[0031] It should be noted that: through the arrangement of the clamping disc 214 and the clamping plate 224 in the supporting assembly 2, in the subsequent use process, the end of the core sample can be clamped by the clamping disc 214, and the outer wall of the core sample can be clamped by the clamping plate 224. By clamping and fixing different areas of the core sample, the end and outer wall of the core sample can be staggered and clamped. When in use, the grinding disc 51 can smoothly grind the outer wall of the core sample, thereby improving the grinding range of the device.

[0032] In the embodiments of the present invention, please refer to Figures 1 to 5The top of the box body 1 is provided with a support assembly 3 for supporting the grinding motor 5. The support assembly 3 includes a support frame 31. The interior of the support frame 31 is provided with a rotatably connected driving screw 311. The outer wall of the driving screw 311 is sleeved with a threaded movable plate 312, and the inner wall of the movable plate 312 is slidably connected to the outer wall of the support rod in the support frame 31. A suspension cylinder 32 is fixedly installed on the top of the support frame 31, and the suspension cylinder 32 is fixedly installed on the inner top of the box body 1, and a motor for driving the driving screw 311 is fixedly installed on the side wall of the support frame 31. The movable plate A rotating motor 313 is fixedly installed at the bottom of 312, and a rotating frame 33 is rotatably installed outside the rotating motor 313 at the bottom of the movable plate 312. A fixedly connected adapter plate 331 is installed at the bottom of the rotating frame 33. The outer wall of the adapter plate 331 is fixedly connected to the grinding motor 5, and a fixedly connected grinding disc 51 is installed at the output end of the grinding motor 5. A fixedly connected suspended electric push rod 7 is provided on the outer wall of the adapter plate 331, and a fixedly connected adapter block 71 is installed at the output end of the suspended electric push rod 7, and a vertically and horizontally distributed rangefinder 72 is provided on the outer wall of the adapter plate 331.

[0033] It should be noted that: through the setting of the driving screw 311 and the suspension cylinder 32 in the support assembly 3, during use, when the two are working, the grinding motor 5 mounted on the support frame 31 can be moved horizontally and vertically, so that the grinding motor 5 can smoothly drive the grinding disc 51 to fully grind the outer wall of the core sample. When the grinding motor 5 is driven by the horizontally and vertically mounted rangefinder 72, the distance between the grinding disc 51 and the core sample can be measured by the rangefinder 72, and then the control box 12 can accurately control the moving distance of the grinding disc 51 by comparing the measured distance with the required grinding depth, so that the grinding depth of the grinding disc 51 can be more accurate.

[0034] In the embodiments of the present invention, please refer to Figures 1 to 5 A fixedly connected control box 12 is provided on the outer wall of the box body 1. One side wall of the box body 1 is an open structure, and a slot 11 is provided on the side wall of the opening of the box body 1. A slidingly connected baffle door 4 is inserted into the inside of the slot 11. A transparent plate 41 is inlaid inside the baffle door 4. Fixedly connected lifting electric push rods 42 are provided between both sides of the baffle door 4 and the box body 1.

[0035] It should be noted that: by inserting a baffle door 4 on the box body 1, the baffle door 4 can achieve sealing of the box body 1, thereby preventing the dust generated during the grinding process from being directly spread in the air and causing air pollution. In order to improve the dust treatment effect, a pipe can also be installed on the inner top of the box body 1 to connect the inside of the device with an external dust removal device, thereby realizing filtering and dust removal of the grinding dust.

[0036] In the embodiments of the present invention, please refer to Figures 1 to 5 A screw rod protection sleeve 6 is fixedly connected between both sides of the movable plate 312 and the support frame 31 , and the screw rod protection sleeve 6 is located outside the driving screw rod 311 .

[0037] It should be noted that: through the setting of the screw protection sleeve 6, during the later use process, the screw protection sleeve 6 can protect the outer wall of the driving screw 311, thereby preventing dust from being scattered on the driving screw 311 during the grinding process and affecting the operation of the driving screw 311.

[0038] The working principle of the core sample grinding structure provided by the utility model is as follows:

[0039] When using the device, the staff can first move the core sample between the clamping plates 214 on both sides as needed, and then control the horizontal cylinder 211 to drive the clamping plates 214 on both sides to move relative to each other until the outer wall of the clamping plate 214 abuts against the end of the core sample, thereby completing the clamping and fixing of the core sample.

[0040] At this time, the staff can control the vertical distance meter 72 to work, so as to detect the distance between the grinding disc 51 and the outer wall of the core sample in the initial state. At this time, the staff can input the setting on the control box 12 according to the required grinding depth;

[0041] After the setting is completed, the driving screw 311, the suspension cylinder 32 and the grinding motor 5 can be controlled to work. The working suspension cylinder 32 will drive the grinding motor 5 below to move in the vertical direction, so that the grinding disc 51 can be moved to the grinding depth position required for the core sample, and the working driving screw 311 can drive the grinding motor 5 below to move in the horizontal direction through the threaded structure. When the outer wall of the grinding disc 51 is against the outer wall of the core sample, the outer wall of the core sample can be polished.

[0042] During this process, the rotating motor 213 can be controlled to work, and the working rotating motor 213 can drive the core sample clamped at the end to rotate, so that the grinding disc 51 can fully grind the outer wall of the core sample;

[0043] After the outer wall of the core sample is polished, the vertical cylinder 221 can also be controlled to work. The working vertical cylinder 221 will drive the top supporting plate 226 to move upward through the mounting plate 222. When the top of the supporting plate 226 is against the outer wall of the core sample, its squeezing force can act on the pressure sensor 225 below. At this time, the control box 12 can monitor and control the clamping cylinders 223 on both sides to work by monitoring the pressure sensor 225. The working clamping cylinder 223 can drive the clamping plate 224 at the end to move. When the outer wall of the clamping plate 224 is against the outer wall of the core sample, the horizontal cylinder 211 can be controlled to contract so that the clamping plate 214 is against the end of the core sample, thereby clamping and fixing the core sample through the abutment between the clamping plate 224 and the outer wall of the core sample.

[0044] Then the suspension cylinder 32 can be controlled to work so that the grinding disc 51 below it moves to the end of the core sample. Then the distance from the grinding disc 51 to the end of the core sample can be detected by the horizontally mounted rangefinder 72, and the above steps can be repeated to achieve the end of the core sample, so that the device can smoothly perform comprehensive grinding on the outer wall of the core sample, thereby improving the user experience of the device.

[0045] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0046] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
