Flexible quick-changing locating device

Abstract

The invention discloses a flexible quick-changing locating device. The flexible quick-changing locating device is suitable for flexibly producing different kinds of steering knuckles. A fixture body is fixed with a machine tool workbench through keys and bolts, the fixture body is provided with lateral and front locating plates, the lateral and front locating plates are respectively connected with the fixture body and an angle plate through bolts, the angle plate is connected with the fixture body through bolts, a locating plate is located through locating pins and angle plate bayonets and fixed on the angle plate through bolts, a workpiece is located on the locating plate through the locating pins and bayonets of the locating plate and compressed through a press block, the press block is fixed on a connecting bar through bolts, the connecting bar is connected with an oil cylinder push rod through bolts, and the oil cylinder push rod controls the compressing and loosening of the press block through the hydraulic system under program control. According to the flexible quick-changing locating device, the user only needs to change the locating element when changing varieties, the tool storage space can be reduced, the tool management is facilitated, the locating mode is practical, the locating precision is high, the labor intensity of the operator for changing the fixture is greatly alleviated, the operation is facilitated, the change time is short, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing equipment, in particular to a device for precise positioning and rapid replacement of fixtures when realizing multi-variety flexible production of steering knuckles. Background technique [0002] At present, the processing of the steering knuckle king pin hole of the automobile front axle is generally guaranteed by a fixture with the same steering inclination angle as the king pin hole. However, if the production line produces multiple types, because the kingpin holes of the steering knuckles of each type have different steering inclination angles, when the line type is switched, the corresponding fixtures need to be replaced to ensure the positioning and machining accuracy of the workpiece. Due to the heavy weight of the fixtures used, the replacement is complicated, and the time for line change and adjustment is long, which affects the production capacity of the production line ...
