[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figures 1 to 5 As shown in this embodiment, a handheld profilometer measurement auxiliary fixture includes a profilometer body 1. A laser measurement component 2, which emits laser light and measures the surface of an object, is mounted on the profilometer body 1. A mounting rod 3 is movably mounted on the top of the profilometer body 1, and the mounting rod 3 is rotatably connected to the profilometer body 1. A connecting rod 4 is rotatably mounted on the top of the mounting rod 3, and a handgrip 5 is rotatably mounted on the end of the connecting rod 4 away from the mounting rod 3. The mounting rod 3, connecting rod 4, and handgrip 5 form an auxiliary frame. This auxiliary frame can be disassembled and assembled from the profilometer body 1 to improve the convenience of the profilometer body 1. By rotating the profilometer body 1 in the X and Y planes, Z and Y planes, and Z and X planes respectively, omnidirectional rotation of the profilometer body 1 can be achieved, facilitating omnidirectional measurement and use of the object surface by the auxiliary frame and the profilometer body 1.
[0023] like Figures 1 to 5As shown, the top of the profilometer body 1 has a mounting groove 6, and a mounting ring 7 is rotatably mounted inside the mounting groove 6. The mounting ring 7 is locked inside the mounting groove 6. The top of the mounting rod 3 has a sliding hole 8, and a sliding rod 9 is slidably mounted inside the sliding hole 8. A spring 10 is fixedly mounted on the top of the sliding rod 9, and the top of the spring 10 is fixedly connected to the top of the corresponding sliding hole 8 of the mounting rod 3. The bottom of the sliding rod 9 has a transmission rod 11 rotatably mounted in a ring array around the central axis of the sliding rod 9. The bottom of the mounting rod 3 has a transmission rod 11 rotatably mounted in a ring array around the central axis of the sliding rod 9. The central axis is provided with a ring array of positioning holes 12. A positioning rod 13 is slidably installed inside the positioning holes 12. The end of the transmission rod 11 away from the slide rod 9 is fixedly connected to the end of the positioning rod 13 by a shaft pin. The mounting ring 7 is provided with a ring array of insertion holes 14 with the central axis of the mounting ring 7 as the axis. The insertion holes 14 are slidably inserted into the end of the positioning rod 13 away from the transmission rod 11. The end of the positioning rod 13 away from the transmission rod 11 is provided with a chamfer 15. The top of the slide rod 9 is integrally fixed with a protrusion 16, which passes through the mounting rod 3.
[0024] Insert the mounting rod 3 into the mounting slot 6 on the top of the profilometer body 1. Simultaneously, the lifting protrusion 16 raises the sliding rod 9. At this point, the connection between the positioning rod 13 and the sliding rod 9 via the transmission rod 11 causes the positioning rod 13 to slide inside the positioning hole 12, thus storing the positioning rod 13 inside the positioning hole 12. At this time, the spring 10 is compressed. Insert the mounting rod 3 completely into the mounting slot 6, remove the lifting protrusion 16, and the spring 10 pushes the sliding rod 9, causing it to slide downwards inside the sliding hole 8. The connection between the positioning rod 13 and the sliding rod 9 via the transmission rod 11 causes the positioning rod 13 to slide downwards inside the positioning hole 12. The internal reverse sliding will cause the positioning rod 13 to be inserted into the insertion hole 14 on the mounting ring 7. This can be used to assemble the auxiliary frame consisting of the mounting rod 3, connecting rod 4, and hand grip rod 5 with the profilometer body 1. Then, the lifting protrusion 16 will drive the slide rod 9 to rise. At this time, the connection between the positioning rod 13 and the slide rod 9 through the transmission rod 11 will cause the positioning rod 13 to slide inside the positioning hole 12. The positioning rod 13 will slide out of the insertion hole 14 on the mounting ring 7. The auxiliary frame consisting of the mounting rod 3, connecting rod 4, and hand grip rod 5 can be removed from the mounting groove 6 on the profilometer body 1 for disassembly between the auxiliary frame and the profilometer body 1.
[0025] like Figures 1 to 5 As shown, a first motor 27 is fixedly installed inside the bottom end of the mounting rod 3, and a first hexagonal plug 28 is fixedly installed at the output end of the first motor 27. A first hexagonal slot 29 is provided at the bottom end of the profilometer body 1 corresponding to the mounting groove 6, and the first hexagonal slot 29 is slidably inserted into the first hexagonal plug 28.
[0026] The first motor 27 drives the first hexagonal plug 28 to rotate. Since the first hexagonal plug 28 is inserted into the first hexagonal slot 29, it will drive the profilometer body 1 to rotate around the central axis of the mounting ring 7, thereby realizing the rotation of the profilometer body 1 in the X and Y planes.
