Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to a double-sided pressure cap device for bearings. Background Technology

[0002] The use of bearings is affected by various factors, one of which is the end cap. Some bearings do not require end caps under certain conditions, but a large proportion of bearings require end caps for further protection. The functions of bearing end caps are twofold: to prevent impurities from entering and to ensure that lubricant does not overflow due to the rotation of the balls in the bearing, thus maximizing the lubrication provided by the lubricant. Bearing end caps are sometimes made of rubber and sometimes of metal. Pressing in rubber or metal end caps requires two sets of pressing equipment, resulting in poor compatibility and failing to meet usage requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a double-sided pressure cap device for bearings, which can solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A double-sided capping device for bearings includes a worktable, a feeding track disposed on the worktable, and a bearing transfer mechanism disposed in the same direction as the feeding track. The bearing transfer mechanism transfers the bearings on the feeding track at equal intervals so that they travel on the feeding track.

[0010] When the bottom plate of the cap moves left and right along the transverse guide rail, one of its discharge holes aligns with the step hole on the corresponding loading plate. The discharge sleeve covers the step hole. When the loading plate moves back and forth, the step hole on it moves between the corresponding discharge hole and the plastic cap removal and pressing mechanism or the iron cap removal and pressing mechanism.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1-6 As shown, this utility model provides a double-sided capping device for bearings, including a worktable 1, a feeding track 2 disposed on the worktable 1, and a bearing transfer mechanism disposed in the same direction as the feeding track 2. The bearing transfer mechanism transfers the bearings on the feeding track 2 at equal intervals so that they can travel on the feeding track 2. The feeding track 2 is provided with a first-sided capping mechanism 11, a first-sided inspection mechanism 21, a bearing flipping mechanism 3, a second-sided capping mechanism 12, and a second-sided inspection mechanism 22 in sequence. The bearing transfer mechanism and the bearing flipping mechanism are existing technologies and will not be described in detail here.

[0024] The first-side capping mechanism 11 and the second-side capping mechanism 12 both include a capping frame 101 located above the feeding track 2, a plastic cap removal and capping mechanism 102 and an iron cap removal and capping mechanism 103 arranged side by side on the capping frame 101, and a plastic cap feeding mechanism 104 and an iron cap feeding mechanism 105 located behind the feeding track 2 and opposite to the plastic cap removal and capping mechanism 102 and the iron cap removal and capping mechanism 103, respectively.

[0025] The first cover inspection mechanism 21 and the second cover inspection mechanism 22 both include a photoelectric detection head 201, an iron cover pressure boosting head 202, and an iron cover height detection head 203 arranged side by side above the feeding track 2. The photoelectric detection head 201 is driven by a photoelectric detection cylinder 204 to move up and down. The photoelectric detection cylinder 204 is mounted on a photoelectric detection seat 205. The iron cover pressure boosting head 202 is driven by an iron cover pressure boosting cylinder 206 to move up and down. The iron cover pressure boosting cylinder 206 is mounted on an iron cover pressure boosting seat 207. The iron cover height detection head 203 is driven by an iron cover height detection cylinder 208 to move up and down. The iron cover height detection cylinder 208 is mounted on an iron cover height detection seat 209. The photoelectric detection seat 205, the iron cover pressure boosting seat 207, and the iron cover height detection seat 209 are all mounted on the workbench 1.

[0026] When this utility model is in operation, if it is necessary to press rubber caps on both ends of the bearing, the bearing is moved under the drive of the bearing transfer mechanism to the bottom of the rubber cap removal and pressing mechanism 102 of the first pressing mechanism 11. Then, the rubber cap feeding mechanism 104 of the first pressing mechanism moves the rubber cap to the bottom of the rubber cap removal and pressing mechanism 102. Then, the rubber cap removal and pressing mechanism 102 removes the rubber cap and presses it on one end face of the bearing. Then, the bearing is moved under the drive of the bearing transfer mechanism, passing over the iron cap removal and pressing mechanism, and is moved to the bottom of the photoelectric detection head 201 of the first detection mechanism 21. The photoelectric detection head moves down under the drive of the photoelectric detection cylinder 204, and then detects whether the rubber cap on the bearing is in place, whether it is deformed, or whether it is reversed. If it is not qualified, the bearing is not flipped over or pressed with a second rubber cap, and is conveyed to the rejection station for rejection. If qualified, the bearing, driven by the bearing transfer mechanism, passes over the iron cover pressure head and the iron cover height detection head and is moved to the bearing flipping mechanism 3. The bearing flipping mechanism 3 flips the bearing so that the side with the rubber cover is facing down and the other side is facing up. Then, driven by the bearing transfer mechanism, the bearing moves to below the rubber cover removal and pressing mechanism 102 of the second pressing mechanism 12. Then, the rubber cover feeding mechanism 104 of the second pressing mechanism moves the rubber cover to below the rubber cover removal and pressing mechanism 102. Then, the cap removal and pressing mechanism 102 removes the cap and presses it onto the other end face of the bearing. The bearing, driven by the bearing transfer mechanism, then moves past the cap removal and pressing mechanism to below the photoelectric detection head 201 of the second detection mechanism 22. The photoelectric detection head 201, driven by the photoelectric detection cylinder 204, moves downwards to detect whether the cap on the bearing is in place, deformed, or reversed. If it fails, it is conveyed to the rejection station for rejection. If it passes, the bearing, driven by the bearing transfer mechanism, moves past the cap booster head and cap height detection head to the next processing step.

