It adopts advanced ultra-fine particle carbide substrate and combines chemical vapor deposition technology to coat high-hardness diamond. It has extremely high wear resistance, thermal stability and anti-adhesion properties. Its unique cutting edge design can significantly improve cutting accuracy and surface quality, effectively extend service life and reduce tool change frequency. It is particularly suitable for aerospace, mold manufacturing, new energy and other processing scenarios with extremely high requirements for high precision and high efficiency. It is an ideal choice for improving processing performance and reducing overall costs.

[0003] But at the same time, in the actual testing process, in order to ensure the representativeness and accuracy of the hardness data, multi-point tests are usually required at multiple different locations to evaluate the uniformity of the coating distribution and the overall performance, which puts higher demands on the testing efficiency; however, the traditional multi-point hardness testing method usually adopts a single-point sequential drive test mode, and each test requires repositioning, loading, and recording of data. The process is cumbersome and the cycle is long, which not only seriously limits the test efficiency, but is also prone to errors due to human intervention or environmental changes, making it difficult to meet the needs of efficient batch testing.

Detailed implementation manners

[0030] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0031] Embodiment: As Figures 1-9As shown in the figure, a hardness testing device for a new material diamond graphite milling cutter according to the present invention includes a lifting plate 1 on a lift that is vertically slidably mounted on a testing machine body, and further includes: a transverse movement assembly 2 that is transversely slidably mounted on the upper part of the lifting plate 1; a flipping assembly 3 fixed on the transverse movement assembly 2; a linkage assembly 6 for linking the transverse movement assembly 2 and the flipping assembly 3; a clamping assembly 4 provided at the flipping part of the flipping assembly 3, and the clamping assembly 4 is used for clamping and mounting the new material diamond graphite milling cutter. When the lifting plate 1 makes a lifting movement, the transverse movement assembly 2 is synchronously driven to move, and the transverse movement assembly 2 drives the flipping assembly 3 to drive the milling cutter clamped by the clamping assembly 4 to make a flipping action, so as to realize a multi-axis movement detection action.

[0032] For the above-mentioned hardness testing device for a new material diamond graphite milling cutter, by using the lift on the testing machine body as the main power source, the automation, integration and high efficiency of the multi-point hardness testing process of the milling cutter are realized.

[0033] Specifically, a lifting plate 1 that can be vertically slidably mounted on the testing machine body is provided, and the lifting plate 1 moves up and down under the drive of the lift; a transversely sliding transverse movement assembly 2 is installed above the lifting plate 1. When the lifting plate 1 rises and falls with the lift, the transverse movement assembly 2 will synchronously move horizontally under the guiding action of the track structure of the lifting plate 1, so that the milling cutter clamped at the front end of the device realizes a preset displacement in the horizontal direction.

[0034] A flipping assembly 3 is also installed on the transverse movement assembly 2. The flipping assembly 3 is connected to the transverse movement assembly 2 through a linkage assembly 6. As the transverse movement assembly 2 moves, the linkage assembly 6 drives the flipping assembly 3 to rotate, so that the clamping assembly 4 on the flipping assembly 3 changes its angle, realizing the attitude adjustment of the milling cutter.

[0035] During the whole process, the clamping assembly 4 clamps the diamond graphite milling cutter to be tested. As the lifting plate 1 rises and falls, the longitudinal positioning of each measuring point is completed. At the same time, with the cooperation of synchronous horizontal movement and flipping actions, accurate tests at multiple positions and angles are automatically realized.

[0036] The advantage is that all actions are triggered by the single lifting control of the lift, and the linkage structure can automatically complete the horizontal movement and flipping actions, avoiding the problem of separately and independently controlling multi-axis drive modules in the traditional testing process, greatly reducing the complexity of the control system, improving the testing efficiency and stability, and providing an efficient and intelligent solution for the large-scale and high-precision detection of new material milling cutter products.

[0037] Among them, the transverse movement component 2 includes a small transverse movement gear 202 engaged with a vertical rack fixed on the test body. When the lifting plate 1 is lifted or lowered, the small transverse movement gear 202 is synchronously driven to rotate, and a slide plate 204 is slidingly installed on the upper part of the lifting plate 1. The small transverse movement gear 202 rotatably installed on one side of the lifting plate 1 is also meshed and connected with the large transverse movement gear 201 rotatably installed on one side of the lifting plate 1. One end of the screw rod 203 rotatably installed inside the lifting plate 1 passes through the lifting plate 1 and is fixedly connected to the large transverse movement gear 201, and the outside of the screw rod 203 is screwed to the slide plate 204. When the screw rod 203 rotates, the slide plate 204 is synchronously controlled to perform a transverse movement on the upper part of the lifting plate 1.

