Description

Technical Field

[0001] The present application relates to the technical field of semiconductor manufacturing equipment, and in particular to a hydraulic quick-connect connector fastening device. Background Art

[0002] Hydraulic quick-connect fittings are widely used in cooling systems for semiconductor manufacturing equipment due to their compact structure, easy operation, and leak-proof design. Both the male and female ends of these fittings consist of an upper and lower valve body. The upper valve body of each fitting facilitates quick insertion and removal, while the lower valve body provides a fixed connection between the fitting and the equipment piping.

[0003] In the field of semiconductor manufacturing equipment, the installation accuracy requirements between quick-connect connectors and equipment pipelines are extremely strict. For example, even a slight improper tightening between a hydraulic quick-connect connector and a pipeline may cause leakage, so any slight installation deviation may affect the quality of the final product.

[0004] However, because conventional fastening devices typically utilize cylindrical valve bodies and are not typically equipped with a screwing mechanism to prevent deformation of quick-connect fittings during installation, conventional fastening devices are unable to provide sufficiently precise tightening, leaving them unsuitable for fastening hydraulic quick-connect fittings in semiconductor manufacturing equipment.

[0005] Based on this, it is necessary to develop a new hydraulic quick-connect connector fastening device. Utility Model Content

[0033] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0034] Additionally, in the following description, specific details are provided to provide a thorough understanding of the examples, however, one skilled in the art will appreciate that the examples can be practiced without these specific details.

[0035] Currently, existing quick-connect connector technologies are primarily focused on the automotive and shipbuilding industries. For example, Chinese patent publication CN116329944 proposes an automated assembly method, system, and fixture for automotive quick-connect connectors; Chinese patent publication CN220863226U discloses another automated assembly system for automotive quick-connect connectors; and Chinese patent publication CN116214135A proposes an automated assembly device for sealing O-rings for automotive quick-connect connectors. However, these technologies do not cover the fastening and assembly of valve bodies on hydraulic quick-connect connectors, despite their essential role in the cooling systems of semiconductor manufacturing equipment.

[0036] In view of this, the inventors discovered through research and improvement exploration that: since semiconductor manufacturing equipment has extremely strict precision requirements, which are far higher than those in the automotive and shipbuilding industries, the performance requirements for quick-connect connectors are also more stringent, especially in terms of the sealing and reliability of the connectors. As a result, the existing quick-connect connector technology cannot meet the special technical requirements of the semiconductor manufacturing field for hydraulic quick-connect connectors.

[0037] Based on this, the embodiment of this specification proposes a hydraulic quick-connect connector fastening device: Figure 1 As shown, the tightening device first evenly distributes tapered pins 1 around the circumference of the hydraulic quick-connect fitting's upper valve body. Flexible bushings 2 within torsion sleeve 3 then circumferentially limit the tapered pins 1. Finally, a wrench is used to apply force to wrench position 31 of torsion sleeve 3, rotating the torsion sleeve 3 and transmitting torque to the upper valve body, thereby achieving rotational tightening of the upper valve body. Due to the deformable nature of flexible bushings 2 and the even circumferential distribution of tapered pins 1, this torque is evenly transmitted to the upper valve body, eliminating deformation of the upper valve body under torsion and significantly reducing the risk of valve body leakage due to improper tightening. This ensures the sealing and reliability of the hydraulic system, enhances the overall performance of the fitting, and improves production efficiency and quality.

[0038] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0039] like Figure 1-4 As shown, the embodiment of this specification provides a hydraulic quick-connect connector fastening device, including: a plurality of tapered pins 1, wherein the tapered pins 1 are provided with a square end 11 and a tapered pin head 12, the square end 11 is used to be embedded in the flexible bushing 2, and the tapered pin head 12 is used to be inserted into the steel ball hole 41 of the upper valve body of the hydraulic quick-connect connector, and the taper of the tapered pin head 12 matches the taper of the steel ball hole 41;

[0040] A plurality of flexible bushings 2, wherein a bushing body 21 of the flexible bushing 2 is provided with a groove 22, the groove 22 is used to accommodate the square end 11 of the tapered pin 1; the bushing body 21 is used to be embedded in the inner wall of the torsion sleeve 3;

[0041] The torsion sleeve 3 is provided with a wrench position 31 for screwing on the outside of the sleeve body 32, and an axial groove 33 and an axial rib 34 are provided on the inside of the sleeve body 32. The bottom of the axial groove 33 and the side wall of the axial rib 34 are used to make the outer wall of the bushing body 21 fit with the bottom of the axial groove 33 and the side wall of the axial rib 34 respectively when the bushing body 21 is embedded and installed.

[0042] During implementation, the tapered pin head 12 of the tapered pin 1 can be precisely inserted into the steel ball hole 41 of the upper valve body and positioned in the appropriate position, ensuring that the tapered pin head 12 is tightly fitted with the steel ball hole 41. The flexible bushing 2 is installed in the axial groove 33 on the inner side of the torsion sleeve 3, ensuring that the axial groove 33 is aligned with the groove 22 of the flexible bushing 2. The groove 22 of the flexible bushing is aligned with the square end 11 of the tapered pin, so that the square end 11 can be inserted into the groove 22 of the flexible bushing 2. A wrench or other tool is used to apply an appropriate torsional force to the wrench position 31 of the torsion sleeve 3. The torsional force is transmitted to the flexible bushing 2 through the torsion sleeve 3, and then transmitted to the square end 11 of the tapered pin 1 through the groove 22, ultimately achieving uniform tightening of the upper valve body.