[0027] like Figures 1 to 5 As shown, the end of the connecting rod 4 is provided with a mounting hole 17, the top of the mounting rod 3 is rotatably installed inside the mounting hole 17, a second motor 18 is fixedly installed on one side of the connecting rod 4, a second hexagonal plug 19 is fixedly installed at the output end of the second motor 18, a second hexagonal slot 20 is provided at the top of the mounting rod 3, and the second hexagonal slot 20 and the second hexagonal plug 19 are slidably inserted into each other.
[0028] The second motor 18 drives the second hexagonal plug 19. Since the second hexagonal plug 19 is inserted into the second hexagonal slot 20, it will drive the installation rod 3 to rotate, thereby driving the profiler body 1 to rotate in the Z and Y planes.
[0029] like Figures 1 to 5 As shown, a connecting bearing 21 is installed on the outer side of one end of the grip rod 5. The connecting bearing 21 is located inside the end of the connecting rod 4 away from the mounting hole 17. A third hexagonal slot 22 is provided inside the connecting rod 4. A third motor 23 is fixedly installed inside the end of the grip rod 5 near the connecting rod 4. A third hexagonal plug 24 is fixedly installed at the output end of the third motor 23. The third hexagonal plug 24 is slidably inserted into the third hexagonal slot 22.
[0030] The third motor 23 drives the third hexagonal plug 24 to rotate. Since the third hexagonal plug 24 is inserted into the third hexagonal slot 22, it will drive the mounting rod 3, the profilometer body 1 and the connecting rod 4 to rotate in the Z and X planes.
[0031] like Figures 1 to 5 As shown, a controller 25 is fixedly installed on the hand grip 5, and a control button 26 is electrically installed on the controller 25.
[0032] By operating the control button 26, the controller 25 can control the forward and reverse rotation of the first motor 27, the second motor 18, and the third motor 23, thereby realizing the automatic rotation of the contouring instrument body 1 in all directions.
[0033] This utility model provides a handheld profilometer measurement auxiliary fixture, the specific working principle of which is as follows:
[0034] When using the device, with the auxiliary frame consisting of mounting rod 3, connecting rod 4, and handgrip 5, the mounting rod 3 is inserted into the mounting slot 6 on the top of the profilometer body 1. Simultaneously, the lifting protrusion 16 causes the sliding rod 9 to rise. At this time, the connection between the positioning rod 13 and the sliding rod 9 via the transmission rod 11 causes the positioning rod 13 to slide inside the positioning hole 12, thus storing the positioning rod 13 inside the positioning hole 12. At this time, the spring 10 is compressed, and the mounting rod 3 is fully inserted into the mounting slot 6. The lifting protrusion 16 is then removed, and the spring 10 pushes the sliding rod 9, causing it to slide downwards inside the sliding hole 8. The connection between the positioning rod 13 and the sliding rod 9 via the transmission rod 11 causes the positioning rod 13 to slide in the opposite direction inside the positioning hole 12, thus inserting the positioning rod 13 into the insertion hole 14 on the mounting ring 7. This can be used when using the mounting rod 3, connecting rod 4, and handgrip 5. The auxiliary frame consisting of the 4 and the handgrip 5 is assembled with the profilometer body 1. Then, the handgrip 5 is held, and the first hexagonal plug 28 is rotated by the first motor 27. Since the first hexagonal plug 28 is inserted into the first hexagonal slot 29, it will drive the profilometer body 1 to rotate around the central axis of the mounting ring 7, realizing the rotation of the profilometer body 1 in the X and Y planes. Then, the second hexagonal plug 19 is driven by the second motor 18. Since the second hexagonal plug 19 is inserted into the second hexagonal slot 20, it will drive the mounting rod 3 to rotate, thereby driving the rotation of the profilometer body 1 in the Z and Y planes. The third hexagonal plug 24 is driven by the third motor 23. Since the third hexagonal plug 24 is inserted into the third hexagonal slot 22, it will drive the mounting rod 3, the profilometer body 1 and the connecting rod 4 to rotate in the Z and X planes, realizing the omnidirectional rotation of the profilometer body 1.
[0035] When the auxiliary frame consisting of mounting rod 3, connecting rod 4 and hand grip rod 5 is removed from the profilometer body 1, the lifting protrusion 16 drives the slide rod 9 to rise. At this time, the connection between the positioning rod 13 and the slide rod 9 through the transmission rod 11 will cause the positioning rod 13 to slide inside the positioning hole 12. The positioning rod 13 will slide out of the insertion hole 14 on the mounting ring 7, and the auxiliary frame consisting of mounting rod 3, connecting rod 4 and hand grip rod 5 can be taken out from the mounting groove 6 on the profilometer body 1.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
