Description

Technical Field

[0001] This utility model belongs to the technical field of vertical machining centers and their accessories, and in particular relates to a vertical machining center with a filtration structure. Background Technology

[0002] A vertical machining center is a multi-functional CNC machine tool with its spindle axis perpendicular to the worktable. In addition to machining machinery, it also includes auxiliary devices, such as cooling and filtration structures. The filtration structure is further divided into liquid filtration and gas filtration structures, with the gas filtration structure used to filter the fumes generated during machining.

[0003] Chinese patent application CN219504263U discloses a vertical machining center with a fume filtration structure, including a vertical machine tool. The bottom of the machine tool is connected to a load-bearing base, and a worktable is connected inside the machine tool. Fixing blocks are installed on the inner walls of both sides of the machine tool, and a connecting block is provided at the front end of each fixing block. Screws are installed between the fixing blocks and the connecting blocks, and the fixing blocks and connecting blocks are fixedly connected by screws. This invention, through the cooperation between a filter screen and a dust extraction motor, enables the vertical machine tool to filter the fumes generated during parts processing, preventing operators from inhaling the fumes for extended periods and thus improving operator safety.

[0004] The aforementioned vertical machining center with a flue gas filtration structure has fixed blocks installed in the middle of the inner walls on both sides of the vertical machine tool. A connecting block is located on the outer side of the fixed blocks. The flue gas filtration structure is installed within the space enclosed by the fixed blocks and the connecting blocks, meaning it is located inside the vertical machine tool. The filter screen in the flue gas filtration structure is a consumable part, requiring replacement or maintenance after use. However, because the flue gas filtration structure is located inside the vertical machine tool, it is impossible to perform maintenance or replacement of the filter screen during machine operation. Furthermore, the fixed blocks and connecting blocks used to house the flue gas filtration structure are metal structures. The flue gas filtration structure mainly consists of inlet and outlet pipes, a dust extraction motor, and a filter screen. When the dust extraction motor operates, it absorbs gas from the vertical machining center through the inlet pipe. However, the dust extraction motor generates significant vibration during operation. Since the dust extraction motor is directly mounted on the fixed blocks, this vibration is directly transmitted to the vertical machining center, affecting its stability during operation and generating considerable noise. To address these issues, we provide a vertical machining center with a filtration structure. Utility Model Content

By using an external filter box and mounting components for installing the filter box, not only can the vibration generated during operation be reduced, but also the noise can be weakened. The sealing components facilitate the disassembly and assembly of the filter screen inside the filter box, thus solving the problems of the aforementioned vertical machining center with a flue gas filtration structure.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] The present invention is further configured such that a control box is installed at the center of the upper side wall of the machining center body, a safety door is installed on the front side wall of the machining center body, and a bracket is also provided at the bottom of the machining center body.

[0009] The present invention is further configured such that air plates are provided at both ends of the filter box, and the filter box is connected to an air pipe through the air plates, and the other end of the air pipe is connected to the machining center body.

[0010] The present invention is further configured such that a slot is provided on the upper side wall of the air inlet end of the filter box, the filter screen is inserted into the slot, and the sealing component is disposed on the upper part of the slot.

[0011] The present invention is further configured such that the outer peripheral sidewall of the rotating plate is fitted with the inner wall of the slot, and a handle is fixedly installed on the upper sidewall of one end of the rotating plate, and a rubber plate is adhered to the bottom sidewall of the rotating plate.

