Description

Technical Field

[0001] This invention relates to the field of milling equipment technology, specifically to a horizontal milling machine tool and its processing method. Background Technology

[0002] A horizontal milling machine is a type of mechanical equipment used for metal cutting. Its spindle axis is parallel to the worktable surface, enabling it to accurately complete the milling of various complex contours of workpieces, such as planes and grooves.

[0003] Nowadays, when using a horizontal milling machine, the workpiece is first fixed on the worktable using a fixture. Then, the multi-axis motion system on the spindle controls the milling cutter to change its position, and the multi-axis motion system on the worktable controls the movement of the worktable to change its position, so that the milling cutter can perform milling operations corresponding to the machining area of ​​the workpiece. After machining, a large amount of metal shavings will accumulate on the surface of the worktable and in the T-slot. At this time, the operator will use cleaning tools to clean the metal shavings on the worktable to prepare for the next workpiece machining.

[0004] In existing cleaning processes, workers typically clean the worktable manually with hand tools. First, they scrape out debris from the T-slots, then use a cleaning brush to sweep away debris from the table surface and slots, and finally use an air gun or water spray gun to complete the final cleaning. However, this method has several drawbacks: firstly, manually cleaning the worktable increases the worker's workload; secondly, workers usually clean several T-slots one by one, leading to low cleaning efficiency; to improve efficiency, the contact area between the hand tools and the worktable needs to be increased so that the cleaning tool can contact several T-slots and the worktable surface simultaneously. Increasing the contact area results in a larger cleaning tool, which not only increases worker fatigue during handling but also increases friction, further increasing the worker's workload. Therefore, this invention proposes a horizontal milling machine tool and its processing method to effectively solve the above-mentioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide a horizontal milling machine tool and its machining method to solve the problems mentioned in the background art.

[0006] The present invention is achieved through the following technical solution: a horizontal milling machine tool, including a machine body and a worktable disposed on the machine body, wherein a plurality of parallel T-slots are provided on the worktable, and a movable compartment capable of reciprocating along the length of the worktable is also provided, and the movable compartment is also capable of moving vertically, and a cleaning mechanism for cleaning the worktable and the T-slots is provided on the movable compartment. The cleaning mechanism includes several cleaning sections disposed on the side of the mobile compartment facing the workbench. The cleaning sections and the T-slots are arranged in a one-to-one correspondence. Each cleaning section includes a fixed cleaning block and a movable cleaning block. The fixed cleaning block is fixedly disposed on the mobile compartment, and the number of the movable cleaning block is at least one and it is slidably disposed on the mobile compartment along the width direction of the workbench. There is a gap between two adjacent fixed cleaning blocks, and the movable cleaning block can slide along the width of the workbench to fill the gap; When the movable compartment moves from the first side to the second side of the workbench, the movable cleaning block slides to fill the gap between adjacent fixed cleaning blocks. Several fixed cleaning blocks and several movable cleaning blocks are spliced ​​together to form a straight cleaning structure that matches the width of the workbench, so as to scrape off metal debris from the top surface of the workbench. When the movable compartment moves from the second side to the first side of the workbench, the movable cleaning block slides back to its original position to combine with the fixed cleaning block to form a T-shaped cleaning structure, and the T-shaped cleaning structure moves vertically downward into the T-shaped groove to clean the metal debris in the T-shaped groove.

[0007] Optionally, a linear slide is provided on the side of the workbench along its length. The linear slide has a slide base, and a cylinder is fixedly mounted on the slide base along the height direction of the workbench. The movable end of the cylinder is fixedly connected to the movable compartment and can drive the movable compartment to move vertically up and down.

[0008] Optionally, the shape of the fixed cleaning block is adapted to the shape of the T-groove, and the number of movable cleaning blocks in each cleaning section is two. The two movable cleaning blocks are slidably disposed on the moving chamber along the width direction of the workbench. When two movable cleaning blocks move away from each other until the distance between them is equal to the width of the fixed cleaning block, the movable cleaning blocks and the fixed cleaning block are staggered and the facing surfaces of the movable cleaning blocks in two adjacent cleaning sections are in a close-fitting state; when two movable cleaning blocks move closer to each other until they are in a close-fitting state, the two movable cleaning blocks combine to form a cleaning structure with the same shape as the fixed cleaning block and are aligned and distributed with the fixed cleaning block.

