Description

Technical Field

[0001] The utility model relates to the technical field of hardness testers, in particular to an easy-to-clean hardness tester provided with a limit buckle mechanism. Background Art

[0002] A hardness tester is an instrument for measuring the hardness of materials. The hardness measurement of metal materials was first proposed by Leomure. It indicates the ability of a material to resist hard objects pressing into the surface of the material. Hardness is one of the important performance data of metal materials. Generally, the higher the hardness, the better the wear resistance. During use, the material to be tested needs to be placed on the stage, and then the stage is moved by the drive mechanism to make the material contact with the indenter to measure the hardness of the material. However, in the actual measurement process, the material to be tested is placed directly on the stage, and the material to be tested is prone to movement, which leads to deviations in the measurement data. Utility Model Content

[0003] The purpose of the present invention is to provide an easy-to-clean hardness tester with a limit locking mechanism to solve the problem in the background art that the material to be tested is easily displaced when placed on a stage for measurement, resulting in inaccurate data.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an easy-to-clean hardness tester provided with a limiting snap-fit ​​mechanism, comprising a machine body, the machine body being C-shaped, and a brush being inserted into the side surface of the machine body, and the outer surface of the brush being in contact with the outer surface of the machine body, a lifting platform being slidably mounted on the outer surface of the machine body, the end of the machine body close to the lifting platform being inclined, a display and control device being provided on the inclined surface of the machine body, a cylinder being provided at the center of the lifting platform, and the cylinder of the lifting platform being in contact with a measuring head, the outer surface of the lifting platform being in contact with the measuring head, and the measuring head and the lifting platform being concentrically designed, a rotating sliding mechanism being provided at the end of the machine body away from the lifting platform, the material can be clamped and fixed by the rotating sliding mechanism, so that the material to be measured will not move around and cause measurement deviation.

[0005] Preferably, the rotating and sliding mechanism includes: a worm, which is rotatably installed inside the machine body, and a screw is rotatably installed inside the machine body, and the thread directions of the two ends of the screw are opposite, a worm wheel is fixedly installed on the outer surface of one end of the screw, and the worm wheel is meshed with the worm, a splint is slidably installed inside the machine body, and the outer surface of the splint is penetrated by the screw, and the screw and the splint are threadedly connected, and a handle is fixedly installed on one end of the worm located outside the machine body.

[0006] By adopting the above technical solution, the worm can be rotated to rotate the worm wheel meshing with the worm, and the rotation of the worm wheel drives the screw to rotate together. Due to the different directions of the threads on both sides of the screw, the splint can move closer to the center to clamp the material to be tested. The self-locking property of the worm wheel and the screw prevents the splint from loosening after clamping the material, so that the material will not move during testing and cause inaccurate data.

[0007] Preferably, a threaded rod with a handle is rotatably installed inside the machine body, and the handle of the threaded rod with a handle is different in shape from the handle of the worm, a sliding top block is slidably installed inside the machine body, and the sliding top block is threadedly connected to the threaded rod with a handle, the outer surface of the machine body is provided with scale lines, and the scale lines are aligned with the side surface of the sliding top block, and the sliding top block is L-shaped.

[0008] By adopting the above technical solution, the functions of the worm and the handle of the threaded rod with a handle are distinguished by their different shapes, so that people can distinguish them by touch, and the sliding top block can be displaced by rotating the threaded rod with a handle. By observing the movement of the sliding top block and the scale line, the measured material can be moved accurately to accurately obtain hardness data at different distances.

[0009] Preferably, a receiving sliding mechanism is provided on the outer surface of one end of the machine body close to the lifting platform, which can catch the dust and impurities dropped by the material during measurement, so that the dust and impurities will not fall into the inside of the screw and the outer surface of the lifting platform.

[0010] By adopting the above technical solution, by arranging the screw and the threaded rod with a handle above the machine body, dust and impurities on the material will not fall into the inside of the rotating clamping mechanism during measurement, thereby improving the service life of the rotating sliding mechanism.

[0011] Preferably, the receiving sliding mechanism includes: a receiving tray, the receiving tray is slidably mounted on the side surface of the machine body, and an elastic latch is slidably mounted on the side surface of one end of the machine body, a through hole is opened on the outer surface of the receiving tray, and the through hole of the receiving tray is concentric with the measuring head, a groove is provided on one end of the receiving tray away from the elastic latch, and the receiving tray is tilted

[0012] By adopting the above technical solution, impurities and dust falling from the outer surface of the material during measurement can be received through the receiving tray, reducing the amount of dust and impurities falling on the outer surface of the lifting platform and the measuring head, and the receiving tray can be easily inserted into the interior of the machine body and automatically fixed, so that the measuring head will not contact the receiving tray when it rises.

[0013] Preferably, the outer surface of the clamping plate is provided with a snap-fitting and plug-in mechanism, through which parts can be removed for replacement and the object to be tested will not fall off.

[0014] By adopting the above technical solution, chucks of different specifications and styles can be easily replaced, and the chuck can be disassembled for replacement or cleaning.

