Technical Field
[0001] This invention relates to the field of machining technology, and more specifically, to a machining equipment and method for high-precision micro-components. Background Technology
[0002] In the manufacturing process of miniature precision components (such as miniature sensors, medical device parts, and precision optical elements), high-precision machining is crucial to ensuring their final performance and quality. These components are typically characterized by their small size, complex structure, and special materials (such as being fragile or easily deformable), which places extremely high demands on the clamping and fixing during the machining process.
[0003] When processing micro-precision parts, existing processing equipment generally uses traditional clamps such as three-jaw chucks or simple clamping blocks to axially compress and limit the outer wall of the micro-precision parts. During the processing of micro-precision parts, the cutting force and vibration generated during processing will cause radial displacement between the micro-precision parts and the clamping block, which will lead to problems such as dimensional deviation, excessive form and position error and surface scratches, which will seriously restrict the improvement of processing accuracy and reduce the product yield. Summary of the Invention
[0004] This invention addresses the technical problems existing in the prior art by providing a high-precision micro-precision component processing equipment and method. It solves the problem that existing processing equipment commonly uses traditional clamps such as three-jaw chucks or simple pressure blocks to axially compress and limit the outer wall of micro-precision components during processing. Under the processing loads such as cutting forces and vibrations, radial displacement occurs between the micro-precision component and the pressure block, leading to problems such as dimensional deviations, excessive form and position errors, and surface scratches. This severely restricts the improvement of processing accuracy and results in a decrease in product yield.

[0013] The method for manufacturing high-precision micro-components as described above includes the following steps: Step 1: Place the miniature precision component into the T-slot, with the lower end of the miniature precision component resting on the supporting cylindrical block. Activate the clamping cylinder. The telescopic end of the clamping cylinder drives the arc-shaped vertical block and arc-shaped plate to move. The arc-shaped plate abuts against the miniature precision component. As the arc-shaped vertical block moves toward the miniature precision component, it drives the first lower inclined block and the connecting block to move. The first lower inclined block presses down on the base and the supporting cylindrical block through the second lower inclined block. When the uppermost end of the second lower inclined block moves to the lower end surface of the connecting block, the miniature precision component is completely retracted into the T-slot. Step 2: The telescopic end of the clamping cylinder continues to drive the arc-shaped vertical block to move. Since the arc-shaped plate is against the micro-precision component, it is equivalent to the arc-shaped plate moving away from the micro-precision component. The arc-shaped plate drives the gear column to rotate through the lower gear plate. The gear column drives the upper gear plate and the upper inclined block to move towards the micro-precision component. The inclined surface of the upper inclined block is against the upper edge of the micro-precision component. The upper inclined block presses down on the micro-precision component through the inclined surface. Step 3: When the micro-precision component moves downward, the bearing cylindrical block and the first vertical rod press down on the first sealing slide plate. The first sealing slide plate forces the air at the lower end of the cylindrical tube into the L-shaped tube, increasing the air pressure in the L-shaped tube. The second sealing slide plate moves upward, which in turn drives the second vertical rod and the lower fixing block to move upward. The groove of the lower fixing block abuts against the lower end surface of the micro-precision component. The upper inclined block, together with the lower fixing block, fixes and limits the micro-precision component from above and below, preventing the micro-precision component from shifting during processing, reducing the processing accuracy of the micro-precision component, and improving the processing precision of the micro-precision component. Step 4: After the micro-precision component is clamped and fixed, the processing component processes the micro-precision component. The stepper motor is started, and the output end of the stepper motor drives the first rotating rod and the small gear to rotate. The small gear drives the second rotating rod to rotate through the large gear, which in turn drives the rotating block and the clamped and fixed micro-precision component to rotate. The remaining micro-precision components to be processed can be rotated to the bottom of the processing component for processing. Step 5: After the micro-precision component is processed, the telescopic end of the clamping cylinder drives the arc-shaped vertical block to move away from the micro-precision component. Under the action of the buffer spring, it pushes the arc-shaped plate and the lower toothed plate to move. Through the gear column, it drives the upper toothed plate and the upper inclined block to move away from the micro-precision component, and the upper inclined block separates from the micro-precision component. Step Six: As the arc-shaped vertical block moves away from the micro-precision component, the second lower inclined block moves from the lower end face of the connecting block to the inclined surface of the first lower inclined block. Under the action of the connecting spring, the second lower inclined block moves upward along the inclined surface of the first lower inclined block, thereby driving the base and the supporting cylindrical block to move upward, which in turn drives the finished micro-precision component to move upward. The upper end of the finished micro-precision component moves out of the T-slot, making it easy to remove the finished micro-precision component.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up four circumferentially distributed clamping cylinders to drive the arc plate for radial initial positioning and clamping, and using a clever transmission component, the radial clamping motion is converted into the axial downward movement of the upper inclined block. Combined with the pneumatic linkage of the bottom mechanism, a three-dimensional, multi-point, multi-directional synchronous fixation is achieved by the combined action of the radial, upper edge, and lower end face of the component. This greatly enhances the stability of the component during the processing, effectively suppresses small displacements and vibrations in any direction, and thus ensures extremely high processing accuracy.
