[0002] Bearing rollers are widely used in many fields, including but not limited to the following industries: mining conveying equipment, power industry and building materials industry.

[0003] Chinese patent document CN201310404824.0 discloses a quick bearing installation device for idler rollers, including a base with a fitting mold on the base and a top mold on the same center line as the fitting mold. The top mold is driven by a drive device to move up and down along the center line of the fitting mold. However, the above-mentioned bearing installation device can only install bearings on one side of the idler roller. To install bearings on the other side, the idler roller needs to be removed, flipped, and then the other side needs to be installed. The installation procedure of the above-mentioned installation device is complex and has low production efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a roller bearing assembly machine, which aims to solve the technical problem that the existing bearing installation device can only install bearings on one side of the roller at a time. When installing bearings on the other side, the roller needs to be taken out and flipped before the other side can be installed, which leads to a complicated installation procedure and low production efficiency.

[0005] This utility model provides a roller bearing assembly machine, including a frame platform. The frame platform is equipped with a roller conveying mechanism, a bearing conveying mechanism, a clamping mechanism, and a pressing mechanism. Two pressing mechanisms are provided, located on opposite sides of the roller conveying mechanism and arranged sequentially along the conveying direction of the roller conveying mechanism. Two bearing conveying mechanisms are also provided, each corresponding to one of the ejector ends of the two pressing mechanisms. The bearing conveying mechanism is used to convey the bearing to the ejector end of the pressing mechanism. Two clamping mechanisms are also provided, each corresponding to one of the ejector ends of the two pressing mechanisms. The clamping mechanism is used to apply pressure along the radial direction of the roller to press it. The roller conveying mechanism is used to sequentially convey the roller to positions corresponding to the two pressing mechanisms, so that the pressing mechanism can press the bearing into the roller along the axial direction of the roller.

[0006] Furthermore, the idler roller conveying mechanism includes a drive motor, a drive sprocket, a driven sprocket, a transmission chain, and a support seat. The drive motor is mounted on the frame platform, the drive sprocket is mounted on the output shaft of the drive motor, the driven sprocket is rotatably connected to the frame platform, the support seat is mounted on the transmission chain, the support seat is used to support the idler roller, and the transmission chain is wound around the drive sprocket and the driven sprocket.

[0007] Furthermore, the pressing mechanism includes a lifting cylinder, a lifting seat, an upper clamping member, and a side clamping member. The lifting seat is located on the lifting end of the lifting cylinder. The lifting cylinder, the upper clamping member, and the side clamping member are all located on the machine frame. The upper clamping member is located on the side away from the lifting seat. The bearing seat has a recessed groove for accommodating the idler roller. The bottom of the groove has a through hole through which the lifting seat can pass. The lifting seat is used to pass through the through hole and cooperate with the upper clamping member to press the idler roller in the radial direction. The side clamping member is located on the side away from the pressing mechanism and is used to support the idler roller in the axial direction.

[0008] Furthermore, the bearing conveying mechanism includes a first guide groove, a second guide groove, a first blocking cylinder, a second blocking cylinder, and a guide member. The first guide groove is vertically arranged on the machine frame. The guide member is located at the bottom of the first guide groove and is used to receive the bearing in the first guide groove for pressing by the ejector end of the pressing mechanism. The second guide groove communicates with the first guide groove and is inclined. Both the first and second guide grooves can accommodate bearings. The first blocking cylinder is located on the first guide groove, and the ejector end of the first blocking cylinder is provided with a first limiting rod. The first limiting rod is used to block the bearing in the first guide groove. The second blocking cylinder is located at one end of the first guide groove adjacent to the second guide groove, and the ejector end of the second blocking cylinder is provided with a second limiting rod. The second limiting rod is used to block the bearing in the second guide groove.

[0009] Furthermore, a limiting plate is hinged to the bottom of the first guide groove on the side away from the pressing mechanism. The limiting plate is connected to a torsion spring, which is used to drive the limiting plate to flip over to press the bearing.

[0010] Furthermore, the pressing mechanism includes a pressing cylinder and a pressing shaft. The pressing cylinder is mounted on the machine frame, and the pressing shaft is mounted on the power output end of the pressing cylinder. The pressing cylinder is used to push the pressing shaft out to press the bearing into the roller along the axial direction of the roller.

[0011] Furthermore, it also includes a receiving mechanism, which is located on the machine frame and is used to collect the pressed idler rollers.

