During the milling process, the generated dust and particulate matter are sucked into the dust collection pipe 3 through the milling drill bit, so that the dust can be effectively cleaned.

[0032] Furthermore, a dust hood 5 is provided at the bottom of the dust suction pipe 3, and a silicone sleeve 6 is provided at the bottom of the dust suction pipe 3. When in use, the bottom of the dust suction pipe 3 is connected to the dust suction hood 5, and the dust suction hood 5 is connected with the bottom of the dust suction pipe 3 to form a complete dust suction channel. The silicone sleeve 6 is installed on the side wall of the dust suction hood 5. The silicone sleeve 6 has good elasticity and sealing. When the dust suction hood 5 is close to the surface of the workpiece, a gap is prevented from forming between the dust suction hood 5 and the milling drill bit, thereby reducing air leakage and improving dust suction efficiency.

[0033] Furthermore, a following fitting mechanism 7 is provided inside the dust hood 5, and the dust hood 5 and the dust head always follow the movement of the milling drill bit and fit on the surface of the curved workpiece through the following fitting mechanism 7. When in use, the following fitting mechanism 7 is provided inside the dust hood 5, and the following fitting mechanism 7 inside the dust hood 5 enables the dust collector to be adaptively adjusted according to the movement of the milling drill bit, so that the dust collector can automatically adjust as the curvature of the workpiece surface changes, always maintain the best dust collection state, avoid displacement or separation of the dust hood 5 due to vibration or other external forces, ensure that the dust hood 5 always keeps a close fit with the milling area, improve the dust collection efficiency and effectively prevent dust leakage.

[0034] Furthermore, a floating connection mechanism 8 is provided between the floating plate 2 and the milling drill bit, and the floating connection mechanism 8 enables the floating plate 2 to move within a certain range. When in use, the floating connection mechanism 8 enables the dust collecting device to flexibly adapt to the up and down floating of the milling drill bit, maintain a stable dust collecting position, and float relative to the milling drill bit within a certain range to adapt to the slight vibration and position change during the milling process, ensuring the stable contact between the dust collecting hood 5 and the workpiece surface, and avoiding the situation of incomplete dust collection or inconvenient operation caused by the fixed position installation of the dust collecting hood 5.

[0035] Through the design of this embodiment, the dust collection tube 3 can be made to fit tightly between the dust collection hood 5 and the surface of the workpiece during explosion-proof dust collection, and the sealing effect of the silicone sleeve 6 can greatly improve the dust collection efficiency and reduce dust leakage.

[0036] 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 and poor vacuuming effect during the vacuuming process.

[0037] Embodiment 2

[0038] refer to Figure 3 , Figure 4 and Fig. 9 As shown, according to the curvature adjustment explosion-proof dust suction device recorded in the above-mentioned 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 arranged at the bottom of the through-tube, the mounting seat 71 is a cube, a hinge shaft 72 arranged on the side wall of the mounting seat 71, four connecting plates 73 arranged 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 is arranged between the outer ends of two adjacent oblique triangular blocks 74, the support spring 75 is hollowed out, and a lower following head 76 is arranged at one end of the oblique triangular block 74, and a ball 77 is embedded at the bottom of the lower following head 76. In this embodiment, by describing in detail the materials, structures and logical connections of each part, and associating other possible implementation methods, the device has higher practicality and easier operation.

[0039] Specifically, a cubic mounting seat 71 is arranged at the bottom of the through-tube, a hinge shaft 72 is arranged 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 plate 73 is hinged and rotated around the hinge shaft 72, oblique triangular blocks 74 are arranged on both sides of the connecting plate 73, and a support spring 75 is arranged between the outer ends of two adjacent oblique triangular blocks 74, and the support spring 75 is hollow. It should be understood that the mounting base 71, the hinge shaft 72, the connecting plate 73 and the oblique triangular block 74 can be made of high-strength stainless steel material to ensure its wear resistance and corrosion resistance, while ensuring that it does not deform under long-term working conditions. During use, the connecting plate 73 can rotate around the hinge shaft 72 within a certain range, and 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 up and down, 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 spring 75 provides effective supporting force for the two oblique triangular blocks 74. When vacuuming a curved workpiece, the oblique triangular block 74 at the bottom contacts and is squeezed by the surface of the curved workpiece. At this time, the connecting plate 73 rotates and the oblique triangular block 74 at the top moves downward. In this process, the overlapping oblique triangular blocks 74 squeeze the support spring 75. In this process, through the linkage effect of multiple oblique triangular blocks 74, the oblique triangular blocks 74 and the connecting plate 73 can automatically adjust their shapes when fitting to surfaces of different curvatures, maintain close contact with the surface of the workpiece, so that the vacuum head and the vacuum hood 5 can adapt to the outer arc surface of the workpiece, so that the vacuum hood 5 can always fit closely to the surface of the workpiece.

[0040] Furthermore, a lower following head 76 is provided at the bottom of the oblique triangle block 74 at the bottom, and a ball bearing 77 is embedded at the bottom of the lower following head 76. During use, the lower following head 76 and the ball bearing 77 can greatly reduce the friction between the following fitting mechanism 7 and the workpiece surface, so that the dust collector moves more smoothly when following the milling drill bit, and also improves the dust collection efficiency.