[0043] It should be noted that the material of the flexible bushing 2 is flexible and can be rubber, plastic or other non-metallic materials with a certain degree of flexibility. It can return to its original shape after the tapered pin 1 applies force, ensuring that it deforms under the required torque but will not slip, thereby maintaining the tapered pin 1 in a stable position in the flexible bushing 2.

[0044] In summary, the hydraulic quick-connect connector fastening device structure composed of a flexible bushing, a torsion sleeve and a tapered pin has a simple overall structure, requires few parts, and is very convenient to install and deploy according to the position requirements of the upper valve body. The operation process is simple, which improves construction efficiency and significantly reduces the risk of valve body leakage caused by improper fastening of the valve body, thereby ensuring the sealing and reliability of the hydraulic system, enhancing the overall performance of the connector, and improving production efficiency and product quality.

[0045] In one embodiment, the two side edges of the square end 11 of the tapered pin 1 are parallel and axially parallel to the female valve body 4 to which it is fastened, which is very conducive to aligning the tapered pin and inserting it into the groove of the flexible bushing, simplifying the installation process of the tapered pin, and by keeping the side edges of the square end axially parallel to the valve body, ensuring that the tapered pin remains coaxial with the valve body during the insertion and fastening process, thereby avoiding stress concentration or damage caused by eccentricity or misalignment.

[0046] In one embodiment, the taper of the tapered pin head 12 of the tapered pin 1 is equal to the taper of the steel ball hole 41 on the female valve body 4 to which it is fastened, both being 5°.

[0047] In one embodiment, five tapered pins 1 are provided in the hydraulic quick-connect connector fastening device, and correspondingly, five flexible bushings 2 are installed in the torsion sleeve 3 to ensure that the entire upper valve body is subjected to uniform force during tightening. The square end 11 of each tapered pin 1 can be accurately embedded in the groove 22 of the corresponding flexible bushing 2, thereby achieving an efficient and uniform tightening effect.

[0048] In one embodiment, the tapered pin 1 is made of die steel, which has high strength and hardness and does not deform under the required torsional force.

[0049] In one embodiment, the flexible bushing 2 is clearance-fitted with the tapered pin 1 , and the groove 22 of the flexible bushing 2 serves as a guide groove and a limiting groove for the tapered pin 1 .

[0050] Specifically, the inner dimensions of the flexible bushing 2 are slightly larger than the outer dimensions of the tapered pin 1, leaving a certain gap between the two. This allows the tapered pin to move within the flexible bushing without becoming too loose, thus ensuring a stable fit. Furthermore, the groove 22 of the flexible bushing 2 not only serves as a guide, guiding the square end 11 of the tapered pin 1 to properly align and fit within the groove, ensuring that the tapered pin 1 moves in the correct direction during installation and tightening, thereby improving assembly accuracy and reliability, but also acts as a limiter, restricting the range of movement of the tapered pin 1 within the flexible bushing 2 and preventing it from deviating from its intended position or completely falling out of the bushing when force is applied. This ensures that the tapered pin 1 remains in the correct position throughout the tightening process.

[0051] In one embodiment, the length of the sleeve body 32 of the torsion sleeve 3 is greater than the axial distance from the steel ball hole 41 of the female valve body 4 to the plug-in port of the female valve body 4, thereby reducing sliding or displacement caused by insufficient length, achieving uniform tightening of the valve body, preventing local stress concentration and valve body deformation, and ensuring the sealing and reliability of the hydraulic system.

[0052] In one embodiment, the axial groove 33 of the torsion sleeve 3 is interference fit with the flexible bushing 2 to prevent the hydraulic quick-connect connector from being displaced or rotated under conditions of high pressure and frequent operation. Through tight fit, the gap between the axial groove 33 and the flexible bushing 2 is eliminated, thereby improving the sealing performance of the entire quick-connect connector and preventing fluid leakage.

[0053] In one embodiment, the flexible bushing 2 is fixed in the axial groove 33 by gluing.

[0054] In one embodiment, the inner diameter of the axial rib 34 of the torsion sleeve 3 is larger than the maximum outer diameter of the female valve body 4. This not only provides sufficient space to accommodate the valve body during installation so that the torsion sleeve can be smoothly mounted on the valve body, but also can adapt to valve bodies of different sizes, thereby increasing the versatility and flexibility of the fastening device.

[0055] In one embodiment, if Figure 2 As shown, the edge of the tapered pin head 12 of the tapered pin 1 is inside the square end 11;

[0056] And / or, the edge of the tapered pin head 12 is tangent to two opposite sides of the square end 11 .

[0057] In one embodiment, the limiting end 35 is located at one end of the torsion sleeve 3 and is connected to the sleeve body 32, thereby preventing the torsion sleeve 3 from moving or detaching during the fastening process and maintaining the stability of the fastening device.

[0058] In one embodiment, the limiting end 35 of the torsion sleeve 3 limits the torsion sleeve 3 at the plug-in port of the female valve body 4. During tightening or use, the limiting end 35 can prevent the torsion sleeve 3 from accidentally falling off or shifting, while simplifying the assembly process.

[0059] In one embodiment, the shape of the wrench position 31 of the torsion sleeve 3 is any one of the following shapes: hexagonal, dodecagonal. Specifically, the shape of the wrench position 31 of the torsion sleeve 3 can be designed according to actual needs.

[0060] The device provided by the utility model has a simple structure and is easy to implement. The valve body of the quick-connect female connector is tightened and installed by cooperating with the flexible bushing and the tapered pin head, so that the hydraulic female valve body 4 can be tightened under uniform torque, eliminating the valve body deformation problem caused by traditional fastening methods or devices.

[0061] In this specification, the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the embodiments described later, the description is relatively simple, and the relevant parts can be referred to the partial description of the previous embodiments.

[0062] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
