Description

Technical Field

[0001] The present application relates to the field of machine tool dust removal, and in particular to a dust suction mechanism and a dust suction device for a spindle head of a composite material machining center. Background Art

[0002] When machine tools process aviation composite materials, a large amount of composite material powder will be generated. The composite material dust contains carbon fiber, which not only affects human health, but also poses a risk of dust explosion, which needs to be effectively removed.

[0003] The Chinese patent with the authorization announcement number CN115338674A discloses a dust removal system, dust removal method and machine tool for a five-axis aviation composite material processing machine tool. In the comparative document, the rotary transfer structure includes a Z-axis slide connection and a C-axis motion arm connection. The C-axis motion arm connection is axially connected to the Z-axis slide connection and can rotate relative to the same rotation axis. A sealed transfer chamber is formed between the Z-axis slide connection and the C-axis motion arm connection. The vacuum generator connection port sucks the dust generated during the prop processing into the sealed transfer chamber formed between the Z-axis slide connection and the C-axis motion arm connection, and then sucks it into the vacuum generator connection port.

[0004] However, the Z-axis slide table connector and the C-axis motion arm connector are both L-shaped structures, and the sliding sealing of the sealed transfer chamber formed therein is poor, which weakens the adsorption effect of the negative pressure in the sealed transfer chamber on dust, thereby reducing the dust collection effect at the spindle head. Summary of the invention

[0005] In order to improve the poor sliding sealing of the sealed transfer chamber, weaken the adsorption effect of the negative pressure in the sealed transfer chamber on dust, and reduce the dust suction effect of the spindle head, the present application provides a dust suction mechanism and a dust suction device for the spindle head of a composite material machining center.

[0007] By adopting the above technical solution, when vacuuming the spindle head, a vacuum is generated at the vacuum generator connection port, and then the dust at the spindle head enters the sealed transfer chamber along the vacuum module and the vacuum hose under the adsorption of negative pressure, and then is sucked into the vacuum generator interface to achieve dust collection at the spindle head; when the C-axis motion arm rotates and adjusts its position relative to the Z-axis slide, sliding occurs between the U-box structure and the U-cover structure, so that the sealed transfer chamber remains in a sealed state. Due to the use of the U-box structure and the U-cover structure, a larger contact surface is formed between the two. The larger contact surface helps to disperse the pressure, making the sealing interface more continuous and uniform. At the same time, the design of the U-shaped structure can distribute stress more evenly. The uniform stress distribution not only reduces the possibility of deformation, but also maintains a relatively stable sealing effect during the sliding process, thereby improving the sealing effect of the sealed transfer chamber, enhancing the adsorption effect of the negative pressure in the sealed transfer chamber on dust, and improving the vacuuming effect of the spindle head.

[0019] By adopting the above technical solution, the dust collector sucks in the light dust generated in the processing area through the main dust suction duct and the branch dust suction duct, and then the dust-containing gas enters the dust collector, and then filters the dust, thereby realizing the treatment of light dust; when the spindle head drives the tool to process the composite material, the control part on the branch dust suction duct at the corresponding position is opened, and the branch dust suction duct will perform dust suction treatment on the corresponding area, thereby reducing the reduction of negative pressure caused by the opening of other branch dust suction ducts, thereby improving the dust suction effect of the branch dust suction duct.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-9 This application is described in further detail.

[0038] On the one hand, an embodiment of the present application discloses a dust suction mechanism for a spindle head of a composite material machining center.

[0039] Reference Figure 1 , Figure 2A dust suction mechanism for the spindle head of a composite material processing center includes a dust suction module 2, a U-shaped cover structure 31 fixedly arranged on the Z-axis slide 11 of the composite material processing machine tool, and a U-shaped box structure 32 fixedly arranged on the C-axis motion arm 12 of the composite material processing machine tool. The composite material processing adopts a five-axis aviation composite material processing machine tool, and the spindle head 14 can move along five axial directions. The processing machine tool has the advantages of flexible movement of the spindle head 14 and high processing accuracy, and can process various processing surfaces on aviation composite materials. The five-axis aviation composite material processing machine tool includes an X-axis slide 15, a Y-axis slide, a Z-axis slide 11, a C-axis motion arm 12, and an A-axis motion arm 13. The spindle head 14 is arranged on the A-axis motion arm 13 with the largest degree of freedom, and the C-axis motion arm 12 is arranged on the Z-axis slide 11 and can rotate around the Z-axis slide 11.

