Description

Technical Field

[0001] The invention relates to a device for closing a nail sleeve for controlling a broken-neck groove threaded nail extraction, and belongs to the technical field of manufacturing mechanical processing parts. Background Art

[0002] At present, controllable broken neck groove threaded screws are widely used in the aerospace field and mechanical equipment and electronic equipment, and the demand is large. This type of product is produced frequently and in large quantities.

[0003] Traditionally, the closed part of the controlled broken neck groove threaded nail sleeve, such as Figure 1 As shown, the product is closed multiple times through two or three-petal closing blocks to meet product requirements. This processing method has low processing efficiency, unstable closing outer circle size, and ugly closing outer circle shape. Summary of the invention

[0004] The present invention aims to solve the technical problems that the prior art uses two-petal or three-petal closing blocks to close the product multiple times to meet product requirements, and this processing method has low processing efficiency, unstable closing outer circle size, and ugly closing outer circle shape.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A device for closing a screw sleeve for controlling a broken neck groove thread, comprising a driving wheel, a clamping ring, a driven wheel, a transmission shaft, a closing wheel, a copper bushing, a distance-adjusting pad, a positioning plate, and a hexagon socket screw; The outer side of the driving wheel is wrapped and connected by three snap rings, and there is no tooth meshing between the driving wheel and the snap rings; The clamping ring is connected to three driven wheels, which are respectively connected to three transmission shafts, and three closing wheels are respectively connected to the three transmission shafts; copper bushings are installed between the driven wheels and the closing wheels on the transmission shafts; The driving shaft, the distance adjusting pad and the positioning plate are connected by hexagon socket screws.

[0006] The beneficial effects of adopting the above technical solution are: The invention is easy to use and has low requirements on processing personnel; it has high closing efficiency and reduces production costs; it has stable and reliable processing and improves product production quality; it has a simple structure and is easy to disassemble and replace parts.

[0012] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0013] A device for closing a screw sleeve for controlling a broken neck groove, comprising a driving wheel 1, a clamping ring 2, a driven wheel 3, a transmission shaft 4, a closing wheel 5, a copper bushing 6, a distance-adjusting pad 7, a positioning plate 8, and a hexagon socket screw 9; The outer side of the driving wheel 1 is wrapped and connected by three snap rings 2, and there is no tooth meshing between the driving wheel 1 and the snap rings 2; The clamp ring 2 is connected to three driven wheels 3, which are respectively connected to three transmission shafts 4, and three closing wheels 5 are respectively connected to the three transmission shafts 4; copper bushings 6 are installed between the driven wheels 3 and the closing wheels 5 on the transmission shafts 4; The driving shaft 1, the distance adjusting pad 7 and the positioning plate 8 are connected by the hexagon socket screw 9 to locate the position of the closing wheel.

[0014] The working principle of the present invention is as follows: a threaded nail 10 is placed in a nail sleeve closing device, the driving shaft 1 starts to rotate counterclockwise, the snap ring 2 drives the driven wheel 3 to slowly shrink inward, as the driving shaft 1 rotates, the snap ring 2 does not rotate, the driven wheel 3 rotates along the axis of the transmission shaft 4, and moves in the direction of compression at the same time, as the driven wheel 3, the transmission shaft 4, and the closing wheel 5 are rigidly connected, the closing wheel 5 rotates along the transmission shaft 4 and moves in the direction of compression, the nail sleeve of the threaded nail 10 receives the compression pressure of the closing wheel 5, the nail sleeve starts to rotate and is compressed in the direction of compression, and reaches the following Figure 1 After the closing size is reached, the clamping ring 2 stops shrinking inwards and gradually returns to its original state, and the nail sleeve is closed.
