A drilling and grinding composite processing equipment for electric shaver mesh covers

Abstract

This invention belongs to the field of shaver component processing technology, and provides a composite processing equipment for drilling and polishing electric shaver mesh covers. It includes a processing table, a rotary workstation turntable, multiple sets of synchronous clamping mechanisms, a workstation drive assembly, and a matching magnetic drive mechanism. The workstation turntable has at least four independent workstation slots evenly distributed circumferentially, sequentially matching the loading, drilling, double-sided polishing, and unloading workstations. Each workstation slot independently rotates and assembles the clamping mechanism. An independent clamping electromagnet is configured below the drilling workstation to achieve only axial positioning and clamping of the mesh cover. A clamping drive mechanism integrating magnetic attraction and torque output is configured below the polishing workstation, which can simultaneously complete the mesh cover clamping and self-rotation drive. This invention solves the industry pain points of existing shaver mesh cover drilling and double-sided polishing processes, which involve separate equipment processing, large process transfer errors, the need for secondary clamping for both front and back polishing, easy deformation of thin-walled mesh covers, and drilling alignment misalignment. It achieves continuous composite processing with four workstations on a single machine, eliminating the need for secondary workpiece disassembly and assembly.

Description

Technical Field

[0001] This invention belongs to the field of razor parts processing technology, and particularly relates to a drilling and grinding composite processing equipment for electric razor mesh covers. Background Technology

[0002] The electric shaver's mesh cover is a thin-walled, ring-shaped stainless steel component, with a wall thickness of only 0.12-0.25mm. It is the core component of the shaver, ensuring a close fit to the face and blocking beard hairs. The manufacturing process requires three core steps: positioning drilling, inner ring burr removal, and outer ring surface polishing. Currently, the mainstream processing methods in the industry have three major drawbacks:

[0003] 1. Separate processing steps: Drilling and internal and external grinding are processed in three separate steps using three independent machines. The workpiece needs to be manually disassembled and transported three times. The thin-walled stainless steel mesh cover has extremely low rigidity. Multiple clamping can easily cause extrusion deformation and end face warping, with a scrap rate of over 12%. At the same time, multiple clamping will cause coaxiality deviation, resulting in misalignment between the drill hole position and the grinding pattern of the mesh cover, affecting the smoothness of shaving.

[0004] 2. Defects of double-sided grinding process: Existing grinding equipment only supports single-sided grinding. The mesh cover needs to be manually disassembled and then clamped in the opposite direction. The positioning error of manual turning is large, and it is easy to cause uneven grinding thickness of the outer ring. Moreover, manual turning cannot match the pace of automated production line, resulting in low single-machine capacity.

[0005] 3. Poor versatility of clamping structure: The drilling process requires the workpiece to be absolutely stationary to prevent hole displacement, and the grinding process requires the workpiece to rotate at low speed to ensure grinding uniformity. Existing fixtures cannot simultaneously meet the two working conditions of "static clamping for drilling and dynamic rotational grinding", so two sets of fixtures can only be split, resulting in large equipment footprint and high modification costs. Summary of the Invention

[0006] The purpose of this invention is to provide a drilling and grinding composite processing device for electric shaver mesh covers, which aims to solve the technical problems of low productivity of manual clamping and the inability to grind the inner surface in the prior art, resulting in blade jamming and severe wear, thus reducing the service life of the shaver.

[0007] This invention is implemented as follows: a combined drilling and polishing processing device for an electric shaver mesh cover includes a processing table. A mounting cylinder is fixedly connected to the processing table, and a workstation turntable is rotatably mounted on the mounting cylinder via bearings. The workstation turntable has multiple workstation slots, at least four in total: a loading station, a drilling station, a polishing station, and a unloading station. A clamping mechanism is rotatably mounted in each workstation slot. The clamping mechanism is used to place and clamp the mesh cover to be processed during the polishing process. The clamping mechanism can flip the mesh cover to be processed. The processing table is also equipped with an installation ring, which is located below the station turntable. The installation ring is equipped with a clamping electromagnet and a clamping drive mechanism. The clamping electromagnet is located below the drilling station, and the clamping drive mechanism is located below the grinding station. The clamping electromagnet is used to drive the clamping mechanism to clamp the mesh cover to be processed. The clamping drive mechanism is used to drive the clamping mechanism to clamp the mesh cover to be processed and drive the clamping mechanism to rotate so as to grind the mesh cover to be processed.

