Description

Technical Field

[0001] The invention relates to the technical field of metal cutting machine tools, in particular to a metal cutting machine tool capable of liquid-chip separation. Background Art

[0002] A metal cutting machine tool is a type of mechanical equipment that uses the cutting principle to remove excess material from a metal blank through relative motion between the tool and the workpiece to produce metal parts with specific shapes, dimensional accuracy and surface quality. It is a key basic equipment in the machinery manufacturing industry.

[0003] There are various cutting methods for spherical workpieces. During turning, a CNC lathe program controls the tool, performing rough turning followed by finish turning, with corresponding cutting methods for the inner and outer spherical surfaces. Milling, using multi-axis milling machines, can process complex, high-precision spherical workpieces from various angles. Grinding, using a grinder to drive the abrasive material, is a micro-grinding method for spherical workpieces requiring high precision and surface quality. Laser cutting uses a laser beam to rapidly melt or vaporize the material, making it suitable for difficult-to-cut materials, offering high cutting speeds and precision.

[0004] Chucks are widely used in various fixing methods. Three-jaw chucks are used for regular, small blanks, while four-jaw chucks are suitable for eccentric or irregular blanks. A "one-clamp, one-lift" system, combined with a center and fixture, is suitable for longer and heavier workpieces. A "double-center" system with a dial is used for slender shafts. Furthermore, specialized fixtures with tapered slots or curved clamping blocks can precisely locate the center of spherical workpieces while preventing pinching injuries.

[0005] However, due to the curved surface characteristics of the spherical workpiece, the three-jaw chuck may not be able to clamp the workpiece evenly and stably, resulting in a decrease in machining accuracy; therefore, it does not meet the existing needs. In this regard, we propose a metal cutting machine tool with liquid-chip separation. Summary of the Invention

[0019] The present invention has the following beneficial effects: 1. The metal cutting machine tool with liquid-chip separation is designed with an arc-shaped extension device and a side pressing and fixing device, so that the spherical workpiece is subjected to downward forces at four angles. This downward-slanting design can effectively ensure that the spherical workpiece will not slide upward during the processing. The four-angle design ensures that the spherical workpiece will not slide left and right, front and back during the processing, thereby ensuring the stability of the processing process. Compared with the three-jaw chuck and four-jaw chuck in the prior art, the design of this scheme has designed a special base for the spherical workpiece, and changed the direction of the force of the three-jaw chuck and the four-jaw chuck to squeeze and fix the spherical workpiece. Through this improvement, the stable clamping of the spherical workpiece can be further guaranteed, and the stability of the spherical workpiece during the processing can be further guaranteed.

[0020] 2. The metal cutting machine tool capable of liquid-chip separation has a stage connection device designed to automatically adjust the order of movement of the arc extension device and the side pressing and fixing device. In order to ensure that the pressing slider can normally extrude the spherical workpiece, it is necessary to ensure that the sliding of the pressing slider is after the arc extension slider, and it is necessary to ensure that the sliding is carried out after the arc extension slider is completely stopped. The stage connection device is composed of a first elastic switch through a No. 1 annular base, a No. 1 top plate, and a No. 1 spring. The design of this elastic switch ensures that when the arc extension slider has not completely slid to a stop, under the action of the No. 1 spring, the No. 1 top plate is always closed with the No. 1 annular base to ensure sealing. When the arc extension slider cannot slide, the No. 1 top plate is pushed open by the hydraulic oil through the push of the electric push rod and the hydraulic transmission, and the hydraulic oil is transported to the telescopic shell, thereby driving the telescopic inner rod and the pressing slider fixedly connected thereto to slide outward and exert pressure on the spherical workpiece, ensuring the normal progress of the fixing process.

[0021] 3. The metal cutting machine tool with liquid-chip separation, the vacuum adsorption device is designed to further ensure the fixing effect of the spherical workpiece. Through the design of the vacuum adsorption device, vacuum adsorption can be used to ensure the fixing effect between the spherical workpiece and the pressing slider. When sliding occurs between the telescopic outer shell and the telescopic inner rod, the adsorption slide plate in the pressing slider is fixedly connected to the telescopic outer shell, and the telescopic inner rod is fixedly connected to the pressing slider. When the pressing slider slides outward, the adsorption slide plate located in the pressing slider slides backward, so that the front half space of the pressing slider has an air suction effect. When the surface of the pressing slider conflicts with the outer surface of the spherical workpiece, and under the suction of the adsorption slide plate, the fixing effect between the pressing slider and the spherical workpiece can be further improved, and the stability of the spherical workpiece during processing is further guaranteed.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1: This example aims to solve the problem that due to the curved surface characteristics of the spherical workpiece, the three-jaw chuck may not be able to clamp the workpiece evenly and stably, resulting in a decrease in machining accuracy. Figures 1 to 11 A metal cutting machine tool with liquid-chip separation includes a machine tool body 1, which includes a support 11. A processing device 12 is installed on the top of the support 11, and a mounting base 13 is installed on the bottom of the support 11. The top of the mounting base 13 is fixedly connected to a hemispherical mounting shell 14, and a spherical workpiece 15 is placed in the hemispherical mounting shell 14. The hemispherical mounting shell 14 is provided with an arc-shaped extension device 2 and a side pressing and fixing device 3 for fixing the spherical workpiece 15.

