Description

Technical Field

[0001] The present invention relates to the technical field of machine tool processing, in particular to a power hidden dust removal mechanism for a bed, a laser cutting machine and a method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Laser cutting uses invisible beams of light to replace traditional mechanical cutting tools. It offers high precision, fast cutting speeds, unlimited cutting patterns, automatic layout and material savings, smooth cuts, and low processing costs, and is gradually replacing traditional metal cutting equipment. However, the laser cutting process generates significant amounts of metal dust and smoke. These pollutants not only affect cutting quality but also pose health risks to operators and pollute the workshop environment. Therefore, dust removal mechanisms are being added to eliminate these pollutants.

[0004] At present, the dust removal mechanism usually includes a dust removal fan. When the dust removal fan works, the dust generated by cutting is sucked into the dust removal channel. At present, a partitioned dust removal mechanism is set at the bed. The partitioned dust removal mechanism includes a fixed plate and a movable plate. A slot is set on the side of the fixed plate. The movable plate is located in the slot. The movable plate is connected to the driving power source. The driving power source is placed on the side of the bed close to the cutting mechanism. In this way, sparks generated during the cutting process can easily damage the driving power source, and dust also accumulates on the driving end of the driving power source, which can easily affect the normal use of the driving power source. This requires frequent maintenance, which has high maintenance costs. In addition, the external driving power source takes up a large space, the circuit connection is also relatively complicated, and it is placed outside the bed, which requires bending the circuit, making the external circuit easy to be damaged.

[0005] In addition, the movable plate and the fixed plate are installed through a card slot, and the contact between the two is surface contact. The larger the card contact surface, the greater the resistance; dust particles are easily accumulated in the card slot to cause obstruction, affecting the normal opening and closing of the air outlet.

[0006] Of course, other machine tool processing equipment may also face the above problems. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a powered hidden dust removal mechanism for a bed, in which the driving components are built into the side walls of the bed, effectively protecting the driving components, ensuring the service life of the driving components, and reducing the maintenance rate and maintenance costs.

[0008] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0009] A powered hidden dust removal mechanism for a bed, comprising a dust removal fan and a partitioned dust removal plate. The dust removal fan is installed on the bed, and a dust removal channel is formed in a channel inside the side wall of the bed.

During the sliding process of the sliding member relative to the partitioned dust removal plate, the window of the sliding member, the window of the dust removal channel, and the dust removal channel are connected for dust removal.

[0010] The above-mentioned powered hidden dust removal mechanism for the bed further includes a protective plate to cover the driving component in order to further prevent sparks generated by cutting from damaging the driving component and to prevent excessive dust from falling on the driving component. One end of the protective plate is fixed to the side wall of the bed, and the protective plate is tilted to prevent sparks generated by cutting from damaging the driving component.

[0011] As described above, a powered hidden dust removal mechanism for a bed is provided, wherein the sliding part is placed on one side of the partition dust removal plate, the connecting part is provided on the upper and lower sides of the sliding part, the connecting part is provided perpendicularly or intersectingly with the partition dust removal plate, the height of the sliding part is less than the height of the partition dust removal plate, the connecting part is provided with a baffle, part of the baffle is placed on the outside of the sliding part, and the distance between the baffle and the partition dust removal plate is set to ensure the sliding of the sliding part relative to the partition dust removal plate.

[0012] As described above, a powered hidden dust removal mechanism for a bed is provided, wherein the connecting member is provided with a spacer sleeve in an annular direction, and the baffle is placed on the outside of the spacer sleeve. The spacer sleeve is a circular ring-shaped spacer sleeve, and the outer surface of the spacer sleeve contacts the sliding member, which is beneficial to further reduce the resistance of the sliding member when sliding.

[0013] In the above-mentioned power hidden dust removal mechanism for a bed, the connecting member is a bolt, and an elastic pad and a flat pad are provided between the bolt and the baffle, and the elastic pad is provided close to the bolt head.

