Description

Technical Field

[0001] This invention relates to the field of parts processing technology, specifically to a CNC machining equipment and a CNC high-gloss machining process for precision parts. Background Technology

[0002] CNC machining equipment is an automated machining equipment that uses computer programs to control the movement trajectory and operation sequence of machine tools. According to the machining process, it can be roughly divided into: metal cutting CNC lathes, special machining machine tools, sheet metal processing machine tools, etc. Among them, precision parts such as camera decorative parts and button structural parts often need to be further polished by CNC machine tools after production.

[0003] Most high-gloss machining tools currently available achieve high-gloss processing on precision parts through grinding. However, most existing high-gloss machining mechanisms do not have the ability to clean the processed parts. Because the machine tool needs to grind the surface of the parts and spray grinding fluid during high-gloss processing, grinding fluid and grinding debris often remain on the surface of the parts after high-gloss processing. This means that manual cleaning is still required after processing. Although manual cleaning is convenient, its efficiency is relatively limited when batch processing is carried out. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a CNC machining equipment and a CNC high-gloss machining process for precision parts in structural components such as camera decorative parts and buttons, thus solving the aforementioned problems.

When the flipped processing table moves to contact the pushing mechanism, the pushing mechanism can drive the base to move toward the processing table. When the base moves, the flipping component can drive the nozzle to flip to the opposite side of the processing table and mold part.

A connecting spring is fixedly connected to one side of the connecting block, and the end of the connecting spring away from the connecting block is fixedly connected to the inner side of the machine tool. The connecting spring is distributed on the outer side of the base rod.

[0011] Preferably, the driving component includes a reciprocating lead screw, a long rack, and a limiting rod. A double-layered corner bracket is rotatably connected to the outer side of the reciprocating lead screw, and a mounting shaft is rotatably connected to the inner side of the double-layered corner bracket. A speed-changing gear is fixedly connected to the mounting shaft, and a pinion meshes with the outer side of the speed-changing gear. The pinion is fixedly connected to the reciprocating lead screw. A single-layered corner bracket is fixedly connected to the outer side of the limiting rod. The single-layered corner bracket is fixed to the triangular part of the base away from the double-layered corner bracket.

[0014] Preferably, the flipping component further includes a round-headed slot, and a plurality of round-headed rubber rods are distributed circumferentially on the flipping gear. When the flipping gear rotates, the round-headed rubber rods can be inserted into the round-headed slot.

[0015] A CNC high-gloss machining process for precision parts, using the aforementioned CNC machining equipment.

[0016] Compared with the prior art, the present invention provides a CNC machining equipment and a CNC high-gloss machining process for precision parts, which has the following beneficial effects: 1. In this invention, during processing, the part mold to be processed is mounted on a processing table, and then processed by a machine tool. After processing, a moving mechanism drives the base, processing table, and part mold to move towards the discharge port. When the processing table approaches the discharge port, an electric push rod drives the processing table and part mold to flip until the processing table is tilted. Then, the moving mechanism drives the tilted processing table and part mold to continue moving. When the processing table moves to contact the pushing mechanism, the pushing mechanism drives the base and nozzle to move towards the processing table and part mold. When the base moves, the flipping mechanism... The rotating nozzle flips to the opposite side of the part mold, and then blows air to clean the part mold and the machining table, thereby removing the grinding fluid and grinding debris remaining on the part mold. The cleaned grinding fluid and debris fall into the discharge port after being cleaned by the nozzle, and are then discharged through the discharge port. This achieves the effect of cleaning the part mold after machining. Furthermore, because the part mold is tilted when the nozzle is cleaning the part mold, the cleaned grinding fluid and debris can fall off the part mold more quickly, thereby improving the cleaning effect of the part mold.

