Abstract
The utility model disclose a locating and detecting fixture for an addendum circle of an engaging gear, which consists of a core shaft, a steel ball retaining ring, a locating ring, a left cover, a large washer, a shrink sleeve, a small washer, a cross spacer and a nut. The right end of the locating ring is of a thin-walled cylinder, the inner cavity of the opening of the cylinder is in clearance fit with the addendum circle of the engaging gear, and an open slot is arranged on the cylinder wall and is in taper fitting with the shrink sleeve. The right end of a flange arranged on the core shaft is in the shape of a circular ring, the outside diameter thereof is less than the root circle of the engaging gear. When the engaging gear is radially located by the locating ring and is axially located by the right end surface of the flange arranged on the core shaft, the located engaging gear is locked by screwing the nut, and then some components of a locating structure are removed so as to expose the detected engaging gear, and thereby, the engaging gear is conveniently detected on a gear detector. The fixture is specifically suitable for carrying out batch detection after the engaging gear is formed by finish forge.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind of mandrel class detection and localization anchor clamps.
Background technology
Engaging gear is the gear set zoarium of two kinds of different structures, and soldered tooth wherein is attached on the cylindrical gear end face.Soldered tooth is difficult to realize processing with conventional cutting working method, and precision die forging shaping at present is the optimal process method of engaging gear.Whether qualified soldered tooth tooth profile parameter that precision die forging is shaped and relevant form and position tolerance be, need under location condition, use the gear detector to detect, conventional way is to carry out endoporus finishing earlier before engaging gear detects, join tapering mandrel location with endoporus, the center pit at tapering mandrel two ends directly supports on the gear detector.This method is easy, feasible, and still, all necessary special centering datum end face of each detected member and point circle be the finishing endoporus again.Above whole operation is trouble, has the centering error, and can not in time correct the preceding working procedure problem and cause the waste of following process.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of soldered tooth point circle detection and localization anchor clamps that directly are shaped with precision forging die.The soldered tooth gear can be laid down locating device by nut lock after in a single day obtaining the location before the detection, soldered tooth tooth portion is exposed, and is convenient to do on the gear detector associated teeth parameter detecting.
The utility model adopts following technical proposals to realize technical goal.
Engaging gear point circle detection and localization anchor clamps, it is made up of mandrel, location structure and locking mechanism.Described mandrel is separated into two sections axles by flange, and right axis section is provided with external thread, and the axle two ends are respectively equipped with center pit.Described location structure is kept circle and centring ring and the left side lid, the large washer that match and is tightened up cover by the steel ball that is sleeved on the mandrel left end constituting, and the centring ring right side is the thin-walled tubular, and barrel is provided with shaft orientation opening groove, and barrel has tapering.Described locking mechanism is gone up the small washer, cross pad and the nut that are nested in proper order by the right section axle of mandrel and is constituted.Its improvements are: the flange left end on the described mandrel is the plane, and right-hand member is the annular seam.Described centring ring barrel is a taper fit with tightening up the cover endoporus, the soldered tooth point circle clearance fit of centring ring right-hand member endoporus and tested engaging gear.Described mandrel right-hand member external diameter nominal size is less than the interior hole dimension of tested engaging gear.
In the said structure, the flange right side that is located at the mandrel middle section is a kind of annular seam, and this seam external diameter is less than the root diameter of tested engaging gear.
The utility model compared with prior art has following good effect:
1, be the positioning reference of engaging gear with the cylindrical mandrel, location structure is simple, accurate positioning;
2, after the locking of tested soldered tooth gear, remove partial component the location structure, tested soldered tooth is exposed, be convenient to detect from mandrel;
3, directly cooperate and locate, before machine work, can realize the detection of soldered tooth, avoid follow-up machine work to cause waste product to waste with the soldered tooth point circle of precision forging.
Description of drawings
Fig. 1 is a structural profile synoptic diagram of the present utility model.
Fig. 2 is the stereographic map of Fig. 1.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings below.
Engaging gear point circle detection and localization anchor clamps shown in Figure 1, it is made up of location structure, mandrel and locking mechanism.Described location structure is kept circle 2 and centring ring 3 and the left side lid 4, the large washer 5 that match and tightens up cover 6 constituting by the steel ball that is sleeved on mandrel 1 left end.Described mandrel 1 is separated into two sections axles by flange, and right section axle is provided with external thread, and the axle two ends are respectively equipped with center pit.Described locking mechanism is gone up the small washer 7, cross pad 8 and the nut 9 that are nested in proper order by mandrel 1 right section axle and is constituted.In the utility model, the flange left side on mandrel 1 stage casing is the plane, and the right side is the annular seam, and this seam external diameter is less than tested soldered tooth root diameter.Described centring ring 3 barrels are taper fit with tightening up cover 6 endoporus, and centring ring 3 is towards the soldered tooth point circle clearance fit of right endoporus and tested engaging gear.Described mandrel 1 right section axle maximum gauge is less than the interior hole dimension of tested engaging gear.Said structure serves as an axle benchmark location and installation centring ring 3 with mandrel 1, left side lid 5 with tighten up cover 6 left end hole screw-internal thread fit and do moving axially with respect to centring ring 3.Since centring ring 3 with tighten up cover 6 taper fit, tighten up the cover 6 just radial compaction centring ring 3 that moves to left, centring ring 3 is towards the uniform shaft orientation opening groove of right barrel, stress deformation is directly eliminated the soldered tooth point circle tolerance clearance of centring ring 3 and engaging gear.Tightening up cover 6 moves to right and then loses compressing centring ring 3.
In the said structure, be positioned circle 3 radial locations and of engaging gear by the flange right side axial location of mandrel 1, manually screwing nut 9 locks oriented engaging gear, then from 1 left section relevant member that withdraws from the location structure of mandrel, tested soldered tooth is exposed, and is that a benchmark is installed on the gear detector at the center pit with mandrel 1 two ends under this situation.Because soldered tooth exposes, no any blocking is convenient to carry out coherent detection.The utility model structure is simple relatively, reasonable, and the location is reliable, and is easy to detect, is adapted at doing the batch detection use behind the soldered tooth precision forging.
