Description

Technical Field

[0001] This utility model belongs to the field of inspection and fixture technology, and specifically relates to a self-locking sheet metal rivet inspection fixture. Background Technology

[0002] Sheet metal rivet inspection fixtures are tools used to ensure that the quality of rivets used in sheet metal assemblies meets design standards and specifications. In the manufacturing process, especially in industries such as aerospace, automotive, and electronics, the use of high-quality rivets is crucial to ensuring the structural integrity and safety of the final product. Therefore, inspecting these rivets for correct installation and the presence of defects becomes particularly important.

[0003] As manufacturing demands increasingly higher product quality, traditional manual inspection methods are no longer sufficient to meet the speed and precision requirements of modern production. Existing inspection tools often lack effective error prevention mechanisms (i.e., mechanisms to prevent errors) for missing rivets. This means that in actual production, there may be instances where rivets that should be installed are actually omitted, and conventional inspection tools may not be able to effectively identify such errors.

[0004] Furthermore, during the production process, the identification of unqualified samples is easily affected by external factors, resulting in the samples not being locked. This situation can easily lead to unqualified samples being mixed with qualified samples, and the quality of the final product cannot be guaranteed. Unqualified rivets may cause insufficient connection strength, which in turn affects the structural integrity of the entire component or even the equipment.

[0005] Therefore, the above situation urgently needs to be addressed. Utility Model Content

[0006] Purpose of the utility model: To overcome the above shortcomings, the purpose of this utility model is to provide a self-locking sheet metal rivet inspection fixture, which overcomes the inefficiency of traditional inspection tools and effectively prevents unqualified products from being incorrectly classified into the qualified product area. It not only improves the speed and accuracy of inspection but also greatly enhances the quality control level during the inspection process.

[0007] Technical Solution: A self-locking sheet metal rivet inspection fixture includes a housing, an inspection area, and a self-locking component. The inspection area is embedded in the housing, and its inspection surface is flush with the housing surface. The self-locking component is located on the side of the housing. A product is placed on the inspection area, and a sensor group is correspondingly arranged at its bottom. A counter, signal indicator light, lightning buzzer, and unlocking area are arranged on the housing. This application, by setting a sensor group at the bottom of the inspection area, can accurately detect the presence and position of sheet metal rivets, thereby ensuring that each rivet is accurately inspected. Furthermore, the self-locking component increases safety. When a defective product is detected, the self-locking component can automatically lock, preventing the component from entering the next process or leaving the production line, ensuring the consistency and reliability of product quality.

[0008] Furthermore, the self-locking assembly includes a cylinder and an output rod, with the output rod connected to the cylinder. The cylinder is positioned on the side facing the product, and the output rod abuts against and locks the product in the locked state. The cylinder-driven output rod of this application typically operates very rapidly, reacting immediately upon detecting a defective product and pushing the output rod out to lock the product. This rapid response capability helps to immediately prevent defective products from entering subsequent production stages, reducing the risk of error accumulation.

[0009] Furthermore, the product has through holes on both sides, and the detection area is provided with positioning pins and positioning protrusions corresponding to the through holes on the product for positioning. The presence of positioning pins and positioning protrusions in this application improves the accuracy and repeatability of positioning, and makes the product more stable during the detection process, reducing the risk of positional displacement caused by vibration or external force.

[0010] Furthermore, the sensor group includes a first metal sensor, a product sensor, and a second metal sensor. The first and second metal sensors are respectively aligned with the positions of a first rivet and a second rivet disposed on the product, and the product sensor is disposed between the first and second metal sensors. This application, by aligning the first and second metal sensors with the positions of the first and second rivets on the product, can accurately detect the state of these critical components. This method ensures that each rivet is accurately inspected, improving the overall accuracy of the inspection.

[0011] Furthermore, the unlocking area is equipped with a keyhole and a key for unlocking the self-locking component. This application adds an extra layer of security by using a dedicated keyhole and key to unlock the device. Only authorized personnel can use a specific key to perform the unlocking operation, which helps prevent unauthorized personnel from arbitrarily unlocking the device and avoids potential operational errors or quality issues.

[0012] Furthermore, multiple sets of recesses are provided on the detection area. The width of each recess is greater than that of the product, and they are located at the lower end of the product. Because the recesses are wider, operators can more easily handle the product, improving accuracy.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. This application relates to a self-locking sheet metal rivet inspection fixture. By setting a sensor group at the bottom of the inspection area, the presence and position of sheet metal rivets can be accurately detected, thereby ensuring that each rivet is inspected accurately. Furthermore, the self-locking component increases safety. When a defective product is detected, the self-locking component can automatically lock, preventing the component from entering the next process or leaving the production line, thus ensuring the consistency and reliability of product quality.

