Description

Technical Field

[0001] This invention relates to the technical field of automated equipment, and in particular to an automatic installation device for pins used in powder metallurgy gear parts. Background Technology

[0002] Planetary pins are one of the main components of planetary gear trains. They are vertically mounted on the planetary gears, while other gear shafts or bearings are rotatably mounted on them. Currently, conventional planetary gears are mass-produced using powder metallurgy, while planetary pins are specifically made of stainless steel or bearing steel. Due to the differences in materials and forming conditions between planetary gears and planetary pins, they are generally formed separately in production, and the planetary pins are then machined to attach to the planetary gears. For example, one existing assembly used in planetary gear trains... (Refer to...) Figure 1 The assembly includes a gear and several pins. The gear has several sets of insertion holes, and the pins are all vertically inserted into the insertion holes of the gear.

[0003] In existing machining techniques, planetary pin installation is typically achieved using a pin presser. As the name suggests, a pin presser inserts the pin into the gear's insertion hole by pressing it down. Specifically, the operator first places the pre-formed gear directly under the pressing mechanism of the pin presser, then positions the pin corresponding to the gear's insertion hole. Finally, as the pressing mechanism presses down, the planetary pin is fully inserted into the gear, thus completing the installation.

[0004] Although pin-pressing machines are widely used in planetary gear machining, their automation level remains low. Operations such as loading and unloading gear parts or pins, and positioning and installing pins, still require manual operation, significantly increasing the workload for workers. Furthermore, because workers need to manually support the pins to ensure they remain perpendicular to the gear part during pressing, the machine can only install one pin at a time. This not only results in low installation efficiency but also poses significant safety hazards for workers. Summary of the Invention

[0005] To improve the installation efficiency of pins on planetary gears, simplify manual operation procedures, and enhance safety, this application provides an automatic pin installation device for powder metallurgy gear parts.

[0006] The automatic pin installation device for powder metallurgy gear parts provided in this application adopts the following technical solution:

[0007] An automatic pin installation device for powder metallurgy gear parts includes a frame, and a gear feeding mechanism, a detection mechanism, an assembly mechanism and a claw moving mechanism sequentially installed on the frame;

[0008] The frame is provided with a discharge port for discharging material;

[0009] The feeding mechanism includes a first vibratory plate for feeding gear parts. The discharge end of the first vibratory plate is connected to a feeding module. The feeding module connects the first vibratory plate and the detection mechanism and is used to sequentially transport gear parts from the first vibratory plate to the detection mechanism.

[0010] The testing mechanism includes a testing platform, a testing module, and a calibration module. The discharge end of the feeding module is connected to the testing platform. The testing module is located on the side close to the testing platform and is used to test the placement position and angle of the gear components on the testing platform. The calibration module is used to move the gear components to the next process and to correct the placement position and angle of the gear components during the movement.

[0011] The assembly mechanism includes a pressing platform module, a pin feeding module, and an installation module. The pressing platform module includes an installation platform for placing gear components. The pin feeding module is used to feed pins to the installation platform. The installation module is mounted directly above the installation platform and is used to press and install the gear components and pins on the installation platform.

[0012] The moving claw mechanism includes a moving module and a gripper module. The moving module is used to drive the gripper module to slide and move up and down. The gripper module is used to hold the gear component and cooperates with the moving module to enable the gear component to move in the assembly mechanism.

[0013] By adopting the above technical solution and through the cooperation of the above multiple mechanisms, only a single installation device is needed to complete the feeding and installation process of gear parts and pins, as well as the unloading process of the assembly. The entire process does not require operation or support from staff, which greatly simplifies the preparation process of the assembly, improves the installation efficiency of pins, and reduces the labor intensity of staff.

[0014] Optionally, the feeding module includes a feeding channel and a feeding drive. The feeding channel connects the first vibratory plate and the detection table, and the feeding channel extends downward at an angle toward the detection table. The width of the feeding channel is equal to the width of the gear component, and feeding baffles are provided at the top of both sides of the feeding channel. The feeding drive is used to drive the feeding channel to vibrate.

[0015] By adopting the above technical solution, since the width of the feeding channel is equal to the width of the gear components, the gear components can enter the feeding channel one by one and be arranged in a row, which is beneficial for the subsequent testing mechanism to inspect the gear components one by one. At the same time, since the feeding drive component moves the gear components by vibrating the feeding channel, the feeding baffles set on both sides of the feeding channel can effectively prevent the gear components from being shaken out of the feeding channel, which helps to ensure the conveying stability of the gear components.

