Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing precision machining technology, and in particular to an automatic grinding workstation for parts surfaces. Background Technology

[0002] With the rapid development of intelligent manufacturing technology, automated grinding equipment has been increasingly widely used in the field of precision parts processing. As a key component in semiconductor manufacturing equipment, the aluminum mold vacuum chamber has extremely high requirements for its sealing surface in terms of airtightness, vacuum performance, corrosion resistance, and long-term stability. However, the automated grinding of the surface of the aluminum mold vacuum chamber still faces many technical challenges, specifically in the following aspects:

[0003] First, the consistency and uniformity of the surface polishing of the parts must be extremely high, requiring zero defects on the surface. Any minor defects (such as fish scale patterns, surface color differences, or uneven gloss) are unacceptable.

[0004] Secondly, the cutting marks from the pre-processing of cavity parts cannot be completely consistent, and the depth of the cutting marks themselves is inconsistent. During the grinding process, all cutting marks need to be removed, while preventing the parts from having excessive removal allowance and causing dimensional deviations. This poses a great challenge to the adaptability of the equipment.

[0005] Third, while the amount of material removed and the roughness of the surface can be digitized, there is no clear quantitative standard for the surface texture. It can only be inspected by manual visual inspection. The lack of a quantifiable standard makes it impossible to form a fully closed-loop control based on the surface texture effect, which places extremely high demands on the reliability of automated equipment.

[0006] Fourth, in addition to the overall consistency, cavity parts also have complex features such as curved surfaces, corners, transition fillets, sealing grooves and trenches, which require precise local processing. This places extremely high demands on machining tools and processes.

[0007] To address the aforementioned problems, those skilled in the art have explored various automated polishing solutions. For example, Chinese Patent CN114346880A discloses a polishing machine material changing device and a polishing machine. The technical solution is as follows: In automated polishing operations, when the polishing head needs material changing, the polishing head moves towards a material-tearing mechanism. The material-tearing mechanism uses the relative movement between the support platform and the polishing head to remove the old consumable material from the polishing head. After the old consumable material is removed, the polishing head moves to a feeding mechanism, where a new consumable material is provided for adhesion. However, this prior art has the following shortcomings:

[0008] (1) Its tearing mechanism achieves the "removal" of old consumables through the relative movement of the bearing table and the polishing head. This removal method is suitable for situations where the adhesion between consumables and polishing head is small. However, for consumables that are stuck together very tightly due to the large pressure during the polishing process, simple relative movement removal is difficult to effectively separate them, which can easily lead to consumable residue or tearing.

[0009] (2) The device lacks a structure for removing residual consumables after tearing. The fragments or residues generated during the tearing process may affect the accuracy of subsequent feeding operations.

[0010] (3) The replacement of old and new consumables depends on the overall movement and positioning of the polishing head. It lacks an active centering calibration mechanism for the eccentricity of the polishing head. In the case of eccentricity of the polishing head, it is difficult to guarantee the concentricity of the new consumables.

[0011] For example, Chinese patent CN222779376U discloses an automatic consumable replacement device for an eccentric grinding and polishing machine. Its technical solution involves using a rotary motor to drive a rotating shaft to rotate axially, positioning the eccentric grinding head mounted on the rotating shaft directly opposite the consumable replacement structure. An encoder identifies the rotational position of the eccentric grinding head, and adjustments are made between the rotational and replacement positions based on a pre-set replacement position. Finally, the consumables on the eccentric grinding head are replaced via the consumable replacement structure. However, this prior art still has the following shortcomings:

[0012] (1) The device mainly solves the problem of rotation positioning of the eccentric shaft grinding head, but lacks an effective mechanical structure design for the specific tearing method of consumables. It only covers the two functions of tearing and loading through the general description of "consumable replacement structure", without providing a specific and feasible technical solution for how to overcome the strong adhesion between consumables and grinding head during the tearing process.

[0013] (2) This device is designed for the replacement of consumables for eccentric shaft grinding heads. However, for grinding tools with special spatial postures, such as 90-degree curved blades, the replacement of consumables requires multiple complex actions such as posture conversion, removal of old consumables, and adsorption and pasting of new consumables. The technical solution of this patent cannot cover such complex working conditions.

