Embodiment one
The process flow diagram of the accessory size detection method that Fig. 3 provides for the embodiment of the invention one.As shown in Figure 3, the accessory size detection method of present embodiment comprises:
Step 301 is positioned over part to be detected on the part cubing, with the part cubing part to be detected is carried out initial detecting, obtains the physical size that can detect the position on the part to be detected;
Wherein, can detect the position refers to use the part cubing of having developed or uses simple part cubing to measure position on the part to be detected of its size.Rectify and improve part cubing (for example increase and detect loose piece) or need to again develop the position that the new parts cubing just can be finished measurement for needs, be referred to as in embodiments of the present invention to detect the position.For example: in Fig. 2, it is that the top line of a-face is poor that the part cubing can be measured the flange face, is depicted as example with Fig. 1 E, can to detect top line poor with the horizontal line 16a maintenance level of dissecing structure 16 tops by detecting cutting line 21 top horizontal line 21a; But because the flange face is positioned at the side, but can't measure the size of whole flange face, therefore, the flange face belongs to that present embodiment is described a kind ofly can not to detect the position; Again for example: have coupling with the part overlap joint along the section of B-B line, D-D line among Fig. 2, this structure can't detect with developing the part cubing, belongs to also that present embodiment is described a kind ofly can not to detect the position; Again for example: the C-C line is depicted as the new critical surfaces of finding among Fig. 2 in vehicle body trial assembly process, because the part cubing develops, this critical surfaces can't be detected, and then this critical surfaces belongs to also that present embodiment is described a kind ofly can not to detect the position.The position detected that namely the present invention relates to and can not detect the position for the part cubing.
Step 301 specifically comprises: part to be detected is positioned on the cubing detection faces of part cubing, shown in Figure 1A; Main pilot hole and negative pilot hole according to the part cubing position part to be detected, shown in Fig. 1 C; Use the detection loose piece on the part cubing that the position detected on the part to be detected is detected, read the physical size that can detect the position according to the size that indicates on the part cubing.Wherein, the position detected of present embodiment can be other positions except shown in B-B line, C-C line and the D-D line among Fig. 2.
Step 302 is placed into the part cubing that carries part to be detected on the CMM measuring instrument platform, and part cubing and CMM measuring instrument platform are carried out position correction;
Wherein, owing to part to be detected is had good positioning with the part cubing, and this positional accuracy is higher; Therefore, after utilizing the part cubing to finish initial detecting to part to be detected, can directly the part cubing that carries part to be detected be placed directly on the CMM measuring instrument platform, to use the CMM measuring instrument part to be detected further be detected, namely step 303 is described.
Wherein, before execution in step 303, need to carry out position correction to part cubing and CMM measuring instrument.Concrete, by the reference block on the part cubing (shown in Figure 1A), to the part cubing with CMM measuring instrument platform carries out centering and to coordinate, to determine the three-dimensional coordinate starting point of CMM measuring instrument platform, usually be referred to as zero point.For example: determine to be at coordinate zero point (10,10,0).
Step 303 uses the CMM measuring instrument that part to be detected is compensated detection, obtains the physical size that can not detect the position on the part to be detected.
Concrete, after the zero point of determining the CMM measuring instrument, can not detect the position by 30 pairs of the detecting pens of CMM measuring instrument and carry out dimensional measurement.Wherein, Fig. 4 goes out the state of detecting pen 30 measuring process from dissecing structural representation.Concrete, detecting pen 30 carries out point-to-point measurement along the cutting line that can not detect the position 21 on the part to be detected, obtains a plurality of coordinate figures; The coordinate figure that obtains is admitted to the software processing module of CMM measuring instrument, for software processing module coordinate figure is processed, and obtains the physical size that can not detect the position.Wherein, the structure of dissecing that can not detect the position shown in Figure 4 is the structure of dissecing along Fig. 1 C or A-A line shown in Figure 2, but is not limited to this.Wherein, the software processing module of CMM measuring instrument can be exported the physical size that can not detect the position, understands the dimensional accuracy of part to be detected for the staff.
The accessory size detection method of present embodiment at first adopts the part cubing that part is carried out initial detecting, to obtain the size that can detect the position; Then, adopt the CMM measuring instrument that part is replenished detection, the size at the position that can't detect with detection part cubing.By this technical scheme, can under the condition of developing relatively simple part cubing, realize the detection to baroque accessory size, and then guarantee part the cubing convenience that uses and the requirement that reduces the manufacturing accuracy of part cubing; By this technical scheme, can also develop the part cubing or again not develop in the situation of new part cubing not rectifying and improving, finish the detection to the accessory size of structural change, reduce testing cost and sense cycle.
Further, compare with the technical scheme of using the CMM measuring instrument to detect separately in the prior art, technical solution of the present invention positions part to be detected by the part cubing, and its location is fast, accuracy is high, has overcome the poor defective of existing CMM measuring instrument positional accuracy; And overcome when causing greatly using the CMM measuring instrument to be measured because of the measurement data amount long, inefficient problem detection time, improved detection efficiency.