[0036] The processing equipment 12 is used to perform cutting processing on the spherical workpiece 15. The mounting base 13 and the hemispherical mounting shell 14 provide support and installation space for the spherical workpiece 15. The operator places the spherical workpiece 15 into the hemispherical mounting shell 14 and fixes the spherical workpiece 15 in the hemispherical mounting shell 14 through the operation of the arc-shaped extension device 2 and the side pressing and fixing device 3. Due to the hemispherical design of the hemispherical mounting shell 14, it can effectively ensure that the spherical workpiece 15 will not slip during the processing process.

[0037] The arc-shaped extension device 2 includes an arc-shaped extension slot 21 provided in the hemispherical mounting housing 14 , an arc-shaped extension slider 22 is slidably connected in the arc-shaped extension slot 21 , and a side pressing and fixing device 3 is provided in the arc-shaped extension slider 22 .

[0038] A hydraulic drive groove 24 is provided in the mounting base 13, and an electric push rod 25 is installed in the hydraulic drive groove 24. The output end of the electric push rod 25 is fixedly connected to a hydraulic drive plate 26, and the hydraulic drive plate 26 is slidably connected in the hydraulic drive groove 24. The top of the hydraulic drive groove 24 is connected with a hydraulic connecting groove 23, and the other end of the hydraulic connecting groove 23 is connected with the arc-shaped extending chute 21. Hydraulic oil is filled in the bottom of the arc-shaped extending chute 21, the hydraulic connecting groove 23 and the top of the hydraulic drive groove 24. The hydraulic connecting groove 24 is provided in the hemispherical mounting shell 14.

[0039] In order to ensure the correct extrusion of the spherical workpiece 15, it is necessary to extend the arc-shaped extending slider 22 and move the arc-shaped extending slider 22 equipped with the pressing slider 33 to the upper half of the spherical workpiece 15. Since there are four groups of arc-shaped extending devices 2 arranged on the circumference, the four groups of arc-shaped extending devices 2 arranged in a circular array can drive the four pressing sliders 33 to extrude the spherical workpiece 15. At the same time, this orientation can effectively ensure the balance of torque, thereby ensuring that the spherical workpiece 15 can be subjected to uniform force, so that the spherical workpiece 15 can be firmly fixed in the hemispherical mounting shell 14, ensuring the stability of the processing equipment 12 when processing the spherical workpiece 15, and improving the processing accuracy.

[0040] After the spherical workpiece 15 is placed in the hemispherical mounting shell 14, the electric push rod 25 drives the hydraulic drive plate 26 to slide upward. Since the arc-shaped extension groove 21, the hydraulic connecting groove 23 and the hydraulic drive groove 24 are filled with hydraulic oil, the sliding of the hydraulic drive plate 26 and the connection of the hydraulic passage drive the arc-shaped extension slider 22 to slide in the arc-shaped extension groove 21. Due to the arc-shaped design of the arc-shaped extension slider 22 and the arc-shaped extension groove 21, the arc-shaped extension slider 22 can move along the curvature of the hemispherical mounting shell 14 after being extended, thereby effectively preventing the spherical workpiece 15 from sliding out of the hemispherical mounting shell 14.

[0041] The side pressing and fixing device 3 includes a pressing groove 32 opened in the arc-shaped extending slider 22, and a pressing slider 33 is slidably connected in the pressing groove 32. Under the drive of the arc-shaped extending device 2, the pressing slider 33 extends out of the pressing groove 32 and applies pressure to the spherical workpiece 15 to fix the spherical workpiece 15.

[0042] The side pressing and fixing device 3 includes a side movable groove 31 provided in the arc-shaped extending slider 22, and a telescopic inner rod 34 is fixedly connected to one side of the pressing slider 33. The other end of the telescopic inner rod 34 is slidably connected in the telescopic outer shell 35. A telescopic spring 36 is connected between the telescopic inner rod 34 and the telescopic outer shell 35. The telescopic inner rod 34 and the telescopic outer shell 35 are arranged in the side movable groove 31.

