BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an assembling apparatus for a camshaft and an integral housing,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an assembly device for a camshaft and an integral housing, and a method of assembling the housing and a method for assembly using the same. .

Generally, the camshaft is installed on the upper portion of the engine so as to open and close the valve interlocked with the rotation of the crankshaft.

Therefore, the camshaft is provided with a cam sprocket connected to the crankshaft and the timing belt at one end, and the shaft is formed with cams having different phases and spaced apart from each other at predetermined intervals so as to be able to open the valve by rotation.

An example of a camshaft support structure for fixing such a camshaft is disclosed in Japanese Patent Laid-Open Publication No. Hei 01-249904.

The camshaft support structure disclosed in the prior art document 1 includes a downwardly convex semi-circular groove formed on the upper portion of the cylinder head and an upwardly convex cap coupled with the groove to form a circular journal bearing, The camshaft is rotatably supported by the shaft.

However, when assembling the cap in a state in which the camshaft is seated in the groove of the semicircular shape, the camshaft can not be seated in the correct position, so that an error occurs and it is difficult to precisely align the camshaft.

Therefore, in order to solve such a problem, an integral housing in which a journal bearing for supporting the camshaft is formed integrally with the housing has been developed.

One example of the integral housing for supporting such a camshaft is disclosed in Japanese Patent Application Laid-Open No. 2008-157062 (hereinafter referred to as "Prior Art Document 2").

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing an integral housing according to a prior art document 2. FIG.

As shown in FIG. 1, the integral housing structure for supporting the camshaft disclosed in the prior art document 2 includes a longitudinal member 11S formed in parallel and a front lateral member 11F formed across both ends of the longitudinal member 11S. A rear transverse member 11R and a transverse transverse member 11M and a journal bearing 13M for inserting a shaft is formed in the transverse transverse member 11M.

However, since the inner diameter of the journal bearing 13M is larger than the base circle of the cam but smaller than the diameter of the cam lobe, there is a problem that it is impossible to insert the cam shaft in a state in which the cam is formed.

Therefore, in order to assemble the camshaft into the integral housing, the cam and shaft must be separated from each other and assembled into the integral housing.

[

Although the heat insulating material 46 is provided in the heating rod 42 in this embodiment, it is needless to say that a heat insulating material can be provided on the cooling rod 62 as required. It is preferable that the heat insulating material 46 is made of a ceramic material which is excellent in heat resistance and can not be easily deformed. In order to compensate the brittleness of the ceramic material, it is preferable to provide a buffer member 48 at the tip of the heat insulating material 46. The buffer member 48 provided here is preferably made of a heat resistant material such as silicon which is superior in heat resistance to organic rubber.

Hereinafter, a method for assembling a camshaft and an integral housing according to an embodiment of the present invention will be described with reference to the accompanying drawings.

7 is a flow chart showing a method of assembling a camshaft and an integral housing according to an embodiment of the present invention.

According to an embodiment of the present invention, there is provided a method of assembling a camshaft and an integral housing, the method comprising: a housing preparation step (S10) of moving the housing to an assembling position; a jig moving step (S20) of moving the jig to the assembling position; An alignment step (S30) of elevating a jig moved to an assembling position to align the center of the insertion hole of the cam seated on the jig with the center of the housing journal bearing, and inserting a heating rod into the insertion hole of the cam to expand the cam (S50) of inserting a shaft into the insertion hole of the cam through a through-hole of the housing, and a step of inserting the cooling rod into the insertion hole of the cam together with the shaft, (S60).

The housing preparing step S10 is a step of moving the housing H to the assembling position as shown in FIG. 4, in which the housing H is mounted on one side of the housing moving means 10 and the roller 12 is rotated Moves the housing (H) to an assembling position where the guide (24) intersects.

The jig moving step S20 is a step of moving the jig 22 to the assembling position and moving the carriage 26 on which the jig 22 is installed to move the jig 22 to the housing H).

The aligning step S30 is a step of raising the jig 22 moved to the assembling position so that the center of the insertion hole 72 of the cam C seated on the jig 22 and the center The jig 22 simultaneously ascends and the centers of the insertion holes 72 of the cam C and the journal bearings of the housing H are aligned with each other.

The cam extension step S40 is a step of extending the cam C by inserting the heating rod 42 into the insertion hole 72 of the cam C so that the heating rod 42 of the high- H through the through hole 82 of the housing H and the heating rod 42 that has entered the housing H passes through the insertion hole 72 of the journal bearing and cam C . The cam C is heated by the heating rod 42 input into the insertion hole 72 of the cam C and the insertion hole 72 of the cam C is expanded.

The shaft inserting step S40 is a step of inserting the shaft S into the insertion hole 72 of the cam C through the through hole 82 of the housing H. [ At this time, the cooling rod 62 is inserted into the housing H together with the shaft S in a state where the cooling rod 62 is inserted into the shaft S. The shaft (S) advances forward until the front end of the shaft (S) is exposed out of the housing (H). At this time, the tip of the cooling rod (62) comes into contact with the tip of the heating rod (42). Since the heat insulating member 46 is provided at the tip of the heating rod 42 at this time, heat loss can be prevented and the heating rod 42 and the cooling rod 62 It is possible to prevent damage beforehand. Since the heating rod 42 is in contact with the tip of the shaft S, the shaft S is prevented from sagging so that the shaft S can be inserted into the correct position of the cam insertion hole 72.

Next, in the cooling rod taking-out step S60, the cooling rod 62 is inserted into the insertion hole 72 of the cam C together with the shaft S, and then the cooling rod 62 is moved in the advancing direction of the shaft S In the opposite direction. When the cooling rod 62 is carried to the outside of the housing H, the cooling rod 62 moves to the rear of the guide 24.
