Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As shown in Figure 1, 2, electric tube expander includes: Zhang Tou mechanism, swollen head driving mechanism 3, support 4.
The Zhang Tou mechanism includes: elastic expansion head 1 and expanding rod 2.
The elastic expansion head 1 be it is hollow, there is a step 102 in middle vacancy, and the radial opening seam of several equal parts is arranged in shell one end
Gap 101 can be elastically compressed, and the other end is equipped with convex section 103.
The natural opening dimension D1 of above-mentioned elastic expansion head 1 determines the tube expansion size of copper pipe, the diameter of the boss section 103
Must strictly it cooperate with the internal diameter of copper pipe 10, it is excessive to will be unable to enter copper pipe 10, it is too small to can be carried out tube expansion.
The expanding rod 2 includes first body of rod 21 and second body of rod 22.First body of rod 21 includes the same end of sub warhead
Portion 201, facilitates expanding rod to enter copper pipe, further includes supporting section 202, boss face 203, thread segment 204.First body of rod 21 passes through
Its thread segment 204 is threadedly coupled with second body of rod 22.
The elastic expansion head 1 is set on outside expanding rod 2, and axial movement position one end passes through the end face 205 of second body of rod 22
It limits, the other end blocks step 102 by the boss face 203 of first body of rod 21 to limit.
It is illustrated in figure 2 state when swollen alliteration pipe, D1 is tube expansion size, D1 size when elastic expansion head 1 opens naturally
It is maintained in tube expansion by the supporting section 202 of first body of rod 21.
As shown in Fig. 1 and Fig. 9, the swollen head driving mechanism 3 includes motor 301, gear 302, rack gear 303, motor installation
Plate 304, sliding rail 305, slide 306.
The motor 301 is mounted on motor mounting plate 304, and gear 302 is equipped on output shaft, is nibbled with gear 302
On the carrier 4, on the carrier 4, slide 306 corresponding thereto is mounted on motor for the installation of sliding rail 305 for the rack gear installation of conjunction
On mounting plate 304.
2 one end of expanding rod of the Zhang Tou mechanism is mounted in expanding rod fixing seat 307, and the expanding rod fixing seat 307 is mounted on
On motor mounting plate 304.
Motor 301 is rotated with moving gear 302, and by engaging the effect of rack gear 303, Shi Zhangtou mechanism is along expanding rod 2
Axis direction it is mobile.
Action process:
State as shown in Figure 5, swollen head driving mechanism push Zhang Tou mechanism to enter copper pipe, and elastic expansion head 1 is compressed, due to boss section
Frictional force between 103 and internal diameter of copper pipe, so elastic expansion head 1 can withstand end face 205.
State as shown in Figure 6, swollen head driving mechanism 3 push Zhang Tou mechanism to come out out of copper pipe, until elastic expansion head is convex
Section 103 comes out completely out of copper pipe out, and elastic expansion head 1 opens naturally at this time, since the greatest diametrical dimension of Zhang Tou mechanism is all small
In internal diameter of copper pipe size, it is possible to smoothly pass through copper pipe.
As shown in fig. 7, swollen head driving mechanism 3 starts back to pull Zhang Tou mechanism, due to boss after elastic expansion head 1 is released
Section 103 and internal diameter of copper pipe between frictional force and make elastic expansion head 1 be less than expanding rod movement speed, so elastic expansion head 1 can be made
A distance is moved with expanding rod opposite direction, the place of cracking of 1 front end of elastic expansion head is allowed to be stuck at the supporting section 202 of expanding rod, until convex
Table top 203 blocks immovable.Elastic expansion head maintains tube expansion dimension D 1 by the support of supporting section 202 at this time, carries out tube expansion standard
It is standby.
As shown in figure 8, swollen head driving mechanism 3, which pulls on Zhang Tou mechanism, enters copper pipe distending copper pipe, until swollen complete
Then copper pipe is drawn out out of copper pipe, carry out tube expansion preparation next time.
As shown in Figure 1, expanding rod 2 can be supported by several supporting blocks 308, the branch in order to make expanding rod smoothly into and out of copper pipe
The each correspondence of bracer 308 is mounted on a slide 306, and such supporting block 308 can steadily be moved along sliding rail 305.
According to the variation of specification of workpieces, support 4 and Zhang Tou mechanism thereon integrally need level or move up and down sometimes,
So can also increase translational drive mechanism 5 and lift drive mechanism 6, the translational drive mechanism 5 and lift drive mechanism 6 are all pacified
In rack 7.
The translational drive mechanism 5 include motor 501, gear 502, rack gear 503.The motor is mounted on crane
Gear 502 is installed, the installation of rack gear 503 engaged is on the carrier 4 on 606, on output shaft.
In order to enable support steadily to move, sliding rail slide guiding mechanism is provided between support 4 and crane 606
504。
The lift drive mechanism 6 includes motor 601, worm gear elevator 602, screw rod 603, shaft coupling 604, transmission shaft
605 and crane 606.
The worm gear elevator 602, screw rod 603 and crane 606 are symmetricly set in rack 7, as shown in Figure 10.Institute
It states motor 601 to be mounted in rack 7, the worm gear elevator 602 on output shaft and one side connects, described 603 one end of screw rod and liter
Drop machine 602 connects, and the other end is connect with crane 606, and 605 both ends of transmission shaft are connected separately with snail by shaft coupling 604
Take turns elevator 602.
The worm gear elevator 602 on one side is driven by motor 601, drives screw rod 603 to move up and down, while passing through transmission shaft
605, make the worm gear elevator 602 of another side that screw rod 603 be driven to move up and down, to realize the fortune up and down of both sides crane 606
It is dynamic.
