Description
Technical Field
[0001] This utility model specifically relates to the field of automated metallographic grinding machine technology, and more specifically to a detachable automated metallographic grinding machine that is easy to clean. Background Technology
[0002] In the field of metallographic analysis, metallographic grinding machines are key equipment for sample preparation. Traditional single-station grinding machines are inefficient and cannot meet the needs of batch testing. Moreover, the grinding discs and protective components of most machines are integrated or difficult to disassemble, and the grinding debris and grinding fluid residue generated during the grinding process easily adhere to the surface of the components. Cleaning requires stopping the machine for disassembly, which is complicated, time-consuming, and can easily affect the grinding accuracy of subsequent samples due to incomplete cleaning, and may even lead to component wear and corrosion, shortening the life of the equipment. At the same time, if multi-station equipment lacks a reasonable detachable and flow-guiding design, the problems of waste liquid splashing and accumulation are more prominent, restricting the efficiency and quality of metallographic sample preparation.

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.
[0034] Please see Figure 1-10 In this embodiment of the utility model, a detachable and easy-to-clean automated metallographic grinding machine includes...
[0035] A dual-station grinding base 1, with a grinding machine assembly 2 installed at the rear end and a grinding disc assembly 3 symmetrically installed at the front end; the grinding machine assembly 2 is provided on the upper end of the symmetrically arranged grinding disc assembly 3.
[0036] The grinding disc assembly 3 includes a drive motor 31, the lower end of which is connected to one end of a transmission mechanism 32. The other end of the transmission mechanism 32 is connected to a lead screw at the lower end of the grinding disc base 33. The grinding disc base 33 is mounted on a mounting bracket 34, and a bearing is provided inside the mounting bracket 34.
[0037] A base 35 is fixedly mounted on the mounting bracket 34. An opening is provided in the base 35, and the upper surface of the base 35 is connected to the annular protective ring 36. The upper end of the grinding disc base 33 is located inside the annular protective ring 36.
[0038] The annular protective ring 36 has a drain port 37 on one side, and an arc-shaped groove 38 is symmetrically installed on the outer side of the upper end.
[0039] By adopting the above technical solution, when disassembling the grinding disc base 33, the arc-shaped slide groove 38 and the arc-shaped slide rail 13 are connected to the screw screw unscrewed structure at the lower end of the grinding disc base 33. Operators can disassemble key components such as the chassis 35 and the annular protective ring 36 without the need for professional tools. Compared with traditional equipment disassembly, which requires the removal of multiple sets of screws, the disassembly convenience is greatly improved.
[0040] After the components such as the grinding disc base 33, the chassis 35 and the annular protective ring 36 are separated, the traditional cleaning blind spots such as the bottom surface of the grinding disc base 33, the chip accumulation area inside the annular protective ring 36, and the opening gaps of the chassis 35 are completely exposed. With the help of high-pressure water guns and ultrasonic cleaning, micron-sized metal chips and grinding fluid crystals can be removed, solving the long-standing problem of sample contamination caused by cleaning dead spots in the industry and ensuring the cleanliness of the equipment's interior.
[0041] The annular protective ring 36 effectively prevents the splashing of grinding fluid from corroding the internal circuitry and transmission components of the main unit; the detachable structure facilitates timely cleaning of grinding debris, preventing it from entering the transmission mechanism 32 and the drive motor 31 bearings, thus reducing abnormal wear of components.
[0042] In this embodiment, the drive motor 31 is fixedly mounted on the upper surface of the mounting bracket 12, the mounting bracket 12 is fixedly located on the inner side of the rear end of the dual-station main unit 11, and the front end of the dual-station main unit 11 has symmetrical circular connecting seats for mounting the grinding disc assembly 3.
[0043] The dual-station main unit base 11 has two sets of arc-shaped slide rails 13 symmetrically arranged on the upper surface of the front end. Each set of symmetrically arranged arc-shaped slide rails 13 is located on both sides of the circular connecting seat. The dual-station main unit base 11 also has grinding liquid nozzles 14 symmetrically installed on the upper surface of the front end.
