[0075] The present invention provides a hydraulic clutch assembly line, such as Figure 11 and Figure 12 As shown, it is used to assemble the hydraulic clutch assembly 1.

[0076] Among them, such as Figure 3 、 Figure 4 、 Figure 11 and Figure 12 As shown, the hydraulic clutch assembly 1 includes a cylinder body assembly 11 , a shift shaft assembly 12 , a pressure plate assembly 13 , a ring gear 14 , a first fastener 15 and a second fastener 16 .

[0077] Among them, such as Figure 3 、 Figure 4 、 Figure 11 and Figure 12 As shown, the cylinder assembly 11 includes a first bearing 115 , a cylinder body 116 and a piston assembly.

[0078] Specifically, if Figure 3 、 Figure 4 、 Figure 11 and Figure 12 As shown, the first end of the cylinder body 116 in the axial direction is provided with a first bearing connection portion 1163 and a first limit surface, and the first bearing 115 is fixedly sleeved on the outer periphery of the first bearing connection portion 1163 and abuts against the first limit surface in the axial direction. The second end of the cylinder body 116 in the axial direction is provided with an annular oil groove, and a first mounting portion 1164 is formed in the annular oil groove. The piston assembly is arranged in the annular oil groove and a hydraulic oil chamber 117 is formed between the piston assembly and the inner wall of the annular oil groove. The first bearing connection portion 1163 is provided with a first center oil hole 11631, one end of the first center oil hole 11631 is connected to the oil groove, and the other end of the first center oil hole 11631 is used to connect to the hydraulic oil source. This allows hydraulic oil to be transported into the hydraulic oil chamber 117.

[0079] Specifically, if Figure 12 As shown, the piston assembly includes a piston 112, which is slidably disposed within an annular oil groove and forms a hydraulic oil chamber 117 between piston 112 and the inner wall of the annular oil groove. When hydraulic oil is supplied to hydraulic oil chamber 117, the hydraulic oil in hydraulic oil chamber 117 pushes piston 112 to slide axially relative to cylinder body 116. It will be appreciated that piston 112 is an annular piston, and the hydraulic oil chamber formed is an annular hydraulic oil chamber.

[0080] Specifically, if Figure 4 and Figure 12 As shown, the piston assembly further includes a sealing ring 118, which is embedded in both the outer and inner circumferential walls of the piston 112. The sealing ring 118 embedded in the outer circumferential wall of the piston 112 is used to seal the gap between the piston 112 and the inner circumferential wall of the annular oil groove, and the sealing ring 118 embedded in the inner circumferential wall of the piston 112 is used to seal the gap between the piston 112 and the first mounting portion 1164. This prevents the hydraulic oil in the hydraulic oil chamber 117 from leaking through the gap between the outer circumferential wall of the piston 112 and the inner circumferential wall of the annular oil groove, and prevents the hydraulic oil in the hydraulic oil chamber 117 from leaking through the gap between the inner circumferential wall of the piston 112 and the first mounting portion 1164.

[0081] Specifically, if Figure 4 and Figure 12 As shown, the piston assembly further includes a disc spring 113 and a retaining spring 114. The retaining spring 114 is fixedly mounted on the first mounting portion 1164. The disc spring 113 is mounted on the first mounting portion 1164 and is located between the retaining spring 114 and the piston 112. The two ends of the disc spring 113 abut against the retaining spring 114 and the piston 112 in a one-to-one correspondence. This arrangement enables, when hydraulic oil is delivered into the hydraulic oil chamber 117 through the first central oil hole 11631, the hydraulic oil in the hydraulic oil chamber 117 pushes the piston 112 to slide relative to the cylinder body 116 in a direction away from the first bearing connection portion 1163. During this process, the disc spring 113 is squeezed and elastically deformed. When the hydraulic oil in the hydraulic oil chamber 117 is discharged through the first central oil hole 11631, the elastic restoring force of the disc spring 113 drives the piston 112 to slide relative to the cylinder body 116 in a direction toward the first bearing connection portion 1163.

