[0002] Gear reducers are generally used in low-speed, high-torque transmission equipment. They convert the high-speed power of a motor into low-speed power output through gear transmission within the reduction mechanism. Currently, gear reducers and motors are usually connected by flanges. One end of this flange has a stop and mounting hole for connecting the motor, and the other end has a stop and mounting hole for connecting the gear reducer housing. The flange has a central stepped hole in the middle, with bearing mounting holes at both ends. A boss is provided between the two bearing mounting holes.

[0014] As a preferred embodiment, a precision machining process for a reducer flange includes the following steps: Step 1, conveying process: Place the flange end face flat on the conveyor belt. The protrusions on the conveyor belt are located in the mounting holes of the flange to position the flange. The conveyor belt then transports the flange to each workstation. Step two, the trenching process: After the conveyor belt carrying the flange moves to the position of the trenching mechanism, it stops. The fifth hydraulic component drives the second lifting plate to lower the hollow drill rod. The hollow drill rod descends into the installation hole and begins to rotate. At the same time, the sixth hydraulic component drives the wedge block to descend. The wedge block drives the two sets of second drill bits to slowly move outward of the hollow drill rod. The second drill bits open an embedding groove on the inner wall of the installation hole. Then, the sixth hydraulic component drives the wedge block to rise, and the second drill bits retract into the hollow drill rod. The fifth hydraulic component drives the hollow drill rod to rise and reset. The second stepper motor drives the second lifting plate to rotate the hollow drill rod one-eighth of a revolution. The hollow drill rod descends again and opens an air inlet groove on the flange end face. After the hollow drill rod rises and resets, it descends slowly again. At the same time, the second stepper motor drives the hollow drill rod to continue to rotate. The first drill bit at the lower end of the hollow drill rod opens a receiving groove on the flange end face. Step 3, Embedding process: After the conveyor belt moves the flange to the position of the embedding mechanism, it stops. The cleaning component cleans the embedding groove on the inner wall of the mounting hole, the receiving groove for placing the air pipe on the flange end face, and the inflation groove in turn. The gluing component applies glue to the inner wall of the embedding groove and the inner wall of the receiving groove. The grooving component drives the hollow rubber ring to expand outward to adhere to the embedding groove and guides the air pipe into the receiving groove. At the same time, it pulls the limiting block at the end of the air pipe into the inflation groove. Step 4, pressing process: After the conveyor belt carries the flange to the position of the embedding mechanism, it stops. The inflation units in the material conveying channel enter the discharge port in sequence under the elastic push of the push plate. The glue roller applies glue to the lower port of the piston tube that is about to enter the discharge port. The seventh hydraulic component drives the third lifting plate to descend to the flange end face. The eighth hydraulic component drives the pressure plate to press and stick the inflation units in the discharge port onto the inflation groove on the flange end face. Step 5, sealing process: The conveyor belt moves the flange to the sealing mechanism and then stops. The ninth hydraulic component drives the fourth hanging plate to descend with the blocking column. The blocking column descends into the mounting hole on the flange end face. The automatic glue injection head injects a certain amount of glue into the receiving groove of the flange. After the glue solidifies, it seals the receiving groove.

[0015] The beneficial effects of this invention are: (1) In this invention, the combination of the grooving mechanism and the embedding mechanism can, on the one hand, embed a hollow rubber ring into the inner wall of the mounting hole of the flange. After the flange is assembled onto the reducer through the mounting hole by fastening bolts, the hollow rubber ring is inflated and expanded to wrap the fastening bolts, sealing the gap between the fastening bolts and the mounting hole, preventing dust or water from seeping into the reducer through the gap of the mounting hole, and protecting the internal components of the reducer. On the other hand, embedding grooves, receiving grooves and inflation grooves can be automatically opened on the flange, with high processing accuracy, which makes it convenient for the hollow rubber ring to be accurately assembled into the designated position of the flange. (2) In this invention, the groove assembly can, on the one hand, support the hollow rubber ring to adhere to the inside of the groove, automatically assemble the hollow rubber ring, prevent the hollow rubber ring from falling out of the groove and interfering with the screwing operation of the fastening bolt in the mounting hole, prevent the hollow rubber ring from being squeezed and broken by the fastening bolt after deflating, and ensure that the hollow rubber ring can be used multiple times; on the other hand, it can guide the supporting air tube to enter the receiving groove in an arc and pull the limiting block at the end of the air tube into the inflation groove. By pressing down the limiting block, the air tube can be driven to tighten and adhere to the bottom of the receiving groove, preventing the air tube from falling out of the receiving groove.

