[0025] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0026] In the present utility model, unless otherwise stated, directional words such as "upper, lower, center, top, bottom" contained in the terms merely represent the orientation of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0027] See also Figures 1 to 3 The utility model provides a deburring tool, which includes a tool body 1. The tool body 1 is disc-shaped and the middle part of the top surface is inwardly recessed to form a positioning recess 2 for positioning. A through hole 3 is opened in the center of the positioning recess 2. A plurality of cutting columns 4 for removing burrs of waist-shaped holes on the casting to be deburred are arranged along the circumference of the through hole 3; one or more cutting protrusions 5 for removing burrs on the outer circle of the casting and one or more positioning grooves 6 for positioning the casting are arranged on the edge of the top surface of the tool body 1 along the circumference of the positioning recess 2, and a plurality of cutting columns 4 are also arranged between the cutting protrusions 5 and the positioning grooves 6; wherein,

[0028] Spaces for accommodating the casting to be deburred are formed in the positioning recess 2, between adjacent cutting protrusions 5 and in the positioning groove 6. The cutting column 4 matches the size and shape of the through hole on the casting.

[0029] According to the above technical solution, when in use, the casting to be deburred is placed into the tooling from top to bottom and the burrs can be removed by squeezing it hard, thereby achieving rapid burr removal, eliminating the grinding process, and preventing the problem of missing burrs, thereby improving the parts processing efficiency and saving processing costs.
