Description

Technical Field

[0001] This utility model relates to the field of material testing equipment technology, and in particular to a high-efficiency fixture device for testing the friction and wear of nickel-based high-temperature alloy cutting tools. Background Technology

[0002] Nickel-based superalloys are widely used in the manufacture of cutting tools in aerospace, energy and other fields due to their excellent high-temperature strength, oxidation resistance and corrosion resistance.

[0003] However, during use, the friction and wear performance of cutting tools directly affects their service life and machining quality. Currently, existing fixture devices for friction and wear testing of nickel-based superalloy cutting tools have many problems. For example, it is difficult to control the clamping pressure to maintain stability during friction testing. In addition, existing equipment requires friction testing first, and then the friction-tested tool needs to be transferred to a professional high-precision testing instrument for further testing. The testing and grinding processes are independent, resulting in low testing efficiency.

[0004] To address the shortcomings of the aforementioned technologies, we propose a high-efficiency fixture device for testing the friction and wear of nickel-based superalloy cutting tools. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency fixture device for testing the friction and wear of nickel-based high-temperature alloy cutting tools.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency clamping device for testing the friction and wear of nickel-based high-temperature alloy cutting tools includes a structural support. A clamping assembly and a wear resistance testing assembly are disposed on the inner side of the structural support. The clamping assembly includes a structural base, which is fixedly mounted on the inner side of the structural support. A hydraulic rod is fixedly mounted on the upper side of the structural base. The output end of the hydraulic rod passes through the inner side of the structural base, and a pressure sensor is fixedly mounted on the output end of the hydraulic rod. An upper clamping plate is fixedly mounted below the pressure sensor. A lower clamping plate is fixedly mounted at the bottom inner side of the structural base. Clamping pads are fixedly mounted on the inner sides of both the upper and lower clamping plates. A lampshade is disposed on the side of the structural base, and a supplementary light tube is fixedly mounted inside the lampshade.

[0008] Furthermore, the clamping pad is evenly provided with transverse raised textures.

[0009] Furthermore, a connecting rod is fixedly installed on the side of the structural base, and the lower end of the connecting rod is fixedly connected to the lampshade.

[0010] Furthermore, the inner side of the lampshade is provided with a reflective mirror surface, and the inner side of the clamping pad is provided with a nickel-based high-temperature alloy cutting tool.

[0011] Furthermore, the wear resistance testing component includes an electric push rod, a mounting block is fixedly installed on the output end of the electric push rod, a servo motor is fixedly installed on the mounting block, a rotating shaft is fixedly installed on the output end of the servo motor, and a friction disc is screwed onto the lower end of the rotating shaft.

[0012] Furthermore, a number of lateral connecting plates are fixedly connected between the output end sidewall of the electric push rod and the mounting block.

[0013] Furthermore, a 3D optical profilometer is fixedly installed on the upper side of the structural support, and a folding plate is fixedly installed on the side of the structural support, with the folding plate being fixedly connected to the bottom of the electric push rod.

[0016] Compared with related technologies, the efficient fixture device for testing the friction and wear of nickel-based high-temperature alloy cutting tools proposed in this utility model has the following advantages:

[0017] This invention discloses a high-efficiency clamping device for testing the friction and wear of nickel-based superalloy cutting tools. Through a clamping assembly, activating a hydraulic rod drives an upper clamping plate to move an upper clamping pad closer to a lower clamping pad, thus clamping the cutting tool between the two clamping pads. The extension freedom of the hydraulic rod allows the device to clamp cutting tools of different sizes. Furthermore, a pressure sensor at the end of the hydraulic rod accurately reflects the clamping force provided by the hydraulic rod. A controller precisely controls the clamping force provided by the hydraulic rod, ensuring a stable clamping effect for the cutting tool, improving stability during the testing process, and ensuring smooth operation. Additionally, a supplementary light tube is provided on the side, aligned with the friction test surface. A high-precision 3D optical profilometer on the upper side accurately monitors the friction condition of the polished surface. In testing nickel-based superalloy cutting tools, the device can obtain quantitative data such as wear volume and depth by accurately measuring the surface profile changes after tool wear, allowing friction testing and wear detection to be performed simultaneously, improving the efficiency of the testing process and enhancing its practicality.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1-6 A high-efficiency clamping device for testing the friction and wear of nickel-based high-temperature alloy cutting tools includes a structural support 1, a clamping assembly 6 and a wear resistance testing assembly 7 disposed on the inner side of the structural support 1; the clamping assembly 6 includes a structural seat 61, which is fixedly installed on the inner side of the structural support 1, a hydraulic rod 62 is fixedly installed on the upper side of the structural seat 61, the output end of the hydraulic rod 62 passes through to the inner side of the structural seat 61 and a pressure sensor 63 is fixedly installed on the output end of the hydraulic rod 62, an upper clamping plate 64 is fixedly installed on the lower side of the pressure sensor 63, a lower clamping plate 65 is fixedly installed on the bottom inner side of the structural seat 61, clamping pads 66 are fixedly installed on the inner sides of both the upper clamping plate 64 and the lower clamping plate 65, and a lamp cover 68 is disposed on the side of the structural seat 61, with a supplementary light tube 69 fixedly installed inside the lamp cover 68.

