[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Please refer to Figures 1 to 6 , Figure 1 It is a structural schematic diagram of a guide rod of a steel plate magnetic centering device in the prior art; Figure 2 for Figure 1 Section view in AA direction; Figure 3 A schematic structural diagram of a guide rod of a steel plate magnetic centering device provided in an embodiment of the present invention; Figure 4 for Figure 3 Cross-sectional view in the BB direction; Figure 5 A schematic diagram of the structure of a fixed base plate used in an embodiment of the present invention; Figure 6 for Figure 5 Cross-sectional view in CC direction.

[0027] The present invention provides a guide rod of a steel plate magnetic centering device, comprising a frame 1 provided with a mounting hole, a guide rod body 2 connected to the mounting hole, and a flange bottom plate 3 arranged between the frame 1 and the guide rod.

[0028] In the guide rod of the steel plate magnetic centering device, a mounting hole is set through the frame 1, and one of the axial ends of the guide rod body 2 is inserted and positioned in the mounting hole, so that the aforementioned mounting hole is sleeved and fixed on the axial end of the guide rod body 2.

[0029] As for the flange bottom plate 3, it is sleeved on the guide rod body 2, and includes a coaxially distributed large ring body 32 and a small ring body 31. Obviously, the inner diameters of the aforementioned large ring body 32 and the small ring body 31 depend on the diameter of the guide rod body 2. For example, when the guide rod body 2 is a round rod with equal diameters at all axial locations, the inner diameter of the large ring body 32 is equal to the inner diameter of the small ring body 31. It can be seen that for the flange bottom plate 3, the difference in size between the large ring body 32 and the small ring body 31 is specifically reflected in the outer diameters of the large ring body 32 and the small ring body 31. In other words, the outer diameter of the large ring body 32 is greater than the outer diameter of the small ring body 31.

[0030] When the flange bottom plate 3 is sleeved on the guide rod body 2, the small ring body 31 of the flange bottom plate 3 is located between the inner wall of the mounting hole and the rod periphery of the guide rod body 2, and the large ring body 32 of the flange bottom plate 3 is attached to one side of the frame body 1, and the large ring body 32 and the guide rod body 2 are located on the same side of the frame body 1. Based on the above structure, the guide rod provided by the present invention is further provided with a fixed bottom plate 4, and the fixed bottom plate 4 and the large ring body 32 are attached to two opposite sides of the frame body 1 respectively.

[0031] In the guide rod of the steel plate magnetic centering device, the small ring body 31 and the guide rod body 2 are respectively fixedly connected to the fixed base plate 4. For example, a first connection point for achieving a fixed connection can be set between the small ring body 31 and the fixed base plate 4, and a second connection point for achieving a fixed connection can be set between the guide rod body 2 and the fixed base plate 4.

[0032] For the guide rod of the above-mentioned steel plate magnetic centering device, the fixed base plate 4 is connected to the guide rod body 2 and the flange base plate 3 with a small ring body 31 at the same time, so the force between the guide rod body 2 and the flange base plate 3 can be shared through the fixed base plate 4 and transmitted more evenly to the entire axial end of the guide rod body 2, thereby improving the force between the flange base plate 3 and the guide rod body 2, and avoiding the use effect of the guide rod in the steel plate magnetic centering device due to quality defects between the flange base plate 3 and the guide rod body 2. Among them, the force between the guide rod body 2 and the flange base plate 3 mentioned above mainly refers to the force along the radial direction of the flange base plate 3.

[0033] In summary, the guide rod of the steel plate magnetic centering device is additionally provided with a fixed base plate 4, and the fixed base plate 4 is fixedly connected to at least the small ring body 31 of the flange base plate 3 and the end of the guide rod body 2 respectively. Therefore, compared with the existing technology that only maintains the connection relationship between the flange base plate 3 and the guide rod body 2 by fasteners, in the guide rod of the steel plate magnetic centering device provided by the present invention, the force characteristics between the flange base plate 3 and the guide rod body 2 are more reasonable and safe, which is conducive to improving the firmness of the guide rod, avoiding product loosening, and improving the safety of product use.

