Description

Technical Field

[0001] The invention relates to the technical field related to equipment parts assembly, in particular to a gasket and gear assembly machine. Background Art

[0002] It is well known that a planetary gear set is a compound gear system consisting of multiple planetary gears, a sun gear, an inner ring gear and a planet carrier, and is usually used for transmission and speed change. When the planetary gear set is working, the sun gear drives the planetary gears, and the planetary gears mesh with the inner ring gear at the same time. Depending on the connection method between the input and output, the output speed and torque can be changed.

[0003] When assembling a planetary gear set, multiple planetary gears need to be installed on the planetary carrier, and gaskets need to be installed at both axial ends of each planetary gear. For example, the patent with announcement number CN119238068A, announcement date January 3, 2025, and name "A planetary gear automatic installation device" includes: an installation station for installing a planetary carrier, and the planetary carrier is rotatably arranged at the installation station; a feeding module for feeding planetary gears into the window of the planetary carrier, including a feeding track and a feeding rack moving along the feeding track; a material loading module, including a gear loading module and a gasket loading module, which are respectively used for loading planetary gears and gaskets onto the feeding rack. The automated installation equipment provided by the present invention realizes the manual configuration and assembly of the components of the planetary gear transmission structure in sequence through the cooperation between the installation station and the feeding module and multiple loading modules. The positioning accuracy of the components relative to each other and the stability during combined installation are greatly improved by replacing people with machines, thereby improving the yield and efficiency of the assembly work of the planetary gear transmission structure, effectively controlling labor costs, and being more conducive to production management and control.

[0004] The disadvantage of the above-mentioned prior art is that the installation of the planetary gears, planetary carriers and gaskets requires loading in multiple times and the operation is performed at one station. Obviously, this operation method will have an adverse effect on the assembly efficiency of the planetary gear set. Summary of the invention

[0005] The purpose of the present invention is to provide a gasket and gear assembly machine to solve the technical problems in the related art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A gasket and gear assembly machine comprises an equipment frame assembly, on which a mounting base for placing a planetary carrier, a gasket loading mechanism and a gear loading mechanism are arranged, and also comprises a conveyor line assembly, on which a first installation station and a second installation station are arranged in sequence in the conveying direction, and the mounting base is arranged on the conveyor line assembly; the gasket loading mechanism comprises a lower die group for loading a lower gasket and an upper die group for loading an upper gasket; the lower die group is arranged at the first installation station; during operation, the lower die group installs the lower gasket at a specified position on the planetary carrier; the upper die group and the gear loading module are arranged together at the second installation station; during operation; in the first stroke, the upper die group installs the upper gasket on the planetary gear; in the second stroke, the gear loading module installs the planetary gear at the position of the lower gasket on the planetary carrier.

[0008] As mentioned above, the planetary gear is composed of a gear, a retaining frame and a needle bearing, and the equipment frame assembly is provided with a detection mechanism for detecting the composition of the planetary gear.

[0009] As mentioned above, each of the installation bases is provided with a plurality of discharge troughs for placing lower gaskets and upper gaskets.

[0010] As mentioned above, the lower gasket is placed in the corresponding discharge trough in the same manner as when it is installed on the planetary frame; the upper gasket is placed in the corresponding discharge trough in the same manner as when it is installed on the planetary gear.

[0011] As mentioned above, the first combing mechanism is arranged in each of the material discharge grooves. Based on the combing effect of the first combing mechanism, a plurality of lower gaskets are arranged axially spaced apart in the corresponding material discharge grooves.

[0012] As mentioned above, the first combing mechanism includes two belt transmission mechanisms arranged along any radial direction in the material discharge trough, and a number of combing spacers are arranged in sequence along the conveying track on the conveyor belt of each belt transmission mechanism. The number of combing spacers on the two belt transmission mechanisms correspond to each other one by one, and the space between two combing spacers at adjacent positions along the conveying direction is used to place the lower gasket.

[0013] As mentioned above, each of the belt transmission mechanisms is also arranged with a one-way transmission mechanism; when the lower gasket is placed in the discharge trough, the one-way transmission mechanism releases the restriction on the belt transmission mechanism; when the lower module grabs the lower gasket from the discharge trough, based on the restriction of the one-way transmission mechanism, the belt transmission mechanism transports the lower gasket in the direction away from the discharge trough.