[0016] Optionally, the detection module includes a detection bracket, a detection probe, and an adjustable lens. The detection bracket holds the detection probe and the adjustable lens directly above the detection stage, and the adjustable lens is slidably disposed between the detection probe and the detection stage.

[0017] By adopting the above technical solution, the detection focal length of the detection probe can be adjusted by sliding and adjusting the distance between the adjustable lens and the detection probe, which helps to improve the detection accuracy of the detection probe.

[0018] Optionally, the calibration module includes a calibration slide, a calibration arm, a calibration lifting member, and a calibration assembly. The calibration arm is mounted on the calibration slide, and the calibration lifting member is located at one end of the calibration arm near the detection table. The calibration assembly includes a calibration seat, which is mounted on the lifting end of the calibration lifting member. The calibration seat is provided with a calibration claw and a calibration drive member. The calibration claw is rotatably connected to the calibration seat, and the drive end of the calibration drive member is connected to the calibration claw via a belt drive. The calibration drive member is electrically connected to the detection module.

[0019] By adopting the above technical solution, the calibration claw can move the gear on the inspection table to the next process through the drive of the calibration slide and the calibration lifting component. Moreover, during the movement of the calibration claw, the calibration drive component can also drive the calibration claw to rotate according to the inspection status of the inspection module, and rotate to adjust the placement position and angle of the gear, which is beneficial to ensure that the pin can be accurately inserted into the insertion hole of the gear during subsequent installation, thus improving the installation yield.

[0020] Optionally, the pin feeding module includes a second vibratory plate, a pin feeding guide, a pin feeding platform, and a pin feeding drive. The pin feeding platform has several sets of pin positioning holes. The pin feeding guide connects the second vibratory plate and the pin positioning holes of the pin feeding platform. The mounting platform is provided with a mounting plate, and the mounting plate has pin fixing holes. The pin fixing holes correspond to the pin positioning holes. The pin feeding drive is used to drive the pin feeding platform to slide back and forth toward the mounting plate.

[0021] By adopting the above technical solution, the pins are fed through the second vibratory feeder and guided into the pin positioning holes of the pin feeding table through the pin feeding guide. When the pin feeding drive pushes the pin feeding table towards the mounting plate, the pins slide together with the pin feeding table in the pin positioning holes. When the pin positioning holes of the pin feeding table are aligned with the pin fixing holes on the mounting plate, the pins in the pin positioning holes fall directly into the pin fixing holes on the mounting plate. Then, the pin feeding drive can drive the pin feeding table to slide back. At this time, the required pins are placed in the mounting plate of the mounting table. The mounting plate not only positions the pins for accurate subsequent installation but also supports them, eliminating the need for additional operations by workers and reducing their labor intensity.

[0022] Optionally, the second vibratory feeder is provided with a distributor, and the distributor has a guide groove inside. The guide groove is wide at the beginning and narrow at the end from the inlet to the outlet. The feeding pin guide is connected to the outlet of the distributor.

[0023] By adopting the above technical solution, since the guide groove in the distributor is wide at the beginning and narrow at the end, the pin on the second vibrating plate can enter the distributor more easily. Moreover, the guide groove in the distributor can also guide the pin, which is conducive to the pin entering the pin feeding guide smoothly.

[0024] Optionally, the mounting module includes a mounting bracket, a pressing component, and an pushing component. The pressing component includes a pressing drive and a stripping rod. The mounting bracket holds the pressing drive directly above the mounting plate. The pressing drive is used to drive the stripping rod to reciprocate toward the mounting plate.

[0025] The push-up assembly is disposed on the bottom side of the mounting platform. The push-up assembly includes a push-up drive, a push-up rod, and a push-up plate. The push-up rod connects the push-up drive and the push-up plate. The push-up drive drives the push-up plate to reciprocate toward the mounting plate via the push-up rod.

[0026] By adopting the above technical solution, when it is necessary to install gear parts and pins, the pressing drive and the pushing drive are activated simultaneously. The pressing drive presses the gear parts down through the stripping rod, while the pushing drive pushes the pins up through the pushing rod and the pushing plate. The pressing and pushing components cooperate with each other, which can effectively ensure that the pins can be fully inserted into the insertion holes of the gear parts, thus improving the installation yield.

