A winding and positioning tool for pre-impregnated glass roving tape

Abstract

The invention discloses a winding and positioning tool for preimpregnated glass roving tape, which comprises a wall plate (2) erected on a base (1). ) and the wall plate (2) keep a rolling fit, the lower part is provided with a screw (7), one end of the two pressure plates (5, 6) is installed on the shoulder screw (3), and the other end is installed on the handle (4), to be wound The parts of the pre-impregnated glass roving tape pass through the shoulder screw (3) and the handle (4), and are fixedly placed between the two pressing plates (5, 6), and are held by the two pressing plates (5, 6). Clamping, two opposite pressure plates (12, 13) are installed on the screw rod (7), a limit block (9) is arranged between the wall plate (2) and the pressure plate, and the pre-impregnated glass roving tape (14) The charging tray passes the screw rod (7) and is installed between the two pressure plates (12,13). The tooling of the present invention is rotated and wound in the vertical direction, which can ensure uniform force application and no deviation in the direction. The width of the prepreg glass roving tape during the winding process is uniform and the thickness is consistent; the operation is simple, saving manpower and winding time .

Description

technical field [0001] The invention belongs to the technical field of composite material molding, and in particular relates to a winding and positioning tool for a prepreg glass roving tape. Background technique [0002] At present, the molding process of the composite girder winding parts of the aircraft rotor system is generally carried out by several operators holding the pre-impregnated glass roving tape and walking back and forth around the column tooling to wind the pre-impregnated glass roving tape. This process is time-consuming and labor-intensive, and cannot control and guarantee the uniformity of tension and the winding direction during winding, which is likely to cause uneven bonding between layers, large dimensional deviation in the height direction, and poor molding quality of the final product. Contents of the invention [0003] In view of the above-mentioned situation in the prior art, the object of the present invention is to provide a winding and positio...
