Description

Technical Field

[0001] This invention relates to the field of casting product processing technology, specifically to a high-speed sawing machine. Background Technology

[0002] Casting, also known as (static) molding, involves injecting raw materials into a mold and allowing them to solidify to obtain a product similar to the mold cavity. Products removed after casting have venting channels, overflow outlets, runners, and sprues connected to the end of the runner—structures unrelated to the product's subsequent use. To separate the product from these structures for later processing, they need to be removed.

[0003] Currently, the removal of runners is mostly done by shearing. This involves setting up an upper and lower blade with opposite vertical positions. The lower blade is fixed to a product positioning component, while the upper blade is driven to move up and down by a drive component. In use, the product is placed horizontally on the positioning component for positioning, so that the runner to be removed is located on the lower blade. The drive component is then activated to drive the upper blade to move downwards, and the upper blade works in conjunction with the lower blade to shear and remove the runner.

[0004] However, the aforementioned existing technology is applicable to sprue cutting on a horizontal plane. For casting products with more complex spatial structures, which often have more three-dimensional sprues, such as those with attached... Figure 1 The product 100 shown is a car bracket currently manufactured by the applicant. When the product 100 is placed horizontally, its sprue 102 is located at one end of the product 100 in a ring shape, and the end face connecting the product 100 and the sprue 102 is an inclined surface. It is difficult to effectively cut the sprue 102 using existing technology. If it is forcibly cut, it is easy to cause the product 100 to deform.

[0005] In addition, the applicant produces attached Figure 1 When producing product 100 as shown, in order to meet the slag removal requirements and ensure the shrinkage requirements of porosity, an irregularly shaped space needs to be added to the end of the mold cavity connecting the gating 102, resulting in the end of the cast product 100 having the following characteristics. Figure 2 The remaining material 101 shown needs to be removed when cutting the gating 102.

[0006] In order to remove the excess material 101 from both the runner 102 and the end of the product 100 at the same time, the applicant attempted to use a band saw for cutting. However, due to the relatively low rigidity of the band saw and the high rigidity of the product 100, on the one hand, the band saw has a short service life and requires frequent shutdowns to replace it, resulting in reduced processing efficiency and increased processing costs; on the other hand, the band saw is prone to directional deviation due to the shape of the excess material 101 during the cutting process, resulting in excess material 101 remaining at the end of the product 100 after cutting, and the cut surface is uneven, affecting the quality of the product 100.

[0007] Therefore, there is an urgent need for a high-speed sawing machine to simultaneously remove excess material from the sprue and the product ends, ensuring that the cut product ends are free of excess material and have a smooth cut surface, thereby improving product quality. Summary of the Invention

[0008] The present invention aims to provide a high-speed sawing machine to solve the technical problem that after cutting and removing excess material from the sprue and the product end, there is residual material at the product end and the cut surface is uneven, resulting in a reduction in product quality.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A high-speed sawing machine includes a frame and a sawing mechanism mounted on the frame. The sawing mechanism includes a positioning component, a sawing component, and a drive component. The drive component drives the positioning component to move closer to or away from the sawing component. The positioning component includes a positioning bracket and a positioning mounting plate on top of the positioning bracket. The top of the positioning mounting plate is provided with a positioning block, a positioning pin, a support block, and a rotary clamping cylinder. The positioning pin is located on the side near the sprue. A clamping block is provided on the output shaft of the rotary clamping cylinder. The sawing component includes a sawing bracket and a sawing motor mounted on the sawing bracket. A circular saw blade is provided on the output shaft of the sawing motor. The circular saw blade is inclined, and the inclination angle of the circular saw blade is consistent with the inclination angle of the product end face.

[0011] The principles and beneficial effects of this solution:

[0012] In practical applications, the product to be cut is placed onto the positioning component manually or by a robotic arm, aligning the product's concave structure with the positioning block. The product is initially positioned under the guidance of the positioning block until the positioning pin is inserted into the corresponding hole, achieving precise positioning. At this point, the part of the product corresponding to the support block is supported, and the product is horizontal. The rotary clamping cylinder drives the clamping block to rotate above the product, then drives it downwards, pressing the product firmly onto the positioning mounting plate. Subsequently, the drive component moves the positioning component, along with the product to be cut, towards the sawing component. The sawing motor drives the circular saw blade to rotate, cutting away excess material, sprues, and stalks along the product's end. Then, the drive component moves the positioning component, along with the cut product, away from the sawing component until the positioning component resets. The rotary clamping cylinder then resets the clamping block, releasing the product from its fixed position on the positioning mounting plate. The cut product can then be removed manually or by a robotic arm.

