Automatic speed reducing device for rotating shaft

Abstract

The invention discloses an automatic speed reducing device for a rotating shaft. The device comprises a base (1), wherein the base (1) is provided with a guide sleeve (2), the guide sleeve (2) is rotationally connected with a cylinder (4) through a bearing (3), the end, facing a rotating shaft (5), of the cylinder (4) is rotationally connected to a plurality of claws (6), and the plurality of claws (6) are evenly distributed around the axis of the cylinder (4); a pull rod (7) is slidably connected to the cylinder (4), the end, close to the rotating shaft (5) , of the pull rod (7) is provided with connecting rods (8) for driving the plurality of the claws (6) to rotate synchronously, and the end, far away from the rotating shaft (5), of the pull rod (7) is provided with a first magnet (9); and the end, far away from the cylinder (4), of the guide sleeve (2) is rotationally connected to a rotating pin (24), and a second magnet (10) which is used for attracting or repelling the first magnet (9) is arranged in the rotating pin (24) in an embedded mode. According to the automatic speed reducing device for the rotating shaft, the rotating shaft can automatically stop rotating after the work is finished.

Description

Technical field [0001] The invention relates to a device for automatically decelerating a rotating shaft. Background technique [0002] In the machining process, power tools are usually used, and the power tools output rotary motion to process the workpiece. After the power tool is processed, the rotating shaft on the power tool needs to be stopped quickly to prevent the rotating shaft from continuing to drive the processing tool to rotate after the processing is completed, causing unnecessary personal and property damage, for example: cutting, milling, etc. through the rotating tool When machining is completed, the tool should be stopped as soon as possible after the processing is completed; for example, electric saws, electric screwdrivers, etc., these rotating shafts need to be stopped as soon as possible after the work is completed, but due to the lack of protection devices, it is easy to cause unnecessary personal injury. Summary of the invention [0003] The technical probl...
