An automatic positioning laser tracker

Abstract

This utility model relates to the field of laser tracker technology and discloses an automatic positioning laser tracker, including a tripod and a laser tracker body. The bottom of the laser tracker body is mounted on the top of the tripod. The laser tracker body can drive the embedding hole to fit onto the outside of the embedding plate on the tripod. At this time, the positioning block is compressed and the tension spring is stretched. When the positioning block is aligned with the positioning groove, the reaction force of the tension spring causes the positioning block to be inserted into the positioning groove, thereby facilitating the installation and fixing of the laser tracker body. Through the screw, the limiting plate can be rotated 90 degrees counterclockwise downwards to separate the limiting plate from the handle. Pulling the handle downwards causes the support plate to drive the second guide block to guide and compress the first guide block. At this time, the first guide plate drives the baffle to move into the embedding plate, thereby the baffle drives the positioning block to move inwards and separate from the positioning groove, making it convenient for the operator to disassemble the laser tracker body.

Description

Technical Field

[0001] This utility model relates to the field of laser tracker technology, and more specifically to an automatic positioning laser tracker. Background Technology

[0002] Laser trackers integrate automatic target ball locking technology, enabling them to automatically search for and lock onto the target ball after light is cut off. Measurements can be resumed without manual intervention, significantly improving efficiency. Using the iProbe 6D attitude probe or similar devices, combined with machine vision and gravity alignment technology, laser trackers can not only locate the target's three-dimensional coordinates but also accurately acquire its spatial attitude (pitch angle, yaw angle, etc.), achieving six-degree-of-freedom measurement. This function is particularly important in robot calibration and measurement of internal features of complex workpieces.

[0003] However, when installing existing automatic positioning laser trackers with tripods, the tripod is usually connected to the bottom of the laser tracker via bolts. Due to the lack of a convenient mechanism for installing and disassembling the laser tracker, the operator needs to loosen multiple bolts when disassembling the laser tracker, which is cumbersome and inconvenient. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic positioning laser tracker to solve the problem in the background art that, due to the lack of a mechanism for convenient installation and disassembly of the laser tracker, the disassembly of the laser tracker requires the operator to loosen multiple bolts, which is cumbersome and inconvenient.

[0005] This utility model provides the following technical solution: an automatic positioning laser tracker, including a tripod and a laser tracker body. The bottom of the laser tracker body is mounted on the top of the tripod. An embedded plate is fixedly connected to the top of the tripod. The bottom of the embedded plate has a mounting groove. The bottom of the laser tracker body has an embedded hole. The inner wall of the embedded hole has several positioning grooves. The several positioning grooves are arranged in a circular array at equal intervals. It also includes an elastic mechanism, a plugging mechanism, and a pressing mechanism. The elastic mechanism is set in the mounting groove. The plugging mechanism is set in the mounting groove and can slide through the outer wall of the embedded plate. One end of the elastic mechanism is fixedly connected to one end of the plugging mechanism. A first guide is set on the outside of the plugging mechanism.

A second guide is set on the bottom of the pressing mechanism. The first guide and the second guide are in contact. A limiting member is movable on the bottom of the tripod near the pressing mechanism.

[0006] Furthermore, the elastic mechanism includes a limiting plate, a moving rod, and a tension spring. A connecting ring is fixedly connected to the top of the tripod near the inside of the mounting groove. Several moving rods are provided, and the moving rods slide through both sides of the connecting ring. The moving rods are arranged in a circular array at equal intervals. A limiting plate is fixedly connected to one end of the moving rod near the inner wall of the connecting ring. A tension spring is sleeved on the outside of the moving rod. One end of the tension spring is fixedly connected to one side of the limiting plate, and the other end is fixedly connected to the inner side of the connecting ring.

[0007] Furthermore, the insertion mechanism includes baffles and positioning blocks. Several baffles are provided, and one side of each baffle is fixedly connected to one end of the elastic mechanism. A positioning block is fixedly connected to one side of each baffle. A movable groove is provided on the outer wall of the embedded plate near the outer side of each positioning block.

[0008] Furthermore, the first guide member includes a first guide plate, which is provided in several groups, with two first guide plates in each group fixedly connected to the two sides of the baffle on one side respectively.