[0009] Optionally, the top of the movable cleaning block extends into the moving compartment and is connected to a drive mechanism, which is used to control the two movable cleaning blocks in each cleaning section to move closer or further apart from each other; The driving mechanism includes a first iron plate and a second iron plate fixedly connected to the tops of two movable cleaning blocks, respectively. The first iron plate and the second iron plate are symmetrically distributed in the width direction of the workbench, and a movable cavity is formed between the first iron plate and the second iron plate. An electromagnet is fixedly installed in the movable cavity. The electromagnet has two magnetic ends, which face the first iron plate and the second iron plate respectively. Springs are provided between the electromagnet and the first iron plate and between the electromagnet and the second iron plate. The springs are distributed along the width direction of the workbench and their two ends abut against the electromagnet and the facing surfaces of the first iron plate and the second iron plate respectively. In the natural state, the springs are in a compressed state.

[0010] Optionally, a first connecting plate is fixedly connected to the same side of several first iron plates, and a second connecting plate is fixedly connected to the side of several second iron plates away from the first connecting plate; the first connecting plate is used to drive several first iron plates to move synchronously, and the second connecting plate is used to drive several second iron plates to move synchronously.

[0011] Optionally, both the fixed cleaning block and the movable cleaning block have an internal hollow structure. A partition plate is fixedly provided in the inner cavity of the fixed cleaning block, which divides the inner cavity of the fixed cleaning block into a first chamber and a second chamber. The first chamber is located on the side closer to the movable cleaning block, and the second chamber is located on the side farther away from the movable cleaning block. Air blowing holes are provided on the first chamber, the second chamber, and the movable cleaning block for blowing air onto the workbench surface or the T-slot.

[0012] Optionally, the air vent on the first chamber is located on the side facing the movable cleaning block, the air vent on the second chamber is located on the side away from the movable cleaning block, and the air vent on the movable cleaning block is located on the side away from the fixed cleaning block. The movable chamber is equipped with an air guiding mechanism. When the cleaning unit cleans the workbench surface, the air guiding mechanism is used to control the gas flow in the movable chamber to the first chamber and the movable cleaning block. When the cleaning unit cleans the T-shaped groove, the air guiding mechanism is used to control the gas flow in the movable chamber to the second chamber.

[0013] Optionally, the bottom wall of the mobile compartment is provided with a first air inlet, a second air inlet, and a third air inlet. The first air inlet is connected to a first chamber, the second air inlet is connected to a second chamber, and the third air inlet is connected to a movable cleaning block. The air guiding mechanism is used to control the opening and closing of the air inlets.

[0014] Optionally, the air guiding mechanism includes a first sealing plate and a second sealing plate fixedly disposed on the side of the first connecting plate opposite to the second connecting plate, and also includes a third sealing plate fixedly disposed on the side of the second connecting plate opposite to the first connecting plate. When the cleaning unit cleans the workbench surface, the first sealing plate and the first air inlet are misaligned, the second sealing plate and the second air inlet are aligned, and the third sealing plate and the third air inlet are misaligned. When the cleaning unit cleans the T-shaped groove, the first sealing plate and the first air inlet are aligned, the second sealing plate and the second air inlet are misaligned, and the third sealing plate and the third air inlet are aligned.

[0015] The present invention also proposes a processing method applicable to the above-mentioned horizontal milling machine tool, comprising the following steps: S1: Fix the workpiece to be processed on the worktable by means of the fixture and T-slot, so that the workpiece processing area corresponds to the position of the machine tool milling cutter; S2: Start the machine tool and allow the milling cutter to process the workpiece at different speeds, feed rates, and milling depths; S3: After machining is completed, disassemble the fixture and remove the workpiece so that the fixture and workpiece are no longer placed on the worktable. S4: Control the filling of the gap between adjacent fixed cleaning blocks, then drive the moving chamber to lower the cleaning unit so that the bottom surfaces of both the fixed and movable cleaning blocks are in contact with the workbench surface. Then control the moving chamber to move from the first side to the second side of the workbench to complete the cleaning of metal debris on the workbench surface. S5: Control the two movable cleaning blocks in each cleaning section to move closer to each other and combine with the fixed cleaning block to form a T-shaped cleaning structure that matches the shape of the T-slot. Drive the moving chamber to descend so that the cleaning section and the T-slot are aligned and distributed. Then control the moving chamber to return from the second side to the first side. At this time, the outer walls of the fixed cleaning block and the movable cleaning block are in contact with the inner wall of the T-slot, thereby completing the cleaning of metal debris in the T-slot. S6: Finally, control the moving chamber to move back and forth along the length of the worktable multiple times, automatically cleaning the metal debris in the worktable and T-slot, preparing for the next workpiece processing.

