[0040] The beneficial technical effects of the present invention are:

[0041] 1. O-ring assembly and shell pressing station, automatic loading station, robot, hot plug and pressing station and I-beam assembly station. After the intercooler parts are initially assembled at the O-ring assembly and shell pressing station, the automatic loading station completes the initial transfer of the intercooler parts, and the robots sequentially transport them to the hot plug and pressing station and I-beam assembly station to complete the final assembly. The above-mentioned automated operation process improves work efficiency compared to manual assembly.

[0042] 2. Through the cooperation between the O-ring lifting cylinder and the jaw opening cylinder, the sealing ring can be quickly assembled in the intercooler, which improves the work efficiency and ensures the assembly accuracy compared with manual assembly.

[0043] 3. The setting of the pressing tool can accurately and quickly assemble the intercooler in the housing.

[0044] 4. The vibration plate transports the screws to the opening and closing cylinder of the clamping nozzle through the air pipe. The tightening gun reaches the tightening position through the tightening lifting module. The tightening motor drives the tightening gun to rotate so that the intercooler and the housing are locked by screws.

[0045] Since the locking position of the intercooler and the housing is relatively deep, it is faster than manual unlocking and can be installed in large quantities.

[0046] 5. The setting of the positioning and detection tooling not only facilitates the positioning and placement of nuts, PVC plate sleeves and I-beams, but also can detect whether the products are placed in place, ensuring that the robotic arm can accurately grasp the products.

[0047] 6. The intercooler housing, nuts, PVC plate sleeve and I-beam are clamped and transported synchronously, which improves work efficiency compared to transporting the above products one by one.

[0048] 7. Multiple cylinders are controlled separately, and the jaws of the shell clamping cylinder are in opposite directions to other jaws to avoid interference during clamping and transportation.

[0049] 8. The material picking clamp and the hot plug cooperate with each other to heat the nut and then assemble it in the intercooler housing. Similarly, before assembling the nut, the place where the nut is to be assembled is sprayed with oil through the oil spraying tool to facilitate the assembly of the nut. Similarly, the PVC plate sleeve is adsorbed and fixed by the vacuum suction head, and then the vacuum suction head is driven by the avoidance linear translation module to assemble the PVC plate sleeve in the intercooler housing.

[0050] The entire process adopts a fully automated processing method, which greatly improves work efficiency compared to traditional manual processing methods.

[0051] 9. After the I-beam is aligned by the positioning head, the I-beam is fixed to the intercooler housing by the I-beam pressing assembly to prevent the position of the I-beam from changing and ensure the subsequent assembly accuracy.

[0052] 10. The setting of the guide sleeve assembly ensures the accuracy of the rivet assembly process, avoids dislocation during the rivet assembly process, and improves the assembly efficiency.

[0053] 11. The vibrating plate, cutting assembly and rivet picking device are set up to realize the automatic loading and placement of rivets. The full process of automated processing improves efficiency compared with manual processing.

[0054] 12. The positioning head and the pressing head are connected in different ways to achieve separate processing modes for the positioning head and the pressing head, avoiding interference when the positioning head and the pressing head move synchronously.

[0055] 13. The shell pressing device and the rivet material and guide device can realize linear translation. When the rivet assembly is realized, the shell pressing device and the rivet material and guide device are moved to the designated position in the equipment to facilitate the assembly of the rivet pressing and I-beam positioning device that cannot be moved;

[0056] When the intercooler housing needs to be assembled, the housing pressing device moves to a designated position to facilitate the robot to place the intercooler housing inside the intercooler housing;

[0057] The above scheme is arranged in such a way as to avoid interference with other components in the equipment during the placement of the intercooler housing.

[0058] The above description is only an overview of the technical solution of the present invention.

[0089] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0090] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0091] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships described in the embodiments and shown in the accompanying drawings, or are directions or positional relationships in which the inventive product is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0092] like Figure 1-Figure 24 As shown, the present invention specifically relates to an intercooler shell component assembly line, which includes, based on the direction of loading, an O-ring assembly and shell pressing station 100, an automatic loading station 200, a robot 500, a hot plug and pressing station 300 and an I-beam assembly station 400. After the intercooler components are preliminarily assembled at the O-ring assembly and shell pressing station 100, the automatic loading station 200 completes the transportation of the intercooler components after the preliminary transfer, and is sequentially transported to the hot plug and pressing station 300 and the I-beam assembly station 400 by the robot 500 to complete the final assembly.

[0093] like Figure 1-Figure 7 As shown, the O-ring assembly and housing press-fitting station 100 includes an O-ring assembly station 110 and a press-fitting and tightening station;

[0094] It should be noted that a sealing ring 141 needs to be installed at one end of the intercooler 140 , and after the sealing ring 141 is assembled, the intercooler 140 needs to be assembled into the housing 150 to form a whole.

