Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a safe automatic bearing polishing device. Background Art

[0002] Bearings are a commonly used mechanical component. Bearings can make the mechanical structure rotate in a straight line to achieve the purpose of use. In order to reduce rotational resistance, the polishing degree of the bearing is a very important factor. Therefore, in production, there are very high requirements for the polishing of the outer surface of the bearing.

[0003] At present, with the increasing requirements for safe production, in the field of bearing production, the safety requirements for bearing processing equipment are also getting higher and higher, especially polishing devices. When polishing bearings, more debris will be generated, and the debris will fly everywhere. Since the cut debris has a high temperature, it will splash onto human skin and cause burns to operators (or other safety issues). Therefore, the current bearing processing equipment is equipped with corresponding safety protection mechanisms to reduce dangerous factors and improve the effect of safe production.

[0004] However, with the development of the processing and manufacturing industry, the demand for bearings is increasing. While improving production safety, it is also necessary to improve the processing efficiency of bearings, reduce labor, and increase the degree of automation in bearing processing. While reducing labor, it can also reduce the phenomenon of high-temperature debris scalding operators, and further improve production safety effects. Therefore, automated bearing processing is also a necessary improvement measure for the development of the bearing production industry.

[0005] At present, most of the traditional bearing processing adopts grinding to polish it. During polishing, it is mostly necessary to manually adjust the polishing surface of the bearing to make it contact with the polishing equipment to achieve the purpose of polishing. Although the polishing effect can meet the production requirements of the bearing, the manual replacement of the polishing end face of the bearing is obviously not in line with the current bearing processing efficiency. Although the drum polishing method can polish different outer surfaces of the bearing at the same time, the polishing time is too long, which affects the production efficiency. Therefore, in view of the low automation defect of bearing surface polishing, a safe bearing automatic polishing device is proposed. Utility Model Content

[0058] A lifting component four is provided at the bottom of the limiting frame, and the lifting component four controls the sorting bucket to rise and fall in a vertical direction.

[0059] The working principle and beneficial effects of the utility model are:

[0060] In the utility model

[0061] 1. Two rollers drive the bearing to rotate, and the end face polishing feed assembly and the end face polishing close assembly move the end face polishing wheel to the end face of the bearing for polishing. After the bearing is polished, the end face polishing wheel is removed. At the same time, the limit assembly keeps the bearing in a fixed position so that the bearing does not move during polishing. The lifting assembly 4 is detachably connected to the bottom of the limit frame, and the bearing is released after the bearing is polished;

[0062] The outer ring polishing assembly and the inner ring polishing assembly respectively move the outer ring polishing wheel and the inner ring polishing wheel to the outer ring and the inner ring of the bearing for polishing, thereby completing the polishing of all the end faces of the bearing. After the bearing is polished, the outer ring polishing wheel and the inner ring polishing wheel are moved;

[0063] When the bearing is polished, the guide mechanism presses the bearing to prevent it from jumping. Because there are guide grooves on the guide wheel, when the guide wheel presses the bearing, the bearing receives axial force and moves between the rollers along the axial direction of the rollers. It is positioned by the second limit plate. After the bearing moves to the polishing position of the inner and outer rings, it will no longer move.

[0064] 2. Feeding is performed through the intermittent feeding mechanism. Since the inclination angle of the sorting bucket is greater than that of the first and second feeding buckets, when the sorting bucket is at the lowest point, the right end of the sorting bucket is lower than the left end of the second feeding bucket, which blocks the bearing in the sorting bucket and prevents the material from entering the second feeding bucket;

[0065] When the lifting assembly 1 lifts the sorting bucket, the right end of the sorting bucket is higher than the left end of the feeding bucket 2, and the bearing in the sorting bucket rolls into the feeding bucket 2 for further processing. At the same time, the left end of the sorting bucket is higher than the right end of the feeding bucket 1, blocking the bearing in the feeding bucket 1 and preventing it from entering the sorting bucket;

[0066] When the lifting component 1 lowers the sorting bucket, the left end of the sorting bucket is lower than the right end of the feeding hopper 1, and the bearing in the feeding hopper 1 enters the sorting bucket. At the same time, the right end of the sorting bucket is lower than the left end of the feeding hopper 2, which blocks the bearing in the sorting bucket and prevents it from entering the feeding hopper 2. At the same time, the length of the sorting bucket is set to be the same as the diameter of the bearing to avoid multiple bearings entering the sorting bucket at the same time, thereby completing the intermittent feeding of the bearings;

[0067] 3. Discharge is carried out through the discharging mechanism. After the bearing is polished, the lifting component three lifts the discharging frame so that the polished bearing can roll into the discharging hopper one, and then roll into the discharging hopper two to complete the automatic discharging.

[0068] To sum up, in the utility model, the intermittent feeding mechanism and the discharging mechanism are provided to complete the automatic feeding and discharging of the bearing, thereby increasing the degree of automation, and the safety cover is provided to avoid direct contact between the staff and the polishing device, thereby protecting the safety of the staff, and the automatic polishing of the bearing is completed by providing a guiding mechanism, an end face polishing mechanism, and an inner and outer ring polishing mechanism, thereby realizing the automation of polishing, and the polishing process does not require human intervention, and the bearing polishing is completed by adding a limit plate and a limit assembly to assist, thereby improving stability.

