Description

Technical Field

[0001] This invention relates to the field of pipe fitting processing equipment, and in particular to a multi-station aluminum sleeve and steel core installation device. Background Technology

[0002] Currently, during the processing of automotive air conditioning aluminum sleeves, it is usually necessary to install parts such as aluminum sleeves and steel cores onto corresponding pipe fittings. Furthermore, during the installation of aluminum sleeves, the pipe fittings need to be extruded to ensure that the positioning ring structure formed by the extrusion can position the aluminum sleeve.

[0003] Existing pipe fitting processing equipment typically only processes one step of the pipe fitting process. This means that steps such as pipe extrusion, aluminum sleeve / steel core feeding, aluminum sleeve / steel core installation, and aluminum sleeve positioning need to be performed multiple times by multiple machines, which greatly reduces the efficiency of pipe fitting processing.

[0004] Meanwhile, existing aluminum sleeve / steel core installation equipment can usually only install specific aluminum sleeves or steel cores, or can be installed manually. The installation equipment cannot select different models of aluminum sleeves / steel cores, nor can it switch between aluminum sleeves and steel cores. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-station aluminum sleeve and steel core installation device that improves pipe fitting processing efficiency and allows for switching between aluminum sleeves and steel cores of different specifications.

[0006] To solve the above-mentioned technical problems, the present invention provides a multi-station aluminum sleeve and steel core installation device, including a head-supporting mechanism, an aluminum sleeve and steel core feeding mechanism, and an aluminum sleeve and steel core installation mechanism. The head-supporting mechanism and the aluminum sleeve and steel core installation mechanism have the same structure, and the head-supporting mechanism is equipped with a first positioning punch for extruding the pipe fitting once. The aluminum sleeve and steel core installation mechanism is equipped with an aluminum sleeve installation punch for installing the aluminum sleeve onto the pipe fitting and a steel core installation punch for installing the steel core onto the pipe fitting. The aluminum sleeve and steel core feeding mechanism includes an aluminum sleeve vibrating plate, a steel core vibrating plate, and feeding grippers. One side of the aluminum sleeve vibrating plate is connected to an aluminum sleeve material channel, and one side of the steel core vibrating plate is connected to a steel core material channel, so that the feeding grippers convey the aluminum sleeve in the aluminum sleeve material channel and the steel core in the steel core material channel to the aluminum sleeve installation punch and the steel core installation punch, respectively, and the aluminum sleeve installation punch and the steel core installation punch install the aluminum sleeve and the steel core onto the pipe fitting.

[0007] Furthermore, the aluminum sleeve material channel has a first discharge block at its discharge end and a second discharge block at its discharge end. The aluminum sleeve material channel also has a first fixing member at its discharge end and a second fixing member at its discharge end. This is so that after one aluminum sleeve enters the first discharge block from the aluminum sleeve material channel, the first fixing member fixes the aluminum sleeve at the discharge end of the aluminum sleeve material channel. Similarly, after one steel core enters the second discharge block from the steel core material channel, the second fixing member fixes the steel core at the discharge end of the steel core material channel.

[0008] Furthermore, a positioning plate is connected to the end of the first discharge block away from the aluminum sleeve material channel and the end of the second discharge block away from the steel core material channel. The positioning plate is provided with a first detection element corresponding to the first discharge block and a second detection element corresponding to the second discharge block. The first detection element is used to detect whether the aluminum sleeve is located in the first discharge block, and the second detection element is used to detect whether the steel core is located in the second discharge block.

[0009] Furthermore, an installation plate is provided on one side of the aluminum sleeve material channel and the steel core material channel, and an aluminum sleeve linear vibrator is connected between the aluminum sleeve material channel and the installation plate, and a steel core linear vibrator is connected between the steel core material channel and the installation plate, so that when the aluminum sleeve linear vibrator and the steel core linear vibrator are started, the aluminum sleeve and the steel core move along the aluminum sleeve material channel and the steel core material channel respectively.

[0010] Furthermore, the aluminum sleeve steel core feeding mechanism also includes a positioning bracket, the mounting plate, the first detection component and the second detection component are connected to the positioning bracket, and the first discharge block and the second discharge block are detachably connected to the positioning bracket through a connector.

[0011] Furthermore, both the first and second discharge blocks have clearance grooves on their sides so that the feeding claws can clamp the aluminum sleeve or steel core from the clearance grooves.

