Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a multifunctional deburring device for the inner and outer sides of a fork and its usage method. Background Technology

[0002] In the field of machining, especially in the manufacturing industries of automotive parts and construction machinery, the fork is a key connecting component, and its surface quality directly affects the assembly performance and service life of the product. During the machining process of the fork, such as casting, forging or machining, a large number of burrs are often generated on its inner and outer sides. These burrs not only affect the appearance quality of the product, but may also cause scratches, jamming or even damage to other precision parts during subsequent assembly. Therefore, deburring is an indispensable and important step in the production of forks. Traditional deburring methods rely heavily on manual labor using handheld grinding wheels, files, or brushes to process each burr individually. This approach is not only inefficient and labor-intensive but also struggles to guarantee consistency and precision, posing significant safety hazards. While semi-automatic and fully automatic deburring equipment has emerged with the development of automation technology, these devices are often limited in function, typically only capable of processing specific areas of the fork (e.g., the outer or inner side), and have a limited clamping capacity, making multi-station synchronous operation impossible. They also exhibit poor adaptability to complex structures or various burr types. Furthermore, existing equipment often lacks effective waste removal and protection measures during processing, easily causing environmental pollution and impacting operator health. Most equipment also lacks necessary safety features, posing operational risks. In summary, existing fork deburring equipment generally suffers from problems such as limited functionality, poor processing adaptability, low clamping efficiency, insufficient safety, and weak environmental friendliness.

[0003] Chinese patent discloses a special deburring device for fork machining (publication number: CN 114871776A), which includes a base plate and a quick-clamping mechanism. A slide rail is provided on the top right side of the base plate, and the quick-clamping mechanism is longitudinally slidably installed on the top of the slide table. However, this deburring device has a single function, low degree of automation, low clamping and processing efficiency, poor adaptability, insufficient safety protection, and lacks integrated waste disposal and environmental control measures. Therefore, there is a need for a multifunctional deburring device for the inner and outer sides of forks and its usage method. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of traditional deburring equipment for forks, which often suffer from limited functionality, low automation, low clamping and processing efficiency, poor adaptability, insufficient safety protection, and lack of integrated waste disposal and environmental control measures. Therefore, this invention proposes a multifunctional deburring equipment for the inner and outer sides of forks and its usage method.

The overall structural design integrates multiple functional modules into an L-shaped cabinet, resulting in a compact and fully functional design that facilitates production site layout and operation. Protective shields, side covers, and front / rear doors effectively protect internal precision components and reduce external interference and contamination. The water baffle opening and chip removal groove facilitate coolant flow and waste chip discharge during processing, keeping the work area clean. The combination of multi-layer clamping and an adjustable grinding wheel mechanism enables the equipment to efficiently deburr the inner and outer sides of the forks. An external deburring mechanism provides additional processing options, enhancing adaptability. Casters facilitate equipment movement and positioning, while a light-grate fence improves operational safety and prevents personnel from accidentally entering hazardous areas.

[0006] Preferably, the multi-layer clamping mechanism includes a multi-layer window plate corresponding to the opening of the water baffle. The multi-layer window plate has multiple clamping windows from top to bottom. A multi-layer clamping plate is provided on one side of the multi-layer window plate, and the multi-layer clamping plate has multiple square clamping positions for placing the forklift workpieces. Positioning guide rails are provided on both sides of the multi-layer clamping plate and are associated with the multi-layer window plate. By setting up the multi-layer window plate and clamping plate, layered and zoned clamping of multiple forklift workpieces is achieved, effectively utilizing the internal space of the equipment and increasing the number of workpieces processed in a single operation. The one-to-one correspondence between the clamping windows and clamping positions ensures that each workpiece accurately corresponds to the processing area, improving processing accuracy. The design of the positioning guide rails makes the clamping plate stable and its position adjustable, enhancing the adaptability and ease of operation of the clamping system.

