The utility model content
The technical problem that the utility model will solve provides a kind of Stability Analysis of Structures, reliable, the soldering cramping apparatus rotating mechanism being convenient to rotate.
For solving the problems of the technologies described above; The soldering cramping apparatus rotating mechanism that is provided comprises base; Be connected with bolster on the base; Be rotatably connected to the rotary sleeve that can be connected with welding positioner on the bolster, its design feature is: cone bearing is equipped with in the bottom between bolster and the rotary sleeve, the deep trench bearing is equipped with on top.
The top of rotary sleeve is provided with heavy stand, is overlapped with pressure plates on the heavy stand, is bolted with hold-down bolt between pressure plates and the bolster top.
The sidepiece of bolster is equipped with the air inlet pipe of stretching out, and escape pipe is equipped with at the top of bolster, and bolster inside is provided with the cross passage of UNICOM's air inlet pipe and escape pipe.
After adopting said structure; Welding positioner is connected on the rotary sleeve; Base is fixed on the fixed support, and deep groove ball bearing plays the radially effect of constraint, and cone bearing mainly plays the effect of bearing weldering tire weight; Deep groove ball bearing and cone bearing form 2 radially constraint effects, thus make Stability Analysis of Structures, reliable, be convenient to rotation.The utility model only need be used deep groove ball bearing and cone bearing of a relative low price, can satisfy the requirement of radial load, can bear again and generally radially plant lotus, has saved buying expenses greatly.That this kind structure is installed is fairly simple, be convenient to operation, improved production efficiency.
In sum, the utlity model has structure advantage simple, that be convenient to operate is installed, and Stability Analysis of Structures, reliable, production cost practiced thrift greatly.
The specific embodiment
Soldering cramping apparatus rotating mechanism as shown in Figure 1; It comprises base 1, is connected with bolster 2 on the base 1, is rotatably connected to the rotary sleeve 3 that can be connected with welding positioner on the bolster 2; Cone bearing 4 is equipped with in bottom between bolster 2 and the rotary sleeve 3, deep trench bearing 5 is equipped with on top; The assembly structure of cone bearing 4, deep trench bearing 5 is as shown in fig. 1, and its concrete structure is a prior art, repeats no more at this.The top of rotary sleeve 3 is provided with circular heavy stand 6, is overlapped with circular pressure plates 7 on the heavy stand 6, is bolted with hold-down bolt 8 between pressure plates 7 and bolster 2 tops, heavy stand 6 and pressure plates 7 the deflection that has effectively prevented bolster 2 is set.The sidepiece of bolster 2 is equipped with the air inlet pipe 9 of stretching out; Escape pipe 10 is equipped with at the top of bolster 2; Bolster 2 inside are provided with the cross passage 11 of UNICOM's air inlet pipe 9 and escape pipe 10, and source of the gas gets into from air inlet pipe 9 and picks out from escape pipe 10 at last, thus be connected the weldering tire with on the gas instrument.
