Description

Technical Field

[0001] This utility model belongs to the field of pin processing technology, specifically relating to a pin bending inspection tool. Background Technology

[0002] As a commonly used component in mechanical connections and locking systems, the dimensional accuracy and morphological compliance of the bent parts of pins directly affect assembly stability and operational safety. Therefore, bending inspection is a core quality control step in the pin manufacturing process.

[0003] Existing inspection tools mostly use manual knobs or bolts to fix the pins. During operation, the clamping force needs to be adjusted repeatedly, which is not only time-consuming, but also prone to pin displacement due to uneven clamping force, thus affecting the accuracy of subsequent test data. Some simple inspection tools even lack a dedicated clamping structure and rely entirely on manual hand positioning, further increasing the risk of inspection errors. Traditional inspection methods mostly rely on manual measuring tools such as calipers and gauges, requiring operators to measure parameters such as bending angle, arc, and length one by one. This is not only inefficient, but also prone to misjudgment due to human reading errors and measurement point deviations. Especially for curved bends, manual measuring tools cannot fully fit the curved surface and cannot accurately reflect whether the actual bending shape meets the design standards. Improvements are needed. Therefore, it is of great importance to design a pin bending inspection tool to solve the above defects. Utility Model Content

[0004] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a pin bending inspection tool. The base body solves the problem that in the existing technology, inspection tools mostly use manual knobs, bolts, etc. to fix the pins. During operation, the clamping force needs to be adjusted repeatedly, which is not only time-consuming, but also prone to pin displacement due to uneven clamping force, thus affecting the accuracy of subsequent test data.

[0005] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a pin bending inspection tool, which includes a base body; the top of the base body is provided with a receiving groove, the front end of the receiving groove is provided with two sets of clamping components, and the rear end of the receiving groove is slidably connected with multiple sets of detection rods. The clamping assembly is used to clamp and fix the pin. The clamping assembly includes a connecting frame fixedly connected to the front end of the receiving groove. Clamping rods are slidably connected to both sides inside the connecting frame. A support rod is provided between the two sets of clamping rods and inside the connecting frame. A movable plate is fixedly connected to the bottom of the support rod.

[0006] When using the base body of this technical solution, the pin is placed on the support rod. The weight of the pin itself causes the support rod to move downward. As the support rod moves downward, the groove moves downward, and the multiple protrusions move downward, causing the clamping rod to move downward. When the clamping rod moves downward, the arc-shaped structure of the guide groove causes the two sets of clamping rods to move closer to each other and cooperate with the support rod, thus clamping and fixing the pin. When the pin is fixed inside the receiving groove by the clamping assembly, the bent part of the pin contacts the multiple sets of detection rods. The second compression spring drives the connecting ring to move, causing the detection rods to move and fit against the bent part of the pin. Based on the multiple sets of detection marks exposed by the detection rods, the bent part of the pin can be detected. When detecting the pin, the rotating rod drives the rotating rod to rotate through the guide rod, so that the detection block can move in an arc around the rotating rod as the center and contact the pin, thus allowing the hardness of the pin to be detected.

[0007] Preferably, a protrusion is fixedly connected to the bottom of the clamping rod, and grooves are provided on both sides of the bottom of the clamping rod. The internal structure size of the grooves is designed to correspond to the external structure size of the protrusion.

[0008] Furthermore, the connecting frame has sliding grooves at both ends of the two sets of clamping rods. The clamping rods extend into the sliding grooves and are fixedly connected to sliding blocks, which are slidably connected to the sliding grooves.

[0009] Furthermore, multiple guide grooves are provided inside the connecting frame and above multiple sliding grooves. The clamping rod extends into the inside of the guide groove and is fixedly connected to a guide block. The guide block is slidably connected to the guide groove, and the guide groove has an arc-shaped structure design.

[0010] Furthermore, the movable plate is slidably connected to the connecting frame, and a first compression spring is fixedly connected to both sides of the bottom of the movable plate, and the first compression spring is fixedly connected to the connecting frame.

[0011] Furthermore, multiple sets of detection marks are made on the outer side of the detection rod, and a connecting ring is fixedly connected to the inside of the base body extending from the detection rod. A second compression spring is fixedly connected to the end of the connecting ring away from the detection rod.

[0012] Furthermore, a connecting seat is fixedly connected to the top of the base body, and a rotating rod is rotatably connected to the top of the connecting seat. The rotating rod extends to the top of the receiving groove and is fixedly connected to a detection block.

[0013] Furthermore, a guide rod is rotatably connected inside the rotating rod, and a pull rod is rotatably connected to the end of the guide rod away from the rotating rod. The pull rod is rotatably connected to the connecting seat.

[0014] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: The base of this utility model, through the design of clamping components and detection rods, allows the pin to move downwards when placed on the support rod due to its own weight. The engagement of the protrusion and groove causes the clamping rod to move downwards. During this downward movement, the arc-shaped guide groove guides the two sets of clamping rods closer together, automatically clamping the pin with the support rod to prevent displacement during testing. After testing, lifting the pin allows the first compression spring to reset the moving plate and support rod, automatically separating the clamping rods for quick and easy removal. The second compression spring automatically engages the detection rod at the bend of the pin, ensuring complete contact between the detection rod and the bend surface, preventing misjudgments due to insufficient contact. Multiple detection marks on the outer side of the detection rod visually reflect the compliance of the pin's bend. The number of exposed detection marks allows for quick determination of whether the bend size meets the standard, eliminating the need for additional measuring tools. Attached Figure Description

[0016] This specific embodiment is a pin bending inspection tool, the structural diagram of which is shown below. Figure 1-7 As shown, the bending inspection tool includes a base body 1; the top of the base body 1 is provided with a receiving groove 2, the front end of the receiving groove 2 is provided with two sets of clamping components 3, and the rear end of the receiving groove 2 is slidably connected with multiple sets of detection rods 4. The clamping assembly 3 is used to clamp and fix the pin. The clamping assembly 3 includes a connecting frame 5 fixedly connected to the front end of the receiving groove 2. Clamping rods 6 are slidably connected to both sides inside the connecting frame 5. A support rod 7 is provided between the two sets of clamping rods 6 and inside the connecting frame 5. A movable plate 8 is fixedly connected to the bottom of the support rod 7.

