A first adjusting gap 12 is formed between the screw of the bolt 36 and the first adjusting hole 11. The first adjusting gap 12 is used for allowing the bolt 36 to freely move in the first adjusting hole 11 in a direction perpendicular to the axis of the bolt 36 when the first member 1 and the second member 2 are connected, so that the transverse deviation between the first adjusting hole 11 on the first member 1 and the threaded hole on the fixing member 31 is adjusted, and the position deviation in the three-axis direction is adjusted under a 90-degree rectangular coordinate system.

The working principle is as follows:

when the first member 1 and the second member 2 are connected, the second sleeve and the first sleeve are connected through the transmission thread 22 and are positioned between the two members, the fixing piece 31 is rotated to be aligned with the first adjusting hole 11 on the first member 1, then the bolt 36 is threaded into the fixing piece 31 through the first adjusting hole 11, and when the bolt 36 is continuously threaded into the fixing piece 31, the second sleeve is moved away from the first sleeve due to the constant distance between the first member 1 and the second member 2. During the process of the second sleeve moving away from the first sleeve, the second sleeve drives the adjusting member 32 and the fixing member 31 to rotate together around the central axis of the first sleeve due to the guiding effect of the transmission thread 22 until the fixing member 31 interferes with the first member 1. It is therefore only necessary to tighten the bolts 36 to enable automatic elongation between the first and second sleeves to accommodate the distance between the first and

second members

1, 2. After the bolt 36 is tightened to the fixing member 31, the fixing member 31 is fixed to the first member 1, so that the fixing member 31 does not rotate, the first sleeve and the second sleeve do not rotate, and the distance between the first sleeve and the second sleeve does not change.

The connecting column 41 is provided with a clamping head, the second component 2 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 body is screwed with the second member 2, specifically in the following manner: the second member 2 is provided with a connecting hole 23, the fixing assembly 4 further comprises a fixing nut 42, the connecting column 41 comprises a rotation stopping section 411 inserted into the connecting hole 23 and a threaded section 412 matched with the fixing nut 42, the rotation stopping section 411 is located between the threaded section 412 and the first cylinder 21, the rotation stopping section 411 is matched with the connecting hole 23, the rotation stopping section 411 cannot rotate in the connecting hole 23, and the second member 2 is locked by the fixing nut 42 after the rotation stopping section 411 is inserted into the connecting hole 23. The connection hole 23 may be a waist-shaped hole or a polygonal hole, and the rotation stopping section 411 is provided in a shape adapted to the connection hole 23. In this embodiment, the connection hole 23 is a square hole, and the rotation stopping section 411 is also square. The rotation stopping section 411 is provided so that the coupling cylinder 41 does not rotate with respect to the coupling hole 23 when the fixing nut 42 is tightened.

Example 3:

referring to fig. 4, the present embodiment is different from embodiment 1 in that: the fixing member 31 is fixed to the first member 1 by a bolt 36, a second adjusting hole 311 is formed in the fixing member 31, and a second adjusting gap 312 is formed between a screw of the bolt 36 and the second adjusting hole 311.

Referring to fig. 4, in particular, the fixing member 31 is integrally formed with an interference portion for interfering with the first member 1. The first member 1 is provided with a through hole, the bolt 36 is a flange bolt 36, and the bolt 36 passes through the second adjusting hole 311 and the through hole respectively and then is screwed by a nut. When screwing, the flange and the abutting part on the flange bolt 36 clamp the first member 1, thereby realizing the connection and fixation of the fixing piece 31 and the first member 1. A second adjusting gap 312 is formed between the screw of the bolt 36 and the second adjusting hole 311. The second adjusting gap 312 is used for allowing the bolt 36 to freely move in the second adjusting hole 311 along a direction perpendicular to the axis of the bolt 36 when the first member 1 and the second member 2 are connected, so as to adjust the transverse deviation between the through hole on the first member 1 and the second adjusting hole 311 on the fixing member 31, and thus, the position deviation in the three-axis direction can be adjusted in a 90-degree rectangular coordinate system.

Example 4:

referring to fig. 7, a biaxial automatic angle adjusting device includes at least two biaxial automatic angle adjusters according to embodiment 1, embodiment 2, or embodiment 3. The adjuster simultaneously fixes the first member 1 and the second member 2.

Referring to fig. 7, 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 fixing member 31 and the second cylinder 33 can rotate relatively. When an external force is applied between the two components to change the angle between the two components, relative rotation occurs between the fixing member 31 and the second cylinder 33 in the adjuster. 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 drive threads 22 of at least one of the adjusters are oppositely threaded to the drive threads 22 of the other adjusters. Specifically, since the transmission screw 22 has a gap, 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 still possible due to the gap of the transmission screw 22, which is not favorable for precise positioning between the first member 1 and the second member 2. When the rotation directions of the transmission threads 22 are different between the adjusters, a slight relative movement between the first member 1 and the second member 2 due to the clearance of the transmission threads 22 can be avoided, thereby improving the mounting accuracy between the first member 1 and the second member 2.

When a plurality of adjusters are used, the rotation direction of the two adjusters which are farthest away is set to be opposite to the rotation direction of the other adjusters, and the influence of the clearance of the transmission thread 22 is minimized, and the mounting accuracy is maximized. Referring to fig. 7, 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 rotation directions of the transmission threads 22 of the two adjusters on the same diagonal are the same, and the rotation directions of the transmission threads 22 of the two adjusters on different diagonals are opposite.

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.