[0027] In this method, the wear resistance test assembly 7 includes an electric push rod 71, an installation block 72 is fixedly installed on the output end of the electric push rod 71, a servo motor 74 is fixedly installed on the installation block 72, a rotating shaft 75 is fixedly installed on the output end of the servo motor 74, a friction disc 76 is screwed to the lower end of the rotating shaft 75, and several lateral connecting plates 73 are fixedly connected between the side wall of the output end of the electric push rod 71 and the installation block 72.

[0028] With the above setup, when the servo motor 74 starts, it drives the friction disk 76 to rotate. Subsequently, the electric push rod 71 is activated to drive the friction disk 76 closer to the clamped tool, so that friction testing can be performed. In this device, the friction disk 76 is fixed to the lower end of the rotating shaft 75 by screw connection, which makes it easy to replace the friction disk 76 with different roughness for testing, thus improving applicability.

[0029] In this method, a 3D optical profilometer 3 is fixedly installed on the upper side of the structural support 1, a folding plate 2 is fixedly installed on the side of the structural support 1, the folding plate 2 is fixedly connected to the bottom of the electric push rod 71, and a high-definition display screen 4 and a controller 5 are fixedly installed on the outer side of the structural support 1.

[0030] Through the above-described setup, the 3D optical profilometer 3 can accurately measure the surface profile changes after wear in the testing of nickel-based superalloy cutting tools, obtaining quantitative data such as wear volume and depth. For example, under different working conditions, after a certain period of friction and wear, this instrument can clearly present the microscopic morphology of pits, scratches, etc., caused by wear on the tool surface, thereby analyzing the degree of wear. Under test conditions of high load and high sliding speed, deep scratches will appear on the surface of nickel-based superalloy cutting tools. After the 3D optical profilometer is equipped with a suitable objective lens, it can effectively measure and clearly image these scratches, providing intuitive and accurate data support for in-depth research on the tool wear mechanism. The above are all existing technical means and will not be elaborated here. The high-definition display screen 4 is used to display the microscopic morphology of pits, scratches, etc. on the tool surface detected by the 3D optical profilometer 3.

[0031] In this method, the clamping pad 66 is provided with transverse raised textures evenly distributed.

[0032] By setting it in the above manner, the horizontal raised texture improves the clamping stability of the clamping pad 66.

[0033] In this configuration, a connecting rod 67 is fixedly installed on the side of the structural base 61, and the lower end of the connecting rod 67 is fixedly connected to the lampshade 68.

[0034] In this method, the inner side of the lampshade 68 is provided with a reflective mirror, and the inner side of the clamping pad 66 is provided with a nickel-based high-temperature alloy cutting tool 8.

[0035] The above-mentioned setup creates a light-focusing and reflective effect inside the lampshade 68, making the light tube 69 illuminate the tool friction test surface more clearly, which is convenient for observation by the 3D optical profilometer.

[0036] In this method, an installation groove 610 is provided on the inner side of the structural base 61, a cleaning groove 611 is fixedly installed inside the installation groove 610, a dustproof net 612 is fixedly installed at the port of the cleaning groove 611, several fans 614 are fixedly installed inside the cleaning groove 611, an air inlet pipe 613 is fixedly installed at the air inlet of the fan 614, and the air inlet pipe 613 passes through to the outside of the cleaning groove 611.

[0037] With the above setup, after the friction test, the fan inside the cleaning groove 611 is activated, which generates a blowing effect at the port of the cleaning groove 611. This blows away the dust and debris generated during the grinding process from the clamping pad 66, preventing it from remaining on the clamping pad 66 and causing scratches to the tool when it is clamped again.

[0038] The working principle of the high-efficiency fixture device for testing the friction and wear of nickel-based high-temperature alloy cutting tools provided by this utility model is as follows:

[0039] In use, the hydraulic rod 62 in the clamping assembly 6 serves as the power source, clamping and releasing the tool through its telescopic movement. A pressure sensor 63 is installed between the output end of the hydraulic rod 62 and the upper clamping plate 64, enabling real-time monitoring of the clamping force applied to the tool by the hydraulic rod 62. This sensor converts the force signal into an electrical signal and transmits it to the controller 5. The controller 5 precisely controls the working state of the hydraulic rod 62 according to preset clamping force parameters, ensuring the tool receives a stable and appropriate clamping force during testing. This prevents tool deformation and damage due to excessive clamping force, or test stability issues due to insufficient clamping force. The evenly distributed transverse raised textures on the clamping pad 66 increase friction with the tool surface, further improving clamping stability. The servo motor 74 is then activated. The moving friction disk 76 rotates, and the subsequent start-up electric push rod 71 drives the friction disk 76 to move closer to the clamped tool for friction testing. The 3D optical profilometer 3 performs non-contact measurement on the tool surface based on principles such as optical interference or laser scanning. When light shines on the tool surface, the optical path of the reflected light changes due to differences in surface morphology. The 3D optical profilometer 3 reconstructs the three-dimensional morphology of the tool surface by analyzing these changes in optical path. The lighting system composed of the supplementary light tube 69 and the lamp cover 68 provides sufficient and uniform light for the 3D optical profilometer 3, ensuring the accuracy and reliability of the measurement. The high-definition display screen 4 is connected to the controller 5, which presents the processed tool surface micromorphology data in visual form, facilitating real-time observation and analysis by the testers.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
