Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1
Referring to Fig. 1, in the embodiment of the present invention, a kind of engine air inlet tube automatic welder, including rotating mechanism and collet,
The rotating mechanism is made of welding machine chuck 12, bearing 17, bearing cap 19 and stepper motor 15, the bearing position peace of welding machine chuck 12
It is fixed on fuselage 14 after dress bearing 17 by the second nut 18 and bearing cap 19, is pacified on gear engagement position and stepper motor 15
13 engaged transmission of gear of dress, makes welding machine chuck 12 make rotating motion, while carbon brush 20 is installed in the outer circle position of welding machine chuck 12
Keep good earth.
The collet by axis 1, pull rod 9, preceding expansion core 5, cylinder 16, valve expansion set 4, positioning sleeve 3 and rear expansion core 2 is divided to form.
After 1 end flanges of axis connect fastening by bolt 11 with welding machine chuck 12, collet is set to make rotating motion, pull rod 9 is worn
Cross axle center, left end is fastened by the first nut 8 with preceding expansion core 5, and right end is bolted on the piston rod of cylinder 16, when cylinder 16
After piston tenses to the right, expansion core 5 is moved right before pull rod 9 drives, and makes point 4 enlarged outside diameter of valve expansion set, from internal swelling pipe fitting 26
Gap is eliminated to its full circle and concentric with bend pipe 27.
Preceding expansion core 5 keeps coaxial by shaft hole matching with rear expansion core 2 and can slide back and forth, and divides valve expansion set 4 by the second elasticity
Retaining ring 10 is integrated rear and preceding expansion core 5 and rear expansion core 2 by spring force deflation and is felt relieved by cone match, divides valve expansion set 4 right end
Outer circle and 3 inner circle of positioning sleeve cooperate, and 3 outer diameter of positioning sleeve and 26 inner circle of pipe fitting cooperate, and feel relieved to pipe fitting 26, rear expansion core 2 with
Axis 1 is connected through a screw thread.
Thrust bearing 6 is installed inside preceding expansion core 5, and is fixed in preceding expansion core 5 by the first circlip 7,9 left end of pull rod
It is connected as one by the first nut 8 and preceding expansion core 5, and keeps axially fastening, radial rotatable state, expansion core 5 is revolved before avoiding
When turning, loosen the first nut 8.
Embodiment 2
Please refer to Fig. 2-4, in the embodiment of the present invention, a kind of engine air inlet tube automatic welder, on the basis of embodiment 1
On, for axis 1 because of requirement, length is longer, and left end is larger with respect to the circular runout of right end flange face, is unable to satisfy welding and wants
It asks, so adding welding gun spacing device, wherein welding gun 25 is fixed at the collet of spacing bracket 23,23 lower part of spacing bracket dress
There are two the idler wheel 24 relative to the distribution of 25 axis span centre of welding gun, 23 top of spacing bracket and bracket 21 are made by shaft hole matching
