Detailed description of the invention
1-4 describes embodiment of the present utility model below in conjunction with the accompanying drawings.
For detecting the profile cubing of crankshaft balance weight part, as illustrated in fig. 1 and 2, there is identical profile measurement model body 2 corresponding with crankshaft balance weight part 1 appearance profile requirement, concrete, model profile circular arc 23 radius of both sides, described profile measurement model body 2 bottom is identical with External Shape Machining Arc 12 radius of both sides, crankshaft balance weight part 1 bottom, distance between center of arc 26 and the model upper surface 24 of described model profile circular arc 23 is equal to the distance between Machining Arc center 14 and the part upper surface 11 of External Shape Machining Arc 12, distance between described model upper surface 24 and model shoulder end face 25 is equal to the distance between part upper surface 11 and part shoulder end face 13, auxiliary operation hole 22 is set in the middle of described profile measurement model body 2.
Model upper surface 24 and centre, model lower surface 28 on described profile measurement model body 2 are equipped with monolateral double V-groove 21, concrete, as shown in Figure 3, described monolateral double V-groove 21 includes straight flange 211 and hypotenuse 212, distance between described straight flange 211 and model centrage 27 is 0.3mm, angle between described straight flange 211 and hypotenuse 212 is 45 degree, described straight flange 211 and hypotenuse 212 bottom junctions are by fillet 213 transition, described fillet 213 radius is 2mm, the degree of depth of described monolateral double V-groove 21 is 20mm, described monolateral double V-groove 21 is provided with groove, facilitate centering, avoid determining back and forth Central of the parts, improve accuracy in detection and detection efficiency.
