Description

Technical Field

[0001] This invention belongs to the field of metal processing technology, specifically relating to a precision metal processing equipment and processing technology. Background Technology

[0002] In the machining of mechanical parts, many parts require deburring due to their precision requirements. This improves the precision of the metal parts, especially in bearing machining, where the outer ring of the bearing needs to be ground to remove burrs, thus improving the smoothness of bearing rotation and extending its service life. There are two main existing methods for deburring bearing outer rings: one is to hold the bearing outer ring and place it on a grinding mechanism to grind both the exterior and interior of the bearing; the other is to immerse the bearing in a polishing solution and add grinding needles for polishing and deburring.

[0003] However, in existing technologies, hand-held grinding for deburring is not only slow but also increases labor costs and is prone to safety accidents. Using polishing liquid for deburring requires polishing each bearing outer ring individually, which takes a long time and increases time costs. Furthermore, neither of the existing deburring equipment can achieve automated processing. In the existing technology, a Chinese patent document with publication number CN115365925A and publication date of November 22, 2022, proposes a method that uses an electric push rod to drive an electric chuck to descend into the interior of the bearing outer ring, activates the electric chuck to clamp the bearing outer ring, and activates a rotary cylinder to rotate the bearing outer ring. This then activates an upper reduction motor to move the bearing outer ring toward the grinding rod for grinding and polishing deburring. However, this method can only perform precision grinding on bearing outer rings of a fixed size and is not suitable for the tight processing of other bearing parts.

[0004] Therefore, we need a precision metal machining equipment and process to solve the problem that existing technologies can only perform precision grinding on bearing outer rings of fixed sizes and cannot be applied to the tight machining of other bearing parts. We need to be able to perform precision grinding according to the size fit of the bearing parts. Summary of the Invention

By changing the installation method, when the workpiece clamping seat clamps the metal workpiece from the inside, the sliding block is adjusted to allow the telescopic rod to perform precision grinding on the outer surface of the metal workpiece as the ring-shaped fixed machining table drives the rotary table to rotate. When the workpiece clamping seat clamps the metal workpiece from the outside, the sliding block is adjusted to allow the telescopic rod to move and perform precision grinding on the inner surface of the metal workpiece as the ring-shaped fixed machining table drives the rotary table to rotate. This solves the problem that existing technologies can only perform precision grinding on the outer ring of bearings of fixed dimensions and cannot be applied to the tight machining of other bearing parts. Precision grinding can be performed according to the dimensional fit of the bearing parts. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0033] Example 1

[0034] Please see Figures 1 to 8 This invention provides a technical solution: a metal precision machining equipment, including a metal precision machining equipment table 1, a fixed machining table mechanism 2 arranged at the rear of the metal precision machining equipment table 1, a drying mechanism 5 arranged at the bottom of the fixed machining table mechanism 2, an ultrasonic cleaning mechanism 4 arranged on the left side of the fixed machining table mechanism 2, a feeding mechanism 3 arranged at the rear of the fixed machining table mechanism 2, a rotating clamping table mechanism 6 arranged inside the fixed machining table mechanism 2, and a grinding mechanism 7 arranged above the fixed machining table mechanism 2; the fixed machining table mechanism 2 includes an annular fixed machining table 21 and a drive main motor 22; the rotating clamping table mechanism 6 includes a rotating table 61, and workpiece clamping seats 62 are symmetrically slidably mounted on the upper surface of the rotating table 61; the grinding mechanism 7 includes mounting brackets 71 fixedly mounted on both sides of the upper surface of the annular fixed machining table 21, a double-ended threaded rod 73 rotatably mounted above the mounting brackets 71, and a movable slider 74 symmetrically arranged in the middle of the double-ended threaded rod 73. A telescopic rod 75 is fixedly installed below the movable slider 74, and a precision grinding component 76 is fixedly installed at the output end of the telescopic rod 75; a ring-shaped fixed processing table 21 is fixedly installed below the partition on one side of the inner wall of the ring-shaped fixed processing table 21, and a drive motor 22 is rotatably installed above the partition on one side of the inner wall of the ring-shaped fixed processing table 21. The output shaft of the ring-shaped fixed processing table 21 is fixedly connected to the lower end of the rotating shaft of the drive motor 22, and a guide rail 24 is fixedly installed on the lower surface of the inner wall of the ring-shaped fixed processing table 21; a drive motor 72 is fixedly installed on one side of the upper end of the mounting frame 71, and the output shaft of the drive motor 72 is fixedly connected to one end of the double-threaded rod 73. A limiting rod adapted to the movable slider 74 is provided on one side of the double-threaded rod 73. The limiting rod is fixedly installed on the inner surface of the upper end of the mounting frame 71. The inner wall of the movable slider 74 is threadedly connected to the outer surface of the double-threaded rod 73. The telescopic rod 75 includes a mounting plate, a control component, a drive component, and a grinding tool component;