[0015] By setting up an ejection assembly consisting of a lower inclined block, a connecting block, and a connecting spring, the base and the processed part can be automatically lifted upwards during the process of the clamping cylinder releasing and driving the arc-shaped vertical block to retract, so that part of it is exposed in the T-slot. This allows the operator or robot to easily remove the processed part, further improving the smoothness of the automated process. Attached Figure Description

This mechanism includes an arc-shaped vertical block 602 that slides within the T-slot, driven by a clamping cylinder 601 (model SMC CQ2B, cylinder diameter 10mm, stroke 10mm). The inner surface of the arc-shaped vertical block 602 is provided with an arc-shaped plate 603 and an upper inclined block 604.

Both the lower gear plate 6052 and the upper gear plate 6053 are meshed with the gear post 6051. A rotating shaft 6054 is fixedly inserted at the center of the 051. Two mounting vertical plates 6055 are symmetrically fixedly connected to the inner wall of the connecting groove. Both ends of the rotating shaft 6054 are rotatably connected to the mounting vertical plates 6055. The upper toothed plate 6053 passes through the side wall of the arc-shaped vertical block 602 and is fixedly connected to the upper inclined block 604. Multiple buffer springs 6031 are fixedly connected to the arc-shaped plate 603. The end of each buffer spring 6031 facing away from the arc-shaped plate 603 is fixedly connected to the inner wall of the connecting groove. The extension end of the clamping cylinder 601 drives the arc-shaped vertical block 602 and the arc-shaped plate 603 to move. The arc-shaped plate 603 abuts against the micro-precision component 5. When the extension end of the clamping cylinder 601 continues to drive the arc-shaped vertical block 602 to move, the upper inclined block 604 moves towards the micro-precision component 5 through the transmission component 605. The inclined surface of the upper inclined block 604 abuts against the upper edge of the micro-precision component 5. The upper inclined block 604 presses down on the micro-precision component 5 through the inclined surface.
[0020] The T-slot has a bottom mechanism 7 in the space formed by placing the bottom of the cylindrical block 4. The bottom mechanism 7 is used to limit the lower edge of the micro-precision component 5 and assist in the placement and removal of the micro-precision component 5. The bottom mechanism 7 includes a base 701, a supporting cylindrical block 702 and a bottom fixing component 704.
