How it works and how to use it:

As shown in the accompanying drawings 10-11, the following describes the magnetic adsorption and magnetic closing functions of the magnetic mechanism in the bolt loading and unloading device of the present invention:

Magnetic adsorption state:

When the magnet support 4 is located at the end side of the arc-shaped track groove 18 in the counterclockwise direction, the first magnet 12 is located directly above the first magnetic conductive boss 15 , and the second magnet 13 is located directly above the second magnetic conductive boss 16 . , forming a magnetic closure, in a state of magnetic adsorption.

specific:

When the first magnet 12 is located directly above the first magnetic conductive boss 15 and the second magnet 13 is located directly above the second magnetic conductive boss 16 , the protrusions of the first magnetic conductive boss 15 and the second magnetic conductive boss 16 The rising part is in close contact with the working surface of the bolt to be loaded and unloaded; according to the magnetic characteristics of the magnet, the magnetic field line starts from the N pole of the second magnet 13, passes through the second magnetic conductive boss 16 and passes through the working surface of the bolt to be loaded and unloaded. The first magnetic conductive boss 15 returns to the S pole of the first magnet 12 to form a magnetic loop, thereby realizing the adsorption function.

Magnetic off state:

When the magnet support 14 is located at the end side of the arc-shaped track groove 18 in the clockwise direction, the first magnet 12 and the second magnet 13 are not located on the first magnetic conductive boss 15 and the second magnetic conductive boss 16, and are not formed. Magnetically closed, in a magnetically closed state.

specific:

When the first magnet 12 and the second magnet 13 are not on the first magnetically conductive boss 15 and the second magnetically conductive boss 16 , or the first magnet 12 and the second magnet 13 are partially on the second magnetically conductive boss 16 According to the magnetic characteristics of the magnet, the magnetic field line starts from the N pole of the second magnet and returns to the S pole of the first magnet 12 through the second magnetic conducting boss 16, and only a small part of the magnetic field line passes through the to-be-mounted and unloaded The working face of the bolt, thereby realizing the breaking function.

In specific use, first put the annular base on the bolt to be installed and removed, and make the first magnetic conductive boss 15 and the second magnetic conductive boss 16 closely contact with the working surface of the bolt to be installed and removed; then rotate the magnet support 14 counterclockwise to At the end of the arc-shaped track groove, the magnetic adsorption function is realized; then the rotating bar 4 of the upper cover 1 is rotated, and the rotation of the rotating bar 4 drives the first bevel gear 19 to rotate, and the first bevel gear 19 rotates to drive the second bevel gear 23 to rotate , the second bevel gear 23 makes the helical rotation shaft 25 rotate, the rotation of the helical rotation shaft 25 becomes translation through the driven tooth portion 21, the guide portion 22 drives the transmission member to translate, and finally the rubber block 20 is in close contact with the nut of the bolt to be loaded and unloaded. , to achieve the effect of tightening the nut and avoid the common rotation of the screw and the nut; at this time, use a wrench and other tools at the other end of the bolt to carry out the loading and unloading of the screw of the bolt. Due to the tightening effect of the fastener 7 and the magnetic adsorption effect , the user only needs to turn the wrench, and the torque generated by the mounting and dismounting bolts is resisted by the fastening base 2 and the magnetic base 3 .

The bolt loading and unloading device of the utility model utilizes the rotation of the upper cover to drive the fasteners to clamp or loosen the bolts in translation, and the rotation of the magnet support drives the magnets to attract or loosen the components to tighten or loosen the bolts. The structure is simple and the operation is convenient. It is suitable for various types of large bolts and is convenient for bolt loading and unloading, improving work efficiency.

The above-mentioned embodiment is only one of the embodiments that can realize the technical solution of the present invention. The scope of protection of the present invention is not only limited by the present embodiment, but also included in the technical scope disclosed by the present invention. Any Variations, substitutions, and other embodiments will readily occur to those skilled in the art.
