Description

Technical Field

[0001] This utility model relates to the field of planetary wheel polishing technology, and in particular to a polishing machine for planetary wheel processing. Background Technology

[0002] A planetary gear is a crucial component in mechanical transmission. It typically consists of a gear body and gear teeth, and is commonly used in planetary gear transmission systems. In a planetary gear mechanism, the planetary gear revolves around the central gear (sun gear) while also rotating on its own axis. Its revolution is due to its meshing relationship with the central gear and other gears, and it rotates around the central gear under the drive of external power. Its rotation is caused by the forces acting on it and the constraints it faces with other components during its revolution.

[0003] Planetary wheel polishing is a common metal surface treatment process that mainly uses a planetary wheel device to polish workpieces. During planetary wheel polishing, multiple workpieces are fixed on the planetary wheel, which revolves around a central axis while also rotating on its own axis. This combined motion allows the workpieces to come into uniform contact with the polishing wheel or polishing medium, thereby achieving comprehensive and meticulous polishing.

[0004] However, the polishing of some planetary wheels is usually done by hand polishing and ordinary mechanical polishing. However, the efficiency and consistency of both methods are difficult to meet the needs of modern industry. Although automated polishing equipment improves efficiency, its complex structure and high maintenance costs limit its widespread application. Moreover, existing equipment has poor adaptability to the shape and size of planetary wheels, making it difficult to meet diverse processing needs. Therefore, in order to address the above shortcomings, a polishing machine for planetary wheel processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a polishing machine for planetary gear processing, which aims to improve the problem that the polishing of planetary gears in the prior art cannot effectively improve efficiency and has poor adaptability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a polishing machine for planetary wheel processing, comprising a base, a slide rail fixedly connected to the top of the base, a stand fixedly connected to the top of the base, a rotating clamping mechanism slidably connected to the top of the slide rail, and a downward polishing mechanism provided on the top of the stand.

[0007] The rotating clamping mechanism includes a rotating component, the bottom of which is slidably connected to the top of the slide rail. A bottom frame is fixedly connected to the top of the rotating component. A driving component is provided on the rear side of the bottom frame. A trapezoidal block is fixedly connected to the front side of the driving component. Slide grooves are provided on both the left and right sides of the trapezoidal block. Two slides are slidably connected inside the trapezoidal block. Inclined columns are fixedly connected to the far sides of the two slides. Slide plates are fixedly connected to the far sides of the two inclined columns. Clamping plates are fixedly connected to the top of the two slide plates. Rubber plates are fixedly connected to the near sides of the two clamping plates. Two sliding grooves are provided on the top of the bottom frame.

[0008] Through the above technical solution: when the drive component works, it drives the trapezoidal block to move, and the slide slides along the slide groove inside the trapezoidal block. The slide pushes the slide plate through the inclined column, and the slide plate drives the clamping plate to move along the sliding groove at the top of the bottom frame, so that the two clamping plates can move closer or further apart. The rubber plate on the clamping plate can stably and gently clamp the planetary wheel, and complete the fixation of the planetary wheel. In conjunction with the downward sweeping mechanism, the sweeping and polishing processing of the planetary wheel can be realized.

[0009] As a further description of the above technical solution:

[0010] The rotating assembly includes an outer frame, and a motor is installed inside the outer frame. The output end of the motor is fixedly connected to a rotating shaft.

[0011] Through the above technical solution: when the motor starts, the electrical energy of the motor is converted into mechanical energy, which drives the rotating shaft to rotate, thereby enabling the entire rotating assembly to rotate, realizing the rotational movement of the rotating clamping mechanism. In conjunction with other components of the rotating clamping mechanism, it can better position and fix the planetary wheel at multiple angles, providing conditions for the subsequent downward sweeping and polishing mechanism to perform comprehensive and efficient sweeping and polishing processing on the planetary wheel.

[0012] As a further description of the above technical solution:

[0013] The drive assembly includes a cylinder, the rear side of which is installed inside the bottom frame, and a push rod is fixedly connected to the drive end of the cylinder.

[0014] Through the above technical solution: when cylinder one is working, the air pressure inside cylinder one changes, which pushes push rod one to move forward. The movement of push rod one drives the trapezoidal block on the front side to move. The slide carriage slides along the slide groove inside the trapezoidal block. The slide carriage pushes the slide plate through the inclined column.

