Description

Technical Field

[0001] The invention relates to the technical field of automation equipment, in particular to an automatic pin installation device for powder metallurgy gear parts. Background Art

[0002] The planetary pin is one of the main components of the planetary gear transmission device, in which the planetary pin is vertically arranged on the planetary gear part, and other sub-axles or bearings are rotatably mounted on the planetary pin. At present, conventional planetary gear parts are mass-cast by powder metallurgy, and the planetary pin is specifically a pin made of stainless steel or bearing steel. Due to the different materials and molding conditions of the planetary gear parts and planetary pins, the planetary gear parts and planetary pins are generally molded separately in production, and then the planetary pin is mounted on the planetary gear part by machining. For example, an existing assembly used in planetary gear transmission, refer to Figure 1 The assembly includes a gear part and a plurality of pins. The gear part is provided with a plurality of groups of plug holes, and the plurality of pins are vertically plugged into the plug holes of the gear part.

[0003] In existing machining technology, a pinning machine is usually used to complete the installation of planetary pins. As the name implies, a pinning machine installs pins into the plug-in holes of gear parts by pressing. Specifically, the staff will first place the formed gear part directly under the pressing part of the pinning machine, and then place the pins corresponding to the plug-in holes of the gear part. Finally, as the pressing part of the pinning machine presses, the pins as planetary pins are fully pressed into the gear part, thus completing the installation of the planetary pins.

[0004] Although pinning machines have been widely used in the field of planetary gear system processing, the existing pinning machines still have a low degree of automation. Whether it is the loading and unloading of gear parts or pins, or the positioning and installation of pins, they all require manual cooperation to complete, which undoubtedly greatly increases the labor intensity of the staff. In addition, since the staff needs to manually support the pins so that the pins can always be perpendicular to the gear parts when pressing, the pinning machine can only complete the installation of a single pin each time it is pressed. Not only is the installation efficiency low, but there are also great safety hazards when the staff supports. Summary of the invention

[0005] In order to improve the installation efficiency of pins on planetary gears, simplify the manual operation process, and improve safety, the present application provides an automatic pin installation device for powder metallurgy gear parts.

[0006] The present application provides an automatic pin installation device for powder metallurgy gear parts, which adopts the following technical solution: An automatic pin installation device for powder metallurgy gear parts, comprising a frame, and a wheel feeding mechanism, a detection mechanism, an assembly mechanism and a claw shifting mechanism which are sequentially installed on the frame; The frame is provided with a discharge port for discharging materials; The feeding mechanism comprises a first vibration plate for feeding gear parts, a feeding module is connected to the discharge end of the first vibration plate, the feeding module is connected to the first vibration plate and the detection mechanism, and is used to sequentially transport the gear parts from the first vibration plate to the detection mechanism; The detection mechanism includes a detection platform, a detection module and a correction module, wherein the discharge end of the feeding module is connected to the detection platform, the detection module is arranged on a side close to the detection platform, and is used to detect the placement position and angle of the gear part on the detection platform, and the correction module is used to move the gear part to the next process and correct the placement position and angle of the gear part during the movement; The assembly mechanism includes a press table module, a pin delivery module and an installation module.

The moving module is used to drive the clamping module to slide and rise and fall. The clamping module is used to clamp the gear part and cooperate with the moving module to enable the gear part to move in the assembly mechanism.

[0007] By adopting the above technical solution and through the mutual cooperation of the above multiple mechanisms, only a single installation device is required to complete the loading and installation process of gear parts and pins and the unloading process of the assembly. The entire process does not require operation and support from staff, which greatly simplifies the preparation process of the assembly, is conducive to improving the installation efficiency of the pins and reducing the labor intensity of the staff.

[0008] Optionally, the feeding module includes a feeding channel and a feeding drive, the feeding channel connects the first vibration plate and the detection platform, and the feeding channel extends obliquely downward toward the detection platform, the width of the feeding channel is equal to the width of the gear part, and feeding baffles are provided on the top of both sides of the feeding channel; the feeding drive is used to drive the feeding channel to vibrate.

