Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser radar assembly, in particular to a magnetic ring mounting tool and a magnetic ring mounting method. BACKGROUND

[0002] The mechanical laser radar is based on a fixed structure, mainly composed of a main body and a main shaft. A motor stator is assembled on the main shaft, and a magnetic steel is installed on the main body as a rotor. The main body and the main shaft transmit power and signals through the power transmission magnetic ring and the signal transmission magnetic ring. The relative position between the magnetic rings directly affects the power transmission and signal transmission when they are coupled. Therefore, the installation position of the magnetic ring on the main shaft has a great influence on the power transmission and signal transmission of the whole radar during operation.

[0003] Currently, the installation method of the magnetic ring on the main shaft of the mechanical laser radar mainly uses different thickness spacers between the power transmission magnetic ring and the signal transmission magnetic ring. By continuously trying different combinations of spacers, the magnetic ring is installed within the designed tolerance range, so that the magnetic rings are fully coupled and can normally transmit power and signals. This method requires a lot of time to adjust the spacers between the magnetic rings, and needs to continuously try different combinations of spacers to make the magnetic ring reach the predetermined position. Since it is installed manually, the magnetic ring is prone to uneven force during installation and pressing, which may cause the coupling surface of the magnetic ring to tilt. The tilt of the magnetic ring may cause the magnetic ring to be too close during coupling, and may cause friction between the magnetic ring and the main body, resulting in abnormal noise during radar operation. At the same time, the tilt of the magnetic ring may change the coupling state and affect the power transmission and signal transmission of the radar. SUMMARY

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

When the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope claimed by the present application.

[0058] At present, the installation method of the magnetic ring on the main shaft of the mechanical laser radar mainly pads some pads with different thicknesses between the power transmission magnetic ring and the signal transmission magnetic ring, and through continuous attempts on the combination of pads with different thicknesses, the magnetic ring is installed within the designed tolerance range, so that the coupling between the magnetic rings is sufficient, and the related functions of power transmission and signal transmission are normally performed. This method needs to spend a lot of time in adjusting the pads between the magnetic rings during the trial process, and needs to continuously try the combination of pads with different thicknesses to make the magnetic ring reach the predetermined position. And because it is installed manually, the magnetic ring is prone to uneven force during the installation and pressing process, which causes the coupling surface of the magnetic ring to tilt. Please refer to Figure 1 , the tilt of the magnetic ring will cause the magnetic ring to be too close during coupling and rub against the main body, producing abnormal noise during radar operation. At the same time, the tilt of the magnetic ring will change the coupling state and affect the power transmission and signal transmission of the radar.

[0059] In order to solve the above problems, the present application provides a magnetic ring installation tool for installing a magnetic ring on a laser radar main shaft 1000 extending in a first direction,Figures 2 to 5 The specific embodiment of the magnetic ring mounting tool provided by the application.

[0060] Please refer to Figures 1 to 3 , the magnetic ring mounting tool comprises a mounting seat 1, a fixing assembly 2 and at least one positioning part 3, the fixing assembly 2 is mounted on the mounting seat 1 and is used for fixing the laser radar main shaft 1000, the fixing assembly 2 comprises a first limiting structure 21 and a second limiting structure 22 which are arranged at intervals in a first direction, the first limiting structure 21 is used for limiting the first end of the laser radar main shaft 1000, and the second limiting structure 22 is used for limiting the second end of the laser radar main shaft 1000; the positioning part 3 is mounted on the mounting seat 1, and the positioning part 3 has a positioning surface 3a arranged corresponding to the mounting position of the magnetic ring, and the positioning surface 3a is used for abutting against the end surface of the magnetic ring, so that the magnetic ring can be positioned at the mounting position.

[0061] In the technical scheme provided by the application, the fixing assembly 2 comprises a first limiting structure 21 and a second limiting structure 22 which are arranged at intervals in a first direction, the first limiting structure 21 limits the first end of the laser radar main shaft 1000, and the second limiting structure 22 limits the second end of the laser radar main shaft 1000, so as to fix the laser radar main shaft 1000 on the mounting seat 1, at least one positioning part 3 is arranged on the mounting seat 1, the positioning part 3 has a positioning surface 3a arranged corresponding to the mounting position of the magnetic ring, and the positioning surface 3a is used for abutting against the end surface of the magnetic ring, when it is needed to mount the magnetic ring, the area of the outer periphery of the laser radar main shaft 1000 which needs to be bonded with the magnetic ring is coated with adhesive, the magnetic ring is sleeved on the outer periphery of the laser radar main shaft 1000 when the adhesive is not dry, then the end surface of the magnetic ring is abutted against the positioning surface 3a, so that the magnetic ring is positioned at the position to be bonded, after the adhesive is solidified, the mounting of the magnetic ring is completed, and by abutting the magnetic ring against the positioning surface 3a, the magnetic ring can be accurately positioned at the position to be mounted, so as to provide a magnetic ring mounting tool which can conveniently and accurately mount the magnetic ring on the laser radar main shaft 1000.

