Description

Technical Field

[0001] This utility model belongs to the field of bearing ring grinding technology, and specifically relates to a rapid grinding device for bearing rings. Background Technology

[0002] Bearing rings are ring-shaped parts of radial rolling bearings with one or more raceways. Bearings are precision mechanical components that convert sliding friction between a rotating shaft and its housing into rolling friction, thereby reducing friction loss. During the manufacturing process of bearings, grinding equipment is often used to grind the surface of the bearing rings.

[0003] When grinding bearing rings, many small enterprises still use manual grinding because large-scale production lines are expensive. The bearing rings are fixed by a fixture in the equipment, and then the surface of the fixed bearing rings is ground by a hand-held grinder.

[0004] However, when using a clamp to fix the bearing race, a single clamp can usually only hold a small number of bearing race sizes. When the size of the bearing race changes, the clamp needs to be changed. Utility Model Content

[0030] like Figure 1-4As shown, a bearing ring rapid grinding device includes a worktable 1. A grinding mechanism 2, a clamping mechanism 3, and a cooling mechanism 4 are sequentially mounted and connected on the upper side of the worktable 1. A water collection groove is provided below the clamping mechanism 3 on the worktable 1. The clamping mechanism 3 includes two support frames 31. A bidirectional translation mechanism 5 is mounted and connected to one side of the lower part of the support frame 31. A U-shaped fixed clamping plate 32 is rotatably connected to the upper part of the support frame 31. The openings of the fixed clamping plate 32 are arranged opposite to each other. An adjusting plate 33 is provided on one side of the fixed clamping plate 32. An adjusting component 34 for changing the height of the adjusting plate 33 is provided inside the fixed clamping plate 32. A limit block 35 is fixedly connected to the lower side of the two adjusting plates 33 that are close to each other.

[0031] In this embodiment, the grinding mechanism 2 is used to grind the bearing. The grinding mechanism 2 is assembled with the worktable 1. The grinding mechanism 2 includes a grinding machine and a control box. A connecting line connects the grinding machine and the control box. The operator controls the movement of the grinding machine to grind various parts of the bearing. The cooling mechanism 4 is used to cool the grinding mechanism and the bearing ring body during the grinding process, thereby effectively preventing damage caused by high temperature. The bidirectional translation mechanism 5 is used to move the support frame 31, so that the distance between the two support frames 31 can be adjusted according to the size of the bearing to clamp bearings of different sizes. The upper and lower sides of the bearing are located between the fixed clamping plates 32. The adjusting plate 33 is used to cooperate with the lower side of the fixed clamping plate 32 to clamp the bearing. The side of the limiting block 35 contacts the inner ring of the bearing to restrict the bearing at multiple angles. The fixed clamping plate 32 is rotatably connected to the support frame 31. A rotating component is provided on one side of the support frame 31 to control the rotation of the fixed clamping plate 32, so that the bearing is located at different angles, which facilitates the grinding of the bearing.

[0032] Reference Figure 3 The bidirectional translation mechanism 5 includes a double-ended screw 51, with support frames 31 threadedly connected to both ends of the double-ended screw 51. One end of the double-ended screw 51 is connected to a first motor 52. In this embodiment, when the double-ended screw 51 rotates, it drives the two support frames 31 to move, thereby adjusting the distance between the two support frames 31, so that the fixed clamping plate 32 can clamp bearings of different sizes.

[0033] Reference Figure 4The double-ended screw 51 has mounting blocks 53 rotatably connected to both ends. A right-angled protective plate 54 is fixedly connected to the mounting blocks 53 on the outer side of the double-ended screw 51. Two mounting blocks 53 are fixedly connected to a baffle plate 55 on the inner side of the double-ended screw 51. The support frame 31 has a slot for sliding connection with the baffle plate 55. In this embodiment, the mounting blocks 53 are used to install the double-ended screw 51, and the protective plate 54 is used to shield the outer and upper sides of the double-ended screw 51 to prevent grinding debris from affecting it. The baffle plate 55 is located on the inner side of the double-ended screw 51, and slides relative to the baffle plate 55 when the support frame 31 slides.

[0034] Reference Figure 4 The adjusting component 34 is a screw, with its lower and upper ends rotatably connected to the fixed clamping plate 32. The upper end of the screw is located outside the fixed clamping plate 32. The adjusting plate 33 is threadedly connected to the screw, and its side is slidably connected to the fixed clamping plate 32. In this embodiment, the screw is rotatably connected to the fixed clamping plate 32. By rotating the screw, the adjusting plate 33 is threadedly connected to it. When the screw rotates, the adjusting plate 33 can move up and down, thereby clamping the bearing.

[0035] Reference Figure 2 The support frame 31 is equipped with a second motor 36 that is drively connected to the fixed clamping plate 32. In this embodiment, the second motor 36 is used to drive the fixed clamping plate 32 to rotate, thereby enabling the bearing to rotate at different angles.

[0036] Reference Figure 2 A water storage tank 11 is connected to the lower side of the workbench 1. A filter frame 12 is assembled and connected to the lower side of the water collection tank 11. An outlet of the filter frame 12 is provided on one side of the water storage tank 11, and a frame door 13 is provided at the outlet of the filter frame 12. In this embodiment, the water storage tank 11 is used to collect cooled water, and the filter frame 12 is used to collect impurities that may be present in the water, preventing impurities from entering the water storage tank 11. The filter frame 12 can be removed from the outlet of the water storage tank 11, and the frame door 13 can be removed and installed, thereby facilitating the removal of the filter frame 12.

[0037] Reference Figure 1 The cooling mechanism 4 includes a water tank, water pipes, and spray heads. The water pipes are connected to a water pump, and the spray heads are located above the clamping mechanism 3. In this embodiment, the cooling mechanism 4 is used to spray water to cool the bearing and the working parts of the grinding mechanism. The connecting plate connected to the spray head is connected to the support frame 31 on both sides, so that the spray head is located directly above the bearing. After the coolant is sprayed from the spray head, it flows into the water storage tank 11.

[0038] Reference Figure 1Two water outlet pipes 14 are provided on the lower side of the filter frame 12. One water outlet pipe 14 is connected to the water tank of the cooling mechanism 4, and the other water outlet pipe 14 is equipped with a valve 15. In this embodiment, one water outlet pipe 14 is used to discharge the used water in the water storage tank 11, and the valve 15 is used to block and control the discharge of water. The operator can choose to reuse the water or discharge it according to the condition of the coolant.
