Description

Technical Field

[0001] This invention relates to the field of machine tool double-door technology, specifically to a machine tool double-door structure. Background Technology

[0002] Currently, most mainstream CNC machine tools adopt a double-door structure. While this double-door design saves space, it generally presents the problem of the fixed, visible glass being difficult to clean. Because the glass cannot be removed individually and the space behind the door is narrow, cleaning is difficult and risky. Existing technology struggles to effectively solve this problem without the aid of external tools. Summary of the Invention

[0003] The purpose of this invention is to provide a machine tool double-door structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a machine tool double-door structure, including a circular rail and a linear rail, wherein there are two circular rails, and a loading door and a side door are respectively provided on the surface of the two circular rails. The bottom of the loading door and the side door are fixedly connected to a support sheet metal, and there are multiple support sheet metals. One side of each of the multiple support sheet metals is rotatably connected to a grooved roller and an anti-detachment bearing. The grooved roller and the anti-detachment bearing are both in contact with the surface of the circular rail. The linear rail is provided in the top inner cavity of the loading door and the side door. One side of the feeding door is fixedly connected to an extruded sheet metal, and one side of the side door is fixedly connected to a self-clamping sealing strip, which is pressed against the extruded sheet metal. An observation window is provided on one side of both the loading door and the side door. A first observation glass is fixedly connected to the inner wall of the observation window. A frame strip is fixedly connected between the observation window and the first observation glass. A lifting mechanism is provided on one side of the loading door. A cleaning structure is provided in the lifting mechanism.

[0005] Preferably, the lifting mechanism includes a bracket, one side of which is fixedly connected to the inner wall of the loading gate, a transmission bearing is fixedly connected to the inner wall of one side of the bracket, a threaded rod is fixedly connected to the inner wall of the inner ring of the transmission bearing, and a guide rod is fixedly connected to the inner wall of the bracket.

[0006] Preferably, the cleaning structure includes a first connector and a second connector, the inner cavity of the first connector is threadedly connected to the surface of the threaded rod, the inner cavity of the second connector is slidably connected to the surface of the guide rod, and a movable housing is fixedly connected between the first connector and the second connector, the surface of the movable housing being slidably connected to the inner cavity of the bracket.

[0007] Preferably, a first protective plate is fixedly connected to one side surface of the bracket, the threaded rod is disposed in the inner cavity of the first protective plate, a second protective plate is fixedly connected to the other side surface of the bracket, and the guide rod is disposed in the inner cavity of the second protective plate.

[0008] Preferably, a first motor is fixedly installed on the top of the bracket, a drive gear is fixedly connected to the output end of the first motor, and a driven gear is fixedly connected to one end of the threaded rod, with the teeth of the drive gear and the teeth of the driven gear meshing with each other.

[0009] Preferably, a third protective plate is fixedly connected to the top of the bracket, and the first motor, the driving gear, and the driven gear are all disposed in the inner cavity of the third protective plate.

[0010] Preferably, a mounting plate is inserted into the inner cavity of the movable housing, a wiping layer is fixedly connected to one side of the mounting plate, the wiping layer penetrates the movable housing and fits against the inner wall of the corresponding first observation glass, a sealing plate is fixedly inserted into the inner wall of the movable housing, a pressure block is fixedly connected to one side of the sealing plate, and one side of the pressure block abuts against one side of the mounting plate.

[0011] Preferably, a circular window is provided on one side of the first observation glass of the side door, and a mounting frame is fixedly connected to the inner wall of the circular window. A second observation glass is rotatably connected to the inner cavity of the mounting frame. A second motor is fixedly installed on one side of the mounting frame, and the output end of the second motor is fixedly connected to one side of the second observation glass.

[0012] Preferably, the inner walls of the loading door and the side door are fixedly connected with guide members, which are sleeved on the outer side of the circular rail and the sheet metal of the support seat.

[0013] Preferably, a water receiving tray is provided at the bottom of the flow guide, and the water receiving tray and the flow guide are in communication.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, a round window and a second motor are designed on the first observation glass of the side door. The second motor can drive the second observation glass to rotate at high speed, which is convenient for real-time observation of the internal situation during processing. The loading door and the lower end of the side door are designed with a large-angle guide. On the one hand, it is to better guide the chips and prevent the chips from accumulating. On the other hand, it can hide the built-in track device of the external door, reduce the space occupied by the entire machine tool, and make the machine tool more beautiful. Water splashes towards the closing direction, achieving the first layer of sealing. At the loading door interface, there is also a T-shaped sheet metal and a bent sheet metal at the side door interface, forming two chambers. Under the strong impact of the cutting fluid, most of it will be blocked by the first line of defense of the side door. However, a small amount of cutting fluid will enter from the gap between the side door and the loading door. In the sealed chamber, it will bounce in multiple directions to dissipate its kinetic energy, and then flow into the water receiving tray along the guide. Basically, all the excess cutting fluid can be intercepted in the first chamber. The remaining oil mist will also lose kinetic energy by going back and forth in the two chambers, and finally be blocked by the self-clamping sealing strip and guided to the water receiving tray, achieving a perfect sealing function. There is also a mechanical seal structure with sheet metal flange on the other side of the loading door and the side door. The blocked cutting fluid will flow back into the machine tool through the guide groove.