[0027] Optionally, a space is reserved between the push plate and the mounting plate, and the distance from the top side of the push plate to the top side of the mounting plate is the same as the length of a single pin.

[0028] By adopting the above technical solution, when the pin of the pin feeding platform falls into the pin fixing hole of the mounting plate, the top of the pin is just level with the top side of the mounting plate due to the support of the push plate and the support of the mounting plate. At this time, the junction of the pin and the next pin is just level with the junction of the pin feeding platform and the mounting platform, so as not to interfere with the sliding of the pin feeding platform, which helps to ensure the smooth operation of the pin feeding module.

[0029] Optionally, the pressing platform module further includes a transfer platform and a discharge platform, the transfer platform and the discharge platform are respectively disposed on both sides of the mounting platform, the discharge port is located on the side of the discharge platform away from the mounting platform, and the transfer platform, the mounting platform, the discharge platform and the discharge port are distributed at equal intervals.

[0030] The gripper module includes a gripper arm, which is disposed on the moving module. The gripper arm is provided with a first gripper, a second gripper, and a third gripper in sequence. The first gripper, the second gripper, and the third gripper correspond to the transfer platform, the mounting platform, and the discharge platform, respectively.

[0031] By adopting the above technical solution, since the transfer platform, mounting platform, discharge platform, and discharge port are equally spaced, when the moving module drives the gripper arm to slide, the first gripper can reciprocate between the transfer platform and the mounting platform, the second gripper can reciprocate between the mounting platform and the discharge platform, and the third gripper can reciprocate between the discharge platform and the discharge port. Thus, the gripper module can simultaneously complete three moving actions: moving the gear component from the transfer platform to the mounting platform, moving the gear component from the mounting platform to the discharge platform, and moving the gear component from the discharge platform to the discharge port. This greatly improves the moving efficiency of the gripper mechanism and allows the installation process of the gear component and pin to be carried out continuously like an assembly line, which is conducive to improving the installation efficiency of the installation equipment.

[0032] Optionally, the first gripper, the second gripper, and the third gripper can be any one of a flexible gripper cylinder or an electromagnetic chuck.

[0033] By adopting the above technical solutions, when the first, second, and third grippers are made of flexible gripper cylinders, the physical clamping force on the gear components can be precisely controlled. Since most gear components are made of powder metallurgy, this helps to reduce the adverse effects of clamping on the gear components. Furthermore, when the first, second, and third grippers are made of electromagnetic chucks, the gear components can be picked up and lowered simply through electrical control, without causing any adverse effects such as clamping damage, thus protecting the gear components.

[0034] In summary, the technical solution of this application has at least one of the following beneficial effects:

[0035] 1. Through the cooperation of the feeding mechanism, the testing mechanism, the assembly mechanism and the moving claw mechanism, only a single installation device is needed to automatically complete the feeding and installation process of gear parts and pins, as well as the unloading process of the assembly. The entire process does not require operation or support from personnel, which greatly simplifies the preparation process of the assembly, helps to improve the installation efficiency of pins and reduce the labor intensity of personnel.

[0058] The following is in conjunction with the appendix Figure 1-15This application will be described in further detail.

[0059] An assembly 1 applied to planetary gear transmission, as shown in the reference. Figure 1 The assembly 1 includes a gear 11 and a pin 12, wherein the gear 11 has four insertion holes 111, and the pin 12 is vertically inserted into the insertion holes 111 of the gear 11.

[0060] This application discloses an automatic pin installation device for powder metallurgy gear parts. (Refer to...) Figure 2 and Figure 3 An automatic pin installation device for powder metallurgy gear parts includes a frame 2, and a feeding mechanism 3, a detection mechanism 4, an assembly mechanism 5, and a moving claw mechanism 6 mounted on the frame 2. The feeding mechanism 3 sequentially conveys gear parts 11 to the detection mechanism 4. The detection mechanism 4 detects and corrects the placement position and angle of the gear parts 11, and conveys the gear parts 11 to the assembly mechanism 5 with the correct placement position and angle. The assembly mechanism 5 includes a pressure table module 51, a pin feeding module 52, and an installation module 53. The pin feeding module 52... The machine can transport the required pins 12 to the pressing module 51, and the gear parts 11 that have been inspected and corrected by the detection mechanism 4 are also transported to the pressing module 51. The installation module 53 is used to press and install the gear parts 11 and pins 12 on the pressing module 51, resulting in the assembled assembly 1. The frame 2 has a discharge port 21, and the moving claw mechanism 6 is used to move the gear parts 11 in the assembly mechanism 5 and can move the assembled assembly 1 from the assembly mechanism 5 to the discharge port 21, thereby realizing the discharge of the assembly 1. Through the cooperation of the above multiple mechanisms, only a single installation device is needed to complete the feeding, installation, and discharge process of the gear parts 11 and pins 12, as well as the assembly 1. The entire process does not require operation or support from personnel, which greatly simplifies the preparation process of the assembly 1, improves the installation efficiency of pins 12, and reduces the labor intensity of personnel.

