Description

Technical Field

[0001] This utility model relates to the technical field of metallographic sample polishing machines, specifically a protective device for metallographic sample polishing machines. Background Technology

[0002] As is well known, the performance research of existing metallic materials plays a vital role in the development of various fields. Metallographic analysis, as an important technical means to explore the microstructure, composition distribution and defect characteristics of metallic materials, is widely used in high-end manufacturing industries such as aerospace, automobile manufacturing and machining.

[0003] In the metallographic specimen preparation process, polishing is a crucial step to ensure the quality of the specimen surface. Currently, metallographic specimen polishing machines mostly use high-speed rotating polishing discs, along with polishing fluid and abrasives, to grind and polish the specimen surface. However, this polishing method has many safety hazards and efficiency issues in actual operation.

[0004] On the one hand, the high-speed rotating polishing disc generates strong centrifugal force, causing polishing fluid and abrasive particles to splash everywhere. These splashed polishing fluids not only pollute the working environment and corrode the equipment surface, but also may cause chemical burns or other injuries if they accidentally splash into the operator's eyes or skin. At the same time, the flying abrasive particles are very easy for operators to inhale into their respiratory tract, and long-term exposure may cause occupational diseases such as pneumoconiosis, seriously threatening the health of operators.

[0005] On the other hand, existing polishing machines rely on manual hand-holding or simple fixation methods to fix the sample, which makes it difficult to ensure the stability of the sample during high-speed polishing. Under the centrifugal force of the polishing disc, the sample may be thrown out, which may not only damage the sample but also cause serious accidental injury to the operator. Utility Model Content

[0030] Please see Figure 1-4 A protective device for a metallographic sample polishing machine includes a machine 2, a polishing disc 14 disposed on the upper side of the machine 2, mounting plates 6 disposed on both side walls of the machine 2, a switch assembly disposed on the mounting plate 6, a protective shell 1 disposed between the switch assemblies, the protective shell 1 being adapted to the upper side wall of the machine 2, a collection tray 15 disposed around the polishing disc 14, a drain pipe 5 disposed on one side of the bottom wall of the collection tray 15, the drain pipe 5 penetrating the bottom wall of the collection tray 15 and the side wall of the machine 2, a suction cup manipulator 13 disposed at one end of the upper side wall of the machine 2, and a suction cup manipulator 13 disposed at the other end. The water spray assembly includes a water spray pipe 11 and a water spray head 12. One end of the water spray pipe 11 passes through the side wall of the machine 2, and the other end is connected to the water spray head 12. The water spray pipe 11 is a universal shaped water pipe. The front side wall of the machine 2 is provided with a display screen 3 and control buttons 4 for controlling the above-mentioned devices. The suction cup manipulator 13 is provided with a pressure sensor, which is electrically connected to the display screen 3 for real-time monitoring of the adsorption pressure value. The outer layer of the universal shaped water pipe is a stainless steel braided mesh, and the inner layer is a polytetrafluoroethylene hose. A miniature water pump is provided on the water spray head 12.

[0031] During use, the operator first symmetrically fixes the mounting plate 6 to both sides of the machine 2 with screws to ensure structural stability. Then, the metallographic sample to be polished is placed in the designated position on the polishing disc 14. At this time, the suction cup robot 13 is started by operating the display screen 3 and control button 4. The negative pressure system inside the suction cup robot 13 starts working. Under the real-time monitoring of the pressure sensor, the suction pressure is gradually adjusted to the preset value to ensure that the sample is firmly clamped and to prevent displacement or flying out during high-speed polishing.

[0032] Then, the switch assembly is activated, causing the protective shell 1 to descend smoothly. Once the protective shell 1 is fully in contact with the upper side wall of the machine 2, a closed working space is formed, effectively preventing the spillage of splatter generated during the polishing process.

[0033] The operator inputs polishing parameters, such as the polishing disc rotation speed, polishing time, and water spray pressure, through the display screen 3 and control buttons 4. These parameters are then transmitted to the control system of the machine 2 for processing.

