The guide block 2207 is L-shaped. The outer circumference of the needle roller clamping plate 2201 is provided with a step structure 2209, and the needle roller toggle plate 2203 is arranged on the step structure 2209. The inner side of the needle roller toggle plate 2203 has a groove 210 that matches the needle roller slot plate 201. A plurality of rotating rollers 211 are arranged in the groove 210. The upper end of the rotating roller 211 is connected to the needle roller toggle plate 2203, and the lower end is connected to the step structure 2209 of the needle roller slot plate 2201. The outer side of the needle roller toggle plate 2203 has a gear structure 2212, which is transmission-connected to the motor 2215. The motor 2215 drives the needle roller toggle plate 2203 to reciprocate through the gear structure 2212. The lower end of the needle roller core 2201 is connected to a locking flange 2213, and the needle roller slot plate 2202 is arranged on the locking flange 2213. The elastic baffle is connected to the lower end of the needle roller core through the locking flange and blocks the needle roller to prevent it from rolling and falling. An elastic baffle 2214 is also provided between the locking flange 2213 and the needle roller slot disk 2202, and the elastic baffle 2214 can block the pressed needle roller.

[0063] First, the guide groove 2204 of the needle roller slot plate 2202 and the needle roller guide tube 2205 are filled with needle rollers in advance, and the motor 2215 is started. The output gear of the motor 2215 is meshed with the gear structure 2212 on the outer side of the needle roller toggle plate 2203, and the needle roller toggle plate 2203 is synchronously driven to rotate. After the needle roller toggle plate 2203 rotates, the guide block 2207 moves forward along the opening groove 2206. After the guide block 2207 enters the guide groove 2204, the front end of the guide block 2207 pushes the guide The needle roller in the groove 2204 moves forward, and the needle roller at the inner end of the guide groove 2204 reaches the groove portion 2208, and the guide block 2207 blocks the needle roller in the needle roller guide tube 2205 from falling, and the motor 2215 stops rotating.

[0064] Take a gear assembly component to perform an internal gear assembly process as an example to illustrate (the same applies to the external gear component). First, the gear assembly component is moved to the bottom of the first gasket feeding mechanism through the turntable. At this position, due to the high vertical height of the outer ring cam, the depth of the gear assembly space is shallow. The first gasket feeding mechanism accurately feeds the lower copper gasket into the gear assembly space, completing the feeding of the lower copper gasket, which just corresponds to the sleeve positioning pin and is located on the upper end face of the assembly lower tooling; then, the turntable continues to rotate, and the gear assembly component moves to the second gasket feeding mechanism. The turntable rotates to the inspection station (not shown in the figure), and is inspected by the gasket inspection mechanism (the existing inspection mechanism of the gasket inspection mechanism is inspected by vision or other methods, which belongs to the prior art), and then rotates to the bottom of the gear feeding mechanism. At this position, the vertical height of the outer ring cam is higher than that of the previous station, and the depth of the gear assembly space is higher. Similarly, the gear just enters the gear assembly space and is correspondingly sleeved with the positioning pin; then rotates to the bottom of the needle roller feeding mechanism The needle roller feeding mechanism feeds multiple needle rollers into the gear assembly space, where the needle rollers are located between the locating pins and the inner ring of the gear. The gear assembly is then transferred to the needle roller inspection station (not shown in the figure), where it is inspected by the needle roller inspection mechanism (the needle roller inspection mechanism is an existing inspection mechanism that inspects by visual or other methods, and belongs to the prior art). The upper steel sheet and the upper copper sheet are then fed in sequentially through the third shim feeding mechanism and the fourth shim feeding mechanism, and the principle is the same as that of the first shim feeding mechanism and the second feeding mechanism; then the gear assembly enters the pin shaft feeding mechanism, and the pin shaft feeding mechanism The pin is sent into the gear assembly space, the pin is aligned with the positioning pin and partially enters the gear; the gear assembly assembly continues to rotate to the discharge station, where the outer ring cam has the highest vertical height. During the rotation, the lower assembly tool gradually rises, and the gear assembly is slowly pushed upward. At this time, the gear assembly moves upward relative to the pin, and the pin is fully inserted into the gear assembly to complete the assembly. Finally, the lower assembly tool completely pushes the gear assembly out of the turntable and supports it through the lower assembly tool. At this time, the assembly of the gear assembly is completed, and the assembled gear assembly can be stored. All gear assembly components complete the assembly of the gear assembly through the above steps, and automation can be realized to assemble the gear assembly in batches.

