Description

Technical Field

[0001] This invention relates to the field of robot bearing manufacturing technology, specifically to a polishing device and method for manufacturing robot bearings. Background Technology

[0002] As a key component of robot joints, locomotion mechanisms, and other core parts, the surface quality of robot bearings directly determines the robot's motion accuracy, operational stability, wear resistance, and service life.

[0003] Currently, existing robotic bearing polishing devices suffer from poor adaptability, mostly only capable of polishing bearings of a single specification. When polishing bearings of different specifications requires changing the corresponding polishing equipment or frequently adjusting the equipment structure, resulting in cumbersome operation and high equipment investment costs. Furthermore, some polishing devices lack precise contact force control and timing control, leading to uneven contact force, inconsistent polishing depth, or over-polishing of some bearings while under-polishing of others. This not only affects the surface quality of the bearings but also increases the scrap rate and reduces production efficiency. Therefore, there is an urgent need for a robotic bearing polishing device that can solve the above-mentioned technical problems. Summary of the Invention

The grinding area at the side end of the grinding component corresponds to the middle area of ​​the bearing shaft. Symmetrical through-holes are provided on both sides of the bearing shaft. A conveyor belt is provided on one side of the through-hole and located inside the bearing shaft. The bottom of the conveyor belt is connected to the bottom inside the bearing shaft. The conveyor belt is generally wider at the top and narrower at the bottom. Several receiving members are evenly distributed on the conveyor belt.

A pin is provided at the top side end of the conveyor belt, and the end of the pin is connected to the drive end of the conveyor belt.

[0009] Preferably, each of the conveyor belts is provided with a linkage shaft above it. The end of the linkage shaft is rotatably connected to a linkage frame at the top side of the inner bearing shaft. A conveyor belt is sleeved on the outer side of the linkage shaft, and the other end of the conveyor belt is sleeved on the outer side of the pin shaft. Each linkage shaft is provided with a drive bevel gear, and the side ends of two drive bevel gears mesh. A rotating shaft is rotatably connected to the top of the bearing shaft.

[0010] Preferably, the cooperating component includes a robotic arm disposed on the side of the worktable, the output end of the robotic arm is provided with a bracket, the bracket is provided with an adjustable trigger, and each trigger is located on the side of an abutment portion.

[0011] Preferably, the method of using the polishing apparatus for manufacturing robot bearings includes the following steps:

[0012] S1: The staff first places bearings of the same specifications on a bearing shaft, so that the bottom of the bearing is on the two receiving parts. The position of the grinding part is adjusted according to the bearing specifications. Then, the threaded rod is driven by rotating the knob, which drives the control frame to slide along the direction of the reference frame under the action of the limit rod, so that the side of the bearing is precisely in contact with the grinding part. During the contact process, the sliding frame slides and adjusts its position in the moving frame through the reaction force. Then, under the action of the balance bar, the angle of the second force rod and the first force rod is adjusted. At the same time, the curved spring sheet keeps the contact part facing the grinding part, so that each bearing is subjected to equal force.

[0013] S2: Control the drive assembly to work, drive the drive shaft to rotate, and under the action of the drive crank and linkage rod, drive the drive table to move back and forth along the worktable, thereby driving each type of bearing to roll back and forth on one side of the grinding workpiece, so that the side ends of bearings of different specifications can be polished by the grinding workpiece under the action of equal contact force.