[0009] By adopting the above technical solution, since the width of the feeding channel is equal to the width of the gear parts, the gear parts can enter the feeding channel one by one and be arranged in a row, which is conducive to the subsequent detection mechanism to detect the gear parts one by one. At the same time, since the feeding drive part moves the gear parts by vibrating the feeding channel, the feeding stop bars arranged on both sides of the feeding channel can effectively prevent the gear parts from being shaken out of the feeding channel, which is conducive to ensuring the transmission stability of the gear parts.

[0010] Optionally, the detection module includes a detection bracket, a detection probe and an adjustable lens, the detection bracket mounts the detection probe and the adjustable lens directly above the detection platform, and the adjustable lens is slidably disposed between the detection probe and the detection platform.

[0011] By adopting the above technical solution, the distance between the adjustable lens and the detection probe can be adjusted by sliding, and then the detection focal length of the detection probe can be adjusted, which is beneficial to improving the detection accuracy of the detection probe.

[0013] By adopting the above technical scheme, the correction claw can move the gear part on the detection table to the next process by driving the correction slide and the correction lifting part. Moreover, during the movement of the correction claw, the correction driving part can also drive the correction claw to rotate according to the detection situation of the detection module, and rotate and adjust the placement position and angle of the gear part, which is beneficial for the pin to be accurately inserted into the plug-in hole of the gear part during subsequent installation, which is beneficial for improving the installation yield rate.

[0014] Optionally, the pin delivery module includes a second vibration disk, a pin delivery conduit, a pin delivery platform and a pin delivery driving component, the pin delivery platform is provided with a plurality of groups of pin positioning holes, the pin delivery conduit connects the second vibration disk and the pin delivery platform, the mounting platform is provided with a mounting plate, the mounting plate is provided with pin fixing holes, the pin fixing holes correspond to the pin positioning holes, and the pin delivery driving component is used to drive the pin delivery platform to slide back and forth toward the mounting plate.

[0015] By adopting the above technical solution, the pins can be loaded through the second vibration plate, and guided by the pin feeding guide tube into the pin positioning hole of the pin feeding platform. When the pin feeding drive pushes the pin feeding platform to slide in the direction of the mounting plate, the pins can slide with the pin feeding platform in the pin positioning hole. When the pin positioning hole of the pin feeding platform and the pin fixing hole on the mounting plate are aligned with each other, the pins in the pin positioning hole directly fall into the pin fixing hole of the mounting plate, and then the pin feeding drive can drive the pin feeding platform to slide back. At this time, the required installation pins are placed in the mounting plate of the mounting platform. The mounting plate can not only position the pins for subsequent precise installation, but also support the pins without the need for additional operations by the staff, which is conducive to reducing the labor intensity of the staff.

[0016] Optionally, the second vibration plate is provided with a diverter, a guide groove is opened inside the diverter, the guide groove is wide at first and then narrow from the feed end to the discharge end, and the pin delivery conduit is connected to the discharge end of the diverter.

[0017] By adopting the above technical solution, since the guide groove in the diverter is wide at first and narrow at the end, the pin on the second vibration disk can enter the diverter more easily, and the guide groove in the diverter can also guide the pin, which is conducive to the pin smoothly entering the pin delivery guide tube.

[0018] Optionally, the mounting module includes a mounting bracket, a downward pressing component and an upward pushing component, the downward pressing component includes a downward pressing driving member and a stripping rod, the mounting bracket sets the downward pressing driving member just above the mounting plate, and the downward pressing driving member is used to drive the stripping rod to reciprocate toward the mounting plate; The push-up assembly is arranged on the bottom side of the mounting platform, and the push-up assembly includes a push-up driving member, a push-up rod and a push-up plate. The push-up rod connects the push-up driving member and the push-up plate, and the push-up driving member drives the push-up plate to reciprocate toward the mounting plate through the push-up rod.

