Problems solved by technology

However, during the filling process, the actual filling volume may be more than the designed filling volume, which affects the expected performance of the hydraulic mount.
[0005] The cup of the hydraulic mount is made of rubber. During the filling process of the hydraulic mount, the cup may bulge and deform, which will increase the volume of the liquid chamber under the hydraulic mount and cause the actual amount of liquid to be filled. , so it is very necessary to design a tooling that controls the filling volume of the hydraulic mount by preloading

Embodiment Construction

[0048] The invention will be further described below through specific examples and in conjunction with the accompanying drawings.

[0049] The embodiment of the present invention is a certain type of hydraulic mount 4, which is clamped and pre-pressurized. The X, Y, and Z directions in the following description coincide with the coordinate axis directions defined in the drawings.

[0050] Such as Figures 1 to 3 As shown, a hydraulic mount pre-pressurization filling tool includes a slide 1, two hydraulic mount clamping mechanisms 2, a pre-load positioning assembly 3 and a hydraulic mount support mechanism 5, the slide 1 can be used for filling liquid The position is adjusted on the machine platform 7, and after the position is adjusted, it is fixed on the liquid filling machine platform 7 by bolts, and the two hydraulic suspension clamping mechanisms 2 are symmetrically fixed on the slide seat 1 with bolts, which are used for hydraulic suspension. Apply a compressive force; ...

Abstract

The invention discloses a hydraulic suspension pre-pressing liquid filling tool which comprises a sliding seat which is connected to a liquid filling platform in a position adjustable manner; two hydraulic suspension clamping mechanisms which are symmetrically fixed on the sliding seat and are used for applying pressing force to the hydraulic suspension; a hydraulic suspension supporting mechanismwhich is fixedly arranged on the sliding seat, is positioned between the two hydraulic suspension clamping mechanisms and is used for supporting the hydraulic suspension; and a pre-pressing fixing assembly which is fixedly installed on the hydraulic suspension supporting mechanism, is provided with a shaping protruding part which is matched with a leather cup of the hydraulic suspension in shapeand prevents the leather cup of the hydraulic suspension from deforming in the liquid filling process, and is matched with the two hydraulic suspension clamping mechanisms to clamp and fix the hydraulic suspension. The hydraulic suspension pre-pressing liquid filling tool has the advantages of being simple in structure, reliable in work, high in universality, easy to operate, low in manufacturingcost and the like, and the consistency of the liquid filling amount can be effectively guaranteed.

Description

technical field [0001] The invention relates to a liquid filling tool, in particular to a hydraulic mount pre-press liquid filling tool, which is suitable for pre-press liquid filling of different types of hydraulic mounts. Background technique [0002] Hydraulic mounts are vibration damping components used in automotive powertrains and are widely used in the automotive industry. [0003] The hydraulic mount is a complex part composed of many parts. In addition to the main spring, flow channel plate, decoupling membrane and cup, a special liquid (usually ethylene glycol) is also filled inside it. [0004] In order to fill the interior of the hydraulic mount with ethylene glycol, it is necessary to fill the hydraulic mount with a filling machine. However, during the filling process, the actual filling volume may be more than the designed filling volume, which affects the expected performance of the hydraulic mount. [0005] The cup of the hydraulic mount is made of rubber. ...