[0016] In summary, this equipment has the advantages of high automation and good processing accuracy, and is especially suitable for the field of reducer flange technology. Attached Figure Description

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1 like Figures 1-12As shown, a gear reducer flange precision machining equipment includes a flange 9 comprising a hollow rubber ring 92 embedded in the inner wall of a mounting hole 91, an air pipe 93 connected to the hollow rubber ring 92, an inflation groove 94 formed on the end face of the flange 9, a limiting block 95 disposed at one end of the air pipe 93 and located inside the inflation groove 94, an inflation port disposed on the limiting block 95 and connected to the end of the air pipe 93, and an inflation unit 96 disposed on the inflation groove 94. The inflation unit 96 includes a piston tube 961 disposed on the inflation groove 94, a piston plate 962 slidably disposed inside the piston tube 961, and a threaded rod 963 threadedly disposed at the end of the piston tube 961 and used to drive the piston plate 962 to move. After the flange 9 is assembled onto the reducer through the mounting hole 91 by the fastening bolts, the air filling unit 96 inflates the hollow rubber ring 92 through the air pipe 93. The hollow rubber ring 92 expands to wrap around the fastening bolts, sealing the gap between the fastening bolts and the mounting hole 91, and preventing dust or water from seeping into the reducer through the gap of the mounting hole 91. The equipment includes a conveying mechanism 2, a grooving mechanism 3, an embedding mechanism 4, a pressing mechanism 5, and a sealing mechanism 6 arranged sequentially on the frame 1. The embedding mechanism 4 is used to assemble the hollow rubber ring 92, the air pipe 93, and the limiting block 95 onto the flange 9. It includes a grooving assembly 41, an adhesive application assembly 42, and a grooving assembly 43. The mounting assembly 43 includes an inner liner tube 431, a support plate 432 which is set at the lower end of the inner liner tube 431 by two sets of hangers and is adapted to the inner wall of the mounting hole 91, and an outer support unit 433 which is rotatably set inside the inner liner tube 431 and is used to drive the hollow rubber ring 92 to expand outward and embed into the inner wall of the mounting hole 91. Several sets of hollow rubber rings 92 are inelastically sleeved on the inner liner tube 431 from bottom to top. The cleaning component 41 cleans the inner wall of the mounting hole 91, the receiving groove 98 on the flange end face where the air pipe 93 is placed, and the inflation groove 94 in sequence. The gluing component 42 applies glue to the inner wall of the mounting groove 97 and the inner wall of the receiving groove 98. The mounting component 43 drives the hollow rubber ring 92 to expand outward to adhere to the mounting groove 97 and guides the air pipe 93 into the receiving groove 98. At the same time, it pulls the limiting block 95 at the end of the air pipe 93 into the inflation groove 94.

[0033] It should be noted that the deflated hollow rubber ring 92 is completely hidden in the embedding groove 97 on the inner wall of the mounting hole 91, and will not interfere with the screwing of the fastening bolt in the mounting hole 91; the inflated hollow rubber ring 92 expands in volume to fill the entire embedding groove 97, and part of the hollow rubber ring 92 expands out of the embedding groove 97, tightly wrapping the outer wall of the fastening bolt, thus achieving the effect of sealing the mounting hole 91.