[0014] The present invention is further configured such that the base is connected to the bottom side wall of the filter box through the sound-absorbing cotton board in the mounting groove, and the first upright plate is connected to the side wall at the corner of the filter box through the second upright plate of the same material as the sound-absorbing cotton board, and the first upright plate and the sound-absorbing cotton board are configured as an integral structure.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model includes a filter box, an air pipe, a suction fan, and an installation assembly. The filter box is located on the outside of the machining center body and is connected to the internal environment of the machining center body through the air pipe. The filter box also contains a suction fan, which accelerates the gas flow, allowing the gas to flow rapidly between the machining center body and the filter box through the air pipe. An installation assembly is located at the bottom of the filter box, allowing it to be fixedly mounted on the side wall of the machining center body. The installation assembly includes a connecting frame fixed to the outer wall of the machining center body and a base on the bottom side wall of the filter box. The base is fixedly connected to the connecting frame. An installation groove is provided on the upper side wall of the base, and upright plates are provided at the four corners of the installation groove. The interior of the installation groove is filled with sound-absorbing cotton boards. At each of the four corners of the sound-absorbing cotton board, there is a second upright plate. The second upright plate is attached to the inner side wall of the first upright plate and is made of the same material as the sound-absorbing cotton board. That is, the bottom side wall of the filter box is connected to the base through the sound-absorbing cotton board, and the first upright plate is connected to the side wall of the filter box at the corner through the second upright plate, which is made of the same material as the sound-absorbing cotton board. When the suction fan in the filter box is working, the vibration generated by it will be transmitted from the filter box to the sound-absorbing cotton board. This vibration is greatly weakened before it is transmitted to the machining center body through the base and connecting frame. This also greatly reduces the interference of vibration to the machining center body during operation. At the same time, the sound-absorbing cotton board has multiple tiny holes. When noise is transmitted from the filter box to the sound-absorbing cotton board, the noise passes through them, which greatly consumes energy and achieves a noise reduction effect.

[0017] 2. This utility model, by setting up a filter box, a filter screen, and a sealing assembly, has a slot on the upper side wall of the air inlet side of the filter box, into which the filter screen is inserted. A sealing assembly is also provided above the filter screen and inside the slot. The sealing assembly includes a rotating plate disposed within the slot. A handle is installed on the upper side wall of the rotating plate, and a rubber plate is adhered to its bottom side wall. The rotating plate abuts against the upper side wall of the filter screen via the rubber plate. A rotating shaft is inserted into the other end of the rotating plate. Return springs are provided at both ends of the rotating shaft, and bushings are sleeved on the outer side of the return springs. That is, the rotating shaft is connected to the bushings via the return springs, and the bushings are embedded in the two side walls of the slot. When in use, hold the handle and pull upwards to apply upward force to the rotating plate. Due to the restriction of the pivot, the rotating plate can only rotate around the pivot. At the same time, the return spring is also subjected to reverse torque, which creates pressure on the return spring. Since the pulling force is greater than the torque of the return spring itself, the rotating plate will be opened by rotation, allowing you to remove the filter screen underneath. After replacing the filter screen, simply release the handle. At this time, the pressure on the return spring will disappear, restoring it to its initial state. This will push the pivot and the rotating plate to rotate in the opposite direction until they close back into the slot, forming a seal. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 1-4 This utility model is a vertical machining center with a filtration structure, including a machining center body 1 and a filtration mechanism 5 disposed next to the machining center body 1. The filtration mechanism 5 is mainly a filter box 501. The filter screen 501d inside the filter box 501 filters the gas entering it, while the suction fan 501c inside the filter box 501 is used to accelerate the gas flow rate, so that the gas flows quickly between the machining center body 1 and the filter box 501 through the air pipe 502.

[0029] Specifically, a control box 2 is provided at the upper end of the machining center body 1, a safety door 3 is installed on the front side wall, and a bracket 4 is provided at the bottom. The filter mechanism 5 is located on the side of the machining center body 1. The filter mechanism 5 includes a mounting assembly 504 fixed on the side wall of the machining center body 1 and a filter box 501 located above the mounting assembly 504.

[0030] The mounting assembly 504 includes a connecting frame 504b fixed to the side wall of the machining center body 1, and a base 504a fixedly provided at the other end of the connecting frame 504b. The upper side wall of the base 504a is provided with a mounting groove 504c, and upright plates 504d are provided at the four corners of the mounting groove 504c. The mounting groove 504c and the upright plates 504d can stabilize the filter box 501 placed on the base 504a.

[0031] Furthermore, the interior of the mounting groove 504c is also equipped with a sound-absorbing cotton board 504e, and the four corners of the sound-absorbing cotton board 504e are also equipped with a second upright plate 504f. The second upright plate 504f and the sound-absorbing cotton board 504e are integrated into one structure. That is, the base 504a is connected to the bottom side wall of the filter box 501 through the sound-absorbing cotton board 504e in the mounting groove 504c, and the first upright plate 504d is connected to the side of the filter box 501 through the second upright plate 504f, which is made of the same material as the sound-absorbing cotton board 504e. The sound-absorbing cotton board 504e can not only play a role in buffering and shock absorption, but also reduce noise.