[0017] 2. In the initial state, one of the round-headed rubber rods on the flipping gear is inserted into the round-headed slot. When the pushing mechanism drives the base to move towards the processing table, the flipping component drives the nozzle to flip. At this time, the round-headed rubber rod that was originally inserted into the round-headed slot moves out of the round-headed slot as the flipping gear rotates. After the nozzle rotates to the opposite side of the processing table, the other round-headed rubber rod on the flipping gear is inserted into the round-headed slot, thus completing the positioning of the nozzle. As the base continues to move, the driving component drives the nozzle to move up and down reciprocally. At this time, the nozzle can perform comprehensive air blowing cleaning on the part mold, thereby further improving the cleaning effect on the part mold. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a CNC machining equipment and a CNC high-gloss machining process for precision parts.

[0022] Example 1: Please refer to Figures 1-9 A CNC machining equipment includes a machine tool 1, a moving mechanism 2 and several machining axes on the machine tool 1, a base 3 on the moving mechanism 2, an electric push rod 4 on the base 3, and a machining table 5 on the base 3. During machining, the moving mechanism 2 can drive the base 3 to move laterally and longitudinally, and the electric push rod 4 is used to drive the machining table 5 to rotate. A base 6 is slidably mounted on the machine tool 1. A pushing mechanism 8 and a cleaning mechanism 7 are mounted on the base 6. The pushing mechanism 8 is used to drive the base 6 to move. The cleaning mechanism 7 includes a nozzle 71, a drive component 72, a tilting component 73, and a discharge port 74. The nozzle 71 is used to clean the part mold, the drive component 72 is used to drive the nozzle 71 to move up and down reciprocally, the tilting component 73 is used to drive the nozzle 71 to tilt, and the discharge port 74 is used to discharge the debris and grinding fluid after cleaning. During cleaning, the moving mechanism 2 drives the base 3 and the processing table 5 to move toward the discharge port 74. When the processing table 5 moves to a position close to the discharge port 74, the electric push rod 4 drives the processing table 5 and the part mold to flip until the processing table 5 and the base 3 form an acute angle. When the flipped processing table 5 moves to contact the pushing mechanism 8, the pushing mechanism 8 can drive the base 6 to move toward the processing table 5. When the base 6 moves, the flipping component 73 can drive the nozzle 71 to flip to the opposite side of the processing table 5 and the mold part. Subsequently, the driving component 72 can drive the nozzle 71 to move up and down reciprocally.

[0023] In use, the part mold to be processed is installed on the processing table 5. Then, the part mold is processed by the machine tool 1 and the processing axis. After processing, the base 3, processing table 5, and part mold are moved towards the discharge port 74 by the moving mechanism 2. When the processing table 5 approaches the discharge port 74, the processing table 5 and part mold are flipped by the electric push rod 4 until the processing table 5 and part mold are tilted. Then, the tilted processing table 5 and part mold are moved further by the moving mechanism 2. When the processing table 5 moves to contact the pushing mechanism 8, the pushing mechanism 8 drives the base 6 and nozzle 71 to move towards the processing table 5 and part mold. When the base 6 moves, the flipping component 73 drives the nozzle 71 to flip to the opposite side of the part mold. At this time, the nozzle 71 rotates to... The part mold is cleaned by air blowing. After the nozzle 71 is turned on, the push mechanism 8 continues to drive the base 6 to move. At this time, the drive component 72 can drive the nozzle 71 to move up and down. The nozzle 71 can clean the part mold from top to bottom by air blowing, thereby removing the grinding fluid and grinding debris remaining on the part mold. The cleaned grinding fluid and debris fall into the discharge port 74 after being cleaned by the nozzle 71, and then are discharged through the discharge port 74. This achieves the effect of thoroughly cleaning the processed part mold. Furthermore, when the nozzle 71 cleans the part mold, the part mold is tilted at this time, which allows the cleaned grinding fluid and debris to fall off the part mold more quickly, thereby improving the cleaning effect of the part mold.

[0024] It should be noted that the moving mechanism 2 is driven by a ball screw in the prior art, which is common knowledge to those skilled in the art, and will not be described in detail again. Furthermore, the size of the part mold is smaller than the size of the processing table 5.

