Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing roller end face grinding technology, specifically a material discharge device for bearing roller end face grinding. Background Technology
[0002] Bearing roller end face grinding is a precision machining process used to improve the flatness and surface finish of bearing roller end faces, thereby improving bearing performance and service life. This machining process is mainly used in the manufacture of high-quality rolling bearings, especially in applications requiring high precision and long service life, such as automobiles, aircraft, and industrial machinery.
[0003] Existing bearing roller end face grinding and unloading devices use a receiving box to collect the bearing rollers after grinding for convenience. However, after grinding, the bearing rollers are directly pushed into the receiving box by the unloading mechanism, which cannot buffer the bearing rollers. As a result, the bearing rollers are prone to hitting the receiving box during the falling process, which can cause damage to the bearing rollers. Utility Model Content
[0004] The purpose of this invention is to provide a discharge device for grinding the end face of bearing rollers, so as to solve the problem mentioned in the background art that the bearing rollers currently in use do not have a buffering effect during discharge, which makes the bearing rollers easy to be damaged by impact.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a discharge device for grinding the end face of bearing rollers, comprising: a grinding table and a discharge port, wherein a drive motor is installed inside the grinding table through a groove, the output end of the drive motor is connected to a lead screw through a coupling, a threaded sleeve is sleeved on the outside of the lead screw, a storage plate is installed on the top of the threaded sleeve, a fixing block is in the groove of the grinding table, and the discharge port is opened at the bottom of the grinding table;
[0006] The inner wall of the discharge port is connected to a buffer plate via a rotating shaft. The bottom of the buffer plate is connected to a lower connecting rod via a rotating shaft. The end of the lower connecting rod away from the buffer plate is connected to a lower sliding block via a rotating shaft. The bottom of the lower sliding block is connected to a lower telescopic block. A first spring is connected between the lower telescopic block and the groove of the grinding table. The side of the buffer plate is connected to an upper connecting rod via a rotating shaft. The end of the upper connecting rod away from the buffer plate is connected to an upper sliding block via a rotating shaft. The top of the upper sliding block is connected to an upper telescopic block. A second spring is connected between the upper telescopic block and the groove of the grinding table.
[0007] Preferably, both the lower slider and the upper slider are slidably connected in the groove of the grinding table via a sliding groove.
[0008] Preferably, two sets of buffer plates are symmetrically installed about the center line of the discharge port, and the buffer plates form a rotating structure with the inner wall of the discharge port through a rotating shaft.
[0009] Preferably, a guide rail is installed at the bottom of the grinding table, and a sliding block is slidably connected inside the guide rail.
[0010] Preferably, a receiving box is connected between the two sets of sliding blocks, and a rubber ball is installed inside the sliding block through a groove.
[0011] Preferably, one side of the rubber ball is connected to a wedge-shaped block that penetrates the sliding block, and one side of the wedge-shaped block is provided with a top rod that penetrates the guide rail.
[0012] Preferably, a telescopic rod is provided on one side of the receiving box, and a return spring is installed inside the telescopic rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the bearing roller end face grinding discharge device is in use, the bearing roller that needs to be discharged first falls into the discharge port and impacts the buffer plate in the discharge port. Since the buffer plate is connected to the inside of the discharge port through a rotating shaft, the buffer plate will rotate when impacted. This allows the first spring and the second spring to be compressed or stretched through the upper and lower connecting rods. The first spring and the second spring can buffer the bearing roller, thereby preventing the bearing roller from falling too fast and causing damage due to impact. This is the characteristic of the bearing roller end face grinding discharge device.
[0014] 1. The discharge device for grinding the end face of bearing rollers has the following characteristics: When the bearing rollers fall into the receiving box through the discharge port, they will first hit the buffer plate. At this time, the buffer plate is compressed by the cooperation of the upper and lower connecting rods, and the second spring is stretched. The first spring and the second spring can buffer the buffer plate, so that the bearing rollers will not be damaged due to violent impact with the receiving box when falling due to excessive speed.
