Description

Technical Field

[0001] The utility model belongs to the technical field of standard wheel clamping devices, and in particular relates to a double-meshing standard wheel clamping and adjusting device. Background Art

[0002] The double-meshing gear tester can be used to measure the radial comprehensive deviation of cylindrical gears and the radial comprehensive deviation of one tooth. It is widely used in the machinery manufacturing industries such as automobiles and agricultural machinery. The gear to be measured is positioned by the upper and lower centers. When measuring, the standard wheel is first meshed with the workpiece, and the motor shaft under the standard wheel drives the standard wheel to rotate, and the workpiece stops after rotating one circle.

[0003] Currently standard wheel clamping devices such as Figure 1 As shown, it consists of a motor spindle, a bead sleeve, a series of gaskets, and locking bolts. The standard wheel needs to be adjusted in height by selecting appropriate gaskets to be stacked so that the tooth width of the gear being measured is completely wrapped by the standard wheel tooth width to meet the measurement standard. Since the height adjustment using gaskets is discontinuous, this solution has a certain degree of flexibility, but it is not universal and cannot meet the needs of all parts. In addition, the process of selecting gaskets is cumbersome. It seriously affects the debugging time of part replacement. How to conveniently adjust the height of the standard wheel and improve the efficiency of part replacement is particularly important. Utility Model Content

When the standard wheel is in a suitable position, a locking member is installed on the upper end of the standard wheel, and the axial position of the standard wheel is limited by the limiter and the locking member. The filling member in the gap between the standard wheel and the screw is used to isolate the standard wheel from the screw, and at the same time ensure that the standard wheel does not deflect when rotating.