[0045] Specifically, floating bearings 81 are provided at the four corners of the fixed plate 1. Four floating bearings 81 are provided at the four corners of the fixed plate 1. These floating bearings 81 allow for micro-movement and rotation in multiple directions within a certain range. The bottom of the floating bearing 81 is connected to the floating plate 2, and the floating plate 2 carries the dust collecting device. The milling drill cuts on the surface of the workpiece, generating dust. Since there may be micro-curvature changes or unevenness on the surface of the workpiece, as well as vibrations generated during the milling process, the dust collecting device needs to be able to automatically adjust its position and angle to keep the dust collecting hood 5 in close contact with the surface of the workpiece. At this time, the floating connection mechanism 8 begins to work, and the floating bearings 81 allow the floating plate 2 and the dust collecting device thereon to move and rotate slightly within a certain range to adapt to changes in the surface of the workpiece and vibrations during the milling process. This automatic adjustment mechanism ensures that the dust collecting device can always be in close contact with the surface of the workpiece, thereby effectively collecting dust.

[0046] Furthermore, a mounting head 82 is installed on the top of the floating bearing 81, and the mounting head 82 penetrates the fixed plate 1. When in use, a mounting head 82 is provided on the top of each floating bearing 81, and these mounting heads 82 penetrate the fixed plate 1 and fit tightly with the inside of the floating bearing 81, ensuring that the floating bearing 81 can be stably mounted on the fixed plate 1. The design of the mounting head 82 not only provides the necessary support and guiding function, but also allows the floating bearing 81 to move and rotate slightly in the mounting head 82, thereby realizing the position and angle adjustment of the dust collecting device.

[0047] 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 the changes in the workpiece surface and the vibration during the milling process.

[0056] Specifically, the reinforcing strip 91 used to strengthen the floating plate 2 and the dust suction pipe 3, the movable mounting groove 92 and the mounting hole 93 at the top of the reinforcing strip 91 are connected by mounting bolts. When in use, the reinforcing strip 91 is fixedly connected to the two side walls of the dust suction pipe 3. Its design not only increases the rigidity of the dust suction pipe 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 an operating space for the mounting bolts. A movable mounting groove 92 is opened at the top of the reinforcing strip 91.

During use, the dust suction pipe 3 can be slightly deformed to a certain extent by the arrangement of the first deformation groove 11 and the second deformation groove 12, so that the milling spindle and the floating plate 2 can move to a certain extent, thereby preventing the vibration of the milling spindle from causing displacement of the floating plate 2.

[0067] Through the design of this embodiment, a certain range of movement can be achieved between the dust suction pipe 3 and the floating plate 2, so that the dust suction pipe 3 can always move with the workpiece being processed.

[0068] 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 a rigid collision between the dust suction pipe 3 and the workpiece due to the fixed installation of the dust suction pipe 3.

[0069] Embodiment 8

[0070] refer to Figure 6 As shown, according to the curvature adjustment explosion-proof dust suction device described in the above-mentioned embodiment, four gaskets 13 are arranged 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 arranged 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.

[0071] 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. When in use, the support ring 14 supports the mounting head 82, and the staggered opening design of the support ring 14 also increases the elasticity of the support ring 14, so that it can better absorb and disperse the impact force during the installation process, protecting the mounting head 82 from damage.

[0072] Through the design of this embodiment, a certain range of movement can be allowed between the mounting head 82 and the fixed plate 1, and a movable connection between the floating plate 2 and the fixed plate 1 is further achieved, thereby improving the mobility between the dust collection tube 3 and the dust collection head.

[0073] 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 suction pipe 3 and the dust suction head can flexibly adapt to the dust suction operation of the outer arc-shaped workpiece.

[0074] Embodiment 9

[0075] refer to Figure 5 As shown, according to the curvature-adjustable explosion-proof dust suction device described in the foregoing 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 the floating plate 2 and the fixed plate 1 from generating static electricity.

[0076] Specifically, grounding interfaces 15 are provided on both side walls of the fixed plate 1 and the floating plate 2, and the grounding interfaces 15 are used to connect the grounding wire. When in use, the grounding wire is connected to the grounding interface 15, and the function of the grounding interface 15 is to release static electricity to the ground through an electrical conductor to prevent static electricity accumulation due to friction or external environmental factors during the use of the fixed plate 1 and the floating plate 2. Static electricity accumulation may cause electronic equipment to malfunction, be damaged or have performance degradation, and the static electricity is quickly introduced into the ground through the grounding interface 15, effectively reducing the risk of equipment failure.

[0077] Through the design of this embodiment, the accumulated static electricity can be effectively released to the ground, thereby avoiding damage to the fixed plate 1, the floating plate 2 and other electronic components caused by static electricity, and ensuring the long-term stable operation of the equipment.

[0078] 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.

[0079] Embodiment 10

[0080] 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.

[0081] 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 to ensure that it can meet the field of view requirements of the thermal imaging camera while not affecting the overall sealing and protective performance of the silicone sleeve. Through such a design, the thermal imaging camera can conveniently observe the internal situation from the outside through the viewing window 16 without being directly installed in the silicone sleeve, thereby simplifying the structure of the entire system and improving the flexibility of use.

[0082] The advantage of this embodiment is that the viewing window 16 not only provides good visibility, allowing the operator to monitor the milling process in real time through the thermal imaging camera, but also maintains the original sealing and protection capabilities of the silicone sleeve. In addition, this method also avoids the increased installation complexity and equipment damage risks caused by directly installing the camera inside the silicone sleeve, further improving the reliability and service life of the overall system.

[0083] 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 protection scope of the present invention.
