Description

Technical Field

[0001] The present invention relates to the field of boring and milling machining, and more particularly to a horizontal machining center that can be opened in two parts. Background Art

[0002] In the mechanical processing industry, horizontal machining centers are extremely key equipment and are widely used in the processing and manufacturing of various precision components. However, there are many problems with existing horizontal machining centers, seriously affecting their processing efficiency and usability.

[0003] Among them, the most prominent is the unreasonable design of the swing diameter and the door opening width. The swing diameter of existing horizontal machining centers is much larger than the door opening width, which results in the swing diameter not being fully utilized during actual processing, causing a great waste of resources. Many processing tasks that could originally be completed within a larger swing diameter range cannot be achieved due to the limitation of the door opening width, reducing the processing capacity of the equipment.

[0004] At the same time, the mismatch between the swing diameter and the door opening width makes it necessary to perform the redundant action of removing the door when loading and unloading workpieces. Operators need to spend extra time and effort to disassemble and install the door body, which not only increases the complexity of the operation but also prolongs the auxiliary time of processing, reducing production efficiency. Moreover, frequent door removal operations will also affect the stability and sealing performance of the equipment. Frequent opening and closing of the equipment can easily cause the connection parts between the door body and the fuselage to become loose, affecting the overall structural stability of the equipment and thus affecting the processing accuracy. In addition, the decline in sealing performance may also cause cutting fluid, debris, etc. to enter the equipment during processing, damaging equipment components and shortening the service life of the equipment.

[0005] These problems seriously restrict the application and development of horizontal machining centers in modern manufacturing, and there is an urgent need for a new design to solve these drawbacks and improve the performance and usage efficiency of the equipment. Summary of the Invention

[0020] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation modes.

[0021] Refer to Figures 1 to 9 , a horizontal machining center capable of being opened in two parts, including a body 1 and a boring and milling machine 12 arranged at the upper end of the body 1, and further including: An inner main body 2, arranged at the upper end of the body 1 and connected to the body 1; Two inner doors 4, symmetrically arranged on both sides of the inner main body 2; Two outer doors 5, hinged to the side close to the two inner doors 4, and each outer door 5 is provided with a door handle 7; A top cover 37, rotatably arranged at the upper end of the inner main body 2; Two dust covers 38, respectively fixedly connected to both sides of the inner main body 2; Two protection mechanisms 13 (as Figure 5 shown), respectively arranged on one side of the inner main body 2 close to the two dust covers 38. The protection mechanism 13 includes two transfer buckle plates 19, two main magnets 22, two sub-magnets 23, two electromagnets 32 and two limit inclined rods 33. The two transfer buckle plates 19 are respectively slidably connected to the side wall of the inner main body 2. The two main magnets 22 are respectively fixedly connected to the side close to the boring and milling machine 12 of the two transfer buckle plates 19. The two electromagnets 32 are respectively fixedly connected to the outer wall of the two inner main bodies 2. The two limit inclined rods 33 are respectively slidably arranged on the side of the outer wall of the inner main body 2 away from the two electromagnets 32. The two sub-magnets 23 are respectively arranged on the side of the two limit inclined rods 33 close to the two electromagnets 32.

[0022] When the device is in operation and the loading and unloading of the boring and milling machine 12 is required, the two electromagnets 32 stop running. At this time, the main magnet 22 and the auxiliary magnet 23 are disengaged from the electromagnets 32 respectively. Subsequently, the operator pulls the door handle 7 to drive the outer door 5 and the inner door 4 to move. During the movement of the outer door 5 and the inner door 4, the turning diameter of the workpiece is protected to the maximum extent. At the same time, the side of the inner door 4 close to the outer door 5 is hinged, that is, to prevent interference between the door handle 7 and the inner main body 2 when the inner door 4 is about to be opened to the end.

[0023] During the opening process of the door handle 7, the inner door 4 drives the corresponding adapter buckle plate 19 to move (the specific connection relationship will be described later), until the adapter buckle plate 19 is positioned by the limit inclined rod 33 to prevent the inner door 4 and the outer door 5 from resetting by themselves during the machining of the workpiece by the boring and milling machine 12.

[0024] When the inner door 4 and the outer door 5 close the inner main body 2, the two electromagnets 32 are started. Subsequently, the operator pushes the inner door 4 and the outer door 5 to move until the two output ends of the electromagnet 32 are adsorbed to the main magnet 22 and the auxiliary magnet 23 respectively (refer to Figure 9 , the upper output end located above the electromagnet 32 is adsorbed to the main magnet 22, and the lower output end located below the electromagnet 32 is adsorbed to the auxiliary magnet 23). During this process, the opening width of the inner main body 2 is increased. Since there is no cross beam at the feeding port of the inner main body 2, the operator can hoist the workpiece into the inner main body 2 at will, so as to facilitate the boring and milling machine 12 to process the workpiece.