[0061] Reference Figure 3 and Figure 4 The feeding mechanism 3 includes a first vibratory feeder 31 and a feeding module 32. The first vibratory feeder 31 stores and provides gear components 11. The feeding module 32 connects the first vibratory feeder 31 and the detection mechanism 4, and is used to transport the gear components 11. The feeding module 32 includes a feeding channel 321 and a feeding drive 322. One end of the feeding channel 321 is connected to the discharge end of the first vibratory feeder 31, and the other end extends downwards at an angle and connects to the detection mechanism 4. The feeding drive 322 is located on the bottom side of the feeding channel 321. Specifically, the feeding drive 322 can be a drive device capable of vibrating the feeding channel 321, thereby allowing the gear components 11 to slowly move along the feeding channel 321 towards the detection mechanism 4 through vibration. In this embodiment, the feeding drive 322 is specifically a vibratory motor.

[0062] Reference Figure 4 Furthermore, the inner width of the feeding channel 321 is the same as the maximum width of the gear component 11, so that the gear components 11 can enter the feeding channel 321 one by one and be arranged in a row. At the same time, feeding baffles are provided at the top of both sides of the feeding channel 321 to prevent the gear components 11 from being shaken out of the feeding channel 321.

[0063] Reference Figure 3 and Figure 5 The testing mechanism 4 includes a testing table 41, a testing module 42, and a calibration module 43. The discharge end of the feeding channel 321 is connected to the testing table 41. The testing table 41 is used to place a single gear component 11 for testing. The testing module 42 is used to test the placement position and angle of the gear component 11. The calibration module 43 is used to move the gear component 11 to the next process and can correct the placement position and angle of the gear component 11 during the movement to ensure that the gear component 11 can maintain the correct placement position and angle in the assembly mechanism 5, thereby helping to reduce the installation error of the pin 12.

[0064] Reference Figure 5 The detection module 42 includes a detection bracket 421, a detection probe 422, and an adjustable lens 423. The detection bracket 421 is mounted on one side of the detection table 41. The detection probe 422 is fixedly mounted on the detection bracket 421 and is positioned directly above the detection table 41 via the detection bracket 421. The adjustable lens 423 is slidably mounted on the detection bracket 421 and located between the detection probe 422 and the detection table 41. The adjustable lens 423 can be slidably adjusted to change the detection focal length of the detection probe 422 to ensure the detection accuracy of the detection probe 422.

[0065] Reference Figure 5 The calibration module 43 includes a calibration slide 431, a calibration arm 432, a calibration lifting member 433, and a calibration assembly 434. The calibration arm 432 is mounted on the calibration slide 431, which drives the calibration arm 432 to slide longitudinally and laterally. In this embodiment, the calibration slide 431 is specifically a cross slide. The calibration lifting member 433 is located at the end of the calibration arm 432 facing the detection table 41. The calibration assembly 434 is located at the lifting end of the calibration lifting member 433, and the calibration assembly 434 can be raised and lowered by the drive of the calibration lifting member 433. Specifically, in this embodiment, the calibration lifting member 433 is a slide cylinder.

