The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.
[0017] See also Figures 1 to 3 The utility model provides a full-element dimension inspection device for the mounting position of a motorcycle engine, comprising a mounting frame 1, a mounting plate 2, a mounting piece, a positioning frame, two first through-pins 3, two second through-pins 4 and two third through-pins 5, wherein the mounting plate 2 is fixedly connected to the mounting frame 1 and is located at one end of the mounting frame 1, the mounting piece is fixedly connected to the mounting frame 1 and is located on one side of the mounting frame 1, the two first through-pins 3 are threadedly connected to the mounting plate 2 and pass through the mounting plate 2, the two second through-pins 4 are bolted to the mounting piece and pass through the mounting piece, the two third through-pins 5 are bolted to the mounting frame 1 and pass through the mounting frame 1, the third through-pin 5 is arranged on a side of the mounting frame 1 away from the second through-pin 4, and the positioning frame is sleeved on the surfaces of the first through-pin 3, the second through-pin 4 and the third through-pin 5.
[0018] In this embodiment, the first through pin 3 , the second through pin 4 and the third through pin 5 are installation detection points, which are directly involved in the installation of the generator.
[0019] Furthermore, the positioning frame includes an upper bracket 6, a main body 7, a lower bracket 8, a fourth through pin 9 and a fifth through pin 10. The upper bracket 6 is sleeved on the surfaces of the two first through pins 3, and the lower bracket 8 is sleeved on the surfaces of the two third through pins 5. The fourth through pin 9 is bolted to the upper bracket 6 and is located through the upper bracket 6. The fifth through pin 10 is rotatably connected to the lower bracket 8 and passes through the lower bracket 8. The main body 7 is sleeved on the third through pin 5, the fourth through pin 9 and the fifth through pin 10.
[0020] In this embodiment, the main body 7 is the base of the entire inspection fixture, the mounting matrix of other components, and the most important component that determines the accuracy of the entire inspection and manufacturing. The XY direction accuracy requirement is ±0.02. In order to reduce weight and ensure rigidity, the main body 7 is made of aviation-grade LY12 hard aluminum material. The upper bracket 6 and the lower bracket 8 are components that simulate the engine mounting bracket. The position and size of their mounting points are designed to be 1:1 with the mounting bracket to ensure complete restoration of their position and function. The first through pin 3, the second through pin 4, the third through pin 5, the fourth through pin and the fifth through pin are the mounting points of the upper bracket 6, the lower bracket 8 and the generator, corresponding to the position of the direct mounting point of the engine or bracket on the vehicle frame.
[0021] Furthermore, the motorcycle engine installation position full-element dimension inspection device also includes a rotating shaft 11, which is bolted to the lower bracket 8 and passes through the lower bracket 8 and the body 7.
[0022] In this embodiment, the rotating shaft 11 is a reference point of the lower bracket 8 , thereby improving the accuracy of detection.

[0026] In this embodiment, the reference plate 13 is a process component provided to compensate for the poor machinability of the main body 7. Since the surface grinding machinability of LY12 hard aluminum is poor, the main body 7 must serve as the Z-direction machining reference of the entire inspection fixture, and also as an inspection reference for the manufacturing accuracy of the inspection fixture. Therefore, 5mm high-quality carbon steel materials with excellent grinding performance are designed on both surfaces of the main body 7. The reference plate 13 serves as a machining reference to ensure the Z-direction accuracy, and also serves as a detection reference for the Z-direction manufacturing accuracy of the inspection fixture.
