The output end of the grinding drive 41 is connected to the driving wheel 42, and the grinding belt 44 is wound around the driving wheel 42 and the outer periphery of the two driven wheels 46.

The grinding drive 41 can be a motor, and the output end of the motor is connected to the driving wheel 42.

[0037] Since the active support 43 is connected to the support frame 12, the upper end of the driven support 47 is slidably connected to the active support 43, and the lower end of the driven support 47 is connected to the bearing mechanism 2, so that the two driven supports 47 can move with the bearing mechanism 2, so that the horizontal distance between the two bearing mechanisms 2 below the workpiece is adjusted, and the horizontal distance between the two driven wheels 46 is also changed, so as to better realize the grinding of the weld on the workpiece, optimize the grinding effect, and help to improve the adjustability, so as to be suitable for tubular workpieces of different diameters.

The two screw nuts 33 are both screwed to the lead screw 32, and the rotation of the lead screw 32 can drive the two screw nuts 33 to move toward or away from each other. The horizontal driving member 31 can accurately control the rotation of the lead screw 32, thereby driving the two screw nuts 33 to achieve synchronous movement toward or away from each other, so that the two bearing mechanisms 2 can be accurately adjusted in the horizontal direction, so that the horizontal distance can be adjusted according to the diameter of the workpiece, and the two bearing mechanisms 2 are always symmetrically located on both sides of the axis of the workpiece, thereby improving the support stability of the workpiece. The axis of the lead screw 32 is parallel to the distribution direction of the two bearing mechanisms 2, which can ensure the stability of the movement, reduce the error caused by the offset, and help improve the working efficiency and grinding quality of the equipment.

The base 11 is used to support the lifting drive member 212 and the bearing member 213, and the base member 211 is slidably connected to the base 11, so that the bearing mechanism 2 can move freely on the base 11, which is convenient for adjusting the position of the workpiece. The lifting drive member 212 is used to adjust the height of the bearing member 213, thereby realizing the adjustment of the height of the conveying roller 23, so that the vertical distance between the conveying roller 23 below the workpiece and the grinding belt 44 above the workpiece can be adjusted according to the diameter of the workpiece, thereby improving the applicability to workpieces of different diameters, and enhancing the scope of application and operational flexibility of the equipment. The base member 211 may be a block structure with a cavity, so that the lifting drive member 212 is arranged in the cavity; the lifting drive member 212 may be a structure capable of achieving extension and retraction, such as a cylinder, a hydraulic cylinder or an electric telescopic rod; the bearing member 213 may be a plate structure.

[0041] Optionally, the cross section of the conveying roller 23 along its own axis direction is an isosceles trapezoid, and the two conveying rollers 23 are symmetrically arranged on both sides of the workpiece conveying direction, so that the horizontal distance between the small end faces of the two conveying rollers 23 is smaller than the horizontal distance between the large end faces of the two conveying rollers 23. While supporting the tubular workpiece in the vertical direction, the conveying rollers 23 can also limit the rolling of the tubular workpiece, improve the stability of the workpiece bearing, reduce the deviation of the workpiece caused by vibration during the grinding process, and ensure the grinding quality.

[0042] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the device also includes a vertical moving mechanism 5, which includes a cam 51, a vertical driving member 52 and an elastic member 53. The support mechanism 1 includes a top plate 13, which is connected to the top of the support frame 12, and an active support member 43 is arranged below the top plate 13, and the active support member 43 is vertically spaced from the top plate 13. Both sides of the active support member 43 are slidably connected to the support frame 12, the vertical driving member 52 is connected to the support frame 12, the output end of the vertical driving member 52 is transmission-connected to the cam 51, and the two ends of the elastic member 53 are respectively connected to the lower side of the top plate 13 and the upper side of the active support member 43, so that the active support member 43 is always in contact with the outer peripheral surface of the cam 51, and the rotation of the cam 51 can drive the active support member 43 to move vertically, and the driven support member 47 is vertically plugged into the bearing mechanism 2. The coordinated use of the cam 51 and the vertical drive member 52 enables the active support member 43 to move in the vertical direction, and the elastic member 53 enables the active support member 43 to always keep in contact with the outer peripheral surface of the cam 51, thereby ensuring the stability and reliability of the moving process. Through the height adjustment of the grinding mechanism 4, the equipment can make the grinding belt 44 rise a certain distance when the grinding of a tubular workpiece is completed and the next tubular workpiece needs to be ground, thereby reducing the risk of interference between the grinding belt 44 and the end of the workpiece, thereby improving the smoothness of the grinding process.

One end of the telescopic limiter 54 is connected to the lower side of the top plate 13, and the other end of the telescopic limiter 54 is used to push the upper side of the active support member 43. When the cam 51 pushes the active support member 43 to move upward, the telescopic limiter 54 retracts. When the equipment is grinding the weld of the same section of the workpiece, the telescopic limiter 54 can maintain the pushing and pressing down of the active support member 43, ensure that the grinding belt 44 applies sufficient pressure to the workpiece, and improve the grinding effect. When the workpiece is replaced, the telescopic limiter 54 retracts so that the active support member 43 can be moved upward, and the grinding belt 44 is placed on the upper side of the next workpiece to ensure the reliable grinding of the weld.

The lower end area of ​​the guide groove is smaller than the upper end area of ​​the guide groove, and the guide block 471 cooperates with the guide groove, so that the driven support 47 can rise or fall smoothly along the guide groove, reducing the difficulty of plugging, making the relative position between the driven support 47 and the bearing mechanism 2 more accurate, thereby improving the grinding accuracy and stability. The guide groove includes a vertical surface, so that sufficient horizontal driving force can be applied to the guide block 471. The minimum horizontal distance between the two conveying rollers 23 is smaller than the minimum horizontal distance between the two inserts 24, which can reduce the risk of the insert 24 interfering with the conveying of the tubular workpiece during the conveying of the tubular workpiece by the conveying roller 23, and improve the reliability and smoothness of the conveying and grinding of the workpiece.
