Embodiment

To bumper energy absorbent block cubing shown in Figure 9, the bottom is a block casting iron base 1 as Fig. 1, and base 1 back is provided with the reinforcement of " X " type or " rice " font, to prevent the distortion after the long-term use; 2 carrying handles 12 respectively are equipped with in both sides on base 1 length direction, its objective is to the handled easily personnel to carry.1 four corners of base are provided with machining benchmark point/datum hole 11, and the reference point coordinate is marked on the next door.Base 1 front is marked with red hundred lattice scale marks, and is clear so that base is divided.Will varnish after finally machining in base 1 surface, guarantee the bright and clean of susceptor surface.The length and width of base are of a size of 1400mm*410mm, highly are 85mm.It is comparatively suitable that the basic size of base generally is controlled at about 1.2 times of institute's testing product size.If the excessive waste that may cause material, and the time grown and may cause distortion.Suggestion to the accuracy requirement of base processing be controlled at≤scope of 0.10mm in.

Mainly based on 3 sectional type simulated

blocks

21,22 and 23, each simulated block is fixed on above the base by the register pin of bottom in base 1 top.The concrete quantity of simulated block can specifically design according to the difference of product structure, selects relatively more intensive or can select in non-key position relatively to evacuate.The main effect of simulated block is to be used for the installation environment of simulated automotive bumper and energy absorbent block, be used for placing and fixing energy absorbent block 4, each simulated block upper end forms a curved surfaces, according to the desired rigging position difference of different products, when design, detect requirement and determine that rational A, B, C benchmark come the degree of freedom of limits product 6 directions in the space according to the profile tolerance tolerance.Can keep stable and unified detected state after making product be placed on this cubing; Only in this way could effectively improve accuracy of detection.Requirement on machining accuracy for simulated block preferably is controlled at≤scope of 0.05mm.

Make 5 check-out consoles 3 above simulated

block

21,22 and 23, the principle that the quantity of check-out console 3 and distribution and simulated block distribute is basic identical; According to the requirement of the concrete structure of product, the distribution of arranging density.As no specific (special) requirements, 150mm～200mm can be selected in the interval between the check-out console in principle, and entire product evenly distributes.Check-out console 3 is across the surface of product, adopts monolateral flipped form; As shown in the figure, on the base 1 of both sides, energy absorbent block 4 front and back, be respectively equipped with check-out

console pedestal

33a and 33b be used for taking by and fixed test plate 3, wherein the position of the check-out console slot piece 31 on the check-out console pedestal 33a of energy absorbent block 4 one sides is provided with check-out console rotating shaft 32, pivot around this rotating shaft to satisfy check-out console 3, realize the requirement of monolateral upset; Can certainly adopt the form of plug.Avoid check-out console double swerve gap when requiring check-out console to insert as far as possible, guarantee accuracy of detection.Must carve the acquiescence gap between bright check-out console and the product on the check-out console 3, generally adopt the 5mm gap to be benefit; Can carry out reading so easily and guarantee the accurate and stable of reading.Check-out console 3 keeps normal direction vertical with the detection faces of its installation position product.Evenly detect the edge of a knife and remain on unified direction at the thick end of all check-out consoles; The machining precision of check-out console preferably is controlled at≤scope of 0.15mm.

Two active grabs 41 with movable presser feet are installed on energy absorbent block 4 both sides in addition, to be used for finally compressing product; The time spent does not open, and depresses during use.The rubber material of active grab presser feet head softness can avoid damaging the surface of product.

Aluminum is also adopted in the processing of simulated block of the present utility model and check-out console as far as possible, though strengthened the weight of whole cubing, can effectively improve the precision of detection, and long-term the use is not easy distortion.

This cubing overall structure is simple and practical, and stability and safety, has positive effect.