[0095] The O-ring assembly station 110 includes an O-ring workbench 111 on which the intercooler 140 is placed, and an assembly clamp mechanism for placing the sealing ring 141 is provided below the O-ring workbench 111. The assembly clamp mechanism can open the sealing ring 141 and assemble it in the intercooler 140.

[0096] A plurality of positioning posts for use with the intercooler 140 are disposed on the O-ring workbench 111 , and the intercooler 140 cannot be displaced when placed on the O-ring workbench 111 .

[0097] In addition, the O-ring workbench 111 is a shape structure used in conjunction with the assembly clamp mechanism. The personnel first places the sealing ring 141 on the assembly clamp mechanism. When the sealing ring 141 is in place, the personnel again places the intercooler 140 on the O-ring workbench 111. After the intercooler 140 is in place, the sealing ring 141 is assembled in the intercooler 140 through the assembly clamp mechanism.

[0098] The assembly jaw mechanism includes a jaw opening cylinder 114 , which is provided with a plurality of L-shaped jaws 113 . The jaw opening cylinder 114 can drive the plurality of L-shaped jaws 113 to move closer to or away from each other to open the sealing ring 141 placed on the L-shaped jaws 113 .

[0099] When the L-shaped jaws 113 are close to each other, it is convenient for personnel to place the sealing ring 141 on the L-shaped jaws 113, and the sealing ring 141 can be effectively supported by multiple L-shaped jaws 113; when the multiple L-shaped jaws 113 are away from each other, external force is applied to the sealing ring 141 by the L-shaped jaws 113 to open the sealing ring 141, so that the outer diameter of the sealing ring 141 becomes larger, so that the sealing ring 141 can be sleeved on the position to be assembled in the intercooler 140.

[0100] The plurality of L-shaped clamping jaws 113 are distributed radially along the axial direction of the clamping jaw cylinder 114 .

[0101] It also includes an O-ring lifting cylinder connected to the jaw opening cylinder 114. The O-ring lifting cylinder is provided with two groups and includes a first O-ring lifting cylinder 115 and a second O-ring lifting cylinder 116 which are connected in sequence.

[0102] Through the cooperation between the first O-ring lifting cylinder 115 and the second O-ring lifting cylinder 116 , the L-shaped clamping jaw 113 connected to the opening clamping jaw cylinder 114 can be sent into the intercooler 140 , thereby facilitating the sealing ring 141 to be sleeved in the intercooler 140 .

[0103] The jaw opening cylinder 114 is provided with a limit plate 112 used in conjunction with the L-shaped jaw 113 . The limit plate 112 is connected to the telescopic end of the first O-ring lifting cylinder 115 via a fixing rod 117 . The moving stroke of the L-shaped jaw 113 is limited by the limit plate 112 .

[0104] The assembly jaw mechanism is provided with two groups, and the two groups of the assembly jaw mechanism are connected to the slide rail through the base plate 118, and a displacement drive cylinder 119 used in conjunction with the base plate 118 is also provided on one side of the slide rail to improve the installation efficiency of the sealing ring 141 inside the intercooler 140.

[0105] The press-fitting and tightening station includes a tooling table 121 on which the shell 150 is placed, and a press-fitting tool 120 is provided on one side of the tooling table 121. The press-fitting tool 120 includes a press-fitting linear translation module 122, a press-fitting lifting module 123 provided on the press-fitting linear translation module 122, and a press-fitting plate 124 connected to the press-fitting lifting module 123. The intercooler 140 is placed in the shell 150, and the press-fitting linear translation module 122 and the press-fitting lifting module 123 drive the press-fitting plate 124 to move, so that the intercooler 140 is assembled with the shell 150.

[0106] It should be noted that the pressing linear translation module 122 and the pressing lifting module 123 are structures capable of driving the pressing plate 124 to move linearly, which are conventional structures in the prior art and therefore will not be described in detail.

[0107] First, the personnel places the shell 150 on the workbench 121, and then places the intercooler 140 with the sealing ring 141 installed in the shell 150. At this time, the intercooler 140 is not completely placed in the shell 150. The pressing linear translation module 122 and the pressing lifting module 123 cooperate with each other to drive the pressing plate 124 to reach the top of the intercooler 140, and press the intercooler 140 into the shell 150.

[0108] The tooling table 121 is provided with a plurality of positioning columns for use with the shell 150, and a limit stopper 1211 is also provided on one side of the positioning column. The shell 150 is fixed on the tooling table 121 through the cooperation between the positioning columns and the limit stopper 1211, ensuring that the shell 150 will not be displaced during the press-fitting process.

