Engine timing system assembling tool

Abstract

The invention discloses an engine timing system assembling tool, which is used for regulating the engine timing position. The engine timing system assembling tool consists of a camshaft timing chain wheel regulation device and a crankshaft timing chain wheel regulation device, wherein the camshaft timing chain wheel regulation device comprises a camshaft timing chain wheel regulation device body, a locking seat, a stop pin and a draw bar; the camshaft timing chain wheel regulation device body is in a disk-shaped structure; the excircle surface of the camshaft timing chain wheel regulation device body is provided with a stop pin avoidance slot; the stop pin is installed on the bottom of the stop pin avoidance slot; the working end surface of the camshaft timing chain wheel regulation device is provided with a ladder groove structure; the ladder groove structure is matched with a hub of a camshaft timing chain wheel; one end of the draw bar is fixedly assembled with the camshaft timing chain wheel regulation device body; and the locking seat is hinged with the camshaft timing chain wheel regulation device body. The engine timing system assembling tool disclosed by the invention has the advantages of simpleness in operation, stable performance and strong popularity and is suitable for assembling protection line bodies for engines of various machine types.

Description

technical field [0001] The invention relates to a positioning assembly tool, which is especially suitable for adjusting the rotation position of the camshaft timing sprocket (or pulley) and the crankshaft timing sprocket (or pulley) when the engine timing chain (or timing belt) is assembled. The adjustment belongs to the field of engine technology. Background technique [0002] The timing system is an important part of the engine, which mainly includes: camshaft timing sprocket (belt pulley), crankshaft timing sprocket (belt pulley) and the corresponding transmission mechanism. Its main function is to regularly control the opening and closing of the intake and exhaust valves of the engine according to the needs of the working process of each cylinder of the engine, so as to make the engine fuel mixture or air enter the cylinder in time, and the exhaust gas is discharged from the cylinder in time. Economics have a significant impact. At present, the transmission mechanism o...

Problems solved by technology

[0004] When the engine timing system is assembled by the tooling method, the tooling equipment generally consists of two parts: the camshaft timing sprocket (pulley) tooling and the crankshaft timing sprocket (pulley) tooling, but the existing tooling equipment still exists as follows Disadvantages: First, the structure of the parts on the engine needs to be changed; second, the versatility is poor, and a timing tool is only suitable for one model
