Abstract
The utility model discloses a multi-point synchronous intermittent girth welding device, which comprises a moving pressure head, welding guns, vertical columns, expansion pieces, a base, a positioning disk and a gland, wherein the positioning disk capable of rotating around a shaft serving as a center is vertically arranged in the middle of the base; a seam allowance is upwards formed on the positioning disk and used for mounting a workpiece to be welded; the moving pressure head is a vertically downward pressing device positioned on the positioning disk; the downward end of the moving pressure head, from which a piston rod is exposed, is in floating connection with the gland in an unlimited rotation manner; 2 to 4 vertical columns are uniformly distributed around the workpiece on the base; and the expansion pieces are locked on the vertical columns opposite to welding positions. The welding guns are controlled by an automatic welding machine to automatically and discontinuously travel straightly in a fixed point reciprocating manner along with the expansion pieces and matched with the workpiece rotating along with the positioning disk, so that intermittent girth joints are formed naturally. Due to maneuvering multi-point synchronous fixed-point welding, manmade influence is avoided, the welding production efficiency is high, and the quality is stable. The multi-point synchronous intermittent girth welding device is particularly suitable for large-batch production and assortment.
Description
Technical field
The utility model relates to a kind of welder, and specifically, the utility model relates to a kind of multiple spot and is interrupted the boxing device synchronously.
Background technology
The civil LPG steel cylinder is a kind of vertically-arranged low capacity pressure vessel, and its end socket top, bottle two ends is respectively equipped with external handle and base, and it is safe in utilization that the welding quality of these annexes and bottle end socket is related to liquefied petroleum gas steel cylinder.Uncomplicated because of the annex Welding Structure, the steel cylinder manufacturing industry generally uses skilled welder to implement the manual welding of fixing a point in the production scene, and manual welding can reach the welding quality of expectation fully under the normal condition.Civil LPG steel cylinder production in the present age is that streamline is produced in enormous quantities, and the welder repeats to weld operation on fixed point work position, and lasting mechanical type action labour intensity is big.In addition, annex and bottle be connected to intermittent weld, the frequent changes starting the arc, welding and the action of receipts arc are prone to cause and do not produce some misoperations unavoidably by operation fatigue.Thus, have the welder of normal physical efficiency to be difficult on this post, accomplish the welding quality self-consistentency, this post welding quality is unstable, has become the bottleneck problem that restriction steel cylinder manufacturing industry production efficiency and economic benefit promote.
The utility model content
The utility model is primarily aimed at the steel cylinder manufacturing industry, and the quality problem of unstable proposes a kind of multiple spot simple and reasonable for structure and is interrupted the boxing device synchronously when civilian oil liquefied gas steel cylinder annex welds.This device is through positioning and clamping, and the production efficiency height is not only welded in the synchronous automatic discontinuous welding of multiple spot, and welding quality stable.
The utility model is realized technical goal through following technical proposals.
Multiple spot is interrupted the boxing device synchronously, and it comprises dynamic head, welding gun, column, expansion bend, base, positioning disk and gland.Its improvements are: vertically install with the axle at said base middle part is the positioning disk of center rotation, and positioning disk is provided with the seam with installation workpiece to be positioned towards the upper surface.Said dynamic head is the vertical descending hold down gag that is positioned on the positioning disk, and both are coaxial, exposes tailpiece of the piston rod down at dynamic head and does not limit the unsteady of rotation with gland and be connected.Be uniformly distributed with 2～4 root posts around workpiece on the said seating plane, corresponding welding position locking expansion bend on column, controlled welding gun is back and forth kept straight on the expansion bend fixed point is interrupted.
In the said structure, expansion bend is a kind of craspedodrome mechanism of step motor control.
The utility model compared with prior art has following good effect:
1, location and clamping structure are simple, and the workpiece installation site is accurate, are convenient to the fixed point welding;
2, intermittently craspedodrome is to welding the position automatically with expansion bend for controlled welding gun, and in the interrupted welding of the workpiece that rotates with positioning disk place to be welded enforcement, formation is interrupted girth joint naturally;
3, motor-driven multiple spot connects with the one-step site discontinuous welding, does not receive man's activity, and welding production efficiency is high, steady quality.
Description of drawings
Fig. 1 is the utility model structural representation, expansion bend retraction among the figure, and welding gun leaves the welding position.
The specific embodiment
According to accompanying drawing and combine embodiment, the utility model is described further below.
Shown in Figure 1 is that the multiple spot that welds civil LPG steel cylinder handle embodiment is interrupted the boxing device synchronously, and it comprises dynamic head 1, welding gun 2, column 3, expansion bend 4, base 5, positioning disk 6 and gland 7.Vertically install with the axle at said base 5 middle parts is the positioning disk 6 of center rotation, and positioning disk 6 is provided with positioning spigot towards the upper surface.Workpiece is bottle top end socket 8 and the handle that is connected 9.Workpiece end socket 8 left-hand threads are on the positioning spigot of positioning disk 6 during installation, and workpiece handle 9 to be connected is placed at end socket 8 tops.Said dynamic head 1 is the vertical descending hold down gag that is positioned on the positioning disk 6, and both are coaxial, exposes tailpiece of the piston rod down at dynamic head 1 and float to connect gland 7, and this connection can realize both servo-actuateds of going up and down, and does not limit gland 7 relative dynamic heads 1 and rotates.When gland 7 presses down workpiece,, guarantee that the workpiece installation site is stable promptly with positioning disk 6 rotations.5 of said bases are gone up around workpiece and are uniformly distributed with 2～4 root posts 3, two root posts 3 about being provided with in the present embodiment.Corresponding welding position locking expansion bend 4 on column 3, expansion bend 4 is craspedodrome mechanisms of a kind of step motor control in the present embodiment, expansion bend 4 is back and forth kept straight on by automatic welder(welding machine) control welding gun 2 fixed points.Expansion bend 4 is inwardly kept straight on welding gun 2 is delivered to the welding position during welding, forms girth joint in the place to be welded welding with positioning disk 6 rotational workpieces, and to predetermined girth joint discontinuities, expansion bend 4 outwards bounces back, and drives welding gun 2 and leaves the welding position, realizes that girth joint is interrupted.Put and the weld seam discontinuities as long as welding position is revolved in the arrival setting, expansion bend 4 repeats above-mentioned action and drives welding gun 2 weldings or stop welding.
The utility model is back and forth kept straight on expansion bend 4 automatic pointings are interrupted by automatic welder(welding machine) control welding gun 2, cooperates with the workpiece that rotates with positioning disk 6, forms naturally and is interrupted girth joint.Owing to be that motor-driven multiple spot welds with one-step site, do not receive man's activity, welding production efficiency is high, steady quality.
The utility model is also applicable to the welding of civil LPG steel cylinder base and valve seat.