[0015] 2. In this invention, the first motor is fixedly installed on the top of the bracket and connected to the drive gear through its output shaft. The drive gear meshes with the driven gear fixedly sleeved on the top of the threaded rod. Therefore, when the drive gear rotates, it can drive the threaded rod to rotate. The transmission bearing is embedded in the inner wall hole on one side of the bracket. The inner ring of the transmission bearing is fixedly connected to the threaded rod to ensure that the threaded rod maintains axial stability during rotation. The guide rod is arranged parallel to the other side of the threaded rod and fixedly connected to the inner wall of the other side of the bracket. It is used to guide the cleaning structure to slide smoothly in the vertical direction and prevent it from twisting or shaking during lifting.

[0016] 3. In this invention, the first connecting member has an internal thread that matches the threaded rod. When the threaded rod rotates, the connecting member generates a linear displacement along the axial direction. The second connecting member is fitted onto the guide rod and is only allowed to slide along the guide rod direction, thereby constraining the entire cleaning structure to only perform vertical lifting and lowering movements. The movable housing has a detachable mounting plate inside, and its fixed connection to the first observation glass has a flexible wiping layer. The material can be microfiber cloth, polyurethane sponge, or silicone scraper, etc., which can effectively remove cutting fluid residue, oil film, and dust from the glass surface without scratching the glass. The wiping layer extends outward through a slot on the side wall of the movable housing, always maintaining close contact with the inner wall of the first observation glass. When the lifting mechanism drives the movable housing to move up and down, the wiping layer simultaneously sweeps the glass surface, achieving fully automatic cleaning. To facilitate maintenance and replacement of wiping consumables, a sealing plate is vertically inserted into the inner cavity of the housing, and a pressure block is fixed on the side facing the mounting plate. This pressure block continuously presses against the edge of the mounting plate, ensuring that the wiping layer does not loosen or fall off during operation, and allowing operators to easily remove the mounting plate for cleaning or replacement when the machine is stopped.

[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 Figures 1 to 10 This invention provides a technical solution: a machine tool double-door structure, including two circular rails 1 and two linear rails 23. A loading door 2 and a side door 3 are respectively provided on the surfaces of the two circular rails 1. Support sheet metal 4s are fixedly connected to the bottom of the loading door 2 and the side door 3. Multiple support sheet metal 4s are provided, and grooved rollers 5 and anti-detachment bearings 6 are rotatably connected to one side of each support sheet metal 4. The grooved rollers 5 and anti-detachment bearings 6 are both in contact with the surface of the circular rails 1. The linear rail 23 is located in the top inner cavity of the loading door 2 and the side door 3. A loading door 2 is fixedly connected to one side of... The extruded sheet metal 7 and the side door 3 are fixedly connected to one side with a self-clamping sealing strip 8, which is pressed against the extruded sheet metal 7. Both the loading door 2 and the side door 3 have observation windows 9 on one side. A first observation glass 10 is fixedly connected to the inner wall of the observation window 9, and a frame strip 11 is fixedly connected between the observation window 9 and the first observation glass 10. A lifting mechanism 12 is provided on one side of the loading door 2, and a cleaning structure 13 is provided in the lifting mechanism 12. This double-door structure mainly consists of a loading door 2 and a side door 3. Both doors are designed as external doors, relying on a circular... The door opens and closes via rail 1. Multiple support plates 4 are installed at the lower end of the door. Grooved rollers 5 and anti-detachment bearings 6, matching the circular rail 1, are mounted on the support plates 4. After inserting into the circular rail 1, the grooved rollers 5 provide the main support for the door. A straight rail 23 is also installed at the upper end of the door and fixed to the frame, limiting the door's rotation direction on the circular rail 1 and allowing for smooth sliding. The outer observation windows 9 of the loading door 2 and side door 3 are decorated with frame strips 11, adding rounded elements to the machine tool and making the lines more graceful. When opening the door, the side door 3 must be opened first. When opening the loading door 2, the opposite is true when closing the door. The loading door 2 must be closed first, followed by the side door 3. When the loading door 2 is closed, the self-clamping sealing strip 8 installed on the side door 3 contacts and presses against the extruded sheet metal 7 on one side of the loading door 2, ensuring direct sealing of cutting fluid and oil mist. Before this sealing, there will be a bend in the thin sheet metal at the interface of the side door 3, leaving a small gap between it and the loading door 2. This can prevent the cutting fluid from washing back into the loading door 2. Through the cooperation of the lifting mechanism 12 and the cleaning structure 13, the cleanliness of the first observation glass 10 in the loading door 2 can be ensured, minimizing liquid splashing and residue.