[0038] The linkage structure of the lateral movement component 2 based on the combination of gear meshing and the transmission of the screw rod 203 realizes the lateral movement function driven by the lifting action.

[0039] Specifically, the transverse movement assembly 2 is provided with a small transverse movement gear 202 that meshes with the vertical rack fixed on the test body. When the lifting plate 1 moves vertically under the drive of the elevator, the small transverse movement gear 202 always maintains a meshing relationship with the fixed rack, and the gear rotates passively during the lifting process.

[0040] The small transverse gear 202 is meshed and linked with the large transverse gear 201 installed on one side of the lifting plate 1, thereby driving the large transverse gear 201 to rotate synchronously. One end of the screw rod 203 is fixedly installed at the center position of the large transverse gear 201. As the large transverse gear 201 rotates, the screw rod 203 is driven to rotate. The outside of the screw rod 203 is screwed with a nut structure for supporting the slide plate 204. When the screw rod 203 rotates, due to the principle of thread transmission, the slide plate 204 will move linearly laterally along the guide rail on the upper part of the lifting plate 1, thereby realizing the lateral adjustment of the milling cutter clamping position.

[0041] Then, the power generated by the lifting action is used to indirectly drive the small gear, large gear and screw 203 to work together as a whole, cleverly realizing the passive drive of the lateral movement without the need for an additional lateral drive motor or control module, significantly simplifying the system structure, reducing energy consumption and costs, while ensuring the synchronization and stability of the lateral movement process, which is conducive to high-precision position adjustment during multi-point hardness testing.

[0042] Among them, the linkage assembly 6 includes a linkage gear plate 601 fixed to the inside of the lifting plate 1, and a linkage gear 602 rotatably mounted on the lower part of the slide 204 is meshed with the rack. When the slide 204 moves, the linkage gear 602 is synchronously driven to rotate. The second rotating rod 603 fixed on one side of the linkage gear 602 passes through the slide 204 and is connected to the linkage rod 605 through the universal joint 604. The linkage gear 602 rotates and the linkage rod 605 is synchronously driven to rotate. The flip assembly 3 includes a support plate 301 fixed on the upper part of the slide 204. One side of the support plate 301 is fixed It is fixedly connected with an arc-shaped rack rail 302, and the clamping assembly 4 includes a rotating tube 401. One end of the rotating tube 401 is fixedly connected with a flip gear 304 that is meshed with the arc-shaped tooth plate. When the linkage rod 605 rotates, the angle of the rotating tube 401 is changed by the flip gear 304 and the rotating tube 401 is driven to rotate. One side of the support plate 301 is also fixedly connected with an arc-shaped guide plate 303. The support plate 301 is slidably installed with a mounting seat 402 through the arc-shaped guide plate 303. The mounting seat 402 is provided with a slide groove 403 that matches the shape of the arc-shaped guide plate 303 on the side close to the support plate 301.

[0043] The linkage assembly 6 converts the linear lateral movement of the slide plate 204 into an angular change movement of the flip assembly 3, realizing mechanical automatic linkage. The linkage assembly 6 includes a linkage tooth plate 601 installed inside the lifting plate 1, and a linkage gear 602 arranged below the slide plate 204 and meshing with the linkage tooth plate 601. When the slide plate 204 slides laterally above the lifting plate 1 under the drive of the screw rod 203, since the linkage tooth plate 601 is a fixed component, the linkage gear 602 rotates during the relative motion. A second rotating rod 603 is connected to one side of the linkage gear 602. The rotating rod passes through the slide plate 204 and is connected to the linkage rod 605 through a universal joint 604. As the linkage gear 602 rotates, the rotating rod is driven to rotate. At the same time, the universal joint 604 ensures the adjustability of the rotation direction and the stability of the transmission, so that the linkage rod 605 rotates synchronously. This structure realizes the natural transition from sliding motion to angular motion by generating rotation through lateral movement without adding an additional drive motor, providing a power basis for the subsequent flip assembly 3, while improving the system's integration and stability.

