[0014] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0015] Example 1

[0016] See Figure 1 and Figure 2 As shown, the crankcase cover deburring device involved in this embodiment includes a chassis 1, an outer cylinder 2 at the center of the chassis 1, a core column 3 rotatably connected inside the outer cylinder 2, a stud part 4 coaxially provided on the top of the core column 3, the diameter of the stud part 4 being smaller than the diameter of the core column 3, a round nut 5 threadedly connected to the stud part 4, a non-rotating cylindrical turning groove 6 opened on the top of the stud part 4, a tool holder 7 slidably connected to the chassis 1 and moving radially along the outer cylinder, a tool hole 8 opened on the tool holder 7, a turning tool 9 with the cutting edge facing upward inserted into the tool hole 8, a mounting plate 10 fixed on the chassis at the end of the tool holder 7 facing away from the outer cylinder, an adjusting screw 11 with its end abutting against the tool holder 11 threadedly connected to the mounting plate 10, an elastic element 12 with one end abutting against the tool holder 7 and the other end abutting against the outer cylinder 2, the elastic element 12 being a compression spring.