[0007] Preferably, the top of the multi-layer clamping plate is provided with a clamping drive assembly; the clamping drive assembly includes a drive cylinder, the drive cylinder includes a piston cylinder and a piston rod associated with the piston cylinder, one end of the piston rod is provided with a pressure block, the pressure block is associated with the top of the multi-layer clamping plate; a connecting block is provided at the center of the top inner wall of the square clamping position, a positioning fixture is provided on one side of the connecting block, a limiting fixture is provided below the positioning fixture, and a forked workpiece is provided between the positioning fixture and the limiting fixture; multiple clamping windows on the multi-layer window plate are distributed at intervals along the vertical direction, and each clamping window is vertically corresponding to the corresponding square clamping position. The clamping drive assembly achieves rapid and stable workpiece clamping by using a cylinder-driven pressure block, preventing workpiece displacement or loosening during processing and ensuring processing quality and safety. The combined use of the positioning fixture and the limit fixture clamps the fork-shaped workpiece from both above and below, ensuring the workpiece's clamping strength and positioning accuracy. The vertical correspondence between the clamping window and the clamping position allows the machining tool to accurately act on the target area, avoiding mis-machining and improving processing efficiency and reliability. Preferably, the grinding wheel left-right adjustment mechanism includes a central movable plate, side support plates on both sides of the central movable plate, a central baffle plate on one side of the central movable plate, and multiple adjustable grinding wheel assemblies and an adjustment drive assembly for driving the adjustable grinding wheel assemblies to slide left and right on both sides of the central baffle plate; the adjustable grinding wheel assembly includes a spindle box, a drive spindle inside the spindle box, a clamping block connected to one end of the drive spindle, and an outer baffle brush connected to one end of the clamping block; the adjustment drive assembly includes a motor base, a grinding motor connected to one end of the motor base, the motor base cooperating with the side support plates, a motor synchronous pulley at one end of the grinding motor, multiple spindle synchronous pulleys at one end of the drive spindle with vertical synchronous belts spaced apart, and a transmission synchronous belt between the motor synchronous pulleys and the spindle synchronous pulleys; a belt baffle plate is provided on the top of both the motor synchronous pulleys and the spindle synchronous pulleys. This grinding wheel adjustment mechanism, through the combination of a central movable plate and a support plate, constructs a stable adjustment platform, ensuring the smoothness and accuracy of the grinding wheel assembly during operation. The adjustable grinding wheel assembly allows for flexible adjustment of the grinding wheel according to the inner and outer shapes and positions of the workpiece, enhancing its adaptability to complex surfaces. The synchronous belt pulley drive system achieves stable drive and precise control of the grinding wheel, improving the reliability of the machining process. The design of the central baffle and the pulley baffle effectively prevents machining fluid and debris from entering the drive components, extending the service life of the equipment. Multiple grinding wheel assemblies can work simultaneously or separately, improving machining efficiency and flexibility.

[0008] Preferably, the outer wall of the spindle box is provided with multiple adjusting handwheels on one side, a pointer is connected to one side of each handwheel, and a scale marking area is provided on one side of the pointer, the scale marking area cooperating with the outer wall of the spindle box. The combined use of the adjusting handwheels and scale markings allows the operator to intuitively and accurately adjust the grinding wheel position without relying on complex measuring tools, improving the ease of operation and positioning accuracy of the adjustment process. The design of the pointer and scale enhances the user-friendliness of the human-machine interface, helping to quickly meet the customized processing needs of different workpieces and improving the consistency and repeatability of processing.

