In FIGS. 1-3: the connecting cylinder 1, the ball disc 101, the balls 102, the positioning holes 103, the springs 1031, the locking clamping grooves 104, the guide rod 2, the spindle 3 and the limiting strips 301.
Detailed Description
Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b):
referring to figures 1-3 of the drawings,
the mechanical direct-connection main shaft provided by the embodiment comprises a connecting cylinder 1, a ball disc 101 is fixedly arranged on the right side inside the connecting cylinder 1, balls 102 are arranged in the ball disc 101 in an embedded mode, a positioning hole 103 is formed in the right side inside the connecting cylinder 1, a spring 1031 is fixedly arranged inside the positioning hole 103, the bottom end of the spring 1031 and the outer side of the ball disc 101 are fixedly installed through bolts, a locking clamping groove 104 is formed in an inner wall opening on the right side of the connecting cylinder 1, a guide rod 2 is also fixedly arranged on the right side of the connecting cylinder 1, a main shaft 3 is fixedly arranged on the left side of the connecting cylinder 1, and a limiting strip 301 is.
Furthermore, the balls 102 are uniformly arranged in the ball disc 101 in a "circular ring" shape, and the balls 102 uniformly arranged in the ball disc 101 in a "circular ring" shape effectively controls the condition that a large amount of noise and vibration are generated when the connecting cylinder 1 and the guide rod 2 are in contact with a contact surface during high-speed operation.
Further, the diameter of the opening of the positioning hole 103 is slightly larger than the diameter of the spring 1031 by one millimeter, and the length of the positioning hole 103 is one centimeter, so that the spring 1031 can absorb the slight vibration of the guide rod 2 in the positioning hole 103, and the rotation source is not easily damaged.
Further, two springs 1031 are disposed at the upper and lower ends of the ball tray 101, respectively, so that the springs 1031 prevent the guide bar 2 from tilting greatly when the guide bar is rotated for use.
Furthermore, the left side and the right side of the connecting cylinder 1 both use the opening which is matched with the guide rod 2 and the main shaft 3, so that the condition that the main shaft 3 is scrapped due to the fact that the conventional mechanical direct-connection main shaft is easy to loosen or deform is avoided.
Further, spacing 301 and locking groove 104 coincide each other, and spacing 301 and locking groove 104 contact surface all are equipped with anti-skidding line, coincide each other with locking groove 104 of connecting cylinder 1 right side inner wall through spacing 301 in the main shaft 3 outside and fix, can prevent that main shaft 3 from rotating and droing.
The working principle is as follows:
when the mechanical direct-coupled spindle provided by this embodiment is used, firstly, the balls 102 uniformly arranged in a "circular ring" shape in the ball tray 101 effectively control the condition that a large amount of noise and vibration are generated when the connecting cylinder 1 and the guide rod 2 are in contact with a contact surface during high-speed operation, then the spring 1031 absorbs the slight vibration of the guide rod 2 in the positioning hole 103, so that the rotation source itself is not easily damaged, and meanwhile, the guide rod 2 is prevented from being largely inclined during rotation use, and simultaneously, the connecting cylinder 1 and the guide rod 2 are effectively controlled to generate a large amount of noise and vibration during high-speed operation and contact with the contact surface, and the spring 1031 fixedly arranged in the positioning hole 103 can self-adaptively adjust the horizontal direction of the guide rod 2 during rotation of the connecting cylinder 1, so as to prevent the guide rod 2 from largely inclining in the connecting cylinder 1, and at this time, the limit strip 301 outside the spindle 3 is mutually matched and fixed with the locking slot 104 on the right side inner wall of the connecting cylinder 1, can prevent that main shaft 3 from rotating to drop, avoid in the past that mechanical direct-connected main shaft is easily loose or warp and arouse the condemned condition of main shaft 3, dismouting change that simultaneously can be quick adapts to the different main shaft 3 of unidimensional for the routine maintenance and the repair of this mechanical direct-connected main shaft become more swift, can improve the atress degree of this mechanical direct-connected main shaft simultaneously.