[0014] (3) The device lacks anti-sticking design during the loading process of consumables. When thin consumables such as sandpaper and scouring pad stick together due to static electricity or compression, it is difficult to ensure that only one consumable is loaded each time.

[0015] In summary, existing automated surface polishing equipment for parts still has significant technical shortcomings in terms of automated replacement of consumables, and further improvements are urgently needed. Summary of the Invention

[0016] To address the shortcomings of existing technologies, this invention provides an automated surface grinding workstation for parts, which automates the removal and loading of grinding consumables, solving the problems of low efficiency and poor consistency in manual operation, and improving the overall automation level and processing quality consistency of the grinding workstation. It is especially suitable for the mass automated grinding production of precision parts with extremely high surface quality requirements, such as semiconductor aluminum cavities.

[0017] To achieve the above objectives, the present invention provides the following technical solution:

[0018] An automatic surface grinding workstation for parts includes: a machine tool body; a loading and unloading platform, including a loading platform and an unloading platform located on one side of the machine tool body, wherein the loading and unloading platforms use an AGV transfer platform to transport parts; a grinding turntable located on the machine tool body; a dust removal device, including a dust suction pipe located on the machine tool body and corresponding to the grinding turntable, wherein the outer end of the dust suction pipe is equipped with a suction device; a tool magazine, including a tool head assembly, wherein multiple sets of grinding tools are installed on the tool head assembly, and one side of the tool head assembly is respectively provided with a rotary cutting consumable removal device, an automatic consumable loading device, and an integrated consumable replacement device corresponding to different grinding tools; the rotary cutting consumable removal device includes a vertical moving module, wherein the vertical moving module... A rotating bracket is mounted on the module, and a rotary cutting mechanism and a clamping scraping mechanism are mounted on the outer end of the rotating bracket; a corresponding positioning mechanism is provided around the rotary cutting mechanism; the automatic consumable loading device includes a consumable loading platform, on which a lifting consumable cylinder assembly is mounted, and consumables are installed inside the consumable cylinder assembly; a lifting component that extends into the lifting consumable cylinder assembly and has the function of lifting consumables is mounted on the upper consumable platform; the integrated consumable replacement device includes a consumable loading mechanism provided on the machine tool body, and the consumables in the consumable loading mechanism are adsorbed by a rotary adsorption mechanism; the rotary adsorption mechanism has a corresponding forward and backward moving mechanism to realize forward and backward movement; a rotating bracket is provided on one side of the grinding tool, and a rotary cutting mechanism is mounted on the rotating bracket.

[0019] Furthermore, the vertical moving module includes a module bracket, with upper and lower sliding rails on opposite sides of the module bracket, and a U-shaped sliding bracket slidably mounted on the upper and lower sliding rails, with a rotating bracket mounted on one side of the U-shaped sliding bracket; a vertical driving component is mounted on the lower part of the module bracket, and the vertical driving component is connected to the U-shaped sliding bracket.

[0020] Furthermore, the rotary cutting mechanism includes a rotary cylinder mounted on a rotary support, a rotary cutting frame connected to the rotary cylinder, a rotary cutting track on the outer side of the rotary cutting frame, a rotary cutting belt mounted on the rotary cutting track, and rotary cutting needles facing outwards mounted on the rotary cutting belt; a rotary cutting motor is installed inside the rotary cutting frame, and the rotary cutting motor is connected to the rotary cutting belt.

[0021] Furthermore, the scraping mechanism includes a scraping frame located on one side of the rotary cutting frame. An upper scraping cylinder and a lower scraping cylinder are mounted on the scraping frame. The upper scraping cylinder is connected to an upper scraping plate, and the lower scraping cylinder is connected to a lower scraping plate. The upper and lower scraping cylinders work together inward to achieve a joint scraping action of the upper and lower scraping plates.

[0022] Furthermore, the positioning mechanism includes a positioning plate, on which a positioning cylinder is mounted, and the positioning cylinder is drivenly connected to multiple positioning rods.

[0023] Furthermore, the lifting consumable cylinder assembly includes a consumable cylinder mounted on the upper consumable platform. Multiple lifting plates are symmetrically mounted on the outer surface of the consumable cylinder, and a consumable cylinder cylinder is drivenly connected to the lower end face of each lifting plate.

[0024] Furthermore, the lifting component includes a long lifting cylinder that extends through the lower end of the upper consumable platform and the consumable cylinder.