[0032] Air plates 501a are provided on both sides of the filter box 501, and the filter box 501 is connected to the air pipe 502 through the air plates 501a. The other end of the air pipe 502 is connected to the internal environment of the machining center body 1. A suction fan 501c is also installed inside the filter box 501. An equipment door 503 is also installed on the right outer wall of the filter box 501. The electrical components inside the filter box 501 can be inspected and maintained through the equipment door 503.

[0033] The operation process of this embodiment is as follows: In use, the filter box 501 is placed on the sound-absorbing cotton plate 504e of the base 504a. That is, the bottom side wall of the filter box 501 is connected to the base 504a through the sound-absorbing cotton plate 504e, and the first upright plate 504d is connected to the side wall of the filter box 501 at the corner through the second upright plate 504f of the same material as the sound-absorbing cotton plate 504e. When the suction fan 501c in the filter box 501 is working, the vibration generated by it will be transmitted from the filter box 501 to the sound-absorbing cotton plate 504e. This vibration is greatly weakened by the sound-absorbing cotton plate 504e before it is transmitted to the machining center body 1 through the base 504a and the connecting frame 504b. This also greatly reduces the interference of vibration to the machining center body 1 during operation. At the same time, the sound-absorbing cotton plate 504e has multiple small holes. When noise is transmitted from the filter box 501 to the sound-absorbing cotton plate 504e, the noise passes through them, which greatly consumes energy and achieves the effect of noise reduction.

[0034] Example 2

[0035] Please see Figure 5-6 Based on Embodiment 1, a filter screen 501d and a sealing component 505 are also provided. The filter screen 501d can filter the gas entering the filter box 501 and then discharge it back into the internal environment of the machining center body 1. The sealing component 505 is also provided above the filter screen 501d. When the sealing component 505 is not under force, it can automatically close above the filter screen 501d to achieve the effect of sealing and stabilizing the filter screen 501d. When it is under force, it can be opened to facilitate the removal of the filter screen 501d inside.

[0036] Specifically, a slot 501b is provided on the upper side wall of the air inlet end of the filter box 501, and a filter screen 501d is inserted into the slot 501b. A sealing component 505 is also provided above the filter screen 501d and inside the slot 501b.

[0037] Furthermore, the sealing assembly 505 includes a rotating plate 505a disposed in the slot 501b. A handle 505b is fixedly disposed on the right end of the upper side wall of the rotating plate 505a. The handle 505b is used for holding, making it easier to lift and rotate the rotating plate 505a. A rubber plate 505c is also attached to the bottom side wall of the rotating plate 505a, that is, the rotating plate 505a is connected to the upper side wall of the filter screen 501d through the rubber plate 505c.

[0038] The other end of the rotating plate 505a is also connected to a rotating shaft 505d, and the two ends of the rotating shaft 505d are also fitted with return springs 505e. The outer side of the return spring 505e is also fitted with a bushing 505f. That is, the rotating shaft 505d is connected to the bushing 505f through the return spring 505e. At the same time, the bushing 505f is also embedded in the side walls of both ends of the slot 501b.

[0039] The operation process of this embodiment is as follows: When in use, hold the handle 505b and pull it upwards, so that the rotating plate 505a is subjected to an upward pulling force. Due to the restriction of the rotating shaft 505d, the rotating plate 505a can only rotate around the rotating shaft 505d. At the same time, the return spring 505e is also subjected to a reverse torque, which generates a pressure force on the return spring 505e. At this time, since the pulling force is greater than the torque of the return spring 505e itself, the rotating plate 505a will be opened by rotation, so that the filter screen 501d below can be taken out. After the filter screen 501d is replaced, simply release the handle 505b. At this time, the pressure force on the return spring 505e disappears and returns to the initial state, which can push the rotating shaft 505d and the rotating plate 505a to rotate in the opposite direction until they close into the slot 501b again to form a seal.