[0016] Compared with the prior art, the present invention provides a horizontal milling machine tool and its machining method, which has the following beneficial effects: 1. This invention features an automatically reciprocating cleaning mechanism on the workbench. Utilizing movable cleaning blocks within the cleaning section, the cleaning section unfolds in a straight line during the first cleaning stage, cleaning the workbench surface. In the second cleaning stage, the cleaning section adopts a T-shaped cleaning structure that matches the T-slots, extending into the T-slots to clean them individually. The two cleaning stages are independent of each other. This not only replaces manual cleaning of the workbench, reducing the workload of workers, but also cleans all areas of the workbench surface in the first stage and simultaneously cleans multiple T-slots in the second stage. While ensuring cleaning efficiency, it also prevents the workbench surface and T-slots from contacting the cleaning section simultaneously, avoiding continuous large-area friction between the cleaning section and the workbench surface and slot walls during movement, reducing the occurrence of jamming and making the cleaning process smoother. 2. In this invention, the movable blocks in the cleaning section can move closer or further apart from each other. By changing the magnitude of the current flowing through the electromagnet, the magnetism of the electromagnet changes, thereby altering the distance between the different movable blocks. This allows the width of the T-shaped cleaning structure composed of the movable and fixed cleaning blocks to be adjusted as needed. This not only adapts to the cleaning work of more T-shaped grooves but also changes the tightness between the T-shaped groove and the inner wall of the groove to accommodate the cleaning operation of metal debris of different particle sizes. 3. During the cleaning process of the cleaning unit, the present invention coordinates with the air guiding mechanism to control the opening and closing of different air inlets, thereby causing different chambers of the cleaning unit to blow air outward. This achieves the characteristics of a wide air blowing range when cleaning the workbench surface and a narrow air blowing range when cleaning the groove. This makes the air blowing intensity greater during the cleaning process in the groove, so that the debris in the groove can be cleaned out with a greater air blowing intensity and the cooperation of the cleaning unit, further reducing the occurrence of jamming in the cleaning unit.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1 - Figure 11 This application provides a horizontal milling machine tool, including a machine body and a worktable 1 mounted on the machine body. The worktable 1 has several parallel T-slots 101. It also includes a movable chamber 2 capable of reciprocating along the length of the worktable 1, and the movable chamber 2 can also move vertically. The movable chamber 2 is equipped with a cleaning mechanism for cleaning the worktable 1 and the T-slots 101. By reciprocating on the worktable 1, the movable chamber 2 drives the cleaning mechanism to repeatedly clean the worktable 1 and the T-slots 101, replacing manual cleaning, improving cleaning efficiency, and reducing the workload of workers.

[0021] The workbench 1 has a linear slide table arranged along its length on its side. The linear slide table has a slide block, and a cylinder is fixedly mounted on the slide block along the height of the workbench 1. The movable end of the cylinder is fixedly connected to the movable chamber 2 and can drive the movable chamber 2 to move vertically up and down. The linear slide table controls the reciprocating movement of the movable chamber 2 and the cleaning mechanism on the workbench 1. The cylinder changes the height of the cleaning mechanism, enabling the cleaning structure to clean the workbench 1 and the T-slot 101.

[0022] Furthermore, the cleaning mechanism includes a plurality of cleaning sections 3 disposed on the side of the movable chamber 2 facing the workbench 1. The plurality of cleaning sections 3 and the plurality of T-shaped grooves 101 are arranged in a one-to-one correspondence. Each cleaning section 3 includes a fixed cleaning block 301 and a movable cleaning block 302. The fixed cleaning block 301 is fixedly disposed on the movable chamber 2. The number of movable cleaning blocks 302 is at least one and is slidably disposed on the movable chamber 2 along the width direction of the workbench 1. There is a gap between two adjacent fixed cleaning blocks 301, and the movable cleaning block 302 can slide along the width direction of the workbench 1 to fill the gap.

