Description

Joint positioning structure for conducting chemicals

This creation is related to a joint positioning structure, especially for positioning vacuum-connected radial sealing joints used in the semiconductor optoelectronics industry.

Press, Vacuum Coupling Radius Seal (VCR) is commonly used in the semiconductor optoelectronics industry to conduct gas or liquid connectors for chemicals. Please refer to Figure 1 for details. The connectors (1) mainly include A first connecting pipe piece (11), a second connecting pipe piece (12), a gasket (13), a male nut (14) and a female nut (15). Wherein, the two ends of the first connecting pipe piece (11) and the second connecting pipe piece (12) respectively form piping ends (111), (121) and sealing ends (112), (with flanges (113) and (123)). 122), and the washer (13) includes a movable washer (131), and is formed on the male nut (14) and the female nut (15) for the first connecting pipe (11) and the second connecting pipe (12) to pass through Let the perforations (141), (151).

When assembling, please refer to Figure 1 and cooperate with Figure 2. It is to insert the first connecting pipe piece (11) and the second connecting pipe piece (12) on the male nut (14) and the female nut ( 15) perforate (141), (151), and set the flange (113) of the first connecting pipe (11) and the flange (123) of the second connecting pipe (12) opposite to each other, and put the gasket (13) Fit the flange (113) of the first connecting pipe (11), and then manually screw the male nut (14) to the female nut (15), so that the movable washer (131) abuts against the first connecting pipe Between the flange (113) of (11) and the flange (123) of the second connecting pipe (12), when the male nut (14) cannot be manually screwed into the female nut (15), use the male nut ( 14) Draw a reference line (L) with one of the corresponding end faces of the female nut (15) as the reference plane, then fix the male nut (14) with a wrench, and turn the female nut (15) with another wrench to rotate About 1/8~1/6 turns, make the reference line (L) of the male nut (14) and the female nut (15) separated by 45°~60°, and then by the flange of the first connecting pipe (11) (113) The flange (123) of the second connecting pipe (12) is pressed against the movable gasket (131) to realize the sealing state of the joint (1) pipeline (as shown in Figure 3).

However, the force applied to the joint (1) by different operators or even the same operator each time using the wrench is not consistent. Therefore, the conventional assembly method can only regulate the angle range of the wrench to the female nut (15) and cannot Make each joint (1) locked in a fixed position, so that the flange (113) of the first connecting pipe (11) and the flange (123) of the second connecting pipe (12) are pressed against the movable gasket (131) The power of) is not consistent. In practice, it has also been found that operators with greater force may cause the movable gasket (131) to wear or even deform due to the larger rotation angle of the female nut (15) by the wrench, making the joint (1) unable to be replaced after disassembly. Assembled and used, obviously there are shortcomings to be improved.

In order to improve the above shortcomings, the Republic of China Announcement No. I630073 Patent discloses a "precision connector and a method of forming a precision connector", which uses a wrench containing a strain gauge to rotate the threaded connector to make the threaded connector different The associated strain of the state is monitored, and a baseline is established, and then the wrench is further rotated to the number of revolutions desired by the user according to the signal instruction to establish a mechanical standard.

In view of the fact that the conventional assembly method of joints cannot lock each joint in a fixed position, resulting in the inconsistent force of the two connecting pipes pressing on the movable gasket, there is obviously a lack of improvement.

Therefore, the purpose of this creation is to set a scale on the fixed end nut, and set a graduated positioning collar on the rotating end nut, so that the fixed end nut and the rotating end nut of each joint can be matched. The quasi-scale is then locked in a fixed position to achieve the purpose of standardization of the joint.

In order to achieve the foregoing purpose, the present invention provides a joint positioning structure for conducting chemicals, comprising: a first coupling pipe, the first coupling pipe forming a first flange; a second coupling pipe, the second coupling pipe A second flange is formed; a washer including a movable washer, and the movable washer is arranged between the first flange and the second flange; a fixed end nut, the fixed end nut for the first The connecting pipe is passed through and forms a nut section. One end of the nut section is provided with a first scale, and a second scale is provided on the end face adjacent to the first scale; a rotating end nut, the The rotating end nut is passed through by the second connecting pipe and is screwed with the fixed end nut; and a positioning collar is sleeved on the outer ring of the rotating end nut and includes an outer ring body and an outer ring The inner ring body rotates coaxially. The outer ring body has a perforation and a ring groove, and the perforation corresponds to the shape of the outer ring of the rotating end nut. The inner ring body is fitted into the ring groove and is provided on the outer end surface of the inner ring The third scale.

Based on the above, the first scale, the second scale provided on the end face of the fixed end nut and the third scale of the positioning collar sleeved on the rotating end nut are used as the reference for the joint locking, so that the operator can screw the screw with bare hands. When the fixed end nut and the rotating end nut are combined, the inner ring body can be rotated to make the third scale correspond to the first scale, and then the rotating end nut can be rotated to the inner ring body with a wrench. The third scale corresponds to the fixed end nut The second scale of the cap can accurately determine that the joint is indeed locked, so that the fixed end nut and the rotating end nut of each joint are locked in the same position to realize the standardization of the joint and avoid the wear of the movable gasket. Affect sealing.
