U-bolt testing apparatus

摘要

A U-bolt testing apparatus includes a pair of motors coupled to and selectively driving a pair of spindles. The spindles include sockets which are selectively movable vertically and horizontally as may be desired and which are placed over the U-bolt nuts. A U-bolt to be tested is placed on the chassis table with the component parts that are to be retained or clamped within the U-bolt and the U-bolt characteristics are tested by advancing the nuts onto the U-bolt threaded ends. In the alternative, a holding fixture is provided for securely retaining the U-bolt during testing. U-bolts having various different shapes and length of legs can be accommodated and tested by the apparatus. A computer controls the torque of the motors and nuts being advanced on the U-bolt threaded ends and monitors strain gauges which are attached to the U-bolt legs. The test data and characteristics of the tested U-bolts are viewable on an output module connected to the computer.
