Description

Technical Field

[0001] The present invention relates to the field of dust collecting devices, in particular to a curvature-adjustable explosion-proof dust collecting device. Background Art

[0002] In the metal processing, wood processing and other material processing industries, milling lathes are commonly used processing equipment for performing precise milling operations on workpieces. A large amount of dust and debris will be generated during the milling process. This dust will not only pollute the working environment and affect the health of operators, but may also cause damage to equipment and reduce processing accuracy and efficiency. Therefore, during the operation of milling lathes, effective dust collection and treatment is crucial.

[0003] A large amount of dust and particulate matter will be generated during the production process, which may also cause explosion accidents and pose a huge safety hazard. With the continuous development of industrial technology, the requirements for dust collection devices are becoming higher and higher, especially in some high-end manufacturing fields such as aerospace and precision instrument manufacturing. The requirements for processing accuracy and working environment are extremely strict. Traditional dust collection devices can no longer meet these needs.

[0004] However, existing dust collection devices still have some problems that need to be solved when performing dust collection operations during workpiece processing, such as:

[0063] The present invention provides the following preferred embodiments:

[0064] Example 1

[0065] refer to Figure 1 and Figure 2As shown, this embodiment provides a curvature-adjusted explosion-proof dust suction device, which includes: a fixed plate 1 fixedly mounted on the milling spindle, a floating plate 2 arranged on the milling spindle, a dust suction pipe 3 arranged at one end of the floating plate 2, the dust suction pipe 3 is curved, and the bottom of the dust suction pipe 3 is located below the milling spindle, a through-tube 4 arranged on the inner wall of the dust suction pipe 3, the milling drill bit is located inside the through-tube 4, a dust suction hood 5 arranged at the bottom of the dust suction pipe 3, the dust suction hood 5 is connected to the bottom of the dust suction pipe 3, a silicone sleeve 6 is arranged on the side wall of the dust suction hood 5, a following and fitting mechanism 7 is arranged inside the dust suction hood 5, and a floating connection mechanism 8 is arranged between the fixed plate 1 and the floating plate 2.

[0066] Specifically, a fixed plate 1 is fixedly connected to the milling spindle, providing a mounting base for the dust collection device. The fixed plate 1 is connected to a floating plate 2 via a floating connection mechanism 8. A floating plate 2 is mounted on the milling spindle, with a dust collection tube 3 mounted at one end. The milling drill bit is located within a through-tube 4. During use, the dust collection tube 3 has a curved structure, with its bottom located below the milling spindle. The dust collection tube 3 is connected to an external dust collection device, directly collecting dust and waste generated by the milling drill head. During the milling process, dust and particulate matter generated are sucked into the dust collection tube 3 through the milling drill bit, achieving effective dust collection and cleaning.

[0067] Furthermore, a dust hood 5 is provided at the bottom of the dust collection tube 3, and a silicone sleeve 6 is provided at the bottom of the dust collection hood 5. When in use, the bottom of the dust collection tube 3 is connected to the dust collection hood 5, and the dust collection hood 5 and the bottom of the dust collection tube 3 are connected to form a complete dust collection channel. The silicone sleeve 6 is installed on the side wall of the dust collection hood 5. The silicone sleeve 6 has good elasticity and sealing properties. When the dust collection hood 5 is in close contact with the surface of the workpiece, it prevents the dust collection hood 5 from forming a gap with the milling drill bit, thereby reducing air leakage and improving dust collection efficiency.

[0068] Furthermore, a follow-up fitting mechanism 7 is provided inside the dust hood 5. This follows the dust hood 5 and the dust collection head so that they always follow the movement of the milling drill bit and adhere to the surface of the curved workpiece. During use, the follow-up fitting mechanism 7 is provided inside the dust hood 5. The follow-up fitting mechanism 7 inside the dust hood 5 allows the dust collection device to adaptively adjust according to the movement of the milling drill bit, so that the dust collection device can automatically adjust as the curvature of the workpiece surface changes, always maintaining an optimal dust collection state, avoiding displacement or separation of the dust hood 5 due to vibration or other external forces, ensuring that the dust hood 5 always maintains a tight fit with the milling area, improving dust collection efficiency and effectively preventing dust leakage.

