Technical Field

[0001] This invention relates to the field of bearing component processing technology, specifically to a testing device and method for testing bearing rollers used in speed reducers. Background Technology

[0002] Gear reducers are the most widely used transmission devices in industrial enterprises, and the quality of the bearings on each shaft of the gear reducer is crucial to its continuous and stable operation. To ensure the gear reducer can operate continuously and stably, the surface smoothness of the bearings needs to be tested, thereby improving the service life of the gear reducer and avoiding the costs associated with frequent bearing replacements.

[0003] One type of bearing used in speed reducers is the rolling bearing, a widely used component in modern machinery. It supports rotating parts by relying on the rolling contact between the main components. Most rolling bearings use cylindrical rollers. During the production process of bearing rollers, defect detection is required to ensure the quality of the finished product. Existing speed reducer bearing detection devices cannot automatically reject defective products after inspection, leading to increased labor costs. Furthermore, the clamping device of the detection device cannot be adjusted according to the bearing diameter and inner diameter of different sizes, resulting in insufficient adjustability.

Two fixed magnetic plates are fixedly connected to the bottom inner wall of the good product channel.

[0013] Preferably, the method of using the detection device for bearing rollers of a speed reducer includes the following steps: S1. First, turn the gear lever according to the inner diameter of the bearing roller to make the small gear rotate. The large gear meshing with the small gear rotates synchronously. The rotating large gear drives the clamping slide rods in the movable slide plate to move inward or outward. At the same time, the inner diameter arc plates at the top of the five clamping slide rods move inward and outward simultaneously to adjust the support size of the inner diameter. Then, turn the adjustment lever to make the inner square frame at the top of the clamping shaft move in the same direction. As the inner square frame rotates, the four tension bushings on the side also begin to pull the bent rod and the linkage bushing. The four opposing clamping frames pull the clamping frames on the same side to slide along the slide opening of the detection tray. During the adjustment process, when the movable slide moves, the diameter of the movable electric plate and the detection arc plate at the bottom are also adjusted. S2. According to the same batch of bearing rollers After the diameter adjustment, the main rotating machine and the detection motor are started. The active rotating tooth at the other end of the main rotating machine, while starting, drives the left rotating tooth via a power belt. The rotating left rotating tooth sequentially drives the lower short rod, the Z-shaped rod, and the upper short rod to operate together. Then, the right rotating tooth on the side surface of the lower lifting rod drives the driven gear in the second lifting assembly, which has the same structure, to rotate together via a driven belt. As the first and second lifting assemblies operate, the U-shaped plate at the top of the Z-shaped rod begins to push the lifting door frame up and down. When the lifting door frame is raised, it engages with the inner wall of the conveyor belt, causing the conveyor belt to move intermittently. S3. Simultaneously, as the main rotating machine rotates, the series shaft and series rotating tooth connected to the main rotating machine rotate, located on the T-shaped rod... The tandem rotating teeth at one end drive the first double-tooth rotating rod above to rotate via a tandem belt. The gear at the other end of the first double-tooth rotating rod causes the second double-tooth rotating rod to rotate via a transmission belt. Then, the gear at the other end of the second double-tooth rotating rod meshes with the upper linkage gear and the middle gear above, thereby causing the side bottom gears and half gears on both sides of the middle gear to rotate. Due to the structure of the two half gears themselves, the reciprocating worm gear between the two half gears will reciprocate up and down along the sleeve, and the extension slide fixedly connected to the side surface of the reciprocating worm gear will move up and down accordingly. S4. Since the detection motor is in the starting state, the square plate, column and detection tray will always be in a rotating state. Whenever the extension slide falls, the detection arc plate will clamp the outer surface of the bearing roller. Only when the bearing roller... When the outer surface is uneven, the movable electric plate located at the top of the detection arc plate moves back and forth between the two fixed electric plates. Only when the defect of the test piece does not meet the error standard will the movable electric plate in the two fixed electric plates contact and trigger the current. At the same time, the current is transmitted along the fixed wire on the upper surface of the line pipe to the top ring and then to the extension box. Then it is transmitted to the inclined frame rod by the tension wire. Under the power drive, the material distribution shaft rod connected to the material distribution plate rotates, revealing the defective product channel below. The movable magnetic plates located on both sides of the material distribution plate are magnetically attracted to the fixed magnetic plates. After the defective products are classified, due to the tension of the return spring, there will be a slow pull-back time to ensure that the next qualified product can enter the good product channel, thus completing the detection and classification of different models of bearing rollers.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the linkage between the main power component and the lifting component enables the lifting frame to move up and down, thereby allowing the conveyor belt to move forward intermittently, providing corresponding detection time for the inspection of bearing rollers.

