[0053] Embodiment 1

[0054] Based on the above, in the process of producing products such as integrated stoves, automobiles, and combustion furnaces that need to transport fluids through pipes, it is necessary to install joints at the ports of the pipes so that the pipes can be connected to external fluid sources and / or operating modules on the products.

[0055] This embodiment is described by taking an integrated stove as an example. The integrated stove is a kitchen appliance that integrates multiple functions such as a smoke extractor, a gas stove, a disinfection cabinet, and a storage cabinet. The integrated stove delivers external gas to the burner through an air intake pipe. Figure 1 and Figure 2 As shown, the air inlet pipe includes a pipeline 110 and a joint 120 installed at the end of the pipeline 110 , and the pipeline 110 is connected to an external gas source and / or a burner through the joint 120 .

[0056] See also Figures 3 to 20 , and combined with Figure 1 and Figure 2 In this embodiment, a pipe assembly device is provided, which is used to assemble a joint 120 at the port of a pipe 110. The pipe assembly device includes a first clamping mechanism 220, which is configured to clamp and position the pipe 110, thereby ensuring that the position of the pipe 110 remains unchanged during the subsequent assembly of the joint 120.

[0057] In addition to the first clamping mechanism 220, the pipe assembly device also includes a frame, a reaming mechanism 230, a plug-in mechanism 240 and a crimping machine 250, wherein the reaming mechanism 230 is installed on the frame and includes a reaming plunger 231 and a first driving member 232. The reaming plunger 231 has a first end and a second end at its two axial ends, respectively. The first end is formed with a reaming portion 2311. The diameter of the reaming portion 2311 gradually decreases from a side close to the second end to a side away from the second end, and the diameter of the side of the reaming portion 2311 close to the second end is greater than the diameter of the port. The reaming plunger 231 can be directly opposite to the port along its axial direction. The first driving member 232 is configured to drive the reaming plunger 231 to move along its axial direction, so that the reaming portion 2311 of the reaming plunger 231 can be inserted into the port of the pipe 110 and expand the diameter of the port of the pipe 110, thereby achieving reaming of the end of the pipe 110. The first driving member 232 may be a linear driving structure such as a pneumatic cylinder or an electric cylinder, and this is not specifically limited in this embodiment.

[0058] It can be understood that in this embodiment, the reaming plunger 231 can flare the end of the pipe 110 by 60°. Of course, in other optional embodiments, the reaming plunger 231 can also flare the end of the pipe 110 at other angles, and this embodiment does not impose specific limitations on this.

[0059] In addition, the plug-in mechanism 240 is also installed on the frame and includes a push rod 241 and a second drive member 242. One end of the push rod 241 is sleeved with a connector 120, that is, the connector 120 to be assembled is first installed on the end of the push rod 241. It is worth noting that in this embodiment, the connector 120 is sleeved on the end of the push rod 241. Of course, in other optional embodiments, the end of the push rod 241 can be set as a sleeve-type structure, so that the end of the push rod 241 can be sleeved on the outer periphery of the connector 120, thereby making one end of the push rod 241 sleeved with the connector 120. This is not specifically limited in this embodiment.

[0060] Based on the above, the push rod 241 can be aligned with the port along its axial direction, and the second driving member 242 is configured to drive the push rod 241 to move along its axial direction, so as to insert the joint 120 into the pipe 110 through the port. Specifically, the reaming plunger 231 first faces the port along its axial direction and moves toward the port along its axial direction, so as to expand the end of the pipe 110. After that, the reaming plunger 231 is withdrawn from the pipe 110, and the push rod 241 faces the port along its axial direction and moves toward the port along its axial direction, so as to insert the joint 120 into the pipe 110 through the port. Among them, the second driving member 242 can be selected as a linear drive structure such as a cylinder or an electric cylinder, and there is no specific limitation on this in this embodiment.

[0061] Furthermore, the crimping machine 250 is also installed on the frame and is configured to crimp the pipe 110 at a portion where the pipe 110 overlaps with the joint 120 in a radial direction after the joint 120 is installed in the pipe 110. Specifically, after the push rod 241 inserts the joint 120 into the port, the push rod 241 moves away from the port along its axial direction, thereby separating the push rod 241 and the joint 120, wherein the joint 120 remains in the pipe 110, and the push rod 241 is detached from the joint 120, thereby installing the joint 120 into the pipe 110, and then the crimping machine 250 crimps the pipe 110 at a portion where the pipe 110 overlaps with the joint 120 in a radial direction, thereby firmly crimping the joint 120 in the pipe 110.