[0008] The clamping mechanism includes a turntable, a clamping assembly, and a flipping assembly. The turntable is rotatably installed in the work station slot. The clamping assembly is installed on the turntable. The flipping assembly is installed on the clamping assembly. Both the clamping electromagnet and the clamping drive mechanism can drive the clamping assembly to clamp the mesh cover to be processed. When the mesh cover to be processed is being polished, the flipping assembly can flip the mesh cover to be processed so that both sides of the mesh cover to be processed can be polished.

[0009] The processing table is also equipped with a power unit. The output end of the power unit is connected to one end of the station turntable.

The flipping assembly is installed on the two sliders.

[0012] The bottom of the turntable is provided with a first sliding groove, and a lifting block is slidably installed inside the first sliding groove. Both sides of the lifting block are fixedly connected with extrusion rods, and the ends of the two extrusion rods are fixedly connected with bent rods. The opposite sides of the two sliders are provided with inner cavities, and inclined platforms are fixedly connected inside the inner cavities. The ends of the bent rods extend into the inner cavities and abut against the surface of the inclined platforms. The bent rods are U-shaped rods. The bottom of the lifting block is fixedly connected with a first connecting column, and an iron plate that cooperates with the clamping electromagnet and the clamping drive mechanism is fixedly installed at the end of the first connecting column.

[0013] Further technical solution: The flipping assembly includes two upright plates, which are respectively fixedly connected to the top of two sliders. A micro motor is fixedly installed on the opposite sides of the two upright plates. The output shaft of the micro motor passes through the upright plate and is fixedly connected to a flipping plate. An arc-shaped clamping plate is fixedly connected to the side of the two flipping plates. A rubber pad is provided on the inner side of the two arc-shaped clamping plates.

[0014] Further technical solution: The clamping drive mechanism includes a ring electromagnet and a second servo motor. The top of the mounting ring is provided with a mounting groove. The ring electromagnet is fixedly installed in the mounting groove by a ring frame. The second servo motor is fixedly installed at the bottom of the mounting groove. The output shaft of the second servo motor is fixedly installed with a drive protrusion. The bottom of the iron plate is provided with a drive inner groove that cooperates with the drive protrusion.

[0015] Further technical solution: The power component includes a mounting frame, which is fixedly installed on the bottom of the processing table. A first servo motor is fixedly installed on the mounting frame. A connecting pipe is fixedly connected to the bottom of the workstation turntable. One end of the connecting pipe passes through the mounting cylinder. A transmission pair is connected between the output shaft of the first servo motor and the connecting pipe.

[0016] A further technical solution: The drilling assembly includes a second telescopic rod, which is fixedly mounted on a fixed frame. A second linear module is fixedly mounted on the movable end of the second telescopic rod. A third linear module is fixedly mounted on the output end of the second linear module. The third linear module is perpendicularly distributed to the second linear module. A drilling motor is fixedly mounted on the output end of the third linear module. A drill bit is mounted on the output shaft of the drilling motor.

[0017] Further technical solution: The grinding assembly includes a first telescopic rod, which is fixedly installed on a fixed frame. A first linear module is fixedly installed at the movable end of the first telescopic rod. A grinding motor is fixedly installed at the output end of the first linear module. A connecting rod is fixedly installed on the output shaft of the grinding motor. A grinding head is fixedly installed at the end of the connecting rod.

[0018] A further technical solution: A fixed cover is installed at the bottom of the processing table, and a second connecting column is fixedly installed at the top of the fixed cover. The second connecting column passes through the connecting pipe and extends to the top of the workstation turntable. A fixed plate is fixedly connected to the top of the second connecting column, and the fixed frame is fixedly installed on the fixed plate.

