Based on the above technical scheme, a degree of freedom conversion hole is formed in the side surface of the rotary ball core 2, and a degree of freedom conversion pin 5 is arranged on the shell 4, so that when the degree of freedom conversion pin 5 is inserted into the degree of freedom conversion hole of the rotary ball core 2, the rotary ball core 2 can be limited from swinging in other directions except the front and back direction, and the rotary ball core 2 can only tilt back and forth relative to the positioning rod 14 by taking the degree of freedom conversion pin 5 as an axis. The freedom degree conversion pin 5 is screwed to be inserted into the freedom degree conversion hole of the rotary ball core 2, and then the ball joint mechanism can be converted from three-freedom-degree movement to two-freedom-degree movement by the plane rotation mechanism 8. And vice versa.
Still further, a core lock block 3 is provided between the housing 4 and the rotary core 2, and a core lock bolt 19 capable of pushing the core lock block 3 toward the rotary core 2 is provided on the housing 4. By tightening the core locking bolt 19 and loosening the locking screw 17, the rotary core 2 can be fixed at a certain position, and then the shell 4 is rotated, so that one-degree-of-freedom rotation of the ball joint structure can be realized by means of the plane rotating mechanism 8.
In the present embodiment, the damper 11 is preferably a spring damper, and to achieve the function that the position of the positioning rod 14 in the axial hole of the housing 2 can be adjusted up and down and locked, a worm gear, a wedge mechanism, a cam mechanism, or a rack and pinion mechanism may be employed. In the embodiment, a worm gear and a worm are adopted, that is, the positioning rod 14 is designed as a worm, the lower part of the shell 4 is provided with a worm gear box 7, a worm gear 6 meshed with the worm is arranged in the worm gear box 7, a worm gear transmission rod 20 connected with the worm gear 6 is arranged outside the worm gear box 7, and the position of the worm in the shell 4 can be adjusted up and down by rotating the worm gear transmission rod 20.

The position of the positioning rod 14 in the shaft hole of the shell can be adjusted up and down and can be locked, so that the position of a coupling point between the universal coupling 12 and the lower end part of the damper 11 can be changed, the damping size or the damping existence of the damper 11 can be changed by the change of the position of the coupling point, and the ball joint can be switched to a damping state or a non-damping state according to the requirement when the ball joint moves in three degrees of freedom.
The working principle and mode of the damper will be described in detail with reference to fig. 1, 2 and 6:
damping generation mode
As shown in fig. 1, 2, and 6, when the positioning rod 14 is adjusted up and down in the axial hole of the housing 4, the damper 11 is in a damping state without causing the movable joint of the universal joint 12 to coincide with the center point of the rotary spherical core 2 or causing the stopper pin 18 at the lower end of the positioning rod 14 to contact the base 9. When the docking platform 1 moves, the platform screw 10 drives the damper 11 to swing outwards around the movable node of the universal coupling 12, and the distance between the joint of the platform screw 10 and the upper end of the damper 11 and the movable node of the universal coupling 12 at the lower end of the damper 11 changes, so that the damper 11 generates a reverse elastic force, and the docking platform 1 obtains a reverse damping force.
Second, adjusting mode of damping force
As shown in fig. 2 and 6, the worm gear transmission rod 20 is twisted to drive the worm 14 to vertically move up and down, so as to change the position distance between the universal joint 12 and the platform screw 10, and thus the damper 11 obtains corresponding pressure or tension, so that the damping force of the mechanism is adjusted.
Three, undamped motion mode
1) When the damper 11 is a compression spring, the worm gear transmission rod 20 is twisted to drive the worm gear 6 to rotate, so that the worm 14 contacts the limit pin 18 with the base 9. Therefore, the worm 14 of the platform screw 10 and the universal joint 12 is separated from the elastic connection range formed by the damper 11, so that the rotary spherical core 2 can realize three-degree-of-freedom motion in an undamped state.
