It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0051] In the description of this utility model, it should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance.

[0052] like Figure 1-11 As shown in the figure, this utility model embodiment proposes an intelligent automatic assembly line for piston rods, including a first workbench 1, a second workbench 7, and a conveyor belt 12. The first workbench 1 is sequentially equipped with a workpiece loading mechanism 2, an oil seal cap loading mechanism 3, an oil seal loading mechanism 4, a guide loading mechanism 5, and a spring loading mechanism 6 from left to right. The first workbench 1 is also equipped with a circular conveyor line 13, which is located on one side of each of the above mechanisms and is used for conveying workpieces between the mechanisms. The second workbench 7 is equipped with a turntable 71 and nut tightening mechanisms 8, riveting mechanisms 9, and unloading mechanisms 10 arranged at intervals along the circumferential direction of the turntable 71. The conveyor belt 12 is located at the end of the first workbench 1 and the beginning of the second workbench 7, respectively, and is used to receive the workpieces conveyed by the circular conveyor line 13 and perform manual assembly of some parts during the conveying process, thereby conveying the assembled workpieces to the second workbench 7.

[0053] In this embodiment of the invention, during operation, the workpiece is automatically placed onto the circular conveyor line 13 by the workpiece loading mechanism 2. It then sequentially passes through the oil seal cap loading mechanism 3, the oil seal loading mechanism 4, the guide loading mechanism 5, and the spring loading mechanism 6 along the circular conveyor line 13. Each mechanism automatically loads corresponding components onto the workpiece, completing the automatic assembly of the initial basic components. The pre-assembled workpiece is then conveyed by the circular conveyor line 13 to the end of the first workbench 1, and then transferred by the conveyor belt 12 to the front of the second workbench 7. Simultaneously, during the conveying process, the operator manually assembles some parts (piston check valve, piston, piston plate, nut, etc.) onto the workpiece. The assembled workpiece then enters the second workbench 7, where the turntable 71 sequentially delivers the workpiece to the nut tightening mechanism 8 and the riveting mechanism 9, where the equipment automatically completes the thread tightening and riveting actions. Finally, the tightened and riveted workpiece is unloaded by the unloading mechanism 10, completing the assembly process of the entire production line. This embodiment combines automatic feeding with automated assembly and manual processing, giving full play to the advantages of high equipment efficiency and manual flexibility, thereby improving overall assembly quality and production efficiency.

[0054] Specifically, such as Figure 4-5As shown in this embodiment of the utility model, the workpiece feeding mechanism 2 includes a storage rack 21 and a first gripping component 22. Through their coordinated operation, continuous feeding and automatic gripping of workpieces can be achieved, thereby improving feeding efficiency and stability. The storage rack 21 is installed on the first workbench 1 and has storage plates 211 and guide plates 212 arranged at intervals. The guide plates 212 are located above the storage plates 211 and are used for distributing and guiding the workpieces. The storage rack 21 is provided with a guide rail plate 213, and a first cylinder 214 is provided on the guide rail plate 213. The telescopic end of cylinder 214 is connected to a slide plate 215. The slide plate 215 has a top plate 216 that connects the end of the storage plate 211 and the head of the guide plate 212. It is used to push the workpiece located at the end of the storage plate 211 to the head of the guide plate 212, thereby achieving a smooth transition and transfer. The guide plate 213 is also provided with a second cylinder 217. The telescopic end of the second cylinder 217 is connected to a support block 218. The support block 218 is located at the end of the guide plate 212 and is used to push the workpiece located at the end of the storage plate 211 to the head of the guide plate 212, thereby achieving a smooth transition and transfer.

[0055] The first gripping component 22 is slidably disposed on the first worktable 1 and cooperates with the second cylinder 217 and / or the oil seal cover feeding mechanism 3 to remove the workpiece; wherein, the first gripping component 22 includes a first lead screw slide 221 slidably disposed on the first worktable 1 along the Y-axis direction, a third cylinder 222 slidably disposed on the first lead screw slide 221 along the Z-axis direction, a rotary cylinder 223 slidably disposed on the extension end of the third cylinder 222 along the X-axis direction, and two first gripping parts 224 slidably disposed opposite or back to back on the rotary cylinder 223.

