Shock absorber clamping automatic centering device and shock absorber testing machine using the device

Abstract

The invention discloses an automatic centering device for shock absorber clamping, which comprises a screw rod controlled by a steering hand plate on the base, a universal self-aligning bearing arranged on the top of the screw rod, a universal shock absorber support seat, and The upper pressing plate arranged on the base column, the upper pressing plate is provided with a connecting rod clamping groove, and the connecting rod clamping groove and the shock absorber support seat are on a vertical line; use the shock absorber testing machine of the device to clamp the above shock absorber Tighten the automatic centering device on the generator. In the process of adjusting the hand plate to clamp the shock absorber, the shock absorber support seat can realize the automatic centering of the shock absorber under the action of the universal self-aligning bearing, and realize the automatic vertical of the shock absorber, thus effectively Avoid the generation of lateral additional force, effectively reduce the measurement error and improve the accuracy of the test. The invention has the advantages of simple, reasonable and compact structure, convenient operation, time-saving and labor-saving, high efficiency, safety, stability, good passability, effective reduction of production cost, automatic centering and high accuracy of dynamometer test.

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...

Problems solved by technology

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