[0019] By adopting the above technical scheme, when the gear part and the pin need to be installed, the downward pressing drive member and the upward pushing drive member are started at the same time, wherein the downward pressing drive member presses the gear part downward through the stripping rod, and the upward pushing drive member pushes the pin upward through the upper pushing rod and the upper pushing plate. The downward pressing component and the upper pushing component cooperate with each other, thereby effectively enabling the pin to be fully inserted into the plug-in hole of the gear part, which is beneficial to improving the installation yield rate.

[0020] Optionally, a space is reserved between the upper push plate and the mounting plate, and the distance from the top side of the upper push plate to the top side of the mounting plate is the same as the length of a single pin.

[0021] By adopting the above technical solution, when the pin of the pin delivery platform falls into the pin fixing hole of the mounting plate, the top of the pin is just flush with the top side of the mounting plate through the support of the push-up plate and the support of the mounting plate. At this time, the intersection of the pin and the next pin is just flush with the intersection of the pin delivery platform and the mounting platform, which will not interfere with the sliding of the pin delivery platform, and is conducive to ensuring the smooth operation of the pin delivery module.

[0022] Optionally, the press table module further includes a transfer table and a discharging table, the transfer table and the discharging table are respectively arranged on both sides of the mounting table, the discharging port is located on a side of the discharging table away from the mounting table, and the transfer table, the mounting table, the discharging table and the discharging port are evenly spaced; The clamping module includes a clamping arm, which is arranged on the moving module. The clamping arm is provided with a first clamping jaw, a second clamping jaw and a third clamping jaw in sequence. The first clamping jaw, the second clamping jaw and the third clamping jaw correspond to the transfer table, the mounting table and the discharging table respectively.

[0023] By adopting the above technical scheme, since the turntable, the mounting table, the discharging table and the discharging port are evenly spaced, when the moving module drives the clamping jaw arm to slide, the first clamping jaw can move back and forth between the turntable and the mounting table, the second clamping jaw can move back and forth between the mounting table and the discharging table, and the third clamping jaw can move back and forth between the discharging table and the discharging port. Therefore, the clamping jaw module can simultaneously complete the three moving actions of moving the gear part from the turntable to the mounting table, moving the gear part from the mounting table to the discharging table, and moving the gear part from the discharging table to the discharging port, thereby greatly improving the moving efficiency of the jaw mechanism and enabling the installation process of the gear part and the pin to be carried out continuously like an assembly line, which is beneficial to improving the installation efficiency of the installation equipment.

[0024] Optionally, the first clamp, the second clamp and the third clamp are any one of a flexible clamp cylinder or an electromagnetic suction cup.

[0025] By adopting the above technical solution, when the first clamp, the second clamp and the third clamp are made of flexible clamp cylinders, the physical clamping force on the gear part can be accurately controlled. Since most of the gear parts are made of powder metallurgy, it is helpful to reduce the adverse effects of clamping on the gear part. In addition, when the first clamp, the second clamp and the third clamp are made of electromagnetic suction cups, the gear part can be adsorbed, grasped and put down only by electrical control, and at the same time, it will not cause adverse effects such as clamping damage to the gear part, which is beneficial to protect the gear part.

The whole process does not require the operation and support of the staff, which greatly simplifies the preparation process of the assembly, is conducive to improving the installation efficiency of the pins and reducing the labor intensity of the staff.

The mounting platform 512 is provided with a mounting groove 5122 for mounting the pin 12 and the gear member 11, and a mounting plate 5123 is provided in the mounting groove 5122. The mounting plate 5123 is provided with a pin fixing hole 51231 corresponding to the pin positioning hole 5231 on the pin delivery platform 523. When the pin delivery driving member 524 drives the pin delivery platform 523 to slide to the position of the mounting plate 5123, the pin positioning hole 5231 of the pin delivery platform 523 corresponds to the pin fixing hole 51231 of the mounting plate 5123, and the pin 12 located in the pin positioning hole 5231 will directly fall into the pin fixing hole 51231 through the action of gravity, and then the pin delivery driving member 524 drives the pin delivery platform 523 to slide back, thus completing the pin delivery action of the pin delivery platform 523.

