Description

Technical Field

[0001] This utility model relates to the field of bearing cage storage technology, and specifically to a cage placement device. Background Technology

[0002] With the rapid development of fields such as aviation, aerospace, and robotics, the requirements for lightweight components are becoming increasingly stringent. Non-metallic materials for bearing cages have a lower density than metallic materials. Using thin-walled non-metallic cages helps reduce overall weight. The thin-walled design reduces rotational inertia, improving the response speed and efficiency of mechanical systems. Non-metallic materials also possess excellent wear resistance, corrosion resistance, and insulation properties, which can improve the service life and operational reliability of bearings and other components.

[0003] Existing thin-walled bearing cages are prone to tilting or tipping over when stacked in multiple layers during operation or storage, as their wall thickness is mostly around 1mm. Currently, the industry is customizing cylindrical cylinders that match the inner diameter of the cage for each model. The materials can be non-metallic or metallic. There are many new models of such thin-walled cages, and each model requires customization with a long lead time, resulting in low efficiency and idle and wasteful molds.

[0004] Therefore, there is a need to provide a cage placement device to solve the above problems. Utility Model Content

[0005] This invention provides a cage placement device to solve existing problems.

[0006] The cage placement device of this utility model adopts the following technical solution, including:

[0007] The base has at least three support components evenly distributed around its center, and the support components are slidably arranged along the center of the base towards the outer periphery.

[0008] And a magnetic attachment component, located at the bottom of the support component, is used to magnetically attach to the base to fix the position of the support component.

[0009] Preferably, the support assembly includes: a vertically arranged support rod, a slider at the bottom of the support rod, the slider being slidably connected in a groove opened from the center of the base outward, wherein a magnetic suction assembly is disposed at the bottom of the slider.

[0010] Preferably, the support rod is provided with a rubber layer.

[0011] Preferably, the magnetic attraction assembly includes a plurality of magnets, which are evenly distributed in the mounting groove opened at the bottom of the slider.

[0012] Preferably, the bottom surface of the slider is flush with the end face of the magnet.

[0013] Preferably, the flatness of the upper surface of the base is 0.02.

[0014] Preferably, the upper surface of the slider is lower than the upper surface of the base.

[0015] Preferably, chamfers are provided between the two end faces of the base and the outer peripheral face.

[0016] The beneficial effects of this utility model are:

[0017] Multiple support components are slidably mounted on the base. By adjusting the position of the support components on the base, cages of different diameters can be placed. The adjustment is convenient and saves time on mold making. At the same time, the adjusted support components are fixed to the base using magnetic components, that is, using magnetic force instead of traditional mechanical tightening, preventing deformation of the placement device. Compared with the existing device, this utility model replaces the original cylinder with three support components to fix the circle at three points. After adjustment, the size of the circle will not change or deform. The weight is reduced, the space is small, and the placement and use of the cage is convenient, improving processing efficiency and greatly reducing costs. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] An embodiment of the cage placement device of this utility model, such as Figure 1 and Figure 6 As shown, it includes: a base 1 and a magnetic component. At least three support components are evenly distributed around the center of the base 1. The support components are slidably arranged outward from the center of the base 1. The magnetic component is disposed at the bottom of the support component and is used to magnetically attract the base 1 to fix the position of the support component. In this embodiment, the base 1 is made of magnetic material.

[0028] For example, in one specific embodiment, such as Figure 5 As shown, the support assembly includes: a vertically arranged support rod 3, and a slider 2 at the bottom of the support rod 3. Specifically, as shown... Figure 1 and Figure 4 As shown, the top of the slider 2 is provided with a mounting hole 21, the support rod 3 is fixed in the mounting hole 21, and the slider 2 is slidably connected in the groove 11 opened along the center of the base 1 in the outward direction, as shown. Figure 2 As shown, a central hole 12 is provided in the center of the base 1, and one end of the slide groove 11 is connected to the central hole. The magnetic suction component is located at the bottom of the slider 2.

[0029] For example, in one specific embodiment, in order to prevent the support rod 3 from damaging the inner ring of the cage 4, the support rod 3 of this embodiment is provided with a rubber layer.

[0030] For example, in one specific embodiment, such as Figure 3 As shown, the magnetic assembly includes two magnets 22, which are evenly distributed in the mounting grooves opened at the bottom of the slider 2. The magnets 22 are fixed in the mounting grooves by adhesive.

[0031] For example, in one specific embodiment, in order to avoid the magnet 22 affecting the sliding of the slider 2, the bottom surface of the slider 2 is flush with the end face of the magnet 22.

[0032] For example, in one specific embodiment, the flatness of the upper surface of the base 1 is 0.02.

[0033] For example, in one specific embodiment, in order to avoid the slider 2 affecting the cage, the upper surface of the slider 2 is lower than the upper surface of the base 1 in this invention.

[0034] For example, in one specific embodiment, chamfers are provided between the two end faces of the base 1 and the outer peripheral face, in order to prevent stress concentration and deformation, and to facilitate movement and handling.

[0035] Specific working principle

[0036] In use, first place the base 1 on a horizontal platform, and install the slider structure consisting of slider 2 and magnet 22 into the groove 11 of the base 1. Move the three sliders 2 to a position smaller than the inner diameter of the retainer 4, and then fit the thin-walled retainer 4 from above. According to the size of the retainer 4, fine-tune some sliders 3 so that there is a slight gap between the inner diameter of the retainer 4 and the outer circle formed by the three support rods 3. After the adjustment, the slider 2 will be connected to the base 1 by the magnetic attraction of the magnet 22, thus ensuring that the diameter of the outer circle formed by the three support rods 3 remains unchanged. Then, multiple retainers 4 of the same model can be fitted into the outer circle formed by the three support rods 3. Since both the support rod 3 and the non-metallic cage 4 are very light, they can maintain their relative positions during storage and transfer. For cages 4 of different diameters, only the diameter of the circumscribed circle formed by the three support rods 3 needs to be adjusted to accommodate different cages 4. This makes adjustment convenient. After adjustment, the cage is fixed by magnetic force, which will not cause mechanical deformation to the base. This ensures the accuracy of the base 1 and the slider 2 and provides a good storage device for high-precision thin-walled non-metallic cages 4.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
