After the spline fluted disc 6 is sleeved at the spline end of the spline shaft yoke 9, the central line of the keyway 61 is superposed with the central line of the spline shaft yoke 9. One side of the spline fluted disc 6 is also provided with a measuring block 62, and the top surface of the measuring block 62 is parallel to the central line of the key groove 61, so that the inclination of the spline central line of the spline shaft fork 9 can be obtained by measuring the inclination of the top surface of the measuring block 62.

The first support seat 2 and the spindle 5 are used for supporting the lug end of the spline shaft yoke 9. The spindle 5 is inserted into and penetrates through the ear hole of the spline shaft yoke 9, and as shown in fig. 4, in order to facilitate the insertion of the spindle 5 into the ear hole of the spline shaft yoke 9, one end of the spindle 5 is provided with a handle 52 extending from the end surface. And the end of the mandrel 5 is provided with a snap ring 51 protruding towards the outer side surface, and the other end of the mandrel 5 is detachably sleeved with a transition sleeve 53. When the mandrel 5 is installed on the spline shaft yoke 9, the mandrel 5 is firstly inserted from one end of the ear hole end of the spline shaft yoke 9, then the transition sleeve 53 is sleeved on the mandrel 5 at the other side of the ear hole end of the spline shaft yoke 9, and the ear hole end of the spline shaft yoke 9 is fixed between the snap ring 51 and the transition sleeve 53.

The first supporting seat 2 is fixed on the bottom plate 1, and as shown in fig. 6, an accommodating groove 21 is formed in the center of the top of the first supporting seat 2, and first supporting grooves 22 are formed at two ends of the top of the first supporting seat 2 respectively. When the lug end of the spline shaft yoke 9 is placed on the first support seat 2, the lug end of the spline shaft yoke 9 is received in the receiving groove 21, and the snap ring 51 and the transition sleeve 53 of the spindle 5 rest in the first support grooves 22 at both ends, respectively, for supporting the lug end of the spline shaft yoke 9.
