Aspect interior hexagonal, two versions are arranged in the GB, one is GB70-76,76 years versions; One is GB70-85,85 years versions, and the said firm carries out the standard of DIN912 at present; So in the practical business operation, should note difference: wherein GB70-85 overlaps with DIN912 fully, so, do not exist difference for using new target situation; Mainly be difference to some extent between GB70-76 and the DIN912: the interior hexagonal product of M8 series, the round end of GB70-76 directly is 12.5MM, and is smaller than the 13.27MM of DIN912; The interior hexagonal product of M10 series, the round end of GB70-76 directly is 15MM, 16.27 smaller than DIN912; The interior hexagonal of M12 series, the round end of GB70-76 directly is 18MM, and is smaller than the opposite side 18.27 of DIN912; In addition, be respectively 24MM, 30MM as the round end footpath of the interior hexagonal GB70-76 of M16, M20 series little 0.33MM than DIN912.DIN912 then is respectively 24.33MM and 30.33MM.The method of making nut now mainly contains two kinds; A kind of automatic type; Another kind of type hand; For make through type hand the screw head dummy to guarantee head of screw on draw-in groove to be consistent, but type hand the inconsistent phenomenon of draw-in groove of screw head dummy can occur unlike the machinery so of automatic type.
Summary of the invention
For solving the problems of the technologies described above, hold spiral shell portion and make the consistent screw head dummy processing unit (plant) of draw-in groove cutting on the nut thereby the invention provides a kind of the location.
For realizing above-mentioned purpose; The invention provides a kind of screw head dummy processing unit (plant); It comprises body; Rotate the connecting rod be arranged on the described body, the centre position of being fixed in described connecting rod and be connected with the motor of described body interior and drive the pulley of described connecting rod rotation and the section of being fixed in described connecting rod two ends through fixed cover through conveyer belt; Be positioned at and also rotate the spiral shell portion of holding that is provided with on the described body with described section opposite position; The described spiral shell portion of holding is through the thread groove hold-down screw, and the described maximum angle of holding the rotation of spiral shell portion is to rotate to be arranged on the described body and to hold the location division that spiral shell portion and section are located along the same line with described.
Preferably, described location division comprises second fixed bar that is fixedly set in first fixed bar on the described body and is fixedly set in the end of described first fixed bar.
Preferably; One end of described second fixed bar is formed with screw thread; And an end of described first fixed bar is provided with the holddown groove that is complementary with described screw thread, and described first fixed bar is fixedly connected with described second fixed bar through the fixing of described holddown groove and screw thread.
Preferably; Described body is provided with two ends and is fixed in the rotating shaft on the described body; Described end of holding spiral shell portion is formed with the axle sleeve that is complementary with described rotating shaft, and the described spiral shell portion of holding rotates through being connected of axle sleeve and described rotating shaft and is arranged on the described body.
Preferably, described fixed cover is fixed on the described body through screw.
Preferably, be positioned at described section place and also be provided with cooling tube.
Preferably, the cooling material of described cooling tube injection is a cold oil.
The advantage of screw head dummy processing unit (plant) of the present invention is: the setting through fixed part can be so that holding the spiral shell portion anglec of rotation confirms, thereby makes the draw-in groove on the manual produced nut be consistent.
