The movement of member, accelerates operating efficiency.
The specifically used process of instrument can refer to the example below：Hard thing is filled between abrasive disk and connecting plate two ends first,
Bolt in the middle of adjusting so that abrasive sheet bends to certain radian, bearing shell being ground work in grinding plate surface, until
Bearing shell surface is fitted completely with abrasive sheet, then grinding is completed, after the completion of bearing shell can be placed on article storage plate on supporting frame
On, then proceed to the grinding work of other bearing shells.Regulation adjusting means, makes abrasive sheet move a segment distance, fast changeable work
Make region, be easy to use the cleaning and cooling in region, operating efficiency and quality are not influenceed.
The beneficial effects of the invention are as follows：Using two-piece unit structure, centre with the addition of transmission device and be connected as transition,
The height of support body makees suitable height for people's gymnastics, it is ensured that the comfortableness of operator's work, saves space, and desktop can adjust phase
To position, walking about for operator is reduced, increased work area, save the working time, improve operating efficiency；Article is deposited
Putting plate can place product and instrument with supporting plate, it is ensured that the cleaning and order of processing site；Adjusting apparatus use trapezoidal spiral shell
Line structure, with auto-lock function, it is therefore prevented that the vibration of desktop, it is ensured that the precision of processing, is filled using polished rod as middle transition
Put, polished rod surface luminous intensity is good with linearity, it is ensured that smooth during regulation, it is easy to assembly using the assembling mode of compact heap, and
And polished rod is difficult to slide；The radian of desktop can be adjusted, and can simultaneously meet the processing work in each face, be effectively guaranteed bearing
The machining accuracy of bearing shell, improves motor manufacturing precision and overall performance, reduces workload and working time.Traditional processing side
Formula easily increases error in surface roughness, and this fitting device is effectively reduced processing and is missed by the way of integral grinding
Difference and percent defective, shaggy to be ensured well, fit clearance has obtained effective guarantee with size, so as to subtract
Unnecessary loss is lacked.
