Title: Combination presetting and load testing machine for springs
Inventor: COLLINS HOWARD O
IPC: G01N3/00
Filed: 1968-11-26
Abstract: 1,242,606. Testing springs. NORTH AMERICAN ROCKWELL CORP. 26 Nov., 1968, No. 55963/68. Heading F2S. [Also in Division B3] A spring testing and "pre-setting" (i.e. scragging) machine has provision for presetting by reversely bending a leaf spring and for testing by bending the spring and measuring the force per unit deflection (spring rate). When the pre-setting operation is being performed, the measuring means are rendered inoperative. In use of the machine a leaf spring, e.g. a laminated vehicle suspension spring 160, is located so that its ends are attached to respective piston-cylinder actuators 132, 134 and its central region 161 is held by an assembly 44 which can be reciprocated vertically along a guideway 26 by third piston-cylinder actuator 96. To pre-set the spring, the first two cylinders are displaced in one direction (downwardly) and the third in the other (upwardly), the spring being brought from its unstressed (upwardly convex) form as shown through a substantially flat state (Fig. 5, not shown) and beyond that to a reversely curved state (Fig. 6, not shown). It may be subjected to more than one such reversal, each reversal causing a permanent set in the spring. During this process, the spring portion 161 is positively held by clamping means 56, 78. After pre-setting, the clamp is released so that the spring portion 161 merely rests on the lower element 56 of the clamp, the actuators 132 and 134 are immobilized and fluid is supplied to a fluid-pressure load cell 60, 64 the pressure in which is caused to operate an indicator 119. The actuator 96 alone is then operated to raise the spring portion 161 until the spring is substantially flat, the force necessary to do this being transmitted by way of the load cell. The spring rate is determined from the indicated magnitude of this force. After pre-setting and before testing the spring may be struck by hammers 190, 192 to relieve friction between the leaves of a laminated spring. The hammer mechanism is driven by a further piston-cylinder actuator 218 (Fig. 3, not shown). After testing, a second pre-setting operation may prove necessary, the stroke of the actuators 132 and 134 being adjustable so that the second or subsequent pre-setting can be made less severe. Fig. 9 (not shown) depicts respectively the fluid circuitry of the various actuators and the load cell and Fig. 10 depicts electric circuitry by which the fluid circuitry is controlled (by way of solenoid-operated valves). Various programs of automatic action are catered for, in particular: (a) automatically controlled presetting as described above to be followed by separately initiated and controlled testing, (b) a fully automatic cycle of preset, hammer; test. In the latter, the preset phase is made to terminate with the spring in its flat state, it is then hammered, and the load maintaining it flat is then transferred from the clamp to the load cell.
