Abstract

The invention discloses a universal fixture for processing a plate spring inclined hole of a heavy-duty automobile front axle. The universal fixture comprises a substrate, a left graduated disk assembly and a right graduated disk assembly respectively arranged on the left end and the right end of the substrate, and a cross beam surface plate with two ends being respectively connected with a left graduated disk and a right graduated disk. The universal fixture is characterized in that a left positioning seat assembly is matched and connected onto the left end part of the cross beam surface plate; and a right positioning seat assembly is matched and connected onto the right end part of the cross beam surface plate. The universal fixture can ensure each part to be standard and universal, and not only can meet the requirement of processing of workpieces with different heights and different lengths, but also can meet the requirement of processing of plate spring holes of workpieces with different included angles.

Description

technical field [0001] The invention relates to a machining fixture, in particular to a universal fixture for machining oblique holes of front axle leaf springs of heavy vehicles. Background technique [0002] With the development of the market economy, the needs of users are constantly changing, the speed of replacement of the front axle of heavy-duty vehicles is accelerating, and the variety is also increasing. Therefore, the order is small and the diversification of products is more and more obvious, resulting in Multi-variety, small and medium-sized batch production mode is becoming more and more prominent. In order to meet the multi-variety and small-batch production mode, a variety of tooling and fixtures are required conventionally, which reduces production efficiency and increases production costs. However, it is not difficult to find out through careful observation and summary that the structure of the front axles produced by small batches and multi-variety special...