[0082] Specifically, if Figure 3 、 Figure 4 and Figure 12 As shown, the cylinder assembly 11 further includes a first locating pin 111. A first pin hole is provided on the cylinder body 116, extending axially therethrough. A first guide groove is provided on the end surface of the piston 112, near the first bearing connection portion 1163. One end of the first locating pin 111 is inserted into the cylinder body 116 with an interference fit, while the other end of the first locating pin 111 is inserted into the first guide groove in a sliding manner. This ensures the sealing of the hydraulic oil chamber 117 and limits the piston 112 to moving only axially and not rotating about its central axis.

[0083] More specifically, Figure 3 、 Figure 4 and Figure 12As shown, there are at least two first positioning pins 111, which are spaced apart on the cylinder body 116. Correspondingly, there are at least two first guide limiting grooves, which are arranged in a one-to-one correspondence with the at least two first positioning pins 111 and the at least two first guide limiting grooves.

[0084] Among them, such as Figure 6 、 Figure 7 and Figure 11-13 As shown, the stopper shaft assembly 12 includes a stopper shaft body 125 and a second bearing 124 .

[0085] Specifically, if Figure 6 and Figure 11-13 As shown, the first end of the blocking shaft body 125 along the axial direction is provided with a second bearing connection part 1251 and forms a second limiting surface. The second bearing 124 is fixedly sleeved on the outer periphery of the second bearing connection part 1251 and abuts against the second limiting surface along the axial direction.

[0086] Specifically, if Figure 6 and Figure 11-13 As shown, the first axial end of the block shaft body 125 is further provided with a second mounting portion 1252, which is located between the second bearing connection portion 1251 and the second end of the block shaft body 125. The block shaft assembly 12 also includes a driving plate 122, a driven plate 121, and an elastic pad 123. The elastic pad 123 is sandwiched between the driving plate 122 and the driven plate 121 and partially located on the outer peripheries of the driving plate 122 and the driven plate 121. The second mounting portion 1252 is sandwiched between the driving plate 122 and the driven plate 121 and located on the inner periphery of the driving plate 122. The threaded portion of the bolt 161 of the second fastener 16 sequentially passes through the driven plate 121, the second mounting portion 1252, and the driving plate 122, and is threadedly connected to the nut 162 of the second fastener 16. The piston 112 can axially abut the driving plate 122, and the driven plate 121 can axially abut the pressure plate 133 of the pressure plate assembly 13.

[0087] More specifically, a bearing mounting groove is recessed into the axial end surface of the first mounting portion 1164. The second bearing 124 is positioned within the bearing mounting groove, and the outer ring of the second bearing 124 is fixedly connected to the inner circumferential wall of the bearing mounting groove, thereby defining the relative position of the stopper shaft assembly 12 and the cylinder body assembly 11.

[0088] like Figure 12 As shown, when the piston 112 applies axial force to the active plate 122, the elastic pad 123 is elastically deformed, causing the active plate 122 to approach the driven plate 121 along its own axial direction, and pressing the driven plate 121 against the pressure plate 133; after the axial force applied to the active plate 122 is removed, the elastic restoring force of the elastic pad 123 can drive the active plate 122 away from the driven plate 121 and return to its initial state.

[0089] More specifically, there are multiple second fasteners 16 , and the multiple second fasteners 16 are distributed at intervals along the circumference of the active plate 122 . In this embodiment, the multiple second fasteners 16 are evenly distributed at intervals along the circumference of the active plate 122 .

[0090] More specifically, Figure 11 and Figure 12 As shown, the central axis of the active plate 122, the central axis of the driven plate 121, the central axis of the elastic pad 123, the central axis of the blocking shaft body 125, the central axis of the piston assembly and the central axis of the cylinder body 116 are all collinear.

