Description

Technical Field

[0001] This utility model relates to the field of bearing cover grinding, and in particular to a bearing cover end face grinding device. Background Technology

[0002] Bearing caps, as key components in mechanical equipment, play multiple important roles. They are not only protective shells for bearings, preventing dust, moisture and other contaminants from entering, thus maintaining the cleanliness and working performance of the bearings, but also serve to fix and support the bearings, ensuring their stable operation on the shaft. At the same time, bearing caps must withstand the axial force from the bearings to ensure the stability of the equipment structure.

[0003] Bearing caps are generally cast. After casting, the bearing caps are first cut and trimmed to the required dimensions. Then, the end faces of the bearing caps are ground to make them smooth and aesthetically pleasing, which also facilitates subsequent painting or electrostatic spraying. When grinding the bearing caps, a grinding head is usually used. The grinding head and the bearing cap are aligned, and the grinding head is pressed down to grind. This grinding method is relatively slow and has low grinding efficiency.

[0004] Therefore, it is necessary to propose a bearing cap end face grinding device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a bearing cap end face grinding device to solve the problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing cover end face grinding device, including a grinding box and a grinding disc movably disposed above the grinding box, wherein an annular grinding shell is provided at the upper end of the grinding box, and an elliptical plate is rotatably disposed on the inner side of the annular grinding shell;

[0007] Multiple gears are movably arranged inside the annular grinding shell, and multiple storage holes for storing bearing covers are opened through the upper end of the gears.

[0008] A toothed ring is fixedly provided on the outer side of the elliptical plate, and the toothed ring and the gear mesh with each other. A grinding motor is fixedly provided on the inner side of the grinding box, and the output shaft of the grinding motor is fixedly connected to the lower end of the elliptical plate.

[0009] Preferably, the inner wall of the annular grinding shell is provided with multiple guide grooves, a guide block is movably provided inside the guide groove, the lower end of the gear is rotatably connected to the guide block, one end of the guide block is fixedly provided with a spring, and the end of the spring is fixedly connected to the inner wall of the corresponding guide groove.

[0010] Preferably, the inner wall of the guide groove is provided with a water outlet hole, the inner side of the guide groove is provided with a plug for sealing the water outlet hole, the inner side of the grinding box is provided with a water tank, and the guide groove is connected to the water tank through the water outlet hole.

[0011] Preferably, the elliptical plate and the gear are at the same height.

[0012] Preferably, the lower side of the grinding disc and the inner wall of the annular grinding shell are both provided with polishing surfaces.

[0013] Preferably, the plurality of gears are arranged in a circular array, and the two ends of the bearing cover respectively contact the polishing and grinding surfaces of the grinding disc and the annular grinding shell.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting multiple gears and storage holes on the gears, multiple bearing covers can be ground simultaneously. The gear ring drives multiple gears to rotate, which can further improve the grinding efficiency when grinding multiple bearing covers at the same time. The ring grinding shell and grinding disc are used to grind the bearing covers on both sides.

[0016] 2. By setting the elliptical plate, when the gear is driven to rotate by the gear ring, the gear can reciprocate while rotating with the help of the guide groove and guide block, thereby increasing the range of motion of the gear and maximizing the use of the polishing surface on the ring grinding shell and the grinding disc, thus preventing the problem of rapid wear of the polishing surface caused by a single position.

[0023] This utility model provides, for example Figure 1 - Figure 5 The bearing cover end face grinding device shown includes a grinding box 1 and a grinding disc 3 movably disposed above the grinding box 1. The grinding disc 3 is controlled by a grinding device and a servo system. The grinding disc 3 can move up and down and also move in the parallel direction to facilitate the loading and unloading of the bearing cover. The grinding device and the servo system are existing technologies and will not be described in detail here. A water tank is provided inside the grinding box 1. The water tank is not directly shown in the figure. The water tank is equipped with a filtration system and a water pump for water circulation. The water tank, the water pump and the filtration system are existing technologies and will not be described in detail here.

[0024] The grinding box 1 has an annular grinding shell 4 at its upper end. Polishing surfaces are provided on the lower side of the grinding disc 3 and the inner wall of the annular grinding shell 4 to facilitate grinding the two end faces of the bearing cover. Polishing surfaces are a common existing grinding method and are not described in detail here. The annular grinding shell 4 is used to store water; adding water ensures the grinding effect. An elliptical plate 5 is rotatably mounted inside the annular grinding shell 4, and multiple gears 7 are movably mounted inside the annular grinding shell 4. Multiple storage holes 8 for storing the bearing cover are opened through the upper end of each gear 7. The bearing cover is placed inside the storage holes 8, and the lower end of the bearing cover is lifted by gravity. The inner wall of the annular grinding shell 4 is in contact with the elliptical plate 5. A toothed ring 6 is fixedly installed on the outer side of the elliptical plate 5. The toothed ring 6 and the gear 7 mesh with each other. A grinding motor 2 is fixedly installed on the inner side of the grinding box 1. The grinding motor 2 is a servo geared motor with the characteristics of high torque and low speed. It is existing technology and will not be described in detail here. The output shaft of the grinding motor 2 is fixedly connected to the lower end of the elliptical plate 5. When the operator turns on the grinding motor 2, the grinding motor 2 drives the elliptical plate 5 to rotate. The elliptical plate 5 drives the toothed ring 6 to rotate. The toothed ring 6 drives multiple gears 7 to move simultaneously through tooth meshing. The multiple gears 7 drive multiple bearing covers to move.

[0025] Multiple guide grooves 9 are provided on the inner wall of the annular grinding shell 4. Guide blocks 10 are movably provided on the inner side of the guide grooves 9. The lower end of the gear 7 is rotatably connected to the guide block 10. A spring 11 is fixedly provided at one end of the guide block 10. The end of the spring 11 is fixedly connected to the inner wall of the corresponding guide groove 9. The spring 11 constantly presses the guide block 10, causing the gear 7 driven by the guide block 10 to move. The gear 7 is constantly in contact with the toothed ring 6. In this way, when the elliptical plate 5 rotates, it can drive multiple gears 7 to rotate and also drive multiple gears 7 to reciprocate, thereby increasing the moving distance of the bearing cover.

[0026] The inner wall of the guide groove 9 is provided with a water outlet hole 12. The inner side of the guide groove 9 is provided with a plug for sealing the water outlet hole 12. The guide groove 9 is connected to the water tank through the water outlet hole 12. Excess water enters the water tank from the water outlet hole 12 to facilitate water circulation. The elliptical plate 5 and the gear 7 are at the same height, which makes it easy for the grinding disc 3 to contact multiple bearing covers at the same time. The multiple gears 7 are arranged in a ring array. The two ends of the bearing cover contact the polishing and grinding surfaces of the grinding disc 3 and the ring grinding shell 4, respectively.

[0027] By setting multiple gears 7 and storage holes 8 on the gears 7, multiple bearing covers can be ground simultaneously. The gear ring 6 drives the multiple gears 7 to rotate, which can further improve the grinding efficiency when grinding multiple bearing covers at the same time. The bearing cover can be ground on both sides by setting an annular grinding shell 4 and a grinding disc 3.

[0028] By setting the elliptical plate 5, when the gear ring 6 drives the gear 7 to rotate, the guide groove 9 and guide block 10 assist the gear 7 to reciprocate while rotating, thereby increasing the range of motion of the gear 7 and maximizing the use of the polishing and grinding surfaces on the annular grinding shell 4 and the grinding disc 3, thus preventing the problem of rapid wear of the polishing and grinding surfaces caused by a single position.
