Abstract
The utility model discloses an integrated measuring head for measuring the span of a measuring ball of an external gear, which comprises ball head inserting parts and an annular clamp spring ring. The clamp spring ring is an axial steel wire check ring, and the clamp spring ring is sleeved in an annular groove on a cylinder axis section of each ball head inserting part to form an external tension structure. Each ball head inserting part is a heteromorphic integrated structure, the ball head of a measuring end of each ball head inserting part is coaxially connected with a cylinder axis through a cone axis. The ball head inserting parts are used in pair, the diameter D1 and the tolerance range of the paired ball heads are equal, and the distance L from the center of each ball head to the large end face of the cone axis is equal. The two ball head inserting parts are respectively inserted in the axial holes of the end face of a gauge button matched with a caliper, and the two ball head inserting parts are in clearance fit with each other and are connected by the clamp spring ring in a tensing and floating way. When in measuring, under the push of the axial force of the gauge button of the caliper, the large end face of the cone axis of each ball head inserting part is firmly propped against the end face of the arranged gauge button so as to realize high-precision detection along with the caliper. The integrated measuring head disclosed by the utility model adopts the integrated structure, thereby can realize precise detection at a time, is convenient to operate, and is high in measuring efficiency.
Description
Technical field
The utility model relates to a kind of annex of length measuring device, and specifically, the utility model relates to a kind of conjuncted measuring head that is used to measure the outer rotor sphere distance.
Background technology
Involute urve outer rotor, involute outer spline and triangle male splines all belong to a class outer rotor part, and such part has the parameter of a sphere distance by name to need to detect.Existing general measurer can not be directly used in measurement, must do to measure indirectly by related accessories.The concrete measurement is steel ball or the pole of putting same diameter in the outside of two teeth, uses the spacing of two steel balls of miking or pole then, and this spacing is sphere distance.Although prior art can accurately be measured, the measurer that is used to detect and the steel ball that matches or pole be for dividing a body structure, and annex is installed difficultly during detection, and it is more difficult that measurer and annex accurate cooperates, and its testing result and operators'skills have quite big relation.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of conjuncted measuring head that is used to measure the outer rotor sphere distance, and this measuring head is simple in structure, easily is connected with measurer, and measuring operation is convenient, the measuring accuracy height.
The utility model is achieved through the following technical solutions technical goal.
Be used to measure the conjuncted measuring head of outer rotor sphere distance, it is made up of the jump ring circle of bulb plug-in unit and annular.Described jump ring circle is an axle-steel silk back-up ring, and the jump ring snare is contained in and constitutes outer Tensioning structure in the annular groove on the bulb plug-in unit cylinder shaft part.Its improvements are: described bulb plug-in unit is special-shaped conjuncted structure, and the bulb of its measuring junction is connected with cylinder axis is coaxial by the short axis of cone, and two bulb diameter D of pairing are used in the pairing of bulb plug-in unit
1And tolerance range equates that bulb center to the distance L of short axis of cone large end face equates.
In the said structure, axial hole clearance fit on the cylinder shaft part of bulb plug-in unit and the gage button end face of supporting milscale, short axis of cone large end face diameter D
2Equal the gage button diameter of supporting milscale.
The utility model compared with prior art has following good effect:
1, conjuncted simple in structure, make easily;
2, easy to connect with the gage button of supporting milscale, be directly used in sphere distance and detect, be convenient to operation, measurement result is accurate;
3, one-time-reach-place detects the detection efficiency height.
Description of drawings
Fig. 1 is that the utility model structure master looks synoptic diagram.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
The conjuncted measuring head that is used to measure the outer rotor sphere distance shown in Figure 1, it is made up of the jump ring circle 2 of bulb plug-in unit 1 and annular.Described jump ring circle 2 is an axle-steel silk back-up ring, is a kind of standard component.Jump ring circle 2 is sleeved on and constitutes outer Tensioning structure in the annular groove on the bulb plug-in unit 1 cylinder shaft part.Described bulb plug-in unit 1 is special-shaped conjuncted structure, and the bulb of its measuring junction is connected with cylinder axis is coaxial by the short axis of cone.Two bulb diameter D of pairing are used in 1 pairing of bulb plug-in unit in the utility model
1And tolerance range equates that bulb center to the distance L of short axis of cone large end face equates.Present embodiment is used to detect the conjuncted measuring head of the sphere distance of driving shaft involute outer spline, and because of male splines tooth depth 4mm, so the bulb diameter of selecting is Φ 2mm, the ball of this diameter belongs to standard ball series.For the ease of the metering of school zero-sum, bulb center to the distance L of short axis of cone large end face is the bulb diameter value in the present embodiment.
Two of counterpart application bulb plug-in units 1 are inserted into respectively on the gage button end face of supporting milscale in the axial hole in the utility model, and both are that clearance fit and floated by jump ring circle 2 tensioners connects.Down moving to trying hard to recommend during measurement at microspindle, make the short axis of cone large end face of bulb plug-in unit 1 and institute join the gage button end face, to realize making high Precision Detection with milscale by real.In order not hinder detection, the short axis of cone large end face diameter D of bulb plug-in unit 1
2Equal the gage button diameter of supporting milscale.
The utility model adopt conjuncted measuring head with supporting milscale float and be connected, this structure accomplishes that one-time-reach-place detects, detecting operation makes things convenient for, the efficiency of measurement height.
