The U-shaped protrusion is filled up in the groove of feed screw nut's outer wall so that two components of feed screw nut and fixing pipe are fixedly connected
Together, and manufacturing process is simple, at low cost.
The utility model is achieved through the following technical solutions, a kind of connection structure of feed screw nut and fixing pipe,
Including feed screw nut and the fixing pipe for being sheathed on feed screw nut's excircle, a groove is arranged in the outer wall of the feed screw nut, described
Fixing pipe is provided with U-shaped protrusion, and the U-shaped protrusion is arranged in groove.
Preferably, one end of the feed screw nut is provided with the abutting part abutted for fixing pipe.
Preferably, the bottom of the U-shaped protrusion is abutted with the inner wall of groove.
Preferably, the inner wall of the fixing pipe and the outer wall of feed screw nut fit closely.
A kind of spinning mold, includes the die ontology above fixing pipe, and one end of the die ontology is provided with U-shaped
Pressure head, groove, fixing pipe and the U-shaped pressure head of the feed screw nut are located along the same line, and the other end of the die ontology connects
It is connected to machine tool chief axis.
The beneficial effects of the utility model：A kind of connection structure of feed screw nut and fixing pipe, including feed screw nut and set
Set on the fixing pipe of feed screw nut's excircle, a groove is arranged in the outer wall of the feed screw nut, and the fixing pipe is provided with U-shaped convex
Go out portion, the U-shaped protrusion is arranged in groove, carries out spinning to fixing pipe by spinning mold so that fixing pipe forms U-shaped
Protrusion, and the U-shaped protrusion is filled up in the groove of feed screw nut's outer wall so that feed screw nut and two components of fixing pipe
It is fixed together, and manufacturing process is simple, it is at low cost.
Description of the drawings
Fig. 1 is the attachment structure schematic diagram of the utility model feed screw nut and fixing pipe.
Fig. 2 is the structural schematic diagram of the utility model feed screw nut and another visual angle of fixing pipe.
Fig. 3 be feed screw nut, fixing pipe and spinning mold structural schematic diagram.
Specific implementation mode
1 the utility model is described further to attached drawing 3 and specific implementation mode below in conjunction with the accompanying drawings.
As shown in Figure 1, the connection structure of a kind of feed screw nut and fixing pipe, including feed screw nut 1 and it is sheathed on lead screw spiral shell
A groove 11 is arranged in the outer wall of the fixing pipe 2 of female 1 excircle, the feed screw nut 1, and the fixing pipe 2 is provided with U-shaped protrusion
21, the U-shaped protrusion 21 is arranged in groove 11.
The present embodiment carries out spinning by spinning mold to fixing pipe 2 so that fixing pipe 2 forms U-shaped protrusion 21, and will
The U-shaped protrusion 21 is pressed into the groove 11 of 1 outer wall of feed screw nut so that 2 two components of feed screw nut 1 and fixing pipe, which are fixed, to be connected
It is connected together, and manufacturing process is simple, it is at low cost.
In the present embodiment, one end of the feed screw nut 1 is provided with the abutting part 12 abutted for fixing pipe 2, further
Prevent feed screw nut 1 relatively movable with fixing pipe 2.
In the present embodiment, the bottom of the U-shaped protrusion 21 is abutted with the inner wall of groove 11, the inner wall of the fixing pipe 2
It is fitted closely with the outer wall of feed screw nut 1, further such that feed screw nut 1 is tightly fastened with fixing pipe 2.
As shown in figure 3, a kind of spinning mold, includes the die ontology 31 above fixing pipe 2, the die ontology 31
One end be provided with U-shaped pressure head 32, groove 11, fixing pipe 2 and the U-shaped pressure head 32 of the feed screw nut 1 are located along the same line,
The other end of the die ontology 31 is connected to machine tool chief axis, and machine tool chief axis is used to control the rotation and feeding of U-shaped pressure head 32, machine
Bed U-shaped 32 high-speed rotation of pressure head of main shaft drives carries out spinning to fixing pipe 2 so that fixing pipe 2 forms U-shaped protrusion 21, and will
The U-shaped protrusion 21 is filled up in the groove 11 of 1 outer wall of feed screw nut so that 2 two components of feed screw nut 1 and fixing pipe are fixed
It links together；Machine tool chief axis can ensure that the spinning size of U-shaped pressure head 32 can be accurately controlled very much, to ensure that lead screw
Nut 1 will not be spun excessively, cause malformation.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