[0019] Further technical solution: This equipment is equipped with a PLC programmable controller to uniformly control all power components and automatically complete the drilling and grinding processes.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. Integrated operation reduces costs and increases efficiency: Drilling and double-sided grinding are integrated into a single rotary machine, eliminating the need for workpiece transfer across equipment and secondary clamping, thus reducing the scrap rate of mesh covers; the four-station parallel mode increases production capacity, and a single machine replaces three separate machines, reducing equipment procurement costs.

[0022] 2. Dual-condition compatible clamping structure: The drilling and grinding conditions are distinguished by an independent dual magnetic attraction mechanism: The drilling station uses a fixed electromagnet, and the workpiece is statically clamped with zero rotation, which prevents drilling offset and edge chipping; The grinding station uses magnetic attraction + torque integrated drive, and the same set of fixtures realizes the workpiece rotation without the need to change the tooling, and the tooling switching time is zero.

[0023] 3. Non-destructive automatic flipping process: The flipping process uses a coaxial micro motor on the end face of the clamping plate. During the flipping process, the mesh cover is always clamped and there is no displacement deviation from the clamp. The grinding texture on the front and back sides is continuously aligned. The silicone rubber pad buffers the clamping, completely eliminating the clamping marks and collapse defects of the thin-walled mesh cover.

[0024] 4. Optimized spatial structure: The central column is suspended and fixed, eliminating the side support installation structure, which reduces the overall footprint of the equipment and makes it suitable for the compact layout of the workshop assembly line; the hollow connecting pipe is coaxially arranged with the central column without contact, avoiding rotational interference.

[0025] 5. Compatible with multiple product specifications. The displacement stroke of the three-axis drilling module and the two-axis grinding module is adjustable, and the arc-shaped clamping plate can be quickly replaced. It can be used with the full range of shaver mesh covers with an outer diameter of 18-28mm. The equipment has strong versatility and does not require specific mold modification.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0037] like Figures 1-8As shown, this invention provides a drilling and polishing composite processing device for an electric shaver mesh cover. It includes a processing table 1, on which an mounting cylinder 13 is fixedly connected. A workstation turntable 9 is rotatably mounted on the mounting cylinder 13 via bearings. The workstation turntable 9 has multiple workstation slots 4, at least four in total: a loading station, a drilling station, a polishing station, and a unloading station. A clamping mechanism 3 is rotatably mounted in each workstation slot 4. The clamping mechanism 3 is used to place and clamp the mesh cover 12 to be processed. During the polishing process, the clamping mechanism 3... The processing table 1 is equipped with a mounting ring 2, which is located below the station turntable 9. The mounting ring 2 is equipped with a clamping electromagnet 14 and a clamping drive mechanism 11. The clamping electromagnet 14 is located below the drilling station, and the clamping drive mechanism 11 is located below the grinding station. The clamping electromagnet 14 is used to drive the clamping mechanism 3 to clamp the mesh cover 12 to be processed. The clamping drive mechanism 11 is used to drive the clamping mechanism 3 to clamp the mesh cover 12 to be processed and to drive the clamping mechanism 3 to rotate so as to grind the mesh cover 12 to be processed.

[0038] The clamping mechanism 3 includes a turntable 31, a clamping assembly, and a flipping assembly. The turntable 31 is rotatably installed in the work station slot 4. The clamping assembly is installed on the turntable 31, and the flipping assembly is installed on the clamping assembly. The clamping electromagnet 14 and the clamping drive mechanism 11 can both drive the clamping assembly to clamp the mesh cover 12 to be processed. When the mesh cover 12 to be processed is being polished, the flipping assembly can flip the mesh cover 12 to be processed so that both sides of the mesh cover 12 to be processed can be polished.

[0039] The processing table 1 is also equipped with a power component 10. The output end of the power component 10 is connected to one end of the station turntable 9. The power component 10 is used to drive the station turntable 9 to rotate, so as to switch the position of the mesh cover 12 to be processed, so that the mesh cover 12 to be processed can be loaded, drilled, polished and unloaded in sequence.

[0040] The processing table 1 is also equipped with a fixing frame 6, on which a drilling assembly 8 and a grinding assembly 7 are installed. The drilling assembly 8 and the grinding assembly 7 are respectively installed above the drilling station and the grinding station. The drilling assembly 8 and the grinding assembly 7 are respectively used to drill holes and grind the mesh cover 12 to be processed.

