Description

Technical Field

[0001] This utility model belongs to the field of polishing equipment technology, specifically relating to a multi-station polishing disc changing device. Background Technology

[0002] Polishing discs are a process that uses polishing discs installed on polishing equipment to process the surface of workpieces through friction or grinding. The polishing discs are driven by power to rotate or reciprocate. With the help of their own material properties or polishing agents, they produce cutting and grinding effects on the surface of the workpiece, removing defects such as burrs, scratches, and oxide layers, and finally making the surface achieve the required smoothness, flatness or gloss. Polishing discs of different materials are suitable for different stages such as rough polishing and fine polishing, and are widely used in surface treatment in the manufacturing industry.

[0003] However, traditional polishing equipment relies on polishing discs to complete the polishing process during operation. When facing different polishing requirements, the polishing discs must be changed. This changeover process is often cumbersome and cannot be achieved through multi-station design to efficiently switch polishing discs, thus making it difficult to achieve the convenience of polishing operations. This limitation not only affects processing efficiency but also increases the complexity of operation. In particular, the problem of frequent manual disc changes is more prominent in mass production.

[0004] To address the aforementioned issues, this application proposes a multi-station polishing disc changing device. Utility Model Content

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.

[0025] Example

[0026] Please see Figure 1-7 The present invention provides the following technical solution: a multi-station polishing disc changing device, including a support frame 1, a sliding frame 2 slidably connected inside the support frame 1, a controller 3 fixedly connected to the left side of the support frame 1, two first electric push rods 8 arranged above the sliding frame 2, a second electric push rod 10 arranged below the sliding frame 2, three third electric push rods 13 arranged on the right side of the support frame 1, a fourth electric push rod 15 fixedly connected to the telescopic end of each third electric push rod 13, a mounting plate 16 fixedly connected to the telescopic end of each fourth electric push rod 15, a rotary motor 18 arranged below each mounting plate 16, and a polishing disc 14 fixedly connected to the power output end of each rotary motor 18;

[0027] In this embodiment, the controller 3 uses a programmable logic controller (PLC), which is a digital computing and operating electronic system designed specifically for industrial environments. It has a built-in programmable memory that can store and execute operation instructions such as logic operations, sequential control, timing, counting, and arithmetic operations. Through digital or analog input / output interfaces, it can achieve precise control of various machines or production processes. At the same time, in conjunction with three different types of polishing discs 14, it can efficiently realize multi-station polishing disc changing function, further improving the automation control level and operation efficiency of the equipment.

[0028] Specifically, two sets of connecting columns 5 are fixedly connected to the bottom surface of the support frame 1. Each connecting column 5 is fixedly connected to a support ring 4 at its bottom end. In this embodiment, the combination structure of the connecting column 5 and the support ring 4 can provide a stable support foundation for the entire device. The connecting column 5 evenly transfers the weight of the support frame 1 to the support ring 4, while the support ring 4 increases the contact area with the ground, effectively dispersing the overall pressure of the device and avoiding displacement or tilting caused by equipment vibration during the polishing operation, thus ensuring the stability of the processing process.

[0029] Specifically, each of the two first electric push rods 8 has a fixed plate 7 fixedly connected to one end of each other. The bottom surface of each fixed plate 7 is fixedly connected to the upper surface of the sliding frame 2. In this embodiment, the first electric push rods 8 are securely installed on the sliding frame 2 by the fixed plate 7. The fixed plate 7 increases the connection area between the first electric push rods 8 and the sliding frame 2, improves the connection strength, and ensures that the first electric push rods 8 will not shake or deviate during the extension and retraction operation, thus ensuring that the clamping force on the workpiece is stable and reliable, and providing structural guarantee for the accuracy of subsequent polishing processing.

[0030] Specifically, each of the telescopic ends of the first electric push rod 8 is fixedly connected to a protective pad 9, and each protective pad 9 is made of rubber. In this embodiment, the protective pad 9 made of rubber can enhance the friction between the first electric push rod 8 and the workpiece, improve the stability of clamping, and avoid the rigid contact from causing squeezing damage to the surface of the workpiece. The rubber material has good elasticity and cushioning performance, which can adapt to the clamping requirements of workpieces of different shapes, while reducing the displacement of the workpiece caused by vibration during the polishing process and protecting the workpiece processing accuracy.