[0021] As a further definition of the feeding door 2 and side door 3 of the present invention, a circular window 17 is provided on one side of the first observation glass 10 of the side door 3. A mounting frame 18 is fixedly connected to the inner wall of the circular window 17. A second observation glass 19 is rotatably connected to the inner cavity of the mounting frame 18. A second motor 20 is fixedly installed on one side of the mounting frame 18. The output end of the second motor 20 is fixedly connected to one side of the second observation glass 19. A guide member 21 is fixedly connected to the inner wall of both the feeding door 2 and the side door 3. The guide member 21 is sleeved on the outside of the circular rail 1 and the sheet metal support 4. The bottom of the guide component 21 is provided with a water receiving tray 22, which is connected to the guide component 21. A round window 17 and a second motor 20 are designed on the first observation glass 10 of the side door 3. The second motor 20 can drive the second observation glass 19 to rotate at high speed, which is convenient for real-time observation of the internal situation during processing. The lower end of the loading door 2 and the side door 3 is designed with a large-angle guide component 21. On the one hand, it is to better guide the chips and prevent the chips from accumulating. On the other hand, it can hide the built-in track device of the external door, reduce the space occupied by the entire machine tool, and make the machine tool more beautiful. Water splashes towards the closing direction, achieving the first layer of sealing. At the interface of the loading door 2, there is also a T-shaped sheet metal and a bent sheet metal at the interface of the side door 3, forming two chambers. Under the impact of strong cutting fluid, most of it will be blocked by the first line of defense of the side door 3. However, a small amount of cutting fluid will enter from the gap between the side door 3 and the loading door 2. It will bounce in multiple directions in the sealed chamber to dissipate its kinetic energy, and then flow into the water receiving tray 22 along the guide 21. Basically, all the excess cutting fluid can be intercepted in the first chamber. The remaining oil mist will also lose kinetic energy by repeatedly turning back in the two chambers, and finally be blocked by the self-clamping sealing strip 8 and guided to the water receiving tray 22 to achieve a perfect sealing function. There is also a mechanical seal structure with sheet metal flange on the other side of the loading door 2 and the side door 3. The blocked cutting fluid will flow back into the machine tool through the guide groove.

[0022] The specific implementation of this embodiment is as follows: This double-door structure mainly consists of a loading door 2 and a side door 3. Both doors are designed as external doors, relying on a circular rail 1 fixed to the main body for opening and closing. Multiple support sheet metal 4s are installed at the lower end of the doors. Grooved rollers 5 and anti-detachment bearings 6, matching the circular rail 1, are installed on the support sheet metal 4s. After inserting into the circular rail 1, the grooved rollers 5 provide the main support for the door. A straight rail 23 is also installed at the upper end of the door and fixed to the frame, restricting the rotation direction of the door on the circular rail 1, allowing the door to slide smoothly on the circular rail 1. The corners of the external observation windows 9 of the loading door 2 and the side door 3 are decorated with frame strips 11 to enhance the machine tool's rounded elements and make the appearance lines more graceful. When opening the doors, the side door 3 must be opened first, followed by the loading door 2; conversely, when closing the doors, the loading door 2 must be closed first, followed by the side door 3. When the loading door 2 is closed, the self-clamping mechanism installed on the side door 3... The sealing strip 8 contacts and presses against the extruded sheet metal 7 on one side of the loading door 2 to ensure direct sealing of cutting fluid and oil mist. Before this sealing, there is a thin sheet metal bend at the interface of the side door 3, leaving a small gap between it and the loading door 2. This can prevent cutting fluid from washing back into the loading door 2. The cooperation between the lifting mechanism 12 and the cleaning structure 13 can ensure the cleanliness of the first observation glass 10 in the loading door 2 and minimize liquid splashing and residue. A round window 17 and a second motor 20 are designed on the first observation glass 10 of the side door 3. The second motor 20 can drive the second observation glass 19 to rotate at high speed, which is convenient for real-time observation of the internal situation during processing. The loading door 2 and the side door 3 are designed with a large-angle guide 21. On the one hand, it is to better guide chips and prevent chip accumulation. On the other hand, it can hide the internal track device of the external door, reduce the space occupied by the entire machine tool, and make the machine tool more beautiful. Water splashes towards the closing direction, achieving the first layer of sealing. At the interface of the loading door 2, there is also a T-shaped sheet metal and a bent sheet metal at the interface of the side door 3, forming two chambers. Under the impact of strong cutting fluid, most of it will be blocked by the first line of defense of the side door 3. However, a small amount of cutting fluid will enter from the gap between the side door 3 and the loading door 2. It will bounce in multiple directions in the sealed chamber to dissipate its kinetic energy, and then flow into the water receiving tray 22 along the guide 21. Basically, all the excess cutting fluid can be intercepted in the first chamber. The remaining oil mist will also lose kinetic energy by repeatedly turning back in the two chambers, and finally be blocked by the self-clamping sealing strip 8 and guided to the water receiving tray 22 to achieve a perfect sealing function. There is also a mechanical seal structure with sheet metal flange on the other side of the loading door 2 and the side door 3. The blocked cutting fluid will flow back into the machine tool through the guide groove.