[0040] Reference Figure 1 , Figure 2 The U-shaped cover structure 31 is an annular structure and is fixedly installed on the Z-axis slide 11 by bolts. The opening of the U-shaped cover structure 31 faces the C-axis motion arm 12. The U-shaped cover structure 31 includes a plurality of cover bodies 311. In this embodiment, the number of cover bodies 311 is two. Both ends of the cover body 311 are respectively connected to the two ends of another cover body 311 by bolts, so that the two cover bodies 311 are spliced ​​to form a U-shaped cover structure 31, thereby improving the convenience of installing the U-shaped cover structure 31 on the Z-axis slide 11. The U-shaped box structure 32 is an annular structure and is fixedly installed on the C-axis motion arm 12 by bolts. The opening of the U-shaped box structure 32 is opposite to the opening of the U-shaped cover structure 31, and can be inserted into the inner cavity of the U-shaped cover structure 31 from the opening of the U-shaped cover structure 31. The U-shaped box structure 32 in this embodiment includes two box bodies 321, and the ends of the two box bodies 321 are fixedly connected by bolts so that the two box bodies 321 are spliced ​​into a U-shaped box structure 32, thereby improving the convenience of installing the U-shaped box structure 32 on the C-axis motion arm 12.

[0041] When the U-shaped box structure 32 is inserted into the U-shaped cover structure 31, the U-shaped cover structure 31 and the U-shaped box structure 32 are rotationally sealed and connected, and a sealed transfer chamber 33 is formed between the U-shaped cover structure 31 and the U-shaped box structure 32. A sliding sealing ring 34 is embedded on the side wall of the inner cavity of the U-shaped cover structure 31, and the sliding sealing ring 34 abuts and seals against the outer wall of the U-shaped box structure 32, thereby improving the sealing effect of the sealed transfer chamber 33.

[0042] Reference Figure 1 , Figure 2The top of the U-shaped cover structure 31 is provided with a vacuum generator connection port 35 connected to the sealed transfer chamber 33. The vacuum generator connection port 35 is connected to a vacuum generator through a pipeline, which can make the sealed transfer chamber 33 in a negative pressure state. The dust collection module 2 is arranged at the spindle head 14 on the A-axis motion arm 13. The dust collection module 2 is connected to the sealed transfer chamber 33 through two dust collection hoses 36. The ends of the two dust collection hoses 36 are fixed to the bottom of the U-shaped box structure 32 and are connected to the sealed transfer chamber 33.

[0043] When vacuuming the spindle head 14 , the vacuum generator connection port 35 generates a vacuum, and then the dust at the spindle head 14 enters the sealed transfer chamber 33 along the vacuum module 2 and the vacuum hose 36 under the adsorption of negative pressure, and is then sucked into the vacuum generator connection port 35 to achieve vacuuming of the spindle head 14 .

[0044] When the C-axis moving arm 12 rotates and adjusts its position relative to the Z-axis slide 11, sliding occurs between the U-shaped box structure 32 and the U-shaped cover structure 31, so that the sealed transfer chamber 33 remains sealed. Due to the use of the U-shaped box structure 32 and the U-shaped cover structure 31, a larger contact surface is formed between the two. The larger contact surface helps to disperse the pressure, making the sealing interface more continuous and uniform. At the same time, the design of the U-shaped structure can distribute stress more evenly. The uniform stress distribution not only reduces the possibility of deformation, but also maintains a relatively stable sealing effect during the sliding process, thereby improving the sealing effect of the sealed transfer chamber 33, enhancing the negative pressure in the sealed transfer chamber 33. The adsorption effect of dust, improves the dust absorption effect of the spindle head 14. At the same time, the surface-to-surface contact of the U-shaped structure makes the friction force more evenly distributed, reducing the risk of local wear. During the sliding process, the U-shaped structure can maintain a relatively stable contact interface, thereby extending the service life of the seal.

