Description

TECHNICAL FIELD

[0001] The present application relates to the field of crankshaft adjustment, in particular, to a multi-purpose turning gear tool. BACKGROUND

[0002] Turning refers to rotating a certain part of the engine to drive the piston connecting rod mechanism, valve train, gear train, etc. During the production process of the engine, turning is required to complete valve clearance adjustment, fuel supply advance angle adjustment, and compression clearance measurement, etc. Valve clearance, fuel supply advance angle, and compression clearance all have an impact on the working state of the engine. Therefore, it is necessary to turn the engine during the production process of the engine.

[0003] The invention patent with the authorization announcement number CN221169744U discloses a multi-purpose turning gear tool. The tool includes a connecting piece and a flange connected to the connecting piece. The flange includes multiple adapters, and each adapter extends in a horizontal plane away from the connecting piece. This solves the problem of poor versatility of current turning gear tools.

[0004] In the above-mentioned scheme, the flange can be adapted to multiple crankshafts by setting through holes, first and second adaptation slots on the adapters. However, the first and second adaptation slots are both open and adjacent, which affects the overall structural strength of the flange to some extent. During the adjustment of the crankshaft, the flange needs to be rotated to drive the crankshaft to rotate, so the flange will bear the reverse rotating force generated when the crankshaft rotates, thereby affecting the service life of the flange due to the overall structural strength. Therefore, we propose a multi-purpose turning gear tool. SUMMARY

[0005] To overcome the existing deficiencies, the present application provides a multi-purpose turning gear tool that can solve the problem of low overall structural strength of the flange.

[0008] In a specific embodiment, the connecting area includes a first long waist-shaped hole opened in the tool disc. The first long waist-shaped hole is provided with two first long waist-shaped holes, and the two first long waist-shaped holes are symmetrically arranged about the center of the tool disc.

[0009] In one specific embodiment, the connecting region further comprises a first fitting hole formed on the tool disc, one end of the first fitting hole is open and located on one side of the first long waist hole, the first fitting hole is provided with two, and the two first fitting holes are symmetrically arranged about the center of the tool disc.
