In described T shape slide block A19 and T shape slide block B 20, respectively have two row's four row axial holes, supporting A11 and supporting B14 can be arranged in the axial hole that T shape slide block A19 is different with T shape slide block B 20.
Described magnetic pole 10 is fixed on connector 8 through bolt 9.
Described main shaft 1 connects connector 8 through kidney-shaped key 2.
Described magnetic coil 3 one sides are provided with end-blocking pitch 6.
Described coil case 4 is through bolt 16 connection frames 21, and frame 21 is fixed on workbench through bolt 17 and nut 18.
Embodiment
On the circumference of coil case 4, offer a hole, connect from lathe the hole that two wires 5 are offered through coil case 4, receive on magnetic coil 3.Open switch, after energising, the magnetic force that magnetic coil 3 produces, passes to magnetic pole 10 by connector 8.
T shape guide groove 7 has the circle-shaped guide groove of T shape, on T shape slide block A19 and T shape slide block B 20 circumference, have deep-slotted chip breaker, T shape slide block A19 and T shape slide block B 20 lead with T shape guide groove and M10X30 hexagon socket head cap screw 15, and T shape slide block A19 and T shape slide block B 20 move as circumference in the guide groove of T shape guide groove 7.
T shape slide block A19 and T shape slide block B 20 respectively have two row's four row screw holes, and supporting A11, supporting B14 are arranged in the axial hole that T shape slide block A19 is different with T shape slide block B 20.
Supporting A11, supporting B14 offer kidney slot, can in T shape slide block A19 and T shape slide block B 20, lead with the screw 13 of M6X20, radially move.
T shape slide block A19 and T shape slide block B 20 move as circumference in the guide groove of T shape guide groove 7, can choose the supporting-point of Difference angles on circumference.
Supporting A11, supporting B14 are arranged in the axial hole that T shape slide block A19 is different with T shape slide block B 20, can meet the demand of workpiece spindle to diverse location location.
Frame 21 is fixed on workbench with square head bolt 17 and the M10 nut 18 of 2 M10X40; Coil case 4 and frame 21 are linked up with the hexagon socket head cap screw 16 of 4 M10X25; Magnetic coil 3 is arranged in coil case 4; Two wires 5 that join with switch, through the hole on coil case 4 walls, are connected with magnetic coil 3; Electric wire portals and coil end face end-blocking pitch 6 seals; Hexagon socket head cap screw 12 bolts of T shape guide groove 7 use M12X25 are on coil case 4.