[0062] It can be understood that the positioning surface 3a is consistent with the position of the magnetic ring to be mounted, and when a plurality of magnetic rings need to be mounted on the laser radar main shaft 1000, the positions of the magnetic rings in the axial direction of the laser radar main shaft 1000 are different, therefore, the positioning surface 3a is arranged at the mounting position required by the corresponding magnetic ring.

[0063] Specifically, in order to enable the end face of the magnetic ring to maintain sufficient contact with the positioning face 3a and avoid tilting of the magnetic ring, in the embodiment, the positioning portion 3 is arranged between the first limiting structure 21 and the second limiting structure 22, the positioning portion 3 is provided with a through hole along the first direction, the mounting hole is used for penetrating the laser radar main shaft 1000, and an end face of the positioning portion 3 in the first direction is provided as the positioning face 3a. In this way, when the magnetic ring is positioned, the magnetic ring can be sleeved on the laser radar main shaft 1000, and then the magnetic ring is pushed to abut against the positioning face 3a. Since the positioning face 3a is located on the side of the laser radar main shaft 1000, the entire end face of the magnetic ring can abut against the positioning face 3a, tilting is avoided, friction between the main body and the magnetic ring is avoided, abnormal sound is avoided, and the coupling state is not affected.

[0064] Further, in order to facilitate installation, in the embodiment, the positioning portion 3 includes an upper positioning block 31 and a lower positioning block 32, the lower positioning block 32 is installed on the mounting seat 1, and the upper positioning block 31 is detachably installed on the lower positioning block 32. A first installation groove a is arranged at a lower end of the upper positioning block 31, the first installation groove a penetrates the upper positioning block 31 along the first direction, and an inner wall of the first installation groove a is used for adapting to an upper circumferential wall of the laser radar main shaft 1000. A second installation groove b is arranged at an upper end of the lower positioning block 32, the second installation groove b penetrates the lower positioning block 32 along the first direction, and an inner wall of the second installation groove b is used for adapting to a lower circumferential wall of the laser radar main shaft 1000. The first installation groove a and the second installation groove b surround to form the through hole. In this way, before the laser radar main shaft 1000 needs to be fixed, the upper positioning block 31 and the lower positioning block 32 can be detached and separated, then the laser radar main shaft 1000 is erected on the second installation groove b, and finally the upper positioning block 31 is installed on the lower positioning block 32, so that the upper circumferential wall of the laser radar main shaft 1000 is adapted to the first installation groove a.

[0065] It can be understood that when the magnetic ring needs to be removed after being installed, the upper positioning block 31 can also be detached, which is convenient for removal.

[0066] Specifically, the detachable specific form between the upper positioning block 31 and the lower positioning block 32 is more, which can be through clamping, screwing and the like, in the embodiment, the end of the upper positioning block 31 and the lower positioning block 32 close to each other is provided with a positioning pin hole c, the upper positioning block 31 and the lower positioning block 32 are connected through a pin 4 penetrating the two positioning pin holes c. In this way, the lower half of the pin 4 can be penetrated into the positioning pin hole c on the lower positioning block 32, and then the positioning pin hole c of the upper positioning block 31 is aligned with the upper end of the pin 4 and is pressed down, so that the upper positioning block 31 can be conveniently and quickly assembled with the lower positioning block 32.

[0067] It can be understood that after the upper positioning block 31 and the lower positioning block 32 are combined and installed, the side surface of the same side of the upper positioning block 31 and the lower positioning block 32 forms the positioning surface 3a together, therefore, the side surface of the upper positioning block 31 and the lower positioning block 32 remains aligned.

[0068] Further, when a plurality of magnetic rings need to be installed on the laser radar main shaft 1000, in order to facilitate quick corresponding different magnetic rings to set different abutting reference surfaces, in the embodiment, the positioning part 3 is detachably installed on the mounting seat 1. In this way, after one magnetic ring is installed, the positioning part 3 can be detached and replaced with other positioning part 3, so that different magnetic rings can be accurately positioned through the positioning surface 3a on different positioning parts 3.

[0069] Specifically, in the embodiment, the upper side of the mounting seat 1 is provided with a limiting groove d, and the positioning part 3 is clamped in the limiting groove d. The limiting groove d can be two first limiting protrusions arranged at two sides of the first direction on the mounting seat 1, and the limiting groove d is formed between the two first limiting protrusions, and a second limiting protrusion for abutting the positioning part 3 can also be arranged on the mounting seat 1, the second limiting protrusion is located at one end of the two first limiting protrusions, avoiding the positioning part 3 from moving along the first direction when clamped between the two first limiting protrusions, and the second limiting protrusion facilitates positioning the positioning part 3 in the first direction.

