A screw rotating device for automatic tooth removal

Abstract

The invention provides a screw rotating device for automatic tooth removal, which belongs to the technical field of manufacturing equipment. It includes a motor, a transmission shaft and a screw, and the transmission shaft and the screw are connected by an automatic tooth removal component, wherein the automatic tooth removal component includes an outer sleeve and an inner sleeve, the outer sleeve is fixedly connected to the transmission shaft, and the screw is fixedly connected to the inner cylinder. The outer sleeve is set outside the inner cylinder and is relatively fixedly connected to the inner cylinder through elastic parts; in normal state, the motor drives the transmission shaft to rotate, which in turn drives the outer sleeve, inner cylinder and screw to rotate synchronously. When the screw rotation is limited, the inner The sleeve and the outer sleeve are separated from the fixed connection state, and the outer sleeve can slide and rotate outside the inner sleeve to realize the automatic tooth removal of the screw. In the present invention, the screw and the transmission shaft are not fixedly connected, but relatively fixedly connected through the automatic detooth assembly. Normally, the screw and the transmission shaft rotate synchronously. When the rotation of the screw is limited, the screw and the transmission shaft are disconnected, and the screw will not Over-rotate with the drive shaft to protect the screw.

Description

technical field [0001] The invention belongs to the technical field of manufacturing equipment, relates to a displacement transmission structure, and in particular relates to a screw rotating device for automatic tooth removal. Background technique [0002] In modern automated machinery and equipment, the movement of objects is often involved, and the displacement is usually driven by driving parts such as motors and cylinders. For example, a screw motor is a type of motor that converts the rotary motion of the motor into linear motion. It includes a motor body and a screw assembly. The screw assembly includes a screw and a slider. The rotating shaft of the motor body is connected to the screw through a coupling, thereby driving the screw to rotate. sports. In the existing screw motor, the shaft and the screw are connected by a coupling, and the shaft and the screw rotate synchronously. [0003] However, when the screw motor is actually used, the rotation of the motor shaf...

Problems solved by technology

[0003] However, when the screw motor is actually used, the rotation of the motor shaft has a certain inertia, and the screw tends to over-rotate. If the slider on the screw is stuck by the limit, the over-rotation of the screw will affect the screw opening of the screw and the slider. Cause damage, long-term wear will reduce the accuracy of slider movement, which is very unfavorable to assembly

Especially for large-scale equipment, it needs to be equipped with a motor with greater power as the driving part. Its torque is greater, and the inertia driven by it during rotation is also stronger. The more difficult it is to control the rotation accuracy of the screw, the screw and slider are often easily damaged. Its service life has virtually increased production costs and labor intensity, and this phenomenon needs to be resolved