[0027] The pressing process of the iron cap is similar to that of the rubber cap. The iron cap feeding mechanism 105 and the iron cap removing and pressing mechanism 103 of the first pressing mechanism 11 work together to press the iron cap onto one end face of the bearing. Then, the photoelectric detection head 201 of the first detection mechanism 21 detects the presence, deformation, and reversed state of the iron cap on the bearing. If it fails, it is rejected. If it passes, the bearing is transported to the area below the iron cap pressurizing head 202. Driven by the iron cap pressurizing cylinder 206, the pressurizing head 202 moves downward and presses the iron cap again to ensure it is properly pressed. Then, the bearing is transported to the area below the iron cap height detection head 203. The height detection head 203 detects the height of the iron cap to determine if it is properly pressed. If it fails, it is rejected. If it passes, the bearing is transported to the bearing flipping mechanism 3. The bearing is flipped over, and then the iron cover feeding mechanism 105 and the iron cover removal and pressing mechanism 103 of the second pressing mechanism 12 cooperate to press the iron cover onto the other end face of the bearing. Then, the photoelectric detection head 201 of the second detection mechanism 22 detects the presence, deformation, and reversed cover of the iron cover on the bearing. If it is unqualified, it will be rejected. If it is qualified, the bearing is transported to the bottom of the iron cover pressure head 202. The iron cover pressure head 202 moves down under the drive of the iron cover pressure cylinder 206 and presses the iron cover again to ensure that the iron cover is pressed in place. Then, the bearing is transported to the bottom of the iron cover height detection head 203. The iron cover height detection head 203 detects the height of the iron cover to determine whether it is pressed in place. If it is unqualified, it will be rejected. If it is qualified, the bearing is moved to the next process under the drive of the bearing transfer mechanism.

[0028] This invention eliminates all processes related to the metal cap during the pressing of the rubber cap, and vice versa. The two processes cannot operate simultaneously; however, the control system can switch between the feeding, unloading, and pressing processes of the metal cap or the rubber cap with a single button press, as needed. This invention features four sets of cap-unloading and pressing mechanisms and a feeding mechanism: two sets for feeding and pressing the metal caps at both ends of the bearing, and two sets for feeding and pressing the rubber caps at both ends of the bearing. This allows for switching between the two cap types, meeting usage requirements and saving costs.

[0029] Preferably, a feeding seat 1001 is provided behind the feeding track 2, and a transverse guide rail 1002 is provided on the feeding seat 101. Both the rubber cover feeding mechanism 104 and the iron cover feeding mechanism 105 include a feeding plate 1003 and a cover bottom plate 1004.

[0030] Two feeding plates 1003 are slidably disposed side by side in the feeding seat 1001. The upper end surfaces of the two feeding plates 1003 are flush with the upper end surface of the feeding seat 1001. Each of the two feeding plates 1003 is provided with a stepped hole 1005 for placing a single bearing end cap. The two feeding plates 1003 are driven by their respective feeding drive mechanisms to move back and forth.

[0031] Two bottom plates 1004 are slidably mounted side by side on the transverse guide rail 1002. The two bottom plates 1004 are driven by their respective material changing drive mechanisms to move left and right along the transverse guide rail 1002. Each bottom plate 1004 is provided with two material dropping holes 1006. Each material dropping hole 1006 has a material dropping sleeve 1007 extending downward from its periphery to contact the upper end face of the feeding seat or feeding plate. Each material dropping hole 1006 is provided with a top plate rod 1008 above it. The upper ends of the two top plates rods are mounted side by side on a top plate 1009. The top plate 1009 is fixed to the bottom plate 1004 by a top plate column 1010.

[0032] When the bottom plate 1004 moves left and right along the transverse guide rail 1002, one of its discharge holes 1006 is aligned with the corresponding stepped hole 1005 on the feed plate 1003. The discharge sleeve 1007 covers the stepped hole 1005. When the feed plate 1003 moves back and forth, the stepped hole 1005 moves between the corresponding discharge hole 1006 and the plastic cap removal and pressing mechanism 102 or the iron cap removal and pressing mechanism 103.

