Description

Technical Field

[0001] This utility model relates to locking devices, and more particularly to a pin locking device. Background Technology

[0002] Thickness inspection is a common and crucial process in fields such as machinery manufacturing, precision machining, and food processing. Traditional thickness inspection devices typically employ complex mechanical structures or electronic sensors. While these can meet certain accuracy requirements, they suffer from drawbacks such as complex structures, high manufacturing costs, and difficult maintenance. Furthermore, traditional devices are prone to issues like asynchronous slider movement, jamming, or misalignment during inspection, affecting the accuracy and stability of the measurement.

[0003] To address the aforementioned problems, some improvements have been proposed in the prior art. For example, a linear slide and slider structure are used to simplify the device design, and synchronous movement of the slider is achieved through mechanical components such as pins or baffles. However, these solutions still have certain limitations in practical applications:

[0004] Insufficient synchronization: The synchronous movement of the slider relies on a complex linkage mechanism, which is prone to asynchrony due to mechanical wear or assembly errors, thus affecting the detection accuracy.

[0005] Complex reset mechanism: Some devices require an additional reset mechanism (such as a spring or cylinder) to reset the detection pressure plate, which increases the complexity and cost of the structure.

[0006] Limited applicability: Existing devices are mostly designed for specific scenarios, making it difficult to balance the needs of high-precision detection and versatility.

[0007] Therefore, there is an urgent need for a thickness detection device that is simple in structure, easy to operate, highly stable, and applicable to various scenarios, in order to meet the needs of modern industry for high-precision detection and efficient production. Utility Model Content

[0008] To address the shortcomings of the aforementioned technologies, this utility model provides a pin locking device.

[0009] To solve the above technical problems, the technical solution adopted by this utility model is: a pin locking device, including a first linear slide rail and a first slider and a second slider that are slidably disposed on the first linear slide rail;

[0010] The first slider is provided with a fixing pin, which moves from top to bottom through the second slider and is restricted from moving out of the second slider by the first baffle at the end of the fixing pin. When the second slider moves downward, the first slider and the second slider move synchronously through the fixing pin.

[0011] A movable pin is slidably mounted on the first slider. The movable pin is parallel to the fixed pin. A detection pressure plate is connected to the movable pin. A detection support plate is mounted on the first slider. The detection pressure plate is located above the detection support plate and is aligned vertically.

[0012] The movable pin is inserted into the first slider from top to bottom and is restricted from moving out of the first slider by the second baffle at the end of the movable pin. When the second slider moves upward, the second slider pushes the movable pin to move synchronously on the first slider, so that the detection pressure plate moves away from the detection tray. When the second slider moves downward, the weight of the movable pin drives the detection pressure plate to move closer to the detection tray.

[0013] Furthermore, a push plate protrudes from the second slider, and a fixing pin is movably inserted into the perforated end plate of the push plate. The diameter of the first baffle is larger than the inner diameter of the perforated end plate.

[0014] Furthermore, a second linear slide is provided on the first slider, and a third slider is provided on the second linear slide. The third slider is connected downward to a moving pin and upward to a detection pressure plate.

[0015] Furthermore, a positioning block is protruding from the first slider, and the end of the fixed pin away from the first baffle is fixedly connected to the positioning block. The movable pin moves through the perforated end plate two on the positioning block, and the diameter of the second baffle is larger than the inner diameter of the perforated end plate two.

[0016] Furthermore, the testing plate includes a vertical plate and a horizontal plate. The vertical plate is movably inserted into the testing tray and laterally bent above the testing tray by the horizontal plate.

