[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figures 1 to 9 The present invention provides a technical solution: a CNC machine tool oil pump oil supply device, including an oil supply housing 1, a circulating oil pump 2 is fixedly connected to the top of the oil supply housing 1, an oil delivery pipe 3 is fixedly connected to the upper part of the inner wall of the oil supply housing 1, and the top of the oil delivery pipe 3 is fixedly connected to the oil discharge end of the circulating oil pump 2.

[0019] A material collecting bin 4 is provided in the middle of the inner wall of the oil feeder housing 1, and the bottom of the oil delivery pipe 3 extends to the interior of the material collecting bin 4. A transmission bin 8 matching the material collecting bin 4 is provided at the lower part of the inner wall of the oil feeder housing 1, and a transmission mechanism 5 is movably connected between the interior of the transmission bin 8 and the interior of the material collecting bin 4.

[0020] A filtering mechanism 6 that cooperates with the transmission mechanism 5 is movably connected between the inner wall of the oil delivery pipe 3 and the inner wall of the material collecting bin 4. It should be noted that the top surface of the inner wall of the material collecting bin 4 is set as an inclined surface to facilitate the discharge of iron filings.

[0021] The lower part of the inner wall of the oil delivery pipe 3 is fixedly connected with an L-shaped oil discharge pipe 7. It should be noted that the oil inside the oil delivery pipe 3 is discharged from the L-shaped oil discharge pipe 7.

[0022] In this embodiment, Figures 1 to 9 As shown, the transmission mechanism 5 includes a friction sleeve 501, which is slidably connected to the lower part of the inner wall of the transmission bin 8. An adjusting column 502 is movably sleeved in the middle part of the friction sleeve 501. A spiral groove 503 is provided on the surface of the adjusting column 502. An adjusting pin 504 is fixedly connected to the middle part of the inner wall of the friction sleeve 501. The adjusting pin 504 is slidably connected to the inside of the spiral groove 503. A limit pin 505 is symmetrically fixedly connected to the upper part of the adjusting column 502. The limit pin 505 is slidably connected to the upper part of the transmission bin 8.

[0023] A mounting groove 506 is provided on the side wall at the lower part of the transmission bin 8, and an electric telescopic rod 507 is fixedly connected inside the mounting groove 506. A connecting block 508 is slidably connected between the inner wall of the mounting groove 506 and the inner wall of the transmission bin 8. One side of the connecting block 508 is fixedly connected to the side wall of the friction sleeve 501, and the other side of the connecting block 508 is fixedly connected to the movable end of the electric telescopic rod 507. It should be noted that: when the connecting block 508 rises between the installation groove 506 and the transmission chamber 8, the friction sleeve 501 can bring the limit pin 505 on the adjusting column 502 to rise to the inner top surface position on the inner wall of the transmission chamber 8. At this time, as the friction sleeve 501 continues to rise, the adjusting pin 504 inside the friction sleeve 501 cooperates and slides with the spiral groove 503 on the surface of the adjusting column 502, so that the adjusting column 502 rotates with the Y-shaped bracket tube 509; through the friction effect of the friction sleeve 501, the friction sleeve 501 can move up and down with the adjusting column 502; and a timer is provided at the position of the electric telescopic rod 507, so that the electric telescopic rod 507 starts to extend and retract at a fixed time. The cooperation between the timer and the electric telescopic rod 507 is a prior art and will not be described in detail here.

[0024] The top of the adjusting column 502 is fixedly connected to a Y-shaped bracket tube 509, the upper part of the Y-shaped bracket tube 509 passes through the transmission bin 8 and extends to the interior of the aggregate bin 4, and the middle part of the Y-shaped bracket tube 509 is movably interspersed with a Y-shaped connecting rod 510, and the top of the Y-shaped connecting rod 510 and the top of the Y-shaped bracket tube 509 are both fixedly connected to the lower part of the filtering mechanism 6.

[0025] A through slot 511 is provided in the middle of the Y-shaped connecting rod 510, and a cross bar 512 is slidably connected inside the through slot 511. The cross bar 512 is arranged on the upper part of the Y-shaped bracket tube 509, and both ends of the cross bar 512 are slidably connected to vertical bars 513, and the vertical bars 513 are fixedly connected to the inner top surface of the aggregate bin 4. It should be noted that the through slot 511 cooperates with the cross bar 512, so that the Y-shaped bracket tube 509 can move up synchronously with the cross bar 512 during the rising process, avoiding interference with the Y-shaped connecting rod 510, and under the restriction of the vertical bar 513, the Y-shaped bracket tube 509 will not rotate synchronously with the cross bar 512 and the Y-shaped connecting rod 510 during the rotation process.

[0026] In this embodiment, Figures 1 to 9 As shown, the transmission chamber 8 is set as a T-slot, and the top and bottom of the limit pin 505 are fixedly connected with balls, and the limit pin 505 overlaps the surface of the upper part of the transmission chamber 8 through the balls. It should be noted that the friction resistance of the adjustment column 502 during the rotation process inside the transmission chamber 8 is reduced by setting the balls.

