A kind of rear floor frame assembly detects utensil
Technical field
The present invention relates to component of machine surveying instrument field, relate in particular to a kind of rear floor frame assembly and detect utensil.
Background technology
The rear overhang installation place of automobile lower body swing arm---the dimension precision requirement of rear floor frame assembly is higher, bad if precision is controlled, and can cause lower body swing arm assembling difficulty, affects car load four-wheel precision.As shown in Figure 1, in general, because described rear floor frame assembly 1 is often out of shape, therefore particularly important to detection herein, Detection of content to rear floor frame assembly 1 comprises: the distance between the left back stiffening plate 11 of Rear secondary frame for vehicle and left trailing link installing plate 12, the aperture in the first hole 111 of offering on the left back stiffening plate 11 of Rear secondary frame for vehicle, the aperture in the second hole 121 of offering on left trailing link installing plate 12, distance between the right back stiffening plate 14 of right trailing link installing plate 13 and Rear secondary frame for vehicle, the aperture in the 3rd hole 131 of offering on right trailing link installing plate 13, the aperture in the 4th hole 141 of offering on the right back stiffening plate 14 of Rear secondary frame for vehicle, right alignment between the first hole 111 and the second hole 121, right alignment between the 3rd hole 131 and the 4th hole 141, and the distance between left trailing link installing plate 12 and right trailing link installing plate 13.Wherein, the left back stiffening plate 11 of described Rear secondary frame for vehicle and left trailing link installing plate 12 are all positioned at the left side of described rear floor frame assembly 1, described right trailing link installing plate 13 and the right back stiffening plate 14 of Rear secondary frame for vehicle are all positioned at the right side of described rear floor frame assembly 1, and the left back stiffening plate 11 of described Rear secondary frame for vehicle, left trailing link installing plate 12, right trailing link installing plate 13 and the right back stiffening plate 14 of Rear secondary frame for vehicle are arranged from left to right in turn.
In prior art, conventionally use the distance between the left back stiffening plate 11 of vernier caliper measurement Rear secondary frame for vehicle and left trailing link installing plate 12, distance between the right back stiffening plate 14 of right trailing link installing plate 13 and Rear secondary frame for vehicle, and the aperture in 4 holes, and distance between left trailing link installing plate 12 and right trailing link installing plate 13 is generally by measuring the lower body swing arm actual mode being placed between left trailing link installing plate 12 and right trailing link installing plate 13 in kind, right alignment between the first hole 111 and the second hole 121, and the 3rd right alignment between hole 131 and the 4th hole 141 generally by axiality measuring apparatus, measure.
The defect of prior art is: after completing, the detection of floor frame assembly need to be used vernier caliper, lower body swing arm material object and 3 objects of axiality measuring apparatus, detect complex procedures, expend man-hour (the therefore general mode that adopts sampling observation), detection efficiency is low, and, because the volume and weight of lower body swing arm material object is large, working strength is large, depends merely on one and detects workman and complete and have any problem.

Detection method below in conjunction with Fig. 1 and Fig. 2 application detection utensil 2 of the present invention is:
Step 1: described detection utensil 2 is placed in to rear floor frame assembly 1 place, and according to the first test section 27 in left side, the second test section 28 is put in the mode on right side, make the left back stiffening plate 11 of Rear secondary frame for vehicle and the left trailing link installing plate 12 of the first test section 27 corresponding rear floor frame assemblies 1, make right trailing link installing plate 13 and the right back stiffening plate 14 of Rear secondary frame for vehicle of the second test section 28 corresponding rear floor frame assemblies 1;
Step 2: the first sleeve 241 of the first test section 27 is inserted between the left back stiffening plate 11 of Rear secondary frame for vehicle and left trailing link installing plate 12, and the second sleeve 242 of the second test section 28 is inserted between right trailing link installing plate 13 and the right back stiffening plate 14 of Rear secondary frame for vehicle, now, only have in the situation of the first sleeve 241 and the second successfully insertion of 242 whiles of sleeve, just carrying out following testing process (is step 3), otherwise determines that current detected rear floor frame assembly 1 is defective;
Step 3: the shank of the first register pin 251 is run through to described the first hole 111 in turn, the first sleeve 241 and the second hole 121, the shank of the second register pin 252 is run through in turn to described the 4th hole 141 simultaneously, the second sleeve 242 and the 3rd hole 131, now, when meeting following condition simultaneously, can determine that current detected rear floor frame assembly 1 is qualified, otherwise determine that current detected rear floor frame assembly 1 is defective: (the shank of (1) first register pin 251 successfully completes above-mentioned penetrating action, run through in turn described the first hole 111, the first sleeve 241 and the second hole 121), the shank of (2) second rationed marketings successfully completes above-mentioned penetrating action (that is, running through in turn described the 4th hole 141, the second sleeve 242 and the 3rd hole 131), (3) both ends of the surface of described the first sleeve 241 are against respectively on the left back stiffening plate 11 of Rear secondary frame for vehicle and left trailing link installing plate 12, (4) both ends of the surface of described the second sleeve 242 are against respectively on right trailing link installing plate 13 and the right back stiffening plate 14 of Rear secondary frame for vehicle, (5) gap between the shank of described the first register pin 251 and the first hole 111 is little (judge by the experience with slip-stick artist during concrete operations, identical below), gap between the shank of described the first register pin 251 and the second hole 121 is little, gap between the shank of described the second register pin 252 and the 3rd hole 131 is little, and the gap between the shank of described the second register pin 252 and the 4th hole 141 is little.
What deserves to be explained is, in above-mentioned steps 3, satisfy condition (1) and (2) mean: the distance between the right alignment between the right alignment between the first hole 111 and the second hole 121, the 3rd hole 131 and the 4th hole 141, the second hole 121 and the 4th hole 141 and the position of offering in 4 holes all meet the demands.Satisfy condition (3) and (4) mean: the distance between the distance between the left back stiffening plate 11 of Rear secondary frame for vehicle and left trailing link installing plate 12 and right trailing link installing plate 13 and the right back stiffening plate 14 of Rear secondary frame for vehicle all meets the demands, and can determine 4 plates all distortion (at least can determine that the position contacting with sleeve on plate is not out of shape).Satisfy condition (5) mean: the aperture in the 4th hole 141 of offering on the aperture in the 3rd hole 131 of offering on the aperture in the second hole 121 of offering on the aperture in the first hole 111 of offering on the left back stiffening plate 11 of Rear secondary frame for vehicle, left trailing link installing plate 12, right trailing link installing plate 13 and the right back stiffening plate 14 of Rear secondary frame for vehicle all meets the demands.
Embodiment shown in above foundation is graphic describes structure of the present invention, feature and action effect in detail; the foregoing is only preferred embodiment of the present invention; but the present invention does not limit practical range with shown in drawing; every change of doing according to conception of the present invention; or be revised as the equivalent embodiment of equivalent variations; when not exceeding yet instructions and illustrating contain spiritual, all should be in protection scope of the present invention.
