Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a sensor fine-tuning device. Background Technology

[0002] A sensor is a detection device that can sense the information being measured and transform the sensed information into an electrical signal or other required form of information output according to a certain rule, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

[0003] Currently, most sensor installation methods lack fine-tuning mechanisms, making it difficult to precisely position the sensor at the optimal detection location. This not only affects the initial installation accuracy of the sensor but also limits its stability and reliability during long-term operation. Because high-precision position and angle adjustments are not possible, the sensor may fail to accurately align with the target object or signal source, introducing systematic errors. This is particularly detrimental to applications requiring high-precision measurements (such as precision manufacturing, medical equipment, and aerospace), potentially leading to inaccurate data acquisition and consequently impacting the performance of decision-making and control systems.

[0004] Therefore, a sensor fine-tuning device was specially designed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the present invention provides a sensor fine-tuning device.

[0006] A sensor fine-tuning device, comprising:

[0007] The mounting plate serves as a mounting carrier and is vertical in shape. A vertical mounting groove is opened on one side of the inside of the mounting plate, and a positioning rail is set in the middle of the side of the mounting plate.

[0008] The photoelectric sensor is slidably mounted on the positioning rail on the side of the mounting plate. Symmetrical fasteners are threaded through the inner side of the photoelectric sensor. The through part of the fastener extends into the mounting groove and the end is outward. The outward end of the fastener is threaded with a locking member that abuts against the other side of the mounting plate.

[0009] The fixing plate, rotatably mounted at the bottom of the mounting plate, serves as another mounting carrier. It is curved in shape, with reinforcing ribs between its two end faces at the bend. A protective shell is installed at the rotatable point of the fixing plate and the mounting plate, with a scale sleeve covering the outside of the protective shell. A shaft is rotatably mounted in the center of the protective shell, with a spur gear mounted outside the shaft. A protrusion is located on the outside of the protective shell, with a threaded screw threaded onto it. A knob is located at the outward-facing end of the screw, and a rack is rotatably mounted at the end of the screw facing the spur gear. The rack meshes and locks with the teeth of the spur gear.

[0010] As an improvement to the above solution, it also includes a lifting block, a guide rail, and limit screws. A guide rail is provided in the middle of the photoelectric sensor, and a lifting block is slidably arranged on the guide rail. Limit screws are threaded through the left and right sides of the lifting block, and the ends of the limit screws abut against the outside of the guide rail.

[0011] As an improvement to the above scheme, a scale plate is also included, with a scale plate provided on the middle side wall of the photoelectric sensor.

[0012] As an improvement to the above solution, it also includes a reinforcing member, a fixing seat, and a slide rail. Symmetrical reinforcing members are threaded through the lower part of the fixing plate. A fixing seat is threaded on the outside of the through end of the reinforcing member. A slide rail is slidably sleeved on the outside of the fixing seat. The slide rail is slidably connected to the roller structure of the reinforcing member itself.

[0013] As an improvement to the above solution, it also includes wedge-shaped washers, with two wedge-shaped washers that engage with each other between the upper part of the reinforcement and the top surface of the lower part of the fixing plate.

[0014] As an improvement to the above solution, it also includes rubber ring one and rubber ring two. Rubber ring one is fitted between the lower wedge-shaped washer and the lower top surface of the fixing plate, and rubber ring two is provided between the fixing seat and the lower bottom surface of the fixing plate.

[0015] The beneficial effects of this utility model are as follows: 1. The transmission system composed of screw, rack and pinion makes the angle adjustment of the mounting plate simple and precise. The mounting plate can be unlocked and rotated freely by turning the knob, ensuring that each adjustment is controllable and repeatable. The design of the fasteners and locking parts takes into account the maintenance and calibration work that may be needed later. Users can loosen or tighten these components as needed to make necessary adjustments.

[0016] 2. The combination of the fixing plate and the reinforcing ribs provides strong structural support, ensuring that the entire device remains stable even during adjustment, avoiding unnecessary displacement or deformation. The presence of the scale plate and scale sleeve makes it convenient for users to record the data of each adjustment, providing a reference for future maintenance.

[0017] 3. The wedge-shaped washer design significantly improves the friction between the upper part of the reinforcement and the lower top surface of the fixing plate. When the reinforcement is tightened, the two wedge-shaped washers interlock to form a tight contact surface, preventing the reinforcement from loosening and ensuring a more stable and reliable connection between the fixing plate and the mounting plate. The application of the reinforcement and its rubber rings one and two not only enhances the sealing between the components but also plays a role in shock absorption, reducing the impact of external vibrations on the accuracy of the photoelectric sensor.

