Vibration damper clamping automatic centering device and vibration damper testing machine using device

Abstract

The invention discloses a vibration damper clamping automatic centering device. The vibration damper clamping automatic centering device comprises a lead screw arranged on a base and controlled by a hand disk, a universal automatic aligning bearing and a universal vibration damper supporting seat which are arranged on the top end of the lead screw, and an upper pressing plate arranged on a base column. The upper pressing plate is provided with a connecting rod clamping groove. The connecting rod clamping groove and the vibration damper supporting seat are arranged on one vertical line. A vibration damper testing machine using the device is characterized in that the vibration damper clamping automatic centering device is installed on a working device. When the hand disk is adjusted to clamp a vibration damper, aligning and automatic centering of the vibration damper supporting seat can be realized under the effect of the universal automatic aligning bearing, and the vibration damper can be vertical automatically, so that the generation of a lateral additional force is prevented, the measuring error is effectively reduced, and the accuracy of the test is improved. According to the invention, the structure is simple, reasonable and compact; the operation is simple, time saving, labor saving and high in efficiency; the safety and stability are realized; the universality is good; the production cost is effectively reduced; automatic centering is realized; and the accuracy of an indicator test is high.

Description

technical field [0001] The invention relates to the technical field of shock absorber performance testing equipment, in particular to a shock absorber clamping automatic centering device and a shock absorber testing machine using the device. Background technique [0002] In the manufacturing process of the shock absorber, the performance detection of the shock absorber is a crucial work. However, the traditional testing equipment - Schenck table, when performing the performance test of the shock absorber, it is necessary to use a fixed fixture to fix the shock absorber on the testing equipment, because different types of shock absorbers have different external dimensions and models. They are not the same, often causing each size and model of shock absorber to correspond to a kind of fixture. There are many types of test fixtures. Every time a new product is released, corresponding test fixtures need to be prepared, which increases the cost of the enterprise. There are hundr...

However, the traditional testing equipment - Schenck table, when performing the performance test of the shock absorber, it is necessary to use a fixed fixture to fix the shock absorber on the testing equipment, because different types of shock absorbers have different external dimensions and models. They are not the same, often causing each size and type of shock absorber to correspond to a kind of fixture. There are many kinds of test fixtures. Every time a new product is released, it is necessary to prepare corresponding test fixtures, which increases the cost of the enterprise.

There are hundreds of types of shock absorber products in our factory, and there are nearly a hundred types of testing fixtures. On the one hand, there are problems such as various types, inconvenient management, and poor working conditions. , the operation is inconvenient, the installation and disassembly are very troublesome, and it needs to be clamped and fastened, and auxiliary tools such as wrenches are needed, so the work efficiency is very low; The additional force directly affects the performance of the dynamometer test, and it is difficult to guarantee the accuracy of the test data
