Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, a kind of light car body skeleton inspection device comprises detection bodies 1 and skeleton 2, and skeleton 2 is fixed on the upper surface of detection bodies 1, forms the assembly with certain Rigidity and strength.Whether detection bodies 1 needs to meet design requirement fully for detection of multiple unit train body window glass adhesive surface by the designing requirement Precision Machining, and skeleton 2 is for increasing the integral rigidity of detection bodies 1 and for operator's holding operation.
The detection bodies 1 preferred ABS material that adopts according to the shape and size of car body window, through accurate cut moulding, is selected the ABS material, can make the weight of detection bodies 1 relatively light.The material of detection bodies 1 also can use high density for wood or metal, and detection bodies 1 preferably adopts aluminium sheet when adopting metal material.The material of skeleton 2 preferably adopts aluminium or aluminium alloy, to important requirement light especially can adopt titanium alloy, be to improve rigidity, skeleton 2 can also adopt carbon steel, but corresponding weight also can increase.
Because the ABS material is influenced by environmental temperature, material line expansion system is larger, the material elastic modulus is little, yielding, and the material of skeleton 2 is metals, and whole cubing is combined by ABS and metal bi-material, because of the linear expansion coefficient of bi-material inconsistent, cause the cubing bulk deformation, Deformation Reasons mainly is to detect the position ABS distortion is large at ambient temperature, thereby produces larger internal stress and make bulk deformation.Be the change of shape that minimizing produces owing to variation of ambient temperature, present embodiment, detection bodies 1 adopts multistage splicing composition, dwindles molding surface size, leaves certain flexible gap 3 between each section, and as shown in Figure 1, detection bodies 1 is divided into three sections in the present embodiment.Flexible gap 3 is so that the minimizing of detection bodies 1 size varies with temperature the line that the brings factor that rises reduces, and stress reduces, and makes detection bodies 1 because the change in size that temperature variation is brought is stable in allowed limits, and then has guaranteed the accuracy of detection of detection bodies 1.
To shown in Figure 5, the cross section of skeleton 2 is L shaped such as Fig. 2, and it can adopt the sheet material bending to form, and also can adopt the section bar excision forming.As shown in Figure 4, be fixedly connected with by a plurality of L shaped web members 4 between skeleton 2 and the detection bodies 1, the both sides of L shaped web member 4 are connected with the skeleton 2 of detection bodies 1 by screw 5 respectively, and fixing means is simple to operation, the restriction of not examined body 1 and skeleton 2 shapes.The common i shaped cross section that forms after detection bodies 1 is connected with skeleton 2, depth of section is increased, and section thickness reduces, and can obtain larger cross sectional moment of inertia with less cross section, when reducing weight, improves the Rigidity and strength of whole cubing.
For guaranteeing skeleton 2 integral rigidities and intensity, many gussets 9 adopt two-way diagonal bar arranged in a crossed manner, increase whole skeleton 2 and stop the ability of reversing.Under torsional load, two main stress of member are Transverse Shear stress and longitudinal shearing stress, two power are combined produce diagonal angle tension and compression stress, and are maximum in 45 degree directions.At 45 degree places, lateral shear stress and longitudinal shear stress offset each other, so become the member of 45 degree substantially not have twisting resistance with respect to the central axis of skeleton 2, make skeleton 2 that higher Rigidity and strength be arranged.
For weight reduction, in the situation that does not affect skeleton 2 integral rigidities, have several circular holes 10 in the neutral axis central area of framework 8 and/or gusset 9, because the neutral axis central area should ring less to bending resistance, to alleviate the overall weight of skeleton 2, be beneficial to operator's operation.
Such as Fig. 1, Fig. 4 and shown in Figure 5, need to be provided with the face that detected body contacts a plurality of cushion blocks 6 for the location in detection bodies 1, comprising the side cushion block of side location and the heelpiece piece of location, base.The purpose that adds cushion block 6 is the contact area that reduces between detection faces and the detected face, and then is conducive to improve accuracy of detection.Cushion block 6 adopts copper cushion block, by the machine work moulding.
As shown in Figure 6, for preventing that dislocation is moved in flexible gap 3 between two working of plastics, corresponding register pin 7 and the pilot hole (not shown) of being provided with is used for the location between the detection bodies 1 of each section, and register pin 7 adopts elastic cylindrical pins, can prevent from vibrating the distortion of the detection bodies 1 that impulsion brings.
In cubing manufacturing process, at first detection bodies 1 is fixed in certain die cavity, make detection bodies 1 keep intrinsic shape, the skeleton 2 that has assembled is fixed together with detection bodies 1 by L shaped web member 4 with screw 5 again.
As mentioned above, given scheme content can derive similar technical scheme in conjunction with the accompanying drawings and embodiments.In every case be the content that does not break away from technical solutions of the utility model,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
