Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, the universal adjusting tensioning mechanism comprises a base 5 and a movable motor seat plate 3, three struts are arranged between the base 5 and the motor seat plate 3, the three struts are arranged in a triangular structure, the lower parts of the struts are connected with the base 5, the upper parts of the struts penetrate through the motor seat plate 3, spherical pair mechanisms are respectively arranged between the struts and the motor seat plate 3, each spherical pair mechanism comprises two hemispherical gaskets 2 and two hemispherical nuts 1, the two hemispherical gaskets 2 penetrate through the struts and are respectively arranged on the upper side and the lower side of the motor seat plate 3, and the two hemispherical gaskets 2 are respectively fixed through the hemispherical nuts 1; the pillar comprises an adjusting upright post 6, threads are arranged on the adjusting upright post 6, a fixed upright post 4 is installed on the lower portion of the adjusting upright post 6, and the fixed upright post 4 is matched with the machine base 5.

As shown in fig. 4 and 5, the working principle of the present invention is as follows: because when changing the motor band pulley, if want to realize the tensioning operation through upset motor bedplate 3, need to guarantee that the axis of rotation of motor bedplate 3 is parallel with motor rotation axis 8 axis and driven pulley 9 axis. Therefore, two struts are combined into a group, the two spherical pair mechanisms are formed into 2 revolute pairs by respectively limiting the heights of the two spherical pair mechanisms, so that the rotation axis of the motor seat plate 3 is limited, the rotation axis of the motor seat plate 3 is parallel to the axis of the driven pulley 9, and meanwhile, the axis of the motor rotating shaft 8 is parallel to the rotation axis of the motor seat plate 3 by adjusting the installation position of the motor on the motor seat plate 3, so that the axis of the motor rotating shaft 8 is parallel to the axis of the driven pulley 9 when the motor seat plate 3 is turned over; the third pillar 12 is another group, sets up rectangular hole between third pillar 12 and the motor bedplate 3, the adjusting position of being convenient for, and this department's sphere pair mechanism forms 1 cylinder pair, and the fixed upright 4 of third pillar 12 is the shortest, and adjusting upright 6 is the longest to for the sphere pair mechanism reciprocates and provides great activity space, through the height of adjusting the sphere pair mechanism on the third pillar 12, make it realize drive belt's tensioning.