[0013] 1. This solution uses a sawing motor to drive the circular saw blade to rotate, thereby cutting the scrap and runner. On the one hand, the circular saw blade has higher rigidity than the band saw. It is used to cut product scrap, runner, and stalk with high rigidity, which can ensure that the circular saw blade has a longer service life, thereby reducing the frequency of downtime to replace the circular saw blade, which is conducive to improving processing efficiency and reducing processing costs. On the other hand, the circular saw blade with higher rigidity combined with the rotary cutting method can effectively reduce or even avoid the circular saw blade deflecting in direction with the shape of the scrap during the cutting process, thereby ensuring the cutting effect of the scrap, reducing or even avoiding the residue of scrap at the end of the product, and ensuring a flat cut surface, which is conducive to improving product quality.

[0014] 2. In this solution, the circular saw blade is tilted, and the tilt angle of the circular saw blade is consistent with the tilt angle of the end of the product. During the process of the drive component driving the positioning component to move towards the sawing component, the circular saw blade can cut the excess material, sprue, and stalk along the end face of the product, thereby effectively removing the excess material, sprue, and stalk. Furthermore, the product is subjected to simple force during the entire cutting process, which can avoid product deformation and thus ensure product quality.

[0015] 3. This solution uses a drive component to move the positioning component carrying the product to be cut back and forth once in the direction of approaching and moving away from the sawing component, thereby achieving the cutting and removal of excess material, sprues, and material handles on the product. The whole process is fast and efficient. Furthermore, the rotary clamping cylinder drives the clamping block to press the product firmly onto the positioning mounting plate, replacing the traditional method of manually pressing the product. This not only effectively ensures the stability of the product's position during the cutting process to guarantee the cutting effect and thus product quality, but also significantly reduces the risk of accidents during the cutting operation.

[0016] 4. This solution first achieves initial positioning of the product by matching the positioning block with the product's concave structure. Under its own weight, the product slides downward along the positioning block. Guided by the positioning block, the product's hole aligns with the positioning pin, allowing the positioning pin to insert into the product's hole, thus achieving precise positioning. This solution gradually positions the product using positioning blocks and positioning pins, which reduces the positioning accuracy during product placement while ensuring the final positioning accuracy. This greatly reduces the difficulty of manual or robotic arm operation and helps improve processing efficiency.

[0017] 5. In this solution, the positioning pin is set on the side closest to the runner. Since the robotic arm transfers the product as a whole by gripping the material handle, the closer the distance between the positioning pin and the robotic arm is when the robotic arm places the product, the more conducive it is to the accurate placement of the product by the robotic arm. This ensures the final positioning accuracy of the product while further reducing the positioning accuracy during product placement and reducing the accuracy requirements of the robotic arm.

[0018] Preferably, as an improvement, the positioning bracket is provided with a sliding cylinder and a sliding guide. The output shaft of the sliding cylinder is fixedly connected to the positioning mounting plate. The sliding guide includes a sliding guide rail fixed on the positioning bracket and a sliding block fixed on the positioning mounting plate. The sliding block is slidably connected in the sliding guide rail, and the sliding direction of the sliding block is perpendicular to the driving direction of the driving component.

[0019] Beneficial Effects: This solution slides the positioning mounting plate onto the positioning bracket, with the sliding direction of the mounting plate perpendicular to the driving direction of the drive assembly. After the circular saw blade cuts the product, the sliding cylinder first drives the positioning mounting plate to slide closer to the drive assembly, moving the product away from the circular saw blade. The drive assembly then drives the positioning assembly to move away from the sawing assembly, resetting the product. This avoids contact and friction between the product and the circular saw blade during resetting, preventing damage to the product ends and ensuring product quality. The sliding cylinder-driven positioning mounting plate on the positioning bracket allows for precise control of its sliding speed and distance, ensuring the product effectively moves away from the circular saw blade. The sliding guide component guides the sliding of the positioning mounting plate on the positioning bracket, ensuring the product moves away from the circular saw blade in a direction perpendicular to the driving direction of the drive assembly, further preventing contact and wear between the product ends and the saw blade, thus further ensuring product quality.

