Description

Technical Field

[0001] This utility model relates to the technical field of workpiece testing devices, specifically a magnesium alloy product clamping and testing device. Background Technology

[0002] Magnesium alloys are lightweight metallic materials based on magnesium with added elements such as aluminum, zinc, and manganese. They are known for their low density, high specific strength, excellent shock absorption, and machinability. They are widely used in aerospace, automotive, and electronics industries to facilitate lightweight design, while also possessing good mechanical properties and corrosion resistance, making them an important material in modern industry.

[0003] However, in the current quality inspection of workpieces after processing, the commonly used method is for workers to check the flatness of the workpiece surface by visual observation or manual touch. This method relies on the operator's personal experience and subjective judgment, which can easily lead to incorrect inspection results. At the same time, it cannot accurately identify minute surface defects, which may affect the quality and performance of the final product. Utility Model Content

[0004] The purpose of this invention is to provide a clamping and testing device for magnesium alloy products to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

An air flow groove is provided on the upper surface of the positioning plate. Several air outlets communicating with the air storage chamber are provided in the air flow groove. The air outlets are connected through the air flow groove. The lower end face of the test workpiece blocks the air flow groove. A cover plate is placed on the test workpiece. A clamping assembly for clamping the cover plate is also symmetrically installed on the base plate.

[0007] Furthermore, the cover plate is provided with a handle, and the handle is symmetrically provided with countersunk holes communicating with the cover plate. Screws are threaded into the countersunk holes, and the cover plate and the handle are fixed together by the screws.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please refer to Figure 1-8 ;

[0027] A clamping and testing device for magnesium alloy products includes a base plate 1. Ribs 2 are symmetrically mounted on the upper surface of the base plate 1. Positioning plates 3 are fixedly mounted on the tops of the two ribs 2. A test workpiece 4 is placed on the positioning plates 3. A gas storage plate 5 is located at the bottom of the positioning plates 3. An air inlet 51 is located on one side of the gas storage plate 5. A gas storage chamber 52 communicating with the air inlet 51 is located inside the gas storage plate 5. The other end of the air inlet 51 is connected to an external gas supply device, through which gas is introduced into the gas storage chamber 52. Built-in pressure sensors and other detection elements are used to monitor and control gas pressure. The upper surface of the positioning plate 3 is provided with an airflow groove 31, and the airflow groove 31 has several air outlets 32 that communicate with the gas storage chamber 52. The air outlets 32 are connected through the airflow groove 31. When the test workpiece 4 is placed on the positioning plate 3, its lower end face will tightly fit and block the airflow groove 31. During the test, the external gas supply device supplies gas to the gas storage chamber 52 through the air inlet 51. The input gas flows out from the air outlets 32 and along the gas... The gas flows through the flow channel 31 until both the flow channel 31 and the gas storage chamber 52 are filled with gas. If the surface of the test workpiece 4 is uneven, the gas will escape from the tiny gap between the test workpiece 4 and the positioning plate 3. This will result in a small pressure change in the external gas supply device. Conversely, if the surface of the test workpiece 4 is flat, the gas will not easily overflow, thus maintaining a high pressure level in the external gas supply device. Therefore, by observing the change in the gas pressure reading on the external gas supply device, the flatness of the bottom surface of the test workpiece 4 can be determined. In order to avoid the test workpiece 4 from shifting or being blown up due to excessive gas pressure, which may affect the accuracy of the test, a cover plate 6 is placed on the test workpiece 4. A clamping assembly 7 for pressing the cover plate 6 is also symmetrically installed on the bottom plate 1. By applying appropriate pressure through the two clamping assemblies 7, the cover plate 6 is firmly pressed on the test workpiece 4, thereby ensuring the stability and sealing of the test workpiece 4 during the test, improving the reliability and accuracy of the flatness test, and ensuring the processing quality of the test workpiece 4.

[0028] In this embodiment, a handle 61 is provided on the cover plate 6. A countersunk hole 62 communicating with the cover plate 6 is symmetrically provided on the handle 61. A screw is threaded into the countersunk hole 62. The cover plate 6 and the handle 61 are fixedly installed together by the screw, so that the cover plate 6 is easy to pick up.

[0029] In this embodiment, the test workpiece 4 is symmetrically provided with several pressure heads 41, and the bottom of the cover plate 6 is provided with several positioning grooves 63 for the pressure heads 41 to be inserted. The cover plate 6 is symmetrically provided with limiting holes 64 on one side of the pressing assembly 7, and the top of the positioning plate 3 is symmetrically provided with limiting holes 33 corresponding to the limiting holes 64. Limiting pins 65 are inserted into the limiting holes 64, and the bottom of the limiting pins 65 is inserted into the limiting holes 33. Specifically, the positioning grooves 63 on the cover plate 6 are first aligned with the pressure heads 41 on the test workpiece 4, and then gently pressed down so that the pressure heads 41 are completely embedded in the positioning grooves 63, thereby realizing the connection between the cover plate 6 and the test workpiece 4. Then, the limiting pins 65 are sequentially inserted into the limiting holes 64 on the cover plate 6 and the limiting holes 33 on the positioning plate 3 to realize the installation and positioning of the cover plate 6 and the test workpiece 4 by the limiting pins 65.

[0030] In this embodiment, each pressing assembly 7 includes a cylinder 71. A pressing arm 72 is rotatably connected to the telescopic end of the cylinder 71. The other end of the pressing arm 72 is provided with a limiting pin 73. The cover plate 6 is provided with a positioning hole 66 corresponding to the limiting pin 73. The limiting pin 73 is used to insert into the positioning hole 66 to position the cover plate 6 and press it with the pressing arm 72. A support block 74 is also provided on one side of the telescopic end of the cylinder 71. The support block 74 is located between the telescopic end of the cylinder 71 and the positioning plate 3. Connecting plates 75 are rotatably connected to both sides of the support block 74. The other end of the connecting plate 75 is rotatably connected to the pressing arm 72. When the telescopic end of the cylinder extends or retracts, the pressing arm 72 will rotate around the connection between it and the connecting plate 75. Specifically, when the cylinder extends or retracts... When cylinder 71 is started, its telescopic end extends, driving the pressure arm 72 to rotate clockwise. As the pressure arm 72 gradually approaches the cover plate 6, its lower end face will make parallel contact with the upper end face of the cover plate 6, and apply uniform pressure to firmly press the cover plate 6. At the same time, the limiting pin 73 at the end of the pressure arm 72 will be inserted into the positioning hole 66 on the cover plate 6 to ensure that the cover plate 6 will not be displaced, thereby improving the stability of the cover plate 6 during operation and ensuring the pressing effect during the test. When the test is completed, the telescopic end of cylinder 71 descends, driving the pressure arm 72 to rotate counterclockwise, causing the limiting pin 73 to rise and disengage from the positioning hole 66, contacting the pressing and fixing of the test workpiece 4, so that the test workpiece 4 can be removed, and then the subsequent workpiece to be tested can be placed.
