[0002] The field of machining technology is one of the core areas of manufacturing. It mainly studies the technology system that processes raw materials into mechanical parts or finished products with specific shapes, sizes, precision and surface quality through various machining methods. In the grinding process of mechanical parts, the grinding wheel is the core grinding tool, and its surface condition directly affects the machining accuracy and efficiency.

[0003] Regarding existing related technologies, the inventors believe that the following defects often exist: In most existing automatic dressing devices for grinding wheels in the grinding of mechanical parts, the sensors lack effective protective structures. Impurities generated during grinding can easily adhere to the detection end or enter the internal circuit, leading to signal interference, increased detection errors, and even sensor failure, thus affecting the reliability of the automatic dressing system. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing automatic dressing devices for grinding wheels in the grinding of mechanical parts have the disadvantage that most of them lack effective protective structures for the sensors, making them susceptible to signal interference and increased detection errors due to the influence of grinding impurities. Therefore, we propose an automatic dressing device for grinding wheels in the grinding of mechanical parts.

[0005] To achieve the above objectives, this application adopts the following technical solution: an automatic dressing device for grinding wheels in the grinding of mechanical parts, comprising a processing table, a support frame fixed to the bottom of the processing table, a frame fixed to the top of the processing table, a protective door rotatably connected to one side of the frame via a hinge, a fixing plate fixed to one side of the frame, a lead screw rotatably connected to the bottom end of the fixing plate, the other end of the lead screw rotatably connected to the processing table, a first motor provided at the top of the fixing plate, the output end of the first motor fixed to one end of the lead screw, a movable seat threadedly connected to the surface of the lead screw, a dressing component fixed to one side of the movable seat, and a dressing component fixed to one side of the frame. A second motor is fixed, and a trimming shaft is fixed to the output end of the second motor. A laser displacement detection device is fixed inside the frame. The laser displacement detection device is unidirectionally electrically connected to the first motor. One end of the laser displacement detection device is rotatably connected to a transparent protective shell via a rotating shaft. An upper shell is fixed to one end of the transparent protective shell, and a lower shell is fixed to the other end of the laser displacement detection device. A lower protrusion is provided inside the lower shell. A pull rod is fixed to one end of the lower protrusion. An upper protrusion is slidably connected to one side of the lower protrusion. An elastic locking block is fixed to one side of the upper protrusion. A T-slot is provided inside the upper shell to cooperate with the elastic locking block.

[0006] Preferably, a first guide block is fixed to one side of the lower protrusion, and a first guide groove is provided inside the lower housing to cooperate with the first guide block.

[0007] Preferably, one end of the lower protrusion is fixed with a spring, and the other end of the spring is fixed to the lower housing.

[0008] Preferably, a second guide block is fixed at both ends of the upper protrusion, and a second guide groove is provided inside the lower housing to cooperate with the second guide block.

[0012] The technical effects and advantages of this utility model are as follows: In this invention, through the above process, the transparent protective shell forms a physical barrier for the laser displacement detection device, which can effectively prevent impurities such as metal chips, dust and coolant generated during the grinding process from directly contacting the core components of the laser displacement detection device. This avoids impurities adhering to the detection end of the laser displacement detection device or entering the internal circuit, preventing detection errors caused by signal interference, light path obstruction or circuit short circuit, ensuring that the grinding wheel status parameters can always be accurately captured, and providing reliable feedback data for the automatic dressing system.

[0013] In this invention, a fan at the top of the frame, connected to an exhaust port via a connecting pipe, can quickly extract metal shavings, dust, and other impurities generated during the grinding process. These impurities are then collected in a collection box on the other side of the fan. This not only keeps the inside of the frame and the processing environment clean and reduces the wear of equipment parts by dust, but also reduces the impact of dust on the health of operators, meeting the requirements for environmentally friendly production.

