Hinge and cutting and grinding device for machining hinge

Abstract

The invention discloses a hinge and a cutting and grinding device for machining the hinge. The hinge comprises an upper hinge piece, a lower hinge piece and a hinge shaft. The upper hinge piece and the lower hinge piece are hinged through the hinge shaft. Installing grooves are formed in the front face of the upper hinge piece. Auxiliary hinges are installed in the installing grooves. The two opposite sides of each installing groove are each of a step shape. A screw hole is formed in each auxiliary hinge. The two opposite sides of each auxiliary hinge are each of a step shape. The step faces on the two sides of each installing groove and the step faces on the two sides of the corresponding auxiliary hinge are each provided with a tooth row for meshing. The auxiliary hinges and the upper hinge piece are used in cooperation, the sliding problem and assembling misplug problem can be solved effectively through the tooth rows, a seam between two parts of an object is reduced, and attractiveness is increased. The cutting and grinding device comprises a machine case. A die, a cutting device, a turning device, a grinding device, a hinge sending device and a feeding device are arranged on the top of the machine case. The cutting and grinding device has the positioning, cutting, grinding and conveying integrated automatic machining effect, work efficiency is improved, and labor cost is reduced.

Description

technical field [0001] The present invention relates to a hardware processing equipment, more specifically, it relates to a hinge and cutting and grinding equipment for the hinge. Background technique [0002] Hinges, also known as hinges, often form a two-fold type, which is a part that connects two parts of an object and enables them to move. It is mainly used for cabinet doors, windows, doors, etc. [0003] The Chinese utility model patent with application number 2018211456581 discloses a hinge, which includes a connecting shaft, a first connecting part, a second connecting part, a first fan blade, a second fan blade, a first locking part and Second locking member. The first connecting portion and the second connecting portion are respectively rotatably connected to the connecting shaft. The first fan blade is arranged on one side of the connecting shaft and is slidably connected to the first connecting portion. The sliding direction is perpendicular to the axial directi...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a hinge and cutting and grinding equipment for processing the hinge, which solves the problem of sliding of the blade due to excessive force and vibration between the connecting part and the fan blade