[0109] It also includes a tightening tool 130, which includes a tightening linear translation module, a tightening connection drive device arranged on the tightening linear translation module, and a tightening gun head 138 arranged on the tightening connection drive device. The intercooler 140 and the shell 150 are bolted by the tightening gun head 138.

[0110] Among them, during the process of tightening the screws, the pressing plate 124 is always in contact with the upper end surface of the intercooler 140. In addition, the pressing plate 124 is provided with a through hole used to cooperate with the tightening gun head 138. The tightening connection drive device and the tightening gun head 138 are driven to reach the specified position by tightening the linear translation module. At the same time, the tightening gun head 138 passes through the through hole into the shell 150 to fix the intercooler 140 and the shell 150 by screws.

[0111] The tightening linear translation module includes a tightening X-direction linear translation module 131, a tightening Y-direction linear translation module 132 arranged on the tightening X-direction linear translation module 131, and a tightening Z-direction linear translation module 133 arranged on the tightening Y-direction linear translation module 132. The tightening connection drive device is arranged on the tightening Z-direction linear translation module 133.

[0112] Among them, the tightening X-direction linear translation module 131, the tightening Y-direction linear translation module 132 and the tightening Z-direction linear translation module 133 are conventional structures in the prior art, which can drive the tightening gun head 138 to the specified position. Therefore, the specific structure and principle are no longer described in detail.

[0113] The tightening connection driving device includes a tightening lifting module 134 , a pressure sensor provided on the tightening lifting module 134 , and a tightening motor 136 connected to the pressure sensor. The tightening motor 136 is connected to the tightening gun head 138 via a connecting rod 1362 .

[0114] The pressure sensor and the tightening gun head 138 are respectively connected to the tightening lifting module 134 through sliders.

[0115] Among them, the pressure sensor is slidably connected to the tightening lifting module 134 through the first slider 1351, the tightening gun head 138 is slidably connected to the tightening lifting module 134 through the second slider 1381, one end of the tightening motor 136 is connected to the pressure sensor, and the other end of the tightening motor 136 is connected to the tightening gun head 138 through the connecting rod 1362.

[0116] The first sliding block 1351 is further provided with a buffer bracket 1361 used in conjunction with the tightening gun head 138 , and a connecting rod 1362 passes through the buffer bracket 1361 and is connected to the tightening gun head 138 to reduce the impact force of the tightening gun head 138 on the tightening motor 136 .

[0117] It also includes a clamping nozzle opening and closing cylinder 137 used in conjunction with the tightening gun head 138, and the clamping nozzle opening and closing cylinder 137 is connected to a vibration plate (not shown in the figure) through an air pipe 1371;

[0118] The vibration plate cooperates with the valve opening and closing cylinder 137 through the air pipe 1371 to transport the screws in the vibration plate to the bottom of the tightening gun head 138 .

[0119] Among them, the flap-clamping nozzle opening and closing cylinder 137 is connected to the tightening lifting module 134 through the fixed block 1372, and is located below the second slider 1381. The tightening gun head 138 passes through the second slider 1381, the fixed block 1372 and the flap-clamping nozzle opening and closing cylinder 137 in sequence, ensuring the stability of the tightening gun head 138 during the up and down movement.

[0120] In addition, the flap-clamping nozzle opening and closing cylinder 137 is used to control the feeding of screws. When there is already a screw in the flap-clamping nozzle opening and closing cylinder 137, the flap-clamping nozzle opening and closing cylinder 137 controls the air pipe 1371 to be closed to prevent excess screws from entering the flap-clamping nozzle opening and closing cylinder 137; when there is no screw in the flap-clamping nozzle opening and closing cylinder 137, the air pipe 1371 is controlled to be opened to facilitate the entry of the screw.

[0121] When the intercooler is fixed in the housing by screws, the intercooler and the housing can be regarded as a whole and collectively referred to as: intercooler housing.

[0122] The personnel transfer the intercooler housing and the parts to be assembled to the automatic loading station 200, and the intercooler housing and the related parts are transported to the designated location by the automatic loading station 200 to be grabbed and transported by the robot 500.

[0123] like Figure 1 , Figure 8-Figure 10As shown, the automatic loading station 200 includes a slide 210, on which a placement table 220 for positioning nuts, PVC sheet sleeves, I-beams and intercooler housings is provided;

[0124] The placement platform 220 is provided with a plurality of positioning pins used in conjunction with the intercooler housing, and the positioning pins are surrounded by limit blocks 221 to position the intercooler housing;

[0125] With the direction of the placement table 220 moving and feeding as the front, a positioning detection tool 230 for placing positioning nuts, PVC plate sleeves and I-beams is provided in front of the intercooler housing;

[0126] The placement table 220 moves along the length direction of the slide 210, and the positioning nut, the PVC plate sleeve, the I-beam and the intercooler housing are simultaneously transported by the clamping tool 520 arranged on the robot arm.

