Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise specified, use of the terms "upper" and "lower" as used herein refers to the definition in the drawing of corresponding figures, and "inner" and "outer" refer to the inner and outer of the profile of corresponding parts. In addition, when the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements, unless otherwise indicated.

The magnetic sleeve is a tool capable of absorbing the bolt or the nut while twisting the bolt or the nut, and parts are prevented from falling off in the assembling process. For example, when assembling a front shock absorber of a vehicle, it is necessary to fix the shock absorber to the vehicle body by using a nut in such a manner that the shock absorber is vertically fixed downward. Because the nut is small in size, the nut is easy to fall into a vehicle body during manual fastening. As shown in fig. 4, in the related art, a magnetic ring 2 'is disposed in a cylinder 1 of a magnetic sleeve, and the magnetic ring 2' is attached to an inner cylinder wall of the cylinder 1. When the magnetic sleeve is used for fastening the nut 6, the magnetic ring 2' is axially abutted against the end part of the nut 6. Because the shock absorber bolt 7 and the magnetic ring 2 ' have a close contact phenomenon in the radial direction (i.e. the horizontal direction in the figure), the bolt 7 and the magnetic ring 2 ' are easy to collide, so that the magnetic ring 2 ' is cracked and damaged.

In order to solve the problems in the related art, as shown in fig. 1 to 3, the present disclosure provides a magnetic sleeve for fastening and assembling a nut 6, which includes a cylinder 1 having a cylinder wall, and a magnetic member 2 for attracting the nut 6 is embedded in a position of the cylinder wall for driving the nut 6 to rotate. Through above-mentioned technical scheme, be used for driving nut 6 pivoted position at telescopic section of thick bamboo wall and be provided with magnetic part 2, can adsorb nut 6, prevent that nut 6 from falling into in the automobile body at the in-process of assembly, and magnetic part 2 is embedded in section of thick bamboo wall. It should be noted here that the magnetic member 2 is embedded in the cylinder wall means that the magnetic member 2 does not protrude from the wall surface of the cylinder wall, i.e. is located outside the nut 6, so that when the sleeve is fastened and removed after the sleeve is assembled with the nut 6, the bolt 7 and the magnetic member 2 do not collide in the radial direction, thereby damaging the magnetic member 2 and prolonging the service life of the magnetic sleeve.

In one embodiment of the present disclosure, as shown in fig. 2, the cylinder wall may be opened with a through hole 3 penetrating in the radial direction, and the magnetic member 2 is disposed in the through hole 3. The through hole 3 can be configured as a cylindrical hole, and the cylindrical through hole 3 has a simple structure and can be conveniently processed by using a drilling tool. Accordingly, the magnetic member 2 may be provided as a magnetic pillar having high strength matching the shape of the through-hole 3. It should be understood that the present disclosure is not limited to the way the magnetic member 2 is embedded in the cylinder wall, and any structure or method capable of embedding the magnetic member 2 in the cylinder wall can be applied to the present disclosure. For example, besides the through hole 3 penetrating in the radial direction, a blind hole may be formed in the radial direction of the cylinder wall, or a buried hole may be reserved when the cylinder 1 is cast, and the magnetic member 2 is buried in the buried hole. The magnetic part 2 is required to be close to the inner side of the cylinder wall of the cylinder body 1 as much as possible no matter arranged in a blind hole or a buried hole, so that the phenomenon that the adsorption force of the magnetic part 2 is weakened due to the fact that the magnetic part is far away from the nut 6 is avoided.

In other embodiments of the present disclosure, the number of the through holes 3 may be multiple, and the through holes are embedded in the wall of the cylinder 1 at intervals. Set up a plurality of through-holes 3 that can embed magnetic part 2, increased the adsorption area between magnetic part 2 and the nut 6, further improved the stability of this disclosure magnetic sleeve when adsorbing nut 6, prevent that magnetic sleeve from leading to nut 6 to deviate from and fall into in the car because of the adsorption affinity of magnetic part 2 is not enough at the during operation.