[0044] The linkage component 6 converts the linear lateral movement of the sliding plate 204 into an angular change movement of the flipping component 3, achieving mechanical automatic linkage. The linkage component 6 includes a linkage toothed plate 601 installed inside the lifting plate 1, and a linkage gear 602 arranged below the sliding plate 204 and meshing with the linkage toothed plate 601. When the sliding plate 204 makes a lateral slide along the upper part of the lifting plate 1 driven by the lead screw 203, since the linkage toothed plate 601 is a fixed component, the linkage gear 602 rotates during the relative movement. One side of the linkage gear 602 is connected to a second rotating rod 603, and this rotating rod passes through the sliding plate 204 and is connected to the linkage rod 605 through a universal joint 604. As the linkage gear 602 rotates, the rotating rod is driven to rotate. At the same time, the universal joint 604 ensures the adjustability of the rotation direction and the stability of the transmission, causing the linkage rod 605 to rotate synchronously. This structure realizes generating rotation through lateral movement without adding an additional drive motor, completing a natural transition from sliding motion to angular motion, providing a power basis for the subsequent flipping component 3, and improving the integration and stability of the system.

[0045] The core function of the flipping component 3 is to cooperate with the linkage component 6 to complete the flipping action of the clamping milling cutter, achieving hardness tests in multiple directions and at multiple angles.

[0046] The main structure is composed of a support plate 301 fixed to the upper part of the sliding plate 204. An arc-shaped toothed rail 302 is arranged on one side of the support plate 301, providing an arc-shaped path for the flipping movement of the rotating tube 401. The rotating tube 401 in the clamping component 4 is installed on the support plate 301, and one end of it is fixedly connected to a flipping gear 304 arranged on the arc-shaped toothed rail 302, forming a rotating transmission system.

[0047] When the linkage rod 605 rotates driven by the linkage component 6, the rotation action is transmitted to the flipping gear 304, and the flipping gear 304 drives the rotating tube 401 to rotate around the axis, realizing the flipping and angle adjustment of the clamping part. To ensure the smoothness and path accuracy of the flipping process, the support plate 301 is also fixedly connected with an arc-shaped guide plate 303 corresponding to the shape of the arc-shaped toothed rail 302. The mounting seat 402 forms a limiting sliding connection with the guide plate through the opened sliding groove 403, ensuring that the rotating tube 401 moves along the preset trajectory during the flipping process, avoiding deviation or jamming. The overall structure does not require an independent flipping drive device and can achieve precise flipping only through the linkage structure, ensuring the rapidity, stability, and repeatability of the test point switching, and providing technical support for batch and multi-direction hardness detection.

[0048] Among them, the rotating pipe 401 is rotatably installed inside the mounting seat 402, and a self-adjusting component 5 for the milling cutter to contact is also installed on one side of the rotating pipe 401. The self-adjusting component 5 includes a support frame 501 fixed to the outside of the rotating pipe 401. Two rotating wheels 502 are rotatably installed inside the support frame 501. The two rotating wheels 502 are drivingly connected by a transmission belt 503. A fitting groove 504 conforming to the shape of the rod part of the milling cutter is formed on the outside of the transmission belt 503. During use, the rotating pipe 401 rotates, and one of the rotating wheels 502 is driven to rotate through a transmission member 404, so as to realize the support test of different positions of the rod part of the milling cutter. The transmission member 404 includes a support seat 4044 fixed to the outside of the rotating pipe 401. One end of a first rotating rod 4041 rotatably installed on the upper part of the support seat 4044 is fixedly connected with a transmission gear 4045. The transmission gear 4045 is meshed with an annular tooth groove formed inside the mounting seat 402. When the rotating pipe 401 rotates, the first rotating rod 4041 is synchronously driven to rotate. The other end of the first rotating rod 4041 is fixedly connected with a first bevel gear 4042. The first bevel gear 4042 is meshed with a second bevel gear 4043 fixed to the outside of one of the rotating wheels 502. When the first rotating rod 4041 rotates, the rotating wheel 502 is driven to drive the transmission belt 503 to rotate. There are three self-adjusting components 5, and the three self-adjusting components 5 cooperate with the clamping component 4 to contact the milling cutter to perform a self-adjusting clamping action.

[0049] In view of the need for the diamond graphite milling cutter to detect the support of different positions during the multi-point and multi-angle hardness tests, a clamping component 4 structure that can realize self-adjusting clamping and can flexibly change the position of the support point is proposed. The core lies in the self-adjusting component 5 installed outside the rotating pipe 401 and its cooperating transmission system.

