Description

Technical Field

[0001] The utility model relates to the technical field of chain production, in particular to a chain pin shaft fitting force detection device. Background Art

[0002] In the chain manufacturing industry, chain quality is directly linked to the safety and reliability of its subsequent applications. Chains are composed of multiple links connected by pins, and the quality of the fit between the pins and the links directly determines the overall strength and durability of the chain. However, in actual production, due to factors such as material differences, processing fluctuations, or equipment precision limitations, it is often difficult to ensure a completely consistent fit between the pins and the links. This can lead to safety hazards such as loosening and breakage during chain use.

[0003] Traditional chain pin force testing methods rely on manual experience or simple mechanical measurements. These methods suffer from low accuracy, low efficiency, and poor adaptability. Manual testing is susceptible to subjective factors, making it difficult to ensure accurate and consistent test results. Simple mechanical measurements can only test a single chain specification and are unable to adapt to the needs of chains of varying sizes. Utility Model Content

[0007] Preferably, a plurality of the limiting plates are in contact with the placement plate, and the driving rod is fixedly connected to the eccentric portion of the limiting plates.

[0008] Preferably, a door is installed on the front wall of the box.

Compared with traditional manual detection or rough mechanical detection methods, the accuracy and reliability of detection are greatly improved.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0016] like Figure 1As shown, the embodiment of the present invention provides a chain pin fitting force detection device, including a box body 1, a pressure sensor 2, a first motor 4 and a second motor 8, the two pressure sensors 2 are symmetrically installed on the inner top wall of the box body 1, and a pressure plate 3 is installed at the bottom of the pressure sensor 2, the first motor 4 is fixedly connected to the top of the box body 1, and the driving end of the first motor 4 is fixedly connected to a screw rod 5, which is located inside the box body 1 and on one side of the two pressure plates 3. The outer surface of the screw rod 5 is threadedly connected to a placement plate 6, and the placement plate 6 is slidably engaged with the inside of the box body 1, and the placement plate 6 is located below the pressure plate 3. Two slots 7 are symmetrically penetrated at the top of the placement plate 6, and the two pressure plates 3 are respectively located directly above the two slots 7. The front wall of the slot 7 and the front surface of the placement plate 6 are in the same plane, and multiple second motors 8 are fixedly connected to the bottom of the placement plate 6, and the driving end of the second motor 8 is fixedly connected to a drive rod 9, which penetrates the placement plate 6, and the top of the drive rod 9 is fixedly connected to a limit plate 10, and the two slots 7 are both located between the multiple limit plates 10.

[0017] The bottom end of screw rod 5 is pivotally connected to the inner bottom wall of housing 1. This design ensures the stability of screw rod 5 when driving the placement plate 6 up and down. This pivoting connection not only provides stable support for screw rod 5 but also allows it to rotate smoothly under the drive of first motor 4, thereby precisely controlling the height of placement plate 6. This stable lifting mechanism is crucial for ensuring accurate contact between the pin, pressure sensor 2, and pressure plate 3 during the testing process.

[0018] Multiple limiting disks 10 are in contact with the placement plate 6, and the drive rod 9 is fixedly connected to the eccentric portion of the limiting disks 10. This design enables the limiting disks 10 to more effectively clamp the outer link plates. When the second motor 8 drives the drive rod 9 to rotate, the limiting disks 10 rotate eccentrically around the drive rod 9 due to the fixed connection between the drive rod 9 and the eccentric portion of the limiting disks 10. This eccentric rotation allows the limiting disks 10 to gradually press against and clamp the outer link plates placed on the placement plate 6, thereby ensuring that the outer link plates remain stationary during the inspection process. In addition, the direct contact between the limiting disks 10 and the placement plate 6 also increases the stability of the clamping, preventing the outer link plates from moving or shaking during the inspection process.

[0019] A door is installed on the front wall of the box 1. This design facilitates the operator's insertion and removal of the outer link plate into and out of the testing device. By opening the door, the operator can easily place the outer link plate with the embedded pin on the placement plate 6 and remove it after testing. This design not only improves operational convenience but also makes the entire testing process more efficient.

[0020] Working principle: When using the chain pin fitting force detection device, the operator places the outer chain plate with the pin from the box door on the box body 1 onto the placement plate 6, so that the pin enters the slot 7 on the placement plate 6, and the outer chain plate is located between multiple limit plates 10. Then, the second motor 8 drives the driving rod 9 to drive the limit plates 10 to rotate eccentrically, so that the multiple limit plates 10 are pressed against the outer chain plate, so that the outer chain plate on the placement plate 6 is clamped and fixed. Since the position of the limit plates 10 can be changed, multiple limit plates 10 can clamp and fix outer chain plates of different specifications and sizes. , and then the first motor 4 can drive the screw rod 5 to drive the placement plate 6 to move linearly upward along the inner wall of the box body 1, so that the outer chain plate clamped and fixed on the placement plate 6 moves upward, so that the pin shaft engaged in the pin shaft hole of the outer chain plate contacts the pressure plate 3 on the pressure sensor 2. The first motor 4 gives the outer chain plate pin shaft an upward force, so that the pressure sensor 2 can be subjected to pressure, so that when the pin shaft disengages from the pin shaft hole of the outer chain plate, the pin shaft will directly fall to the inner bottom wall of the box body 1, and then the pressure sensor 2 is no longer subjected to force, so the final reading is the size of the chain pin shaft engagement force.

[0021] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
