Detailed Description
As shown in fig. 1, the utility model discloses radial drill main shaft reset spring structure mainly includes: the transmission shaft gear 1, the transmission shaft 2, the worm wheel 3, the worm 4, the reset spring fixing screw 5, the spring seat positioning pin 6, the feed handle 7, the feed handle seat 8, the dial 9, the reset spring 10, the reset spring seat 11 and the like, and the concrete structure is as follows:
the transmission shaft 2 is provided with a transmission shaft gear 1, a worm wheel 3 and a feeding handle seat 8, the transmission shaft gear 1 is meshed with a rack on the main shaft sleeve 22, and the transmission shaft gear 1 drives the main shaft sleeve 22 and a main shaft 23 in the main shaft sleeve 22 to feed. The worm wheel 3 and the worm 4 form a worm gear transmission mechanism, and when the clutch 12 is combined with the transmission shaft gear 1, the worm gear transmission mechanism provides power for the transmission shaft gear 1. The outside of feed handle seat 8 installs calibrated scale 9, and one terminal surface of calibrated scale 9 sets up reset spring seat 11 in the transmission shaft gear 1 outside, and reset spring seat 11 passes through spring seat locating pin 6 location installation, and reset spring 10 passes through reset spring set screw 5 to be installed in reset spring seat 11, installs feed handle 7 in the side fluting of feed handle seat 8. Wherein, the reset spring 10 is a reset scroll spring, and the reset spring 10 is positioned behind the feed handle 7 and the dial 9 and directly wound on the transmission shaft gear 1.
As shown in fig. 1 and 2, the present invention fixes the two ends of the pre-tightening torque of the restoring spring 10 on the spindle box and the transmission shaft gear 1 of the radial drilling machine respectively, and when the clutch 12 is coupled, the worm 4 and the worm wheel 3 transmit the power to the transmission shaft gear 1, so as to drive the rack of the spindle sleeve 22 to realize the feeding motion of the spindle 23. When the clutch 12 is disconnected, the transmission of the worm 4, the worm wheel 3 and the transmission shaft gear 1 is cut off, and the transmission shaft gear 1 drives the main shaft 23 to rebound and reset under the action of the pre-tightening torsion of the reset spring 10.
The utility model discloses a structure has obtained very big simplification, and new construction makes reset spring 10's torsion direct action on transmission shaft gear 1, has saved loaded down with trivial details torsion transmission. Because the return spring 10 is moved to the back of the feed handle 7 and the dial 9, when the return spring 10 is debugged or maintained, the installation, adjustment and maintenance can be carried out only by moving the dial 9 and the feed handle 7, thereby achieving the purposes of simple structure, easy maintenance and convenient use.