[0015] In this invention, the linkage gear structure of the main power component and the series gear component increases the extension of power operation under a single power state, improves the effective utilization of the power source, and the whole device saves energy and reduces emissions. Furthermore, the automatic detection purpose is achieved through the conversion of multiple sets of gears to lift and pull up the detection device.

[0016] In this invention, the clamping device on the conveyor belt and the adjustment structure inside the detection device can be adjusted according to the diameter of the rollers in different batches, thereby expanding the scope of use of the equipment and increasing its versatility. In addition, the spring structure inside the detection device provides a certain detection error for the rollers and prevents false triggering.

[0017] In this invention, multiple sets of equipment are driven in batches by a power structure, providing power to both the conveying and reciprocating components. This enables the equipment to save energy and reduce emissions, and also allows for automatic defect detection of the rollers within a certain range. After detection, the rollers are automatically sorted, integrating clamping, detection, and sorting functions. The device has more and more functions and its application range is expanded.

[0029] A method for using a testing device for bearing rollers in a speed reducer includes the following steps: S1. First, according to the inner diameter of the bearing roller, turn the gear lever 8010 to make the pinion 808 rotate. The large gear 807 meshing with the pinion 808 rotates synchronously. The rotating large gear 807 drives the clamping slide rods 804 in the movable slide plate 803 to move inward or outward. At the same time, the inner diameter arc plates 805 at the top of the five clamping slide rods 804 move inward and outward simultaneously to adjust the support size of the inner diameter. Then, turn the adjusting lever 1212 to make the inner square frame 1202 at the top of the clamping shaft 1201 move in the same direction. As the inner square frame 1202 rotates, the four tension bushings 12 located on the side... 03 also begins to pull the bent rod 1204 and the linkage sleeve 1205, while the four opposing clamping frames 1206 pull the clamping frames 1206 on the same side to slide along the slide opening of the detection tray 1105. During the adjustment process, when the movable slide 1208 moves, the movable electric plate 1210 and the bottom detection arc plate 1211 are also adjusted in diameter; S2, after adjusting the diameter according to the same batch of bearing rollers, the main rotating machine 302 and the detection motor 1102 are started. The active rotating gear 305 at the other end of the main rotating machine 302 drives the left rotating gear 402 to rotate through the power belt 306. The rotating left rotating gear 402 drives the lower short rod 404, Z-shaped rod 405 and upper short rod 404 in sequence. 06. Working together, the right-hand rotating tooth 403 on the side surface of the lower lifting rod 401 drives the driven gear 4010 in the second lifting assembly 5, which has the same structure, to rotate together via the driven belt 409. As the first lifting assembly 4 and the second lifting assembly 5 operate, the U-shaped plate 408 at the top of the Z-shaped rod 405 begins to push the lifting door frame 6 up and down. When the lifting door frame 6 is lifted, it engages with the inner wall of the conveyor belt 7, at which time the conveyor belt 7 begins to move intermittently; S3. At the same time, when the main rotating machine 302 rotates, the series shaft rod 901 and series rotating tooth 902 connected to the main rotating machine 302 rotate, and the series rotating tooth 902 located at the bottom end of the T-shaped rod 903 rotates. The gear 902 drives the first double-tooth rotating rod 904 above to rotate via the series belt 905. The gear at the other end of the first double-tooth rotating rod 904 causes the second double-tooth rotating rod 907 to rotate via the transmission belt 906. Then, the gear at the other end of the second double-tooth rotating rod 907 meshes with the upper linkage gear 908 and the middle gear 909 above, thereby causing the side bottom gears 9010 and half gears 9011 on both sides of the middle gear 909 to rotate. Due to the structure of the two half gears 9011, the reciprocating worm gear 9012 between the two half gears 9011 will reciprocate up and down along the sleeve 9013. The extension slide 1101 fixedly connected to the side surface of the reciprocating worm gear 9012 moves up and down accordingly.S4. Because the detection motor 1102 is in the starting state, the square plate 1103, column 1104, and detection tray 1105 will remain in a rotating state. Whenever the extension carriage 1101 falls, the detection arc plate 1211 will clamp the outer surface of the bearing roller. Only when the outer surface of the bearing roller is uneven will the movable electric plate 1210 at the top of the detection arc plate 1211 move back and forth within the two fixed electric plates 1207. And only when the defect of the test piece does not meet the error standard will the movable electric plate 1210 within the two fixed electric plates 1207 contact and trigger the current. At the same time, the current flows along the line conduit 110. The fixed wire 1213 on the upper surface transmits power to the top ring 1108 and then to the extension box 1107. From there, the tension wire 1109 transmits power to the inclined support rod 1404. Driven by electricity, the sorting shaft 1405, connected to the sorting plate 1406, rotates, exposing the defective product channel 1403 below. The movable magnetic plates 1407 on both sides of the sorting plate 1406 are magnetically attracted to the fixed magnetic plates 1409, sorting the defective products. Due to the tension of the return spring 1408, there is a delayed pull-back time to ensure that the next qualified product can enter the good product channel 1402, completing the different model detection and sorting of the bearing rollers.

