[0001] This utility model relates to the field of mechanical engineering technology, specifically to a self-made sensing and positioning device. Background Technology

[0002] The self-made inductive positioning device is mainly used for precise alignment of parts, calibration of tooling fixtures and tracking of assembly process progress in mechanical assembly. It is widely used in industries such as general machinery manufacturing, automotive parts assembly and small equipment assembly. Its core function is to capture the spatial position information of assembly parts or tooling through sensing components, assisting operators or automated equipment to complete high-precision assembly and reduce assembly deviation. Currently, commercial mechanical assembly sensing and positioning devices on the market mainly consist of industrial-grade displacement sensors, embedded control modules, data transmission interfaces, and positioning calibration software. They primarily collect real-time position data of assembled components through sensors, which is then analyzed and processed by the control module and fed back to the assembly system or operators. This achieves millimeter-level positioning accuracy, improves assembly efficiency, and ensures assembly consistency during mechanical assembly.

[0003] However, existing homemade inductive positioning devices are ineffective when encountering uneven parts or insensitive material feeding. Therefore, those skilled in the art provide a homemade inductive positioning device to solve the problems mentioned in the background art. Utility Model Content

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figures 1-6 As shown, this utility model provides a technical solution: a self-made sensing and positioning device, including a stop block 3, a slot 14 at one end of the stop block 3, a circular hole 4 on the outside of the stop block 3, a sensor 5 slidably connected to the inner wall of the circular hole 4, a wire 6 fixedly connected to the outside of the sensor 5, a stop post 7 fixedly connected to one end of the stop block 3, a long groove 13 inside the stop post 7, a positioning block 8 slidably connected to the inner wall of the long groove 13, a locking tongue 9 fixedly connected to one side of the outer wall of the positioning block 8, a stop plate 10 fixedly connected to the end of the locking tongue 9 away from the positioning block 8, a circular groove 12 inside the stop block 3, the stop plate 10 slidably connected to the inner wall of the circular groove 12, and a spring 11 inside the circular groove 12.

[0018] The abutment block 3 serves as the core support base of the device, providing an installation reference for each functional component; the slot 14 is used to cooperate with the positioning block 8 to achieve guidance and prevent the positioning block 8 from shifting during movement; the circular hole 4 provides an adjustable installation channel for the sensor 5, allowing the sensor 5 to slide along the inner wall of the circular hole 4 according to the positioning requirements during mechanical assembly, adjusting to the optimal sensing position. The sensor 5 can capture the position signal of the component to be assembled or the positioning mold in real time, and transmit the signal to the external control equipment through the wire 6 to achieve real-time feedback of position data; after the abutment column 7 is fixed with the abutment block 3, its internal long groove 13 serves as a positioning block. 8 provides sliding space, allowing the positioning block 8 to move flexibly along the long groove 13 according to the assembly conditions; the positioning block 8 forms a linkage structure with the abutment plate 10 through the locking tongue 9. When the positioning block 8 is subjected to the force of the part to be assembled or the positioning mold, it can drive the locking tongue 9 to push the abutment plate 10 to slide along the inner wall of the circular groove 12; the circular groove 12 not only provides a sliding trajectory for the abutment plate 10, but also plays a role in storing and limiting the spring 11. The spring 11 provides the reset power for the abutment plate 10 through its own elasticity, ensuring that the positioning block 8 can return to the initial positioning position when there is no external force intervention, thus ensuring the stability and repeatability of positioning during the assembly process.

[0019] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, a platform 1 is fixedly connected to the outside of the abutment block 3, and two limiting blocks 2 are fixedly connected to the top of the platform 1.

[0020] Platform 1 provides a stable mounting carrier for the entire sensing and positioning device, which can fix the entire device on the mechanical assembly station and prevent the device from shifting during assembly operations. Two limiting blocks 2 are symmetrically distributed on the top of platform 1. After being fixed to the outer wall of the abutment block 3, they can limit and constrain the abutment block 3 from the horizontal or vertical direction, preventing the abutment block 3 from shifting its position during long-term use or when subjected to assembly impact forces. This ensures the relative positional accuracy of components such as the circular hole 4 and the abutment post 7 on the abutment block 3, laying a stable structural foundation for the accurate sensing of the subsequent sensor 5 and the reliable positioning of the positioning block 8.

[0021] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the positioning block 8 is externally abutted against the positioning mold 15.

[0022] In the mechanical assembly process, the positioning mold 15 is used to fix the parts to be assembled, so that they maintain the preset assembly posture and position; when the positioning block 8 abuts against the outer wall of the positioning mold 15, the position information of the positioning mold 15 can be transmitted to the internal components of the device through physical contact, and different positioning molds 15 can be selected according to different products.

