The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide the engine camshaft and exempt from to tear open positioning tool.
In order to solve the technical problem, the utility model provides a technical scheme exempts from to tear open positioning tool for engine camshaft: comprises a positioning block; positioning teeth matched with the teeth of the engine cam gear are symmetrically arranged at two ends of the positioning block, a plurality of positioning teeth are arranged, and a connecting hole is formed in the center of the positioning block; the shapes and the sizes of the positioning teeth are designed according to the positions matched with the engine cam gear teeth when in use, so that the tooth surfaces of the adjacent 2 positioning teeth are attached to the tooth surfaces of the engine cam gear teeth inserted into the positioning teeth, and the engine cam gear teeth cannot rotate; the disassembly-free positioning tool for the engine camshaft further comprises a handle.
As an improvement, the thickness of the positioning block is smaller than or equal to the thickness of an engine cam.
As an improvement, the number of the unilateral positioning teeth of the positioning block is more than or equal to 3.
As an improvement, one end of the handle is bent into an L shape, and the bent end of the handle is inserted into the connecting hole and fixed through welding.
As a modification, the outer contour of the handle inserted into the connecting hole portion is matched with the contour of the connecting hole, and the connecting hole is in a prism shape.
As an improvement, the positioning block is made of a metal material with high hardness.
Compared with the prior art, the utility model the advantage lie in: the utility model discloses can realize the exempting from of engine camshaft and tear open the location, the location is accurate reliable, simple structure, and convenient operation has fine practicality.
