[0034] In combination with the above structure, the graphite electrode is located in the box body 1. When grinding the graphite electrode, the transparent box door 2 is closed to prevent the dust generated by grinding from entering the external environment, thereby preventing pollution of the working environment and ensuring the health of the staff; the powder generated when the graphite electrode is ground is collected by the collection box 11 for easy disposal.

[0035] Combined with Figure 3 The clamping assembly 4 includes a connecting plate 12 installed at the output end of the motor 3, a slide groove 1201 is provided on one side of the connecting plate 12, a threaded rod 13 is connected to the bearing between the two side walls of the slide groove 1201, a pair of sliders 14 threadedly connected to the threaded rod 13 are symmetrically slidably connected in the slide groove 1201, and the threads on the pair of sliders 14 are in opposite directions. A clamping plate 1401 is provided at the end of the slider 14, and an arc-shaped rubber pad 15 is fixed to the inner side of the clamping plate 1401.

[0036] In combination with the above structure, when the graphite electrode is placed, one end of it is inserted between a pair of clamping plates 1401, and the threaded rod 13 is rotated so that a pair of sliders 14 slide relatively in the slide groove 1201, so that the pair of clamping plates 1401 clamp one end of the graphite electrode, and the arc-shaped rubber pad 15 acts on the graphite electrode to increase the stability of the graphite electrode clamping; and the other end of the graphite electrode is limitedly supported by the positioning component 7 and the auxiliary component 8.

[0037] Combined with Figure 4 The knocking assembly 6 includes a sleeve 16 that passes through the horizontal support plate 5 longitudinally, and a roller knocking head 17 is adjustably installed on the upper end of the sleeve 16.

[0048] In combination with the above structure, when the moving component 9 is in use, the motor three 38 drives the threaded rod five 37 to rotate, so that the slider two 39 slides on the top wall inside the box body 1, thereby driving the hydraulic cylinder 40 and the grinding component 10 to move horizontally. The hydraulic cylinder 40 drives the grinding component 10 to rise and fall, so that the grinding component 10 contacts the upper end of the graphite electrode curved surface and moves horizontally, which is convenient for grinding the graphite electrode.
