[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0043] like Figure 1The figure shows a schematic structural diagram of an embodiment of a laser adjustment frame assembly of the present invention. The laser adjustment frame assembly of this embodiment includes a laser joint flange 1, which includes a shaft tube 1a and a flange 1b provided on the shaft tube 1a. The laser adjustment frame assembly of this embodiment also includes a plane position adjustment seat 2 and a swing adjustment seat 3. Specifically, when the plane position adjustment seat 2 is located inside the swing adjustment seat 3, the flange 1b is located inside the plane position adjustment seat 2 and swings synchronously with the plane position adjustment seat 2; when the swing adjustment seat 3 is located inside the plane position adjustment seat 2, the flange 1b is located inside the swing adjustment seat 3 and moves synchronously with the swing adjustment seat 3. The plane position adjustment seat 2 of this embodiment is located inside the swing adjustment seat 3. The plane position adjustment seat 2 of this embodiment is provided with a plane position adjustment mechanism for adjusting the position of the laser joint flange 1 on the plane; the swing adjustment seat 3 is provided with a swing angle adjustment mechanism for driving the laser joint flange 1 to swing and thereby adjusting its inclination angle relative to the plane.

[0044] Furthermore, the plane position adjustment mechanism of this embodiment includes two linear position adjustment mechanisms for respectively adjusting the position of the laser joint flange 1 in two directions perpendicular to each other. Specifically, each linear position adjustment mechanism includes a linear adjustment screw 5 whose axis is parallel to the plane and a linear return spring 6 for driving the flange 1b or the swing adjustment seat 3 to always maintain contact and cooperation with the linear adjustment screw 5, and the linear adjustment screw 5 is threadedly engaged with the plane position adjustment seat 2. A positioning hole 7 is provided on the side wall of the flange 1b or the swing adjustment seat 3 of this embodiment, and a positioning section 5a is provided on the head of the linear adjustment screw 5 that extends into the positioning hole 7, so as to realize the positioning cooperation between the linear adjustment screw 5 and the flange 1b. Preferably, the linear return spring 6 and the linear adjustment screw 5 belonging to the same linear position adjustment mechanism of this embodiment are coaxially arranged.

[0045] Furthermore, in this embodiment, the linear return spring 6 and the corresponding linear adjustment screw 5 are respectively located on both sides of the same radial direction of the flange 1b or the swing adjustment seat 3, and the linear return spring 6 applies pressure to the flange 1b or the swing adjustment seat 3. The plane position adjustment seat 2 is provided with a spring plug 8 corresponding to the linear return spring 6. Of course, the linear return spring 6 and the corresponding linear adjustment screw 5 can also be arranged to be located on the same side of the flange 1b or the swing adjustment seat 3. For example, the linear return spring 6 can be sleeved on the corresponding linear adjustment screw 5. In this case, the linear return spring 6 applies a tensile force to the flange 1b or the swing adjustment seat 3, and the screw hole provided on the plane position adjustment seat 2 that threadably cooperates with the linear adjustment screw 5 is provided on the spring plug 8, which can also achieve the same technical purpose.

[0046] Furthermore, the swing angle adjustment mechanism of this embodiment includes a swing adjustment block 9, a swing return spring 10 and a swing drive mechanism. The swing adjustment block 9 is provided with a swing adjustment surface. The swing return spring 10 drives the flange 1b or the plane position adjustment seat 2 to always be in contact with the swing adjustment surface. The swing drive mechanism is used to drive the swing adjustment block 9 and the corresponding flange 1b or the plane position adjustment seat 2 to move relative to each other, and to make the corresponding flange 1b or the plane position adjustment seat 2 swing under the action of the swing adjustment surface. The swing adjustment surface can be implemented in a variety of ways, such as two inclined surfaces or curved surfaces set in two directions perpendicular to each other on the swing adjustment block 9. The inclined surfaces or curved surfaces can drive the corresponding flange 1b or the plane position adjustment seat 2 to swing. Of course, the inclined surfaces or curved surfaces can also be set at both ends of the swing adjustment block 9 in two directions perpendicular to each other, which can also achieve the technical purpose of driving the corresponding flange 1b or the plane position adjustment seat 2 to swing. The swing adjustment block 9 of this embodiment is provided with a circular groove. The inner diameter of the sidewall of the circular groove gradually decreases from the groove opening to the bottom of the groove. The sidewall of the circular groove smoothly transitions to the bottom of the groove, forming the swing adjustment surface. This surface can achieve the technical purpose of driving the corresponding flange 1b or the plane position adjustment seat 2 to swing. Specifically, the swing angle adjustment mechanism of this embodiment includes two swing block position adjustment mechanisms for adjusting the position of the swing adjustment block 9 in two mutually perpendicular directions. The swing block position adjustment mechanism of this embodiment includes a threaded hole 11 provided on the side of the swing adjustment block 9 and a swing adjustment screw 12 threadedly engaged with the threaded hole 11. The swing adjustment screw 12 is axially fixed relative to the swing adjustment seat 3. Specifically, the swing adjustment seat 3 of this embodiment is provided with a through hole 4 for the swing adjustment screw 12 to pass through. Both ends of the through hole 4 are axially restrained by the swing adjustment screw 12. The swing adjustment screw 12 of this embodiment is restrained by its screw head and one end of the through hole 4. A retaining ring 21 is mounted on the swing adjustment screw 12 and restrained by the other end of the through hole 4. This prevents the swing adjustment screw 12 from moving axially relative to the swing adjustment seat 3. Of course, a retaining spring 21 located at both ends of the through hole 4 may also be provided on the swing adjustment screw 12 , so that the two retaining springs 21 can be used to achieve axial limitation between the swing adjustment screw 12 and the swing adjustment seat 3 .