[0009] Preferably, the external deburring mechanism includes an integrated cabinet, with a door on one side and a pull rod on the door. A lighting module is located on one side of the top of the cabinet body, and the lighting module includes a supporting frame plate. An LED light is located at the center of one side of the inner wall of the supporting frame plate. A brush deburring assembly is located on one side of the top surface of the cabinet body, and a grinding wheel deburring assembly is located on the other side. The brush deburring assembly and the grinding wheel deburring assembly are correspondingly arranged. A dust collection assembly is located on one side of the grinding wheel deburring assembly. The brush deburring assembly includes a brush drive motor, with one end of the brush drive motor penetrating through the inner wall of the cabinet body. The system includes a brush drive shaft, one end of which is connected to a grinding brush. A positioning mold plate is located at the bottom of the grinding brush, and a brush operating area is located on the outer side of the positioning mold plate. The deburring assembly includes a grinding wheel drive motor. One end of the grinding wheel drive motor penetrates the inner wall of the cabinet body and is connected to the grinding wheel drive shaft. One end of the grinding wheel drive shaft is connected to a grinding wheel. A workpiece placement platform is located at the bottom of the grinding wheel, and a grinding wheel operating area is located on the outer side of the workpiece placement platform. A protective cover is located on the outer side of the grinding wheel, and a foldable connecting rod is located on the edge of the protective cover. A stop is movably connected to one end of the foldable connecting rod. The external deburring mechanism provides an additional deburring method independent of the main processing area. By using two different deburring methods, brush and grinding wheel, it enhances the equipment's adaptability to different types of burrs and improves the overall processing flexibility. The lighting module improves the operator's field of vision and facilitates precise operation. The dust collection component effectively removes dust and debris generated during processing, keeping the working environment clean. The protective cover and foldable linkage structure enhance operational safety, preventing processing splashes from injuring the operator, while the stop design further improves the reliability of protection.

[0010] Preferably, the dust collection assembly includes an L-shaped suction port, one bottom end of which is connected to a suction pipe, and the bottom end of the suction pipe is connected to a dust collection box. The dust collection box has a hollow structure and a dust collection frame at its bottom. Through the L-shaped suction port and the piping system, the dust collection assembly achieves efficient collection of dust and debris from the processing area, preventing them from spreading outside the equipment or affecting processing quality. The layered design of the dust collection box and dust collection frame facilitates centralized storage and regular cleaning of waste, maintaining the cleanliness of the equipment's interior and surrounding environment, and contributing to improved hygiene and safety of the overall processing environment.

[0011] Preferably, the lifting mechanism includes a central lead screw, around which multiple column guide rods are provided. Both the central lead screw and the column guide rods are associated with a central movable plate. The multiple column guide rods share a common upper column plate at their tops and a common lower column plate at their bottoms. One end of the central lead screw passes through the upper column plate and is connected to a servo motor, while its bottom end is associated with the lower column plate. Through the combination of the lead screw and guide rods, the lifting mechanism achieves precise and stable vertical movement of the grinding wheel assembly, ensuring that the grinding wheel can accurately reach different height machining surfaces on the inner and outer sides of the workpiece. The servo motor drive provides high-precision control, improving the controllability and consistency of the machining process. The column guide rods enhance the stability of the lifting process, preventing deviation or shaking, and ensuring machining quality and equipment safety.

[0012] Preferably, the grating-sensor safety fence includes a rectangular frame structure made of metal. The frame has multiple transparent panels with handles. A grating receiver and a grating transmitter are located on opposite sides of the frame. The grating-sensor safety fence provides both physical and sensory protection between operators and the processing area. When personnel enter the hazardous area, the system can immediately detect and trigger the safety protection mechanism, effectively preventing accidents caused by misoperation or accidental approach during processing. The transparent panels do not obstruct the operator's field of vision, while enhancing the openness and visibility of the equipment. The handles facilitate the movement and adjustment of the fence, improving the overall user experience and safety.

