In order to solve the problem of prior art, the utility model comprises: with the lathe bed of tailstock; Be located at being used for positioning workpieces and driving the chuck that workpiece rotates on the described lathe bed; The abrasive band that is used for polishing workpiece; Be used for setting up the abrasive belt wheel in abrasive band; Be used for the fixedly workbench of abrasive belt wheel; Be used for the chuck drive motor of drive chuck rotation and be used for the pushing motor that push work platform moves; Described lathe bed both sides are provided with longitudinal rail, and the workbench foot is provided with sliding sleeve, described sliding sleeve be socketed on the outer so that workbench of longitudinal rail when being subject to pushing motor and promoting longitudinally guide rail move back and forth and near or away from chuck.
Further, the utility model also comprises the tooth axle of being located at the pushing motor output and rotated by motor-driven, and described workbench is provided with the tooth bar with this tooth axle engagement.
Further, the utility model comprises that also described hydraulic jack has expansion link for regulating the abrasive band at the hydraulic jack perpendicular to the height and position on the direction of chuck main shaft, this expansion link be connected with abrasive belt wheel and when flexible the driving abrasive belt wheel move.
Further, the utility model also comprises a control module and is used for the displacement transducer of detection operations platform positional information that described displacement transducer is connected with control module by signal.
Further, the utility model also comprises for the hydraulic locking oil cylinder that tailstock is locked on the lathe bed.
Described tailstock is provided with the hand handwheel that cooperates the top of gripper chuck clamping of workpieces and pass through manually to promote top movement.
Further, described abrasive belt wheel is three and arranges the formation equilateral triangle.
Compared with prior art, the beneficial effects of the utility model are:
Grinding machine of the present utility model comprises lathe bed, and lathe bed is provided with chuck and abrasive band, and workpiece is arranged on the chuck, chuck is subjected to the chuck drive motor-driven and rotates around himself main shaft, the abrasive band is set up on the workbench by abrasive belt wheel, and it is mobile that workbench is promoted by pushing motor, thus near or leave chuck.Therefore, by the position of adjusting operating platform, just capable of regulating fixedly guarantees precision and the fineness of institute's converted products to the polishing position of excircle of workpiece in the abrasive band, eliminates uneven after the processing, improves the qualification rate of product.Particularly, the utility model is also regulated the abrasive band perpendicular to the height and position on the direction of chuck main shaft by hydraulic jack, more can guarantee to process the flatness of rear surface of the work.

The specific embodiment
Below in conjunction with accompanying drawing structure of the present utility model is done detailed explanation and explanation, but be not to be restriction to the utility model structure.
Referring to Fig. 1, the utility model comprises lathe bed 1 and is located at chuck 2 and workbench 3 on the lathe bed; Lathe bed 1 two side ends is provided with longitudinal rail, and tailstock is provided with tailstock 6, and chuck 2 is located at the lathe bed leading section.Be provided with abrasive belt wheel 4 on the workbench 3, can be set up in the abrasive band 5 that excircle of workpiece polishes on the abrasive belt wheel 4, three abrasive belt wheels 4 are arranged and are formed equilateral triangle, such as Fig. 3.
As shown in Figure 2, workbench 3 is located between chuck 2 and the tailstock 6, and its foot is provided with sliding sleeve 301, and sliding sleeve 301 is socketed on outside the longitudinal rail 302, thus when being subject to pushing motor 303 and promoting longitudinally guide rail 302 move back and forth.Pushing motor 303 is located on the lathe bed 1, and its output drives tooth axle 304 by transmission system, and tooth axle 304 and tooth bar 305 engagements that are fixedly arranged on the workbench 3 move forward and backward thereby drive workbench when motor pushing, finish near or away from the action of chuck.Be located at the positional information of the displacement transducer 7 detectable workbench 3 on the lathe bed 1, and the signal that detects is passed to control module, control module sends signal controlling pushing motor 303 again and rotates, to realize the accurate location of workbench.