[0025] In order to prevent interference between the outer door 5 and the inner main body 2 when the inner door 4 moves to the limit position of the inner main body 2, the following features are specifically set: A number of hinges are provided on the side of the outer door 5 close to the inner door 4. One end of the hinge is fixedly connected to the inner door 4, and the other end is fixedly connected to the outer door 5. Through the connection of the hinges, the outer door 5 and the inner door 4 can rotate flexibly, ensuring the smooth opening and closing of the door body (i.e., the outer door 5 and the inner door 4), effectively avoiding jamming or interference during the opening and closing of the outer door 5 and the inner door 4, and ensuring the stability of the equipment operation.

[0026] In order to limit the movement of the inner door 4 to ensure that the inner door 4 can be parallel to the side wall of the inner main body 2 when it needs to be opened, and perpendicular to the side wall of the inner main body 2 when it is closed, the following features are specifically set: The protection mechanism 13 further includes an L-shaped guide rail 8 and a number of pulleys 9. The L-shaped guide rail 8 is fixedly connected to the upper end of the inner main body 2 (as Figure 8 shown), and a number of pulleys 9 are respectively rotatably connected to the upper ends of the inner door 4 and the outer door 5 (as Figure 2As shown in the figure, a wheel groove is formed in the middle of the L-shaped guide rail 8, and a number of pulleys 9 are respectively connected to the wheel groove in a rolling manner. When the inner door 4 and the outer door 5 move, the pulleys 9 roll in the wheel groove to ensure that the inner door 4 is parallel to the side wall of the inner main body 2 when it is opened and perpendicular to the side wall of the inner main body 2 when it is closed, thereby realizing effective limit for the movement of the door body.

[0027] In order to limit the lower end of the inner door 4 and prevent the inner door 4 from getting stuck when moving to the corner of the L-shaped guide rail 8, the inner door 4 is specifically provided with the following features: The protection mechanism 13 further includes a curved guide rail 10 and a number of bearing sliders 11. The curved guide rail 10 is fixedly connected to the upper end of the vehicle body 1, and a number of bearing sliders 11 are respectively connected to the upper end of the curved guide rail 10 in a sliding manner. The bearing sliders 11 are rotatably connected to the lower end of the inner door 4. When the inner door 4 moves to the corner of the L-shaped guide rail 8, the bearing sliders 11 slide on the curved guide rail 10 to prevent the inner door 4 from shifting or shaking, ensuring the smooth movement of the inner door 4.

[0028] In order to reduce the force exerted by the operator when pushing the inner door 4 to open and reduce the labor intensity of the operator, the following features are specifically provided: The protection mechanism 13 further includes two adapter plates 18, two positioning slide rails 15, two adapter tension springs 20 and two telescopic rods 21. The two positioning slide rails 15 are respectively fixedly connected to the side walls of the inner main body 2, two adapter buckles 19 are respectively connected to the two positioning slide rails 15 in a sliding manner, the two adapter plates 18 are respectively fixedly connected to the side walls of the inner main body 2, one end of the two telescopic rods 21 is fixedly connected to the two adapter plates 18, and the other end is fixedly connected to the adapter buckles 19. The two adapter tension springs 20 are respectively sleeved outside the two telescopic rods 21. One end of the adapter tension spring 20 is fixedly connected to the adapter buckle 19, and the other end is fixedly connected to the adapter plate 18. When the operator pushes the inner door 4 to open, the adapter buckle 19 slides on the positioning slide rail 15, and the adapter tension spring 20 is stretched to store elastic potential energy. The telescopic rods 21 play an auxiliary supporting and guiding role. Under the elastic force of the adapter tension spring 20, the force exerted by the operator to push the inner door 4 can be reduced, and the labor intensity can be lowered.

