Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and in particular to a safety-type heavy-duty grinding wheel. Background Technology

[0002] Heavy-duty grinding wheels are a crucial product among grinding wheel products. They bear a large load during use, but the high heat generated during operation can affect the safety of continuous use of the grinding wheel body. Their overall heat resistance is relatively poor. Furthermore, the installation position typically uses a center hole located at the center of the grinding wheel for mounting. When directly fastened with bolts, the stability of the fit is relatively poor, and the anti-loosening safety and load-bearing capacity of the mating position are also relatively weak. Utility Model Content

[0003] The purpose of this invention is to provide a safe heavy-duty grinding wheel. Its outer side features a heat-resistant safety groove, ensuring better heat resistance during use and allowing for better removal of grinding debris. The central mounting position features an inward-curving, stable safety groove, which, when used with reinforcing mounting accessories, allows for an embedded, secure fit. After tightening, the mating area deforms outward, creating a reliable anti-loosening effect. This ensures the grinding wheel has stronger overall load-bearing capacity, better shock resistance, and more reliable stability, effectively improving safety during use.

[0004] The technical solution of this utility model is as follows:

[0005] A safety-type heavy-duty grinding wheel is characterized by: a cylindrical grinding wheel body structure with a central axis pointing left and right; uniformly distributed heat-resistant safety grooves on the outer cylindrical surface of the grinding wheel body structure; symmetrical conical center-fitting safety grooves on the left and right end faces of the grinding wheel body structure; a conical stable combination safety groove on the inner side of the center-fitting safety groove; the dimension of the inner side of the stable combination safety groove being larger than the dimension of the connection position with the center-fitting safety groove; an integrally formed reinforced center-fitting column at the center of the stable combination safety groove; and a fully through cylindrical center mounting combination hole at the central axis of the reinforced center-fitting column.

[0006] Furthermore, the depth of the central fitting safety groove is less than one-third of the total thickness of the grinding wheel body structure.

[0007] Furthermore, the taper of the stable combined safety groove is 5 degrees.

[0008] Furthermore, the height of the reinforced central mating column is less than the depth of the stable combined safety groove.

[0009] Furthermore, the outer edge of the central mounting hole is provided with a chamfered structure for easy mounting.

[0010] The beneficial effects of this utility model are:

[0011] The outer side of this utility model is equipped with a heat-resistant safety groove, which ensures better heat resistance during use and allows for better discharge of grinding debris. The central mounting position is equipped with an inwardly recessed, stable combined safety groove, which can be used with reinforced mounting accessories for embedded fastening. After fastening, the mating position deforms outward, forming a reliable anti-loosening effect, ensuring that the grinding wheel has a stronger overall load-bearing capacity, better shock resistance, and more reliable stability during use, and effectively improving safety during use.

[0019] like Figures 1 to 6As shown, a safety-type heavy-duty grinding wheel includes a cylindrical grinding wheel body structure 1 with its central axis pointing left and right. The outer cylindrical surface of the grinding wheel body structure 1 has evenly distributed heat-resistant safety grooves 2, ensuring safer heat dissipation for the main body structure during use. This does not affect side grinding operations. The overall structural strength is guaranteed. Symmetrical conical center-fitting safety grooves 3 are provided on the left and right end faces of the grinding wheel body structure 1, ensuring greater space at the center position for installation and fitting with reinforcement accessories. A conical stabilizing combination safety groove 4 is provided on the inner side of the center-fitting safety groove 3, allowing for fastening with reinforcement accessories during installation, ensuring higher load-bearing strength and providing protection for the grinding wheel body during installation. The inner dimension of the stabilizing combination safety groove 4 is larger than the dimension of the connection point with the center-fitting safety groove 3, resulting in more internal space. After fastening, the fitting position provides reliable anti-loosening under the tightening force, making the grinding wheel more load-bearing during use. The central position of the stable combined safety groove 4 is provided with an integrally formed reinforced central mating column, which increases the strength of the central position. The central axis of the reinforced central mating column is provided with a full-through cylindrical central mounting combination hole 5, which can be used with fastening bolts and other accessories for central tightening. It adopts a brand-new structural design. The outer side is provided with a heat-resistant safety groove, which can ensure better heat resistance during use and allow better discharge of grinding debris. The central mounting position is provided with an inward-curving stable combined safety groove, which can be used with reinforced mounting accessories for embedded fastening. After tightening, the mating position deforms outward, which can form a reliable anti-loosening effect, ensuring that the grinding wheel has a stronger overall load-bearing capacity, better shock resistance, more reliable stability, and effectively improves safety during use.

[0020] Preferably, the depth of the center fitting safety groove 3 is less than one-third of the total thickness of the grinding wheel body structure 1, which can ensure better strength of the grinding wheel body and a larger space for use when the grinding wheel body is in use.

[0021] Preferably, the taper of the stable combination safety groove 4 is 5 degrees, which facilitates installation and mating. If the angle is too large, it will affect the smoothness of installation, and if the angle is too small, the anti-loosening fit safety after tightening will be relatively poor.

[0022] Preferably, the height of the reinforced central mating column is less than the depth of the stable combination safety groove 4, so that the space occupied by the central position structure is relatively small, which makes it easier to produce.

[0023] Preferably, the outer edge of the central mounting hole 5 is provided with a chamfered structure for easy installation and assembly, which makes assembly and assembly more convenient, has a guiding function, and can improve the efficiency of assembly.

[0024] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