[0015] Preferably, the snap-fitting mechanism includes: a chuck, which is L-shaped and inserted into the outer surface of the splint, an elastic snap-fit ​​plate fixedly installed on the side surface of the chuck, a rotating pin installed through the side surfaces of the chuck and the splint, and the outer surface of the rotating pin fits with the outer surface of the chuck and the splint, the rotating pin is engaged with the elastic snap-fit ​​plate, and the elastic snap-fit ​​plate is of flexible design.

[0016] By adopting the above technical solution, the chuck can be inserted into the interior of the splint, and then the rotating pin can be vertically inserted into the interior of the splint and the chuck, and then rotated so that the rotating pin can engage with the elastic snap plate. The flexible design of the elastic snap plate enables the rotating pin to rotate through, and the L-shaped design of the chuck and the sliding top block can prevent the material from falling after the chuck is loosened.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the easy-to-clean hardness tester provided with a limit snap mechanism:

[0018] 1. Rotating the worm can drive the worm wheel to rotate, and the rotation of the worm wheel drives the screw to rotate together. As the screw rotates, the clamping plates on both sides move closer to the center or move to the sides, allowing the clamping plates to drive the chuck to clamp the material to be tested. The self-locking nature of the worm and worm wheel prevents the chuck from automatically loosening after clamping the material, preventing the material from moving when in contact with the measuring head, thereby improving the accuracy of the data obtained during testing;

[0019] 2. By arranging the screw, the clamping plate and the sliding top block at the top of the machine body, when the material is clamped and tested, the dust and impurities on the outer surface of the material will not fall into the inside of the screw, but will fall directly into the inside of the receiving tray. After use, the receiving tray can be taken out and cleaned with a brush, and then the receiving tray can be inserted into the inside of the machine body. When one end of the receiving tray is inserted into the machine body, the groove will push out the elastic pin. When the receiving tray is fully inserted into the inside of the machine body, the elastic pin will reset and engage with the receiving tray, making it easier to insert the receiving tray into the inside of the machine body and reducing dust and impurities from falling onto the outer surfaces of the lifting platform and the measuring head, thereby improving the accuracy of the measured data and allowing dust and impurities to be collected and conveniently cleaned.

[0020] 3. The L-shaped design of the chuck and the sliding block prevents the material from falling when placed between the chucks. When the first data measurement is completed, the clamping plate can be slightly loosened, and the sliding block can be moved by rotating the threaded rod with a handle. The distance between the sliding block can be accurately moved according to the scale line, allowing the sliding block to move the material at a fixed distance to obtain hardness data at different distances on the material.

[0021] 4. To replace the chuck according to the material to be measured, you need to twist the rotating pin to disengage the rotating pin from the elastic snap plate, then pull the rotating pin out of the chuck, and then pull the chuck out of the splint for replacement. Then you can insert the chuck that meets the requirements into the splint, and then insert the rotating pin into the chuck and rotate it to engage the rotating pin with the elastic snap plate, and then fix the splint and the chuck, which is convenient for replacing chucks of different sizes to clamp different materials, and there is no need to use screws for fixing.

[0031] The C-shaped design of the machine body 1 makes it convenient to observe and take materials when placing and measuring, and the inclined design of the machine body 1 allows the operator to better observe the display and control device. The plug-in and inverted design of the lifting platform 2 and the measuring head 3 can facilitate the replacement of worn measuring heads 3, and the brush 17 inserted on the side surface of the machine body 1 can be easily taken out to facilitate the cleaning of dust and impurities on the outer surface of the machine body 1.

[0032] The rotating and sliding mechanism includes: a worm 7, which is rotatably installed inside the machine body 1, and a screw 9 is rotatably installed inside the machine body 1, and the thread directions of the two ends of the screw 9 are opposite, a worm wheel 8 is fixedly installed on the outer surface of one end of the screw 9, and the worm wheel 8 is engaged with the worm 7, a splint 10 is slidably installed inside the machine body 1, and the outer surface of the splint 10 is penetrated by the screw 9, and the screw 9 and the splint 10 are threadedly connected, and a handle is fixedly installed on one end of the worm 7 located outside the machine body 1.

[0033] By rotating the worm 7, the worm wheel 8 is driven to rotate, and as the worm wheel 8 rotates, the screw 9 will rotate along with it. The rotation of the screw 9 will drive the clamps 10 on both sides to move closer to or away from the center at the same time, so that the block material can be approached and clamped by the clamp 11. The self-locking property of the worm 7 and the worm wheel 8 will automatically lock the position of the clamp 10 after the adjustment is completed and will not open automatically, so that the material will not be displaced due to contact with the measuring head 3 during measurement, thereby improving the accuracy of the measured data.

The moving distance can be accurately controlled by aligning the scale line 16 with the sliding top block 15 to obtain accurate hardness values ​​of different material spacings.

[0036] A receiving sliding mechanism is provided on the outer surface of one end of the machine body 1 close to the lifting platform 2, which can catch the dust and impurities dropped by the material during measurement, so that the dust and impurities will not fall into the interior of the screw 9 and the outer surface of the lifting platform 2.

[0040] The outer surface of the clamping plate 10 is provided with a snap-fitting and plug-in mechanism, through which parts can be removed for replacement and the object to be tested will not fall off.
