The sides of the two mounting grooves 5c-7 are respectively recessed inward to form fan-shaped tables 5c-10.

[0037] Since the upper and lower sides of the tool 5c-8 are symmetrically provided with an arc-shaped working surface 5c-9, the two tool seats 5c-5 can share the tool 5c-8 by interference fitting the tool 5c-8 in the installation groove 5c-7 that intersects the upper and lower tool seats 5c-5, and the waste chips scraped off by the tool 5c-8 at the end of the electrode cap are discharged through the chip discharge port 5c-6.

[0038] In this embodiment, the blowing mechanism 4 also includes a chip blowing box 4e which is sleeved on the outside of the second mounting hole 5a-7 and the third mounting hole 5a-9.

The two plastic shielding sheets 4e-2 are respectively provided with plug-in holes 4e-3 at positions corresponding to the fan-shaped platform 5c-10.

[0041] The air inlet connector 4c on the air inlet pipe 4a is connected to an external air source, and compressed air is introduced into the air amplifier 4e-6 (an existing device, the principle of which will not be repeated here). The compressed air introduced into the air amplifier 4e-6 serves as a power source, which can drive the surrounding air to flow to form a high-pressure, high-speed airflow and generate suction. When the grinding mechanism 5 is working, the operator operates the PLC controller to control the opening of the solenoid valve 4b, and the gas enters the air inlet pipe 4f-1 from the two air outlet connectors 4d-1 on the connecting pipe 4d, and finally enters the blowing pipe 4f-2 on the blowing connector 4f to blow toward the tool holder 5c-5, blowing the waste chips away from the tool holder 5c-5. At this time, the waste chips are sucked into the air amplifier 4e-6 under the action of the suction generated by the air amplifier 4e-6, and enter the waste chip collection box 1 along the feed pipe 4e-7.

[0042] In this embodiment, a plurality of exhaust holes 1b are provided on the upper portion of the side wall of the waste collecting box 1, a discharge port 1c is provided on the lower portion of the side wall of the waste collecting box 1, and a collecting box 1d is provided in the discharge port 1c.

[0044] In this embodiment, the first fixing member 6 includes two L-shaped plates 6a fixed to the upper and lower parts of the back side of the control box 3, and waist holes 6a-1 are opened on both sides of the two L-shaped plates 6a. One side of the two L-shaped plates 6a is provided with a fixing plate 6b and an arc strip 6c clamped on both sides of the column 2. A first through hole is opened on both sides of the fixing plate 6b, and a protrusion 6b-2 adapted to the outer wall of the column 2 is set in the middle of the fixing plate 6b. Threaded columns 6d are set at both ends of the arc strip 6c. The two threaded columns 6d pass through the first through hole and the waist hole 6a-1 respectively and are threadedly connected with the nut 6e.

[0045] The two threaded columns 6d respectively pass through the first through holes on both sides of the fixing plate 6b and the waist holes 6a-1 on both sides of the L-shaped plate 6a and are threadedly connected with the nuts 6e, so that the control box 3 can be fixed to one side of the column 2.

[0046] In this embodiment, the second fixing member 7 includes a first clamping block 7a and a second clamping block 7b clamped on both sides of the column 2. The first clamping block 7a and the second clamping block 7b respectively form arc-shaped notches that are compatible with the outer wall of the column 2 toward the side edges of the column 2. Second through holes are respectively provided on both sides of the first clamping block 7a. A threaded hole 7b-1 is provided at a position corresponding to the second through hole of the second clamping block 7b.

A fixing block 7d is provided on the side wall of the connecting block 5a-1, and the second clamping block 7b is fixedly connected to the fixing block 7d.

[0047] The bolt 7c penetrates through the second through hole and is threadedly connected with the threaded hole 7b - 1 , clamping the first clamping block 7a and the second clamping block 7b on both sides of the column 2 , so that the grinding mechanism 5 is fixed on one side of the column 2 .

[0048] Working principle: The present application cooperates with an external robot arm (not shown in the drawings of the specification), and the external robot arm clamps two upper and lower electrode caps. The heads of the two electrode caps are respectively inserted into the plug holes 4e-3 on the plastic shielding sheet 4e-2 until they are against the fan-shaped table 5c-10, and the air intake connector 4c on the air intake pipe 4a is connected to the external air source, and compressed air is introduced into the air amplifier 4e-6 (which is an existing device and the principle is not repeated here). The compressed air introduced into the air amplifier 4e-6 serves as a power source, which can drive the surrounding air to flow to form a high-pressure and high-speed airflow and generate suction. The operator operates the PLC controller in the control box 3 to control the opening of the solenoid valve 4b and the rotating motor 5b. Since the upper and lower sides of the tool 5c-8 are symmetrically provided with the working surface 5c-9 of the arc-shaped curved surface structure, it is only necessary to install the tool 5c-8 in the installation groove 5c-7 that intersects the upper and lower tool seats 5c-5. 8, the two tool holders 5c-5 can share the tool 5c-8, and the ends of the two electrode caps inserted into the plug hole 4e-3 respectively contact the working surfaces 5c-9 on the upper and lower sides of the tool 5c-8, and the two electrode caps are ground together under the rotation of the tool 5c-8, which improves the grinding efficiency. When the electrode caps are ground, the gas provided by the external air source enters the air inlet pipe 4f-1 through the two air outlet joints 4d-1 on the connecting pipe 4d, and finally enters the air blowing pipe 4f-2 on the air blowing joint 4f to blow toward the tool holder 5c-5, so that the waste chips ground by the electrode caps are blown away from the tool holder 5c-5. When the waste chips are blown up, they are sucked into the air amplifier 4e-6 under the suction force generated by the air amplifier 4e-6, and enter the waste chip collection box 1 along the feed pipe 4e-7. The airflow coming in from the feed pipe 4e-7 is discharged through a number of exhaust holes 1b, leaving only the waste chips falling into the collection box 1d under the action of gravity and being collected.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