[0020] Preferably, as an improvement, the positioning bracket is further provided with a mounting plate positioning component, which includes a positioning cylinder and a positioning plate. The output shaft of the positioning cylinder is provided with a positioning pin, the positioning plate is fixedly connected to the positioning mounting plate, and the positioning plate is provided with a positioning groove corresponding to the position of the positioning pin.

[0021] Beneficial effects: This solution uses a sliding cylinder to drive the positioning mounting plate to slide away from the drive assembly, aligning the end of the product to be cut with the circular saw blade. At this point, the positioning groove and the positioning pin are in the same position. The positioning cylinder drives the positioning pin to insert into the positioning groove, thus positioning the positioning mounting plate along its own sliding direction. This effectively prevents the positioning mounting plate from sliding relative to the positioning bracket during the cutting process of the circular saw blade, ensuring the positional stability of the product, improving the flatness of the cut end, and ultimately improving product quality.

[0022] Preferably, as an improvement, the sawing assembly further includes a saw blade cooling component, which includes a cooling block and a cooling air pipe connector and a cooling air nozzle disposed on the cooling block. A cooling air channel is provided inside the cooling block, and the cooling air pipe connector and the cooling air nozzle are both connected to the cooling air channel. The cooling air nozzle is positioned to align with the circular saw blade.

[0023] Beneficial effects: This solution introduces external cooling gas into the cooling air channel through the cooling air pipe joint, and then blows it onto the circular saw blade through the cooling air nozzle, realizing the air cooling treatment of the circular saw blade. This avoids the circular saw blade from overheating during continuous cutting, which could damage itself or even the product. It not only helps to extend the service life of the circular saw blade, but also effectively ensures product quality.

[0024] Preferably, as an improvement, the drive assembly includes a drive bracket and a drive motor mounted on the drive bracket. The output shaft of the drive motor is provided with a drive screw, and a drive block is threadedly connected to the drive screw. A drive plate is provided on the side of the drive block near the positioning assembly. The drive plate is fixedly connected to the positioning bracket, and the drive plate is slidably connected to the drive bracket along the drive direction. The positioning assembly is mounted on the drive plate.

[0025] Beneficial effects: This solution uses a drive motor to drive a lead screw to rotate, which in turn drives a drive block threadedly connected to the lead screw to move axially along the lead screw. This movement of the drive bracket along the lead screw axis leads to the movement of the positioning assembly along the lead screw axis, allowing the product on the positioning assembly to move closer to or further away from the circular saw blade, thus achieving product cutting and repositioning. This solution has a simple structure and reliable operation, facilitating installation and maintenance while ensuring effective cutting.

[0026] Preferably, as an improvement, it also includes a shank support assembly, which includes a support mounting base disposed on the frame, a support cylinder vertically mounted on the support mounting base, a shank support plate disposed on the output shaft of the support cylinder, and a shank positioning block disposed on the top of the shank support plate.

[0027] Beneficial Effects: This solution incorporates a material handle support component to support the material handle during product positioning. When the material handle is heavy, it ensures the product remains horizontal during positioning, preventing product rotation and securing it horizontally to the positioning mounting plate, thus guaranteeing subsequent cutting results. After product positioning and fixing, the positioning mounting plate slides away from the drive component under the drive of a sliding cylinder to align the product end with the circular saw blade. At this point, the support cylinder then drives the material handle support plate, along with the material handle positioning block, downwards, avoiding interference with the sliding of the positioning mounting plate and ensuring smooth cutting. Furthermore, this solution includes a material handle positioning block at the top of the material handle support plate, which positions the material handle during product positioning, improving positioning efficiency and effectiveness.

[0028] Preferably, as an improvement, it also includes a product inspection component, which includes an inspection mounting base disposed on a frame, an inspection mounting bracket disposed on the inspection mounting base, and a positioning sensor and a leveling sensor disposed on the inspection mounting bracket.

[0029] Beneficial effects: This solution incorporates a product detection component. A position sensor detects whether there is a product on the positioning component, and a leveling sensor detects whether the product on the positioning component is level. The detection signals from the position and leveling sensors can control the automatic and orderly operation of each component, effectively ensuring that the product is cut in a horizontal state. This guarantees the cutting effect and avoids potential damage to the circular saw blade and other structures that may occur when cutting the product at an angle, ensuring cutting safety and extending the service life of the entire sawing machine.