[0050] Specifically, the self-adjusting component 5 includes a support frame 501 fixed to the outside of the rotating pipe 401. Two rotatably installed rotating wheels 502 are arranged inside the support frame 501. Synchronous movement is realized between the rotating wheels 502 through a transmission belt 503. A fitting groove 504 matching the shape of the rod part of the milling cutter is formed on the outside of the transmission belt 503. After the milling cutter is installed in the clamping component 4, the fitting groove 504 can flexibly fit it, so that the support of the milling cutter during the test is both stable and has a certain flexibility, thereby effectively avoiding measurement errors or slipping phenomena caused by uneven stress.

[0051] To further improve the flexibility and adaptability during the test, the present invention is provided with a complete mechanical transmission structure to realize the synchronous drive of the transmission belt 503.

[0052] The rotating tube 401 serves as the main rotating mechanism, and its rotation process can drive a whole set of transmission systems to complete coordinated actions. A support base 4044 is fixed to the outside of the rotating tube 401, and a first rotating rod 4041 is rotatably installed on the upper part of the support base 4044. One end of the rotating rod is meshed and connected with the annular tooth groove inside the mounting base 402 through a transmission gear 4045. When the rotating tube 401 rotates, the transmission gear 4045 rotates accordingly, thereby driving the first rotating rod 4041 to rotate. A first bevel gear 4042 is installed at the other end of the first rotating rod 4041, which is meshed and connected with a second bevel gear 4043 arranged on the outside of one of the rotating wheels 502, completing the secondary transmission of power.

[0053] Finally, the second bevel gear 4043 drives the wheel 502 to rotate, thereby driving the entire transmission belt 503 to run synchronously on its guide path. This series of actions enables the matching groove 504 outside the transmission belt 503 to contact the milling cutter rod at different positions, thereby realizing the switching of the detection point.

[0054] The transmission member 404 is an optional structure, that is, the user can choose to install or remove the transmission member 404 during use, and decide whether to enable the synchronous movement function of the transmission belt 503 according to actual test requirements.

[0055] Under normal testing conditions, the equipment can complete routine testing tasks using only three basic movements: lifting, lateral movement, and flipping. When it is necessary to test the support strength of different positions of the milling cutter or implement a multi-point support strategy, the transmission part 404 can be installed to activate the transmission system, so that the transmission belt 503 can automatically move with the rotating wheel 502 to perform support testing on the milling cutter rod point by point.

[0056] This structural design not only enhances the device's versatility and applicability, but also significantly improves the flexibility of the testing process and the integrity of the data. The three self-adjusting components 5 form a stable, multi-point support network when clamping the milling cutter. Regardless of whether the linkage mechanism is engaged or not, this ensures that the cutter remains securely clamped throughout the entire turning and positioning process, further enhancing the accuracy and repeatability of test results.

[0057] During operation, the hardness testing device for diamond graphite milling cutters uses the elevator as the main power source and realizes multi-point and multi-angle hardness testing of the milling cutter through the cooperation of the lifting plate 1, the transverse movement assembly 2, the flipping assembly 3, and the linkage assembly 6. The lifting plate 1 moves up and down driven by the elevator and drives the transverse movement assembly 2 to move horizontally. The transverse movement assembly 2 converts the vertical movement of the lifting plate 1 into a lateral movement through the gear and lead screw 203 structure, ensuring that the milling cutter moves along a preset trajectory during the testing process. The transverse movement assembly 2 also drives the flipping assembly 3 to rotate through a linkage structure, thereby adjusting the angle of the clamping assembly 4, changing the position and angle of the milling cutter, and ensuring the accurate positioning of the testing points. Specifically, the lifting and lowering drive of the lifting plate 1 causes the transverse movement assembly 2 to move synchronously, and the transverse movement assembly 2 drives the flipping assembly 3 to change the posture of the milling cutter through a linkage mechanism. Without additional motors or control modules, the transverse movement and flipping actions are driven by the lifting and lowering of the lifting plate 1, greatly simplifying the system structure. The clamping assembly 4 firmly clamps the diamond graphite milling cutter throughout the process, and through the cooperation of the self-adjusting assembly 5 and the transmission belt 503, the position of the support point is flexibly changed to ensure the stable clamping and multi-point support of the milling cutter. This design not only improves the degree of automation but also ensures the accuracy and high precision of the testing.

[0058] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
