Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The device can inspect the parallelism of the lateral opening ends of the flat forks, the total length of the flat forks and the width of the motor installation, and the inspection is convenient and efficient.
[0016] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] When in use, the parallelism pin fixing rod 6 is passed through the axial hole of the flat fork 9 and installed on the mounting holes 5 at both ends of the fixing frame 4. The inspection plate 3 is driven to translate by the linear drive mechanism so that the end face of the open end of the flat fork 9 abuts against the plate surface of the inspection plate 3. If the two end faces of the open end of the flat fork 9 are tightly fitted with the inspection plate 3, it indicates that the parallelism of the horizontal open end of the flat fork 9 meets the requirements. Since the axis of the mounting hole 5 is parallel to the inspection platform 1 and the inspection plate 3, the distance between the axis of the mounting hole 5 and the inspection plate 3 is the total length of the flat fork 9. The total length here refers to the length from the axis of the axial hole of the flat fork 9 to the end face of the open end. The total length of the flat fork 9 can be easily measured by the total length measuring ruler 7, and the motor installation width size of the electric vehicle flat fork 9 can be easily measured by the motor installation width measuring ruler 8, so as to check whether its size meets the requirements and improve the inspection efficiency. Since the inspection plate 3 can translate, the device can be applied to the inspection of different types of flat forks.

The lead screw 10 is rotatably connected to the inspection platform 1, one end of the lead screw 10 is connected to the hand wheel 12, the lead screw nut block 11 is threadedly connected to the lead screw 10, and a slider 13 is slidably connected to the guide rail 2. The slider 13 is fixed to the inspection plate 3 and fixedly connected to the lead screw nut block 11. The hand wheel 10 drives the lead screw 10 to rotate, and the rotation of the lead screw 10 drives the lead screw nut block 11, the slider 13 and the inspection plate 3 to translate, which has a simple structure and is easy to operate.
[0020] In this embodiment, a guide rod 14 is fixedly provided on the inspection platform 1, and the guide rod 14 is parallel to the lead screw 10.
