Referring to fig. 1, the rotation member 5 is provided in the form of a ball-shaped abacus bead, that is, the rotation member 5 is formed by removing upper and lower portions of a ball and vertically providing a screw hole 51, and the overall shape is similar to the shape of an abacus bead. The second sleeve 4 is provided with a containing hole 41, the rotating member 5 is rotatably connected in the containing hole 41, and the inner side wall of the containing hole 41 is matched with the outer side wall of the rotating member 5 so that the rotating member 5 cannot move along the axial direction of the containing hole 41.

The adjusting gap 23 is used for allowing the bolt 22 to freely move in the adjusting hole 21 along the direction perpendicular to the axis of the bolt 22 when the first member 1 and the second member 2 are connected, so that the transverse deviation between the adjusting hole 21 on the second member 2 and the threaded hole 51 on the rotating piece 5 is adjusted, and the position deviation in the three-axis direction is adjusted under a rectangular 90-degree coordinate system.

The working principle is as follows:

when the first member 1 and the second member 2 are connected, the second sleeve 4 and the first sleeve 3 are connected through the screw transmission structure 6 and located between the two members, the rotating piece 5 is rotated to rotate the threaded hole 51 to be aligned with the adjusting hole 21, then the bolt 22 is threaded into the threaded hole 51 through the adjusting hole 21, and when the bolt 22 is continuously threaded into the threaded hole 51, the second sleeve 4 is moved away from the first sleeve 3 because the distance between the first member 1 and the second member 2 is not changed. In the process that the second sleeve 4 is far away from the first sleeve 3, due to the guiding effect of the spiral transmission structure 6, the second sleeve 4 drives the rotating piece 5 to rotate around the central axis of the first sleeve 3 together until the rotating piece 5 collides with the second component 2. Thus, only tightening of the bolt 22 is required to cause automatic elongation between the first sleeve 3 and the second sleeve 4, thereby accommodating the distance between the first member 1 and the second member 2. After the bolt 22 is screwed, the rotating member 5 and the second sleeve 4 do not rotate around the central axis of the first sleeve 3 because the rotating member 5 abuts against the second member 2, so that the first sleeve 3 and the second sleeve 4 do not rotate, and the distance between the first sleeve 3 and the second sleeve 4 does not change.

Example 2:

referring to fig. 2 and 3, the present embodiment is different from embodiment 1 in that: this regulator is still including fixed subassembly, and first sleeve 3 is fixed with first component 1 through fixed subassembly, and fixed subassembly is including connecting cylinder 8, connects

cylinder

8 and 3 fixed connection of first sleeve, and connects

cylinder

8 and 1 spiro union, joint or the riveting of first component.

Referring to fig. 3, the connecting cylinder 8 is clamped with the first member 1. The connecting column body 8 is provided with a clamping head, the first component 1 is provided with a clamping hole, and the clamping head is inserted into the clamping hole to realize clamping. Referring to fig. 2, the connection column 8 is screwed with the first member 1, and the specific screwing manner is as follows: the first component 1 is provided with a connecting hole 11, the fixing assembly further comprises a fixing nut 9, the connecting column body 8 comprises a rotation stopping section 81 inserted into the connecting hole 11 and a thread section 82 matched with the fixing nut 9, the rotation stopping section 81 is located between the thread section 82 and the first sleeve 3, the rotation stopping section 81 is matched with the connecting hole 11, the rotation stopping section 81 cannot rotate in the connecting hole 11, and the first component 1 is locked through the fixing nut 9 after the rotation stopping section 81 is inserted into the connecting hole 11. The connection hole 11 may be a waist-shaped hole or a polygonal hole, and the rotation stopping section 81 is configured in a shape adapted to the connection hole 11. In this embodiment, the connection hole 11 is a square hole, and the rotation stopping section 81 is also set to be square. The rotation stop section 81 is arranged such that the connection cylinder 8 does not rotate relative to the connection hole 11 when the fixing nut 9 is tightened.

Example 3:

referring to fig. 5, the ball type automatic tolerance adjusting apparatus according to the present embodiment includes at least two ball type automatic tolerance adjusters according to embodiment 1 or embodiment 2, and the adjusters fix the first member 1 and the second member 2 at the same time.

Referring to fig. 5, in particular, when only one adjuster is used, the adjuster cannot lock the angle between the first member 1 and the second member 2 because the rotation member 5 and the second sleeve 4 can rotate relatively. When an external force is applied between the two components to change the angle between the two components, the rotation member 5 and the second sleeve 4 in the adjuster rotate relatively. When only two adjusters are used, the adjusters substantially lock the first member 1 and the second member 2, and the first member 1 and the second member 2 are subjected to an external force and are only allowed to rotate relative to a line connecting the two adjusters. And when adopting three regulators, and three regulators are not on same straight line, relative rotation between first component 1 and second component 2 is locked totally, and first component 1 can't rotate relative to second component 2, connects more reliably steadily.

The direction of rotation of the screw drive 6 of at least one actuator is opposite to the direction of rotation of the screw drive 6 of the other actuator. Specifically, since the first transmission part 61 and the second transmission part 62 have a gap therebetween, after the first member 1 and the second member 2 are connected, a slight relative movement between the first member 1 and the second member 2 is possible due to the gap, which is not favorable for precise positioning between the first member 1 and the second member 2. When the screw driving structure 6 of the adjuster has opposite rotation directions, a slight relative movement between the first member 1 and the second member 2 due to a gap between the first driving part 61 and the second driving part 62 can be avoided, thereby improving the mounting accuracy between the first member 1 and the second member 2.

When a plurality of adjusters are adopted, when the turning directions of the two adjusters which are farthest away are set to be opposite to the turning directions of the other adjusters, the influence of the gap of the screw transmission structure 6 is minimum, and the mounting precision is highest. Referring to fig. 5, in the present embodiment, the first member 1 and the second member 2 are connected by four adjusters, the four adjusters are arranged at four corners, the spiral transmission structures 6 of two adjusters on the same diagonal have the same rotation direction, and the spiral transmission structures 6 of two adjusters on different diagonals have opposite rotation directions.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model, and are considered to be within the scope of the utility model.
