Description

Technical Field

[0001] This utility model relates to the technical field of parts polishing devices, and in particular to a polishing device for irregularly shaped parts. Background Technology

[0002] In modern manufacturing, irregularly shaped parts are increasingly widely used, ranging from precision components in the aerospace field to special structural parts in electronic equipment. These applications place stringent demands on the machining accuracy and surface quality of irregularly shaped parts. Among these processes, polishing is a key step in improving the surface finish of irregularly shaped parts, eliminating machining marks, and enhancing their durability and aesthetics. The level of polishing technology directly affects the overall performance and market competitiveness of the product.

[0003] Currently, traditional polishing techniques for irregularly shaped parts face numerous challenges. The part-fixing process relies heavily on manual operation, which is not only inefficient but also makes it difficult to guarantee the accuracy of the fixing position each time. This causes the parts to easily shift during polishing, severely affecting the consistency of polishing quality and resulting in a high defect rate.

[0004] During the polishing process, traditional equipment often struggles to meet the complex surface treatment needs of irregularly shaped parts. Some equipment can only polish local surfaces of regular shapes, failing to achieve a comprehensive and uniform polishing effect for irregularly shaped parts with large curvature variations, resulting in inconsistent polishing quality.

[0005] Furthermore, existing technologies have significant shortcomings in the part flipping operation. When polishing different surfaces of irregularly shaped parts, it is usually necessary to manually flip the parts and reposition them. This process not only consumes a lot of time and severely reduces production efficiency, but is also highly susceptible to damage to parts due to human error, further increasing production costs. Therefore, those skilled in the art have provided a polishing device for irregularly shaped parts to solve the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a polishing device for irregularly shaped parts. To achieve the above objective, this utility model provides the following technical solution: It includes a chassis, with a first sliding groove formed at the center of the top of the chassis. The device is characterized by a limiting plate installed on the front side of the top of the chassis, located on one side of the first sliding groove. A first cylinder is connected through the front wall of the limiting plate. The output end of the first cylinder is connected to a lifting adjustment base. The sliding end of the lifting adjustment base is movably connected to the inner wall of the first sliding groove. A mounting seat is installed on the top of the lifting adjustment base. A first motor is installed on the top of the mounting seat. A transmission device is connected to the output end of the first motor. A telescopic seat is installed on one side wall of the transmission device, located near the limiting plate. The output end of the telescopic seat is connected to a fixing mechanism. A second sliding groove is formed at the bottom of the fixing mechanism, near the center. A first lead screw is rotatably connected to the middle of the inner sidewall of the second slide groove. A slider is threadedly connected to the outer sidewall of the first lead screw. A second cylinder is installed at the middle of the bottom of the slider. A clamping fixture is installed at the bottom of the second cylinder. A second motor is connected to the input end of the first lead screw. The second motor is installed at the middle of one sidewall of the fixing mechanism. A fixed roller is installed at the middle of the top of the housing near the front side. An adjusting roller is installed behind the fixed roller and at the top of the housing. A driven wheel is connected to the input end of the adjusting roller. A drive wheel is installed on one sidewall of the housing below the driven wheel. A driver is connected to the input end of the drive wheel. The driver is installed on the inner sidewall of the housing. A transmission chain is sleeved on the outer sidewall of the drive wheel and the driven wheel. A second slide groove is opened at the bottom of the fixing mechanism, and a first lead screw is built in it and driven by the second motor. A second cylinder and a clamping fixture are installed at the bottom of the slider threaded to the outer sidewall of the lead screw. It can accurately position and firmly fix irregularly shaped parts. All components work together to quickly adapt to irregularly shaped parts of different sizes. Compared with traditional fixing methods, it is more convenient to adjust and more stable to fix. When it is necessary to flip the parts, the controller will precisely control the polishing mechanism (including the first motor, the transmission device, the transmission tube, and the polishing blade) and the clamping mechanism (the second motor, the first lead screw, the second cylinder, and the clamping fixture) to stop working. After the adjusting roller completes the flip, the relevant mechanisms will continue to work.

