Fig. 2 is the structural representation of whirligig in Fig. 1;
Fig. 3 is the structural representation of welder in Fig. 1.
Detailed description of the invention
Embodiment: the gas filling bottle rotary welding machine of the present embodiment is used for automatic welding gas filling bottle, its general structure as shown in Figure 1, comprise and be installed on whirligig in frame 3 and welder, wherein whirligig comprises the active rotation body 1 and driven rotation body 2 arranged symmetrically, the welding gun 7 that welder mainly comprises welding gun support 6 and is mounted thereon.
Whirligig as shown in Figure 2, comprises the active rotation body 1 and driven rotation body 2 arranged symmetrically.Active rotation body 1 has intermeshing active motor 1-1 and active rotating shaft 1-2, the end of active rotating shaft 1-2 is provided with the first chuck 1-3 matched with one end outline of gas filling bottle.Driven rotation body 2 has the driven spindle 2-2 be in active rotating shaft 1-2 on same straight line, be provided with the second chuck 2-3 for clamping the gas filling bottle other end in the end of driven spindle 2-2, the inwall of the second chuck 2-3 and the outline of the gas filling bottle other end coincide.
Frame 3 has the first guide rail 3-1 and the second guide rail 3-2 that oppositely arrange, its end is provided with the first cylinder 1-4 and the second cylinder 2-4.Wherein the first guide rail 3-1 coordinates with active rotation body 1, and the first cylinder 1-4 drives active rotation body to do rectilinear motion along the first guide rail 3-1; Second guide rail 3-2 coordinates with driven rotation body 2, and the second cylinder 2-4 drives driven rotation body 2 to do rectilinear motion along the second guide rail 3-2.
Be equipped with the first push rod 1-5 at the axle center part of the 1-2 of active rotating shaft, be equipped with the second push rod 2-5 at the axle center part of the 2-2 of driven spindle, the top of this pair push rod is all stretched in chuck, and is provided with spring.When material loading, push rod is ejected by the gas filling bottle in chuck, during blanking due to active rotation body 1 and driven rotation body 2 along guide rail mutually away from, gas filling bottle ejects by push rod under the action of the spring from chuck.
Welder as shown in Figure 3, the welding gun 7 comprising welding gun support and be mounted thereon, wherein the bottom of welding gun support has and is installed in frame by L shape connector 4, the translation base plate 6-1 that L shape connector 4 has, translation base plate 6-1 does rectilinear motion by leading screw and feed screw nut, the end of leading screw is provided with handle 5, and the direction of this rectilinear motion is orthogonal with the axis of active rotating shaft.Translation base plate 6-1 is provided with vertical column 6-2, column 6-2 is provided with chuck 6-2, chuck 6-2 is provided with crossbeam 6-3.The end of crossbeam 6-3 is provided with pendulous device 6-4, and this device comprises motor-driven screw mandrel and feed screw nut, and welding gun 7 is arranged on the feed screw nut of pendulous device 6-4.
Using the axle center of soldered gas filling bottle as x-axis, vertical direction is set to y-axis, the horizontal direction orthogonal with axle center is set to z-axis, then handle 5 and translation base plate 6-1 are used for the position adjusting welding gun 7 in the z-axis direction, i.e. the level interval of welding gun 7 and gas filling bottle weld seam.Column 6-2 and chuck 6-2 is the position adjusting welding gun 7 in the y-axis direction, i.e. the vertical spacing of welding gun 7 and gas filling bottle weld seam.Pendulous device 6-4 is then the position adjusting welding gun 7 in x-axis, and gas filling bottle carries out swing welding while rotation, forms the movement locus of w shape in commissure.
During use, the gas filling bottle rotary welding machine of the present embodiment completes welding by following steps:
1. material loading, is put into the position that need clamp, namely between a pair chuck after the gas filling bottle two halves shell that need weld closes up.
2. clamping, the first cylinder and the second cylinder drive driving and driven rotary body to move ahead, and the chuck on driving and driven rotary body advances and withstands gas filling bottle separately under first, second cylinder promotes, and is compacted into as a whole.Because the cylinder diameter of the first cylinder is greater than the second cylinder, causes its thrust under identical input air pressure to be also greater than the second cylinder, thus make a pair chuck entirety stop at design runlength place.In clamping process, the stroke of cylinder realizes adjustment according to fixing movement locus, and each cylinder controls by PLC to gas order and time.
3. weld, initiatively electric machine rotation is controlled by PLC, by the gear drive in active rotation body, driven rotary axle and chuck, thus drive whole gas filling bottle to rotate, while rotation, welding gun is started working, circumference soldering is carried out at position along required welding, and after a lap welding has connect, motor and welding gun quit work.In welding process, welding gun can swing along weld seam, to form wider better solder bond face.
4. blanking, driving and driven rotary body unclamps, and gas filling bottle is withstood on centre by the first push rod of being positioned at about it and the second push rod, freely falls under gravity.
So far complete a welding process, then repeat above process, operating personnel only need material loading in whole operation, feeding and attention equipment stability state.
The present invention is that welding gas filling bottle provides a kind of new production model theory, and its principle related to is simple, applicability and workable, implies huge use value.Mechanism involved in the present invention and control system not only improve the production efficiency of enterprise, the human resources reducing enterprise drop into, reduce production cost, and solve product quality under traditional mode of production pattern uneven, be difficult to the problem that ensures, utilize it to produce to provide the gas filling bottle of high accuracy quality requirement, economy and brand benefit significantly, serve great effect to the raising market competitiveness.
Below by reference to the accompanying drawings embodiments of the present invention are described in detail, but the present invention is not limited to described embodiment.For those of ordinary skill in the art, in the scope of principle of the present invention and technological thought, embodiment is carried out to these embodiments and carries out multiple change, amendment, replacement and modification and still fall within the scope of protection of the present invention.