[0127] First, the intercooler housing is transported to the placement table 220, and the positioning pins and the limit blocks 221 of the placement table 220 cooperate with each other to position the intercooler housing and limit the position of the intercooler housing to prevent the position of the intercooler housing from shifting during transportation;

[0128] Secondly, the nuts, PVC sheet sleeves and I-beams are placed on the positioning and detection tooling 230. The positioning and detection tooling 230 not only defines the positions of the nuts, PVC sheet sleeves and I-beams, but also detects whether the nuts, PVC sheet sleeves and I-beams are in place, thereby ensuring that the robotic arm can clamp and fix the above products.

[0129] Again, after the intercooler housing, nuts, PVC plate sleeves and I-beams are placed in place, the placement table 220 moves linearly along the length direction of the slide 210. After moving to the specified position, the robotic arm drives the clamping tooling 520 to clamp and fix the nuts, PVC plate sleeves, I-beams and intercooler housing in turn, and move them to the next process to complete the assembly.

[0130] From then on, after the intercooler, nuts, PVC plate sleeves and I-beams on the placement table 220 are moved away, the placement table 220 moves to the initial position along the length direction of the slide 210, waiting for personnel to continue to put the above products in, and the cycle is repeated to complete the loading.

[0131] A shell detection sensor 222 located on the placement platform 220 is provided on one side of the intercooler shell. The shell detection sensor 222 is used to confirm whether the intercooler shell is placed in place, thereby ensuring the grasping accuracy of the robot arm.

[0132] The positioning detection tooling 230 includes a storage table 232 arranged on the storage table 220 through a support rod 231, and the storage table 232 is provided with a first contour seat 233, a second contour seat 234 and a third contour seat 235 for placing nuts, PVC plate sleeves and I-beams in sequence to position the nuts, PVC plate sleeves and I-beams.

[0133] It should be noted that the first profiling seat 233 is a shape structure used in conjunction with the nut, the second profiling seat 234 is a shape structure used in conjunction with the PVC plate sleeve, and the third profiling seat 235 is a shape structure used in conjunction with the I-beam. The first profiling seat 233, the second profiling seat 234 and the third profiling seat 235 ensure the stability of the nut, the PVC plate sleeve and the I-beam during movement, and facilitate the robot arm to grasp.

[0134] After the nuts, PVC plate sleeves and I-beams are in place, it is also necessary to check whether the above products are in place. If the above products are not placed in place or are missed, the robotic arm cannot grab them, and it will affect the assembly of the next process. Therefore, when the products are all in place, the placement table 220 will move to the designated position along the length direction of the slide 210 to wait for the robotic arm's clamping tooling 520 to grab them.

[0135] The first contour seat 233 , the second contour seat 234 and the third contour seat 235 are each provided with an in-position detection sensor 236 .

[0136] The in-place detection sensor 236 detects whether the nut, PVC plate sleeve and I-beam are in place to avoid abnormal placement or omission.

[0137] The clamping tool 520 includes a fixed tool 521 connected to the robotic arm and a clamping cylinder arranged on the fixed tool 521. The clamping cylinder is provided with multiple groups and includes a shell clamping cylinder 522, a nut clamping cylinder 523, a PVC clamping cylinder 524 and an I-beam clamping cylinder 525. The nut clamping cylinder 523, the PVC clamping cylinder 524 and the I-beam clamping cylinder 525 are arranged in parallel.

[0138] Among them, the nut clamping cylinder 523, the PVC clamping cylinder 524 and the I-beam clamping cylinder 525 are arranged in parallel, corresponding to the nuts, PVC plate sleeves and I-beams on the positioning and detection tooling 230, so as to facilitate the simultaneous clamping and fixing of these three products and improve efficiency.

[0139] The shell clamping cylinder 522, the nut clamping cylinder 523, the PVC clamping cylinder 524 and the I-beam clamping cylinder 525 are all controlled individually, so that the above products can be clamped and fixed more accurately.

[0140] The housing clamping cylinder 522, the nut clamping cylinder 523, the PVC clamping cylinder 524 and the I-beam clamping cylinder 525 are all provided with clamping claws 526, and the orientation of the clamping claws 526 of the housing clamping cylinder 522 is opposite to that of the nut clamping cylinder 523 and the PVC clamping cylinder 524. The clamping claws 526 of the I-beam clamping cylinder 525 are opposite to each other, so as to avoid interference with the placement table 220 or the slide table 210 during the clamping process of the intercooler housing.

[0141] The intercooler housing and related accessories arrive at the designated location, are clamped and fixed by the clamping tool 520 and transported to the hot plug and press station 300, so that the intercooler housing can be easily assembled with nuts and PVC plate sleeves at the hot plug and press station 300.