[0030] Preferably, as an improvement, it also includes a sawdust collection assembly, which includes a sawdust collection hopper, an opening baffle, and a baffle latch. The sawdust collection hopper is located below the sawing mechanism and has a structure with an open top and an opening on one side wall. The opening baffle is hinged to the frame at the opening on the side wall of the sawdust collection hopper, and the baffle latch is used to lock the opening baffle.

[0031] Beneficial effects: This solution uses a sawdust collection hopper located below the positioning component to collect sawdust generated during product cutting. After batch processing is completed, or after cutting has been ongoing for a period of time, the baffle lock can be opened to release the locking of the opening baffle, exposing the opening on the side wall of the sawdust collection hopper for cleaning. This solution has a simple structure and is easy to operate, preventing sawdust from falling directly into the working environment and contaminating it, thus ensuring a clean working environment and protecting the health of operators.

[0032] Preferably, as an improvement, it also includes an air blowing cleaning assembly, which includes an air blowing mounting base mounted on the frame, an air blowing mounting block on the air blowing mounting base, a cleaning air pipe connector and a cleaning air nozzle on the air blowing mounting block, an air blowing channel opened in the air blowing mounting block, and the cleaning air pipe connector and the cleaning air nozzle are both connected to the air blowing channel. The cleaning air nozzle is a deformable cleaning air nozzle.

[0033] Beneficial Effects: This solution incorporates an air-blowing cleaning component on the frame. Since the product's contact with the positioning component may cause debris to fall, and sawdust from the product may also splash onto the positioning component during cutting, the air-blowing cleaning component can be activated when a significant amount of debris and sawdust accumulates on the positioning component. The cleaning air connector introduces external air into the air blowing channel, which is then blown onto the positioning component through the cleaning air nozzle. This causes the accumulated debris and sawdust to fall into the collection hopper below, thus cleaning the positioning component. This solution features a simple structure, convenient operation, and a deformable cleaning air nozzle, allowing it to be aimed at various locations for effective air-blowing cleaning.

[0034] Preferably, as an improvement, the frame is provided with a shielding component for closing the frame. The shielding component has a discharge port at the position corresponding to the positioning component and a slag outlet at the position corresponding to the sawing component. A flexible baffle is provided at the slag outlet, and a slag outlet chute is connected to the slag outlet. A movable door component is provided at the discharge port. The movable door component includes a movable cylinder and a movable door plate disposed on the output shaft of the movable cylinder. The movable cylinder drives the movable door plate to move up and down to realize the opening and closing of the discharge port. The movable door component also includes a movable guide component. The movable guide component includes a guide plate disposed on the frame and a guide roller disposed on the movable door plate. The guide roller is rotatably connected in the guide groove formed by the guide plate and the bracket. A stop block is provided at the bottom of the guide plate.

[0035] Beneficial Effects: This solution incorporates a shielding component to enclose the machine frame, effectively blocking sawdust generated during cutting and reducing its dispersion into the external environment. This helps maintain a clean environment, reducing cleaning costs and protecting the health of operators. The shielding component features a material inlet and a slag outlet, facilitating the placement and removal of products to be cut and the efficient discharge of excess material, runners, and slag. A flexible baffle at the slag outlet not only allows for the discharge of excess material, runners, and slag but also provides some shielding at the slag outlet, further reducing sawdust dispersion into the external environment.

[0036] Furthermore, this solution incorporates a movable door assembly at the material feeding port. This assembly allows for the opening and closing of the feeding port. When placing products to be cut or retrieving cut products, the movable door assembly opens the feeding port. During the cutting process, the assembly also keeps the feeding port open, further reducing sawdust emissions into the environment. A moving guide component guides the vertical movement of the movable door panel, ensuring its positional stability during movement. The moving guide component in this solution has a simple structure, facilitating installation and maintenance. Attached Figure Description

A shielding component 11, an electrical control cabinet 12, and a control button component 13 are also mounted on the frame 1. The shielding component 11 is used to enclose the sawing mechanism, the air cleaning component 7, and the material handle support component 8 within the frame 1, preventing sawdust generated during cutting and sawdust flying during air cleaning from spreading into the air and polluting the working environment.

[0067] Combination Figure 10 and Figure 11 As shown, the drive assembly 3 includes a drive bracket 31 fixedly connected to the frame 1 by screws. One end of the drive bracket 31 is fixedly connected to a drive motor 32 by screws. A drive screw 33 is coaxially fixedly connected to the output shaft of the drive motor 32 via a coupling. In this embodiment, the drive motor 32 is a servo motor, and the drive screw 33 is a ball screw. A screw support seat 341 and a screw mounting seat 342 are fixedly connected to the drive bracket 31 by screws.