[0025] Furthermore, the consumable loading mechanism includes a consumable cylinder, and a long lifting cylinder is installed at the lower part of the consumable cylinder, the long lifting cylinder passing through the lower end of the consumable cylinder.

[0026] Furthermore, the rotary adsorption mechanism includes a rotary cylinder, which is drivenly connected to a rotary frame. A vacuum suction cup is installed at the outer end of the rotary frame, and the vacuum suction cup is connected to a vacuum generator through a pipeline.

[0027] Furthermore, the forward and backward moving mechanism includes a forward and backward moving cylinder, the piston rod of which is connected to the rotary cylinder, so that the rotary cylinder, the rotary frame and the vacuum suction cup fixed together with the rotary cylinder can move forward and backward together.

[0028] Compared with the prior art, the technology of the present invention has the following advantages:

[0029] 1. This invention achieves full automation of the entire process from loading and unloading parts to grinding and material replacement by coordinating the five-axis machine tool body with the automatic loading and unloading platform and AGV transfer platform, combined with the automated consumable management functions of the rotary cutting consumable removal device, automatic consumable loading device and consumable replacement integrated device in the tool magazine. This effectively reduces the degree of manual intervention and human operation error, and improves processing efficiency and surface quality consistency. It is especially suitable for the mass automated grinding production of precision parts with extremely high surface quality requirements, such as semiconductor aluminum cavities.

[0030] 2. This invention, by incorporating a rotary cutting device for removing consumables, utilizes a vertically moving module to drive the rotary cutting mechanism to rise and fall. The rotary cutting needle within the mechanism inserts into the gap between the consumable and the grinding tool and rotates downwards, efficiently and stably removing used consumables from the grinding tool. This rotary cutting insertion combined with rotation and pull-down method effectively overcomes the difficulty of consumables sticking tightly due to the significant pressure exerted during grinding, ensuring thorough removal without damaging the grinding tool surface, thus providing a reliable guarantee for the continuous operation of automated grinding.

[0031] 3. This invention includes a scraping mechanism on one side of the rotary cutting mechanism. After the rotary cutting needle tears off the consumable, the combined scraping action of the upper and lower scraping plates removes any residual consumable that may be stuck to the rotary cutting needle. This invention effectively solves this technical blind spot through the scraping mechanism, ensuring that the rotary cutting needle is not interfered with by residual consumable during the next operation, thus improving the stability of the equipment during long-term automated operation.

[0032] 4. This invention employs an automatic consumable loading device. A consumable cylinder lifts the consumable cylinder, allowing the floating head of the grinding tool to slide in along the conical surface at the top of the cylinder. Automatic centering is achieved through a purely mechanical, passive method. Then, a long lifting cylinder lifts the consumable upwards and adheres it to the bottom of the grinding tool, thus achieving automated consumable loading. This conical sliding centering method is simpler, lower in cost, and more reliable, while ensuring concentricity of the consumable adhesion, fundamentally avoiding uneven grinding caused by eccentric adhesion.

[0033] 5. This invention specifically addresses grinding tools with unique spatial orientations, such as 90-degree curved blades, by incorporating an integrated consumable replacement device. Through the coordinated action of a rotary cutting mechanism to remove the old consumable, a vacuum suction cup to pick up the new consumable, a rotary cylinder to adjust the consumable from a horizontal to a vertical orientation, and a forward and backward moving cylinder to push the consumable to the attachment position, the entire process of consumable replacement for tools with complex orientations is fully automated. Existing technologies do not address automated consumable replacement solutions for such uniquely oriented tools; this invention fills this technological gap and has a wider range of applications.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] This embodiment describes the overall structure of the equipment.

[0046] like Figure 1 As shown, the automatic surface grinding workstation of the present invention includes a machine tool body 2, a tool magazine 1, a loading and unloading platform, a grinding turntable 10, and a dust removal device.

[0047] The machine tool body 2 is made of castings or marble structure, which has good stability and vibration reduction performance, and can ensure the rigidity requirements of the equipment during the grinding process. The machine tool body 2 can be in the form of a five-axis machining center, specifically including a 3+2 fixed-axis five-axis or a five-axis linkage structure. Its spindle can be rotary table type, swivel head type, swivel-rotation composite type or gantry type, as long as it can provide macroscopic motion machining trajectory to realize the machining trajectory of the corresponding part.