[0023] The fixed cleaning block 301 is fixedly connected to the bottom of the mobile compartment 2. The fixed cleaning block 301 is in the shape of an inverted T and matches the shape of the T-shaped groove 101. However, the height of the fixed cleaning block 301 is higher than the depth of the T-shaped groove 101 to prevent the bottom surface of the mobile compartment 2 from contacting the table surface of the workbench 1 when the fixed cleaning block 301 extends into the T-shaped groove 101, which would increase the friction.

[0024] On the other hand, when there is one active cleaning block 302, the active cleaning block 302 and the fixed cleaning block 301 have the same shape, and the distance between adjacent fixed cleaning blocks 301 is not greater than the width of the active cleaning block 302, so that the active cleaning block 302 can fill the gap between adjacent fixed cleaning blocks 301; when there are two active cleaning blocks 302, the active cleaning block 302 is L-shaped, the two active cleaning blocks 302 are symmetrically arranged in the width direction of the workbench 1, and the top of the active cleaning block 302 is slidably connected to the bottom wall of the moving chamber 2, so that the two active cleaning blocks 302 can move closer or further away from each other.

[0025] Furthermore, when the movable compartment 2 moves from the first side to the second side of the workbench 1, the movable cleaning block 302 slides to fill the gap between adjacent fixed cleaning blocks 301. Several fixed cleaning blocks 301 and several movable cleaning blocks 302 are joined to form a straight cleaning structure adapted to the width of the workbench 1, to scrape away metal debris from the top surface of the workbench 1. At this time, the bottom surfaces of both the fixed cleaning blocks 301 and the movable cleaning blocks 302 are in contact with the surface of the workbench 1 to scrape away debris from the surface of the workbench 1. It should be noted that the distance between adjacent T-slots 101 is no greater than the width of the T-slot 101, so that when two movable cleaning blocks 302 move away from each other until they are in contact with movable cleaning blocks 302 in adjacent cleaning sections 3, they can fill the gap between adjacent fixed cleaning blocks 301, thereby covering the width direction of the workbench 1.

[0026] When the movable chamber 2 moves from the second side to the first side of the workbench 1, the movable cleaning block 302 slides back to its original position to combine with the fixed cleaning block 301 to form a T-shaped cleaning structure. The T-shaped cleaning structure moves vertically downward into the T-shaped groove 101 to clean the metal debris in the T-shaped groove 101. At this time, both the fixed cleaning block 301 and the movable cleaning block 302 are in contact with the groove wall of the T-shaped groove 101, thereby cleaning the debris in the T-shaped groove 101.

[0027] During the two cleaning processes of the cleaning mechanism, the workbench 1 is first cleaned, and the debris on the workbench is scraped off. During the movement of the cleaning unit 3, some debris falls into the T-groove 101, which makes it easier to clean the debris in the T-groove 101 during the return process of the cleaning unit 3. During the cleaning of the T-groove 101, a small amount of debris will splash onto the workbench 1. At this time, it is necessary to repeat the back-and-forth movement of the cleaning unit 3 on the workbench 1 to continuously clean the workbench 1 until the cleaning operation is completed.

[0028] In this embodiment, each cleaning section 3 contains two movable cleaning blocks 302, which are slidably disposed on the moving chamber 2 along the width direction of the workbench 1. When the two movable cleaning blocks 302 move away from each other until the distance between them is equal to the width of the fixed cleaning block 301, the movable cleaning blocks 302 and the fixed cleaning blocks 301 are staggered, and the facing surfaces of the movable cleaning blocks 302 in two adjacent cleaning sections 3 are in a close-fitting state. This allows the movable cleaning blocks 302 to fill the gap between adjacent fixed cleaning blocks 301, thereby increasing the overall width of the cleaning section 3. This ensures that the width of the combined cleaning sections 3 is not less than the width of the workbench 1, allowing the cleaning section 3 to scrape debris from one side to the other during movement.