[0014] As mentioned above, the lower mold assembly includes a driving mechanism and a grabbing mechanism arranged at the power output end of the driving mechanism, the grabbing mechanism includes a grabbing arm, and two clamping blocks are provided on the grabbing arm along a radial sliding direction of the lower gasket. Based on the driving force of the driving mechanism, the two clamping blocks clamp the inner ring of the lower gasket in a manner far away from each other.

[0015] As mentioned above, the two clamping blocks are provided with clamping grooves in contact with the clamped lower gasket, and the outer shape structure of the clamping grooves matches the outer shape structure of the inner ring of the lower gasket.

[0016] As mentioned above, each of the clamping blocks is provided with a second combing mechanism, and the two clamping blocks can grab a number of lower gaskets corresponding to the number of lower gaskets required to be installed on each planetary frame at one time. Based on the combing effect of the second combing mechanism, the two lower gaskets at adjacent positions are arranged at intervals.

[0017] The beneficial effect of the present invention is that by arranging the first installation station and the second installation station on the conveyor line assembly, in the conveying direction of the conveyor line assembly, when the second installation station sequentially assembles the upper gasket and the planetary gear, and the planetary gear and the planetary carrier, the first installation station installs the lower gasket on the next planetary carrier. Obviously, compared with the single-station operation, the double-station operation can better improve the assembly efficiency of the planetary gear set. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig.11 The present invention is further described in detail.

[0033] An embodiment of the present invention provides a gasket and gear assembly machine, including an equipment frame assembly 1, on which an installation base 2 for placing a planetary carrier 9, a gasket loading mechanism 3 and a gear loading mechanism 4 are arranged, and also includes a conveyor line assembly 5, on which a first installation station and a second installation station are arranged in sequence in its conveying direction, and the installation base 2 is arranged with several on the conveyor line assembly 5; the gasket loading mechanism 3 includes a lower die group for loading a lower gasket 7 and an upper die group for loading an upper gasket 6; the lower die group is arranged at the first installation station; during operation, the lower die group installs the lower gasket 7 at a specified position on the planetary carrier 9; the upper die group and the gear loading module are arranged at the second installation station together; during operation; in the first stroke, the upper die group installs the upper gasket 6 on the planetary gear 8; in the second stroke, the gear loading module installs the planetary gear 8 at the position of the lower gasket 7 on the planetary carrier 9.

[0034] Specifically, when assembling the planetary gear 8 set, it is necessary to first install the gasket and the planetary gear 8 on the planetary carrier 9, and then install the rotating shaft in the middle of the planetary gear 8. For the convenience of description and understanding, the planetary gear 8 is installed on the planetary carrier 9 in such a way that its axial direction is parallel to the vertical direction. The gasket at the axial lower end of the planetary gear 8 is the lower gasket 7, and the gasket at the axial upper end is the upper gasket 6. The upper gasket 6 has the same structure as the lower gasket 7, and is symmetrically arranged at both ends of the axial direction of the planetary gear 8. During the assembly process, the planetary carrier 9 will be placed on the mounting base 2 first. The mounting base 2 is a plate-like structure, on which a clamping mechanism for clamping the planetary carrier 9 and a mechanism for driving the planetary carrier 9 to rotate will be correspondingly arranged. The mechanism for intermittent rotation is the prior art and will not be described in detail. During assembly, the gasket feeding mechanism 3 will first place the lower gasket 7 in the circumferential direction in the designated positions on the planetary carrier 9, and then place the upper gasket 6 on the axial upper end of the planetary gear 8, and then place the planetary gear 8 and the upper gasket 6 together on the planetary carrier 9 at the position corresponding to the lower gasket 7. In this way, the assembly of the gasket, planetary gear 8 and planetary carrier 9 is completed. However, the disadvantage is that the installation of the planetary gear 8, planetary carrier 9 and gasket requires multiple loading and the operation is performed at one workstation. Obviously, this operation method will have an adverse effect on the assembly efficiency of the planetary gear 8 group.