[0034] In this embodiment, the drilling mechanism 3 and the embedding mechanism 4 work together to achieve the following: First, a hollow rubber ring 92 can be embedded in the inner wall of the mounting hole 91 of the flange 9. After the flange 9 is assembled onto the reducer through the mounting hole 91 by fastening bolts, the hollow rubber ring 92 inflates to wrap around the fastening bolts, sealing the gap between the fastening bolts and the mounting hole 91, preventing dust or water from seeping into the reducer through the gap in the mounting hole 91, and protecting the internal components of the reducer. Second, the embedding groove 97, the receiving groove 98, and the inflation groove 94 can be automatically opened on the flange 9, with high processing precision, making it convenient for the hollow rubber ring 92 to be accurately assembled into the designated position of the flange 9.

[0035] In detail, firstly, the end face of flange 9 is placed flat on conveyor belt 21. The protrusions 22 on conveyor belt 21 are located in the mounting holes 91 of flange 9 to position flange 9. Conveyor belt 21 then transports flange 9 to various workstations. Next, conveyor belt 21, carrying flange 9, moves to the position of drilling mechanism 3 and stops. The fifth hydraulic component 31 drives the second lifting plate 33 to descend with hollow drill rod 34. Hollow drill rod 34 descends into the mounting hole 91 and begins to rotate. Simultaneously, the sixth hydraulic component 37 drives wedge block 38 to descend. Wedge block 38 drives two sets of second drill bits 39 to slowly move outward from the hollow drill rod 34. The second drill bits 39 are in the mounting hole... An embedding groove 97 is opened on the inner wall of flange 91. Then, the sixth hydraulic component 37 drives the wedge block 38 to rise, and the second drill bit 39 retracts into the hollow drill rod 34. The fifth hydraulic component 31 drives the hollow drill rod 34 to rise and reset. The second stepper motor 32 drives the second lifting plate 33 to rotate the hollow drill rod 34 one-eighth of a revolution. The hollow drill rod 34 descends again, and an air inlet groove 94 is opened on the end face of flange 9. After the hollow drill rod 34 rises and resets, it descends slowly again. At the same time, the second stepper motor 32 drives the hollow drill rod 34 to continue to rotate. The first drill bit 36 ​​at the lower end of the hollow drill rod 34 opens a receiving groove 98 on the end face of flange 9. Then, the conveyor belt 21 carries the flange 9 to the embedding groove. After the mechanism 4 is positioned, it stops operating. The cleaning assembly 41 cleans the inner wall of the mounting hole 91, the receiving groove 97 where the air pipe 93 is placed, and the inflation groove 94. The gluing assembly 42 applies glue to the inner wall of the mounting hole 97 and the receiving groove 98. The mounting assembly 43 drives the hollow rubber ring 92 to expand outward to adhere to the mounting hole 97 and guides the air pipe 93 into the receiving groove 98. At the same time, it pulls the limiting block 95 at the end of the air pipe 93 into the inflation groove 94. Then, the conveyor belt 21 carries the flange 9 to the position of the mounting mechanism 4 and stops operating. The inflation unit 96 in the material conveying channel 54 is pushed elastically by the push plate 55. The piston tube 961, which is about to enter the discharge port 56, is coated with glue by the glue-applying roller 57. The seventh hydraulic component 51 drives the third lifting plate 53 to descend to the end face of the flange 9. The eighth hydraulic component 58 drives the pressure plate 59 to press the inflation unit 96 in the discharge port 56 onto the inflation groove 94 on the end face of the flange 9. Then, the conveyor belt 21 moves the flange 9 to the position of the glue sealing mechanism 6 and stops. The ninth hydraulic component 61 drives the fourth lifting plate 62 to descend with the blocking column 63. The blocking column 63 descends into the mounting hole 91 on the end face of the flange 9. The automatic glue injection head 64 injects a certain amount of glue into the receiving groove 98 of the flange 9. After the glue solidifies, it seals the receiving groove 98.

[0036] Furthermore, such as Figure 4 As shown, the conveying mechanism 2 is used to carry the flange 9. It includes a conveyor belt 21 rotatably mounted on the frame 1 and a protrusion 22 mounted on the conveyor belt 21 and adapted to the mounting hole 91 of the flange 9. The protrusion 22 is used to position the flange 9.

