Crankshaft test-based engine cold test sensor docking device

Abstract

The invention discloses a crankshaft test-based engine cold test sensor docking device, which comprises a connecting plate, an avoiding hole and a power connection head, two groups of fastening clamping plates for preventing a sensor plug from falling off are slidably connected in a side connecting frame, and external connecting shell sleeves are fixedly arranged at the upper end and the lower end of the side connecting frame; and a sliding type linkage pushing mechanism used for driving the fastening clamping plate to move is arranged in the external connecting shell sleeve, and an expanding type butt joint mechanism used for fixing the connecting plate and an engine is arranged on the connecting plate. According to the invention, a sleeve rod is pressed to be separated from a positioning groove in an external shell sleeve, then a button is pushed to enable a driving sliding block to move along the horizontal direction, and at the moment, two groups of fastening clamping plates move towards the inner side direction of a side connection frame to realize locking and fixing of a sensor plug; and the sensor and the connecting plate are kept in a stable power connection state when the engine is tested, so that the purpose of accurate and reliable test data is achieved.

Description

technical field [0001] The invention relates to the technical field of engine cold equipment, in particular to a sensor docking device for engine cold test based on a crankshaft test. Background technique [0002] The cold flow test is referred to as "cold test" or "cold test", and the cold flow test is a tool for detecting errors in the assembly process and defects in engine parts. Strictly speaking, cold test technology is a means of quality inspection, and it is a technology for comprehensive testing of various systems after engine assembly is completed. [0003] In the cold test of the existing engine, due to the large number of wiring harnesses and high maintenance costs, it is necessary to use the corresponding docking device to connect with the sensor wire harness first, and then connect the docking device directly to the engine to realize A quick cold test of the engine. However, when the engine is being tested, there will be a large vibration. At this time, the sen...

[0003] In the cold test of the existing engine, due to the large number of wire harnesses and high maintenance costs, it is necessary to use the corresponding docking device to connect the sensor wire harness first, and then connect the docking device directly to the engine to realize A quick cold test of the engine. However, when the engine is being tested, there will be a large vibration. At this time, the sensor harness connected to the docking device will fall off from the interface of the docking device due to the vibration of the engine. It leads to test interruption, which not only increases the difficulty of the test, but also affects the accuracy of the test data
