Description

Technical Field

[0001] The present invention relates to the field of thin-wall bearing production equipment, and in particular to thin-wall bearing production equipment and a production process. Background Art

[0002] At present, the grinding machine for bearing rings is a kind of grinding machine usually used for precision grinding of bearing rings to ensure that their dimensional accuracy and surface quality meet specific requirements. The thin-walled bearing production equipment is a kind of equipment used in automated production lines to transport bearing rings to the grinding machine for processing.

[0003] Existing thin-walled bearing production equipment requires a combination of multiple devices, including conveyor belts, manipulators, etc., and its operation is generally equipped with two sets of coolant pipelines to cool the bearing rings during or after grinding, so as to facilitate the rapid unloading of the cooled bearing rings for the next processing, otherwise it will take a long time to cool. However, due to the angle limitation of the spray head of the coolant pipeline itself, its spraying range is limited, so that the bearing rings on the transfer plate cannot be fully flushed and cooled. Summary of the invention

[0004] In view of the above problems, the present invention proposes a thin-walled bearing production equipment, which solves the defect that the existing thin-walled bearing production equipment requires a combination of multiple devices, and due to the angle limitation of the spray head of the coolant pipeline itself, its spraying range is limited, so that the bearing ring on the transfer plate cannot be fully flushed and cooled.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A thin-walled bearing production equipment comprises: a frame, a mounting plate is provided on the frame, a first guide rail, a second guide rail and a swing arm are provided on the mounting plate, one side of the mounting plate is used to place a grinding assembly, a loading plate for loading a bearing ring is provided on the swing arm, a first cylinder is provided at the rear end of the frame to drive the swing arm to move forward and backward, a swing mechanism is fixed on the first cylinder, the swing mechanism drives the swing arm to swing, and transfers the bearing ring from the receiving assembly to the grinding assembly; a material guide arc plate is provided on the second guide rail, a first coolant spray pipe and a second coolant spray pipe are provided on the upper right side of the material guide arc plate, an elastic sheet is provided in the middle of the material guide arc plate, the first coolant spray pipe is directly facing the elastic sheet of the material guide arc plate, a fixed block is provided on the elastic sheet, an elastic telescopic rod is connected to the bottom of the fixed block, a fixed plate is provided at the bottom of the elastic telescopic rod, and the coolant sprayed from the first coolant spray pipe impacts the elastic sheet so that the elastic sheet is concave downward and the liquid splashes upward. In the present invention, the coolant sprayed from the first coolant spray pipe impacts the elastic sheet, causing the elastic sheet to sag downward and causing the liquid to splash upward. When the loading plate drives the bearing ring to swing back and forth, and the bearing ring of the loading plate has not completely moved to the guide arc plate, the splashed liquid can fully flush the lower area of ​​the bearing ring, thereby making the cooling more sufficient.

[0007] Optionally, the swing mechanism includes a second cylinder and a connecting rod hinged to the second cylinder, a rotating shaft is provided on the connecting rod, and one end of the swing arm away from the loading plate is fixedly connected to the rotating shaft.

[0008] Optionally, a receiving assembly for receiving a bearing ring is provided below the first guide track.

[0009] Optionally, the second coolant spray pipe is directly facing the grinding assembly.

[0010] Optionally, the outer edge of the loading tray is provided with a first arc-shaped protective sheet at the top and a second arc-shaped protective sheet at the bottom, and the first protective sheet and the second protective sheet of the loading tray are used to move toward each other under the action of the internal driving structure.

[0011] Optionally, a magnetic piece is mounted on the second protective sheet; the fixing block is made of magnetic material, and the magnetic poles of the magnetic piece and the opposite surface of the fixing block are opposite, so that the two repel each other.

[0012] Optionally, a plurality of guide holes are provided in the middle of the first protective sheet, and gaskets are provided at both ends of the lower portion of the first protective sheet.

[0013] Optionally, a pair of elastic guide plates are provided in the guide hole, and the guide plates are arched toward the central axis of the guide hole and extend from the top of the guide hole obliquely to the central axis of the guide hole.

[0014] Optionally, a pair of guide plates form a guide channel; the central axis of the guide channel faces the center of the loading tray.

At this time, the first cylinder applies thrust to the frame to drive the swing arm to move backward, and at the same time the loading plate clamps the bearing ring, and then moves the bearing ring to one side of the grinding wheel of the grinder and uses the grinding wheel of the grinder to grind the outer ring wall of the thin-walled bearing, and when the bearing ring of the loading plate has not completely moved to the guide arc plate, the coolant sprayed from the first coolant spray pipe impacts the elastic sheet, causing the elastic sheet to sag downward and the liquid to splash upward.

[0016] Beneficial Effects

[0017] 1. In the present invention, the coolant sprayed from the first coolant spray pipe impacts the elastic sheet, causing the elastic sheet to sag downward and the liquid to splash upward, so that when the loading plate drives the bearing ring to swing back and forth, and when the bearing ring of the loading plate has not completely moved to the guide arc plate, the splashed liquid can fully flush the lower area of ​​the bearing ring, so that the cooling is more sufficient.

[0019] 3. In the present invention, when the flow rate of the sprayed liquid is high, the elastic guide plate will open, increasing the flow rate. The guide plate is arched toward the central axis of the guide hole and extends obliquely downward from the top of the guide hole. The guide channel is bucket-shaped. According to the Bernoulli effect, the liquid flow rate is guaranteed, so that the liquid quickly flushes the bearing ring and disperses, increasing the contact area.

