Description

Technical Field

[0001] This utility model relates to the field of sensor processing technology, and in particular to a device for polishing burrs in the inner cavity of a vehicle sensor housing. Background Technology

[0002] Automotive sensors include sensing elements, conversion elements, measurement circuits, sensor chips, and housings. The burr polishing process of the inner cavity of the sensor housing directly affects the sensor's sealing performance and signal accuracy. Furthermore, due to the different types and application scenarios, automotive sensors have a variety of housing structures, including complex curvature surface structures and irregular shapes.

[0003] In existing technologies, the polishing process for sensor housings often involves mechanically clamping and fixing the sensor housing, and using a motor to drive the grinding block to complete the automated polishing. However, the grinding head structure is rigid and fixed, which cannot adapt to the inner cavity surfaces with different curvatures, resulting in uneven polishing of complex housings. In addition, for the frequent loading and unloading of sensor housings, the processing method of operating separately from the polishing unit will cause process interruptions and lengthen the cycle, affecting the processing efficiency of automotive sensors. Therefore, a solution is proposed to address the aforementioned technical deficiencies. Utility Model Content

[0004] The purpose of this invention is to provide a burr polishing device for the inner cavity of a vehicle sensor housing, in order to solve the problems of the rigid fixed structure of the grinding head being unable to adapt to the curved surfaces of inner cavities with different curvatures and the discontinuous loading and unloading of materials.

[0006] Preferably, the polishing mechanism includes a drive rod rotatably disposed in a polishing seat, polishing brushes are evenly distributed on the outer side of the drive rod, and a polishing disc is installed at the front end of the drive rod.

[0008] Preferably, the outer side of the mating ring matches the inner side of the outer sleeve plate, and the inner side of the mating ring matches the outer side of the hollow fixed cylinder.

[0009] Preferably, a telescopic rod is provided on the side of the sensor body away from the torsion cylinder, and the inner end of the telescopic rod is connected to a push-and-retract suction cup that fits against the outer wall of the sensor body.

[0010] Preferably, the hollow fixed cylinder has a horizontal opening in the feeding direction of the conveyor belt, and a protective sleeve is hinged to the opening of the hollow fixed cylinder.

[0011] Preferably, when the spring is not subjected to external force, it supports the torsion cylinder and the mating ring in a horizontal coaxial state.

[0012] The beneficial effects of this utility model are: (1) On the one hand, this utility model uses a polishing mechanism that can be twisted to complete the adaptation processing of automotive sensor housings of different sizes during the polishing process. On the other hand, the unloading and loading of the polished sensor housing are carried out continuously, which can effectively improve the sensor polishing processing efficiency. With the combination of the two, when removing burrs from the inner cavity of the sensor housing, the adaptive polishing mechanism can complete the effective polishing of the inner wall structure of different curvature surfaces, thereby improving its polishing efficiency.

[0015] 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.

[0016] Example 1: This example is used to solve the problem that the rigid fixed structure of the grinding head cannot adapt to the curved surfaces of the inner cavity with different curvatures.

[0017] Please see Figure 1 - Figure 5 As shown, this embodiment is a burr polishing device for the inner cavity of a vehicle sensor housing, including a substrate 1 and a sensor body 9. A conveyor belt 12 is arranged above the substrate 1, and an outer sleeve 2 is installed at the conveying end of the conveyor belt 12. A hollow fixing cylinder 7 is arranged in the outer sleeve 2, and the sensor body 9 is arranged in the hollow fixing cylinder 7. A torsion cylinder 3 is installed on one side of the hollow fixing cylinder 7, and a polishing seat 4 is arranged at the front end of the torsion cylinder 3. A polishing mechanism corresponding horizontally to the sensor body 9 is arranged in the polishing seat 4. The hollow fixing cylinder 7 is used to intermittently insert the sensor body 9. When the position of the hollow fixing cylinder 7 is changed, the position of the torsion polishing mechanism is adapted to perform all-round polishing operation with the inner wall of the sensor body 9, so as to ensure the complete removal of burrs in the inner cavity of the vehicle sensor housing.