[0014] S3: During each reciprocating movement, the contact part and the triggering element work together to drive the pressing element downwards along the drive sleeve, compressing the return spring. During this downward movement, the engagement of the embedded part and the V-shaped groove drives the drive roller to rotate within the drive sleeve. After the contact part and the triggering element disengage, the return spring resets, causing the drive roller to continue rotating. This, in turn, drives the control bevel gear and the drive bevel gear to rotate, thereby causing the two linkage shafts to rotate in opposite directions. This, in turn, through the conveyor belt and the pin, causes the two conveyor belts to drive in opposite directions, causing the bearing-supporting receiving part to move downwards a certain distance until it reaches the bottom of the bearing shaft. At this point, the receiving part moves into the bearing shaft according to the action of the conveyor belt. The device detaches the bearing from the grinding surface, allowing the polished bearing to fall to the bottom of the contact part, thus separating it from the grinding part. During each reciprocating movement, the robotic arm and clamps sequentially feed materials from above the bearing shaft, enabling simultaneous polishing of bearings of different specifications and types. It also allows for independent polishing of bearings of the same specifications without interference, ensuring consistent polishing efficiency for all bearings. After polishing, the bearing detaches from the grinding part, effectively preventing over-polishing. The robotic arm and support allow for flexible adjustment of the trigger position, increasing the ease of use.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In this invention, the device can adapt to the polishing operation of robot bearings of different specifications by flexibly adjusting the position of the polishing part and cooperating with the precise contact control of the bearing component. There is no need to configure polishing equipment separately for bearings of different specifications, which reduces the equipment investment cost and improves the versatility and practicality of the equipment.

[0017] In this invention, the drive component drives the bearing component to move back and forth, ensuring that the side ends of bearings of different specifications and the grinding parts always maintain the same contact force. This avoids problems such as uneven polishing depth and surface roughness caused by uneven contact force, improves the flatness and smoothness of the bearing surface, and thus ensures the robot's motion accuracy and operational stability, and extends the service life of the bearings and the core components of the robot.

[0018] In this invention, by having the timing control component and the cooperating component work together, it is possible to achieve independent polishing of individual bearings, ensuring that the polishing efficiency of all bearings is consistent and avoiding the situation where some bearings are not polished enough or some bearings are over-polished. Furthermore, it is possible to automatically remove the bearing from the polishing part after polishing, which can effectively reduce bearing surface wear, reduce scrap rate, and improve production efficiency.

[0019] In this invention, workers only need to classify and place the bearings and adjust the position of the polishing parts. The subsequent polishing process can be completed automatically through the collaboration of various components, without the need for full-time human supervision and intervention. This simplifies the operation process, reduces human error, and lowers the labor intensity of workers. Attached Figure Description

The bracket 102 is provided with an adjustable trigger 103. Each trigger 103 is located on the side of an abutment portion 90.

[0039] In this embodiment, as Figures 1 to 10 As shown, a method of using a polishing apparatus for manufacturing robot bearings includes the following steps:

[0040] S1: The staff first places bearings of the same specifications on a bearing shaft 71, so that the bottom of the bearing is on the two receiving parts 75. The position of the grinding part 2 is adjusted according to the bearing specifications. Then, the threaded rod 55 is driven by rotating the knob 56, which drives the control frame 52 to slide along the direction of the reference frame 51 under the action of the limit rod 53, so that the side end of the bearing is precisely in contact with the grinding part 2. During the contact process, the sliding frame 58 slides and adjusts its position in the moving frame 59 through the reaction force. Then, the angle of the second force rod 65 and the first force rod 60 is adjusted under the action of the balance rod 67. At the same time, the curved spring sheet makes the contact part 61 able to maintain the angle facing the grinding part 2, so that each bearing is subjected to equal force.

[0041] S2: Control the drive assembly 4 to work, drive the drive shaft 41 to rotate, and under the action of the drive crank 43 and the linkage rod 44, drive the drive table 45 to move back and forth along the worktable 1, and then drive each type of bearing to roll back and forth on one side of the grinding part 2, so that the side ends of bearings of different specifications can be polished by the grinding part 2 under the action of the same contact force.

