Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, specifically to a multi-spindle precision CNC machine tool. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] During the machining process, the operator needs to process the workpiece through the control window, which makes it impossible to clean up the generated chips in time. As a result, some chips enter the rotating structure of the machine tool, affecting the normal rotation of the machine tool and thus affecting the machining effect of the workpiece.

[0004] Therefore, it is essential to design a multi-spindle precision CNC machine tool that is highly practical and can automatically clean up the chips generated during the machining process of the workpiece. Summary of the Invention

[0020] This invention, through the second water guide ring, water guide fixing box, clamp, protective cover, outer sleeve, arc-shaped elastic connecting pipe, tortuous water guide plate, triangular cleaning block, connecting column, and I-shaped electromagnetic block set in the first cleaning mechanism, enables the triangular cleaning block to clean the surface of the fixed base plate while preventing strip-shaped chips from getting entangled on the surface of the triangular cleaning block during the cleaning process, thereby affecting the subsequent cleaning effect of the triangular cleaning block on the surface of the fixed base plate.

[0021] This invention, through a water storage box, magnetic pressure plate, water spray cleaning pipe, fixed ring, and arc-shaped bladder set in the second cleaning mechanism, enables the rotating pallet to clean the chips accumulated in the gap between the rotating pallet and the fixed base plate during rotation under the action of water flow and magnetic force, preventing excessive chip accumulation between the rotating pallet and the fixed water tank from affecting the normal rotation of the rotating pallet.

[0035] Please see Figure 2-5 The first cleaning mechanism 4 includes:

[0036] A fixed base plate 401 is provided, with a water guide ring 402 passing through the bottom of the middle part of the fixed base plate 401.

A water inlet is provided on the inner side of the first water guide ring 404 near the front and rear sides. The length of the water outlet is less than the length of the water inlet. Magnetic blocks are provided on the front and rear sides of the arc-shaped triangular parts on the left and right sides of the rotating support plate 3.

[0037] Multiple square nozzles are fixedly connected to the outer side of the first water guide ring 404. The square nozzles are connected to the first water guide ring 404. The square nozzles are placed in the strip groove on the surface of the fixed base plate 401. The top of the second water guide ring 405 is connected to the water guide fixing box 406 through the arc-shaped conduit. The middle of the left and right sides of the water guide fixing box 406 is fixedly connected to the second arc-shaped conduit.

[0038] The second cleaning mechanism 5 also includes a protective cover 408 fixedly connected between the top of the water guide fixing box 406 and the outer edge of the second water guide ring 405. An outer sleeve 409 is fixedly connected to the middle of the outer side of the clamp 407. An arc-shaped elastic connecting tube 410 is provided inside the outer sleeve 409. A triangular cleaning block 412 is fixedly connected to the bottom of the outer sleeve 409 and the arc-shaped elastic connecting tube 410. A curved water guide plate 411 is fixedly connected to the inner right side of the triangular cleaning block 412. A connecting... The connecting column 413 has an I-shaped electromagnetic block 414 slidably connected to it. An arc-shaped elastic connecting tube 410 and a clamp 407 are fixedly connected. The outer sleeve 409 and the bottom end of the arc-shaped elastic connecting tube 410 are fixedly connected to a triangular cleaning block 412 via a hinge. A strip-shaped channel is provided near the right side inside the triangular cleaning block 412, and a second strip-shaped channel is provided to the left of the strip-shaped channel. The middle part of the water guide fixing box 406 is connected to the strip-shaped channel near the top via the second arc-shaped conduit. A tortuous water guide plate 41... 1. The top and bottom of the strip channel are fixedly connected. The connecting column 413 is fixedly connected to the top of the second strip channel. The I-shaped electromagnetic block 414 is I-shaped. The I-shaped electromagnetic block 414 passes through the connecting column 413 and is slidably connected to the connecting column 413. The bottom of the I-shaped electromagnetic block 414 is uniformly fixedly connected with a support spring. The bottom end of the I-shaped electromagnetic block 414 is divided into an electromagnet block. The left and right sides of the second strip channel are provided with circular channels near the top and bottom. The circular channels are connected to the second strip channel. The lower circular channel is uniformly fixedly connected with multiple first water spray channels on the side away from the I-shaped electromagnetic block 414. The part of the first water spray channel located outside the triangular cleaning block 412 is inclined downward. The upper circular channel is uniformly fixedly connected with multiple second water spray channels on the side away from the I-shaped electromagnetic block 414. The part of the second water spray channel located outside the triangular cleaning block 412 is inclined towards the side of the triangular cleaning block 412 away from the clamp 407. The triangular cleaning block 412 is made of non-metallic material.

