Description

Technical Field

[0001] This application relates to the field of bearing assembly technology, and in particular to a fixture for stainless steel bearings. Background Technology

[0002] Bearings are key components that provide support and reduce friction during mechanical transmission. They typically consist of an inner ring, an outer ring, rolling elements, and a cage. The inner ring fits tightly to the shaft, while the outer ring is connected to the bearing housing. The rolling elements can be of various shapes, such as balls, cylindrical rollers, or tapered rollers, and they roll between the inner and outer rings, greatly reducing frictional resistance during rotation and enabling the mechanical system to operate smoothly and efficiently.

[0003] Existing fixtures mostly adopt a fixed structure, which cannot flexibly adapt to bearing inner and outer rings of different sizes, resulting in easy displacement or misalignment during press-fitting, affecting the accuracy of the finished product. Summary of the Invention

[0004] The purpose of this application is to provide a stainless steel bearing clamp to solve the above problems. It adopts a modular and detachable structure, which can be quickly switched to support multiple bearing models, facilitates disassembly and replacement, and reduces maintenance costs.

[0005] This application achieves the above objectives through the following technical solutions:

[0006] A clamp for a stainless steel bearing includes: a housing providing support, with a pressure-applying structure at the top for press-fitting the bearing ring; a replacement plate detachably connected to the top of the housing, having a circular opening in its center; an outer ring positioning ring positioned along the circular opening in the center of the replacement plate for positioning the bearing outer ring; an outer ring support ring positioned inside the outer ring positioning ring for supporting the bearing outer ring; an inner ring positioning ring coaxially arranged with the outer ring positioning ring, adapted to the inner side of the bearing inner ring for insertion and positioning, and connected to an elastic structure for raising the bearing inner ring to be assembled; an inner ring support ring fixedly positioned at the bottom edge of the inner ring positioning ring for supporting the bearing inner ring; and a limiting sleeve connected to the elastic structure, configured to adjust its height to limit the descent stroke of the inner ring positioning ring.

[0007] In some embodiments, the elastic structure includes: a vertical cylinder extending vertically along its length; a prism, the vertical cylinder having an insertion hole adapted to the prism to enable the prism to move vertically up and down along the insertion hole, an inner positioning ring being detachably connected to the prism; and a spring disposed within the insertion hole and at the bottom of the prism to enable the prism to be elastically pushed.

[0008] In some embodiments, the pressure-applying structure includes: a stand, the bottom of which is fixedly connected to the top of the housing; a telescopic cylinder, fixedly mounted on the top of the stand and extending axially in the vertical direction; and a pressure plate, fixedly connected to the output end of the telescopic cylinder and positioned above the inner positioning ring.

[0009] In some embodiments, the top of the housing is provided with an opening adapted to accommodate a replacement plate, and the edge of the opening is provided with a flange to accommodate the replacement plate.

[0010] In some embodiments, the elastic structure further includes a limiting rod, which is coaxial with the vertical tube and fixedly disposed inside the vertical tube, and the prism is provided with a sliding hole adapted to the limiting rod; a spring is sleeved on the limiting rod.

[0011] In some embodiments, a reinforcing rib is fixedly connected to the outer wall of the vertical cylinder, and the reinforcing rib is also fixedly connected to the shell.

[0012] In some embodiments, the outer wall of the vertical cylinder has external threads, and the inner wall of the limiting cylinder has internal threads, and the two are screwed together to adjust the height of the limiting cylinder.

[0013] In some embodiments, a buffer layer is provided at the bottom of the pressure plate.

[0014] In some embodiments, the prism and the inner locating ring are connected by fasteners.

[0015] Compared to existing technologies, this application adopts a modular and detachable structure. The replacement plate is a detachable flat plate structure with a central circular opening to accommodate the outer and inner locating rings. By replacing the locating rings and support rings of different diameters, it can be quickly switched to support various bearing models. The flanged design enhances the stability of the replacement plate, preventing shaking when embedded in the housing and ensuring positioning accuracy during press-fitting. The fasteners are flexibly connected: the inner locating ring and the prism are connected by screws / bolts, which facilitates disassembly and replacement and reduces maintenance costs.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0025] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0026] like Figure 1-4 As shown, a clamp for a stainless steel bearing includes: a housing 1 that provides support, with a pressure structure on the top of the housing 1 for pressing the bearing ring for press fitting; the housing 1 is a box structure to provide stable support; a replacement plate 2 that is detachably connected to the top of the housing 1, with a circular opening in its middle; the replacement plate 2 is a flat plate structure that provides support; an outer ring positioning ring 4 that is positioned along the circular opening in the middle of the replacement plate 2 to position the outer ring of the bearing; the outer ring positioning ring 4 is coaxial with the circular opening and is fixedly connected to the replacement plate 2 along the circular opening; and an outer ring support ring 15 that is disposed inside the outer ring positioning ring 4 to support the outer ring of the bearing; the center of the outer ring support ring 15 has space to avoid the inner ring positioning ring 8, allowing the inner ring positioning ring 8 to pass through; the protrusion of the outer ring support ring 15 is equal to the wall thickness of the bearing ring to stably support the bearing ring.

