Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an engine set device used for exhaust gas testing of an assembled engine, which is a war mount that allows the engine to be mounted and carried in and out at a position different from the test position. This invention relates to an engine set device equipped with a vehicle, and in particular, the platform vehicle is equipped with a front and rear mounting mechanism that can be adjusted according to the type of engine, and is equipped with an actuator necessary for operating the engine. This invention relates to an engine set device that is provided with a surface plate having a positioning guide and a clamping mechanism after the loading platform vehicle is carried in.

BACKGROUND ART Conventionally, engines that have been assembled and maintained during the manufacturing process are subjected to rotational tests, and the final process includes testing their exhaust gas characteristics.

So far, when testing the rotation of this type of engine,
Front and rear mounting brackets are installed on a surface plate around which various test instrumentation layers are set, and the front and rear mounting brackets are slid, extended and retracted depending on the type of engine, and a hoist is used. The engine was to be attached by hanging it up.

<Problems to be Solved by the Invention> Therefore, there is a drawback that setting and offsetting the engine with respect to the surface plate is extremely time-consuming, and therefore, a lot of time is required for the back and forth work, and the testing efficiency is significantly reduced. As a result, there was a disadvantage of increased costs in the testing process.

Also, for example, there is an engine set device shown in Japanese Utility Model Application Publication No. 51-63005, but it has the drawback that the clamp position can only be adjusted in the vertical direction relative to the truck, and the horizontal position relative to the test device cannot be accurately determined. There was also the problem that tests for each mode could not be conducted in the same way as an actual vehicle because the mission could not be mounted on a rack.

The object of the present invention is to solve the problems of the engine setting device based on the above-mentioned prior art, and to quickly set and offset the engine with respect to the surface plate.
It is an object of the present invention to provide an excellent engine set device that allows tests to be performed with the transmission attached and is useful for the field of test technology application in the automobile industry.

<Means and operations for solving the problem> In order to solve the above-mentioned problem, the structure of the present invention, which is based on the above-mentioned claims, is based on the type of engine in which the transmission is installed. Correspondingly, after adjusting the posture of the front mounting mechanism and rear mounting mechanism on the upper part of the chassis of the chassis, the engine was hung and properly mounted on the chassis. When the mount vehicle is brought into the test position through the machine, even if the horizontal mount vehicle is tilted when the aircraft is moved in and out, the positioning guide of the guide holder provided on the surface plate allows the mount to be moved to the test position. The flange of the car was guided and positioned, and then the clamp mechanism of the surface plate was iron-fitted to the tapered hole of the receiving bush attached to the bottom of the war platform car to fix the platform car, and various tests were conducted. Technical measures have been taken to ensure that
