Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing equipment, in particular to a bearing outer ring grinding device. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Before assembly, the inner and outer rings of the bearings need to be ground so that the roughness of the inner and outer circumferential surfaces meets the assembly requirements. The existing outer ring grinding mostly uses the lathe chuck for positioning and then grinding. After the processing is completed, the other outer ring of the bearing to be ground is clamped. In this process, waiting time is wasted, which is not conducive to batch processing, labor intensity is high, and production costs are high. The "a bearing outer ring grinding device" disclosed in the application number "CN201820702927.3" solves the problem that the existing outer ring grinding mostly uses the chuck of the lathe for positioning and then grinding through a specific technical structure setting. After the processing is completed, another bearing outer ring to be ground is clamped. In this process, waiting time is wasted, which is not conducive to batch processing, labor intensity is high, and production cost is high. However, the device still has some problems, such as: it uses a rotatable rotating disk to change the position of the four clamping cylinders, so that the four bearings clamped by the clamping cylinders can be rotated to the grinding disk for grinding. However, the debris generated during the grinding process will splash everywhere, which not only requires the staff to clean it up, but also may cause injuries if it flies to the staff, and the water used for cooling is not effectively recovered after being sprayed out, and flows on the equipment or the ground, causing pollution and waste. Utility Model Content

[0003] The purpose of the utility model is to provide a bearing outer ring grinding device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bearing outer ring grinding device, comprising a box body, a grinder body, a clamping device body and a chuck, the grinder body is fixed to one side of the inner top end of the box body, a first outer shell is provided inside the grinder body, a hydraulic cylinder is fixed to the other side of the inner top end of the box body, the output end of the hydraulic cylinder is connected to the clamping device body, a second outer shell is provided inside the clamping device body, a gathering bucket is fixed in the middle of the inner part of the box body, the outer bottom end of the gathering bucket is connected to a water tank through a first pipe, and the water tank is fixed to the inner bottom end of the box body.

[0005] When using a bearing outer ring grinding device in the present technical solution, the staff must first connect the power supply to the utility model, control the operation of the utility model through the control panel, and the staff rotates to open the box door. After the box door is rotated and opened, the staff places the bearing to be ground inside the box and puts it on the surface of the two support plates. After putting it on, the staff starts the two-way guide rail, and the two-way guide rail moves the two support plates in opposite directions. The two support plates will move inside the bearing and support and fix it from the inside of the bearing. After the bearing is supported and fixed, the staff starts the second motor and the first motor. The second motor rotates the chuck connected to the output end. After the chuck rotates, the bearing supported and fixed by the support plate will rotate accordingly, and the first motor will rotate the grinding wheel connected to the output end. After the grinding wheel rotates, the staff starts the hydraulic cylinder, and the hydraulic cylinder lifts the clamping device body connected to the output end. The clamping device body rises Then the bearing fixed by the support plate will rise up, and the raised bearing will stick to the surface of the grinding wheel. Because the second motor and the first motor have opposite directions, the outer ring surface of the bearing rotating in the opposite direction can be ground by the rotating grinding wheel. When the bearing is ground, the staff also needs to start the pump body, and the pump body draws water in the water tank into it through the second pipe, and then transmits it to the inside of the nozzle through the third pipe. The nozzle sprays water to the contact position between the bearing and the grinding wheel for cooling. The cooled water containing debris generated by the grinding process will flow into the collection bucket, and will be transmitted back to the inside of the water tank through the collection bucket and the first pipe for recycling. The debris contained in the water will be filtered by the filter. After a certain period of time, the staff needs to open the box door to take out the filter in the collection bucket and clean it for subsequent use.

[0006] Preferably, a pump body is fixed to the inner side of the box body, the input end of the pump body is connected to the inside of the water tank through the second pipe, and the output end of the pump body is connected to one end of the nozzle through the third pipe. Through the cooperation of the second pipe, the pump body and the third pipe, the water in the water tank can be pumped to the inside of the nozzle, achieving the effect of active pumping.

[0007] Preferably, a first motor is fixed inside the first housing, and a grinding wheel is connected to the output end of the first motor. Through the cooperation of the first motor and the grinding wheel, the outer ring surface of the bearing supported and fixed by the support plate can be ground, achieving the effect of rotational grinding.

[0008] Preferably, a second motor is fixed inside the second housing, and a chuck is connected to the output end of the second motor. Through the cooperation between the second motor and the chuck, the bearing fixed by the support plate can rotate, achieving the effect of rotating in the opposite direction to the grinding wheel and then grinding.

[0009] Preferably, a two-way guide rail is fixed inside the chuck, and support plates are slidably mounted on both ends of the surface of the two-way guide rail. Through the cooperation of the two-way guide rail and the support plate, bearings of different sizes can be supported and fixed from inside, achieving the effect of supporting and fixing the bearings inside.

[0010] Preferably, a box door is rotatably mounted on the outer front surface of the box, and a visual window is embedded in the box door. The box door is installed so that the staff can rotate it to open and place the bearing inside the box for processing, providing a passage position for taking and placing, and the visual window is installed so that the staff can also see the grinding process of the internal bearing without opening the box door.

[0011] Preferably, a filter screen is placed at the inner bottom of the gathering bucket. By providing the filter screen, the debris contained in the water can be filtered out and left behind, achieving the effect of filtering out the debris and making it easier to clean up.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

After the box door 13 is turned and opened, the staff places the bearing to be ground inside the box body 2 and puts it on the surface of the two support plates 54. After putting it, the staff starts the two-way guide rail 55. The two-way guide rail 55 moves the two support plates 54 in reverse, and the two support plates 54 will move inside the bearing and support and fix it from the inside of the bearing. After the bearing is supported and fixed, the staff starts the second motor 52 and the first motor 32. The second motor 52 rotates the chuck 53 connected to the output end.
