Description

Technical Field

[0001] This utility model relates to the technical field of metallographic structure detection, and in particular to a dustproof component for rapid metallographic structure detection. Background Technology

[0002] A metallurgical microscope is an optical microscope used to observe the microstructure of metals and other materials. By magnifying and illuminating samples, it enables researchers to analyze the internal structure of materials, such as grains, phase distribution, and defects, in order to evaluate their mechanical properties, chemical composition, and processing quality. Metallurgical microscopes are widely used in materials science, metallurgy, mechanical engineering, and other fields, and play an important role, especially in metal failure analysis, welding quality inspection, and materials development. With the increasing number of materials being tested, the functional requirements for metallurgical microscopes are also increasing. Therefore, a dustproof component for rapid metallographic structure detection is particularly needed.

[0003] However, existing dustproof components for rapid metallographic analysis, although they achieve dustproofing through simple parts assembly and the opening and closing of the dust cover, rely heavily on springs during use or idle periods. This leads to significant wear on multiple sets of springs, thus affecting the lifespan of the device.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN217542843U that discloses a dustproof assembly for rapid metallographic analysis. The patent describes a "transparent dustproof cover movably fitted onto the surface of a column. This cover can slide down to the top of the testing stage, thus protecting the test sample and objective lens on the top of the stage from dust. The column is fixed to the top of the testing stage, which is in turn fixed to the top of the base for placing the test sample. An objective lens is located inside the column for observing the test sample. The bottom dimension of the transparent dustproof cover is related to the dimensions of the test sample." Corresponding to the platform, a movable transparent dustproof cover is installed between the column and the testing platform. This cover effectively protects the objective lens and the test sample from dust during rapid metallographic analysis, preventing external dust from entering the testing area and ensuring the accuracy of the metallographic results. While the above mechanism uses simple parts and the dustproof cover to achieve dust protection, it relies heavily on springs during use and downtime, leading to significant wear on multiple springs and affecting the device's lifespan.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a dustproof component for rapid metallographic structure detection, including a base 1 and a moving mechanism 2, wherein the moving mechanism 2 is provided on one side of the surface of the base 1;

[0027] The moving mechanism 2 includes a first slide groove 201, a second slide groove 202, a mounting groove 203, a recess 204, a positioning rod 205, a threaded rod 206, a damping spring 207, a bevel gear set 208, a first integrated sleeve 209, a second integrated sleeve 210, a damping ball 211, a motor 212, a protective cover 213, a slide rod 214, and an objective lens 215. The first slide groove 201 is formed on one side of the surface of the moving mechanism 2, and the second slide groove 202 is formed on one side of the moving mechanism 2. A mounting groove 203 is formed at one end of the first slide groove 201, and recesses 204 are formed on both sides of the first slide groove 201. A positioning rod 205 is fixedly connected inside the mounting groove 203. A threaded rod 206 is fitted inside the mounting groove 203. A damping spring 207 is connected to one end of the groove 204. A bevel gear set 208 is fixedly connected to one end of the threaded rod 206. A first integrated sleeve 209 is threadedly connected to the surface of the threaded rod 206. A second integrated sleeve 210 is threadedly connected to the surface of the threaded rod 206. A damping ball 211 is connected to the other side of the damping spring 207. A motor 212 is connected to one side of the bevel gear set 208. A protective cover 213 is fixedly connected to one side of the surface of the first integrated sleeve 209. The surface of the second integrated sleeve 210... A slide rod 214 is fixedly connected to one side, and an objective lens 215 is fitted onto the surface of the slide rod 214. Through the arrangement of a first slide groove 201, a second slide groove 202, a mounting groove 203, a recess 204, a positioning rod 205, a threaded rod 206, a damping spring 207, a bevel gear set 208, a first integrated sleeve 209, a second integrated sleeve 210, a damping ball 211, a motor 212, a protective cover 213, the slide rod 214, and the objective lens 215, in use, the motor 212 is first started. The motor 212 drives the bevel gear set 208 to rotate, and the rotation of the bevel gear set 208 causes the threaded rod 206 to rotate synchronously. The first integrated sleeve 209 and the second integrated sleeve 210, which are connected by threads, move axially along the threaded rod 206, thereby causing the protective cover 213 and the objective lens 215 to move synchronously. At the same time, the movement of the first integrated sleeve 209 and the second integrated sleeve 210 will press the damping ball 211. The damping ball 211 provides resistance to movement through the damping spring 207 to ensure the normal sliding of the components. Meanwhile, the positioning rods 205 are fitted on both sides of the integrated sleeve, which will provide double protection and increase the stability during operation. Finally, the sliding of the objective lens 215 on the slide rod 214 allows the device to observe slices at different positions.