[0091] Alternatively, as Figure 6 、 Figure 7 、 Figure 11 and Figure 12 As shown, the block shaft body 125 is provided with a second central oil hole 1253. One end of the second central oil hole 1253 is connected to the bearing mounting groove, and the other end is connected to a hydraulic oil source. This allows lubricating oil to be delivered to the bearing mounting groove to lubricate the second bearing 124. In this embodiment, the second central oil hole 1253 extends axially along the block shaft body 125 to both ends of the block shaft body 125.

[0092] Among them, such as Figure 11 and Figure 12 As shown, the pressure plate assembly 13 includes a pressure plate 133 detachably connected to the cylinder body 116. A first accommodating chamber is formed between the pressure plate 133 and the cylinder body 116. The first mounting portion 1164, the piston assembly, the second bearing 124, the driving plate 122, the driven plate 121, the elastic pad 123, the second fastener 16, and the second bearing connection portion 1251 and second mounting portion 1252 of the block shaft body 125 are all located within the first accommodating chamber. It will be appreciated that the hydraulic oil chamber 117 is part of the first accommodating chamber.

[0093] Specifically, if Figure 11 and Figure 12 As shown, the pressure plate 133 is provided with a process hole 1332, and the second end of the stop shaft body 125 in the axial direction extends out of the pressure plate 133 through the process hole 1332. This allows the stop shaft body 125 to transmit power to the transmission structure connected thereto. Figure 11 and Figure 12 As shown, the central axis of the process hole 1332, the central axis of the pressure plate 133 and the central axis of the cylinder body 116 are all collinear.

[0094] Specifically, if Figure 9-12 As shown, a third bearing connection portion 1331 and a third limiting surface are provided on the end of the pressure plate 133 away from the cylinder body 116, and the inner ring of the third bearing 132 is fixedly sleeved on the third bearing connection portion 1331 and axially abuts against the third limiting surface.

[0095] Specifically, if Figure 9-12 As shown, the pressure plate assembly 13 further includes a second locating pin 131. The pressure plate 133 is provided with a second pin hole extending axially therethrough. The cylinder body 116 is provided with a second guide stopper groove. One axial end of the second locating pin 131 is inserted into the second pin hole with an interference fit, while the other axial end of the second locating pin 131 engages with the second guide stopper groove. This allows the relative position of the pressure plate 133 and the cylinder body 116 to be defined, facilitating the integrated assembly of the pressure plate 133, the cylinder body 116, and the ring gear 14.

[0096] More specifically, Figure 9-12 As shown, the number of the second positioning pins 131 is at least two, the number of the second guide limiting grooves is at least two, and the at least two second positioning pins 131 and the at least two second guide limiting grooves are arranged in a one-to-one correspondence.

[0097] Specifically, if Figure 11 and Figure 12 As shown, the first locking member passes through the pressure plate 133 and is threadedly connected to the cylinder body 116 and the ring gear 14 in sequence. The central axis of the ring gear 14 is collinear with the central axis of the cylinder body 116. Furthermore, the first locking member is a screw. Furthermore, there are multiple first locking members, which are spaced apart along the circumference of the pressure plate 133.

[0098] like Figure 11 and Figure 12 As shown, the working principle of the hydraulic clutch assembly 1 is:

[0099] When hydraulic oil is injected into hydraulic oil chamber 117 through first central oil hole 11631, the hydraulic oil pushes piston 112 against active plate 122, exerting an axial force on active plate 122. Active plate 122 transmits the axial force to passive plate 121, causing passive plate 121 to press against pressure plate 133, thereby stopping the shaft block body 125 from rotating about its own central axis. During this process, both disc spring 113 and elastic pad 123 undergo elastic deformation.

[0100] As the hydraulic oil in the hydraulic oil chamber 117 flows out through the first center oil hole 11631, the elastic restoring force of the disc spring 113 drives the piston 112 to move toward the cylinder body 116 and return to its initial state, and the elastic restoring force of the elastic pad 123 drives the active plate 122 to move away from the driven plate 121 and return to its initial state.