The pressing assembly 532 is mounted on the mounting bracket 531, and the pressing assembly 532 includes a pressing driving member 5321 and a stripping rod 5322. The mounting bracket 531 sets the pressing driving member 5321 just above the mounting platform 512. The driving end of the pressing driving member 5321 extends vertically downward and is connected to the stripping rod 5322. The stripping rod 5322 extends vertically downward and corresponds to the mounting plate 5123. The pressing driving member 5321 is used to drive the stripping rod 5322 to reciprocate toward the mounting plate 5123, thereby realizing the pressing action. Further, a pressing pad 5323 is provided at one end of the stripping rod 5322 away from the pressing driving member 5321, and the pressing pad 5323 is used to reduce the pressing impact force of the stripping rod 5322 on the gear member 11. A pressure sensor 5324 is also provided between the stripping rod 5322 and the pressing driving member 5321. The pressure sensor 5324 is used to detect and limit the pressing pressure when the pressing driving member 5321 drives the stripping rod 5322, so as to prevent the pressing driving member 5321 from applying too high pressure to drive the stripping rod 5322, thereby causing damage to the gear member 11 or the pin 12. Specifically, in this embodiment, the pressing driving member 5321 uses a servo cylinder.

[0057] Reference Fig. 9 , Fig.11 and Fig.12 The upper push assembly 533 is fixedly arranged directly below the mounting platform 512, and the upper push assembly 533 includes an upper push driving member 5331, an upper push rod 5332, an upper push plate 5333 and a push pin 5334. The driving end of the upper push driving member 5331 extends vertically upward and is connected to the upper push rod 5332, and the upper push rod 5332 is connected to the upper push plate 5333 at one end away from the upper push driving member 5331. The upper push plate 5333 is slidably arranged in the mounting groove 5122 of the mounting platform 512, so that the upper push plate 5333 can reciprocate toward the mounting plate 5123 through the drive of the upper push driving member 5331 and the upper push rod 5332, thereby realizing the upward push action. In addition, 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 driving member 5331, and is used to push the assembled assembly 1 upwards, so that the subsequent claw mechanism 6 can clamp the assembly 1. Specifically, the upper push driving member 5331 uses a multi-stage servo cylinder.

[0058] Reference Fig.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. Therefore, when the pin 12 of the pin delivery platform 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 just not affect the sliding of the pin delivery platform 523, thereby ensuring the smooth operation of the pin delivery module 52.

[0059] Reference Fig.13 and Fig.14 In order to improve the success rate of the installation of the pin 12, a pin detection member 534 and a secondary pressing assembly 535 are also provided on the side of the mounting bracket 531 close to the discharge platform 513, wherein the pin detection member 534 and the secondary pressing assembly 535 are electrically connected to each other, the pin detection member 534 is used to detect whether the pin 12 is installed in place, and the secondary pressing assembly 535 can cooperate with the discharge platform 513 to perform secondary pressing installation on the gear member 11 and the pin 12 according to the detection condition of the pin detection member 534, so as to ensure that the pin 12 is fully installed. Specifically, the pin detection member 534 extends a plurality of pin probes 5341, and the plurality of pin probes 5341 are respectively provided on both sides of the mounting platform 512 corresponding 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 arranged on both sides of the mounting platform 512 and are respectively aligned horizontally 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 length of the detected pins 12 is consistent. On the contrary, if the length of the detected pin 12 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 member 534 uses an infrared detector, and the pin probe 5341 uses an infrared detection probe 422.