[0043] A bottom fixing device 4 is provided at the bottom of the arc-shaped extending slider 22, and the bottom fixing device 4 includes a bottom push groove 41 opened at the bottom of the hemispherical mounting shell 14, a bottom push block 42 is slidably connected in the bottom push groove 41, and a bottom spring 43 is fixedly connected to the bottom of the bottom push block 42, a stop block 44 is installed in the bottom push groove 41, and the bottom of the bottom spring 43 is installed in the stop block 44.

[0044] Under the control of the stage connecting device 5, after the arc-shaped extending slider 22 is fully extended, it drives the pressing slider 33 in the arc-shaped extending slider 22 to slide outward, and then the pressing slider 33 squeezes the spherical workpiece 15. Since there are also four groups of pressing sliders 33, the spherical workpiece 15 is subjected to forces in four directions, and since the center of the hemispherical mounting shell 14 is the same as that of the spherical workpiece 15, the direction of the force exerted on the spherical workpiece 15 is pointing to the center of the sphere, thereby ensuring that the spherical workpiece 15 can be subjected to a downward extrusion force. At the same time, the bottom fixing device 4 provided at the bottom of the hemispherical mounting shell 14 applies an upward force to the spherical workpiece 15. Through the interaction of these five forces, the spherical workpiece 15 can be fixed inside the hemispherical mounting shell 14, thereby ensuring the stability of the spherical workpiece 15 during the processing process.

[0045] Compared with the three-jaw chuck and four-jaw chuck in the prior art, the design of this solution designs a special base for the spherical workpiece 15, and changes the direction of the force used by the three-jaw chuck and four-jaw chuck to squeeze and fix the spherical workpiece 15. Through this improvement, the stability of the clamping of the spherical workpiece can be further guaranteed, and the stability of the spherical workpiece 15 during the processing process can be further guaranteed.

[0046] Example 2: This example is intended to solve the problem of the pressing slider 33 and the arc-shaped extending slider 22 extending in sequence. This example is an explanation based on Example 1. For details, please refer to Figures 1 to 11A stage communication device 5 is provided in the arc-shaped extending slider 22. The stage communication device 5 includes a stage communication groove 51 opened at the bottom of the arc-shaped extending slider 22. The top of the stage communication groove 51 is connected to a stage communication hose 52. The other end of the stage communication hose 52 is connected to the interior of the telescopic shell 35.

[0047] A No. 1 annular base 53 is fixedly connected to the stage connecting groove 51, and a No. 1 top plate 54 is provided on the top of the No. 1 annular base 53. The No. 1 top plate 54 and the No. 1 annular base 53 are connected by a No. 1 spring 55. A No. 2 cylinder 56 is fixedly connected to one side of the No. 1 top plate 54, and a No. 2 top plate 57 is provided at the other end of the No. 2 cylinder 56. The No. 2 top plate 57 and the No. 2 cylinder 56 are connected by a No. 2 spring 58.

[0048] The stage communication device 5 is designed to automatically adjust the order of movement of the arc-shaped extension device 2 and the side pressing and fixing device 3. In order to ensure that the pressing slider 33 can normally squeeze the spherical workpiece 15, it is necessary to ensure that the sliding of the pressing slider 33 is after the arc-shaped extension slider 22, and it is necessary to ensure that it is carried out after the arc-shaped extension slider 22 completely stops. The stage communication device 5 is composed of a first elastic switch through a No. 1 annular base 53, a No. 1 top plate 54, and a No. 1 spring 55. The design of this elastic switch ensures that when the arc-shaped extension slider 22 has not completely slid to a stop, under the action of the No. 1 spring 55, the No. 1 top plate 54 is always closed with the No. 1 annular base 53 to ensure sealing. When the arc-shaped extension slider 22 cannot slide, the No. 1 top plate 54 is pushed open by the electric push rod 25 and the hydraulic transmission, and the hydraulic oil is transported to the telescopic shell 35, thereby driving the telescopic inner rod 34 and the pressing slider 33 fixed thereto to slide outward and apply pressure to the spherical workpiece 15, ensuring the normal progress of the fixing process.

[0049] Due to this one-way design, the pressing slider 33 cannot be reset. Therefore, the second cylinder 56, the second top plate 57, and the second spring 58 are designed. When the hydraulic drive plate 26 is driven to slide upward, the second top plate 57 always closes the second cylinder 56 under the action of the hydraulic oil. When it needs to be reset, the hydraulic drive plate 26 slides downward. At this time, the arc extends out of the chute 21 to form a negative pressure. At the same time, since the first top plate 54 is not driven by the hydraulic oil, the first annular base 53 is closed again under the action of the first spring 55. At this time, due to the hydraulic drive The negative pressure generated by the sliding of the movable plate 26 in the arc-shaped extending groove 21 will drive the No. 2 top plate 57 and the No. 2 cylinder 56 to open, and then the liquid in the telescopic shell 35 will be extracted, driving the pressing slider 33 to reset. In this process, since the pressing slider 33 is located on the outside of the arc-shaped extending slider 22, the arc-shaped extending slider 22 is stuck by the pressing slider 33 and cannot be reset. Through this design, the order of movement of the arc-shaped extending device 2 and the side pressing and fixing device 3 can be automatically adjusted, thereby ensuring the normal fixation of the spherical workpiece 15.