The drive plate 37 is also slidably connected to the frame 1 via the adapter plate 36, and the sliding direction of the drive plate 37 is the same as the driving direction of the drive assembly 3. Specifically, a slide rod 311 is fixedly connected to the frame 1 along the driving direction, and a slider 361 is fixedly connected to the adapter plate 36 at the position corresponding to the slide rod 311 by screws. The slider 361 has a groove at the position corresponding to the slide rod 311, and the slide rod 311 is slidably connected in the groove of the slider 361 to realize the sliding connection between the adapter plate 36 and the drive bracket 31, thereby realizing the sliding connection between the drive plate 37 and the drive bracket 31.

[0068] The surface of the drive bracket 31 is fixedly connected by screws as follows Figure 12 The drive motor protective cover 321 and drive protective cover 38 shown are for protecting the drive motor 32 and the drive assembly 38, respectively. The drive motor protective cover 321 protects the drive motor 32, while the drive protective cover 38 protects other structures of the drive assembly 3, reducing damage to the drive assembly 3 caused by sawdust. The bottom of the drive protective cover 38 has several through holes to allow small amounts of sawdust to fall out. Bellows covers 39 are provided on both sides of the drive plate 37. The bellows covers 39 can extend and retract with the movement of the drive plate 37, further enhancing the protective effect on top of the drive protective cover 38.

A positioning groove 454 is opened on the positioning plate 453 corresponding to the position of the positioning pin 452, and the width of the positioning groove 454 matches the diameter of the positioning pin 452. After the positioning mounting plate 42 slides to a position away from the drive component 3, the positioning groove 454 on the positioning plate 453 is aligned with the position of the positioning pin 452, and the positioning cylinder 451 drives the positioning pin 452 to insert into the positioning groove 454, thereby positioning the positioning mounting plate 42. To ensure that the positioning pin 452 moves axially, a guide block is fixedly connected to the positioning bracket 41 by screws. A through guide hole is opened on the guide block, and the positioning pin 452 slides axially within the guide hole.

[0072] like Figure 16 As shown, a positioning protective cover 46 is fixedly connected to the surface of the positioning bracket 41 by screws. The positioning protective cover 46 protects the rotary clamping cylinder 424, sliding cylinder 43, positioning cylinder 451 and other structures inside, reducing the damage caused by sawdust and extending the service life of the positioning component 4.

[0073] Combination Figure 17 and Figure 18 As shown, the sawing assembly 5 includes a sawing bracket 51 fixedly connected to the frame 1 by screws. A sawing motor 52 is fixedly connected to the side of the sawing bracket 51 near the positioning assembly 4 by screws.

The support mounting base 81 is fixedly connected to the material handle by screws as follows... Figure 23 The support cylinder protective cover 821 shown covers the support cylinder 82, protecting it and reducing damage to the support cylinder 82 from sawdust.

[0078] The operation method of a high-speed sawing machine includes the following steps:

[0079] S1. Open the discharge port 111: The moving cylinder 21 drives the cylinder connecting block 22 and the cylinder connecting plate 23 to move downward, thereby driving the moving door plate 24 to move downward. During the movement, the guide roller 251 rolls in the guide groove formed by the guide plate 252 and the frame 1 to guide the movement of the moving door plate 24 until the bottom of the moving door plate 24 abuts against the stop block 253. At this time, the discharge port 111 is opened.

[0080] S2. Product 100 Positioning: The robotic arm places the product 100 to be cut on the positioning bracket 41 through the feeding port 111, so that the inward recessed part of the product 100 corresponds to the position of the positioning block 421. Under the guidance of the positioning block 421, the product 100 slides down until the positioning pin 422 is inserted into the hole at the corresponding position of the product 100, thereby achieving the positioning of the product 100. At this time, the end of the product 100 away from the sprue 102 is supported on the support block 423, and the material handle 103 is supported on the material handle support plate 83. The material handle 103 is located between the two material handle positioning blocks 84, thus achieving the positioning of the product 100.

[0081] S3. Close the discharge port 111: The moving cylinder 21 drives the cylinder connecting block 22 and the cylinder connecting plate 23 to move upward, thereby driving the moving door plate 24 to move upward. During the movement, the guide roller 251 rolls in the guide groove formed by the guide plate 252 and the frame 1 to guide the movement of the moving door plate 24 until the top of the moving door plate 24 abuts against the top of the frame 1. At this time, the discharge port 111 is closed.

