A conical tooth ring is arranged in the upper part of the tooth mould seat, and a positioning component of a circular hole is arranged at the lower part the tooth mould seat. The dial indicator frames are umbrella-shaped frame components, spherical trisection fork strips are arranged on the top, and vertical shafts are connected to the lower parts of the dial indicator frames. The bottom section of the vertical shaft is in clearance fit with the circular hole of the bottom face of the tooth mould seat and the middle section of the vertical shaft is in clearance fit with the inner hole of a planetary gear to be tested. The spherical surfaces on the top of the dial indicator frames are concentric with the spherical surface of the planetary gear to be tested which is positioned and arranged on the tooth mould seat; the three fork strips are respectively provided with one dial indicator which is installed into a through hole in a way that the dial indicator head faces downwards; through holes on the three fork strips are respectively arranged on an outer point, a middle point and an inner point of the spherical surface of the planetary gear to be tested; according to the invention, the standard planetary gear is arranged in the tooth mould seat, the three dial indicators are zeroed, then the planetary gear to be test is installed for comparative measurement, and the installation position of a cutter or a clamp is guided to be adjusted according to a real measurement result. The planetary gear spherical surface measuring device is not restricted by particular detection conditions, and is particularly applicable to the on-line detection of a production site.
Description
Technical field
The present invention relates to a kind of length measuring device, specifically, the present invention relates to a kind of device that three anchor points are measured spherical surface of planetary gear of setting.
Background technology
Planet wheel is one of strength member in the differential mechanism, and its large end face is sphere.This sphere is the benchmark mating surface of planet wheel axial limiting on the installation site, has higher shape and position of related features requirement, usually adopts the machine cut job operation to realize making, and can realize batch production after lathe, cutter and anchor clamps are adjusted to the right place.But cutter, anchor clamps must have normal wear in the machine cut process, and the alignment error self-assembling formation foozle that produces when cutter, clamp-replacing, cause product quality to descend.So, in the machine cut process, want frequent sampling Detection sphere workmanship, then adjust cutter or anchor clamps installation parameter according to measurement result, guarantee that the spherical surface of planetary gear crudy is consistent.Spherical surface of planetary gear is curved body, and its shape error can't be measured with general measurer, and prior art uses the three-dimensional detector can accurately detect planetary sphere.The three-dimensional detector is a kind of high precision detecting instrument, and testing conditions is had relatively high expectations, and is not suitable for the production scene and detects online use, so can not be as the measurement mechanism of quality control in the production run.
Summary of the invention
The present invention is not suitable for the online problem that detects mainly for prior art, propose a kind of simple in structure, easy to operate, accuracy of detection is high, the testing conditions requirement is low, is fit to the online planetary gear spherical surface measuring device that detects.
The present invention is achieved through the following technical solutions technical goal.
Planetary gear spherical surface measuring device, it comprises clock gauge, dial framework, screw and tooth die holder.Described tooth die holder is established cone gear ring align member in being, the supine planet wheel to be checked of cone gear ring location and installation ball of horizontal on the residence, and tooth die holder bottom surface is provided with the circular hole for the dial framework location and installation between two parties.Its improvements are: described dial framework is the umbrella shape frame member, the top is the third-class crouch strap of sphere, under have vertical pivot to connect, section and tooth die holder bottom surface circular hole clearance fit location at the bottom of the vertical pivot, vertical pivot stage casing and inner hole of planetary gear clearance fit to be checked, dial framework top sphere and location and installation be planetary sphere concentric to be checked on the tooth die holder, every fork bar is provided with a through hole clock gauge is installed, three through holes of pitching on the bar divide on the circumference of three different sizes, clock gauge assigns in the through hole and by screw lock down with gauge outfit, and the axis of every clock gauge all coincides with the sphere radial line.
In the said structure, be positioned at the through hole on the third-class bifurcated in dial framework top, lay respectively at midpoint between spherical surface of planetary gear outer circumferential edge to be checked, internal circle and the inside and outside circle.
The present invention compared with prior art has following good effect:
1, measure in sphere minute inside and outside, a middle three-point fix, detection architecture is simple, making is easy;
2, make spherical surface of planetary gear to be checked with three clock gauges of standard spherical surface of planetary gear zeroing and compare and measure, three clock gauge difference values show the foozle of position, and measurement result is objective, accurate;
3, plug-in mounting structure, easy for installation, it is easy, quick to detect;
4, without special testing conditions restriction, be convenient to online detection.

Fig. 1 is that structure master of the present invention looks diagrammatic cross-section.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is dial framework top structure schematic top plan view.
Fig. 4 is that dial framework vertically rotates diagrammatic cross-section.
Embodiment
The invention will be further described with reference to the accompanying drawings for the below.
Planetary gear spherical surface measuring device shown in Figure 1, it comprises clock gauge 1, dial framework 2, screw 3 and tooth mould 4.Described tooth die holder 4 is established cone gear ring align member in being, the supine planet wheel 5 to be checked of cone gear ring location and installation ball of horizontal on the residence, and tooth die holder 4 bottom surfaces are provided with the circular hole for dial framework 2 location and installation between two parties.Fig. 1, dial framework shown in Figure 32 are the umbrella shape frame member, and the top is the third-class crouch strap of sphere, and lower have vertical pivot to connect, section and circular hole clearance fit location, tooth die holder 4 bottom surface at the bottom of the vertical pivot, vertical pivot stage casing and planet wheel to be checked 5 endoporus clearance fit.The sphere concentric of Fig. 2, dial framework shown in Figure 42 top spheres and location and installation planet wheel 5 to be checked on tooth die holder 4, every fork bar is provided with a through hole clock gauge 1 is installed.Through hole on Fig. 1, the three fork bars shown in Figure 3 divides on the circumference of three different sizes, and clock gauge 1 assigns in the through hole down with gauge outfit and by screw 3 lockings, the axis of every clock gauge 1 all coincides with the sphere radial line.
During the actual use of the present invention, the standard planet wheel is placed do the engagement of tooth section on the tooth die holder 4 first, the dial framework 2 that will fill again 3 clock gauges 1 is inserted in standard inner hole of planetary gear and the tooth die holder 4 seat surface circular holes, respectively three clock gauges 1 is transferred to zero-bit.Extract dial framework 2 out, take the standard planet wheel away, planet wheel 5 to be checked changes the outfit, reinsert dial framework 2 and make manual rotation, watch the indicated value of three clock gauges 1, judge spherical surface error according to measurement result, error is judged to be certified products in tolerance band, if overproof fibrous root is made the position adjustment of cutter or anchor clamps according to situation, until sphere is up-to-standard, the present invention's repeatedly making comparisons property detection after for the first time zeroing of clock gauge 1, without the special detection condition, easy for installation, it is easy, quick to detect, and is particularly suitable for doing to detect online in the production scene.
