[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Refer to Figure 1- Figure 4 As shown, this utility model provides a technical solution: a machine tool fault diagnosis and detection device, including a detection device body 1, a plurality of operation buttons 2 installed on the surface of the detection device body 1, an information screen 3 installed on the surface of the detection device body 1, a wiring port 4 provided on the surface of the detection device body 1, a connector 5 electrically connected inside the wiring port 4, a connecting wire 6 fixedly connected to the surface of the connector 5, a first slide 7 fixedly connected to the surface of the detection device body 1, a threaded rod 8 threadedly connected to the inner wall of the first slide 7, an arc-shaped clamp 10 rotatably connected to one end of the threaded rod 8, the inner wall of the arc-shaped clamp 10 abutting against the connector 5, and a rotating shaft 9 fixedly connected to the other end of the threaded rod 8. By setting the first slide 7,

[0023] The structure includes a threaded rod 8 and an arc-shaped clamping plate 10. Rotating the shaft 9 moves the threaded rod 8 within the first slide 7, causing the arc-shaped clamping plate 10 to clamp the connector 5. This provides a stable and limited position for the connector 5, preventing loosening or poor contact due to machine tool vibration, ensuring wiring stability and the reliability of the testing device. It also improves the continuity and accuracy of the fault diagnosis and testing process, reducing the risk of misjudgment or testing interruption caused by connection problems. Several circular blocks 11 are fixedly connected to the inner wall of the arc-shaped clamping plate 10. These circular blocks 11 are evenly distributed on the inner wall of the arc-shaped clamping plate 10 and are elastic bodies. When clamping the connector 5, the elastic circular block 11 can utilize its elasticity to buffer the clamping force, preventing damage to the connector 5. It also increases the friction between the block and the connector 5, further improving the stability of the connector 5. Two second slides 12 are fixedly connected to the surface of the detection device body 1, and two slide rods 13 are fixedly connected to the arc surface of the arc-shaped clamping plate 10. The slide rods 13 are slidably connected to the inner wall of the second slides 12. The sliding engagement of the slide rods 13 and the second slides 12 provides guidance for the arc-shaped clamping plate 10, ensuring that the arc-shaped clamping plate 10 moves in a straight line when clamping or releasing the connector 5, avoiding deviation or skew, and improving the accuracy and stability of clamping the connector 5. Several anti-slip grooves 14 are formed on the arc surface of the rotating shaft 9, and these grooves are evenly distributed in a circumferential array on the arc surface of the rotating shaft 9. The anti-slip grooves on the surface of the rotating shaft prevent the operator from slipping during rotation. The surface of the detection device body 1 has four circular grooves 15. A spring 16 is fixedly connected to the inner wall of each groove 15. A circular rod 17 is fixedly connected to one end of each spring 16. The circular rod 17 is slidably connected to the inner wall of the groove 15. A buffer block 18 is fixedly connected to the end of the circular rod 17 away from the spring 16. When the detection device body 1 is subjected to collision or vibration, the cooperation of the spring 16, the circular rod 17, and the buffer block 18 can absorb and buffer external forces through the deformation of the spring 16, reducing the impact on the internal components of the device, protecting the stability of the device structure and electronic components, and reducing the risk of damage caused by vibration or impact. A buffer pad 19 is fixedly connected to the arc surface of the buffer block 18. The buffer pad 19 is made of silicone rubber. The arc surface of the operation button 2 is coated with a waterproof coating 20, which is an organosilicon resin-based waterproof coating 20.

[0024] Working principle: The detection device body 1 serves as the core carrier, with operation buttons on its surface.

[0025] 2. Used to receive user function commands (such as parameter settings, detection and startup, etc.), information screen 3.

[0026] It displays real-time detection data, fault analysis results, and other information. The connection port 4, together with the connector 5 and the connecting wire 6, forms a signal transmission channel between the device and the machine tool, used to collect vibration signals from machine tool bearings, spindles, and other components.

[0027] In terms of the connection and fixing mechanism, rotating the shaft 9 drives the threaded rod 8 to move along the threaded trajectory within the first slide 7, thereby pushing the arc-shaped clamping plate 10 closer to the connector 5. At this time, the sliding rods 13 on both sides of the arc-shaped clamping plate 10 slide synchronously along the inner wall of the second mounting bracket, providing precise guidance for the arc-shaped clamping plate 10 and ensuring that it always moves in a straight line, avoiding misalignment due to deviation. When the arc-shaped clamping plate 10 contacts the connector 5, the elastic circular block 11 on the inner wall deforms under pressure. On the one hand, it prevents excessive clamping force from damaging the connector 5 through elastic buffering; on the other hand, it increases friction by utilizing the tight fit after deformation, while adapting to the shape of connectors 5 of different sizes, achieving a stable clamping of the connector 5, effectively resisting the risk of loosening caused by machine tool vibration, and ensuring the continuity and stability of vibration signal transmission.

[0028] In terms of the protection mechanism, when the device is subjected to external collision or vibration transmitted from the machine tool, the buffer block 18 first contacts the external force, which drives the round rod 17 to slide along the inner wall of the round groove 15 and compress the spring 16. The spring 16 absorbs the impact energy through elastic deformation, converting the external force into elastic potential energy, which greatly reduces the impact force transmitted to the inside of the device, thereby protecting the internal circuits and other components from damage.

[0029] In addition, the silicone resin-based waterproof coating 20 on the surface of the operation button 2 forms a dense film, which uses low surface tension to prevent coolant and oil from penetrating. At the same time, it has good adhesion and flexibility, so it can withstand the deformation of the button without falling off. The wear-resistant additive enhances the scratch resistance and effectively protects the internal circuit of the button, making it suitable for machine tool environments with many liquids and high oil content.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