[0048] The loading and unloading platform includes a loading platform 4 and an unloading platform 5 located on one side of the machine tool body 2. The loading platform 4 is used to place the parts 3 to be processed, and the unloading platform 5 is used to place the parts 3 that have been processed. Both the loading platform 4 and the unloading platform 5 cooperate with the AGV transfer platform 6. The AGV transfer platform 6 can automatically transport the parts 3 to be processed to the loading platform 4 and remove the parts 3 that have been processed and placed on the unloading platform 5, thereby realizing automated loading and unloading and material transfer.

[0049] The grinding rotary table 10 is mounted on the machine tool body 2 and is used to support the part 3 and drive the part 3 to rotate or swing during processing, so as to achieve multi-angle grinding processing in conjunction with the machine tool spindle. The rotary table motor 11 provides rotational power for the grinding rotary table 10.

[0050] The dust removal device includes a dust collection pipe mounted on the machine tool body 2 and corresponding to the grinding turntable 10, with a suction device at the outer end of the dust collection pipe. During the grinding process, the dust collection pipe can promptly remove the generated dust, ensuring a clean working environment. Preferably, the machine tool body 2 is a fully enclosed structure, and the device has a built-in dust concentration sensor that can alarm and shut down when the dust concentration exceeds the limit. All electrical components are explosion-proof and housed in an explosion-proof electrical box, and the equipment cables are sheathed in explosion-proof conduits to ensure the safety of equipment operation.

[0051] like Figure 1 As shown, the CNC system is located on one side of the machine tool body 2. It adopts a mature CNC system and has undergone secondary development. It controls the automated operation of the tool magazine through I / O and analog signal interaction. All electrical components are housed in the electrical box.

[0052] Example 2

[0053] Based on Example 1, the tool magazine structure is described in detail.

[0054] like Figure 2 and Figure 3 As shown, the tool magazine 1 includes a tool head assembly, on which multiple sets of grinding tools 7 are mounted. The tool head assembly can take different forms, such as disc type, hat type, chain type, or grid box type, and the specific form is selected based on the functional requirements.

[0055] On one side of the tool magazine 1, there are respectively a rotary cutting consumable removal device 8, an automatic consumable loading device, and an integrated consumable replacement device 9 for different grinding tools 7. The above three devices are used to realize the functions of removing old consumables from grinding tools, loading new consumables, and replacing consumables for special tools.

[0056] The grinding tool 7 uses a mechanical interface compatible with the machine tool spindle, such as standard interfaces like BT40, BT50, or HSK-A63. The tool has a standardized pneumatic and electrical interface; when the spindle locks the tool holder at the top, the pneumatic and electrical interface is simultaneously activated. Consumables, including sandpaper, scouring pads, sponge abrasive, and oil-soaked cotton, are attached to the surface of the grinding tool 7 using Velcro. The grinding tool 7 has a built-in sensor for real-time monitoring of the consumables' dynamic information, including wear and detachment. An alarm is triggered when the consumables reach the end of their lifespan or detach.

[0057] The grinding tool 7 has a floating characteristic, with a floating distance typically around 5mm, which can be adjusted according to process requirements. The tool tip has an eccentric characteristic; when placed in the tool magazine, its eccentric position is random, and the subsequent automatic consumable loading device needs to ensure that the consumables are adhered concentrically.

[0058] like Figure 4 and Figure 5 As shown, the rotary cutting consumable removal device 8 includes an up-and-down moving module, a rotating bracket is mounted on the up-and-down moving module, a rotary cutting mechanism and a clamping and scraping mechanism 80 are mounted on the outer end of the rotating bracket, and a corresponding positioning mechanism is provided around the rotary cutting mechanism.

[0059] The vertical moving module includes a module bracket 85, which is fixed to the machine tool body 2. Upper and lower sliding rails 84 are provided on opposite sides of the module bracket 85. A U-shaped sliding bracket 86 is slidably mounted on the upper and lower sliding rails 84, and a rotating bracket is mounted on one side of the U-shaped sliding bracket 86. A vertical driving component 83 is mounted at the lower part of the module bracket 85. The vertical driving component 83 is connected to the U-shaped sliding bracket 86 and drives the U-shaped sliding bracket 86 to slide vertically along the upper and lower sliding rails 84. The vertical driving component 83 can be a cylinder or a motor.

