[0001] This utility model relates to the technical field of core cutting and sample preparation tools, and in particular to a core cutting and sample preparation device for engineering quality testing. Background Technology
[0002] In engineering quality testing, core cutting and sample preparation is a crucial step in obtaining test samples. The safety of the equipment and the cleanliness of the operating environment directly affect the efficiency of the testing work and the health of the operators. However, traditional core cutting and sample preparation equipment for engineering quality testing has significant defects in the cutting operation.
[0003] Traditional cutting operations are mostly carried out in open environments, lacking a dedicated enclosed structure. When the saw blade rotates at high speed to cut samples, it generates a large amount of debris and dust. This debris and dust fly uncontrollably in all directions, not only polluting the operating environment and causing the workbench and surrounding area to become messy, increasing the difficulty of subsequent cleaning, but also potentially causing accidental injuries to the operator's eyes and skin, posing a significant safety hazard. Therefore, the above problems need to be addressed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example: See Figure 1-4 This utility model discloses a core-cutting sample preparation device for engineering quality testing, comprising a worktable 1. A first motor 7 is installed on one side of the worktable 1, which facilitates the movement of a mounting plate 3 and a three-jaw chuck along the worktable 1. The first motor 7 has a stable rotation speed, ensuring the smooth movement and positional accuracy of the mounting plate 3. The mounting plate 3 is movably mounted on the worktable 1, which facilitates the movement of the three-jaw chuck along the worktable 1 to adjust the position of the sample to be cut. The three-jaw chuck is mounted on the mounting plate 3, and a second motor 8 is installed on the other side of the mounting plate 3 to drive the three-jaw chuck. The three-jaw chuck is designed to rotate, allowing the sample held in the chuck to rotate accordingly. This facilitates adjustment of the sample cutting angle, enabling multi-directional cutting and improving sample preparation flexibility. A processing box 4 is fixedly attached to one side of the top of the worktable 1. The processing box 4 provides a closed operating space for sample cutting, preventing debris from splashing during the cutting process and protecting the operator's safety. At the same time, the slotted plate 12 allows debris to fall into the collection drawer 5 for easy cleaning. A clamping assembly is provided on one side of the processing box 4, and a bracket 2 is fixedly attached to the outside of the processing box 4. A connecting plate is hinged to the bracket 2, and a cutting component is provided on the connecting plate.
[0020] In this invention, a sealed door is symmetrically hinged to the other side of the processing box 4. A perforated plate 12 is fixedly connected to the bottom of the processing box 4. The perforated plate 12 allows the cutting debris to fall into the collection drawer 5 through the holes of the perforated plate 12, thus separating the sample support from the debris and facilitating the collection of the debris. A sliding groove is provided on the other side of the workbench 1. A collection drawer 5 for collecting items falling from the perforated plate 12 is slidably provided in the sliding groove. The collection drawer 5 facilitates the collection of debris generated during the cutting process, preventing debris from scattering onto the workbench 1 and the surrounding environment, facilitating subsequent unified cleaning and maintaining a clean working environment. The clamping assembly includes a mounting block located on one side of the bottom of the processing box 4 and a bidirectional lead screw located on the mounting block. A fourth motor 13 is mounted on one side of the mounting block. The output end of the fourth motor 13 is coaxially fixed to the bidirectional lead screw. Moving blocks are symmetrically provided on the bidirectional lead screw. Fixed blocks are provided on the moving blocks. Two slots are provided at one end of the fixed blocks. One end of the fixed blocks passes through the slots. A clamping plate 14 is snapped in place. The inner wall of the clamping plate 14 is arc-shaped. A baffle 9 is fixedly attached to one side of the fixing block. The baffle 9 movably abuts against the side wall of the processing box 4. The clamping assembly facilitates the stable clamping of the sample, preventing the sample from shaking during the cutting process and ensuring cutting accuracy. At the same time, the snap-fit structure facilitates the replacement of the clamping plate 14 to adapt to samples of different sizes. The cutting component includes an electric push rod 6 mounted on the connecting plate. The output end of the electric push rod 6 is equipped with a cutter. One end of the cutter is equipped with a saw blade 10, and the other end of the cutter is equipped with a third motor 11. The electric push rod 6 facilitates precise control of the cutting depth, allowing the saw blade 10 to cut the sample according to the requirements and ensuring the accuracy of the cutting dimensions. An installation groove is opened in the worktable 1. A first lead screw is installed in the installation groove. The first lead screw is coaxially fixed to the output end of the first motor 7. The installation plate 3 is threadedly connected to the first lead screw. The first lead screw facilitates the movement of the installation plate 3 and the three-jaw chuck along the worktable 1.
[0021] Working Principle: When using this utility model, firstly, connect each electrical component in this application to the power supply. Then, place the sample to be tested on the three-jaw chuck and start the second motor 8. The second motor 8 drives the three-jaw chuck to tighten, initially fixing the sample. Subsequently, the first motor 7 starts, and its output end drives the first lead screw to rotate. The mounting plate 3, which is threaded to the first lead screw, is guided by the sliding structure of the worktable 1, driving the three-jaw chuck and the sample to move towards the processing box 4 until the sample enters the cutting area inside the processing box 4. At this time, the clamping assembly on one side of the processing box 4 starts working. The fourth motor 13 starts, driving the bidirectional lead screw to rotate, causing the moving blocks symmetrically arranged on the bidirectional lead screw to drive the fixed block and the clamping plate 14 to move closer to each other. Since the inner wall of the clamping plate 14 is arc-shaped, it can closely fit the sample surface, further firmly clamping the sample and preventing shaking during the cutting process. At the same time, the baffle 9 on one side of the fixed block abuts against the side wall of the processing box 4, limiting and stabilizing the clamping assembly. After the sample is fixed, the position of the cutting component is adjusted. The connecting plate on the bracket 2 can be adjusted at an angle through a hinge structure so that the cutter is aligned with the part of the sample to be cut. The third motor 11 is started, which drives the saw blade 10 to rotate at high speed. At the same time, the electric push rod 6 extends, pushing the cutter toward the sample. The saw blade 10 contacts the sample and cuts it. The debris generated during the cutting process falls into the collection tray 5 below through the sluice plate 12 at the bottom of the processing box 4, achieving centralized collection of debris. Finally, if it is necessary to adjust the cutting angle of the sample, the second motor 8 drives the three-jaw chuck to rotate, driving the sample to rotate to a suitable angle and then fixing it for cutting again. After the cutting is completed, the electric push rod 6 retracts, driving the cutter to reset. The fourth motor 13 reverses to release the clamping plate 14. The first motor 7 drives the mounting plate 3 to remove the sample from the processing box 4. Finally, the three-jaw chuck is opened to remove the sample, completing the entire core cutting sample preparation process. The use of the core cutting sample preparation equipment for engineering quality testing is now complete.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
