Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and more specifically, it relates to a chamfering device for a self-lubricating bearing processing lathe. Background Technology

[0002] Self-lubricating bearings are classified into composite material self-lubricating bearings, solid inlaid self-lubricating bearings, bimetallic material self-lubricating bearings, and special material self-lubricating bearings. Different self-lubricating bearings are selected according to different applications and working conditions. During the production process, self-lubricating bearings require the use of a chamfering device to chamfer the inner and outer sides of the bearing.

[0003] Utility model patent application number 202122689124.3 discloses a chamfering device for a self-lubricating bearing machining lathe, including a worktable, an outer chamfering component, and an inner chamfering component. The outer chamfering component and the inner chamfering component cooperate with each other. The upper surface of the worktable is provided with an inwardly recessed movable groove. The inner chamfering component includes a first gear movably installed in the movable groove. The first gear meshes with multiple second gears. The upper surface of the multiple second gears is provided with a fixing rod. Chamfering blocks are fixedly provided on the outer wall of the multiple fixing rods. This device, by setting the cooperating outer chamfering component and inner chamfering component, can effectively chamfer bearings.

[0004] However, in the existing technology, it is not possible to fix multiple self-lubricating bearings that need to be chamfered at one time and chamfer them sequentially. After one self-lubricating bearing is chamfered, the chamfering block that needs to be chamfered needs to be stopped. The chamfered self-lubricating bearing is then removed and another self-lubricating bearing to be chamfered is fixed before the chamfering work of the next self-lubricating bearing can be carried out. The continuous loading and unloading of self-lubricating bearings is inconvenient and time-consuming, reduces the continuity of chamfering work and affects the efficiency of chamfering work. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a chamfering device for a self-lubricating bearing machining lathe.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A chamfering device for a self-lubricating bearing machining lathe includes a worktable, a frame mounted on the worktable, a motor mounted on the frame, and a grinding head for chamfering the self-lubricating bearing mounted on the output end of the motor. A work plate is movably connected to the worktable, and a fixing part for fixing the self-lubricating bearing is rotatably connected to the work plate.

[0008] Further configured, a first servo motor is mounted on the workbench, a first gear is mounted on the output end of the first servo motor, a support column corresponding to the center of the work plate is rotatably connected to the workbench, a second gear meshing with the first gear is mounted on one end of the support column, a fixed tube is rotatably connected to the work plate and threaded to the other end of the support column, a stop ring is mounted on the fixed tube, a plurality of first stop screw holes are opened on the stop ring and evenly arranged around the fixed tube, a second stop screw hole is opened on the work plate and mates with the first stop screw hole, a stop rod is provided on the work plate and threadedly connected to the second stop screw hole and the first stop screw hole in sequence, and the fixed tube mates with a plurality of fixed parts.

[0009] A further configuration includes a third gear rotatably connected to the fixed tube, a second servo motor mounted on the working disk along the arrangement path of the fixed part, the output end of the second servo motor passing through the working disk and rotatably connected to the working disk, and a transmission gear meshing with the third gear mounted on the output end of the second servo motor.

[0010] The fixing part includes a rotating rod rotatably connected to the working plate, a fourth gear connected to one end of the rotating rod, a fixing plate connected to the other end of the rotating rod, two fixing blocks respectively connected to both sides of the fixing plate, two fastening screws respectively movably connected to the two fixing blocks, and two clamping blocks respectively connected to the two fastening screws. Rubber protective pads are installed on the clamping blocks. The fourth gears of the fixing parts are arranged around the third gear, and the third gear meshes with the fourth gears of the fixing parts.

[0011] Further configured, the fixing block has a threaded hole that is threaded to the corresponding fastening screw.

Detailed Implementation

[0021] Reference Figures 1 to 5 The embodiments of this utility model will be further described below.

