Description
Technical Field
[0001] This utility model relates to the field of monitoring technology, and in particular to a detector for overhauling CNC machine tools. Background Technology
[0002] In modern manufacturing, the emergence of CNC machine tools has completely revolutionized machining methods, empowering countless industries. Their superior precision, efficiency, and intelligence have reshaped the landscape of machining and become a key force driving the vigorous development of society. However, even precision CNC machine tools can develop minor faults under long-term, high-intensity operation. In order to identify these faults in a timely and accurate manner and ensure smooth production, spotlights were created.
[0003] The spotlight used for inspecting CNC machine tools is a crucial precision inspection tool. The main body is equipped with a high-brightness light source that can generate strong light and penetrate into every corner of the CNC machine tool. The spotlight also has detection sensors that can detect a variety of key parameters and even tiny defects on the surface of parts, providing strong technical support for the efficient maintenance and precise upkeep of CNC machine tools.
[0004] However, the illumination angle of the spotlights used for CNC machine tool maintenance is fixed and difficult to adjust flexibly to meet the maintenance needs of different positions and angles. In some dimly lit CNC machine tool maintenance environments, the light intensity of the spotlight is insufficient to provide a clear field of vision. The light emitted by the spotlight is unevenly distributed in the illuminated area, resulting in bright and dark spots or unnatural transitions between light and dark areas. The existing solution is to design adjustable-angle lamps and brackets and use intelligent control to automatically adjust the light intensity according to the ambient light and actual needs. However, in some complex internal structures of machine tools, even if the angle is adjustable, there are still some blind spots that are difficult to illuminate, making it difficult to achieve completely uniform illumination. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a spotlight for inspecting CNC machine tools, aiming to improve the problem of uneven illumination of the machine tool interior in the prior art.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a detector for inspecting CNC machine tools, comprising a housing, a connecting frame, and a base. A servo motor is fixedly connected to the front side of the inner wall of the housing, and a gear turntable is fixedly connected to the output end of the servo motor.

A microprocessor is fixedly connected to the top right end. Electric telescopic rods are fixedly connected to the front and rear sides of the left end of the connecting frame. Lamp holders are rotatably connected to the left ends of both electric telescopic rods. A distance sensor is fixedly connected to the front left side of the lamp holder, and an angle sensor is fixedly connected to the rear left side of the lamp holder. A lampshade is fixedly connected to the left end of the lamp holder. An electric telescopic rod is fixedly connected to the middle top of the base. An inspection cover is threaded onto the bottom end of the outer casing. A locking mechanism is provided at the bottom end of the base to fix the detector.
[0007] As a further description of the above technical solution:
[0008] The locking mechanism includes a threaded hole located at the center of the bottom end of the base. A washer is fixedly connected to the inner wall of the threaded hole, and a bolt is threadedly connected to the inner wall of the washer.

Multiple sliding grooves are provided inside the base, and the multiple sliding rods are slidably connected to the multiple sliding grooves respectively. Multiple strong magnets are fixedly connected to the bottom end of the base.
[0009] As a further description of the above technical solution:
[0010] The lamp holder has multiple heat-conducting pipes fixedly connected inside, and a heat dissipation pipe fixedly connected to the outside of the lamp holder.
[0011] As a further description of the above technical solution:

[0013] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the distance sensor and angle sensor are activated to detect the parts that need to be inspected and the results are fed into the microprocessor. At the same time, the servo motor is activated to make the gear turntable rotate. Because the ball screw engages with the slot, the gear turntable drives the rack to rotate around the top of the outer shell and adjusts its position according to the detection results. The electric telescopic rod 2 adjusts the detector back and forth so that the inside of the machine tool can be fully illuminated by the detector, avoiding the situation of blind spots and dim visibility.

