[0036] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments, in conjunction with the accompanying drawings, provide a detailed description of a sealing connection pipe processing device of the present invention.

[0037] <Example>

[0038] Figure 1 This is a three-dimensional structural schematic diagram of the sealing connection pipe processing device in an embodiment of the present invention.

[0039] Figure 2 This is a schematic diagram of the structure of the sealing connecting pipe in an embodiment of the present invention. Figure 1 .

[0040] Figure 3 This is a schematic diagram of the structure of the sealing connecting pipe in an embodiment of the present invention. Figure 2 .

[0041] like Figure 1 , Figure 2 as well as Figure 3 As shown, this embodiment provides a sealing connection pipe processing device 100 for installing two nuts 3 in the two nut mounting holes 3 of the connection pipe body 2 and installing a sealing ring in the sealing ring groove of the connection pipe body 2. The sealing connection pipe processing device 100 includes a connection pipe body fixing mechanism 10, a nut mounting mechanism 20, a sealing ring mounting mechanism 30, and a support plate 40.

[0042] Figure 4 This is a schematic diagram of the structure of the fixed mold in an embodiment of the present invention.

[0043] The connecting pipe body fixing mechanism 10 is mounted on the support plate 40, which can fix the connecting pipe body 2 and make the nut mounting hole 4 face the vertical direction. It includes a fixing mold 11 and a clamping part 12. Figure 4 As shown, the fixing mold 11 includes a first groove 111 and a second groove 112. The first groove 111 is adapted to the portion of the bent pipe portion 2c of the connecting pipe body 2 located below the nut mounting portion 2a. The second groove 112 is adapted to the joint portion 2d of the connecting pipe body 2. The first groove 111 and the second groove 112 can fix the bent pipe portion 2c and the joint portion 2d. In this embodiment, the first groove 111 is also provided with mold holes 1111 and mold arc edges 1112 corresponding one-to-one with the two nut mounting holes 4. The mold holes 1111 and the mold arc edges 1112 can reserve machining positions for the nut installation process.

[0044] Figure 5 This is a schematic diagram of the pressing part in an embodiment of the present invention.

[0045] Figure 6 This is a schematic diagram of the pressure head in an embodiment of the present invention.

[0046] like Figure 5 As shown, the clamping part 12 is located behind the fixed mold 11, and includes a clamping assembly 121 and a clamping drive assembly 122. Figure 6 As shown, the clamping assembly 121 includes a rotating rod 1211 and a pressure head 1212. One end of the rotating rod 1211 is fixed to the support plate 40, and the other end has a connecting hole. One end of the pressure head 1212 has an arc-shaped clamping block 12121, which is adapted to the sealing ring mounting part 2b. The other end of the pressure head 1212 has a cylindrical flange 12122, which is disposed in the connecting hole of the rotating rod 1211, so that the pressure head 1212 is rotatably connected to the other end of the rotating rod 1211. A first driving hole 12123 is also provided on the pressure head 1212.

[0047] Figure 7 This is a schematic diagram of the structure of the pressing part pressing the sealing ring mounting part in an embodiment of the present invention.

[0048] The clamping drive assembly 122 includes a clamping cylinder 1221 and a clamping drive rod 1222. The clamping cylinder 1221 is mounted on a support plate. One end of the clamping drive rod 1222 is connected to the clamping cylinder 1221 and extends and retracts under the drive of the clamping cylinder 1221. The other end of the clamping drive rod 1222 has a second drive hole. The clamping drive rod 1222 is connected to the pressure head 1212 via a shaft connection passing through the second drive hole and the first drive hole 12123. In this embodiment, the clamping drive rod 1222 extends and retracts under the drive of the clamping drive assembly 122, thereby causing the pressure head 1212 to rotate around the connecting hole of the rotating rod 1211, thereby abutting against the top of the nut mounting part. Figure 7 As shown, the plugging nut mounting hole 4 on the nut mounting part 2a of the pressure head 1212 can limit the nut's position during subsequent nut installation. Furthermore, a certain gap is left between the pressure head 1212 and the sealing ring mounting part 2b, providing a machining space for the subsequent sealing ring installation process. In this embodiment, the rotational clamping method of the clamping part 12 fully utilizes the equipment layout, enhances structural compactness, and does not affect the subsequent nut and sealing ring installation process.