[0013] Preferred: Step 1: Workpiece clamping and fixing During operation, the operator or the feeding device places the segmented fork workpieces into the square clamping positions of the multi-layer clamping plate in sequence. Each clamping position is equipped with a connecting block. The positioning fixture can be adjusted in position by the connecting block and cooperates with the limiting fixture below. The limiting fixture is designed to be replaceable according to different sizes of segmented fork workpieces to accommodate various specifications of workpieces. A certain floating gap is maintained between the positioning fixture and the limiting fixture. The operator sets the positioning fixture and the limiting fixture on the upper and lower sides of the workpiece manually or automatically and they work together to clamp and position the segmented fork workpiece from both the upper and lower or inner and outer directions to ensure that the segmented fork maintains a fixed posture in the clamping position and prevents displacement during processing. Subsequently, the multi-layer clamping plate, which holds the fork-shaped workpieces, is connected to the multi-layer window plate on the back of the main frame via positioning guides on both sides. This achieves precise vertical positioning and stable guidance of the clamping plate, ensuring that each clamping position and the corresponding clamping window on the multi-layer window plate are precisely aligned vertically, providing an accurate positioning basis for subsequent processing. After the clamping plate completes the loading and positioning of the workpieces, the drive assembly located at the top of the multi-layer clamping plate begins to operate. The cylinder in this drive assembly pushes the piston rod downward under air pressure. The pressure block at the end of the piston rod contacts the top of the multi-layer clamping plate and applies downward pressure, thereby synchronously clamping and fixing the entire clamping plate and all the fork-shaped workpieces on it. During this process, the connecting block moves downward with the clamping plate, and the positioning fixture and the limiting fixture cooperate to clamp the workpieces. Step 2: Grinding wheel drive and main deburring process After clamping, the equipment begins to perform the main deburring process. This process is mainly completed by the adjustable grinding wheel assembly controlled by the grinding wheel left and right adjustment mechanism and the lifting mechanism connected to it. The core power of the entire mechanism comes from the grinding motor mounted on the motor base. The grinding motor outputs rotational power through the motor synchronous pulley. The motor synchronous pulley is connected to multiple main shaft synchronous pulleys set on the drive main shaft through the transmission synchronous belt. The main shaft synchronous pulleys are arranged at intervals and cooperate with the vertical synchronous belt. When the grinding motor starts, the power passes through the motor synchronous pulley, the transmission synchronous belt, and the main shaft synchronous pulley in sequence, and is finally transmitted to the drive main shaft, which drives the clamping block connected to the drive main shaft and the outer bristle brush on the clamping block to rotate at high speed, so as to achieve the deburring and cleaning operation on the surface of the fork. To accommodate the machining position requirements of different fork sections, this mechanism features an adjustable grinding wheel assembly that can slide left and right. This assembly is mounted on a central movable plate. The left and right positions of the grinding wheel assembly are adjusted via a handwheel on the outer wall of the spindle box: when the operator turns the handwheel counterclockwise, the internal transmission structure drives the spindle to move to the left, thus shifting the grinding wheel assembly to the left; when the handwheel is turned clockwise, the internal transmission structure drives the spindle to move to the right, thus shifting the grinding wheel assembly to the right. During adjustment, a pointer and scale marking area on the outer wall of the spindle box provide intuitive position feedback to the operator, helping to accurately determine the current position of the grinding wheel. An adjusting bolt is located on one side of the scale marking area 8. This adjusting bolt secures the drive spindle. Loosening the bolt allows adjustment of the brush's forward and backward position; after adjustment, tightening the bolt secures the brush. In the vertical direction, the lifting and lowering of the grinding wheel assembly is controlled by a lifting mechanism, which includes: a central lead screw, multiple column guide rods around the perimeter, a top column plate and a bottom column base plate. The top of the lead screw is connected to a servo motor via a coupling. The servo motor drives the central lead screw to rotate, which in turn drives the intermediate movable plate that cooperates with the lead screw to move precisely up and down along the column guide rods, thereby enabling the entire grinding wheel assembly to adjust its position in the height direction to adapt to the machining surfaces of different heights of the fork. Step 3: Deburring using an external deburring mechanism. For special areas that are difficult to reach by the main grinding wheel, or for areas requiring different processing methods, such as brushing rather than grinding to remove burrs, the equipment is also equipped with an external deburring mechanism independent of the main processing area. This mechanism is an integrated cabinet with a lighting module on the top. The lighting module includes a support frame plate and LED lights to provide good visibility for operation. The cabinet also has a brush deburring component and a grinding wheel deburring component arranged side by side, which are used to remove stubborn or special-shaped burrs in different ways. The brush deburring assembly includes a brush drive motor, whose output is connected to a grinding brush via a brush drive shaft. Below the grinding brush is a positioning mold plate, on which the workpiece can be placed for brushing and cleaning. The abrasive wheel deburring assembly includes an abrasive wheel drive motor, whose output is connected to a grinding wheel via a grinding wheel drive shaft. Below the abrasive wheel is a workpiece placement platform for placing forks or localized areas requiring secondary processing. The abrasive wheel is also equipped with a protective cover on its outer side and is connected to a stop block via a foldable connecting rod to further enhance operational safety and prevent abrasive wheel splashing or accidental contact. In addition, the external mechanism is also equipped with a dust collection component, including an L-shaped dust collection port, a dust collection pipe connected to it, and a dust collection box. The bottom of the dust collection box is equipped with a dust collection frame to collect the dust and waste generated during the processing and keep the working environment clean. Step 4: Safety Protection and Equipment Relocation Throughout the processing, to ensure the personal safety of operators, a grating-sensor safety fence is installed outside the equipment. This fence is a rectangular metal frame structure, with grating transmitters and receivers installed on opposite sides to monitor in real time whether personnel enter the hazardous processing area. The fence frame is also equipped with multiple transparent panels and handles, which do not obstruct observation and facilitate operation and maintenance. Once the grating system detects personnel intrusion, the equipment can immediately trigger a shutdown protection to prevent accidental injuries during processing. In addition, the equipment is equipped with casters at the four corners of the bottom, giving the entire equipment good mobility and allowing for quick adjustment of the equipment position according to the actual layout needs of the production site.

