Description

Technical Field

[0001] This invention belongs to the field of grinding technology, specifically an automatic grinding machine. Background Technology

[0002] An automatic rock grinding mill is a laboratory device used in geology, metallurgy, machinery, petroleum, coal, building materials, nuclear industry, and various universities for metallographic, rock and mineral identification, and paleontological specimen research. The rock grinding mill grinds rock samples into thin slices through grinding, so that the rock phase can be analyzed under a microscope after sampling. It includes two main functions: cutting and grinding. Cutting is used to cut the rock sample into the required shape, and grinding is used to grind the sample to a certain thickness to meet the needs of subsequent analysis.

[0003] Because different rock samples have different hardness, when grinding rocks, the grinding part is mainly flushed by the grinding fluid pipe to ensure the quality and speed of grinding. However, the grinding fluid is easy to remain at the bottom and come into contact with the grinding powder to form dirt. If it is not cleaned in time, it will affect the service life of the equipment. Therefore, an automatic grinding machine is needed. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: The automatic grinding machine of the present invention includes a base plate, a frame fixedly connected to the top of the base plate, a balance bracket fixedly connected to the top of the frame, a main machine drum rotatably connected to the bottom of the balance bracket, a mounting base fixedly connected to the top of the frame, a pressure sensor installed in the inner cavity of the mounting base, a controller installed at the center of the bottom end of the base plate, a clamping assembly installed on the top of the controller, the clamping assembly being used to clamp the petrographic workpiece, a housing fixedly connected to the top of the controller, a grinding fluid pipe fixedly connected to the inner side wall of the frame, and a drive assembly installed inside the mounting base, the drive assembly being used to drive the clamping assembly, facilitating the clamping assembly to clamp the petrographic workpiece.

[0007] Furthermore, the electric telescopic cylinder has a collar that is sleeved around the outer periphery of the electric push rod.

[0008] Furthermore, the top of the spring is fixedly connected to a pressure sensor, and a displacement sensor is installed on the outer periphery of the electric push rod.

[0009] Furthermore, the pressure bar is L-shaped and made of stainless steel.

[0010] Furthermore, the pressure block includes a cleaning component for cleaning the solution sprayed from the grinding fluid pipe into the housing. A slider is fixedly connected to the end of the middle rod. A receiving cavity is provided on one side of the housing. The slider is slidably connected to the receiving cavity. A storage tube is slidably connected to the bottom end of the slider. A through pipe is provided at the bottom end of the storage tube. An output component is fixedly connected to the inner side wall of the frame.

[0011] Furthermore, the receiving cavity is connected to the outer shell, the storage tube is made of rubber, and the storage tube contains a sodium hydroxide solution.

[0012] Furthermore, the controller includes a clamping assembly for pressing the petrographic workpiece. The clamping assembly includes a central column mounted on the top of the controller, a sleeve fixedly connected to the top of the central column, multiple intermediate clamping strips along the outer edge of the sleeve, two raised strips on the inner sidewall of each intermediate clamping strip, thin strips fixedly connected to the inner side of each intermediate clamping strip, multiple arc-shaped strips fixedly connected to the ends of the thin strips, a guide rail mounted on the inner sidewall of the intermediate clamping strip, the upper part of each arc-shaped strip slidably connected to the guide rail, and a wiping plate fixedly connected to the bottom end of each intermediate clamping strip. The wiping plate is used to agitate the moisture inside the outer shell and accelerate the fusion of sodium hydroxide solution and dirt. One of the raised strips is fixedly connected to a lower pressure strip.

[0013] Furthermore, the size of the wiping pad is adapted to the internal size of the outer shell, the arc-shaped strip is circular, and the interior of the arc-shaped strip has a central shape structure.

[0014] Furthermore, the inner wall of the middle card strip is provided with a card block located between two protruding strips, and the distance between the two protruding strips is adapted to the size of the card block.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The automatic grinding machine of the present invention uses a pressure block to drive a slider to move downwards. The slider moves downwards and squeezes the storage tube, squeezing out sodium hydroxide solution from inside the storage tube. The sodium hydroxide solution enters the outer shell through a pipe.

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] Combination Figures 1 to 3 As shown in the embodiment of the present invention, an automatic grinding machine includes a base plate 1, a frame 2 fixedly connected to the top of the base plate 1, a balance bracket 3 fixedly connected to the top of the frame 2, a main machine drum 6 rotatably connected to the bottom of the balance bracket 3, a mounting base 4 fixedly connected to the top of the frame 2, a pressure sensor 5 installed in the inner cavity of the mounting base 4, a controller 7 installed at the bottom center of the base plate 1, a clamping assembly installed on the top of the controller 7 for clamping the petrographic workpiece, a housing 8 fixedly connected to the top of the controller 7, a grinding fluid pipe 9 fixedly connected to the inner side wall of the frame 2, and a drive assembly installed inside the mounting base 4 for driving the clamping assembly to facilitate the clamping assembly in clamping the petrographic workpiece.

[0031] During operation, when performing grinding wheel processing, the petrographic workpiece to be ground is first placed in the clamping assembly, the controller 7 is started, and the main machine drum 6 gradually moves. After reaching a suitable grinding force, the main machine drum 6 completes the uniform grinding of the petrographic workpiece.

[0032] During the grinding process, a lot of powder and slag are generated after the petrographic workpiece is ground. Grinding fluid is sprayed out through the grinding fluid pipe 9 to wash it. Although the powder and slag can be cleaned, the powder and slag will flow down and cause dirt to the equipment. Therefore, the downward pressure generated by the movement of the drive component is used to squeeze the cleaning agent stored in the downward pressure path, so that the squeezed cleaning agent is discharged and the dirty part is finally removed.

[0033] like Figures 4 to 5 As shown, the drive assembly includes an electric push rod 41, a pressure block 42 fixedly connected to the bottom end of the electric push rod 41, a groove is provided 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 collar sleeved on the outer periphery of the electric push rod 41; the top of the spring 48 is fixedly connected to a pressure sensor 5, and a displacement sensor is installed on the outer periphery of the electric push rod 41.

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

[0035] like Figure 9As shown, the pressure block 42 includes a cleaning component, which is used to clean the solution sprayed from the grinding fluid pipe 9 into the housing 8. The cleaning component includes a central rod 431, with a slider 436 fixedly connected to the end of the central rod 431. A receiving cavity 432 is provided on one side of the housing 8, and the slider 436 is slidably connected to the receiving cavity 432. A storage tube 433 is slidably connected to the bottom end of the slider 436, and a through pipe 435 is provided at the bottom end of the storage tube 433. An output component 434 is fixedly connected to the inner side wall of the frame 2. The receiving cavity 432 is connected to the housing 8, and the storage tube 433 is made of rubber and contains a sodium hydroxide solution.

[0036] During operation, when it is necessary to clean the powder residue, using this embodiment of the invention, the pressure block 42 moves downward to drive the middle rod 431 to work. When the middle rod 431 moves downward, it is linked to the movement of the slider 436. The downward movement of the slider 436 squeezes the storage tube 433, squeezing out sodium hydroxide solution from inside the storage tube 433. The sodium hydroxide solution enters the outer shell 8 through the through pipe 435. The sodium hydroxide solution mixes with the dirt washed away by the grinding fluid, thereby cleaning the dirty part in the liquid and achieving the effect of timely cleaning of 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 for pressing the petrographic workpiece. The clamping assembly includes a central column 71 mounted on the top of the controller 7. A sleeve 70 is fixedly connected to the top of the central column 71. Two protruding strips 73 are fixedly connected to the outer edge of the sleeve 70. Multiple intermediate clamping strips 74 are provided on the outer surface of the protruding strips 73. Thin strips 75 are fixedly connected to the inner side of each intermediate clamping strip 74. Multiple arc-shaped strips 76 are fixedly connected to the ends of the thin strips 75. Guide rails 7 are installed on the inner wall of the intermediate clamping strips 74. 7. The upper part of the arc-shaped strip 76 is slidably connected to the guide rail 77. The bottom end of the middle locking strip 74 is fixedly connected to a wiping pad 78. The wiping pad 78 is used to rub against the inner wall of the outer shell 8 to facilitate cleaning of the inner wall of the outer shell 8. The lower pressure strip 49 is fixedly connected to a protruding strip 73. The wiping pad 78 contacts the inner wall of the outer shell 8. The arc-shaped strip 76 is arc-shaped. The inner side wall of the middle locking strip 74 is provided with a locking block located between the two protruding strips 73. The distance between the two protruding strips 73 is adapted to the size of the locking block.

[0038] During operation, the petrographic workpiece needs to be clamped before the automatic grinding disc is applied. In this embodiment of the invention, after the electric telescopic cylinder 47 is activated, the telescopic rod 46 is pushed out. The telescopic rod 46 drives the lower pressure bar 49 to move downward, and the lower pressure bar 49 drives the protruding bar 73 to move downward. The two protruding 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 tilted due to the influence of the clamping block. The end of the middle clamping bar 74 moves towards the central column 71. The middle clamping bar 74 squeezes towards the center to fix the petrographic workpiece, 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 plate 78 to move. The wiping plate 78 wipes the inner wall of the outer casing 8, which helps to improve the cleanliness of the inner wall of the outer casing 8.

[0040] At the same time, the middle clamping strip 74 tilts towards the central column 71, and the thin strip 75 tilts along with the middle clamping strip 74. The thin strip 75 drives the arc-shaped strip 76 to slide out from inside the guide rail 77. When it slides out, the inner diameter displacement performs secondary clamping on the protruding strip 73, thereby improving the clamping effect.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
