Description
Technical field
The utility model relates to Machining Technology field, is specially a kind of assembled panorama bent axle calibrating device.
Background technology
Bent axle is the strength member of engine.Bent axle out-of-shape, the six engine crankshaft connecting rods turned are that 120 ° of space phase angles are uniformly distributed, and phase deviation requires strict, and main shaft, connecting rod neck dimensional accuracy are high, also have many places thrust surface size, need to carry out online Comprehensive Correlation measurement.
In existing integral shaft calibrating device, the dimensional tolerence of king journal and connecting rod neck, and the shaped position tolerance of main shaft and connecting rod all will control 0.02, due to bent axle out-of-shape, calibrating device single-piece production, stamp work or precision castings can not be adopted, and calibrating device total length is more than 720, after heat-treatment quenching, heat treatment deformation is large, calibrating device dimensional accuracy cannot reach, and is difficult to realize measurement of comparison.
Utility model content
Therefore, in order to overcome the deficiency that prior art exists, the utility model provides a kind of by simple and practical connected mode, can realize the assembled panorama bent axle calibrating device that bent axle complete contrast measures.
The utility model assembled panorama bent axle calibrating device comprises base plate, thrust plate and multiple first support, second support and the 3rd support, described thrust plate, first support, second support and the 3rd support are all arranged on base plate by positioning key, outermost two the second supports are between two the first supports of inner side, described 3rd support is between the second adjacent support, described first support is provided with king journal and connecting rod neck simultaneously, described second support is provided with king journal, described 3rd support is provided with connecting rod neck, the height of described 3rd support is greater than the height of the second support, the axis of all king journals is all located along the same line.
The utility model adopts the design of assembled calibrating device, calibrating device mechanism is simple, easy ensures calibrating device crudy, guarantee calibrating device dimensional accuracy, do not increase energy consumption, starting material are simple, operation is clear and easy to process, meet the request for utilization that Comprehensive Correlation is measured.
After reading the detailed description of the utility model embodiment by reference to the accompanying drawings, other features of the present utility model and advantage will become clearly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail, wherein:

Embodiment
Below in conjunction with accompanying drawing and embodiment of the present utility model, the utility model assembled panorama bent axle calibrating device is made the following instructions.
Embodiment: a kind of assembled panorama bent axle calibrating device, comprise base plate 3, thrust plate 4 and multiple first support 2, second support 5 and the 3rd support 8, described thrust plate 4, first support 2, second support 5 and the 3rd support 8 are all arranged on base plate 3 by positioning key 6, outermost two the second supports 5 are between two the first supports 2 of inner side, described 3rd support 8 is between the second adjacent support 5, described first support 2 is provided with king journal 1 and connecting rod neck 7 simultaneously, described second support 5 is provided with king journal 1, described 3rd support 8 is provided with connecting rod neck 7, the height of described 3rd support 8 is greater than the height of the second support 5, the axis of all king journals 1 is all located along the same line, described base plate 3 is provided with the connecting hole 3a for installing the thrust plate 4 and mounting groove 3b for installing positioning key 6.
First support 2, second support 5 and the arrangement position of the 3rd support 8 on base plate 3 are determined by thrust plate 4, with thrust surface 4a for benchmark is in order to left and right launching respectively.First the coordinate figure of bent axle X, Y is calculated.The coordinate figure of X is for determining connecting rod neck 7 and the distance and position of king journal 1 axial line in X-direction.By the first support 2, second support 5 and the 3rd support 8, the arrangement position on base plate 3 realizes, and can also be realized by the connecting hole K position the first support 2, second support 5 and the 3rd support 8 being used for install king journal or connecting rod neck.Y-coordinate is used for determining king journal 1 center and connecting rod neck 7 centre distance position, realizes by the center of the first support 2, second support 5 and the 3rd support 8 is high.After the coordinate of bent axle has decomposed, on base plate 3, make connecting hole 3a according to coordinate figure, the contact position required according to gauge head is opened dead slot 3b and is installed positioning key 6, is used for ensureing the right alignment of king journal 1, makes the axis of each king journal 1 on the same line.Above-mentioned parts install according to relevant position by base plate 3, and is fastenedly connected with base plate 3.Adjust at boring machine, reach the precision required by calibrating device.Its testing process is as follows: be first placed on monitor station by calibrating device, thrust plate 4 positioning datum, and gauge head runs and puts in place under the control of electrical appliance part, image data after touching calibrating device---reset.Change bent axle to be checked, support--location--and detect, after image data, draw testing result, qualified at margin tolerance inside crankshaft, realize the whole online full-scale measurement of comparison of bent axle.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
