Engine cooler test plugging device

Abstract

The invention discloses a plugging device for test of an engine cooler, and the plugging device can be used to detect the airtightness of an internal pipeline of the engine cooler. A water pipe is fixedly connected to the engine cooler, the plugging device comprises a device support, a positioning mechanism and a plugging mechanism, the positioning mechanism is arranged on the device support and positions the water pipe in advance, the plugging mechanism is arranged on the positioning mechanism and plugs a port position of the water pipe, and the positioning mechanism cooperates with the plugging mechanism to realize plugging for test of the water pipe. The water pipe of the engine cooler is aligned and positioned rapidly effectively in a floated abutting manner, and the structure and shape of the water pipe of the engine cooler are protected. A plugging head has certain adaptive adjustment function, and can plug pipe port structures of different inclination angles, the effect of a plugging operation is improved, and the application range of the plugging device is broadened.

Description

technical field [0001] The invention relates to a test plugging tool, in particular to a test plugging device used in the process of processing and testing engine coolers, and belongs to the field of mechanical automation. Background technique [0002] In recent years, with the continuous improvement of my country's industrialization level, mechanized operations have become a major trend in industrial production. In the current industrial production, especially in the process of product processing related to the automobile industry, most operations need to be carried out in a mechanized manner. [0003] Due to the inevitable need for positioning and clamping operations in the process of product processing and testing, most of the processing enterprises are equipped with automatic positioning devices to meet the corresponding operating needs, but the existing various types of positioning and clamping There are many deficiencies in the device. [0004] Take the machining pro...

Problems solved by technology

Generally speaking, due to the relatively large manufacturing tolerance of the water pipes connected to the engine cooler, it is necessary to pre-position the pipes before the plugging operation. However, due to the special bending shape of the water pipes, when performing pre-positioning, It is difficult to achieve precise positioning of the pipeline

In this way, it will not only make the subsequent plugging test operation difficult to carry out, but also seriously affect the plugging operation effect on the water pipe port position.