[0014] The advantages of this invention are: This invention provides a multi-functional deburring device for the inner and outer sides of forks. Through an integrated L-shaped functional cabinet design, it organically integrates multiple functional modules, including a multi-layer clamping system, an adjustable grinding wheel processing mechanism, an external auxiliary deburring unit, a safety protection system, and a waste chip removal and dust collection device, into a single equipment architecture, significantly improving equipment integration and space utilization. The device employs a multi-layer clamping mechanism, capable of simultaneously clamping multiple fork workpieces. The workpieces are securely held by cylinder-driven pressure blocks and upper and lower positioning fixtures, increasing the number of parts processed at once and ensuring the positioning accuracy and stability of the workpieces during processing, avoiding processing deviations or safety accidents caused by insecure clamping. The combined application of the grinding wheel left-right adjustment mechanism and the lifting mechanism allows for precise position adjustment of the grinding wheel in both horizontal and vertical directions. With multiple sets of adjustable grinding wheel components, it can flexibly meet the deburring needs at different positions and angles on the inner and outer sides of the forks, improving processing adaptability and accuracy. Simultaneously, the synchronous belt pulley drive ensures the stability of the grinding wheel rotation and the reliability of power transmission. In addition, the equipment is equipped with an independent external deburring mechanism, which provides supplementary processing methods for different types or special parts of burrs through two different deburring methods: brushes and grinding wheels. This further enhances the equipment's adaptability to diverse processing needs. This external mechanism also integrates lighting, dust collection, and protective functions, optimizing the operating environment and safety. The omnidirectional wheels at the bottom of the equipment provide excellent mobility, allowing for quick adaptation to different production line layouts. The grating-sensor safety fence, through non-contact photoelectric detection, effectively prevents operators from accidentally entering dangerous areas during processing, significantly improving the safety level of equipment operation. Overall, through its modular and multi-functional structural design, this equipment not only achieves efficient and precise removal of burrs from the inner and outer sides of workpieces, but also demonstrates significant functional advantages in terms of operational safety, processing adaptability, environmental friendliness, and equipment mobility. It can meet the comprehensive needs of modern manufacturing for high-efficiency, high-precision, and high-safety deburring processing. Attached Figure Description

