[0023] The following describes the embodiments and appendices. Figures 1-5 The technical solution of this utility model will be further described below.

[0024] Example 1

[0025] A flange surface treatment device includes: a worktable 1, a drive mechanism 2, and a fixing mechanism 3. The drive mechanism 2 includes a linear module 21 mounted on the worktable 1, a linear module 22 mounted on the upper side of the linear module 21, and a linear module 23 mounted on the linear module 22. A grinding motor 41 is mounted on the linear module 23, and a grinding disc 42 is mounted on the output end of the grinding motor 41. The fixing mechanism 3 includes a fixing base 31, an adjusting screw 32, a sliding block 33, and a positioning post 34. The fixing base 31 has a cavity 311 inside and a side... The sliding block 33 has a groove 312 that communicates with the cavity 311. The adjusting screw 32 is rotatably disposed in the cavity 311, and one end of the adjusting screw 32 passes through the side wall of the fixed seat 31 and is fixedly disposed with a rotating handle 321. The sliding block 33 has a U-shaped cross section. The lower end of the sliding block 33 is slidably disposed in the cavity 311 and is threadedly connected to the adjusting screw 32. The fixed seat 31 has a groove 313. The side end of the sliding block 33 is slidably disposed in the groove 312 and the upper end is slidably disposed in the groove 313. The positioning post 34 is disposed on the sliding block 33 for fixing the flange.

[0026] like Figures 1-5 As shown, in practical applications, this invention first places the flange to be processed on the fixed base 31, and precisely limits its position by inserting the positioning pin 34 into the flange hole. Then, the drive mechanism 2 is activated, and with the coordinated movement of linear modules 21, 22, and 23, the position of the grinding disc 42 is precisely controlled, allowing it to efficiently grind the flange surface along a preset trajectory. After grinding is complete, the grinding motor 41 is turned off, and the flange is removed for subsequent inspection or processing. The flexible movement of the small-sized grinding disc not only improves grinding efficiency but also avoids uneven wear of the grinding disc caused by different flange sizes, effectively extending the service life of the grinding disc.

[0027] This utility model is equipped with at least two sets of symmetrical fixing mechanisms 3. By rotating the rotary handle 321, the adjusting screw 32 can be driven to rotate, thereby adjusting the position of the sliding block 33 and the positioning pin 34 to accommodate flanges of different sizes. The slide groove 312 is located at the side end of the fixed seat 31 and cooperates with the U-shaped sliding block 33, effectively preventing waste from entering the interior of the fixed seat 31, preventing waste from accumulating in the cavity 311, ensuring smooth rotation of the adjusting screw 32, and ensuring the accuracy of the position adjustment of the positioning pin 34.

[0028] As a further preferred embodiment, the upper end of the sliding block 33 is provided with a threaded mounting hole 331, and the lower end of the positioning post 34 is provided with a threaded post 341. The positioning post 34 is threadedly mounted in the threaded mounting hole 331 of the sliding block 33 through the threaded post 341.

[0029] Specifically, the positioning pin 34 is connected to the threaded mounting hole 331 of the sliding block 33 via the threaded pin 341 to ensure a secure installation; the positioning pin 34 can be replaced with a suitable one according to the flange model to meet different specifications and facilitate replacement and maintenance.

[0030] As a further preferred embodiment, the linear module 21 includes a reciprocating screw 211 rotatably disposed at the lower end of the worktable 1, a translation seat 212 threadedly connected to the reciprocating screw 211, a drive motor 213 drivenly connected to one end of the reciprocating screw 211, and a mounting bracket 214 disposed on the translation seat 212. The linear module 22 includes a reciprocating screw 221 rotatably disposed at the upper end of the mounting bracket 214, a translation seat 222 threadedly connected to the reciprocating screw 221, and a drive motor 213 drivenly connected to one end of the reciprocating screw 221. The second drive motor 223 and the first mounting plate 224 are mounted on the second translation seat 222. The third linear module 23 includes a slide 231 mounted on the upper and lower ends of the first mounting plate 224, a second mounting plate 232 slidably mounted on the slide 231, a rack 233 mounted on the second mounting plate 232, and a drive motor 234 mounted on the first mounting plate 224. The output end of the drive motor 234 meshes with the rack 233 through transmission teeth to drive the second mounting plate 232 to rise and fall. The grinding motor 41 is located at the lower end of the second mounting plate 232.

[0031] Specifically, during operation, drive motor 213 and sliding seat 212 work together to drive the entire linear module 22 to move horizontally along the X-axis. Drive motor 223 and sliding seat 222 work together to drive linear module 3 to move horizontally along the Y-axis. Drive motor 324, through rack and pinion 233, causes mounting plate 232 to rise and fall vertically along the Z-axis. This design achieves precise position control in three-dimensional space, ensuring that the grinding disc 42 can perform comprehensive and efficient grinding on the flange surface according to a predetermined trajectory.

[0032] As a further preferred embodiment, guide rails 11 are provided on both sides of the workbench 1, and a sliding bearing 2141 is provided on the inner side of the mounting bracket 214. The sliding bearing 2141 is slidably mounted on the guide rails 11.

[0033] Specifically, the cooperative arrangement of the sliding bearing 2141 and the guide rail 11 ensures the stable movement of the mounting bracket 214 in the horizontal direction, reduces shaking and deviation during movement, and improves the overall stability and accuracy of the device.

[0034] As a further preferred embodiment, a dust suction hood 411 is fitted onto the lower end of the grinding motor 41, and the side end of the dust suction hood 411 is connected to the dust suction pipe.

[0035] Specifically, the dust hood 411 can effectively collect the waste and dust generated during the polishing process, keep the working environment clean, reduce the harm of dust to the health of operators, and improve the overall efficiency and quality of polishing operations.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