[0056] During operation, workpieces are stacked sequentially in a horizontally spaced manner on the storage plate 211 of the storage rack 21. The workpieces to be processed slide to the end of the storage plate 211 under their own weight, and the guide plate 212 above them guides and limits the movement of the workpieces. Then, the first cylinder 214 is activated, and its telescopic end pushes the slide plate 215 to move along the guide rail plate 213. The top plate 216 on the slide plate 215 pushes the workpiece located at the end of the storage plate 211 from the storage plate 211 to the head of the guide plate 212. The workpiece slides to the end of the guide plate 212 under its own weight, thus completing the initial transfer of the workpiece. Then, the second cylinder 217 is activated, and its telescopic end drives the support block 218 to move downward. The workpiece at the end of the guide plate 212 falls onto the support block 218. Subsequently, the telescopic end drives the support block 218 to move upward to above the end of the guide plate 212 to limit the falling of excess workpieces and maintain a stable state, while ensuring the accurate positioning of the workpiece. At this time, the first gripping assembly 22 is activated, and the two first gripping parts 224 move to the position of the workpiece to be gripped under the drive of the first lead screw slide 221. Then, the third cylinder 222 extends downward along the Z-axis, driving the connected rotary cylinder 223 to adjust the gripping angle to the designated position; the two first gripping parts 224 slide relative to each other to clamp the workpiece, completing the gripping action. Subsequently, the third cylinder 222 retracts, the rotary cylinder 223 adjusts the angle, and the gripping assembly moves along the X / Y axis, smoothly transferring the workpiece to the next station, namely the oil seal cover loading mechanism 3, completing the loading task. After the first gripping assembly 22 completes the transfer, it returns to the initial position, waiting for the next loading signal. At this time, the first cylinder 214 and / or the second cylinder 217 cycle through the operation to prepare for the next workpiece.

[0057] Specifically, such as Figure 3 and Figure 6 As shown in the embodiment of this utility model, the oil seal cover feeding mechanism 3, the oil seal feeding mechanism 4, the guide feeding mechanism 5, and the spring feeding mechanism 6 all include a second gripping assembly 11. The second gripping assembly 11 is slidably disposed on the first worktable 1 and cooperates with the annular conveyor line 13 to place the corresponding component on the workpiece. The second gripping assembly 11 includes a second lead screw slide 111 slidably disposed on the first worktable 1 along the Y-axis direction, a first finger cylinder 112 slidably disposed on the second lead screw slide 111 along the Z-axis direction, and two second gripping parts 113 slidably disposed opposite or back to back on the first finger cylinder 112.

[0058] During operation, the second gripping assembly 11 slides along the Y-axis to the hopper position. At this time, the first finger cylinder 112, mounted on the second lead screw slide 111, moves downward along the Z-axis to above the component under the drive of the second lead screw slide 111. Then, the two second gripping parts 113 of the first finger cylinder 112 slide towards each other, clamping the corresponding component, and then retract upwards to achieve component gripping. The second gripping assembly 11 moves along the Y-axis to the position of the corresponding workpiece (i.e., above the workpiece to be assembled on the circular conveyor line 13), ready to place the component. Then, the first finger cylinder 112 descends again along the Z-axis to a preset height, and the second gripping parts 113 release, completing the precise placement of the component. After this process is completed, the first finger cylinder 112 rises, and the gripping assembly returns to its initial position, waiting for the next cycle. Each feeding mechanism operates automatically according to a predetermined sequence and rhythm, sequentially completing the picking and installation of each component, coordinating with the transmission rhythm of the circular conveyor line 13 to achieve continuous automated assembly. In this process, each component (oil seal cover, oil seal, guide, spring) of the aforementioned mechanism is pre-loaded into the corresponding hopper or storage device, ready for the second gripping assembly 11 to pick up the material.

[0059] Specifically, such as Figure 7-10 As shown in the embodiment of this utility model, the nut tightening mechanism 8 includes a first mounting frame 81 disposed on the second workbench 7, a rotary telescopic cylinder 82 slidably disposed on the first mounting frame 81 along the Z-axis direction, a first locking plate 83, and a fourth cylinder 84 disposed on the first mounting frame 81. The telescopic end of the fourth cylinder 84 is connected to two first clamping blocks 86 that are slidably disposed on the first locking plate 83 in opposite or opposite directions through a first connecting rod 85. By using the rotary telescopic cylinder 82 to clamp the first clamping blocks 86, the automatic positioning, clamping and tightening of the nut can be achieved. The whole process does not require manual intervention and effectively reduces labor costs.

[0060] The workpiece to be tightened is conveyed by conveyor belt 12 to turntable 71 on the second workbench 7. Turntable 71 rotates to the nut tightening position and stops, completing the positioning. Then, the fourth cylinder 84 actuates, its telescopic end pushing the first connecting rod 85, causing the two first clamping blocks 86 mounted on the first locking plate 83 to slide inward relative to each other, clamping the workpiece and preventing displacement or loosening during rotation. Next, the rotary telescopic cylinder 82 presses down along the Z-axis to the nut position, extends and begins to rotate, driving the connected rotary head (which can be equipped with a special sleeve) to tighten the nut. After the set torque is reached, the rotary telescopic cylinder 82 stops rotating and retracts, while the first clamping blocks 86 open under the reverse drive of the fourth cylinder 84, releasing the workpiece. Then, turntable 71 rotates to the next station (riveting station) to enter the next process.