[0101] Among them, such as Figure 1-12As shown, the hydraulic clutch assembly assembly line includes a gear ring carrying pallet 2, a cylinder body carrying pallet 3, a baffle bearing pallet 4, a pressure plate carrying pallet 5, a storage rack, a cache workbench, a bearing pressing device, a positioning pin pressing device, a fastener loading device, a fastener screwing device, a conveyor line, a robotic arm and a cantilever crane.

[0102] Among them, such as Figure 1 、 Figure 2 、 Figure 11 and Figure 12 As shown, the ring gear carrier tray 2 can limit and support the ring gear 14 of the hydraulic clutch assembly 1, and can also limit and support the cylinder body 116. This allows the cylinder body assembly 11, the gear shaft assembly 12, the pressure plate assembly 13, and the ring gear 14 to be assembled into the hydraulic clutch assembly 1 on the ring gear carrier tray 2.

[0103] Specifically, if Figure 1 and Figure 2 As shown, the gear ring carrying tray 2 includes a first tray body 21, a first support portion 22 protruding from the top of the first tray body 21, at least two first limiting columns 23 protruding from the top of the first support portion 22, and at least two second limiting columns 24 protruding from the top of the first support portion 22. The at least two first limiting columns 23 and the at least two second limiting columns 24 are distributed at intervals along the circumference of the first support portion 22; the first limiting column 23 is used to be plugged into and matched with the gear ring 14 so that the gear ring 14 can be limited and supported on the first support portion 22; the second limiting column 24 is used to pass through the gear ring 14 and be plugged into and matched with the cylinder body 116 so that the cylinder body 116 can be limited and supported on the gear ring 14.

[0104] The first insertion hole 141 on the ring gear 14 is plugged into and matched with the first limiting column 23, so that the ring gear 14 can be limited and supported above the first support part 22; the second insertion hole 142 on the ring gear 14 and the first slot on the cylinder body 116 are both plugged into and matched with the second limiting column 24, so that the relative position of the ring gear 14 and the cylinder body 116 can be defined, and the cylinder body 116 is supported on the ring gear 14, which is convenient for subsequent assembly to form the hydraulic clutch assembly 1; secondly, by setting the first supporting part 22, when the ring gear 14 is supported on the first supporting part 22, the lower end of the ring gear 14 in the axial direction is spaced apart from the top of the first tray body 21, thereby facilitating the transportation of the ring gear 14 to the ring gear carrying tray 2, and facilitating the removal of the ring gear 14 from the ring gear carrying tray 2, which can effectively avoid damage to the ring gear 14 and / or the ring gear carrying tray 2.

[0105] It is understandable that if Figure 1 and Figure 2 As shown, the axial length of the second limiting column 24 is greater than the axial length of the first limiting column 23 .

[0106] In this embodiment, Figure 1 and Figure 2 As shown, the two first limiting posts 23 and the two second limiting posts 24 are provided as an example. The two first limiting posts 23 and the two second limiting posts 24 are distributed on the same circumference.

[0107] Optionally, in this embodiment, the first support portion 22 is detachably connected to the first tray body 21 , so that the first support portion 22 of different sizes can be adaptively replaced according to the different sizes of the gear ring 14 , thereby improving the versatility of the gear ring carrying tray 2 .

[0108] Optionally, in this embodiment, the first limiting column 23 is detachably inserted into the top of the first support portion 22. The second limiting column 24 is detachably inserted into the top of the first support portion 22. This allows the setting positions and quantities of the first limiting column 23 and the second limiting column 24 to be adaptively adjusted according to the setting positions and quantities of the first insertion holes 141 and the second insertion holes 142 on the gear ring 14, thereby further improving the versatility of the gear ring carrying tray 2. Specifically, a plurality of second slots are recessed in the top of the first support portion 22, and the plurality of second slots are spaced apart on the first support portion 22, wherein a portion of the second slots are used to insert the first limiting column 23, and the remaining portion of the second slots are used to insert the second limiting column 24.

