Description

A kind of corrugated plate welding machine

Technical field

The utility model relates to a kind of corrugated plate welder, and the automatic soldering device in a kind of corrugated plate end face slit specifically is provided for the radiatinig corrugated sheet of oil-filled transformer.

Background technology

In oil-filled transformer, the welding of radiatinig corrugated sheet is the production process of one key, and the welding at place, two slits of its corrugated plate end face is topmost welding position.At present, general adopt artificial or the semi-automatic welding mode is welded, its defective is: welding quality and appearance can't guarantee, need to rely on welding person's experience control quality, and percent defective is higher; Welding person's labour intensity is big, inefficiency; Welding person is closely welding production for a long time, sucks the smog pernicious gas that solder flux produces, and is unfavorable to labour protection and environmental protection.

In order to solve the problems of the technologies described above, people have designed automatic soldering device.Patent application document [application number: 200810122621.1] discloses a kind of corrugated plate welding machine.This corrugated plate welding machine comprises frame, be horizontally set on conveying device on the frame, be provided with welder above the conveying device, be provided with one be used for fixing corrugated plate and can be with the moving positioning device of corrugated plate translation one segment distance in welder, welder comprises at least one welding gun and the welding gun elevating mechanism that weldering is robbed is housed that the welding gun elevating mechanism links to each other with frame and can drive the welding gun in the vertical direction and moves.This corrugated plate welding machine can effectively be enhanced productivity, and reduces hand labor intensity; Welding quality is good, and percent defective is low, effectively reduces the corrugated plating production cost; Can also weld the corrugated plate of different size, applied widely.But the clamping device that is used for fixing corrugated plate in this corrugated plate welding machine only adopts simple clamping mechanism, and this mechanism can not compress the location up and down to corrugated plate well; In addition, corrugated plate can produce thermal expansion in welding, need carry out left and right sides clamping to the corrugated plate welding end surface and could guarantee welding quality.

Summary of the invention

In order to solve above-mentioned deficiency, the utility model provides a kind of compact conformation, can guarantee welding quality, applied widely, can weld about corrugated plate two end face slits, production efficiency height, full-automatic corrugated plate welding machine that hand labor intensity is low simultaneously.This bonding machine by frame, be arranged on work handling device on the frame, be symmetricly set on welder, welding gun water-cooling apparatus, air inducing dust arrester and six most of compositions of automatic lubrication oil injection system of top, the work handling device left and right sides, each welder bottom is fixing left and right sides internal thread piece respectively, be respectively the externally threaded screw rod in the left and right sides with one two end and constitute the screw thread transmission, and do in opposite directions or from mobile by two horizontal guide rails on the frame, to regulate the distance between two welders, be adapted to the welding of different in width corrugated plate.

But the mobile frame case of translation is installed in the inside of welder, and its translation mechanism can be the cylinder piston rod structure, also can be screw structure, can make carry or the translation of giving up the throne on the guide rail in being arranged at welder; Move two simultaneously a welding gun lowering or hoisting gear respectively is installed in the frame case, it both can be a lead screw transmission, also can be the rack-and-pinion transmission.

Be installed in the welder and on the mobile frame case a horizontally disposed corrugated plate end face clamping device be installed respectively also, it is the six-bar mechanism of a symmetry, and its six roots of sensation pole links with revolute pair respectively, and slide block is a drive rod, with cylinder or the lead screw transmission source that is used as power.

Corrugated plate hold down gag up and down is installed at the top of welder, and it both can be the cylinder piston rod structure, also can be lead screw transmission, and the short transverse at corrugated plate is provided with a height and position sensor simultaneously.

In addition, also be provided with the automatic lubrication oil injection system, comprise lubricated electrodynamic pump, oil circuit distributor, three-way device and each road binders pipe etc., in order to automatically, regularly all of oily corrugated plate welding machine have the position of relative motion, comprise each revolute pair, moving sets and screw pair.

The work handling device that is arranged on the frame adopts the motor variable-frequency speed-regulating drive sprocket chain and the roller-way kind of drive.

The advantage of this corrugated plate welding machine is: 1. can regulate the corrugated plate of different in width, height, to be adapted to the welding requirements of various different size corrugated plates; 2. can locate up and down corrugated plate well and compress, simultaneously corrugated plate biend slit be clamped simultaneously and welds; 3. compact integral structure, the whole operation process is automatically finished, the production efficiency height, hand labor intensity is low, and security is good; 4. adopt the air inducing dust arrester, reduce human body harm, the protection environment.5. weld appearance is neatly evenly attractive in appearance, and welding quality is good.
