Problems solved by technology
[0004] The defect of the existing technology is that: to complete the detection of the rear floor frame assembly, three objects need to be used: a vernier caliper, a real object of the swing arm of the lower vehicle body, and a coaxiality measuring instrument. , the detection efficiency is low, and, due to the large volume and weight of the lower vehicle body swing arm, the work intensity is high, and it is difficult to complete it by only one detection worker

Embodiment Construction
[0038] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.
[0039] Reference Figure 2 to Figure 4 The rear floor frame assembly testing instrument 2 includes a rod body 21, a first positioning pin 251, a second positioning pin 252, a first detection portion 27 and a second detection portion 28. The installation positions and sizes of the various components of the detection appliance 2 are set with reference to the standard rear floor frame assembly 1.
[0040] Specifically, the first detection portion 27 includes a first sleeve 241 installed at the left end of th...

The invention discloses a rear floor frame assembly detection instrument. A first detection part comprises a first sleeve installed on the first side face of a rod, and the inner diameter of the first sleeve, the diameter of a first positioning pin, the diameter of a first hole formed in a left rear reinforcing plate on a rear auxiliary frame and the diameter of a second hole formed in a left longitudinal pushing rod installation plate are the same. A second detection part comprises a second sleeve installed on the first side face, and the inner diameter of the second sleeve, the diameter of a second positioning pin, the diameter of a third hole formed in a right longitudinal pushing rod installation plate and the diameter of a fourth hole formed in a right rear reinforcing plate on the rear auxiliary frame are the same. The length of the first sleeve is equal to the distance between the center of the first hole and the center of the second hole, and the length of the second sleeve is equal to the distance between the center of the third hole and the center of the fourth hole. When the detection instrument is assembled on a rear floor frame assembly, the first positioning pin can penetrate through the first hole, the first sleeve and the second hole in sequence, and the second positioning pin can penetrate through the fourth hole, the second sleeve and the third hole in sequence.
Description
Technical field [0001] The invention relates to the field of measuring instruments for mechanical parts, in particular to a detection instrument for a rear floor frame assembly. Background technique [0002] The rear suspension installation location of the lower car body swing arm—the rear floor frame assembly requires a relatively high dimensional accuracy. If the accuracy is not well controlled, it will cause difficulty in the assembly of the lower car body swing arm and affect the accuracy of the four wheels of the vehicle. Such as figure 1 As shown, generally speaking, since the rear floor frame assembly 1 is often deformed, the inspection here is particularly important. The inspection contents of the rear floor frame assembly 1 include: the rear sub-frame left rear reinforcement plate 11 and The distance between the left longitudinal thrust rod mounting plate 12, the aperture of the first hole 111 opened on the left rear reinforcement plate 11 of the rear subframe, the apert...