[0069] Furthermore, a floating connection mechanism 8 is provided between the floating plate 2 and the milling drill bit, which enables the floating plate 2 to move within a certain range. During use, the floating connection mechanism 8 enables the dust collection device to flexibly adapt to the up and down movement of the milling drill bit, maintaining a stable dust collection position. It floats within a certain range relative to the milling drill bit to accommodate minor vibrations and position changes during the milling process, ensuring that the dust collection hood 5 maintains a stable contact with the workpiece surface, and avoiding incomplete dust collection or inconvenient operation caused by the dust collection hood 5 being installed in a fixed position.

[0070] Through the design of this embodiment, the dust collection tube 3 can be made to fit tightly with the surface of the workpiece during explosion-proof dust collection, and the silicone sleeve 6 has a sealing effect, which greatly improves the dust collection efficiency and reduces dust leakage. The dust collection device can adapt to the surfaces of workpieces with different curvatures, broadens the scope of application, effectively absorbs vibrations during milling, improves the stability of the dust collection device and extends its service life. The efficient dust collection capacity reduces the dust concentration in the working area and reduces safety hazards such as explosions.

[0071] The benefit of this embodiment is that, through the cooperation of the following fitting mechanism 7 and the floating connection mechanism 8, it can effectively solve the problems existing in traditional equipment that the vacuum head cannot fit the surface of the workpiece and the vacuum head cannot move with the milling drill bit, thereby avoiding the escape of dust during the vacuuming process and the problem of poor vacuuming effect.

[0072] Example 2

[0073] refer to Figure 3 、 Figure 4 and Figure 9 As shown, according to the curvature adjustment explosion-proof dust suction device described in the above embodiment, this embodiment describes in detail the composition of the following and fitting mechanism 7. Specifically, the following and fitting mechanism 7 includes: a mounting seat 71 provided at the bottom of the through-tube, the mounting seat 71 is a cube, a hinge shaft 72 provided on the side wall of the mounting seat 71, four connecting plates 73 provided on the side wall of the mounting seat 71, the connecting plates 73 are hingedly matched with the hinge shaft 72, oblique triangular blocks 74 are fixedly connected to the two side walls of the connecting plate 73, the positions of two adjacent oblique triangular blocks 74 are overlapped, the oblique triangular blocks 74 located on both sides of the connecting plate 73 are staggered up and down, a support spring 75 provided between the outer ends of two adjacent oblique triangular blocks 74, the support spring 75 is hollowed out, and a lower following head 76 provided at one end of the oblique triangular block 74, the bottom of the lower following head 76 is inlaid with a ball 77. In this embodiment, by describing in detail the materials, structures and logical connections of each part, and by associating other possible implementation methods, the device has higher practicality and easier operation.

[0074] Specifically, a cube-shaped mounting seat 71 is provided at the bottom of the through-tube, a hinge shaft 72 is provided on the side wall of the mounting seat 71, four connecting plates 73 are installed on the side wall of the mounting seat 71, the connecting plates 73 are hinged and rotated around the hinge shaft 72, oblique triangular blocks 74 are provided on both sides of the connecting plates 73, and a support spring 75 is provided between the outer ends of two adjacent oblique triangular blocks 74, and the support spring 75 is hollowed out. It should be understood that the materials for the mounting base 71, the hinge shaft 72, the connecting plate 73 and the oblique triangular block 74 can be selected from high-strength stainless steel to ensure their wear resistance and corrosion resistance, while ensuring that they will not deform under long-term working conditions. During use, the connecting plate 73 can rotate within a certain range around the hinge shaft 72. The design of the oblique triangular block 74 enables two adjacent oblique triangular blocks 74 to form a continuous, curved surface-adaptive structure when their positions coincide. In particular, the oblique triangular blocks 74 on both sides of the connecting plate 73 are staggered in an up-and-down manner, and a support spring 75 is provided between the outer ends of the two adjacent oblique triangular blocks 74. The support spring 75 is a hollow design. The support springs 75 provide effective supporting force for the two oblique triangular blocks 74. When vacuuming a curved workpiece, the oblique triangular block 74 at the bottom contacts the surface of the curved workpiece and is squeezed. At this time, the connecting plate 73 rotates and the oblique triangular block 74 at the top moves downward. In this process, the oblique triangular blocks 74 that overlap in position squeeze the support springs 75. This process is achieved through the linkage of multiple oblique triangular blocks 74, so that the oblique triangular blocks 74 and the connecting plate 73 can automatically adjust their shapes when fitting surfaces with different curvatures, maintain close contact with the surface of the workpiece, and enable the vacuum head and the vacuum hood 5 to adapt to the outer curved surface of the workpiece, so that the vacuum hood 5 can always fit closely with the surface of the workpiece.

