Description
Technical field
The present invention relates to profile of tooth angle deviation fields of measurement, be specifically related to a kind of direct-type profile of tooth angle deviation check device.
Background technology
At present, for the detection of profile of tooth angle deviation, there are two kinds of basic skills: Photoelectric Detection and indirect detection.
Photoelectric Detection: need special photoelectric measurement equipment, has higher requirement to measurement environment, operating personnel, and measurement cost is high, measuring period is long, is not suitable for on-the-spot batch production and measures, be suitable only for sampling Detection.
Indirect detection: as shown in Figure 1, detection platform, tailstock centre, height gauge is utilized to detect two the teeth portion profile of tooth joint gardens of part in the same axis of symmetry height h1, h2 apart from detection platform basal plane, as shown in Figure 3, calculate its difference in height Δ h=h1-h2 ≈ C, two profile of tooth angle deviations are then Δ α=2arcsin Δ h/d, and wherein d is the diameter of profiled parts.
The main deficiency that indirect detection exists:
When 1, detecting, the check point in profile of tooth joint garden is difficult to accurate location, and measuring error is large;
2, measurement data will through calculating conversion, and just can obtain profile of tooth angle deviation, step is loaded down with trivial details;
3, detection platform volume is large, is not easy to in-site installation and deposits, and detects non-cutting time long.
Summary of the invention
The object of the invention is to overcome in prior art, the drawbacks such as it is loaded down with trivial details that the accuracy of detection caused by joint garden height detection is poor, angular deviation converts, solve in Photoelectric Detection and measure the problems such as cost is high, measuring period is long, the invention provides a kind of device of visual inspection part profile of tooth angle deviation.
In order to solve the problems of the technologies described above, reach technique effect, the present invention takes following technical scheme: a kind of direct-type profile of tooth angle deviation check device, it comprises pedestal, support, straight-line rolling guide set, locating centre, handwheel lift rotating equipment, locating turntable, meter, dog screw and tested part.Described support is fixedly mounted on the side of pedestal, straight-line rolling guide set is fixed on support, and being fixed on support relative on the inner side of pedestal, locating centre is arranged on straight-line rolling guide set, and the center line of described locating centre and the center line of tested part are positioned on same datum line.Described handwheel lift rotating equipment is fixed on the upper end of support, for driving locating centre to move up and down on straight-line rolling guide set, and locking tested part.Described locating turntable is arranged on the top of pedestal, and locating turntable has table bar pilot hole, and described meter is installed in table bar pilot hole.The bottom of described pedestal has dog screw mounting hole, and described dog screw is arranged in dog screw mounting hole; The center of described table bar pilot hole and dog screw mounting hole is on same datum line.Above-mentioned straight-line rolling guide set is made up of guide rail, slide block, steel ball, reverser, retainer, end cover and baffle plate etc.When guide rail and slide block do relative motion, steel ball is just along four rolling path rollings that the process on guide rail is hardened and accurate grinding processes, after slide block end steel ball enters back hole by back device (reverser) again, enter raceway again, steel ball carries out rolling movement like this again and again.Dust seal end cap is equipped with at reverser two ends, can effectively prevent dust, bits end enter slide block inside.
Further technical scheme is: the top of described pedestal has positioning spigot, and described locating turntable is arranged on the positioning spigot of pedestal.
Further technical scheme is: described meter comprises the table bar matched with it and fixes briquetting, and table bar fixes briquetting for locking meter.
Further technical scheme is: described pedestal has the stationary center matched with tested part, and the center line of described stationary center and the center line of locating centre are positioned on same datum line.
Further technical scheme is: meter is dial gauge.
The present invention compared with prior art, has following beneficial effect:
By the detected part profile of tooth center of dog screw and dial indicator head location, pedestal and locating turntable baseline circumference scale deflection determination tested part duplex spline two profile of tooth angle deviation, detection data are directly perceived, detection method is simple, measurement data is accurate, effectively avoid the drawback that measuring error is large and conversion calculating is loaded down with trivial details adopting the indirect method of measurement to produce, measure efficiency high, volume is little.