[0038] In this embodiment, the grating-sensor safety fence includes a rectangular frame structure made of metal, a fence frame 10, and multiple transparent panels 9. Each transparent panel 9 has a handle 8. A grating receiver 7 and a grating transmitter 11 are respectively located on opposite sides of the fence frame 10. The grating-sensor safety fence establishes both physical and sensory protection between operators and the processing area. When personnel enter the hazardous area, the system can immediately detect and trigger the safety protection mechanism, effectively preventing safety accidents caused by misoperation or accidental approach during processing. The transparent panels 9 do not obstruct the operator's field of vision, while enhancing the openness and visibility of the equipment. The handles 8 facilitate the movement and adjustment of the fence, improving the overall user experience and safety.

[0039] In this embodiment: Step 1: Workpiece clamping and fixing During operation, the operator or the feeding device places the segmented fork workpiece 31 into the square clamping position 27 of the multi-layer clamping plate 26 in sequence. Each clamping position is equipped with a connecting block. The positioning fixture 30 can be adjusted in position by the connecting block and cooperates with the limiting fixture 32 below. The limiting fixture 32 is designed to be replaceable according to the size of different segmented fork workpieces 31 to adapt to various specifications of workpieces. A certain floating gap is maintained between the positioning fixture 30 and the limiting fixture 32. The operator sets the positioning fixture 30 and the limiting fixture 32 on the upper and lower sides of the workpiece manually or automatically and they work together to clamp and position the segmented fork workpiece 31 from both the upper and lower or inner and outer directions to ensure that the segmented fork maintains a fixed posture in the clamping position and prevents displacement during processing. Subsequently, the multi-layer clamping plate 26, which clamps the fork workpiece 31, is connected to the multi-layer window plate 28 on the back of the main frame via positioning guide rails 25 on both sides. This achieves precise vertical positioning and stable guidance of the clamping plate, ensuring that each clamping position and the corresponding clamping window 29 on the multi-layer window plate 28 are precisely aligned vertically, providing an accurate positioning basis for subsequent processing. After the clamping plate completes the loading and positioning of the workpiece, the drive assembly located at the top of the multi-layer clamping plate 26 begins to work. The cylinder in the drive assembly pushes the piston rod 23 downward under air pressure. The pressure block 24 at the end of the piston rod 23 contacts the top of the multi-layer clamping plate 26 and applies downward pressure, thereby synchronously clamping and fixing the entire clamping plate and all the fork workpieces 31 on it. During this process, the connecting block moves downward with the clamping plate, and the positioning fixture 30 and the limiting fixture 32 cooperate to clamp the workpiece. Step 2: Grinding wheel drive and main deburring process After clamping, the equipment begins to perform the main deburring process. This process is mainly completed by the adjustable grinding wheel assembly controlled by the grinding wheel left and right adjustment mechanism and the lifting mechanism connected to it. The core power of the entire mechanism comes from the grinding motor 49 mounted on the motor base 45. The grinding motor 49 outputs rotational power through the motor synchronous pulley 44. The motor synchronous pulley 44 is connected to multiple main shaft synchronous pulleys 47 set on the drive main shaft 39 through the transmission synchronous belt 46. The main shaft synchronous pulleys 47 are arranged at intervals and cooperate with the vertical synchronous belt 48. When the grinding motor 49 starts, the power passes through the motor synchronous pulley 44, the transmission synchronous belt 46, and the main shaft synchronous pulleys 47 in sequence, and is finally transmitted to the drive main shaft 39, which drives the clamping block 38 connected to the drive main shaft 39 and the outer bristle brush 37 on the clamping block 38 to rotate at high speed, so as to achieve the deburring and cleaning operation on the surface of the fork. To accommodate the processing position requirements of different fork sections, this mechanism is equipped with an adjustable grinding wheel assembly that can slide left and right. This assembly is mounted on the central movable