[0066] Reference Figure 5 and Figure 6The calibration assembly 434 includes a calibration seat 4341, a calibration claw 4342, and a calibration drive 4343. The calibration seat 4341 is fixedly mounted on the drive end of the calibration lifting component 433. Both the calibration claw 4342 and the calibration drive 4343 are mounted on the calibration seat 4341. The calibration claw 4342 is rotatably disposed within the calibration seat 4341. The drive end of the calibration drive 4343 is connected to the calibration claw 4342 via a belt drive, and the calibration drive 4343 drives the calibration claw 4342 to rotate. Furthermore, the calibration drive 4343 is electrically connected to the detection probe 422, so that the calibration drive 4343 can drive the calibration claw 4342 to rotate according to the placement position and angle of the gear component 11 based on the detection results of the detection probe 422, thereby achieving precise calibration and adjustment of the gear component 11. Specifically, in this embodiment, the correction claw 4342 is an electromagnetic chuck. The correction claw 4342 uses electromagnetic adsorption to grasp and release the gear component 11. In other embodiments, the correction claw 4342 can also be a flexible gripper cylinder, thereby reducing the adverse effects on the gear component 11 made of powder metallurgy.

[0067] Reference Figure 7 and Figure 8 Furthermore, a correction positioning element 43421 is also provided at the bottom of the correction claw 4342. The correction positioning element 43421 specifically corresponds to the insertion hole 111 on the gear component 11. When the correction claw 4342 attracts or clamps the gear component 11, the correction positioning element 43421 is inserted into the insertion hole 111 of the gear component 11. In addition, the correction drive element 4343 can be a drive device that can precisely drive the correction claw 4342 to rotate. In this embodiment, the correction drive element 4343 is specifically a servo motor.

[0068] Reference Figure 2 , Figure 3 and Figure 9 The pressing module 51 includes a transfer platform 511, a mounting platform 512, and a discharge platform 513. The transfer platform 511 and the discharge platform 513 are respectively located on both sides of the mounting platform 512, and the discharge port 21 is located on the side of the discharge platform 513 away from the mounting platform 512. The transfer platform 511, the mounting platform 512, the discharge platform 513, and the discharge port 21 are evenly spaced. The transfer platform 511, the mounting platform 512, and the discharge platform 513 are used to place the gear component 11 to be installed, the gear component 11 being installed, and the assembled component 1 that has been installed, respectively. Specifically, the calibration module 43 moves the gear assembly from the testing platform 41 to the preparation platform, while the gear component 11 located on the transfer platform 511 can be moved sequentially to the mounting platform 512, the discharge platform 513, and the discharge port 21 by the pawl mechanism 6, thus completing the installation process of the gear component 11 and the pin 12 and the discharge process of the assembled component 1 in sequence.

[0069] Reference Figure 9 , Figure 10 and Figure 11 The pin feeding module 52 includes a second vibratory feeder 521, several pin feeding guides 522, a pin feeding platform 523, and a pin feeding drive 524. The second vibratory feeder 521 is located on one side of the mounting platform 512 and is used to store and supply pins 12. One end of the pin feeding guide 522 is connected to the discharge end of the second vibratory feeder 521, and the other end extends downward and is connected to the pin feeding platform 523. Thus, the pins 12 can be conveyed to the pin feeding platform 523 by gravity along the pin feeding guide 522, and the pin feeding platform 523 can further convey the pins 12 to the mounting platform 512 through the pin feeding drive 524. Specifically, in order to make it easier for the pin 12 to enter the pin feeding guide 522 under the vibration of the second vibrating plate 521, a diverter 5211 is also provided at the discharge end of the second vibrating plate 521. The pin 12 guide is connected to the discharge end of the diverter 5211. A guide groove 52111 is provided on the inner side of the diverter 52111. The guide groove 52111 is wide at the beginning and narrow at the end from the inlet end to the outlet end, so that the pin 12 can smoothly enter the pin feeding guide 522 along the guide groove 52111.

[0070] Reference Figure 9 , Figure 11 and Figure 12 The mounting platform 512 is provided with a pin feeding guide rail 5121. The pin feeding platform 523 is slidably connected to the mounting platform 512 along the pin feeding guide rail 5121. The driving end of the pin feeding drive component 524 is connected to the pin feeding platform 523 and is used to drive the pin feeding platform 523 to reciprocate along the pin feeding guide rail 5121. In this embodiment, the pin feeding drive component 524 is specifically selected as a servo cylinder. The pin feeding platform 523 is provided with a plurality of pin positioning holes 5231 for placing pins 12. The end of the pin feeding guide tube 522 away from the second vibrating plate 521 is connected to the pin positioning holes 5231. The size and height of the pin positioning holes 5231 are set such that only a single pin 12 can be inserted. Specifically, the number and positional relationship of the pin positioning holes 5231 and the pin 12 guide tubes correspond to the insertion holes 111 of the gear component 11. Mounting platform 512 is provided with mounting grooves 5122 for mounting pins 12 and gear components 11. Mounting plate 5123 is provided in mounting groove 5122. Mounting plate 5123 has pin fixing holes 51231 that correspond to the pin positioning holes 5231 on pin feeding platform 523. When the pin feeding drive 524 drives the pin feeding platform 523 to slide to the position of mounting plate 5123, the pin positioning holes 5231 of the pin feeding platform 523 correspond to the pin fixing holes 51231 of the mounting plate 5123. Under the action of gravity, the pin 12 located in the pin positioning hole 5231 will fall directly into the pin fixing hole 51231. Then the pin feeding drive 524 drives the pin feeding platform 523 to slide back, thus completing the pin feeding action of the pin feeding platform 523.