[0017] In this embodiment, a protrusion 9 is fixedly connected to the bottom of the clamping rod 6, and grooves 10 are provided on both sides of the bottom of the clamping rod 6. The internal structure size of the groove 10 is designed to correspond to the external structure size of the protrusion 9. When the protrusion 9 is connected to the groove 10, the weight of the pin on the support rod 7 causes the support rod 7 to move downward. When the support rod 7 moves downward, the groove 10 moves downward, causing the protrusion 9 to move, thereby causing the clamping rod 6 to move downward. Secondly, in this embodiment, a sliding groove 11 is provided inside the connecting frame 5 and at both ends of the two sets of clamping rods 6. A sliding block 12 is fixedly connected to the inside of the sliding groove 11. The sliding block 12 is slidably connected to the sliding groove 11. When the clamping rod 6 is displaced, the sliding connection between the sliding block 12 and the sliding groove 11 can guide the clamping rod 6, thereby enabling the clamping rod 6 to be displaced stably. Furthermore, in this embodiment, multiple sets of guide grooves 13 are provided inside the connecting frame 5 and above the multiple sets of sliding grooves 11. The clamping rod 6 extends into the interior of the guide groove 13 and is fixedly connected to the guide block 14. The guide block 14 is slidably connected to the guide groove 13. The guide groove 13 has an arc-shaped structure design. When the clamping rod 6 moves downward, the arc-shaped structure of the guide groove 13 makes the two sets of clamping rods 6 move closer to each other to cooperate with the support rod 7, so that the pin can be clamped and fixed. Furthermore, in this embodiment, the movable plate 8 is slidably connected to the connecting frame 5. The two sides of the bottom of the movable plate 8 are fixedly connected to the first compression spring 15. The first compression spring 15 is fixedly connected to the connecting frame 5. When the pin detection is completed, the pin is lifted, the contact between the support rod 7 and the pin is broken, and the movable plate 8 is moved upward by the first compression spring 15, which causes the support rod 7 to move upward, which causes the groove 10 to move upward, which causes the protrusion 9 to move upward. The guide groove 13 makes the two sets of clamping rods 6 move away from each other, so that the pin can be easily removed. Furthermore, in this embodiment, multiple sets of detection marks 16 are provided on the outer side of the detection rod 4. The detection rod 4 extends into the interior of the base body 1 and is fixedly connected to a connecting ring 17. A second compression spring 18 is fixedly connected to the end of the connecting ring 17 away from the detection rod 4. When the pin is fixed inside the receiving groove 2 by the clamping assembly 3, the bent part of the pin contacts the multiple sets of detection rods 4. The second compression spring 18 drives the connecting ring 17 to move, causing the detection rod 4 to move and fit the detection rod 4 against the bent part of the pin. Based on the multiple sets of detection marks 16 exposed by the detection rod 4, the bent part of the pin can be detected. Furthermore, in this embodiment, a connecting seat 19 is fixedly connected to the top of the base body 1, and a rotating rod 20 is rotatably connected to the top of the connecting seat 19. The rotating rod 20 extends to the top of the receiving groove 2 and is fixedly connected to a detection block 21. A guide rod 22 is rotatably connected inside the rotating rod 20, and a pull rod 23 is rotatably connected to the end of the guide rod 22 away from the rotating rod 20. The pull rod 23 is rotatably connected to the connecting seat 19. When the pin is tested, the rotating pull rod 23 drives the rotating rod 20 to rotate through the guide rod 22, so that the detection block 21 can make an arc displacement with the rotating rod 20 as the center and contact the pin, so that the hardness of the pin can be tested. When using the device of this technical solution, the pin is placed on the support rod 7. The weight of the pin itself causes the support rod 7 to move downward. When the support rod 7 moves downward, the groove 10 moves downward, and the multi-point protrusion 9 moves downward, thereby causing the clamping rod 6 to move downward. When the clamping rod 6 moves downward, the arc-shaped structure of the guide groove 13 causes the two sets of clamping rods 6 to come closer to each other and cooperate with the support rod 7, so that the pin can be clamped and fixed. When the pin is fixed inside the receiving groove 2 by the clamping assembly 3, the bent part of the pin contacts the multi-set detection rods 4, and the second compression spring... Spring 18 drives connecting ring 17 to move, causing detection rod 4 to move and fit against the bend of pin. Multiple sets of detection marks 16 are exposed by detection rod 4, allowing detection of the bend of pin. When detecting pin, rotating pull rod 23 drives rotating rod 20 to rotate through guide rod 22, allowing detection block 21 to move in an arc around rotating rod 20 and contact pin, allowing detection of pin hardness. Compared with existing bending gauges, this utility model improves the overall practicality of bending gauges through design.