[0060] The rotary cutting mechanism includes a rotary cylinder 89 mounted on a rotary support, a rotary cutting frame 87 driven by the rotary cylinder 89, a rotary cutting track on the outer surface of the rotary cutting frame 87, a rotary cutting belt mounted on the rotary cutting track, and rotary cutting needles 88 facing outwards mounted on the rotary cutting belt. A rotary cutting motor is installed inside the rotary cutting frame 87, and the rotary cutting motor is driven by the rotary cutting belt to drive the rotary cutting belt to move, thereby driving the rotary cutting needles 88 to move along the rotary cutting track.

[0061] The scraping mechanism 80 includes a scraping frame located on one side of the rotary cutting frame 87. An upper scraping cylinder and a lower scraping cylinder are mounted on the scraping frame. The upper scraping cylinder is connected to an upper scraping plate, and the lower scraping cylinder is connected to a lower scraping plate. When the upper and lower scraping cylinders work together inward, they can achieve a joint scraping action, scraping off the consumables remaining on the rotary cutting needle 88.

[0062] The positioning mechanism includes a positioning plate 82, on which a positioning cylinder 81 is mounted. The positioning cylinder 81 is driven by multiple positioning rods. The positioning mechanism is used to precisely limit the height position of the grinding tool 7 before the consumable is removed.

[0063] The working process of the rotary cutting consumable removal device 8 is as follows:

[0064] The blade assembly rotates, rotating the grinding blade 7, from which the consumable to be removed, to the removal station; the positioning cylinder 81 in the positioning mechanism pushes the positioning rod to lift, precisely limiting the height of the grinding blade 7; the upper and lower drive components 83 drive the zigzag sliding bracket 86 to slide along the upper and lower slide rails 84 to the designated height position; the rotary cylinder 89 drives the rotary cutting frame 87 to rotate, causing the rotary cutting needle 88 to insert into the gap between the consumable and the grinding blade 7; the rotary cutting motor drives the rotary cutting belt to move, and the rotary cutting needle 88 rotates and pulls down, tearing the consumable from the grinding blade 7; the clamping and scraping mechanism 80 is activated, with the upper and lower clamping scrapers working together to scrape off any consumable that may be stuck on the rotary cutting needle 88; finally, all components are reset, completing the removal action.

[0065] like Figure 6 As shown, the automatic consumables feeding device includes a consumables feeding platform 14, on which a consumables lifting cylinder assembly is installed, and consumables are installed inside the consumables cylinder assembly. A lifting component is installed on the consumables feeding platform 14, which extends into the consumables lifting cylinder assembly for lifting the consumables.

[0066] The lifting consumable cylinder assembly includes a consumable cylinder 12 mounted on the upper consumable platform 14. Multiple lifting plates (not shown in the figure) are symmetrically mounted on the outer surface of the consumable cylinder 12. A consumable cylinder cylinder 13 is drivenly connected to the lower end face of each lifting plate. The consumable cylinder cylinder 13 is used to drive the consumable cylinder 12 to be lifted upward as a whole.

[0067] The upper end face of the consumable cartridge 12 is conical, used to cooperate with the floating head at the front end of the grinding tool 7 for centering. A brush is also fixed to the upper end of the consumable cartridge 12, which is used to bring back any excess sandpaper or other consumables when the cartridge 12 falls back, avoiding loading multiple sheets at once. The brush uses physical scraping action to bring the excess consumables back into the cartridge as it falls, effectively avoiding the problem of multiple sheets of thin consumables such as sandpaper and scouring pads sticking together due to static electricity or compression, thus ensuring that only one sheet of consumables adheres to the tool each time it is loaded. This avoids waste of consumables and ensures consistent grinding results.

[0068] The lifting component includes a long lifting cylinder 15, which passes through the lower end of the upper consumable platform 14 and the consumable cylinder 12, and is used to lift the consumables in the consumable cylinder 12 upward.