[0016] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0017] Reference Figures 1-5As shown, this utility model provides a technical solution: an automatic dressing device for grinding wheels in the grinding of mechanical parts, including a processing table 1, a support frame 2 fixed to the bottom of the processing table 1, a frame 3 fixed to the top of the processing table 1, a protective door 4 rotatably connected to one side of the frame 3 via a hinge, a fixing plate 5 fixed to one side of the frame 3, a lead screw 6 rotatably connected to the bottom end of the fixing plate 5, the other end of the lead screw 6 rotatably connected to the processing table 1, a first motor 7 set at the top of the fixing plate 5, the output end of the first motor 7 fixed to one end of the lead screw 6, a movable seat 8 threadedly connected to the surface of the lead screw 6, a dressing component 9 fixed to one side of the movable seat 8, a second motor 10 fixed to one side of the frame 3, a dressing shaft 11 fixed to the output end of the second motor 10, a laser displacement detection device 12 fixed inside the frame 3, the laser displacement detection device 12 being unidirectionally electrically connected to the first motor 7, and one end of the laser displacement detection device 12 being rotatably connected via a rotating shaft. A transparent protective shell 13 is attached, with an upper shell 14 fixed to one end of the transparent protective shell 13 and a lower shell 15 fixed to the other end of the laser displacement detection device 12. A lower protrusion 16 is provided inside the lower shell 15, and a pull rod 17 is fixed to one end of the lower protrusion 16. An upper protrusion 18 is slidably connected to one side of the lower protrusion 16, and an elastic locking block 19 is fixed to one side of the upper protrusion 18. A T-shaped groove 20 that cooperates with the elastic locking block 19 is opened inside the upper shell 14. A first guide block 21 is fixed to one side of the lower protrusion 16, and a first guide groove 22 that cooperates with the first guide block 21 is opened inside the lower shell 15. Second guide blocks 24 are fixed to both ends of the upper protrusion 18, and a second guide groove 25 that cooperates with the second guide block 24 is opened inside the lower shell 15. A sealing block 28 is fixed to one side of the transparent protective shell 13, and a sealing groove 29 that cooperates with the sealing block 28 is opened to one side of the laser displacement detection device 12.

[0018] Specifically: Through the unidirectional electrical connection between the laser displacement detection device 12 and the first motor 7, the grinding wheel status can be monitored in real time and a signal can be fed back to the first motor 7, driving the lead screw 6 to rotate and move the moving seat 8 and dressing part 9 along a precise trajectory. At the same time, in conjunction with the dressing shaft 11 driven by the second motor 10, the grinding wheel dressing operation is completed from multiple angles, greatly improving dressing accuracy and efficiency. In addition, the protective door 4 on one side of the frame 3 can effectively block the flying debris during grinding, ensuring a safe operating environment. The transparent protective shell 13 is rotated by a rotating shaft on one side of the laser displacement detection device 12 to make it fit. Then, the lower protrusion 16 is moved by pushing the pull rod 17. The inclined surface on one side of the lower protrusion 16 pushes the upper protrusion 18 to move towards the upper shell 14. At the same time, with the coordinated cooperation of the first guide block 21 and the first guide groove 22 and the second guide block 24 and the second guide groove 25, the stability of the lower protrusion 16 and the upper protrusion 18 during movement is ensured, and the deviation is avoided. In this process, the two ends of the top of the elastic block 19 are first squeezed by the inclined surface inside the T-slot 20, and smoothly enter the interior of the T-slot 20 through the squeeze, thereby completing the connection between the laser displacement detection device 12 and the transparent protective shell 13. The sealing block 28 and the sealing groove 29 fit tightly together to form a good sealing and protective structure, which can effectively isolate impurities such as dust and coolant generated during grinding, and prevent them from entering the interior of the laser displacement detection device 12 and affecting the detection accuracy. Through the above process, the transparent protective shell 13 forms a physical barrier for the laser displacement detection device 12, which can effectively prevent metal chips, dust and coolant generated during grinding from directly contacting the core components of the laser displacement detection device 12. This avoids impurities adhering to the detection end of the laser displacement detection device 12 or entering the internal circuit, and prevents detection errors caused by signal interference, light path obstruction or circuit short circuit, ensuring that the grinding wheel state parameters can always be accurately captured, providing reliable feedback data for the automatic dressing system.