[0022] A chamfering device for a self-lubricating bearing machining lathe includes a worktable 100, a frame 200 mounted on the worktable 100, a motor 201 mounted on the frame 200, a grinding head 202 for chamfering the self-lubricating bearing mounted on the output end of the motor 201, a work plate 1 on the worktable 100, a fixing part 2 for fixing the self-lubricating bearing, a plurality of fixing parts 2 are evenly arranged around the work plate 1, the fixing parts 2 correspond to the grinding head 202, a support column 5 corresponding to the center of the work plate 1 is rotatably connected to the worktable 100, a first servo motor 3 is mounted on the worktable 100, a first gear 4 is mounted on the output end of the first servo motor 3, a second gear 6 meshing with the first gear 4 is mounted on one end of the support column 5, and a fixing tube 7 threadedly connected to the other end of the support column 5 is rotatably connected to the work plate 1 via a bearing.

[0023] As needed, the fixed pipe 7, which is threadedly connected to the support column 5, is rotated to adjust the height of the work plate 1 connected to the fixed pipe 7. This aligns the self-lubricating bearing on the work plate 1, which is fixed by the fixed part 2, with the grinding head 202. This allows the motor 201 to drive the grinding head 202 to rotate for grinding and chamfering. The work plate 1 and the fixed pipe 7 are connected by the bearing. After the height of the work plate 1 is adjusted, rotating the work plate 1 allows the first fixed part 2 on the work plate 1 to align with the grinding head 202. This allows the grinding head 202 to start grinding and chamfering from the self-lubricating bearing fixed by the first fixed part 2. The first servo motor 3 works by driving the second gear 6 through the first gear 4, which in turn drives the support column 5 and the fixed pipe 7 to rotate, thus rotating the work plate 1. This achieves the purpose of rotating the several fixed parts 2 on the work plate 1, allowing the grinding head 202 to grind and chamfer the multiple self-lubricating bearings fixed by the several fixed parts 2 in sequence.

[0024] A third gear 11 is rotatably connected to the fixed tube 7 via a bearing. A second servo motor 12 is mounted on the working plate 1, arranged along the path of the fixed part 2. The output end of the second servo motor 12 passes through the working plate 1 and is rotatably connected to the working plate 1. A transmission gear 13 that meshes with the third gear 11 is mounted on the output end of the second servo motor 12. The fixed part 2 includes a rotating rod 21 rotatably connected to the working plate 1, a fourth gear 22 connected to one end of the rotating rod 21, a fixed plate 23 connected to the other end of the rotating rod 21, and two fixed parts respectively connected to both sides of the fixed plate 23. The system includes a fixed block 24, two fastening screws 25 movably connected to the two fixed blocks 24, and two clamping blocks 26 connected to the two fastening screws 25. Rubber protective pads 261 are installed on the clamping blocks 26. The rotating rod 21 is rotatably connected to the working plate 1 through a bearing passing through the working plate 1. The cross-section of the clamping block 26 is circular. The fixed block 24 has threaded holes 14 that are threaded to the corresponding fastening screws 25. The fourth gears 22 of several fixed parts 2 are arranged around the third gear 11, and the third gear 11 meshes with the fourth gears 22 of several fixed parts 2.

[0025] The self-lubricating bearing is placed on the fixing plate 23 of the corresponding fixing part 2, and positioned between the two clamping blocks 26 on the corresponding fixing plate 23. The fastening screws 25 are threaded into the threaded holes 14 on the corresponding fixing blocks 24. By rotating the two fastening screws 25, the clamping blocks 26 on them come into contact with the self-lubricating bearing, thereby fixing the self-lubricating bearing on the fixing plate 23. This achieves the fixing part 2's fixation of the self-lubricating bearing. The rubber protective pads 261 on the clamping blocks 26 prevent direct contact between the clamping blocks 26 and the self-lubricating bearing, thus preventing damage to the bearing surface. Several fixing parts 2 are provided, thereby achieving the fixing of multiple self-lubricating bearings on the working plate 1. The second servo motor 1... The operation of the transmission gear 13 causes the transmission gear 13 to rotate, which in turn drives the third gear 11 on the fixed tube 7 to rotate, and then drives the fourth gear 22 to rotate, so as to drive the rotating rod 21 connected to the fixed plate 23 to rotate. At this time, the self-lubricating bearing fixed on the fixed plate 23 rotates with the fixed plate 23 to facilitate the grinding head 202 to complete the grinding and chamfering work. In conjunction with the operation of the first servo motor 3, the support column 5 is driven to rotate through the meshing of the first gear 4 and the second gear 6, so as to rotate the working plate 1 and several fixed parts 2 on it, so that the next self-lubricating bearing fixed to the adjacent fixed part 2 can rotate to correspond with the grinding head 202 to perform the grinding and chamfering work of the next self-lubricating bearing.