[0045] Reference Figure 1 , Figure 2The dust suction module 2 in this embodiment includes a dust suction cylinder 21, which is fixedly disposed on the A-axis moving arm 13 and coaxially disposed with the spindle head 14. The ends of the two dust suction hoses 36 are fixedly disposed on the dust suction cylinder 21 and are connected to the inner cavity of the dust suction cylinder 21. The dust collection cylinder 21 is fixedly connected with a telescopic accordion cover 22 on the side facing away from the A-axis moving arm 13, and the telescopic accordion cover 22 is fixedly connected with a flexible strip seat 25 on the side facing away from the dust collection cylinder 21. The flexible strip seat 25 is fixedly provided with a plurality of flexible isolation strips 23 on the side facing away from the telescopic accordion cover 22. The plurality of flexible isolation strips 23 are evenly arranged along the circumference of the flexible strip seat 25. The flexible isolation strips 23 can be made of a variable material with a certain elastic force, such as soft glass strips and hard bristle brushes, so as to better adapt to aviation composite materials with different surfaces and form better isolation between the inside and outside of the flexible isolation strips 23. When the spindle head 14 processes the aviation composite material, the flexible isolation strips 23 can better contact with the surface of the aviation composite material, so that the negative pressure structure of the spindle head and the surface of the aviation composite material form a relatively closed negative pressure dust collection space.

[0046] Reference Figure 1 , Figure 3 A distance adjustment device 24 is provided on the A-axis moving arm 13. The adjustment device in this embodiment is an electric push rod. In other embodiments, it can also be a hydraulic cylinder, a pneumatic cylinder, etc. The output shaft of the electric push rod is fixedly connected to the flexible strip seat 25, and pushes the dust collector 21 to slide along its own axis.

[0047] By controlling the extension and retraction of the distance adjustment device 24, the distance between the dust collection cylinder 21 and the A-axis moving arm 13 can be adjusted. When the distance between the dust collection cylinder 21 and the A-axis moving arm 13 is shortened, the spindle head 14 can be better exposed, thereby facilitating the replacement of the machining tool on the spindle head 14; when the distance between the dust collection cylinder 21 and the A-axis moving arm 13 is extended, the flexible isolation strip 23 can better contact the surface of the aviation composite material, thereby ensuring the sealing of the internal space of the spindle head negative pressure structure and the formation of a high negative pressure environment.

[0048] The implementation principle of the dust suction mechanism of the spindle head of a composite material machining center in the embodiment of the present application is as follows: when the C-axis moving arm 12 rotates and adjusts its position relative to the Z-axis slide 11, sliding occurs between the U-shaped box structure 32 and the U-shaped cover structure 31, so that the sealed transfer chamber 33 remains sealed. Due to the use of the U-shaped box structure 32 and the U-shaped cover structure 31, a larger contact surface is formed between the two. The larger contact surface helps to disperse the pressure, making the sealing interface more continuous and uniform. At the same time, the design of the U-shaped structure can distribute stress more evenly. The uniform stress distribution not only reduces the possibility of deformation, but also maintains a relatively stable sealing effect during the sliding process, thereby improving the sealing effect of the sealed transfer chamber 33, enhancing the negative pressure in the sealed transfer chamber 33. The adsorption effect of dust, improves the dust suction effect of the spindle head 14. At the same time, the surface-to-surface contact of the U-shaped structure makes the friction force more evenly distributed, reducing the risk of local wear. During the sliding process, the U-shaped structure can maintain a relatively stable contact interface, thereby extending the service life of the seal.

[0049] On the other hand, an embodiment of the present application also discloses a dust suction device for a spindle head of a composite material machining center.