[0018] 4. The lifting block helps the photoelectric sensor establish a connection with other external devices, improving the system's adaptability and meeting the needs of different application scenarios; the sliding connection between the slide rail and the roller structure of the reinforcement provides additional support, enhances the connection strength between the fixed plate and the mounting plate, and ensures the stability of the system.

[0019] 5. Through the roller structure on the slide rail and fixed base, as well as the mobility of the photoelectric sensor on the positioning rail, users can make rough and fine adjustments to the photoelectric sensor in the horizontal direction before installation to ensure that it is in the optimal detection position. The design of the lifting block allows for vertical height adjustment, further enhancing the flexibility and accuracy of the adjustment. Attached Figure Description

Detailed Implementation

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0028] Example: A fine-tuning device for a sensor, such as Figures 1-5 As shown, it includes:

[0029] Mounting plate 1 serves as a mounting carrier, is vertical, and provides a stable platform to ensure that other components can be installed and operated correctly. A vertical mounting groove is opened on one side of the interior of mounting plate 1, and a positioning rail 101 is provided in the middle of the side of mounting plate 1.

[0030] The photoelectric sensor 2 is slidably mounted on the positioning rail on the side of the mounting plate 1. Symmetrical fasteners 3 are threaded through the inner side of the photoelectric sensor 2. The through part of the fastener 3 extends into the mounting groove and the end is outward. The outward end of the fastener 3 is threaded with a locking member 4 that abuts against the other side of the mounting plate 1. This ensures the firmness of the photoelectric sensor 2 on the positioning rail. The user can slightly loosen the fasteners 3 and the locking member 4 to allow the photoelectric sensor 2 to slide within a small range on the positioning rail, thereby achieving more precise position adjustment.

[0031] A fixed plate 5, rotatably mounted at the bottom of the mounting plate 1, serves as another mounting carrier. Its overall curved shape enhances the structural stability. Reinforcing ribs 51 are provided between the two end faces of the bent portion of the fixed plate 5, strengthening its structural strength and preventing deformation. A protective shell 6 is provided at the rotatable joint between the fixed plate 5 and the mounting plate 1. A scale sleeve 61 is fitted over the protective shell 6 for precisely measuring and setting the rotation angle, ensuring the adjusted angle meets expectations and guaranteeing that each adjustment is controllable and repeatable. A rotating shaft 7 is located in the center of the protective shell 6, allowing free rotation and driving a spur gear 8 to rotate, thus adjusting the angle of the mounting plate 1. The mounting plate 5 is connected to the rotating part at the bottom of the mounting plate 1 via the shaft 7 and the protective shell 6, ensuring that the mounting plate 1 can rotate freely. A spur gear 8 is provided on the outside of the shaft 7, and a protrusion is provided on the outside of the protective shell 6. A screw 10 is provided with an internal thread on the protrusion. A knob 11 is provided on the outward end of the screw 10 for manual operation by the user to adjust the angle. A rack 9 is provided on the end of the screw 10 facing the spur gear 8. The rack 9 and the teeth of the spur gear 8 form a meshing lock. When the screw 10 moves linearly, it drives the rack 9 to move towards the protrusion to release or establish the locking state between the spur gear 8 and the rack 9, realizing the unlocking and locking of the angle adjustment.

[0032] like Figure 1 and Figure 2 As shown, it also includes a lifting block 201, a guide rail 202, and a limiting screw 203. The guide rail 202 is provided in the middle of the photoelectric sensor 2, and the lifting block 201 is slidably arranged on the guide rail 202. The lifting block 201 provides an additional height adjustment function to help the photoelectric sensor 2 better connect with external equipment. The lifting block 201 is threaded through on both sides of the left and right sides and the limiting screw 203 is provided. The end of the limiting screw 203 abuts against the outside of the guide rail 202. The limiting screw 203 is used to fix the position of the lifting block 201 to ensure its stable operation at different heights.

[0033] like Figure 1As shown, it also includes a scale plate 204. The scale plate 204 is provided on the middle side wall of the photoelectric sensor 2, allowing users to intuitively read and record the specific position of the photoelectric sensor 2, which is convenient for verification or adjustment record saving after adjustment.

[0034] like Figure 1 , Figure 5 and 6 As shown, it also includes a reinforcing member 12, a fixing seat 16, and a slide rail 17. The lower part of the fixing plate 5 is threaded with symmetrical reinforcing members 12, which serve to fix the plate and enhance the connection strength between the fixing plate 5 and the mounting plate 1. The external thread of the reinforcing member 12 is provided with a fixing seat 16, and the external sliding sleeve of the fixing seat 16 is fitted with a slide rail 17. The slide rail 17 is slidably connected to the roller structure of the reinforcing member 12, providing additional support and ensuring the stability of the system.