[0015] As a further description of the above technical solution:

[0016] The downward sweeping mechanism includes a second cylinder. A second push rod is fixedly connected to the drive end of the second cylinder. A placement frame is fixedly connected to the bottom of the second push rod. Two guide frames are fixedly connected to the top of the placement frame. A second motor is installed inside the placement frame. A rotating shaft is fixedly connected to the output end of the second motor. A rotating disk is fixedly connected to the bottom of the rotating shaft. Sliding rings are slidably connected to both the front and rear sides of the rotating disk. Sliding rods are fixedly connected inside each of the two sliding rings. Springs are sleeved on the outside of each of the two sliding rods. Pull plates are fixedly connected to the far sides of each of the two sliding rods. Locking plates are fixedly connected to the near sides of each of the two sliding rods. Two locking frames are slidably connected inside the rotating disk. Sliding grooves are opened inside each of the two locking frames. Locking slots are opened on the top of each of the two locking frames. A docking plate is fixedly connected to the bottom of each of the two locking frames. A polishing wheel is fixedly connected to the bottom of the docking plate.

[0017] Through the above technical solution: the second motor starts, driving the rotating shaft and rotating disk to rotate. When the rotating disk rotates, the polishing wheel rotates synchronously with the rotating disk to perform polishing on the planetary wheel that has been clamped and fixed below.

[0018] As a further description of the above technical solution:

[0019] The outer side of the carriage is slidably connected to the inside of the slide groove, and the outer side of the slide plate is slidably connected to the inside of the slide groove.

[0020] The above technical solution provides a sliding track for the carriage and a sliding groove for the skateboard.

[0021] As a further description of the above technical solution:

[0022] The bottom of the base frame is rotatably connected to the top of the outer frame, and the bottom of the clamping plate is slidably connected to the top of the base frame.

[0023] Through the above technical solution, the rotation of the bottom frame can drive the rotation of the planetary wheel, thereby achieving the polishing of the planetary wheel.

[0024] As a further description of the above technical solution:

[0025] The card plate is slidably connected to the inside of the sliding groove, and the card plate is rotatably connected to the inside of the card groove.

[0026] Through the above technical solution, the card plate can both slide in the sliding groove and rotate in the card slot, thereby realizing the connection and cooperation effect between the card plate and the sliding groove and the card slot under different movement modes.

[0027] As a further description of the above technical solution:

[0028] One end of the spring is fixedly connected to the outside of the sliding ring, and the other end of the spring is fixedly connected to the inside of the rotating disk.

[0029] The above technical solution allows for the release and locking of the clamping plate by utilizing the elastic force of the spring, thereby enabling the quick installation and removal of the polishing wheel.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the slide rail drives the outer frame to move, and the motor one precisely controls the rotation angle and speed of the bottom frame, which can polish and grind different positions of the planetary wheel. At the same time, the motor two in the downward sweeping mechanism drives the polishing wheel to rotate at high speed, ensuring the consistency of the planetary wheel surface treatment. In addition, the cooperation between the slide and the slide groove, as well as the guiding effect of the slide groove on the slide plate, ensures the stability of the clamping action, keeps the planetary wheel fixed during the processing, and further improves the processing efficiency and consistency.

[0032] 2. In this invention, when the polishing wheel needs to be disassembled, rotating the pull plate drives the sliding rod to rotate, causing the retaining plate to rotate from the retaining slot to the sliding slot, and then slide out with the help of the spring force, thus removing the polishing wheel. Installation is performed by reversing the operation. This design not only saves time when replacing the polishing wheel but also reduces the risk of damage to the equipment caused by frequent disassembly, improving the overall efficiency of the equipment.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a planetary wheel polishing machine, including a base 1, which serves as the basic support structure for the polishing machine. A slide rail 2 is fixedly connected to the top of the base 1, and a stand 3 is fixedly connected to the top of the base 1. A rotating clamping mechanism 4 is slidably connected to the top of the slide rail 2, and a downward polishing mechanism 5 is provided on the top of the stand 3. The rotating clamping mechanism 4 includes a rotating component 41, which includes an outer frame 4101. A motor 4102 is installed inside the outer frame 4101. The motor 4102 provides power for the rotation of the bottom frame 42, and can precisely control the rotation angle and speed of the bottom frame 42 to meet different processing requirements. The bottom of the bottom frame 42 is rotatably connected to the top of the outer frame 4101. A rotating shaft 4103 is fixedly connected to the output end of the motor 4102. The bottom of the rotating component 41 is slidably connected to the top of the slide rail 2, and the top of the rotating component 41 is fixedly connected to the bottom frame 42. A drive component 43 is provided on the rear side of the bottom frame 42.

