The magnetic suction type screwdriver head device used in the screw mechanism of the utility model, wherein the guide sleeve is composed of an upper guide sleeve 2 and a lower guide sleeve 5 fixedly connected with the upper guide sleeve 2, and the upper guide sleeve The cover 2 is provided with a limit sleeve 3 which is set on the screwdriver head rod 1. The abutment spring 4 is located in the guide sleeve and is set on the screwdriver head rod 1. One end of it leans against the limit sleeve 3, and the other One end leans against the inner end surface of the lower guide sleeve 5, and the magnetic part is an annular magnetic piece 6 clamped at the bottom end surface of the lower guide sleeve 5 by the magnetic sheet fixing plate 7 fixedly connected with the lower guide sleeve 5.

The magnetic suction type screwdriver head device used in the screw driving mechanism of the utility model uses a permanent magnetic sheet, saves the pneumatic adsorption device, simplifies the overall structure, has few parts, does not occupy a large space, and has strong adsorption force , The amount of axial movement is adjusted against the spring, the action is sensitive and reliable, and the manufacturing cost is low.

Description of drawings

Fig. 1 is a schematic structural view of a specific embodiment of the utility model.

Detailed ways

As shown in the figure: 1 is a screwdriver head rod, and the bottom of the screwdriver head rod 1 is integrally connected with a screwdriver head 9, and the screwdriver head 9 is a cross-shaped cutter head matched with the screw. A limit sleeve 3 is set on the screwdriver head rod 1, and the screw fixed connection between the limit sleeve 3 and the screwdriver head rod 1 is used for axial positioning. 2 is the upper guide sleeve that is sleeved on the screwdriver head rod 1, and 5 is the lower guide sleeve that is fixedly connected with the upper guide sleeve 2, and the junction between the upper guide sleeve 2 and the lower guide sleeve 5 is provided with a notch and is fixedly connected with screws. In the inner cavity formed by the upper guide sleeve 2 and the lower guide sleeve 5, the screwdriver head rod 1 is set with a propping spring 4, the upper end of the propping spring 4 is against the limit sleeve 3, and the lower end is against the bottom of the lower guide sleeve 5. On the inside end face, at this moment, the position is limited by the limit sleeve 3, so that the guide sleeve composed of the upper guide sleeve 2 and the lower guide sleeve 5 is always kept at the bottom end of the screwdriver head rod 1. 7 is a magnetic sheet fixing plate, and its middle integral structure is connected with a fastening tube 10 and the inner hole of the lower guide sleeve 5 for fastening connection, and 6 is a ring-shaped permanent magnetic sheet, which is clamped between the magnetic sheet fixing plate 7 and the lower guide sleeve Between the bottom end faces of the guide sleeve 5. An installation process hole 8 is processed on the side of the upper guide sleeve 2 to facilitate the installation of the screw between the limit sleeve 3 and the screwdriver head rod 1 . After assembly, the bottom end of the screwdriver head 9 is flush with the bottom end surface of the magnetic plate fixing plate 7 or slightly retracted, so as not to be exposed.

During work, the screwdriver head rod 1 is installed on the screw machine, and the magnetic sheet 6 is used to attract the screw, so that the top plane of the screw is just attached to the bottom plane of the magnetic sheet fixing plate 7, and the screw end is aligned with the screw hole. Axial pressure is applied by the screwdriver head rod 1, so that the screwdriver head 9 matches the cross groove in the middle of the upper plane of the screw. At this time, the abutment spring 4 is compressed until the screwdriver head 9 enters the cross groove on the top plane of the screw. , the rotation of the screwdriver head rod 1 can achieve the purpose of assembly.
