Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and
It is not used in the restriction present invention.
As in Figure 2-4, a kind of positioner for CNC tube bending machine, described CNC tube bending machine includes lathe mandrel 9,
Described positioner includes left flange plate 1, right ring flange 2 and the spring 3 being arranged between left and right flanges dish, in institute
The inner side end stating left and right flanges dish is respectively arranged with annular groove 5, and the both ends of described spring 3 are separately positioned on correspondent method
In the annular groove 5 of blue dish, described left flange plate 1 or right ring flange 2 are provided with mandrel 4, described core along its axial centre
Spacing between the ring flange end face that the axial end of axle 4 is corresponding is 3mm～5mm, in described left and right flanges dish any one
Ring flange can overcome the elastic force of spring 3 to be axially moveable relative to another ring flange, and another ring flange described is curved with numerical control
Lathe mandrel 9 end face of pipe machine is fixing to be connected, and the spacing that described left and right flanges dish moves axially relatively controls at 3mm～5mm
Within, the overall axial length of described positioner is consistent with lathe mandrel 9 length taking down part on CNC tube bending machine, to protect
