Description
Technical Field
The utility model discloses a belong to large-scale part positioner lifting force balance technical field, in particular to hull positioner lifting screw power balance weight device.
Background
The positioner is a special welding auxiliary device and is suitable for welding deflection of rotation/lifting work so as to obtain an ideal processing position and welding speed. The automatic welding machine can be used in cooperation with an operating machine and a welding machine to form an automatic welding center, and is widely applied to workpiece deflection during automatic welding operation.
The large-scale ship welding positioner generally comprises a workbench lifting mechanism and a position changing mechanism, and a welded ship body fixed on the workbench can achieve required welding and assembly angles through the lifting of the workbench. The core component of the device needs frequent lifting and displacement operations in the manufacturing process. Because the work piece that bears is very big and heavy usually, the long-time work of lift in-process motor lead screw is in big load operating mode to and factors such as installation misuse, maintenance untimely cause its life to reduce very easily, appear the trouble such as card death, fall.
Therefore, how to unload the lifting force of the positioner, the load of the screw lifting mechanism is reduced, and the reliability of production and the service life are ensured to draw wide attention.
Disclosure of Invention
In order to solve the problem of balance of lifting force of a large-scale part welding positioner, the high reliability of a lifting screw rod mechanism of the positioner is realized. The patent of the utility model provides a machine of shifting lift lead screw power balance weight device utilizes hydraulic cylinder's auxiliary stay effect, and the guarantee machine of shifting bears less effort all the time at lift in-process lead screw, improves the security of system, the development of guarantee navigation career.
In order to achieve the purpose, the utility model provides a positioner elevating screw power balance weight device includes backing plate, balanced pneumatic cylinder, stand, hinge pivot, lift platform, supporting roller, buffer spring, the pivot and the elevating screw mounting panel shift.
The left and right 2 balance hydraulic cylinders are arranged on the base plate, and the extension rod of each balance hydraulic cylinder is fixed on the stand column through a hinge rotating shaft.
The stand with lift platform welding as an organic whole, the supporting roller links to each other with lift platform through the pivot that shifts.
The welded workpiece is placed on the roller, the buffer spring balances the force of the workpiece, and the roller and the mounting platform of the roller can rotate around the deflection rotating shaft, so that the position self-adaptive adjustment of the workpiece is realized.
The whole lifting platform is connected with the screw rod lifting device through the lifting screw rod mounting plate, the screw rod mechanism moves up and down to drive the whole lifting platform and the upper part of the whole lifting platform to lift together, the stress of the screw rod is detected, and the hydraulic cylinder stretches to realize unloading of the stress of the screw rod.
The utility model provides a positioner elevating screw power balance weight device increases positioner life for realizing the uninstallation of positioner elevating screw mechanism, improves the machining precision by welded workpiece.
