[0032] The following further details the present application with reference to the accompanying drawings and through specific embodiments

[0033] A graphite washer processing device, as Figure 1 and Figure 2 shown, includes a workbench 1. A moving seat 2 and a milling cutter 3 are arranged on the workbench 1. A fixed frame 21 is arranged on the moving seat 2. The fixed frame 21 includes a mandrel 211 and a pressure plate 212. The pressure plate 212 is detachably connected to both ends of the mandrel 211 in the length direction. The mandrel 211 is for sleeving the graphite washer, and the pressure plate 212 is used to abut against the graphite washer. The milling cutter 3 is arranged corresponding to the position of the fixed frame 21 and is used for cutting the graphite washer. Specifically, during implementation, the mandrel 211 needs to be arranged corresponding to the inner ring of the graphite washer, which can reduce the up and down movement of the graphite washer after installation. When cutting, multiple graphite washers need to be installed on the mandrel 211 at the same time, and by moving a file along the mandrel 211, multiple graphite washers on the mandrel 211 can be cut, completing the cutting of multiple graphite washers at one time, thereby improving production efficiency

[0034] As Figure 1 and Figure 2 shown, a first moving frame 22 and a second moving frame 23 are arranged on the moving seat 2. The first moving frame 22 is slidably connected to the moving seat 2, and the first moving frame 22 can move towards the milling cutter 3. The second moving frame 23 is slidably arranged on the first moving frame 22, and the second moving frame 23 slides perpendicular to the sliding direction of the first moving frame 22

[0035] As Figure 1 and Figure 2As shown, a placement table 231 is fixedly provided on the second movable frame 23, and the placement table 231 is provided on a side close to the milling cutter 3. The placement table 231 is provided for the fixed frame 21 to be placed. The cross section of the pressing plate 212 is provided in a square shape, and the four sides of the pressing plate 212 are provided with a clearance groove 215 for the milling cutter 3 to pass through. In specific implementation, the pressing plate 212 can be changed in direction by flipping, so that the graphite gasket can be processed in all directions, and the clearance groove 215 can make way for the milling cutter 3. The milling cutter 3 in this embodiment is disc-shaped, so the clearance groove 215 is provided corresponding to its shape and position. When processing, the milling cutter 3 moves along the position of the clearance groove 215 to process the required slots on multiple graphite gaskets at one time, thereby realizing the simultaneous processing of multiple graphite gaskets.

[0036] like Figure 1 and Figure 2 As shown, the second movable frame 23 is also provided with a guide plate 232 corresponding to the placement table 231. The guide plate 232 is arranged perpendicular to the placement table 231 and arranged along the length direction of the placement table 231. The guide plate 232 is used to abut the pressing plate 212. A guide bar 233 is arranged on the side of the placement table 231 away from the guide plate 232. The guide bar 233 is fixedly connected to the placement table 231, and the guide bar 233 is used to abut the pressing plate 212. In specific implementation, when the milling cutter 3 is processing, the guide bar 233 cooperates with the guide plate 232 to limit the displacement of the fixed frame 21, thereby reducing the displacement of the fixed frame 21. Since the graphite material is relatively soft, the milling cutter 3 can cut it more easily during cutting, so the fixed frame 21 will not be displaced during the cutting process.

[0037] like Figure 1 and Figure 2 As shown, the movable seat 2 is provided with a screw rod 24, which is rotatably connected with the movable seat 2, and the screw rod 24 is threadedly connected with the first movable frame 22, and the movable seat 2 is provided with a convex strip 25 toward the first movable frame 22, and the first movable frame 22 is correspondingly provided with a groove 221, and the convex strip 25 is embedded in the groove 221. The first movable frame 22 is also rotatably provided with a screw rod 24, and the screw rod 24 on the first movable frame 22 is threadedly connected with the second movable frame 23, and the first movable frame 22 is also provided with a convex strip 25 toward the second movable frame 23, and the second movable frame 23 is correspondingly provided with a groove 221. In specific implementation, since the convex strip 25 is embedded in the groove 221, the first movable frame 22 and the second movable frame 23 cannot rotate, so when the screw rod 24 rotates, the first movable frame 22 and the second movable frame 23 can only slide along the corresponding screw rod 24, thereby changing the position of the fixed frame 21, reducing the situation where the fixed frame 21 is pushed and tilted by the milling cutter 3 during the movement, and further improving the stability of the processing.

[0038] like Figure 1 and Figure 2As shown, a handwheel 241 is provided on the lead screw 24. The handwheel 241 is arranged at the end of the lead screw 24 and fixedly connected to the lead screw 24. During specific implementation, rotating the two handwheels 241 can adjust the position of the fixing bracket 21.

[0039] As Figure 1 and Figure 2 shown, threaded sections 213 are provided at both ends of the mandrel 211. Nuts 214 are threadedly connected to the threaded sections 213, and the nuts 214 are used to abut against the pressing plate 212. During specific implementation, when the number of graphite washers placed is different, the position of the nut 214 can be adjusted according to the situation to improve versatility.

[0040] As Figure 1 and Figure 2 shown, a dust suction pipe 4 is further provided on the workbench 1. The dust suction pipe 4 is arranged beside the milling cutter 3 and is used to suck graphite chips.

[0041] Working principle: Install the graphite washer on the fixing bracket 21, then place the fixing bracket 21 on the placing table 231, adjust the first moving bracket 22 so that the milling cutter 3 is aligned with the graphite washer, start the milling cutter 3 and adjust the second moving bracket 23 so that the graphite washer moves towards the milling cutter 3, thereby completing the processing.

[0042] The above are the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