[0014] As described above, a powered hidden dust removal mechanism for a bed is provided, wherein the window of the partition dust removal plate is a first window, and the first window is provided in multiple locations. The window of the sliding member is a second window, and a baffle is provided between two adjacent second windows in the sliding member. The width of the baffle is adapted to the width of the first window. When the sliding member slides relative to the partition dust removal plate, the dust removal channel is closed when the baffle blocks the first window.

[0015] As described above, a powered hidden dust removal mechanism for a bed, the upper side or the lower side of the partition dust removal plate is bent to form a first bending section, the first bending section of the partition dust removal plate supports the driving component, the upper side or the lower side of the sliding part is bent to form a second bending section, and the second bending section is connected to the driving end of the driving component.

[0016] In the above-mentioned powered hidden dust removal mechanism for a bed, the second bending section is placed on one side of the first bending section, and one side of the second bending section is L-shaped to facilitate connection with the driving end of the driving component.

[0017] In a second aspect, the present invention provides a laser cutting machine, comprising the aforementioned powered hidden dust removal mechanism for a bed.

[0018] In a third aspect, the present invention further provides a method for operating a power hidden dust removal mechanism for a bed, including the following contents:

[0019] The dust removal fan is installed on the bed, and the channel inside the side wall of the bed forms a dust removal channel, and the air inlet of the dust removal fan is connected to the dust removal channel;

[0020] The driving components are placed inside the side wall of the bed through a partition dust removal plate, and the partition dust removal plate is fixedly connected to the inner surface of the side wall of the bed;

[0021] The sliding member is supported by the connecting member at the partition dust removal plate, and the sliding member is connected to the driving end of the driving component;

[0022] During the sliding process of the sliding member relative to the partition dust removal plate, the window of the sliding member, the window of the dust removal channel, and the dust removal channel are connected to perform dust removal.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1) In the present invention, the partitioned dust removal plate supports the driving component, and the driving component is placed in the side wall of the bed. The space inside the side wall of the bed is used to accommodate the driving component, fully protecting the driving component, avoiding sparks generated by cutting to damage the driving component, avoiding damage to the driving component, and avoiding dust falling into the driving part of the driving component as much as possible, reducing the number of maintenance times, and helping to control maintenance costs; the driving component is not arranged on the inner side of the bed, and will not occupy the internal space of the bed. The relevant circuit can be arranged along the internal space of the side wall of the bed, while protecting the circuit, effectively avoiding circuit bending and avoiding circuit damage.

[0025] 2) In the present invention, the partition dust removal plate is provided with a connecting part, which movably supports the sliding part. The contact between the connecting part and the sliding part is line contact, which reduces the resistance of the sliding part during the sliding process and ensures the smooth sliding of the sliding part relative to the partition dust removal plate. Moreover, the form of line contact avoids the accumulation of dust particles compared with the existing slot structure and effectively avoids jamming.

[0026] 3) In the present invention, a protective plate is also provided on the side wall of the bed. The protective plate is tilted to cover the driving component. After the driving component is moved inward to the side wall of the bed, the installation convenience of the driving component must also be considered. After installation, the maintenance problem must also be considered. The setting of the protective plate avoids encapsulating the driving component inside the side wall of the bed, which facilitates the installation and maintenance of the driving component. During the processing, it can also effectively prevent the sparks generated by cutting from flying to the driving component, and can also play a certain dust-proof role.

[0027] 4) The connecting member structure in the present invention is reasonably arranged. The connecting member is placed on the upper and lower sides of the sliding member, and a baffle is arranged at the connecting member. This is equivalent to forming a card slot to limit the sliding member, but it is different from the card slot, because the contact formed between the card slot and the sliding member is surface contact, and the connecting member and the partition dust removal plate are arranged vertically or intersectingly, which effectively ensures that the contact formed between the connecting member and the sliding member is line contact, which is beneficial to the sliding of the sliding member relative to the partition dust removal plate and reduces sliding resistance.

[0028] 5) The partition dust removal plate and sliding member structures in the present invention are reasonably arranged. The partition dust removal plate is provided with a first bending section to support the driving component, and the whole is also convenient for connection with the side wall of the bed. The sliding member is also provided with a second bending section, which is convenient for connection with the driving end of the driving component through the second bending section.

