Description

Technical Field

[0002] The application (patent) number is: CN202011479444.X. A turning machine for engine maintenance, comprising a base, a rotating platform, a main support and a secondary support; the rotating platform is horizontally and rotatably installed on the top of the base, and a power device connected to and driving the rotating platform to rotate is provided in the base; the main support and the secondary support are respectively fixed on both sides above the rotating platform, and an engine to be repaired is installed between them; a driving device for driving the engine to rotate is provided in the main support. When the turning machine is working, the engine to be repaired is installed and fixed between a first turning tray and a second turning tray, and the worm in the main support is driven to rotate by manually shaking the rocker, and the worm drives the worm wheel to rotate. In actual application, when the engine is installed on the main support and the secondary support, when the rotating engine is in a horizontal state or an inclined state, with the axis of the main support as the center line, there is a large difference in the weight of the engine parts on both sides, resulting in asymmetric weight on both sides of the base, and poor stability. In particular, when the engine is in a horizontal state and the screws are manually tightened, the weight is biased and the manual tightening of the screws is applied, which is easy to cause rollover and safety hazards.

[0003] The adjustable support device for engine maintenance, with application (patent) number: CN202110682576.0, includes a bottom movable support mechanism, an engine debugging and fixing mechanism, and an auxiliary support mechanism.

The support plate is pushed to rotate at the top of the support rod by adjusting the telescopic support member. The support angle of the support plate can be adjusted so that the engine is stably supported. Since manual adjustment is required, the operation is inconvenient and affects the engine rotation operation. Summary of the invention
