Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of assembling machinery, in particular to a clamp vertical turnover mechanism. BACKGROUND

[0002] The clamp vertical turnover mechanism is a mechanical device for clamping workpieces at different working angles. It can rotate the clamp in the horizontal and vertical directions through a mechanical structure to clamp workpieces at different working angles. This device is commonly used for processing or detecting workpieces, especially when both the front and back surfaces of the workpiece need to be processed or detected. It can achieve automatic turnover of the workpiece and improve processing or detection efficiency.

[0003] However, when the vertical turnover mechanism turns over the clamp, it is difficult to intuitively determine the turning angle. During use or transportation, the clamp is easily deflected due to the limitations of its own structure, as well as factors such as vibration and impact during processing and transportation, resulting in decreased processing accuracy and construction errors. The clamp may be deflected or have errors, leading to poor quality in the manufacturing or processing process, or even damage to the product. SUMMARY