[0027] like Figure 2As shown, the inner ring positioning ring 8 is coaxially arranged with the outer ring positioning ring 4, and is adapted to the inner side of the bearing inner ring so that it can be inserted into the bearing inner ring for positioning. It is connected to an elastic structure that can raise the bearing inner ring to be assembled. The inner ring positioning ring 8 is cylindrical and is adapted to the inner diameter of the bearing inner ring so that it can be inserted into the bearing inner ring to achieve positioning. The inner ring support ring 16 is fixedly set at the bottom edge of the inner ring positioning ring 8 to support the bearing inner ring. The thickness of the inner ring support ring 16 is the same as the wall thickness of the bearing inner ring to stably support the bearing inner ring. The limiting cylinder 6 is connected to the elastic structure and is configured to adjust its height to limit the downward stroke of the inner ring positioning ring 8. The elastic structure is located below the inner ring positioning ring 8. The limiting cylinder 6 is connected to the elastic structure. When the end of the elastic structure carries the inner ring positioning ring 8 downward, the inner ring positioning ring 8 contacts the limiting cylinder 6 to prevent it from falling excessively, so that the bearing inner ring on the inner ring support ring 16 is just matched with the bearing outer ring.

[0028] like Figure 2 As shown, in some embodiments, the elastic structure includes: a vertical cylinder 5, whose length direction extends vertically, and the vertical cylinder 5 is capable of bearing the lifting and lowering of the prism 7; the prism 7, the vertical cylinder 5 is constructed with an insertion hole adapted to the prism 7 so that the prism 7 can be vertically lifted and lowered along the insertion hole, the inner ring positioning ring 8 is detachably connected to the prism 7, the columnar structure of the prism 7 prevents the prism 7 from rotating on the inner ring positioning ring 8 so as to make the prism 7 rise and fall stably, the inner ring positioning ring 8 is detachable and replaceable, matching the detachable replacement of the replacement plate 2, and different diameter inner ring positioning ring 8, inner ring support ring 16, outer ring positioning ring 4 and outer ring support ring 15 can be replaced to adapt to bearings of different diameters; a spring 9, which is disposed in the insertion hole and located at the bottom of the prism 7 so as to be able to elastically push the prism 7, the spring 9 can be compressed by the descending prism 7, and can push the prism 7 to return to its original position after the pressure is released.

[0029] like Figure 1 As shown, in some embodiments, the pressure-applying structure includes: a stand 12, the bottom of which is fixedly connected to the top of the housing 1; a telescopic cylinder 13, which is fixedly installed on the top of the stand 12 and extends axially in the vertical direction. The telescopic cylinder 13 is prior art, and in some embodiments, the telescopic cylinder 13 can be electrically, hydraulically, or pneumatically driven; and a pressure plate 14, which is fixedly connected to the output end of the telescopic cylinder 13 and is located above the inner ring positioning ring 8. The pressure plate 14 moves up and down with the output end of the telescopic cylinder 13 to apply pressure to the inner ring of the bearing, so that the inner ring of the bearing is assembled inside the outer ring of the bearing.

[0030] like Figure 3 As shown, in some embodiments, the top of the housing 1 is provided with an opening adapted to accommodate the replacement plate 2, and the edge of the opening is provided with a flange 3 to support the replacement plate 2. The replacement plate 2 can be embedded inside the opening by the support of the flange 3, so as to position the replacement plate 2 and prevent the replacement plate 2 from shaking.

[0031] like Figure 2 As shown, in some embodiments, the elastic structure also includes a limiting rod 10, which is coaxial with the vertical tube 5 and fixedly installed inside the vertical tube 5. The prism 7 is provided with a sliding hole adapted to the limiting rod 10. The spring 9 is sleeved on the limiting rod 10, and the limiting rod 10 can guide the spring 9 to maintain linear movement when it pushes the prism 7 to rise after compression and recovery of elasticity.

[0032] like Figure 1 As shown, in some embodiments, a reinforcing rib plate 17 is fixedly connected to the outer wall of the vertical cylinder 5, and the reinforcing rib plate 17 is also fixedly connected to the shell 1. Connecting the vertical cylinder 5 to the shell 1 through the reinforcing rib plate 17 can provide stability.

[0033] In some embodiments, the outer wall of the vertical cylinder 5 is provided with external threads, and the inner wall of the limiting cylinder 6 is provided with internal threads. The two are screwed together to adjust the height of the limiting cylinder 6. Both the vertical cylinder 5 and the limiting cylinder 6 are cylindrical so that the outer wall of the vertical cylinder 5 and the inner wall of the limiting cylinder 6 can be provided with threads so that the two can be screwed together. In this way, turning the limiting cylinder 6 can adjust its height on the vertical cylinder 5, so that the height of the travel of the inner ring positioning ring 8 can be adjusted according to different bearings.

[0034] In some embodiments, a buffer layer is provided at the bottom of the pressure plate 14 to cushion the bearing when it comes into contact with it, thus preventing damage to the bearing.

[0035] In some embodiments, the prism 7 and the inner ring positioning ring 8 are connected by a fastener 11. In some embodiments, the fastener 11 is a screw or bolt that passes through the center of the inner ring positioning ring 8 and is screwed to the top of the prism 7, which can fasten the inner ring positioning ring 8 and facilitate disassembly and assembly.

[0036] In the above structure, the outer ring of the bearing is placed on the outer ring support ring 15 inside the outer ring positioning ring 4, and the outer ring support ring 15 supports the outer ring of the bearing. The inner ring of the bearing is placed on the inner ring support ring 16. The inner ring positioning ring 8 is inserted into the inner side of the inner ring of the bearing for positioning. After completion, the telescopic cylinder 13 is activated to drive the pressure plate 14 to descend. After contacting the inner ring of the bearing, the pressure plate continues to descend and the inner ring is compressed by the prism 7. When the inner ring of the bearing descends to the outer ring of the bearing, the two are pressed together. Then the telescopic cylinder 13 is activated to retract and reset, and the pressed bearing is removed for continued pressing. The compressed spring 9 pushes the prism 7 to rise, so that the inner ring positioning ring 8 and the inner ring support ring 16 rise to return to the initial state, which facilitates the continued pressing of the bearing.