[0113] In the present embodiment, a safe bearing automatic polishing device is provided. When the staff puts the unpolished bearing into the feeding hopper 1 32, the unpolished bearings enter the safety cover 1 one by one and roll into the sorting bucket 33. Since the inclination angle of the sorting bucket 33 is greater than that of the feeding hopper 1 32 and the feeding hopper 2 35, when the sorting bucket 33 is at the lowest point, the bearing in the feeding hopper 1 32 enters the sorting bucket 33. At the same time, the right end of the sorting bucket 33 is lower than the left end of the feeding hopper 2 35, the bearing in the sorting bucket 33 is stuck and prevented from entering the feeding hopper 2 35. At the same time, the length of the bottom surface of the sorting bucket 33 is set to be the same as the diameter of the bearing, so that only one bearing can roll into the sorting bucket, preventing multiple bearings from rolling into the sorting bucket at the same time.

[0114] When the lifting component 1 34 lifts the sorting bucket 33, the right end of the sorting bucket 33 is higher than the left end of the feeding hopper 2 35, and the bearing in the sorting bucket 33 rolls into the feeding hopper 2 35 for further processing. At the same time, the left end of the sorting bucket 33 is higher than the right end of the feeding hopper 1 32, which blocks the bearing in the feeding hopper 1 32 and prevents it from entering the sorting bucket 33. When the lifting component 1 34 lowers the sorting bucket 33, a bearing rolls into the unloading hopper, thereby completing the intermittent feeding of the bearings.

[0115] When the bearing 1 extension hopper 2 35 rolls in between the two rollers 2, due to the limit plate 2 4501, the bearing 1 will not roll out from between the two rollers 2 due to inertia, and at the same time, the lifting component 4503 lifts the limit frame 4502 to contact the bearing to reach the limit, and the end face polishing feed component 41 and the end face polishing approaching component 42 push the end face polishing wheel 44 to contact the end face of the bearing 1, and at the same time, the lifting component 2 51 lowers the guide wheel 54 to press the bearing 1 to start polishing the end face of the bearing 1.

[0116] When the end face of bearing one is polished, the lifting assembly 4503 lowers the limit frame 4502 to leave bearing one, and at the same time, the end face polishing feeding assembly 41 and the end face polishing approaching assembly 42 push the end face polishing wheel 44 away from the end face of bearing one, and the guide wheel 54 still presses bearing one. Since there are guide grooves on the guide wheel 54, it pushes bearing one to move along the axis of the two rollers 2. After bearing one moves a certain distance between the two rollers 2, the lifting assembly 2 51 lifts the guide wheel 54 to leave bearing one, and then the intermittent feeding mechanism 3 performs the second feeding, and bearing two enters between the two rollers 2.

[0117] Then the lifting component 2 51 lowers the guide wheel 54 and presses the bearing 1 and the bearing 2 at the same time. The bearing 1 continues to move along the axis of the two rollers 2, and the bearing 2 performs end face polishing. After a period of time, when the bearing 1 moves to the limit plate 1 67, the bearing 1 stops moving along the axis of the two rollers 2 due to the limit plate 1 67. At the same time, the outer ring polishing component 64 and the inner ring polishing component 61 move the outer ring polishing wheel 66 and the inner ring polishing wheel 63 to the outer ring and inner ring of the bearing 1 respectively, and polish the outer ring and inner ring of the bearing 1. After a period of time, when the end face polishing mechanism 4 completes the polishing of the end face of the bearing 2, the lifting component 4503 lowers the limit frame 4502 to leave the bearing 2. At the same time, the end face polishing feed component 41 and the end face polishing approaching component 42 push the end face polishing wheel 44 away from the end face of the bearing 2. The guide wheel 54 still presses the bearing 1 and the bearing 2. The bearing 2 moves along the axis of the two rollers 2. At this time, the bearing 1 is still polishing the inner ring and the outer ring.

[0118] After a period of time, bearing two moves a distance between the two rollers 2, and bearing one completes the polishing of the inner and outer rings. The outer ring polishing assembly 64 and the inner ring polishing assembly 61 move the outer ring polishing wheel 66 and the inner ring polishing wheel 63 away from bearing one. At the same time, the lifting assembly two 51 lifts the guide wheel 54 away from bearing one and bearing two, and the lifting assembly three 72 lifts the discharge rack 71 to allow bearing one to enter the discharge hopper one 74. Then the lifting assembly three 72 lowers the discharge rack 71, and at the same time the intermittent feeding mechanism 3 feeds for the third time, and bearing three enters between the two rollers 2. This cycle is repeated to automatically polish the bearing.

[0119] The bearing 1 rolls into the discharge hopper 1 74 and then leaves the safety cover 1 and rolls into the discharge hopper 2 75 to complete the polishing.