[0075] Furthermore, a lower follower head 76 is provided at the bottom of the oblique triangular block 74, and a ball bearing 77 is embedded in the bottom of the lower follower head 76. During use, the lower follower head 76 and the ball bearing 77 can greatly reduce the friction between the follower and fitting mechanism 7 and the workpiece surface, making the dust collector smoother when following the movement of the milling drill bit, while also improving dust collection efficiency.

[0076] Through the design of this embodiment, the dust suction tube 3 and the dust suction head can always fit the surface of the workpiece, and can adapt to the deformation of workpieces with different outer arcs, so that the dust suction hood 5 can closely fit the surfaces of workpieces with various curvatures, greatly improving the dust suction efficiency and reducing dust leakage, making the follow-up fitting mechanism 7 more flexible and adaptable when fitting surfaces with different curvatures, greatly reducing the friction between the workpiece surface, improving the smoothness of the movement of the dust suction hood 5, and also extending the service life of the dust suction device.

[0077] The benefit of this embodiment is that the following fitting mechanism 7 in the present invention, through its unique working principle and design, realizes effective control of the close fitting between the dust hood 5 and the workpiece surface, and provides an efficient and flexible dust collection solution for the curvature-adjusted explosion-proof dust collection device.

[0078] Example 3

[0079] refer to Figure 5 and Figure 7 As shown, based on the curvature-adjustable explosion-proof dust collection device described in the previous embodiment, this embodiment details the structure of the floating connection mechanism 8. Specifically, the floating connection mechanism 8 includes four floating bearings 81 disposed at the four corners of the fixed plate 1. The bottoms of the floating bearings 81 are connected to the floating plate 2, and mounting heads 82 are disposed on the tops of the floating bearings 81 and extend through the fixed plate 1.

[0080] Specifically, floating bearings 81 are installed at the four corners of the fixed plate 1. These four floating bearings 81 allow for microscopic movement and rotation in multiple directions within a certain range. The bottoms of the floating bearings 81 are connected to the floating plate 2, which in turn supports the dust collection device. As the milling drill cuts the workpiece surface, dust is generated. Due to slight variations in curvature or unevenness on the workpiece surface, as well as vibrations generated during milling, the dust collection device must automatically adjust its position and angle to maintain a tight fit between the dust collection hood 5 and the workpiece surface. At this point, the floating connection mechanism 8 comes into play. The floating bearings 81 allow for microscopic movement and rotation of the floating plate 2 and the dust collection device mounted thereon within a certain range to accommodate variations in the workpiece surface and vibrations during milling. This automatic adjustment mechanism ensures that the dust collection device maintains a tight fit between the workpiece surface and effectively collects dust.

[0081] Furthermore, a mounting head 82 is mounted on the top of the floating bearing 81, which extends through the fixed plate 1. During use, each floating bearing 81 is provided with a mounting head 82, which extends through the fixed plate 1 and fits tightly within the floating bearing 81, ensuring that the floating bearing 81 is stably mounted on the fixed plate 1. The design of the mounting head 82 not only provides the necessary support and guidance, but also allows the floating bearing 81 to move and rotate slightly within the mounting head 82, thereby achieving position and angle adjustment of the dust collection device.

[0082] Through the design of this embodiment, the dust collection device can flexibly adapt to the up and down floating of the milling drill bit and maintain a stable dust collection position. The floating connection mechanism 8 allows the floating plate 2 and the dust collection device thereon to move and rotate slightly within a certain range through the floating bearing 81 to adapt to changes in the workpiece surface and vibrations during the milling process. This automatic adjustment mechanism ensures that the dust collection device can always fit closely to the workpiece surface, thereby effectively collecting dust.

[0083] The benefit of this embodiment is that it avoids incomplete dust collection or inconvenient operation caused by the fixed position installation of the dust hood 5. The floating connection mechanism 8 can effectively absorb external loads and vibrations through the flexibility of the floating bearing 81, making the equipment more stable during operation, avoiding movement impact or instability caused by fixed connection, and significantly improving the stability of the equipment.