[0109] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, the first support portion 22 is annular, and the first tray body 21 is further provided with a first avoidance hole 211 extending through the first tray body 21 in the thickness direction. The first support portion 22 is located on the outer periphery of the first avoidance hole 211. The aperture of the first avoidance hole 211 is larger than the outer diameter of the first bearing 115. This allows the ring gear 14 to be positioned and supported on the first support portion 22, and the cylinder body assembly 11 to be positioned and supported on the ring gear 14, thereby avoiding interference between the first tray body 21 and the first bearing 115, and between the first tray body 21 and the first bearing connecting portion 1163. In other embodiments, the height of the first support portion 22 can be increased to avoid interference between the first tray body 21 and the first bearing 115 when the cylinder body assembly 11 is positioned and supported on the ring gear 14, and to avoid interference between the first tray body 21 and the first bearing 115.

[0110] Among them, such as Figure 3 、 Figure 4 and Figure 12 As shown, the oil cylinder body carrying tray 3 is used to limit and support the oil cylinder body 116 of the hydraulic clutch assembly 1. It makes it possible to assemble the oil cylinder body assembly 11 on the oil cylinder body carrying tray 3.

[0111] Specifically, if Figure 3 and Figure 4As shown, the cylinder body supporting tray 3 includes a second tray body 31, a second support portion 32 protruding from the top of the second tray body 31, and at least two limit blocks 33 protruding from the top of the second support portion 32. The at least two limit blocks 33 are distributed at intervals along the circumference of the second support portion 32. The limit blocks 33 are used to plug and cooperate with the cylinder body 116 so that the cylinder body 116 can be limited and supported on the second support portion 32.

[0112] Specifically, if Figure 3 and Figure 4 As shown, one axial end of the cylinder body 116 is recessed with at least two third slots 1161, which are spaced apart along the circumference of the cylinder body 116. The other axial end of the cylinder body 116 is formed with a first bearing connection portion 1163. The at least two third slots 1161 are provided in a one-to-one correspondence with the at least two stop blocks 33 and can be plugged in and mated with each other.

[0113] Before assembling the first locating pin 111, piston 112, disc spring 113, retaining ring 114, sealing ring 118 and first bearing 115 to the cylinder body 116, first move the cylinder body 116 to the cylinder body carrying tray 3, so that at least two third slots 1161 are plugged into and matched with at least two limit blocks 33 in a one-to-one manner, and the first bearing connecting portion 1163 is located at the top of the cylinder body 116 in the axial direction, and then press the first bearing 115 into the first bearing connecting portion 1163, press the first locating pin 111 into the first pin hole of the cylinder body 116, and make the first locating pin 111 partially extend out of the bottom of the first pin hole.

[0114] More specifically, Figure 4 As shown, at least two fourth limiting posts 34 are protruded from the top of the second tray body 31 and / or the top of the second support portion 32, and the cylinder body 116 is provided with at least two third insertion holes 1162 extending axially therethrough. The at least two fourth limiting posts 34 are plugged in and matched with the at least two third insertion holes 1162 in a one-to-one correspondence. It is understood that when the at least two third insertion holes 1161 are plugged in and matched with the at least two limiting blocks 33 in a one-to-one correspondence, the at least two fourth limiting posts 34 are plugged in and matched with the at least two third insertion holes 1162 in a one-to-one correspondence, and the cylinder body 116 is supported on the second support portion 32, thereby facilitating the assembly of the piston 112, disc spring 113, retaining ring 114, and sealing ring 118 to the cylinder body 116. After the first bearing 115 is pressed into the first bearing connecting portion 1163 and the first locating pin 111 is pressed into the first pin hole of the cylinder body 116, the cylinder body 116 is flipped over to make the at least two fourth limiting columns 34 and the at least two third insertion holes 1162 respectively plugged in and matched again. When the at least two fourth limiting columns 34 and the at least two third insertion holes 1162 are respectively plugged in and matched, the cylinder body 116 is supported on the second supporting portion 32.