[0039] During the processing of the workpiece, the water supply device 6 is activated to supply water into the water guide ring 402. The water entering the water guide ring 402 flows through the second water guide ring 405 and the arc-shaped conduit into the water guide fixing box 406. The water entering the water guide fixing box 406 flows through the second arc-shaped conduit into the outer sleeve 409. As the rotating base 403 drives the workpiece to rotate through the water guide fixing box 406 and the clamp 407, the clamp 407 drives the triangular cleaning block 412 to rotate through the outer sleeve 409. When the triangular cleaning block 412 is placed on the top of the fixed base plate 401, it is attracted to the top of the fixed base plate 401 by magnetic force. This allows the triangular cleaning block 412 to clean the chips accumulated on the top of the fixed base plate 401 during its rotation. When the triangular cleaning block 412 moves with the clamp 407 and causes the I-shaped electromagnetic block 414 to detach from the top of the fixed base plate 401, the magnetic force on the triangular cleaning block 412 disappears. At this point, the triangular cleaning block 412 operates under the elasticity of the arc-shaped elastic connecting tube 410 and the hinge. When the triangular cleaning block 412 separates from the surface of the fixed base plate 401, it tilts downward at a certain angle on the left side. At this time, the I-shaped electromagnetic block 414 resets under the action of the support spring and blocks the circular channel below, so that the water flowing into the strip channel enters the circular channel above and is sprayed out through the second water spray channel to impact and clean the cutting chips wrapped around the surface of the triangular cleaning block 412. At the same time, the water flowing into the strip channel impacts the tortuous water guide plate 411, causing the triangular cleaning block 412 to shake continuously, thereby further enhancing the cleaning of the cutting chips wrapped around the surface of the triangular cleaning block 412. When the second water guide ring 405 rotates and the drain outlet and water inlet are aligned, the water flowing in the second water guide ring 405 enters the first water guide ring 404. The water flows through the square spray pipe to rinse the strip groove on the surface of the fixed base plate 401, preventing too many chips from accumulating in the strip groove on the surface of the fixed base plate 401 and affecting the cleaning effect of the chips on the surface of the fixed base plate 401.

[0040] Please see Figure 6-8The second cleaning mechanism 5 includes water storage boxes 501 located on the front and rear sides of the left and right sides of the rotating pallet 3. A magnetic pressure plate 502 is slidably connected to the side of the water storage box 501 facing the rotating pallet 3. Multiple water spray cleaning pipes 503 pass through the magnetic pressure plate 502. A fixing ring 504 is fixedly connected to the outer side of the arc-shaped triangular part on the left and right sides of the rotating pallet 3. An arc-shaped bladder 505 is provided on the outer side of the upper half of the fixing ring 504. A limiting spring is provided on the outer side of the part of the water spray cleaning pipe 503 placed between the water storage box 501 and the magnetic pressure plate 502. A limiting tube is fixedly connected to the part of the water spray cleaning pipe 503 placed on the outer side of the magnetic pressure plate 502. The number of water spray cleaning pipes 503 located on the rear side of the rotating pallet 3 is less than the number of water spray cleaning pipes 503 located on the front side of the rotating pallet 3. The water storage box 501 is connected to the fixed water tank 2 through a one-way water inlet pipe. The bottom end of the fixing ring 504 is fixedly connected to the bottom end of the fixed water tank 2 through a fixing rod.

[0041] The second cleaning mechanism 5 also includes a sliding frame 506 fixedly connected to the fixed water tank 2 near its top. An inclined scraper 507 is slidably connected to the middle of the sliding frame 506. A push bladder 508 is provided on the outer side of the portion of the sliding frame 506 between the inclined scrapers 507. A water spray cleaning block 509 is fixedly connected to the top of the inclined scraper 507. A water storage bladder 510 is fixedly connected to the top of the fixed water tank 2. An arc-shaped bladder 505 is divided into left and right sides. The arc-shaped bladder 505 is connected to the push bladder 508 through a hose. The water spray cleaning block 509 has downward-sloping nozzles on one side facing the front and rear of the fixed water tank 2. The part of the inclined scraper 507 near the top is fixedly connected to the water storage tank 510 through a bracket. The water storage tank 510 is connected to the inclined scraper 507 through a water guide hose. The magnetic block inside the rotating support plate 3 and the magnetic pressure plate 502 are magnetically identical. The bottom end of the water storage tank 510 is connected to the fixed water tank 2 through a one-way water inlet pipe.

[0042] During rotation, the rotating bracket 3 compresses the arc-shaped bladder 505, forcing air from inside the bladder into the pushing bladder 508, causing the pushing bladder 508 to extend and push the inclined scraper 507 to move. This movement of the inclined scraper 507 scrapes and cleans the fixed water tank 2. As the inclined scraper 507 moves, it compresses the water storage bladder 510 via the bracket, forcing water from the storage bladder 510 to flow through the inclined scraper 507 into the water spray cleaning block 509, from which it is sprayed to rinse the surface of the fixed water tank 2, thus enhancing the cleaning effect. When the rotating bracket rotates to the other side, the inclined scraper 507 gradually returns to its original position. During this return process, the inclined scraper 507 scrapes the surface of the fixed water tank 2 again. Simultaneously, as the inclined scraper 507 moves away from the center of the fixed water tank 2, it cleans any fallen solid water. The chips on the surface of the fixed water tank 2 are scraped and accumulated between the inclined scrapers 507 for easy centralized cleaning when the work stops. During the movement of the rotating pallet 3, the magnetic pressure plate 502 is weakened by the magnetic force inside the rotating pallet 3, causing the magnetic pressure plate 502 to reset. During the reset process, the water in the fixed water tank 2 is drawn into the water storage box 501. After the rotating pallet 3 is reset, the magnetic pressure plate 502 moves to the front and rear sides of the fixed water tank 2 under the influence of the magnetic force, filling the water in the water storage box 501 into the water spray cleaning pipe 503 and spraying it out from the water spray cleaning pipe 503 to rinse the left and right sides of the rotating pallet 3. The number of water spray cleaning pipes 503 is set to prevent convection from forming between the front and rear sides of the rotating pallet 3 during the cleaning process, which would affect the cleaning effect on the left and right sides of the rotating pallet 3.