[0012] Furthermore, a first material channel mounting plate is connected between the aluminum sleeve material channel and the aluminum sleeve linear vibrator, and a second material channel mounting plate is connected between the steel core material channel and the steel core linear vibrator. The aluminum sleeve material channel and the first material channel mounting plate are detachably connected, and the steel core material channel and the second material channel mounting plate are detachably connected.

[0013] Furthermore, the aluminum sleeve vibratory feeder includes an upper aluminum sleeve plate and an aluminum sleeve base plate, which are detachably connected. The steel core vibratory feeder includes an upper steel core plate and a steel core base plate, which are detachably connected. The aluminum sleeve feed channel is connected to the upper aluminum sleeve plate, and the steel core feed channel is connected to the upper steel core plate.

[0014] Furthermore, the aluminum sleeve chassis is mounted on the frame, and several adjusting rods are connected between the aluminum sleeve chassis and the frame so that the height of the aluminum sleeve chassis can be adjusted by the adjusting rods. The steel core chassis is mounted on the frame, and several adjusting rods are connected between the steel core chassis and the frame so that the height of the steel core chassis can be adjusted by the adjusting rods.

[0015] Furthermore, the loading gripper includes an aluminum sleeve gripper and a steel core gripper. The loading gripper is connected to the robot arm fixing block. The robot arm fixing block is in movable engagement with the robot arm mounting plate via a first linear guide. One side of the robot arm mounting plate is movably mounted on a second linear guide. When the robot arm fixing block moves along the first linear guide, the loading gripper moves horizontally. When the robot arm mounting plate moves along the second linear guide, the loading gripper moves horizontally as well. The movement directions of the first linear guide and the second linear guide are intersected. A lifting mechanism is connected between the loading gripper and the robot arm fixing block so that the loading gripper can be raised and lowered via the lifting mechanism.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. By using aluminum sleeve vibratory feeders and steel core vibratory feeders in conjunction with aluminum sleeve material channels and steel core material channels, the aluminum sleeves and steel cores can be automatically fed without manual feeding.

[0018] 2. The first and second discharge blocks ensure stable discharge of the aluminum sleeve and steel core;

[0019] 3. The first and second detection pieces perform position detection on the aluminum sleeve and steel core, and work with the first and second fixing pieces to position the aluminum sleeve and steel core in the material channel, thereby improving the stability of the aluminum sleeve and steel core during the feeding process and avoiding interference between the material in the material channel and the gripper, or the material in the first and second discharge blocks being blocked by the subsequent material in the material channel, which would make it difficult for the feeding gripper to pick up the material.

[0020] 4. The detachable connection between the aluminum sleeve / steel core upper plate and the aluminum sleeve / steel core base plate, as well as the detachable connection of the corresponding material channel, allows for the selection of the appropriate upper plate and material channel for the installation of aluminum sleeves / steel cores of different specifications.

[0021] 5. The aluminum sleeve and steel core are clamped by the feeding jaws and placed at the aluminum sleeve installation punch and steel core installation punch, thereby automatically installing the aluminum sleeve and steel core without manual installation;

[0022] 6. The first positioning punch and the aluminum sleeve installation punch squeeze the pipe fitting twice, so that the aluminum sleeve can be positioned at the designated position of the pipe fitting, improving the accuracy of the aluminum sleeve installation position.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0047] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0048] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0049] like Figure 1-22 The present invention provides a multi-station aluminum sleeve and steel core installation device, including a head-supporting mechanism 1, an aluminum sleeve and steel core feeding mechanism 5, and an aluminum sleeve and steel core installation mechanism 4; wherein, the head-supporting mechanism 1 and the aluminum sleeve and steel core installation mechanism 4 have the same structure, and the head-supporting mechanism 1 is equipped with a first positioning punch for extruding the pipe fitting 6 once, and the aluminum sleeve and steel core installation mechanism 4 is equipped with an aluminum sleeve 62 installation punch for installing the aluminum sleeve 62 onto the pipe fitting 6 and a steel core 63 installation punch for installing the steel core 63 onto the pipe fitting 6; The aluminum sleeve and steel core feeding mechanism 5 includes an aluminum sleeve vibrating plate, a steel core vibrating plate, and feeding grippers. One side of the aluminum sleeve vibrating plate is connected to an aluminum sleeve material channel 516, and one side of the steel core vibrating plate is connected to a steel core material channel 519, so that the feeding grippers can transport the aluminum sleeve 62 in the aluminum sleeve material channel 516 and the steel core 63 in the steel core material channel 519 to the aluminum sleeve 62 mounting punch and the steel core 63 mounting punch, respectively, and the aluminum sleeve 62 and the steel core 63 are mounted onto the pipe fitting 6 by the aluminum sleeve 62 mounting punch and the steel core 63 mounting punch.

