Grinding wheel lifting device in scissors grinding machine

Abstract

The invention discloses a grinding wheel lifting device in a scissors grinding machine. The grinding wheel lifting device comprises a main machine frame and a mounting frame, wherein the main machine frame is provided with a base; the base is provided with an air cylinder; the piston rod of the air cylinder is fixed with one end of a sliding block; the sliding block slides on the base under the driving of the air cylinder; the other end of the sliding block is connected with a connecting frame; the connecting frame is articulated with the mounting frame through a connecting shaft; the grinding wheel and a drive motor on the mounting frame are located on two sides of the connecting shaft, respectively; the mounting frame is provided with a guide wheel bracket; a guide wheel is mounted on the guide wheel bracket; one side of the main machine frame close to the drive motor is provided with a guide rail; the outer end of the guide rail is provided with an inclined plane which is downwardly inclined from the top surface of the guide rail; and the guide wheel moves on the guide rail. According to the invention, the grinding wheel lifting device increases the working efficiency and can enable the grinding wheel to leave the surfaces of shear blades automatically after the processing the surfaces of the shear blades is completed.

Description

technical field [0001] The invention relates to the field of scissors processing, in particular to a grinding wheel lifting device in a scissors grinding machine. Background technique [0002] Scissors are made of two scissor blades hinged to each other. In the process of scissors processing, in order to make the scissors more labor-saving in use, the inner surfaces of the two scissor blades that are in contact with each other are generally ground separately so that they are in contact with each other. The middle part of the inner surface of the inner surface is a concave concave surface to reduce the mutual contact area of ​​the two scissor blades; the concave concave surface that needs to be ground on the scissor blade is very close to the scissor blade to make the two scissor blades mutually The hinged hinge hole, on the one hand, in order to ensure the grinding quality of the concave surface of the scissor blade, on the other hand, in order not to damage the hinge ho...

[0002] Scissors are made of two scissor blades hinged to each other. In the process of scissors processing, in order to make the scissors more labor-saving in use, the inner surfaces of the two scissor blades that are in contact with each other are generally ground separately so that they are in contact with each other. The middle part of the inner surface of the inner surface is a concave concave surface to reduce the mutual contact area of ​​the two scissor blades; the concave concave surface that needs to be ground on the scissor blade is very close to the scissor blade to make the two scissor blades mutually The hinged hinge hole, on the one hand, in order to ensure the grinding quality of the concave surface of the scissor blade, on the other hand, in order not to damage the hinge hole and affect the installation and use of the scissors, so when the concave surface of the scissor blade surface is processed, it must be Make the surface of the scissors away from the grinding wheel; the traditional method of making the surface of the scissors away from the grinding wheel is: first, the worker judges whether the concave surface of the scissors has been processed, and when the worker judges that the concave surface of the scissors has been processed, the worker quickly holds the scissors The scissors leave the grinding wheel, but due to the limitation of the physical strength of the workers, on the one hand, the workers cannot timely and accurately judge that the concave surface of the scissors has been processed every time; Vibration is generated, which not only makes it difficult to ensure the grinding quality, but also greatly reduces the work efficiency