[0061] Specifically, such as Figure 7-10As shown in this embodiment of the present invention, the riveting mechanism 9 includes a second mounting frame 91 disposed on the second workbench 7, a riveting machine 92 slidably disposed on the second mounting frame 91 along the Z-axis direction, a second locking plate 93, and a fifth cylinder 94 disposed on the second mounting frame 91. The telescopic end of the fifth cylinder 94 is connected to two second clamping blocks 96 that are slidably disposed on the second locking plate 93 in opposite or opposite directions through a second connecting rod 95. Through the coordinated action of the fifth cylinder 94 and the riveting machine 92, the entire clamping and riveting process is automated, which significantly improves the riveting efficiency and consistency.

[0062] Turntable 71 rotates the workpiece with the nut tightened to the riveting station. Then, the fifth cylinder 94 actuates, driving the second connecting rod 95 to push the two second clamping blocks 96 to slide towards each other, clamping and positioning the workpiece at the riveting point. Next, the riveting machine 92 presses down along the Z-axis to the riveting point of the workpiece, simultaneously initiating a combined rotation and downward pressure action to rivet the top of the target component, preventing the nut from coming out. After completing the riveting action, the riveting machine 92 rises back, and the second clamping blocks 96 open under the reverse drive of the fifth cylinder 94, releasing the workpiece. Subsequently, turntable 71 continues to rotate, sending the workpiece to the unloading station, thus completing the riveting process in the entire automated assembly process.

[0063] Based on the above solutions, such as Figure 11 As shown in this embodiment of the present invention, a third gripping component 72 is slidably provided at the opposite ends of the first workbench 1 and the second workbench 7. The third gripping component 72 cooperates with the conveyor belt 12 to transport the workpiece conveyed by the circular conveyor line 13 to the conveyor belt 12 and / or to transport the workpiece of the conveyor belt 12 to the turntable 71. Specifically, the third gripping component 72 includes a third lead screw slide 721 slidably disposed on the first workbench 1 / first workbench 1 along the X-axis direction, a second finger cylinder 722 slidably disposed on the third lead screw slide 721 along the Z-axis direction, and two third gripping parts 723 slidably disposed opposite or back to back on the second finger cylinder 722. The third gripping component 72 connects the circular conveyor line 13, the conveyor belt 12 and the turntable 71, avoiding manual handling and improving the automation level of the system.

[0064] Based on the above solutions, such as Figure 7-9As shown in this embodiment of the invention, the turntable 71 is provided with a plurality of movable clamping blocks 73. These movable clamping blocks 73 are arranged circumferentially on the turntable 71 and cooperate with the third gripping assembly 72 and / or the nut tightening mechanism 8 and / or the riveting mechanism 9 and / or the unloading mechanism 10. The third gripping assembly 72 on the second worktable 7 places the workpiece conveyed by the conveyor belt 12 onto the movable clamping blocks 73 on the turntable 71, clamping it. Then, the turntable 71 rotates in a step-by-step manner at intervals, sequentially sending the workpiece to the nut tightening station, the riveting station, and the unloading station. At each station, the movable clamping blocks 73 maintain a stable clamping state on the workpiece to ensure that the workpiece does not shift when subsequent mechanisms (such as the rotary telescopic cylinder 82, the riveting machine 92) perform tightening, riveting, or other actions. The movable clamping blocks 73 release after the turntable 71 rotates to the unloading station, cooperating with the unloading mechanism 10 to complete the unloading operation of the finished product.

[0065] Specifically, such as Figure 7 As shown in this embodiment of the invention, the unloading mechanism 10 includes a fourth gripping component 14 slidably disposed on the second worktable 7 and a pallet 15 slidably disposed on the second worktable 7 along the Y-axis. The fourth gripping component 14 includes a fourth lead screw slide 141 slidably disposed on the second worktable 7 along the X-axis, a third finger cylinder 142 slidably disposed on the fourth lead screw slide 141 along the Z-axis, and two fourth gripping parts 143 slidably disposed opposite or back-to-back on the third finger cylinder 142. Through the cooperation of the fourth gripping component 14 and the pallet 15, the entire machine can automatically complete the final unloading process without manual intervention. At the same time, the pallet 15 is provided with a plurality of placement slots, which are arranged in a rectangular array on the pallet 15. The fourth gripping component 14, according to the program control, grips one workpiece at a time and accurately places it into an empty placement slot.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