[0043] The drive assembly 43 includes a cylinder 4301, the rear of which is mounted inside the base frame 42. A push rod 4302 is fixedly connected to the drive end of the cylinder 4301. A trapezoidal block 44 is fixedly connected to the front of the drive assembly 43. The push rod 4302 transmits the linear motion of the cylinder 4301 to the trapezoidal block 44, pushing it forward. Slide grooves 45 are provided on both the left and right sides of the trapezoidal block 44. Two slides 46 are slidably connected inside the trapezoidal block 44, and the slides 46 are slidably connected to the inside of the slide grooves 45. The slide grooves 45 cooperate with the slides 46 to effectively prevent the slides 46 from shifting or shaking during sliding, ensuring the accuracy and stability of the slides 46's movement. Inclined columns 47 are fixedly connected to the opposite sides of the two slides 46. As the trapezoidal block 44 moves, the inclined columns... 47 undergoes lateral displacement under the action of its inclined surface, thereby driving the slide plate 48 to move. Slide plates 48 are fixedly connected to the far side of the two inclined columns 47. Clamping plates 49 are fixedly connected to the top of the two slide plates 48. The opening and closing of clamping plates 49 is achieved by the movement of slide plates 48. The bottom of clamping plates 49 is slidably connected to the top of the bottom frame 42. Rubber plates 410 are fixedly connected to the near side of the two clamping plates 49. Rubber plates 410 increase the friction between the rubber plates 410 and the planetary wheel, preventing the planetary wheel from sliding during clamping and avoiding damage to the surface of the planetary wheel. Two sliding grooves 411 are opened on the top of the bottom frame 42. The outside of the slide plate 48 is slidably connected to the inside of the sliding groove 411. The sliding groove 411 provides guidance for the sliding of the slide plate 48, ensuring the stability and accuracy of the slide plate 48 during movement.

[0044] Specifically, motor 4102 can precisely control the rotation angle and speed of the base frame 42 to meet different processing requirements. The bottom of the rotating component 41 can slide along the slide rail 2, and the top is connected to the base frame 42. In the drive component 43 on the rear side of the base frame 42, cylinder 4301 pushes push rod 4302 to move trapezoidal block 44 forward. The sliding grooves 45 on both sides of the trapezoidal block 44 cooperate with the internal slide 46 to ensure that the slide 46 does not deviate or shake when sliding. The slide 46 drives the slide plate 48 to move through the inclined column 47. The slide plate 48 slides in the sliding groove 411 at the top of the base frame 42 to realize the opening and closing of the top clamping plate 49. The rubber plate 410 on the inner side of the clamping plate 49 increases the friction with the planetary wheel to avoid planetary wheel slippage and surface damage. The entire polishing machine achieves stable clamping and multi-angle rotation of the planetary wheel through the coordinated movement of various components, providing good conditions for subsequent polishing processing.

[0045] Reference Figure 2 , Figure 5 and Figure 6The downward sweeping mechanism 5 includes a second cylinder 51. The drive end of the second cylinder 51 is fixedly connected to a second push rod 52. The second cylinder 51 can precisely control the lifting stroke of the second push rod 52. The bottom of the second push rod 52 is fixedly connected to a placement frame 53. The top of the placement frame 53 is fixedly connected to two guide frames 54. The guide frames 54 provide guidance for the lifting of the placement frame 53 and prevent the placement frame 53 from shaking or shifting during the lifting process. The placement frame 53 is equipped with a second motor 55. The second motor 55 provides power for the rotation of the rotating shaft 56 and the rotating disk 57. The speed can be adjusted according to the processing requirements. The output end of the second motor 55 is fixedly connected to the rotating shaft 56. The bottom of the rotating shaft 56 is fixedly connected to the rotating disk 57. Sliding rings 58 are slidably connected to both the front and rear sides of the rotating disk 57. Sliding rods 59 are fixedly connected inside the two sliding rings 58. The sliding rods 59 move synchronously as the sliding rings 58 slide in the sliding groove 45. Springs 510 are sleeved on the outside of the two sliding rods 59.

