Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0028] like Figures 1-5 As shown, a grinding device for producing rotary flanges according to one embodiment of the present invention includes a main body mechanism 1, a clamping mechanism 2, a grinding mechanism 3, and a dust collection mechanism 4. The main body mechanism 1 includes an operating table 11; the clamping mechanism 2 includes a pair of arc-shaped clamping plates 21 and a driving component. The pair of arc-shaped clamping plates 21 are arranged opposite to each other on the operating table 11, and the driving component is used to drive the movement of the pair of arc-shaped clamping plates 21; the grinding mechanism 3 includes a grinding disc 31, a heat dissipation component, and an adjustment component. The grinding disc 31 is arranged above the pair of arc-shaped clamping plates 21. The heat dissipation component is used to dissipate heat from the grinding disc 31, and the adjustment component is used to adjust the distance between the grinding disc 31 and the pair of arc-shaped clamping plates 21; the dust collection mechanism 4 includes a dust collection hood 41 arranged on one side of the pair of arc-shaped clamping plates 21, and a negative pressure dust collection component for providing negative pressure to the dust collection hood 41.

[0029] When using this rotary flange production grinding device, a pair of arc-shaped clamping plates 21 are moved by the drive component to clamp and fix the flange of the rotary flange, ensuring that the flange does not rotate during grinding. The height of the grinding disc 31 is adjusted by the adjustment component so that the grinding disc 31 contacts the fixed flange surface, and the rotation of the grinding disc 31 enables rapid grinding of the flange. The grinding disc 31 generates heat when grinding the flange, which is quickly absorbed by the heat dissipation component and released to the outside, ensuring high heat dissipation efficiency during flange grinding, thereby improving the grinding efficiency and grinding effect of the flange. In addition, when the grinding disc 31 grinds the flange, the negative pressure dust collection component is activated simultaneously, so that the dust collection hood 41 is in a negative pressure state, so that the metal dust generated by the grinding disc 31 during flange grinding is absorbed and treated by the dust collection hood 41, avoiding dust contact with operators and ensuring the health of operators.

[0030] like Figure 4 As shown, the arc-shaped clamp 21 is L-shaped. The L-shaped arc-shaped clamp 21 provides a better clamping and fixing effect on the flange of the rotating flange, ensuring the stability of the flange fixing. Protective layers 22 are provided on both the inner and outer walls of the arc-shaped clamp 21. The protective layers 22 are used to contact the flange, ensuring that the arc-shaped clamp 21 will not damage the surface of the flange when clamping and fixing it. At the same time, the arc-shaped clamp 21 can achieve visual fixing of both the inner and outer rings of the flange through its inner and outer walls, facilitating the grinding of the inner and outer walls of the flange.

[0031] like Figures 2-4 As shown, the drive assembly includes a slide rail 23, a pair of sliders 24, a pair of support plates 25, and a bidirectional screw 26. The slide rail 23 is located on the operating table 11, and the pair of sliders 24 are slidably connected within the slide rail 23.

[0032] like Figures 2-4 As shown, the bidirectional screw 26 is rotatably mounted within the slide rail 23 along its length. A pair of sliders 24 are threaded onto the positive and negative threads of the bidirectional screw 26, respectively. One end of the bidirectional screw 26 extends to the outside of the operating table 11 and is fixed with a handle. By rotating the bidirectional screw 26 within the slide rail 23 using the handle, the pair of sliders 24 can be driven to move closer to or further away from each other within the slide rail 23.

[0033] like Figures 2-4As shown, a pair of sliders 24 are fixedly connected to a pair of support plates 25 at their upper ends, and a pair of arc-shaped clamping plates 21 are fixedly connected to the bottom of the pair of support plates 25 respectively. The rotation of the bidirectional screw 26 drives the pair of sliders 24 to move closer to or further away from each other within the slide rail 23, which in turn drives the pair of support plates 25 to move, thereby driving the pair of arc-shaped clamping plates 21 to move closer to or further away from each other. Thus, the rotating flange can be clamped and fixed by the pair of arc-shaped clamping plates 21.

[0034] like Figure 3 and Figure 5 As shown, the heat dissipation assembly includes a chamber 32, a phase change material 33, multiple heat dissipation fins 34, and multiple heat-conducting rods 35. The chamber 32 is located within the grinding disc 31, and the phase change material 33 is filled within the chamber 32. The phase change material 33 is an endothermic phase change material, preferably a paraffin-based phase change material.

[0035] like Figure 3 and Figure 5 As shown, multiple heat dissipation fins 34 are fixedly mounted on the outer wall of the grinding disc 31 at equal intervals. Multiple heat-conducting rods 35 extend from the outside of the grinding disc 31 into the chamber 32. One end of each heat-conducting rod 35 is fixedly connected to one of the heat dissipation fins 34. The heat generated by the grinding disc 31 during flange grinding is rapidly absorbed by the phase change material 33. The phase change material 33 then transfers the absorbed heat to the heat dissipation fins 34 through the heat-conducting rods 35. When the grinding disc 31 rotates the heat dissipation fins 34, the heat dissipated by the heat dissipation fins 34 is absorbed by the air, thereby achieving rapid cooling of the grinding disc 31.

