[0027] Embodiment 1:

[0028] The measuring units in the existing tire profile measuring devices are all fixed, so that the tire sizes that can be measured are all restricted by the fixed measuring devices. Tires of different sizes require corresponding different measuring devices, and the tire diameters that can be measured are also limited. The diameter of truck tires is usually larger, so this fixed tire profile measuring device cannot be used in the measurement of truck tire profiles.

[0029] In order to solve the above technical problems, a truck tire profile measuring device is provided in Embodiment 1 of the present invention. Figure 1 -Attached Figure 3 It is understood that it includes a bottom plate 1, a main support frame 2, a back plate 3, a visual measurement mechanism 4 arranged in pairs, an X-direction moving mechanism 5, a Y-direction moving mechanism 6, a Z-direction moving mechanism 7 and a control mechanism; the back plate 3 is vertically fixed on the main support frame 2; the X-direction moving mechanism 5 is arranged on the bottom plate 1; the main support frame 2 is slidably arranged on the bottom plate 1 through the Y-direction moving mechanism 6; the visual measurement mechanisms 4 arranged in pairs are symmetrically arranged on the back plate 3, and there is a gap between the visual measurement mechanisms 4 for accommodating truck tires, the Z-direction moving mechanism 7 is arranged on the back plate 3, and the symmetrically arranged visual measurement mechanisms 4 can be synchronously moved on the back plate 3 through the Z-direction moving mechanism 7; the control mechanism is electrically connected to the visual measurement mechanism 4, the X-direction moving mechanism 5, the Y-direction moving mechanism 6, and the Z-direction moving mechanism 7. Among them, the outside of the measuring device is also covered with a protective cover 8. The present invention provides a truck tire profile measuring device. When in use, when the truck to be tested stops at the test station, the visual measuring mechanism 4 will move to the front axle and rear axle wheels respectively according to the wheelbase information of the vehicle, and obtain the size of the truck tire to be tested according to the vehicle parameters preset by the control mechanism. The visual measuring mechanism 4 runs to the measurement position set by the program, thereby measuring the profile of the truck tire. The present invention sets the visual measuring mechanism 4 and each moving mechanism, and the visual measuring mechanism 4 can move with the change of the outer diameter of the truck tire to change the coordinates of its position so that it stops at the set measurement position, so that the position is adjusted under the action of each moving mechanism to adapt to the measurement of truck tires of different specifications. The structure design is reasonable, the operation is simple and flexible, and the parameters of the truck tire profile can be measured quickly and accurately. It can also measure trucks of various specifications in a single inspection line of an automobile factory without changing the line, thereby greatly improving the inspection efficiency, thereby effectively solving the problem that the tire profile measuring device in the prior art is a fixed tire profile measuring device and cannot be applied to the measurement of the truck tire profile.

[0030] Furthermore, the visual measurement mechanism 4 includes an industrial measurement 3D camera 41 and a camera mounting frame 42; the industrial measurement 3D camera 41 is arranged on the Z-direction moving mechanism 7 through the camera mounting frame 42.

By arranging the industrial measurement 3D camera 41, the camera mounting frame 42 and the displacement sensors, and controlling the motion accuracy of the industrial measurement 3D camera 41 through the displacement sensors, the working reliability of the measuring device is effectively improved.

[0031] Furthermore, the Z-axis moving mechanism 7 includes a servo motor 71, a pair of pulley transmission assemblies 72, a pair of linear motion guide assemblies 73 and a pair of connecting sliding assemblies 74; the servo motor 71 is arranged on the back plate 3; the pair of pulley transmission assemblies 72 are symmetrically arranged on the back plate 3, and the pulley transmission assemblies 72 are transmission-connected to the servo motor 71; the pair of linear motion guide assemblies 73 are symmetrically arranged on the back plate 3, and any linear motion guide assembly 73 is arranged on one side of the pulley transmission assembly 72 close to the edge of the back plate 3; one end of the connecting sliding assembly 74 is connected to the visual measurement mechanism 4, and the other end is connected to the pulley transmission assembly 72, and is slidably arranged on the linear motion guide assembly 73.

At the same time, the linear motion guide assembly 73 can play a guiding role, that is, the visual measurement mechanism 4 can move on the preset linear track.

[0032] Furthermore, the pulley transmission assembly 72 includes a plurality of synchronous pulleys 721, synchronous belts 722 and steering guide wheels; the synchronous pulleys 721 are rotatably arranged on the back plate 3; the synchronous belts 722 are wound around the synchronous pulleys 721 and the steering guide wheels; the back plate 3 is provided with connecting grooves 31 arranged in pairs, and synchronous pulleys 721 are respectively arranged at both ends of the connecting grooves 31, and the connecting sliding assembly 74 is penetrated in the connecting grooves 31 and detachably fixed on the synchronous belts 722. Among them, there are two connecting grooves 31, which are symmetrically arranged on the back plate 3, and the top spacing of the two connecting grooves 31 is greater than the bottom spacing. By arranging the synchronous pulleys 721, the synchronous belts 722 and the steering guide wheels, the structure is relatively simple, easy to set up, and the transmission is stable, which can reduce the impact and vibration loads, thereby further improving the working stability and reliability of the measuring device. Specifically, in this embodiment, the connecting grooves 31 on both sides are arranged in a V shape, and the synchronous belt 722 and the linear motion guide assembly 73 are also arranged in a V shape, so that the visual measurement mechanism 4 can move along the V-shaped guide rail as the outer diameter of the truck tire changes.

Further, the X-direction moving mechanism 5 includes an X-direction travel drive motor 51 and a transmission assembly; the X-direction travel drive motor 51 is arranged on the bottom plate 1; the transmission assembly is arranged at the bottom of the bottom plate 1, and the transmission assembly is connected to the X-direction travel drive motor 51. When the tire profile measuring device needs to be adjusted as a whole on the detection line, the above-mentioned arrangement can realize the movement in the X-direction and Y-direction, thereby adapting to the measurement of the tire profiles of trucks of different specifications, and further improving the applicability of the device.

[0035] In summary, the present invention provides a truck tire profile measuring device. By setting a visual measuring mechanism and various moving mechanisms, the visual measuring mechanism can move as the outer diameter of the truck tire changes, so as to change the coordinates of its position so that it stops at a set measurement position, thereby adjusting its position under the action of various moving mechanisms to adapt to the measurement of truck tires of different specifications.