[0062] It is worth mentioning that a sealing ring 121 is sleeved on the joint 120 for sealing between the joint 120 and the pipe 110. The sealing ring 121 can increase the friction between the joint 120 and the inner wall of the pipe 110. In addition, the joint 120 in this embodiment is also provided with a transverse structure 122 for further increasing the friction between the joint 120 and the inner wall of the pipe 110. Therefore, after the push rod 241 inserts the joint 120 into the port and the push rod 241 moves away from the port along its axial direction, the push rod 241 and the joint 120 can be separated smoothly.

[0063] Based on the above, this embodiment positions the pipe 110 through the first clamping mechanism 220, and sequentially performs pipe 110 flaring operation, joint 120 insertion operation and crimping operation through the reaming mechanism 230, the plug-in mechanism 240 and the crimping machine 250, so that the joint 120 is firmly assembled to the port of the pipe 110 by insertion, thereby improving the pass rate of the pipe 110 after the joint 120 assembly operation is completed. Moreover, during the assembly process, the coating layer on the surface of the pipe 110 and / or the joint 120 will not be damaged, so there is no need to re-surface the pipe 110 and / or the joint 120, thereby avoiding affecting the production efficiency of the product.

[0064] It can be understood that in this embodiment, the product mentioned above is an integrated stove, that is, the pipe assembly device is used to assemble the joint 120 at the end of the pipe 110 during the production process of the integrated stove, thereby obtaining the air intake pipe. Of course, in other optional embodiments, the pipe assembly device can also be used to assemble the joint 120 at the end of the corresponding pipe 110 during the production process of products such as automobiles and combustion stoves. In this embodiment, there is no specific limitation on the application scenario of the pipe assembly device.

[0065] In addition, it is worth mentioning that the crimping machine 250 includes a plurality of pressing blocks 251, and the plurality of pressing blocks 251 are arranged around the first axis. Since the specific structure and working principle of the crimping machine 250 are prior arts, they will not be described in detail in this embodiment.

[0066] Preferably, a push portion 2312 is provided on the side of the reaming portion 2311 away from the second end, the push portion 2312 is coaxial with the reaming portion 2311, and the outer diameter of the push portion 2312 is equal to the inner diameter of the pipe 110. When the reaming plunger 231 moves along its axial direction toward the port, the push portion 2312 first extends into the pipe 110, thereby pushing against the process ribs on the inner wall of the pipe 110, and then squeezing out the process ribs on the pipe 110 close to the port, that is, in this embodiment, the process ribs on the pipe 110 close to the port can be eliminated by the push portion 2312, thereby ensuring that the subsequent joint 120 can be smoothly inserted into the pipe 110.

[0067] In addition, if Figure 1 As shown, in this embodiment, the pipeline 110 is provided with two ports, and the two ports are respectively a first port 111 and a second port 112 for explanation.

[0068] Please continue reading Figures 3 to 20 Based on the above, in this embodiment, the frame, the first clamping mechanism 220, the hole expanding mechanism 230, the plug-in mechanism 240 and the crimping machine 250 form an assembly module, and the pipeline assembly device includes two assembly modules, that is, all assembly modules include the frame, the first clamping mechanism 220, the hole expanding mechanism 230, the plug-in mechanism 240 and the crimping machine 250. The two assembly modules can respectively assemble the joints 120 on the two ports, and the first clamping mechanism 220 can clamp the portion of the pipeline 110 close to the port.

[0069] Taking two assembly modules, namely the first assembly module and the second assembly module, as an example, in this embodiment, the first assembly module and the second assembly module are respectively used to assemble the joint 120 at the first port 111 and the second port 112 of the pipe 110. Specifically, for the first assembly module, the first clamping mechanism 220 of the first assembly module clamps the portion of the pipe 110 close to the first port 111, the reaming plunger 231 of the first assembly module can be directly opposite to the first port 111 along its axial direction, and is used to expand the end of the pipe 110 where the first port 111 is formed, the push rod 241 of the first assembly module can be directly opposite to the first port 111 along its axial direction, and is used to insert the joint 120 into the pipe 110 through the first port 111, and the crimping machine 250 of the first assembly module is used to firmly crimp the joint 120 inserted into the pipe 110 from the first port 111 into the pipe 110. As for the second assembly module, the first clamping mechanism 220 of the second assembly module clamps the portion of the pipe 110 close to the second port 112, the reaming plunger 231 of the second assembly module can be opposite to the second port 112 along its axial direction, and is used to flare the end of the pipe 110 where the second port 112 is formed, the pushing rod 241 of the second assembly module can be opposite to the second port 112 along its axial direction, and is used to insert the connector 120 into the pipe 110 through the second port 112, and the crimping machine 250 of the second assembly module is used to firmly crimp the connector 120 inserted into the pipe 110 from the second port 112 into the pipe 110.

