Description
Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a mechanical seal O-ring compression measurement fixture. Background Technology
[0002] The mechanical seal O-ring compression measurement fixture is a device used to accurately measure the compression amount. It consists of a base, positioning component, and pressure head, which can firmly clamp the O-ring, ensure a consistent measurement benchmark, reduce human error, and obtain reliable data based on stable measurement performance. This provides a basis for optimizing seal design parameters, improves the overall performance of the mechanical seal, and ensures the sealing performance of the equipment.
[0003] Traditional mechanical seal O-ring compression measurement fixtures mostly adjust the compression amount by manually rotating the screw to adjust the pressure head, and then read the value with the help of vernier calipers and dial indicators. The operation depends on the operator to manually control the compression process and judge the reading. This method has the problems that the measurement accuracy is greatly affected by the operator's experience, the uniformity of compression adjustment is poor, and the results of multiple measurements of the same O-ring are significantly different.
[0004] Existing mechanical seal O-ring compression measurement fixtures typically use a motor-driven pressure head to achieve automated compression, and are equipped with displacement and force sensors to collect data in real time. The compression changes are recorded through a control structure. However, the problem of manual cleaning of the inner ring plate still exists. To address this issue, a mechanical seal O-ring compression measurement fixture is proposed. Utility Model Content

The inner wall of the collection groove 6055 is connected to a collection pipe 6052, whose main function is to transport the dirt. The inner wall of the collection pipe 6052 is threadedly connected to two threaded pipes 6053, whose main function is to enable the collection pipe 6052 to be assembled and disassembled in sections. The outer wall of the collection pipe 6052 is connected to a collection box 6054, whose main function is to centrally store all the cleaned impurities for easy subsequent unified cleaning.
[0036] Specifically, the cleaning mechanism 6 includes a cleaning ring 601, which focuses its cleaning on a specific area to ensure targeted cleaning. Simultaneously, multiple nozzles 602 on the inner wall of the cleaning ring 601, driven by gas, clean the area. Gas is delivered to the cleaning ring 601 via an air supply pipe 606 on its outer wall.

[0038] Specifically, the buffer mechanism 7 includes a connecting plate 702, which transmits the driving force of the telescopic rod 5 to the buffer assembly below. The buffer spring 703 at the bottom of the connecting plate 702 relieves pressure through the spring's buffering force.

The connecting plate 707 at the bottom of the telescopic cover 705 provides an installation base for the lower limiting block 704 and the telescopic cover 705, ensuring the stability of the lower structure. Meanwhile, the anti-collision pads 706 on the outer walls of the two limiting blocks 704 prevent hard contact from causing deformation of the limiting blocks 704 and extend the service life of the components. The limiting pad 701 at the bottom of the connecting plate 707 prevents the O-ring from slipping and shifting during compression, ensuring accurate compression positioning.
[0039] Reference Figure 1 , Figure 2 and Figure 3A stabilizing plate 14 is fixedly connected to the bottom of the chassis 1. Its main function is to prevent the chassis 1 from tilting due to its own weight and operating vibration. A stabilizing table 2 is fixedly connected to the bottom of the stabilizing plate 14. Its main function is to provide a fixed support. A hinge 10 is fixedly connected to the inner wall of the chassis 1. Its main function is to provide an operating channel for the maintenance of the internal components of the chassis 1. A cover plate 11 is rotatably connected to the outer wall of the hinge 10. A waterproof gasket 12 is fixedly connected to the outer wall of the cover plate 11. Its main function is to work with the cover plate 11 to prevent external dust from entering the interior. A fixed... Plate 2 9, its main function is to provide stable support for the components. The top of the fixed plate 2 9 is fixedly connected to the fixed rod 15.

The inner wall of the threaded groove 8 is threadedly connected to the threaded fixed plate 16, which is mainly used to ensure the O-ring is in a stable position during testing. The outer wall of the micro air pump 604 is fixedly connected to the inner wall of the chassis 1. The outer wall of the cover plate 2 11 is fixedly connected to the observation plate 13, which is mainly used to facilitate the operator to observe the internal working conditions and process of the chassis 1.
[0040] Specifically, the stabilizing plate 14 at the bottom of the chassis 1 prevents the chassis 1 from tilting due to its own weight and working vibration. At the same time, the stabilizing table 2 at the bottom of the stabilizing plate 14 provides a fixed support. The hinge 10 on the inner wall of the chassis 1 provides an operating channel for the maintenance of the internal components of the chassis 1. The waterproof pad 12, together with the cover plate 11, prevents external dust from entering the interior. The fixing plate 9 on the inner wall of the chassis 1 provides stable support for the components. At the same time, the threaded groove 8 on the outer wall of the fixing rod 15, together with the fixing rod 15, enables the installation of the threaded fixing plate 16. The threaded fixing plate 16 on the inner wall of the threaded groove 8 ensures that the O-ring is in a stable position during testing. Meanwhile, the observation plate 13 on the outer wall of the cover plate 11 allows the operator to easily observe the internal working conditions and process of the chassis 1, as well as the internal cleaning effect.
[0041] Working principle: First, the cleaning mechanism 6 continuously supplies air through the micro air pump 604 and the air supply pipe 606 to provide stable power to the nozzles 602, ensuring sufficient cleaning force. At the same time, through the multiple nozzles 602 distributed on the cleaning ring 601, the airflow is blown out by the nozzles 602 to sweep the inside of the inner ring plate 17, removing attached impurities and dust. When disassembly is required, the air supply pipe 606 and the collection pipe 6052 are disassembled through the threaded pipe 1 603 and the threaded pipe 2 6053. The cover plate 1 6051, in conjunction with the collection trough 6055, collects the swept-down dirt and then transports it to the collection box 6054 through the collection pipe 6052. This achieves simultaneous cleaning and collection, keeping the cleaned area clean, avoiding secondary pollution, and improving environmental cleanliness.
[0042] Furthermore, when the connecting plate 707 is subjected to pressure, the buffer spring 703 connected to the connecting plate 707 can flexibly extend and retract to quickly absorb the impact force and reduce the vibration amplitude. At the same time, the telescopic cover 705 moves in coordination to play an auxiliary buffering role and protect the internal structure. Through the cooperation of the limiting block 704 and the anti-collision pad 706, damage caused by the impact force can be effectively avoided, forming double protection. Meanwhile, the bottom limiting pad 701 further plays a buffering role, continuously dissipating external forces and improving the service life of the equipment.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
