Description
Technical field
The present invention relates to the technical field of detection means, it is especially a kind of Work piece sealing groove being applied to and there is seal groove
The detection means of groove depth.
Background technology
In machinery industry, numerous parts are provided with the seal groove for installing sealing ring, such as front cover for vehicle, such as accompanying drawing
Shown in 1, two seal grooves, respectively seal groove I 2 and seal groove II 3 are had on the end face of front cover for vehicle, this two sealings
Groove is to be processed by special groove knife in processing, face 1 on the basis of the end face of front cover for vehicle, the groove of this two seal grooves
Deeply require as 2.5mm～2.6mm, the tolerance being equivalent to groove depth is 0.1mm, and therefore, the tolerance of this groove depth is less.And
During processing this two seal grooves, two reasons are had to will likely result in generation problem：The abrasion of first cutter, it two is
Because front cover for vehicle is an aluminium casting, the ductility of aluminum is big, and groove knife can be stained with aluminium skimmings when processing groove depth on cutter, so can make
The diameter becoming seal groove becomes big or impact seal groove machining accuracy.And this two problems are under existing technique manufacturing method
Cannot thoroughly be solved, they are caused a problem in that at all：The groove depth size of seal groove can occur overproof that is to say, that
Groove depth size can be more than 2.6mm, and the groove depth of seal groove is once overproof, and, after installing sealing ring, this is at two for front cover for vehicle
Sealing property is greatly reduced, and therefore, front cover for vehicle will occur the phenomenon of oil leak.Therefore, front cover for vehicle will be through before warehouse-in
The detection crossing seal groove groove depth could be put in storage.But, in prior art to the detection of this groove depth typically by dial gauge or
Person micrometer is being detected.
" the annular groove depth detection limit of disclosed Patent No. 201120413815.4 on State Intellectual Property Office website
The patent of invention of tool ", it includes magnetic stand, the support being fixed on magnetic stand and the dial gauge being arranged on this support,
Dial gauge is made up of measurement bar and table body, and magnetic stand bottom is lined with increases frock.It, in measurement, need to prepare a flatness
One, higher platform, if workpiece is too high, magnetic stand can not meet when requiring, and also needs to prepare one to increase frock.It makes
With process it is：First dial gauge is adjusted to O position in datum level, then gently measurement bar is lifted and put in measuring tank to be measured, then
Read dial gauge numerical value, now reading is groove depth size reading.
But, there is problem below in the detection means of above-mentioned this groove depth：
1) because magnetic stand and workpiece are being individually present of disengagement, but also higher putting down of flatness must be prepared
Platform, magnetic stand is to adsorb on platform, and therefore, the position of one side magnetic stand and workpiece inherently exist certain
Error, this can lead to the data measured to there is inaccuracy in itself；The fixed property of another aspect magnetic stand is not high, and one
Denier has loosening or movement situation to occur, and the reading of dial gauge will have error；
2) workpiece and platform can independently move, and therefore, in measurement, workpiece must not have movement, once there being touching to make workpiece
Shift, the reading of dial gauge also has error；
3) the detection means integral installation of this structure requires too high, troublesome poeration, wastes time and energy, production efficiency is extremely low
Under.
