Abstract
Description
Technical Field
[0001] This utility model belongs to the field of measurement technology, specifically, it relates to an improvement of a horizontal adjustment device for a laser tracker. Background Technology
[0002] Laser trackers can measure the distance to a target point and its horizontal and vertical deflection angles. The basic principle is to place a reflector at the target location. The laser emitted by the laser tracker head strikes the reflector and reflects back to the tracker head. As the target moves, the tracker head adjusts the beam direction to align with the target. Measurement accuracy is the primary consideration when using a laser tracker. Before measurement, the laser tracker should be adjusted according to the site environment to achieve a relatively horizontal state, thus ensuring the vertical height position and improving measurement accuracy.
[0003] Currently, the Leica laser tracker is leveled primarily by using the horizontal adjustment bases connected to the various support legs at the bottom of the tripod. During adjustment, the level is rotated and adjusted according to the reading on the Leica laser tracker's level gauge until the level gauge reading reaches within the threshold.
[0004] The above adjustment methods are time-consuming and difficult to master for those without special training or experience. Furthermore, once the tripod is set up, the three support legs occupy a significant amount of space, making it difficult and inconvenient to adjust two leveling bases simultaneously.
[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content
[0006] This invention addresses the aforementioned technical problems in the leveling of laser trackers in the prior art by proposing a laser tracker leveling device that enables quick and convenient leveling of the laser tracker.
[0007] To achieve the above-mentioned utility model / design objectives, the present utility model adopts the following technical solution:
[0008] A horizontal adjustment device for a laser tracker, the horizontal adjustment device being connected between a support frame for supporting the laser tracker and a connecting base for assembling the laser tracker, comprising:
[0009] The first component, the second component, and the third component are connected sequentially from bottom to top;
[0010] The first rotating component is rotatable.
[0011] The first spiral fitting component is connected to the second component and cooperates with the first screw component. When the first screw component rotates, it can move up and down, causing the second component and the third component to swing up and down relative to the horizontal plane with the first direction as the axis.
[0012] The second knob is rotatable;
[0013] The second threaded assembly engages with the second screwing part and connects to the second component. It is movable relative to the second component in the height direction and can move up and down relative to the second component when the second screwing part rotates, causing the third component to swing up and down relative to the horizontal plane with the second direction as the axis. The second direction is perpendicular to the first direction.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are:
[0015] The horizontal adjustment device for the laser tracker in this invention includes a first and a second rotary component. When the horizontal position of the laser tracker needs to be adjusted, the first rotary component can be turned to rotate the second component relative to the first component, causing it to swing up and down relative to the horizontal plane along the first direction as its axis. At the same time, the second rotary component can be turned to rotate the third component relative to the second component, allowing the third component to swing up and down relative to the horizontal plane along the second direction as its axis of rotation. This achieves fine-tuning of the horizontal position of the laser tracker from two mutually perpendicular directions, ensuring that the tracker can be quickly adjusted to a horizontal position. The horizontal position adjustment of the laser tracker can be achieved simply by turning the rotary components, making the adjustment operation more convenient and faster.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0032] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0033] A horizontal adjustment device for a laser tracker is provided, wherein the horizontal adjustment device is connected between a support frame for supporting the laser tracker and a connecting base for assembling the laser tracker.
[0034] The support frame is a triangular support frame, which is connected to the leveling device. The connection method can be conventional connection methods such as threaded connection or snap fastener.
[0035] The connector is installed on the leveling device and can be threadedly connected to the leveling device.
[0036] The laser tracker is mounted on the connector.
[0037] When the horizontal adjustment device performs a horizontal adjustment action, it can transmit the signal to the connecting seat, which in turn drives the laser tracker to change its position for adjustment.
[0038] The leveling device specifically includes:
[0039] The first component 100, the second component 200, and the third component 300 are connected sequentially from bottom to top.
[0040] The first component 100 is a base, the second component 200 is an adjustment seat, and the third component 300 is a mounting seat. The third component 300 is connected to the connecting seat.
[0041] The first component 100, the second component 200, and the third component 300 are arranged sequentially from top to bottom and connected to each other.
[0042] Specifically, the second component 200 is rotatably connected to the first component 100 about the first direction as the axis, and the third component 300 is rotatably connected to the second component 200 about the second direction as the axis.
[0043] The first rotating component 410 is rotatable;
[0044] The first spiral fitting 420 is connected to the second component 200 and cooperates with the first screw component 410. When the first screw component rotates, it can move up and down, causing the second component 200 and the third component 300 to swing up and down relative to the horizontal plane with the first direction as the axis.
[0045] The first direction is along the Y-axis.
[0046] The first rotary element 410 and the first spiral engagement element 420 are threaded together. When the first rotary element 410 rotates, it will drive the first spiral engagement element 420 to move up and down. The first spiral engagement element 420 is connected to the second component 200, and synchronously drives the second component 200 and the third component 300 connected to the second component 200 to rotate relative to the first component 100, so that it swings up and down relative to the horizontal plane along the Y-axis to achieve adjustment of the horizontal position of the laser tracker along the Y-axis.
[0047] During adjustment, simply rotating the first knob 410 will automatically drive the second component 200 and the third component 300 and the laser tracker above them to swing along the Y-axis to adjust their horizontal position. The adjustment operation is convenient and quick.
[0048] The second rotating component 510 is rotatable;
[0049] The second threaded assembly 520 engages with the second screwing member and is connected to the second component 200. It is movable relative to the second component 200 in the height direction and can move up and down relative to the second component 200 when the second screwing member rotates, thereby causing the third component 300 to swing up and down relative to the horizontal plane with the second direction as the axis, wherein the second direction is perpendicular to the first direction.
[0050] The second direction is the direction of the X-axis.
[0051] Since the second threaded engagement assembly 520 is connected to the second component 200, turning the second knob 510 will cause the second threaded engagement assembly 520 to move up and down. Since the second component 200 is rotatably connected to the first component 100 along the first direction, it cannot move up and down. Therefore, the second threaded engagement assembly is set to be movable in the height direction with the second component 200 to ensure that when the second knob is turned, the second threaded engagement assembly 520 can move up and down normally, the second component 200 does not move, and the third component 300 can rotate relative to the second component 200 along the X-axis direction.
[0052] During adjustment, rotating the second knob causes the second threaded engagement component 520 to move up and down. When the second threaded engagement component 520 moves up and down, it causes the third component 300 to swing up and down relative to the horizontal plane along the X-axis, thereby adjusting the horizontal position of the laser tracker connected to the third component 300 along the X-axis. The adjustment operation is convenient.
[0053] The laser tracker horizontal adjustment device in this embodiment is provided with a first rotary member 410 and a second rotary member 510. When it is necessary to adjust the horizontal position of the laser tracker, the first rotary member 410 can be turned to drive the second component 200 to rotate relative to the first component 100, so that it swings up and down relative to the horizontal plane along the first direction as the axis. At the same time, the second rotary member 510 can be turned to drive the third component 300 to rotate relative to the second component 200, so that the third component 300 can swing up and down relative to the horizontal plane with the second direction as the axis of rotation. This realizes the swing fine adjustment of the horizontal position of the laser tracker from two mutually perpendicular directions, ensuring that the tracker can be quickly adjusted to a horizontal position. The horizontal position adjustment of the laser tracker can be achieved simply by turning the rotary members, making the adjustment operation more convenient and faster.
[0054] During adjustment, the value displayed on the level gauge on the laser tracker can be used to determine whether the adjustment is in place.
[0055] Furthermore, the laser tracker horizontal adjustment device in this embodiment is located between the support frame and the connecting seat, and directly adjusts the horizontal position of the laser tracker assembled on the connecting seat. Compared with the existing technology that uses the support adjustment base at the bottom of the support frame for adjustment, it does not need to consider the influence of ground flatness, and the adjustment is more precise.
[0056] In some embodiments of this application, the second component 200 includes a component body portion 210;
[0057] And a first swing arm 220 extending from the component body 210, wherein a first mounting groove 221 for inserting the first helical fitting 420 is formed in the first swing arm 220;
[0058] The first connector 230 is transversely inserted through the first swing arm 220 and the first helical fitting 420 to connect the first swing arm 220 and the first helical fitting 420.

