Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1 and fig. 2, wherein fig. 1 is a schematic structural diagram of a preferred embodiment of a radial drilling machine spindle positioning device according to the present invention; fig. 2 is a schematic top sectional view of the present invention. Radial drill main shaft positioner includes: a placing seat 1; the motor 2 is fixedly arranged at the top of the placing seat 1; the first gear 3 is fixedly arranged on an output shaft of the motor 2; the two supporting plates 4 are fixedly arranged at the top of the placing seat 1; the two screw rods 5 are rotatably arranged on the two support plates 4; the second gear 6 is fixedly arranged at one end of any one screw 5; the first chain 7 is hinged on the first gear 3 and the second gear 6; the two third gears 8 are respectively sleeved on the corresponding screw rods 5; the second chain 9, the said second chain 9 is hinged on two third gears 8; the four driving blocks 10 are respectively sleeved on the corresponding screw rods 5 in a threaded manner; two centre gripping arc plates 11, two centre gripping arc plates 11 are fixed mounting respectively on two corresponding drive piece 10.

The driving block 10 is provided with an internal threaded hole, and the internal threaded hole is in threaded connection with the screw rod 5.

Two rotating through holes are formed in the supporting plate 4, and the two screw rods 5 are respectively connected with the corresponding rotating through holes in a rotating mode.
