Technical Field
[0001] This utility model relates to the field of gear shaft processing, and more specifically, to a gear shaft polishing device. Background Technology
[0002] Gear shaft polishing is a comprehensive process that combines material properties, machining precision, and surface treatment technology. It aims to improve surface finish, reduce friction, enhance corrosion resistance, and improve appearance. Through reasonable process selection and strict process control, gear shaft polishing can significantly improve its performance and lifespan without sacrificing functionality.
[0003] A search revealed that Chinese Patent Publication No. CN222134571U discloses "a dust-free polishing device for gear shafts; including a lifting component, a clamping component, an adjusting component, a polishing component, a shielding component, and a dust removal component; compared with the prior art where operators approach the polishing wheel for polishing, which poses certain risks and the generated dust can affect the operator's health, this utility model, through the cooperation of the lifting component, clamping component, adjusting component, and polishing component, can perform automated polishing of gear shafts without requiring manual operation, thus increasing safety. Furthermore, the dust removal component and shielding component effectively prevent dust pollution and ensure the operator's health." However, the following drawbacks still exist:
[0004] (1) The position of the polishing wheel is fixed and the distance between the polishing wheel and the shaft to be polished cannot be adjusted. Therefore, it cannot meet the surface polishing work of some crankshafts. At the same time, the distance of the connecting bracket is too long and multiple polishing wheels are installed on it. It cannot accurately polish a certain position of the gear shaft and can only polish the straight shaft.
[0005] (2) At the same time, during the clamping operation, the circumferential surface of the gear shaft is clamped and fixed, which causes the clamped part to be unable to be polished.
[0006] Therefore, we have made improvements to this and proposed a gear shaft polishing device. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0031] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0034] like Figure 1-5 As shown, this embodiment proposes a gear shaft polishing device, including an operating table 1, on which a first frame 2 and a second frame 3 are mounted. A polishing mechanism 4 is fixedly mounted on one side of the first frame, and a clamping assembly 5 is provided at the connection between the first frame and the gear shaft.
[0035] The polishing mechanism 4 includes a telescopic component 401 and a polishing component 402. The telescopic component 401 includes a fixed plate 4011, an electric pusher cylinder 4012, a telescopic shaft 4013, and a moving plate 4014. One end of the fixed plate 4011 is fixedly installed on one side of the first frame 2. The electric pusher cylinder 4012 is fixedly installed on the bottom side of the fixed plate 4011. One end of the telescopic shaft 4013 is fitted to the output end of the electric pusher cylinder 4012. One end of the moving plate 4014 is fixedly installed on the other end of the telescopic shaft 4013 by bolts, and the moving plate 4014 moves with the fixed plate 4011 via a guide rail. During the polishing process, the electric pusher cylinder 4012 operates, driving the moving plate 4014 to move on the fixed plate 4011 via the telescopic shaft 4013. Since the polishing component 402 is fixedly installed on the moving plate 4014, its entirety moves with the movement of the moving plate 4014. After the entire component is adjusted to a suitable position...
[0036] like Figure 3 As shown, the polishing component 402 includes a servo motor 4021, a polishing shaft 4022, pulleys 4023, and a belt 4024. The servo motor 4021 is fixedly mounted on the moving plate 4014. The polishing shaft 4022 is rotatably mounted on the moving plate 4014 through a bearing seat. The pulleys 4023 are respectively mounted on the same end of the servo motor 4021 and the polishing shaft 4022. The belt 4024 is tensioned and mounted on the two sets of pulleys 4023. The clamping assembly 5 includes a fixed plate 501 and grippers 502. The fixed plate 501 is mounted on the first frame 2. The number of grippers 502 is three sets and they are evenly distributed on the edge of the fixed plate 501. When the position of one end of the gear shaft is determined by the fixed plate 501, the gear shaft can be fixed by three sets of jaws 502, which can fix gear shafts of different diameters. The servo motor 4021 works, driving the polishing shaft 4022 to rotate at high speed through the pulley 4023 and belt 4024 to polish the gear shaft. By adjusting the distance between the polishing shaft 4022 and the gear shaft, it can be used to polish gear shafts of different thicknesses and crankshafts.
[0037] like Figure 1 As shown, a geared motor 6 is fixedly installed at one end of the operating table 1, and a bidirectional screw 7 is installed at the output end of the geared motor 6. The bidirectional screw 7 is connected to the bottom of the first frame 2 and the second frame 3 through a connecting seat.
[0038] like Figure 1As shown, a first fixing seat 8 is fixedly installed on the surface of the operating table 1. There are two sets of first fixing seats 8, located at the bottom of the first frame 2 and the second frame 3 respectively. The bottom of the first frame 2 is connected to the first fixing seat 8 via a guide rail. A second fixing seat 9 is installed on the first fixing seat 8 at the bottom of the second frame 3 via a guide rail, and the second frame 3 is connected to the second fixing seat 9 via a guide rail. During the polishing process, the reduction motor 6 operates, driving the bidirectional screw 7 to rotate, which in turn drives the first frame 2 and the second frame 3 to move in opposite directions or towards each other, so as to achieve the purpose of fixing gear shafts of different lengths.
[0039] like Figure 1 As shown, a hydraulic push cylinder 10 is fixedly mounted on one end of the second fixed seat 9 by bolts, and a clamping plate 11 is rotatably mounted on the output end of the hydraulic push cylinder 10. When clamping and fixing the gear shaft, if the gear shaft is too short and the displacement distance of the bidirectional screw 7 is insufficient, the hydraulic push cylinder 10 works to push the second frame 3, thereby clamping and fixing the shorter gear shaft.
[0040] like Figure 3 As shown, a high-pressure water pump 12 is fixedly installed on one side of the first frame 2. A high-pressure nozzle 13 is installed at the output end of the high-pressure water pump 12, and the high-pressure water pump 12 is connected to an external coolant tank. During the polishing process, the high-pressure water pump 12 sprays coolant onto the polishing position to prevent the gear shaft from overheating and deforming due to high-speed polishing.
[0041] like Figure 2 As shown, a lighting lamp 14 is fixedly installed on the top of the first frame 2, and the lighting lamp 14 is connected to an external power source. During polishing, the lighting lamp 14 can provide illumination for the polishing position, making it convenient for the operator to process.
[0042] Specifically, in use, when the gear shaft polishing device is in operation: At one end of the gear shaft, the position is determined by the fixing plate 501, and the gear shaft is fixed by three sets of grippers 502. The reduction motor 6 operates, driving the bidirectional screw 7 to rotate, which in turn drives the first frame 2 and the second frame 3 to move. When the gear shaft is too short and the movement distance of the bidirectional screw 7 is insufficient, the hydraulic push cylinder 10 operates, pushing the second frame 3 to clamp and fix the other end of the gear shaft. Depending on the distance between the polishing shaft 4022 and the gear shaft, the electric push cylinder 40... 12 operates by moving the movable plate 4014 on the fixed plate 4011 via the telescopic shaft 4013. Since the polishing part 402 is fixedly installed on the movable plate 4014, it will move along with the movable plate 4014. After the whole is adjusted to the appropriate position, the servo motor 4021 operates, driving the polishing shaft 4022 to rotate at high speed through the pulley 4023 and belt 4024 to polish the gear shaft. The high-pressure water pump 12 sprays coolant onto the polishing position to prevent the gear shaft from overheating and deforming due to high-speed polishing.
[0043] All technical features in this embodiment can be freely combined according to actual needs.
[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