[0035] When the workpiece is placed above the rotating table 61, the workpiece clamping seat 62 can clamp the annular metal workpiece, such as the bearing, which needs to be precision machined. By changing the installation method, when the workpiece clamping seat 62 clamps the metal workpiece from the inside, the output shaft of the drive motor 72 is started, which drives the double-threaded rod 73 to rotate. This causes the moving slider 74 to move relative to the limit rod, adjusting the position of the telescopic rod 75. The telescopic rod 75 extends, bringing the precision grinding assembly 76 close to the outer surface of the metal workpiece. When the annular fixed machining table 21 drives the rotating table 61 to rotate, the outer surface of the metal workpiece is precision ground. Conversely, when precision machining and grinding the inner side of the metal workpiece, the telescopic rod 75 extends to the outer surface. The rod 75 first retracts, causing the precision grinding component 76 to move upward. Then, the drive motor 72 is restarted, rotating its output shaft to drive the double-threaded rod 73 to rotate. This causes the movable slider 74 to move relative to the limit rod again, adjusting the position of the telescopic rod 75. The telescopic rod 75 extends, bringing the precision grinding component 76 close to the inner surface of the metal workpiece. When the annular fixed processing table 21 drives the rotating table 61 to rotate, the inner surface of the metal workpiece is precision ground. This solves the problem that existing technologies can only perform precision grinding on the outer ring of bearings of fixed dimensions and cannot be applied to the tight processing of other bearing parts. Precision grinding can be performed according to the size fit of the bearing parts.

[0036] Example 2

[0037] Please see Figures 1 to 8 Based on Embodiment 1, in order to clamp the workpiece in coordination with the rotation of the rotating table 61, this embodiment proposes that the rotating table 61 is rotatably mounted in the middle of the annular fixed processing table 21, and a gear ring 611 that meshes with the main drive motor 22 is fixedly mounted on the middle of the outer side of the rotating table 61. A roller 612 that matches the guide rail 24 is provided on the lower bottom surface of the rotating table 61. An adjustment motor 63 is fixedly mounted in the middle of the lower bottom surface of the rotating table 61, and a main bevel gear 64 is rotatably mounted on the upper bottom surface of the rotating table 61. The bottom of the rotating shaft of the main bevel gear 64 is fixedly connected to the output shaft of the adjustment motor 63. Threaded rods 65 are symmetrically rotatably mounted on the inner sidewalls of the rotating table 61. A secondary bevel gear 66 that meshes with the main bevel gear 64 is fixedly mounted on one end of the threaded rod 65 near the main bevel gear 64. The outer surface of the secondary bevel gear 66 is threadedly connected to the inner bottom wall of the workpiece clamping seat 62.

[0038] The main motor 22 drives the drive gear 23 to rotate. Because the gear ring 611 meshes with the drive gear 23, the rotating table 61 will drive the workpiece to rotate, which facilitates the precision grinding assembly 76 to perform precision grinding. The adjustment motor 63 can drive the main bevel gear 64 to rotate. Because the secondary bevel gear 66 meshes with the main bevel gear 64, the four sets of threaded rods 65 will rotate simultaneously, causing the workpiece clamping seat 62 to move under the cooperation of the limiting groove of the rotating table 61. It can both tension and clamp the inner wall and squeeze and clamp the outer wall. With the cooperation of the precision grinding assembly 76, the inner and outer sides of the workpiece are precision ground separately. This further solves the problem that the existing technology can only perform precision grinding processing on the outer ring of the bearing with a fixed size and cannot be applied to the tight processing of other bearing parts. It can perform precision grinding processing according to the size of the bearing parts.

