Embodiment Construction

[0022] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0023] A kind of equipment used in the online automatic testing method of semi-finished engine, such as figure 1 As shown, it includes a platform body 4, a dynamometer 7 fixed on the platform body, an exhaust docking device 8, and a feeding line 6 passing through the platform body. A plurality of clamps 5 are arranged on the feeding line. A semi-finished engine 1 is fastened on the fixture, and a process flywheel 2 is pre-fixed on the output shaft of the semi-finished engine. Under the simultaneous action of fixing, it can be fixed temporarily and quickly for testing operations. The positioning box in this embodiment is a welded box structure, and a clamp limit surfac...

Abstract

The invention discloses an online automatic testing method for a semi-finished engine, and belongs to the technical field of manufacturing of engines. The online automatic testing method for the semi-finished engine comprises the following steps: (1) fixing a process flywheel on an output shaft of a semi-finished engine, then fixing the semi-finished engine on a clamp to form testing combined bodies, and placing the testing combined bodies on fixed positions of a feeding line one by one to circulate; (2) fixing and connecting the testing combined bodies; (3) starting a start device so that theengine starts successfully; (4) starting a forced cooling device, and carrying out loading test of a dynamometer and data acquiring recording under the control of a control device; and (5) after loading test is finished, returning various testing assemblies to finish testing. Testing on the dynamic performance of the semi-finished engine can be realized, full-automatic mechanical operation is carried out in the process, and replaces troublesome manual operation, the operation efficiency is improved, and the labor intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of engine manufacturing, and in particular relates to an on-line automatic testing method of a semi-finished engine. Background technique [0002] Small thermal power machines (engines) are generally self-contained and can operate autonomously without additional accessories. A semi-finished engine is a product that lacks an inertia flywheel, a starting mechanism, and a cooling fan compared to a finished engine, and cannot operate autonomously in the factory state. However, for the purpose of quality control, it is necessary to test the power performance of the product in a hot running state. For the hot test of the product, at present, the method of assembling the process accessories to form a simulated process machine and then testing, and then dismantling the process accessories after the test is completed. Although this method can complete the test, it has the problems of complicated operation, high labo...
