DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Referring to Figures 1-4 , an integrated metallographic inspection device includes a water tank 1 filled with clear water. A plurality of grinding disks 2 and pickling cups 3 are annularly distributed on the outer side of the water tank 1. Above the grinding disks 2, there is a clamping assembly capable of driving the sample to rotate, which is used to clamp the sample and cooperate with the grinding disks 2 to grind and polish the sample. The sample is ground by the different grinding roughnesses set by the plurality of grinding disks 2, and the acid solution in the pickling cup 3 is set according to actual needs to achieve different corrosion effects on the sample, ensuring the effect of metallographic inspection.

[0027] A vertical column 4 is installed vertically in the middle of the water tank 1. The upper end of the vertical column 4 is rotatably installed with a cantilever 5, and a driving motor for driving the cantilever 5 to rotate is provided in the vertical column 4. A telescopic cylinder 6 is vertically installed on one side of the cantilever 5, and the clamping assembly is installed on the telescopic end of the telescopic cylinder 6. The driving motor drives the cantilever 5 to rotate, and then drives the clamping assembly to move to the designated grinding disks 2 and pickling cups 3, and the height of the clamping assembly is adjusted by the telescopic cylinder 6 for corresponding grinding and pickling, facilitating the control of the grinding of the sample.

[0028] A water spray pipe 8 is further provided below the cantilever 5. The water outlet end of the water spray pipe 8 is arranged corresponding to the clamping assembly, and a water pump for supplying water to the water spray pipe 8 is provided in the water tank 1. The water spray pipe 8 cools or cleans the sample during the grinding of the sample or after pickling, controls the pickling time of the sample, and ensures the quality of metallographic corrosion. One of the pickling cups 3 can also be set for waste liquid collection to collect the waste water for cleaning the acid solution.

[0029] Based on the above technical solutions, when it is necessary to perform metallographic inspection on a sample, the sample is fixed on the clamping assembly and the surface to be inspected is kept as horizontal as possible to ensure the grinding effect. The driving motor is started to drive the cantilever 5 to rotate to the designated grinding disk 2, and the sample is lowered to a suitable position by the telescopic cylinder 6 and the sample is rotated at a certain speed to grind the sample. During grinding, clear water is sprayed on the sample through the water spray pipe 8 as needed. According to the needs of metallographic inspection, the metallographic sample is ground and polished by a plurality of grinding disks 2 with different roughnesses. After polishing, the sample is moved to the pickling cup 3 for pickling the sample. The pickling time is controlled. After reaching the appropriate corrosion time, the sample is moved to a suitable position, and the water spray pipe 8 is started to spray clear water to wash away the acid solution, ensuring the metallographic corrosion effect.

[0030] In this technical solution, as Figures 1-4As shown, an installation frame 21 is provided inside the grinding disc 2. A friction plate 22 is installed on the installation frame 21. A splash-proof wall 23 is provided on the side wall of the grinding disc 2. A return pipe 24 that is connected to the side wall of the water tank 1 in a penetrating manner is provided at the lower end of the grinding disc 2. The friction plate 22 is installed by the installation frame 21. The friction plate 22 can be a grinding wheel, a polishing plate, a felt, etc., for grinding and polishing the sample. The installation frame 21 also facilitates the flow of water and its return to the water tank 1 through the return pipe 24. After pickling, the sample can also be moved to the outside of the friction plate 22 and cleaned by the water spray pipe 8, and the waste water is returned to the water tank 1 for unified treatment. Through the design of the splash-proof wall 23, it can prevent the grinding wheel, sample debris, etc. from flying out during grinding and ensure the cleanliness of the surrounding environment.

[0031] In this technical solution, as Figures 1-3 shown, the clamping assembly includes a mounting plate 61 fixed to the telescopic end of the telescopic cylinder 6, a small motor 7 vertically installed on the mounting plate 61, and a chuck 71 installed on the output end of the small motor 7 for clamping the sample. The sample is clamped by the chuck 71. After clamping, the small motor 7 drives the chuck 71 to rotate to ensure the grinding effect on the sample.

[0032] In this technical solution, as Figures 1-3 shown, the water spray pipe 8 is provided with a bendable bamboo joint pipe section 81 and a telescopic pipe section 82 that can be telescoped. It is convenient to adjust the position of the water spray port. At the same time, in cooperation with the telescopic telescopic pipe section 82, it can also ensure that the water spray pipe 8 can maintain the water supply effect as the telescopic cylinder 6 expands and contracts.

[0033] In this technical solution, as Figures 1-3 shown, a plain bearing 51 is provided between the cantilever 5 and the column 4. The stability of the rotation of the cantilever 5 is improved. The plain bearing 51 can also be replaced by a rotating ring, etc., to provide a certain support for the cantilever 5, reduce the axial force on the driving motor, and ensure the stable operation of the driving motor. A counterweight 52 is provided on the side of the cantilever 5 away from the telescopic cylinder 6. By the counterweight 52, the weights on both sides are kept roughly evenly distributed, ensuring the stability of the rotation of the cantilever 5 and the accuracy of the movement of the sample.

[0034] In this technical solution, as Figures 1-3 shown, a supporting ring 13 for placing the grinding disc 2 and the pickling cup 3 is provided on the side wall of the water tank 1. The stability of the grinding disc 2 and the pickling cup 3 is improved, and it is also convenient for the installation and replacement of the grinding disc 2 and the pickling cup 3.

[0035] In this technical solution, as Figures 1-3 shown, a collecting hopper 11 is provided at the lower end of the water tank 1, and a sewage outlet 12 is opened at the lower end of the collecting hopper 11. The collecting hopper 11 collects the debris and the like flowing back during grinding and sends it out through the sewage outlet 12, which is convenient for the cleaning and maintenance of the device.

[0036] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