The first connecting pin passes through the first through hole and the first mounting groove 221 to connect the second component 200 and the first helical fitting 420. Thus, when the first helical fitting 420 moves up and down, it can drive the second component 200 to swing.
[0061] In some embodiments of this application, the second threaded assembly 520 includes a second helical fitting 521 and a pressing member 522 fixed on the second helical fitting 521.

[0064] When the second spiral fitting 521 moves up and down, it will drive the pressing part 522 to move up and down. The pressing part 522 presses against the edge of the third component 300, which will cause the third component 300 to swing along the second direction.
[0065] In some embodiments of this application, the second component 200 includes a second swing arm 240 extending from the component body portion 210. The second swing arm 240 is provided with a second mounting groove 241 through which the second helical fitting 521 is inserted.

[0068] A second through hole is provided on the second swing arm 240, and the second through hole is connected to the second mounting groove 241.
[0069] The second connector 250 is a second connecting pin, which is inserted into the second through hole and the movable elongated hole of the second spiral fitting 521 located in the second mounting groove 241, so as to connect the second component 200 with the second spiral fitting 521.
[0070] Meanwhile, the movable elongated hole in the second spiral fitting 521 can ensure that the second spiral fitting 521 will not drive the second component 200 to move up and down together when it moves up and down.

[0086] The second rotating part 290 is a second rotating shaft. A second clearance groove 280 is provided on the second component 200 at a position corresponding to the position of the assembly 330. The second rotating shaft is inserted into the side wall of the second clearance groove 280.
[0087] The assembly 330 is an assembly block, which is fixed at the bottom of the third component 300. The second insertion part 331 is a second insertion hole, which is used to insert the second rotating shaft.
[0088] By cooperating with the second rotating shaft and the second insert 331, the rotation of the third component 300 can be guided, causing it to rotate along the second rotating shaft with the axial direction as the second direction, thus ensuring the accuracy of the adjustment.
