Embodiment Construction

[0014] Since the present invention can move in three directions, for ease of understanding, the coordinate axes are defined as follows: the direction from the moving tailstock 1 to the geared motor 6 is the Z direction (that is, the horizontal track laying direction), the direction from the workpiece to the horizontal track 7 is the Y direction, and the polishing belt 310 The direction of movement is the X direction.

[0015] like figure 1 , 2 As shown, the screw drilling tool rotor polishing machine tool device of the present invention includes a frame 2 on which a reduction motor 6 is installed on one side and a moving tailstock 1 is installed on the other side, and is arranged on the frame 2 to be located at the moving tailstock 1 and the deceleration The horizontal track 7 between the motor 6, and the polishing assembly 3 that is installed on the horizontal track 7 and can move back and forth along the horizontal track 7 to polish the workpiece, a rotary shaft head 5 is i...

Abstract

The invention discloses a positive displacement motor rotor polishing machine tool device which comprises a rack, horizontal rails and a polishing assembly. A decelerating motor is mounted on one side of the rack, a movable tailstock is mounted on the other side of the rack, the horizontal rails are mounted on the rack and are positioned between the movable tailstock and the decelerating motor, the polishing assembly capable of moving back and forth along the horizontal rails to polish workpieces is mounted on the horizontal rails, a rotating shaft head is mounted on the decelerating motor, a chuck corresponding to the movable tailstock is mounted on the other side of the rotating shaft head, and the chuck and the movable tailstock form a clamping device. A tripod is mounted on the polishing device, and thus any complex surface can be polished in the direction of front, back, left, right, up and down freely, polishing accuracy is high, and cost and labor are saved.

Description

technical field [0001] The invention relates to the field of mechanical polishing, in particular to a polishing machine tool for polishing the rotor of a screw drilling tool. Background technique [0002] Helical curved surface screws are widely used in compressors, refrigerators, screw pumps, etc. With the continuous increase of the application range of helical curved surface screws, the forming mechanisms of helical curved surfaces are different, and the screw profiles are also complex and diverse, which brings great difficulties to the processing of the screw. It was very difficult to come. The rotor or mandrel of the screw drilling tool has strict requirements on the surface line type and high dimensional accuracy. After milling, the tool marks are obvious and must be polished. At present, most of them are polished manually. The work efficiency and precision of this polishing method are not very high, which seriously affects the production efficiency of products. In ad...