[0009] Furthermore, the extrusion mechanism includes a pull rod, a support plate, and a handle. The tripod has an operating groove at its bottom. The pull rod slides through the top of the tripod and extends into the mounting groove. The top of the pull rod is fixedly connected to a support plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model allows the laser tracker body to be driven by the embedded hole to fit onto the outer side of the embedded plate on the tripod. At this time, the positioning block is compressed and the tension spring is stretched. When the positioning block is aligned with the positioning groove, the reaction force of the tension spring causes the positioning block to be inserted into the positioning groove, thus facilitating the installation and fixing of the laser tracker body. At this time, the limiting plate is located at the bottom of the handle. Through the screw, the limiting plate can be rotated 90 degrees counterclockwise downwards to separate the limiting plate from the handle. Pulling the handle down causes the support plate to drive the second guide block to guide and compress the first guide block. At this time, the first guide plate drives the baffle to move into the embedded plate, thereby the baffle drives the positioning block to move inwards and separate from the positioning groove. At this time, the limiting plate is reset so that it is located at the top of the handle, thereby restricting the handle and facilitating the disassembly of the laser tracker body by the operator.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Appendix Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.

[0023] See attached document Figures 1-6 An automatic positioning laser tracker includes a tripod 1 and a laser tracker body 2. The bottom of the laser tracker body 2 is mounted on the top of the tripod 1. An embedded plate 3 is fixedly connected to the top of the tripod 1. The bottom of the embedded plate 3 has a mounting groove 6. The bottom of the laser tracker body 2 has an embedding hole 4. The inner wall of the embedding hole 4 has several positioning grooves 5, which are arranged in a circular array at equal intervals. The system also includes an elastic mechanism, a plugging mechanism, and a pressing mechanism. The elastic mechanism is located in the mounting groove 6, and the plugging mechanism is located in the mounting groove 6. The plugging mechanism slidably penetrates the outer wall of the embedded plate 3. One end of the elastic mechanism is fixedly connected to one end of the plugging mechanism. A first guide is provided on the outside of the plugging mechanism, which is located within the several positioning grooves 5. The pressing mechanism movably penetrates the top of the tripod 1 and is located in the mounting groove 6. A second guide is provided at the bottom of the pressing mechanism. The second guide is in contact with the tripod 1, and a limiting member is movable near the bottom of the extrusion mechanism. When the laser tracker body 2 moves the insertion hole 4 onto the outside of the insertion plate 3 on the tripod 1, the insertion mechanism is compressed. With the help of the elastic mechanism, the insertion mechanism moves into the insertion plate 3. When the insertion mechanism is aligned with the positioning groove 5, the force of the elastic mechanism causes the insertion mechanism to be inserted into the positioning groove 5, thus facilitating the installation and fixing of the laser tracker body 2. At this time, the limiting member is located at the bottom of the extrusion mechanism, which facilitates the support of the extrusion mechanism. When the limiting member rotates counterclockwise by 90 degrees, the limiting member releases the restriction on the extrusion mechanism and pulls the extrusion mechanism down, causing the extrusion mechanism to drive the second guide to compress the first guide, causing the first guide to drive the insertion mechanism to separate from the positioning groove 5, thus facilitating the disassembly of the laser tracker body 2.

[0024] Specifically, the elastic mechanism includes a limiting plate 8, a moving rod 9, and a tension spring 10. A connecting ring 7 is fixedly connected to the top of the tripod 1 near the inside of the mounting groove 6. Several moving rods 9 are provided, and these moving rods 9 slide through both sides of the connecting ring 7. The moving rods 9 are arranged in a circular array at equal intervals. The limiting plate 8 is fixedly connected to one end of the moving rod 9 near the inner wall of the connecting ring 7. A tension spring 10 is sleeved on the outside of the moving rod 9. One end of the tension spring 10 is fixedly connected to one side of the limiting plate 8, and the other end is fixedly connected to the inside of the connecting ring 7. Pulling the laser tracker body 2 causes the laser tracker body 2 to move the embedding hole 4 onto the outside of the embedding plate 3 on the tripod 1. At this time, the insertion mechanism is compressed, and the insertion mechanism drives the moving rod 9 to move, thereby causing the tension spring 10 to stretch. When the insertion mechanism is aligned with the positioning groove 5, due to the reaction force of the tension spring 10, the insertion mechanism is inserted into the positioning groove 5, thereby facilitating the installation and fixation of the laser tracker body 2.