[0025] Example 2: See Figures 1-9Unlike the first embodiment described above, the electric push rod 4 is fixedly connected to one side of the base platform 3. The output shaft of the electric push rod 4 passes through the base platform 3 and is fixedly connected to a long slide table 41. Slider 42 is symmetrically arranged at the bottom of the long slide table 41. Slide rail 43 is slidably connected to the inner side of the slider 42. The slide rail 43 is distributed on the inner side of the base platform 3. Fixed rod 44 is symmetrically arranged on the inner side of the long slide table 41. Connecting rod 45 is hinged to the outer side of the fixed rod 44. Moving rod 46 is hinged to the end of the connecting rod 45 away from the fixed rod 44. Fixed platform 47 is fixedly connected to the outer side of the moving rod 46. Fixed platform 47 is fixedly connected to the bottom surface of the processing table 5. Positioning platform 48 is fixedly connected to the end of the processing table 5 away from the fixed platform 47. Rotating shaft 49 is fixedly connected to the inner side of the positioning platform 48. The two ends of the rotating shaft 49 are rotatably connected to the base platform 3 through bearing seats. In the initial state, the output shaft of the electric push rod 4 is extended. During use, the electric push rod 4 drives the long slide table 41 to move along the slide rail 43. The movement of the long slide table 41 drives the fixed rod 44 to move. The movement of the fixed rod 44 drives the connecting rod 45 to rotate around the fixed rod 44. The rotation of the connecting rod 45 drives the moving rod 46 and the fixed platform 47 to move upward. The upward movement of the fixed platform 47 drives the processing table 5 to rotate around the rotating shaft 49. At this time, the processing table 5 is driven into an inclined state. Since the part mold is installed on the processing table 5, the flipping of the processing table 5 also drives the part mold to flip and tilt, which facilitates the subsequent cleaning of the part mold.

[0026] Example 3, see Figures 1-9 Unlike the second embodiment described above, the pushing mechanism 8 includes a hydraulic pipe 81, which is fixedly connected to the inside of the machine tool 1. The two ends of the inner side of the hydraulic pipe 81 are slidably connected to an extension rod 82 and a retracting rod 83, respectively. A pressure plate 84 is fixedly connected to the upper part of the extension rod 82, and a return spring 85 is fixedly connected to the pressure plate 84. The end of the return spring 85 away from the pressure plate 84 is fixedly connected to the end of the hydraulic pipe 81 near the extension rod 82. The outer end of the retracting rod 83 is fixedly connected to the base 6. The pushing mechanism 8 also includes a bottom rod 86, which is symmetrically fixedly connected to the inside of the machine tool 1. A connecting block 87 is slidably connected to the bottom of the base 6. A connecting spring 88 is fixedly connected to one side of the connecting block 87. The end of the connecting spring 88 away from the connecting block 87 is fixedly connected to the inside of the machine tool 1, and the connecting spring 88 is distributed on the outside of the bottom rod 86. In use, the processing table 5 and the part mold are first driven to flip by the electric push rod 4. Then, the processing table 5 is driven to move by the moving mechanism 2. After the processing table 5 moves, it contacts the pressure plate 84 at one end of the hydraulic pipe 81 and drives the pressure plate 84 to move. The pressure plate 84 moves and squeezes the return spring 85 and drives the extension rod 82 to move into the hydraulic pipe 81. The extension rod 82 retracts and squeezes the hydraulic oil in the hydraulic pipe 81. At this time, under the transmission of hydraulic oil, the retracting rod 83 is gradually extended out of the hydraulic pipe 81. The movement of the retracting rod 83 drives the base 6 and the connecting block 87 to move along the base rod 86. The movement of the connecting block 87 stretches the connecting spring 88. The movement of the base 6 drives the nozzle 71 to move towards the processing table 5, thereby facilitating the subsequent cleaning of the part mold by the nozzle 71.