[0036] like Figure 3 and Figure 5As shown, the adjustment assembly includes a motor 36, a mounting plate 37, a fixing plate 38, an adjusting screw 39, a pair of guide rods 310, and a support frame 311. The drive end of the motor 36 is mounted on the grinding disc 31. The mounting plate 37 is fixed to the motor 36. The support frame 311 is fixed to the operating table 11. The fixing plate 38 is fixed to the end of the support frame 311 away from the operating table 11. The adjusting screw 39 is threaded to the fixing plate 38 in a through manner. The lower end of the adjusting screw 39 is rotatably connected to the mounting plate 37. The pair of guide rods 310 are fixed to the bottom of the fixing plate 38, and the lower ends of the pair of guide rods 310 are slidably connected to the mounting plate 37 in a through manner. To accommodate the grinding of different flanges held and fixed by a pair of arc-shaped clamping plates 21, and to facilitate the clamping and removal of flanges within the arc-shaped clamping plates 21, the height of the grinding disc 31 is adjusted by an adjusting assembly. During adjustment, the adjusting screw 39 is rotated, which in turn drives the mounting plate 37 to move up and down. This movement of the mounting plate 37 in turn drives the grinding disc 31 to move up and down. Simultaneously, under the action of a pair of guide rods 310, the grinding disc 31 moves up and down in a linear motion.

[0037] like Figures 1-3 As shown, the negative pressure dust collection assembly includes a suction pipe 42, a collection box 43, a negative pressure pipe 44, and a negative pressure device 47. One end of the suction pipe 42 is fixed to the side wall of the dust collection hood 41 away from the arc-shaped clamp 21, and the other end of the suction pipe 42 passes through the operating table 11 and is located on the lower side of the operating table 11. The collection box 43 is fixedly connected to the bottom side wall of the operating table 11 and is located below the suction pipe 42. The negative pressure pipe 44 is installed on the side wall of the collection box 43, and the negative pressure device 47 is installed at the end of the negative pressure pipe 44 away from the collection box 43. When the negative pressure device 47 is running, the collection box 43 is in a negative pressure state due to the connection of the negative pressure pipe 44. Then, the dust collection hood 41 is in a negative pressure state through the suction pipe 42. Thus, the metal dust generated when the grinding disc 31 grinds the flange can be sucked through the dust collection hood 41 and transported to the collection box 43.

[0038] like Figures 1-3 As shown, a negative pressure hole is provided on the side wall of the receiving box 43, and an interception component is installed in the negative pressure hole. The interception component includes a first filter 45 and a second filter 46 installed sequentially in the negative pressure hole. The first filter 45 is located on the side closer to the inside of the receiving box 43. When the negative pressure device 47 provides negative pressure, it adsorbs the metal dust and then intercepts the metal dust in the receiving box 43 through the first filter 45 and the second filter 46.

[0039] It should be noted that in order to treat the metal dust generated during grinding by means of negative pressure suction, a negative pressure device 47 is required to provide the negative pressure for suctioning the metal dust. The negative pressure device 47 can be a vacuum machine or a blower or other negative pressure equipment. At the same time, the negative pressure device 47 is common knowledge in the field of dust collection. Therefore, the negative pressure device 47 used in this technical solution is existing technology and will not be described in detail here.

[0040] In use, rotating the bidirectional screw 26 drives the movement of a pair of sliders 24, which in turn moves a pair of arc-shaped clamping plates 21. These clamping plates 21 hold and fix the flange of the rotating flange, ensuring that the flange does not rotate during grinding. Rotating the adjusting screw 39 moves the mounting plate 37, adjusting the height of the grinding disc 31 so that it contacts the fixed flange surface. The rotation of the grinding disc 31 then enables rapid grinding of the flange. The grinding disc 31 generates heat during grinding, which is quickly absorbed by the phase change material 33. Multiple heat-conducting rods 35 conduct the heat absorbed by the phase change material 33 to multiple heat dissipation fins 34. The rotation of the multiple heat dissipation fins 34 driven by the grinding disc 31 quickly releases the heat to the outside, ensuring high heat dissipation efficiency when the grinding disc 31 grinds the flange, thereby improving the grinding efficiency and grinding effect of the grinding disc 31 on the flange. In addition, when the grinding disc 31 grinds the flange, the mounting plate 37 is opened simultaneously, so that the dust suction hood 41 is in a negative pressure state, so that the metal dust generated when the grinding disc 31 grinds the flange can be absorbed and treated by the dust suction hood 41, avoiding contact between the dust and the operators and ensuring the health of the operators.
