Abstract

The invention relates to a test device for testing the buffer performance of a hydraulic buffer oil cylinder and a test method thereof, the test device comprises a rack, a guide device, a counterweight vehicle and a measuring device, the guide device arranged along the vertical direction is arranged on the central axis of the rack in a penetrating manner, and the measuring device is arranged right below the guide device. A to-be-tested hydraulic buffer oil cylinder installation position is arranged in the measuring device, and the inner wall of the guiding device is in sliding fit with the side vertical face of the balance weight vehicle. The test method comprises the following steps of 1, assembling the guide device according to parameters of the hydraulic buffer oil cylinder to be tested, 2, placing the counterweight vehicle at the top end of the guide device, and measuring the stroke of the counterweight vehicle, and 3, obtaining buffer performance data through the sensor. According to the design, buffer performance data can be accurately tested through the pressure sensor and the displacement sensor, the testing range of performance testing of the testing device is effectively expanded, adjustment can be conducted according to actual testing requirements, and the application range of the testing device is effectively expanded.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for testing the buffer performance of a hydraulic buffer cylinder and a test method thereof, which is particularly suitable for testing the buffer performance of a hydraulic buffer cylinder that can fully test the buffer performance and is applicable to a wide range of buffer performance Device and its test method. Background technique [0002] With the rapid development of my country's equipment manufacturing industry, large-scale construction machinery equipment has been developed and promoted at a high speed, and these equipment often need to use the hydraulic system to provide reliable and stable power output, so the operating performance and quality of the hydraulic system are not Higher requirements are put forward. Therefore, after the processing and manufacture of the hydraulic cylinder, the relevant performance of the hydraulic cylinder needs to be inspected before leaving t...
