Description

Technical Field

[0001] The utility model relates to the technical field of lifting mechanical equipment, in particular to a novel lifting and rotating integrated mechanical device. Background Art

[0002] The surface of special-shaped products needs to be processed. Due to the large size and height of special-shaped products, manual labor is unable to reach the top of the products, and multi-sided processing is required. Therefore, during the production process, the products need to be lifted and rotated to meet the processing requirements of various parts. The existing technology usually uses a winch to lift, rotate and position the workpiece.

[0003] The existing technology has some disadvantages: (1) the winch is large in size and occupies a large area, the lifting speed is slow and the efficiency is low when in use, and the noise is loud during operation;

[0004] (2) The positioning accuracy of the winch is not enough, the repeated positioning error is large, the error can reach more than ±5mm, and it is unstable;

[0005] (3) There are great safety hazards in using a winch. It uses a steel cable and a hook to lift the workpiece. Since the steel cable is flexible, there is shaking when lifting the rotating workpiece, which will cause personnel safety problems and the workpiece may collide with other objects, causing damage to the workpiece or other objects.

[0006] To this end, we propose a new integrated lifting and rotating mechanical device. Utility Model Content

[0007] The main purpose of the utility model is to provide a new type of lifting and rotating integrated mechanical device, which adopts PLC-controlled high-precision servo synchronous motor as power drive, can automatically lift and rotate, and has high precision and high speed. The racks and gears have the characteristics of high transmission efficiency, strong bearing capacity, high speed and low noise. The stability of the lifting and rotating integrated mechanical device can be improved through the design of linear slide rails. The design of rotating servo motor components and RV reducers brings about the effect of high-precision positioning, which can effectively solve the problems in the background technology.

[0010] By adopting the above technical solution, the cylinder pushes the limit pin assembly toward the mounting frame through the piston rod, and the limit pin assembly is engaged with the limit block, so as to limit the position of the lifting workbench. The sensor detection piece rises and falls with the frame. When the sensor detection piece contacts the limit sensor, the limit sensor sends a limit signal, and the equipment alarms and stops running to prevent overtravel and ensure safe production.