[0007] Preferably, the polishing blade is equipped with a semi-circular arc-shaped cutting protective cover, which can effectively block the flying debris generated during the polishing process, prevent injury to the operator, and ensure a safe working environment. This is a key safety protection measure that is often lacking in traditional polishing equipment.

[0008] Preferably, the feeding and lifting device automatically lifts the parts from a low position to the corresponding position in the chassis. Compared with traditional manual handling and feeding, it greatly improves the feeding efficiency and can accurately control the feeding position, reducing human error.

[0009] Preferably, the third motor drives the second lead screw, which is threaded onto the outer wall of the lifting seat, and a U-shaped frame is installed on top. This design can automatically lift parts from a low position to the corresponding position in the machine casing, greatly improving loading efficiency compared to traditional manual handling and loading, and allowing for precise control of the loading position, reducing human error.

[0010] Preferably, the output end of the third cylinder is connected to a discharge pusher plate. When the lifting seat reaches the preset position, the third cylinder responds quickly, pushes the discharge pusher plate, and accurately sends the part into the machine box, so that it falls steadily between the fixed roller and the adjusting roller.

[0011] Preferably, the operating parameters of each component of the device can be adjusted or preset via the controller.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the polishing mechanism (first motor, transmission device, transmission tube, polishing blade) and the clamping mechanism (second motor, first lead screw, second cylinder, clamping fixture) automatically pause when the adjusting roller flips the part, thanks to the precise control of the controller. The work resumes immediately after the flip is completed, with seamless connection, reducing downtime and increasing the processing volume per unit time. The first cylinder pushes the lifting adjustment base to be precisely positioned in the first slide groove, and the telescopic seat drives the fixing mechanism to approach the part. The second motor controls the first lead screw to make the clamping fixture automatically adjust its position and fix the part. The whole process is fast and precise, reducing waiting time and laying the foundation for efficient production.

[0014] 2. In this utility model, the feeding and lifting device is driven by a third motor to drive a second lead screw, which in turn drives the lifting seat to move up and down precisely along the third slide groove. From the moment the part is placed on the top of the U-shaped frame to its precise delivery between the fixed roller and the adjusting roller inside the machine box, the entire process is automated, enabling continuous and rapid feeding, greatly shortening the feeding cycle and improving overall production efficiency.

[0015] 3. In this utility model, the operations of feeding, fixing, polishing, and flipping are integrated into an automated system. The operator only needs to place the parts on the top of the U-shaped frame, and the subsequent process is completed automatically, reducing operation steps, reducing labor intensity, and improving work comfort.

The second cylinder 22 and the clamping fixture 23 are installed at the bottom of the slider threadedly connected to the outer wall of the screw. This mechanism can accurately position and firmly fix irregularly shaped parts. The components work together to quickly adapt to irregularly shaped parts of different sizes. Compared with traditional fixing methods, it is more convenient to adjust and more stable to fix. When it is necessary to flip the parts, the controller 5 will precisely control the polishing mechanism, including the first motor 14, the transmission device 13, the transmission tube 15, the polishing blade 16, the clamping mechanism, the second motor 19, the first lead screw 21, the second cylinder 22, and the clamping fixture 23, to stop working. After the adjusting roller 9 completes the flipping, the relevant mechanisms will continue to work.

[0023] The output end of the actuator 13 is connected to the drive pipe 15, and the output of the drive pipe 15 is connected to the polishing blade 16. The outer wall of the polishing blade 16 is fitted with a cutting protective cover, which is semi-circular. The polishing blade 16 is preferably equipped with a semi-circular cutting protective cover, which can effectively block the flying debris generated during the polishing process, prevent injury to the operator, and ensure a safe working environment. This is a key safety protection measure that is often lacking in traditional polishing devices. A feeding lifting device 24 is installed on one side wall of the machine box 1, located at the other end of the adjusting roller 9 and the fixed roller 10. It automatically lifts the parts from the low position to the corresponding position of the machine box 1. Compared with the traditional manual handling and feeding, it greatly improves the feeding efficiency and can accurately control the feeding position, reducing human error.