[0047] Furthermore, in this embodiment, the swing adjustment screw 12 and the swing return spring 10 are respectively located at the two ends of the flange 1b or the plane position adjustment seat 2. In this case, the swing return spring 10 applies pressure to the flange 1b or the plane position adjustment seat 2, thereby ensuring that the flange 1b or the plane position adjustment seat 2 is always in contact with the swing adjustment surface. Of course, the swing adjustment block 9 and the swing return spring 10 can also be arranged to be located at the same end of the flange 1b or the plane position adjustment seat 2, and the swing return spring 10 applies a tensile force to the flange 1b or the plane position adjustment seat 2, which can also achieve the technical purpose of ensuring that the flange 1b or the plane position adjustment seat 2 is always in contact with the swing adjustment surface.

[0048] Furthermore, the laser joint flange 1 swings about a set center point on its axis under the action of the swing adjustment surface. By providing a swing adjustment surface on the swing adjustment block and allowing the laser joint flange to swing about a set center point on its axis under the action of the swing adjustment surface, that is, when the swing angle of the laser joint flange relative to the plane is adjusted, the position of the center point remains unchanged, overcoming the problem in the prior art that the position of the laser joint flange in a direction perpendicular to the plane will change when the swing angle is adjusted.

[0049] Furthermore, the plane position adjustment base 2 of this embodiment includes a plane position adjustment base 2a and a plane position adjustment cover 2b mounted on the plane position adjustment base 2a; the swing adjustment base 3 includes a swing adjustment base 3a and a swing adjustment cover 3b mounted on the swing adjustment base 3a. The plane position adjustment cover 2b and the swing adjustment cover 3b of this embodiment are respectively provided with a connecting hole I 14 and a connecting hole II 15 for the shaft tube 1a to pass through. The plane position adjustment base 2a and the swing adjustment base 3a are respectively provided with a light guide channel I 16 and a light guide channel II 17. A light shielding tube 18 is disposed within light guide channel I 16 or II 17. When the plane position adjustment base 2 is positioned inside the swing adjustment base 3, the light shielding tube 18 is disposed within light guide channel II 17. When the swing adjustment base 3 is positioned inside the plane position adjustment base 2, the light shielding tube 18 is disposed within light guide channel I 16. In this embodiment, the light shielding tube 18 is disposed within light guide channel II 17.

[0050] Furthermore, the laser adjustment frame assembly of this embodiment also includes a laser adjustment frame base 19, which is positioned corresponding to light guide channel I 16 or light guide channel II 17. A laser adjustment screw 20 is positioned between the laser adjustment frame base 19 and the corresponding light guide channel I 16 or light guide channel II 17. The laser adjustment screw 20 has two internal threads at each end, each with opposite rotation directions. The two internal threads respectively engage with the laser adjustment frame base 19 and the corresponding light guide channel I 16 or light guide channel II 17. In this embodiment, the two internal threads respectively engage with the laser adjustment frame base 19 and light guide channel II 17. By positioning the laser adjustment screw between the light guide channel and the laser adjustment base, the laser adjustment screw can be rotated. Since the two internal threads of the laser adjustment screw have opposite rotation directions, the rotation of the laser adjustment screw can drive the laser adjustment frame base and light guide channel I or the laser adjustment frame base and light guide channel II to move toward or away from each other, thereby adjusting the position of the laser joint flange in a direction perpendicular to the plane without causing any changes in the adjustment of other positional parameters of the laser joint flange.

[0051] The plane position adjustment seat 2 of this embodiment is located inside the swing adjustment seat 3. The linear return spring 6 of this embodiment drives the flange 1b to always maintain contact and cooperation with the linear adjustment screw 5. The positioning hole 7 is set on the side wall of the flange 1b. The linear return spring 6 and the corresponding linear adjustment screw 5 are respectively located on both sides of the same radial direction of the flange 1b, and the linear return spring 6 is located between the plane position adjustment seat 2 and the flange 1b. The swing adjustment block 9 of this embodiment maintains contact and cooperation with the plane position adjustment seat 2, and the swing adjustment block 9 is located below the plane position adjustment seat 2. The bottom surface of the plane position adjustment seat 2 maintains contact and cooperation with the swing adjustment surface. The elastic force exerted by the swing return spring 10 of this embodiment acts directly on the plane position adjustment seat 2, and the swing return spring 10 is set between the plane position adjustment cover 21 and the swing adjustment cover 13.

[0052] The laser adjustment frame assembly of this embodiment is equipped with a plane position adjustment seat and a swing adjustment seat, and respectively arranges a plane position adjustment mechanism and a swing angle adjustment mechanism on the plane position adjustment seat and the swing adjustment seat. That is, the plane position adjustment mechanism and the swing angle adjustment mechanism can independently adjust the position of the laser joint flange on the plane and the swing angle relative to the plane, thereby avoiding mutual influence between the laser joint flanges when adjusting the plane position and adjusting the swing angle, and no associated changes will be generated. It has the advantages of simple operation and accurate adjustment.

[0053] Note: The “plane” mentioned herein is a plane perpendicular to the axis of the laser adjustment frame base 19 .