According to an embodiment of the present disclosure, as shown in fig. 1 to 3, in order to prevent the magnetic member 2 from coming out of the cylinder 1 when the magnetic sleeve of the present disclosure is in operation, a sheath 4 for limiting the outer position of the magnetic member 2 may be sleeved on the outer side of the cylinder 1. Sheath 4 can adopt the nylon materials to make to avoid this disclosure magnetic sleeve during operation to cause the damage to barrel 1 lateral surface. Further, the sheath 4 may be arranged to at least completely cover the magnetic element 2, which saves material while ensuring that the sheath can function to prevent the magnetic element from coming off from the outside. Of course, the sheath 4 may cover the through hole 3 and then extend upward without affecting the normal operation of the magnetic sleeve of the present disclosure.

According to another embodiment of the present disclosure, as shown in fig. 1 to 3, in order to prevent the magnetic member 2 from coming out of the interior of the cylinder 1 when the magnetic sleeve of the present disclosure is in operation, an inner snap ring 5 for limiting the interior of the magnetic member 2 may be attached to the cylinder wall of the cylinder 1. The inner snap ring 5 can be made of aluminum alloy material. The wall of the barrel body 1 can be provided with a clamping groove to accommodate the inner clamping ring 5. Or the inner snap ring 5 is adhered to the inner wall of the cylinder 1. To save materials, a blocking piece can be arranged at each magnetic element 1, and the effect of preventing the magnetic elements 2 from falling off from the inside can also be achieved. Further, the inner snap ring 5 may partially cover the magnetic member 2, so that a portion of the magnetic member 2 is exposed to attract the nut 6. In the present disclosure, the inner snap ring 5 may cover a half portion of the magnetic member 2. Of course, the area of the inner snap ring 5 covering the magnetic element 2 can be reduced as much as possible under the condition that the magnetic element 2 does not fall off from the inside, that is, the exposed area of the magnetic element 2 is increased, so as to improve the adsorption force of the magnetic element 2 to the nut 2.

In one embodiment of the present disclosure, as shown in fig. 1 to 3, the inside of the barrel 1 may be configured as a stepped structure, the nut 6 may be accommodated in a portion of the stepped structure having the largest shaft diameter, and the shaft diameter of the nut 6 is greater than that of the remaining stepped structures, so that the stepped structure may limit the nut 6 such that the nut 6 may only axially move in the portion of the stepped structure having the largest shaft diameter without being separated from the other end of the barrel 1. In order to further limit the axial range of movement of the nut 6 within the cylinder 1 and further make the magnetic sleeve compact, the magnetic member 2 may also be disposed at the portion of the stepped structure where the axial diameter is largest and located laterally to the nut 6. The inner snap ring 5 abuts against a shoulder portion of the portion having the largest axial diameter, so that the magnetic member 2 is shielded from coming off from the inside, and the displacement of the nut 6 in the axial direction can be restricted.

In the present disclosure, the magnetic member 2 may be made of a magnet or other magnetic elements having a capability of attracting the nut, which is not limited in the present disclosure.

This magnetic sleeve is when using, and magnetic part 2 assembles in through-hole 3, and sheath 4 carries out spacing fixed to magnetic part 2 from the outside, prevents that magnetic part 2 from deviating from the outside, and interior snap ring 5 carries out spacing fixed to magnetic part 2 from inside, prevents that magnetic part 2 from deviating from the inside. The nut 6 is sucked into the sleeve. When the nut 6 is tightened vertically downwards, the magnetic sleeve is driven to rotate, for example by means of a pneumatic tool, to drive the nut 6 to tighten on the bolt 7. Therefore, the nut 6 can be effectively prevented from falling off in the vertical operation, the magnetic part 2 is prevented from directly contacting the bolt 7, the magnetic part 2 is prevented from being damaged due to the impact of a tool, and the service life of the magnetic sleeve is prolonged.
