The measuring device provided by the utility model is not limited by particular detection conditions and is especially applicable to online detection of a production field.
Description
Technical field
The utility model relates to a kind of length measuring device, and specifically, the utility model relates to a kind of device that three anchor points are measured the planet wheel sphere of setting.
Background technology
Planet wheel is one of strength member in the differential mechanism, and its large end face is a 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, adopts the machine cut job operation to realize making usually, after lathe, cutter and anchor clamps are adjusted to the right place, can realize producing in batches.But cutter, anchor clamps must have normal wear in the machine cut process, and the alignment error that produces when cutter, clamp-replacing forms foozle naturally, cause product quality to descend.So, in the machine cut process, want frequent sampling Detection sphere workmanship, adjust cutter or anchor clamps installation parameter according to measurement result then, guarantee that planet wheel sphere crudy is consistent.The planet wheel sphere is a 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 Detection instrument, and testing conditions is had relatively high expectations, and is not suitable for the online detection in production scene and uses, so can not be as the measurement mechanism of quality control in the production run.
The utility model content
The utility model is primarily aimed at the problem that prior art is not suitable for online detection, 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 planet wheel sphere measurement mechanism of online detection.
The utility model is realized technical goal through following technical proposals.
Planet wheel sphere measurement mechanism, it comprises clock gauge, dial framework, screw and tooth die holder.Said tooth die holder is established awl gear ring align member in being, the awl gear ring location and installation sphere planet wheel to be checked up of horizontal on the residence, and tooth die holder bottom surface is provided with the circular hole that supplies the dial framework location and installation between two parties.Its improvements are: said dial framework is the umbrella shape frame member; The top is the third-class crouch strap of sphere, has vertical pivot to connect down, section and tooth die holder bottom surface circular hole clearance fit location at the bottom of the vertical pivot; Vertical pivot stage casing and planet wheel endoporus 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, and every fork bar is provided with a through hole clock gauge is installed, and 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 with gauge outfit down, and the axis of every clock gauge all coincides with the sphere RADIAL.
In the said structure, be positioned at the through hole that dial framework top trisection is stuck, lay respectively at midpoint between planet wheel sphere outer circumferential edge to be checked, internal circle and the inside and outside circle.
The utility model compared with prior art has following good effect:
1, on sphere, divide inside and outside, middle three-point fix to measure, detection architecture is simple, making is easy;
2, make planet wheel sphere to be checked with three clock gauges of standard planet wheel sphere 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, online detection is convenient in no special testing conditions restriction.
Description of drawings
Fig. 1 is that the utility model structure master looks diagrammatic cross-section.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is a dial framework top structure schematic top plan view.
Fig. 4 is that dial framework vertically rotates diagrammatic cross-section.
Embodiment
According to accompanying drawing the utility model is described further below.
Planet wheel sphere measurement mechanism shown in Figure 1, it comprises clock gauge 1, dial framework 2, screw 3 and tooth mould 4.Said tooth die holder 4 is established awl gear ring align member in being, the awl gear ring location and installation sphere planet wheel to be checked 5 up of horizontal on the residence, and tooth die holder 4 bottom surfaces are provided with the circular hole that supplies 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, have vertical pivot to connect down, 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.
During the actual use of the utility model, the standard planet wheel is placed do the engagement of tooth portion on the tooth die holder 4 earlier, the dial framework 2 that will adorn 3 clock gauges 1 more is inserted in standard planet wheel endoporus and the tooth die holder 4 seat surface circular holes, transfers to zero-bit to three clock gauges 1 respectively.Extract dial framework 2 out, take the standard planet wheel away, planet wheel 5 to be checked changes the outfit; Again insert dial framework 2 and do manually rotation, the indicated value of watching three clock gauges 1 is judged 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, up-to-standard until sphere; The utility model making comparisons property detection repeatedly after clock gauge 1 zeroing for the first time, no special detection condition, easy for installation; Detect easily, quick, be particularly suitable for doing online detection in the production scene.