[0071] Reference Figure 9 , Figure 11 and Figure 12 The mounting module 53 includes a mounting bracket 531, a pressing component 532, and an upward pushing component 533. The pressing component 532 is mounted on the mounting bracket 531 and includes a pressing drive 5321 and a stripping rod 5322. The mounting bracket 531 supports the pressing drive 5321 directly above the mounting platform 512. The driving end of the pressing drive 5321 extends vertically downward and connects to the stripping rod 5322. The stripping rod 5322 extends vertically downward and corresponds to the mounting plate 5123. The pressing drive 5321 drives the stripping rod 5322 to reciprocate towards the mounting plate 5123, thereby achieving the pressing action. Furthermore, a pressing pad 5323 is provided at the end of the stripping rod 5322 away from the pressing drive 5321. The pressing pad 5323 is used to reduce the impact force of the stripping rod 5322 on the gear component 11. A pressure sensor 5324 is also provided between the stripper rod 5322 and the pressing drive 5321. The pressure sensor 5324 is used to detect and limit the pressing pressure when the pressing drive 5321 drives the stripper rod 5322, so as to prevent the pressing drive 5321 from applying too much pressure to the stripper rod 5322, which could damage the gear 11 or the pin 12. Specifically, in this embodiment, the pressing drive 5321 is a servo cylinder.

[0072] Reference Figure 9 , Figure 11 and Figure 12 The push assembly 533 is fixedly disposed directly below the mounting platform 512. The push assembly 533 includes a push drive 5331, a push rod 5332, a push plate 5333, and a pin 5334. The drive end of the push drive 5331 extends vertically upward and is connected to the push rod 5332. The end of the push rod 5332 away from the push drive 5331 is connected to the push plate 5333. The push plate 5333 is slidably disposed in the mounting groove 5122 of the mounting platform 512. Thus, the push plate 5333 can reciprocate toward the mounting plate 5123 by the drive of the push drive 5331 and the push rod 5332, thereby realizing the upward push operation. Additionally, the ejector pin 5334 is inserted into the upper push rod 5332 and the upper push plate 5333. The ejector pin 5334 can be driven independently by the upper push drive 5331 and is used to push the assembled assembly 1 upward so that the subsequent moving claw mechanism 6 can clamp the assembly 1. Specifically, the upper push drive 5331 is a multi-stage servo cylinder.

[0073] Reference Figure 12Furthermore, a certain space is reserved between the upper push plate 5333 and the mounting plate 5123, and the distance from the top side of the mounting plate 5123 to the top side of the upper push plate 5333 is the same as the length of a single pin 12. Thus, when the pin 12 of the pin feeding table 523 falls into the pin fixing hole 51231 of the mounting plate 5123, due to the support of the upper push plate 5333, the pin 12 can just fill the pin fixing hole 51231 of the mounting plate 5123. At this time, the pin 12 and the next pin 12 will not affect the sliding of the pin feeding table 523, thereby ensuring the smooth operation of the pin feeding module 52.