[0037] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0038] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise clearly indicated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprising" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations;

[0039] As introduced in the background technology, in the prior art, the driving power source of the bed dust removal mechanism is placed on the outside of the bed side wall, which has the problems of occupying a large space, being easily damaged by sparks, and dust accumulation affecting the normal use of the driving power source. In order to solve the above technical problems, the present invention proposes a hidden power dust removal mechanism for the bed.

[0040] Example 1

[0041] In a typical embodiment of the present invention, reference is made to Figure 1 and Figure 4As shown, a powered hidden dust removal mechanism for a bed includes a dust removal fan and a partition dust removal plate 4. The dust removal fan is installed on the bed 1, and the inner channel of the bed side wall forms a dust removal channel. The dust removal fan and the partition dust removal plate 4 are set at a distance. The partition dust removal plate 4 is installed at the opening on the inner surface of the side wall of the bed 1. The partition dust removal plate 4 includes a window communicating with the dust removal channel. The partition dust removal plate 4 supports the driving component 6, and the driving component 6 is placed in the side wall of the bed 1. The driving end 19 of the driving component 6 is connected to the sliding member 2. The sliding member 2 is also provided with a window. The partition dust removal plate is provided with a connecting member 5. The connecting member 5 movably supports the sliding member 2. The contact between the connecting member 5 and the sliding member 2 is line contact, so that the sliding member 2 can slide relative to the partition dust removal plate 4. During the sliding process of the sliding member 2 relative to the partition dust removal plate 4, the window of the sliding member, the window of the dust removal channel, and the dust removal channel are connected for dust removal.

[0042] It should be noted that, usually for some mechanical processing equipment, the side wall of the bed 1 has a set thickness, and the inside of the side wall of the bed is hollow, so some lines can be routed. Therefore, in this embodiment, the driving component utilizes the internal space of the side wall of the bed, rather than being placed outside the side wall of the bed, that is, the driving component 6 is arranged on the inside of the bed 1, and the side wall of the bed 1 is used to protect the driving component 6, and dust is avoided as much as possible from falling into the driving part of the driving component, thereby reducing the number of maintenance times. In addition, the internal space of the side wall of the bed can be used to lay relevant lines, which can effectively avoid bending of the lines while protecting the lines and avoid circuit damage.

[0043] In order to further prevent the sparks generated by cutting from damaging the driving components and to prevent excessive dust from falling on the driving components, the dust removal mechanism also includes a protective plate 3, which covers the driving component 6. The upper end of the protective plate 3 can be removably mounted on the side wall of the bed, and the lower half of the protective plate 3 is tilted to prevent the sparks generated by cutting from damaging the driving components. The formation of a certain space between the protective plate 3 and the driving component 6 is also conducive to the heat dissipation of the driving component.

[0044] Specifically, the protective plate 3 can be a stainless steel plate or other materials. The lower end of the protective plate 3 is set lower than the upper side of the partition dust removal plate, and the lower end of the protective plate 3 is set at a distance from the sliding member.

[0045] In this embodiment, the partition dust removal plate 4 is a rectangular plate, and the four corners of the partition dust removal plate 4 are installed on the side wall of the bed 1 by countersunk screws 15. The window of the partition dust removal plate 4 is the first window, and there are multiple first windows. The interval between two adjacent first windows is the distance. The window of the sliding member 2 is the second window. The length and width of the second window are the same as the length and width of the first window. A baffle is set between the two adjacent second windows in the sliding member, and the width of the baffle is adapted to the width of the first window. During the sliding process of the sliding member 2 relative to the partition dust removal plate 4, the dust removal channel is closed when the baffle blocks the first window.