[0023] As one implementation method in this embodiment, please refer to Figure 3 As shown, one end of the spring 11 is fixedly connected to the inner wall of the circular groove 12, and the other end of the spring 11 is fixedly connected to the outside of the abutment plate 10.

[0024] Spring 11 forms an elastic support structure through the fixation at both ends. When the positioning block 8 is pushed by the positioning mold 15 or external assembly force, it will drive the abutment plate 10 to move into the circular groove 12 through the locking tongue 9. At this time, spring 11 is compressed and generates a reverse elastic force. When the external force disappears, spring 11 releases the elastic force and pushes the abutment plate 10 to slide in the opposite direction along the inner wall of the circular groove 12. Then, the locking tongue 9 drives the positioning block 8 to reset, so that the positioning block 8 can maintain stable contact with the positioning mold 15, ensuring the continuity of the positioning function in the entire assembly process and avoiding assembly interruption due to the displacement of the positioning block 8.

[0025] As one implementation method in this embodiment, please refer to Figures 3-5 As shown, the positioning block 8 is slidably connected to the inner wall of the slot 14.

[0026] The slot 14 and the long slot 13 in the abutment 7 cooperate with each other to provide bidirectional guiding constraint for the positioning block 8. When the positioning block 8 moves axially along the long slot 13, part of its structure is embedded in the slot 14 and slides along the inner wall of the slot 14. The slot 14 can limit the displacement of the positioning block 8 in the radial direction, avoid the positioning block 8 from shaking, tilting or rotating during the movement, and ensure that the positioning block 8 always moves along the preset trajectory, thereby ensuring the positional accuracy of the positioning block 8 when it abuts against the positioning mold 15 and reducing the assembly error caused by the offset of the positioning block 8.

[0027] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the outer wall of the abutment block 3 is fixedly connected to the outer wall of the limiting block 2.

[0028] The outer wall of the abutment block 3 and the limiting block 2 are fixed to form a double fixing structure. The limiting block 2 can not only protect the edge of the abutment block 3, but also provide support for the abutment block 3 from the side, preventing the abutment block 3 from deforming or shifting when it is subjected to the force transmitted by the positioning block 8 or the vibration generated when the sensor 5 is working.

[0029] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the abutment 10 abuts against the inner wall of the circular groove 12.

[0030] The outer wall of the abutment plate 10 fits tightly against the inner wall of the circular groove 12. The inner wall of the circular groove 12 can precisely restrict the sliding direction of the abutment plate 10, preventing the abutment plate 10 from jamming, shifting, or tilting during movement, and ensuring the smooth movement of the abutment plate 10, locking tongue 9, and positioning block 8. At the same time, the contact relationship between the abutment plate 10 and the inner wall of the circular groove 12 can also prevent the spring 11 from shifting laterally during compression or stretching, ensuring that the spring 11 always exerts force along the axial direction, thereby ensuring that the reset action of the abutment plate 10 is stable and reliable, and providing continuous and stable elastic support for the precise positioning of the positioning block 8.

[0031] Working principle: When this self-made inductive positioning device is working, platform 1 serves as a stable mounting carrier for the entire device. The two limiting blocks 2 fixed at its top can limit and constrain the abutment block 3, preventing the abutment block 3 from shifting during use, thereby ensuring the relative positional accuracy of the components on the abutment block 3. The abutment block 3, as the core support base, has a slot 14 at one end that cooperates with the long groove 13 inside the abutment post 7 fixed at one end, providing bidirectional guiding constraint for the positioning block 8. This allows the positioning block 8 to slide stably along the inner walls of the long groove 13 and the slot 14. The positioning block 8 abuts against the positioning mold 15 to obtain the positioning reference. When the positioning block 8 is subjected to the positioning mold 15 or external assembly force, it will drive the locking tongue 9 fixed on one side of the outer wall to push the locking tongue 9 away from the abutment plate 10 fixed at one end of the positioning block 8. The abutment plate 10 slides on the inner wall of the circular groove 12 inside the abutment block 3, while compressing the spring 11 inside the circular groove 12. When the external force disappears, the spring 11 releases its elasticity and pushes the abutment plate 10 to reset, which in turn drives the positioning block 8 to reset through the locking tongue 9, ensuring that the positioning block 8 continues to stably abut against the positioning mold 15. At the same time, the circular hole 4 on the outside of the abutment block 3 provides an adjustable installation channel for the sensor 5 that slides on the inner wall. The sensor 5 can be adjusted to the optimal sensing position along the circular hole 4 to capture the position signal of the part to be assembled or the positioning mold 15 in real time, and transmit the signal to the external control device through the externally fixed wire 6 to realize real-time feedback of position data. All components work together to ensure the stability, accuracy and continuity of positioning during mechanical assembly.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