[0035] Based on the above problems, in this embodiment, a conveyor line assembly 5 (i.e., a conveying mechanism) is arranged on the equipment frame assembly 1, wherein a plurality of mounting bases 2 are arranged in the conveying direction of the conveyor line assembly 5, and a first installation station and a second installation station are arranged in the conveying direction, and the gasket feeding mechanism 3 is split into a lower mold group for feeding the lower gasket 7 and an upper mold group for feeding the upper gasket 6, the lower mold group is arranged at the first installation station, and the upper mold group and the gear feeding mold group are arranged together at the second installation station.

[0036] During the assembly operation, the planetary gears 8, the planetary carrier 9, the upper gasket 6 and the lower gasket 7 are manually supplemented. The lower mold group includes a part for placing the lower gasket 7 and a part for grabbing each lower gasket 7. The upper mold group includes a part for placing the upper gasket 6 and a part for grabbing each upper gasket 6. The gear feeding mold group includes a part for placing the planetary gear 8 and a part for grabbing each planetary gear 8. At the beginning of the assembly operation, the first planetary carrier 9 is placed on the first mounting base 2 in the conveying direction of the conveyor line assembly 5. At this time, the first mounting base 2 is in the first mounting station. The mounting base 2 is equipped with a jacking mechanism and an intermittent rotation mechanism. The intermittent rotation mechanism drives the planetary carrier 9 to rotate 90 degrees each time, that is, the lower mold group will first grab a lower gasket 7 and send it to the specified position on the planetary carrier 9. The intermittent rotation mechanism drives the planetary carrier 9 to rotate 90 degrees. The lower mold group then sends the second lower gasket 7 to the specified position of the planetary carrier 9. In this way, according to the number of lower gaskets 7 that need to be installed on the planetary carrier 9, the intermittent rotation mechanism drives the planetary carrier 9 to rotate the corresponding number of times until all the required gaskets 7 on the planetary carrier 9 are installed. The positions where the lower gaskets 7 are to be installed are all installed with the lower gaskets 7, and then the conveyor line assembly 5 conveys the first installation base 2 to the second installation station, and the second installation base 2 will move to the first installation station, and then the gear loading module will first place a planetary gear 8 on the installation base 2, and the upper module will grab the first upper gasket 6 and install it on the axial upper end of the planetary gear 8, and then the gear loading module will push the planetary gear 8 and the upper gasket 6 into the position corresponding to each lower gasket 7 on the planetary carrier 9, until all the positions where the lower gaskets 7 are installed are installed with planetary gears 8, then the conveyor line assembly 5 will convey the first installation base 2 to the position for installing the rotating shaft, and the second installation base 2 will arrive at the second installation station, and the third installation base 2 will arrive at the first installation station, the specific installation process is the same as mentioned above, when the last installation base 2 is in the rotating shaft installation position and the planetary gear 8 group has been assembled, the conveyor line assembly 5 will drive all the installation bases 2 back to the initial position, and then continue to assemble the next batch of planetary gear 8 groups according to the above working process.

[0037] The beneficial effect of this embodiment is that by arranging the first installation station and the second installation station on the conveyor line assembly 5, in the conveying direction of the conveyor line assembly 5, when the second installation station sequentially assembles the upper gasket 6 and the planetary gear 8, and the planetary gear 8 and the planetary carrier 9, the first installation station installs the lower gasket 7 on the next planetary carrier 9. Obviously, the double-station operation can better improve the assembly efficiency of the planetary gear 8 group compared with the single-station operation.

[0038] Preferably, the planetary gear 8 is composed of a gear, a retaining frame and a needle bearing, and a detection mechanism for detecting the composition of the planetary gear 8 is provided on the equipment frame assembly 1; specifically, in order to avoid waste during the assembly process of the planetary gear 8 group, the present embodiment arranges a detection mechanism on the equipment frame assembly 1, which can detect whether there are any missing components of the planetary gear 8. If there are no missing components, the material is loaded normally. If there are missing components, the waste will be processed into the waste trough, and an alarm will be issued after the waste trough is full. The waste in the waste trough is then cleaned manually, wherein the detection mechanism can use an intelligent camera or a multi-point detection switch, which can identify the height of any position in the area, thereby ensuring that no planetary gear 8 with missing components is assembled on the planetary frame 9.

