[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 The present invention provides a technical solution: including a base plate 1, and a fixing mechanism 2 and a beveling mechanism 3 are provided on the top of the base plate 1;

[0029] The fixing mechanism 2 includes a fixing part and a cleaning part;

[0030] The fixing part includes a rotating sleeve 22 and two clamping rings 29, and the cleaning part includes a cleaning brush 26 and a squeezing frame 27;

[0031] A base 23 is fixedly mounted on the top surface of the base plate 1. The inner side of the base 23 is slidably connected to the outer wall of the rotating sleeve 22. Two clamping rings 29 are located inside the rotating sleeve 22. Two through slots are opened on the outer wall of the rotating sleeve 22. A control ring 210 is slidably mounted on the outer wall of the rotating sleeve 22. Two connecting plates 28 are respectively provided on the inner walls of the two through slots. The inner side of the control ring 210 is hinged to the outer wall of the two connecting plates 28. The side of the two connecting plates 28 near the two clamping rings 29 is hinged to the outer wall of the two clamping rings 29. The top surface of the extrusion frame 27 slides through the bottom surface of the base plate 1 and extends to the top of the base plate 1. The top surface of the extrusion frame 27 is fixedly connected to the bottom surface of the cleaning brush 26. A motor 21 is fixedly mounted on the top surface of the base plate 1. Two pulleys 25 are fixedly mounted on the outer wall of the output end of the motor 21 and the outer wall of the rotating sleeve 22, respectively. The pulleys 25 are connected by belt drive. The outer wall of the rotating sleeve 22 is fixedly fitted with a ring rail 24. The outer wall of the ring rail 24 is slidably connected to the inner side of the base 23. The outer wall of the rotating sleeve 22 is fixedly fitted with a fixed frame 213. The outer wall of the fixed frame 213 is slidably connected to the inner side of the control ring 210. The outer wall of the fixed frame 213 is threaded through a pressing screw 212 extending to the inner side of the fixed frame 213. The outer walls of the two clamping rings 29 are respectively fixedly fitted with two limiting plates 211. The two limiting plates 211 slide through the inner side of the rotating sleeve 22 and extend to the outer side of the rotating sleeve 22. The inner side of the pressing frame 27 is fixedly fitted with a spring 215 and a damper 216. The top surfaces of the spring 215 and the damper 216 are fixedly connected to the bottom surface of the base plate 1. The spring 215 is initially in the extended state.

[0032] The beveling mechanism 3 includes a fixed frame 31. The outer wall of the fixed frame 31 is fixedly connected to the outer wall of the base plate 1. An electric telescopic rod 34 is fixedly installed on the top surface of the fixed frame 31. The bottom surface of the output end of the electric telescopic rod 34 extends through the top surface of the fixed frame 31 to the inner side of the fixed frame 31. A mounting plate 32 is fixedly installed on the bottom surface of the output end of the electric telescopic rod 34. A beveling cutter 33 is installed on the bottom surface of the mounting plate 32. The bottom surface of the mounting plate 32 is bolted to the top surface of the beveling cutter 33 by multiple bolts.

[0033] In use, first place the elbow between the two clamping rings 29, then manually rotate the extrusion screw 212. The extrusion screw 212 moves within the fixed frame 213, pushing the control ring 210 to slide along the outer wall of the rotating sleeve 22. Since the inner side of the control ring 210 is hinged to the connecting plate 28, and the connecting plate 28 is hinged to the clamping rings 29, the sliding of the control ring 210 causes the connecting plate 28 to swing, making the two clamping rings 29 move closer to each other, thereby clamping and fixing the elbow. After fixing is completed, start the motor 21. The output end of the motor 21 drives the pulley 25 fixedly connected to it to rotate. Through belt transmission, the pulley 25 on the outer wall of the rotating sleeve 22 rotates accordingly, thereby driving the rotating sleeve 22 to rotate on the inner side of the base 23. When the rotating sleeve 22 rotates, the ring rail 24 on the outer wall of the rotating sleeve 22 slides on the inner side of the base 23, ensuring the stability of the rotation of the rotating sleeve 22.

[0034] Since the spring 215 is initially in an extended state, when the elbow is placed and pressed down by the clamping ring 29, the top surface of the extrusion frame 27 is subjected to pressure and slides down along the top surface of the base plate 1, causing the cleaning brush 26 to come into close contact with the elbow surface. During the rotation of the elbow, the cleaning brush 26 cleans impurities, dust and other contaminants from the elbow surface.

[0035] After the elbow is fixed, the beveling process begins. The electric telescopic rod 34 is activated, and its output end drives the mounting plate 32 to move downward. The beveling cutter 33, which is fixed to the mounting plate 32 by bolts, descends to the appropriate position. Once the beveling cutter 33 reaches the designated position, the elbow is beveling under the control of the CNC system. During the process, the fixed elbow can rotate under the drive of the rotating sleeve 22, allowing the beveling cutter 33 to perform uniform beveling on the circumferential surface of the elbow. This completes the beveling work of the multi-functional CNC elbow beveling machine. The elbow can also be cleaned during the beveling process using the cleaning brush 26.