[0029] When the two movable cleaning blocks 302 approach each other to a mating state, they combine to form a cleaning structure with the same shape as the fixed cleaning block 301 and are aligned with it. At this time, the cleaning part 3, after the combination of the fixed cleaning block 301 and the movable cleaning block 302, is inverted T-shaped, which matches the shape of the T-groove 101. The moving chamber 2 is lowered by a cylinder, so that the cleaning part 3 is directly facing the T-groove 101. Then, the moving chamber 2 is moved back by a linear slide, so that the cleaning part 3 enters the T-groove 101 to clean the debris inside.

[0030] The outer walls of the fixed cleaning block 301 and the movable cleaning block 302 can be fixedly bonded with various cleaning tools such as hard plastic, thin scraper, hard brush, soft brush, and wiping cloth, thereby meeting more cleaning needs of users.

[0031] It should be noted that the top of the movable cleaning block 302 extends into the movable compartment 2 and is connected to a drive mechanism 4. The drive mechanism 4 is used to control the two movable cleaning blocks 302 in each cleaning section 3 to move closer or further apart. The bottom of the movable compartment 2 has a through-hole into which the top of the movable cleaning block 302 can extend. The movable cleaning block 302 can move along the width of the workbench 1 within the through-hole, and the movable cleaning block 302 is slidably connected to the side wall of the through-hole.

[0032] Specifically, such as Figure 4 and Figure 11 As shown, the driving mechanism 4 includes a first iron plate 401 and a second iron plate 402 respectively fixedly connected to the top of the two movable cleaning blocks 302. A horizontal sliding plate is connected to the top of the movable cleaning block 302. The second iron plate 402 is fixedly connected to the end of the horizontal sliding plate away from the movable cleaning block 302. The width of the horizontal sliding plate is greater than the width of the through-hole at the bottom of the movable compartment 2, so that when the two movable cleaning blocks 302 are attached, the horizontal sliding plate can completely cover the through-hole. In addition, sealing gaskets are fixedly glued to the facing surfaces of the horizontal sliding plates at the top of the two movable cleaning blocks 302 to seal the contact surfaces when they are attached.

[0033] The first iron plate 401 and the second iron plate 402 are symmetrically distributed along the width of the workbench 1, forming a movable cavity between them. An electromagnet 403 is fixedly installed in the movable cavity. The electromagnet 403 has two magnetic ends, which face the first iron plate 401 and the second iron plate 402 respectively. Springs 404 are provided between the electromagnet 403 and the first iron plate 401, and between the electromagnet 403 and the second iron plate 402. The springs 404 are distributed along the width of the workbench 1, with their two ends abutting against the electromagnet 403 and the facing surfaces of the first iron plate 401 and the second iron plate 402 respectively. In its natural state, the springs 404 are in a compressed state.

[0034] Among them, such as Figure 4 and Figure 11 As shown, the top surfaces of the first iron plate 401 and the second iron plate 402 have a fixed, detachable top plate that is installed inside the mobile compartment 2. This top plate is fixed to the inner bottom wall or inner side wall of the mobile compartment 2 by bolts or screws, and covers all of the first iron plate 401 and the second iron plate 402. Both the first iron plate 401 and the second iron plate 402 slide on the bottom of the top plate and are sealed to the bottom surface of the top plate. A mounting protrusion is fixedly provided at the bottom of the top plate, directly opposite the movable cavity, for mounting the power magnet 403. Cylindrical limiting sleeves are fixed on both sides of the mounting protrusion to accommodate the spring 404, thereby making the extension and contraction of the spring 404 more stable.

[0035] It is worth mentioning that a first connecting plate 405 is fixedly connected to the same side of several first iron plates 401, and a second connecting plate 406 is fixedly connected to the side of several second iron plates 402 away from the first connecting plate 405. The first connecting plate 405 is used to drive the several first iron plates 401 to move synchronously, and the second connecting plate 406 is used to drive the several second iron plates 402 to move synchronously. Therefore, only one electromagnet 403 is needed to control the movement of all the first iron plates 401 and second iron plates 402, thereby driving the movement of all the movable cleaning blocks 302. Furthermore, the top plates on the top of the first iron plates 401 and second iron plates 402 completely cover the first connecting plate 405 and the second connecting plate 406. The first connecting plate 405 and the second connecting plate 406 also slide on the bottom of the top plate, and the top surface and the bottom surface of the top plate are sealed and fitted together to avoid affecting the subsequent air blowing operation.

