DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2In an embodiment of the utility model, a lens special-shaped edge grinding wheel includes a grinding wheel body 100. The grinding wheel body 100 rotates at a high speed when in use, and can perform rough grinding, semi-fine grinding and fine grinding, as well as grooving and cutting on the outer circle, inner circle, plane and various profiles of the workpiece. A fixed seat 600 is fixed at the center of the grinding wheel body 100. The setting of the fixed seat 600 prevents the outer surface of the grinding wheel from directly contacting the main shaft and the chuck when the grinding wheel is installed and fixed. The extrusion of the chuck is likely to damage the grinding wheel. A through hole 700 is opened at the center of the fixed seat 600. The through hole 700 is set for the main shaft to insert to realize the installation of the grinding wheel body 100.

[0019] See also Figure 1-3 A flat grinding surface 200 is provided in the middle of the outer arc surface of the grinding wheel body 100. The flat grinding surface 200 serves as the main grinding part and has the grinding function of a general circular grinding wheel, and can perform preliminary rough grinding and semi-fine grinding on the lens.

[0020] See also Figure 1-3 A first convex grinding surface 300 and a second convex grinding surface 400 are respectively provided on both sides of the outer arc surface of the grinding wheel body 100. The longitudinal cross-section of the first convex grinding surface 300 is semicircular, and the outer surface of the first convex grinding surface 300 is a semicircular arc setting. The arc surface setting greatly reduces the contact area between the lens and the grinding wheel body 100, and can perform fine grinding on the lens, saving time and effort.

[0021] See also Figure 1-3 A first chamfered grinding surface 410 and a second chamfered grinding surface 420 are respectively provided on both sides of the second convex grinding surface 400. One end of the second chamfered grinding surface 420 is connected to the flat grinding surface 200. The setting of the first chamfered grinding surface 410 and the second chamfered grinding surface 420 can chamfer and grind the lens. The setting of the inclination angle makes it convenient for the staff to grind the target inclined surface of the lens, and saves time and effort.

[0022] See also Figure 1-3 A narrow flat grinding surface 430 is formed between the first chamfered grinding surface 410 and the second chamfered grinding surface 420. The narrow flat grinding surface 430 has the same grinding function as the flat grinding surface 200, and the narrow flat grinding surface 430 is convenient for fine grinding of a small area of ​​the lens, which is convenient for the staff to perform fine grinding work and saves time and effort.

[0023] See also Figure 1-3 A concave arc grinding surface 500 is connected between the first convex grinding surface 300 and the flat grinding surface 200. The setting of the concave arc grinding surface 500 can meet the requirements of arc grinding of the lens. The concave arc grinding surface 500 can connect the first convex grinding surface 300 and the flat grinding surface 200, so that the two are connected smoothly.

[0024] The working principle and use process of the utility model are as follows: when in use, the main shaft is inserted into the through hole to realize the installation of the grinding wheel body 100. The setting of the fixing seat 600 prevents the outer surface of the grinding wheel from directly contacting the main shaft and the chuck when the grinding wheel is installed and fixed. The extrusion of the chuck is easy to damage the grinding wheel. The grinding wheel body 100 rotates at high speed, and the flat grinding surface 200 is used as the main grinding part. It has the grinding function of a general circular grinding wheel and can perform preliminary rough grinding and semi-fine grinding on the lens. The outer surface of the first convex grinding surface 300 is a semicircular arc setting. The arc surface The setting greatly reduces the contact area between the lens and the grinding wheel body 100, and can perform fine grinding on the lens. The setting of the first chamfered grinding surface 410 and the second chamfered grinding surface 420 can perform chamfer grinding on the lens. The setting of the inclination angle is convenient for the staff to grind the target inclined surface on the lens. The setting of the narrow flat grinding surface 430 has the same grinding function as the flat grinding surface 200, and the narrow surface of the narrow flat grinding surface 430 is convenient for fine grinding of a small area of ​​the lens, which is convenient for the staff to perform fine grinding work and saves time and effort.
