Abstract
Description
Technical Field
[0001] This utility model belongs to the field of O-ring assembly technology, specifically relating to a quick-connect O-ring assembly and testing mechanism. Background Technology
[0002] In the field of mechanical manufacturing, O-rings are common sealing elements, and their assembly quality directly affects the sealing performance and operational reliability of equipment. Currently, the assembly of O-rings inside workpieces mostly relies on manual labor or semi-automatic equipment, resulting in problems such as low assembly efficiency and high labor intensity.
[0003] During manual assembly, operators must manually insert O-rings into the grooves on the inner wall of the workpiece. Visual errors or uneven application of force can easily cause the O-rings to become misaligned, fall off, or even damage the workpiece. While existing automated assembly equipment can perform basic assembly actions, it lacks an effective real-time detection mechanism. This makes it difficult to accurately determine whether the O-rings are fully inserted into the groove, or whether there are any omissions or misalignments. This necessitates adding an extra inspection step, increasing production and time costs. Utility Model Content
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a quick-connect O-ring assembly and testing mechanism, including a frame, a lifting drive mechanism, a plug, and a workpiece fixing fixture. The frame is provided with a vertical slide rail, and a vertical slider is installed on the vertical slide rail. The plug is installed on the vertical slider. The lifting drive mechanism drives the vertical slider to move on the vertical slide rail. The workpiece fixing fixture is located directly above the plug. The frame is provided with an upper sensor, a middle sensor, and a lower sensor for sensing the height of the vertical slider. The upper sensor, the middle sensor, and the lower sensor are arranged sequentially from top to bottom.
[0005] As a preferred embodiment of the above technical solution, the plug is connected to a vertical slider by bolts, and a guide post is provided at the middle of the upper end of the plug. An annular platform is formed between the guide post and the upper end face of the plug, and the guide post is connected to the plug by bolts.
[0006] As a preferred embodiment of the above technical solution, a number of support blocks are evenly spaced on the annular platform.
[0007] As a preferred embodiment of the above technical solution, the lifting drive mechanism is a cylinder, the output shaft of the cylinder is connected to a vertical slider, and a pressure sensor is provided between the output shaft of the cylinder and the vertical slider.
[0008] As a preferred embodiment of the above technical solution, the workpiece fixing fixture is a robotic arm.
[0009] As a preferred embodiment of the above technical solution, the upper sensor, middle sensor and lower sensor are all inductive proximity sensors, and an iron sheet is fixed on the vertical slider.
[0010] As a preferred embodiment of the above technical solution, the number of the testing mechanisms is two sets, and the two sets of testing mechanisms share a single frame.
[0011] The beneficial effects of this utility model are as follows: The quick-connect O-ring assembly and inspection mechanism of this utility model, through the cooperation of lifting drive and multiple sensors, realizes the integration of O-ring assembly and inspection, thereby improving the level of automation. Upper, middle, and lower sensors accurately monitor the slider position, and combined with a pressure sensor, can determine whether the O-ring is in the groove, misaligned, or over-assembled. The dual-inspection mechanism design improves batch production efficiency. Attached Figure Description

[0013] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0016] like Figure 1-2As shown, the quick-connect O-ring assembly and inspection mechanism (in this embodiment, the workpiece is a quick-connect plug 15) includes a frame 1, a lifting drive mechanism, a plug 2, and a workpiece fixing fixture. The frame 1 is equipped with a vertical slide rail 3, and a vertical slider 4 is mounted on the vertical slide rail 3. The plug 2 is mounted on the vertical slider 4. The lifting drive mechanism drives the vertical slider 4 to move on the vertical slide rail 3. The workpiece fixing fixture is located directly above the plug 2. The frame 1 is equipped with an upper sensor 5, a middle sensor 6, and a lower sensor 7 for sensing the height of the vertical slider 4, arranged sequentially from top to bottom. The workpiece fixing fixture fixes the workpiece directly above the plug 2. During inspection, the vertical slider 4 rises and moves on the vertical slide rail 3, causing the plug 2 to rise and insert into the workpiece. The plug 2 contacts the O-ring 13 inside the workpiece or the workpiece itself, or stops rising after reaching a set maximum height. When the upper sensor 5 senses the position of the vertical slider 4, it indicates that the O-ring 13 is missing from the workpiece, indicating a missing component. When the middle sensor 6 detects the position of the vertical slider 4, it indicates that there is an O-ring 13 inside the workpiece, and the O-ring 13 is accurately assembled. When the lower sensor 7 detects the position of the vertical slider 4, it indicates that there are multiple O-rings 13 inside the workpiece, or that the O-rings 13 are not assembled correctly. The upper sensor 5, the middle sensor 6, and the lower sensor 7 are detachably mounted on... Furthermore, the plug 2 is bolted to the vertical slider 4, and a guide post 8 is provided at the upper center of the plug 2. An annular platform 9 is formed between the guide post 8 and the upper surface of the plug 2. The guide post 8 is bolted to the plug 2. When the plug 2 is inserted into the workpiece and contacts the O-ring 13, the guide post 8 inserts into the O-ring, and the O-ring blocks the annular platform 9. The plug 2 and the guide post 8 are detachable for easy replacement.
[0017] Furthermore, a plurality of support blocks 10 are evenly spaced on the annular stage 9. The support blocks 10 reduce the contact area between the O-ring and the annular stage 9, so that when the plug 2 is removed from the workpiece after the test is completed, it will not affect the O-ring 13.
[0018] Furthermore, the lifting drive mechanism is a cylinder 11, and the output shaft of the cylinder 11 is connected to the vertical slider 4. A pressure sensor 12 is provided between the output shaft of the cylinder 11 and the vertical slider 4. The pressure sensor 12 senses the pressure change on the vertical slider 4. When the plug 2 presses against the O-ring 13 inside the workpiece or the workpiece, the pressure signal sensed by the pressure sensor 12 increases, the cylinder 11 stops its upward movement, the vertical slider 4 remains stationary, and the upper sensor 5, the middle sensor 6, or the lower sensor 7 generates a position signal for the vertical slider 4.
[0019] Furthermore, the workpiece clamping fixture is a robotic arm. The robotic arm grasps the workpiece, transfers it, and positions it above the plug 2. The robotic arm can be a pneumatic gripper controlled by a robot, as is available in the prior art.
[0020] Furthermore, the upper sensor 5, middle sensor 6, and lower sensor 7 are all inductive proximity sensors, and an iron plate 14 is fixed on the vertical slider 4. When the iron plate 14 moves up and down with the vertical slider 4, it passes the position of the upper sensor 5, middle sensor 6, or lower sensor 7 and is sensed by the corresponding inductive proximity sensor, forming an induction signal, thereby obtaining the assembly status of the O-ring 13 inside the workpiece.
[0021] Furthermore, the number of the inspection mechanisms is two sets, and the two sets of inspection mechanisms share a single frame 1. The two sets of inspection mechanisms form a dual-station simultaneous inspection, improving the assembly and inspection efficiency of the O-rings 13 inside the workpiece.
[0022] It is worth mentioning that the inductive proximity sensor, pressure sensor 12, cylinder 11, and robotic arm involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.
[0023] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