[0039] Example 3

[0040] Please see Figures 1 to 8 Based on Embodiment 2, in order to increase the clamping resistance applied above the workpiece by the workpiece clamping seat 62 to prevent the workpiece from detaching from the workpiece clamping seat 62 due to centrifugal force during rotation, this embodiment adds an auxiliary pressing mechanism 8. The auxiliary pressing mechanism 8 includes a pressing plate 81 rotatably mounted above the workpiece clamping seat 62. A control motor 82 is fixedly mounted on the upper side wall of the rotating table 61. The output shaft of the control motor 82 is fixedly connected to one end of the rotating shaft of the pressing plate 81. Elastic plates 84 are movably mounted on both sides above the control motor 82. A curved pressing plate 83 is fixedly mounted on the outer side of the elastic plate 84. Magnetic blocks 831 are evenly distributed on the outer side wall of the curved pressing plate 83.

[0041] At the beginning of workpiece installation, the control motor 82 controls the pressing plate 81 to be in a vertical position to facilitate workpiece installation. When the workpiece clamping seat 62 clamps the side wall of the workpiece, the control motor 82 can control the pressing plate 81 to flip so that the pressing plate 81 covers the workpiece. At the same time, the pressing plate 81 exerts a squeezing force on the elastic plate 84. The elastic plate 84 evenly distributes the pressure to the curved pressing plate 83 so that the magnetic block 831 adheres to the upper surface of the metal workpiece to press and block it, so that the workpiece can rotate with the rotating table 61 to facilitate precision grinding. This further solves the problem that the existing technology can only perform precision grinding processing on the outer ring of bearings of fixed size and cannot be applied to the tight processing of other bearing parts. Precision grinding processing can be performed according to the size matching of bearing parts.

[0042] Example 4

[0043] Please see Figures 1 to 8Based on Embodiment 3, in order to increase the stability of the workpiece clamping seat 62 in clamping the workpiece side wall, this embodiment adds an anti-slip mechanism 9. The anti-slip mechanism 9 includes an anti-slip pad 91, a limit rod 92 is fixedly installed on the rear side wall of the anti-slip pad 91, and shrinkage grooves adapted to the limit rod 92 are respectively provided on the inner walls of both sides of the workpiece clamping seat 62. Shock-absorbing spring columns 93 are fixedly installed between the outer surfaces of both sides of the workpiece clamping seat 62 and the rear surface of the anti-slip pad 91.

[0044] When the workpiece clamping seat 62 clamps the metal workpiece, the limiting rod 92 acts as a limit, causing the anti-slip pad 91 to slide and press against the workpiece surface. Because the anti-slip pad 91 is made of non-smooth rubber, it increases the friction of the contact surface. At the same time, the damping spring column 93 has internal damping to alleviate the vibration during workpiece grinding, increasing the stability of the workpiece clamping seat 62 in clamping the side wall of the workpiece. This further solves the problem that the existing technology can only perform precision grinding processing on the outer ring of bearings of fixed size and cannot be applied to the tight processing of other bearing parts. It can perform precision grinding processing according to the size fit of the bearing parts.

[0045] Example 5

[0046] Please see Figures 1 to 8 Based on Embodiment 4, to facilitate workpiece loading and cleaning, this embodiment proposes that the loading mechanism 3 includes a loading platform 31 fixedly installed on the right side of the annular fixed processing table 21, a pusher telescopic rod 32 fixedly installed at the rear end of the loading platform 31, and a pusher plate 33 fixedly installed at the output end of the pusher telescopic rod 32; the ultrasonic cleaning mechanism 4 includes an ultrasonic cleaning tank 41, a transducer installed at the bottom of the inner surface of the ultrasonic cleaning tank 41, an ultrasonic generator connected to the outer wall of the ultrasonic cleaning tank 41, and a cleaning device fixedly installed between the ultrasonic cleaning tank 41 and the adjacent side wall of the annular fixed processing table 21. The guide platform 42 and the upper outer wall of the ultrasonic cleaning tank 41 are fixedly installed with a discharge telescopic rod 43. The output end of the discharge telescopic rod 43 passes through the upper side wall of the ultrasonic cleaning mechanism 4 and is fixedly installed with a discharge plate 44. The upper sides of the ultrasonic cleaning tank 41 are respectively fixedly installed with lifting telescopic rods 46. The output end of the lifting telescopic rods 46 is fixedly installed with a drain basket 45. The outer surface of the drain basket 45 is slidably connected to the inner surface of the ultrasonic cleaning tank 41. The drying mechanism 5 includes a drying table 51 fixedly installed below the annular fixed processing table 21. A fan drying device 52 is provided below the drying table 51.

