Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

In fig. 1-3, the device comprises a 01 main shaft box body, a 02 sleeve main shaft, a 03 main shaft, a 04 AE sensor, a 05 large grinding wheel trimming disc, a 06 pneumatic clamp, a 07 small grinding wheel trimming disc, a 08 processing workpiece, a 09 transition disc, a 10 connecting disc, a 11 hard air rod, a 12 rotary joint, a 13 air pipe joint, a 14 CBN small grinding wheel, a 15 excircle large grinding wheel and the like.

As shown in fig. 1-3, the utility model discloses a compound grinding machine work piece main shaft, anchor clamps, AE, integrated configuration is maintained to emery wheel, including sleeve main shaft 02, the sleeve main shaft 02 outside is the sleeve, the inside gyration of sleeve embeds motor drive main shaft 03, and motor drive main shaft 03 axial is opened there is the main shaft through-hole. The sleeve is installed in the main shaft box body through a right end face screw. The connecting disc 10 is fixed with the right end of the main shaft 03 through a screw and rotates together. A connecting disc through hole is formed in the connecting disc 10, a pneumatic clamp 06 is installed on the inner end face of the right side of the connecting disc 10, a transition disc 09 is installed on the outer end face of the right side of the connecting disc 10, an annular groove is formed in the transition disc 09, and a balance block for dynamic balance can be installed in the groove. An AE sensor 04 moving ring is arranged on the left side of the transition disk 09, and an AE sensor 04 static ring is fixed on the sleeve end face of the sleeve main shaft 02.

The AE sensor 04 is an acoustic emission sensor, and can respond with high sensitivity at a certain frequency.

When the main shaft 03 rotates at a high speed, the AE sensor 04 is driven to rotate together with the rotating ring, and the detected signal on the rotating ring can be transmitted to the machine tool controller through the static ring and then converted into an electric signal for feedback. A large grinding wheel dressing disk 05 is arranged on the right side end face of the transition disk 09, and a small grinding wheel dressing disk 07 is arranged on the right side inner end face of the large grinding wheel dressing disk 05. The large grinding wheel dressing disk 05, the pneumatic fixture 06 and the small grinding wheel dressing disk 07 rotate together with the spindle. The large grinding wheel dressing disk 05 is used for dressing the excircle and the end face of the excircle large grinding wheel 15. The small grinding wheel dressing disk 07 is used for dressing the outer circle and the small end face of the CBN small grinding wheel 14.

The machining workpiece 08 is clamped on the clamping jaws of the clamp 06 through the excircle and the end face. The clamp force comes from the inside cylinder of anchor clamps, and external pressure air source passes through air pipe joint 13 and gets into swivel joint 12, and the inside cylinder of anchor clamps is inserted to rethread hard gas pole 11.

The hard air rod 11 is positioned in the through hole of the connecting disc and the through hole of the main shaft, one end of the hard air rod is connected with the air inlet end of the pneumatic clamp 06, and the other end of the hard air rod is provided with a rotary joint 12.

The sleeve spindle 02 adopts an electric spindle structure.

The pneumatic clamp 06 is a pneumatic clamping jaw.

The working process of the utility model is as follows:
