[0002] Automatic rock grinder is a laboratory equipment used for metallography, rock and mineral identification and paleontological specimen research in geology, metallurgy, machinery, petroleum, coal, building materials, nuclear engineering and various colleges and universities. The petrographic grinder grinds rock samples into thin slices by grinding, so as to analyze the petrography under a microscope after sampling. It includes two main functions: cutting and grinding. Cutting is used to cut rock samples into the required shape, and grinding is used to grind the samples to a certain thickness to meet the needs of subsequent analysis.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] When working, when performing grinding processing, first place the petrographic workpiece to be ground in the clamping assembly, start the controller 7, and the main machine drum 6 gradually runs. After having a force suitable for grinding, the main machine drum 6 completes the uniform grinding of the petrographic workpiece;

[0032] During the grinding process, a lot of powder residue will be formed after the petrographic workpiece is ground, and the grinding fluid is sprayed through the grinding fluid pipe 9 to flush it. Although the powder residue can be cleaned, the powder residue will flow downward after flushing and cause the equipment to be dirty. Therefore, the downward pressure generated by the movement of the driving component squeezes the cleaning agent stored in the downward pressure path, so that the squeezed cleaning agent is discharged, and finally the dirty part is removed.

[0033] like Figures 4 to 5 As shown, the driving assembly includes an electric push rod 41, a pressure block 42 is fixedly connected to the bottom end of the electric push rod 41, a groove is opened inside the pressure block 42, a telescopic rod 46 is inserted into the groove, an electric telescopic cylinder 47 is fixedly connected to the top of the telescopic rod 46, a spring 48 is fixedly connected to the top of the electric telescopic cylinder 47, and a lower pressure strip 49 is fixedly connected to the bottom end of the telescopic rod 46; the electric telescopic cylinder 47 has a ring sleeved on the outer periphery of the electric push rod 41; the top of the spring 48 is fixedly connected to the pressure sensor 5, and a displacement sensor is installed on the outer periphery of the electric push rod 41.

[0034] During operation, before the petrographic workpiece needs to be ground, the petrographic workpiece needs to be clamped using the embodiment of the present invention, and the electric telescopic cylinder 47 is started. The electric telescopic cylinder 47 pushes the telescopic rod 46 downward, and the telescopic rod 46 contacts the lower pressure bar 49. The lower pressure bar 49 moves downward, and the lower pressure bar 49 promotes the operation of the clamping assembly, causing the clamping assembly to deform toward the middle, thereby firmly clamping the petrographic workpiece in the middle.

[0035] like Fig. 9As shown, the pressing block 42 includes a cleaning component, which is used to clean the solution sprayed from the grinding liquid pipe 9 in the shell 8. The cleaning component includes a middle rod 431, and a slider 436 is fixedly connected to the end of the middle rod 431. A accommodating chamber 432 is provided on one side of the shell 8. The slider 436 is slidably connected to the accommodating chamber 432. The bottom end of the slider 436 is slidably connected to a storage tube 433. A through tube 435 is provided at the bottom end of the storage tube 433. An output member 434 is fixedly connected to the inner wall of the frame 2; the accommodating chamber 432 is connected to the shell 8, and the storage tube 433 is made of rubber material, and there is a sodium hydroxide solution in the storage tube 433.

[0036] During operation, when it is necessary to clean the powder residue, the embodiment of the present invention is used, the pressing block 42 drives the middle rod 431 downward to work, and when the middle rod 431 moves downward, the sliding block 436 moves in conjunction, and the sliding block 436 moves downward to squeeze the storage tube 433, and the sodium hydroxide solution is squeezed out of the storage tube 433, and the sodium hydroxide solution enters the outer shell 8 through the through pipe 435, and the sodium hydroxide solution is merged with the dirt flushed by the grinding fluid, so as to clean the dirty part in the liquid, thereby achieving the effect of timely cleaning the dirt; it should be noted that the sodium hydroxide solution will not affect the petrographic workpiece.

[0037] like Figures 6 to 8 As shown, the controller 7 includes a clamping assembly, which is used to squeeze the petrographic workpiece. The clamping assembly includes a central column 71 installed on the top of the controller 7. A sleeve 70 is fixedly connected to the top of the central column 71. Two raised strips 73 are fixedly connected to the outer edge of the sleeve 70. A plurality of middle clamping strips 74 are arranged on the outer surface of the raised strip 73. Thin strips 75 are fixedly connected to the inner side of the middle clamping strips 74. A plurality of arc strips 76 are fixedly connected to the ends of the thin strips 75. A guide rail 7 is installed on the inner wall of the middle clamping strip 74. 7. The upper part of the arc strip 76 is slidably connected to the guide rail 77, and the bottom end of the middle card strip 74 is fixedly connected with a wiping piece 78, which is used to rub against the inner wall of the shell 8 to facilitate cleaning the inner wall of the shell 8. The lower pressing strip 49 is fixedly connected with a raised strip 73; the wiping piece 78 contacts the inner wall of the shell 8, and the arc strip 76 is in an arc shape; the inner side wall of the middle card strip 74 is provided with a card block located between the two raised strips 73; the distance between the two raised strips 73 is adapted to the size of the card block.

[0038] During operation, the petrographic workpiece needs to be clamped before the automatic grinding disc is used. When the embodiment of the present invention is used, after the electric telescopic cylinder 47 is started, the telescopic rod 46 is pushed out, and the telescopic rod 46 drives the lower pressure bar 49 to move downward, and the lower pressure bar 49 drives the raised bar 73 to move downward, and the two raised bars 73 drive the clamping block to move downward. When the clamping block moves downward, the end and bottom of the middle clamping bar 74 are respectively affected by the clamping block and tilted, and the end of the middle clamping bar 74 moves toward the direction close to the center column 71, and the middle clamping bar 74 is squeezed toward the middle to fix the petrographic workpiece, thereby ensuring stability during grinding; it should be noted that the petrographic workpiece needs to be placed inside the sleeve 70 first;

[0039] When the bottom of the middle card strip 74 is tilted, the bottom of the middle card strip 74 will drive the wiping sheet 78 to move, and the wiping sheet 78 will wipe the inner wall of the shell 8, so as to improve the cleanliness of the inner wall of the shell 8.

[0040] At the same time, the middle clamping strip 74 tilts toward the center column 71, and the thin strip 75 will tilt along with the middle clamping strip 74. The thin strip 75 drives the arc strip 76 to slide out from the inside of the guide rail 77. When sliding out, the inner diameter displacement performs a second clamping on the raised strip 73, thereby improving the clamping effect.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