[0015] 2. When the bearing roller end face grinding device needs to collect the bearing rollers in the receiving box, the push rod is pressed into the guide rail, so that the wedge block is compressed and retracted into the groove of the sliding block. At this time, the receiving box will move to one side along the guide rail under the reset action of the telescopic rod and the return spring, thus facilitating the collection of the bearing rollers in the receiving box.

They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] Please see Figure 1 This utility model provides a technical solution: a discharge device for grinding the end face of bearing rollers, comprising: a grinding table 1 and a discharge port 7. A drive motor 2 is installed inside the grinding table 1 through a groove. The output end of the drive motor 2 is connected to a lead screw 3 through a coupling. A screw sleeve 4 is sleeved on the outside of the lead screw 3. A storage plate 5 is installed on the top of the screw sleeve 4. A fixing block 6 is in the groove of the grinding table 1. The discharge port 7 is opened at the bottom of the grinding table 1.
[0025] A buffer plate 8 is connected to the inner wall of the discharge port 7 via a rotating shaft. A lower connecting rod 9 is connected to the bottom of the buffer plate 8 via a rotating shaft. A lower slider 10 is connected to the end of the lower connecting rod 9 away from the buffer plate 8 via a rotating shaft. A lower telescopic block 11 is connected to the bottom of the lower slider 10. A first spring 12 is connected between the lower telescopic block 11 and the groove of the grinding table 1. An upper connecting rod 13 is connected to the side of the buffer plate 8 via a rotating shaft. An upper slider 14 is connected to the end of the upper connecting rod 13 away from the buffer plate 8 via a rotating shaft. An upper telescopic block 15 is connected to the top of the upper slider 14. A second spring 16 is connected between the upper telescopic block 15 and the groove of the grinding table 1. Both the lower slider 10 and the upper slider 14 are slidably connected in the groove of the grinding table 1 through a sliding groove. Two sets of buffer plates 8 are symmetrically installed about the center line of the discharge port 7. The buffer plates 8 form a rotating structure with the inner wall of the discharge port 7 via a rotating shaft. Both the lower telescopic block 11 and the upper telescopic block 15 form a telescopic structure with the groove of the grinding table 1.
[0026] In specific implementation, the bearing roller end face grinding discharge device discharges the bearing rollers located on the storage tray 5 through the screw sleeve 4 and the lead screw 3. Since the position of the fixed block 6 remains unchanged, when the bearing rollers are discharged forward, they will be pushed down by the fixed block 6 and fall into the receiving box 19 at the bottom through the discharge port 7.
[0027] When the bearing rollers pass through the discharge port 7, the buffer plate 8 is tilted due to the supporting and pulling forces of the upper connecting rod 13 and the lower connecting rod 9. When the buffer plate 8 is subjected to the impact force of the falling bearing rollers, it will rotate downward through the rotating shaft.
[0028] When the buffer plate 8 rotates downward, it will push the lower connecting rod 9 to rotate downward through the rotating shaft. The other end of the lower connecting rod 9 is connected to one side of the lower slider 10 through the rotating shaft. The lower slider 10 can only slide along the groove of the grinding table 1. Therefore, when the lower connecting rod 9 rotates, it will push the lower slider 10 to slide downward. When the lower slider 10 slides downward, it will squeeze the lower telescopic block 11 at the bottom, so that the lower telescopic block 11 squeezes the first spring 12 in the groove of the grinding table 1.
[0029] At the same time, the buffer plate 8 rotates downward, causing one end of the upper connecting rod 13 to move downward. The other end of the upper connecting rod 13 is connected to one side of the upper slider 14 through a rotating shaft. The upper slider 14 can only slide in the groove of the grinding table 1. Therefore, when the upper connecting rod 13 moves downward, it will also drive the upper slider 14 to move downward, causing the upper telescopic block 15 at the top of the upper slider 14 to move downward. At this time, the upper telescopic block 15 will cause the second spring 16 in the groove of the grinding table 1 to be in a stretched state.