[0044] The symmetrically arranged arc-shaped slide rail 13 is slidably connected to the symmetrically arranged arc-shaped slide groove 38; the front end of the dual-station main unit 11 is symmetrically provided with a drain port 15, and the other end of the drain port 15 is connected to the drain interface 37.
[0045] The dual-station main unit base 11 is equipped with a lifting drive rod 21 at its rear end. The upper end of the lifting drive rod 21 is connected to the support column 22. The front end of the support column 22 is rotatably connected to a cantilever beam 23. A grinding power box 24 is installed on the inner side of the cantilever beam 23. The lower end of the grinding power box 24 is connected to the sample clamping plate 25 and the grinding head connecting seat 26 respectively.
[0046] By adopting the above technical solution, the dual workstations can be loaded with grinding discs of different particle sizes, such as coarse grinding and fine grinding discs. With the 24-speed adjustment of the grinding power box, the entire process of coarse grinding, fine grinding and polishing of metallographic samples can be completed in one stop without frequent equipment changes. It is suitable for diverse scenarios such as material research and development and quality inspection.
[0047] The working principle of this utility model is as follows: a circular connecting seat is symmetrically arranged at the front end of the dual-station main unit 11, which carries two sets of independent grinding disc assemblies 3; the drive motor 31 runs and the power is converted by the transmission mechanism 32 to drive the grinding disc base 33 to rotate at high speed; at the same time, the lifting drive rod 21 of the grinding machine assembly 2 controls the linkage of the support column 22 and the cantilever beam 23 to realize synchronous or independent grinding in both stations, which can meet the needs of parallel processing of multiple samples.
[0048] During cleaning, the grinding disc base 33 can be quickly separated by rotating upwards through the screw thread engagement structure between the bottom lead screw and the mounting bracket 34 and the transmission mechanism 32. Utilizing the sliding and rotating adaptation design of the arc-shaped slide groove 38 and the arc-shaped slide rail 13 of the dual-station main unit base 11, components such as the chassis 35, the annular protective ring 36, and the drain port 37 can be completely disassembled, fully exposing the internal cleaning surface of the equipment for deep cleaning.
[0049] The grinding fluid nozzle 14 supplies grinding fluid precisely as needed. The annular protective ring 36 guides the waste liquid to the drain port 37 through the annular enclosure structure, and then discharges it through the drain port 15 of the dual-station main unit base 11.
[0050] When disassembling the grinding disc base 33, the arc-shaped slide groove 38 and the arc-shaped slide rail 13 are connected to the screw screw unscrewed structure at the lower end of the grinding disc base 33. Operators can disassemble key components such as the chassis 35 and the annular protective ring 36 without the need for professional tools. Compared with traditional equipment disassembly, which requires the removal of multiple sets of screws, this greatly improves the convenience of disassembly.
[0051] After the components such as the grinding disc base 33, the chassis 35 and the annular protective ring 36 are separated, the traditional cleaning blind spots such as the bottom surface of the grinding disc base 33, the chip accumulation area inside the annular protective ring 36, and the opening gaps of the chassis 35 are completely exposed. With the help of high-pressure water guns and ultrasonic cleaning, micron-sized metal chips and grinding fluid crystals can be removed, solving the long-standing problem of sample contamination caused by cleaning dead spots in the industry and ensuring the cleanliness of the equipment's interior.
[0052] The annular protective ring 36 effectively prevents the splashing of grinding fluid from corroding the internal circuitry and transmission components of the main unit; the detachable structure facilitates timely cleaning of grinding debris, preventing it from entering the transmission mechanism 32 and the bearings of the drive motor 31, and reducing abnormal wear of components.
[0053] The dual-station design allows for the separate loading of grinding discs of different grit sizes, such as coarse and fine grinding discs. Combined with the 24-speed adjustable grinding power box, it can complete the entire process of coarse grinding, fine grinding, and polishing of metallographic samples in one stop, without the need for frequent equipment changes. It is suitable for diverse scenarios such as material research and development and quality inspection.