First, the bolts are removed from the fixing plate, the fixing plate is pulled out from the base, and then the detector is attracted to the machine tool using a strong magnet. After that, from the other side of the machine tool where it was attracted, the fixing plate and the sliding rod are reinserted into the slide groove. Finally, the bolts are screwed back into the threaded hole, and the bolts are fixed by the washers, thus avoiding the situation where the detector is not securely fixed by magnetic attraction alone.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a detector for inspecting CNC machine tools, comprising a housing 1, a connecting frame 8, and a base 2. A servo motor 4 is fixedly connected to the front inner wall of the housing 1, providing power for the left and right rotation of a rack 6. A gear turntable 5 is fixedly connected to the output end of the servo motor 4. A rack 6 is fixedly connected to the middle of the right end of the connecting frame 8, and the rack 6 meshes with the gear turntable 5. A keyway 7 is provided at the top of the housing 1, providing movement space for the gear turntable 5 and the rack 6. Ball screws 9 are fixedly connected to the front and rear of the right end of the connecting frame 8. Slots 10 are provided on the front and rear sides of the top of the housing 1, serving as components to fix the connecting frame 8 and prevent it from falling off. A [missing information - likely a component or part] is fixedly connected to the top of the right end of the connecting frame 8. The microprocessor 15 and the connecting frame 8 are both fixedly connected to the front and rear sides of the left end of the electric telescopic rod 11. The two electric telescopic rods 11 enable the lamp to illuminate from the front and rear. The left ends of the two electric telescopic rods 11 are rotatably connected to the lamp holder 12. The front side of the left end of the lamp holder 12 is fixedly connected to the distance sensor 13. The rear side of the left end of the lamp holder 12 is fixedly connected to the angle sensor 14. The left end of the lamp holder 12 is fixedly connected to the lamp cover 16, which serves as a protective component for the lamp. The top center of the base 2 is fixedly connected to the electric telescopic rod 24. The electric telescopic rod 24 can extend its length when the CNC machine tool needs to be inspected at a deeper location. The bottom end of the outer shell 1 is threadedly connected to the inspection cover 22. The bottom end of the base 2 is provided with a locking mechanism 3, which is used to fix the detector.
[0034] Specifically, by activating the distance sensor 13 and the angle sensor 14, the detector can automatically detect the location requiring maintenance and transmit the detected information back to the microprocessor 15, avoiding manual adjustment by the operator. At the same time, the servo motor 4 is activated, and through the meshing connection between the gear turntable 5 and the rack 6, the connecting frame 8 can move left and right as the servo motor 4 rotates. Furthermore, because there is a locking between the ball screw 9 and the slot 10, the connecting frame 8 is prevented from falling off. When the maintenance location is on the front or rear side of the housing 1, the microprocessor 15 controls the extension and retraction of the electric telescopic rod 11 based on the detection results, so that the left end of the lamp holder 12 faces the maintenance location, expanding the illumination range of the detector and avoiding uneven lighting and the problem of no light in corners.
[0035] Reference Figure 2 , Figure 3 and Figure 6The locking mechanism 3 includes a threaded hole 301, which is located at the bottom center of the base 2. A washer 302 is fixedly connected to the inner wall of the threaded hole 301. A bolt 303 is threadedly connected to the inner wall of the washer 302. A fixed plate 304 is threadedly connected to the middle of the outer wall of the bolt 303. Multiple sliding rods 306 are fixedly connected to the top of the fixed plate 304. Multiple sliding grooves 305 are provided inside the base 2. The multiple sliding rods 306 are slidably connected to the multiple sliding grooves 305 respectively. Multiple strong magnets 307 are fixedly connected to the bottom of the base 2.
[0036] Specifically, first, the fixed location is determined on the CNC machine tool. Then, the bolt 303 is unscrewed from the base 2 and the fixed plate 304 to release the mechanical connection between the base 2 and the fixed plate 304, thus releasing the positional constraint of the fixed plate 304. The fixed plate 304 and the sliding rod 306 are then pulled out. Next, the strong magnet 307 under the base 2 is attached to the fixed location on the machine tool to initially fix the position of the detector. The fixed plate 304 and the sliding rod 306 are inserted into the hole at the fixed location on the CNC machine tool, and the multiple sliding rods 306 are slid back into the slide grooves 305. Then, the bolt 303 is passed through the fixed plate 304 and screwed back into the threaded hole 301, which further enhances the stability of the fixation and overcomes the problem of being affected by the magnetic field when simply fixed by the strong magnet 307. In addition, the washer 302 can disperse the pressure when the CNC machine tool vibrates, protecting the threaded surface of the connection part.