[0035] like Figure 1 , Figure 5 and 6 As shown, it also includes wedge-shaped washers 13. Two wedge-shaped washers 13 are fitted between the upper part of the reinforcing member 12 and the top surface of the lower part of the fixing plate 5 and engage with each other. Through the engaging structure, they are in close contact with the reinforcing member 12 and the fixing plate 5, which enhances the friction and stability of the connection.

[0036] like Figure 1 , Figure 5 and 6 As shown, it also includes rubber ring 14 and rubber ring 15. Rubber ring 14 is fitted between the lower wedge-shaped washer 13 and the lower top surface of the fixing plate 5, which increases the sealing and shock absorption effect and reduces the impact of external vibration on the accuracy of the photoelectric sensor 2. Rubber ring 15 is provided between the fixing seat 16 and the lower bottom surface of the fixing plate 5 to further enhance the sealing and shock absorption effect and ensure the long-term stability and reliability of the system.

[0037] In use, first, firmly install the slide rail 17 on the designated mounting point. Next, place the mounting base 16 with the roller structure at one end of the slide rail 17, aligning its guide groove with the slide rail 17. At the same time, use screws or other fasteners 3 to initially fix the mounting base 16 to one end of the slide rail 17, but do not tighten it completely to allow for subsequent fine-tuning of the position. Then, place the mounting plate 1 on the mounting base 16, so that the rotating part at the bottom of the mounting plate 1 is adapted to the mounting base 16. The mounting plate 5 is supported by the reinforcing rib 51, which enhances the overall stability of the structure and prevents unnecessary displacement or deformation during adjustment. The reinforcing member 12 in the lower part of the mounting plate 5 not only plays a fixing role, but also increases the stability and sealing of the structure through (rubber ring 14 and rubber ring 2 15), reducing the impact of vibration on the accuracy of the photoelectric sensor 2.

[0038] The photoelectric sensor 2 on the mounting plate 1 can move horizontally via the positioning rail 101. Before installing the photoelectric sensor 2, the user can adjust its position as needed to achieve the optimal detection position. After the position of the photoelectric sensor 2 is determined, the photoelectric sensor 2 is fixed to the positioning rail 101 using fasteners 3, and further locked in the mounting slot of the mounting plate 1 using locking pieces 4 to prevent the photoelectric sensor 2 from moving in subsequent operations. If more precise adjustment is required, the user can slightly loosen the fasteners 3 and locking pieces 4 to allow the photoelectric sensor 2 to slide within a small range on the positioning rail 101, thereby achieving more precise position adjustment. In addition, the scale plate 204 allows the user to intuitively read and record the specific position of the photoelectric sensor 2, which is convenient for verification after adjustment or for saving adjustment records.

[0039] If the photoelectric sensor 2 needs to establish communication with other external devices, the lifting block 201 can be used as an auxiliary mounting component. The lifting block 201 not only helps the photoelectric sensor 2 to better interface with external devices, but also provides an additional height adjustment function. By loosening the limit screw 203 inside the lifting block 201, the height of the lifting block 201 can be adjusted, thereby changing the height of the photoelectric sensor 2 relative to the mounting plate 1. After the adjustment is completed, the limit screw 203 is tightened again to fix the new position, ensuring the stable operation of the photoelectric sensor 2 at different heights. The fixed base 16 is covered with a slide rail 17. The slide rail 17 is slidably connected to the roller structure of the reinforcing component 12, providing additional support and enhancing the connection strength between the fixed plate 5 and the mounting plate 1, ensuring the stability of the system.

[0040] When the angle of the mounting plate 1 needs to be adjusted, first turn the knob 11 to make the screw 10 move linearly within the protrusion. This action will drive the rack 9 to move synchronously, thereby releasing the meshing lock between the spur gear 8 and the rack 9. At this time, the mounting plate 1 can rotate freely, and the shaft 7 rotates with the rotation of the mounting plate 1, which in turn drives the spur gear 8 to rotate. The protective shell 6 rotates with the spur gear 8, and finally the angle of the mounting plate 1 is adjusted. Throughout the process, the scale sleeve 61 on the outside of the protective shell 6 is used to accurately measure and set the rotation angle to ensure that the adjusted angle meets the expectations. The presence of the scale sleeve 61 allows the user to intuitively monitor the angle change, ensuring that each adjustment is controllable and repeatable.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