[0025] Specifically, the insertion mechanism includes baffles 11 and positioning blocks 13. Several baffles 11 are provided, and one side of each baffle 11 is fixedly connected to one end of the elastic mechanism. A positioning block 13 is fixedly connected to one side of each baffle 11. A moving groove 14 is provided on the outer wall of the embedded plate 3 near the outer side of each positioning block 13. Due to the restriction of the positioning block 13 by the baffles 11, the positioning block 13 can only move to the outer side of the embedded plate 3 at one end.

[0026] Specifically, the first guide member includes a first guide plate 12, and the first guide plate 12 is provided in several groups. Two of the first guide plates 12 in each group are fixedly connected to the two sides of the baffle 11 on one side respectively. Due to the function of the first guide plate 12, when the second guide member squeezes the first guide plate 12, the first guide plate 12 can drive the baffle 11 to move into the mounting groove 6.

[0027] Specifically, the extrusion mechanism includes a pull rod 16, a support plate 17, and a handle 20. The tripod 1 has an operating groove 15 at its bottom. The pull rod 16 slides through the top of the tripod 1 and extends into the mounting groove 6. The top of the pull rod 16 is fixedly connected to the support plate 17. The outer wall of the support plate 17 fits against the inner wall of the mounting groove 6. The bottom of the pull rod 16 is fixedly connected to the handle 20. Pulling the handle 20 downward causes the handle 20 to move the pull rod 16, thereby moving the support plate 17. This facilitates the support plate 17 to move the second guide member downward, making it easier for the second guide member to contact the first guide plate 12.

[0028] Specifically, the second guide component includes a connecting plate 18 and a second guide block 19. Several connecting plates 18 are provided, and the top ends of several connecting plates 18 are fixedly connected to the bottom end of the support plate 17. The several connecting plates 18 are arranged in a circular array at equal intervals. The second guide blocks 19 are fixedly connected to both sides of the bottom end of the connecting plates 18. When the support plate 17 moves downward and drives the second guide block 19 to guide and squeeze the first guide block, the first guide plate 12 drives the baffle 11 to move into the embedded plate 3, thereby the baffle 11 drives the positioning block 13 to move inward and separate from the positioning groove 5.

[0029] Specifically, the limiting components include a concave seat 21, a screw 22, and a limiting plate 23. One side of the concave seat 21 is fixedly connected to the inner wall of the operating groove 15. The screw 22 is fixedly connected inside the concave seat 21, and the limiting plate 23 is threadedly connected to the outer wall of the screw 22. In the initial state, the top of the limiting plate 23 contacts the bottom of the handle 20, thereby supporting the handle 20 and preventing the support plate 17 from moving downward under the action of gravity.

[0030] The working principle and usage process of this utility model are as follows: When in use, pull the laser tracker body 2, causing it to move the embedding hole 4 onto the outer side of the embedding plate 3 on the tripod 1. At this time, the positioning block 13 is compressed and moves into the moving groove 14. This causes the positioning block 13 to move the baffle 11, which in turn moves the moving rod 9. This movement stretches the tension spring 10. When the positioning block 13 aligns with the positioning groove 5, the reaction force of the tension spring 10 causes the positioning block 13 to insert into the positioning groove 5, thus facilitating the installation and fixation of the laser tracker body 2. At this time, the limiting plate 23 is located at the bottom of the handle 20. Additionally, rotating counterclockwise ninety degrees... Rotate the limiting plate 23 downwards, causing it to move on the screw 22. At this time, the limiting plate 23 separates from the handle 20. Pull the handle 20 downwards, causing it to move the pull rod 16. The pull rod 16 then moves the support plate 17, which in turn moves the second guide block 19 to guide and press the first guide block. This causes the first guide plate 12 to move the baffle 11 into the embedded plate 3. The baffle 11 then moves the positioning block 13 inwards and separates it from the positioning groove 5. At this time, reset the limiting plate 23 so that it is located at the top of the handle 20, thereby restricting the handle 20 and facilitating the disassembly of the laser tracker body 2 by the operator.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