[0115] Optionally, when fourth retaining posts 34 are provided on the top of the second tray body 31, the fourth retaining posts 34 are removably inserted into the top of the second tray body 31. This arrangement allows the location and number of the fourth retaining posts 34 to be adaptively adjusted based on the location and number of the third insertion holes 1162 on the cylinder body 116, thereby enhancing the versatility of the cylinder body supporting tray 3. Specifically, a plurality of fourth slots are recessed into the top of the second tray body 31 and / or the top of the second support portion 32, and are used to receive the fourth retaining posts 34.

[0116] Optionally, the second tray body 31 is further provided with a fifth limiting post, a sixth limiting post, and a seventh limiting post at intervals. The fifth limiting post is used to fit the disc spring 113, the sixth limiting post is used to fit the retaining spring 114, and the seventh limiting post is used to fit the sealing ring 118. This allows the disc spring 113, retaining spring 114, and sealing ring 118 to be confined to the second tray body 31, thereby further facilitating the assembly of the disc spring 113, retaining spring 114, and sealing ring 118 to the cylinder body 116.

[0117] In this embodiment, the fifth limiting post and the seventh limiting post are both cylindrical in shape. In other embodiments, the fifth limiting post and / or the seventh limiting post may also be truncated cone-shaped.

[0118] In this embodiment, the sixth limiting post is exemplarily configured to be in the shape of a frustum. In other embodiments, the sixth limiting post may also be configured to be in the shape of a cylinder.

[0119] Further optionally, the fifth limiting post, the sixth limiting post, and the seventh limiting post are all detachably connected to the top of the second tray body 31. This allows the fifth limiting post, the sixth limiting post, and the seventh limiting post to be adaptively replaced with those of different sizes based on the sizes of the disc spring 113, the retaining ring 114, and the sealing ring 118.

[0120] In this embodiment, Figure 4 As shown, the second support portion 32 is annular. The interior of the second support portion 32 forms a structure of an escape space to escape the central area of ​​the oil cylinder body 116.

[0121] Among them, such as Figure 5-7As shown, the stopper shaft supporting tray 4 includes a third tray body 41, a limiting structure connected to the third tray body 41 and located above the top of the third tray body 41, a stopper shaft insertion limiting hole 421 is formed in the center of the limiting structure, and at least two fastener limiting grooves 441 are recessed on the upper end surface of the limiting structure. The at least two fastener limiting grooves 441 are spaced apart along the circumference of the limiting structure and are all located on the periphery of the stopper shaft insertion limiting hole 421. The stopper shaft insertion limiting hole 421 is used to insert the stopper shaft body 125, and the fastener limiting groove 441 is used to limit and support the bolt 161 of the second fastener 16.

[0122] Before assembling the stop shaft assembly 12, first insert the heads of at least two bolts 161 into the at least two fastener limiting grooves 441 one by one, so that the threaded portion of each bolt 161 is located above the corresponding head; then stack the driven plate 121 on the head of each bolt 161, and make the threaded portion of each bolt 161 pass through the driven plate 121; then stack the elastic pad 123 on the driven plate 121, insert the stop shaft body 125 into the stop shaft plug-in limiting hole 421 and make the stop shaft body 125 supported between the driven plate 121 The threaded portion of each bolt 161 is passed through the block shaft body 125, and the second bearing connection portion 1251 of the block shaft body 125 is located at the top of the block shaft body 125 along the axial direction of the block shaft body 125; then the active plate 122 is stacked on the elastic pad 123 and the block shaft body 125, and the threaded portion of each bolt 161 is passed through the active plate 122; then the nut 162 is screwed on the threaded portion of the bolt 161; and then the second bearing 124 is pressed into the second bearing connection portion 1251 to assemble to form the block shaft assembly 12.

