[ detailed description ] of the invention
In order to further describe the technical means adopted by the present invention and the effects thereof, the following detailed description is made with reference to a preferred embodiment of the present invention and the accompanying drawings.
Referring to fig. 1 to 7, fig. 1 is an exploded view of a magnetic sleeve for pressing nuts. Fig. 6 is a schematic structural view of a magnetic sleeve for nut pressing. Fig. 7 shows a cross-sectional view of a magnetic sleeve for nut pressing. The invention provides a magnetic sleeve for nut pressing, which comprises the following components:
first fixing member 1, first fixing member 1 includes first fixing plate 101 and columnar portion 102 extending from the bottom surface of first fixing plate 101, and magnetic member 2 is provided in columnar portion 102.
Referring to fig. 2 and 3, the sliding member 3 has a first through hole 301, and the sliding member 3 is slidably sleeved on the column portion 102 through the first through hole 301.
The first spring 4 is sleeved on the columnar portion 102, and the first spring 4 abuts against the first fixing plate 101 and the sliding piece 3.
Referring to fig. 4 and 5, the second fixing member 5 is fixed to the bottom surface of the first fixing plate 101, the second fixing member 5 is provided with a second through hole 501 adapted to accommodate the sliding member 3 sliding along the column portion 102, and both the sliding member 3 and the first spring 4 are located in the second through hole 501. The second fixing member 5 has a cylindrical shape, the second through hole 501 is a circular through hole and is coaxial with the second fixing member 5, and the sliding member 3 has a cylindrical shape matched with the second through hole 501.
The end of the second through hole 501, which is far away from the first fixing plate 101, is further provided with a tightening opening 502. The tightening port 502 is annular, the outer circumference of the tightening port 502 is integrally connected with the inner wall of the second through hole 501, and the diameter of the inner circumference of the tightening port 502 is smaller than the diameter of the slider 3. The columnar portion 102 protrudes from the inner circumference of the tightening aperture 502. The tightening opening 502 is a stopper capable of preventing the sliding member 3 from passing therethrough, and serves as a stopper for the sliding member 3.
The outer wall of the second fixing piece 5 also extends out to form a connecting portion 503, the connecting portion 503 is located at one end, close to the first fixing plate 101, of the second fixing piece 5, and the connecting portion 503 is fixedly connected to the bottom surface of the first fixing plate 101.
Two spacing posts 302 are also stretched out to the one end of slider 3 that is kept away from first fixed plate 101, and the length direction of spacing post 302 is on a parallel with the axial of column portion 102, and two spacing posts 302 are relative to set up, and column portion 102 is located between two spacing posts 302. Two notches 5021 are further formed in the tightening opening 502, the notches 5021 correspond to the limiting columns 302 one by one, and the limiting columns 302 extend out of the corresponding notches 5021.
A limiting groove 303 is recessed in one surface of the limiting post 302 facing the columnar portion 102, and the limiting groove 303 extends to an end portion penetrating through the limiting post 302 along the length direction of the limiting post 302. The limiting groove 303 comprises two limiting surfaces 3031, the two limiting surfaces 3031 form an included angle of 120 degrees, and the limiting surfaces 3031 are parallel to the axis of the columnar portion 102.
Referring to fig. 8 and 9, fig. 8 is a schematic diagram illustrating a use state of a magnetic sleeve for nut pressing. Fig. 9 shows a schematic structural view of a hexagonal nut and a hexagonal hole. Since the hexagonal nut 8 has six sides, the included angle formed by every two adjacent sides is 120 degrees, and the sides of each hexagonal nut 8 form six included angles. Therefore, when the side angle of the hexagonal nut 8 is located in the limiting groove 303, the limiting groove 303 plays a limiting role on the hexagonal nut 8, so that the hexagonal nut 8 cannot rotate relative to the sliding member 3.
It should be noted that the number of the limiting posts 302 may also be plural (e.g., three, four, six, etc.), and the limiting posts 302 are distributed around the columnar portion 102. The tightening opening 502 is further provided with a plurality of notches 5021, the notches 5021 are in one-to-one correspondence with the limiting columns 302, and the limiting columns 302 extend out of the corresponding notches 5021. The limit groove 303 on each limit post 302 corresponds to the side included angle of one hexagonal nut 8.
When the spring pushes the slider 3 against the tightening opening 502, the end of the columnar portion 102 is closer to the first fixing plate 101 than the end of the stopper column 302.
The use process of the magnetic sleeve for nut pressing is as follows:
when the screw is taken, the two limiting grooves 303 are respectively aligned with the two side angles of the hexagonal nut 8 to be taken, and the magnetic sleeve is moved to the hexagonal nut 8, so that the side angles of the hexagonal nut 8 slide into the corresponding limiting grooves 303. Then, the magnetic sleeve is continuously pressed, so that the end of the limiting column 302 abuts against the tabletop on which the hexagonal nut 8 to be taken is placed, the first spring 4 is compressed, the sliding piece 3 drives the limiting column 302 to retract, the columnar portion 102 is close to the hexagonal nut 8, and after the columnar portion 102 abuts against the hexagonal nut 8, the hexagonal nut 8 is sucked at the end of the columnar portion 102 under the action of the magnetic piece 2. After the magnetic sleeve is taken off, the first spring 4 is reset, at this time, the hexagonal nut 8 is magnetically attracted to the end of the columnar portion 102, and the side included angle of the hexagonal nut is located in the limiting groove 303, so that an operator can adjust the angle of the hexagonal nut 8 by adjusting the angle of the magnetic sleeve.
When the screw is pressed, the hexagonal nut 8 is adjusted to correspond to the hexagonal hole 9 of the product by rotating the magnetic sleeve, the magnetic sleeve is pressed, the first spring 4 is compressed, the sliding piece 3 drives the limiting column 302 to retract, the columnar portion 102 is close to the hexagonal nut 8, and the columnar portion 102 abuts against the hexagonal nut 8 to press the hexagonal nut into the hexagonal hole 9. Since the fastening force of the hexagonal nut 8 and the hexagonal hole 9 is greater than the attractive force of the magnetic member 2 and the hexagonal nut 8, the columnar portion 102 is disengaged from the hexagonal nut 8 and the hexagonal nut 8 remains in the hexagonal hole 9 after the magnetic sleeve is removed.
The magnetic sleeve for nut pressing can absorb nuts more quickly and can press the nuts into the corresponding mounting holes quickly.
Referring to fig. 7, in this embodiment, the magnetic member 2 is disposed in the column portion 102 in the following specific manner:
the magnetic sleeve for nut pressing further comprises a second spring 6 and a second fixing plate 7. The column part 102 is integrally connected with the first fixing plate 101, a blind hole 103 is recessed in the top surface of the first fixing plate 101, and the blind hole 103 extends into the column part 102. The second fixing plate 7 is fixed to the top surface of the first fixing plate 101. The magnetic member 2 is a cylindrical magnet, the cylindrical magnet and the second spring 6 are both positioned in the blind hole 103, and the second spring 6 is propped against between the cylindrical magnet and the second fixing plate 7. The magnetic member 2 is not limited to one, and may be provided in plural.
The second spring 6 is used for pushing the cylindrical magnet against the bottom surface of the blind hole 103, so as to limit the position of the cylindrical magnet to be closer to the end of the cylindrical portion 102, so that the adsorption force of the end of the cylindrical portion 102 to the hexagonal nut 8 is stronger.
It should be noted that the present invention is not limited to the above embodiments, and any simple modification, equivalent variation and modification of the above embodiments by those skilled in the art based on the technical solutions of the present invention fall within the scope of the present invention.