[0050] Specifically, the aluminum sleeve 62 and steel core 63 to be loaded are placed in the vibratory feeders of aluminum sleeve 62 and steel core 63, respectively. The vibratory feeders of aluminum sleeve 62 and steel core 63 transport the corresponding aluminum sleeve 62 and steel core 63 to the aluminum sleeve material channel 516 and steel core material channel 519, respectively. Then, the aluminum sleeve 62 and steel core 63 are transported to the gripping position of the loading claw. The loading claw then grips and transports the aluminum sleeve 62 and steel core 63 to the installation punch of aluminum sleeve 62 and steel core 63, respectively, so that the aluminum sleeve 62 and steel core 63 are temporarily fitted onto the installation punch of aluminum sleeve 62 and steel core 63. Then, the installation punch of aluminum sleeve 62 and steel core 63 moves and presses towards the pipe fitting 6 in sequence, so that the aluminum sleeve 62 and steel core 63 are installed in the corresponding positions of the pipe fitting 6.

[0051] Specifically, the steel core 63 can be directly installed using the steel core 63 installation punch. When installing the aluminum sleeve 62, the pipe fitting 6 is squeezed once at the head mechanism 1, forming a first positioning ring 61 on the outer periphery of the pipe fitting 6. Then, the pipe fitting 6 moves to the side of the aluminum sleeve 62 installation punch, and the aluminum sleeve 62 is installed onto the pipe fitting 6 using the aluminum sleeve 62 installation punch. One side of the hole structure of the aluminum sleeve 62 abuts against the first positioning ring 61. At this time, the pipe fitting 6 is squeezed a second time using the aluminum sleeve installation punch, forming a second positioning ring 64 on the outer periphery of the pipe fitting 6. The second positioning ring 64 abuts against the other side of the hole structure of the aluminum sleeve 62, so that the first positioning ring 61 and the second positioning ring 64 clamp and position both sides of the hole structure of the aluminum sleeve 62 to ensure the accurate installation position of the aluminum sleeve 62.

[0052] This solution offers four installation options: installing the aluminum sleeve 62 alone, installing the steel core 63 alone, installing both the aluminum sleeve 62 and the steel core 63 simultaneously, or not installing either the aluminum sleeve 62 or the steel core 63. Users can choose the option that best suits their specific needs.

[0053] It is worth mentioning that the multi-station aluminum sleeve 62 and steel core 63 installation equipment in this scheme is also equipped with a feeding rack, a grooving mechanism 2, and a chamfering mechanism 3. When actually processing the pipe fitting 6, the processing flow can be followed as follows:

[0054] Pipe fitting 6 is fed → Pipe fitting 6 is extruded once by the head-forming mechanism 1 → Pipe fitting 6 is grooved by the grooving mechanism 2 → Pipe fitting 6 is chamfered by the chamfering mechanism 3 → Aluminum sleeve 62 and steel core 63 are conveyed by the feeding gripper to the aluminum sleeve 62 installation punch and steel core 63 installation punch → Installation is carried out according to one of the four installation methods selected by the user → Unloading.

[0055] The processing methods and structures of the feeding rack, the head-supporting mechanism 1, the swirl mechanism 2, and the chamfering mechanism 3 are all existing technologies and will not be described in detail here. Furthermore, the head-supporting mechanism 1, the swirl mechanism 2, and the chamfering mechanism 3 are all equipped with corresponding clamping structures 7. The pipe fitting 6 is clamped in the current processing mechanism for processing through the corresponding clamping structure 7. The clamping structure 7 is consistent with the existing clamping structure 7, and the clamping structure 7 in this solution is controlled by a cylinder or a hydraulic cylinder to clamp or release.

[0056] Meanwhile, the pipe fittings 6 between the feeding rack, the head-mounting mechanism 1, the swirl mechanism 2, the chamfering mechanism 3, and the aluminum sleeve steel core installation mechanism 4 are transported in a unified manner by several robotic arms. After the robotic arms clamp and pick up the pipe fittings 6 from the previous process, they carry the pipe fittings 6 to the corresponding clamping mold in the next process for fixing, thus completing the conveying action of the pipe fittings 6 between two adjacent processes.

