Problems solved by technology

[0004] The sharpening equipment currently on the market is mainly for household knives. These sharpening equipment have disadvantages such as low grinding wheel efficiency, short equipment life, low finish of the ground knives, and heavy equipment. Therefore, for large diameters (50mm-500mm range) The sharpening device for cylindrical knives has yet to be designed and created

Embodiment Construction

[0032] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] as attached figure 1 As shown, a sharpening device suitable for large-diameter corn milling cutters, the sharpening device includes: a power mechanism 1, a clamping mechanism 2, a sharpening mechanism 3, an auxiliary guiding mechanism 4, a distance adjustment mechanism 5, and a universal wheel 6 and fixed support mechanism 7. The clamping mechanism 2 includes an auxiliary ejector column 20, a three-jaw chuck and an auxiliary three-jaw chuck 24, realizing single-end clamping and double-end clamping of different types of milling cutters. In the case of one-way clamping, sometimes in order to achieve two-way fixing, the present invention designs an auxiliary plug to withstand the other side. In order to avoid scratching the milling cutter to be ground, a cylinder-head plug is used instead of a pointed thimble, that is Auxiliary ejector 20, the auxili...

Abstract

The invention provides a large-diameter corn milling cutter grinding device and belongs to the technical field of wood material cutting and processing. The device comprises a power mechanism, a clamping mechanism, a cutter grinding mechanism, an assistant guide mechanism, a distance adjusting mechanism, universal wheels and a fixed supporting mechanism. The total size of the device equals to 1600*10000*674mm, linear movement within two degrees of freedom in a plane can be implemented, the diameter Phi of adaptive cutters ranges from 50 to 500mm, and the length of the adaptive cutters ranges from 0 to 800mm. The cutter grinding device comprises two diamond coated grinding wheels, a magnetic motor is arrange in the cutter grinding device body, and the tail ends of blades are provided with hook-type collecting tanks to collect metal debris produced during cutting grinding. The device comprises three motors, one large motor is directly connected to a gearbox, and two small motors are directly connected to the grinding wheels. The assistant guide mechanism comprises a lighting device, a changeable independent drill bit and a clamping device. The fixed supporting mechanism allows the cutter grinding device body to be in movable and fixed states. The device is capable of implementing cutting grinding process of large-diameter corn milling cutters and has the advantages of wide adjustable range, low powder contamination and high efficiency.

Description

technical field [0001] The invention relates to a sharpening device, in particular to a sharpening device suitable for large-diameter corn milling cutters, and belongs to the technical field of wood cutting. Background technique [0002] As an advanced manufacturing process, high-speed cutting technology has become the mainstream development direction of material removal processing. In recent years, high-speed cutting technology has been widely used in the field of metal, plastic and stone material removal, and has begun to emerge in the field of wood processing. The corn milling cutter for wood processing has the advantages of low power consumption, low noise and no dust under high-speed cutting conditions, and can achieve the processing quality of sanding machine grinding, thereby realizing the effect of "replacing grinding by cutting". [0003] However, the blades of corn milling cutters for wood are spirally and dispersedly assembled on a cylindrical cutter body with a ...