[0036] Specifically, when the electromagnet 403 is energized, it generates a magnetic attraction force on the first iron plate 401 and the second iron plate 402. This magnetic attraction force is greater than the elastic force exerted by the spring 404 on the first iron plate 401 and the second iron plate 402, plus the frictional force between the first iron plate 401, the second iron plate 402 and the top plate. This causes the first iron plate 401 and the second iron plate 402 to move closer together until the two movable cleaning blocks 302 are pressed together. When the electromagnet 403 is de-energized, the spring 404 will reset the first iron plate 401 and the second iron plate 402, causing the two movable cleaning blocks 302 to move away from each other and unfold.

[0037] The on / off state of the electromagnet 403 can be controlled by a sensor. For example, a power supply for the electromagnet 403 is installed in the mobile compartment 2 and electrically connected to the electromagnet 403. An electromagnetic relay is installed in the line between the power supply and the electromagnet 403 to receive the signal from the sensor and amplify the power to drive the electromagnet 403. The sensor is a proximity position sensor, which is installed on the side of the mobile compartment 2 or on the slide of the linear slide. Infrared trigger sensing points corresponding to the position sensor are set at both ends of the linear slide. When the sensor moves to the corresponding position with the slide, it will send a signal to the electromagnetic relay to control the on / off state of the electromagnet 403.

[0038] Furthermore, both the fixed cleaning block 301 and the movable cleaning block 302 have an internal hollow structure. A partition plate 3011 is fixedly provided in the inner cavity of the fixed cleaning block 301, which divides the inner cavity of the fixed cleaning block 301 into a first chamber 3012 and a second chamber 3013. The first chamber 3012 is located on the side closer to the movable cleaning block 302, and the second chamber 3013 is located on the side away from the movable cleaning block 302. Air blowing holes are provided on the first chamber 3012, the second chamber 3013, and the movable cleaning block 302 for blowing air onto the table surface of the workbench 1 or into the T-shaped groove 101. Therefore, when the cleaning unit 3 cleans the workbench 1 or the T-slot 101, there is not only the thrust of the mechanical equipment, but also the wind power that can replace the spray gun to clean the debris. It can not only blow away most of the debris before the cleaning unit 3 comes into contact with the debris, reducing the obstruction to the movement of the cleaning unit 3, but also blow away some fine metal powder during the cleaning process of the cleaning unit 3, so as to avoid the cleaning unit 3 not being able to completely remove the metal powder.

[0039] Specifically, the air blowing holes on the first chamber 3012 are located on the side facing the movable cleaning block 302, the air blowing holes on the second chamber 3013 are located on the side away from the movable cleaning block 302, and the air blowing holes on the movable cleaning block 302 are located on the side away from the fixed cleaning block 301. The movable chamber 2 is provided with an air guiding mechanism. When the cleaning part 3 cleans the table surface of the workbench 1, the air guiding mechanism is used to control the gas flow in the movable chamber 2 to the first chamber 3012 and the movable cleaning block 302. When the cleaning part 3 cleans the T-shaped groove 101, the air guiding mechanism is used to control the gas flow in the movable chamber 2 to the second chamber 3013.

[0040] Therefore, when the cleaning unit 3 cleans the surface of the workbench 1, the first chamber 3012 and the movable cleaning block 302 blow air outwards, such as... Figure 6 and Figure 7 As shown, at this time, the movable cleaning block 302 is in the extended state, expanding the airflow range. The first chamber 3012 and the movable cleaning block 302 can perform airflow operations on all areas of the workbench 1. When the cleaning unit 3 cleans the T-slot 101, the movable cleaning block 302 is in the retracted state. At this time, only the second chamber 3013 blows air outward, reducing the airflow range and the number of airflow holes opened. This increases the airflow intensity from the second chamber 3013, making it easier to disperse the debris accumulated in the T-slot 101 and allowing the cleaning unit 3 to move more smoothly.

