DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0021] Embodiment 1: An angle-adjustable shaft straightening machine, see Figures 1 to 5, including a processing frame 1, a driving motor 2 is installed at one end of the processing frame 1, a connecting rod 3 is installed at the driving end of the driving motor 2, a connecting tube 31 is sleeved on the outer side of the connecting rod 3, a spring 32 is fixedly connected between the connecting tube 31 and the connecting rod 3, limiting grooves 33 are provided on both sides of the inner cavity of the connecting tube 31, and limiting blocks 34 are slidably connected in the two limiting grooves 33, and the two limiting blocks 34 are fixedly connected to the connecting rod 3, and a limiting mechanism 4 is installed at one end of the connecting tube 31, and the limiting mechanism 4 includes a spring 32 installed on the connecting tube 31. A connecting plate 41 is provided with an adjustment groove 45 at one end of the connecting plate 41 away from the connecting tube 31, and a bidirectional screw rod 42 is rotatably connected between the two sides of the inner cavity of the adjustment groove 45. Two adjustment blocks 43 are slidably connected in the adjustment groove 45, and the two adjustment blocks 43 are both threadedly sleeved on the outer side of the bidirectional screw rod 42. A V-shaped clamping plate 44 is fixedly connected to the two adjustment blocks 43. A connecting shaft 7 is rotatably connected to the end of the inner cavity of the processing frame 1 away from the connecting rod 3, and a connecting disk 71 is fixedly connected to the connecting shaft 7. The center of the limiting mechanism 4 is connected to the connecting rod 3. The centers of the disks 71 are on the same horizontal line. A supporting mechanism 5 is installed at the bottom of the inner cavity of the processing frame 1. The supporting mechanism 5 includes a column 51. A V-shaped supporting plate 53 is fixedly connected to the top of the column 51. The shaft rod to be straightened is supported by the V-shaped supporting plate 53. Then, the connecting plate 41 is turned to compress the spring 32. Then, the two ends of the shaft rod correspond to the connecting plate 41 and the connecting disk 71 respectively. Then, the elastic force of the spring 32 pushes the limiting mechanism 4 to limit the shaft rod between the limiting mechanism 4 and the connecting disk 71. At the same time, the double The rotation of the screw rod 42 drives the V-shaped clamping plate 44 to move relative to each other, thereby limiting one end of the shaft rod. When the shaft rod is squeezed and straightened, the connecting tube 31 is sleeved on the outside of the connecting rod 3 and cooperates with the spring 32 to ensure that the shaft rod is straightened. At the same time, the shaft rod is prevented from rotating during straightening and affecting the straightening effect of the shaft rod.
