Abstract

The utility model provides a moveable welding position changing device, comprising a head hoisting frame and a tail hoisting frame. The bases of the head hoisting frame and the tail hoisting frame are separately provided with an elevating screw and a lifting table. The top end of the hoisting frame is provided with a hoisting drive motor which forms a transmission pair with the elevating screw to control the lifting of the lifting table. Caster wheels are fixed on the bottom of each base through screw lifting rods, and a rotation driving motor apparatus is arranged on the lifting table. One end of a tooling clamp device forms a kinematic pair with a drive electric mechanism through a speed reducer, and the other end is connected with the lifting table of the tail hoisting frame to form a working platform. The utility model adopts the head and tail separation-typed structure, and the head and the tail all can move to make the entire position changing device have convenient and flexible movement and simple and easy installation and tooling; simultaneously, the tooling with different lengths can be arranged on the welding position changing device when moving to enhance the application scope.

Description

Portable welding displacement device

Technical field

The utility model is the improvement to existing positioner, discloses a kind of portable welding displacement device, belongs to railroad car bodywork structure welder technical field.

Background technology

At present, the positioner in railroad car bodywork mechanism welding process is a head tailstock integral type connected mode, and fixes with ground, can not move flexibly and install,, the frock complexity is installed the workpiece bad adaptability, the labour intensity height has influenced operating efficiency, has increased production cost.

Summary of the invention

The utility model discloses a kind of portable welding displacement device, overcome existing head tailstock integral type positioner and moved inconvenience, the shortcoming of workpiece bad adaptability.

Technical solution of the present utility model is as follows: constitute portable welding displacement device by head crane and tail crane, wherein, be respectively equipped with elevating screw and lifting platform on the base of head crane and tail crane, the top of crane is provided with the lifting drive motors, constitute transmission with elevating screw, rising and falling of control lifting platform, castor is fixed on the bottom of base separately by the spiral lifting bar, two cranes and ground are fixing, can move with base, the rotary drive motor device is on hoistable platform, Work fixture device one end constitutes kinematic pair by decelerator and drive motors, the lifting platform of the other end and tail crane connects and composes operating platform, can turn round 360 angles along trunnion axis.

Good effect of the present utility model is: adopt head, tail separate type, head, tail are all removable, make whole displacement device conveniently moving flexibly, that frock is installed is simply easy, the frock that on the welding displacement device different length can be installed when mobile is used the scope of application and is improved greatly simultaneously.
