Embodiment Construction

[0009] Such as figure 1 , 2 As shown, the present invention includes: a base 1, a bracket 2, a vertical guide shaft 3, a clamp 4, a dial gauge 5, locking screws 6, 7, a reference shaft 8, a measured shaft sleeve 9, and a pin shaft 10. The connection method is as follows: the bracket 2 is fixed on the base 1 with two screws, the guide vertical shaft 3 is inserted into the cylindrical hole of the base 1, and then locked with screws, after the clamp 4 is set on the guide vertical shaft 3, the locking screw 6 is tightened to make It clamps the guide vertical shaft 3, the lower circular shaft of the dial gauge 5 is inserted into the cylindrical hole at the lower part of the fixture 4, the rib on the back of the dial gauge 5 is connected with the fixture 4 with a pin shaft 10, and the two ends of the pin shaft 10 are put on The retaining ring for the shaft prevents the axial movement of the pin shaft. After the locking screw 7 is tightened, the dial gauge 5 is clamped by the fixtur...

Abstract

The invention is a device to detect uniformity of the wall thickness of the sliding shaft cover. The bracket is fixed on the base by two screws, the oriented vertical shaft is inserted in columnar hole and locked by screw, the clamp is covered on the oriented vertical shaft and tightened by one knurling lock-screw to clamp the oriented vertical shaft, the circular shaft on the underside of the dial gauge is inserted in the columnar hole on that of the clamp, the rib board at the back of the dial gauge is linked with the clamp by bolt shaft, the dial gauge is clamped by the clamp by using the other knurling lock-screw, one end of the reference shaft is inserted in the circular hole of the bracket and screwed down by the screw which locked by nut, and the detected shaft cover is covered on the reference shaft. The measurement is convenient.

Description

technical field [0001] The invention relates to a fast manual shaft sleeve detection device, in particular to an oil-free lubricated sliding shaft sleeve wall thickness uniformity detection device, which belongs to the field of machinery. Background technique [0002] A kind of oil-free lubricating bushing in sliding bearings is widely used in various types of mechanical products and household appliances, and is a large-scale and wide-ranging mechanical basic part. This kind of bearing has self-lubricating properties, and generally does not need to add lubricants during the working process. Since the wall thickness and the uniformity of the wall thickness of this kind of bushing have a great influence on its performance, it is generally necessary to check whether the inner diameter and outer diameter of this kind of bushing meet the given tolerance requirements during the production process. Vernier calipers are generally used as measuring tools, but the uniformity of the wa...
