braking.Braking surface is axial up and down for brake disc
Circle bounce be equally judge brake disc function, installation key property, can be gradually decreased under long-term immobilization state, but it makes
Brake disc thickness difference gradually increases, and braking shake is finally also resulted in more than certain value.So needing to braking
The bounce of braking surface axial circular is monitored up and down for disc thickness variable quantity (thickness is poor) and brake disc.
Currently, it is to brake that test disc thickness variable quantity, which uses three coordinates or thickness micrometer, concrete operation method,
(can be by 15 ° or 30 ° of deciles) be done if uniformly being taken on the same circumferencial direction of disk disk, thickness value is measured respectively, then asks most
The difference of big value and minimum value is circumferential thickness variable quantity (circumferential thickness is poor)；On different circumferencial directions, along Radius side
If doing (can be by 5mm deciles) to uniformly taking, thickness value is measured respectively, and then the difference of maximizing and minimum value is radial thick
Spend variable quantity (radial thickness is poor).
It is to be horizontally arranged brake disc to test the braking surface method that axial circular is beated up and down, with brake disc mounting surface in
Heart hole positions, and limits moved along the moving of Z-direction, the rotation of X, Y direction and X, Y direction respectively, with a magnetic force
Dial gauge withstands braking surface, rotates braking surface axial circular bounce on braking looping test by hand, then adjusts magnetic force dial gauge again
Lower braking surface axial circular bounce is tested in position to lower section.Two magnetic force dial gauges can also be used, adjust separately good position, simultaneously
The axial circular bounce of two braking surfaces above and below test.
It is either three coordinates or thickness micrometer using the shortcomings that three coordinates or thickness miking thickness difference, all
It needs to acquire many points and statistic record, then calculate again, need to spend many time of measuring.The point of acquisition is simultaneously
Breakpoint can not reflect that the thickness value in whole circumference, accuracy are relatively low.Secondly the when of measuring is taken also to deposit in acquisition
It is possible to not on the same circumference in the point of larger site error, acquisition, mistake is increased to detection circumferential thickness variable quantity
Difference.
When beating using magnetic force centimeter check braking surface axial circular, need to adjust magnetic force dial gauge at each test
Position, and detect up and down braking surface it is same diametrically axial circular bounce when, using magnetic force dial gauge need spend it is longer when
Between adjust the position of dial gauge up and down, and by external force, the joint of magnetic force dial gauge is easily subjected to displacement or pine
It is dynamic, a degree of influence is caused on the accuracy of detection.
Invention content
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of simple in structure, debugging side
