Description

Technical Field

[0001] The utility model belongs to the technical field of grinders, and in particular relates to a cathode block grinding device based on an electron beam cold bed smelting furnace. Background Art

[0002] When using an electron beam cold hearth melting furnace to melt chemically active metals such as titanium and its titanium alloys, the kinetic energy of the electron beam generated by the electron gun is converted into heat energy to melt the molten material. The working principle of the electron gun is that a high-voltage electron beam is generated and formed between the anode and cathode blocks. When the electron gun is working, a high-voltage glow discharge with plasma burns between the cathode block and the hollow anode. The plasma is located in the anode cavity and is separated from the cathode block by a cathode potential drop zone. The plasma emits positive ions, which are accelerated in the cathode potential drop zone and bombard the cathode, thereby stimulating electron emission. The structure of the cathode block used in the electron gun of this melting furnace is as follows: Figure 2 As shown, the cathode block is a disc structure, a circular groove is provided in the middle of the outer circumference of the cathode block and a circular table is formed on both sides thereof, and circular holes are evenly distributed around the circular table on one side, and one end face of the cathode block is a concave arc end face for exciting and focusing electrons. To ensure the performance, the concave arc end face needs to be polished to make its surface smooth. The current polishing method for the concave arc end face is manual polishing, where a person holds sandpaper for polishing. This method is laborious to operate and has very low polishing efficiency. Therefore, it is necessary to propose improvements. Utility Model Content

[0025] The present embodiment is aimed at the grinding of the concave arc end face of the cathode block on the electron gun of the smelting furnace. Instead, the structure of the grinding wheel grinder is improved. The grinding wheel on the grinding wheel grinder is removed, and a disc-shaped cathode block connecting fixture 5 is fixed on the output shaft 4 of the double-headed motor 3. The cathode block 9 is coaxially connected to the outer side of the cathode block connecting fixture 5. The cathode block connecting fixture is driven to rotate by the double-headed motor, and the cathode block connecting fixture drives the cathode block to rotate. A person holds sandpaper on the concave arc end face of the cathode block, and grinding is achieved by friction between the rotation of the cathode block and the sandpaper. The person's hand moves according to the situation to complete the overall grinding of the concave arc end face on the cathode block. This structure is very convenient to use, saves time and effort, and improves work efficiency.

[0026] In a specific implementation: see Figure 1 , Figure 4 As shown, the center hole of the cathode block connecting tool 5 is tightly sleeved on the output shaft 4 of the double-headed motor 3 and connected by a flat key or a spline. The inner side of the cathode block connecting tool 5 is limited by an inner retaining ring 6 sleeved on the output shaft 4, and the outer side of the cathode block connecting tool 5 is limited by an outer retaining ring 7 sleeved on the output shaft 4 and fixed by a fixing nut 8 screwed with the output shaft 4.

[0027] Through the above structure, the cathode block connecting tooling 5 can be reliably connected to the output shaft 4 of the double-headed motor 3. This structure also adopts the connection structure of the original grinding wheel, so that the shape of the components on the grinder is not changed. It is only necessary to process the cathode block connecting tooling as required.

[0028] In a specific implementation: see Figure 1 As shown, a circular groove 5 - 1 is coaxially provided on the outer end surface of the cathode block connecting tool 5 , and the circular groove 5 - 1 makes the outer end surfaces of the outer retaining ring 7 and the fixing nut 8 lower than the outer end surface of the cathode block connecting tool 5 after installation.

[0029] Through the above structure, the outer end surface of the cathode block connecting tool 5 can be kept as a flush surface, ensuring that the two end surfaces of the cathode block 9 are tightly attached after being fixed.

[0030] In a specific implementation: see Figure 3 , Figure 4 , Figure 5 As shown, according to the position of the cathode block hole 9-3 at the edge of the cathode block 9, a plurality of cathode block connecting holes 5-2 are evenly distributed along the circumference of the cathode block connecting tooling 5, and the cathode block hole 9-3 of the cathode block 9 is connected to the cathode block connecting hole 5-2 by a connecting bolt 10.

[0032] In a specific implementation: see Figure 5 As shown, the cathode block connecting tool 5 is provided with a tool annular groove 5-3 on its outer circumferential surface, and the tool annular groove 5-3 forms circular connecting platforms 5-4 on both sides, and cathode block connecting holes 5-2 are evenly distributed on the circumference of the circular connecting platforms 5-4 on both sides.

[0033] Through the above structure, it can be ensured that both sides of the cathode block connecting tool 5 can be connected to the cathode block, and the two sides can be used interchangeably.

[0034] In a specific implementation: see Figure 1 As shown, a cathode block connecting fixture 5 is fixed on one output end of the double-headed motor 3 , and a grinding wheel 11 is fixed on the other output end of the double-headed motor 3 .

[0035] Through the above structure, one side of the grinder can be improved into a cathode block connecting tooling, so as to achieve both rapid grinding of the cathode block and guarantee the original grinding function of the grinder.

[0036] In a specific implementation manner: cathode block connecting fixtures 5 are fixed to both output ends of the double-headed motor 3 .

[0037] Through the above structure, cathode block connecting fixtures 5 are installed at both ends of the grinder, so that two cathode blocks can be grinded at the same time, which greatly improves the work efficiency.

[0038] In a specific implementation: see Figure 1 As shown, a fan-shaped protective cover 12 is provided on the two output end housings of the double-headed motor 3. This structure is used for protection during grinding work to avoid unnecessary safety hazards.
