Description

Technical Field

[0001] The present application relates to the technical field of loading and unloading robots, and specifically to a special fixture for loading and unloading robots. Background Art

[0002] An automated loading and unloading robot is a mechanical device developed on the basis of a loading and unloading mechanism. Initially, it was mainly used to automatically load and unload materials and transport workpieces, completing single-machine automation and production line automation. As its scope of application continues to expand, it is now used to operate tools and complete work, reducing workers' labor intensity, improving working conditions, and increasing production efficiency. Traditional automated loading and unloading devices are scattered small and medium-sized workpiece blanks that are oriented and arranged by an orienting mechanism. The loading and unloading mechanisms then sequentially deliver them to the machine tool or work position and remove the workpieces. In batch mass production, especially when high productivity and short maneuvering hours are required, simple loading and unloading devices are difficult to meet the requirements. Therefore, automated loading and unloading robots were put into operation.

[0003] Currently, the clamping system used by existing loading and unloading robots cannot move and adjust the workpiece during the clamping process. It can only be adjusted when it is re-placed on the platform and clamped again. This wastes time and has poor applicability. Utility Model Content

[0009] Optionally, cylinders are installed on the side walls of the fixed shell and the movable plate facing each other, and the piston ends of the cylinders are connected to support plates.

[0010] By adopting the above technical solution, the cylinder is started, and the cylinder drives the support plate to move in the vertical direction, and the support plate can provide auxiliary support for the workpiece.

[0011] Optionally, a plurality of guide rollers are evenly and equidistantly connected to the upper end of the support plate.

[0013] Optionally, two sliding grooves are symmetrically provided on the upper end of the fixed plate, a slider is slidably connected in the sliding groove, and one end of the slider is connected to the movable plate.