9. A method of using a testing device for bearing rollers of a speed reducer, comprising using the testing device for bearing rollers of a speed reducer as described in any one of claims 1-8, characterized in that, The steps include: S1. First, turn the gear lever (8010) according to the inner diameter of the bearing roller to make the pinion (808) rotate. The large gear (807) meshing with the pinion (808) rotates synchronously. The rotating large gear (807) drives the clamping slide rod (804) in the movable slide plate (803) to move inward or outward. At the same time, the inner diameter arc plates (805) at the top of the five clamping slide rods (804) move inward and outward simultaneously to adjust the support size of the inner diameter. Then, turn the adjusting handle (1212) to adjust the support size of the inner diameter. This causes the inner square frame (1202) at the top of the clamping shaft (1201) to move in the same direction. As the inner square frame (1202) rotates, the four tension bushings (1203) on the side also begin to pull the bent rod (1204) and the linkage bushing (1205). Meanwhile, the four opposing clamping frames (1206) pull the clamping frames (1206) on the same side to slide along the slide opening of the detection tray (1105). During the adjustment process, when the movable slide (1208) moves, the movable electric plate (1210) is moved. The diameter of the bottom detection arc plate (1211) is adjusted in the same way; S2, after adjusting the diameter according to the same batch of bearing rollers, the main rotating machine (302) and the detection motor (1102) are started. The active rotating tooth (305) at the other end of the main rotating machine (302) drives the left rotating tooth (402) to rotate through the power belt (306). The rotating left rotating tooth (402) drives the lower short rod (404), Z-shaped rod (405) and upper short rod (406) to work together in sequence. Then the lower lifting rod ( 401) The right-hand tooth (403) on the side surface drives the driven gear (4010) in the second lifting assembly (5) with the same structure to rotate together via the driven belt (409). As the first lifting assembly (4) and the second lifting assembly (5) operate, the U-shaped plate (408) at the top of the Z-shaped rod (405) begins to push the lifting door frame (6) up and down. When the lifting door frame (6) is lifted, it will mesh with the inner wall of the conveyor belt (7). At this time, the conveyor belt (7) begins to move intermittently.S3. Simultaneously, when the main rotating machine (302) rotates, the series shaft (901) and series rotating gear (902) connected to the main rotating machine (302) rotate. The series rotating gear (902) located at the bottom end of the T-shaped rod (903) drives the upper first double-tooth rotating rod (904) to rotate through the series belt (905). The gear at the other end of the first double-tooth rotating rod (904) causes the second double-tooth rotating rod (907) to rotate through the transmission belt (906). Then, the gear at the other end of the second double-tooth rotating rod (907) meshes with the upper linkage upper gear (908) and the middle gear (909) to drive the upper linkage upper gear (908) and the middle gear (909). This causes the side bottom teeth (9010) and half gears (9011) on both sides of the center tooth (909) to rotate. Due to the structure of the two half gears (9011), the reciprocating worm gear (9012) between the two half gears (9011) will reciprocate up and down along the sleeve (9013), and the extension slide (1101) fixedly connected to the side surface of the reciprocating worm gear (9012) will move up and down accordingly; S4, since the detection motor (1102) is in the starting state, the square plate (1103), column (1104) and detection tray (1105) will always be in a rotating state, whenever the extension When the carriage (1101) falls, the detection arc plate (1211) clamps the outer surface of the bearing roller. Only when the outer surface of the bearing roller is uneven, the movable electric plate (1210) at the top of the detection arc plate (1211) moves back and forth between the two fixed electric plates (1207). Only when the defect of the test piece does not meet the error standard will the movable electric plate (1210) in the two fixed electric plates (1207) contact and trigger the current. At the same time, the current is transmitted along the fixed wire (1213) on the upper surface of the line pipe (1106) to the top ring (1108) and then to the extension box ( 1107), and then the tension wire (1109) transmits the signal to the inclined frame rod (1404). Under electric drive, the material distribution shaft rod (1405) rotates along with the material distribution plate (1406), exposing the defective product channel (1403) below. The movable magnetic plates (1407) on both sides of the material distribution plate (1406) are magnetically attracted to the fixed magnetic plates (1409). After the defective products are classified, due to the tension of the return spring (1408), there will be a slow pull-back time to ensure that the next qualified product can enter the good product channel (1402), thus completing the detection and classification of different models of bearing rollers.
