Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer toFigure 1-7 , the present invention provides a technical solution: a turning device for a flange with a precise positioning structure. A clamping and rotating mechanism 2 is installed on one side of the top of the processing table 1, and a lead screw mechanism 3 is rotatably arranged on the top of the processing table 1.

[0036] Specifically, the clamping and rotating mechanism 2 includes a second drive motor 201, and the second drive motor 201 is installed on one side of the first fixing plate 202. The second drive motor 201 can drive a rotating rod 204 arranged inside the protective box 203 to rotate, and one end of the rotating rod 204 is connected to an encoder 205. A first gear 206 is fixedly installed on the outer side of the rotating rod 204, and the first gear 206 meshes with a second gear 207. The second gear 207 is installed on the outer side of a transmission rod 208, and one end of the transmission rod 208 is connected to a clamping disc 209. By setting the encoder 205, it is convenient to detect the rotation angle of the clamping disc 209 in a timely manner, so as to achieve the precise rotation positioning of the flange. When in use, the second drive motor 201 is turned on. Under the action of the second drive motor 201, the rotating rod 204 rotates. The encoder 205 detects the rotation angle of the rotating rod 204. The rotating rod 204 drives the second gear 207 and the transmission rod 208 to rotate synchronously through the first gear 206, and the transmission rod 208 drives the clamping disc 209 to rotate synchronously.

[0037] Furthermore, the clamping disc 209 is installed on one side of the second fixing plate 2091, and the clamping disc 209 is rotatably connected to the second fixing plate 2091. The clamping disc 209 can clamp and limit the flange. The clamping disc 209 is a prior art and will not be described in detail. For the specific structure, reference can be made to the relevant description in CN217452158U, a fixture for turning a flange.

[0038] Specifically, the cooling and chip-clearing turning tool mechanism 4 includes a first mounting box 401, and the first mounting box 401 is connected to an annular air pipe 4011 through a connecting pipe. The annular air pipe 4011 is installed outside the first mounting box 401, and several groups of inclined air outlets 4012 are installed on the outside of the annular air pipe 4011. A first driving motor 402 is installed inside the first mounting box 401, and the first driving motor 402 is connected to a gear acceleration mechanism 5. The gear acceleration mechanism 5 can drive a rotating cylinder 403 arranged inside the first mounting box 401 to rotate, and one end of the rotating cylinder 403 is connected to a turning tool 404 arranged outside the first mounting box 401. The turning tool 404 is located inside the annular air pipe 4011. A driving wheel 405 is fixedly arranged on the outside of the rotating cylinder 403, and the driving wheel 405 is connected to a driven wheel 601 arranged inside a second mounting box 6 through a transmission belt 406. The driven wheel 601 is installed on the outside of a driving rod 602, and rotating fan blades 603 are symmetrically installed on the outside of the driving rod 602. The second mounting box 6 is connected to a cooling box 7 through a first delivery pipe 604, and a refrigeration mechanism 701 is installed inside the cooling box 7. The cooling box 7 is connected to the inside of the first mounting box 401 through a second delivery pipe 702.

[0039] In a further embodiment, the gear acceleration mechanism 5 includes a support box 501, and the first driving motor 402 can drive a first rotating rod 502 rotatably arranged inside the support box 501 to rotate. A third gear 503 is fixedly installed on the outside of the first rotating rod 502, and the third gear 503 meshes with a fourth gear 504. The fourth gear 504 is installed on the outside of a second rotating rod 505, and a fifth gear 506 is arranged on the outside of the second rotating rod 505. The fifth gear 506 meshes with a sixth gear 507, and the sixth gear 507 is installed on the outside of a third rotating rod 508. One end of the third rotating rod 508 is connected to the rotating cylinder 403.

[0040] In a further embodiment, the size of the third gear 503 is larger than that of the fourth gear 504. When the third gear 503 rotates, it can drive the fourth gear 504 to rotate at an accelerated speed. The size of the fifth gear 506 is larger than that of the sixth gear 507. When the fifth gear 506 rotates, it can drive the sixth gear 507 to rotate at an accelerated speed.

[0041] Further explanation, the rotating cylinder 403 is rotatably connected to a stabilizing plate 8 arranged inside the first mounting box 401. By arranging the stabilizing plate 8, the stability of the rotating cylinder 403 during rotation can be improved.

[0042] Specifically, several groups of moisture-absorbing cotton strips 703 are arranged at intervals on the inner wall of the cooling box 7. The temperature inside the cooling box 7 is relatively low, and the moisture in the gas will condense into water droplets on the inner wall of the box. The moisture-absorbing cotton strips 703 can absorb the water droplets.

[0043] Specifically, the refrigeration mechanism 701 includes a thermoelectric cooler 7011, and the refrigerating surface of the thermoelectric cooler 7011 is connected to a refrigerating plate 7012 arranged inside the cooling box 7. A plurality of groups of temperature guiding plates 7013 are installed on one side of the refrigerating plate 7012. The heating surface of the thermoelectric cooler 7011 is connected to a heat conducting plate 7014, and the other side of the heat conducting plate 7014 is connected to a heat sink 7015. A heat dissipation fan 7016 which is used in cooperation with the heat sink 7015 is installed on one side of the heat sink 7015.

[0044] When it is necessary to cool the inside of the cooling box 7, the thermoelectric cooler 7011 and the heat dissipation fan 7016 are turned on. The low temperature of the refrigerating surface of the thermoelectric cooler 7011 is conducted to the inside of the cooling box 7 through the refrigerating plate 7012 and the temperature guiding plates 7013, and the high temperature of the heating surface of the thermoelectric cooler 7011 is discharged through the heat conducting plate 7014, the heat sink 7015 and the heat dissipation fan 7016.

[0045] During processing, the third driving motor 303 is turned on. Under the action of the third driving motor 303, the lead screw mechanism 3 rotates to drive the connecting block 302 and the turning tool 404 to move, so that the turning tool 404 continuously approaches the flange of the clamping and rotating mechanism 2. The first driving motor 402 and the refrigeration mechanism 701 are turned on. The refrigeration mechanism 701 can cool the inside of the cooling box 7. Under the action of the first driving motor 402, the first rotating rod 502 rotates. The first rotating rod 502 drives the fourth gear 504 and the second rotating rod 505 to rotate through the third gear 503. Under the action of the rotation of the second rotating rod 505, the fifth gear 506 drives the sixth gear 507 and the third rotating rod 508 to rotate, so as to drive the rotating cylinder 403 and the turning tool 404 to rotate. At the same time, under the action of the rotation of the rotating cylinder 403, the driving wheel 405 drives the driven wheel 601 and the driving rod 602 to rotate through the transmission belt 406, so that the rotating fan blade 603 rotates to blow air. The air generated by the rotation of the rotating fan blade 603 enters the inside of the cooling box 7 for cooling. The cooled air enters the first installation box 401 to cool the first driving motor 402, and finally the cooled air is discharged through the inclined air outlet 4012. The cooled air discharged from the inclined air outlet 4012 can cool the turning tool 404 and can also blow and clean the debris at the processing position.