[0021] The base 701 has a cavity. The bottom fixing assembly 704 includes a cylindrical tube 7041 fixedly installed in the cavity and multiple L-shaped tubes 7042 circumferentially fixedly connected to the cylindrical tube 7041. A first sealing slide plate 7044 is slidably connected to the inner wall of the cylindrical tube 7041. A first vertical rod 7043 is fixedly connected to the upper end face of the first sealing slide plate 7044. The upper end of the first vertical rod 7043 penetrates the upper end face of the cylindrical tube 7041. The lower end of the bearing cylindrical block 702 penetrates the upper end face of the base 701 and is connected to the first vertical rod 7043. A rod 7043 is fixedly connected. A second sealing slide plate 7045 is slidably connected to the inner wall of each L-shaped tube 7042. A second vertical rod 7046 is fixedly connected to the upper end face of each second sealing slide plate 7045. The upper end of each second vertical rod 7046 passes through the upper end face of the base 701 and is fixedly connected to a lower fixing block 7047. Each lower fixing block 7047 has a groove. A first return spring 7048 is fitted on each first vertical rod 7043. The upper and lower ends of the first return spring 7048 are respectively fixedly connected to the first... On the upper end face of the sealing slide plate 7044 and the upper inner wall of the cylindrical tube 7041, a second return spring 7049 is fitted on each second vertical rod 7046. The upper and lower ends of each second return spring 7049 are respectively fixedly connected to the upper end face of the second sealing slide plate 7045 and the upper inner wall of the L-shaped tube 7042. When the micro-precision component 5 moves downward, it presses down on the first sealing slide plate 7044 through the supporting cylindrical block 702 and the first vertical rod 7043. The first sealing slide plate 7044 forces the air at the lower end of the cylindrical tube 7041 into the L-shaped tube 7042. In the L-shaped tube 7042, the air pressure of the L-shaped tube 7042 is increased, and the second sealing slide plate 7045 moves upward, which in turn drives the second vertical rod 7046 and the lower fixing block 7047 to move upward. The groove of the lower fixing block 7047 abuts against the lower end surface of the micro precision component 5. The upper inclined block 604 cooperates with the lower fixing block 7047 to fix and limit the micro precision component 5 from above and below, so as to prevent the micro precision component 5 from shifting during processing, reducing the processing accuracy of the micro precision component 5, and improving the processing precision of the micro precision component 5.
[0022] An ejection assembly 703 is provided in the T-slot. The ejection assembly 703 includes a first lower inclined block 7031 fixedly connected to the lower end face of four arc-shaped vertical blocks 602 and four connecting blocks 7032 fixedly connected to the upper end face of the base 701. The inclined surfaces of the first lower inclined block 7031 and the connecting blocks 7032 are tangent. Each first lower inclined block 7031 is fixedly connected to a connecting block 7032. A circular groove is opened on the lower end face of the base 701. A circular plate 7034 is slidably connected to the inner wall of the circular groove. A connecting spring 7035 is fixedly connected to the upper end face of the circular plate 7034. The upper end of the connecting spring 7035 is fixedly connected to the inner wall of the circular groove. A rectangular plate 7036 is fixedly connected to the lower end inner wall of the T-slot. The lower end of the circular plate 7034 is fixedly connected to the rectangular plate 7036. As the arc-shaped vertical blocks 602 move toward the micro-precision component 5, they drive the first lower inclined blocks 7031 and the connecting blocks 7032 to move towards the micro-precision component 5. As the connecting block 7032 moves, the first lower inclined block 7031 presses down on the base 701 and the supporting cylindrical block 702 via the second lower inclined block 7033. When the uppermost end of the second lower inclined block 7033 moves to the lower end surface of the connecting block 7032, the micro-precision component 5 is completely inserted into the T-slot. As the arc-shaped vertical block 602 moves away from the micro-precision component 5, the second lower inclined block 7033 moves from the lower end surface of the connecting block 7032 to the inclined surface of the first lower inclined block 7031. Under the action of the connecting spring 7035, the second lower inclined block 7033 moves upward along the inclined surface of the first lower inclined block 7031, thereby driving the base 701 and the supporting cylindrical block 702 to move upward, thus driving the finished micro-precision component 5 to move upward. The upper end of the finished micro-precision component 5 moves out of the T-slot, making it convenient to remove the finished micro-precision component 5. Example 2
[0023] Please see Figure 1This embodiment provides a high-precision micro-precision component processing equipment. A connecting box 2 is fixedly connected to the lower end face of a platform 1. A rotating structure 8 is provided in the connecting box 2. The rotating structure 8 includes a fixed plate 801 fixedly connected to the inner wall of the connecting box 2 and a stepper motor 802 fixedly mounted on the fixed plate 801. A first rotating rod 803 is fixedly connected to the output end of the stepper motor 802. A small gear 804 is fixedly sleeved on the first rotating rod 803. The small gear 804 meshes with a large gear 805. A second rotating rod 806 is fixedly inserted at the center of the large gear 805. The lower part of the second rotating rod 806... The first end is rotatably connected to the fixed plate 801, and the upper end of the second rotating rod 806 is fixedly connected to the lower end face of the rotating block 3. After the micro precision component 5 is clamped and fixed, the processing component 10 processes the micro precision component 5. The stepper motor 802 is started, and the output end of the stepper motor 802 drives the first rotating rod 803 and the pinion 804 to rotate. The pinion 804 drives the second rotating rod 806 to rotate through the large gear 805, which in turn drives the rotating block 3 and the clamped and fixed micro precision component 5 to rotate. The remaining micro precision components 5 to be processed can be rotated to the bottom of the processing component 10 for processing.
