The base 1 is provided with a T-shaped groove, the supporting seat 2 is fixed on the bottom plate 1 by bolts when in use, and the mounting position of the supporting seat can be adjusted according to actual conditions.
One end of the spline shaft 3 is an internal spline and is used for being matched with an output spline which needs to be fixed by a product, and the other end of the spline shaft is provided with a cylindrical pin shaft which has no angular relation with the internal spline. The collar 4 is provided with a cross groove, when the spline shaft 3 is installed, after the cylindrical pin passes through the cross groove through hole completely, the collar 4 is rotated for half circle, the spline shaft 3 is pulled outwards, the cylindrical pin is clamped into a blind groove in the cross groove, the combined body is embedded into a V-shaped groove in the supporting seat 2, and the spline shaft 3 is limited to move along the X, Y shaft direction and rotate around the Y, Z shaft.
If the product is a single spline output, the position of the support base 2 on the base plate 1 can be determined first, and the support base 2 is fixed by bolts. After the spline shaft 3 and the clamping ring 4 are installed and embedded into the V-shaped groove in the supporting seat 2, the output spline end of the product is sleeved on the spline shaft 3, and because of the angular relation between the two splines, the angle of the spline shaft 3 or the product can be selectively adjusted according to the requirement to meet the matching requirement.
On the basis of the above-mentioned assembled design, if the product is a double spline output, two support bases 2 can be symmetrically placed on the bottom plate 1, the position of one of the support bases 2 on the bottom plate 1 is determined first, and the support bases 2 are fixed by bolts. After the two groups of spline shafts 3 and the clamping rings 4 are installed and respectively embedded into the V-shaped grooves in the supporting seat 2, two output spline ends of the product are respectively sleeved on the spline shafts 3, because of the angular relation between the matched splines, the angles of the spline shafts 3 or the product can be selectively adjusted according to the needs to meet the matching requirements, and finally the other supporting seat 2 is fixed.