[0037] Reference Figure 1 , Figure 2 and Figure 3Multiple heat-conducting pipes 20 are fixedly connected inside the lamp holder 12, and a heat dissipation pipe 21 is fixedly connected to the outside of the lamp holder 12. The multiple heat-conducting pipes 20 and the heat dissipation pipe 21 can prevent light decay of the light source after long-term use and extend the service life of the detector. A connecting post 23 is fixedly connected to the top of the electric telescopic rod 24. The top of the connecting post 23 is rotatably connected to the bottom of the inspection cover 22, so that the detector can directly hold the outer shell 1 to inspect CNC machine tools, or when the inspection position is deep, the electric telescopic rod 24 can be connected to extend the inspection distance, increasing the convenience of the device. Multiple refractive rings 17 are fixedly connected to the inner wall of the lamp cover 16. The multiple refractive rings 17 are all the same size as the inner wall of the lamp cover 16. The multiple refractive rings 17 can make the light reflect off the inner wall of the lamp cover 16. Refraction occurs over time, changing the direction of light propagation and further optimizing the lighting angle and range. A convex lens 18 is fixedly connected to the left side of the inner wall of the lampshade 16. The surface of the convex lens 18 is frosted, and the surface becomes rough after frosting. Light will undergo diffuse reflection on these rough surfaces, making the light passing through the convex lens 18 softer and avoiding strong light spots and glaring light patches. A dustproof hose 19 is fixedly connected to the left end of the connecting bracket 8. The other side of the dustproof hose 19 is fixedly connected to the right end of the lamp holder 12. A controller 25 is fixedly connected to the front side of the outer wall of the housing 1. The controller 25 is electrically connected to the servo motor 4, the electric telescopic rod 21, the distance sensor 13, the angle sensor 14, the microprocessor 15, and the electric telescopic rod 14.
[0038] Specifically, the heat generated by the light source is transferred to the heat dissipation pipe 21 through the heat conduction pipe 20, and then transferred to the outside through the heat dissipation pipe 21 to achieve heat dissipation of the light source. When the maintenance position of the CNC machine tool is deep, the detection length of the detector is extended by connecting the electric telescopic rod 24 to the maintenance cover 22, which enhances the applicability of the detector. When the light source is in use, multiple refraction rings 17 refract the light, so that the light scattered on the lamp cover 16 shines on the maintenance position. After being focused and diffused by the convex lens 18, the light at the maintenance point is bright but not dazzling, providing a more comfortable lighting environment.
[0039] Working principle: The mobile device is connected to the detector via Bluetooth. The distance sensor 13 and angle sensor 14 are activated by the mobile device or controller 25. The distance sensor 13 and angle sensor 14 detect the position to be detected and transmit the detection results to the microprocessor 15. The rotation angle of the light source is calculated and then the servo motor 4 is controlled to rotate, so that the gear turntable 5 rotates accordingly. Through the meshing connection with the rack 6, the position of the light source is changed. Under the coordination of the ball screw 9 and the slot 10, the direction of the light source rotates left and right around the top of the housing 1. Then, the two electric telescopic rods 11 are controlled to adjust the position of the light source back and forth, so that there is no situation where the inspection position is not illuminated, avoiding the existence of blind spots.
[0040] Furthermore, when the detector needs to be fixed on the data machine tool, by unscrewing the bolt 303 from the threaded hole 301 and the washer 302, the positional restriction of the fixed plate 304 and the sliding rod 306 is eliminated, allowing the fixed plate 304 and the sliding rod 306 to be smoothly pulled out from the slide groove 305 inside the base 2. When the base 2 of the detector is brought close to a suitable magnetic machine tool component, the strong magnet 307 is attracted to the machine tool, and the detector is fixed first. Then, the other side of the strong magnet 307 is fixed from the machine tool, and the sliding rod 306 is passed through the machine tool and slid into the slide groove 305. Finally, the bolt 303 is passed through the machine tool and fixed in the threaded hole 301 and the washer 302, further enhancing the stability of the fixation. The washer 302 also buffers the vibration generated when the data machine tool is working, reducing the damage to the bolt 303.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