[0050] Reference Figure 4 , Figure 5 A composite material processing center spindle head dust suction device, using the composite material processing center spindle head dust suction mechanism, including a workbench 4 arranged on a foundation, two X-direction slide rails 151 of an X-direction slide table 15 are fixedly arranged on the foundation, the workbench 4 is arranged between the two X-direction slide rails 151, and a processing area for placing the composite material to be processed is formed, the foundation is provided with baffles 41 for enclosing the processing area around the processing area, the two X-direction slide rails 151 are provided with two folding plates 42 above the processing area, and the folding plates 42 are located on both sides of the X-direction slide 152 of the X-direction slide table 15 When the X-axis slide 152 slides, one of the folding plates 42 extends and the other folding plate 42 contracts. The folding plates 42 and the baffle plate 41 enclose the processing area. The baffle plate 41 and the folding plate 42 gather dust in a certain area, effectively preventing the dust from spreading further, and forming a good negative pressure in the processing area, which is convenient for dust collection. The dust removal component 5 sucks away light dust and processes it, and the cleaning component 6 cleans and collects heavy dust. In this way, the dust generated during the processing of composite materials can be vacuumed and effectively prevented from causing harm to the staff.

[0051] Reference Figure 4 , Figure 5A dust removal component 5 and a cleaning component 6 are provided on the foundation. The dust is divided into light dust and heavy dust according to the mass of the dust. The dust removal component 5 is used to absorb and process the light dust generated in the processing area. The cleaning component 6 is set in the processing area and is used to clean the heavy dust generated in the processing area.

[0052] The dust removal component 5 sucks away and processes the light dust, and the cleaning component 6 cleans and collects the heavy dust. In this way, the dust generated during the processing of the composite material can be vacuumed and processed, effectively avoiding the harm caused by the dust to the workers.

[0053] Reference Figure 5 , Figure 6 The dust removal assembly 5 in this embodiment includes a dust collector 53, a main dust suction pipe 51, and a sub-dust suction pipe 52. The dust collector 53 is a bag-type dust collector, which is fixedly arranged on the workbench 4. One end of the main dust suction pipe 51 is connected to the air inlet of the dust collector 53, and the rest extends to both sides of the processing area. There are multiple sub-dust suction pipes 52, which are arranged on the main dust suction pipes 51 on both sides of the processing area. Each sub-dust suction pipe 52 is provided with a control component 54. The control component 54 in this embodiment includes a control cylinder 541 controlled by a solenoid valve and a control board 542. The control board 542 is slidably arranged on the X-direction slide rail 151. The control cylinder 541 is fixedly arranged on the X-direction slide rail 151. The output shaft of the control cylinder 541 is fixedly connected to the control board 542, and drives the control board 542 to slide onto or away from the opening of the sub-dust suction pipe 52. One end of each branch dust suction pipe 52 is connected to the main dust suction pipe 51, and the other end passes through the baffle 41 and is fixed on the X-direction slide rail 151. The outlet of the vacuum generator is connected to the dust collector 53 through a pipe, so that the dust generated at the spindle head 14 can enter the dust collector 53 for treatment. The dust collector 53 sucks the light dust generated in the processing area through the main dust suction pipe 51 and the branch dust suction pipe 52, and then the dust-containing gas enters the dust collector 53, and then the dust is filtered, thereby achieving the treatment of light dust.

[0054] Reference Figure 5 , Figure 7 and Figure 8, the number of cleaning components 6 in this embodiment is two groups, and the two groups of cleaning components 6 are respectively arranged along the sliding direction of the X-direction slide 152 and are located between the composite material and the X-direction slide rail 151. The cleaning components 6 in this embodiment include a conveyor belt mechanism 61, a material guide box 62, and a material storage box 63. The workbench 4 is provided with a mounting groove 43 corresponding to the conveyor belt mechanism 61, and the part of the conveyor belt mechanism 61 located in the processing area is located in the mounting groove 43. One end of the material guide box 62 is fixed to the baffle 41 and communicated with the processing area, and the other end extends obliquely upward, and a drop opening 621 is provided at the bottom of the highest point. One end of the conveyor belt mechanism 61 is inserted into the material guide box 62 and extends above the drop opening 621, so that the heavy dust on the conveyor belt mechanism 61 can fall out of the material guide box 62 from the drop opening 621. A plurality of baffles are installed on the conveyor belt of the conveyor belt mechanism 61, which can push the heavy dust on the conveyor belt to move with the conveyor belt. The material holding box 63 is disposed below the material dropping opening 621 so as to collect heavy dust dropped from the conveyor belt mechanism 61 .