[0037] It should be noted that the protrusion 22 is relatively short and serves to position the mounting hole 91 of the flange 9, without interfering with the opening of the embedding groove 97 on the inner wall of the mounting hole 91.

[0038] In this embodiment, the conveying mechanism 2 can carry the flange 9 to the workstations of the drilling mechanism 3, the embedding mechanism 4, the pressing mechanism 5, and the sealing mechanism 6, and position the flange 9 to prevent it from shifting during processing, thus ensuring processing accuracy.

[0039] In detail, the flange 9 is placed flat on the conveyor belt 21, and the protrusions 22 on the conveyor belt 21 are located in the mounting holes 91 of the flange 9 to position the flange 9. The conveyor belt 21 then transports the flange 9 to each workstation.

[0040] Furthermore, such as Figures 5-6 As shown, the trenching mechanism 3 includes: The fifth hydraulic component 31 is mounted on the frame 1, and the output end of the fifth hydraulic component 31 is provided with a second stepper motor 32; The second hanging plate 33 is disposed on the output end of the second stepper motor 32; Hollow drill rod 34, four sets of hollow drill rods 34 are rotatably mounted on the second hanging plate 33. The hollow drill rod 34 is used to open an air inlet 94 on the end face of the flange 9. The second hanging plate 33 is equipped with a fourth motor 35, which drives the hollow drill rod 34 to rotate through the transmission of belt and pulley. The first drill bit 36 ​​is disposed at the lower end of the hollow drill rod 34 and is used to open a receiving groove 98 on the end face of the flange 9. The sixth hydraulic component 37 is disposed inside the hollow drill rod 34, and a wedge block 38 is provided at the output end of the sixth hydraulic component 37; The second drill bit 39, two sets of the second drill bit 39 are symmetrical and limited to slide on the two inclined surfaces of the wedge block 38, one end of the second drill bit 39 extends to the outside of the hollow drill rod 34, and is used to open an embedding groove 97 in the inner wall of the mounting hole 91.

[0041] In this embodiment, the drilling mechanism 3 can be used to open an embedding groove 97 on the inner wall of the mounting hole 91, and to open a receiving groove 98 and an air filling groove 94 on the end face of the flange 9. The automation is high and the drilling accuracy is good.

[0042] In detail, after the conveyor belt 21 carrying the flange 9 moves to the position of the drilling mechanism 3, it stops. The fifth hydraulic component 31 drives the second lifting plate 33 to descend with the hollow drill rod 34. The hollow drill rod 34 descends into the mounting hole 91. The fourth motor 35 drives the hollow drill rod 34 to start rotating through the transmission of belts and pulleys. At the same time, the sixth hydraulic component 37 drives the wedge block 38 to descend. The wedge block 38 drives the two sets of second drill bits 39 to slowly move out of the hollow drill rod 34. The second drill bits 39 cut an embedding groove 97 along the inner wall of the mounting hole 91. Then, the sixth hydraulic component 37 drives the wedge block 38 to rise and reset. The second drill bits 39 retract into the hollow drill rod 34. The fifth hydraulic component 31 drives the hollow drill rod 34 to rise and reset. The second stepper motor 32 drives the second lifting plate 33 to descend with the hollow drill rod 34. Plate 33 rotates the hollow drill rod 34 by 45 degrees, positioning the hollow drill rod 34 above the inflation groove 94 to be opened on the end face of flange 9. The fifth hydraulic component 31 drives the hollow drill rod 34 to descend again, and the fourth motor 35 drives the hollow drill rod 34 to rotate via belt and pulley transmission. The hollow drill rod 34 opens the inflation groove 94 on the end face of flange 9. Then, the fifth hydraulic component 31 drives the hollow drill rod 34 to rise and reset, and then slowly descends. At the same time, the second stepper motor 32 drives the hollow drill rod 34 to continue to revolve, and the fourth motor 35 drives the hollow drill rod 34 to rotate. The first drill bit 36 ​​at the lower end of the hollow drill rod 34 opens a receiving groove 98 on the end face of flange 9, so that the receiving groove 98 connects the adjacent inflation groove 94 and the embedding groove 97 of the mounting hole 91.