[0082] S4. Fixing Product 100: When the positioning sensor 63 detects that product 100 is placed on the positioning mounting plate 42, and the leveling sensor 64 detects that product 100 on the positioning mounting plate 42 is level, the rotary clamping cylinder 424 is started. First, it drives the clamping block 425 to rotate above product 100, and then drives the clamping block 425 to move downward until the clamping block 425 presses product 100 onto the positioning mounting plate 42, thereby fixing product 100.

[0083] S5. Cutting Preparation: After the product 100 is fixed, the support cylinder 82 drives the material handle support plate 83 to move downward, so that the height of the material handle support plate 83 is lower than the height of the positioning mounting plate 42, avoiding interference with the sliding of the positioning mounting plate 42; then the sliding cylinder 43 drives the positioning mounting plate 42 to slide away from the drive assembly 3, so that the end of the product 100 to be cut is aligned with the circular saw blade 53. At this time, the positioning groove 454 of the positioning plate 453 corresponds to the position of the positioning pin 452. The positioning cylinder 451 drives the positioning pin 452 to move closer to the positioning groove 454 until the positioning pin 452 is inserted into the positioning groove 454, thereby achieving the positioning of the positioning mounting plate 42 along its own sliding direction, thus ensuring the stability of the position of the product 100.

[0084] S6. Product 100 Cutting: Then start the drive motor 32, drive the drive screw 33 to rotate, thereby driving the positioning component 4 to move closer to the sawing component 5. The circular saw blade 53 cuts the scrap 101 and the sprue 102 along the end of the product 100, realizing the removal of the scrap 101, the sprue 102 and the material handle 103. The removed scrap 101, the sprue 102 and the material handle 103 slide out of the frame 1 from the slag outlet 112 along the slag outlet chute 114 and are collected and processed uniformly.

[0085] S7. Product 100 Reset: After cutting, the positioning cylinder 451 drives the positioning pin 452 to exit from the positioning groove 454, releasing the positioning of the positioning mounting plate 42; then the sliding cylinder 43 drives the positioning mounting plate 42 to move closer to the drive assembly 3, so that the product 100 is away from the circular saw blade 53; then the drive motor 32 drives the drive screw 33 to rotate in the opposite direction, thereby driving the positioning assembly 4 to move away from the sawing assembly 5, until the positioning assembly 4 is reset, and the product 100 is reset.

[0086] S8. Open the discharge port 111 again: The moving cylinder 21 drives the cylinder connecting block 22 and the cylinder connecting plate 23 to move downward, thereby driving the moving door plate 24 to move downward. During the movement, the guide roller 251 rolls in the guide groove formed by the guide plate 252 and the frame 1 to guide the movement of the moving door plate 24 until the bottom of the moving door plate 24 abuts against the stop block 253. At this time, the discharge port 111 is opened.

[0087] S9. Remove product 100: After product 100 is reset, the rotary clamping cylinder 424 drives the clamping block 425 to move upward to release the clamping of product 100, and drives the clamping block 425 to rotate and reset. At this time, the projection of the clamping block 425 on the horizontal plane does not coincide with that of product 100. The robotic arm takes out the cut product 100 through the feeding port 111 and transports it to the subsequent processing steps. The support cylinder 82 then drives the material handle support plate 83 to move upward and reset, so as to support the material handle 103 of the next product 100 to be cut.

[0088] Repeat steps S2-S9 above until all products in this batch 100 are processed, then close the discharge port 111.

[0089] S10. Cleaning sawdust: Start the air cleaning component 7, and introduce external air into the air blowing channel through the cleaning air pipe connector 73. Align the cleaning air nozzle 74 with the part of the positioning component 4 that needs to be cleaned, and then blow the air in the air blowing channel through the cleaning air nozzle 74 to the part to be cleaned, so as to blow the debris and sawdust accumulated on the positioning component 4 into the sawdust collection hopper 91 below, thereby realizing the air cleaning of the positioning component 4.

[0090] S11. Cleaning sawdust: Open the baffle lock 93 to release its lock on the vertical position of the opening baffle 92. Flip the opening baffle 92 downwards to expose the opening on the side wall of the sawdust collection hopper 91. The sawdust collected inside can be cleaned directly through the opening on the side wall of the sawdust collection hopper 91, or the entire sawdust collection hopper 91 can be removed for cleaning.
