Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tool grinding and clamping, in particular to a numerical control blade grinding and clamping structure. Background Art
[0002] The clamping mechanism ensures that the blade is stably and precisely fixed during the sharpening process. This clamping mechanism includes a fixture, a support plate, and an adjustment mechanism. It provides precise positioning of the blade, preventing vibration or deviation during sharpening, thereby improving sharpening quality and blade life.
[0003] For example, a blade grinding clamp with application number CN218696707U includes two tool clamps, an adjustment bolt, a fixed seat, and a booster wheel. The top surface of the fixed seat is connected to the tool clamp, and the bottom surface is connected to the booster wheel. The tool clamp is connected by the adjustment bolt and then slides toward the fixed seat. The utility model has a novel structure. By providing a fixed seat, the tool clamp and the fixed seat are connected by a threaded engagement, which greatly improves the firmness of the blade clamping. In addition, the booster wheel is connected separately from the tool clamp. On the one hand, the clamping range is minimized, enabling the grinding of small-sized blades. On the other hand, the booster wheel is not limited by space and its width can be maximized, thereby increasing the contact area with the grinding device and improving stability. The utility model has a simple structure, low cost, long service life, and can be used for grinding various types of blades.
[0004] The above patent proposes to use two tool clamps to move toward each other simultaneously to clamp the blade. However, in actual use, the left and right sides of the blade are clamped. When sharpening the blade, the front and back sides of the blade are not clamped, which affects the stability of the blade and makes it inconvenient to use.
[0005] Therefore, we propose a CNC blade grinding and clamping structure to solve the above problems. Utility Model Content
