[0036] The application scenario of the present application is mainly based on a car tire balancing machine, and can also be applied to other scenarios according to its functions. Its application scenario is not restricted or limited by the specific embodiments described in the present application.

[0037] 2. Based on the fact that the angle of the laser device installed in the current automobile tire balancing machine cannot be adjusted or there are many inconveniences in the adjustment process, the laser is emitted at only one point, and the corresponding position on the tire is limited. The commonality itself is low and it cannot meet the use requirements of tires of different specifications. There are problems of inconvenience in use. This application specifically provides a technical solution to the above-mentioned problem. The technical solution, working principle and technical effect of this application are described in detail below in combination with specific embodiments.

[0038] This embodiment describes a laser positioning device for a tire balancing machine. Figure 2 As shown, when in use, it is installed on the main shaft of the tire balancing machine body, and the position of the laser 1 on the tire can be adjusted by adjusting the installation angle of the laser 1 to meet the use requirements of different tire specifications.

[0039] like Figure 1 , Figure 3As shown, the laser positioning device of the tire balancing machine includes a mounting base, a laser component, and an angle adjustment component, wherein the laser component and the angle adjustment component are mounted inside the mounting base. In order to meet the use requirements of tires of different specifications, the laser component adopts a structural design with adjustable mounting angle.

[0040] The laser assembly includes a laser 1 and a rotating shaft 2 . The laser 1 is rotatably mounted on a mounting base via the rotating shaft 2 and can rotate along with the rotating shaft 2 .

[0041] The angle adjustment component is a driving mechanism, and the angle adjustment component is arranged on one side of the laser 1 and is used to adjust the installation angle of the laser component.

[0042] In order to be able to be assembled on the main shaft of the tire balancing machine without affecting the normal rotation of the main shaft, the mounting base adopts a combined structure design of a laser component mounting seat 3 and a main shaft mounting seat 4 in structural design, and the laser component mounting seat 3 and the main shaft mounting seat 4 adopt an integrated combined structure. Of course, a detachable structural combination can also be adopted.

[0043] In this embodiment, as a preferred solution, the laser assembly mounting seat 3 and the spindle mounting seat 4 are integrated into a structure. This design is convenient for installation and disassembly, and can ensure the consistency of the installation position of the laser 1 and the mounting base, improve the accuracy of the laser 1 aiming, and facilitate the positioning of the balance block.

[0044] The laser assembly mounting seat 3 is provided with a front cover 31 and a rear cover 32, and the front cover 31 and the rear cover 32 are detachably connected, and the front cover 31 is buckled with the rear cover 32 by a buckle. When the laser assembly fails, the front cover 31 can be directly opened for replacement or repair, which is convenient and quick to open.

[0045] In this embodiment, the laser 1 can be adjusted in the height direction. In order to facilitate the adjustment of the installation height of the laser component, two mounting plates 5 are arranged side by side in the vertical direction on one side of the rear end cover 32 close to the front end cover 31. The laser 1 is arranged between the two mounting plates 5 and installed on the two mounting plates 5. The installation height of the laser 1 on the mounting plate 5 is adjustable to meet the requirements of the installation height of the laser 1.

[0046] The adjustment of the pitch angle of the laser 1 is achieved through an angle adjustment component. In order to facilitate the installation of the angle adjustment component, a mounting hole 6 is opened on one of the two mounting plates 5 vertically arranged near the rear end cover 32, and the mounting hole 6 is used to install the angle adjustment component.

[0047] Preferably, the angle adjustment component uses a stepper motor 9 , and a power output end of the stepper motor 9 is connected to the rotating shaft 2 of the laser component to drive the laser 1 to rotate along the rotating shaft 2 .

[0048] When the tire size is too large, the stepper motor 9 is started, and the stepper motor 9 drives the rotating shaft 2 of the laser assembly to rotate. The rotation of the rotating shaft 2 drives the laser 1 to rotate, and then the emission angle of the laser beam is adjusted until the beam irradiates the positions on both sides of the tire. The stepper motor 9 stops working and the adjustment of the beam angle is completed.