[0123] In this embodiment, Figure 5-7 As shown, the shape of the fastener limiting groove 441 is the same as the shape of the head of the bolt 161, and the same as the shape of the nut 162. The size of the fastener limiting groove 441 is the same as the size of the head of the bolt 161, and the same as the size of the nut 162. The aperture of the stop shaft insertion limiting hole 421 is greater than or equal to the outer diameter of the second bearing 124. With this arrangement, after the head of the bolt 161 is inserted into the fastener limiting groove 441, the bolt 161 will not rotate around its own central axis during the process of screwing the nut 162, thereby effectively tightening the nut 162 to the bolt 161; secondly, when the driven plate 121 is stacked on the head of each bolt 161, the upper end surface of the limiting structure supports the driven plate 121, thereby enhancing the support effect on the stop shaft assembly 12; secondly, this arrangement allows the stop shaft assembly 12 to still be limited and supported on the stop shaft supporting tray 4 after being flipped.

[0124] Specifically, if Figure 5-7As shown, the limiting structure includes a first limiting ring 42 which is detachably connected to the third pallet body 41 and is located above the top of the third pallet body 41, and the shaft plug-in limiting hole 421 is arranged at the center of the first limiting ring 42 and passes through the first limiting ring 42; the first limiting ring 42 is provided with a limiting ring accommodating groove on the upper end face along the axial direction, and the limiting structure also includes a second limiting ring, which is detachably mounted on the outer periphery of the first limiting ring 42 and is limited to the limiting ring accommodating groove; the second limiting ring is provided with a fastener limiting groove 441 on the upper end face along the axial direction.

[0125] The first limiting ring 42 is detachably connected to the third pallet body 41, so that the first limiting ring 42 can be replaced according to the different sizes of the blocking shaft body 125, thereby effectively improving the versatility of the blocking shaft supporting pallet 4; secondly, it is convenient to adjust the setting height of the limiting structure according to the different sizes of the blocking shaft body 125.

[0126] A second limiting ring is provided that is detachably mounted on the first limiting ring 42, so that when the second limiting ring is connected to the first limiting ring 42, the relative position of the second limiting ring and the first limiting ring 42 is fixed, thereby preventing the bolt 161 from being displaced; secondly, the second limiting ring is provided that is detachably connected to the first limiting ring 42, so that different second limiting rings can be replaced according to the number and distribution position of the bolts 161 on the blocking shaft assembly 12, thereby further improving the versatility of the blocking shaft supporting tray 4.

[0127] Specifically, if Figure 5-7 As shown, the baffle bearing tray 4 further includes a support column 43 positioned between the first limiting ring 42 and the third tray body 41. One end of the support column 43 is detachably connected to the first limiting ring 42, and the other end of the support column 43 is detachably connected to the third tray body 41. This allows the height of the limiting structure to be adjusted according to the different sizes of the baffle body 125. Optionally, there are multiple support columns 43, with the multiple support shafts spaced apart along the circumference of the first limiting ring 42, to further enhance the support performance of the support and limiting structure.

[0128] Alternatively, as Figure 5-7 As shown, the third tray body 41 is provided with a second avoidance hole 411 extending axially through the first retaining ring 42. The central axis of the second avoidance hole 411 is collinear with the central axis of the stop shaft insertion and limiting hole 421, and the diameter of the second avoidance hole 411 is greater than or equal to the diameter of the stop shaft insertion and limiting hole 421. Along the axial direction of the first retaining ring 42, even for the larger stop shaft body 125, the third tray body 41 is effectively prevented from interfering with the insertion and mating of the stop shaft body 125 with the stop shaft insertion and limiting hole 421.

[0129] Alternatively, as Figure 5As shown, the second retaining ring includes at least two sub-ring segments 44, which are sequentially distributed along the circumference of the second retaining ring and can be spliced ​​together to form the second retaining ring. At least one of the sub-ring segments 44 is provided with a fastener retaining groove 441. This arrangement allows the number of sub-ring segments 44 to be selectively increased or decreased based on the density of bolts 161 on the retaining shaft assembly 12, thereby further improving the versatility of the retaining shaft supporting tray 4.

