Description

Technical Field

[0001] This application relates to the technical field of bearing processing, and particularly to a sealing and assembling device for bearing components. Background Art

[0002] A bearing mainly consists of an inner ring, an outer ring, rolling elements and a cage. Some bearings are pre-filled with lubricating oil inside. At the same time, in order to prevent the internal lubricating oil from leaking or prevent external dust from entering, a rubber sealing ring is generally fixed at the end face of the bearing.

[0003] Currently, in the sealing ring assembly technology of bearings, manual assembly or automatic assembly methods are generally used. In the manual assembly method, workers use simple tools such as tweezers and pliers to install the seals on the ends of bearing components one by one; this method is flexible in operation and can adapt to bearings of different specifications and shapes; however, the manual assembly method mainly relies on the experience and skills of workers, with low assembly efficiency and unstable assembly quality. When using automatic assembly, generally, the bearing is first sent below the sealing ring feeding mechanism, and the feeding mechanism installs the sealing ring on the bearing from top to bottom. Then, the bearing with one side installed is sent to the flipping mechanism through the conveying mechanism, and after flipping, the rubber ring is installed on the other side sealing ring; in this assembly method, since the conveying mechanism mostly uses a conveyor belt for conveying, during the movement of the bearing on the surface of the conveyor belt, due to the lack of positioning of the bearing, after being transported and processed through multiple processes, the problem of bearing displacement is likely to occur. Therefore, it is often necessary to adjust the position of the bearing during the processing.

[0004] In view of the above related technologies, in the current sealing ring assembly technology of bearings, manual assembly has wide applicability, but low efficiency and unstable assembly quality; the automatic assembly method will generate position deviations during the cooperation of multiple workstations, especially during the processing of miniature bearings, it is more difficult to achieve high-efficiency and precise assembly.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-7 This application is described in further detail.

[0029] The present application embodiment discloses a bearing element sealing assembly device. Figure 1 The assembly device includes a base 1, a positioning table 8 fixedly arranged on the base 1, a processing table 2 rotatably arranged on the base 1, and a driving assembly 3 for driving the processing table 2 to rotate. The base 1 provides a carrier for the installation of other structures, and the positioning table 8 is preferably configured as a circular table, which is mounted on the base 1 by means of supporting rods and can be fixed by bolts or the like. The processing table 2 is also configured as a circular table, which is arranged on the processing table 2 and rotated by the driving assembly 3.

[0030] A mounting base 4 is rotatably arranged on the processing table 2. A mounting hole 41 for placing a bearing is formed in the mounting base 4, and the mounting hole 41 extends through both the upper and lower surfaces of the mounting base 4. It should be noted that the thickness of the mounting base 4 is less than or equal to the length of the bearing, so that when the bearing is placed in the mounting hole 41, both the front and back surfaces of the bearing can protrude or be flush with the surface of the mounting base 4. A positioning assembly 5 for fixing the bearing is arranged in the mounting base 4 (refer to Figure 4 ). Correspondingly, an unlocking assembly 6 for unlocking the positioning assembly 5 is also arranged on the base 1, and a flipping assembly 7 for driving the mounting base 4 to rotate is also arranged on the base 1 (refer to Figure 6 ).

[0031] Refer to Figure 1 . In the embodiment of the present application, a loading station 11, a first unloading station 12, a flipping station 13, a second unloading station 14, and an unloading station 15 are arranged on the base 1 along the circumferential direction of the processing table 2. These five stations are evenly arranged. When the driving assembly 3 drives the processing table 2 to rotate, the mounting base 4 and the bearing placed on the mounting base 4 can be driven to rotate through the above five stations in sequence. Optionally, in order to improve the processing efficiency, multiple mounting bases 4 can be arranged on the processing table 2 in the circumferential direction for multi-station processing. Among them, at most five mounting bases 4 can be arranged.

[0032] Among the above stations, the loading station 11 is used to load the bearing into the mounting hole 41. It can adopt manual loading or the existing loading mechanism, such as a pneumatic gripper, a feeding belt, etc. The first unloading station 12 is used to initially install the rubber ring on the bearing. The rubber ring is also installed by the existing unloading mechanism in this part. The rubber ring is mainly clamped by a pneumatic head or a mechanical claw, and then the rubber ring is moved up and down by a cylinder. When the bearing rotates below the unloading mechanism with the mounting base 4, the rubber ring can be placed at the corresponding position on the bearing. The flipping assembly 7 is arranged at the flipping station 13. When the mounting base 4 rotates to the flipping station 13, it can perform a vertical flip, thereby driving the bearing to turn over. Since the lower surfaces of the processing table 2 and the mounting base 4 are in contact with the upper surface of the positioning table 8, when the mounting base 4 completes the flip, even if the original upper surface of the bearing protrudes from the surface of the mounting base 4, the flipped bearing can move upward relative to adjust the position under the contact of the positioning table 8, so that the upper surface of the flipped bearing still protrudes from the surface of the mounting base 4. The second unloading station 14 is the same as the first station, and is also provided with an unloading mechanism for accurately placing the rubber ring on the bearing. The unloading station 15 is used to remove the bearing, thus completing the processing and collection of the bearing once.