[0142] like Figure 1 , Figure 11-Figure 16 As shown, the hot plug and press station 300 includes a press workbench 310 for positioning the intercooler housing, a hot plug tool 320 used in conjunction with the nut at the upper end of the press workbench 310, and an avoidance and abutment tool 330 used in conjunction with a PVC plate sleeve 334 is provided on one side of the press workbench 310;

[0143] The hot plug fixture 320 includes a hot plug 323 and a nut picking assembly, wherein the nut picking assembly adsorbs the nut on the clamping fixture to the hot plug 323 for heating, and inserts the heated nut into the intercooler housing;

[0144] The avoidance and abutment tooling 330 includes an avoidance linear translation module and a vacuum suction head 333 capable of adsorbing a PVC plate sleeve 334 . The avoidance linear translation module assembles the PVC plate sleeve 334 in the intercooler housing through the vacuum suction head 333 .

[0145] It should be noted that the main work of this equipment is to assemble the nut and the PVC plate sleeve 334 in the intercooler housing. The traditional manual assembly method is inefficient and the assembly accuracy is not high. Therefore, in this embodiment, a fully automated processing method is adopted to quickly assemble the nut and the PVC plate sleeve 334 in the intercooler housing.

[0146] First, the nut picking assembly reaches the specified position, and the clamping tool (not shown in the figure) moves the nut to the nut picking assembly. The nut picking assembly grabs the nut and moves it to the original position, and heats the nut through the hot plug 323.

[0147] The clamping tooling positions the intercooler shell on the press-fitting workbench 310. At this time, the avoidance and abutment tooling 330 is in the original position. After the intercooler shell is placed, the avoidance and abutment tooling 330 moves to the specified position. The clamping tooling places the PVC board sleeve 334 on the vacuum suction head 333 of the avoidance and abutment tooling 330, and the PVC board sleeve 334 is adsorbed and fixed by the vacuum suction head 333.

[0148] At this point, the nut has been heated to a certain temperature, and the nut picking assembly assembles the heated nut into the intercooler housing to achieve hot melt assembly.

[0149] When the nut is assembled, the avoidance linear translation module squeezes the PVC plate sleeve 334 into the intercooler housing through the vacuum suction head 333 to complete the assembly of the PVC plate sleeve 334.

[0150] After the above actions are completed, the clamping tool removes the assembled intercooler housing.

[0151] At the same time, the avoidance and abutment tooling 330 moves to the original position.

[0152] The nut picking assembly includes a picking telescopic cylinder 321 and a picking clamp 322 arranged at the telescopic end of the picking telescopic cylinder 321 . The thermal plug 323 is fixed to the picking telescopic cylinder 321 through a connecting plate, and the picking clamp 322 moves relative to the thermal plug 323 .

[0153] Among them, the material picking telescopic cylinder 321 can drive the material picking clamp 322 to move linearly to complete the material picking and assembly of the nut. In addition, the material picking clamp 322 is a structure that can fix the nut by abutting against the inner ring of the nut to complete the fixation of the nut, which will not be described in detail here.

[0154] When the material taking clamp 322 is located at the initial position, the heat plug 323 can heat the nut located at the material taking clamp 322 , and during this process, the position of the heat plug 323 will not change.

[0155] The thermal plug 323 is provided with a thermal plug block 324 which cooperates with the material taking clamp 322 and has an opening 3341 in the middle. The material taking clamp 322 passes through the opening 3341 and moves relative to the thermal plug 323 .

[0156] The material taking clamp 322 and the nut located at the material taking clamp 322 are located in the opening 3341 of the heat plug block 324, and the material taking clamp 322 and the nut are covered by the opening 3341 of the heat plug block 324, so that the heat plug 323 evenly heats the nut, so that the surface of the nut is evenly heated.

[0157] In addition, the heat plug 323 and the heat plug block 324 are components that can heat objects, and are conventional structures in the prior art, and their functions and principles will not be described in detail.

[0158] The inner diameter of the opening 3341 is larger than the outer diameter of the nut, and the inner diameter of the opening 3341 is larger than the outer diameter of the material taking clamp 322 .

[0159] It also includes an oil injection tooling 340 arranged on one side of the hot plug tooling 320, the oil injection tooling 340 includes an oil injection vertical moving cylinder 341, an oil injection horizontal moving cylinder 342 connected to the oil injection vertical moving cylinder 341, and an oil injection nozzle 343 connected to the oil injection horizontal moving cylinder 342, and the oil injection nozzle 343 sprays oil to the nut area of ​​the intercooler housing to be installed.

[0160] The oil spray nozzle 343 is connected to an oil pump, and oil is sprayed into the position of the intercooler housing where the nut is to be installed through the oil pump and the oil spray nozzle 343. The position is lubricated by the oil spray to ensure smoother assembly of the nut.