[0046] It should be noted that the reference Figure 2 and Figure 3 As shown, because some of the side walls of the bed are connected together by welding two sections of steel pipes, the height of the partition dust removal plate 4 is adapted to the height of the lower steel pipe, and the middle section of the upper side of the partition dust removal plate is raised and bent to form a first bending section 7. The first bending section 7 is an L-shaped section. The horizontal section of the first bending section is higher than the top side of the partition dust removal plate 4 so that the first bending section can enter the upper steel pipe. The horizontal section of the first bending section of the partition dust removal plate 4 supports the driving component. The driving component 6 is placed horizontally inside the side wall of the bed, and of course it can also be placed inside the side wall of the bed in an inclined manner; the driving component 6 is specifically a driving cylinder, and the driving component has a connector 18 for connecting lines. The driving component 6 can be installed at the first bending section 7 by screws 17;

[0047] The sliding member 2 is a sliding plate, and the upper side of the sliding member 2 is bent to form a second bent section 8. The second bent section 8 is an L-shaped section. Moreover, the first bent section 7 and the second bent section 8 are staggered. Considering that the second bent section is connected to the driving end 19 of the driving component via a cylindrical head screw 6, the horizontal section of the second bent section 8 is higher than the horizontal section of the first bent section 7. Considering that the second bent section 8 needs to be connected to the driving end 19 of the driving component, the second bent section 8 is placed on one side of the first bent section 7. One side of the horizontal section of the second bent section 8 is bent upward to form an L-shape, and the upward bent side of the second bent section 8 is connected to the driving end 19 (driving plate) of the driving component.

[0048] It is easy to understand that the sliding member 2 is placed on the side of the partition dust removal plate 4 away from the side wall of the bed 1, and the connecting member 5 is provided on the upper and lower sides of the sliding member. Two connecting members are provided on the upper and lower sides of the sliding member 2. The spacing between the two connecting members 5 on the upper side is set, and the spacing between the two connecting members on the lower side is set. The connecting member 5 is perpendicular to the partition dust removal plate 4. The height of the sliding member 2 is less than the height of the partition dust removal plate to ensure the setting of the sliding member 2. The connecting member is provided with a baffle 12, and part of the baffle 12 is placed on the outside of the sliding member. The spacing between the baffle 12 and the partition dust removal plate 4 is set to ensure the sliding of the sliding member relative to the partition dust removal plate. The baffle 12 is provided at the connecting member 5, which is equivalent to forming a slot to limit the sliding member, but is different from the slot, because the contact formed between the slot and the sliding member is surface contact, while the connecting member 5 and the partition dust removal plate 4 are vertically arranged, effectively ensuring that the contact formed between the connecting member and the sliding member is line contact, which is beneficial to the sliding of the sliding member relative to the partition dust removal plate and reduces the sliding resistance.

[0049] Specifically, the connecting member 5 is a bolt, and the baffle 12 is sleeved on the screw of the bolt 9. An elastic pad 10 and a flat pad 11 are provided between the bolt head and the baffle. The elastic pad 10 is arranged close to the bolt head. The connecting member 5 is provided with a spacer 13 in an annular direction, and the baffle 12 is placed on the outside of the spacer away from the side wall of the bed. The spacer 13 is a circular spacer, and the outer surface of the spacer 13 contacts the sliding member 2, which is conducive to further reducing the resistance of the sliding member when sliding. The arc surface of the spacer also avoids the accumulation of dust particles and prevents jamming.

[0050] In the device provided by this embodiment, the driving component 6 is placed in the side wall of the bed, and the space inside the side wall of the bed is used to accommodate the driving component, thereby fully protecting the driving component 6, avoiding sparks generated by cutting from damaging the driving component, avoiding damage to the driving component, and avoiding dust from falling into the driving part of the driving component as much as possible, reducing the number of maintenance times, which is beneficial to controlling maintenance costs. In conjunction with the setting of the protective plate, it further avoids sparks from damaging the driving component, avoids dust accumulation, and is beneficial to the heat dissipation of the driving component; the connecting part movably supports the sliding part, and the contact between the connecting part and the sliding part is line contact, which reduces the resistance of the sliding part during sliding and ensures the smooth sliding of the sliding part relative to the partition dust removal plate. Moreover, the form of line contact avoids the accumulation of dust particles compared to the existing slot structure and effectively avoids jamming.
