Description
Technical Field
[0001] This utility model relates to the field of laser positioning technology, and in particular to a high-precision laser positioning device. Background Technology
[0002] A high-precision laser positioning device is a device that uses laser technology for precise measurement and positioning. It determines the position, distance, or angle of a target object by emitting a laser beam and using the reflection or scattering signals of the laser. It is widely used in industrial, scientific research, and engineering measurement fields. Compared with traditional mechanical measurement methods, laser positioning devices have the characteristics of high precision, high speed, non-contact operation, and strong adaptability.
[0003] Currently, when using laser positioning devices, if the position between the target and the laser emitter is not suitable, the laser signal will have difficulty reaching the target, resulting in inaccurate positioning data. Furthermore, the measurement angle range is small during positioning. When some positioning requires large angle changes, the small angle adjustment range makes it difficult to achieve a suitable positioning angle, thus affecting the positioning effect. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a high-precision laser positioning device, including a main body, a support leg fixedly connected to the bottom of the main body, a universal wheel fixedly connected to the bottom of the support leg, a sliding groove opened inside the main body, and a moving mechanism, the moving mechanism including a sliding block slidably connected inside the sliding groove, a rack fixedly connected to the top of the main body, a support plate fixedly connected to the top of the sliding block, a first motor fixedly connected to the bottom of the support plate, a gear fixedly connected to the output end of the first motor, a second motor fixedly connected to the right inner wall of the sliding block, a threaded rod fixedly connected to the output end of the second motor, and a limit rod fixedly connected between the left and right inner walls of the sliding block.
[0005] As a further improvement to the above solution, the end of the threaded rod away from the second motor is rotatably connected to the left inner wall of the sliding block, the gear meshes with the rack, and the sliding groove is opened on the left and right inner walls of the main body.
[0006] The above technical solution can start the first motor to drive the gear to rotate, which in turn drives the gear to mesh with the rack so that the sliding block can slide inside the sliding groove. At the same time, the second motor can be started to drive the threaded rod to rotate, and the threaded rod drives the threaded connecting plate to move, thereby adjusting the position of the laser positioning mechanism.
[0007] As a further improvement to the above solution, a laser positioning mechanism is provided at the bottom of the main body. The laser positioning mechanism includes a threaded connecting plate that is threaded to the outside of the threaded rod. A fixing plate is fixedly connected to the bottom of the threaded connecting plate. A third motor is fixedly connected to the inner wall of the right side of the fixing plate. A first sliding frame is fixedly connected to the output end of the third motor.
[0008] The above technical solution can move the fixed plate while the threaded connecting plate moves, or it can start the third motor to drive the first sliding frame to rotate inside the fixed plate, so that the first sliding frame drives the laser emitter to rotate.
[0009] As a further improvement to the above solution, a rotating groove is provided on the surface of the first sliding frame, and the side of the first sliding frame away from the third motor is rotatably connected to the inner left wall of the fixed plate.
[0010] As a further improvement to the above solution, a fourth motor is fixedly connected to the inner wall of the front side of the fixed plate, a second sliding frame is fixedly connected to the output end of the fourth motor, a first slider is fixedly connected to the bottom of the fixed plate, a grooved rotating ball is slidably connected to the outside of the first slider, a second sliding groove is slidably connected to the inside of the grooved rotating ball, and a laser emitter is fixedly connected to the outside of the second sliding groove.
[0011] With the above technical solution, the laser emitter can be rotated by starting the fourth motor to drive the second sliding frame. At this time, the second slide slides inside the grooved rotating ball. When both the third and fourth motors are started, the laser emitter can have a larger position adjustment angle.
[0012] As a further improvement to the above solution, the surface of the second sliding frame is provided with a moving groove, and the width of the moving groove is the same as that of the rotating groove provided in the first sliding frame. The second sliding groove is slidably connected inside the first sliding frame and the second sliding frame.
[0013] As a further improvement to the above solution, the outer surface of the grooved rotating ball is provided with intersecting grooves, and the first slider and the second groove are provided with protrusions on their exteriors, and the two protrusions are slidably connected inside different grooves respectively.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention uses a starting support plate to drive a gear to rotate, and the gear meshes with a rack to move a sliding block inside a sliding groove, thereby adjusting the longitudinal position of the laser positioning mechanism. Then, a second motor is started to drive a threaded rod to rotate, which in turn moves a threaded connecting plate. The threaded connecting plate then moves the entire laser positioning mechanism laterally, allowing it to move to a suitable positioning position, reducing the impact of obstacles on positioning accuracy, and improving the accuracy of the positioning data.
[0016] This invention utilizes a third motor to rotate the first sliding frame inside the fixed plate. Simultaneously, the first sliding frame rotates the laser emitter inside the second sliding frame, causing the protrusion on the outside of the second sliding groove to slide within the groove of the grooved rotating ball. Then, a fourth motor rotates the second sliding frame, causing the laser emitter to slide inside it. The second sliding groove then causes the grooved rotating ball to slide outside the protrusion on the first slider. This allows the laser emitter to rotate synchronously within both the first and second sliding frames, expanding the laser emitter's angle adjustment range and making the positioning angle more precise.

[0028] The end of the threaded rod 207 away from the second motor 206 is rotatably connected to the left inner wall of the sliding block 201. The gear 205 meshes with the rack 202. The sliding groove 13 is opened on the left and right inner walls of the main body 1.
[0029] The bottom of the main body 1 is provided with a laser positioning mechanism 3. The laser positioning mechanism 3 includes a threaded connecting plate 301 that is threaded to the outside of the threaded rod 207. A fixing plate 302 is fixedly connected to the bottom of the threaded connecting plate 301. A third motor 303 is fixedly connected to the inner wall of the right side of the fixing plate 302. A first sliding frame 304 is fixedly connected to the output end of the third motor 303.
[0030] The surface of the first sliding frame 304 is provided with a rotating groove, and the side of the first sliding frame 304 away from the third motor 303 is rotatably connected to the inner left side of the fixed plate 302.
[0031] A fourth motor 305 is fixedly connected to the inner wall of the front side of the fixed plate 302. A second sliding frame 306 is fixedly connected to the output end of the fourth motor 305. A first slider 307 is fixedly connected to the bottom of the fixed plate 302. A grooved rotating ball 308 is slidably connected to the outside of the first slider 307. A second slide groove 309 is slidably connected to the inside of the grooved rotating ball 308. A laser emitter 3010 is fixedly connected to the outside of the second slide groove 309.

[0034] The implementation principle of a high-precision laser positioning device in this application embodiment is as follows: First, the device is moved above the position of the material to be positioned by the universal wheel 12. During laser positioning, if the position is not suitable for the target position, the support plate 203 can be activated to drive the gear 205 to rotate. The gear 205 meshes with the rack 202 to drive the sliding block 201 to move inside the sliding groove 13, thereby adjusting the longitudinal position of the laser positioning mechanism 3.

At this time, the fourth motor 305 is turned on to drive the second sliding frame 306 to rotate, causing the second sliding frame 306 to drive the laser emitter 3010 to slide inside the second sliding frame 306. At this time, the second sliding groove 309 drives the grooved rotating ball 308 to slide outside the protrusion on the first slider 307, so that the laser emitter 3010 can rotate synchronously inside the first sliding frame 304 and the second sliding frame 306, thus expanding the rotation angle of the laser emitter 3010.