[0070] Based on the above, in this embodiment, the joints 120 can be assembled at the two ports of the pipeline 110 at the same time, thereby improving production efficiency.

[0071] It can be understood that in other optional embodiments, the number of ports of the pipe 110 can also be set to be greater than two, and accordingly, the number of assembly modules included in the pipe assembly device can also be correspondingly set to be greater than two. For example, the pipe 110 can also be provided with three, four, five or other numbers of ports, and accordingly, the pipe assembly device can also be correspondingly set to include three, four, five or other numbers of assembly modules, so as to assemble the joint 120 at all ports of the pipe 110 at the same time. In this embodiment, there is no specific limitation on the number of ports of the pipe 110 and the number of assembly modules included in the pipe assembly device.

[0072] Furthermore, the pipeline assembly device also includes a base 300, one of the frame and the base 300 is provided with a first positioning block (not shown in the figure), and the other of the frame and the base 300 is provided with a first positioning groove (not shown in the figure), and the first positioning block is accommodated in the first positioning groove, thereby positioning the frame on the base 300.

[0073] Preferably, in this embodiment, for any assembly module, the axial direction of the reaming plunger 231 is parallel to the axial direction of the push rod 241, the frame includes a first drag plate 211, a second drag plate 212 and a third drag plate 213, the second drag plate 212 is slidably connected to the first drag plate 211 along a direction perpendicular to the axial direction of the reaming plunger 231, the third drag plate 213 is slidably connected to the second drag plate 212 along a direction parallel to the axial direction of the reaming plunger 231, and the reaming mechanism 230, the plug-in mechanism 240 and the crimping machine 250 are all installed on the third drag plate 213.

[0074] Taking the axis of the reaming plunger 231 as the second axis and the axis of the push rod 241 as the third axis as an example, in this embodiment, the second carriage 212 can slide in a direction perpendicular to the axial direction of the reaming plunger 231, so that the second axis, the third axis and the first axis coincide with the axis of the port in sequence. It can be understood that when the first axis coincides with the axis of the port, the third carriage 213 can slide toward the pipe 110 in a direction parallel to the axial direction of the reaming plunger 231, so that the pipe 110 at a position where it coincides with the joint 120 in its radial direction extends between the plurality of pressing blocks 251, thereby allowing the crimping machine 250 to crimp the pipe 110 at a position where it coincides with the joint 120 in its radial direction. Afterwards, the third carriage 213 can slide away from the pipe 110 in a direction parallel to the axial direction of the reaming plunger 231, so that the pipe 110 at a position where it coincides with the joint 120 in its radial direction is pulled out from between the plurality of pressing blocks 251. It is understandable that when the second carriage 212 slides in a direction perpendicular to the axial direction of the reaming plunger 231 to make the first axis coincide with the axis of the port, the staff can place a new connector 120 on the push rod 241 to wait for the next assembly of the connector 120 to another pipe 110.

[0075] Based on the above, in the present embodiment, the first positioning groove is opened on the base 300, and the first positioning block is arranged on the first drag plate 211, the first drag plate 211 is provided with a plurality of first slide rails 2111 extending in a direction perpendicular to the axial direction of the reaming plunger 231, the second drag plate 212 is slidably connected to the first slide rail 2111, the second drag plate 212 is provided with a plurality of second slide rails 2121 extending in a direction parallel to the axial direction of the reaming plunger 231, and the third drag plate 213 is slidably connected to the second slide rail 2121.

