High-reliability and high-efficiency multi-Z-pin pressing-in and cutting-off mechanism

Abstract

The invention discloses a high-reliability and high-efficiency multi-Z-pin pressing-in and cutting-off mechanism. The mechanism can be used for realizing pressing-in and cutting-off of a foam carrierin a Z-pin transition implantation process, and can solve the technical problems of poor implantation precision, low reliability and low efficiency in an existing foam pre-implant preparation equipment technology. The mechanism is characterized in that the pressing-in and cutting-off mechanism can be arranged in a gantry type frame structure, stays at any position in a plane under driving of two vertical feeding mechanisms in the same plane, and is composed of a feeding mechanism, a pressing-in feeding mechanism and a pressing cutting mechanism; and a diamond grinding wheel in the pressing cutting mechanism can cut off multiple Z-pins at the same time in one-time reciprocating motion, and the reliability of cutting-off and pressing-in actions is improved through a pressing device. According to the mechanism, by means of the machining mode that the Z-pins are pressed in the foam carrier in two times through the mechanism, high-reliability and high-efficiency automatic pressing-in and cutting-off for the multiple Z-pins are achieved.

Description

technical field [0001] The invention relates to a high-reliability and high-efficiency multi-Z-pin pressing and cutting mechanism, especially for realizing high-precision, high-reliability and high-efficiency pressing of foam carriers in the process of Z-pin transition implantation. in and out. Background technique [0002] Z-pin technology refers to the process of embedding cured short fiber rods directly in the prepreg of the laminate by referring to the discontinuous stitching method in the stitching composite material technology, and then curing the prepreg to form a laminate. The Z-pin foam pre-implant preparation technology involved uses digital control technology to implant Z-pins with a diameter range of 0.2-1mm into the transitional foam carrier according to a certain distribution law, requiring precise control of the angle of implantation , depth and position. Regarding foam pre-implant preparation equipment technology, the currently known technology is to use tw...

Problems solved by technology

[0003] In order to solve the technical problems of poor implantation accuracy, low reliability and low efficiency in the current foam pre-implant preparation technology, the present invention provides a high-reliability and high-efficiency multiple Z-pin pressing and cutting mechanism, which is A feed mechanism with a vertical linear axis is used to drive the press-in head assembly to press the delivered and clamped Z-pin into the foam carrier to half of the required depth. The root Z-pin is cut off at one time, the press-in head assembly is lifted and moved to the next station, and the same press-in action as the first time is performed again, and the Z-pin that has been cut off for the first time is used on the bottom surface of the guide block. Carry out the second press-in, so that the Z-pin implanted in the foam carrier reaches the final required press-in depth, and complete the complete press-in of a group of Z-pins