[0046] One end of the spring 510 is fixedly connected to the outside of the sliding ring 58, and the other end of the spring 510 is fixedly connected to the inside of the rotating disk 57. During the locking and unlocking process of the locking plate 512, it provides the necessary elastic force to ensure the stable operation of the locking plate 512. Pull plates 511 are fixedly connected to the far sides of the two sliding rods 59. The pull plates 511 facilitate manual rotation by the operator. Rotating the pull plates 511 drives the sliding rods 59 to rotate, thus operating the locking plate 512. Lock plates 512 are fixedly connected to the near sides of the two sliding rods 59. Two locking frames 513 are slidably connected inside the rotating disk 57. Through the cooperation of the locking plates 512 with the locking slots 515 and sliding grooves 514, connection and separation with the rotating disk 57 are achieved, facilitating the installation and removal of the polishing wheel 517. The two locking frames 51... Each of the two frames 513 has a sliding groove 514 inside. The outer side of the card plate 512 is slidably connected to the inside of the sliding groove 514. The top of each of the two frames 513 has a slot 515. The slot 515 provides support for the rotation of the card plate 512 and ensures the stability of the card plate 512 in the locked state. The outer side of the card plate 512 is rotatably connected to the inside of the slot 515. The bottom of the two frames 513 is fixedly connected to a docking plate 516. The docking plate 516 is connected to the rotating disk 57 through the connection of the frames 513 and the rotating disk 57, so that the polishing wheel 517 is fixedly connected to the rotating disk 57, and the polishing wheel 517 rotates together with the rotating disk 57. The bottom of the docking plate 516 is fixedly connected to the polishing wheel 517. During the rotation, the polishing wheel 517 polishes and grinds the surface of the planetary wheel to improve the surface quality of the planetary wheel.

[0047] Specifically, motor 55 provides rotational power to the rotating shaft 56 and the rotating disk 57, and the speed can be adjusted as needed. The operator can rotate the pull plate 511 to drive the sliding rod 59, and then operate the clamping plate 512. The clamping plate 512 connects and separates from the rotating disk 57 through the cooperation of the sliding groove 514 in the clamping frame 513 and the top clamping groove 515, which facilitates the installation and removal of the polishing wheel 517. The clamping plate 512 rotates in the clamping groove 515, which provides support for it. The docking plate 516 connects the clamping frame 513 and the rotating disk 57, so that the polishing wheel 517 rotates with the rotating disk 57 to polish and grind the surface of the planetary wheel, thereby improving the surface quality of the planetary wheel.

[0048] Working principle: When using this planetary wheel polishing machine, first place the planetary wheel on top of the base frame 42. Then, start the cylinder 4301 to drive the push rod 4302 to move, which in turn pushes the trapezoidal block 44 to move. As the trapezoidal block 44 moves, the inclined surface design between the inclined column 47 and the trapezoidal block 44 causes the inclined column 47 to move under the displacement of the trapezoidal block 44. At this time, the slide 46 slides inside the slide groove 45, which in turn drives the slide plate 48 to move. This causes the two clamping plates 49 to move closer together, and then, with the help of the rubber plate 41, they can move closer together. The first step is to clamp and fix the planetary wheel. Then, the second cylinder 51 is activated to drive the second push rod 52 to move downward, which in turn causes the placement frame 53 to move. At this time, the polishing wheel 517 will move downward and come into contact with the clamped planetary wheel. Then, the second motor 55 is activated to drive the rotating shaft 56 and the rotating disk 57 to rotate, which in turn drives the polishing wheel 517 to rotate, thus realizing the polishing operation. Then, the outer frame 4101 is moved by the slide rail 2, which in turn moves the clamped planetary wheel, thus realizing polishing and grinding at different positions.

[0049] When the polishing wheel 517 needs to be disassembled, the sliding rod 59 is rotated by rotating the pull plate 511, which in turn rotates the clamping plate 512 inside the clamping groove 515. At this time, the clamping plate 512 is aligned with the inside of the sliding groove 514. Then, with the help of the spring force of the spring 510, the clamping plate 512 slides out from the inside of the sliding groove 514. At this time, the clamping plate 512 can be removed from the inside of the docking plate 516, thereby realizing the disassembly of the polishing wheel 517. When the polishing wheel 517 needs to be installed, simply reverse the above steps to make the clamping plate 512 slide back into the inside of the clamping groove 515, and lock the clamping frame 513 with the help of the spring force of the spring 510.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