[0076] Furthermore, the pipeline assembly device also includes a third driving member 2112, which is fixedly connected to the first carriage 211 and is configured to drive the third carriage 213 to move in a direction parallel to the axial direction of the reaming plunger 231. The third carriage 213 is provided with a slide groove 2131, which extends in a direction parallel to the axial direction of the reaming plunger 231. The movable end 21121 of the third driving member 2112 is clamped in the slide groove 2131 and can slide relative to the slide groove 2131 along the extension direction of the slide groove 2131. Specifically, the slide groove 2131 is provided on the third carriage 213. The groove 2131 is a T-shaped groove, and the movable end 21121 of the third driving member 2112 is clamped in the T-shaped groove. The movable end 21121 of the third driving member 2112 can slide relative to the slide groove 2131 along the extension direction of the slide groove 2131, and when the movable end 21121 of the third driving member 2112 is extended and retracted in a direction parallel to the axial direction of the reaming plunger 231, the movable end 21121 of the third driving member 2112 will not move out of the slide groove 2131, so that the third carriage 213 can be driven to move in a direction parallel to the axial direction of the reaming plunger 231. Among them, the third driving member 2112 can be selected as a linear driving structure such as a cylinder or an electric cylinder, which is not specifically limited in this embodiment.

[0077] Of course, in other optional embodiments, the third driving member 2112 may also be fixedly connected to the second carriage 212, and this is not specifically limited in the present embodiment.

[0078] In addition to the third driving member 2112, the pipeline assembly device also includes a fourth driving member 2113, which is used to drive the second carriage 212 to slide in a direction perpendicular to the axial direction of the reaming plunger 231. The fourth driving member 2113 is installed on the first carriage 211. The fourth driving member 2113 is a linear driving structure composed of a motor and a screw rod. Of course, in other optional embodiments, the fourth driving member 2113 can also be a linear driving structure such as a cylinder or an electric cylinder, and this is not specifically limited in this embodiment.

[0079] Furthermore, in the present embodiment, for the first assembly module, the first clamping mechanism 220 of the first assembly module is installed on the base 300, and for the second assembly module, the first clamping mechanism 220 of the second assembly module is installed on the first drag plate 211 of the frame. Specifically, the base 300 and the first drag plate 211 of the frame of the second assembly module are both provided with a second positioning block 2114, the first clamping mechanism 220 includes a mounting seat 221, and the mounting seat 221 is provided with a second positioning groove 2212, and the second positioning block 2114 is accommodated in the second positioning groove 2212, so as to position the first clamping mechanism 220.

[0080] Of course, other optional embodiments may also be: the first clamping mechanism 220 of the first assembly module is installed on the first drag plate 211 of the frame, and the first clamping mechanism 220 of the second assembly module is installed on the base 300, or the two first clamping mechanisms 220 are respectively installed on the first drag plates 211 of the two frames, or the two first clamping mechanisms 220 are both installed on the base 300. This embodiment does not make specific restrictions on this.

Specifically, in this embodiment, the mounting seat 221 includes a seat body 2213 and a second clamping block 2214, the second clamping block 2214 is installed on the seat body 2213, and the first groove 2211 is provided on the second clamping block 2214, wherein one of the seat body 2213 and the second clamping block 2214 A third positioning block 22131 is provided, and the other of the seat body 2213 and the second clamping block 2214 is provided with a third positioning groove 22141. The third positioning block 22131 is accommodated in the third positioning groove 22141, thereby positioning the second clamping block 2214. A first driving part 2215 is installed on the mounting seat 221. The first driving part 2215 is used to drive the first clamping block 222 to move toward or away from the mounting seat 221. When the first driving part 2215 drives the first clamping block 222 to move toward the mounting seat 221, the first groove 2211 and the second groove 2221 can enclose and make the first clamping block 222 and the mounting seat 221 embrace the pipe 110, thereby clamping and positioning the pipe 110. Among them, the first driving part 2215 can be selected as a linear driving structure such as a cylinder or an electric cylinder, which is not specifically limited in this embodiment.

[0082] It is worth noting that, in this embodiment, the first clamping block 222 is located above the mounting seat 221, and the staff can first place the pipe 110 in the first groove 2211, and then the first driving part 2215 drives the first clamping block 222 to move toward the mounting seat 221, so that the first groove 2211 and the second groove 2221 are surrounded. Of course, in other optional embodiments, the first clamping block 222 and the mounting seat 221 can also be arranged in the horizontal direction, which is not specifically limited in this embodiment.

