Abstract

The invention provides a clamp improving rotary knob installation coaxiality and an assembling method using the clamp. The clamp comprises a supporting base plate, a lower plate, an upper cover plate and a movable locating mechanism, wherein the lower plate is arranged on the supporting base plate, the rear side of the upper cover plate is connected with the lower plate in a rotating mode, the front side of the upper cover plate is connected with the lower plate through clamping buckles, a height locating block is arranged on the lower plate and is arranged between the upper cover plate and the lower plate in a clamping mode, the movable locating mechanism is arranged on the lower plate, the lower plate is provided with a first installing datum plane, the movable locating mechanism comprises a locating sleeve and a movable limiting ring, the locating sleeve is arranged in the movable limiting ring in a sleeved mode, and the movable limiting ring is fixed on the lower plate. The invention further provides the assembling method using the clamp improving rotary knob installation coaxiality. The clamp improving rotary knob installation coaxiality and the assembling method using the clamp improving rotary knob installation coaxiality have the advantages of being capable of improving installation coaxiality of a rotary knob.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a tooling fixture for improving the coaxiality of knob installation and an assembly method using the tooling fixture. Background technique [0002] Combination knobs are commonly used in car audio assemblies and air-conditioning controller assemblies (generally two or more are used in one panel), which are often used for channel adjustment, volume adjustment, air speed adjustment, air volume adjustment, temperature adjustment, etc. The rotation feel of the combined knob is determined by the coaxiality between the knob cover and the mounting hole after installation and the roundness of the knob cover and the mounting hole. [0003] Since the car audio directly faces the driver and co-driver's passengers, OEMs generally require that the coaxiality between the knob cover and the mounting hole after installation and the cumulative deviation of the roundness of the knob cover and the mounting hole...
