Fixtures for gasoline engines used for condition testing, on-line testing, and load durability testing

Abstract

A fixture for gasoline engines used for working condition testing, on-line testing, and load durability testing, including an adjustable bracket, a speed regulating mechanism and a connecting piece for connecting test pieces, and the speed regulating mechanism is horizontally installed on the adjustable bracket The top; the connecting piece is fixedly connected to the input drive shaft of the speed regulating mechanism; the speed regulating mechanism includes a clutch, a mounting plate, a passive disc output seat, a fixed output seat, an output drive shaft and an input drive shaft; The input shaft of the clutch is located on the side of the fixed output seat, and the output shaft of the clutch is located on the side of the output seat of the passive disc; the input shaft of the clutch is fixedly connected to the connecting piece through the transmission shaft at the input end, and the output shaft of the clutch is fixed through the transmission shaft at the output end. It is fixedly connected to the connection end of the dynamometer or load actuator. The beneficial effects of the invention are: simple structure, fast installation, uniform use of different tests; simple operation when testing different products, no need to replace tooling fixtures, and no need to readjust the center height and centering.

Description

technical field [0001] The invention relates to a fixture of a gasoline engine used for working condition testing, on-line testing and load durability testing. Background technique [0002] At present, for the small gasoline engine products produced by domestic and foreign manufacturers in the garden machinery industry, different tooling fixtures are used for different tests in gasoline engine online testing, working condition testing and load durability testing. The installation of fixtures should be complicated during online testing, resulting in low production efficiency; online testing The tooling fixture is different from the working condition test fixture, which leads to inconsistencies in the relevant test data when the product after online testing is tested in the working condition, and the load durability test (chainsaw) cannot simulate actual use. Contents of the invention [0003] The present invention aims at the problem that different tooling fixtures are used...

Problems solved by technology

[0003] The present invention aims at the problem that different tooling fixtures are used for different tests in gasoline engine on-line detection, working condition test and load durability test, and the installation of the fixtures is complicated during on-line detection, resulting in low production efficiency. A simple structure and fast installation are proposed. , Different tests can be used uniformly for gasoline engine fixtures for working condition testing, online testing, and load durability testing