[0023] Example 2: Please refer to Figures 6 to 8This invention provides a technical solution: a machine tool double-door structure. This invention addresses the technical problems mentioned in the background art by making corresponding improvements. The lifting mechanism 12 includes a bracket 1201. One side of the bracket 1201 is fixedly connected to the inner wall of the loading door 2. A transmission bearing 1202 is fixedly connected to the inner wall of one side of the bracket 1201. A threaded rod 1203 is fixedly connected to the inner wall of the inner ring of the transmission bearing 1202. A guide rod 1204 is fixedly connected to the inner wall of the bracket 1201. A first protective plate 14 is fixedly connected to one side surface of the bracket 1201. The threaded rod 1203 is disposed in the inner cavity of the first protective plate 14. A second protective plate 15 is fixedly connected to the other side surface of the bracket 1201. The guide rod 1204 is disposed in the inner cavity of the second protective plate 15. The lifting mechanism 12, as the core for realizing the automatic cleaning function of the first observation glass 10 on the loading door 2, is composed of the bracket 1201, the transmission bearing 1202, the threaded rod 1203, and the guide rod 1204. The frame 1201 is fixedly installed on the inner wall of the loading gate 2, providing stable support for the entire lifting mechanism 12. The transmission bearing 1202 is embedded in the inner wall hole on one side of the frame 1201. The inner ring of the transmission bearing 1202 is fixedly connected to the threaded rod 1203 to ensure that the threaded rod 1203 maintains axial stability during rotation. The guide rod 1204 is arranged parallel to the other side of the threaded rod 1203 and fixedly connected to the inner wall of the other side of the frame 1201. It is used to guide the cleaning structure 13 to slide smoothly in the vertical direction and prevent it from twisting or shaking during lifting. In order to further improve the protective performance and service life of the lifting mechanism 12, the first protective plate 14 and the second protective plate 15 are respectively provided on both sides of the frame 1201. The first protective plate 14 covers the outside of the threaded rod 1203 to form a closed cavity, effectively isolating the cutting fluid, metal chips and oil mist from corroding the threaded pair. The second protective plate 15 wraps the guide rod 1204 to prevent foreign objects from adhering and causing increased sliding resistance or jamming.

[0024] As a further definition of the lifting mechanism 12 of the present invention, a first motor 1205 is fixedly mounted on the top of the bracket 1201. A drive gear 1206 is fixedly connected to the output end of the first motor 1205. A driven gear 1207 is fixedly connected to one end of the threaded rod 1203. The teeth of the drive gear 1206 and the driven gear 1207 mesh with each other. A third guard plate 16 is fixedly connected to the top of the bracket 1201. The first motor 1205, the drive gear 1206, and the driven gear 1207 are all disposed within the inner cavity of the third guard plate 16. The motor 1205 can be regarded as the driving source of the lifting mechanism 12. The first motor 1205 is fixedly installed on the top of the bracket 1201 and is connected to the drive gear 1206 through its output shaft. The drive gear 1206 meshes with the driven gear 1207 fixedly sleeved on the top of the threaded rod 1203. Therefore, the drive gear 1206 can drive the threaded rod 1203 to rotate at the same time. In addition, the third guard plate 16 encapsulates the first motor 1205, the drive gear 1206 and the driven gear 1207 inside it to form an independent dustproof and splashproof chamber.

