The automatic circumferential welding machine for jacks is characterized by comprising an instrument lathe, and a three-jaw chuck, a tailstock, a speed adjusting motor, a transmission mechanism, a carbon dioxide welder welding gun, cross flat tongs, a linear guide rail and a cylinder are in threaded connection with a spindle of a spindle box of the instrument lathe. The spindle of the spindle box of the instrument lathe is connected with the speed adjusting motor through the transmission mechanism, a vertical column is vertically and fixedly connected to a tabletop between the tailstock and the three-jaw chuck of the instrument lathe, the linear guide rail is fixedly connected to the vertical column and connected with a cylinder piston, and the carbon dioxide welder welding gun is fastened by the cross flat tongs which are fixedly connected onto the linear guide rail. The automatic circumferential welding machine for jacks has the advantages that labor is relieved to a great extent, operating efficiency is quickly improved, production efficiency is improved by 40% as compared with that in the past, and welding quality is stably improved.
Description
Technical field
The utility model belongs to the gas shielded welding auxiliary equipment, relates in particular to a kind of jack automatic circular welding machine.
Background technology
Jack comprises overcoat, oil cylinder and three major parts of base, need to above-mentioned three weld parts be become whole through three road weld seams.The technology condition of integral solder requires very high.Bear the pressure requirement and reach 8Kg/mm
2, weld seam is attractive in appearance, and normal pressure is without leakage.At present, welding procedure is to adopt carbon dioxide gas shielded welding machine to operate by hand.Concrete behaviour's method: base is placed on horizontally rotates on the workbench, existing oil cylinder is contained in the annular groove of base, press-fit; Operator's hand torch welds oil cylinder and base; Putting overcoat uses carbon dioxide semiauto-welder to cooperate the twice weld seam that solder mask and base and overcoat and oil cylinder are suitable for reading with rotary table again.Because adopt manual operations, welding quality is unstable, weld seam is inhomogeneous, the defectives such as welding bead often occur departing from, and is very high to operating personnel's solder technology requirement; Hand labor intensity is large, and homemade rotary table hold down gag coaxiality deviation is large, easily departs from during work, affects welding quality, therefore inefficiency.Demand developing a kind of assurance welding quality in the industry urgently, the mechanical welding equipment of energy instead of manual welding.
The utility model content
The utility model is in order to overcome deficiency of the prior art, to provide a kind of and can instead of manual weld in order to increase work efficiency, alleviate the jack automatic circular welding machine of operator's labour intensity, guaranteeing welding quality.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of jack automatic circular welding machine, it is characterized in that: comprise instrument lathe, the main shaft of instrument lathe spindle case is bolted with scroll chuck, rear tailstock, buncher and transmission mechanism, the carbon dioxide arc welding machine welding gun, cross-shaped flat tongs, line slideway and cylinder, the main shaft of described instrument lathe spindle case is connected with buncher by transmission mechanism, vertical affixed column on the table top between described instrument lathe scroll chuck and the rear tailstock, be connected with line slideway on the described column, described line slideway is connected with cylinder piston, affixed cross-shaped flat tongs on the described line slideway, the fastening carbon dioxide arc welding machine welding gun of described cross-shaped flat tongs.
The described scroll chuck positioning fixture that has been installed, rear tailstock is provided with live center.
Described transmission mechanism is chain gear transmission or belt transmission, and the workpiece rotational velocity is 13～15 seconds/week.
Beneficial effect: alleviated to a great extent the labour, and operating efficiency is improved fast.The production efficiency of comparing has before this improved 40%, and welding quality has obtained stable raising.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the side view of Fig. 1.
Among the figure: 1, main spindle box, 2, scroll chuck, 3, positioning fixture, 4, cross-shaped flat tongs, 5, the carbon dioxide arc welding machine welding gun, 6, line slideway, 7, column, 8, rear tailstock, 9, the lathe table top, 10, buncher, 11, minor sprocket, 12, cylinder, 13, chain, 14, hinge wheel, 15, live center.
The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that foundation the utility model provides: see accompanying drawing for details, a kind of jack automatic circular welding machine, comprise instrument lathe, the main shaft of instrument lathe spindle case 1 is bolted with scroll chuck 2, rear tailstock 8, buncher 10 and transmission mechanism, carbon dioxide arc welding machine welding gun 5, cross-shaped flat tongs 4, line slideway 6 and cylinder 12, the main shaft of described instrument lathe spindle case is connected with buncher by transmission mechanism, vertical affixed column 7 on the lathe table top 9 between described instrument lathe scroll chuck and the rear tailstock, be connected with line slideway on the described column, described line slideway is connected with cylinder piston, affixed cross-shaped flat tongs on the described line slideway, the fastening carbon dioxide arc welding machine welding gun of described cross-shaped flat tongs.The described scroll chuck positioning fixture 3 that has been installed, rear tailstock is provided with live center 15.Described transmission mechanism is chain gear transmission, comprises hinge wheel 14 and minor sprocket 11 and chain 13 or belt transmission, and the workpiece rotational velocity is 13～15 seconds/week.
The course of work:
Hydraulic jack need to have the welding of three road circumferential welds, generally can adopt two jack automatic circular welding machine continuous productive processes, and First only welds the weld seam between oil cylinder and the base; Second be used for welding oil cylinder and overcoat between suitable for reading weld seam and the weld seam between overcoat and the base.Because the specification of hydraulic jack is more or less the same, only can realize the welding of all size hydraulic jack with cross-shaped flat tongs fine setting welding torch position.
During welding,
1. first oil cylinder and base are laid on the positioning fixture of scroll chuck, withstood with rear tailstock live centre again;
2. start the source of welding current, welding gun reaches the welding position of appointment automatically;
3. protective gas is pre-front 0.5 second, the welding beginning, and welding work pieces is simultaneously by the good rotating speed rotation of debugging;
4. rotational velocity and speed of welding are debugged, the workpiece rotation: 13～15 seconds/week.
Operating path:
Workpiece location, welding gun reset, welding begins, welding gun is return, workpiece is fetched.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment does.