[0018] The polishing mechanism includes a drive rod 14 rotatably disposed in the polishing seat 4, polishing brush plates 15 evenly distributed on the outer side of the drive rod 14, a polishing disc 16 installed at the front end of the drive rod 14, a motor 13 whose output end is connected to the drive rod 14 is embedded in the torsion cylinder 3, a number of springs 6 are connected to the front end of the polishing seat 4, and a mating ring 5 sleeved on the front end of the number of springs 6 is installed on the front end of the number of springs 6. The actual operation of the polishing mechanism is as follows: the motor 13 drives the polishing brush plate 15 and the polishing disc 16 to rotate through the drive rod 14. After the sensor body 9 moves and is fitted outside the polishing brush plate 15 and the polishing disc 16, the burrs inside the sensor body 9 can be removed in all directions by manually rotating and twisting the cylinder 3. The outer side of the mating ring 5 matches the inner side of the outer sleeve plate 2, and the inner side of the mating ring 5 matches the outer side of the hollow fixed cylinder 7; the flexible support effect of the spring 6 and the docking action of the mating ring 5 are used to achieve stable support when polishing is not performed, and can ensure accurate guidance of the sensor body 9 when following the hollow fixed cylinder 7 to the outer sleeve of the polishing mechanism.

[0019] The basic principle of this utility model: Please refer to... Figure 1 - Figure 3As shown, the polishing process for automotive sensors employs a feeding and polishing conversion method to achieve multi-size adaptability polishing. Specifically, on one hand, a torsion-enabled polishing mechanism is used during the polishing process to adapt the sensor housings of different sizes. On the other hand, the unloading and loading of the polished sensor housings are performed continuously, which effectively improves the efficiency of sensor polishing. With the combination of these two methods, the adaptability polishing mechanism effectively polishes the inner wall structures of curved surfaces with different curvatures when removing burrs from the inner cavity of the sensor housing, thereby improving its polishing efficiency.

[0020] Example 2: This example is used to solve the problem of discontinuous loading and unloading during the polishing process of automotive sensors.

[0021] Please see Figure 1 , Figure 4 - Figure 5 As shown, this embodiment of a burr polishing device for the inner cavity of a vehicle sensor housing includes a telescopic rod 11 disposed on the side of the sensor body 9 away from the torsion cylinder 3. The inner end of the telescopic rod 11 is connected to a push-and-retract suction cup 10 that fits against the outer wall of the sensor body 9. Based on Embodiment 1, regarding how to achieve continuous loading and unloading of the sensor housing, an electric push rod is disposed outside the telescopic rod 11. The electric push rod drives the telescopic rod 11 to move horizontally, so that the push-and-retract suction cup 10 directly contacts the sensor body 9. The active adsorption of the push-and-retract suction cup 10 completes the pushing or pulling of the sensor body 9 into the torsion cylinder 3. During this process, the polishing preparation of the sensor body 9 is achieved. The hollow fixed cylinder 7 has a horizontal opening in the feeding direction of the conveyor belt 12. A protective sleeve 8 is hinged to the opening of the hollow fixed cylinder 7. When the spring 6 is not subjected to external force, the supporting torsion cylinder 3 and the mating ring 5 are in a horizontal coaxial state. The protective sleeve 8 is driven to rotate by the drive motor A embedded in the hollow fixed cylinder 7, realizing the intermittent opening and closing of the opening on the hollow fixed cylinder 7. In addition, the conveyor belt 12 is pre-set with a fixing clamp for the sensor body 9. The sensor body 9 can be automatically retracted when it is detached from the conveyor belt 12, which facilitates feeding onto the conveyor belt 12 and feeding into the hollow fixed cylinder 7. For the feeding and feeding process, the sensor body 9 is continuously and intermittently fed by the conveyor belt 12, and the sensor body 9 is intermittently inserted into the hollow fixed cylinder 7 by the intermittent opening of the protective sleeve 8.

[0022] In summary, this invention, on the one hand, utilizes a torsion-enabled polishing mechanism during the polishing process to achieve adaptability processing for automotive sensor housings of different sizes; on the other hand, the unloading and loading of the polished sensor housings are performed continuously, effectively improving the sensor polishing efficiency. The combination of these two aspects enables the effective polishing of inner wall structures with different curvatures by the adaptable polishing mechanism when removing burrs from the inner cavity of the sensor housing, thereby improving its polishing efficiency.