[0027] In this embodiment, Figures 1 to 9 As shown, the filtering mechanism 6 includes an adjusting tube 601, which is movably inserted into the lower part of the inner wall of the oil delivery pipe 3, and the side wall of the lower part of the adjusting tube 601 is fixedly connected to the upper part of the transmission mechanism 5. An adjusting ring 602 is overlapped inside the adjusting tube 601, and the bottom of the adjusting ring 602 is fixedly connected to the upper part of the transmission mechanism 5. It should be noted that: the lower part of the outer wall of the adjusting tube 601 is fixedly connected to the top of the Y-shaped bracket tube 509, and the bottom of the adjusting ring 602 is fixedly connected to the top of the Y-shaped connecting rod 510; the outer ring of the adjusting ring 602 is fitted with the inner wall of the adjusting tube 601 to form a sealed state.

[0028] The top of the adjusting tube 601 and the top of the adjusting ring 602 are both movably connected with a sealing mechanism 603. The two sealing mechanisms 603 are different in size and are arranged in opposite directions. It should be noted that when the sealing mechanism 603 at the top of the adjusting tube 601 is in an open state, the sealing mechanism 603 at the top of the adjusting ring 602 is in a sealed state.

[0029] In this embodiment, Figures 1 to 9As shown, the sealing mechanism 603 includes a sealing bearing 6031, which is fixedly connected to the top of the adjusting tube 601. A sealing cone ring 6032 is fixedly connected to the top of the sealing bearing 6031. The inner bottom surface of the sealing cone ring 6032 is connected to five sealing plates 6033 that are equidistantly rotated along the circumference. A groove 6034 is provided on the side wall of the sealing plate 6033. A pull rod 6035 is hinged inside the groove 6034. One end of the pull rod 6035 is hinged to the top of the adjusting tube 601. It should be noted that: a rotating shaft is set at the bottom of the sealing cone ring 6032, and the sealing plate 6033 is rotatably connected to the surface of the rotating shaft. The five sealing plates 6033 form a disc shape to seal the middle position of the sealing cone ring 6032, and the sealing plate 6033 can effectively seal the bottom of the sealing cone ring 6032 and the top of the adjusting tube 601; the pull rod 6035 at the adjusting ring 602 is hinged to the bottom of the sealing cone ring 6032 inside the adjusting ring 602, and the sealing plate 6033 at the adjusting ring 602 is rotatably connected to the top of the adjusting ring 602; and the setting direction of the sealing plate 6033 at the adjusting ring 602 is opposite to the setting direction of the sealing plate 6033 at the adjusting tube 601. When the adjusting tube 601 rotates forward, the upper sealing plate 6033 opens, and when the adjusting tube 601 reverses, the sealing plate 6033 at the adjusting ring 602 opens.

[0030] A return spring 6036 is fixedly connected between the bottom of the sealing cone ring 6032 and the surface of the sealing plate 6033. It should be noted that the return spring 6036 of the adjustment ring 602 is arranged between the top of the adjustment ring 602 and the corresponding sealing plate 6033, and the return spring 6036 is set as a torsion spring and can be automatically reset.

[0031] The top of the sealing cone ring 6032 is fixedly connected with four tooth blocks 6037 at equal intervals along the circumference, and the upper part of the inner wall of the oil delivery pipe 3 and the upper part of the inner wall of the regulating tube 601 are fixedly connected with tooth rings 6038 that match the corresponding tooth blocks 6037. It should be noted that: when the tooth block 6037 at the top of the regulating tube 601 is engaged with the corresponding tooth ring 6038, the regulating column 502 and the limit pin 505 move up to the limit position inside the transmission chamber 8; when the regulating tube 601 moves down, the tooth block 6037 at the top of the regulating tube 601 is released from the engaged state and reset under the action of the reset spring 6036; then the regulating tube 601 that moves down, with the internal tooth ring 6038, engages with the tooth block 6037 at the top of the regulating ring 602, and at this time, when the regulating tube 601 rotates, the sealing mechanism 603 inside the regulating tube 601 opens.

[0032] In this embodiment, Figures 1 to 9As shown, the outer wall of the regulating tube 601 is fixedly connected with a sealing ring, the outer ring of the sealing ring overlaps the inner wall of the oil pipeline 3, and the surface of the sealing ring is symmetrically fixedly connected with a one-way valve pipe. It should be noted that: the lower part of the inner wall of the oil pipeline 3 is fixedly connected with a sealing ring that matches the outer wall of the regulating tube 601.

[0033] An oil drain groove is provided on the side wall of the upper part of the regulating tube 601, and a filter plate is fixedly connected to the inner wall of the oil drain groove. It should be noted that the one-way valve tube is composed of a vertical tube and a one-way valve. When the regulating tube 601 moves downward, the sealing mechanism 603 on the upper part of the regulating tube 601 is reset and closed. At this time, a sealed chamber is formed between the upper part of the regulating tube 601 and the regulating ring 602. During the relative movement between the upper part of the regulating tube 601 and the regulating ring 602, the collected waste chips and oil are compressed. Under the action of pressure, the oil enters the one-way valve tube from the filter plate position, so that the excess oil flows back into the oil delivery pipe 3.