[0026] A stop ring 8 is installed on the fixed tube 7. The stop ring 8 has several first stop screw holes 81 evenly arranged around the fixed tube 7. The working plate 1 has a second stop screw hole 9 that mates with the first stop screw hole 81. The working plate 1 is provided with a stop rod 10 that is threadedly connected to the second stop screw hole 9 and the first stop screw hole 81 in sequence.

[0027] After the first fixing part 2 on the rotating work plate 1 is aligned with the grinding head 202, the work plate 1 is fixed by connecting the stop rod 10 with the second stop screw hole 9 and the corresponding first stop screw hole 81 on the stop ring 8. This prevents the work plate 1 on the fixing tube 7 from rotating arbitrarily when the grinding head 202 is working, which would cause the grinding head 202 to be misaligned with the self-lubricating bearing fixed to the corresponding fixing part 2, thus affecting the grinding and chamfering work.

[0028] The working plate 1 has a through hole 15 for the output end of the second servo motor 12 to pass through. The output end of the second servo motor 12 rotates within the through hole 15, thus realizing the rotational connection between the output end of the second servo motor 12 and the working plate 1.

[0029] A handle 16 is installed on the fixed tube 7 to facilitate rotation of the fixed tube 7. By applying force to the handle 16, it is easier to rotate the fixed tube 7 to adjust the height of the working plate 1.

[0030] In use: Multiple self-lubricating bearings are fixed to the working plate 1 by several fixing parts 2. Specifically, the self-lubricating bearing is placed between two clamping blocks 26 on the fixing plate 23, and the clamping blocks 26 are tightened and fixed to the fixing plate 23 by rotating the fastening screw 25. As needed, the height of the working plate 1 is adjusted by rotating the fixing tube 7 by the handle 6. The working plate 1 is rotated so that one of the fixing parts 2 adjacent to the second servo motor 12 corresponds to the grinding head 202, so that the self-lubricating bearing fixed by this fixing part 2 is the first self-lubricating bearing to be ground and chamfered. The motor 201 drives the grinding head 202 to rotate at high speed to grind and chamfer the self-lubricating bearing. During the grinding process of the grinding head 202, the second servo motor 12 works and drives the third gear 11 on the fixing tube 7 to rotate through the transmission gear 13. This causes the fourth gear 22 of the fixing part 2 to rotate, driving the rotating rod 21 and its fixing plate 23 to rotate. The self-lubricating bearing fixed on the fixing plate 23 rotates with the fixing plate 23, which facilitates the grinding head 202 to complete the grinding and chamfering work of the self-lubricating bearing.

[0031] After the first self-lubricating bearing has been ground and chamfered, the first servo motor 3 drives the support column 5 to rotate through the meshing of the first gear 4 and the second gear 6. This causes the working disc 1 and its several fixed parts 2 to rotate, facilitating the rotation of the next self-lubricating bearing fixed to the adjacent fixed part 2 to correspond with the grinding head 202 for the next self-lubricating bearing to be ground and chamfered. This process continues until all self-lubricating bearings have been ground and chamfered. Ultimately, this allows for the simultaneous fixing of multiple self-lubricating bearings that require chamfering and sequential chamfering. This avoids the need to stop the machine to disassemble and reassemble the self-lubricating bearing after it has been chamfered before the next self-lubricating bearing can be chamfered. This enables the continuous chamfering of multiple self-lubricating bearings, avoiding the inconvenience and time-consuming problems caused by constantly loading and unloading self-lubricating bearings, and improving the continuity and efficiency of the chamfering work.
