DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] Reference Figure 1-7 As shown, an aluminum alloy surface treatment device includes a processing box 1 and a grinding mechanism 2. The box walls on both sides of the processing box 1 are provided with circular processing openings 11. The grinding mechanism 2 is installed in the processing box 1 for grinding the tube wall of the aluminum alloy pipe fitting. The outer walls on both sides of the processing box 1 and located directly below the processing openings 11 are connected with fixed plates 12. Each of the fixed plates 12 is installed with a clamping mechanism 3 for clamping the aluminum alloy pipe fitting.

[0026] In this embodiment, the grinding mechanism 2 includes an annular seat 31 and a cylinder 23. Two mounting plates 211 are connected to the inner wall of the processing box 1. The two mounting plates 211 are connected to the annular seat 31. An annular slide rail 22 is connected to the inner ring surface of the annular seat 31. A rotating ring 221 is slidably connected to the annular slide rail 22. The cylinder 23 is installed on the rotating ring 221. The movable end of the cylinder 23 is connected to a U-shaped connecting frame 24. A motor 25 is installed on the connecting frame 24. The two ends of the connecting frame 24 are rotatably connected to a rotating shaft. A grinding roller 26 is coaxially connected to the rotating shaft. The output shaft of the motor 25 is coaxially connected to the rotating shaft. The annular seat 31 and the processing port 11 are located on the same axis.

[0027] In this embodiment, a first connecting plate 271 is connected to a side of the connecting frame 24 away from the motor 25, a second connecting plate 272 is connected to the rotating ring 221, the first connecting plate 271 is rotatably connected to the main shaft 27, an end of the rotating shaft away from the motor 25 is coaxially connected to a first bevel gear 261, a lower end of the main shaft 27 is coaxially connected to a second bevel gear 274, the first bevel gear 261 is meshed with the second bevel gear 274, the second connecting plate 272 is rotatably connected to a rotating seat 273, the rotating seat 273 is slidably connected to the main shaft 27, a third bevel gear 275 is coaxially connected to the rotating seat 273, an annular gear ring 28 is coaxially connected to the annular seat 31, and the gear ring 28 is meshed with the third bevel gear 275.

[0028] In this embodiment, the clamping mechanism 3 includes an annular seat 31 and a rotating sleeve 35. The annular seat 31 is installed on the fixed plate 12. The annular seat 31 is coaxially rotatably connected with the rotating sleeve 35. Three movable grooves 32 are provided on the side of the annular seat 31 close to the rotating sleeve 35. The three movable grooves 32 are distributed in an annular array. A movable block 33 is slidably connected in each of the movable grooves 32. One end of each movable block 33 close to the inner ring of the annular seat 31 is rotatably connected to a pair of clamping rollers 34 through a pin shaft. Three arc-shaped guide grooves 36 are provided on the rotating sleeve 35. Each of the movable blocks 33 is connected to a guide rod 37. The three guide rods 37 are respectively slidably connected to the three guide grooves 36. The outer ring of the rotating sleeve 35 is threadedly connected to a fastening screw 38. A rocker 39 is coaxially connected to the fastening screw 38. The annular seat 31 and the processing opening 11 are located on the same axis, so that the annular seat 31 and the fixed ring 21 are coaxially arranged.

[0029] In this embodiment, the wheel surface of the clamping roller 34 is made of rubber material, and the higher friction coefficient of the rubber material is used to increase the friction force when clamping the aluminum alloy pipe.

[0030] The working process and principle of the present invention are as follows:

[0031] When using, Figure 8 As shown, one end of the aluminum alloy pipe is placed in the clamping mechanism 3, and passes through the two processing ports 11 of the processing box 1 and is placed in the clamping mechanism 3 on the other side. Then, the rocking wheels 39 on the two clamping mechanisms 3 are rotated to drive the rotating sleeve 35 to rotate, and the guide groove 36 is used to push the guide rod 37, so that the three moving blocks 33 move toward the center at the same time to control the three pairs of clamping rollers 34 to clamp the pipe. Then, the rocking wheel 39 is turned to drive the fastening bolts 38 to rotate, so that the rotating sleeve 35 is fixed on the annular seat 31. After the clamping is completed, the aluminum alloy pipe is located on the same axis as the fixing ring 21. At this time, according to the diameter of the pipe, the cylinder 23 is controlled to push the grinding roller 26 close to the pipe. After the position of the grinding roller 26 is adjusted, the motor 25 is turned on. After the motor 25 is turned on, it drives the grinding roller 26 to rotate at a high speed. At the same time, the meshing of the first bevel gear 261 and the second bevel gear 274 and the third bevel gear 275 and the ring gear 28 Under the cooperative effect, the entire rotating ring 221 rotates at a low speed on the annular slide rail 22, so that the grinding roller 26 rotates at a high speed while revolving around the pipe fitting to grind the outer surface of the pipe fitting. During the grinding process, the pipe fitting is pushed horizontally at a constant speed from the other end (it can be pushed manually or by external equipment such as a cylinder). As the pipe fitting moves horizontally, the grinding roller 26 will grind the entire pipe fitting, and the metal scraps generated during the grinding process will be blocked by the processing box 1 and will not splash everywhere. As the pipe fitting is pushed, when one end of the pipe fitting is separated from the clamping mechanism 3, the clamping mechanism 3 on one side still clamps the pipe fitting, and the pipe fitting will not fall off. At the same time, the situation that the clamping position of the pipe fitting cannot be polished is avoided. To ensure the grinding effect, after one end of the pipe fitting is fully extended into the processing box 1 for grinding, the pipe fitting can be pushed in the opposite direction from the other side, so that the grinding roller 26 performs a reciprocating grinding on the pipe fitting.

[0032] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
