Embodiment approach

[0038] According to a preferred embodiment, the pressing mechanism 14 includes: a base part 141, the base part 141 is vertically movable mounted on the fixed bracket 13; and a pressing part 142, the pressing part 142 is mounted on the At the bottom of the base part 141, the cavity S1 of the press-down part 142 has a first port 143 open downward and the vacuum is carried out through the second port 144 arranged on the side wall, and the inside of the press-down part 142 It also includes a mandrel 145 , which is installed in the cavity S1 of the pressing part 142 in an elastically movable manner. The leak detection method further includes that after the vacuum degree in the enclosed space reaches a predetermined value, the press-down mechanism 14 no longer applies pressure to the hydraulic torque converter to be tested and / or no longer applies pressure to the hydraulic torque converter to be tested. Instead of evacuating the closed space, the closed space is completely closed. ...

Abstract

This application relates to the field of leak detection, and discloses a leak detection device and detection method for a hydraulic torque converter, including: a translation support, which is horizontally movable on the frame, and The bracket is provided with a support seat for supporting the hydraulic torque converter to be tested; the fixed bracket is fixed on the frame and is located above the frame, and the fixed bracket is vertically movable There is a press-down mechanism, which is connected with a vacuum device; in the state where the hydraulic torque converter to be tested supported by the support base is pressed downward by the press-down mechanism, the press-down mechanism A closed space is formed between the hydraulic torque converter to be tested, and the closed space communicates with the vacuum pumping device, and also includes a vacuum degree sensor for real-time detection of the vacuum degree in the closed space. According to the technical solution of the present application, non-destructive detection of the sealing performance of the hydraulic torque converter can be realized.

Description

technical field [0001] The present application relates to the field of leak detection, and more specifically, to a detection device and detection method for the seal of a hydraulic torque converter. Background technique [0002] Torque converter is an important device in mechanical transmission. Generally speaking, a hydraulic torque converter includes a pump wheel, a turbine wheel and a guide wheel. The pump wheel is connected with the drive shaft, and is used to convert the mechanical energy input by the drive shaft into the kinetic energy and pressure of the liquid by virtue of the centrifugal force, and then transmit it to the The turbine connected with the driven shaft realizes the output of power. In a torque converter, the turbine and the impeller are the main rotating elements, and the flow of fluid in the torque converter needs to ensure adequate sealing. Therefore, during the assembly process of the hydraulic torque converter, there is a very high requirement on ...
