Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a chamfering device for a sliding bearing. Background Art

[0002] A sliding bearing is a bearing that works under sliding friction. Its function is to support the rotating shaft and reduce friction loss. Chamfering is a process step in bearing design, which helps to release the internal stress of the material during heat treatment, prevent cracks in the material and reduce the possibility of deformation. However, the existing chamfering device of the sliding bearing needs to adjust the position of two grinding wheels when chamfering bearings of different widths so that the grinding wheels are aligned with the edge of the bearing for chamfering. Since the grinding wheels are generally fixed to the base by bolts, the adjustment process is time-consuming and laborious.

[0003] In order to address the above problems, a Chinese patent with the existing announcement number CN218312475U proposes a sliding bearing chamfering device, which can drive two mounting seats to move relative to each other through a bidirectional screw, so that the support seats on the two mounting seats drive the driving motors to approach each other, and then chamfer the bearing through a grinding wheel.

[0004] However, although the above-mentioned sliding bearing chamfering device can adjust the positions of the two grinding wheels by rotating the bidirectional screw to achieve grinding of the sliding bearing, only a single sliding bearing can be installed in the mounting groove of the sliding bearing chamfering device. When there are many sliding bearings that need to be chamfered, the device is not convenient for chamfering multiple sliding bearings at the same time, resulting in the problem of low chamfering efficiency of the sliding bearings. Therefore, the utility model provides a chamfering device for a sliding bearing to meet the demand. Utility Model Content

[0032] like Figures 1 to 4As shown, an embodiment of the utility model provides a chamfering device for a sliding bearing, comprising a base 1, a support plate 7 being fixed to the top thereof by a fixing rod 13, a plurality of rotating shafts 5 being arranged on the top of the support plate 7, the rotating shafts 5 passing through and being rotatably arranged on the support plate 7, a driving assembly 2 for driving the plurality of rotating shafts 5 to rotate being arranged on the base 1, a tray 4 being sleeved on the rotating shaft 5, an adjusting mechanism 12 being arranged on the top of the support plate 7, a plurality of chamfering tools 11 being movably arranged on the adjusting mechanism 12 for contacting with the sliding bearings 8 sleeved on the rotating shaft 5, a pressing block 10 being sleeved on the top of the rotating shaft 5, a plurality of slots 3 being arranged along the length direction of the rotating shaft 5, a limiting assembly 9 for limiting the slots 3 being arranged on the pressing block 10.

[0033] Specifically, by respectively sleeved a plurality of sliding bearings 8 on the rotating shaft 5 and resting on the tray 4, then sleeved a pressure block 10 on the rotating shaft 5 and pressed on the top of the sliding bearing 8, at this time, the card slot 3 is limited by the limiting component 9, thereby realizing the limitation of the sliding bearing 8, and then the plurality of rotating shafts 5 are driven to rotate by the driving component 2, so that the plurality of sliding bearings 8 rotate, and the chamfering tool 11 is driven by the adjusting mechanism 12 to chamfer the sliding bearing 8. The overall operation is simple, and it is convenient to realize the simultaneous chamfering of a plurality of sliding bearings 8, thereby improving the efficiency of chamfering the sliding bearings 8, and solving the problem that only a single sliding bearing can be installed in the mounting groove of the existing sliding bearing chamfering device. When there are many sliding bearings that need to be chamfered, the device is not convenient for realizing the simultaneous chamfering of a plurality of sliding bearings, thereby causing the problem of low chamfering efficiency of the sliding bearings.

[0034] It should be noted that when the sliding bearing 8 stays on the tray 4, the chamfering tool 11 contacts the bottom of the sliding bearing 8. When the rotating shaft 5 drives the sliding bearing 8 to rotate, the adjusting mechanism 12 drives the chamfering tool 11 to move. For details, please refer to the patent with announcement number CN218312475U, which will not be described in detail here. Furthermore, the driving component 2 can be adjusted according to actual conditions. For example, through belt transmission mechanisms, chain sprockets and other mechanisms, multiple rotating shafts 5 can be rotated simultaneously.