[0055] Reference Figure 7 , Figure 8 Each material guide box 62 is provided with a rotating active component 622 and a sealing plate 623. The rotating active component 622 in this embodiment is a rotary cylinder, and in other embodiments it can also be a rotating motor. One end of the sealing plate 623 is fixedly arranged on the output shaft of the rotating active component 622. The rotating active component 622 is used to drive the sealing plate 623 to rotate so that the sealing plate 623 can block the blanking port 621.

[0056] When the dust moves toward the entrance of the dust collecting pipe 52, heavy dust with a larger mass falls onto the conveyor belt mechanism 61. When the composite material processing is completed, the dust collector 53 is closed, and the active member drives the blocking plate 623 to rotate, so that the material drop opening 621 is opened, and then the conveyor belt mechanism 61 drives the heavy dust into the material guide box 62, and unloads at the material drop opening 621, and the heavy dust falls into the material storage box 63, thereby realizing the cleaning and collection of the heavy dust. At other times, the active member 622 is rotated to drive the blocking plate 623 to block the material drop opening 621, thereby effectively preventing dust from leaking from the material drop opening 621.

[0057] Reference Figure 8 , Fig. 9The workbench 4 is provided with multiple sets of closing plates 71 in the processing area, and base rods 72 and driving rods 73 are provided on the opposite side walls of the mounting groove 43. The base rod 72 and the driving rod 73 are both located above the conveyor belt mechanism 61. The driving rod 73 is slidably arranged above the base rod 72, and the base rod 72 is fixedly arranged on the side wall of the mounting groove 43. The multiple sets of closing plates 71 are arranged in the mounting groove 43 along the length direction of the mounting groove 43. Each group of closing plates 71 includes a first plate 711 and a second plate 712. A first rotating shaft 713 and a second rotating shaft 714 are fixedly provided on opposite side walls of the first plate 711 and the second plate 712. The first plate 711 and the second plate 712 can rotate around the first rotating shaft 713 or the second rotating shaft 714. A plurality of sliding grooves 715 are provided on each base rod 72. The first rotating shaft 713 on the first plate 711 and the second plate 712 of the same group is located between the second rotating shaft 714. The first rotating shaft 713 is inserted into the driving rod 73 and rotatably connected. The opposite sides of the first plate 711 and the second plate 712 are fitted with arc surfaces, so that when the first plate 711 and the second plate 712 rotate around the first rotating shaft 713, the first plate 711 and the second plate 712 are in a closed state. The second rotating shaft 714 is inserted into the sliding groove 715, and can slide in the sliding groove 715 along the length direction of the base rod 72 and rotate itself. A linear driving member 74 connected to the driving rod 73 is provided on the workbench 4. The linear driving member 74 in this embodiment is a cylinder, and in other embodiments it can also be a hydraulic cylinder, an electric push rod, etc. A feed port 75 for heavy dust to pass through can be formed between the first plate 711 and the second plate 712 in the two adjacent groups. The linear driving member 74 can drive the driving rod 73 to slide up so that the feeding port 75 can be opened, and the linear driving member 74 can drive the driving rod 73 to move downward so that the feeding port 75 can be closed.

[0058] When heavy dust needs to be cleaned, the linear drive member 74 drives the drive rod 73 to move downward, and while the first plate 711 and the second plate 712 rotate, the feed port 75 is blocked, so that the closing plate 71 can block the top of the conveyor belt mechanism 61, thereby effectively preventing the dust generated during the movement of the conveyor belt mechanism 61 from spreading into the processing area again, thereby improving the efficiency of dust cleaning; after cleaning, the linear drive member 74 drives the drive rod 73 to move upward, and the feed port 75 is opened, so that the heavy dust can fall onto the conveyor belt mechanism 61.

[0059] The implementation principle of the dust suction device for the spindle head of a composite material machining center in an embodiment of the present application is as follows: when processing the composite material in the processing area, the dust collector 53 suctions and collects the light dust generated in the processing area through the main dust suction duct 51 and the branch dust suction duct 52, and the heavy dust falls onto the conveyor belt mechanism 61 under the action of gravity, and is then transported to the material holding box 63 through the conveyor belt mechanism 61 for collection. In this way, the dust generated during the processing of the composite material can be suctioned, effectively avoiding the harm caused by dust to the staff.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
