Description

Technical Field

[0001] The utility model relates to the field of tool sharpening, in particular to a tool sharpening mechanism. Background Art

[0002] When the knife is calcined, the iron or steel on the surface will oxidize or have a high carbon content and become brittle. Sharpening can be divided into concave grinding, chisel blade grinding, surface grinding, cavalry grinding, arc grinding and heavy sharpening. Tools sharpened in different ways have different properties and different uses. At present, when operators sharpen tools, they generally use grindstones or polishing discs to grind and sharpen the tools to make the blades sharper. With this grinding method, if the inclination of the tool being sharpened is different, the edge of the blade will be uneven, and the operator needs to sharpen the two blade surfaces of the tool the same number of times, which places high demands on the operator and has low work efficiency. For this reason, the present application designs a tool sharpening mechanism to solve the above problems. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Example: See Figure 1-5A tool sharpening mechanism in the utility model comprises a base plate 2, four supporting feet 1 are symmetrically and equidistantly arranged at the bottom end of the base plate 2, a motor box 3 is arranged on the top of the base plate 2, baffles 5 are symmetrically arranged on both sides of the base plate 2, a clamping device 4 is arranged above the base plate 2, and two supporting seats 6 are arranged on the top of the base plate 2; a motor is installed inside the motor box 3, a screw rod 7 is arranged on the supporting seat 6, the screw rod 7 is connected to the motor shaft, a threaded sleeve is arranged below the clamping device 4, and the screw rod 7 is threadedly connected to the threaded sleeve. Through the design of the motor box 3, the motor and the wires connected to the motor can be better protected; through the design of the threaded sleeve and the screw rod 7 below the clamping device 4, the clamping device 4 can be better moved, so that the clamped tool can be sharpened back and forth.

[0019] In the utility model, the clamping device 4 includes a threaded rod 11 and a clamping plate 12. The threaded rod 11 is located in a slot above the clamping device 4, and the connecting end of the clamping plate 12 is slidably located in the slot. Through the design of the threaded rod 11 and the clamping plate 12, the tool can be better clamped; a slot is opened on the baffle 5, and a rectangular support rod 9 is connected to the slot. A grinding wheel 8 is fixedly connected to the middle part of the support rod 9, and a V-shaped circular groove is opened in the middle part of the grinding wheel 8. By opening a slot on the baffle 5, the distance between the tool and the grinding wheel 8 can be better adjusted.
