Abstract
The utility model discloses an assembled camshaft. The assembled camshaft consists of a front section shaft (1), a rear section shaft (2) and a positioning pin (3), wherein the front end of the rear section shaft (2) is processed with a central blind hole; the tail end of the front section shaft (1) is processed with a shaft head forming interference fit with the central blind hole; the joint between the shaft head and the central blind hole is on the shaft neck between certain two adjacent cams on the camshaft; and the positioning pin (3) is installed in the pin hole of the rear section shaft (2) and used for positioning in connection of the front section shaft (1) and the rear section shaft (2). The assembled camshaft can be produced with the existing camshaft production equipment, and has the advantages of accurate positioning, firm connection, reliable strength and the like.
Description
Technical field
The utility model relates to a kind of camshaft, particularly a kind of assembled camshaft.
Background technique
Present domestic Camshaft Production equipment can only process single-piece length 1.5 meters with interior camshaft, the camshaft that surpasses 1.5 meters generally all adopts Bolt Connection, this assembled camshaft has all been considered assembly space when design.For the overlength part that does not design assembly space, if according to conventional method production, only purchase main equipment and just can process, but therefore present domestic this kind equipment that still do not have also can't process this class overlength camshaft.
Summary of the invention
The purpose of this utility model is to provide a kind of assembled camshaft, and this structure camshaft makes length surpass 1.5 meters and the camshaft that do not design assembly space and is processed into possibility.
For achieving the above object, the solution that the utility model adopts is: this assembled camshaft comprises leading portion axle and back segment axle, wherein the front end at the back segment axle is processed with central blind hole, be processed with the spindle nose that forms interference fit with central blind hole at the leading portion the tip of the axis, the joint of spindle nose and central blind hole is on the axle journal between certain adjacent two cam on the camshaft.
The front end of above-mentioned back segment axle also is equipped with the locating stud of locating usefulness when the front and rear sections axle connects.
Camshaft described in the utility model can be connected and composed by a plurality of leading portion axles and back segment axle.
Course of working of the present utility model is: earlier the overlength camshaft is divided into two or three at suitable position, each section processed alone, center nose end with the back segment axle heats then, be pressed in the center hole of back segment axle with the spindle nose of locating stud location again the leading portion axle, after the cooling of back segment axle, spindle nose just forms interference fit and the leading portion axle firmly is connected with the back segment axle with center hole.
The utility model is owing to adopt segmentation processing, therefore can utilize existing Camshaft Production equipment to produce, simultaneously owing to utilized the cold contraction principle of metallic material, and when connecting, adopted the locating stud location, therefore advantages such as the utlity model has accurate positioning, be connected firmly, intensity is reliable does not need to reserve assembly space yet.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is described in further detail below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in drawings, the utility model is made up of leading portion axle 1, back segment axle 2 and locating stud 3, and wherein the end at leading portion axle 1 is processed with spindle nose, is processed with central blind hole at the front end of back segment axle 2, and spindle nose is fitted in the central blind hole, forms interference fit with central blind hole.Simultaneously the front end at back segment axle 2 also is processed with pin-and-hole, and locating stud 3 is installed in the pin-and-hole, locatees when being used for leading portion axle 1 and being connected with back segment axle 2.Because the size of axle journal is relatively large on the camshaft, so the joint of spindle nose and central blind hole is located on the axle journal, to guarantee camshaft enough intensity arranged.
The utility model camshaft can be combined by the multistage axle.
Claims (3)
1. assembled camshaft, comprise leading portion axle (1) and back segment axle (2), it is characterized in that: the front end at back segment axle (2) is processed with central blind hole, end at leading portion axle (1) is processed with the spindle nose that forms interference fit with central blind hole, and the joint of spindle nose and central blind hole is on the axle journal between certain adjacent two cam on the camshaft.
2. assembled camshaft according to claim 1 is characterized in that: the front end at back segment axle (2) also is equipped with the locating stud (3) of locating usefulness when front and rear sections axle (1,2) connects.
3. assembled camshaft according to claim 1 and 2 is characterized in that: described camshaft is connected and composed by a plurality of leading portion axles (1) and back segment axle (2).