[0039] Preferably, each of the mounting bases 2 is provided with a plurality of discharge troughs 20 for placing the lower gaskets 7 and the upper gaskets 6; specifically, in order to facilitate each loading, the present embodiment provides a plurality of discharge troughs 20 on each mounting base 2, and each of the discharge troughs 20 is used to place a plurality of upper gaskets 6 or lower gaskets 7 separately, and when the upper gaskets 6 or lower gaskets 7 in the discharge trough 20 are used up, they are manually replenished.

[0040] Since both the upper gasket 6 and the lower gasket 7 need to be placed as required during assembly, in an optional embodiment, the lower gasket 7 is placed in the corresponding discharge trough 20 in the same manner as when it is installed on the planetary carrier 9; the upper gasket 6 is placed in the corresponding discharge trough 20 in the same manner as when it is installed on the planetary gear 8, so the internal shape of the discharge trough 20 is adapted to the outer ring shape of the lower gasket 7 or the upper gasket 6 placed thereon, that is, the upper gasket 6 and the lower gasket 7 designed in this embodiment have the same structure and both have ears for anti-rotation limiting, that is, a section is extended from the edge of the outer ring of the gasket, and the extended part is bent at a certain angle away from the end of the gasket body (the specific extension length and bending angle are set according to actual conditions and are not described in detail here).

[0041] For ease of description and understanding, in the subsequent embodiments, the lower gasket 7 is used as an example for description, that is, the upper die set and the lower die set have the same structure. According to the above embodiments, due to the structural characteristics of the lower gasket 7, when multiple lower gaskets 7 are placed in the same discharge trough 20, the two adjacent lower gaskets 7 will not be completely fitted, and there is a certain angle of contact between the two. In this way, when the lower die set grabs the lower gasket 7, the lower gasket 7 is not corrected in position. In this way, when it is assembled on the planetary carrier 9, the lower gasket 7 will be placed in the wrong position. Therefore, in a further embodiment, a first combing mechanism is arranged in each discharge trough 20. Based on the combing effect of the first combing mechanism, multiple lower gaskets 7 are arranged axially apart in the corresponding discharge trough 20, that is, two adjacent gaskets are arranged separately, and the radial direction of each gasket is kept parallel to the radial direction of the corresponding discharge trough 20. In this way, the lower gasket 7 grabbed by the lower die set is also kept parallel to the horizontal plane in the radial direction, which can effectively reduce the situation of the lower gasket 7 being placed in the wrong position when placed on the planetary carrier 9.

[0042] Preferably, the first combing mechanism includes two belt drive mechanisms arranged along any radial direction in the discharge trough 20, and a plurality of combing spacers 21 are arranged in sequence along the conveying track on the conveyor belt of each belt drive mechanism. The plurality of combing spacers 21 on the two belt drive mechanisms correspond to each other one by one, and the space between two combing spacers 21 at adjacent positions along the conveying direction is used to place the lower gasket 7.

[0043] Specifically, each belt transmission mechanism includes a transmission belt and two pulleys. The specific working principle is the prior art and will not be repeated here. This embodiment is based on the belt transmission mechanism. A plurality of combing spacers 21 are arranged in sequence along the trajectory of the transmission belt. The plurality of combing spacers 21 on the two belt transmission mechanisms correspond to each other one by one. The space between two combing spacers 21 at adjacent positions along the conveying direction is used to place the lower gasket 7. The space is named as a discharge cavity. When placing a plurality of lower gaskets 7 in the discharge trough 20, along the depth direction of the discharge trough 20 (parallel to its own axial direction away from the opening end), after placing a lower gasket 7 in the discharge cavity at the top, it will move downward by a unit distance. The unit distance dimension is the thickness dimension of a lower gasket 7. At this time, another discharge cavity will be formed at the top. The lower gaskets 7 are placed in this way until no more can be placed. When the lower module grabs the lower gasket 7, it also grabs it from top to bottom in sequence.