[0130] Specifically, if Figure 5-7 As shown, the portion of the elastic pad 123 that radially extends outward from the outer periphery of the driven plate 121 is provided with at least two notches 1231. These at least two notches 1231 are spaced apart along the circumference of the elastic pad 123. The retaining structure also includes at least two eighth retaining posts 45 connected to the third tray body 41. These at least two eighth retaining posts 45 are spaced apart along the circumference of the first retaining ring 42 and are both located on the outer periphery of the first retaining ring 42. The at least two eighth retaining posts 45 are configured to engage and position themselves axially with the at least two notches 1231. This prevents the shaft assembly 12 from rotating about its own central axis and further prevents the bolt 161 from shifting out of position.

[0131] Optionally, the eighth limiting post 45 is detachably inserted into the third tray body 41 , so that the position of the eighth limiting post 45 on the third tray body 41 can be adaptively adjusted according to elastic pads 123 of different sizes.

[0132] Among them, such as Figure 8-10 As shown, the pressure plate carrying tray 5 includes a fourth tray body 51, and a third support portion 52 protruding from the top of the fourth tray body 51. The top of the third support portion 52 is recessed with an avoidance groove 53 and protrudes with at least two third limiting columns 54. The third limiting columns 54 are used to be plugged in and matched with the pressure plate 133 so that the pressure plate 133 can be limited and supported on the third support portion 52. The avoidance groove 53 is used to be plugged in with the second positioning pin 131 on the pressure plate 133.

[0133] After the fourth socket on the pressure plate 133 is inserted and matched with at least two third limiting columns 54, and the third bearing connecting part 1331 of the pressure plate 133 is located at the top of the pressure plate 133 along the axial direction of the pressure plate 133, the third bearing 132 is pressed into the third bearing connecting part 1331 from top to bottom along the axial direction of the pressure plate 133, and the second positioning pin 131 is pressed into the second pin hole of the pressure plate 133, and the second positioning pin 131 is partially extended from the bottom of the second pin hole and extended into the avoidance groove 53.

[0134] Specifically, if Figure 8-10 As shown, the number of the avoidance grooves 53 is at least two, the number of the second positioning pins 131 is at least two, and the at least two avoidance grooves 53 are arranged in a one-to-one correspondence with the at least two second positioning pins 131.

[0135] Optionally, the third support portion 52 is detachably connected to the fourth tray body 51 , so that different third support portions 52 can be adaptively replaced according to different sizes of the pressure tray 133 , thereby effectively improving the versatility of the pressure tray 5 .

[0136] Optionally, the third limiting posts 54 are removably inserted into the top of the third support portion 52. This allows the location and number of the third limiting posts 54 to be adaptively adjusted based on the location and number of the fourth insertion holes on the pressure plate 133, thereby further enhancing the versatility of the pressure plate carrying tray 5. Specifically, at least two fifth slots are recessed into the top of the third support portion 52, spaced apart and arranged on the third support portion 52. The fifth slots are used to insert the third limiting posts 54.

[0137] In this embodiment, Figure 9 As shown, the third support portion 52 is annular. In other embodiments, the third support portion 52 may also be cylindrical.

The specific structure of the holding rack belongs to the existing technology and will not be repeated here.

[0140] It is understandable that the number of the holding racks, the number of the holding boxes on the holding racks, and the number of the second receiving cavities of each holding box are adaptively adjusted according to actual working conditions.

[0141] Among them, the cache workbench is used to cache the ring gear bearing tray 2, the cylinder body bearing tray 3, the baffle shaft bearing tray 4 and the pressure plate bearing tray 5.

The specific structure of the fastener screwing device belongs to the prior art and will not be described in detail here.

[0146] The conveyor line is used to transport the ring gear carrier tray 2, the cylinder body carrier tray 3, the stopper shaft carrier tray 4, and the pressure plate carrier tray 5. This allows the cylinder body carrier tray 3 to be transported to the bearing press-fitting station and the locating pin press-fitting station, the stopper shaft carrier tray 4 to be transported to the bearing press-fitting station and the fastener tightening station, the pressure plate carrier tray 5 to be transported to the bearing press-fitting station and the locating pin press-fitting station, and the ring gear carrier tray 2 to be transported to the fastener tightening station.