2) When the damper 11 is a tension spring, the worm wheel 6 is driven to rotate by twisting the worm wheel transmission rod 20, so that the worm 14 jacks up the universal coupling 12 to the central point of the rotating spherical core 2, and at the moment, the platform screw 10 and the universal coupling 12 cannot change in distance due to any movement of the rotating spherical core 2, so that the rotating spherical core 2 can realize three-degree-of-freedom movement in a non-damping state.
Fourthly, deflection of 90-degree specific position is realized
On the premise that the positioning rod 14 can be adjusted up and down, further, a first U-shaped groove 21 capable of accommodating the ball handle is arranged on one side of the upper end of the shell 4, and a second U-shaped groove 22 capable of allowing the universal coupling 12 or the positioning rod 14 to pass through is arranged on one side of the large round hole of the rotary ball core 2. Since the upper end of the core clamp block 3 in fig. 1 and 2 of this embodiment is flush with the housing 4, a U-shaped groove (not shown) corresponding to the position of the first U-shaped groove 21 is also required to be provided in the core clamp block 3, and if the core clamp block 3 is provided only in the lower portion of the core 2, no additional U-shaped groove is required. The structure is ingenious in that the deflection angle of the rotary ball core 2 at a specific position can reach a limit value of 90 degrees, and the use methods of the structure comprise two methods:
in the first scheme, when the damper 11 adopts a tension spring, the worm wheel transmission rod 20 is twisted to drive the worm wheel 6 to rotate, so that the worm jacks up the universal coupling 12 to the central point of the rotating ball core 2, then the rotating ball core 2 is rotated to enable the second U-shaped groove 22 on the large round hole to correspond to the first U-shaped groove 21 on the shell 4, at the moment, the ball handle is pulled to be rotated into the first U-shaped groove 21 on the shell 4, the edge of the rotating ball core 2 can be avoided through the second U-shaped groove 22 of the rotating ball core 2 when contacting the worm 10 or the universal coupling 12, and therefore the butt joint platform 1 can deflect 90 degrees relative to the worm.
In the second scheme, when the damper 11 adopts a pressure spring, the worm gear transmission rod 20 is twisted to drive the worm gear 6 to rotate, so that the limit nail 18 at the lower end of the worm 14 is in contact with the base 9, and then the ball core 2 is rotated to enable the second U-shaped groove 22 on the large round hole to correspond to the first U-shaped groove 21 on the shell 4; at the moment, the ball handle is turned into the first U-shaped groove 21 on the shell 4, and the edge of the rotary ball core 2 can be avoided through the second U-shaped groove 22 of the rotary ball core 2 when contacting the worm 10 or the universal coupling 12, so that the butt joint platform 1 can generate 90-degree deflection relative to the worm.
The ball joint mechanism that this embodiment provided is equivalent to under the swing joint prerequisite of casing 4 and rotation ball core 2, recycles platform screw rod 10, attenuator 11, universal joint 12 and locating lever 14 and has constructed a set of swing joint system in addition, has both strengthened the joint strength between casing 4 and the rotation ball core 2 like this, can ensure the steady controllable when rotating ball core 2 and moving again. On the basis, the embodiment also provides a plurality of further technical schemes, so that the motion state of the rotary spherical core 2 can be in any one of three motion states of three degrees of freedom, two degrees of freedom and one degree of freedom according to requirements, and the rotary spherical core 2 can deflect to a limit value of 90 degrees at a specific position, thereby enabling the application range of the spherical joint mechanism to be wider. The ball joint mechanism provided by the embodiment can be applied to a shooting and shooting pan-tilt, an astronomical telescope and other various mechanisms which need to carry out two-degree-of-freedom and three-degree-of-freedom and carry out related motion under adjustable damping.
The above embodiments are preferred implementations of the present invention, and the present invention can be implemented in other ways without departing from the spirit of the present invention.
Some of the drawings and descriptions of the present invention have been simplified to facilitate the understanding of the improvements over the prior art by those skilled in the art, and some other elements have been omitted from this document for the sake of clarity, and it should be appreciated by those skilled in the art that such omitted elements may also constitute the subject matter of the present invention.