[0033] In this invention, during material feeding, a rubber cap is threaded onto the cap-stringing rod 1008 of the rubber cap feeding mechanism 104, and an iron cap is threaded onto the cap-stringing rod 1008 of the iron cap feeding mechanism 105. The feeding process for both rubber and iron caps is the same. The last rubber cap (or iron cap) on the cap-stringing rod 1008 falls into the stepped hole 1005 of the feeding plate 1003 through the dropping hole 1006 and the dropping sleeve 1007. The bearing, driven by the feeding track, moves to below the corresponding rubber cap removal and pressing mechanism (or iron cap removal and pressing mechanism). The rear loading drive mechanism moves the loading plate 1003 forward, so that the rubber cap (iron cap) on the loading plate 1003 is positioned below the corresponding rubber cap removal and pressing mechanism (iron cap removal and pressing mechanism). The rubber cap removal and pressing mechanism removes the rubber cap (iron cap) from the loading plate. Then, the loading drive mechanism moves the loading plate 1003 backward, and the rubber cap removal and pressing mechanism presses the rubber cap (iron cap) into the bearing, thus realizing the loading, removal, and pressing of the rubber cap (iron cap). If the rubber cap (iron cap) on one of the cap-stringing rods 1008 is assembled, the material changing drive mechanism can move the cap-stringing base plate 1004 so that the other cap-stringing rod 1008 with a rubber cap (iron cap) is opposite the loading plate 1003.

[0034] Preferably, the feeding drive mechanism includes a feeding drive cylinder 1011 mounted on the workbench 1. The output end of the feeding drive cylinder 1011 is connected to the rear end of the corresponding feeding plate 1003. Two longitudinal guide rails 1012 are arranged side by side on the workbench 1. Each feeding plate 1003 has a longitudinal slider on its lower side that cooperates with the longitudinal guide rail 1012. The feeding drive cylinder 1011 drives the feeding plate 1003 to move back and forth. The longitudinal slider on the feeding plate 1003 moves back and forth along the longitudinal guide rail 1012. The feeding plate 1003 moves back and forth smoothly.

[0035] Preferably, the stepped hole 1005 is equipped with a material detection sensor, which can detect whether there is material (plastic cover or iron cover) in the stepped hole 1005. If there is no material, the next step is not allowed and an alarm is triggered. If there is material, the next step is performed.

[0036] Preferably, the material changing drive mechanism includes a material changing drive cylinder 1013 mounted on the loading seat 1001. The output end of the material changing drive cylinder 1013 is vertically provided with a pull rod 1014. The end of the pull rod 1014 is fixed to the middle of the corresponding string cover bottom plate 1004. The bottom of the string cover bottom plate 1004 is provided with a transverse sliding block 1015 that cooperates with the transverse guide rail 1002. The material changing drive cylinder 1013 drives the pull rod 1014 to move, and the pull rod drives the string cover bottom plate 1004 to move left and right. The transverse sliding block 1015 on the string cover bottom plate moves left and right along the transverse guide rail 1002, and the string cover bottom plate 1004 moves smoothly left and right.

[0037] Preferably, both the plastic cap removal and pressing mechanism 102 and the iron cap removal and pressing mechanism 103 include a cap removal and pressing cylinder 1016 fixed on the pressing frame 101. The output end of the cap removal and pressing cylinder 1016 is provided with a pressing seat 1017. A cap removal core 1018 is vertically movably provided in the pressing seat 1017. The lower end of the cap removal core 1018 extends out of the pressing seat 1017. A spring is provided between the upper end of the cap removal core 1018 and the pressing seat 1017. A guide post 1019 is vertically provided on the pressing seat. A guide sleeve 1020 is vertically provided on the pressing frame 101. The guide post 1019 is slidably disposed in the guide sleeve 1020. The capping and pressing processes for both the rubber cap and the iron cap in this invention are the same. The bearing, conveyed by the feeding track 2, is positioned directly below the capping core 1018. Then, the stepped hole 1005 of the feeding plate 1003, carrying the rubber cap (iron cap), is positioned between the capping core 1018 and the bearing. Next, the capping and pressing cylinder 1016 moves the pressing seat 1017 and the capping core 1018 downwards, allowing the rubber cap (iron cap) to fit over the capping core 1018. Then, the capping and pressing cylinder 1016 moves the capping core 1018 upwards, completing the feeding process. Plate 1003 returns to its original position, and then the cap removal and pressing cylinder 1016 drives the pressing seat 1017 and the cap removal core 1018 to move down again. The cap removal core 1018 is inserted into the bearing and continues to move down. Under the action of the bearing, the cap removal core 1018 moves up, the spring is compressed, and the pressing seat 1017 removes the plastic cap (iron cap) from the cap removal core 1018 and presses it on the end face of the bearing. Then the cap removal and pressing cylinder 1016 drives the pressing seat 1017 and the cap removal core 1018 to move up, thereby realizing the cap removal and pressing action of the plastic cap (iron cap).