[0060] Reference Fig.14The secondary pressing assembly 535 includes a secondary pressing driving member 5351, a secondary stripping rod 5352 and a secondary pressing plate 5353, wherein the secondary pressing plate 5353 is arranged on the discharge platform 513, and the secondary pressing plate 5353 is provided with a plurality of fixed-length blind holes 53531, which correspond to the pins 12 on the gear member 11, and the depth of the fixed-length blind holes 53531 is the same as the length of the pins 12 when they are fully installed on the gear member 11. The secondary pressing driving member 5351 is mounted directly above the discharge platform 513 and corresponds to the secondary pressing plate 5353, and the driving end of the secondary pressing driving member 5351 extends vertically downward and is connected to the secondary stripping rod 5352. When the gear member 11 and the pin 12 are moved to the unloading platform 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 member 11 will be raised relative to the upper surface of the secondary pressing plate 5353. At this time, the secondary pressing driving member 5351 will drive the secondary stripping rod 5352 to press downward, so that the gear member 11 and the pin 12 can be fully installed. Specifically, in this embodiment, the secondary pressing driving member 5351 uses a servo cylinder.

[0061] Reference Fig.15 The claw mechanism 6 includes a moving module 61 and a clamping module 62, wherein the moving module 61 is used to drive the clamping module 62 to move and lift. The moving module 61 includes a claw slide 611 and a claw lifting member 612, wherein the claw lifting member 612 is arranged on the claw slide 611, and the clamping module 62 is arranged at the lifting end of the claw lifting member 612, wherein the claw slide 611 is used to drive the claw lifting member 612 and the clamping module 62 to slide in the longitudinal and transverse directions, and the claw lifting member 612 is used to drive the clamping module 62 to lift, thereby realizing that the clamping module 62 can move and lift in multiple directions. Specifically, in this embodiment, the claw slide 611 uses a cross slide, and the claw lifting member 612 uses a slide cylinder.

[0062] Reference Figure 2 and Fig.15The clamping claw module 62 includes a clamping claw arm 621, which is fixedly mounted on the lifting end of the jaw lifting member 612 and can be moved and lifted by the jaw sliding platform 611 and the jaw lifting member 612. The clamping claw arm 621 is provided with a first clamping claw 622, a second clamping claw 623 and a third clamping claw 624 in sequence, and the positions of the first clamping claw 622, the second clamping claw 623 and the third clamping claw 624 correspond to the positions of the transfer table 511, the mounting table 512 and the discharge table 513 respectively. When the claw slide 611 drives the clamp arm 621 to slide horizontally, the first clamp 622 can move back and forth between the transfer table 511 and the mounting table 512, the second clamp 623 can move back and forth between the mounting table 512 and the discharge table 513, and the third clamp 624 can move back and forth between the discharge table 513 and the discharge port 21, so that the clamp module 62 can simultaneously complete the three moving actions of moving the gear part 11 from the transfer table 511 to the mounting table 512, moving the gear part 11 from the mounting table 512 to the discharge table 513, and moving the gear part 11 from the discharge table 513 to the discharge port 21. This not only greatly improves the moving efficiency of the claw mechanism 6, but also enables the installation process of the gear part 11 and the pin 12 to be carried out continuously like an assembly line, which is beneficial to improving the installation efficiency of the installation equipment. In this embodiment, the first clamp 622, the second clamp 623 and the third clamp 624 are all made of flexible clamp cylinders. In other embodiments, the first clamp 622, the second clamp 623 and the third clamp 624 can also be made of electromagnetic suction cups to grasp the gear part 11 by electromagnetic adsorption.

[0063] The implementation principle of the automatic pin installation device for powder metallurgy gear parts in the embodiment of the present application is as follows: When it is necessary to prepare an assembly 1 for planetary gear transmission, the gear part 11 will first be loaded through the first vibration plate 31 and then enter the feeding channel 321. Through the vibration of the feeding drive 322, the gear parts 11 located in the feeding channel 321 are arranged in sequence and gradually moved to the detection table 41. At this time, the loading process of the gear part 11 is completed.