[0049] The nut mounting mechanism 20 includes at least one nut feeding part 21 and a nut mounting part 22. In this embodiment, the connecting pipe body 2 has two nut mounting holes 4, so the number of nut feeding parts 21 is two.

[0050] Figure 8 This is a schematic diagram of the nut feeding section in an embodiment of the present invention. Figure 1 .

[0051] Figure 9 This is a schematic diagram of the nut feeding section in an embodiment of the present invention. Figure 2 .

[0052] Figure 10 This is a cross-sectional view of the feeding trough along the pushing direction in an embodiment of the present invention.

[0053] Figure 11 yes Figure 8 A magnified view of part A in the middle.

[0054] like Figure 8 and Figure 9 As shown, two nut feeding parts 21 are mounted on the support plate 40 and are located on both sides of the fixed mold 11, including a feeding guide rail 211, a feeding slider 212, a pushing guide rail 213, a pushing slider 214, and a nut pushing drive unit 215.

[0055] The feeding guide 211 has a feeding groove 2111 capable of accommodating multiple nuts 3. The cross-section of the feeding groove 2111 along the direction of pushing the nuts is adapted to the axial cross-section of the nuts 3. The nuts 3, such as... Figure 10 The nut 3 is placed flat in the feeding groove 211 as shown. The limiting groove extending outward from the bottom of the feeding groove 2111 ensures that the nut 3 remains flat during the pushing process, preventing it from rolling and affecting the installation of the nut 3. A pressing hole 2112 is provided at one end of the feeding guide rail 211 near the fixed mold 11, such as... Figure 11 As shown, the press-in hole 2112 is sized and coaxial with the mold hole 1111 and the arc-shaped edge 1112 of the mold. The press-in hole 2112 is located directly below the nut mounting hole 4 of the connecting tube body 2 on the fixed mold 11. The other end of the feeding guide rail 211 away from the press-in hole 2112 has a discharge port 2113, which is connected to the feeding groove 2111. Nuts 3 can be added to the feeding groove 2111 through the discharge port. In this embodiment, the discharge port 2113 is formed by a notch formed by the different lengths of the feeding guide rail 211.

[0056] The feeding slider 212 is adapted to the feeding trough 2111. The feeding slider 212 is set in the feeding trough 2111 and is connected to the pushing slider 214.

[0057] The push guide rail 213 is parallel to the feeding guide rail 211 and is located on the outside of the feeding guide rail 211. The push slider 214 is adapted to the push guide rail 213, is located on the push guide rail 213, and is connected to the nut push drive unit 215.

[0058] The nut pushing drive assembly 215 includes a nut pushing drive cylinder 2151 and a nut pushing drive rod 2152. The nut pushing drive cylinder 2151 is mounted on the support plate 40. The nut pushing drive rod 2152 is connected to the nut pushing drive cylinder 2151 and can extend and retract under the action of the nut pushing drive cylinder 2151. The nut pushing drive rod 2152 is connected to the pushing slider 214.

[0059] Figure 12 This is a schematic diagram of the nut mounting portion in an embodiment of the present invention.

[0060] Figure 13 This is a schematic diagram of the structure in an embodiment of the present invention, showing the mounting rod disposed in the press-in hole.

[0061] Figure 14 yes Figure 13 A magnified view of part B in the middle section.

[0062] like Figure 12As shown, the nut mounting part 22 is located below the support plate 40 and includes two mounting rods 221, a connecting rod 222, and a mounting drive unit 223. The diameter of the mounting rods 221 is smaller than the inner diameter of the press-in hole 2112, such as... Figure 13 and Figure 14 As shown, the mounting rod 221 is arranged vertically, and one end passes through the press-in hole 2112 at one end of the feeding guide rail 211. The connecting rod 222 can connect the other end of the two mounting rods 221 away from the nut mounting hole 4.

[0063] The installation drive unit 223 includes a second cylinder 2331 and a second drive rod 2332. The second cylinder 2331 is mounted on the support plate 40, and the second drive rod 2332 is connected to the second cylinder 2331 and can be raised and lowered under the drive of the second cylinder 2331. The connecting rod 222 is connected to the second drive rod 2332. Therefore, the installation drive unit 223 can drive the connecting rod 222 to move vertically, thereby causing the two installation rods 221 to move vertically within the pressing hole 2112, so that the installation rods 221 press the nut 3 into the nut mounting hole 4.