[0057] In a preferred embodiment of this solution, the aluminum sleeve and steel core mounting mechanism 4 includes a clamping mold structure 7 and several different punches. Among the punches are aluminum sleeve 62 mounting punches and steel core 63 mounting punches, and all punches are mounted on a punch adjusting plate 41. The punch adjusting plate 41 is movably mounted on an adjusting rail 42 on one side. The punch adjusting plate 41 is controlled by a servo motor to move up and down along the adjusting rail 42. When the punch adjusting plate 41 moves, the corresponding positions between each punch and the pipe 6 held by the clamping mold structure 7 are switched, thereby switching to use different punches to perform different processing operations on the pipe 6. The adjusting rail 42 is set on a punch seat 43. The punch seat 43 is moved and stamped by a servo motor in conjunction with a lead screw. After the different punches are switched, the punch seat 43 drives several punches to move. At this time, the punch corresponding to the pipe 6 performs stamping processing on the pipe 6.

[0058] The first positioning punch 11 has an annular groove structure on the side facing the pipe 6, so that when the first positioning punch punches the pipe 6, the pipe 6 is squeezed at the position of the annular groove to generate the first positioning ring 61.

[0059] The aluminum sleeve mounting punch 44 also has an annular groove structure on the side facing the pipe fitting 6. After the aluminum sleeve 62 is temporarily fitted onto the outer periphery of the aluminum sleeve mounting punch 44, the aluminum sleeve mounting punch 44 pushes the aluminum sleeve 62 to the outer periphery of the pipe fitting 6. At the same time, the pipe fitting 6 is located at the position of the annular groove structure and simultaneously extrudes to generate the second positioning ring 64. Then, the hole structure at one end of the aluminum sleeve 62 is tightened and fixed by the first positioning ring 61 and the second positioning ring 64.

[0060] The steel core mounting punch 45 has a placement groove at one end facing the pipe fitting 6. The steel core 63 is temporarily placed in the placement groove. The steel core mounting punch 45 includes a punch sleeve 46, a punch seat 47 movably mounted inside the punch sleeve 46, and a punch core 48 connected to the punch seat 47 near the pipe fitting 6. When the steel core 63 is placed in the placement groove, the steel core 63 is located inside the punch sleeve 46 and is attached to one end of the punch core 48. When the steel core mounting punch 45 moves the steel core 63 toward the end of the pipe fitting 6, the punch sleeve 46 is blocked by the end of the pipe fitting 6, causing the punch sleeve 46 to stop moving. At this time, the punch seat 47 drives the punch core 48 to continue moving, and pushes the steel core 63 into the end of the pipe fitting 6 through the punch core 48 to complete the installation of the steel core 63. A spring is connected between the punch sleeve 46 and the punch seat 47 to ensure the reset of the punch sleeve 46 and the punch seat 47.

[0061] Preferably, the aluminum sleeve material channel 516 has a first discharge block 522 at its discharge end, and the steel core material channel 519 has a second discharge block 523 at its discharge end. The aluminum sleeve material channel 516 has a first fixing member 525 at its discharge end, and the steel core material channel 519 has a second fixing member 526 at its discharge end. This is so that after one aluminum sleeve 62 enters the first discharge block 522 from the aluminum sleeve material channel 516, the first fixing member 525 fixes the aluminum sleeve 62 at its discharge end. Similarly, after one steel core 63 enters the second discharge block 523 from the steel core material channel 519, the second fixing member 526 fixes the steel core 63 at its discharge end.

[0062] Specifically, the aluminum sleeve 62 and steel core 63 in the aluminum sleeve material channel 516 and the steel core material channel 519 are conveyed along the material channel and eventually moved to the first discharge block 522 and the second discharge block 523, so that the feeding claw can clamp and feed the aluminum sleeve 62 or the steel core 63.

[0063] Meanwhile, the aluminum sleeve 62 or steel core 63 at the discharge end of the material channel is positioned by the first fixing member 525 and the second fixing member 526 to prevent the material in the material channel from blocking the discharge end or pushing the material in the first / second discharge block 523, so as to ensure the stable feeding of the material in the first / second discharge block 523.

[0064] The first fixing member 525 and the second fixing member 526 can be cylinder structures, so that the piston rod of the cylinder extends to abut against the material in the material channel, so as to ensure that the material at the discharge end of the material channel stops moving.

[0065] It is worth mentioning that the aluminum sleeve 62 or steel core 63 in the first discharge block 522 and the second discharge block 523 can usually only enter one. That is to say, the material fixed by the first fixing member 525 and the second fixing member 526 is actually the second material (the first material is waiting to be loaded in the discharge block).