plate 33. The left and right positions of the grinding wheel assembly are adjusted via an adjusting handwheel 42 on the outer wall of the spindle box 36. When the operator turns the adjusting handwheel 42 counterclockwise, the internal transmission structure drives the spindle to move to the left, thus shifting the grinding wheel assembly to the left. When the operator turns the adjusting handwheel 42 clockwise, the internal transmission structure drives the spindle to move to the right, thus shifting the grinding wheel assembly to the right. During adjustment, the pointer 41 and the scale marking area 40 on the outer wall of the spindle box 36 provide intuitive position feedback to the operator, helping to accurately grasp the current position of the grinding wheel. An adjusting bolt is located on one side of the scale marking area 408. This adjusting bolt is used to fix the drive spindle 39. Loosening the bolt allows adjustment of the brush's front and back position; after adjustment, tightening the bolt secures the brush. In the vertical direction, the lifting and lowering of the grinding wheel assembly is controlled by a lifting mechanism, which includes: a central lead screw 18, multiple column guide rods 17 around the perimeter, a top column plate 4 and a bottom column base plate 20. The top of the lead screw is connected to a servo motor 16 via a coupling. The servo motor 16 drives the central lead screw 18 to rotate, which drives the intermediate movable plate 33 that cooperates with the lead screw to move up and down precisely along the column guide rods 17, thereby driving the entire grinding wheel assembly to achieve position adjustment in the height direction to adapt to the machining surface of the fork at different heights. Step 3: Deburring using an external deburring mechanism. For special areas that are difficult to reach by the main grinding wheel, or for areas requiring different processing methods, such as brushing rather than grinding to remove burrs, the equipment is also equipped with an external deburring mechanism independent of the main processing area. This mechanism is an integrated cabinet 5, with a lighting module on the top of the cabinet. The lighting module includes a support frame plate 50 and an LED light 71, providing good visibility for operation. The cabinet also has a brush deburring component and a grinding wheel deburring component arranged side by side, which are used to remove stubborn or special-shaped burrs in different ways. The brush deburring assembly includes a brush drive motor 65, whose output is connected to a grinding brush 58 via a brush drive shaft 64. Below the grinding brush 58 is a positioning mold plate 57, on which the workpiece can be placed for brushing and cleaning. The abrasive wheel deburring assembly includes an abrasive wheel drive motor 67, whose output is connected to a grinding abrasive wheel 60 via a grinding wheel drive shaft 66. Below the abrasive wheel is a workpiece placement table 52, used to place the fork or localized areas that require secondary processing. The outer side of the abrasive wheel is also equipped with a protective cover 61, which is connected to a stop block 63 via a foldable connecting rod 62 to further improve operational safety and prevent abrasive wheel splashing or accidental contact. In addition, the external mechanism is also equipped with a dust collection component, including an L-shaped dust collection port 59, a dust collection pipe 68 connected thereto, and a dust collection box 69. The bottom of the dust collection box 69 is equipped with a dust collection frame 70, which is used to collect dust and waste generated during the processing and keep the working environment clean. Step 4: Safety Protection and Equipment Relocation Throughout the processing, to ensure the personal safety of operators, a grating-sensor safety fence is installed outside the equipment. This fence is a rectangular frame structure made of metal, with a grating transmitter 11 and a grating receiver 7 installed on opposite sides to monitor in real time whether personnel enter the dangerous processing area. The fence frame 10 is also equipped with multiple transparent panels 9 and handles 8, which do not obstruct observation and facilitate operation and maintenance. Once the grating system detects personnel intrusion, the equipment can immediately trigger a shutdown protection to prevent accidental injury during processing. In addition, the equipment is equipped with casters 6 at the four corners of the bottom, giving the entire equipment good mobility and allowing the equipment position to be quickly adjusted according to the actual layout needs of the production site.