[0030] The compression of the first spring 12 and the stretching of the second spring 16 can buffer the buffer plate 8. The buffer plate 8 is subjected to the buffering force, which will buffer the bearing rollers that impact the buffer plate 8, reduce the falling speed of the bearing rollers, and prevent the bearing rollers from being damaged by violent impact with other bearing rollers in the receiving box 19 when falling.
[0031] See Figure 1 and Figure 4 It can be seen that when collecting bearing rollers, the bearing rollers can be buffered by the cooperation of the buffer plate 8 with the upper connecting rod 13 and the lower connecting rod 9, so as to avoid damage to the bearing rollers due to excessive speed and violent impact with the receiving material when they fall.
[0032] A guide rail 17 is installed at the bottom of the grinding table 1. A sliding block 18 is slidably connected inside the guide rail 17. A receiving box 19 is connected between two sets of sliding blocks 18. A rubber ball 20 is installed inside the sliding block 18 through a groove. A wedge block 21 that penetrates the sliding block 18 is connected to one side of the rubber ball 20. A top rod 22 that penetrates the guide rail 17 is provided on one side of the wedge block 21. A telescopic rod 23 is provided on one side of the receiving box 19. A return spring 24 is installed inside the telescopic rod 23. The telescopic rod 23 is installed at the bottom of the grinding table 1.
[0033] In practical implementation, when the bearing roller end face grinding discharge device needs to collect the bearing rollers in the receiving box 19, it is only necessary to press the push rods 22 on both sides of the guide rail 17 into the interior of the guide rail 17, so that the push rods 22 press the wedge block 21 on one side of the sliding block 18 into the sliding block 18. At this time, the wedge block 21 is not stuck in the groove of the guide rail 17. Then the return spring 24 in the telescopic rod 23 will return to its original position. Since the receiving box 19 is not limited by the wedge block 21, the receiving box 19 will move to one side along the guide rail 17 through the return action of the telescopic rod 23, so as to collect the bearing rollers in the receiving box 19 quickly and conveniently.
[0034] Conversely, by simply sliding the sliding blocks 18 on both sides of the receiving box 19 to the bottom of the discharge port 7 via the guide rail 17, the telescopic rod 23 is compressed, causing the return spring 24 inside the telescopic rod 23 to be compressed by the inner wall of the guide rail 17. At this time, the wedge block 21 will retract into the groove of the sliding block 18 and compress the rubber ball 20 in the groove. When the wedge block 21 moves to the groove on one side of the guide rail 17, the rubber ball 20 will reset, thereby squeezing the wedge block 21 out of the groove of the sliding block 18 and inserting the wedge block 21 into the groove of the guide rail 17. At this time, the receiving box 19 will be limited in the guide rail 17 by the limiting effect of the wedge block 21, so that the receiving box 19 can be stably set at the bottom of the discharge port 7.
[0035] See Figures 1-3 It is understood that when it is necessary to collect the bearing rollers in the receiving box 19, the wedge block 21 is pressed into the groove of the sliding block 18 by the push rod 22, and then the receiving box 19 will be pushed to one side along the guide rail 17 by the resetting action of the telescopic rod 23 and the return spring 24, so as to facilitate the collection of the bearing rollers in the receiving box 19.
[0036] In summary: This bearing roller end face grinding discharge device grinds the end face of bearing rollers by placing the bearing rollers on the storage tray 5 and then relying on the grinding equipment on the grinding table 1 to grind the end face of the bearing rollers. After grinding, the drive motor 2 is started, and the drive motor 2 drives the screw sleeve 4 to slide through the lead screw 3. The screw sleeve 4 causes the storage tray 5 to slide along the grinding table 1. When the storage tray 5 slides to the bottom of the fixed block 6, the storage tray 5 continues to move forward. Since the position of the fixed block 6 remains unchanged, the bearing rollers on the storage tray 5 are pushed down by the blocking effect of the fixed block 6 and finally fall into the receiving box 19 at the bottom through the discharge port 7, thus completing the discharge of the bearing rollers. This is the characteristic of the use of this bearing roller end face grinding discharge device. The contents not described in detail in this description are existing technologies known to those skilled in the art.
