Charging ram 32 transports horizontally forward, carries out the clamping in horizontal direction to the workpiece being located on positioning tool 51.
Driver 33 and pusher 22 are preferentially adopted as oil cylinder in the present embodiment, naturally it is also possible to it is adopted as cylinder,
Driving can be played the role of.
Certainly, rubber block 34 can be set in the end of charging ram 32, has made charging ram 32 after contacting with workpiece, had
There is certain buffering capacity, workpiece caused by direct rigid contact is avoided to deform.Further, it is additionally provided in mounting base 5
Alignment block 53 is provided through alignment hole (not illustrating in figure) on alignment block 53, and alignment block 53 can be set multiple, is pushed away
Expect that bar 32 passes through the alignment hole, the end of charging ram 32 can effectively be made to keep alignment, it will not sideslip.
The following are the process to the vertical grinding machine of Double End to be further elaborated, and workpiece is placed on positioning work first
It fills on 51, then drives driver 33, draw close charging ram 32 to workpiece, after charging ram 32 and workpiece are contradicted,
Under the action of other side positive stop end 511, that is, realize the positioning in horizontal direction.Then, the piston of 2 pusher 22 of pressing device
Bar driving, rotates bull stick 23 with pivotal point, i.e. the briquetting 241 of compression bar 24 rotates clockwise, and gradually declines, and finally contradicts and arrives work
It, can be to being clamped on vertical direction after part.After completing to clamp, pedestal is fed by mounting base 5,2 and of pressing device
The synchronization of horizontal clamping device 3 is transported forward, until arriving Working position, the both ends of workpiece are ground by the grinding wheel 41 of grinding head device 4 simultaneously
It cuts, after grinding repeatedly, completes processing, reach high-precision requirement.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
