Problems solved by technology
[0003] When using the existing drilling device to drill the metal bobbin, it is necessary to manually place a single bobbin on the cylinder to limit the bobbin, then use a drill to drill the bobbin, and finally manually insert the bobbin into the bobbin. The bobbin is removed from the cylinder, and the processing speed is seriously reduced by manual loading and unloading, and the hand is easily scratched by the drill bit during the loading and unloading process; the bobbin will vibrate during the drilling process, and the bobbin in the vibrating state It is prone to deflection, causing the drilling holes on the metal disc to be not a regular circle, which affects the drilling accuracy

Embodiment Construction
[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.
[0025] like figure 1 and image 3 As shown, this embodiment provides a sewing machine metal bobbin positioning and rotating automatic drilling machine, including a horizontal base plate 1, and a plurality of vertical support rods 2 are fixedly installed on the upper surface of the base plate 1, and the support rods 2 are elastic telescopic rods , the top of several support rods 2 is fixedly installed with a screening mechanism 3; the screening mechanism 3 includes a cylindrical screening barrel 301, the inner bottom surface of the screening barrel 301 is a conical surface, the axis of the screening barrel 301 is vertical and the screen is in a vertical state. The bottom of the material cylinder 301 is fixedly installed with a discharge pipe 302 that...

The invention belongs to the technical field of sewing machine accessories, and in particular relates to an automatic drilling machine for positioning and rotating a metal bobbin of a sewing machine. There is a screening mechanism; a drilling mechanism is installed on the upper surface of the bottom plate under the discharge pipe; before the metal bobbin is drilled by the present invention, a plurality of bobbins can be manually poured into the screening cylinder at one time; In the process, it is not necessary to manually load and unload each bobbin, which speeds up the processing speed and avoids the damage to the human hand caused by the drill bit; the present invention locates the bobbin through the attractive force of the magnet block to the bobbin, and simultaneously clamps the bobbin by clamping The plate clamps the edge of the bobbin, which avoids the situation that the hole on the metal disc is not a regular circle due to the deflection of the bobbin due to vibration, thereby ensuring the precision of the hole.
Description
technical field [0001] The invention belongs to the technical field of sewing machine accessories, in particular to an automatic drilling machine for positioning and rotating a metal bobbin of a sewing machine. Background technique [0002] The bobbin is an important part of the sewing machine and is generally made of plastic or metal materials; the metal bobbin consists of two metal discs and a cylinder connecting the two metal discs. Drill evenly spaced round holes. [0003] When using the existing drilling device to drill the metal bobbin, it is necessary to manually set a single bobbin on the cylinder to limit the position of the bobbin, then use a drill to drill the bobbin, and finally manually drill the bobbin. The bobbin is removed from the cylinder, and the processing speed is seriously reduced by manual loading and unloading, and the hands are easily scratched by the drill bit during the loading and unloading process; the bobbin will vibrate during the drilling pro...