[0041] Specifically, the worker manually places the mesh cover 12 to be processed on the output end of the flipping component, starts the power component 10, and the power component 10 drives the station turntable 9 to rotate 90° (one station), rotating the mesh cover 12 to be processed to the drilling station. The clamping electromagnet 14 is then activated, driving the clamping component to clamp the mesh cover 12. Then, the drilling component 8 is activated, drilling holes in the mesh cover 12. After drilling is completed, the power component 10 is activated again, and the power component 10 drives the mesh cover 12 to be processed to rotate one station again, rotating the drilled mesh cover 12 to the drilling station. Rotate to the polishing station, start the clamping drive mechanism 11, first clamp the mesh cover 12 to be processed, and then drive the turntable 31 to rotate. The turntable 31 drives the mesh cover 12 to be processed to rotate, and then the polishing component 7 polishes one side of the mesh cover 12 to be processed. After polishing one side, the flipping component drives the mesh cover 12 to be processed to be flipped, and then the polishing component 7 polishes it again. This can achieve polishing of both sides of the mesh cover 12 to be processed, improving the quality of the razor mesh cover. Finally, rotate the mesh cover 12 to be processed to the unloading station, and the worker unloads it manually or by machine.

[0042] In addition, after the mesh cover 12, which has been loaded, is rotated to the drilling station, the workers can continue to load materials to achieve continuous processing.

[0043] The present invention provides a drilling and grinding composite processing equipment for an electric shaver mesh cover. In this embodiment, the clamping assembly includes two sliders 32, and the top of the turntable 31 has two second slide grooves 313. The two sliders 32 are slidably installed in the two second slide grooves 313 respectively. A compression spring 314 is also connected between the two sliders 32. The flipping assembly is installed on the two sliders 32.

[0044] The bottom of the turntable 31 is provided with a first slide groove 310. A lifting block 39 is slidably installed inside the first slide groove 310. Both sides of the lifting block 39 are fixedly connected with a pressing rod 312. The ends of the two pressing rods 312 are fixedly connected with a bent rod 34. The opposite sides of the two sliders 32 are provided with an inner cavity 33. An inclined platform 35 is fixedly connected inside the inner cavity 33. The end of the bent rod 34 extends into the inner cavity 33 and abuts against the surface of the inclined platform 35. The bent rod 34 is a U-shaped rod. The bottom of the lifting block 39 is fixedly connected with a first connecting post 38. The end of the first connecting post 38 is fixedly installed with an iron plate 36 that cooperates with the clamping electromagnet 14 and the clamping drive mechanism 11.

[0045] Specifically, the turntable 31 has two sliding holes 311 that are adapted to the extrusion rod 312.

[0046] When the turntable 31 rotates to the drilling position, the clamping electromagnet 14 is located directly below the iron plate 36. When the clamping electromagnet 14 is activated, it attracts the iron plate 36. The attraction force is greater than the elastic force of the compression spring 314, so the iron plate 36 will drive the lifting block 39 to descend through the first connecting column 38. The lifting block 39 descends through the extrusion rod 312 and the bending rod 34. The bending rod 34 extrudes the inclined platform 35 and drives the inclined platform 35 and the slider 32 to move towards the center of the turntable 31. Then the two sliders 32 drive the flipping assembly to clamp the mesh cover 12 to be processed.

[0047] When switching workstations, the power supply to the clamping electromagnet 14 is disconnected. Under the elastic force of the compression spring 314, the two sliders 32 move in opposite directions. The inclined platform 35 then drives the bent rod 34 and the pressing rod 312 to move upward, causing the iron plate 36 to retract into the workstation turntable 9, thus avoiding affecting the movement of the clamping mechanism 3.

[0048] The present invention provides a drilling and polishing composite processing device for an electric shaver mesh cover. In this embodiment, the flipping assembly includes two upright plates 315, which are respectively fixedly connected to the top of two sliders 32. A micro motor 316 is fixedly installed on the opposite sides of the two upright plates 315. The output shaft of the micro motor 316 passes through the upright plates 315 and is fixedly connected to a flipping disc 317. An arc-shaped clamping plate 318 is fixedly connected to the side of each of the two flipping discs 317. A rubber pad 319 is provided on the inner side of each of the two arc-shaped clamping plates 318.