[0064] Figure 15 This is a schematic diagram of the sealing ring mounting mechanism in an embodiment of the present invention.

[0065] Figure 16 This is a schematic diagram of the structure in an embodiment of the present invention, showing the separation of the supporting part from the main body of the connecting pipe.

[0066] like Figure 15 and Figure 16 As shown, the sealing ring installation mechanism 30 is mounted on the support plate 40 and located above the connecting pipe body fixing mechanism 10, and includes a spreading part 31, a pushing part 32 and a positioning part 33.

[0067] The opening portion 31 includes multiple opening members 311 and an opening drive unit 312. The multiple opening members 311 are interconnected in an openable and closable manner. In this embodiment, there are four opening members 311, which are arc-shaped. When the four opening members 311 are combined, they form a cylindrical shape. At this time, the diameter of the opening portion 31 matches the sealing ring. The opening drive unit 312 can drive the multiple opening members 311 to open, thereby increasing the inner diameter of the sealing ring.

[0068] The pushing unit 32 includes a pushing plate 321, a transmission plate 322, two transmission rods 323, and a sealing ring pushing drive unit 324. In this embodiment, the pushing plate 321 has a through hole and two first connecting holes. The diameter of the through hole is adapted to the opening of the multiple supporting members 311. The pushing plate 321 is sleeved on the outside of the multiple supporting members 311 through the through hole. The transmission plate 322 has two second connecting holes that correspond one-to-one with the first connecting holes. The two ends of each transmission rod 323 are respectively disposed in the first connecting hole and the second connecting hole, which can connect the transmission plate 322 and the pushing plate 321. The sealing ring pushing drive unit 324 is connected to the transmission plate 322 and can drive the transmission plate 322 to reciprocate, thereby driving the pushing plate to move along the surface of the multiple supporting members 311, thereby pushing the sealing ring from the supporting members 311 to the sealing ring groove of the sealing ring mounting part 2b.

[0069] The positioning part 33 includes a fixed plate 331 and a rotary drive unit 332. The fixed plate 331 has a transmission hole through which the transmission rod 323 passes. The spreading drive unit 312 and the sealing ring pushing drive unit 324 are both mounted on the fixed plate 331. The rotary drive unit 332 is connected to the fixed plate 331 and can drive the fixed plate 331 to rotate, thereby rotating the spreading part 31 and the pushing part 32. This causes the spreading part 31 to abut against or separate from the sealing ring mounting part 2b with the sealing ring groove on the connecting pipe body 2. When separated, [the following text appears to be unrelated and possibly a separate sentence fragment:] ... Figure 16 As shown, when the expansion part 31 separates from the sealing ring mounting part 2b, the sealing ring is fitted onto the expansion part 31, and the push plate 321 can support the sealing ring to prevent the sealing ring from falling off and causing the expansion part 31 to be unable to increase the inner diameter of the sealing ring.

[0070] Figure 17 This is a schematic diagram of the structure of the camera and camera bracket in an embodiment of the present invention.

[0071] The sealing connection pipe processing device 100 provided in this embodiment also includes a detection device 50, which includes a camera 51, a camera bracket 52, and an image analysis unit. For example... Figure 17 As shown, the camera 51 is aligned with the connecting pipe body 2 via the camera bracket 52, enabling it to capture images of the connecting pipe body 2 after the installation of the nut 3 and the sealing ring. The image analysis unit includes a computer, which can analyze the images captured by the camera 51 to evaluate the processing quality of the sealing connecting pipe 1.

[0072] Figure 18 This is a flowchart of the sealing connection pipe processing method in an embodiment of the present invention.

[0073] This embodiment also provides a method for processing a sealing connection pipe. The following example uses a connection pipe body 2 as a case study. Figures 1-18 This embodiment describes the processing method for the sealing connection pipe.

[0074] Step S1: Fix the connecting pipe body 2 using the connecting pipe body fixing mechanism 10;

[0075] Step S2: The nut 3 is pushed to the bottom of the nut mounting hole 4 by the nut feeding part 21, and the nut 3 is pressed and installed in the nut mounting hole 4 by the nut mounting part 22.

[0076] Step S3: The sealing ring is fitted onto the expansion part 31, and the inner diameter of the sealing ring is increased by the expansion part 31;

[0077] In step S4, the positioning part 33 brings the spreading part 31 into contact with the end of the connecting pipe body 2 that has a sealing ring groove, and the pushing part 32 pushes the sealing ring into the sealing ring groove.

