Description

Technical Field

[0001] The utility model relates to a tool grinding and fixing mechanism, in particular to a tool grinding and fixing mechanism with adjustable angle, belonging to the technical field of tool grinding. Background Art

[0002] Knives are common tools. They are needed for cutting and use in daily life and mechanical manufacturing. Knives need to be ground to be sharper. After the knives are made, they all undergo a grinding process. During the grinding process, a fixing mechanism is needed to fix the knives.

[0003] The patent document with the prior art publication number CN219337374U provides a tool grinding and fixing mechanism with adjustable angle, a chassis, a supporting plate is arranged on the top of the chassis, and a supporting block is fixed on one side of the top of the supporting plate, a moving block is passed through the inside of the supporting block, and a first motor is installed on the outer wall of the moving block, a power output end of the first motor is connected to a rotating shaft, and a rotating block is fixed on the outside of the rotating shaft, and a second motor is installed on the outer wall of the rotating block. The moving block of the utility model passes through the supporting block, and the first motor is installed on the outer wall. When the first motor works, it is convenient to drive the rotating shaft to rotate, thereby driving the rotating block to rotate, so that the clamping mechanism is convenient to drive the tool to adjust the angle, and the first screw rod is driven to rotate by the second motor, thereby pushing the connecting plate to slide along the rotating block, thereby facilitating the movement of the clamping mechanism, facilitating the grinding of tools of different lengths, and adjusting the specific position at the same time, thereby improving applicability.

[0004] However, when the existing tool grinding and fixing mechanism is used, when the tool needs to be ground, the angle of the tool needs to be adjusted. However, due to the poor flexibility of the tool grinding and fixing mechanism, although a certain angle adjustment can be performed, during the adjustment process, although the fixing mechanism drives the tool to adjust the angle, the position of the tool will change to a certain extent. Since the fixing mechanism cannot adjust the position and angle at the same time, the tool grinding adjustment accuracy is low, thereby affecting the grinding effect. For this reason, we propose a tool grinding and fixing mechanism with adjustable angle. Utility Model Content