[0041] In this embodiment, the bottom wall of the mobile compartment 2 is provided with a first air inlet 201, a second air inlet 202 and a third air inlet 203. The first air inlet 201 is connected to the first chamber 3012, the second air inlet 202 is connected to the second chamber 3013, and the third air inlet 203 is connected to the movable cleaning block 302. The air guiding mechanism is used to control the opening and closing of the air inlets.

[0042] The first chamber 3012 and the first air inlet 201 are connected by a first air guide tube, the second chamber 3013 and the second air inlet 202 are connected by a second air guide tube, and the inner cavity of the movable cleaning block 302 and the third air inlet 203 are connected by a third air guide tube. The first and second air guide tubes can be made of either rigid or flexible materials, while the third air guide tube must be made of a flexible material, such as polyurethane tubing, which has excellent flexibility and can be bent and twisted freely to avoid hindering the movement of the movable cleaning block 302.

[0043] like Figure 8 and Figure 9 As shown, the air guiding mechanism includes a first sealing plate 5 and a second sealing plate 6 fixedly disposed on the side of the first connecting plate 405 opposite to the second connecting plate 406, and a third sealing plate 7 fixedly disposed on the side of the second connecting plate 406 opposite to the first connecting plate 405. Sealing gaskets are fixedly adhered to the sides of the first sealing plate 5, the second sealing plate 6, and the third sealing plate 7 facing the bottom wall of the mobile chamber 2, and are sealed and fitted tightly to the inner bottom wall of the mobile chamber 2.

[0044] When the cleaning unit 3 cleans the workbench 1, the first sealing plate 5 and the first air inlet 201 are misaligned, the second sealing plate 6 and the second air inlet 202 are aligned, and the third sealing plate 7 and the third air inlet 203 are misaligned. At this time, the first air inlet 201 and the third air inlet 203 are open, while the second air inlet 202 is blocked by the second sealing plate 6 and is in a closed state. Therefore, the air blowing holes on the first chamber 3012 and the movable cleaning block 302 will blow air outward.

[0045] When the cleaning section 3 cleans the T-shaped groove 101, the first sealing plate 5 and the first air inlet 201 are aligned, the second sealing plate 6 and the second air inlet 202 are misaligned, and the third sealing plate 7 and the third air inlet 203 are aligned. At this time, the first air inlet 201 and the third air inlet 203 are in a closed state, and the second air inlet 202 is in an open state. Therefore, the air blowing hole on the second chamber 3013 will blow air outward.

[0046] Since the top plate on the top of the first iron plate 401 and the second iron plate 402 is fixedly installed in the mobile chamber 2 by bolts, and the top plate covers all the first iron plate 401 and the second iron plate 402, as well as the first connecting plate 405 and the second connecting plate 406, the first iron plate 401, the second iron plate 402, the first connecting plate 405 and the second connecting plate 406 slide between the top plate and the bottom wall of the mobile chamber 2, and are sealed and fitted with the bottom surface of the top plate and the bottom wall of the mobile chamber 2, so as to ensure the airtightness of the mobile chamber 2 and prevent gas leakage from the through-hole on the bottom wall of the mobile chamber 2 when the movable cleaning block 302 is in the unfolded state, so that the gas can only be discharged from the air inlet.

[0047] It should be noted that a through hole is provided on the side of the mobile chamber 2 for the air guide tube to pass through, and a sealing ring is provided between the air guide tube and the through hole to ensure airtightness. Gas is directly filled into the inner cavity of the mobile chamber 2 and can be discharged from the exhaust port. In addition, the top of the mobile chamber 2 is fixedly and removably equipped with a cover plate. A sealing gasket is provided between the cover plate and the top of the mobile chamber 2 to ensure a tight seal between the cover plate and the top of the mobile chamber 2. At the same time, it also facilitates the user to remove the cover plate to maintain and replace various internal structures of the mobile chamber 2.

[0048] Example 2: The present invention also proposes a processing method applicable to the horizontal milling machine tool of Example 1, comprising the following steps: First, the workpiece to be processed is fixed on the worktable 1 by the cooperation of the fixture and the T-slot 101. Then, the multi-axis motion control system of the machine tool drives the workpiece and the milling cutter to move so that the workpiece processing area corresponds to the position of the milling cutter of the machine tool.

