Detailed Description
The invention is further described with reference to the accompanying drawings.
Referring to fig. 1-6, the invention designs an elastic coupling for testing a servo motor, which comprises an end cover, a clamp body, an elastic jacket, an inner taper sleeve and a base, wherein a through hole is formed in the center of the base 1, a cylindrical pin 2 is inserted and fixed from the through hole of the base 1, four rectangular through grooves 3 which are rotationally symmetrical about the through hole are formed in the edge of the base 1, a clamping pin 5 is arranged at the bottom end of the clamp body 4, a pair of wedge-shaped insertion holes 13 which are opposite in position are formed in the center of the surface of the clamp body 4, and the clamp body 4 is fixed on the base 1 by matching and clamping the clamping pin 5 and the rectangular through grooves 3; one end of a disc spring 6 is fixed with a base 1, the other end of the disc spring 6 is fixed with the bottom surface of a mandril 7, the mandril 7 is sleeved on a cylindrical pin 2, a wedge-shaped groove 8 is formed in the longitudinal direction of the surface of the mandril 7, a rectangular groove is formed in the transverse direction of the surface of the mandril 7, a mounting key 9 is clamped in the rectangular groove, a pair of mounting holes 11 opposite in position are formed in the bottom end of an inner taper sleeve 10, a pair of wedge-shaped through holes 12 opposite in position are formed in the central position of the surface of the inner taper sleeve 10, the bottom end of the inner taper sleeve 10 is sleeved on the outer edges of the mandril 7 and the disc spring 6, the mounting key 9 is clamped in the mounting holes 11, the wedge-shaped groove 8 is communicated with the wedge-shaped through holes 12, the inner taper sleeve 10 is embedded inside a clamp body 4, so that the wedge-shaped, the middle upper part with the left thread is in threaded connection with the clamp body 4, then the end cover 15 is fixed at the top of the clamp body 4 through the screw, the base 1 is fixed at the bottom of the clamp body 4 through the fixing bolt, and therefore the elastic clamping sleeve 14, the inner conical sleeve 10, the ejector rod 7 and the disc spring 6 are fixed inside the clamp body 4.
In the invention, the inner taper sleeve 10 is in clearance fit with the elastic jacket 14 and the clamp body 4, so that the inner taper sleeve is in a sliding state between the elastic jacket and the clamp body.
According to the invention, the ejector rod 7 and the cylindrical pin 2 are in clearance fit, so that the ejector rod is in a sliding state.
The bottom surfaces of the wedge-shaped through hole 12, the wedge-shaped groove 8 and the wedge-shaped insertion hole 13 are all wedge-shaped surfaces which are inclined upwards.
In the clamping process, under the condition of no external force intervention, the belleville spring acts on the ejector rod, the ejector rod drives the key to further act on the inner conical sleeve, the inner conical sleeve is pushed towards the end cover, the inner cone of the inner conical sleeve acts on the outer conical surface of the elastic clamping sleeve, and the inner hole of the elastic clamping sleeve is gradually reduced and tightened to play a clamping role.
In the releasing process, referring to fig. 6, when the external wedges are symmetrically inserted, the external wedges act on the inner taper sleeve inclined plane and the ejector rod inclined plane simultaneously to push the two parts to the base direction along the axis, at this time, the inner taper sleeve gradually loses the constraint on the elastic jacket, and the elastic jacket restores the original shape to release and clamp due to the self elastic action.