[0028] Furthermore, the positions of the first slide 201 and the second slide 202 are aligned, and the dimensions of the first slide 201 and the second slide 202 match. One side of the first slide 201 extends through the second slide 202. Through the arrangement of the first slide 201 and the second slide 202, the first slide 201 and the second slide 202 are arranged opposite to each other and connected to form a stable guide channel. The first integrated sleeve 209 and the second integrated sleeve 210 installed therein can slide smoothly along the direction of the slide without easily deviating, thereby ensuring the smooth and precise movement of the protective cover 213 and the objective lens 215.

[0029] Furthermore, a positioning rod 205 is also fixedly connected to one end of the second slide groove 202. Two sets of positioning rods 205 are provided inside the first slide groove 201 and the second slide groove 202, and are arranged on both sides of the threaded rod 206. By setting the positioning rods 205, the positioning rods 205 are installed inside the first slide groove 201 and the second slide groove 202. Two sets are arranged on both sides of the threaded rod 206, which can effectively fix the position of the components inside the slide groove, ensure that they move along the predetermined track, and prevent the first integrated sleeve 209 and the second integrated sleeve 210 from shaking or deviating during the sliding process, thereby improving the stability and movement accuracy of the entire mechanism.

[0030] Furthermore, the interior of the second slide groove 202 is also provided with grooves 204. The grooves 204 are evenly distributed inside the first slide groove 201 and the second slide groove 202. By setting the grooves 204 on both sides of the first slide groove 201 and the second slide groove 202, a guide structure is formed, which allows the damping ball 211 to slide smoothly in the groove 204 and restricts its movement direction. Through the guidance of the groove 204, the damping ball 211 and other components inside the slide groove can always move in the predetermined trajectory, ensuring smooth linear motion.

[0031] Furthermore, the size of the damping ball 211 matches that of the groove 204. The damping ball 211 and the groove 204 form a sliding structure through the damping spring 207. Through the setting of the damping spring 207 and the damping ball 211, the damping ball 211 and the damping spring 207 together form a shock absorption system, which is embedded in the groove 204. When the moving mechanism 2 slides in the groove, the damping spring 207 presses the damping ball 211 into the groove 204 through elastic action, thereby providing buffering when encountering vibration or impact. This function can effectively reduce the impact of vibration on the moving accuracy, making the movement of the protective cover 213 and the objective lens 215 more stable. At the same time, the damping ball 211 is embedded in the groove 204 and can form resistance at different positions of the groove, helping the integrated sleeve to stabilize at a specific position. In this way, when the threaded rod 206 drives the integrated sleeve to slide to the designated position, the damping ball 211 can play a temporary positioning role, ensuring that the protective cover 213 and the objective lens 215 can stay in the accurate position, thereby meeting the requirements of precise positioning.

[0032] Furthermore, a set of threaded rods 206 is provided inside the first slide groove 201 and the second slide groove 202, and the two sets of threaded rods 206 are connected to each other. Through the setting of the threaded rods 206, the threaded rods 206 are connected to the motor 212 and the bevel gear set 208, converting the rotational power of the motor 212 into linear movement. The threaded rods 206 are threadedly connected to the first integrated sleeve 209 and the second integrated sleeve 210. When the threaded rods 206 rotate, they drive the integrated sleeves to move smoothly along the slide groove direction, thereby realizing the precise positioning and movement of the protective cover 213 and the objective lens 215. At the same time, the pitch of the threaded rods 206 determines the linear displacement corresponding to each rotation, so that the entire movement process has high-precision control capability. By adjusting the rotation angle or speed of the motor 212, the micro-step movement of the integrated sleeve and the objective lens 215 can be realized to meet the application requiring high positioning accuracy.

