Specific embodiment
As depicted in figs. 1 and 2, a kind of auto-feeder of rail bonding drill includes mainboard 1, guide post 2, mounting body
3, guide sleeve 4, double output shaft direct current generator 5, sleeve 6, final motion screw axis 7, thrust pedestal 8, the first nut body 9, support pedestal
10, the second nut body 11 and connecting rod 12；Wherein the first nut body 9 is fixedly connected with thrust pedestal 8, the second nut body 11 and branch
Support pedestal 10 is fixedly connected；7 right end external screw thread of final motion screw axis forms the screw pair matched, fine motion spiral shell with the second nut body 11
The intermediate external screw thread of spin axis 7 forms the screw pair matched with the first nut body 9, and the left end of final motion screw axis 7 is setting keyway
Shaft part forms relatively-movable mating connection by flat key with the right end of sleeve 6；The left end of two parallel guide posts 2 with
Mainboard 1 is cooperatively connected and is fixed by screw, and the right end of two parallel guide posts 2 is cooperatively connected and passes through with support pedestal 10
Screw is fixed；Mounting body 3 is formed a fixed connection with thrust pedestal 8 by the threaded connection at 12 both ends of connecting rod, double output shaft
Direct current generator 5, which is bolted, is fixed on mounting body 3, and mounting body 3, thrust pedestal 8 are both provided with two guide sleeves 4,
Guide sleeve 4 and guide post 2 form moveable mating connection；The right end output shaft and sleeve 6 of the double output shaft direct current generator 5
It is formed a fixed connection by flat key and holding screw, left end output shaft drives bit.
As shown in Fig. 2, one feeding process final motion screw axis 7 is relative to first when setting the auto-feed length of needs as l
The moving distance of nut body 9 is l1, final motion screw axis 7 is l relative to the moving distance of the second nut body 112If the first nut body
9 lead is s1, the lead of the second nut body 11 is ms1(m > 1) when rotating forward such as double output shaft direct current generator, drives fine motion spiral shell
Spin axis 7 is moved to left with respect to the second nut body 11, since the first nut body, the second nut body rotation direction are identical, 9 phase of the first nut body at this time
Final motion screw axis 7 is moved to right, since the lead of the second nut body 11 is ms1Lead greater than the first nut body 9 is s1, fine motion spiral shell
7 per revolution of spin axis, it is (m-1) s that the first nut body 9, which moves to left distance relative to the second nut body 11,1, due to the second nut body
11 is fixed, and the first nut body 9 is to be fixedly connected with thrust pedestal 8, mounting body 3 and double output shaft direct current generator 5, therefore
First nut body 9 drives double output shaft direct current generator 5 to move to left along two parallel guide posts 2, realizes feed function；By above-mentioned
Analysis, it is available: l: l1∶l2=(m-1) s1∶s1∶ms1=(m-1): 1: m, therefore l1=l/ (m-1), l2=ml/ (m-1),
In order to avoid movement interference, while guaranteeing that screw pair remains certain screwing length,
By setting reasonable m, s1It can control the amount of feeding (m-1) s of 5 every revolution of double output shaft direct current generator1, keep away
Exempt from the too small low efficiency of the amount of feeding, the amount of feeding is excessive the problem of bit freezing occurs.