[0049] Specifically, the inner diameter of the two rubber pads 319 is slightly smaller than the outer diameter of the mesh cover 12 to be processed, and the two rubber pads 319 can form a complete ring.

[0050] To drive the two micro motors 316, an electric slip ring can be installed between the mounting ring 2 and the station turntable 9, and between the station turntable 9 and the turntable 31 to provide power to the micro motors 316. Since the screen cover 12 to be processed is only flipped during grinding, the electric slip ring only needs to be installed below the grinding station. After the clamping mechanism 3 rotates to the grinding station, the two micro motors 316 can be energized, thus avoiding all micro motors 316 being energized at the same time.

[0051] When the mesh cover 12 to be processed is clamped, the two sliders 32 drive the two vertical plates 315 to move towards each other, and the two vertical plates 315 drive the two arc clamping plates 318 to clamp the mesh cover 12 to be processed. The rubber pad 319 is interference-fitted with the side wall of the mesh cover 12 to be processed, so as to clamp the mesh cover 12 to be processed.

[0052] In addition, the initial axial distance between the two arc-shaped clamps 318 is less than the folded edge width of the mesh cover 12 to be processed, so that the workers can directly place the mesh cover 12 to be processed upside down between the two arc-shaped clamps 318. The mesh cover 12 to be processed is set on the two rubber pads 319, which facilitates the loading and unloading of the mesh cover 12 to be processed. When clamping the mesh cover 12 to be processed, the two rubber pads 319 can directly clamp the side of the mesh cover 12 to be processed.

[0053] Furthermore, when drilling holes in the mesh cover 12 to be processed, the drilling assembly 8 will drill holes in the mesh cover 12 to be processed from top to bottom. The folded edge of the mesh cover 12 to be processed upside down will be blocked by the arc-shaped clamp 318, so that the mesh cover 12 to be processed can stably withstand the drilling force from the drilling assembly 8, thus avoiding the situation where the drilling quality decreases due to the offset of the mesh cover 12 to be processed.

[0054] During grinding, the output end of the grinding component 7 is first inserted into the screen cover 12 to be processed to grind the inner side of the screen cover 12. After the inner side is ground, the grinding component 7 is raised, and then the two micro motors 316 are started. The two micro motors 316 simultaneously drive the screen cover 12 to be processed to rotate 180°, so that the outer side of the screen cover 12 is exposed below the output end of the grinding component 7. Then the grinding component 7 can be started to grind the outer side of the screen cover 12.

[0055] The present invention provides a drilling and grinding composite processing device for an electric shaver mesh cover. In this embodiment, the clamping drive mechanism 11 includes an annular electromagnet 112 and a second servo motor 115. The top of the mounting ring 2 is provided with a mounting groove 114. The annular electromagnet 112 is fixedly installed in the mounting groove 114 by an annular frame 111. The second servo motor 115 is fixedly installed at the bottom of the mounting groove 114. The output shaft of the second servo motor 115 is fixedly installed with a drive protrusion 113. The bottom of the iron plate 36 is provided with a drive inner groove 37 that cooperates with the drive protrusion 113.

[0056] Specifically, the drive protrusion 113 is located in the middle of the annular electromagnet 112. When the clamping mechanism 3 is in the grinding position, the annular electromagnet 112 is located directly below the iron plate 36.

[0057] During polishing, the annular electromagnet 112 is activated first. The annular electromagnet 112 attracts the iron disc 36 and causes the iron disc 36 to descend, thereby clamping the mesh cover 12 to be processed. At the same time, the drive protrusion 113 is inserted into the drive inner groove 37, and the second servo motor 115 is activated. The second servo motor 115 drives the drive protrusion 113 to rotate, and the drive protrusion 113 drives the iron disc 36 to rotate. The iron disc 36 drives the turntable 31 to rotate through the first connecting column 38 and the lifting block 39. The turntable 31 drives the mesh cover 12 to be processed to rotate through the slider 32 and the vertical plate 315, so as to polish the surface of the mesh cover 12 to be processed.