[0027] Example 4, see Figures 1-9 Unlike Embodiment 3 described above, the driving component 72 includes a reciprocating lead screw 721, a long rack 726, and a limiting rod 727. A double-layered corner frame 722 is rotatably connected to the outer side of the reciprocating lead screw 721, and a mounting shaft 723 is rotatably connected to the inner side of the double-layered corner frame 722. A speed-changing gear 724 is fixedly connected to the mounting shaft 723, and a pinion 725 meshes with the outer side of the speed-changing gear 724. The pinion 725 is fixedly connected to the reciprocating lead screw 721. A single-layered corner frame 728 is fixedly connected to the outer side of the limiting rod 727, and the single-layered corner frame 728 is fixed to the base 6. At the triangular position away from the double-layer corner 722, the end of the reciprocating screw 721 away from the double-layer corner 722 is rotatably connected to the single-layer corner 728. When the speed-changing gear 724 moves, it can mesh with the long rack 726. The nozzle 71 is provided with several arrayed oblique nozzles 711. The nozzle 71 is also provided with a connecting pipe, which is connected to an air compressor. The two ends of the nozzle 71 are rotatably connected to short slides 712. The two ends of the short slides 712 are respectively set on the reciprocating screw 721 and the limit rod 727. When the reciprocating screw 721 rotates, it can drive the short slides 712 to move. In the initial state, the gear 724 is separated from the long rack 726. When the base 6 moves, the flipping component 73 first drives the nozzle 71 to flip. Then, as the base 6 moves, the gear 724 on the double-layer corner platform 722 meshes with the long rack 726. When the base 6 moves, the long rack 726 drives the gear 724 to rotate. The rotation of the gear 724 drives the pinion 725 to rotate. The rotation of the pinion 725 drives the reciprocating screw 721 to rotate. The rotation of the reciprocating screw 721 drives the short slide 712, the nozzle 71, and the angled nozzle 711 to move up and down along the limit rod 727. The movement of the nozzle 71 realizes the moving cleaning of the part mold, thereby improving the cleaning effect of the part mold.

[0028] It should be noted that the double-layer corner unit 722 is equipped with an elastic plate, which can lock the gear 724 when the gear 724 is not rotating.

[0029] Example 5, see Figures 1-9 Unlike Embodiment 4 above, the flipping component 73 includes a short rack 731, which is fixedly connected to the inner side of the machine tool 1. A flipping gear 732 meshes with the inner side of the short rack 731. A driving wheel 733 is coaxially fixedly connected to the flipping gear 732. A driven wheel 734 is drivenly connected to the inner side of the driving wheel 733. The driven wheel 734 is fixedly connected to the nozzle 71. The flipping gear 732 is rotatably connected to the single-layer corner platform 728 through a transmission shaft. The flipping component 73 also includes a round-headed slot 736. Several round-headed rubber rods 735 are distributed circumferentially on the flipping gear 732. When the flipping gear 732 rotates, the round-headed rubber rods 735 can be inserted into the round-headed slot 736. In the initial state, one of the round-headed rubber rods 735 on the flip gear 732 is inserted into the round-headed slot 736. When the pushing mechanism 8 drives the base 6 to move towards the processing table 5, the flip gear 732 moves along the short rack 731. At this time, the short rack 731 drives the flip gear 732 to rotate. The rotation of the flip gear 732 drives the driving wheel 733 to rotate. The rotation of the driving wheel 733 drives the driven wheel 734 to rotate. The rotation of the driven wheel 734 drives the nozzle 71 to rotate. During rotation, the round-headed rubber rod 735, which was originally inserted into the round-headed slot 736, moves out of the round-headed slot 736. After the nozzle 71 rotates to the opposite side of the processing table 5, another round-headed rubber rod 735 on the flip gear 732 is inserted into the round-headed slot 736, thus completing the positioning of the nozzle 71. After the nozzle 71 flips, it begins to operate, thereby cleaning the part mold. After the base 6 is reset, the flip gear 732 drives the nozzle 71 to reset, at which point the nozzle 71 stops operating.

[0030] It should be noted that a sensor is installed on the nozzle 71, which is connected to the PLC controller on the machine tool 1. When the nozzle 71 rotates, it can detect the rotation and feed the information back to the PLC controller. At this time, the PLC controller starts and stops the air compressor connected to the nozzle 71.