[0025] The specific implementation of this embodiment is as follows: The first motor 1205 is fixedly installed on the top of the bracket 1201 and connected to the drive gear 1206 through its output shaft. The drive gear 1206 meshes with the driven gear 1207 fixedly sleeved on the top of the threaded rod 1203. Therefore, when the drive gear 1206 rotates, it can drive the threaded rod 1203 to rotate. The transmission bearing 1202 is embedded in the inner wall hole on one side of the bracket 1201. The inner ring of the transmission bearing 1202 is fixedly connected to the threaded rod 1203 to ensure that the threaded rod 1203 maintains axial stability during rotation. The guide rod 1204 is arranged parallel to the other side of the threaded rod 1203 and fixedly connected to the inner wall of the other side of the bracket 1201 to guide the cleaning structure 13 to slide smoothly in the vertical direction and prevent it from twisting or shaking during lifting.

[0026] Example 3: Please refer to Figure 6 and Figure 9This invention provides a technical solution: a machine tool double-door structure. This invention addresses the technical problems mentioned in the background art by making corresponding improvements. The cleaning structure 13 includes a first connecting member 1301 and a second connecting member 1302. The inner cavity of the first connecting member 1301 is threadedly connected to the surface of the threaded rod 1203. The inner cavity of the second connecting member 1302 is slidably connected to the surface of the guide rod 1204. A movable housing 1303 is fixedly connected between the first connecting member 1301 and the second connecting member 1302. The surface of the movable housing 1303 is slidably connected to the inner cavity of the bracket 1201. The main body of the cleaning structure 13 consists of a first connector 1301, a second connector 1302, and a movable housing 1303. The first connector 1301 has an internal thread that matches the threaded rod 1203. When the threaded rod 1203 rotates, the connector generates a linear displacement along the axial direction. The second connector 1302 is fitted onto the guide rod 1204 and is only allowed to slide along the direction of the guide rod 1204, thereby constraining the entire cleaning structure 13 to only perform vertical lifting and lowering movements and preventing skew. The two connectors are fixedly connected to the movable housing 1303 to ensure uniform force transmission and synchronous movement.

[0027] As a further definition of the cleaning structure 13 of the present invention, a mounting plate 1304 is inserted into the inner cavity of the movable housing 1303. A wiping layer 1305 is fixedly connected to one side of the mounting plate 1304. The wiping layer 1305 penetrates the movable housing 1303 and adheres to the inner wall of the corresponding first observation glass 10. A sealing plate 1306 is fixedly inserted into the inner wall of the movable housing 1303. A pressure block 1307 is fixedly connected to one side of the sealing plate 1306. One side of the pressure block 1307 abuts against one side of the mounting plate 1304. A detachable mounting plate 1304 is provided inside the movable housing 1303, and a flexible wiping layer 1305 is fixedly connected to the first observation glass 10. The material can be microfiber cloth, polyurethane sponge, or silicone scraper, etc., which can effectively clean the glass surface. The wiping layer 1305 removes cutting fluid residue, oil film, and dust without scratching the glass. It extends outward through a slot on the side wall of the movable housing 1303 and always keeps in close contact with the inner wall of the first observation glass 10. When the lifting mechanism 12 drives the movable housing 1303 to move up and down, the wiping layer 1305 simultaneously sweeps the glass surface to achieve fully automatic cleaning. To facilitate maintenance and replacement of wiping consumables, the sealing plate 1306 is vertically inserted into the inner cavity of the housing, and a pressure block 1307 is fixedly installed on the side facing the mounting plate 1304. The pressure block 1307 continuously presses against the edge of the mounting plate 1304, which not only ensures that the wiping layer 1305 does not loosen or fall off during operation, but also allows the operator to easily pull out the mounting plate 1304 for cleaning or replacement when the machine is stopped.

[0028] The specific implementation of this embodiment is as follows: The first connecting member 1301 has an internal thread that matches the threaded rod 1203. When the threaded rod 1203 rotates, the connecting member generates a linear displacement along the axial direction. The second connecting member 1302 is fitted onto the guide rod 1204, allowing it to slide only along the direction of the guide rod 1204, thereby constraining the entire cleaning structure 13 to only perform vertical lifting and lowering movements. The movable housing 1303 has a detachable mounting plate 1304 inside, which is fixedly connected to the first observation glass 10 with a flexible wiping layer 1305.

The wiping layer 1305 extends outward through the through groove on the side wall of the movable housing 1303, and always maintains close contact with the inner wall of the first observation glass 10. When the lifting mechanism 12 drives the movable housing 1303 to move up and down, the wiping layer 1305 simultaneously sweeps the glass surface to achieve fully automatic cleaning.
