Description

Technical Field

[0001] The invention relates to the field of spline detection, and in particular to a multifunctional external spline comprehensive inspection tool. Background Art

[0002] The existing external spline inspection fixtures only consider the most basic inspection requirements of the spline in their design. They can only control the size of the spline tooth side and the spline diameter (minor diameter, major diameter or forming circle diameter), and cannot meet the actual production inspection requirements such as spline tooth direction, concentricity of the spline tooth side and the spline outer circle. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a multifunctional external spline comprehensive inspection tool to solve the problem of non-concentricity between the spline tooth side and the spline major diameter and the detection problem of the spline tooth direction.

[0004] The objective of the present invention is achieved through the following technical scheme: the multifunctional external spline comprehensive inspection tool comprises a smooth ring gauge and a spline ring gauge, a smooth ring gauge is arranged on each side of the spline ring gauge, a large diameter detection hole for detecting the large diameter of the spline is opened in the center of the smooth ring gauge, a tooth measurement detection hole for detecting the spline tooth side is opened in the center of the spline ring gauge, the spline ring gauge and the two smooth ring gauges are coaxially arranged so that the large diameter detection hole and the tooth measurement detection hole are concentric; a plurality of waist-shaped locking holes are evenly distributed along the surface circumference of each smooth ring gauge away from the spline ring gauge, the same number of threaded holes are opened at positions corresponding to the waist-shaped locking holes on the spline ring gauge, the locking bolts pass through the waist-shaped locking holes and the threaded holes in turn, and the smooth ring gauge and the spline ring gauge are locked and fixed.

[0005] As a further technical solution, there are three waist-shaped locking holes.

[0006] As a further technical solution, the fixing position of the locking bolt on the waist-shaped locking hole is adjusted as the smooth ring gauge rotates, thereby changing the contact position between the large-diameter detection hole and the spline to be measured.

[0007] The beneficial effects of the present invention are as follows: by using this multifunctional external spline comprehensive inspection fixture, the problem of non-concentricity between the spline teeth and the spline outer diameter caused by inconsistent center holes or other reasons of the workpiece can be effectively identified; the lengthened design of the spline part of the inspection fixture can effectively control the spline tooth direction, and at the same time has the detection function that a traditional spline ring gauge should have.

[0011] The present invention will be described in detail below with reference to the accompanying drawings:

[0012] Example: As attached Figure 1 , 2 As shown, this multifunctional external spline comprehensive inspection fixture comprises a smooth ring gauge 1 and a spline ring gauge 2, wherein a smooth ring gauge 1 is arranged on each side of the spline ring gauge 2, a large diameter detection hole 6 for detecting the large diameter of the spline is opened in the center of the smooth ring gauge 1, a tooth measurement detection hole 7 for detecting the spline tooth side is opened in the center of the spline ring gauge 2, the spline ring gauge 2 and the two smooth ring gauges 1 are coaxially arranged so that the large diameter detection hole 6 and the tooth measurement detection hole 7 are concentric; three waist-shaped locking holes 3 are evenly distributed along the surface circumference of each smooth ring gauge 1 away from the spline ring gauge 2, and the same number of threaded holes 4 are opened at positions corresponding to the waist-shaped locking holes 3 on the spline ring gauge 2, and the locking bolts 5 pass through the waist-shaped locking holes 3 and the threaded holes 4 in turn, and lock and fix the smooth ring gauge 1 and the spline ring gauge 2.

[0013] The fixing position of the locking bolt 5 on the waist-shaped locking hole 3 is adjusted as the smooth ring gauge 1 rotates, thereby changing the contact position between the large-diameter detection hole 6 and the spline to be measured.

[0014] The working process of the present invention is as follows: during the inspection, the spline to be tested is passed through the major diameter inspection hole 6 and the tooth measurement inspection hole 7 in turn, and the tooth shape, tooth direction, spline cumulative error and spline major diameter of the spline to be tested are detected at the same time, and the problem of the spline teeth and the spline outer diameter not being concentric due to the inconsistency of the center hole of the workpiece or other reasons is effectively prevented from error identification. When the smooth ring gauge 1 is worn after a certain period of use of the inspection fixture, the locking bolt 5 can be loosened to rotate the smooth ring gauge 1 by one pitch for adjustment to avoid the worn area (this adjustment needs to be completed with the help of the spline calibration plug gauge), and then the smooth ring gauge 1 and the spline ring gauge 2 are locked again, and they can be used again, extending the service life of the inspection fixture.

[0015] By using this multifunctional external spline comprehensive inspection fixture, it can effectively prevent errors in the identification of the non-concentricity between the spline teeth and the spline outer diameter caused by inconsistent center holes or other reasons. The extended spline part of the inspection fixture can effectively control the spline tooth direction, and at the same time has the detection functions that traditional spline ring gauges should have.

[0016] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and inventive concept of the present invention should fall within the protection scope of the claims attached to the present invention.
