Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1:
as shown in fig. 1-3, a bearing outer ring inner groove grinding wheel connecting rod comprises a rod body 1, a groove 2 is arranged at the front end of the left side of the rod body 1, an internal thread is arranged in the groove 2, a grinding wheel component 3 is screwed on the left side of the rod body 1 through the internal thread, a hexagonal hole is arranged in the middle of the left end of the grinding wheel component 3, the grinding wheel component 3 comprises a grinding wheel 31 and a grinding wheel rod 32 fixedly installed at the center of the right side of the grinding wheel, an external thread matched with the internal thread in the groove 2 is arranged on the grinding wheel rod 32, and the rear end of the right side of the rod body 1 is connected in the internal thread of a machine spindle through the external thread.
The internal thread in the groove 2 is used for screwing and fixing the grinding wheel component 3, the external thread at the rear end of the right side of the rod body 1 is used for being connected in the internal thread of the machine spindle, the right side of the rod body 1 is screwed into the internal thread of the machine spindle, the rod body 1 is screwed through a movable wrench or an open wrench, then the grinding wheel component 3 is screwed into the internal thread of the rod body 1, and then the grinding wheel component 3 is screwed through a hexagonal hole in the middle of the front end of the grinding wheel component 3 by using a hexagonal wrench, because the traditional grinding wheel is axially compressed through a gasket and adopts a structure that a nut is adopted to splice the rod body (see figure 4), the axial thickness of the gasket cannot be kept consistent, the verticality difference between the grinding wheel component 3 and the spindle is caused, and the problem of jumping exists during processing, in the embodiment, the verticality of the matching part between the grinding wheel 31 and the groove 2 is ensured through the structure of the grinding wheel component 3, and then the external thread on the grinding wheel rod 32 which is coaxial with the groove 2 is connected and installed, the verticality of the grinding wheel component 3 and the rod body 1 is guaranteed, and the product processing quality is improved while the phenomenon that the grinding wheel component 3 jumps is avoided.
