Description
Technical field
The present invention relates to a kind of carrier lifting device group mounted welder and its welding method, a kind of carrier lifting device group
Mounted welder.
Background technology
Lifting device is carrier core component, it is responsible for relay cylinder thrust, and side plate is moved up and down and switchs to crank
Curvilinear motion, turn to linear motion by the revolution of arm of force block again, reaches the task that pallet fork is steadily lifted.Prong is directly used in structure
With front apron, guide rail, link assembly hoisting way, the structure of column, door frame, bottom end rail and leg seat is eliminated, therefore is reduced
Bodywork height and center of gravity, make it have framework be unlikely to deform, raising it is steady, compact-sized, light and handy flexible construction feature, market
Have a extensive future.
In traditional assembly welding shaping operation, paid the utmost attention to for work efficiency, get used to hand and take plane positioning operation.This side
Formula, has certain service advantages for small lot Member Welding that is thick and heavy, being not difficult, but for non-thick and heavy accessory, multi-part
Welding fabrication batch jobs and technology-intensive operation just do not match, and can not meet such as connecting rod lifting group in new product
Part hole-hole positions new technical need, because preceding hole use hole positioning but be not completely fixed, metapore no-fix to build as main weldering
Type operating type is connected into, connecting rod serious distortion occurs in assembling.Since connecting rod and front and rear hole seat center are inconsistent, hole pin can not
Penetrate connection.
China Patent Publication No. 103084772B, discloses a kind of frame set mounted welder, can be with according to frame set mounted welder
After frame set is welded, the location division for adjusting movable locating device is allowed between fixed seat change location division with respect to slip
Relative to the position of frame, consequently facilitating the taking-up of frame.But the accuracy of welding is not obviously improved.
The content of the invention
The technical problems to be solved by the invention are the above-mentioned deficiencies overcome in the presence of the prior art, and provide one kind and set
Meter is reasonable, can effectively improve the carrier lifting device group mounted welder and its welding method of product size welding precision.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of carrier lifting device group mounted welder,
