The hole machined of medium and small part is the common lathe in general machining workshop.
As shown in Figures 2 and 3, in the prior art, in the main shaft offsetting spring structure of radial drilling machine, reset spring 14 passes through
Reset spring fixing screws 21 are installed in spring case 15, and tooth sector 18 passes through fixed round pin 13 and connects with the positioning of spring shaft 17
It connects, by twisting force on spring shaft 17, spring shaft 17 is supported reset spring 14 by needle bearing 16, and spring shaft 17 passes through steering
Gear 18 and bearing 19, support shaft 20 pass to the shaft gear 1 on transmission shaft 2, then connected by the control of clutch 12 or
It disconnects and coupling with worm gear 3, worm screw 4, completing work feed or the resetting movement of main shaft.When clutch 12 combines, by snail
Bar 4 drives worm gear 3 to overcome the torsion of reset spring 14 that centripetal force is transmitted to the shaft gear 1 on transmission shaft 2, then is transmitted to main shaft
The rack gear of set realizes axis feeding movement.When clutch 12 disconnects, cutting worm gear 3 couples with shaft gear 1, worm screw 4
It dallies with worm gear 3, main shaft is sprung back by the twisting force of reset spring 14 to be resetted.Disadvantage is that reset spring torsion passes
It is longer and complicated to pass chain.
Summary of the invention
The purpose of the present invention is to provide a kind of radial drilling machine main shaft offsetting spring structure applied on radial drilling machine, with
It is more superior to reach machine tool capability, structure is more simplified, Yi Zao, preferably uses, operates light, adjustment, maintenance more easily purpose.
The technical scheme is that
A kind of radial drilling machine main shaft offsetting spring structure, which includes: transmission shaft tooth
Wheel, transmission shaft, worm gear, worm screw, reset spring fixing screws, spring base positioning pin, feeding handle, feeding handle seat, dial,
Reset spring, return spring holder, specific structure are as follows:
Shaft gear, worm gear, feeding handle seat are installed, shaft gear is mutually nibbled with the rack gear on collar bush on transmission shaft
It closes, worm gear and worm screw form Worm and worm-wheel gearing, and dial is installed in the outside of feeding handle seat, and an end face of dial is set
Return spring holder is set on the outside of shaft gear, reset spring is installed in return spring holder, the groove at side surface of feeding handle seat
Middle installation feeding handle, reset spring are located at behind feeding handle and dial, are directly set around on shaft gear.
The radial drilling machine main shaft offsetting spring structure, the both ends that reset spring pre-tightens torsion are individually fixed in radial drill
On the spindle box and shaft gear of bed.
The radial drilling machine main shaft offsetting spring structure, return spring holder pass through spring base positioning pin location and installation.
The radial drilling machine main shaft offsetting spring structure, reset spring are installed on reset by reset spring fixing screws
In spring base.
The radial drilling machine main shaft offsetting spring structure, reset spring are to reset volute spring.
The advantages of the present invention are:
The transformation of the offsetting spring structure of radial drilling machine main shaft of the present invention, make structure it is more reasonable, it is compact, simplified, replacement,
Maintenance, adjustment are very simply, conveniently.

Specific embodiment
As shown in Figure 1, radial drilling machine main shaft offsetting spring structure of the present invention, specifically includes that shaft gear 1, transmission shaft
2, worm gear 3, worm screw 4, reset spring fixing screws 5, spring base positioning pin 6, feeding handle 7, feeding handle seat 8, dial 9,
Reset spring 10, return spring holder 11 etc., specific structure is as follows:
Shaft gear 1, worm gear 3, feeding handle seat 8 be installed, on shaft gear 1 and collar bush 22 on transmission shaft 2
Rack gear is meshed, and drives the main shaft 23 in collar bush 22 and collar bush 22 to feed by shaft gear 1.Worm gear 3 and worm screw 4
Worm and worm-wheel gearing is formed, when clutch 12 is combined with shaft gear 1, Worm and worm-wheel gearing is transmission shaft tooth
Wheel 1 provides power.Dial 9 is installed in the outside of feeding handle seat 8, and the end face setting return spring holder 11 of dial 9 is in biography
1 outside of moving axis gear, for return spring holder 11 by 6 location and installation of spring base positioning pin, reset spring 10 is solid by reset spring
Determine screw 5 to be installed in return spring holder 11, feeding handle 7 is installed in the groove at side surface of feeding handle seat 8.Wherein, bullet is resetted
Spring 10 is to reset volute spring, and reset spring 10 is located at behind feeding handle 7 and dial 9, is directly set around transmission shaft tooth
On wheel 1.
As depicted in figs. 1 and 2, the both ends that reset spring 10 pre-tightens torsion are individually fixed in the master of radial drilling machine by the present invention
On axle box and shaft gear 1, when clutch 12 couples, worm screw 4, worm gear 3 pass power to shaft gear 1, thus band
The rack gear of dynamic collar bush 22 realizes the feed motion of main shaft 23.When clutch 12 disconnects, cutting worm screw 4, worm gear 3 and transmission shaft
The transmission of gear 1, shaft gear 1 drive the rebound of main shaft 23 to reset in the case where reset spring 10 pre-tightens twisting force.
Structure of the invention is greatly simplified, and new construction makes the torsion of reset spring 10 directly act on transmission shaft tooth
On wheel 1, cumbersome torsion transmitting is eliminated.Due to moving to reset spring 10 behind feeding handle 7 and dial 9, debugging
Or it when maintenance reset spring 10, only needs shift scale disk 9, feeding handle 7 that can be installed, be adjusted, maintenance work, reaches
Structure is simple, repairs well, handy purpose.
