However, an integral welding tire rotating device is absent at present, complex process operation is difficult to complete only through a common positioner, the requirements of welding quality and production efficiency cannot be met, the working strength of operators is high, and the production process is complex and tedious.

SUMMERY OF THE UTILITY MODEL

Welding child for framework, to above-mentioned problem and not enough and construct a rotatory supporting device structure based on the lift stand of both sides, upwards connect a rotatory anchor clamps body and realize can operating the framework and rotate and fix a position wantonly on two directions of vertical and level through a horizontal gyration roof beam.

The utility model aims to design an aim at provides an integral child device that changes, can adjust the frame according to the technology requirement and by the welding station and carry out 360 degrees rotational positioning on vertical, the horizontal direction, reduce frame welding process complexity, improve production efficiency and welding quality.

In order to achieve the design purpose, the framework is formed by fixedly connecting a rotary supporting device between two side lifting upright columns, specifically,

the rotary supporting device is provided with a horizontal rotary beam, a rotary mechanism driven by a motor is arranged in the center of the rotary beam, and the rotary mechanism is upwards connected with a rotary clamp body for supporting and fixing a welded framework;

the top of the lifting upright post is provided with a driving motor, and the transmission belts driven by the motor are vertically arranged downwards along the lifting upright post and are connected to the mounting frames at the two side ends of the rotary beam;

a rotary motor is arranged on the outer side of the end part of the rotary beam, and an output shaft of the rotary motor is fixedly connected to the mounting frame on one side of the rotary beam.

According to the structural scheme, the horizontal rotary beam is driven by the rotary motor at the end part, can drive the rotary clamp body, and drives the welded framework to rotate and position for 360 degrees in the vertical direction through the rotary clamp body.

The rotating mechanism driven by the motor can drive the rotating clamp body and drive the welded framework to rotate and position 360 degrees in the horizontal direction through the rotating clamp body.

Meanwhile, the vertical transmission belt of the lifting upright post can drive the whole rotary beam to be adjusted in vertical height so as to meet the requirement of welding workers in welding operation of a large framework.

In order to enhance the operational flexibility and mechanical strength of each driving motor to the whole rotary beam, a further improvement scheme can be that a vertical mounting disc is respectively arranged at two side ends of the rotary beam, and an output shaft of the rotary motor is fixedly connected to a mounting frame through the vertical mounting disc at one side;

the transmission belts vertically arranged along the lifting upright posts adopt a transmission rack structure, and the racks are meshed and fixed with the mounting disc at the side end of the rotary beam.

The operating stress points of the rotary motor and the lifting motor on the rotary beam can be uniformly dispersed on the mounting disc, so that the connection and transmission rigidity is enhanced.

In addition, the refinement scheme that can also be adopted is that two sides of the rotating mechanism at the center of the rotary beam are fixedly connected with the rotary beam through a rotating driving part mounting table.

The fixing of the rotation mechanism driven by the motor can be further enhanced by the rotation driving unit mounting table.

In order to prevent the welded framework from falling off and shifting when rotating in all directions and angles, a disc-shaped positioner for fixing the welded framework can be arranged at the center of the rotating clamp body, and a plurality of pressing devices are symmetrically arranged on the periphery of the positioner.

In order to facilitate the actual operation of a welder on each welding station of the framework, the whole welding rotary tire can be also provided with a lifting working platform, the platform is provided with a support frame body and an operating platform, a pair of lifting cylinders is arranged on the upper part of the support frame body, and a cylinder shaft is vertically connected to the bottom of the operating platform.

The welder can randomly adjust the vertical height of the working platform according to the process requirement to improve the welding work efficiency.

In summary, the welding tire for the framework has the following advantages:

1. the welding rotating tire is reasonable in structure, the frame to be welded can be controlled by the electric button to rotate and position 360 degrees in the vertical direction and the horizontal direction, and welding workers can complete welding operation on all welding seams of the frame.

2. The integral welding rotary tire can greatly improve the quality and efficiency requirements of welding production, reduce the labor intensity of operators and effectively reduce the complexity of the welding process.