[0024] The machining method for high-precision micro-components as described above includes the following steps: Step 1: Place the miniature precision component 5 into the T-slot. The lower end of the miniature precision component 5 rests on the supporting cylindrical block 702. Activate the clamping cylinder 601. The telescopic end of the clamping cylinder 601 drives the arc-shaped vertical block 602 and the arc-shaped plate 603 to move. The arc-shaped plate 603 abuts against the miniature precision component 5. As the arc-shaped vertical block 602 moves toward the miniature precision component 5, it drives the first lower inclined block 7031 and the connecting block 7032 to move. The first lower inclined block 7031 presses down on the base 701 and the supporting cylindrical block 702 through the second lower inclined block 7033. When the uppermost end of the second lower inclined block 7033 moves to the lower end surface of the connecting block 7032, the miniature precision component 5 is completely retracted into the T-slot.
[0025] Step 2: The telescopic end of the clamping cylinder 601 continues to drive the arc-shaped vertical block 602 to move. Since the arc-shaped plate 603 is against the micro-precision component 5, it is equivalent to the arc-shaped plate 603 moving away from the micro-precision component 5. The arc-shaped plate 603 drives the gear column 6051 to rotate through the lower gear plate 6052. The gear column 6051 drives the upper gear plate 6053 and the upper inclined block 604 to move towards the micro-precision component 5. The inclined surface of the upper inclined block 604 abuts against the upper edge of the micro-precision component 5. The upper inclined block 604 presses the micro-precision component 5 downward through the inclined surface.
[0026] Step 3: When the micro-precision component 5 moves downward, the bearing cylindrical block 702 and the first vertical rod 7043 press down on the first sealing slide plate 7044. The first sealing slide plate 7044 squeezes the air at the lower end of the cylindrical tube 7041 into the L-shaped tube 7042, increasing the air pressure in the L-shaped tube 7042. The second sealing slide plate 7045 moves upward, which in turn drives the second vertical rod 7046 and the lower fixing block 7047 to move upward. The groove of the lower fixing block 7047 abuts against the lower end surface of the micro-precision component 5. The upper inclined block 604, together with the lower fixing block 7047, fixes and limits the micro-precision component 5 from above and below, preventing the micro-precision component 5 from shifting during processing, reducing the processing accuracy of the micro-precision component 5, and improving the processing precision of the micro-precision component 5.
[0027] Step 4: After the micro-precision component 5 is clamped and fixed, the processing component 10 processes the micro-precision component 5. The stepper motor 802 is started, and the output end of the stepper motor 802 drives the first rotating rod 803 and the pinion 804 to rotate. The pinion 804 drives the second rotating rod 806 to rotate through the large gear 805, which in turn drives the rotating block 3 and the clamped and fixed micro-precision component 5 to rotate. The remaining micro-precision components 5 to be processed can be rotated to the bottom of the processing component 10 for processing.
[0028] Step 5: After the micro-precision component 5 is processed, the telescopic end of the clamping cylinder 601 drives the arc-shaped vertical block 602 to move away from the micro-precision component 5. Under the action of the buffer spring 6031, the arc-shaped plate 603 and the lower toothed plate 6052 are pushed to move. Through the gear column 6051, the upper toothed plate 6053 and the upper inclined block 604 are driven to move away from the micro-precision component 5, and the upper inclined block 604 separates from the micro-precision component 5.
[0029] Step Six: As the arc-shaped vertical block 602 moves away from the micro-precision component 5, the second lower inclined block 7033 moves from the lower end face of the connecting block 7032 to the inclined surface of the first lower inclined block 7031. Under the action of the connecting spring 7035, the second lower inclined block 7033 moves upward along the inclined surface of the first lower inclined block 7031, thereby driving the base 701 and the supporting cylindrical block 702 to move upward, thereby driving the finished micro-precision component 5 to move upward. The upper end of the finished micro-precision component 5 moves out of the T-slot, making it convenient to remove the finished micro-precision component 5.