[0058] During polishing, the output end of the polishing component 7 is first inserted into the inside of the mesh cover 12 to polish the inner side of the mesh cover 12. Then, the mesh cover 12 is flipped over so that the output end of the polishing component 7 contacts the top of the outer surface of the mesh cover 12 to polish the top of the outer side of the mesh cover 12. Finally, the output end of the polishing component 7 is moved to the side of the mesh cover 12, and then the second servo motor 115 is started to drive the mesh cover 12 to rotate, so that the mesh cover 12 and the output end of the polishing component 7 move relative to each other to polish the side of the mesh cover 12, thereby making the outer surface of the mesh cover 12 smoother and improving the polishing effect of the mesh cover 12.

[0059] The present invention provides a drilling and polishing composite processing equipment for an electric shaver mesh cover. In this embodiment, the power component 10 includes a mounting frame 103, which is fixedly installed on the bottom of the processing table 1. A first servo motor 102 is fixedly installed on the mounting frame 103. A connecting pipe 91 is fixedly connected to the bottom of the workstation turntable 9. One end of the connecting pipe 91 passes through the mounting cylinder 13. A transmission pair 101 is connected between the output shaft of the first servo motor 102 and the connecting pipe 91.

[0060] Specifically, transmission pair 101 is a belt pair.

[0061] The first servo motor 102 can drive the connecting pipe 91 to rotate through the transmission pair 101. The connecting pipe 91 drives the station turntable 9 to rotate, and the station turntable 9 will drive multiple clamping mechanisms 3 to rotate, so as to switch the processing position of the mesh cover 12 to be processed.

[0062] The present invention provides a drilling and polishing composite processing device for an electric shaver mesh cover. In this embodiment, the drilling assembly 8 includes a second telescopic rod 81, which is fixedly mounted on a fixed frame 6. A second linear module 82 is fixedly mounted on the movable end of the second telescopic rod 81, and a third linear module 83 is fixedly mounted on the output end of the second linear module 82. The third linear module 83 is perpendicularly distributed to the second linear module 82. A drilling motor 84 is fixedly mounted on the output end of the third linear module 83, and a drill bit 85 is mounted on the output shaft of the drilling motor 84.

[0063] Specifically, drill bit 85 is located above the drilling station.

[0064] During drilling, the second telescopic rod 81 adjusts the Z-axis position of the drill bit 85, the second linear module 82 adjusts the Z-axis position of the drill bit 85, and the third linear module 83 adjusts the Y-axis position of the drill bit 85, so that drilling can be performed at any point on the mesh cover 12 to be processed.

[0065] The present invention provides a drilling and polishing composite processing device for an electric shaver mesh cover. In this embodiment, the polishing component 7 includes a first telescopic rod 71, which is fixedly installed on a fixed frame 6. A first linear module 72 is fixedly installed at the movable end of the first telescopic rod 71. A polishing motor 73 is fixedly installed at the output end of the first linear module 72. A connecting rod 74 is fixedly installed on the output shaft of the polishing motor 73. A polishing head 75 is fixedly installed at the end of the connecting rod 74.

[0066] Specifically, the grinding head 75 is located above the grinding station, and the diameter of the grinding head 75 is smaller than the inner diameter of the mesh cover 12 to be processed.

[0067] The first telescopic rod 71 can adjust the Z-axis position of the grinding head 75 to make the grinding head 75 contact the surface of the mesh cover 12 to be processed, and the first linear module 72 can adjust the Y-axis position of the grinding head 75 to make the grinding head 75 cover the entire surface of the mesh cover 12 to be processed.

[0068] Initially, the axis of the grinding head 75 is aligned with the axis of the mesh cover 12 to be processed. During grinding, the grinding head 75 first contacts the inner surface of the mesh cover 12, and then the grinding head 75 is gradually moved to the outer side of the mesh cover 12. During this process, the clamping drive mechanism 11 drives the mesh cover 12 to rotate, so that the grinding head 75 can cover the entire surface of the mesh cover 12. When grinding the outer side of the mesh cover 12, the top of the mesh cover 12 is ground first. Then, the first linear module 72 moves the grinding head 75 to the side of the mesh cover 12 and lowers the height of the grinding head 75 so that the grinding head 75 contacts the side of the mesh cover 12. The clamping drive mechanism 11 drives the mesh cover 12 to rotate, so that the grinding head 75 can grind the entire outer side of the mesh cover 12.