[0069] The working process of the automatic consumables dispensing device is as follows:

[0070] Under the machine tool program command, the grinding tool 7 returns to the zero point position of the tool head, which is the corresponding position of the automatic consumable loading device. The consumable cylinder cylinder 13 drives the consumable cylinder 12 to rise upwards, and the floating head at the front end of the grinding tool 7 slides into the consumable cylinder 12 along the conical surface at the upper end of the consumable cylinder 12, completing the centering of the eccentric floating head at the front end of the grinding tool 7; the long lifting cylinder 15 lifts upwards, lifting the consumable in the consumable cylinder 12 upwards and attaching it to the bottom of the grinding tool 7; after the attachment is completed, the long lifting cylinder 15 descends back to its original position, and the consumable cylinder cylinder 13 drives the consumable cylinder 12 to fall back; during the fall of the consumable cylinder 12, the brush at the upper end of the consumable cylinder 12 brings the excess consumable back into the consumable cylinder 12, ensuring that only one consumable is loaded at a time.

[0071] like Figure 7 As shown, the integrated consumable replacement device 9 is mainly used for replacing consumables for special grinding tools such as 90-degree curved tools. The device includes a consumable loading mechanism mounted on the machine tool body 2. The consumables in the loading mechanism are adsorbed by a rotary adsorption mechanism, which has a corresponding forward and backward moving mechanism to realize the forward and backward movement.

[0072] The consumable loading mechanism includes a consumable cylinder 12, and a long lifting cylinder 15 is installed at the lower part of the consumable cylinder 12. The long lifting cylinder 15 passes through the lower end of the consumable cylinder 12 and is used to lift the consumables in the consumable cylinder 12 upward.

[0073] The rotary adsorption mechanism includes a rotary cylinder 17, which is driven by a rotary frame. A vacuum suction cup 16 is installed on the outer end of the rotary frame, and the vacuum suction cup 16 is connected to a vacuum generator through a pipeline. The vacuum suction cup 16 is used to adsorb consumables lifted from the consumable loading mechanism.

[0074] The forward and backward movement mechanism includes a forward and backward movement cylinder 18. The piston rod of the forward and backward movement cylinder 18 is connected to a rotary cylinder 17, so that the rotary cylinder 17, the rotary frame fixed to the rotary cylinder 17 and the vacuum suction cup 16 move forward and backward together.

[0075] A rotary cutting mechanism is provided on one side of the integrated consumable replacement device 9, which is used to remove old consumables from the grinding tools. The rotary cutting mechanism has the same structure and working principle as the aforementioned rotary cutting consumable removal device, and will not be described again here.

[0076] The procedure for replacing the integrated consumable replacement device 9 is as follows:

[0077] The grinding tool (90-degree curved blade) rotates with the blade assembly, rotating the grinding tool to be replaced to the designated replacement station; the rotary cutting consumable removal device 8 activates, tearing off the old consumable from the curved blade. The long lifting cylinder 15 in the consumable loading mechanism lifts the consumable, while the vacuum suction cup 16 opens to hold the lifted consumable; after adsorption is complete, the long lifting cylinder 15 returns to its original position; the rotary cylinder 17 drives the rotary frame to rotate, adjusting the consumable from a horizontal to a vertical position. The forward and backward moving cylinder 18 pushes the rotary cylinder 17 and the vacuum suction cup 16 forward, attaching the consumable to the bottom of the grinding tool (90-degree curved blade), completing the consumable replacement.

[0078] Example 3

[0079] The processing procedure is as follows: Part 3 is positioned and installed on the grinding turntable 10 using a zero-point positioning system. The zero-point positioning system ensures that Part 3 has a uniform positioning reference during loading and unloading, reducing repeated clamping errors.

[0080] The workflow of the equipment is as follows: The AGV transfer platform 6 transports the part 3 to be processed to the loading platform 4; the part 3 enters the machine tool body 2 in a semi-automatic or fully automatic manner and is connected to the grinding turntable 10 through the zero-point positioning system; the grinding tools 7 in the tool magazine 1 are automatically called according to the processing program to grind the surface of the part 3; during the processing, the dust is promptly removed through the dust extraction pipe; after processing is completed, the part 3 is detached from the zero-point positioning system and exits to the unloading platform 5; the AGV transfer platform 6 transports the processed part 3 away.

[0081] During use, the grinding tool 7 automatically replaces consumables based on their wear condition: the old consumables are removed by the rotary cutting consumable removal device 8, and the new consumables are attached by the automatic consumable loading device 9; for special tools such as 90-degree curved tools, the consumables are replaced by the integrated consumable replacement device 9.

[0082] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
