Abstract
The utility model discloses a differential carrier cross hole verticality detection tool, which comprises a standard core shaft and a measurement core shaft, wherein the middle part of the standard core shaft is provided with a through hole vertical to the axial direction of the standard core shaft, a bush is arranged in the through hole, the measurement core shaft passes through the bush, one end of the measurement core shaft is provided with a measuring rod, and the outer end of the measuring rod is provided with a dial indicator; the outer end of the measuring rod is provided with a hole, a dial indicator bush is arranged in the hole, and one end of the dial indicator passes through the dial indicator bush and is fixed through a screw arranged vertical to the dial indicator bush; and the whole measuring rod has an arc-shaped structure, and two ends of the measuring rod have linear structures. The detection tool has simple structure, and can be processed by adopting common processing equipment; and after the detection tool is put into use, the quality of the processed product can be judged on line, so the processing quality and the inspection efficiency are improved.
Description
Technical field
The utility model relates to a kind of differential carrier cross bore verticality cubing.
Background technology
Existing differential carrier cross bore verticality adopts general way to measure, specifically be to support the two bearings position with V-block, punching axle in cross bore, look for the numerical value of mandrel peak with lever indicator, then mandrel is changed in another vertical with it group hole and looked for peak, through calculating the verticality value; Another kind method is exactly that finishing is measured with three coordinates measuring equipment the back well.With general way measuring operation more complicated, and cumulative errors are also big, inconvenient and can only be after the finishing of bearing position energy measurement, can not judge in time that mismachining tolerance appears in this operation; Measure with three coordinates measuring equipment, efficient is lower and can only measure the product back of rolling off the production line, and can not judge in time whether the product space tolerance that do not roll off the production line is qualified.
The utility model content
The utility model purpose is to provide a kind of differential carrier cross bore verticality cubing, not only can guarantee the cross bore testing accuracy but also improved efficiency of measurement, and can not descend line products to carry out dimensional measurement to process, guaranteed the quality control of differential carrier cross bore manufacturing procedure.
To achieve these goals, the utility model adopts following technical scheme: differential carrier cross bore verticality cubing, comprise the benchmark mandrel and measure mandrel, benchmark mandrel middle part is provided with perpendicular to being provided with lining in the through hole of benchmark mandrel axial direction and the through hole, measure mandrel and pass the lining setting, a termination of measuring mandrel is provided with measuring staff, and the outer end of measuring staff is provided with dial gauge.
Described measuring staff outer end is provided with and is provided with the dial gauge lining in hole and the hole, and dial gauge one end passes the setting of dial gauge lining, and the screw retention by being provided with perpendicular to the dial gauge lining.
Described measuring staff integral body is arcuate structure, and the two ends of measuring staff are linear structure.
Existing measuring technique is lower to differential carrier cross bore verticality checkability, though as measuring the measuring accuracy height with three coordinates measuring equipment, must make X-ray inspection X under the product, so can not satisfy the measurement requirement of high volume production process.And the present invention not only can guarantee the cross bore testing accuracy but also has improved efficiency of measurement, and can not descend line products to carry out dimensional measurement to process, has guaranteed the quality control of differential carrier cross bore manufacturing procedure.
The present invention is the cross bore design feature according to the differential mechanism hole, be positioning reference with one group of hole earlier, measure the verticality of another group hole relative positioning benchmark, and then exchange reference position, survey the verticality in one group of remaining hole, utilize the dial bore gage reading directly to measure the relative squareness tolerance in two groups of holes.This measurement mechanism is simple in structure, adopts common process equipment just can process, and can be implemented in converted products after coming into operation and does not roll off the production line and just can judge its quality, has improved crudy and checkability.

Embodiment
Embodiment: shown in Fig. 1-2, differential carrier cross bore verticality cubing, comprise benchmark mandrel 1 and measure mandrel 3, benchmark mandrel 1 middle part is provided with perpendicular to being provided with lining 2 in the through hole of benchmark mandrel 1 axial direction and the through hole, the measurement mandrel is worn 3 and is crossed lining 2 settings, a termination of measuring mandrel 3 is provided with measuring staff 4, and the outer end of measuring staff 4 is provided with dial gauge 5.Measuring staff 4 outer ends are provided with and are provided with dial gauge lining 6 in hole and the hole, and dial gauge 5 one ends pass dial gauge lining 6 and are provided with, and fixing by the screw 7 that is provided with perpendicular to dial gauge lining 6.Measuring staff 4 integral body are arcuate structure, and the two ends of measuring staff 4 are linear structure.
Among Fig. 1, be the mandrel of two square crossings, the mandrel of level cooperates with one group of hole wherein, and vertical mandrel is put into another group hole by the hole in the middle of the horizontal mandrel.Fig. 1 right-hand member is the initial position of dial gauge measuring staff, and the dial gauge gauge head is at numerical value of this position display; When the dial gauge measuring staff rotated to left position, dial gauge showed another numerical value.The difference of two numerical value is exactly the error of perpendicularity of workpiece.