[0033] Furthermore, the first integrated sleeve 209 and the second integrated sleeve 210 are respectively fitted inside the first slide groove 201 and the second slide groove 202. The first integrated sleeve 209 and the second integrated sleeve 210 are in contact with the damping ball 211. The first integrated sleeve 209 and the second integrated sleeve 210 form a sliding structure with the threaded rod 206 through the bevel gear set 208 and the motor 212. Through the arrangement of the first integrated sleeve 209 and the second integrated sleeve 210, the first integrated sleeve 209 and the second integrated sleeve 210 are respectively connected to the protective cover 213 and the slide rod 214. The protective cover 213 cooperates with the objective lens 215. In this way, the integrated sleeve, as the core component of the objective lens 215 support structure, provides stable support force and ensures that the protective cover 213 and the objective lens 215 maintain balance and stability during movement.

[0034] Furthermore, the bevel gear set 208 is fitted inside the mounting groove 203, and the main body of the motor 212 is mounted on the base 1. One side of the motor 212 is fitted inside the mounting groove 203. The mounting groove 203 is located at one end of the first sliding groove 201 and is used to embed and fix the bevel gear set 208. Through the fixing effect of the mounting groove 203, the bevel gear set 208 remains stable during rotation and will not be displaced or loosened, thereby ensuring that the threaded rod 206 can be driven stably. One side of the motor 212 is also fitted inside the mounting groove 203. By stably positioning the motor 212 and the bevel gear set 208 in a specific position, the mounting groove 203 enables the rotational power of the motor 212 to be accurately transmitted to the bevel gear set 208, and then transmitted to the threaded rod 206 through the bevel gear set 208, thus achieving smooth power transmission.

[0035] Furthermore, two sets of slide rods 214 are provided. The slide rods 214 and the objective lens 215 form a mutual sliding structure. Through the setting of the slide rods 214, the slide rods 214 provide a stable support structure for the objective lens 215 by embedding the objective lens 215. At the same time, they provide guidance for the movement of the objective lens 215 in the sliding groove. The slide rods 214 ensure that the objective lens 215 slides smoothly along the specified direction when moving, and prevents the objective lens 215 from tilting or shifting.

[0036] Furthermore, the objective lens 215 is positioned above the protective cover 213. The protective cover 213 and the objective lens 215 move synchronously through the first integrated sleeve 209 and the second integrated sleeve 210. With the protective cover 213 positioned below the objective lens 215, it provides physical protection for the objective lens 215, preventing dust, dirt, or other external impurities from entering, keeping the objective lens 215 clean, and avoiding affecting the observation or imaging effect. At the same time, the protective cover 213 can effectively protect the objective lens 215 from external collisions or scratches, extending the service life of the objective lens 215.

[0037] Working principle: First, start the motor 212, which drives the bevel gear set 208 to rotate. The rotation of the bevel gear set 208 causes the threaded rod 206 to rotate synchronously, which in turn drives the first integrated sleeve 209 and the second integrated sleeve 210 connected to it to move axially along the threaded rod 206. This in turn drives the protective cover 213 and the objective lens 215 to move synchronously. At the same time, the movement of the first integrated sleeve 209 and the second integrated sleeve 210 will press the damping ball 211. The damping ball 211 provides resistance to movement through the damping spring 207, ensuring the normal sliding of the components. Meanwhile, the positioning rods 205 are embedded on both sides of the integrated sleeve, which provide double protection and increase the stability during operation. Finally, the sliding of the objective lens 215 on the slide rod 214 allows the device to observe slices at different positions.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
