Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.
[0030] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, elements, components, and / or groups thereof, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.
[0031] Referring to Figures 1-7 The utility model provides a technical scheme:
[0032] An automatic guided vehicle body sensor installation positioning calibration device, including vehicle body installation piece 1 and sensor body 2, be provided with installation mechanism 3 between vehicle body installation piece 1 and sensor body 2, the outside of vehicle body installation piece 1 is provided with rotating mechanism 4, the top of rotating mechanism 4 is provided with angle display mechanism 5;
[0033] Installation mechanism 3 includes installation plate 31, the outside of installation plate 31 is fixedly connected with push plate 35;
[0034] Rotating mechanism 4 includes fixed seat 41, the inside of fixed seat 41 is fixedly connected with link rod 42, the outside of link rod 42 is movably connected with connecting ring 43, torque spring 44 is arranged between link rod 42 and connecting ring 43, the outside of connecting ring 43 is fixedly connected with stress plate 45;
[0035] Angle display mechanism 5 includes extension rod 51, the outside of extension rod 51 is fixedly connected with rotating plate 52, the outside of vehicle body installation piece 1 is fixedly connected with fixed plate 53, the outside of fixed plate 53 is fixedly connected with guide rod 54, the tail end top of guide rod 54 is fixedly connected with pointer 55, the outside of guide rod 54 is rotatably connected with scale disc 57.
[0036] It should be noted that: fixed seat 41 is fixedly connected on the outside of vehicle body installation piece 1, stress plate 45 is installed on the outside of vehicle body installation piece 1 by the cooperation of link rod 42 and torque spring 44, extension rod 51 is fixedly connected on the outside of stress plate 45, the top of rotating plate 52 is fixedly connected on the bottom of scale disc 57, scale disc 57 is located between pointer 55 and fixed plate 53, and scale disc 57 is movably connected on the outside of fixed plate 53.
[0037] Further, sensor body 2 and installation plate 31 are fixedly connected, such as welding or high-strength screw locking, which can avoid the loosening and deviation of the sensor during the operation of the device, and the connection between installation plate 31 and vehicle body installation piece 1 is realized by the cooperation of penetrating hole 32 and bolt 33, and penetrating hole 32 is symmetrically distributed inside installation plate 31. This symmetrical design can evenly stress bolt 33 and avoid deformation of installation plate 31 due to uneven stress.
[0038] Specifically, the guide rod 54 is located in the connecting groove 58 inside the dial 57, and the limiting column 56 outside the guide rod 54 rotates in the inner wall of the connecting groove 58, ensuring stable rotation of the dial 57. The fixed seat 41 is fixedly connected to the outside of the vehicle body mounting part 1 as the basis of the rotating mechanism 4, and can provide stable support for the entire rotating assembly. The connecting ring 43 movably connected to the outside of the fixed seat 41 can rotate flexibly around the connecting rod 42, and the torque spring 44 between the connecting rod 42 and the connecting ring 43 plays a dual role of “resetting and restraining”. When there is no external force, the torque spring 44 remains in a natural state, driving the connecting ring 43 and the force receiving plate 45 outside to an initial vertical posture, providing a calibration reference for the mounting mechanism 3. When the mounting plate 31 is connected to the vehicle body mounting part 1, the push plate 35 is in close contact with the force receiving plate 45 and applies a force, and the torque spring 44 will be elastically deformed, restricting the rotation amplitude of the force receiving plate 45 through the reaction force, and then keeping the mounting plate 31 in a stable posture, avoiding the angle deviation of the sensor caused by slight deviation in the installation operation. At the same time, the fixed connection of the force receiving plate 45 and the connecting ring 43 ensures that the rotation of the force receiving plate 45 can be transmitted to the connecting ring 43 synchronously, laying a foundation for the linkage of the subsequent angle display mechanism 5.