[0029] In order to achieve that during the opening process of the inner door 4, the top cover 37 provided at the upper end of the inner main body 2 flips downward to cover the upper end of the inner main body 2, and during the closing process of the inner door 4, the top cover 37 provided at the upper end of the inner main body 2 flips upward to open the upper end of the inner main body 2, the following features are specifically provided: A positioning frame 39 is fixedly connected to the upper end of the inner main body 2. The protection mechanism 13 further includes a pushing rack 14, a pushing gear 16 and a transfer gear 17. The pushing rack 14 is fixedly connected to the transfer buckle plate 19 close to the positioning frame 39. The pushing gear 16 is rotatably connected to the side wall of the positioning frame 39 and meshes with the pushing rack 14. The transfer gear 17 is rotatably connected to the positioning frame 39 and meshes with the pushing gear 16. The transfer gear 17 is fixedly connected to one end of the top cover 37 close to the positioning frame 39. When the inner door 4 is opened, the movement of the transfer buckle plate 19 drives the pushing rack 14 to move. The pushing rack 14 meshes with the pushing gear 16, and then drives the transfer gear 17 to rotate. The transfer gear 17 is fixedly connected to the top cover 37, so as to realize the downward flipping of the top cover 37 to cover the upper end of the inner main body 2. When the inner door 4 is closed, the movement is reversed, and the top cover 37 flips upward to open the upper end of the inner main body 2.

[0030] In order to ensure that after the inner door 4 is opened, the inner door 4 can be clamped without external force, and prevent the inner door 4 from opening by itself under the action of the transfer tension spring 20, the following features are specifically set: The protection mechanism 13 further includes two positioning top plates 34, two limiting bottom plates 35 and two abutting springs 36. The two positioning top plates 34 slide on the outer wall of the inner main body 2 respectively. The two limiting bottom plates 35 are respectively arranged beside the two positioning top plates 34. The limiting bottom plates 35 are fixedly connected to the outer wall of the inner main body 2. The two limiting inclined rods 33 are respectively slidably connected to the two positioning top plates 34 and the two limiting bottom plates 35. The two abutting springs 36 are respectively sleeved outside the two limiting inclined rods 33. One end of the abutting spring 36 is fixedly connected to the positioning top plate 34, and the other end is fixedly connected to the limiting bottom plate 35. After the inner door 4 is opened, when the limiting inclined rod 33 abuts against the transfer buckle plate 19, the limiting inclined rod 33 will push the positioning top plate 34 towards the limiting bottom plate 35. Subsequently, the limiting inclined rod 33 is reset under the action of the abutting spring 36 and clamps the transfer buckle plate 19, preventing the inner door 4 from opening by itself under the action of the transfer tension spring 20, and ensuring the safety and stability of the equipment during the processing process.

[0031] In order to realize that when the door is opened, when the electromagnet 32 is started, it will drive the limiting inclined rod 33 to move away from the transfer buckle plate 19, the following features are specifically set: The protection mechanism 13 also includes two push-pull shafts 26, two reset racks 28, two reset gears 29 and two retreat racks 30. The two push-pull shafts 26 are respectively slidably arranged on both sides of the inner main body 2. The two reset racks 28 are respectively fixedly connected to one end of the two push-pull shafts 26 close to the two limiting inclined rods 33. One side of the two reset gears 29 is rotatably connected to the dust cover 38, and the other side is rotatably connected to the side wall of the inner main body 2. The two reset gears 29 are respectively meshed with the two reset racks 28, and the two retreat racks 30 are respectively fixedly connected to the two limiting inclined rods 33. The two retreat racks 30 are respectively meshed with the two reset gears 29. The push-pull shaft 26 is the input end of the protection mechanism 13. After the electromagnet 32 ​​is started, the push-pull shaft 26 will slide and drive the reset rack 28 to move (the specific movement process will be described in detail later), the reset rack 28 is engaged with the reset gear 29, and the reset gear 29 is engaged with the retreat rack 30, thereby driving the limiting inclined rod 33 to move away from the transfer buckle plate 19, thereby unlocking the transfer buckle plate 19.

[0032] In order to ensure that the two push-pull shafts 26 can move toward the opening direction of the inner body 2 when the door is closed, and to ensure that the reset rack 28 can drive the limiting inclined rod 33 to avoid the transfer buckle plate 19 when it moves subsequently, the following features are also set: The protection mechanism 13 also includes two positioning side plates 24, two reset springs 25 and a number of shaft seats 27. The several shaft seats 27 are arranged in an array at equal intervals along the outer wall of the inner main body 2. The shaft seats 27 are fixedly connected to the outer wall of the inner main body 2. The two push-pull shafts 26 are respectively slidably connected to the several shaft seats 27. The two reset springs 25 are respectively sleeved on the outside of the two push-pull shafts 26. The two positioning side plates 24 are respectively fixedly connected to one end of the two reset springs 25 away from the limiting inclined rod 33. The ends of the two reset springs 25 close to the limiting inclined rod 33 are fixedly connected to the adjacent shaft seats 27. The two auxiliary magnets 23 are respectively fixedly connected to the two positioning side plates 24. When closing the door, since the electromagnet 32 ​​is closed, the attraction between the electromagnet 32 ​​and the auxiliary magnet 23 is terminated. Under the action of the reset spring 25, the push-pull shaft 26 slides on the shaft seat 27. At this time, the push-pull shaft 26 moves toward the opening direction of the inner main body 2, so that the reset rack 28 can drive the limiting inclined rod 33 to avoid the adapter buckle plate 19 during subsequent movement.

