Abstract
Disclosed is a bevel gear bore arc chamfering depth measuring tool, comprising a gauge stand, a scale, a steel ball, and a flat, wherein the scale is disposed upon the flat via the clamping of the gauge stand; the rod end of the scale is vertically downward facing one surface of the arc chamfering of the to-be-measured workpiece bore; the steel ball is placed at the workpiece bore arc chamfering for automatic positioning; and the to-be-measured workpiece is moved upon the flat to make the top of the steel ball placed below the rod end of the scale, thus to form the contact measuring structure. Before the measurement, a standard workpiece and the steel ball are employed for the zero setting of the scale, and then the zero position can be used for determining whether the arc chamfering depth dimension of the to be measured workpiece bore is qualified or not. The bevel gear bore arc chamfering depth measuring tool directly displays the measuring result in a quantized manner with high measuring precision, and facilitates the subsequent and quantitative adjustment of the processing amount.
Description
Technical field
The utility model relates to a kind of measurer of measuring length dimension, and specifically, the utility model relates to a kind of bevel gear bore circular arc depth of chamfering measurer.
Background technology
Bevel gear endoporus in the automobile gearbox is provided with circular arc chamfering, and this circular arc chamfering degree of depth determines the installation site precision.The industry usually adopts in process of production feeler gauge to make the bore circular arc chamfering and measures, and this kind observational measurement technology is easy, quick, can accomplish effective measurement.But the prior art measuring accuracy is very low, can not quantize deviate, is unfavorable for instructing the timely reconditioner processing capacity of operative employee.
The utility model content
The utility model is mainly for the deficiencies in the prior art, proposes that a kind of syndeton is simple, processing ease, and measuring accuracy is high, and can directly quantize to indicate the bevel gear bore circular arc depth of chamfering measurer of testing result.
The utility model is achieved through the following technical solutions technical goal.
Bevel gear bore circular arc depth of chamfering measurer, it comprises dial framework, scale, steel ball and flat board; Described scale is seated on the flat board by the dial framework clamping.Improvements are: directly to inner hole of workpiece circular arc chamfering to be measured one side, steel ball is placed to inner hole of workpiece circular arc chamfering place and automatically locates the table rod end of described scale vertically downward, and the steel ball top places under the table rod end of scale and consists of the contact measurement structure.
In the said structure, the adapted scale is dial gauge, if measuring accuracy requires then adapted clock gauge of height.
The utility model compared with prior art has following good effect:
1, contact location structure simple for dull and stereotyped and workpiece end face, locates reliably;
2, the height dimension vertical survey is easy, and detection efficiency is high;
3, value display measurement result, measuring accuracy is high, is convenient to subsequent quantizatiion and adjusts cutting output.
Description of drawings
Fig. 1 is the utility model structural upright synoptic diagram.
Embodiment
The below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Shown in Figure 1 is the embodiment of bevel gear bore circular arc depth of chamfering measurer, it comprise dial framework 1,
Scale 2, steel ball 3 and dull and stereotyped 4.Described scale 2 is seated on dull and stereotyped 4 by dial framework 1 clamping, and scale 2 is dial gauge in the present embodiment.Scale 2 is installed by the table rod end vertically downward, directly to inner hole of workpiece circular arc chamfering one side to be measured, is pressed workpiece for measurement bore circular arc size Selection steel ball 3, workpiece for measurement bore circular arc radius is SR19.05mm in the present embodiment, so the steel ball 3 diameter S φ 38.1 that select.Selected steel ball 3 put wait surveys inner hole of workpiece circular arc chamfering place automatically to locate, make steel ball 3 tops place formation contact measurement structure under the table rod end of scale 2 at mobile workpiece for measurement on the flat board 4.Cooperate with steel ball 3 with standard workpiece first before the measurement and do scale 2 zeroing processing, then remove standard workpiece, use workpiece for measurement instead and measure, scale 2 offset from zero place values are the actual error value, and error amount is judged to certified products in tolerance band, otherwise is unacceptable product.The utility model directly quantizes the display measurement result, and measuring accuracy is high, is convenient to follow-up value and adjusts cutting output.But most important is the utility model dispense operations worker on-the-spot use on station, satisfies real-time testing requirement, can avoid in batches overproof accident to occur.