[0019] Reference Figure 5 As shown in this embodiment: one end of the lower protrusion 16 is fixed with a spring 23, the other end of the spring 23 is fixed with the lower housing 15, and both ends of the upper housing 14 are slidably connected with push rods 26, one end of the push rod 26 is fixed with a push plate 27.

[0020] Specifically: The lower protrusion 16 is fixed to the lower housing 15 by a spring 23 at one end. When the pull rod 17 is pulled to move the lower protrusion 16, the spring 23 undergoes elastic deformation to store potential energy. After the pull rod 17 is released, the restoring force of the spring 23 can drive the lower protrusion 16 to automatically return to its original position, ensuring that the elastic locking block 19 of the upper protrusion 18 is tightly engaged in the T-slot 20, realizing the quick connection between the upper housing 14 and the lower housing 15. At the same time, the push rod 26 inside the upper housing 14 cooperates with the push plate 27. Pushing the push rod 26 can drive the push plate 27 to squeeze the two ends of the elastic locking block 19. Then, the rebound force of the spring 23 is used to drive the lower protrusion 16 to move. The inclined surface of the lower protrusion 16 pulls the upper protrusion 18 to move, causing it to drive the elastic locking block 19 to disengage from the T-slot 20, realizing convenient separation. The operation is very simple, and it is also convenient for operators to maintain and replace the laser displacement detection device 12.

[0021] Reference Figure 3 As shown in this embodiment: a fan 30 is fixed to the top of the frame 3, a connecting pipe 31 is fixed to one side of the fan 30, one end of the connecting pipe 31 extends into the interior of the frame 3, an exhaust port 32 is fixed to one end of the connecting pipe 31, and a collection box 33 is fixed to the other side of the fan 30.

[0022] Specifically: The fan 30 at the top of the frame 3, connected to the exhaust port 32 via the connecting pipe 31, can quickly extract metal shavings, dust and other impurities generated during the grinding process. These impurities are then collected in a collection box 33 on the other side of the fan 30. This not only keeps the inside of the frame 3 and the processing environment clean and reduces the wear of equipment parts by dust, but also reduces the impact of dust on the health of operators, meeting the requirements of environmentally friendly production.

[0023] Working principle: The user can monitor the grinding wheel status in real time and send a signal back to the first motor 7 via a unidirectional electrical connection between the laser displacement detection device 12 and the first motor 7. This drives the lead screw 6 to rotate, causing the moving seat 8 and dressing component 9 to move along a precise trajectory. Simultaneously, in conjunction with the dressing shaft 11 driven by the second motor 10, the grinding wheel dressing operation is completed from multiple angles, significantly improving dressing accuracy and efficiency. In addition, the protective door 4 on one side of the frame 3 can effectively block the flying debris during grinding, ensuring a safe operating environment. The transparent protective shell 13 is rotated by a rotating shaft on one side of the laser displacement detection device 12 to fit it, and then pushed... The movable lever 17 drives the lower protrusion 16 to move. The inclined surface on one side of the lower protrusion 16 pushes the upper protrusion 18 to move towards the upper housing 14. At the same time, with the coordinated cooperation of the first guide block 21 and the first guide groove 22, and the second guide block 24 and the second guide groove 25, the stability of the lower protrusion 16 and the upper protrusion 18 during movement is ensured, and the deviation is avoided. During this process, the two ends of the top of the elastic block 19 are first squeezed by the inclined surface opened inside the T-shaped groove 20. Through the squeeze, it smoothly enters the interior of the T-shaped groove 20, thereby completing the connection between the laser displacement detection device 12 and the transparent protective shell 13.

[0024] 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.
