Technical Field
[0001] This utility model relates to the field of laboratory auxiliary equipment, specifically to a polishing device for rod-shaped samples. Background Technology
[0002] In the laboratory, rigorous grinding and polishing processes are often required for bar samples such as steel or copper rods to ensure the accuracy of the experimental structure.
[0003] Currently, grinding and polishing are usually done manually, which is time-consuming, labor-intensive, and has poor precision, directly affecting the test results and, in severe cases, even shortening the lifespan of rod samples.
[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] This invention relates to a polishing device for rod-shaped samples, comprising a connecting rod, a flexible adjustment section, and a connecting member. The connecting rod connects the flexible adjustment section and an electric stirrer, transmitting the rotational power of the electric stirrer to the flexible adjustment section. The flexible adjustment section can be bent within a certain angle, facilitating adjustment of the polishing angle of the rod-shaped sample and thus enabling more precise polishing. One end of the connecting member is connected to the flexible adjustment section, and the other end is connected to the connecting member, transmitting the rotational power of the electric stirrer to the rod-shaped sample, thereby facilitating polishing. Through this design, this invention provides a polishing device for rod-shaped samples that effectively transmits the rotational power of the electric stirrer to the rod-shaped sample, saving manpower and improving polishing efficiency. Simultaneously, the flexible adjustment section's bendability allows for adjustment of the polishing angle of the rod-shaped sample, achieving more precise polishing and ensuring optimal experimental results.
[0007] Furthermore, the flexible adjustment section is a spring.
[0008] Furthermore, the flexible adjustment section is a flexible shaft.
[0009] Furthermore, the connecting rod, the flexible adjusting section, and the connecting member are fixedly connected by a welding structure.
[0010] Furthermore, sleeves are provided at both ends of the flexible adjustment section, and fixing holes are provided on the sleeves; mounting holes matching the fixing holes are provided on the connecting rod and the connecting member, and pins are arranged in the mounting holes.
[0011] Furthermore, the pin is a square shaft, and the fixing hole and the mounting hole are matched with the pin.
[0012] In summary, compared with the prior art, this utility model has the following beneficial effects:
[0013] The connecting rod is used to connect the flexible adjustment section and the electric stirrer, and can transmit the rotational power of the electric stirrer to the flexible adjustment section. The flexible adjustment section can be bent within a certain angle, which makes it easy to adjust the grinding angle of the rod sample, and thus facilitates more precise grinding and polishing of the rod sample. One end of the connector is connected to the flexible adjustment section and the other end is connected to the connector, which transmits the rotational power of the electric stirrer to the rod sample, thus facilitating the grinding and polishing of the rod sample.

[0020] To improve or solve the technical problems of time-consuming, labor-intensive, and inaccurate manual grinding and polishing in the prior art, this utility model provides a grinding and polishing device for rod-shaped samples. The grinding and polishing device includes: a connecting rod 1, suitable for connection to an electric stirrer; a flexible adjustment section 2, one end of which is sleeved on the circumferential outer side of the connecting rod 1 and fixedly connected to the connecting rod 1; and a connecting piece 3, one end of which is fixedly connected to the flexible adjustment section 2, and the other end of which has a threaded hole 4 suitable for mating with rod-shaped samples.
[0021] Figure 1 This is a schematic diagram of an embodiment of the present invention for grinding and polishing rod-shaped samples. Figure 1 As shown, in one or more embodiments, the present invention provides a polishing tool for rod-shaped samples, comprising a connecting rod 1, a flexible adjustment section 2, and a connector 3.
[0022] See also Figure 1 The connecting rod 1 is adapted to be connected to an electric mixer. In one or more embodiments, the connecting rod 1 is generally cylindrical and has the same diameter as the mixing rod of the electric mixer. The end of the electric mixer may be a three-jaw chuck end, thereby allowing the connecting rod 1 to replace the mixing rod and be fixed to the electric mixer.
[0023] See also Figure 1The flexible adjustment section 2 is connected to the connecting rod 1 and the connecting member 3 at both ends, respectively, to transmit the rotational power of the electric stirrer to the rod sample. In one or more embodiments, the flexible adjustment section 2 is a spring. Specifically, the inner diameter of the flexible adjustment section 2 is the same as the outer diameter of the connecting rod 1, so that one end of the flexible adjustment section 2 can be sleeved on the circumferential outer side of the connecting rod 1. Further, the flexible adjustment section 2 is fixedly connected to the connecting rod 1 by a welding structure. Alternatively, a sleeve can be provided at the end of the flexible adjustment section 2, and a fixing hole can be provided on the sleeve. An installation hole is provided on the connecting rod 1, and a pin is provided in the installation hole. The pin is inserted into the installation hole and the fixing hole, thereby connecting the flexible adjustment section 2 and the connecting rod 1. Specifically, the pin is a square shaft, and the fixing hole and the installation hole are square holes, thereby preventing the flexible adjustment section 2 and the connecting rod 1 from rotating relative to each other. Limit blocks are provided at both ends of the pin, thereby preventing the pin from coming out. Further, the other end of the flexible adjustment section 2 is fixedly connected to the connecting member 3 by a welding structure. Alternatively, a sleeve can be provided at one end of the flexible adjustment section 2 near the connector 3, with the same connection structure as that between the connecting rod 1 and the flexible adjustment section 2. In another embodiment, the flexible adjustment section 2 is a flexible shaft.
[0024] See also Figure 1 The two ends of the connector 3 are connected to the flexible adjustment section 2 and the rod-shaped sample, respectively. In one or more embodiments, one end of the connector 3 is fixedly connected to the flexible adjustment section 2 by welding, and the other end has a threaded hole 4. It is understood that the rod-shaped sample is roughly cylindrical, and a threaded rod is formed at one end of the rod-shaped sample. The threaded rod matches the threaded hole 4, thereby realizing the connection between the rod-shaped sample and the connector 3.
[0025] This utility model is a grinding and polishing device for rod-shaped samples. In use, the electric stirrer clamps the connecting rod 1, the connecting piece 3 is screwed tightly to the rod-shaped sample, the electric stirrer is started, the rotation speed is adjusted, and the rod-shaped sample is wrapped with sandpaper for grinding and polishing. The angle can be adjusted through the flexible adjustment section 2. The structure is simple, made of common materials, and easy to manufacture and install.
[0026] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the protection scope of this utility model.