[0017] This invention provides a pin locking device with the following significant advantages: Through the ingenious cooperation of the fixed pin and the movable pin, the synchronous movement of the first and second sliders is achieved, ensuring the stability and accuracy of the device during operation and avoiding the jamming or misalignment problems caused by asynchronous sliders in traditional devices. This design not only simplifies the structure but also improves the reliability of the device, making it particularly suitable for scenarios requiring high-precision positioning and detection. The movable pin resets the detection plate using its own weight, eliminating the need for additional reset mechanisms (such as springs or cylinders), significantly reducing manufacturing costs and maintenance difficulty, while also reducing the complexity and failure rate of the device. This gravity-based reset design is not only efficient but also further optimizes the overall structure of the device, making it more compact and lightweight. The cooperation between the detection plate and the detection tray provides a simple and reliable thickness detection mechanism, enabling rapid determination of the thickness of the object being measured through their contact or separation, suitable for various scenarios such as precision parts inspection and food processing. The design of the detection plate and the detection tray can also embed thickness sensors according to actual needs, further improving detection accuracy and meeting the requirements of high-precision measurement. The device features a compact overall structure, simple operation, and easy installation and maintenance, making it adaptable to various industrial environments. Furthermore, the rational layout of components such as the push plate and positioning blocks ensures the stability and range of motion of both the fixed and movable pins, further enhancing the device's durability and service life. The up-and-down movement of the second slider can be achieved manually or mechanically (e.g., by a cylinder or electric push rod), providing flexible operation to suit different application scenarios and user needs. In summary, this invention, through innovative structural design and functional optimization, provides a highly efficient, reliable, and low-cost pin locking device. It not only solves the problems of insufficient synchronization, complex reset mechanisms, and limited applicability in traditional devices but also offers a novel solution for thickness detection and other related applications, possessing broad application prospects and practical value.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] In this embodiment, as Figure 1-4 The illustrated pin locking device includes a first linear slide 1 and a first slider 2 and a second slider 3 slidably disposed on the first linear slide 1. The first linear slide 1 provides a moving track for the sliders, ensuring that the first slider 2 and the second slider 3 can move on the slide 1. The linear design of the slide simplifies the structure, facilitates the precise movement and positioning of the sliders, and reduces the complexity of manufacturing and assembly.

[0025] A fixing pin 4 is provided on the first slider 2. The fixing pin 4 is movably inserted into the second slider 3 from top to bottom, and is restricted from moving out of the second slider 3 by the first baffle 8 at the end of the fixing pin 4. When the second slider 3 moves downward, the first slider 2 and the second slider 3 are dragged by the fixing pin 4 to move synchronously. The fixing pin 4 connects the first slider 2 and the second slider 3, ensuring that they can move synchronously when moving downward. Therefore, the design of the fixing pin 4 ensures that the first slider 2 and the second slider 3 can maintain synchronization when moving downward, while the first baffle 8 prevents the fixing pin 4 from disengaging from the second slider 3, thus enhancing the stability of the structure. When the second slider 3 moves downward, the first slider 2 and the second slider 3 move synchronously by the fixing pin 4. The linkage of the fixing pin 4 ensures that the two sliders maintain synchronization when moving downward, avoiding jamming or misalignment caused by asynchrony. Specifically, a push plate 10 is protruding from the second slider 3, and the fixing pin 4 is movably inserted into the perforated end plate 11 on the push plate 10. The diameter of the first baffle 8 is larger than the inner diameter of the perforated end plate 11. The cooperation between the push plate 10 and the perforated end plate 11 ensures the stability of the fixing pin 4 when they come into contact, while the first baffle 8 prevents the fixing pin 4 from disengaging from the second slider 3.

[0026] A movable pin 5 is slidably mounted on the first slider 2, parallel to the fixed pin 4. A detection pressure plate 6 is connected to the movable pin 5. A detection support plate 7 is mounted on the first slider 2, with the detection pressure plate 6 positioned above and aligned vertically with the detection support plate 7. The contact or separation between the detection pressure plate 6 and the detection support plate 7 provides a simple and reliable detection mechanism for testing the thickness of the product to be tested on the detection support plate 7.