[0084] Example 4

[0085] refer to Figure 2 As shown, according to the curvature-adjustable explosion-proof dust suction device described in the aforementioned embodiment, a connecting assembly 9 is provided between the floating plate 2 and the dust suction pipe 3 , and the connecting assembly 9 is used to enhance the connection strength between the floating plate 2 and the dust suction pipe 3 .

[0086] Specifically, a connecting assembly 9 is provided between the floating plate 2 and the dust suction pipe 3. When in use, the connecting assembly 9 strengthens the connection strength between the floating plate 2 and the dust suction pipe 3, so that the dust suction pipe 3 and the dust suction cover 5 will not be affected by external vibration, friction, etc., which may cause the dust suction pipe 3 to fall off.

[0087] Through the design of this embodiment, the connection between the floating plate 2 and the dust suction pipe 3 can be made more secure, thereby avoiding problems such as loosening or falling off caused by vibration or external force generated when the dust suction pipe 3 is working.

[0088] The benefit of this embodiment is that the provision of the connection assembly 9 can enhance the stability and firmness of the connection, reduce the need for frequent maintenance or replacement of components, and thus extend the service life of the equipment.

[0089] Example 5

[0090] refer to Figure 3 and Figure 5 As shown, according to the curvature-adjustable explosion-proof dust suction device described in the aforementioned embodiment, the connecting assembly 9 includes: a reinforcement strip 91 fixedly connected to the two side walls of the dust suction pipe 3, the top of the reinforcement strip 91 is located on one side of the floating plate 2, a movable mounting groove 92 is opened at the top of the reinforcement strip 91, and mounting holes 93 are arranged on both sides of the floating plate 2, and the movable mounting groove 92 and the mounting holes 93 are connected by bolts.

[0091] Specifically, the reinforcing strip 91 used to reinforce the floating plate 2 and the dust suction tube 3 has a movable mounting groove 92 and mounting holes 93 at its top connected by mounting bolts. When in use, the reinforcing strip 91 is fixedly connected to the two side walls of the dust suction tube 3. This design not only increases the rigidity of the dust suction tube 3 but also provides an additional support surface for the floating plate 2. The top of the reinforcing strip 91 is located on one side of the floating plate 2, forming a certain spatial relationship with the floating plate 2, providing operating space for the mounting bolts. A movable mounting groove 92 is defined at the top of the reinforcing strip 91. This mounting groove has a certain width and depth, allowing the mounting bolts to be adjusted within a certain range during installation to accommodate slight positional deviations between the floating plate 2 and the dust suction tube 3. Mounting holes 93 corresponding to the movable mounting grooves 92 are defined on both sides of the floating plate 2. These mounting holes 93 provide passageways for the mounting bolts to pass through and, together with the movable mounting grooves 92, form a complete bolted structure.

[0092] Through the design of this embodiment, a reinforced connection between the floating plate 2 and the dust suction tube 3 can be achieved. The mounting bolt passes through the mounting hole 93 of the floating plate 2 and enters the movable mounting groove 92 of the reinforcement bar 91. Since the movable mounting groove 92 has a certain tolerance, the mounting bolt can be fine-tuned in the groove to ensure a tight fit between the floating plate 2 and the dust suction tube 3.

[0093] The benefit of this embodiment is that, through the cooperation of the reinforcement strip 91 , the movable mounting groove 92 and the mounting hole 93 , a stable reinforced connection between the dust suction pipe 3 and the floating plate 2 is achieved, thereby improving the stability and durability of the dust suction device.

[0094] Example 6

[0096] Specifically, an upper follower head 10 is provided on the top of the oblique triangle block 74. The tops of the upper follower head 10 and the lower follower head 76 extend into the interior of the support spring 75. When in use, the upper follower head 10 and the lower follower head 76 extend into the interior of the support spring 75, limiting the position of the support spring 75 and ensuring stable movement of the support spring 75.

[0097] Through the design of this embodiment, the support spring 75 can be limited so that the support spring 75 can move stably.

[0098] The benefit of this embodiment is that it prevents the support spring 75 from being disengaged due to the deformation of the oblique triangular block 74 .

[0099] Example 7

[0101] Specifically, the first and second deformation grooves 11, 12 are located on either side of the floating plate 2. The dust suction tube 3 is located in the middle of the first deformation groove 11, and the milling spindle is located in the middle of the second deformation groove 12. During use, the first and second deformation grooves 11, 12 allow the dust suction tube 3 to undergo a certain degree of micro-deformation, allowing for a certain degree of movement between the milling spindle and the floating plate 2, thereby preventing displacement of the floating plate 2 caused by vibration of the milling spindle.