[0049] The spindle mounting seat 4 is designed to facilitate the combined installation between the laser assembly and the tire balancing machine spindle, wherein the spindle mounting seat 4 includes a mounting cover 41, which is arranged above the rear end cover 32 and forms an integral structure with the rear end cover 32.

[0050] The mounting cover 41 is provided with a mounting groove 411, which is a downwardly concave arc structure, and the arc structure of the mounting groove 411 fits with the bottom of the main shaft of the balancing machine to support the main shaft of the tire balancing machine. When working, the main shaft of the tire balancing machine rotates along the mounting groove 411.

[0051] As an optimization, a top cover 7 is provided on the upper part of the mounting cover 41 , and a detachable combined connection is adopted between the top cover 7 and the mounting cover 41 , and the top cover 7 is connected to the mounting cover 41 by fastening screws.

[0052] The top cover 7 is an upwardly protruding arc-shaped structure, and the arc-shaped structure of the top cover 7 fits with the upper part of the main shaft of the balancing machine.

[0053] As a further optimization, a groove 311 matching the mounting groove 411 is formed on the upper portion of the front cover 31. After the front cover 31 and the rear cover 32 are assembled and installed, the groove 311 of the front cover 31 fits with the mounting groove 411 of the mounting cover 41, and the front cover 31, the rear cover 32 and the mounting cover 41 together constitute a protective housing of the laser assembly.

[0054] The front end cover 31 is provided with a laser beam outlet 312 corresponding to the installation position of the laser 1, and a light-transmitting plate 8 is provided at the laser beam outlet 312. The light-transmitting plate 8 is made of a transparent plastic plate. The light-transmitting plate 8 is installed at the laser beam outlet 312 of the front end cover 31. The laser emitted by the laser 1 can pass through the light-transmitting plate 8 and irradiate the tire.

[0055] Combined with the above description of the structure and technical effects, the specific angle adjustment method of the laser positioning device of the tire balancing machine of the present application is as follows:

[0056] The device is used in conjunction with the main shaft of the tire balancing machine. During installation, firstly, the mounting groove 411 of the main shaft mounting seat 4 is fitted with the main shaft, and then the top cover 7 is connected and fixed to the mounting groove 411 and the upper part of the main shaft by fastening screws to complete the fixing of the mounting base on the main shaft.

[0057] When it is necessary to adjust the vertical position of the laser 1, it is necessary to open the front cover 31, and adjust the relative height of the laser 1 in the vertical direction by adjusting the installation position of the laser 1 on the two vertically arranged mounting plates 5. After the adjustment is completed, tighten the fixing screws and buckle the front cover 31 to complete the adjustment of the laser 1 in the vertical height direction.

[0058] When the pitch angle of the laser 1 needs to be adjusted, the laser is turned on, the stepper motor 9 is started, and the position of the linear laser is adjusted according to the size of the tire. During adjustment, the stepper motor 9 rotates to drive the rotating shaft 2 of the laser assembly to rotate, and the rotating shaft 2 drives the pitch angle of the laser beam of the laser emitter to change until the laser beam irradiates the positions on both sides of the tire, completing an angle adjustment.

[0059] like Figure 3 , Figure 4 As shown, two contrasting states of the angle adjustment of the laser 1 are shown.

[0060] It should be noted that during the entire working process, the angle of the laser 1 does not need to be adjusted all the time. It is only adjusted when the tire sizes differ too much to prevent the two sides of the tire from being missed.

[0061] In summary, the laser positioning device of the tire balancing machine can adjust the linear laser to shine the laser on the tire, making it easier for the user to stick to the exact position. The position of the laser on the tire can be adjusted to meet the needs of different tire specifications.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0063] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