[0033] During the entire process of the bearing rotating with the mounting seat 4, the bearing can be fixed in the mounting hole 41 by the positioning assembly 5 to prevent the bearing from slipping out of the mounting hole 41; at the same time, the unlocking assembly 6 is arranged at the loading station 11 and the unloading station 15. When the mounting seat 4 is located at the loading station 11, the unlocking assembly 6 puts the positioning assembly 5 in an unlocked state, which facilitates the placement of the bearing into the mounting hole 41. When the mounting seat 4 enters the unloading station 15, the unlocking assembly 6 unlocks the positioning assembly 5 again, thereby facilitating the removal of the bearing from the mounting hole 41.

[0034] Reference Figure 1 and Figure 2 Specifically, the driving assembly 3 can be composed of a rotating shaft 31, a driving motor 32 and a transmission component 33. The upper end of the rotating shaft 31 is coaxially fixedly connected to the processing table 2, and the lower end extends downward to rotate through the positioning table 8, and the bottom of the rotating shaft can also be rotatably connected to the base 1 through bearings or the like; the driving motor 32 is preferably a stepping motor, which can accurately control the rotation angle and speed of the processing table 2; the transmission component 33 can be a belt drive, a chain drive or a gear 71 drive; at the same time, the rotating shaft 31 and the output end of the motor are transmitted through the transmission component 33, thereby driving the processing table 2 to rotate.

[0035] Reference Figure 3 and Figure 4 In the embodiment of the present application, the positioning assembly 5 includes a positioning rod 51 and a first spring 52. The positioning rod 51 is symmetrically arranged on both sides of the mounting hole 41. A slide groove 42 is provided on the mounting column for the positioning rod 51 to slide toward or away from the mounting hole 41, and the slide groove 42 extends to be connected with the mounting hole 41; two first springs 52 are arranged corresponding to the positioning rod 51, and each spring is arranged at one end of the positioning rod 51 away from the mounting hole 41; when the bearing is placed in the mounting hole 41, the first spring 52 is in a compressed state, so that the end of the mounting column can be driven to press against the side wall of the bearing to position the bearing, so that the bearing can always be stably located in the mounting hole 41 when the turning station 13 turns over with the mounting seat 4.

[0036] The positioning rod 51 can be set as a rectangular rod, and its end facing the mounting hole 41 is preferably set as an arc surface. This semicircular column head can reduce damage to the bearing when it is pressed against the outer wall of the bearing; in other embodiments, the positioning rod 51 can also be set as a cylindrical shape, and its end face can be correspondingly set as a semicircular column head structure. At the same time, when the mounting seat 4 is flipped, if the bearing needs to move a certain distance along the axis of the mounting hole 41, the abutment method of the arc surface also facilitates the movement of the bearing. Furthermore, a limiting block 511 is fixed on the side wall of the positioning rod 51, and a limiting groove for the limiting block 511 to slide is provided on the mounting seat 4. The limiting block 511 slides in the limiting groove to prevent the positioning rod 51 from escaping from the slide groove 42.

[0037] ReferenceFigure 4 and Figure 5 In the embodiment of the present application, a ring edge 81 is circumferentially formed on the upper surface of the positioning table 8. The processing table 2 is located within the ring edge 81, and there is a spacing between the outer side wall of the positioning table 8 and the inner side wall of the ring edge 81. The unlocking assembly 6 includes a plug rod 61, a connecting rod 62, and a second spring 63. The plug rod 61 is slidably disposed in the mounting seat 4, and its sliding direction is perpendicular to the sliding direction of the positioning rod 51. An unlocking hole 512 for the plug rod 61 to pass through is formed on the side wall of the positioning rod 51. A guiding inclined surface is provided on the side of the plug rod 61 facing away from the mounting hole 41. When the plug rod 61 slides towards the positioning rod 51, the guiding inclined surface of the plug rod 61 can abut against the positioning rod 51 and insert into the unlocking hole 512, thereby driving the positioning rod 51 to slide away from the mounting hole 41, that is, the positioning of the bearing can be unlocked.