[0102] Through the design of this embodiment, it is possible to achieve a certain range of movement between the dust suction pipe 3 and the floating plate 2, so that the dust suction pipe 3 can always move along with the workpiece being processed.

[0103] The benefit of this embodiment is that the dust suction pipe 3 can move within a certain range in the middle of the floating plate 2, thereby avoiding rigid collision between the dust suction pipe 3 and the workpiece due to the fixed installation of the dust suction pipe 3.

[0104] Example 8

[0105] refer to Figure 6 As shown, according to the curvature adjustment explosion-proof dust suction device described in the aforementioned embodiment, four gaskets 13 are provided on the top of the fixed plate 1, the gasket 13 is located in the middle of the mounting head 82, and a support ring 14 is provided between the gasket 13 and the mounting head 82. The support ring 14 is open and the beginning of the support ring 14 is staggered.

[0106] Specifically, a gasket 13 is installed in the middle of the mounting head 82, and a support ring 14 is placed between the gasket 13 and the mounting head 82. During use, the support ring 14 supports the mounting head 82. The staggered opening design of the support ring 14 also increases the elasticity of the support ring 14, allowing it to better absorb and disperse impact forces during installation, protecting the mounting head 82 from damage.

[0107] Through the design of this embodiment, a certain range of movement can be allowed between the mounting head 82 and the fixed plate 1, further realizing a movable connection between the floating plate 2 and the fixed plate 1, and improving the mobility between the dust collection tube 3 and the dust collection head.

[0108] The benefit of this embodiment is that the movable space between the mounting plate and the floating plate 2 is expanded, so that the dust collection pipe 3 and the dust collection head can flexibly adapt to the dust collection operation of the outer arc-shaped workpiece.

[0109] Example 9

[0110] refer to Figure 5 As shown, according to the curvature-adjustable explosion-proof dust collection device described in the aforementioned embodiment, grounding interfaces 15 are provided on both side walls of the fixed plate 1 and the floating plate 2 , and the grounding connectors are used to prevent static electricity from being generated on the floating plate 2 and the fixed plate 1 .

[0111] Specifically, grounding interfaces 15 are provided on both side walls of the fixed plate 1 and the floating plate 2. Grounding interfaces 15 are used to connect to ground wires. During use, the ground wires are connected to grounding interfaces 15. Grounding interfaces 15 discharge static electricity to the ground via electrical conductors. This prevents static electricity from accumulating on the fixed plate 1 and the floating plate 2 due to friction or external environmental factors during use. Static electricity accumulation can cause electronic equipment to malfunction, damage, or performance degradation. By quickly conducting static electricity to the ground through grounding interfaces 15, the risk of equipment failure is effectively reduced.

[0112] Through the design of this embodiment, the accumulated static electricity can be effectively released to the ground, thereby preventing the static electricity from damaging the fixed plate 1, the floating plate 2 and other electronic components, and ensuring the long-term stable operation of the equipment.

[0113] The benefit of this embodiment is that it puts operators and equipment in a safer working environment, avoids equipment failure due to static electricity accumulation, and thus improves work efficiency and productivity.

[0114] Example 10

[0115] refer to Figure 8 As shown, according to the curvature adjustment explosion-proof dust suction device described in the above embodiment, a viewing window 16 is provided on the side wall of the silicone sleeve 6. The main function of the viewing window 16 is to provide a clear field of view for the thermal imaging camera to facilitate imaging monitoring during the milling process.

[0116] Specifically, a viewing window 16 is provided on one side of the silicone sleeve 6. The design of this embodiment fully considers the size, shape, and position of the viewing window, ensuring it meets the thermal imaging camera's field of view while maintaining the overall sealing and protective performance of the silicone sleeve. This design allows the thermal imaging camera to conveniently observe the internal conditions from the outside through the viewing window 16, without having to be directly installed in the silicone sleeve. This simplifies the overall system construction and increases operational flexibility.

[0117] The advantage of this embodiment is that the viewing window 16 not only provides excellent visibility, allowing the operator to monitor the milling process in real time through the thermal imaging camera, but also maintains the original sealing and protective capabilities of the silicone sleeve. In addition, this approach avoids the increased installation complexity and risk of equipment damage that may arise from installing the camera directly inside the silicone sleeve, further improving the reliability and service life of the entire system.

[0118] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