[0024] A third chute 25 is provided on one side wall of the feeding and lifting device 24. A second lead screw 26 is rotatably connected to the middle of the inner side wall of the third chute 25. A third motor is connected to the input of the second lead screw 26. The third motor is installed at the bottom middle of the third chute 25. A lifting seat 27 is threadedly connected to the outer side wall of the second lead screw 26, and the third motor drives it. A U-shaped frame 28 is installed on the top of the second lead screw 26. This design can automatically lift parts from a low position to the corresponding position in the housing 1. Compared with traditional manual handling and loading, it greatly improves loading efficiency and can accurately control the loading position, reducing human error. A U-shaped frame 28 is installed at the top middle position of the lifting seat 27. A third cylinder 30 is installed on one side wall of the U-shaped frame 28. The output end of the third cylinder 30 passes through the middle of the inner side wall of the U-shaped frame 28. The output end of the third cylinder 30 is connected to the unloading push plate 29. When the lifting seat 27 reaches the preset position, the third cylinder 30 responds quickly and pushes the unloading push plate 29 to accurately send the parts into the housing 1, so that they fall steadily between the fixed roller 10 and the adjusting roller 9.

[0025] A controller 5 is installed on one side of the front wall of the chassis 1. The controller 5 is electrically connected to the third cylinder 30, the first motor 14, the second motor 19, the second cylinder 22, the telescopic seat 17, the first cylinder 4, and the third motor. The controller 5 can be used to adjust or preset the operating parameters of each component of the device.

[0026] Working principle: The irregularly shaped part to be processed is placed on top of the U-shaped frame 28. At this time, the feeding and lifting device 24 starts to operate, and the third motor starts quietly, driving the second lead screw 26 to rotate smoothly in the third slide 25. The lifting seat 27, which is threadedly connected to the second lead screw 26, is as if given the command to rise, and slowly climbs up along the slide, sending the part carried on the U-shaped frame 28 to the designated height. When the lifting seat 27 reaches the preset position, the third cylinder 30 responds quickly, pushing the unloading push plate 29, accurately sending the part into the machine box 1, so that it falls steadily between the fixed roller 10 and the adjusting roller 9.

[0027] Next, the fixing process begins. The first cylinder 4 extends, pushing the lifting and adjusting base 11 to slide within the first slide groove 2, adjusting it to a suitable height and position. The telescopic base 17 also extends, driving the fixing mechanism 18 closer to the part. Subsequently, the second motor 19 operates, driving the first lead screw 21 to rotate, allowing the slider to find a precise lateral position within the second slide groove 20, preparing for the descent of the clamping fixture 23. With the activation of the second cylinder 22, the clamping fixture 23 slowly descends, firmly securing the part.

[0028] During the polishing process, the driver is activated, and the drive wheel 6 begins to rotate. This drives the driven wheel 8 through the transmission chain 7, which in turn causes the adjusting roller 9 and the fixed roller 10 to work together, moving the part forward. At the same time, the first motor 14 drives the transmission device 13, the transmission tube 15, and the polishing blade 16 to rotate at high speed, performing meticulous polishing on the moving part.

[0029] The innovative features of this device become apparent when it needs to flip irregularly shaped parts. Controller 5 acts like a smart commander, quickly issuing commands to pause the polishing and clamping mechanisms. The adjusting roller 9 then uses its rotational characteristics to smoothly flip the part. Once the flipping is complete, controller 5 issues another command, restarting the polishing and clamping mechanisms to continue polishing the part. Throughout the process, a cutting guard constantly protects against flying debris from polishing. Without frequent manual intervention, the device significantly improves production efficiency thanks to the coordinated operation of its components under the control of controller 5.

[0030] 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.
