The present invention relates to technical field of welding equipment, especially a kind of welding process equipment for welding the tank body class containers such as water tank for mixer trucks.
Background technology
Domestic special purpose vehicle industry is of certain scale through development for many years, become the important component part of Domestic Automotive Industry, the kind of special purpose vehicle and quantity along with expanding economy increasing, which includes all kinds of oil tank carrier vehicle, cement bulk car, cement semitrailer, concrete mixer truck etc. comprise the special purpose vehicle of tank body, development and the urban environmental protection construction of the various special purpose vehicle containing tank body are also closely connected, particularly along with in recent years to the increasing of Clean city dynamics, building site and concrete stir in advance and require to be separated, the increase that the demand of trucd mixer will continue, water tank on trucd mixer is again the functional part that must configure of every platform trucd mixer, so the demand of water tank for mixer trucks will increase along with the increase of trucd mixer demand.Water tank for mixer trucks is a functional part, need the water of access cleaning, the water tank meeting pressurized when access water, whether the quality of welding determines water tank and can leak, water tank is an appearance part simultaneously, whether its outward appearance is attractive in appearance, and have impact on the monolithic image of client to vehicle, remote-effects client is to the evaluation of vehicle performance.The welding method of outer sealing such as existing a kind of circular tank little to water tank for mixer trucks etc. is positioned on jig by workpiece, by workman's handmade rotary workpiece when carrying out weld job, while weld with automatic welding gun.There is following deficiency in this solder technology scheme: welding weldquality is out unstable, and appearance of weld is poor, and welding line joint is many, easily leaks, and welding efficiency is very low.
Summary of the invention
The object of this invention is to provide a kind of tank body welding equipment, this welding equipment can solve in prior art the welding quality instability of welding circular tank and existing, and welding line joint is many, easily leaks, the problem that welding efficiency is low.
In order to solve the problem, the technical solution used in the present invention is: this tank body welding equipment comprises the clamping device and elasticity holding device that are oppositely arranged, described clamping device is connected with rotating driving device, the bracket for supporting circular tank is provided with between described clamping device and described elasticity holding device, described circular tank side is provided with welding gun bracing frame, described welding gun bracing frame is provided with automatic welding gun.
In above-mentioned tank body welding equipment and technology scheme, technical scheme can also be more specifically: the side, the same side of described clamping device and described elasticity holding device is provided with a horizontal guide rail, described welding gun bracing frame is installed on one at the uniform velocity in walking mechanism, and described at the uniform velocity walking mechanism is arranged on described horizontal guide rail.
Further, described elasticity holding device comprises elasticity arch bar and spring, and described elasticity arch bar protrudes towards the direction of described clamping device, and one end of described elasticity arch bar is fixed on a column, and described spring is connected between described column and described elasticity arch bar.
Further, described elasticity arch bar is arch band iron.
Further, described clamping device is chuck, and described rotating driving device comprises motor and decelerator, and described motor is in transmission connection by described decelerator and described chuck.
Further, described automatic welding gun is CO2 gun; Described bracket is the roller support that top is provided with two rollers.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, welding efficiency is high; The one end of the clamping device clamping circular tank driven by rotating driving device is set, and at tank body other end elasticity holding device top pressure tank body, thus the Automatic continuous realizing tank body rotates, coordinate the wire feed that automatic welding gun is stable again, effectively ensure that the stability of annular welds, improve welding quality, within one week that has welded tank body, just only have one to two joints;
2, adopt automatic rotary welding, and at the uniform velocity walking mechanism straight line welding, as long as workman has debugged the state of equipment, start just automatically can complete welding, workman aside supervises, and greatly reduces the labour intensity of workman.In addition, owing to being automatic welding, the dependence of high professional qualification welder in welding process can be reduced;
3, being equipped with of arch band iron and spring, improves the reliability of clamping and the stability of rotation in tank body rotation process.
Accompanying drawing explanation
Fig. 1 is the structural representation of this tank body welding equipment.
Fig. 2 is that Fig. 1 is from roller support towards the left view of left projection.
Fig. 3 is the front view of chuck.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Tank body welding equipment shown in Fig. 1 and Fig. 2 mainly comprises pedestal 1, chuck, rotating driving device, elasticity holding device, bracket, at the uniform velocity walking mechanism 7, horizontal guide rail 11 and automatic welder(welding machine) 9, chuck is installed on a supporting seat 12, this supporting seat 12 is fixed on pedestal 1, elasticity holding device is installed on a column 2, this column 2 is also fixed on pedestal 1, elasticity holding device and chuck are oppositely arranged, so that the circular tank 6 that clamping is to be welded, the side, the same side of chuck and elasticity holding device is provided with a horizontal guide rail 11, horizontal guide rail 11 is installed on pole 13, horizontal guide rail 11 parallels with the rotation of chuck, horizontal guide rail 11 is provided with an at the uniform velocity walking mechanism 7, at the uniform velocity walking mechanism 7 is a dolly being provided with road wheel, the actuating unit that ground-engaging wheel is at the uniform velocity walked and the controller controlling actuating unit is provided with in car body, carbody shell is provided with walking switch, welding gun bracing frame 8 is fixed with in the upper end of car body, welding gun bracing frame 8 is provided with automatic welding gun 9, automatic welding gun 9 is positioned at the top of circular tank 6 to be welded, in order to improve the stability that circular tank 6 rotates, keep circular tank 6 to rotate on an axis, between chuck and elasticity holding device, be provided with the bracket for supporting circular tank 6, bracket is the roller support 5 that top is symmetrically arranged with two rollers, the chuck of the present embodiment is scroll chuck 10, the clamping devices such as chuck can be adopted in other embodiment, the center position at scroll chuck 10 back side is installed with rotating shaft, rotating driving device comprises and is installed on motor in supporting seat 12 and decelerator, rotating shaft connects with decelerator, and decelerator is driven by motor, elasticity holding device comprises elasticity arch bar and spring 4, elasticity arch bar is arch band iron 3, arch band iron 3 protrudes towards the direction of scroll chuck 10, one end of arch band iron 3 is fixed on column 2, spring 4 is connected between the free end of arch band iron 3 and column 1, circular tank 6 to be pressed to by arch band iron 3 and to produce grip friction power with the pawl card of scroll chuck 10 by spring 4, and one end arch band iron 3 be fixed on column 2 can ensure there is enough frictional force between circular tank 6 and pawl card.It is worth mentioning that, the automatic welding gun 9 of this tank body welding equipment is CO2 gun.Three pawl card 10-2 of the scroll chuck 10 shown in Fig. 3 are mounted in the T-slot 10-3 of disk 10-1, and pawl card 10-2 can move radially along disk 10-1 in T-slot 10-3, and the position of pawl card 10-2 adjusts according to diameter of work size.