[0038] Two plug rods 61 are respectively provided corresponding to the two positioning rods 51. Both ends of the connecting rod 62 are respectively connected to the ends of the two plug rods 61 away from the positioning rod 51. A groove for accommodating the connecting rod 62 is formed on the outer side wall of the mounting seat 4 facing away from the central axis of the processing table 2, and the connecting rod 62 can slide towards the central axis of the processing table 2 in the groove. The second spring 63 is disposed in the mounting seat 4, and the second spring 63 abuts against the side wall of the connecting rod 62 facing the mounting hole 41. In the natural state, the second spring 63 can drive the connecting rod 62 to always slide away from the central direction of the processing table 2 and abut against the inner side wall of the ring edge 81. At this time, the end of the plug rod 61 is located outside the unlocking hole 512. The unlocking assembly 6 further includes an unlocking ring block 64. The unlocking ring block 64 is fixed to the inner side wall of the ring edge 81. Both ends of the unlocking ring block 64 respectively extend to the loading station 11 and the unloading station 15, and inclined surfaces are provided at both ends thereof. When the mounting seat 4 rotates to the unloading station 15, the outer side of the connecting rod 62 abuts against the unlocking ring block 64, so as to slide a certain distance towards the central axis of the processing table 2, and drive the plug rod 61 to slide through the unlocking hole 512, thereby driving the positioning rod 51 to slide away from the mounting hole 41, and releasing the positioning of the bearing.

[0039] Referring to Figure 3 and Figure 4 In an alternative embodiment, the mounting seat 4 includes a positioning portion 44, a dismounting portion 45, and a fixing component 46. The positioning portion 44 is rotatably disposed on the good-through table. The mounting hole 41 and the positioning component 5 are both disposed on the dismounting portion 45. The dismounting portion 45 is detachably mounted on the positioning portion 44 through the fixing component 46. This detachable structure can replace the dismounting portion, thereby changing the size of the mounting hole 41 on the mounting seat 4 to adapt to bearings of different sizes, and improving the applicability of the assembly device.

[0040] Specifically, the fixing assembly 46 includes a plug-in plate 461 and a fixing bolt 462. The plug-in plate 461 is fixedly arranged on the end face of the disassembly part 45. The positioning part 44 is provided with a plug-in slot 441 for the plug-in plate 461 to be plugged in on the side away from the central axis of the processing table 2. The disassembly part 45 is provided with a threaded hole for the fixing bolt 462 to be threadedly connected. The plug-in plate 461 is provided with an opening for the fixing bolt 462 to pass through. When the plug-in plate 461 is inserted into the plug-in slot 441, the opening is aligned with the threaded hole. The disassembly part 45 and the positioning part 44 are fixedly connected by inserting the plug-in plate 461 into the plug-in slot 441 and then passing the fixing bolt 462 through the opening and threading it with the threaded hole. Here, the fixing bolt 462 can be provided in a double-sided manner, or the fixing bolt 462 can be replaced with a buckle structure, so as to conveniently and quickly realize the connection and disassembly of the disassembly part 45 and the positioning part 44.

[0041] Reference Figure 5 In an optional embodiment, an annular guide rail 82 is provided between the positioning table 8 and the processing table 2. The annular guide rail 82 can be fixed on the upper surface of the positioning table 8 or on the lower surface of the processing table 2. Correspondingly, a guide groove for the annular guide rail 82 to rotate is provided on the lower surface of the processing table 2 or the upper surface of the positioning table 8. The cooperation between the annular guide rail 82 and the guide groove can make the processing table 2 rotate more smoothly and reduce shaking.

[0042] Reference Figure 5 and Figure 6 A control shaft 43 is fixed on the side wall of the mounting seat 4 facing the central axis of the processing table 2, that is, the positioning shaft is fixed on the positioning part 44, and the control shaft 43 is rotatably arranged in the processing table 2. The flip assembly 7 includes a gear 71 coaxially sleeved on the control shaft 43, and a tooth block 72 arranged on the positioning table 8. The tooth block 72 is arranged in an arc block, and the upper surface of the tooth block 72 is provided with teeth. The tooth block 72 is arranged at the flip station 13. When the mounting seat 4 passes through the flip station 13, the gear 71 is meshed with the tooth block 72 and drives the mounting seat 4 to flip up and down. The positioning table 8 is provided with a clearance space 83 for the mounting seat 4 to rotate at the flip station 13. When the gear 71 passes the position of the rack, the flipped mounting seat 4 moves to the upper surface of the positioning table 8 and continues to abut against the upper surface of the positioning table 8. Preferably, in order to ensure the stability of the mounting seat 4 after flipping, when the mounting seat 4 is flipped, part of the lower surface of the mounting seat 4 close to the second material discharge station 14 has abutted against the upper surface of the positioning platform 8, thereby limiting the mounting seat 4 from flipping excessively.

