CN201519934U - Timing assembly tool for wedge type camshaft - Google Patents

Abstract

A timing assembly tool for a wedge type camshaft is characterized in that the assembly tool is rectangular, the front ends of the long edges of the rectangle are wedge-shaped, concave notches are formed in the middle at the front ends of the long edges of the rectangle, and long bolt holes are formed below the concave notches. The utility model has the advantages of simple structure, accurate timing, etc.

Description

Wedge type camshaft timing assembly tool

Technical field

The utility model belongs to the technical field of camshaft timing assembly tool, particularly wedge type camshaft timing assembly tool.

Background technology

At present, increasing engine works all are the timing assembling methods that adopts the fixed crankshaft camshaft.The timing assembling of fixed crankshaft camshaft needs to adopt special-purpose bent axle and camshaft timing assembly tool.The timing assembly tool of camshaft is difference along with the difference of camshaft timing design.Camshaft timing assembly tool of the present utility model is the engine that adopts rear end keyway timing at camshaft.Traditional camshaft timing assembly tool is the design of one flat plate type, utilizes the gap flat board to be inserted in the keyway of camshaft rear end to realize camshaft timing to fix.Consider machining deviation, because the width of each camshaft rear end keyway is all inequality, the gap of camshaft timing assembly tool and camshaft keyway is also different, simultaneously because the existence in gap, actual engine timing and theoretical some deviation of meeting bring certain influence can for like this performance of engine.

Summary of the invention

The utility model purpose provides a kind of wedge type camshaft timing assembly tool.

The technical solution of the utility model is achieved in that

Wedge type camshaft timing assembly tool is characterized by: it is a rectangle, has concave indentation in front end middle part, the long limit of rectangle, and the concave indentation below has the stay bolt hole, and the front end on the long limit of rectangle is a wedge type.

The utlity model has characteristics such as simple in structure, accurate timing.

Specific embodiments

Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.

Wedge type camshaft timing assembly tool is characterized by: it is a rectangle 1, and the front end on rectangle 1 long limit is a wedge type 4, has concave indentation 2 in front end middle part, the long limit of rectangle, and concave indentation 2 belows have stay bolt hole 3.

Embodiment:

As Fig. 1, Fig. 2 and shown in Figure 3, front end of the present utility model is a wedge type, and it can fill up the gap of timing assembly tool and camshaft rear end keyway; Adjusting camshaft 5 during assembling earlier makes camshaft rear end keyway parallel with top surface of cylinder cover 7, insert wedge type camshaft timing assembly tool then, beat wedge type camshaft timing assembly tool gently, guarantee that wedge type camshaft timing assembly tool and camshaft rear end keyway are very close to each other, utilize the screwed hole of giving valve chamber cover on the cylinder cap again, by bolt 6 wedge type camshaft timing assembly tool is fixed on this position, realizes the accurate timing of camshaft.

Claims (1)

1. wedge type camshaft timing assembly tool, it is characterized by: it is rectangle (1), the front end on the long limit of rectangle (1) is wedge type (4), has concave indentation (2) in front end middle part, the long limit of rectangle (1), and concave indentation (2) below has stay bolt hole (3).
