Abstract
An expansion screw belongs to the field of equipment; the problem of current screw can not automatic equipment is solved. The center of the bowl-shaped bottom support (6) is provided with one end of a shaft (7), and the other end of the shaft is connected with the center of a tray (9); the periphery of the shaft is surrounded with a columnar air bag (8); two to four concave iron sheets (4) are arranged around the columnar air bag at equal intervals, and the back of each concave iron sheet is provided with a thread (3); the connecting part of the funnel center and the tray is provided with a hole, and an air nozzle (1) is connected to the columnar air bag through the hole at the connecting part of the funnel and the tray. The device is used for various industries and carries out automatic assembly or maintenance.
Description
Technical Field
An expansion screw belongs to the field of equipment.
Background
The known screw nail is troublesome to mount or take out, and is not time-saving and labor-saving. And the screws cannot be automatically assembled and disassembled.
Disclosure of Invention
The expansion screw is time-saving and labor-saving in use, and can be used for assembling and disassembling screws in a full-automatic industry.
The invention is that the center of the bowl-shaped bottom support (6) is provided with one end of a shaft (7), and the other end of the shaft is connected with the center of a tray (9); the tray has an edge; the periphery of the shaft is surrounded with a columnar air bag (8); two to four concave iron sheets (4) are arranged around the columnar air bag at equal intervals, and the back of each concave iron sheet is provided with a thread (3); one end of the concave iron sheet is arranged in the edge of the bottom support, and the other end of the concave iron sheet is arranged in the edge of the tray; one point outside the central point of the near tray is connected with a funnel (2); a hole is formed at the joint of the funnel center and the tray, and the air bag inside can be seen through the hole; an air tap (1) is connected to the columnar air bag through a hole at the connection part of the funnel and the tray. The concave iron sheet of the screw is smaller than the edge of the bottom support and the edge of the tray.
According to the working principle, when two objects are connected, holes need to be drilled on the two objects and are slightly larger than the screw nails, and threads need to be arranged in the holes. When in use, the holes of the two objects are opposite and pressed. When high-pressure air or water is supplied, the columnar air bag is inflated or filled with water through the air tap. The balloon is inflated. So that the air bag pushes the iron sheet to press the hole wall. Thus, the installation can be automated. (manipulator removal when deflating, or manipulator insertion inflation)
Due to the adoption of the design, the installation and the maintenance of the two objects can be carried out automatically.
