Embodiment Construction

[0041] Such as figure 1 As shown, the multi-layer carbon cloth sewing device includes the main shaft (107) of the acupuncture mechanism (109) for pre-punching and sewing needle planting, driven by the stepper motor 1 (100) to drive the pulley set (101-1 -2) to drive the main shaft to rotate, and the rotation simultaneously drives the two eccentric wheels (105-1-2) to reciprocate up and down, the two are connected by keys, and the two eccentric wheels (105-1-2) respectively drive There are connecting rod 1 (104) and connecting rod 2 (106), the connecting rods are connected with the needle bars, one is the needle-planting needle bar (111), the other is the pre-punching needle bar (112), and drives the two needle bars Reciprocating up and down, the phase difference between the two is 90 degrees, the needle planting needle (113) is provided on the needle planting needle bar (111), and the pre-punching needle (114) is provided on the pre-punching needle bar (112). The acupuncture...

Abstract

The invention discloses a multilayer carbon cloth stitching device which comprises an acupuncture mechanism for conducting pre-acupuncture and stitching and needling, a latching mechanism, a horizontal workbench for clamping carbon cloth and a control system. A main shaft of the acupuncture mechanism is driven by a stepper motor and drives two eccentric wheels to rotate, the eccentric wheels drive a connection rod, the connection rod is connected with needle rods, one of the needle rods is a pre-acupuncture needle rod, the other one is a needling needle rod, and the two needle rods conduct reciprocating movement under the drive of the stepper motor; a main camshaft of the latching mechanism is connected with the stepper motor, the main camshaft is provided with two cams, and the main camshaft drives a bearded needle on a subsidiary camshaft to conduct reciprocating swing and axial reciprocating movement and conducts synchronous rotation with the acupuncture mechanism; the workbench is composed of an X-direction moving platform and a Y-direction moving platform, and the stepper motor is arranged on the workbench so as to achieve movement of a cloth containing supporting plate. By means of the pre-acupuncture, friction generated when carbon yarn penetrates through the carbon cloth is reduced, damage to the carbon yarn is lowered, and stitching of the multilayer carbon cloth is achieved.

Description

technical field [0001] The invention relates to a multi-layer carbon cloth sewing device for forming a carbon fiber three-dimensional fabric. Background technique [0002] Three-dimensional fabric is the fiber reinforced structure with the best performance developed in the past 40 years, and it is mainly used in aviation, aerospace, automobile, medical and new technology fields. Multi-layer carbon cloth stitching technology is a forming technology of three-dimensional fabrics. The process uses pre-cut square carbon cloth multi-layer stacked and flattened, and then placed on the carbon cloth placement platform of the horizontal workbench holding the carbon cloth for pre-stitching. The acupuncture mechanism for suturing and planting needles drives the two needle bars to reciprocate, and the locking mechanism performs locking after the yarn-drawing needle passes through the carbon cloth. The movement of the horizontal table holding the carbon cloth can precisely control the si...