[0034] The control system starts the polishing disc 14 according to preset parameters, causing it to rotate at high speed. Simultaneously, one end of the water spray pipe 11 is connected to the polishing liquid storage container, and the water spray assembly begins operation. A micro water pump draws the polishing liquid from the storage container and delivers it to the water spray head 12 through a universal water hose. The operator can adjust the bending angle and position of the universal water hose in advance according to actual needs to ensure that the water spray head 12 is precisely aimed at the polishing area, achieving effective cooling and cleaning during the polishing process.

[0035] During the polishing process, the wastewater generated, carrying abrasive particles and other impurities, flows into the collection tray 15 around the polishing disc 14, and is discharged from the machine 2 through the drain pipe 5 for centralized treatment.

[0036] Once the polishing time reaches the preset value, the control system sequentially stops the work of the polishing disc 14, the water spray assembly, and the suction cup robot 13. Then, the switch assembly is restarted to make the protective shell 1 rise smoothly. After the protective shell 1 is fully opened, the operator takes out the polished sample, completing the entire polishing process. Finally, it can be cleaned and prepared for the next use.

[0037] Machine 2 is a common metallographic sample polishing machine on the market. It has basic sample polishing functions and is usually composed of core components such as base, drive motor 7, and polishing disc 14. Drive motor 7 can drive polishing disc 14 to rotate at high speed, providing power for sample polishing. It is a common device on the market and will not be described in detail in this article.

[0038] In practical use, automatic opening and closing of the protective shell 1 is required. To meet this requirement, in this embodiment, the switch assembly includes a limiting box 8, a sliding rod 17, a control rod 16, a control block 18, and a motor 7. The limiting box 8 is symmetrically arranged on the upper side wall of the mounting plate 6. The sliding rod 17 and the control rod 16 are arranged parallel to each other inside the limiting box 8. The motor 7 is located at the lower end of one of the mounting plates 6. The control rod 16 passes through the mounting plate 6 and is connected to the output end of the motor 7. The control blocks 18 are symmetrically arranged. The control rod 16 passes through one of the control blocks 18 and is threadedly connected to it. The sliding rod 17 passes through the other control block 18 and is slidably connected to it. The control blocks 18 are fitted against and slidably connected to the inner side wall of the limiting box 8. One end of each control block 18 is connected to the side wall of the protective shell 1.

[0039] When the motor 7 is started, the output shaft of the motor 7 drives the control rod 16 to rotate. Since the control rod 16 is threadedly connected to one of the control blocks 18 and the other control block 18 is slidably connected to the sliding rod 17, during the rotation of the control rod 16, the two control blocks 18 will move towards each other along the limit box 8, thereby driving the protective shell 1 to rise and fall.

[0040] In practical use, it is necessary to facilitate the insertion of vacuum cleaning tools. To meet the above requirements, in this embodiment, an opening 10 is provided at the center of the upper side wall of the protective shell 1, and a removable sealing plug 9 is provided on the opening 10.

[0041] If a lot of dust is generated during the polishing process, the operator can open the sealing plug 9 on the protective shell 1 and connect an external vacuum cleaner to further adsorb the dust in the work space and keep the working environment clean. During this process, the pressure sensor continuously monitors the adsorption pressure of the suction cup robot 13 and transmits the data to the display screen 3 in real time. The operator can check the pressure value at any time through the display screen 3 to ensure that the adsorption pressure is always within a safe range. If the pressure value fluctuates abnormally, the system will automatically issue an alarm to prompt the operator to check and adjust.

[0042] In actual use, it is necessary to improve the durability of the equipment and the comfort of the operating environment in all aspects. In order to meet the above requirements, in this embodiment, the protective shell 1 is made of double-layer transparent PC material, the inner layer is an anti-static layer, the outer layer is a wear-resistant layer, and a sound insulation cotton interlayer is provided between the two layers.

The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
