Bent axle is the most important parts of the multiple mechanical loads such as engine Bending, torsion, torsional oscillation and vertical transverse vibration.The quality of bent axle quality directly affects the reliability of engine.Its major control size comprises: diameter, the cylindricity of main bearing journal and rod journal, beat and turning radius, each axial dimension etc.These sizes directly affect assembly precision, exercise performance, serviceable life of crankshaft rod assembly etc.Therefore, most important to the control of these sizes and form and position tolerance.The inspection of bent axle adopts appliance special for detecting aborning mostly, but exemplar adopts three-dimensional to detect, and so not only can reduce the investment of appliance special for detecting but also convenient, flexible.Bent axle is in the time that three-dimensional detects at present, just simply part is lain on the worktable of three-coordinates measuring machine, because of the singularity of crankshaft part shape, can not steadily locate, in measuring process, part can produce slight swing, and this can affect measuring accuracy, simultaneously, because bent axle and workbench spacing are little, gauge head cannot carry out complete adopting a little to axle journal, affects measuring accuracy.And, because without accurately locating, will re-establish coordinate system before each parts measurement, extend Measuring Time, inefficiency.Chinese patent Granted publication number: CN202582895U, Granted publication day: 2012.12.05, discloses a kind of bent axle pick-up unit, comprises pair of brackets, and support top is provided with dial gauge, and dial gauge is fixedly mounted on fixed mount.This device is detected to bent axle for three-dimensional, because of unfixing between two supports, need the position between adjusting pole, each parts measurement front position can be different, cause will re-establishing coordinate system before each parts measurement, extended Measuring Time, inefficiency, labour intensity is high.
Utility model content
Problem to be solved in the utility model is, prior art is in the time that three-dimensional detects bent axle, and part can not steadily be located, gauge head cannot carry out complete adopting a little to axle journal, affects measuring accuracy, before each parts measurement, will re-establish coordinate system, extend Measuring Time, inefficiency, the utility model provides a kind of bent axle Bracket for Inspection, in the time that three-dimensional detects bent axle, part steady positioning, measuring accuracy is high, can realize automatic batch detection, has improved and has measured efficiency and reduce surveyor's labour intensity.
The purpose of this utility model is achieved through the following technical solutions.A kind of bent axle Bracket for Inspection, comprise two pedestals that are oppositely arranged, pedestal upside is respectively provided with respectively a V-block, V-block can move up and down at pedestal upside, the downside of described V-block is provided with joint pin, the lower end of joint pin is connected with pedestal upside, is provided with connecting link between pedestal, and pedestal can move along connecting link.When three-dimensional detects bent axle, this support is placed on worktable, according to the position of two pedestals of length adjustment of bent axle, then the axle journal of crankshaft two end is placed in respectively on two V-blocks, the height of adjusting V-block according to the size of two ends axle journal, makes two ends axle journal be positioned at same level position.This support is applicable to the bent axle of different model specification, installation, easy to adjust quick, and highly versatile, has improved work efficiency.Support provides sufficient measurement space to gauge head after bent axle is supported, and has guaranteed that each axle journal can be adopted a little in peripheral direction, part steady positioning, and measuring accuracy is high, has improved the accuracy of measurement result.After support is arranged on worktable, for the bent axle of same model specification, position when crank shaft measurement is definite, does not need to re-establish coordinate system before each parts measurement, can realize automatic batch detection, has improved and has measured efficiency and reduce surveyor's labour intensity.
As preferably, the upper end of described joint pin is cylinder, lower end is provided with screw thread, centre is provided with the columniform back-up block of protrusion, the downside of V-block is provided with the first through hole, the first through hole is smooth cylindrical hole, the cylinder of joint pin upper end is located in the first through hole, joint pin upper end coordinates with the first via clearance, the degree of depth of the first through hole is greater than the length of joint pin upper end cylinder, pedestal upside is provided with the second through hole, the second through hole is threaded hole, joint pin lower end is connected by the second through hole whorl with pedestal upside, double-screw bolt lower end is provided with the first nut.Need to adjust the height of V-block time, only need be rotationally connected post, the thread end of joint pin moves up and down in the threaded hole of pedestal upside, adjusts to after the height needing, with the first nut screwing clamping joint pin, simple in structure, easy to operate.The degree of depth of the first through hole is greater than the length of joint pin upper end cylinder, can make V-block be seated on back-up block, improves the stability of V-block.
As preferably, the cylindrical outer surface of described back-up block is provided with annular knurl.In the time being rotationally connected post, annular knurl can increase friction force, handled easily.
As preferably, described connecting link is threaded rod, and pedestal is provided with third through-hole, and connecting link is through third through-hole, and connecting link two ends are provided with the second nut.Need to adjust the left and right distance of two V-blocks time, only need mobile pedestal to correct position, then tighten the second nut.
As preferably, described pedestal is made up of two rectangular parallelepipeds, and pedestal is the T font of handstand, and the bottom of pedestal is provided with groove, and described groove is the V font standing upside down, and groove extends to the edge of pedestal bottom opposite side from the edge of pedestal bottom one side.The weight that groove can alleviate support is set, and operation easily.
