3D printer consumable item conveying clamping device based on magneto-rheological effect

Abstract

The invention provides a 3D printer consumable item conveying clamping device based on the magneto-rheological effect. The device is composed of a clamping device and a transmitting device, and the core part, namely the clamping device is composed of a rotating cylinder, an end cover, a screw, a sealing shaft sleeve, a bearing, a fixing shaft, a sensing coil, magnetorheological fluid, a fixed endbase, a handle and a button. The rotating cylinder is in an involute shape with the radius increased continuously, and the bearings at the two ends can rotate around the fixed shaft. The end cover isfixed to the rotating cylinder through the screw, a groove is formed in the inner side, the bearings are embedded into the grooves, and isolation from the magnetorheological fluid is achieved throughthe sealing shaft sleeve. One end of the fixed shaft extends outwards to be connected with the fixed end base, a groove is formed in the middle part, and the sensing coil is wound in the groove. A movable sealed cavity is formed by the inner wall of the rotating cylinder, the outer wall of the fixed shaft and the sealing shatf sleeve, and the magnetorheological fluid is sealed in the cavity. The 3D printer consumable item conveying clamping device has the beneficial effects of being compact in structure, good in controllability, quick in reaction and the like.

Description

technical field [0001] The invention relates to a 3D printer consumable transmission and clamping device, in particular to a 3D printer consumable transmission and clamping device based on the magneto-rheological effect. Background technique [0002] With the rapid development of science and technology, 3D printing technology continues to mature. Various universities and scientific research institutions have introduced 3D printers to print auxiliary parts, which has brought great convenience to our researchers, teachers and students. At the same time, 3D printers Various unreliable factors appear in the process of use. Among them, the material conveying device placed on the back of the 3D printer may slip or get stuck during use. This is caused by improper clamping force: excessive clamping force will cause the consumables to be stuck, and too small clamping force will cause the consumables to slip, which will cause the consumables to not be transported normally. In view o...