[0065] like Figures 19 to 24When the two groups of assembly devices complete the assembly of an inner gear component and an outer gear component respectively, the inner gear component and the outer gear component are sent to the gear merging mechanism 2. The gear merging conveying mechanism includes a gear transport component 401, on which a guide plate component 402 is installed, the guide plate component 402 forms a transport channel, and a transport seat 403 is installed on the gear transport component 401. The gear transport component 401 is provided with two separately arranged component entrances. The gear transport component 401 drives the transport seat 403 to move along the transport channel and pass through the two component entrances in sequence. Each component entrance sends a gear component to the same transport seat 403, and the gear component is rotatably connected to the transport seat 403 through its pin shaft. The guide plate component 402 has an inwardly closing guide surface 4026 at the component entrance. The gear component sent in first rotates and moves forward along the guide surface 4026 and moves along the transport channel, and the gear component sent in later rotates and moves forward along the guide surface 4026 and gradually approaches the gear component sent in first, so that the two gear components gradually mesh.

[0066] In addition, the component entrance includes an internal gear entrance 404 for feeding in the internal gear component 6 and an external gear entrance 405 for feeding in the external gear component 7. The guide plate assembly 402 includes side guide plates 4021 and gear guide plates arranged in parallel along both sides of the gear transport component. A transport channel is formed between the gear guide plate and the side guide plate 4021. The guide surface 4026 is located at the ends of the gear guide plate located at the internal gear entrance 404 and the external gear entrance 405. The transport seat 403 passes through the internal gear entrance, and the internal gear component 6 enters the transport seat 403. The transport seat 403 moves forward so that the internal gear component 6 enters the transport channel along the guide surface 4026. The transport seat 403 passes through the external gear entrance 405, and the external gear component 7 enters the transport seat 403. The transport seat 403 moves forward so that the external gear component 7 enters the transport channel along the guide surface 4026 and gradually approaches the internal gear component 6, so that the internal gear component 6 and the external gear component 7 gradually mesh and are sent out through the outlet 408 at the end of the gear transport channel. The inner gear assembly 6 and the outer gear assembly 7 are pushed into the transport seat by an external manipulator or a pushing device, and the manipulator or the pushing device here can be selected according to the conventional means or common knowledge in the art. The inner gear assembly 6 and the outer gear assembly 7 both include gears, gaskets are provided at the upper and lower ends of the gears, a pin shaft is passed through the inside of the gear, and a needle roller is provided between the pin shaft and the inside of the gear.

[0067] In addition, the gear guide plate includes a front guide plate 4022 and a rear guide plate 4023. The left end of the front guide plate 4022 is close to the inner gear entrance 404, and the right end is close to the outer gear entrance 405. The left end of the rear guide plate 4023 is close to the outer gear entrance 405, and the right end is located at the exit 408 of the gear transport assembly 401. The guide surface is located at the inner gear entrance and the right end of the outer gear assembly.

[0068] In addition, the width of the front guide plate 4022 is greater than that of the rear guide plate 4023. The transport channel includes an inner gear channel 4024 formed by the front guide plate 4022 and the side guide plate 4021 and a confluence channel 4025 formed by the rear guide plate 4023 and the side guide plate 4021. The width of the inner gear channel 4024 is slightly greater than the outer diameter of the inner gear assembly 6, and the width of the confluence channel 4025 is slightly greater than the sum of the outer diameters of the meshed inner gear assembly 6 and the outer gear assembly 7. The movement direction of the inner gear assembly 6 and the outer gear assembly 7 is limited by the size of the transport channel. Most importantly, it can ensure that the inner gear assembly and the outer gear assembly do not generate relative displacement during the transport process, which may cause deviations during the subsequent installation process.

[0069] In addition, the inner gear inlet 404 is located at the left end of the gear transport assembly 401 , and the outer gear inlet 405 is located in the middle of the gear transport assembly 401 .

