Saw blade grinding machine

Abstract

The invention discloses a saw blade grinding machine which comprises a base, a saw blade positioning device, a grinding wheel feeding device, a grinding wheel device, a saw blade feeding device, a saw blade shifter and a power device, wherein the base is vertical, a plurality of through holes is arranged on the periphery of the bottom of the base, and the base can be fixed on the ground through a fixing device; the saw blade positioning device is fixed on a vertical wall plate of the base, and can be used for positioning a saw blade and regulating the center of a circle of the saw blade; the grinding wheel feeding device is arranged on a chassis at the top end of the base; the grinding wheel device is controlled by the grinding wheel feeding device to move up and down in a reciprocating manner so as to utilize a grinding wheel to grind saw teeth of the saw blade; the saw blade feeding device is arranged on the chassis at the top end of the base; the saw blade shifter is controlled by the saw blade feeding device to act on the saw teeth of the saw blade, so that the saw blade rotates and the saw teeth are fed to a grinding position one by one for being conductive to grinding; and the power device drives the grinding wheel feeding device and the saw blade feeding device.

Description

technical field [0001] The invention relates to the field of saw blade grinders, in particular to a saw blade grinder for vertically positioning and processing saw blades. Background technique [0002] In the prior art, large-scale saw blades are widely used, especially in fields such as wood processing. As a common cutting tool, saw blades need to maintain a sharp cutting edge. After a period of use, the cutting edge is worn and will affect its performance. cutting speed and cutting efficiency. [0003] In order to avoid replacement, we can regrind the cutting edge to keep the saw blade in good cutting. The commonly used saw blade grinder is set horizontally, which fixes the saw blade horizontally on the positioning shaft, and uses a saw tooth The reciprocating linear displacement grinding wheel is used for grinding. When grinding the cutting edge, the saw blade needs to rotate at a constant speed relative to the grinding wheel. However, this kind of horizontal grinding sa...

[0002] In the prior art, large-scale saw blades are widely used, especially in fields such as wood processing. As a common cutting tool, saw blades need to maintain a sharp cutting edge. After a period of use, the cutting edge is worn and will affect its performance. Cutting speed and cutting efficiency

[0003] In order to avoid replacement, we can regrind the cutting edge to keep the saw blade in good cutting. The commonly used saw blade grinder is set horizontally, which fixes the saw blade horizontally on the positioning shaft, and uses a saw tooth The reciprocating linear displacement grinding wheel is used for grinding. When grinding the cutting edge, the saw blade needs to rotate at a constant speed relative to the grinding wheel. However, this kind of horizontal grinding saw blade grinder takes up a lot of space, and due to the influence of gravity, The circumference of the saw blade is not easy to keep level, and the position of the grinding origin is difficult to control, resulting in inaccurate grinding when grinding the cutting edge of the saw blade, resulting in grinding failure
