The invention relates to a woodwork knife grinder and belongs to the technical field of woodwork knife grinder structures. The woodwork knife grinder comprises a base and a base cover, wherein a starting button is arranged on the base cover, long strips are arranged on two sides of the base horizontally, and polished shafts are arranged on the top portions of the long strips and fixedly connected with a cover plate through bearings. A bearing block is arranged on the cover plate, a horizontal shaft is arranged in the inner hole of the bearing seat, the horizontal shaft is axially provided with a small slide carriage, a large slide carriage and a motor in sequence, a hand wheel is fixedly connected to the small slide carriage and the large slide carriage through screw rods, a grinding wheel is axially arranged at the bottom of the motor, the cover plate is provided with a hand rod connected with the bearings, and a pressing plate for pressing blades is arranged on one transverse side of the top of the base. The woodwork knife grinder is provided with the polished shafts with large hardness, in the knife grinding process, the motor drives the grinding wheel to rotate, the hand rod drives the bearings to slide on the optical shafts, the optical shafts are abrasion-resistant and long in service life, high-accuracy knife grinding can be achieved, and constant accuracy of the blades are guaranteed.
Description
[0001] technical field [0002] The invention relates to a woodworking knife sharpener, which belongs to the technical field of woodworking knife sharpener structures. Background technique [0003] Existing knife grinder is to slide on guide rail by four bearings, and realizes grinding through the rotation of emery wheel and manual back and forth dragging. But there are defects in this structure, because the bearing often slides on the cast iron, which causes the guide rail to sag, and directly affects the sharpening accuracy. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings of the above-mentioned prior art, and to provide a woodworking knife sharpening machine which is durable and has high knife sharpening precision. [0005] A woodworking knife sharpener of the present invention comprises a base 1 and a base cover 2, the base cover 2 is provided with a start button 3, and the special feature is that a strip 4 is inst...