[0161] The main function of the oil injection vertical movement cylinder 341 and the oil injection horizontal movement cylinder 342 is to move the oil injection nozzle 343 to ensure that the oil injection nozzle 343 can move to a specified position.

[0162] An oil collecting box 344 is provided below the oil spray nozzle 343 to prevent residual oil stains from dripping after oil spraying.

[0163] The avoidance linear translation module includes a avoidance vertical linear translation module 331 and a avoidance lateral linear translation module 332 disposed on the avoidance linear translation module via a column, and the vacuum suction head 333 is disposed on the avoidance lateral linear translation module 332 .

[0164] The function of the avoidance vertical linear translation module 331 is to adjust the position of the entire avoidance abutment tool 330 to avoid interference with the clamping tool when placing the intercooler shell. When the intercooler shell is placed, the avoidance vertical linear translation module 331 is used to make the avoidance abutment tool 330 reach the specified position so that the clamping tool can place the PVC plate sleeve 334 on the vacuum suction head 333 and fix it by suction.

[0165] When the nut assembly is completed after the heating mentioned above, the avoidance lateral linear translation module 332 drives the vacuum suction head 333 to move, so as to squeeze the PVC plate sleeve 334 adsorbed on the vacuum suction head 333 into the intercooler housing.

[0166] The vacuum suction head 333 is connected to the avoidance lateral linear translation module 332 through a buffer component 335. The buffer component 335 buffers the extrusion process of the vacuum suction head 333 to avoid rigid contact between the PVC plate sleeve 334 and the inside of the intercooler shell, thereby avoiding damage to the intercooler shell or the PVC plate sleeve 334 during assembly.

[0167] The press-fitting workbench 310 is provided with a plurality of positioning blocks 311 used in conjunction with the intercooler housing. The positioning blocks 311 define the position of the intercooler housing to prevent the position of the intercooler housing from changing during the assembly process.

[0168] The press-fitting workbench 310 is further provided with a press-fitting cylinder 3121 , the telescopic end of the press-fitting cylinder 3121 is movably connected to a press plate 3122 , and one side of the press plate 3122 is movably connected to the press-fitting cylinder 3121 via a connecting rod 3123 .

[0169] The pressing plate 3122 is movably connected to the telescopic end of the pressing cylinder 3121 and the main body of the pressing cylinder 3121 respectively. By utilizing the principle of movable connection and lever, when the pressing cylinder 3121 is started, the pressing plate 3122 presses and fixes the upper end of the intercooler shell, further ensuring the stability of the intercooler shell.

[0170] After the intercooler housing is assembled with nuts and PVC sheet sleeves at the hot plug and press station 300, the intercooler housing is transported to the I-beam assembly station 400 by the clamping tool 520, and the synchronous clamping tool 540 also transports the I-beam to the I-beam assembly station 400, and the I-beam is fixed at the I-beam transfer station 400.

[0171] like Figure 1 , Figure 17-Figure 24 As shown, the I-beam transfer station 400 includes:

[0172] The housing pressing device 410 is used to fix the intercooler housing;

[0173] It should be noted that the shell pressing device 410 moves to the specified position of the equipment, and the robot (not shown in the figure) simultaneously transports the intercooler shell and the I-beam to the equipment, and places the intercooler shell in the shell pressing device 410 and the I-beam pre-placement position respectively.

[0174] The intercooler shell is pressed and fixed by the shell pressing device 410 to ensure that the position of the intercooler shell does not change during operation.

[0175] The shell pressing device 410 includes a bearing fixture 411 for placing the intercooler shell and a pressing fixture 413 used in conjunction with the intercooler shell and the I-beam. A plurality of telescopic rods 414 are provided between the bearing fixture 411 and the pressing fixture 413. The pressing fixture 413 is used in conjunction with the telescopic rods 414 through a product opening cylinder 415 provided on the bearing fixture 411. The pressing fixture 413 abuts or separates from the upper end of the intercooler shell to fix or release the intercooler shell.

[0176] The I-beam pressing assembly 416 is disposed at the upper end of the pressing fixture 413 to fix the I-beam placed on the intercooler housing;

[0177] A shell linear translation module 412 is provided at the bottom of the supporting tool 411 , and the shell linear translation module 412 drives the shell pressing device 410 to move.

[0178] The shell linear translation module 412 can drive the carrying tooling 411 to translate linearly, and drive the pressing tooling 413 connected to the carrying tooling 411 via a plurality of telescopic rods 414 to move synchronously.