[0031] Specifically, a fixing frame 6 is fixedly connected to the end of the second electric push rod 10 away from the controller 3. The bottom surface of the fixing frame 6 is fixedly connected to the inner bottom wall of the support frame 1. In this embodiment, the second electric push rod 10 is firmly fixed to the support frame 1 by the fixing frame 6. The fixing frame 6 provides a stable installation base for the second electric push rod 10, ensuring that it will not move when driving the sliding frame 2 to move, ensuring the stability and accuracy of the thrust transmission, so that the sliding frame 2 can move accurately to the target work position according to the preset trajectory.

[0032] Specifically, the telescopic end of the second electric push rod 10 is fixedly connected to a connecting plate 11. The upper surface of the connecting plate 11 is fixedly connected to the bottom surface of the sliding frame 2. In this embodiment, the connection between the second electric push rod 10 and the sliding frame 2 is achieved through the connecting plate 11. The connecting plate 11 increases the contact area between the two, so that the thrust of the second electric push rod 10 can be evenly transmitted to the sliding frame 2, avoiding deformation or damage to the sliding frame 2 due to force concentration. At the same time, it ensures the stability of the sliding frame 2 during movement and ensures that the workpiece can be accurately aligned with the polishing disc 14.

[0033] Specifically, a support plate 12 is fixedly connected to the bottom surface of each third electric push rod 13, and the left side of each support plate 12 is fixedly connected to the right side of the support frame 1. In this embodiment, the third electric push rod 13 is stably installed on the support frame 1 by the support plate 12. The support plate 12 provides a solid support for the third electric push rod 13, which can withstand the reaction force generated during its extension and retraction operation, prevent the third electric push rod 13 from shaking or tilting, ensure the accuracy of the position adjustment of the polishing disc 14, and ensure the stability of the polishing process.

[0034] Specifically, each rotary motor 18 has a connecting seat 17 fixedly connected to its outer surface. The upper surface of each connecting seat 17 is fixedly connected to the bottom surface of the mounting plate 16. In this embodiment, the rotary motor 18 is securely mounted on the mounting plate 16 through the connecting seat 17. The connecting seat 17 enhances the connection strength between the rotary motor 18 and the mounting plate 16, effectively absorbing the vibration generated when the rotary motor 18 is working, avoiding the motor from loosening or shifting due to vibration, ensuring the rotational stability of the polishing disc 14, and improving the precision and consistency of the polishing process.

[0035] The working principle and usage process of this utility model are as follows: In use, the equipment is first started via controller 3, and the workpiece to be polished is placed at the designated position on the sliding frame 2. Then, controller 3 controls the two first electric push rods 8 to extend synchronously. The protective pads 9 at their telescopic ends tightly adhere to both sides of the workpiece, utilizing the properties of the rubber material to achieve a stable clamping of the workpiece, preventing both loosening and surface damage. Next, according to the preset polishing process, controller 3 drives the second electric push rod 10 to extend and retract, causing the sliding frame 2 to slide along the inside of the support frame 1 via the connecting plate 11, precisely transferring the workpiece below the first polishing disc 14. Simultaneously, the third electric push rod 13 and the fourth electric push rod 15 at the corresponding workstations work together to adjust the position and height of the mounting plate 16 and the rotary motor 18, ensuring that the polishing disc 14 maintains a suitable polishing pressure on the workpiece surface. Afterwards… The rotary motor 18 starts, driving the polishing disc 14 to rotate at high speed to perform the first polishing treatment on the workpiece. After completion, the second electric push rod 10 drives the sliding frame 2 to move, sending the workpiece to the second polishing disc 14. The third electric push rod 13 and the fourth electric push rod 15 work together to adjust the position, and the corresponding polishing disc 14 completes the intermediate polishing process. Similarly, the workpiece continues to be moved to the third polishing disc 14 to complete the fine polishing. Throughout the process, the controller 3 precisely coordinates the actions of each component through the PLC program to realize automatic disc switching for multi-station polishing. After polishing is completed, the first electric push rod 8 resets and releases the workpiece, and the second electric push rod 10 brings the sliding frame 2 back to the initial position, allowing the operator to remove the workpiece. When the device is running, the connecting column 5 and the support ring 4 ensure overall stability, and the various fixed and supporting structures ensure the smooth operation of the power components, effectively improving polishing efficiency and quality.
