Problems solved by technology
At present, the workpieces welded by domestic welding robots have certain limitations in application. The disadvantages are: 1. There are many kinds of workpieces and different shapes, and it is impossible to change the posture on a unified platform; 2. The posture of the workpiece needs to be changed manually, which cannot be positioned flexibly; 3. The weight of the workpiece is generally too small to achieve precise positioning of heavy workpieces

Embodiment 1
[0038] Embodiment 1: A welding lintel is clamped between the clamping mechanisms, and a workpiece 16 is fixed on the welding lintel.
Embodiment 2
[0039] Embodiment 2: A movable lintel support frame is clamped between the clamping mechanisms, and a workpiece 16 is fixed on the movable lintel support frame.
Embodiment 3
[0040] Embodiment 3: The mine car coupling frame is clamped between the clamping mechanisms, and the workpiece 16 is fixed on the mine car coupling frame.
[0041] Appropriate workpieces 16 can be directly fixed and clamped between the clamping mechanisms, and some workpieces 16 that are not suitable for direct clamping can also be clamped by using welding lintels, movable lintel support frames, and mine car coupling frames. Welding lintels, movable lintel support frames, and mine car coupling frames are selected based on the shape, size, weight, and different requirements for the welding track of the welding method. Thereby greatly improving the applicability of the present invention.

The invention discloses a free converter for the welding robot. The free converter comprises two work frames which are symmetrically arranged left and right, wherein the work frame comprises a longitudinal lifting sliding table and a transverse clamping sliding table which are vertically arranged in a crossed manner, a servo lifting motor used for driving the transverse clamping sliding table to move downwards is arranged at the top end of the longitudinal lifting sliding table, the servo lifting motors are connected with a single motor module i, the motor modules i of the two servo lifting motors are connected with each other, the synchronous lifting and the accurate asynchronous lifting of the two servo lifting motors are realized, the two motor modules are connected to the same power supply module in a one-to-one mode, the transverse clamping sliding table is provided with a clamping mechanism through a turnover positioner, wherein the clamping mechanism comprises two symmetrically-arranged conical heads, the two conical heads are symmetrically arranged, and the relative spacing is changed by a servo clamping motor to achieve a clamping function.
Description
technical field [0001] The invention relates to the field of welding robots, in particular to a free transformation machine for welding robots. Background technique [0002] The welding robot free positioner is a heavy-duty tooling that automatically cooperates with the robot to change the position. Through the automatic detection system and the precise interpolation positioning of the servo, the position of the workpiece can be changed arbitrarily, so that the welding robot can work smoothly and efficiently. The agency installs a large-scale factory building welding workshop, which cooperates with the detection and use of welding robots. At present, the application of workpieces welded by domestic welding robots has certain limitations. The disadvantages are: 1. There are many types of workpieces and different shapes, and it is impossible to change postures on a unified platform; 2. The postures of workpieces are changed manually and cannot be positioned flexibly; 3. The w...