[0047] The rough-machined metal workpiece is slidably placed on the loading platform 31. The pusher telescopic rod 32 pushes the workpiece to the ring-shaped fixed processing table 21 via the pusher plate 33. The worker places it on the rotating table 61 and clamps it with the workpiece clamping seat 62. After grinding, the workpiece is removed from the rotating table 61 and pushed to the drain basket 45 inside the ultrasonic cleaning tank 41 via the cleaning guide table 42. The lifting telescopic rod 46 lowers the drain basket 45 to below the ultrasonic cleaning tank 41, and the surface of the workpiece is cleaned by ultrasonic waves. Then the lifting telescopic rod 46 rises to reset the drain basket 45. At this time, the unloading telescopic rod 43 extends and the unloading plate 44 pushes the workpiece through the cleaning guide table 42 to the drying table 51. The fan drying equipment 52 dries the workpiece.

[0048] Example 6

[0049] Please see Figure 9 This embodiment proposes a precision metal machining process, which includes the following steps:

[0050] Step 1: Load the workpiece after rough machining;

[0051] Step 2: After internally clamping the workpiece, perform precision grinding on the outer ring;

[0052] Step 3: After clamping the workpiece externally, perform precision grinding on the inner ring;

[0053] Step 4: Clean and dry the workpiece after fine grinding.

[0054] In actual use, the rough-machined metal workpiece is first placed on the loading table 31 by sliding. The pusher telescopic rod 32 pushes the workpiece onto the annular fixed processing table 21 via the pusher plate 33. The worker places it onto the rotating table 61. The adjusting motor 63 drives the main bevel gear 64 to rotate. Because the secondary bevel gear 66 meshes with the main bevel gear 64, the four sets of threaded rods 65 rotate simultaneously, causing the workpiece clamping seat 62 to move under the cooperation of the limiting groove of the rotating table 61, thus tensioning and clamping the inner wall of the workpiece. Motor 82 controls the pressing plate 81 to flip so that it covers the workpiece. Simultaneously, the pressing plate 81 exerts pressure on the elastic plate 84, which evenly distributes the pressure to the curved pressing plate 83, causing the magnetic block 831 to adhere to the upper surface of the metal workpiece for pressing and blocking. Then, by starting the drive motor 72, its output shaft drives the double-threaded rod 73 to rotate, causing the moving slider 74 to move relative to the limit rod, adjusting the position of the telescopic rod 75. The telescopic rod 75 extends, bringing the precision grinding assembly 76 close to the outer surface of the metal workpiece. The main motor 22 drives the drive gear 23 to rotate. Because the gear ring 611 meshes with the drive gear 23, the rotating table 61 will drive the workpiece to rotate, which facilitates the precision grinding assembly 76 to perform precision grinding on the outer wall of the workpiece. The workpiece is then manually reinstalled, and the workpiece clamping seat 62, together with the pressing plate 81, clamps the outer wall of the workpiece. The telescopic rod 75 is then adjusted to fit against the inner wall of the workpiece. The rotating table 61 rotates, causing the precision grinding assembly 76 to perform precision grinding on the inner wall of the workpiece. Finally, the precision grinding process is completed, and the workpiece is removed. The rotating table 61 pushes the workpiece onto the drain basket 45 inside the ultrasonic cleaning tank 41 via the cleaning guide table 42. When the lifting telescopic rod 46 operates, the drain basket 45 descends below the ultrasonic cleaning tank 41, and the surface of the workpiece is cleaned by ultrasonic waves. After cleaning, the lifting telescopic rod 46 operates to rise and reset the drain basket 45. At this time, the unloading telescopic rod 43 extends and the unloading plate 44 pushes the workpiece onto the drying table 51 through the bottom of the cleaning guide table 42. The fan drying equipment 52 operates to dry the workpiece, thus completing the precision machining of the metal workpiece.