[0083] In addition, it is worth mentioning that the first groove 2211 and the second groove 2221 are both contoured grooves. After the first groove 2211 and the second groove 2221 are combined, the curved portion of the pipe 110 is encircled between the first clamping block 222 and the mounting seat 221, thereby positioning the pipe 110 more stably.

[0084] It can be understood that the portion of the pipe 110 that overlaps with the joint 120 in the radial direction is exposed to the first clamping mechanism 220. In this embodiment, in addition to the first clamping mechanism 220, the pipe assembly device in this embodiment also includes a second clamping mechanism 260, which is installed on the third carriage 213.

Among them, the second driving part 263 can be selected as a linear driving structure such as a cylinder or an electric cylinder, which is not specifically limited in this embodiment.

[0085] When the second axis coincides with the axis of the port, the third carriage 213 can slide toward the pipe 110 in a direction parallel to the axial direction of the reaming plunger 231, so that the portion of the pipe 110 close to the port and exposed to the first clamping mechanism 220 extends between the first clamping block 261 and the second clamping block 262 of the second clamping mechanism 260 corresponding to the reaming mechanism 230, thereby enabling the first clamping block 261 and the second clamping block 262 to clamp the portion of the pipe 110 close to the port and exposed to the first clamping mechanism 220, thereby further ensuring that the subsequent reaming plunger 231 can be smoothly inserted into the pipe 110. Moreover, when the reaming operation of the pipe 110 is completed, the third carriage 213 can slide away from the pipe 110 in a direction parallel to the axial direction of the reaming plunger 231, so that the portion of the pipe 110 close to the port and exposed to the first clamping mechanism 220 is pulled out from between the first clamping block 261 and the second clamping block 262.

[0086] When the third axis coincides with the axis of the port, the third carriage 213 can slide toward the pipe 110 in a direction parallel to the axial direction of the reaming plunger 231, so that the portion of the pipe 110 near the port and exposed to the first clamping mechanism 220 extends between the first clamping block 261 and the second clamping block 262 of the second clamping mechanism 260 corresponding to the plug-in mechanism 240, thereby enabling the first clamping block 261 and the second clamping block 262 to clamp the portion of the pipe 110 near the port and exposed to the first clamping mechanism 220, thereby further ensuring that the subsequent joint 120 can be smoothly inserted into the pipe 110. Moreover, when the insertion operation of the joint 120 is completed, the third carriage 213 can slide away from the pipe 110 in a direction parallel to the axial direction of the reaming plunger 231, so that the portion of the pipe 110 near the port and exposed to the first clamping mechanism 220 is pulled out from between the first clamping block 261 and the second clamping block 262.

[0087] Furthermore, the reaming mechanism 230 also includes a first slider 233, the reaming plunger 231 is installed on the first slider 233, and the first slider 233 is slidably connected to the frame. Specifically, a third slide rail 2132 is provided on the third drag plate 213, and the third slide rail 2132 extends in a direction parallel to the axial direction of the reaming plunger 231. The first slider 233 is slidably connected to the third slide rail 2132. The first driving member 232 can drive the first slider 233 to slide along the axial direction of the reaming plunger 231, thereby ensuring that the reaming plunger 231 can stably move along its axial direction.

[0088] Furthermore, the reaming plunger 231 is detachably connected to the first slider 233 , so that the reaming plunger 231 can be replaced when the reaming plunger 231 is worn due to long-term operation.

[0089] It can be understood that the expansion plunger 231 can be detachably connected to the first slider 233 by bolt connection, pin connection, etc., and there is no specific limitation on this in the present embodiment.

[0090] In addition, the plug-in mechanism 240 also includes a second slider 243, the push rod 241 is installed on the second slider 243, and the second slider 243 is slidably connected to the frame. Specifically, a fourth slide rail 2133 is provided on the third drag plate 213, and the fourth slide rail 2133 extends in a direction parallel to the axial direction of the expansion plunger 231. The second slider 243 is slidably connected to the fourth slide rail 2133, and the second driving member 242 can drive the second slider 243 to slide along the axial direction of the push rod 241, thereby ensuring that the push rod 241 can stably move along its axial direction.

[0091] Furthermore, the push rod 241 is detachably connected to the second slider 243 , so that the push rod 241 can be replaced when the push rod 241 is damaged due to an accident.

[0092] It can be understood that the push rod 241 can be detachably connected to the second sliding block 243 by bolt connection, pin connection or other connection methods, and this is not specifically limited in the present embodiment.