[0034] In this embodiment, Figures 1 to 9 As shown, the end of the L-shaped oil discharge pipe 7 near the oil delivery pipe 3 is fixedly connected with a filter screen, the surface of the upper gear ring 6038 is vertically slidably connected with a slide bar, the lower part of the slide bar and the bottom of the gear ring 6038 are movably connected with a return spring, and the top of the slide bar penetrates the gear ring 6038 and is fixedly connected with a brush plate that matches the filter screen. It should be noted that when the regulating pipe 601 rises with the sealing cone ring 6032 at the top, the sealing cone ring 6032 presses against the bottom of the slide bar, so that the slide bar rises with the brush plate, and the filter screen at the position of the L-shaped oil discharge pipe 7 is cleaned to avoid clogging of the filter screen.

[0035] In this embodiment, Figures 1 to 9 As shown, the lower part of the right side of the oil feeder housing 1 is provided with a door matched with the collecting bin 4. It should be noted that a filtering partition is provided on the right side of the inner wall of the collecting bin 4 to facilitate filtering and recovering excess oil.

[0036] The use method and advantages of the present invention: The oil supply device for a CNC machine tool oil pump has the following working process: like Figures 1 to 9 As shown, when in use, the circulating oil pump 2 transports the oil from the oil delivery pipe 3 to the L-shaped oil discharge pipe 7. At this time, the iron filings filtered out of the oil are deposited between the lower part of the oil delivery pipe 3 and the sealing plate 6033 at the top of the regulating pipe 601; When the electric telescopic rod 507, the connecting block 508 and the friction sleeve 501 are raised, the friction sleeve 501 and the adjusting column 502 are raised synchronously under the action of friction resistance. When the adjusting column 502 rises to the limit position, as the friction sleeve 501 continues to move upward, the spiral groove 503 on the adjusting column 502 and the adjusting pin 504 inside the friction sleeve 501 cooperate and slide, so that the adjusting column 502 and the Y-shaped bracket tube 509 rotate; As the Y-shaped bracket tube 509 moves upward with the adjusting column 502, the Y-shaped bracket tube 509 brings the adjusting tube 601 up inside the oil pipeline 3. When the adjusting tube 601 rises to the limit position, the tooth block 6037 at the top of the sealing cone ring 6032 is engaged with the tooth ring 6038 inside the oil pipeline 3. When the Y-shaped bracket tube 509 brings the adjusting tube 601 to rotate, the adjusting tube 601 brings the hinged pull rod 6035 to move, so that one end of the pull rod 6035 pulls the hinged sealing plate 6033 to deflect at the bottom of the sealing cone ring 6032. At this time, the five sealing plates 6033 deflect synchronously and release the sealing state, so that the iron filings deposited at the bottom of the oil pipeline 3 fall into the inside of the adjusting tube 601. Since the sealing mechanism 603 inside the adjusting tube 601 is opposite to the sealing mechanism 603 at the top of the adjusting tube 601, the five sealing plates 6033 at the top of the adjusting ring 602 are in a sealed state. Then the electric telescopic rod 507 is started to move downward and reset. At this time, the friction sleeve 501 moves downward with the adjusting column 502. When the adjusting column 502 moves downward to the limit position, as the friction sleeve 501 continues to move downward, the adjusting pin 504 inside the friction sleeve 501 cooperates and slides with the spiral groove 503 on the surface of the adjusting column 502, so that the adjusting column 502 rotates in the opposite direction. In this process, when the adjusting tube 601 moves downward with the collected iron filings, the tooth block 6037 on the upper part of the adjusting tube 601 is disengaged from the corresponding tooth ring 6038. Under the action of the reset spring 6036, the sealing cone ring 6032 on the upper part of the adjusting tube 601 is reset and reversed, so that the sealing plate 6033 on the upper part of the adjusting tube 601 is reset and the upper position of the adjusting tube 601 is sealed again. When the adjusting tube 601 rotates after being moved downward, the toothed ring 6038 inside the adjusting tube 601 is engaged with the toothed block 6037 on the top of the adjusting ring 602 to limit the position. At this time, the adjusting tube 601 rotates with the toothed ring 6038, the toothed block 6037 and the sealing cone ring 6032 inside. Since the adjusting ring 602 cannot rotate, the pull rod 6035 at the bottom of the sealing cone ring 6032 pulls the sealing plate 6033 to rotate. At this time, the sealing plate 6033 inside the adjusting tube 601 is deflected and opened, and the iron filings collected inside the adjusting tube 601 are automatically discharged into the collecting bin 4. In this way, as the electric telescopic rod 507 reciprocates and extends in stages, the iron filings filtered out from the inside of the oil pipeline 3 are automatically collected.
