Description

TECHNICAL FIELD

[0001] The utility model belongs to tooling auxiliary equipment technical field relates to a carbon fiber sheet numerical control processing space positioning device. BACKGROUND

[0002] At present, some domestic enterprises have the ability to process carbon fiber sheets, and through continuous improvement of clamping methods and use of special tools, product quality is also increasingly stable. When the curvature of carbon fiber sheet parts is simple or there is no curvature and the precision requirement is low, the ordinary clamping and positioning process scheme can basically meet the production requirements. However, as the use range of carbon fiber sheet parts gradually expands, the structure of the parts themselves becomes more and more complex, and often there is large double curvature and higher precision requirement, at which time a high-precision positioning method is needed to meet the one-time clamping of the parts for processing.

[0003] At present, the traditional clamping and positioning method is to use a telescopic column clamping method with vacuum suction chuck connected to a numerical control machine tool. This method uses multiple telescopic columns with vacuum suction discs to accurately position complex double curvature parts by stretching to different heights and multi-point suction. After positioning, the parts are processed by numerical control machining to complete the rough and fine machining of the shape and frame of the parts, thereby completing the production of the parts. This type of machining and positioning method has the following disadvantages:

[0004] (1) Although this method can ensure accurate positioning of the parts, there are still local areas that cannot be completely suctioned by the vacuum suction chuck due to the size limitation of the vacuum suction chuck, and the complex structure of the parts often causes incomplete clamping at the sharp corners, corners and edges of the parts, resulting in part shaking during processing and reduced part processing precision. Lightly, it causes the surface to be uneven during processing, and heavily, it causes the part to be cut too much, resulting in part scrap;

[0005] (2) Some places cannot be processed by numerical control machine tools, and often rely on manual processing to ensure that the labor intensity of workers is high and the efficiency is low; the uncertainty of manual operation reduces the product qualification rate and lengthens the entire part processing cycle.
