Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
In the practical stamping forming process of the automobile body beam parts, the most common problem of the parts is that the flange edges are easy to rebound and warp, and because the existing detection standard is generally selected on the flange surface of the parts, the out-of-tolerance of the flange surface is not objectively reflected in the detection data, so that the whole height of the parts is lowered, and the rebound value of the side wall surface of the parts is inaccurate. If the automobile part stamping die is modified and debugged according to the detection data in the state, the flange surface is used as a reference surface to be continuously adjusted, so that the modification difficulty is increased. Meanwhile, the measured value of the part does not reflect the state that the Z-direction height is low, and interference phenomenon can be generated with other parts in the actual assembly process.
In order to solve the problems, the utility model provides a stamping debugging and detecting device for a vehicle body beam part. As shown in fig. 1 to 3, the device for detecting stamping debugging of a vehicle body beam part mainly comprises: part one 1, part two 2, 2 locating pins and 4 RPS (REFERENCE POINT SYSTEM ) support blocks 5; wherein the 2 locating pins are a first locating pin 3 and a second locating pin 4 respectively.
The first part 1 is a concave part, flanges 101 are arranged on two side edges of the concave part, three mounting holes are formed in the upper surface of the concave part, and the three mounting holes are a first positioning hole 102, a second middle mounting hole 103 and a second positioning hole 104 respectively.
As shown in fig. 3, the second part 2 is a male part, the upper surface of the male part is provided with three mounting holes, namely a third positioning hole 201, a second middle mounting hole 202 and a fourth positioning hole 203, which are arranged in one-to-one correspondence with the three mounting holes on the upper surface of the first part 1, and the positions of the first positioning hole 102, the second middle mounting hole 103, the second positioning hole 104, the third positioning hole 201, the second middle mounting hole 202 and the fourth positioning hole 203 are all critical control dimensions in the debugging and detecting process. The two sides of the lower end of the second part 2 are provided with steps 204. The first and second positioning pins 3 and 4 are installed in the third and fourth positioning holes 201 and 203, respectively.
Wherein, the structure, the size, the material and the like of the 4 RPS (REFERENCE POINT SYSTEM ) support blocks 5 are identical.
The positional connection relationship among the first part 1, the second part 2, the 2 positioning pins and the 4 RPS support blocks 5 is as follows: firstly, 4 RPS supporting blocks 5 are respectively arranged on the upper surface of a part two 2, wherein 2 RPS supporting blocks 5 are symmetrically fixed on two sides of the front end of a third positioning hole 201 on the upper surface of the part two 2, the other 2 RPS supporting blocks 5 are symmetrically fixed on two sides of the rear end of a fourth positioning hole 203 on the upper surface of the part two 2, then the part one 1 is arranged on the part two 2, a first positioning hole 102, a second middle mounting hole 103 and a second positioning hole 104 on the part one 1 are respectively in one-to-one correspondence with a third positioning hole 201, a second middle mounting hole 202 and a fourth positioning hole 203 on the part two 2, at the moment, the lower surface of the upper end of the part one 1 is supported by the 4 RPS supporting blocks 5 on the part two 2, then the positions of the part one 1 and the part two 2 are fixed by adjusting a first positioning pin 3 and a second positioning pin 4, and a flange 101 of the part one 1 is positioned on a step 204 of the part two 2, as shown in FIG. 2. The surface between the upper end of the first part 1 and the upper end of the second part 2 is a third mounting surface c, the surface between the side wall of the first part 1 and the side wall of the second part 2 is a second mounting surface b, the surface between the flange 101 at the lower end of the first part 1 and the steps 204 at two sides of the lower end of the second part 2 is a first mounting surface a, and the precision of the first mounting surface a, the second mounting surface b and the third mounting surface c is the critical control size in the debugging and detecting process. After the installation is completed, the first positioning pin 3 can restrict the X-direction freedom degree, and the second positioning pin 4 can restrict the Y-direction freedom degree; the 4 RPS support blocks 5 are each used to constrain the Z-direction degrees of freedom.
The utility model discloses a stamping debugging detection device for a vehicle body beam part, which introduces a positioning concept of a debugging reference and establishes the debugging detection device based on the debugging reference. The utility model mainly follows three basic principles of measurement and positioning: an N-2-1 positioning principle, a coordinate parallel principle and a reference consistency principle. According to the positioning principle of N-2-1, the converted positioning surface is determined by the direction of the largest projection surface with the minimum deformation of the part, and more than 3 positioning references are arranged, so that the influence of rigidity difference and gravity can be reduced. As shown in fig. 1, 4 RPS supporting blocks 5 are arranged on the third mounting surface c, and the upper surfaces of the 4 RPS supporting blocks 5 are all positioning reference surfaces e, as shown in fig. 3, and meanwhile, the first positioning hole 102 and the second positioning hole 104 on the first part 1 are kept consistent with the third positioning hole 201 and the fourth positioning hole 203 on the second part 2 respectively; at this time, X, Y-direction constraint is not changed, the Z-direction constraint position moves in parallel, and the constraint function is effective.
Further, from GD & T requirements of the parts, it can be found that the accuracy requirement of the first mounting surface a is ±0.3mm, the accuracy requirement of the third mounting surface c is ±0.5mm, and it is necessary to give the accuracy requirement of the first mounting surface a to the third mounting surface c. Because the influence of the rebound warping of the flange edge on the first mounting surface a is larger than that of the third mounting surface c, the third mounting surface c has better flatness, and the third mounting surface c is used as a debugging reference, so that errors are not amplified. The debugging detection device established by the debugging reference avoids the interference of the rebound of the part on the precision measurement, can acquire the real rebound data of the side wall and the flange of the part, and is beneficial to quickly making a precision rectifying strategy on the molded surface of the part of the die.
