Abstract
The core roller and the core roller sleeve of the existing bearing ring cold rolling machine are connected by drilling holes at one end of a core roller shaft to tap inner threads and then locking the inner threads and the core roller sleeve by screws. In order to solve the problems, the invention aims to provide a core roller of a bearing ring cold rolling machine. The invention has simple structure, obviously improves the mechanical strength of the core roller shaft, and greatly reduces the processing difficulty of the core roller due to the adoption of the external thread design.
Description
Technical Field
The invention relates to the field of bearing processing, in particular to a core rod of a bearing ring cold rolling machine.
Background
As shown in attached figures 1 and 2, the connection between the core roller and the core roller sleeve of the existing bearing ring cold rolling machine is that an inner thread is drilled and tapped at one end of the core roller shaft and then is locked with the core roller sleeve by a screw, and the structure has the defects of greatly reducing the mechanical strength of the core roller shaft, being difficult to process, being difficult to break due to the too thin strength of the core roller locking screw, and seriously influencing the normal production due to the scrapping of the core roller and the rolling wheel caused by the breakage of the locking screw.
Disclosure of Invention
In order to solve the problems, the invention aims to provide a core roller of a bearing ring cold rolling machine.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows: a screw is arranged outside one end of the core roll shaft.
Drawings
FIG. 1 is a schematic view of a prior art core roll;
FIG. 2 is a cross-sectional view of FIG. 1;
FIG. 3 is a schematic diagram of the structure of the present invention.
In the figure, 1 is a core roll body; 2 is a core roll shaft; 3 is the core roller shaft external thread; 4 is the traditional core roller internal thread.
Detailed Description
The invention will now be further elucidated with reference to the drawing.
As shown in the attached figure 3, the core roller shaft 2 is provided with an external thread 3 near the tail end, and the core roller shaft is matched with a proper nut to realize the tight connection with the core roller sleeve.
The invention has simple structure, improves the mechanical strength of the core roller shaft, and greatly reduces the processing difficulty of the core roller due to the adoption of the external thread design.
Claims (1)
1. A core roller of a bearing ring cold rolling machine is characterized in that an external thread (3) is designed at the position, close to the tail end, of a core roller shaft (2).