[0069] The present invention provides a drilling and polishing composite processing equipment for an electric shaver mesh cover. In this embodiment, a fixing cover 51 is installed at the bottom of the processing table 1, and a second connecting column 52 is fixedly installed on the top of the fixing cover 51. The second connecting column 52 passes through the connecting pipe 91 and extends to the top of the workstation turntable 9. A fixing plate 5 is fixedly connected to the top of the second connecting column 52, and the fixing frame 6 is fixedly installed on the fixing plate 5.

[0070] Specifically, the mounting bracket 6 can be installed on top of the mounting plate 5, eliminating the need to install it on the side of the processing table 1, thus reducing the footprint of the device.

[0071] This equipment is equipped with a PLC programmable controller to control all power components and automatically complete the drilling and grinding processes.

[0072] Workflow:

[0073] This equipment adopts a four-station parallel asynchronous processing mode, with all four stations operating simultaneously. The specific timing steps are as follows:

[0074] Step S1: Manual / automatic loading at the loading station. Under normal conditions, the compression spring 314 pushes the two sets of sliders 32 to open. The distance between the arc-shaped clamps 318 is greater than the outer diameter of the mesh cover. The operator places the mesh cover upside down on the top of the rubber pads 319 on both sides. The folded edges of the mesh cover are secured to the arc-shaped clamps 318. No alignment calibration is required, reducing loading time.

[0075] Step S2: Station switching and transfer. The PLC starts the first servo motor 102, which drives the station turntable 9 to rotate 90° clockwise via belt drive. The first servo motor 102 completes mechanical locking, and the mesh cover is precisely aligned to the drilling station.

[0076] Step S3: Static clamping at the drilling station + drilling operation. The clamping electromagnet 14 below the drilling station is energized, causing the adsorption plate 36 to move downwards, which in turn moves the lifting block 39 and the extrusion rod 312 downwards simultaneously. The bent rod 34 extrudes the inclined platform 35, pushing the two sets of sliders 32 to radially close, and the arc-shaped clamping plate 318 clamps the mesh cover with interference. Subsequently, the second telescopic rod 81 and the double linear module work together to adjust the three-axis coordinates of the drill bit 85, completing the drilling according to the preset hole position. After drilling is completed, the clamping electromagnet 14 is de-energized, and the compression spring 314 pushes the slider 32 to reset and loosen the clamp. At this time, the loading station simultaneously completes the loading of the next mesh cover, achieving parallel operation.

[0077] Step S4: Secondary station switching and transfer. The station turntable 9 rotates 90° again, and the mesh cover is transferred to the grinding station.

[0078] Step S5: Double-sided grinding operation at the grinding station. ① Inner ring grinding: The annular electromagnet 112 is energized to clamp the mesh cover, the drive protrusion 113 is inserted into the drive inner groove 37, the first telescopic rod 71 descends to allow the grinding head 75 to extend into the mesh cover, the second servo motor 115 drives the turntable 31 to rotate at low speed, and the first linear module 72 moves laterally to complete the grinding of the entire inner ring of the mesh cover; ② Automatic flipping: The grinding head 75 is raised to detach from the mesh cover, and the micro motors 316 on both sides rotate the processing table 180° synchronously in the same direction, causing the entire mesh cover to flip over, with a coaxiality error of ≤0.02mm; ③ Outer ring grinding: The grinding head 75 moves down to fit against the top surface and side wall of the outer ring of the mesh cover, and the rotation of the turntable 31 completes the full-area polishing of the outer ring.

[0079] Step S6: Final station switching and unloading. The station turntable 9 rotates 90° to the unloading station, the clamping mechanism 3 automatically releases the clamp, and the robot arm sucks up the material under negative pressure for unloading or manual unloading.

[0080] Parallel processing: Four workstations simultaneously complete one round of feeding, drilling, grinding, and unloading, eliminating process waiting time and increasing the daily output of a single machine to three times that of separate equipment.