[0035] like Figure 1 As shown, in this embodiment, the support disk 7 is a disc-shaped structure, and a plurality of rotating shafts 5 are arranged around the circumference of the support disk 7 .

[0036] like Figure 1 and Figure 2As shown, in this embodiment, the driving assembly 2 includes: a second driven gear 24, which is sleeved on the bottom of the rotating shaft 5, a first driven gear 23, which is sleeved and rotatably connected to the bottom of the fixed rod 13 and meshed with the second driven gear 24, and a motor 21, which is fixed on the base 1. The driving shaft of the motor 21 is sleeved with a driving gear 22 that meshes with the first driven gear 23. Specifically, the driving gear 22 is driven to rotate by the motor 21, and the driving gear 22 drives the first driven gear 23 to rotate, and the first driven gear 23 drives multiple second driven gears 24 to rotate, thereby realizing the rotation of multiple rotating shafts 5.

[0037] like Figure 1 As shown, in this embodiment, the pressing block 10 is penetrated with a through hole 6 that can be sleeved on the rotating shaft 5, and the limiting assembly 9 includes a movable plate 92, which is movably arranged in the pressing block 10, and a movable groove 94 is provided in the pressing block 10 for the movable plate 92 to move. The first end of the movable plate 92 is fixedly connected to a limiting block 91 for limiting the card slot 3, and the limiting block 91 is movably arranged in the movable groove 94 and the through hole 6, a control rod 95, which is fixedly connected to the second end of the movable plate 92, and the end of the control rod 95 away from the movable plate 92 extends to the outside of the pressing block 10, and a spring 93 is sleeved on the control rod 95 and located in the movable groove 94, and the limiting block 91 is directly opposite to the through hole 6. One end of the block 10 has an inclined surface for limiting the slot 3. Specifically, when the pressure block 10 is sleeved on the rotating shaft 5 and moves toward the sliding bearing 8, the inclined surface of the limit block 91 is pushed into the movable slot 94 by the rotating shaft 5 and squeezes the spring 93. When the limit block 91 corresponds to the slot 3, the spring 93 pushes the limit block 91 out and limits the slot 3. When the pressure block 10 needs to be taken out, the movable plate 92 is pulled by the control rod 95 to make the limit block 91 move into the movable slot 94, thereby releasing the limit on the slot 3. At this time, the pressure block 10 can be taken out along the rotating shaft 5. The overall operation is simple, and the sliding bearing 8 can be quickly limited and disassembled.

[0038] Working principle:

[0039] By respectively sleeved a plurality of sliding bearings 8 on the rotating shaft 5 and resting them on the tray 4, and then sleeved the pressing block 10 on the rotating shaft 5 and pressed on the top of the sliding bearing 8, when the pressing block 10 is sleeved on the rotating shaft 5 and moves toward the sliding bearing 8, the inclined surface of the limit block 91 is pushed into the movable groove 94 by the rotating shaft 5, and the spring 93 is squeezed, and when the limit block 91 corresponds to the card slot 3, the spring 93 pushes the limit block 91 out and limits the card slot 3, thereby limiting the sliding bearing 8, and then the driving gear 22 is driven to rotate by the motor 21, and the driving gear 22 drives the first driven gear 23 to rotate, and the first driven gear 23 is driven to rotate. The moving gear 23 drives multiple second driven gears 24 to rotate, thereby realizing the rotation of multiple rotating shafts 5, so that multiple sliding bearings 8 rotate, and the chamfering tool 11 is driven by the adjustment mechanism 12 to chamfer the sliding bearings 8. The overall operation is simple, which is convenient for realizing simultaneous chamfering of multiple sliding bearings 8, and improves the efficiency of chamfering the sliding bearings 8. It solves the problem that only a single sliding bearing can be installed in the mounting groove of the existing sliding bearing chamfering device. When there are many sliding bearings that need to be chamfered, the device is not convenient for realizing simultaneous chamfering of multiple sliding bearings, thereby causing the problem of low chamfering efficiency of the sliding bearings.
