Description

Technical Field

[0001] The utility model relates to the technical field of bearing bush production, in particular to a drilling and positioning tool for bearing bush production. Background Art

[0002] The bearing is the part where the sliding bearing and the journal contact. It is in the shape of a tile-like semi-cylindrical surface and is very smooth. It is generally made of wear-resistant materials such as bronze and anti-friction alloy. In special cases, it can be made of wood, engineering plastics or rubber. There are two types of bearings: integral and split. Integral bearings are usually called sleeves. Integral bearings are available in two types: with and without oil grooves. The bearing and the journal are fitted with a clearance fit and generally do not rotate with the shaft. In the process of producing and processing the bearing, it is usually necessary to drill holes in the bearing. During the drilling process, it is usually necessary to use positioning tooling to position and clamp the bearing.

[0003] In the process of using positioning tooling to position and clamp the bearing, two sets of clamping plates are usually used to move toward each other to position and clamp the bearing. However, the existing positioning tooling usually only has one set of clamping mechanism to clamp and position the bearing on both sides, and is unable to clamp and position the bearing on four sides. This leads to insufficient stability of the bearing, which may cause the bearing to offset during processing and affect the drilling of the bearing. At the same time, this will also lead to uneven clamping force, which may generate unnecessary stress on the bearing, which may cause deformation or damage to the bearing. Especially during the drilling process, uneven clamping force may affect the accuracy and quality of the hole. Utility Model Content