[0070] In addition, the side guide plates 4021 and the gear guide plates are installed on the left and right sides of the gear transport assembly 1, and the transport seat 403 is located below the side guide plates 4021 and the gear guide plates.

[0071] In addition, the transport seat 403 and the component entrance have a step-like structure 4031 that is symmetrically arranged on the left and right sides, and a positioning groove 4032 is formed between the bottoms of the step-like structure 4031. The pins of the inner gear assembly 6 and the outer gear assembly 7 are rotatably arranged in the positioning groove 4032. The inner gear assembly 6 and the outer gear assembly 7 are respectively moved to the positioning groove 4032 of the transport seat 403 through the corresponding positioning grooves 4032 on the component entrance, ensuring that the positions of the inner gear assembly 6 and the outer gear assembly 7 entering the transport seat 3 are not offset.

[0072] In addition, the gear transport assembly 401 includes a base 4011 , a double-row sprocket chain device 4012 is horizontally installed on the upper edge of the base 4011 , and the transport seats 403 are evenly spaced and arranged on the double-row sprocket chain device 4012 .

[0073] The gear transport assembly 401 is started, and the transport seat 403 begins to move. When the transport seat 403 moves to the internal gear entrance 404, an internal gear assembly 6 is sent into the transport seat 403 through the internal gear entrance 404, and the transport seat 403 continues to move forward. During the forward movement of the transport seat 403, the guide surface 4026 at the end of the front guide plate 4022 contacts the internal gear assembly 6, and the internal gear assembly 6 slowly rotates along the guide surface 4026 and moves forward with the transport seat 403 to the internal gear channel 4024. The transport seat 403 drives the internal gear assembly 6 to move forward along the internal gear channel 4024. When the transport seat 403 continues to move to the external gear entrance 405, an external gear assembly 7 is sent into the transport seat 403 through the external gear entrance 405. The transport seat 403 continues to move forward. During the forward movement of the transport seat 403, the guide surface 4026 of the rear guide plate 4023 contacts the outer gear assembly 7. The outer gear assembly 7 slowly rotates along the guide surface 4026 and moves forward with the transport seat 403. During the movement, the outer gear assembly 7 gradually moves downward toward the inner gear assembly 6, so that the outer gear assembly 7 gradually meshes with the inner gear assembly 6. The transport seat 403 continues to move forward. After the outer gear assembly 7 is fully meshed with the inner gear assembly 6, it enters the confluence channel 4025 and moves along the confluence channel 4025 to the outlet 408 at the end of the gear transport assembly 401 for transport. After that, the outer gear assembly 7 meshes with the inner gear assembly 6 to form a gear set 36 and then enters the planetary carrier gear mounting device.

[0074] like Figure 26 to Figure 32, a planetary carrier gear mounting device includes a gear mounting turntable mechanism 31 and a planetary carrier gear mounting mechanism 32 (in order to clearly describe the positional relationship between the gear mounting turntable mechanism 31 and the planetary carrier gear mounting mechanism 32, the specific structure of the planetary carrier gear mounting mechanism installed on other work surfaces is not drawn in the drawings of the present application); the gear mounting turntable mechanism 31 includes a work surface 311, a cam divider 312 driven by a motor is provided at the bottom of the work surface 311, a turntable assembly 33 is provided above the work surface 11, the turntable assembly 33 is connected to the cam divider 312 and is driven to rotate by the cam divider 312, the turntable assembly 33 includes a rotating table 331, a plurality of gear set transfer components 332 are provided on the rotating table 331 around the center thereof, a gear set feeding component 333 is provided on the work surface 1, the gear set transfer component 332 cooperates with the gear set feeding component 333 to feed the gears into the work surface 1 through the gear set feeding component 333 The planetary carrier 37 is connected to the gear set 36 by the planetary carrier gear installation mechanism 32 and the gear set transfer component 332. The planetary carrier gear installation device also includes a pin replacement assembly 34 arranged at the gear installation position of the planetary carrier gear installation mechanism 32 and the gear set transfer component 332. The pin replacement assembly 34 includes an upper ejector pin component 341 and a lower ejector pin component 342. The upper ejector pin component 341 is provided with a replacement pin 343. Before the planetary carrier 37 is assembled with the gear set 36, the replacement pin 343 is pressed into the gear set 36 by the upper ejector pin component 341, and the pin shaft 361 in the gear set 36 is pushed into the lower ejector pin component 342. After the planetary carrier 37 is assembled with the gear set 36, the lower ejector pin component 342 pushes the pin shaft 361 upward into the gear set 36, and pushes the replacement pin 343 out of the gear set 36, so that the gear set 36 is connected and assembled with the planetary carrier 37.

