The center fixation of described rotary disk is connected with gyroaxis, and the lower ends downward of gyroaxis is passed rotary disk, is movably arranged on the center of base by bearing; The bottom of reference column is threaded on the gyroaxis, the top adjusting nut that has been threaded, and adjusting nut is located at the top of pressing plate.
The edge of described rotary disk upper surface evenly is fixed with polylith arc gripper shoe.
Be fixed with feeler block on the described rotary disk.
The center fixation of described base bottom has the bearing bottom.
Owing to adopted above-mentioned technical scheme, use the supporting milling machine of the utility model, the circumferential plane of flywheel shell of engine is added man-hour, can increase work efficiency, promote work quality.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of anchor clamps among the utility model embodiment;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Embodiment, a kind of bell housing circumferential plane rotary milling fixture as shown in Figure 1 and Figure 2, comprises bogey and compresses assembly.
Described bogey comprises base 1 and the rotary disk 2 that is movably arranged on the base 1, evenly is provided with 7 positioning jacks 20 on the side of rotary disk 2, is fixed with plug housing 3 on the base 1, is plugged with the fastening screw 4 that can cooperate with positioning jack 20 in the plug housing 3.Rotary disk 2 outsides are provided with two groups of rotary disk hold down gags, comprise that the bottom is fixed on adjusting screw(rod) 5, hook-type pressing plate 6 and the adjusting nut 7 on the base 1, the bottom of hook-type pressing plate 6 is movably connected on the base 1, and the upper end of adjusting screw(rod) 5 is upward through hook-type pressing plate 6, is threaded with adjusting nut 7.The center of rotary disk 2 is fixedly connected with gyroaxis 14 by screw 15, and the lower ends downward of gyroaxis 14 is passed rotary disk 2, is movably arranged on the center of base 1 by bearing 19, and the center of base 1 bottom is fixed with bearing bottom 18 by screw 17.
The described assembly that compresses comprises reference column 13, is located at the pressing plate 11 at reference column 13 tops and is located at the location key seat 9 of reference column 13 both sides.The bottom of reference column 13 is threaded on the gyroaxis 14, and the top is provided with pressing plate 11 and adjusting nut 12, and pressing plate 11 is located at the below of adjusting nut 12, is socketed on the reference column 13, and adjusting nut 12 is threaded on the reference column 13.The bottom of location key seat 9 is fixed on the rotary disk 2 by screw 8, and the top is fixed with alignment pin 10.
The edge of described rotary disk 2 upper surfaces evenly is fixed with polylith arc gripper shoe 16.
Be fixed with feeler block 21 on the described rotary disk 2.
The utility model can be processed the bell housing circumferential plane by supporting milling machine, increases work efficiency, promotes work quality.
During use, rotate rotary disk 2 earlier, fastening screw 4 is inserted in the positioning jack 20; Turn adjusting nut 7, it is pressed on rotary disk 2 on the base 1 by hook-type pressing plate 6; Take off adjusting nut 12 and pressing plate 11 from reference column 13, the bell housing of engine is placed on the gripper shoe 16 of rotary disk 2, and the circle hole sleeve that makes the bell housing center is on reference column 13, aperture is enclosed within on the alignment pin 10 around the bell housing center hole; Pressing plate 11 is enclosed within on the reference column 13 again, and the adjusting nut 12 and tightening screwed on makes it by pressing plate 11 bell housing is pressed on the rotary disk 2.At this moment, just can process the circumferential plane of bell housing with milling machine.By rotating the positioning jack of rotary disk 2,4 grafting of conversion fastening screw, can finish the processing of bell housing circumferential plane.
