Summary of the invention:
The purpose of this utility model provides does not a kind ofly have the low bearing in magnetic field, precision height, processing cost with roller ball basal plane grinding attachment, to overcome the deficiency of prior art.
Technical solution of the present utility model is: a kind of bearing roller ball basal plane grinding attachment, it comprises body, grinding wheel unit and work piece post-positioning device are housed on body, it is characterized in that: the body upper bearing (metal) is supported with guide roller axis 18, the guide roller axis 19 that be arranged in parallel, one termination transmission mechanism of guide roller axis 18, guide roller axis 19, the other end is equipped with deflector roll 6 and deflector roll 7 respectively, is provided with pinch roller 3 above between deflector roll 6 and the deflector roll 7, and pinch roller 3 connects thrust unit 21.
Described thrust unit 21 is a cylinder.
Connect materials device between described deflector roll 6 and the deflector roll 7, feeding device comprises hopper 20, and the outlet of last hopper 20 is positioned at deflector roll 6 and deflector roll 7 places, and the other end of last hopper 20 connects material impeller 1.
Described material loading impeller 1 is a cylinder.
The structure of described transmission mechanism is: synchronizing wheel 8 and synchronizing wheel 9 are equipped with in the termination of guide roller axis 18, guide roller axis 19, be connected between synchronizing wheel 8 and synchronizing wheel 9 and the synchronizing wheel 10 and be with 22 synchronously, belt pulley 13 is coaxial with synchronizing wheel 10, connect driving-belt 16 between belt pulley 13 and the belt pulley 12, belt pulley 12, belt pulley 13, synchronizing wheel 10 equal bearings are on body.
The utility model compared with prior art has following advantage: no magnetic field produces in the course of work, detector is not influenced by magnetic induction, detects accurately, and workpiece does not have magnetization phenomenon, need not demagnetization after the processing handles, save processing step, thoroughly solved workpiece residual magnetism problem, do not have the absorption of grinding powder in the time of grinding, improve each machining accuracy, since after orientate as fixedly, length dimension inaccuracy problem makes the good product quality cost low when having solved cylinder and living the location.
Description of drawings:
Fig. 1 is the utility model specific embodiment overall structure schematic top plan view;
Fig. 2 is that schematic diagram is looked on the utility model specific embodiment overall structure right side.
A step describes when below in conjunction with accompanying drawing the specific embodiment of the present utility model being done:
As shown in the figure: 18,19 be respectively guide roller axis, in the cartridge housing 17 bearing be housed, guide roller axis 18,19 is supported on the body, diaxon be arranged in parallel.The right-hand member head binding of guide roller axis 18 is connected to big guide wheel 7, and the height and position that the right-hand member head binding of guide roller axis 19 is connected to little guide wheel 6, two guide wheel places is as the criterion so that the top is identical.Be provided with pinch roller 3 above between two guide wheels, pinch roller 3 usefulness axle is supported on the pinch roller frame 2, and pinch roller frame 2 joins with thrust unit 21.Thrust unit 21 is a cylinder, joins with air control unit.Piston rod in the cylinder connects with pinch roller frame 2 fastening suits.Pneumatic means drives pinch roller frame 2 drive pinch rollers 3 and can pump.