[0075] In addition, the upper ejector pin component 341 includes an upper cylinder 344, and the replacement pin 343 is sleeved on the ejector rod of the upper cylinder 344. The upper cylinder 344 pushes the replacement pin 343 downward to enter the gear set 36. The replacement pin 343 ejects the pin shaft 361 in the gear set 36 and forms an interference fit with the roller needle 362 in the gear set 36. The upper cylinder 344 moves upward to separate the replacement pin 343 from the ejector rod. The lower ejector pin component includes a lower cylinder 345. The pin shaft 361 is sleeved on the ejector rod of the lower cylinder 345 after being ejected from the gear set 36 by the replacement pin 343. After the planet carrier 37 and the gear set 36 are assembled, the lower cylinder 344 pushes the pin shaft 361 upward to eject the replacement pin 343 from the gear set 36 and cooperates with the roller needle 362 in the gear set 36. The lower cylinder 345 moves downward to separate the pin shaft 361 from the ejector rod. The length of the replacement pin 343 is smaller than the length of the pin shaft 361 , so that the gear set 36 can be smoothly installed in the planetary carrier. After being installed in the planetary carrier 37 , the replacement pin 343 is ejected through the pin shaft 361 .

[0076] In addition, the gear set transfer component 332 includes a fixed frame 321 embedded on the rotating table 331, and a sliding sleeve 3322 is movably connected to the fixed frame 332. The front end of the sliding sleeve 3322 has an installation cavity 323 for setting the gear set, and the upper and lower end surfaces of the installation cavity 3323 have positioning holes 3324 that cooperate with the pin 361 of the gear set 36. The gear set 36 is pushed into the installation cavity 3323 through the gear set feeding component 333 so that the pin 361 cooperates and is engaged in the positioning hole 3324. The front end of the sliding sleeve 3322 also has an inclined push surface 3325 that cooperates with the planetary carrier 37. The planetary carrier 37 is pushed by the planetary carrier gear mounting mechanism 32, so that the planetary carrier 37 contacts the inclined push surface 3325 and pushes the sliding sleeve 3322 backward, thereby connecting and assembling the planetary carrier 37 and the gear set 36.

[0077] In addition, the rear end of the sliding sleeve 3322 is connected to the fixing frame 3321 via a spring 3326 . A guide column 3327 is further provided in the fixing frame 3321 , and the sliding sleeve 3322 is slidably connected to the guide column 3327 .

A pushing cylinder 3333 is also installed on the feeding plate 3331, and a pushing plate 3334 is connected to the pushing cylinder 3333. The pushing plate 3334 cooperates with the gear group 36 to push the gear group 36 into the installation cavity 3322 of the sliding sleeve 3322 along the feeding trough 3332. The lower end of the rotating shaft 361 is rotatably connected in the feeding trough 3332 to ensure that the meshing degree of the gear group 36 will not deviate during the forward movement. Figure 6 The feed plate on the middle right is a schematic diagram showing the position of the gear set 36 when it is delivered to the gear set transfer component 332. The gear set is omitted in this position.

[0079] In addition, a baffle 313 is provided on the work surface 311, and the baffle 313 is arranged along the outer side of the rotating table 331, and one end of the baffle 311 is located on one side of the feed plate 3331, and the other end extends to the assembly position of the planet carrier 37 and the gear set 36. The baffle 313 can prevent the gear set 36 from falling from the gear set transfer component 332 when the gear set 36 rotates with the turntable assembly 33.

