Problems solved by technology

[0004] 1. The traditional equipment of manual operation and manual measurement is still used. It is inconvenient to adjust the distance between the grinding discs according to the length of the graphite electrode. Due to interference from human factors, there are problems of large operating errors and low measurement accuracy;
[0005] 2. When the graphite electrode has a flat head, place it on the trolley. First, it needs to be centered manually, that is, check whether it is in the middle of the grinding discs at both ends by manual means. It usually takes two or three times to achieve the centering, and then the trolley passes through the steel wire rope below. Traction movement for grinding, long time will also cause the wire rope to change in tension, or even break, affecting normal work

[0042] Both sides of the top surface of the bottom plate 1 are provided with a pair of symmetrically fixed L-shaped plates 11, and the outer sides of the top surface of each L-shaped plate 11 are provided with vertically fixed side plates 12, and ...

Embodiment 2

[0051] Embodiment 2: In Embodiment 1, there is also the problem that the graphite electrode is not firmly fixed during processing. Therefore, on the basis of Embodiment 1, this embodiment also includes:

[0052] In the present invention, a movable hinged semicircle cover plate 46 is provided on the rear side of the top surface of the semicircle clamp 4, and a semicircle rubber pad 47 is provided on the inner wall of the semicircle cover plate 46 and the semicircle clamp 4, and two semicircle rubber pads are provided. The pads 47 are pressed against the upper and lower sides of the graphite electrode 41 respectively, and the front side of the semicircle cover plate 46 is evenly provided with some fastening bolts 48 that penetrate through the spiral. Side screw locking; center the graphite electrode 41 that needs to be polished flat on the semicircle clamping plate 4, cover the semicircle cover plate 46, and screw the fastening bolts 48 respectively, the inner ends of each fasten...

Embodiment 3

[0053] Embodiment three: see Image 6 , in the present embodiment, the present invention also proposes a method for using a graphite electrode flat head device, comprising the following steps:

[0054] Step 1, drive motor 2, sliding motor 33, linear motor 50, and hydraulic cylinder 42 are electrically connected to external power supply respectively through power line, according to the length of graphite electrode 41, adjust the distance between two flat-head grinding discs 14, through the rotating tool The word shaft 18 drives the screw rod 19 to cooperate with the threaded cylinder 110 to spirally rotate, and then drives the square rod 16 to slide outward or inward along the square groove 15, thereby changing the distance between the two flat-headed grinding discs 14;

[0055] Step 2, center the graphite electrode 41 that needs to be polished flat on the semicircle clamp 4, cover the semicircle cover 46, and screw the fastening bolts 48 respectively, the inner ends of each fa...
