Technical Field
[0001] The present invention relates to the technical field of gear detection, and in particular to a universal gear detection aid and a detection method. Background Art
[0002] In gear testing technology, any gear installed with a hole is positioned by the shaft hole during testing. After hobbing, shaping or grinding, various gears positioned with internal holes need to be positioned with different diameter internal holes using testing aids. For gears with higher precision, each piece must be inspected. If the clearance between the gear reference internal hole and the testing spindle is too large, it will affect the test data.
[0003] For gears with many varieties and large differences in specifications and sizes, more testing spindles of corresponding specifications are required. The gears are installed on the testing spindles, and the accuracy is tested on the gear comprehensive tester. Too many spindle tooling will increase the production cost of the product. Summary of the invention

One end of the arm is hinged, and the other end of the inner movable arm is hinged to the external ear hole through a first rotating shaft; an annular step is convexly arranged on the outer side of the assistive device body, and the outer rotating ring is sleeved on the annular step and can rotate, and three outer pin shafts are evenly distributed on the outer end surface of the annular step, and three inner ear holes are correspondingly arranged on the inner ring of the outer rotating ring, and each outer pin shaft is connected to the corresponding inner ear hole through an outer fixed arm and an outer movable arm, wherein one end of the outer fixed arm is hinged to the outer pin shaft, and the other end of the outer fixed arm is hinged to one end of the outer movable arm, and the other end of the outer movable arm is hinged to the inner ear hole through a second rotating shaft.
[0006] The universal gear detection auxiliary tool mentioned above, wherein the auxiliary tool body is provided with a first bolt for locking the outer rotating ring and a second bolt for locking the inner rotating ring.

When the outer rotating ring is rotated clockwise, the curved arm is straightened, and the intersections of the three external fixed arms and the external movable arms simultaneously contact the outer circle of the largest single-piece detection spindle. The three-point automatic centering effect makes the axis center line of the detection auxiliary device coaxial with the axis center line of the single detection spindle. Similarly, when the outer rotating ring is rotated counterclockwise, the curved arm is bent, and the intersections of the three external fixed arms and the external movable arms simultaneously contact the outer circle of the smallest single-piece detection spindle. The three-point automatic centering effect makes the axis center line of the detection auxiliary device coaxial with the axis center line of the single detection spindle. Rotate the inner swivel ring, and when the outer swivel ring is rotated clockwise, the curved arm is tightened, and the intersections of the three inner fixed arms and the inner movable arm simultaneously contact the inner hole of the smallest single product gear. The three-point automatic centering effect makes the axis line of the detection auxiliary tool coaxial with the axis line of the inner circle of the product gear. Similarly, when the inner swivel ring is rotated counterclockwise, the curved arm is bent, and the intersections of the three inner fixed arms and the inner movable arm simultaneously contact the inner hole of the largest single product gear. The three-point automatic centering effect makes the axis line of the detection auxiliary tool coaxial with the axis line of the single detection spindle.
[0008] The beneficial effects of the present invention are as follows: the present invention realizes the variable diameter of the inner hole and outer circle three-point positioning diameter of the testing aid through the structural design of the testing aid, with a crank arm structure evenly distributed at three points, and the three-point positioning diameter is changed by rotating the outer rotating ring or the inner rotating ring to change the extension and contraction of the crank arm, and then the diameter of the three-point positioning diameter is changed, and then it is fixed by bolts after the change. The diameter of the inner hole three-point positioning diameter of the testing aid changes to adapt to the inspection spindle with different positioning shaft diameters, and the diameter of the outer circle three-point positioning diameter of the testing aid changes to adapt to the inspected gear with different positioning aperture diameters. When the testing aid uses three-point positioning, the radial change flexibility is large and the adaptability is wide. BRIEF DESCRIPTION OF THE DRAWINGS