[0033] In order to facilitate the movement of the transfer buckle plate 19 when the inner door 4 moves, the following features are also specifically provided: The protection mechanism 13 further includes two retraction pallets 31, which are respectively fixedly connected to two adapter buckles 19. A concave groove is formed on the side of the adapter buckle 19 close to the inner door 4, and the adapter buckle 19 is clamped to the side of the inner door 4. When the inner door 4 moves, the retraction pallet 31 is fixedly connected to the adapter buckle 19, and the adapter buckle 19 is clamped to the side of the inner door 4 through the concave groove. When the inner door 4 moves, the inner door 4 can stably drive the adapter buckle 19 to move synchronously, ensuring the coordinated operation of the entire protection mechanism 13.

[0034] It should be noted that from the actual operation, the clamping of the adapter buckle 19 to the inner door 4 is not a simple planar fit, but an interference fit through a concave groove design, so that the side of the inner door 4 is always constrained by the concave groove during the deflection process. Even when the inner door 4 needs to be deflected by 90° during the opening or closing process, the clamped part of the adapter buckle 19 to the side of the inner door 4 can still be closely matched to ensure that the adapter buckle 19 follows the movement of the inner door 4. That is, when the depth and width of the concave groove are reasonably designed and can ensure the normal movement of the inner door 4, the retraction pallet 31 provides sufficient clamping space for the rotation of the inner door 4, ensuring a stable connection relationship between the two in various states, and then realizing the function of the inner door 4 driving the adapter buckle 19 to move, guaranteeing the normal operation of the entire device.

[0035] The working principle of this device is as follows: when the boring and milling machine 12 needs to load and unload materials and the operator needs to open the door, the electromagnet 32 stops operating, and the main magnet 22 and the auxiliary magnet 23 are disengaged from the electromagnet 32. The operator pulls the door handle 7 to drive the outer door 5 and the inner door 4 to move. Since the outer door 5 and the inner door 4 are hinged by hinges, it can maximize the protection of the workpiece rotation diameter and prevent interference. The movement of the inner door 4 drives the adapter buckle 19, which is positioned by the limiting diagonal rod 33 to prevent the door body from self-resetting during processing.

[0036] During the movement, the pulley 9 at the upper end of the inner door 4 rolls in the wheel groove of the L-shaped guide rail 8 to ensure the movement direction of the inner door 4; several bearing sliders 11 at the lower end of the inner door 4 slide along the curved guide rail 10 to prevent the inner door 4 from offsetting at the corner. The transfer tension spring 20 can reduce the force required for the operator to open the door and reduce the labor intensity of the operator.

[0037] When the door is opened, the transfer buckle plate 19 drives the pushing rack 14, causing the pushing gear 16 and the transfer gear 17 to rotate, realizing the flipping and covering of the top cover 37; when the door is closed, the operation is reversed. When the inner door 4 is opened, under the action of the abutting spring 36, the positioning top plate 34 clamps the transfer buckle plate 19 through the limiting inclined rod 33. When the electromagnet 32 is activated, the electromagnet 32 will drive the auxiliary magnet 23 to attract with it by magnetic force. At this time, the push-pull shaft 26 drives the reset rack 28, and the limiting inclined rod 33 moves to unlock through the reset gear 29. When the operator pushes the inner door 4 and the outer door 5 to move until the two output ends of the electromagnet 32 are respectively adsorbed with the main magnet 22 and the auxiliary magnet 23, because during this process, the opening width of the inner main body 2 is increased, and since there is no cross beam at the feeding port of the inner main body 2, the operator can freely hoist the workpiece into the inner main body 2, so as to facilitate the machining of the workpiece by the boring and milling machine 12.

[0038] When the door is closed, due to the interruption of the magnetic force between the electromagnet 32 and the auxiliary magnet 23, the reset tension spring 25 pushes the push-pull shaft 26, allowing the limiting inclined rod 33 to avoid the transfer buckle plate 19. The inner door 4 drives the transfer buckle plate 19 to move through the retraction clamping plate 31, and all components work together to complete a series of operations such as opening the door, loading materials, machining, and closing the door of the equipment.

[0039] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