[0042] S3: During each reciprocating movement, the pressing part 86 moves downward along the drive sleeve 85 through the cooperation of the contact part 90 and the trigger 103, compressing the return spring 87. During the downward movement, the drive roller 83 rotates within the drive sleeve 85 through the cooperation of the embedded part 89 and the V-shaped groove 84. After the contact part 90 and the trigger 103 disengage, the return spring 87 resets, causing the drive roller 83 to continue rotating. This, in turn, drives the control bevel gear 82 and the drive bevel gear 80 to rotate, thereby causing the two linkage shafts 77 to rotate in opposite directions. This, in turn, through the conveyor belt 79 and the pin 76, causes the two conveyor belts 74 to drive in opposite directions, causing the bearing-supporting member 75 to move downward a certain distance until it reaches the bottom of the bearing shaft 71. At this point, the bearing-supporting member 75 moves downward according to the conveyor belt. The function of component 74 is to move into the bearing shaft 71, causing it to detach from the bearing, and then allowing the polished bearing to fall to the bottom of the contact component 61, detaching it from the grinding component 2. Simultaneously, during each reciprocating movement, the robotic arm 101 and clamp 72 can sequentially feed materials from above the bearing shaft 71, enabling simultaneous polishing of bearings of different specifications and types. It also allows for independent polishing of bearings of the same specifications without mutual obstruction, ensuring consistent polishing efficiency for all bearings. After polishing, the bearing detaches from the grinding component 2, effectively preventing over-polishing. The robotic arm 101 and bracket 102 allow for flexible adjustment of the trigger component 103, increasing the ease of use of the device.

8. A method of using a polishing apparatus for manufacturing robot bearings, comprising using a polishing apparatus for manufacturing robot bearings as described in any one of claims 1-7, characterized in that, Includes the following steps: S1: The staff first placed bearings of the same specifications on a bearing shaft (71) so that the bottom of the bearing was on two receiving parts (75). The position of the grinding part (2) was adjusted according to the bearing specifications. Then, the threaded rod (55) was rotated by the rotary knob (56), which caused the control frame (52) to slide along the direction of the reference frame (51) under the action of the limit rod (53), so that the side end of the bearing was precisely in contact with the grinding part (2). During the contact process, the sliding frame (58) was adjusted in the moving frame (59) by the reaction force. Then, the angle of the second force rod (65) and the first force rod (60) was adjusted under the action of the balance rod (67). At the same time, the contact part (61) was kept at the angle of the grinding part (2) by the curved spring sheet, so that each bearing was subjected to equal force. S2: Control the drive assembly (4) to work, drive the drive shaft (41) to rotate, and under the action of the drive crank (43) and linkage rod (44), drive the drive table (45) to move back and forth along the worktable (1), and then drive each type of bearing to roll back and forth on one side of the grinding part (2), so that the side ends of bearings of different specifications can be polished by the grinding part (2) under the action of the same contact force; S3: During each reciprocating movement, the pressing part (86) moves down along the drive sleeve (85) through the cooperation of the contact part (90) and the trigger (103), compressing the return spring (87). During the downward movement, the drive roller (83) rotates inside the drive sleeve (85) through the cooperation of the insert (89) and the V-shaped groove (84). After the contact part (90) and the trigger (103) disengage, the return spring (87) resets, causing the drive roller (83) to continue rotating. This drives the control bevel gear (82) and the drive bevel gear (80) to rotate, thereby causing the two linkage shafts (77) to rotate in opposite directions. This, in turn, causes the two conveyor belts (74) to drive in opposite directions through the conveyor belt (79) and the pin (76), causing the bearing-supporting support part (75) to move down a certain distance until it reaches the bottom of the bearing shaft (71). The receiving part (75) moves to the inside of the bearing shaft (71) according to the action of the conveyor belt (74), so that it is separated from the bearing, and then the polished bearing falls to the bottom of the contact part (61) and is separated from the contact of the grinding part (2). At the same time, during each reciprocating movement, the mechanical arm (101) and the clamp (72) can be controlled to feed materials from the top of the bearing shaft (71) in sequence, so that bearings of different specifications and types can be polished synchronously. Bearings of the same specifications can be polished independently during the polishing process without hindering each other, and the polishing efficiency of all bearings is consistent. After the polishing operation is completed, it is separated from the grinding part (2), effectively avoiding over-polishing. The position of the trigger part (103) can be flexibly adjusted by the mechanical arm (101) and the bracket (102), increasing the convenience of using this device.