[0030] Example 1

[0031] The technical solution adopted by the present invention is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a thin-walled bearing production equipment comprises: a frame 1, a mounting plate 2 is provided on the frame, a first guide rail 3, a second guide rail 4 and a swing arm 5 are provided on the mounting plate, one side of the mounting plate is used to place a grinding assembly, a loading plate 7 for loading bearing rings is provided on the swing arm, a first cylinder 8 for driving the swing arm to move forward and backward is provided at the rear end of the frame, a swing mechanism 9 is fixed on the first cylinder, the swing mechanism drives the swing arm to swing, and transfers the bearing ring from the receiving assembly to the grinding assembly; a guide arc plate 10 is provided on the second guide rail, a first coolant spraying pipe 11 and a second coolant spraying pipe 12 are provided on the upper right side of the guide arc plate, an elastic sheet 13 is provided in the middle of the guide arc plate, the first coolant spraying pipe is directly opposite to the elastic sheet of the guide arc plate, a fixing block 14 is provided on the elastic sheet, an elastic telescopic rod 15 is connected to the bottom of the fixing block, a fixing plate 16 is provided at the bottom of the elastic telescopic rod, and the coolant sprayed from the first coolant spraying pipe impacts the elastic sheet so that the elastic sheet is concave downward and the liquid splashes upward. The elastic telescopic rod of this embodiment is used to provide elasticity for restoring the guide arc plate.

[0033] In this embodiment, the second coolant spraying pipe faces the grinding assembly.

[0034] In this embodiment, one implementation of the swing mechanism is as follows: the swing mechanism includes a second cylinder 6 and a connecting rod 17 hinged on the second cylinder, the connecting rod is provided with a rotating shaft 18, and the end of the swing arm away from the loading plate is fixedly connected to the rotating shaft. A receiving assembly 19 for receiving the bearing ring is provided below the first guide track. The first rotating shaft drives the swing arm to swing, and transfers the bearing ring from the receiving assembly to the grinding assembly.

[0035] When this embodiment is implemented, the bearing ring rolls from the first guide track to the receiving mechanism, and the second cylinder drives the connecting rod to move, so that it drives the rotating shaft to rotate, and the swing arm and the loading plate on the swing arm rotate to the front of the bearing ring. At this time, the first cylinder applies thrust to the frame, driving the swing arm to move backward. At the same time, the loading plate clamps the bearing ring, and when the bearing ring of the loading plate has not completely moved to the guide arc plate, the coolant sprayed from the first coolant spray pipe impacts the elastic sheet, causing the elastic sheet to sag downward and the liquid to splash upward.

[0036] Example 2

[0037] like Figure 5As shown, the difference between this embodiment 2 and embodiment 1 is that the outer edge of the loading tray is provided with a first arc-shaped protective sheet 20 located at the top and a second arc-shaped protective sheet 21 located at the bottom. The first protective sheet and the second protective sheet of the loading tray are used to move toward each other under the action of the internal driving structure. The driving structure inside the loading tray can be a set of motors whose output shafts rotate to drive gears to rotate, and a pair of racks are meshed on both sides of the gears, and the pair of racks are respectively connected to the first protective sheet and the second protective sheet, and the rotation of the gears can realize the movement of the first protective sheet and the second protective sheet toward or away from each other.

[0038] The second protection sheet is provided with a magnetic member 22. The fixing block is made of magnetic material, and the magnetic poles of the opposite surfaces of the magnetic member and the fixing block are opposite, so that the two repel each other.

[0039] When this embodiment is implemented, when the bearing ring of the loading plate is completely moved to the guide arc plate, the linear distance between the magnetic part and the fixed block is the smallest. Since the magnetic poles of the opposite surfaces of the magnetic part and the fixed block are opposite, the two repel each other. Finally, due to the repulsive force of the fixed block on the magnetic part, the guide arc plate is concave and bent inward. Part of the coolant sprayed from the first coolant spray pipe is reflected and converged to the bottom surface of the bearing ring through the groove formed by the inward concave bend at this time, and the bearing ring can still be cooled at this time. It should be noted that when the bearing ring of the loading plate has not completely moved to the guide arc plate, the linear distance between the magnetic part and the fixed block is large, and the repulsive force of the fixed block on the magnetic part is very small, and the guide arc plate will not be concave and bent inward.

[0040] Example 3

[0041] like Figure 6 As shown, the difference between this embodiment 3 and embodiment 2 is that a plurality of guide holes 23 are opened in the middle of the first protective sheet, and gaskets 25 are respectively provided at both ends of the lower part of the first protective sheet. A pair of elastic guide plates 24 are provided in the guide hole, and the guide plates are arched toward the central axis of the guide hole and extend obliquely downward from the top of the guide hole. A pair of guide plates form a guide channel. The central axis of the guide channel is directly opposite to the center of the loading plate.

[0042] When this embodiment is implemented, when the coolant sprayed from the first coolant spray pipe flushes the loading plate, part of the liquid passes through the guide channel of the guide hole to cool the bearing ring on the loading plate, thereby enhancing the cooling effect on the bearing ring when the loading plate drives the bearing ring to swing back and forth; and when the flow rate of the sprayed liquid is large, the elastic guide plate will be opened, thereby increasing the flow rate, and the guide plate will be arched toward the central axis of the guide hole, and extend obliquely from the top of the guide hole to the central axis of the guide hole, and its guide channel is bucket-shaped (with a large opening at the upper end and an open pin at the lower end), which ensures the liquid flow rate according to the Bernoulli effect, so that the liquid quickly flushes the bearing ring and disperses, thereby increasing the contact area.