[0043] Furthermore, such as Figure 7 As shown, the cleaning assembly 41 includes: A first hydraulic component 411 is mounted on the frame 1, and a first stepper motor 412 is mounted at the output end of the first hydraulic component 411. The first hanging plate 413 is disposed on the output end of the first stepper motor 412; A cleaning pipe 414 is vertically rotatably mounted on the first hanging plate 413. An air pump 415 is installed at the upper end of the cleaning pipe 414. A first motor 416 is installed on the first hanging plate 413, which drives the cleaning pipe 414 to rotate through a belt and pulley transmission method. The first air nozzle 417 is disposed at the lower end of the cleaning pipe 414 and is used to clean the waste inside the receiving groove 98 and the air filling groove 94. The second air nozzle 418 is located on the outer wall of the lower end of the cleaning pipe 414 and is used to clean the waste inside the embedded groove 97.

[0044] In this embodiment, the cleaning component 41 can automatically clean the embedded groove 97 on the inner wall of the mounting hole 91, the receiving groove 98 on the end face of the flange 9, and the inflation groove 94, so as to avoid the waste from affecting the assembly of the hollow rubber ring 92 and the air pipe 93.

[0045] In detail, after the conveyor belt 21 carrying the flange 9 moves to the position of the embedding mechanism 4, it stops. The first hydraulic component 411 drives the first lifting plate 413 to descend with the cleaning pipe 414 to the designated position inside the mounting hole 91, so that the second air nozzle 418 is directly facing the embedding groove 97 on the inner wall of the mounting hole 91. The air pump 415 supplies air to the second air nozzle 418. At the same time, the first motor 416 drives the cleaning pipe 414 to rotate through the transmission of belt and pulley. The second air nozzle 418 cleans the debris inside the embedding groove 97. Then, the first hydraulic component 411 drives the first lifting plate 413 to rise and reset with the cleaning pipe 414. The first stepper motor 412 drives the first lifting plate 413 to rotate 45 degrees with the cleaning pipe 414, so that the cleaning pipe 414 stops directly above the inflation groove 94. During the 45-degree revolution, the air pump 415 supplies air to the first air nozzle 417, which cleans the debris inside the receiving groove 98. When the cleaning pipe 414 stops directly above the inflation groove 94, the first air nozzle 417 cleans the debris from the inflation groove 94. The first stepper motor 412 drives the first hanging plate 413 to carry the cleaning pipe 414 and rotate it another 45 degrees, so that the cleaning pipe 414 stops directly above the next mounting hole 91. During the 45-degree revolution, the first air nozzle 417 cleans the debris inside the receiving groove 98 again. The cleaning pipe 414 descends, and the second air nozzle 418 cleans the debris inside the embedding groove 97. This process continues until the cleaning pipe 414 completes one revolution, thus completing the cleaning of the embedding groove 97, the receiving groove 98, and the inflation groove 94 in sequence.

[0046] Furthermore, such as Figure 7 As shown, the adhesive application assembly 42 includes: A hose 421 is vertically rotatably mounted on a first hanging plate 413. A second motor 422 is mounted on the first hanging plate 413, which is used to drive the hose 421 to rotate. The first adhesive head 423 is disposed on the outer wall of the lower end of the adhesive tube 421 and is used to apply adhesive to the inside of the receiving groove 98. The second adhesive head 424 is disposed at the lower end of the adhesive tube 421 and is used to apply adhesive to the inside of the embedding groove 97.

[0047] It should be noted that the first rubber head 423 is made of soft sponge material. When the lower end of the rubber tube 421 descends into the mounting hole 91, the first rubber head 423 can deform and bend, which will not hinder the rubber tube 421 from descending into the mounting hole 91. When the first rubber head 423 descends to the position of the embedding groove 97 on the inner wall of the mounting hole 91, the first rubber head 423 returns to its original shape to abut against the inner wall of the embedding groove 97, so that the adhesive can be applied smoothly to the inner wall of the embedding groove 97.