[0064] Next, the detection probe 422 will detect the placement position and angle of the gear part 11 on the detection table 41, and then the correction module 43 will move the correction claw 4342 to the top of the detection table 41 through the correction slide 431 and the correction lifting member 433, and the correction driving member 4343 will drive the correction claw 4342 to rotate, so that the correction positioning member 43421 on the correction claw 4342 corresponds to the plug-in hole 111 of the gear part 11, and then the correction claw 4342 will absorb and grasp the gear part 11 by electromagnetic adsorption, and through the drive of the correction slide 431 and the correction lifting member 433, the gear part 11 is moved and placed on the transfer table 511. During the movement, the correction driving member 4343 will drive the correction claw 4342 to rotate again, so that the gear part 11 can rotate to the preset placement position and angle, thereby completing the detection and correction process of the gear part 11.

[0065] While the gear part 11 is being inspected and corrected, the pin 12 needs to be loaded. First, the pin 12 is loaded through the second vibration plate 521, and then enters the diverter 5211. The pin 12 enters the pin delivery conduit 522 along the guide groove 52111 in the diverter 5211, and enters the pin positioning hole 5231 of the pin delivery platform 523 along the pin delivery conduit 522 by gravity. Then the pin delivery driving member 524 pushes the pin delivery platform 523 to slide along the pin delivery guide rail 5121 of the mounting platform 512. When the pin positioning hole 5231 of the pin delivery platform 523 is aligned with the pin fixing hole 51231 on the mounting plate 5123, the pin 12 located in the pin positioning hole 5231 directly falls into the pin fixing hole 51231, and then the pin delivery driving member 524 drives the pin delivery platform 523 to slide back, and the loading process of the pin 12 is completed. Among them, due to the support of the upper push plate 5333, after the pin 12 falls into the pin fixing hole 51231, the top end of the pin 12 is just flush with the top side of the mounting plate 5123, so it will not interfere with the sliding of the pin delivery platform 523.

[0066] After the loading process of the pin 12 is completed, the installation process can officially begin. First, the first clamping claw 622 clamps the calibrated gear part 11 from the turntable 511, and then the gear part 11 is moved from the turntable 511 to the mounting plate 5123 of the mounting table 512 by driving the claw sliding table 611 and the claw lifting member 612. At this time, the plug-in hole 111 of the gear part 11 corresponds to the pin fixing hole 51231 of the mounting plate 5123, and then the downward driving member 5321 and the upward driving member 5331 are started at the same time, wherein the downward driving member 5321 presses the gear part 11 downward through the stripping rod 5322, and the upward driving member 5331 pushes the pin 12 upward through the upper push rod 5332 and the upper push plate 5333, and they cooperate with each other, so that the pin 12 can be fully inserted into the plug-in hole 111 of the gear part 11, and the installation process of the gear part 11 and the pin 12 is completed, and the assembly 1 is obtained.

[0067] After the installation is completed, the second clamping jaw 623 clamps the assembly 1 on the mounting platform 512, and moves it to the discharge platform 513 through the claw sliding platform 611 and the claw lifting member 612. In the process of clamping the assembly 1, the pin detection member 534 detects the extension length of the pin 12 through the pin probe 5341. If the length of the pin 12 is too long, it is necessary to press and install the assembly 1 for the second time on the discharge platform 513. When the assembly 1 moves to the discharge platform 513, the pin 12 is inserted into the fixed-length blind hole 53531. If the pin 12 is not installed in place, the secondary downward pressure driving member 5351 will press down and press and install the gear member 11 and the pin 12 again. Then the third clamping jaw 624 can move the assembly 1 from the discharge platform 513 to the discharge port 21 and complete the discharge of the assembly 1.

[0068] Since the entire installation process is carried out in an assembly line manner without any manual operation or support, safety is improved, which not only greatly reduces the labor intensity, but also helps to improve the installation efficiency of the assembly 1.

[0069] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
