Embodiment Construction

[0020] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0021] Unless otherwise expressly stated otherwise, throughout the specification and claims, the term "comprising" or its transformations such as "including" or "including" will be understood to include the stated elements or components, and not Other elements or other components are not excluded.

[0022] Such as Figure 1 to Figure 4 As shown, according to a specific embodiment of the present invention, a pulley assembly phase inspection device is composed of a pulley disk and a central sleeve. The central shaft sleeve is provided with a key groove and a zero mark is provided on the pulley. The phase check The device is used to detect whether the keyway is aligned with the zero score line. The phase check device includes a...

Abstract

The invention discloses a belt pulley assembly phase detection device, which comprises a cylindrical sleeve and an alignment screw, wherein the cylindrical sleeve is provided with a cylindrical hole, the cylindrical hole is in sliding match with an outer circumference of a central axle sleeve, one side of the end part of the cylindrical sleeve extends to form a convex arc edge, the radius of the convex arc edge is consistent with that of a disc, the radial direction of the convex arc edge is provided with a line seam notch, the side wall of the cylindrical sleeve is provided with a screw hole, the central line of the screw hole, the central line of the line seam notch and the central line of the cylindrical hole are in the same plane, and when the cylindrical sleeve sleeves the outer circumference of the central axle sleeve, the screw hole and a key groove have the consistent height; and the alignment screw is provided with a conical tail part, and the alignment screw is in threaded match with the screw hole. In the case of phase detection, the cylindrical sleeve sleeves the outer circumference of the central axle sleeve, the alignment screw is screwed to enable the conical tail part to be embedded in the key groove, and whether the line seam notch and a zero scribed line are aligned is detected visually. The phase detection device has a simple and reasonable structure, and the use is convenient.

Description

Technical field [0001] The invention relates to the field of mechanical tools, and in particular to a phase checking device for belt pulley assembly. Background technique [0002] The pulley assembly phase checking device is a common device for engine assembly. Generally, the pulley is composed of a central shaft sleeve, an intermediate rubber body, and a wheel disc. The central sleeve has a keyway and the wheel disc has a "0" mark. When the engine is assembled and debugged, the fuel injection advance angle is usually adjusted according to the "0" scale of the pulley. The alignment between the center of the keyway and the "0" engraved line on the wheel is related to the accuracy of adjusting and recording the fuel injection advance angle, and ultimately to the engine's factory performance and emission indicators. Currently, expensive electrical measuring devices are generally used to accurately observe the alignment between the center of the keyway and the "0" engraved line of ...