[0044] As the number of lower gaskets 7 grabbed by the lower die increases, the depth of its extension into the discharge trough 20 also increases. Therefore, in an optional embodiment, a one-way transmission mechanism is also arranged on each belt transmission mechanism; when the lower gasket 7 is placed in the discharge trough 20, the one-way transmission mechanism releases the restriction on the belt transmission mechanism, that is, at this time, the two belt transmission mechanisms cooperate to extend and transport the lower gasket 7 to the discharge trough 20; when the lower die grabs the lower gasket 7 from the discharge trough 20, based on the restriction of the one-way transmission mechanism, the belt transmission mechanism transports the lower gasket 7 in the direction away from the discharge trough 20, that is, at this time, the lower die grabs the lower gasket 7 When the last lower gasket 7 needs to leave the discharge chute 20, the lower gasket 7 will drive the two belt transmission mechanisms to move. At this time, the two belt transmission mechanisms are equivalent to conveying the lower gasket 7 outward. However, after the lower module grabs the last lower gasket 7 and leaves the discharge chute 20, based on the gravity of the remaining lower gaskets 7 and the restriction of the one-way transmission mechanism, the two belt transmission mechanisms will not extend to the discharge chute 20 to convey the lower gasket 7. Among them, the one-way transmission mechanism is such as a ratchet pawl mechanism. When loading the lower gasket 7 into the discharge chute 20, it only needs to release the restriction of the pawl on the ratchet wheel. This is the prior art and will not be elaborated on in detail.

[0045] Preferably, the lower mold assembly includes a driving mechanism and a grabbing mechanism arranged at the power output end of the driving mechanism, the grabbing mechanism includes a grabbing arm 30, and two clamping blocks 31 are provided on the grabbing arm 30 along a radial sliding direction of the lower gasket 7. Based on the driving force of the driving mechanism, the two clamping blocks 31 clamp the inner circle of the lower gasket 7 in a manner away from each other.

[0046] Specifically, since the planetary carrier 9 involved has a flange structure at the bottom along the axial direction and a horizontally arranged plate structure at the top, holes for installing the rotating shafts of the planetary gears 8 are opened on it, and the flange structure is also correspondingly opened with holes corresponding to each rotating shaft, the plate structures on both sides of each planetary gear 8 installation position are connected to the flange structure through a vertically arranged plate structure, then when assembling the lower gasket 7 and the planetary gear 8, they can only enter and exit from the radial side. Therefore, in this embodiment, the driving mechanism needs to drive the grasping mechanism to move linearly in multiple directions, and also needs to drive the two clamping blocks 31 away from each other to clamp the lower gasket 7 from the inner ring. The driving mechanism can be composed of multiple driving sources that can realize linear movement, such as multiple cylinders arranged in multiple directions, and clamping the lower gasket 7 from the inner ring, so that the lower gasket 7 is installed at the corresponding position on the planetary carrier 9, and the outer ring is blocked when the lower gasket 7 is in it, and the use of inner ring and outer support clamping can better transport the lower gasket 7 into place.

[0047] Preferably, the two clamping blocks 31 are provided with clamping grooves 32 in contact with the clamped lower gasket 7, and the outer structure of the clamping grooves 32 matches the outer structure of the inner ring of the lower gasket 7; specifically, since the lower gasket 7 is relatively thin, it may rotate or fall when clamped by the two clamping blocks 31. Therefore, in the present embodiment, a clamping groove 32 is provided on each clamping block 31. In this way, when the two clamping blocks 31 clamp the lower gasket 7, the risk of the lower gasket 7 falling can be effectively solved because there is a height difference between the contact part of the clamping groove 32 and the inner ring of the lower gasket 7 and the rest of the clamping block 31. In addition, the outer structure of the clamping groove 32 is adapted to the outer structure of the inner ring of the lower gasket 7, so that it is difficult for the lower gasket 7 to rotate relative to the contact surface of the clamping groove 32, thereby better clamping each lower gasket 7.

[0048] Furthermore, each of the clamping blocks 31 is provided with a second combing mechanism, and the two clamping blocks 31 can grab a number of lower gaskets 7 corresponding to the number of lower gaskets 7 that need to be installed on each planetary carrier 9 at a time. Based on the combing effect of the second combing mechanism, the two lower gaskets 7 at adjacent positions are arranged at intervals.

