Embodiment Construction
[0020] Describe the present invention below in conjunction with specific embodiment:
[0021] The self-adaptive winding mechanism of the composite cloth tape in this embodiment includes a hot pressing roller 8, a translation device and an angle control and measurement device.
[0022] The hot pressing roller 8 is a hollow cylindrical structure with built-in heating tubes and thermocouples. The temperature of the inner cavity of the hot pressing roller is controlled by an external industrial computer. The hot pressing roller has two functions: one is to preheat the composite material cloth tape during winding, so that The cloth tape is easier to bond together; the second is to press the mold tire tightly during the winding process, and further compact the cloth tape that has been wound on the upper mold tire. There are connecting blocks protruding from both ends of the hot pressing roller for connecting with the cylinder and the angle measuring device.
[0023] The cloth tape ...

The invention provides a tape-adaptive winding mechanism. The winding mechanism comprises a hot pressing roller, a translation device and an angle control and measure device, wherein the hot pressing roller has a hollow cylindrical structure; the translation device comprises a step motor, a screw and nut mechanism, a linear slide rail and a slide block; the angle control and measure device comprises cylinders and an angle measurer; the cylinders drive the hot pressing roller to deflect; a support plate is fixed on a fixing plate; the end portion of the support plate is provided with the angle measurer; the angle measurer comprises a potentiometer, a connection shaft and a support frame; the connection shaft connects the potentiometer with the hot pressing roller; and the hot pressing roller drives the connection shaft to rotate when the hot pressing roller deflects. The winding mechanism enables the hot pressing roller to adaptively fit to the surface of a winding part through the driving of the deflection of the hot pressing roller by the cylinders, and the compensation amount of front point positions of the hot pressing roller to be determined through measuring the deflection angle of the hot pressing roller, and controls the step motor to drive the whole body to move, so the front point positions of the hot pressing roller always maintain unchanged.
Description
technical field [0001] The invention relates to the technical field of composite material cloth tape winding, in particular to a composite material cloth tape self-adaptive winding mechanism. Background technique [0002] Composite materials, because of their advantages such as high specific strength, large specific modulus, corrosion resistance, and good shock absorption, account for an increasing proportion in the field of modern materials. Tape winding is an important method for manufacturing high-strength composite components. [0003] The CNC tape winding machine is a special equipment for winding solid rocket motor nozzle parts with carbon / phenolic, high silica / phenolic and other prepreg tapes. The machine applies constant tension to the cloth tape during winding, heats the cloth tape near the winding point, rolls the cloth tape on the molding tire with constant pressure, and solidifies the part after winding. [0004] The current winding mechanism generally fixes th...
