Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ground detection equipment, and particularly relates to an automatic overturning device of a special-shaped shell. BACKGROUND

[0002] In the field of mechanical processing, the blank materials of many large and medium-sized special-shaped shells are cast aluminum alloys, which are not only complex in shape and poor in structural rigidity, but also are not designed with any lifting hole. In order to ensure product quality, the special-shaped shells need to be detected and accurately detected in shape during and after the processing of the special-shaped shells. At present, the operation method for detecting the special-shaped shells is to overturn the special-shaped shells by manual operation multiple times and then to measure and detect. This method has the following shortcomings: it is difficult for the detection personnel to observe some key processing positions during measurement and detection, the detection is difficult, the measurement result is affected, the operation is complicated, the risk is high, and the special-shaped shells are easily bumped during the detection process, causing product quality problems.

[0003] Chinese patent CN110053004A discloses an automatic overturning device for shell workpiece processing, which comprises a base, an overturning support, a lifting device, a positioning device, a clamping mechanism, an overturning shaft, a swing oil cylinder, a false-touch prevention sensing locking device and a PLC control system. The lifting device and the positioning device are installed on the base. The positioning device is installed and fixed above the lifting device. The base on both sides of the lifting device and the positioning device is connected with an overturning support. The clamping mechanism is connected with the overturning supports on both sides through an overturning shaft. One of the overturning shafts is connected with the swing oil cylinder. The false-touch prevention sensing locking device is installed on the upper end of the overturning supports. The PLC control system controls the overturning device to perform according to the specified program, realizes the rapid overturning of the shell workpiece, saves a lot of manpower and material resources, avoids the damage of the workpiece and the labor, and improves the processing efficiency of the shell workpiece.

Therefore, a composite device is needed to realize the automatic controllable overturning of the special-shaped shell to replace the manual detection and shape detection of the special-shaped shell without a lifting hole.