[0048] In this embodiment, the adhesive application component 42 can apply adhesive to the inner walls of the embedding groove 97 and the receiving groove 98, which facilitates the bonding and fixing of the hollow rubber ring 92 in the embedding groove 97 and the bonding and fixing of the air pipe 93 in the receiving groove 98, thus preventing the hollow rubber ring 92 from detaching from the embedding groove 97 and interfering with the screwing operation of the fastening bolt in the mounting hole 91.

[0049] In detail, during the process of the cleaning tube 414 of the cleaning assembly 41 revolving once, the rubber tube 421 simultaneously descends to the designated position inside the mounting hole 91, so that the first rubber head 423, which has been deformed and restored to its original shape, abuts against the inner wall of the embedding groove 97. The second motor 422 drives the rubber tube 421 to rotate, and the first rubber head 423 revolves inside the embedding groove 97, applying glue to the inner wall of the embedding groove 97. Then, the rubber tube 421 rises and resets, and the first hanging plate 413 carries the rubber tube 421 to revolve. The rubber tube 421 descends to the receiving groove 98, and the first rubber head 423 applies glue to the inner wall of the receiving groove 98. The first hanging plate 413 carries the rubber tube 421 to revolve once, completing the glue application work of the embedding groove 97 and the receiving groove 98.

[0050] Furthermore, such as Figures 7-9 As shown, the slotting assembly 43 further includes: Arc-shaped support plate 434, two sets of arc-shaped support plates 434 are symmetrically arranged on the first hanging plate 413 and located on both sides of the inner liner tube 431 respectively, and are used to support the air pipe 93 in an arc distribution directly above the receiving groove 98; The two sets of the descent channels 435 are symmetrically arranged on the first hanging plate 413 and located on one side of the arc-shaped support plate 434, and are used to pull the limiting block 95 to drive the air tube 93 in an arc state. Two sets of triangular blocks 436 are symmetrically and elastically slidably disposed inside the descent channel 435, and are used to support the connection between the air tube 93 and the limiting block 95. The second hydraulic component 437 is mounted on the first hanging plate 413, and a connecting block is provided at the output end of the second hydraulic component 437. The third hydraulic component 438 is disposed on the connecting block. The output end of the third hydraulic component 438 is provided with a lever 439, which is used to extend into the air inlet of the limiting block 95 to drive the air pipe 93 down and disengage from the triangular stop block 436. It should be noted that when it is necessary to add a new hollow rubber ring 92 to the inner liner tube 431, the hollow rubber ring 92 is manually expanded outward from the lower end of the inner liner tube 431. The hollow rubber ring 92 is then placed over the support plate 432 and then over the upper end of the inner liner tube 431. The air pipes 93 on both sides of the hollow rubber ring 92 are manually placed on the arc-shaped support plate 434, and the limiting block 95 is locked on the outside of the falling channel 435. New hollow rubber rings 92 are added sequentially from the upper end of the inner liner tube 431 downward. The external support unit 433 includes: The upright pole 4331 is rotatably mounted on the first hanging plate 413. The upper end of the inner lining tube 431 is mounted on the first hanging plate 413. The upright pole 4331 is located on the axis of the inner lining tube 431. A third motor 4332 is mounted on the first hanging plate 413. The third motor 4332 is used to drive the upright pole 4331 to rotate. The upright plate 4333 is disposed at the lower end of the upright rod 4331. The two sides of the upright plate 4333 are respectively slidably fitted with outer abutment plates 4334. The outer abutment plates 4334 are located at the gap between the lower end of the inner liner tube 431 and the support plate 432. One end of the outer abutment plate 4334 is rotatably provided with abutment wheel 4335. The fourth hydraulic component 4336, the two sets of the fourth hydraulic components 4336 are respectively disposed on the two sides of the vertical plate 4333, and are used to drive the two sets of outer abutment plates 4334 to move in opposite directions respectively.