[0012] Beneficial effects: This utility model provides a roller bearing assembly machine, including a frame, on which are provided a roller conveying mechanism, a bearing conveying mechanism, a clamping mechanism, and a pressing mechanism. Since there are two bearing conveying mechanisms, clamping mechanisms, and pressing mechanisms, and they are correspondingly arranged on both sides of the roller conveying mechanism, the roller bearing assembly machine can complete the installation of the bearings on both sides in sequence during the transmission process of the roller conveying mechanism. There is no need to manually remove and flip the rollers, which simplifies the installation method in the prior art and thus improves production efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figures 1 to 5 This utility model provides a roller bearing assembly machine, including a frame 1. The frame 1 is provided with a roller conveying mechanism 2, a bearing conveying mechanism 3, a pressing mechanism 4, and a pressing mechanism 5. There are two pressing mechanisms 5, which are respectively located on both sides of the roller conveying mechanism 2 and are arranged sequentially along the conveying direction of the roller conveying mechanism 2. There are also two bearing conveying mechanisms 3, which are correspondingly arranged on the ejector ends of the two pressing mechanisms 5. The bearing conveying mechanism 3 is used to convey the bearing 9 to the ejector end of the pressing mechanism 5. There are also two pressing mechanisms 4, which are correspondingly arranged on the ejector ends of the two pressing mechanisms 5. The pressing mechanism 4 is used to apply pressure along the radial direction of the roller 8 to press the roller 8. The roller conveying mechanism 2 is used to sequentially convey the roller 8 to the positions corresponding to the two pressing mechanisms 5, so that the pressing mechanism 5 can press the bearing 9 into the roller 8 along the axial direction of the roller 8.

[0021] Specifically, the idler roller 8 without the bearing 9 installed is placed on the idler roller conveying mechanism 2 by manual labor or a gripping device. The idler roller conveying mechanism 2 then sequentially conveys the idler roller 8 to the positions corresponding to the two pressing mechanisms 5. The pressing mechanisms 5 then press the bearing 9 into the idler roller 8 along its axial direction. After pressing is completed, the idler roller conveying mechanism 2 continues to convey the idler roller 8 with the bearing 9 installed forward, where workers or gripping devices remove the idler roller 8.

[0022] In one feasible embodiment, the idler roller conveying mechanism 2 includes a drive motor 21, a drive sprocket 22, a driven sprocket 23, a transmission chain 24, and a support seat 25. The drive motor 21 is mounted on the frame 1, the drive sprocket 22 is mounted on the output shaft of the drive motor 21, the driven sprocket 23 is rotatably connected to the frame 1, and the support seat 25 is mounted on the transmission chain 24. The support seat 25 is used to support the idler roller 8, and the transmission chain 24 is wound around the drive sprocket 22 and the driven sprocket 23. In this embodiment, the drive motor 21 drives the drive sprocket 22 to rotate, which in turn drives the support seat 25 to move. Further, several support seats 25 are provided, and these support seats 25 are arranged along the extension direction of the transmission chain 24. Since the transmission chain 24 is wound around the drive sprocket 22 and the driven sprocket 23, the several support seats 25 reciprocate under the drive of the transmission chain 24. When the drive chain 24 drives the carrier seat 25 to rotate to a position where the carrier seat 25 is above the drive chain 24, the idler roller 8, whose bearing 9 has not yet been installed, is placed on the carrier seat 25 manually or by a gripping device.

[0023] In one feasible embodiment, the pressing mechanism 4 includes a lifting cylinder 41, a lifting seat 42, an upper clamping member 43, and a side clamping member 44. The lifting seat 42 is disposed on the lifting end of the lifting cylinder 41. The lifting cylinder 41, the upper clamping member 43, and the side clamping member 44 are all disposed on the machine frame 1. The upper clamping member 43 is located on the side away from the lifting seat 42. The bearing seat 25 is recessed with a groove 251 for accommodating the idler roller 8. The bottom of the groove 251 is provided with a through hole 252 through which the lifting seat 42 can pass. The lifting seat 42 is used to pass through the through hole 252 and cooperate with the upper clamping member 43 to press the idler roller 8 in the radial direction. The side clamping member 44 is located on the side away from the pressing mechanism 5. The side clamping member 44 is used to support the idler roller 8 in the axial direction. In this embodiment, the groove 251 can stably place the idler roller 8, facilitating conveying by the transmission belt. When the transmission belt conveys the carrier seat 25 to the position corresponding to the pressing mechanism 5, the lifting cylinder 41 is activated, lifting the lifting seat 42 upward (i.e., lifting the lifting seat 42 along the radial direction of the idler roller 8), cooperating with the upper clamping member 43 to press the idler roller 8 (at this time, the idler roller 8 is separated from the carrier seat 25), which can prevent the idler roller 8 from shifting when the pressing mechanism 5 presses the bearing 9 into the idler roller 8. At the same time, since the pressing mechanism 5 will generate a large force in the axial direction of the idler roller 8 when pressing the bearing 9 into the idler roller 8, the friction between the idler roller 8, the upper clamping member 43, and the lifting seat 42 is not enough to offset the above force. Therefore, the side clamping member 44 is needed to support the idler roller 8.