[0014] 2. This application relates to a self-locking sheet metal rivet inspection fixture. The cylinder-driven output rod typically moves very quickly, reacting immediately upon detecting a defective product by pushing the output rod out to lock the product. This rapid response capability helps to immediately prevent defective products from entering subsequent production stages, reducing the risk of error accumulation.

[0015] 3. This application relates to a self-locking sheet metal rivet inspection tool, which adds an extra layer of security by using a special keyhole and key to unlock. Only authorized personnel can use a specific key to unlock the rivet, which helps prevent unauthorized personnel from arbitrarily unlocking it and avoids potential operational errors or quality hazards.

Figure 1 As shown, it includes an outer shell 1, a detection area 2, and a self-locking component 3; the detection area 2 is embedded in the outer shell 1, and the detection surface 200 of the detection area 2 is flush with the shell surface 100 of the outer shell 1; the self-locking component 3 is disposed on the side of the outer shell 1; the product 4 is placed on the detection area 2, and a sensor group is correspondingly disposed at the bottom; a counter 101, a signal indicator light 102, a lightning buzzer 103, and an unlocking area 104 are disposed on the upper part of the outer shell 1.

[0020] Furthermore, the self-locking assembly 3 includes a cylinder 301 and an output rod 302, the output rod 302 being connected to the cylinder 301; the cylinder 301 is positioned on one side facing the product 4, and the output rod 302 abuts against and locks the product 4 in the locked state.

[0021] Furthermore, the unlocking area 104 is provided with a keyhole and a key for releasing the locking state of the self-locking component 3.

[0022] For further details, please refer to... Figure 2 As shown, the sensor group includes a first metal sensor 201, a product sensor 202, and a second metal sensor 203. The first metal sensor 201 and the second metal sensor 203 are respectively aligned with the positions of the first rivet 401 and the second rivet 402 disposed on the product 4. The product sensor 202 is disposed between the first metal sensor 201 and the second metal sensor 203.

[0023] For further details, please refer to... Figure 3 As shown, the product 4 has through holes on both sides, and the detection area 2 is provided with positioning pins 204 and positioning protrusions 205 at the corresponding through holes on the product 4 for positioning.

[0024] Furthermore, multiple sets of recesses 206 are provided on the detection area 2. The width of the recesses 206 is greater than that of the product 4, and they are located at the lower end of the product 4.

[0025] Furthermore, the working steps of the self-locking sheet metal rivet inspection fixture include: Step S1, Product Placement and Positioning: The operator first places the product 4 to be inspected on the inspection area 2. The through holes on both sides of the product 4 are aligned with the positioning pins 204 and positioning protrusions 205 on the inspection area 2 to ensure that the product position is accurately fixed.

[0026] Step S2, Sensor Detection: After positioning is completed, the first metal sensor 201, the product sensor 202, and the second metal sensor 203 located at the bottom of the detection area 2 begin to work.

[0027] Furthermore, the first metal sensor 201 is aligned with the first rivet 401 on the product 4 to detect its presence and whether its status is correct.

[0028] Furthermore, the second metal sensor 203 is also aligned with the position of the second rivet 402 for detection.

[0029] Furthermore, the product sensor 202 is positioned between the first metal sensor 201 and the second metal sensor 203 to detect the overall state of the product 4, such as whether its position is correct.

[0030] Step S3, Result Feedback: If all sensor groups detect the expected result, i.e. the rivet is present and in the correct position, and the overall condition of the product is good, the signal indicator 102 will light up green, indicating that the test has passed; at the same time, the counter 101 records the number of qualified products.

[0031] If any sensor detects a defect, such as a missing rivet, the lightning buzzer 103 will sound an alarm, and the indicator light 102 will turn red.

[0032] Step S4, Automatic Locking: Upon detecting a defective product 4, the self-locking component 3 is activated. The cylinder 301 pushes the output rod 302 forward until the output rod 302 abuts against and locks the product 4, preventing it from continuing to the next production stage.

[0033] Step S5, Unlocking Operation: When it is necessary to unlock the self-locking component 3, authorized personnel use a specially equipped key to insert into the keyhole on the unlocking area 104, follow specific operating procedures to unlock, and remove the unqualified product 4 for further inspection or processing.

[0034] Step S6: Repeat the above steps.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