[0034] The guide rod of the steel plate magnetic centering device provided by the present invention is further described below in conjunction with the accompanying drawings and implementation methods.

[0035] For the guide rod of the above-mentioned steel plate magnetic centering device, the connection between the small ring body 31 and the fixed base plate 4 can be achieved by welding, that is, the axial end of the small ring body 31 can be welded to the inner plate surface of the fixed base plate 4. The inner plate surface of the fixed base plate 4 refers to the plate surface on one side facing the bracket, and conversely, the outer plate surface of the fixed base plate 4 refers to the other side plate surface away from the bracket.

[0036] As for the guide rod body 2, it can be locked to the fixed base plate 4 by a first fastener. For example, the fixed base plate 4 and the guide rod body 2 are both provided with holes for the first fastener to penetrate, and when the small ring body 31 and the fixed base plate 4 are welded and fixed, the hole in the fixed base plate 4 is aligned with the hole in the guide rod body 2, and the first fastener is usually penetrated from the outer plate surface of the fixed base plate 4.

[0037] Usually, in order not to affect the installation and use of the guide rod of the steel plate magnetic centering device, the end of the first fastener close to the fixed base plate 4 can be completely sunk into the fixed base plate 4.

[0038] In combination with the specific structure of the guide rod body 2 and the flange bottom plate 3, the fixed bottom plate 4 is usually set as a circular plate. The circular plate is coaxially distributed with the guide rod body 2. In this case, the first fastener may include a first bolt coaxially distributed with the central axis of the guide rod body 2. In other words, when the circular plate and the guide rod body 2 are fixedly connected by the first bolt, the first bolt penetrates from the center of the circular plate and the central axis of the guide rod body 2 and is positioned and connected.

[0039] In addition, the first fastener may further include two second bolts symmetrically arranged on both sides of the first bolt. Any one of the second bolts is parallel to the first bolt, and the two second bolts are respectively located on two opposite sides of the first bolt in the radial direction. The types of the first bolt and the second bolt, and the spacing between the first bolt and the second bolt can be specifically set according to the radial size of the guide rod body 2.

[0040] In order to better play the role of the fixed bottom plate 4, on the basis of the above structure, the size of the fixed bottom plate 4 is larger than the size of the mounting hole in the frame body 1, so the inner plate surface of the fixed bottom plate 4 completely covers the mounting hole. In the above structure, the fixed bottom plate 4 not only fits and contacts with the end surface of the small ring body 31 and the end of the guide rod body 2, but also fits and contacts with the frame body 1 provided with the mounting hole. Therefore, the fixed bottom plate 4 can also transfer the force between the guide rod body 2 and the flange bottom plate 3 to the frame body 1, further improving the force between the guide rod body 2 and the flange bottom plate 3.

[0041] As for the flange bottom plate 3 and the frame body 1, a fixed connection can be achieved through the large ring body 32 and a plurality of second fasteners inserted in the large ring body 32. Based on the structural characteristics of the flange bottom plate 3 and the assembly relationship between the small ring body 31 and the frame body 1 and the guide rod body 2, the aforementioned plurality of second fasteners can be distributed around the mounting hole in the frame body 1. Among them, any second fastener is inserted from the axial end face of the large ring body 32 and locked in the frame body 1.

[0042] With respect to the above-mentioned multiple second fasteners ringed around the mounting holes, in the guide rod of the steel plate magnetic centering device, the fixed base plate 4 can be arranged in the area surrounded by all the second fasteners, or in other words, the size of the area surrounded by all the second fasteners is larger than the size of the fixed base plate 4. Therefore, any second fastener that penetrates into the large ring body 32 and the frame body 1 will not penetrate into the fixed base plate 4.

[0043] The guide rod of the magnetic centering device for steel plates provided by the present invention is introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