[0024] In one feasible embodiment, the bearing conveying mechanism 3 includes a first guide groove 31, a second guide groove 32, a first blocking cylinder 33, a second blocking cylinder 34, and a guide member 35. The first guide groove 31 is vertically arranged on the machine frame 1. The guide member 35 is located at the bottom of the first guide groove 31 and is used to receive the bearing 9 in the first guide groove 31 for pressing by the ejector end of the pressing mechanism 5. The second guide groove 32 communicates with the first guide groove 31 and is inclined. Both guide groove 31 and the second guide groove 32 can accommodate bearings 9. A first blocking cylinder 33 is disposed on the first guide groove 31, and a first limiting rod 331 is provided at the ejector end of the first blocking cylinder 33. The first limiting rod 331 is used to block the bearings 9 within the first guide groove 31. A second blocking cylinder 34 is disposed at one end of the first guide groove 31 adjacent to the second guide groove 32, and a second limiting rod 341 is provided at the ejector end of the second blocking cylinder 34. The second limiting rod 341 is used to block the bearings 9 within the second guide groove 32. In this embodiment, due to the inclined arrangement of the second guide groove, under the action of gravity, multiple bearings 9 within the second guide groove slide towards the second limiting rod 341. The specific working process of this embodiment is as follows: The first blocking cylinder 33 drives the first blocking rod to extend, and the second blocking cylinder 34 drives the second blocking rod to extend. At this time, there is no bearing 9 between the first and second blocking rods. The second blocking cylinder 34 drives the second blocking rod to retract. Under the action of gravity, the bearing 9 enters the first guide groove 31 from the second guide groove 32 and falls on the first blocking rod. The second blocking cylinder 34 drives the second blocking rod to extend to prevent the bearing 9 in the second guide groove 32 from continuing to slide down. The first blocking cylinder 33 drives the first blocking rod to retract. Under the action of gravity, the bearing 9 falls on the position corresponding to the pressing mechanism 5. The first blocking cylinder 33 drives the first blocking rod to extend, restoring the initial state. This process is repeated to continuously transport the bearing 9.

[0025] In one feasible embodiment, a limiting plate 36 is hinged to the bottom of the first guide groove 31 on the side away from the pressing mechanism 5. The limiting plate 36 is connected to a torsion spring 37, which drives the limiting plate 36 to flip and press the bearing 9. In this embodiment, to prevent the bearing 9 from falling to the position corresponding to the pressing mechanism 5 and tipping over, the limiting plate 36, under the elastic force of the torsion spring 37, supports the bearing 9, thereby preventing it from tipping over. When the pressing mechanism 5 presses the bearing 9 along the axial direction of the roller 8, the bearing 9 presses against the limiting plate 36, the limiting plate 36 flips upward, and the bearing 9 continues to slide. After pressing is completed, the pressing mechanism 5 retracts, and the limiting plate 36 returns to its original position under the elastic force of the torsion spring 37.

[0026] In one feasible embodiment, the pressing mechanism 5 includes a pressing cylinder 51 and a pressing shaft 52. The pressing cylinder 51 is mounted on the machine frame 1, and the pressing shaft 52 is mounted on the power output end of the pressing cylinder 51. The pressing cylinder 51 is used to push the pressing shaft 52 out to press the bearing 9 into the roller 8 along the axial direction of the roller 8.

[0027] In one feasible embodiment, a receiving mechanism 7 is also included, which is mounted on the frame 1 and is used to collect the pressed idler rollers 8. Specifically, the receiving mechanism 7 includes a guide rod 71 and a receiving trough 72. The guide rod 71 is inclinedly mounted on the frame 1 and located at the end of the conveyor belt in the conveying direction. The receiving trough 72 is located below the guide rod 71. It is worth noting that there are two guide rods 71, and the distance between the two guide rods 71 ​​is less than the length of the idler roller 8, thus effectively guiding the idler roller 8. When the conveyor belt drives the support seat 25 to flip downwards, the idler roller 8 falls off the support seat 25, and the guide rod 71 guides the fallen idler roller 8 into the receiving trough 72.

[0028] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