[0050] Example 3: This example is intended to further improve the fixing effect of the spherical workpiece 15. This example is an explanation based on Example 2. For details, please refer to Figures 1 to 11 A vacuum adsorption device 6 is provided in the pressing slider 33. The vacuum adsorption device 6 includes an adsorption groove 61 opened in the pressing slider 33. An adsorption hole 62 is opened on the side wall of the pressing slider 33. An adsorption slide 63 is slidably connected in the adsorption groove 61. One side of the adsorption slide 63 is fixedly connected to an adsorption driving rod 64.

[0051] The other end of the adsorption drive rod 64 is fixedly connected to the telescopic outer shell 35 , and the adsorption drive rod 64 is slidably connected to the adsorption drive chute 65 , and the adsorption drive chute 65 is provided in the telescopic inner rod 34 .

[0052] The design of the vacuum adsorption device 6 is used to further ensure the fixing effect of the spherical workpiece 15. Through the design of the vacuum adsorption device 6, vacuum adsorption can be used to ensure the fixing effect between the spherical workpiece 15 and the pressing slider 33. When sliding occurs between the telescopic outer shell 35 and the telescopic inner rod 34, the adsorption slide 63 in the pressing slider 33 is fixedly connected to the telescopic outer shell 35, and the telescopic inner rod 34 is fixedly connected to the pressing slider 33. When the pressing slider 33 slides outward, the adsorption slide 63 located in the pressing slider 33 slides backward, so that the front half space of the pressing slider 33 has an air suction effect. When the surface of the pressing slider 33 conflicts with the outer surface of the spherical workpiece 15, and under the suction of the adsorption slide 63, the fixing effect between the pressing slider 33 and the spherical workpiece 15 can be further improved, further ensuring the stability of the spherical workpiece 15 during processing.

[0053] A spherical cleaning device 7 is provided in the pressing slider 33. The spherical cleaning device 7 includes a mounting groove 71 opened on the surface of the pressing slider 33. A rubber cleaning scraper 72 is installed in the mounting groove 71. The side wall of the rubber cleaning scraper 72 is fixedly connected to a track slider 74. The track slider 74 is slidably connected in the track groove 73. The track groove 73 is opened on the inner wall of the pressing slider 33.

[0054] A telescopic slot 75 is provided on one side of the rubber cleaning scraper 72, and a telescopic block 76 is slidably connected in the telescopic slot 75. A bellows 77 is fixedly connected to one side of the telescopic block 76, and the other end of the bellows 77 is connected to a drive hose 78, which is connected to the telescopic housing 35.

[0055] In order to further ensure the adsorption effect of the vacuum adsorption device 6, it is necessary to ensure that the outer surface of the spherical workpiece 15 is clean and smooth. The installation groove 71 is used to place the rubber cleaning scraper 72. The rubber cleaning scraper 72 is used to clean the outer surface of the spherical workpiece 15. The rubber material makes the rubber cleaning scraper 72 have greater ductility. While the hydraulic oil is filled in the telescopic shell 35, the hydraulic oil is synchronously filled into the bellows 77 through the connection of the driving hose 78. The hydraulic oil filled in the bellows 77 will drive the bellows 77 to continuously extend. Since the top of the bellows 77 is connected to the telescopic block 76, the telescopic block 76 and the rubber cleaning scraper 72 connected thereto are driven to slide upward synchronously. As the rubber cleaning scraper 72 slides upward, the slider 33 is pressed and the spherical workpiece 15 is also constantly approaching. In order to drive the rubber cleaning scraper 72 to clean the outer surface of the spherical workpiece 15, thereby ensuring a smooth connection between the spherical workpiece 15 and the adsorption hole 62, thereby ensuring the adsorption effect, the design of the track groove 73 allows the rubber cleaning scraper 72 to be completely recovered into the pressing slider 33 after cleaning is completed, and the protruding rubber cleaning scraper 72 will not cause the spherical workpiece 15 and the pressing slider 33 to be unable to be tightly connected, resulting in the inability to adsorb and fix. The telescopic design between the telescopic block 76 and the rubber cleaning scraper 72 is to adapt to the forward and backward movement of the rubber cleaning scraper 72. In order to ensure the verticality of the sliding of the telescopic block 76, a limit block can be set on one side of the telescopic block 76, and a limit groove can be set in the pressing slider 33 to ensure that the telescopic block 76 can only move up and down, further ensuring the stability of the sliding of the rubber cleaning scraper 72.
