Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] The motor 14 of the present invention has two ends of shaft extensions, one end drives the common 7-inch emery wheel to run for coarse grinding of cutters, and the other end drives the cup-shaped emery wheel 12 to rotate, and combines the pendulum sharpening mechanism to sharpen the blade. When the grinding wheel on the left side is rough grinding, hold the tool with your hand, and use the bracket to grind the tool. When the right side is finely grinding, use the pressure knife plate 9 and the handle 10 to clamp and fix the knife together, and manually swing the knife sharpening attachment to swing back and forth. The working process moves back and forth like a pendulum, so it is called a pendulum knife sharpener.

[0014] When the tool is clamped, the knife pressing plate 9 is pressed against the tool, and the handle 10 at the rear of the knife pressi...

Abstract

The invention relates to the field of machines, in particular to a pendulum tool grinding machine used for narrow and long tools such as the kind of woodworking chisels. The pendulum tool grinding machine is composed of a motor and a tool grinding cup type grinding wheel and is characterized in that the tool grinding cup type grinding wheel is installed on a main shaft on the right side of the motor; a lifting shaft, an adjusting seat, an adjusting nut and a swing seat are installed on the upper face of the right side; a tool pressing plate and a tool clamping handle are installed on the lower face of the swing seat; and a bracket and a left protection lens are installed on the left side of the motor. The pendulum tool grinding machine has the beneficial effects that the novel tool grinding machine is provided, rough grinding of a common grinding wheel machine and finish grinding of a pendulum mechanism are integrated, the motor is arranged in the middle and is used for driving a grinding wheel piece and the cup type grinding wheel to rotate at the two ends; and a transmission mechanism is relatively simple, transmission fault sources are reduced, and products are attractive in appearance, compact and stable.

Description

technical field [0001] The invention relates to the field of knife sharpeners, in particular to a pendulum knife sharpener used for long and narrow woodworking chisel knives. Background technique [0002] The traditional desktop knife grinder seen in the current market is installed on the base by an independent motor as a power source, and one end of the motor shaft extension directly drives the belt pulley or friction wheel or worm gear to run. The belt drive is to reduce the transmission to the main shaft through the belt pulley. The friction wheel mode is that the motor shaft directly drives the friction wheel to reduce the transmission to the main shaft. One of the two ends of the main shaft is a grinding wheel, and the other side is a cowhide wheel for polishing the blade. The knife sharpeners with the above transmissions are all speed reduction transmissions with low speed, and the grinding wheels for knife sharpening generally rotate at about 100 rpm. [0003] We ha...