[0043] Reference Figure 1 and Figure 5, in the embodiment of the present application, the positioning table 8 is provided with a discharge hole 84 at the blanking station 15, and a material receiving frame 18 is arranged below the discharge hole 84. When the mounting seat 4 rotates with the processing table 2 and moves to the blanking station 15, the mounting hole 41 formed on the mounting seat 4 is exactly located above the discharge hole 84, that is, at this time, the bearing moves above the discharge hole 84; since when the mounting seat 4 rotates into the blanking station 15, under the action of the unlocking ring piece, the positioning rod 51 can be driven to slide through the insertion rod 61 to unlock the bearing, so that at this time, the bearing can fall downward under the action of gravity into the discharge hole 84. The material receiving frame 18 can be arranged on the base 1, and the material receiving frame 18 is located below the discharge hole 84, and the bearing can fall into the material receiving frame 18 along the discharge hole 84.

[0044] Preferably, in order to facilitate the feeding and discharging of the bearing, the sizes of the mounting hole 41 and the discharge hole 84 are slightly larger than the outer diameter of the bearing, ensuring that the bearing can be smoothly placed into the mounting hole 41 and can smoothly fall from the discharge port.

[0045] Referring to Figure 1 and Figure 7 , in an alternative embodiment, a first pressing station 16 is arranged between the first feeding station 12 and the turning station 13, and a second pressing station 17 is arranged between the second feeding station 14 and the blanking station 15. Pressing assemblies 9 for pressing the rubber ring against the bearing are arranged at both the first pressing station 16 and the second pressing station 17. The pressing assembly 9 can make the rubber ring better fit the bearing and improve the installation effect of the rubber ring.

[0046] Specifically, the pressing assembly 9 includes a bracket 91, a mounting shaft 92 slidably arranged up and down on the bracket 91, and a pressing roller 93 rotatably arranged outside the mounting shaft 92. The lower end of the bracket 91 is fixed to the base 1 by means of bolts or the like, and its upper end extends upward outside the processing table 2; the length direction of the mounting shaft 92 is perpendicular to the axis direction of the processing table 2, and it extends above the processing table 2 toward the central axis direction of the processing table 2. The up and down sliding mode of the mounting shaft 92 can be controlled by a screw rod and a handle. Specifically, a slider can be slid up and down on the bracket 91, and the mounting shaft 92 is fixed to the slider. The screw rod threadedly passes through the slider along the vertical direction, and the handle is connected to the upper end of the screw rod. Thus, by rotating the handle, the height of the slider can be adjusted up and down by the screw rod, that is, the height of the mounting shaft 92 and the pressing roller 93 can be adjusted, so that when the bearing rotates with the mounting seat 4 and passes below the pressing roller 93, the pressing roller 93 can press the rubber ring on the bearing.

[0047] The implementation principle of a bearing element sealing and assembling device in an embodiment of the present application is as follows: During assembly, first, the bearing is placed in the mounting hole 41 of the mounting seat 4 at the loading station 11 through the loading mechanism. Then, as the processing table 2 rotates, the mounting seat 4 and the bearing rotate to the first feeding station 12, and the sealing rubber ring is preliminarily installed on the upper surface of the bearing through the feeding mechanism. When the mounting seat 4 rotates past the first pressing station 16, the rubber ring is pressed onto the bearing. Then, the processing table 2 rotates to drive the mounting seat 4 and the bearing to move to the flipping station 13, and a primary flipping of the mounting seat 4 and the bearing is completed under the cooperation of the gear 71 and the tooth block 72. Next, as the processing table 2 rotates to the second feeding station 14, a sealing rubber ring is placed on the other side of the bearing. When moving again, the rubber ring is pressed at the second pressing station 17. Finally, the mounting seat 4 moves to the unloading station 15, and in cooperation with the unlocking ring block 64 and the unlocking and positioning assembly 5 provided at the unloading station 15, the bearing automatically drops from the mounting hole 41 and falls into the bearing frame 18 after passing through the unloading opening.

[0048] The above are all the preferred embodiments of the present application. Without restricting the protection scope of the present application based on this, therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