[0049] The second combing mechanism includes a belt transmission mechanism arranged on each clamping block 31 (the same structure as the belt transmission mechanism in the aforementioned embodiment), and a plurality of material grabbing spacers 33 are arranged in sequence along the conveying track of the conveying belt of the belt transmission mechanism, and the distance between two material grabbing spacers 33 at adjacent positions is consistent with the thickness of a lower gasket 7. The plurality of material grabbing spacers 33 on the two clamping blocks 31 correspond to each other one by one, so that the two belt transmission mechanisms cooperate with each other, and the two clamping blocks 31 can clamp the number of lower gaskets 7 corresponding to the number of lower gaskets 7 that need to be installed on each planetary carrier 9 at a time. For example, each planetary carrier 9 requires four lower gaskets 7, and each of the two clamping blocks 31 Four or more than four lower gaskets 7 can be grabbed at a time, wherein a power wheel 34 is fixedly connected to a pulley of each belt transmission mechanism, and the two power wheels 34 are symmetrically arranged. A driving source for driving the two clamping blocks to move relative to each other is installed in the driving mechanism, and a first extrusion rod 35 is installed at the power output end of the driving source, and the first extrusion rod 35 is slidably arranged on the grabbing arm 30, and the grabbing arm 30 is slidably arranged on the power output end of the driving source in the driving mechanism area. A pressure surface 36 is provided on each clamping block 31, and a wedge-shaped fit is formed between the first extrusion rod 35 and each pressure surface 36 to form an extrusion action, and the two clamping blocks 31 An elastic member 37 is provided between the two clamping blocks 31. Based on the elastic force of the elastic member 37, the two clamping blocks 31 tend to always move away from each other, so as to expand outward to clamp the lower gasket 7. A guide groove 38 is provided on each clamping block 31. A guide block 39 is slidably provided in the guide groove 38. The guide block 39 is fixed to the clamping arm, thereby ensuring the stability of the relative movement of the two clamping blocks 31. When the first extrusion rod 35 squeezes the two pressure surfaces 36, the two clamping blocks 31 approach each other to remove the clamping of the lower gasket 7 at the bottom, and the lower gasket 7 falls into the specified position on the planetary carrier 9. In the process of the first extrusion rod 35 squeezing the two pressure surfaces 36 Since the elastic force of the elastic member 37 will hinder the first extrusion rod 35 from squeezing the two pressure surfaces 36, in the initial stage, after the first extrusion rod 35 contacts the two pressure surfaces 36, based on the elastic force of the elastic member 37, the first extrusion rod 35 will first drive the clamping arm to move and drive the two clamping blocks 31 to enter the planetary carrier 9. When the movement of the clamping arm is restricted, the first extrusion rod 35 continues to move and squeezes the two pressure surfaces 36. On the contrary, when the first extrusion rod 35 moves in a direction away from the two pressure surfaces 36, under the action of the rebound force of the elastic member 37, the first extrusion rod 35 first disengages from the two pressure surfaces 36, and then drives the clamping arm to withdraw from the planetary carrier 9.