[0066] Preferably, a positioning plate 58 is connected to one end of the first discharge block 522 away from the aluminum sleeve material channel 516 and the other end of the second discharge block 523 away from the steel core material channel 519. The positioning plate 58 is provided with a first detection element 527 corresponding to the first discharge block 522 and a second detection element 528 corresponding to the second discharge block 523. The first detection element 527 is used to detect whether the aluminum sleeve 62 is located in the first discharge block 522, and the second detection element 528 is used to detect whether the steel core 63 is located in the second discharge block 523.

[0067] Specifically, the positioning plate 58 allows the aluminum sleeve 62 and steel core 63 to be limited after entering the first discharge block 522 and the second discharge block 523, preventing them from falling off the discharge block.

[0068] Simultaneously, the first detection element 527 and the second detection element 528 detect the material in the first discharge block 522 and the second discharge block 523. When the material is detected to have entered the corresponding discharge block, the signal can be fed back to the first fixing element 525 or the second fixing element 526 so that the first fixing element 525 and the second fixing element 526 can position the material at the discharge end of the material channel.

[0069] Among them, the first detection element 527 and the second detection element 528 can be fiber optic sensors.

[0070] Preferably, an mounting plate 515 is provided on one side of the aluminum sleeve material channel 516 and the steel core material channel 519, and an aluminum sleeve linear vibrator 517 is connected between the aluminum sleeve material channel 516 and the mounting plate 515, and a steel core linear vibrator 520 is connected between the steel core material channel 519 and the mounting plate 515, so that when the aluminum sleeve linear vibrator 517 and the steel core linear vibrator 520 are started, the aluminum sleeve 62 and the steel core 63 move along the aluminum sleeve material channel 516 and the steel core material channel 519 respectively.

[0071] Specifically, the aluminum sleeve / steel core linear vibrator 520 vibrates the aluminum sleeve / steel core material channel 519, so that the aluminum sleeve 62 / steel core 63 in the material channel can move along the material channel to the discharge block.

[0072] In one embodiment of this solution, the aluminum sleeve 62 / steel core material channel 519 can be inclined so that the connection between the material channel and the vibrating plate is higher than the connection between the material channel and the discharge block, so as to ensure stable material transmission.

[0073] In a preferred embodiment of this solution, a pause fiber optic sensor is also provided on the upper side of the aluminum sleeve 62 / steel core material channel 519 near the vibratory plate. When the pause fiber optic sensor detects that the material in the material channel has not moved within 5 seconds / 10 seconds, it can send a signal to the linear vibrator to pause, thus avoiding the problem of the vibratory plate having difficulty feeding due to excessive material in the material channel.

[0074] Preferably, the aluminum sleeve steel core feeding mechanism 5 further includes a positioning bracket 529, the mounting plate 515, the first detection element 527 and the second detection element 528 are connected to the positioning bracket 529, and the first discharge block 522 and the second discharge block 523 are detachably connected to the positioning bracket 529 through a connector.

[0075] Specifically, the positioning bracket 529 provides stable support for each component. Since the first / second discharge block 523 is detachably connected to the positioning bracket 529, when the specifications of the aluminum sleeve 62 / steel core 63 need to be changed, the first / second discharge block 523 of different specifications can be replaced accordingly.

[0076] The connecting parts can be screws, locating pins, etc.

[0077] Preferably, both the first discharge block 522 and the second discharge block 523 have clearance grooves 524 on their sides so that the feeding claws can clamp the aluminum sleeve 62 or the steel core 63 from the clearance grooves 524.

[0078] Specifically, by opening the clearance groove 524, when the feeding claw descends to clamp the aluminum sleeve 62 or the steel core 63, the two sides of the material can be exposed at the clearance groove 524 to facilitate the clamping operation.

[0079] Preferably, a first material channel mounting plate 518 is connected between the aluminum sleeve material channel 516 and the aluminum sleeve linear vibrator 517, and a second material channel mounting plate 521 is connected between the steel core material channel 519 and the steel core linear vibrator 520. The aluminum sleeve material channel 516 and the first material channel mounting plate 518 are detachably connected, and the steel core material channel 519 and the second material channel mounting plate 521 are detachably connected.

[0080] Specifically, due to the detachable connection of the aluminum sleeve 62 / steel core channel 519, when it is necessary to change the specifications of the aluminum sleeve 62 / steel core 63, the aluminum sleeve 62 / steel core channel 519 of different specifications can be replaced accordingly.

