Abstract
The invention discloses a multipoint synchronous intermittent girth welding device which comprises a dynamic head, a welding gun, stand columns, expansion pieces, a base, a locating plate and a gland. The locating plate is vertically installed in the middle of the base and rotates with an axis as a center, and a spigot is upwards arranged on the locating plate for installation of a workpiece to be welded. The dynamic head is a vertical down-pressing device located above the locating plate, the downward end, where a piston rod is exposed, of the dynamic head is connected with the gland in a floating mode, and rotation of the dynamic head is not limited by the connection. 2-4 stand columns are evenly distributed around the workpiece on the base, and the expansion pieces are locked on the portions, corresponding to welding positions, on the stand columns. The welding gun is controlled by an automatic welder to automatically fix points, move straight intermittently in a reciprocating mode along with the expansion pieces and be matched with the workpiece rotating along with the locating plate, and an intermittent girth joint is formed naturally. Due to the fact that the workpiece is flexibly welded at fixed points in a multipoint and synchronous mode, welding is not artificially affected, production efficiency of the welding is high, the quality is stable, and the multipoint synchronous intermittent girth welding device is particularly suitable for being matched with mass production.
Description
Technical field
The present invention relates to a kind of welder, specifically, the present invention relates to a kind of Multipoint synchronous and be interrupted the boxing device.
Background technology
Civil LPG 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 the welding quality of these annexes and bottle end socket is related to liquefied petroleum gas steel cylinder and uses safety.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 normal circumstances.Civil LPG cylinder production in the present age is that streamline is produced in enormous quantities, and the welder repeats the welding operation on the work position of fixing a point, and lasting mechanical type action labour intensity is large.In addition, annex and bottle be connected to intermittent weld, the frequent changes starting the arc, welding and the action of receipts arc easily cause and do not produce unavoidably some misoperations by operation fatigue.Thus, have the welder of normal physical efficiency to be difficult to accomplish the welding quality self-consistentency on this post, this post welding quality is unstable, has become the bottleneck problem that restriction steel cylinder manufacturing efficiency and economic benefit promote.
Summary of the invention
The present invention is mainly for the steel cylinder manufacturing industry, and the unsettled problem of quality, propose a kind of Multipoint synchronous simple and reasonable for structure and be interrupted the boxing device when civilian oil liquefied gas steel cylinder annex welding.This device is by positioning and clamping, and the automatic discontinuous welding of Multipoint synchronous is not only welded production efficiency high, and welding quality stable.
The present invention is achieved through the following technical solutions technical goal.
Multipoint synchronous is interrupted the boxing device, and it comprises dynamic head, welding gun, column, expansion bend, base, positioning disk and gland.Its improvements are: the positioning disk that in the middle part of described base, at right angle setting rotates centered by axle, positioning disk is provided with the seam with installation workpiece to be positioned towards the upper surface.Described dynamic head is the vertical descending hold down gag that is positioned on positioning disk, and both are coaxial, exposes tailpiece of the piston rod down and gland is made the not floating connection of restricting rotation at dynamic head.On described seating plane, around uniform 2～4 root posts of workpiece, expansion bend is locked in corresponding welding position on column, and controlled welding gun is back and forth kept straight on the expansion bend fixed point is interrupted.
In said structure, expansion bend is a kind of craspedodrome mechanism of step motor control.
The present invention compared with prior art has following good effect:
1, location and clamping structure are simple, and the workpiece installation site is accurate, is convenient to the welding of fixing a point;
2, controlled welding gun is intermittently kept straight on to the welding position automatically with expansion bend, is intermittently welding with the place to be welded enforcement of the workpiece of positioning disk rotation, and self-assembling formation is interrupted girth joint;
3, the interrupted welding of motor-driven Multipoint synchronous fixed point is not subjected to man's activity, and welding production efficiency is high, steady quality.
Description of drawings
Fig. 1 is structural representation of the present invention, and expansion bend retraction in figure, welding gun leave the welding position.
The specific embodiment
The below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
Shown in Figure 1 is the Multipoint synchronous interruption boxing device of welding civil LPG cylinder handle embodiment, and it comprises dynamic head 1, welding gun 2, column 3, expansion bend 4, base 5, positioning disk 6 and gland 7.The positioning disk 6 that described base 5 middle part at right angle settings rotate centered by axle, positioning disk 6 is provided with positioning spigot towards the upper surface.Workpiece is bottle top end socket 8 and the handle 9 that is connected.During installation workpiece end socket 8 left-hand threads are on the positioning spigot of positioning disk 6, and workpiece handles 9 to be connected are placed at end socket 8 tops.Described dynamic head 1 is the vertical descending hold down gag that is positioned on positioning disk 6, and both are coaxial, exposes tailpiece of the piston rod floating connection gland 7 down at dynamic head 1, and this connection can realize that both liftings are servo-actuated, does not limit relative dynamic head 1 rotation of gland 7.When gland 7 presses down workpiece, namely with positioning disk 6 rotation, guarantee that the workpiece installation site is stable.5 of described bases are upper around uniform 2～4 root posts 3 of workpiece, are provided with left and right two root posts 3 in the present embodiment.Corresponding welding position locking expansion bend 4 on column 3, in the present embodiment, expansion bend 4 is craspedodrome mechanisms of a kind of step motor control, expansion bend 4 is controlled welding gun 2 fixed points by automatic welder(welding machine) and is back and forth kept straight on.During welding, expansion bend 4 is inwardly kept straight on welding gun 2 is delivered to the welding position, 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 bounce back, drives welding gun 2 and leaves the welding position, realizes the girth joint interruption.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 present invention controls welding gun 2 by automatic welder(welding machine) and back and forth keeps straight on expansion bend 4 automatic pointings are interrupted, coordinates with the workpiece that rotates with positioning disk 6, and self-assembling formation is interrupted girth joint.Owing to being the welding of motor-driven Multipoint synchronous fixed point, be not subjected to man's activity, welding production efficiency is high, steady quality.
The present invention is also applicable to the welding of civil LPG cylinder base and valve seat.
