[0025] See also Figure 1-5 A chip removal device for a cavity hole in a valve body comprises a tool storage base plate 1, a limited fixed seat 2 is arranged at the top of the tool storage base plate 1, a processing valve body 3 is arranged on the limited fixed seat 2, a tool support frame 4 is arranged on the side of the limited fixed seat 2, a tool drying component 5 is arranged at the bottom of the tool support frame 4, three fixed through holes 6 are evenly opened at the top of the tool support frame 4, a stepped double-edged rough boring tool 7, a high-pressure internal cooling water outlet tool 8 and a plunge milling tool 9 are respectively inserted in the fixed through holes 6, and a tool fixing block 10 is arranged at the top of the stepped double-edged rough boring tool 7, the high-pressure internal cooling water outlet tool 8 and the plunge milling tool 9.

[0026] The tool drying component 5 includes a drying and heating chamber 501 arranged below the fixed perforation 6, a plurality of air outlets 502 are evenly arranged at the top of the drying and heating chamber 501, a plurality of heating resistors 503 are symmetrically arranged in the drying and heating chamber 501, a mounting groove 504 is opened at the top of the tool storage base plate 1, a fan 505 is installed in the mounting groove 504, and an air inlet 506 is opened at the bottom of the mounting groove 504.

[0027] Two air inlets 506 are provided, and the two air inlets 506 are located on both sides of the fan 505 .

[0028] The tool support frame 4 is in an L-shape for accommodating the stepped double-edged rough boring tool 7 , the high-pressure internal cooling water outlet tool 8 and the plunge milling tool 9 .

[0029] Embodiment 2: The difference between this embodiment and embodiment 1 is that the bottom end of the tool fixing block 10 is larger than the opening of the fixing through hole 6 .

[0030] This enables the stepped double-edged rough boring tool 7, the high-pressure internal cooling water outlet tool 8 and the plunge milling tool 9 to be more stably inserted in the fixed through hole 6 without falling off.

[0031] Embodiment 3: The difference between this embodiment and embodiment 1 is that the air outlet 502 is located directly below the stepped double-edged rough boring cutter 7, the high-pressure internal cooling water outlet cutter 8 and the plunge milling cutter 9 respectively.

[0032] The hot air blown out of the air outlet 502 can be directly blown to the surfaces of the stepped double-edged rough boring tool 7, the high-pressure internal cooling water outlet tool 8 and the plunge milling tool 9 to dry the water stains on their surfaces after cleaning.

[0033] Embodiment 4: The difference between this embodiment and embodiment 1 is that two pointed conical air guide plates are symmetrically arranged on the top wall of the drying and heating chamber 501 .

[0034] The hot air heated by the fan 505 after blowing through the heating resistor 503 can quickly enter the air outlet 502 through the air guide plate.

[0035] In this embodiment, since the existing valve body center hole processing is mostly done by normal boring, the iron filings generated during the processing will be squeezed into the valve body center hole. At this time, the program needs to be paused in sections, and the employees can clean the iron filings in the center hole after retracting the tool. Such operation will disrupt the normal production rhythm, be inefficient, have high labor intensity for employees, and be prone to mistakes, resulting in an increase in product scrap rate, which is not conducive to safe production.

[0036] In summary, in the specific implementation, by arranging a processing valve body 3 on the tool storage base plate 1, the limiting fixing seat 2 can make the processing valve body 3 stably placed on the tool storage base plate 1 under the limit of the limiting fixing seat 2, and the stepped double-edged rough boring tool 7, the high-pressure internal cooling water outlet tool 8 and the insert milling tool 9 can be respectively inserted into the fixed perforation 6, thereby making it more convenient to take and place the stepped double-edged rough boring tool 7, the high-pressure internal cooling water outlet tool 8 and the insert milling tool 9.

[0037] When it is necessary to perform side milling on the processed valve body 3, the user needs to fix the processed valve body 3 on a turning and milling lathe, fix the processed valve body 3 by a clamp, and clamp the milling tool 9 on the lathe chuck, so that the milling tool 9 can mill six grooves in six equally divided directions on the inner wall of the middle cavity hole of the processed valve body 3, and then use the stepped double-edged rough boring tool 7 to bore the middle cavity hole to force chip breaking, so that the cut iron chips remain in the middle cavity hole, and then use the high-pressure internal cooling water outlet tool 8 to blow out the undischarged broken iron chips, thereby achieving the purpose of forced chip breaking and chip removal, which is stable, reliable and efficient.

[0038] This avoids the traditional processing technology of using a boring tool to bore from the center of the circle to the bottom, where the tool cannot break chips and is easily entangled with iron chips. By adopting an improved method, an eccentric six-point plug-in mode with the center of the circle as the reference, better chip breaking is achieved, the tool does not get entangled with chips, and the valve body processing technology is made more stable.

[0039] As for the tool drying assembly 5 arranged on the tool storage base plate 1, when the user has finished using the stepped double-edged rough boring tool 7, the high-pressure internal cooling water outlet tool 8 and the plunge milling tool 9, they can be respectively inserted into the fixed perforations 6 after cleaning, and the heating resistor 503 and the fan 505 in the tool drying assembly 5 can be connected to an external power supply, so that the heating resistor 503 can generate heat after being energized, and the fan 505 can generate wind after being energized, and the generated wind can blow upward.

[0040] The blown air flow is heated after passing through the heating resistor wire 503, thereby forming a hot air flow required for drying, and hot air is blown to the stepped double-edged rough boring tool 7, the high-pressure internal cooling water outlet tool 8 and the plunge milling tool 9 through the multiple air outlets 502, so that the processed stepped double-edged rough boring tool 7, the high-pressure internal cooling water outlet tool 8 and the plunge milling tool 9 can be dried faster, avoiding rust and corrosion caused by the retention of water stains, and making the stepped double-edged rough boring tool 7, the high-pressure internal cooling water outlet tool 8 and the plunge milling tool 9 use more long-term.