[0081] The aluminum sleeve material channel 516 and the first material channel mounting plate 518 are detachably connected by screws, bolts and other connecting parts, and the steel core material channel 519 and the second material channel mounting plate 521 are detachably connected by screws, bolts and other connecting parts.

[0082] Preferably, the aluminum sleeve vibratory feeder includes an upper aluminum sleeve plate 511 and an aluminum sleeve base plate 512, with the upper aluminum sleeve plate 511 and the aluminum sleeve base plate 512 being detachably connected. The steel core vibratory feeder includes an upper steel core plate 59 and a steel core base plate 510, with the upper steel core plate 59 and the steel core base plate 510 being detachably connected. The aluminum sleeve feed channel 516 is connected to the upper aluminum sleeve plate 511, and the steel core feed channel 519 is connected to the upper steel core plate 59.

[0083] Specifically, the upper aluminum sleeve plate 511 and the lower aluminum sleeve plate 512 are detachably connected by means of threaded connection, bolt connection, positioning pin, etc., so that the upper plate can be adapted to different specifications of aluminum sleeve 62 / steel core 63.

[0084] Preferably, the aluminum sleeve chassis 512 is mounted on the frame 513, and a plurality of adjusting rods 514 are connected between the aluminum sleeve chassis 512 and the frame 513 so that the height of the aluminum sleeve chassis 512 can be adjusted by the adjusting rods 514. The steel core chassis 510 is mounted on the frame 513, and a plurality of adjusting rods 514 are connected between the steel core chassis 510 and the frame 513 so that the height of the steel core chassis 510 can be adjusted by the adjusting rods 514.

[0085] Specifically, the height of the aluminum sleeve 62 / steel core chassis 510 is adjusted by several adjusting rods 514 to adapt to material channels of different heights, thereby ensuring that the aluminum sleeve 62 / steel core 63 can stably enter the material channel from the upper plate position.

[0086] The adjusting rod 514 includes an outer tube and an inner tube, which are threaded together. When the outer tube and the inner tube rotate relative to each other, the overall length of the adjusting rod 514 can be adjusted, thereby adjusting the height of the aluminum sleeve 62 / steel core chassis 510.

[0087] Preferably, the loading gripper includes an aluminum sleeve gripper 51 and a steel core gripper 52. The loading gripper is connected to the robot arm fixing block 54. The robot arm fixing block 54 is in movable engagement with the robot arm mounting plate 56 via a first linear guide 55. One side of the robot arm mounting plate 56 is movably mounted on a second linear guide 57. When the robot arm fixing block 54 moves along the first linear guide 55, the loading gripper moves horizontally. When the robot arm mounting plate 56 moves along the second linear guide 57, the loading gripper moves horizontally. The movement direction of the first linear guide 55 and the movement direction of the second linear guide 57 are intersected. A lifting mechanism 53 is connected between the loading gripper and the robot arm fixing block 54 so that the loading gripper can be lifted and lowered via the lifting mechanism 53.

[0088] Specifically, when the feeding gripper needs to feed the aluminum sleeve 62 / steel core 63, the robotic arm mounting plate 56 drives the feeding gripper to move along the second linear rail 57, so that the feeding gripper moves above the first / second discharge block 523. Then, the lifting mechanism 53 controls the feeding gripper to descend and clamp the material in the first / second discharge block 523. Then, the lifting mechanism 53 controls the feeding gripper to rise and reset, and the robotic arm mounting plate 56 moves in the opposite direction along the second linear rail 57, so that the feeding gripper moves to the upper side of the aluminum sleeve / steel core mounting mechanism 4. Then, the lifting mechanism 53 controls the feeding gripper to descend to the corresponding punch. At this time, the robotic arm fixing block 54 drives the feeding gripper to approach the punch along the first linear rail 55 and temporarily fits the aluminum sleeve 62 / steel core 63 onto the corresponding punch so that the punch can press the corresponding material onto the pipe fitting 6.

[0089] The movement of the robot arm fixing block 54 and the first linear rail 55 is controlled by a cylinder, and the movement of the robot arm mounting plate 56 and the second linear rail 57 is controlled by a servo motor. The lifting mechanism 53 can be a cylinder structure to control the lifting of the loading gripper. At the same time, the aluminum sleeve gripper 51 and the steel core gripper 52 both adopt the existing gripper structure, which will not be described in detail here.

[0090] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