[0070] Specifically, the transmission electromagnetic ring 200 and the signal transmission magnetic ring 300 are generally required to be installed on the laser radar main shaft 1000, and the transmission electromagnetic ring 200 and the signal transmission magnetic ring 300 are arranged in the axial direction of the laser radar main shaft 1000. In order to facilitate accurate installation of both magnetic rings, the positioning portion 3 is provided with a plurality of positioning portions 3 in the embodiment, and the plurality of positioning portions 3 include a first positioning portion 301 and a second positioning portion 302, and the first positioning portion 301 and the second positioning portion 302 are alternatively installed on the mounting seat 1. The first positioning portion 301 has a first positioning surface 301a arranged corresponding to a first installation position of the transmission electromagnetic ring 200, and the first positioning surface 301a is used to abut against the end surface of the transmission electromagnetic ring 200, so that the transmission electromagnetic ring 200 can be positioned at the first installation position. The second positioning portion 302 has a second positioning surface 302a arranged corresponding to a second installation position of the signal transmission magnetic ring 300, and the second positioning surface 302a is used to abut against the end surface of the signal transmission magnetic ring 300, so that the signal transmission magnetic ring 300 can be positioned at the second installation position.

[0071] It can be understood that when the first positioning portion 301 is installed on the mounting seat 1, the plane where the first positioning surface 301a is located is arranged in the first direction with the plane where the second positioning surface 302a is located when the second positioning portion 302 is installed on the mounting seat 1. Based on the fact that the first positioning portion 301 and the second positioning portion 302 are both clamped by the limiting groove d, the shape of the first positioning portion 301 and the second positioning portion 302 can be adjusted adaptively, so that the first positioning surface 301a and the second positioning surface 302a of the first positioning portion 301 and the second positioning portion 302 can adapt to the positions of the end surfaces of the corresponding magnetic rings.

[0072] Specifically, in the embodiment, the first limiting structure 21 includes a limiting block 211 arranged on the mounting seat 1, and the limiting block 211 is provided with a containing groove e adapted to the first end of the laser radar main shaft 1000. The containing groove e is open upward and penetrates through the end surface of the limiting block 211 toward the second limiting structure 22, and the side wall of the containing groove e away from the second limiting structure 22 is used to abut against the first end of the laser radar main shaft 1000. In this way, the first end of the laser radar main shaft 1000 is limited by the side wall of the containing groove e away from the second limiting structure 22, so that the laser radar main shaft 1000 can be kept as a zero point with the side wall as a reference when different magnetic rings are installed each time or when different models of laser radar main shafts 1000 are installed. The position of the positioning surface 3a of the positioning portion 3 can be designed according to the distance between the side wall and the position of the magnetic ring to be installed.

[0073] Further, in the embodiment, the containing groove e is provided with a positioning notch f on the side wall away from the second limiting structure 22 in the first direction. The positioning notch f is provided as a circular arc groove, and the center of the circular arc groove is coaxially arranged with the axis of the laser radar main shaft 1000. It can be understood that the center of the through hole is also coaxially arranged with the laser radar main shaft 1000, so as to ensure that the laser radar main shaft 1000 can extend along the horizontal direction and avoid tilting, and ensure accurate positioning of the magnetic ring.

[0074] Specifically, in the embodiment, the second limiting structure 22 includes a fixing seat 221 and a clamping rod 222. The fixing seat 221 is fixedly arranged on the mounting seat 1. The clamping rod 222 is arranged corresponding to the second end of the laser radar main shaft 1000. The clamping rod 222 is movably arranged on the fixing seat 221 in the first direction, so as to clamp the laser radar main shaft 1000 in the active stroke close to the second end of the laser radar main shaft 1000.

[0075] Based on the above-mentioned magnetic ring mounting tool, the application further provides a magnetic ring mounting method, which comprises the following steps:

[0078] In step S30, the magnetic ring is moved to the area to be installed, and the end face of the magnetic ring is abutted against the positioning face 3a on the positioning part.

[0079] In the technical scheme provided by the application, when the magnetic ring needs to be installed, the area of the laser radar main shaft 1000 to be bonded with the magnetic ring is coated with adhesive, the magnetic ring is sleeved on the outer periphery of the laser radar main shaft 1000 when the adhesive is not dry, and then the end face of the magnetic ring is abutted against the positioning face 3a, so that the magnetic ring is positioned at the position to be bonded. After the adhesive is cured, the installation of the magnetic ring is completed. By abutting the magnetic ring against the positioning face 3a, the magnetic ring can be accurately positioned at the position to be installed.

[0080] Further, in yet another embodiment, the positioning part is detachably mounted on the mounting seat 1, and a plurality of positioning parts are provided, including a first positioning part 301 and a second positioning part 302, which are alternatively mounted on the mounting seat 1, the first positioning part 301 is provided with a first positioning surface 301a corresponding to the first mounting position of the power transmission magnetic ring 200, and the second positioning part 302 is provided with a second positioning surface 302a corresponding to the second mounting position of the signal transmission magnetic ring 300.
