A dental bur safety grinder with variable speed

Abstract

The invention belongs to the technical field of grinding machines, and in particular relates to a variable speed type dental machine needle safety grinding machine. The variable speed type dental machine needle safety grinding machine comprises a shell, a power unit, an arc-shaped swing plate, a reset plate spring, a chuck, a variable speed cone and the like. Kinetic energy of the power unit is transferred to a power gear through a power rotary shaft, an electromagnetic switch and a power gear rotary shaft. Kinetic energy of the power gear is transferred to a gear ring of the chuck through thedriving gear, so that the chuck rotates around the axis of the gearing ring of the chuck. A first mill knife mechanism, a second mill knife mechanism, a third mill knife mechanism and the chuck are matched with each other to machine a workpiece in multi-degree of freedom. The variable speed type dental machine needle safety grinding machine solves a phenomenon that the grinding machine works unsmoothly or is blocked as the position of the workpiece is unreasonable, and achieves purposes of buffering the chuck, reducing mechanical damage to the grinding machine and protecting the workpiece. Meanwhile, three protecting paths are designed to protect the personal safety of an operator, so that the using safety of the grinding machine is improved. The variable speed type dental machine needlesafety grinding machine is simple and compact in structure and high in safety and has a relatively good actual application effect.

Description

[0001] Technical field [0002] The invention belongs to the technical field of grinding machines, in particular to a dental bur safety grinding machine with variable speed. Background technique [0003] At present, the traditional dental bur grinding machine can only process the workpiece. During the long-term processing of the workpiece, the workpiece is often placed in an unreasonable position and the grinding machine is not working smoothly or stuck, which increases the need for grinding machines and workpieces. mechanical damage, reducing the service life of the grinder. In addition, it is inevitable that the operator's fingers will be squeezed by the sharpening mechanism of the workpiece during the long-term processing work, and even in serious cases, the operator's hand will be seriously injured. [0004] The present invention designs a dental bur safety grinding machine with variable speed to solve the above problems. Contents of the invention [0005] In order to ...
