[0001] This utility model relates to the field of bearing ring processing technology, and in particular to a bearing ring outer diameter grinding platform. Background Technology

[0002] A bearing ring outer diameter grinding platform is a specialized piece of equipment used for grinding the outer diameter of bearing rings. This equipment can efficiently improve the roundness and geometric accuracy of the workpiece surface. The design and operation of the grinding platform are crucial to ensuring the quality of the bearing rings. The working principle of the grinding platform is based on centerless grinding technology. It uses specially designed grinding wheels to precisely grind the bearing rings. The characteristics of the grinding platform include high efficiency, high precision, and good machining stability. The structure of a bearing ring outer diameter grinding platform generally includes a grinding machine, grinding wheel, fixtures, and other auxiliary mechanisms.

[0003] Bearings come in various sizes and specifications. In the existing technology, most grinding machines for grinding the outer diameter of bearing rings are fixed structures, which cannot be adapted to the use of bearings of different specifications at the same time. If different specifications of bearings need to be ground, the corresponding grinding machine needs to be changed, which is time-consuming and labor-intensive and reduces production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bearing ring outer diameter grinding platform, which aims to improve the problem of reduced production efficiency caused by the fact that most grinding machines have a fixed structure and require the replacement of the corresponding grinding machine to grind bearings of different specifications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bearing ring outer diameter grinding platform, including a gantry frame, a water tank fixedly connected to the bottom of the gantry frame, a waterproof motor fixedly connected to the bottom of the water tank, a grinding machine fixedly connected to the output end of the waterproof motor, four inner support plates slidably connected to the top of the grinding machine, fixing strips fixedly connected to opposite sides of the four inner support plates, connecting rods rotatably connected to the upper and lower ends of the four fixing strips, a threaded rod rotatably connected to the top of the grinding machine, a threaded sleeve threadedly connected to the outside of the threaded rod, four connecting strips fixedly connected to the outer circumference of the threaded sleeve, and eight connecting rods rotatably connected to the upper and lower ends of the four connecting strips at their ends away from the inner support plates, and a spraying mechanism provided on one side of the water tank.

[0006] As a further description of the above technical solution:

[0007] The spraying mechanism includes a water pump, the input end of which is fixedly connected to one side of the water tank, the output end of which is fixedly connected to a water pipe, a heat dissipation fin is fixedly connected to the bottom of the gantry frame, a fan is fixedly connected to one side of the gantry frame, a connecting pipe is fixedly connected to the end of the water pipe away from the water pump, and an atomizing nozzle is fixedly connected to the bottom of the connecting pipe.

[0008] As a further description of the above technical solution:

[0009] The top of the grinding machine has four sliding grooves, and the bottom ends of the four inner support plates are slidably connected inside the sliding grooves.

[0010] As a further description of the above technical solution:

[0011] The top end of the threaded rod is fixedly connected to a throttle, and the outside of the throttle is covered with an anti-slip sleeve.

[0012] As a further description of the above technical solution:

[0013] A robotic arm is fixedly connected to the top of the inside of the gantry frame, and a grinding wheel is fixedly connected to the bottom of the robotic arm.

[0014] As a further description of the above technical solution:

[0015] The input end of the water pump passes through one side of the water tank, and a filter screen is provided at the input end of the water pump.

[0016] As a further description of the above technical solution:

[0017] The water pipe runs through the interior of the heat dissipation fins.

[0018] As a further description of the above technical solution:

[0019] The bottom end of the water pump is fixedly connected to the inner bottom end of the gantry frame, and the outside of the water pipe is fixedly connected to the inner top end of the gantry frame.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the threaded sleeve moves downward by rotating the throttle, and the inner support plate slides outward through the connecting rod until it is close to the inner ring of the bearing. The position of the grinding wheel is adjusted by the robotic arm, and the waterproof motor is started to begin the grinding operation. This achieves the effect that the grinding machine can be used to grind bearings of various specifications at the same time. Moreover, the inner support clamping has high stability and ensures that the bearing will not fall off due to high-speed rotation during the grinding operation, thereby improving production efficiency and ensuring production quality.

[0022] 2. In this utility model, water from the water tank is pumped into the water pipe by starting the water pump, flows through the heat dissipation fins, and is cooled again by the fan. The water flows through the connecting pipe into the atomizing nozzle and sprays onto the outside of the bearing. The water that drips off will fall back into the water tank for recycling. This achieves the effect of cooling the bearing and grinding wheel by spraying, ensuring that the grinding wheel will not be damaged due to overheating. Furthermore, the recycling of water saves water resources and reduces production costs. Attached Figure Description