9. A method for machining high-precision micro-precision components, applied to the machining equipment for high-precision micro-precision components as described in any one of claims 1-7, characterized in that, Includes the following steps: Step 1: Place the micro precision component (5) into the T-slot. Place the lower end of the micro precision component (5) on the supporting cylindrical block (702). Start the clamping cylinder (601). The telescopic end of the clamping cylinder (601) drives the arc-shaped vertical block (602) and the arc-shaped plate (603) to move. The arc-shaped plate (603) abuts against the micro precision component (5). As the arc-shaped vertical block (602) moves toward the micro precision component (5), it drives the first lower inclined block (7031) and the connecting block (7032) to move. The first lower inclined block (7031) presses down on the base (701) and the supporting cylindrical block (702) through the second lower inclined block (7033). When the uppermost end of the second lower inclined block (7033) moves to the lower end surface of the connecting block (7032), the micro precision component (5) is completely inserted into the T-slot. Step 2: The telescopic end of the clamping cylinder (601) continues to drive the arc-shaped vertical block (602) to move. The arc-shaped plate (603) is pressed against the micro precision component (5), which is equivalent to the arc-shaped plate (603) moving away from the micro precision component (5). The arc-shaped plate (603) drives the gear column (6051) to rotate through the lower gear plate (6052). The gear column (6051) drives the upper gear plate (6053) and the upper inclined block (604) to move towards the micro precision component (5). The inclined surface of the upper inclined block (604) presses against the upper edge of the micro precision component (5). The upper inclined block (604) presses down on the micro precision component (5) through the inclined surface. Step 3: When the micro precision component (5) moves down, the bearing cylindrical block (702) and the first vertical rod (7043) press down the first sealing slide plate (7044). The first sealing slide plate (7044) squeezes the air at the lower end of the cylindrical tube (7041) into the L-shaped tube (7042). The air pressure in the L-shaped tube (7042) increases, and the second sealing slide plate (7045) moves upward, which in turn drives the second vertical rod (7046) and the lower fixing block (7047) to move upward. The groove of the lower fixing block (7047) abuts against the lower end surface of the micro precision component (5). The upper inclined block (604) cooperates with the lower fixing block (7047) to fix and limit the micro precision component (5) from above and below, so as to avoid the micro precision component (5) from shifting during processing, reducing the processing accuracy of the micro precision component (5), and improving the processing precision of the micro precision component (5). Step 4: After the micro precision component (5) is clamped and fixed, the processing component (10) processes the micro precision component (5). The stepper motor (802) is started. The output end of the stepper motor (802) drives the first rotating rod (803) and the pinion (804) to rotate. The pinion (804) drives the second rotating rod (806) to rotate through the large gear (805), which in turn drives the rotating block (3) and the clamped and fixed micro precision component (5) to rotate. The remaining micro precision components (5) to be processed can be rotated to the bottom of the processing component (10) for processing. Step 5: After the micro precision component (5) is processed, the telescopic end of the clamping cylinder (601) drives the arc-shaped vertical block (602) to move away from the micro precision component (5). Under the action of the buffer spring (6031), the arc plate (603) and the lower tooth plate (6052) are pushed to move. Through the gear column (6051), the upper tooth plate (6053) and the upper inclined block (604) are driven to move away from the micro precision component (5). The upper inclined block (604) separates from the micro precision component (5). Step 6: As the arc-shaped vertical block (602) moves away from the micro-precision component (5), the second lower inclined block (7033) moves from the lower end face of the connecting block (7032) to the inclined surface of the first lower inclined block (7031). Under the action of the connecting spring (7035), the second lower inclined block (7033) moves upward along the inclined surface of the first lower inclined block (7031), thereby driving the base (701) and the supporting cylindrical block (702) to move upward, thereby driving the finished micro-precision component (5) to move upward. The upper end of the finished micro-precision component (5) moves out of the T-slot, making it convenient to take out the finished micro-precision component (5).
