Detailed Description

For further explanation of the various embodiments, the drawings which form a part of the disclosure and which are incorporated in and constitute a part of this specification, illustrate embodiments and, together with the description, serve to explain the principles of operation of the embodiments, and to enable one skilled in the art to understand the embodiments and advantages of the disclosure for reference and without scale, wherein elements are not shown in the drawings and like reference numerals are used to refer to like elements generally.

According to the embodiment of the utility model, a novel cylindrical grinding tool is provided.

The utility model is further explained by referring to the accompanying drawings and the specific embodiments, as shown in fig. 1-6, the novel cylindrical grinding tool according to the embodiment of the utility model comprises a concentric shaft 1, wherein a limiting block 2, a movable baffle 3, a gasket 4, a locking ring 5 and a workpiece fixing block 6 are arranged on the concentric shaft 1, the workpiece fixing block 6 is located between the limiting block 2 and the movable baffle 3, the locking ring 5 is located on the outer side of the movable baffle 3, and the gasket 4 is located at the close contact position of the locking ring 5 and the movable baffle 3.

In one embodiment, the concentric shaft 1 is further provided with thimble holes 11, screws 12 and fastening threads 13, two groups of thimble holes 11 are oppositely arranged at the center positions of two sides of the concentric shaft 1, the screws 12 are movably connected to the upper ends of one group of thimble holes 11 through threads, and the fastening threads 13 are far away from the screws 12 and are located at the other end of the concentric shaft 1.
