When the checking fixture is used for checking, firstly, the bottom surface of the air chamber support is placed on the upper surface of the base, the camshaft hole of the air chamber support faces the mandrel and is pushed in, and whether the central height of the camshaft hole of the workpiece and the parallelism of the camshaft hole and the bottom surface can meet the assembly requirement is judged by observing whether the workpiece can be smoothly pushed in and the fitting degree of the workpiece and the upper surface of the base; if the workpiece meets the requirements, the detection pins are inserted into the guide sleeves of the detection tool through the 4 support seat connecting bolt holes of the air chamber support in sequence, whether the detection pins can be inserted smoothly is judged, and whether the size and the position degree of the 4 support seat connecting bolt holes of the workpiece can meet the assembly use requirements is judged.
The utility model discloses the beneficial effect who has is:
(1) the gauge is simple in design structure and convenient to manufacture. The base and the connecting plate of the checking fixture are of L-shaped structures, and finish machining is performed after welding, so that the relative position relation among all the components is guaranteed. And the mandrel is fed into the mandrel mounting hole after finish machining according to the size of the camshaft hole of the air chamber bracket, and is tightened by using a hexagonal flange nut, so that the relative position relation is ensured. The guide sleeve is additionally arranged in the detection guide sleeve hole so as to reduce the fit clearance between the detection guide sleeve hole and the detection pin. Grinding the guide pillar part of the detection pin to ensure the requirements of excircle size and roughness; the outer surface of the upper end part of the detection pin, namely the handle part, is knurled so as to facilitate the operations of inserting and pulling during detection.
(2) The whole checking fixture is very convenient and reliable to use, detection can be completed only by simple push-pull and plug-pull operations, special requirements on a use place and an operator are not required, and whether batch air chamber supports can meet the requirements of machining or assembling use can be judged quickly and effectively. The method is very suitable for the aspects of workpiece inspection on the air chamber bracket processing site, detection and judgment of parts in an axle factory, problem analysis in the on-site assembly process of the axle assembly, defective part selection and the like.