[0051] In this embodiment, the slotting assembly 43 serves two purposes: firstly, it can externally support the hollow rubber ring 92 and bond it to the inside of the embedding groove 97, automatically assembling the hollow rubber ring 92 and preventing it from detaching from the embedding groove 97. This also prevents the fastening bolt from interfering with the screwing operation in the mounting hole 91, thus preventing the hollow rubber ring 92 from being crushed by the fastening bolt after deflating and ensuring that the hollow rubber ring 92 can be used multiple times. Secondly, it can guide the supporting air tube 93 into the receiving groove 98 in an arc shape and pull the limiting block 95 at the end of the air tube 93 into the inflation groove 94. By pressing down the limiting block 95, the air tube 93 can be tightened and bonded to the bottom of the receiving groove 98, preventing the air tube 93 from detaching from the receiving groove 98.

[0052] In detail, the first stepper motor 412 drives the first lifting plate 413 to intermittently rotate the inner liner tube 431 by 90 degrees, so that the inner liner tube 431 stops directly above the mounting hole 91 each time. The first hydraulic component 411 drives the first lifting plate 413 to descend the inner liner tube 431 to the designated position inside the mounting hole 91. The support plate 432 descends to the position flush with the embedded groove 97, and the arc-shaped support plate 434 descends to the receiving groove 98 of the flange 9. The third hydraulic component 438 drives the lifting rod 439 to extend into the air port of the limiting block 95 at the lowest position on the inner liner tube 431. The second hydraulic component 437 drives the lifting rod 439 to descend. The lifting rod 439 drives the limiting block 95 to descend along the arc-shaped support plate 434 with the air pipe 93. The two sets of limiting blocks 95 drive the hollow rubber ring 92 at the lowest position on the inner liner tube 431 to descend through the air pipe 93, so that the limiting... Block 95 descends into the inflation groove 94, air pipe 93 descends to the bottom of receiving groove 98, and hollow rubber ring 92 descends onto support plate 432. Then, the fourth hydraulic component 4336 of the outer support unit 433 drives the two sets of outer abutment plates 4334 to move in opposite directions. One end of the outer abutment plate 4334 drives the hollow rubber ring 92 to expand to both sides to the inner wall of the embedded groove 97. The third motor 4332 drives the upright 4331 to rotate nearly half a turn, so that the upright 4331 carries the two sets of outer abutment plates 4334 to revolve. The abutment wheel 4335 at one end of the outer abutment plate 4334 presses the hollow rubber ring 92 onto the inner wall of the embedded groove 97 in segments. The third hydraulic component 438 drives the lifting rod 439 to disengage from the inflation port of the limiting block 95. The limiting block 95 is stuck in the inflation groove 94. The first hydraulic component 411 drives the first hanging plate 413 to rise and reset with the inner liner tube 431, ready for the next use.

[0053] Furthermore, such as Figures 10-11 As shown, the pressing mechanism 5 is used to assemble the inflation unit 96 onto the inflation groove 94 on the end face of the flange 9, and includes: The seventh hydraulic component 51 is mounted on the frame 1.

The eighth hydraulic component 58 is disposed on the transition plate 52. The output end of the eighth hydraulic component 58 is provided with a pressure plate 59, which is used to press the inflation unit 96 in the discharge port 56 down to the inflation groove 94 on the end face of the flange 9.

[0054] In this embodiment, the pressure fitting mechanism 5 can automatically bond the inflation unit 96 to the inflation groove 94, which is highly automated and securely installed.

[0055] In detail, after the conveyor belt 21 carries the flange 9 to the position of the embedding mechanism 4, it stops. The inflation unit 96 in the material conveying channel 54 enters the discharge port 56 in sequence under the elastic push of the push plate 55.

[0057] In this embodiment, the sealing mechanism 6 can seal the air tube 93 inside the receiving groove 98, preventing the air tube 93 from being exposed to the environment and damaged.
