Abstract
The utility model relates to a friction welding and broaching tooth hollow shaft with an internal spline for a vehicle motor, one end of which is an internal spline, and the other end is a hollow shaft with a blind hole, and the friction welding is completed by a left part and a right part; the process mainly comprises two steps, wherein one step is that the spline end of the shaft is processed into an internal spline in a tooth pulling mode; and secondly, all parts of the product are connected together in a friction welding mode. The friction welding is not only suitable for butt welding of the same material, but also suitable for butt welding of different materials, so that two sections or three sections of the product can be made of different materials on the premise that the welding strength can be guaranteed. The manner of friction welding includes, but is not limited to, continuous drive friction welding and inertia friction welding. The utility model discloses a mode shaping of broach is used to the spline end, and more traditional gear shaping process cost is lower, and the beat is faster, can process the minor-bore internal spline that the gear hobbing is difficult to process again.
Description
Technical Field
The utility model belongs to the technical field of axle spare part technique and specifically relates to a friction welding adds automobile-used motor internal spline hollow shaft of broach.
Background
Most of the existing shaft parts for automobiles are solid parts, and in order to meet the development trend of light weight of automobiles, the manufacture of hollow shaft parts becomes the focus of technical improvement. Compared with other gear forming modes, the tooth pulling process has the advantages of faster beat and lower cost, but is only suitable for through hole shaft parts. The friction welding mode is suitable for a revolving body, can enable the welding strength to reach the same level as that of a base metal, and is a production and manufacturing mode which is very suitable for hollowing an automobile shaft. The technology of combining the broaching teeth with the friction welding is a novel processing mode of the internal spline shaft of the vehicle motor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a friction welding adds automobile-used motor internal spline hollow shaft of broach
The purpose of the utility model is realized through the following technical scheme:
a friction welding and broaching tooth hollow shaft with internal splines of a vehicle motor is characterized in that one end of the hollow shaft is provided with the internal splines, the other end of the hollow shaft is provided with a blind hole, and the hollow shaft is formed by a left part and a right part through friction welding.
A friction welding and broaching tooth hollow shaft with internal splines of a vehicle motor is characterized in that one end of the hollow shaft is provided with the internal splines, the diameter change of the two ends of the hollow shaft is large, the other end of the hollow shaft is provided with a through hole, and the hollow shaft is formed by a left part and a right part through friction welding.
A hollow shaft with internal splines and large diameter-changing ends is a hollow shaft with through holes at the other end, and is formed by a left part, a middle part and a right part through friction welding.
A hollow shaft with internal splines at one end and blind holes at the other end is made up of left part, middle part and right part through friction welding.
The process mainly comprises two steps, wherein the first step is that the spline end of the shaft is machined into the internal spline in a tooth pulling mode.
And secondly, all parts of the product are connected together in a friction welding mode. The friction welding is not only suitable for butt welding of the same material, but also suitable for butt welding of different materials, so that two sections or three sections of the product can be made of different materials on the premise that the welding strength can be guaranteed. The manner of friction welding includes, but is not limited to, continuous drive friction welding and inertia friction welding.
Compared with the prior art, the utility model has the positive effects that:
the spline end is formed in a tooth pulling mode, the cost is lower than that of a traditional gear shaping process, the beat is faster, and a small-caliber internal spline which is difficult to machine due to gear hobbing can be machined.
The machined internal spline is connected with other parts in a friction welding mode, so that the manufacturing of the hollow blind hole and hollow through hole reducing shaft which saves more materials is realized, and the lightweight manufacturing trend of automobile parts is met.
