One end of the top of the placement bottom plate is fixedly installed with a mounting frame. The top end inside the mounting frame is installed with a translation mechanism, and the bottom end of the translation mechanism is installed with a cutting mechanism.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model. Embodiment 1

[0027] The preferred embodiment of the core cutting and sample preparation equipment for engineering quality inspection provided by the present utility model is as follows Figures 1 to 5As shown: A core-cutting and sample-making device for engineering quality inspection, including a base 6; a clamping assembly 5 symmetrically assembled at the top of one side of the base 6, and the clamping assembly 5 is used for clamping and fixing the sample; a fixing frame 1 fixedly connected to the top of the base 6, and a controller 7 is fixedly connected to one side of the fixing frame 1; a moving assembly 2 assembled on the inner top wall of the fixing frame 1, and the moving assembly 2 is used to realize the horizontal adjustment of the cutting position; a hydraulic cylinder 11 arranged at the bottom end of the moving assembly 2, and the output end of the hydraulic cylinder 11 is fixedly connected to a mounting frame 3; a driving motor 4 fixedly connected to the lower end of one side of the mounting frame 3, the output end of the driving motor 4 penetrates through the mounting frame 3 and is fixedly connected to a rotating rod 12 through a coupling, and a cutting tool 10 is arranged on the surface of the rotating rod 12; a mounting assembly 9 assembled on the surface of the rotating rod 12, and the mounting assembly 9 is used to realize the disassembly, assembly and fixing of the cutting tool 10; a fixed-length assembly 8 assembled on the top of the other side of the base 6, and the fixed-length assembly 8 is used to realize the fixed-length cutting of the sample.

[0028] The fixed-length assembly 8 includes: a fixed slot 806 opened at the middle position of the top of the other side of the base 6; a fixed-length threaded rod 804 rotatably connected to the inner wall of the fixed slot 806, and a fixed-length threaded block 808 is threadedly connected to the surface of the fixed-length threaded rod 804; a fixed-length plate 802 fixedly connected to the top of the fixed-length threaded block 808; an indicating block 807 fixedly connected to one end of the fixed-length plate 802; a scale indicating bar 805 fixedly connected to the top of the other side of the base 6; a turning handle 803 rotatably connected to the other side of the base 6, and one end of the turning handle 803 is fixedly connected to one end of the fixed-length threaded rod 804.

[0029] It should be noted that there are still certain deficiencies in the existing core-cutting and sample-making devices for engineering quality inspection during the actual use process. When cutting cores and making samples, it is necessary for the staff to judge the length of the cut sample by themselves, and the visual judgment error is relatively large. If manual measurement is required every time, it will increase the labor intensity of the staff and reduce the corresponding core-cutting and sample-making work efficiency, resulting in inconvenience in its use.

[0030] In this embodiment, first adjust according to the length of the sample to be cut. At this time, rotate the turning handle 803 to drive the fixed-length threaded rod 804 to rotate. By using the threaded fit between the fixed-length threaded rod 804 and the fixed-length threaded block 808, the fixed-length threaded block 808 slides to drive the fixed-length plate 802 to slide. At the same time, the sliding of the fixed-length plate 802 will drive the indicating block 807 to slide. Then, in cooperation with the scale indicating strip 805, the distance between one side of the fixed-length plate 802 and one side of the fixed bracket 1 can be known, and this distance is made equal to the length of the sample to be cut. After that, during each cutting, one end of the sample is abutted against one side of the fixed-length plate 802, so as to fix the length of this section of the sample to be cut and achieve fixed-length cutting. Then, place the sample on the top of the base 6 and make one end of it directly abut against one side of the fixed-length plate 802. Then use the clamping assembly 5 to clamp and fix the sample. After that, start the hydraulic cylinder 11 to drive the mounting frame 3 to descend, and start the driving motor 4 to make the rotating rod 12 rotate to drive the cutting tool 10 to rotate, so as to cut the sample. At the same time, use the moving assembly 2 to make the cutting tool 10 slide horizontally, which is convenient for cutting samples with different side lengths. At the same time, when the cutting tool 10 needs to be maintained or replaced, use the mounting assembly 9 to quickly remove the cutting tool 10 from the surface of the rotating rod 12, improving the work efficiency of its maintenance or replacement.

[0031] In a further preferred embodiment of the present utility model, a sliding groove 801 is opened on the other side of the top of the base 6, and a slider 809 fixedly connected to the bottom end of the fixed-length plate 802 and slidably engaged with the inside of the sliding groove 801 is provided.

[0032] In this embodiment, by using the sliding of the slider 809 inside the sliding groove 801, the smoothness of the sliding of the fixed-length plate 802 is improved. Embodiment 2

[0034] In this embodiment, the mounting block 905 is moved to drive the sliding block 904 to slide inside the mounting groove 906 to compress the mounting spring 903 until it is completely separated from the mounting hole 902, and then the mounting plate 908 is pulled hard to be completely separated from the surface of the rotating rod 12, so that the cutting knife 10 can be removed from the surface of the rotating rod 12. When installing, the cutting knife 10 is sleeved on the surface of the rotating rod 12, and the T-shaped rotating rod 12 is used to limit the position of the cutting knife 10 after sliding installation, and then the mounting block 905 is moved to slide to a suitable position. After that, the mounting plate 908 is put on the surface of the rotating rod 12, and the clamping block 907 slides into the clamping groove 901 to increase the friction of the sliding sleeve of the mounting plate 908, and then the mounting block 905 is loosened, and the elastic force of the mounting spring 903 is utilized to make the sliding block 904 slide and drive the mounting block 905 to slide into the mounting hole 902, so as to realize the limited fixation of the mounting plate 908 after sliding, so as to make the cutting knife 10 firmly installed on the surface of the rotating rod 12, and realize the quick disassembly and assembly of the cutting knife 10.

[0038] In this embodiment, the convex block 907 and the slot 901 are used to improve the firmness and position accuracy of the sliding sleeve between the mounting plate 908 and the surface of the rotating rod 12, so as to facilitate the subsequent accurate engagement of the mounting block 905 with the inside of the mounting hole 902.