[0080] In addition, the planetary carrier gear mounting mechanism 32 includes a ball screw slide assembly 321, which is connected to a first hollow rotating platform 322, and a bracket 323 is connected to the inner ring of the first hollow rotating platform 322. An ejection cylinder 324 is provided inside the bracket 323, and a support plate 325 for placing the planetary carrier is installed above the bracket 323.

The planetary carrier 37 is connected to the support plate 325 and is partially engaged and clamped between the hollow connecting sleeve 326 and the drawing sleeve 327. The ejection cylinder 324 pushes the drawing sleeve 327 to lift or lower so that the drawing sleeve 32 clamps or releases the planetary carrier 337, and the first hollow rotating platform 322 drives the bracket to rotate to rotate the planetary carrier 37.

[0081] In addition, the upper ends of the drawing sleeve 327 and the hollow connecting sleeve 326 are provided with elastic clamping pieces 328 arranged at even intervals. The ball screw slide assembly 321 is also provided with a planet carrier elastic limiting pad assembly 329 to press the planet carrier to prevent the planet carrier from falling.

[0082] In addition, the planet carrier gear mechanism 32 is connected to the main hollow rotating platform 35 , and the main hollow rotating platform 35 drives the planet carrier gear mechanism 32 to rotate. The planet carrier gear mechanism 32 is connected to the inner ring of the main hollow rotating platform 35 to rotate.

[0083] The meshed gear set 36 is sent into the gear set feeding component 333, and the pushing cylinder 3333 drives the pushing plate 3334 to make the gear set 36 move along the feeding trough 3332. Any gear set transfer component 332 on the turntable assembly 33 is opposite to the feeding trough 3332. At this time, the gear set 36 enters the installation cavity 3323 of the sliding sleeve 3332, and the two ends of the pin shaft 361 are limited by the positioning holes 3324. After the gear set 36 is assembled in place, the cam divider 312 drives the rotating table 331 of the turntable assembly 33 to rotate, and the other gear set transfer component 332 moves to the position of the gear set feeding component 333 to continue to assemble the gear set 36, and the gear set transfer component 332 of the assembled gear set 36 rotates forward until it rotates to the position corresponding to the planetary carrier gear mounting mechanism 32. At this time, the upper cylinder 344 is started, and the upper cylinder 344 drives the replacement pin 343 downward, and the replacement pin 343 faces the pin shaft 361 of the gear set 36, and the pin shaft 361 of the gear set 36 is ejected from the gear set 36. The ejected pin shaft 361 is engaged with the lower cylinder 345 located below the pin shaft 361. Then the ball screw slide assembly 321 of the planetary carrier gear mechanism 32 is started, and the bracket 323 with the planetary carrier 37 installed in advance moves forward until the outer ring of the planetary carrier 37 and the sliding sleeve 3 The front end inclined push surface 3325 of 322 contacts and starts to push the sliding sleeve 3322 backward. As the planetary carrier 37 moves forward, the gear set 36 gradually enters the installation position in the planetary carrier 37 until the planetary carrier 37 moves forward to the position. At this time, the planetary carrier 37 and the gear set 36 are fully aligned. Then the lower cylinder 345 is started, and the lower cylinder 345 pushes the pin 361 upward. The pin 361 pushes the replacement pin 343 out of the gear set 36 again. After the replacement pin 343 is pushed out, it is still in contact with the upper cylinder 34 4 connection, at this time, the installation of a set of gear sets is completed, and then the ball screw slide assembly 321 retreats, the planetary carrier 37 is separated from the sliding sleeve 3322, the sliding sleeve 3322 is reset, and the turntable assembly 33 continues to rotate, and the next gear group transfer component 332 installed with the gear group 36 moves into place, and then the first hollow rotating platform 322 is started, and the planetary carrier 37 rotates with the bracket 323, and another installation position on the planetary carrier 37 where a gear group needs to be installed is opposite to the gear group 36, and then the above process is repeated, and the gear group 36 is installed again until all the gear groups on one planetary carrier are assembled in place, and finally the main hollow rotating platform rotates to send the installed planetary row to the next station, and then the oil guide plate is riveted and various inspections are carried out (the various inspection devices are conventional visual inspections, pneumatic inspections and other inspection devices), and the qualified planetary row is sent out.