[0078] Step S5: Use camera 51 to capture an image of the sealed connection pipe 1 after installation, and upload the image to a computer for analysis and evaluation.

[0079] In this embodiment, step S1 includes the following sub-steps:

[0080] Step S1-1: Fix the bent part 2c and the joint part 2d of the connecting pipe body 2 by fixing the first groove 111 and the second groove 112 of the fixing mold 11;

[0081] In step S1-2, the pressure head 121 is driven by the pressure drive unit 122 to abut against the nut mounting part of the connecting pipe body 2, thereby pressing the connecting pipe body 2.

[0082] In this embodiment, step S2 includes the following sub-steps:

[0083] Step S2-1: The nut pushing drive unit 215 drives the pushing slider 213 to slide, which in turn drives the feeding slider 212 to push the nuts 3 in the feeding groove 2111, so that the two nuts 3 reach the two pressing holes 2112 at one end of the two feeding guide rails 211.

[0084] In step S2-2, the connecting rod 222 is driven to move vertically by the installation drive unit 223, which in turn drives the two installation rods 221 to move vertically in the pressing hole 2112, thereby pressing the nut 3 into the nut installation hole 4.

[0085] During the above installation process, the feeding groove 2111 can accommodate multiple nuts 3. In this embodiment, the two feeding grooves 2111 on both sides of the fixed mold 11 can each accommodate more than ten nuts 3, which can be added at once through the discharge port 2113, reducing the number of times nuts 3 need to be added and improving processing efficiency.

[0086] During the above installation process, only the actions of placing and removing the connecting pipe body 2 and placing the nut 3 require manual operation; the rest of the process is completed automatically, resulting in high processing efficiency.

[0087] The role and effect of the embodiments

[0088] According to the sealing connection pipe processing apparatus provided by the present invention, a connecting pipe body fixing mechanism can fix the connecting pipe body, a nut mounting mechanism is disposed below the connecting pipe body fixing mechanism, including at least one nut feeding part and a nut mounting part, and a sealing ring mounting mechanism is disposed above the connecting pipe body fixing mechanism, including a spreading part and a pushing part. The nut feeding part can push the nut to the nut mounting part below the nut mounting hole of the connecting pipe body, and the nut mounting part can press the nut into the nut mounting hole. The sealing ring is sleeved on the spreading part, which passes through the pushing part, which is disposed on the positioning part. The spreading part can spread the sealing ring open, increasing the inner diameter of the sealing ring, and the pushing part can push the sealing ring with the increased inner diameter from the spreading part into the sealing groove. The present invention also provides a sealing connection pipe processing method. Using the above-described sealing connection pipe processing apparatus, the nut and sealing ring can be efficiently installed in the nut mounting hole and sealing ring groove of the connecting pipe body, and the consistency of the processed products can be guaranteed. Therefore, the sealing connection pipe processing device and method provided by the present invention have the characteristics of simple structure, simple method, high processing efficiency, greater safety and high product consistency.

[0089] Furthermore, the feeding guide rail in the nut feeding section has a feeding groove that can accommodate multiple nuts. Multiple nuts can be added at once through the feeding port of the feeding guide rail, which helps to further improve processing efficiency.

[0090] Furthermore, one end of each of the two mounting rods is inserted into one of the two press-in holes at one end of the two feeding guides. The mounting drive unit simultaneously drives the two mounting rods to stand upright in the press-in holes, pressing the nut into the nut mounting hole of the connecting pipe body, thus improving product consistency.

[0091] Furthermore, multiple support members are interconnected in an openable and closable manner. The support drive unit can drive the multiple support members to open, thereby increasing the diameter of the sealing rings fitted on the multiple support members. The positioning part abuts the support part against the sealing ring mounting part of the connecting pipe body, and the pushing part pushes the sealing ring from the support member to the sealing ring mounting part, which improves the installation efficiency of the sealing ring and makes it safer.

[0092] Furthermore, the fixed mold is horizontally set on the support plate, and the clamping part adopts a rotary clamping method, which can make full use of the equipment layout and enhance the structural compactness, so it will not affect the installation process of the nut and sealing ring.

[0093] Furthermore, the camera can capture images of the main body of the connecting pipe after the nuts and sealing rings are installed.