[0179] First, the product expands the cylinder 415 and the telescopic rod 414 to cooperate with each other to drive the pressing tool 413 and the carrying tool 411 to separate. The gap between the two is large, which is convenient for the robot to place the intercooler housing on the carrying tool 411 and directly below the pressing tool 413;

[0180] The shell linear translation module 412 drives the supporting tooling 411 to move to the specified position of the equipment, and the robot places the intercooler shell on the supporting tooling 411; the product expansion cylinder 415 drives the pressing tooling 413 to abut against the upper end surface of the intercooler shell through the telescopic rod 414 to fix the intercooler shell and ensure the stability of the intercooler shell.

[0181] In addition, the supporting fixture 411 and the pressing fixture 413 are shaped structures for use with the intercooler shell. The supporting fixture 411 can support and limit the bottom of the intercooler shell, and the pressing fixture 413 is used in conjunction with the upper end surface of the intercooler shell. By reducing the distance between the pressing fixture 413 and the supporting fixture 411, the intercooler shell placed between the supporting fixture 411 and the pressing fixture 413 can be fixed.

[0182] Next, when the intercooler housing is fixed, the robot places the I-beam into the intercooler housing through the pressing tool 413, and waits to assemble the I-beam and the intercooler housing.

[0183] Before assembly, the I-beam needs to be centered to prevent the position of the I-beam from being offset, which may cause abnormalities during assembly of the I-beam.

[0184] The shell linear translation module 412 drives the carrying tooling 411 to move to the specified position of the equipment again. At this time, the shell pressing device 410 is located below the rivet pressing and I-beam positioning device 420.

[0185] A rivet pressing and I-beam positioning device 420, the rivet pressing and I-beam positioning device 420 comprises a pressing head 421 and a positioning head 422, the positioning head 422 can center the I-beam placed on the intercooler housing, and fix the I-beam to the intercooler housing through the I-beam pressing assembly 416 provided in the housing pressing device 410;

[0186] It should be noted that the rivet pressing and I-beam positioning device 420 is provided with two workstations, one of which is for centering the I-beam through the positioning head 422, and the other is for assembling the rivet through the pressing head 421 to fix the I-beam to the intercooler shell; the pressing head 421 and the positioning head 422 are controlled separately, and the two do not work at the same time, and when it is necessary to center the I-beam, the shell pressing device 410 moves to the bottom of the positioning head 422 so that the positioning head 422 completes the centering of the I-beam; when it is necessary to assemble the rivet, the shell pressing device 410 moves again to the bottom of the pressing head 421 so that the pressing head 421 completes the assembly of the rivet.

[0187] The rivet pressing and I-beam positioning device 420 also includes a rivet pressing cylinder 4213, which is arranged inside the device through a support assembly, and the pressing head 421 is connected to the telescopic end of the rivet pressing cylinder 4213 through a horizontal plate 4214 used in conjunction with the support assembly, and can move vertically up and down along the height direction of the support assembly to align the rivet assembly between the intercooler shell and the I-beam in the shell pressing device 410 below;

[0188] A limiting rod 423 is further provided at the bottom of the transverse plate 4214 , and the movement of the transverse plate 4214 is limited by the limiting rod 423 .

[0189] The supporting assembly is a mechanism capable of supporting the rivet pressing cylinder 4213. The supporting assembly in this embodiment is composed of four sliding rods 4211 and an upper panel 4212 arranged at the ends of the four sliding rods 4211. The rivet pressing cylinder 4213 is fixed to the upper panel 4212. In addition, the four sliding rods 4211 respectively pass through the four sides of the cross plate 4214, so that the cross plate 4214 can move vertically up and down along the height direction of the sliding rods 4211. The telescopic end of the rivet pressing cylinder 4213 passes through the upper panel 4212 and is connected to the upper end of the cross plate 4214. The pressing head 421 is arranged at the lower end of the cross plate 4214. The pressing head 421 is driven by the rivet pressing cylinder 4213 to move vertically up and down to complete the assembly of the rivet.

[0190] The positioning head 422 is positioned on the support assembly through a rivet to position the pressing cylinder 4221 .

[0191] The rivet positioning pressing cylinder 4221 is connected to the upper panel 4212, and the positioning head 422 is located at the telescopic end of the rivet pressing cylinder 4213. The rivet pressing cylinder 4213 directly drives the positioning head 422 to center the I-beam on the intercooler shell.

[0192] After the I-beam on the intercooler housing is centered, the position of the I-beam is fixed by the I-beam pressing assembly 416 to prevent the position of the I-beam from shifting and ensure the accuracy of the subsequent rivet assembly.

[0193] The I-beam pressing assembly 416 includes an I-beam pressing cylinder 4161 and a pressing rod 4162 connected to the telescopic end of the I-beam pressing cylinder 4161 , and the end of the pressing rod 4162 is movably connected to the pressing tool 413 via a bracket 4163 .

