[0026] like Figure 1-Figure 2 As shown, the utility model adopts gray iron HT300 casting to form the bed, with a length of 2500mm, a bed width of 500mm, and a height of 900mm from the bed to the ground. The lower surface of the bed 1 is a plane, and the upper surface is a triangular bed surface to ensure the straightness of the top tailstock 2 when moving on the bed surface. The bed surface adopts high-frequency induction quenching to increase wear resistance. The two legs 4 at the bottom of the bed 1 are also cast with gray iron to maintain the stability of the deflection meter.

[0027] like Figure 3-Figure 4 As shown, two top tailstocks 2 are installed at both ends of the bed 1; the top tailstock 2 includes a pointed head 21, a sleeve 22, a handwheel 23, and a seat 24. The sleeve 22 is installed at the head of the seat 24, the pointed head 21 is installed on the sleeve 22, the handwheel 23 is installed at the tail of the seat 24, and the handwheel 23 is connected to the sleeve 22 through a screw transmission. In order to prevent the top tailstock 2 from moving, a set of clamping mechanisms 5 are designed on the side of the top tailstock 2. The upper end of the clamping mechanism 5 is connected to the top tailstock 2, and the lower end has a locking bolt, which is fixed to the side of the bed 1. The left top tailstock 2 is usually fixed, and the locking bolt of the clamping mechanism 5 of the right top tailstock 2 is adjusted to improve the detection efficiency. A movable sleeve 22 is provided in the middle of the top tailstock 2, and the position of the pointed head 21 is moved by the handwheel 23 and the screw to achieve the measurement purpose.

[0028] like Figure 5-Figure 6As shown, the lifting device 3 is located below the shaft body 6, and includes an upper clamping plate 31, a lower clamping plate 32 and an anti-drop frame 33. The upper clamping plate 31 and the lower clamping plate 32 are connected by a fastener 34. When the fastener 34 is loosened or tightened, the lifting device 3 can slide or be fixed on the bed 1; the anti-drop frame 33 includes a threaded rod 331 and a V-shaped block 332. The V-shaped block 332 is fixed on the top of the threaded rod 331, and the bottom of the threaded rod 331 is threadedly connected to the clamping plate. The utility model additionally designs a set of lifting devices 3 that can adjust the position and height.