[0074] Reference Figure 13 and Figure 14 To improve the success rate of pin 12 installation, a pin detection component 534 and a secondary pressing component 535 are also provided on the side of the mounting bracket 531 near the discharge table 513. The pin detection component 534 and the secondary pressing component 535 are electrically connected to each other. The pin detection component 534 is used to detect whether the pin 12 is installed in place, while the secondary pressing component 535 can cooperate with the discharge table 513 to perform a secondary pressing installation on the gear component 11 and the pin 12 based on the detection status of the pin detection component 534, to ensure that the pin 12 is fully installed. Specifically, the pin detection component 534 extends into several pin probes 5341, which are respectively set on both sides of the mounting table 512 according to the number and placement of the pins 12. In this embodiment, a total of four pin probes 5341 are provided. Four pin probes 5341 are respectively disposed on both sides of the mounting platform 512 and are laterally aligned with the four pin fixing holes 51231 on the mounting plate 5123. The pin probes 5341 are used to detect whether each pin 12 is installed in place. If each pin 12 is installed in place, the detected pin 12 lengths are consistent. Conversely, if the detected pin 12 length is longer, it is not installed in place and a secondary pressing assembly 535 is required for secondary pressing and installation. In this embodiment, the pin detection component 534 is an infrared detector, and the pin probes 5341 are infrared detection probes 422.

[0075] Reference Figure 14The secondary pressing assembly 535 includes a secondary pressing drive 5351, a secondary stripping rod 5352, and a secondary pressure plate 5353. The secondary pressure plate 5353 is mounted on the discharge platform 513 and has several fixed-length blind holes 53531. These blind holes 53531 correspond to the pins 12 on the gear component 11, and the depth of each blind hole 53531 is the same as the length of the pin 12 when it is fully installed on the gear component 11. The secondary pressing drive 5351 is mounted directly above the discharge platform 513 and corresponds to the secondary pressure plate 5353. The drive end of the secondary pressing drive 5351 extends vertically downward and connects to the secondary stripping rod 5352. When the gear component 11 and the pin 12 are moved onto the discharge table 513, the pin 12 will accurately fall into the fixed-length blind hole 53531. If the pin 12 is not installed in place, the gear component 11 will protrude relative to the upper surface of the secondary pressure plate 5353. At this time, the secondary pressing drive component 5351 will drive the secondary stripping rod 5352 to press down, so that the gear component 11 and the pin 12 can be fully installed. Specifically, in this embodiment, the secondary pressing drive component 5351 is a servo cylinder.

[0076] Reference Figure 15 The claw-shifting mechanism 6 includes a moving module 61 and a gripper module 62. The moving module 61 drives the gripper module 62 to move and lift. The moving module 61 includes a claw-shifting slide 611 and a claw-shifting lifting member 612. The claw-shifting lifting member 612 is disposed on the claw-shifting slide 611, and the gripper module 62 is disposed at the lifting end of the claw-shifting lifting member 612. The claw-shifting slide 611 drives the claw-shifting lifting member 612 and the gripper module 62 to slide longitudinally and laterally, while the claw-shifting lifting member 612 drives the gripper module 62 to lift, thereby enabling the gripper module 62 to move and lift in multiple directions. Specifically, in this embodiment, the claw-shifting slide 611 is a cross slide, and the claw-shifting lifting member 612 is a slide cylinder.

[0077] Reference Figure 2 and Figure 15The gripper module 62 includes a gripper arm 621, which is fixedly installed on the lifting end of the gripper lifting component 612 and can move and lift via the gripper slide 611 and the gripper lifting component 612. A first gripper 622, a second gripper 623, and a third gripper 624 are sequentially arranged on the gripper arm 621, and the positions of the first gripper 622, the second gripper 623, and the third gripper 624 correspond to the positions of the transfer table 511, the mounting table 512, and the unloading table 513, respectively. When the shifting claw slide 611 drives the gripper arm 621 to slide laterally, the first gripper 622 can reciprocate between the transfer table 511 and the mounting table 512, the second gripper 623 can reciprocate between the mounting table 512 and the discharge table 513, and the third gripper 624 can reciprocate between the discharge table 513 and the discharge port 21. Thus, the gripper module 62 can simultaneously complete three moving actions: moving the gear component 11 from the transfer table 511 to the mounting table 512, moving the gear component 11 from the mounting table 512 to the discharge table 513, and moving the gear component 11 from the discharge table 513 to the discharge port 21. This not only greatly improves the moving efficiency of the shifting claw mechanism 6, but also allows the installation process of the gear component 11 and the pin 12 to be carried out continuously like an assembly line, which is conducive to improving the installation efficiency of the installation equipment. In this embodiment, the first gripper 622, the second gripper 623, and the third gripper 624 are all flexible gripper cylinders. In other embodiments, the first gripper 622, the second gripper 623, and the third gripper 624 can also be electromagnetic chucks, which grip the gear component 11 by electromagnetic adsorption.