[0049] Subsequently, the machine tool is started, and the milling cutter processes the workpiece according to the pre-set program instructions at different speeds, feed rates, and milling depths. During the processing, the moving chamber 2 and the cleaning unit 3 are located beside the worktable 1, so they do not affect the movement of the worktable 1 or the processing operation of the milling cutter.

[0050] After the machining is completed, the fixture is disassembled and the workpiece is removed so that the fixture and workpiece are no longer placed on the table 1. The multi-axis moving system controls the table 1 to move away from the milling cutter, so as to avoid the milling cutter from obstructing the movement of the moving chamber 2 and the cleaning section 3.

[0051] Then, the electromagnet 403 is de-energized by the sensor and electromagnetic relay, causing the spring 404 to push the first iron plate 401 and the second iron plate 402 toward opposite sides. This causes the first iron plate 401 and the second iron plate 402 to move the two movable cleaning blocks 302 away from each other until the movable cleaning blocks 302 in the adjacent cleaning sections 3 come into contact, so that the movable cleaning blocks 302 and the fixed cleaning blocks 301 combine to form a straight cleaning structure with a width that matches the width of the workbench 1. At this time, the first sealing plate 5 and the first air inlet 201 are misaligned, the second sealing plate 6 and the second air inlet 202 are aligned, and the third sealing plate 7 and the third air inlet 203 are misaligned. At this time, the first air inlet 201 and the third air inlet 203 are in the open state, while the second air inlet 202 is blocked by the second sealing plate 6 and is in the closed state. Therefore, the air blowing holes on the first chamber 3012 and the movable cleaning blocks 302 will blow air outward. Furthermore, the first iron plate 401, the second iron plate 402, the first connecting plate 405, and the second connecting plate 406 are always located at the bottom of the top plate inside the mobile chamber 2 and are sealed and fitted to the top plate, so that the gas inside the mobile chamber 2 can only be discharged from the exhaust port and will not enter the movable cavity between the first iron plate 401 and the second iron plate 402, nor will it leak from the penetration opening in the bottom wall of the mobile chamber 2.

[0052] Then, the cylinder controls the movement of the chamber 2 and the cleaning section 3 to rise and fall, so that the bottom surfaces of the fixed cleaning block 301 and the movable cleaning block 302 are flush with the surface of the workbench 1. The linear slide controls the movement of the chamber 2 and the cleaning section 3 to move from the first side to the second side along the length of the workbench 1. Thus, the surface of the workbench 1 can be cleaned by the scraping and sweeping of the fixed cleaning block 301 and the movable cleaning block 302 and the blowing of air through the air holes.

[0053] After the first cleaning of the workbench 1 is completed, the electromagnet 403 is energized to bring the two movable cleaning blocks 302 in each cleaning section 3 closer together until they are in contact, filling the gap between adjacent fixed cleaning blocks 301, so that they are combined with the fixed cleaning blocks 301 to form a T-shaped cleaning structure that matches the shape of the T-shaped groove 101. At this time, the first sealing plate 5 and the first air inlet 201 are aligned, the second sealing plate 6 and the second air inlet 202 are misaligned, and the third sealing plate 7 and the third air inlet 203 are aligned. At this time, the first air inlet 201 and the third air inlet 203 are in a closed state, and the second air inlet 202 is in an open state. Therefore, the air blowing hole on the second chamber 3013 will blow air outward.

[0054] Then, the cylinder controls the moving chamber 2 to drive the cleaning part 3 to descend, so that the cleaning part 3 is directly facing one end of the T-shaped groove 101. Then, the linear slide table drives the moving chamber 2 and the cleaning part 3 to move from the second side to the first side of the workbench 1, so that the fixed cleaning block 301 and the movable cleaning block 302 move in the T-shaped groove 101, and the bottom surfaces of the fixed cleaning block 301 and the movable cleaning block 302 are in contact with the table surface of the workbench 1, thus completing the cleaning of metal debris from the table surface of the workbench 1.

[0055] Finally, the control unit 2 moves back and forth along the length of the worktable 1 multiple times to automatically clean the metal debris in the worktable 1 and the T-slot 101 until it is clean, in preparation for the next workpiece processing.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