[0050] The surface of each power wheel 34 is provided with a plurality of first slide grooves 340, a plurality of second slide grooves 341 and a third slide groove 342. The length direction of the first slide groove 340 is parallel to the axial direction of the power wheel 34. The second slide groove 341 is a columnar spiral structure on the surface of the power wheel 34. The plurality of first slide grooves 340 and the plurality of second slide grooves 341 are alternately arranged in the circumferential direction of the power wheel 34. The first extrusion rod 35 is provided with a second extrusion rod 343. The second extrusion rod 343 is an elastic telescopic structure and can slide in the first slide groove 340, the second slide groove 341 and the third slide groove 342. For ease of description and understanding, the direction in which the first extrusion rod 35 extrudes the pressure surface 36 is taken as a reference direction. Along this direction, the first slide groove 340 includes a end And b end, the second slide groove 341 includes c end and d end, and then one of the power wheels 34 is taken as an example. When the lowest lower gasket 7 needs to be placed at a specified position on the planetary frame 9, the power wheel 34 needs to rotate counterclockwise, that is, the b end of the first slide groove 340 is connected to the d end of the second slide groove 341 adjacent to the counterclockwise direction, and the a end of the first slide groove 340 is connected to the c end of the second slide groove 341 adjacent to the clockwise direction. When the first extrusion rod 35 squeezes the pressure surface 36, in the moving direction, the second extrusion rod 343 will directly enter the c end of the second slide groove 341 at the clockwise adjacent position from the a end of the first slide groove 340 (that is, the depth of the a end is the same as the depth of the c end, and the depth of the rest of the first slide groove 340 is less than The second extrusion rod 343 moves from the end b of the first slide groove 340 at the adjacent clockwise position to the end d of the second slide groove 341. During this process, the second extrusion rod 343 exerts an extrusion effect on the side wall of the second slide groove 341, causing the power wheel 34 to rotate once in the clockwise direction. Each rotation of the second extrusion rod 343 drives the belt transmission mechanism to move once, causing the lower gasket 7 at the lowest position to fall into the designated position of the planetary carrier 9. During the movement of the first extrusion rod 35 in the direction away from the pressure surface 36, the second extrusion rod 343 moves from the end b of the first slide groove 340 where it is located to the end a (that is, the depth of the end b is greater than the depth of the end d). In order to prevent the power wheel 34 from rotating when the first extrusion rod 35 squeezes the two pressure surfaces 36, at each The b end of the first slide groove 340 extends a section, that is, the first extrusion rod 35 drives the second extrusion rod 343 from the a end of the first slide groove 340 directly into the c end of the second slide groove 341 at the clockwise adjacent position, and then enters the b end of another first slide groove 340 at the clockwise adjacent position from the d end of the second slide groove 341, and then continues to move along the length direction of the first slide groove 340. At this time, the second extrusion rod 343 and the first slide groove 340 have no circumferential extrusion effect, so that the power wheel 34 will not rotate, and the first extrusion rod 35 squeezes the two pressure surfaces 36, so that the two clamping blocks 31 approach each other and drop the lower gasket 7 at the bottom into the specified position on the planetary frame 9. In order to prevent the remaining lower gaskets 7 from falling from their current positions,The maximum distance between the two corresponding grabbing spacers 33 of the two belt transmission mechanisms is still greater than the maximum distance between the clamped positions of the lower gasket 7. In order to facilitate the subsequent loading of the lower gasket 7 on the two clamping blocks 31, the present embodiment opens a third slide groove 342 at the a end of the first slide groove 340. The third slide groove 342 is an annular structure, and its depth is less than the depth of the first slide groove 340 (in the process of the second extrusion rod 343 sliding circumferentially along the third slide groove 342, each time it reaches a position where the first slide groove 340 is located, the first slide groove 340 will cause a certain obstacle to the continued movement of the second extrusion rod 343. In this way, this method can be used to measure the number of lower gaskets 7 loaded each time, and it can also avoid the rotation of the belt transmission mechanism due to the weight change of the loaded lower gasket 7). That is, when loading from the discharge trough 20, the two clamping blocks 31 will The two belt transmission mechanisms in the discharge trough 20 are restricted by the one-way transmission mechanism. In this way, when the two clamping blocks 31 enter the discharge trough 20, the two belt transmission mechanisms on the two clamping blocks 31 will be blocked by the lower gasket 7 and rotate, and each time a lower gasket 7 passes, it will rotate once. When the two clamping blocks 31 are pulled out of the discharge trough 20, the two belt transmission mechanisms in the discharge trough 20 can rotate under the action of external force, and the second squeeze rod 343 returns from the third slide 342 to the corresponding first slide 340 at this time. Then, the rotation of the power wheel 34 is restricted. When the two clamping blocks 31 bring out the lower gasket 7, the two belt transmission mechanisms in the discharge trough 20 are not restricted by the one-way rotation mechanism, and the lower gasket 7 can be loaded smoothly.

[0051] The advantages of such a configuration are: first, it can reduce the number of times the lower gasket 7 is loaded, thereby reducing the movement stroke of the clamping arm and improving the assembly efficiency of the lower gasket 7; second, the multiple loaded lower gaskets 7 are arranged separately, and the lowest lower gasket 7 is placed at a specified position on the planetary carrier 9 each time, and the remaining lower gaskets 7 will not fall, thereby avoiding affecting the assembly operation.

[0052] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the protection of the present invention.