[0027] The movable pin 5 is inserted into the first slider 2 from top to bottom, and its movement is restricted by the second baffle 9 at its end. When the second slider 3 moves upward, it pushes the movable pin 5 to move synchronously on the first slider 2, causing the detection plate 6 to move away from the detection support plate 7. When the second slider 3 moves downward, the weight of the movable pin 5 pulls the detection plate 6 closer to the detection support plate 7. The second baffle 9 ensures the sliding range of the movable pin 5 on the first slider 2, preventing it from detaching from the first slider 2. Specifically, a positioning block 14 protrudes from the first slider 2. The end of the fixed pin 4 away from the first baffle 8 is fixedly connected to the positioning block 14. The movable pin 5 is movably inserted into the perforated end plate 15 on the positioning block 14. The diameter of the second baffle 9 is larger than the inner diameter of the perforated end plate 15. The cooperation between the positioning block 14 and the perforated end plate 15 ensures the installation position and range of motion of the fixed pin 4 and the movable pin 5. Simultaneously, the movement of the second slider 3 drives the movement of the movable pin 5, thereby changing the position of the detection plate 6. When the second slider 3 moves downward, the detection plate 6 is reset by the weight of the movable pin 5. Therefore, no additional reset mechanism is needed; reset is achieved by gravity, simplifying the structure and reducing costs.

[0028] In other embodiments, it should be understood that the upward movement of the second slider 3 can be achieved by manual or mechanical braking, wherein mechanical braking can be achieved by using an additional cylinder or electric push rod.

[0029] In this embodiment, a second linear slide rail 12 is provided on the first slider 2, and a third slider 13 is provided on the second linear slide rail 12. The third slider 13 is connected downward to the movable pin 5 and upward to the detection pressure plate 6. Through the cooperation of the second linear slide rail 12 and the third slider 13, the linkage between the movable pin 5 and the detection pressure plate 6 is realized. The design of the second linear slide rail 12 simplifies the connection structure between the movable pin 5 and the detection pressure plate 6, while the sliding of the third slider 13 ensures the precise movement of the detection pressure plate 6.

[0030] The detection plate 6 includes a vertical plate 16 and a horizontal plate 17. The vertical plate 16 is movably inserted into the detection tray 7 and is laterally bent above the detection tray 7 by the horizontal plate 17.

[0031] In the above embodiments, the working principle of the entire pin locking device based on the up-and-down movement of the second slider is as follows:

[0032] 1. When moving downwards:

[0033] The second slider 3 moves downward, causing the first slider 2 to move downward synchronously via the fixed pin 4. The moving pin 5, under its own weight, moves the detection pressure plate 6 closer to the detection tray 7, thereby detecting the thickness of the object. It should be understood that this patent provides a novel mechanism for moving the detection pressure plate and detection tray. Under this mechanism, the method for detecting the thickness of an object is not limited to one. For example, thickness sensors can be embedded in the pressure plate and detection tray to achieve accurate measurement of the object under test, which is particularly suitable for precision parts. Alternatively, in other processes where accurate measurement is not required, such as in the process of detecting the thickness of processed food, when the second slider 3 moves downward to a predetermined position, it can be determined, either by the position sensor or by checking whether the first slider 2 has moved downward to the predetermined position simultaneously, whether the thickness of the processed food meets the standard. Of course, this mechanical design can also be used independently as a pressing mechanism.

[0034] 2. When moving upwards:

[0035] The second slider 3 moves upward, pushing the movable pin 5 to move upward synchronously on the first slider 2 via the push plate 10. The movable pin 5 drives the detection pressure plate 6 away from the detection tray 7, separating the detection pressure plate 6 from the detection tray 7, making it convenient to place the object to be detected on the detection tray 7. Note that the fixing pin 4 is slidably set on the push plate 10.

[0036] This pin locking device, through the cooperation of the fixed pin 4 and the movable pin 5, realizes the synchronous downward movement of the first slider 2 and the second slider 3 and the upward movement of the detection pressure plate 6 away from the detection support plate 7. It provides a simple and reliable detection mechanism. The whole device is compact, easy to operate, and highly stable, and is suitable for mechanical systems that require high-precision positioning and detection.

[0037] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