[0194] First, the I-beam can pass through the pressing tool 413 and be placed on the upper end of the intercooler shell. It can be seen that the upper end of the pressing tool 413 is provided with an opening for use with the I-beam. The opening not only facilitates the placement of the I-beam into the intercooler shell, but also can preliminarily limit the position of the I-beam so that the positioning head 422 can quickly center the I-beam.

[0195] The I-beam clamping cylinder 4161 is fixed to the end of the pressing tool 413. The I-beam clamping cylinder 4161 drives the pressing rod 4162 to move. Since the pressing rod 4162 is movably connected to the telescopic end of the I-beam clamping cylinder 4161 and the bracket 4163 respectively, when the I-beam clamping cylinder 4161 is started, the head end of the pressing rod 4162 abuts against the surface of the I-beam to fix the I-beam.

[0196] When the I-beam is fixed, the rivet positioning pressing cylinder 4221 drives the positioning head 422 to return to the initial position.

[0197] At the same time, the shell linear translation module 412 drives the entire shell pressing device 410 to move to the bottom of the lower pressing head 421 again to complete the rivet assembly process.

[0198] The rivet material connection and guide device 430 comprises a material connection linear translation module and a material connection platform 433 provided on the material connection linear translation module. The material connection platform 433 is provided with a guide sleeve assembly 434 for placing rivets. The material connection linear translation module drives the material connection platform 433 to abut against the upper end of the shell pressing device 410.

[0199] The pressing head 421 passes through the guide sleeve assembly 434 to squeeze out the rivet in the guide sleeve assembly 434 to fix the intercooler housing to the I-beam.

[0200] It should be noted that, the material receiving linear translation module includes a material receiving transverse linear translation module 431 and a material receiving vertical linear translation module 432 arranged on the material receiving transverse linear translation module 431, and the material receiving platform 433 is arranged on the material receiving vertical linear translation module 432; in addition, the linear translation mentioned above is a structure that can realize the translation of components, and the design of linear translation modules in the prior art is quite mature, therefore, the relevant principles and structures of the linear translation module will not be described in detail here.

[0201] When the shell pressing device 410 moves to the bottom of the pressing head 421, the bottom of the material receiving platform 433 is abutted against the upper end of the pressing tool 413 through the cooperation of the material receiving lateral linear translation module 431 and the material receiving vertical linear translation module 432. At this time, the guide sleeve assembly 434 located on the material receiving platform 433 is located directly above the I-beam, so that the rivet in the guide sleeve assembly 434 can be squeezed out through the pressing head 421 to complete the assembly of the I-beam and the intercooler shell.

[0202] The guide sleeve assembly 434 includes a guide tube 4341 of a hollow structure, and two arc-shaped guide plates 4342 are symmetrically hinged on the side wall of the guide tube 4341, and an O-ring is provided on the outer wall of the arc-shaped guide plate 4342 to cover the guide plate and the guide tube 4341;

[0203] There are two states between the arc-shaped guide plate 4342 and the guide tube 4341:

[0204] The two arc-shaped guide plates 4342 abut against each other and form an inverted cone-shaped structure to limit the rivet in the guide tube 4341;

[0205] When the two arc-shaped guide plates 4342 are relatively separated, the rivet can be disengaged from the guide tube 4341 .

[0206] It should be noted that, since the O-ring (not shown in the figure) covers the arc guide plate 4342 and the guide tube 4341, the arc guide plate 4342 is fitted to the guide tube 4341 by utilizing the elasticity of the O-ring. At this time, the two arc guide plates 4342 abut against each other to form an inverted cone-shaped structure to ensure that the rivet in the guide tube 4341 will not fall off; when the lower pressure head 421 passes through the guide tube 4341 and applies a downward force to the rivet, the bottom of the rivet abuts against the inner walls of the two arc guide plates 4342 to spread the two arc guide plates 4342 apart, making it easier for the rivet to fall off relative to the guide tube 4341 and pass through the I-beam into the intercooler housing to complete the fixation of the I-beam and the intercooler housing.

[0207] The coordinated use of the arc-shaped guide plate 4342 and the O-ring not only ensures that the rivets stored in the guide tube 4341 will not fall off, but also guides the assembly of the rivets, thereby ensuring the assembly progress of the rivets.

[0208] The guide sleeve assembly 434 is provided in multiple groups, and the multiple groups of guide sleeve assemblies 434 are used in conjunction with the I-beam to ensure that the I-beam is fixed to the intercooler housing at one time.

[0209] In addition, the action process of the pressing head 421 has been described in detail above. When the material receiving platform 433 abuts against the pressing tooling 413, the material receiving platform 433 is also located directly below the pressing head 421. The pressing head 421 moves vertically downward, passing through the material receiving platform 433 and the guide tube 4341 in turn to assemble the rivet in the guide tube 4341.