[0078] The implementation principle of the automatic pin installation equipment for powder metallurgy gear parts in this application embodiment is as follows:

[0079] When it is necessary to prepare the assembly 1 for planetary gear transmission, the gear component 11 is first fed through the first vibratory plate 31 and then enters the feeding channel 321. Through the vibration of the feeding drive component 322, the gear components 11 located in the feeding channel 321 are arranged in sequence and gradually moved to the testing table 41, thus completing the feeding process of the gear component 11.

[0080] Next, the detection probe 422 detects the placement and angle of the gear component 11 on the detection table 41. Then, the calibration module 43 moves the calibration claw 4342 above the detection table 41 via the calibration slide 431 and the calibration lifting component 433. The calibration drive component 4343 drives the calibration claw 4342 to rotate, so that the calibration positioning component 43421 on the calibration claw 4342 corresponds to the insertion hole 111 of the gear component 11. Then, the calibration claw 4342 uses electromagnetic adsorption to pick up the gear component 11, and moves and places the gear component 11 on the transfer table 511 by the drive of the calibration slide 431 and the calibration lifting component 433. During the movement, the calibration drive component 4343 drives the calibration claw 4342 to rotate again, so that the gear component 11 can rotate to the preset placement position and angle, thus completing the detection and calibration process of the gear component 11.

[0081] While inspecting and calibrating the gear component 11, the feeding process of the pin 12 needs to be carried out. First, the pin 12 is fed through the second vibratory feeder 521, and then enters the distributor 5211. In the distributor 5211, the pin 12 enters the pin feeding guide 522 along the guide groove 52111, and enters the pin positioning hole 5231 of the pin feeding table 523 by gravity. Then, the pin feeding drive 524 pushes the pin feeding table 523 to slide along the pin feeding guide rail 5121 of the mounting table 512. When the pin positioning hole 5231 of the pin feeding table 523 is aligned with the pin fixing hole 51231 on the mounting plate 5123, the pin 12 located in the pin positioning hole 5231 falls directly into the pin fixing hole 51231. Then, the pin feeding drive 524 drives the pin feeding table 523 to slide back, thus completing the feeding process of the pin 12. As the upper push plate 5333 provides support, after the pin 12 falls into the pin fixing hole 51231, the top of the pin 12 is just level with the top side of the mounting plate 5123, so it will not interfere with the sliding of the pin feeding table 523.

[0082] After completing the feeding process of pin 12, the installation process can officially begin. First, the first gripper 622 clamps the calibrated gear component 11 from the transfer table 511. Then, driven by the shifting claw slide 611 and the shifting claw lifting component 612, the gear component 11 is moved from the transfer table 511 to the mounting plate 5123 of the mounting platform 512. At this time, the insertion hole 111 of the gear component 11 corresponds to the pin fixing hole 51231 of the mounting plate 5123. Then, the downward driving component 5321 and the upward driving component 5331 are activated simultaneously. The downward driving component 5321 presses the gear component 11 downward through the stripping rod 5322, and the upward driving component 5331 pushes the pin 12 upward through the upward pushing rod 5332 and the upward pushing plate 5333. The two cooperate to allow the pin 12 to be fully inserted into the insertion hole 111 of the gear component 11. At this time, the installation process of the gear component 11 and the pin 12 is completed, and the assembly 1 is obtained.

[0083] After installation, the second gripper 623 picks up the assembly 1 from the mounting table 512 and moves it to the discharge table 513 via the shifting claw slide 611 and the shifting claw lifting component 612. During the process of picking up the assembly 1, the pin detection component 534 detects the extension length of the pin 12 through the pin probe 5341. If the length of the pin 12 is too long, the assembly 1 needs to be pressed and installed again on the discharge table 513. When the assembly 1 moves to the discharge table 513, the pin 12 is inserted into the fixed-length blind hole 53531. If the pin 12 is not installed in place, the secondary pressing drive component 5351 will press down and press and install the gear component 11 and the pin 12 again. Then the third gripper 624 can move the assembly 1 from the discharge table 513 to the discharge port 21 and complete the discharge of the assembly 1.

[0084] Since the entire installation process is carried out in an assembly line manner, without any manual operation or support, safety is improved. This not only greatly reduces the intensity of manual labor, but also helps to improve the installation efficiency of assembly 1.

After reading this specification, those skilled in the art can make modifications to this specific embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