[0039] As a further embodiment of the present scheme, the sensor body 2 is fixedly connected to the top of the mounting plate 31, the inside of the mounting plate 31 is provided with a through hole 32, the inside of the through hole 32 is provided with a bolt 33, the inner wall of the vehicle body mounting part 1 is provided with a threaded hole 34, the outside of the guide rod 54 is fixedly connected with a limiting column 56, and the inside of the dial 57 is provided with a connecting groove 58.
[0040] It should be noted that the through holes 32 are symmetrically distributed in the inside of the mounting plate 31, the bolt 33 is matched with the threaded hole 34, the guide rod 54 is located in the connecting groove 58 inside the dial 57, and the limiting column 56 is rotatably connected to the inner wall of the connecting groove 58. When the mounting plate 31 is connected to the vehicle body mounting part 1, the push plate 35 is in close contact with the force receiving plate 45.
[0041] Further, the core of the structure design of the angle display mechanism 5 is to "convert mechanical rotation into intuitive scale", and the connection relationship and position layout of each component serve the "reading accuracy". The extension rod 51 is fixed outside the stress plate 45, which can synchronously transmit the slight rotation of the stress plate 45 to the rotating plate 52 at the top. The rotating plate 52 is fixedly connected to the bottom of the scale disc 57 at the top, so that the scale disc 57 can rotate synchronously with the rotating plate 52, realizing the accurate transmission of "stress plate 45 rotation-scale disc 57 rotation". The fixed plate 53 is fixedly connected to the outside of the vehicle body mounting part 1, providing stable support for the guide rod 54. The guide rod 54 is not only the rotating shaft of the scale disc 57, but also the limiting column 56 fixed outside the guide rod 54 is embedded in the connecting groove 58 inside the scale disc 57, and the limiting column 56 can rotate in the inner wall of the connecting groove 58. This structure design can not only limit the axial displacement of the scale disc 57 to avoid the scale disc 57 from falling off or deviating, but also reduce the friction resistance when the scale disc 57 rotates, ensuring smooth rotation. In addition, the scale disc 57 is located between the pointer 55 and the fixed plate 53, so that the operator can clearly observe the corresponding relationship between the pointer 55 and the scale disc 57. The pointer 55 is fixed at the top of the tail end of the guide rod 54, and the position is always unchanged, further ensuring the accuracy of the angle reading, realizing the operation closed loop of "real-time observation-accurate adjustment".
[0042] Work flow: First, fix the sensor body 2 on the top of the mounting plate 31 of the mounting mechanism 3, then pass the bolt 33 through the symmetrical distribution of the insertion hole 32 inside the mounting plate 31, and align the threaded hole 34 in the inner wall of the vehicle body mounting part 1 for preliminary connection.
[0043] In this process, the push plate 35 outside the mounting plate 31 will closely adhere to the stress plate 45 of the rotating mechanism 4. The stress plate 45 is movably connected to the connecting ring 43 through the connecting rod 42 inside the fixed seat 41. The torque spring 44 between the connecting rod 42 and the connecting ring 43 will be elastically constrained under the action of the push plate 35, ensuring that the mounting plate 31 maintains a stable posture during adjustment, avoiding angle deviation.
[0044] At the same time, the extension rod 51 fixed outside the stress plate 45 will drive the rotating plate 52 to move synchronously with the slight rotation of the stress plate 45. Since the rotating plate 52 is fixedly connected to the bottom of the scale disc 57 at the top, the scale disc 57 will rotate under the support of the guide rod 54 on the fixed plate 53 outside the vehicle body mounting part 1. The pointer 55 at the tail end of the guide rod 54 is fixed in position, and the operator can directly read the installation angle of the sensor body 2 by pointing to the scale value of the scale disc 57 through the pointer 55, and then accurately adjust the fastening degree of the bolt 33, finally realizing the accurate installation and positioning of the sensor body 2 and the angle calibration. The whole process does not require additional measuring tools, and the operation is continuous and the positioning accuracy is high.
[0045] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
