[0002] The main uses of a buffer are to buffer load impacts in machinery and equipment, avoid collision damage, eliminate noise, increase the cycle speed, improve product quality, etc.; among them, the buffer consists of a buffer base, pulleys, sliders, oil cylinders, and springs. In the assembly process of the buffer, after sequentially installing the pulleys, sliders, oil cylinders, and springs onto the buffer base, the assembly of the buffer can be completed.

[0003] In the assembly process of the pulley, by assembling the pulley on the positioning post of the buffer base (as Figure 5 shown), the assembly of the pulley is completed, and then the subsequent assembly processes of the slider, oil cylinder, and spring can be carried out.

[0004] The existing pulley assembly mechanism continuously conveys the pulleys through a vibrating bowl, and then installs the pulleys transported to the designated position onto the positioning posts of the buffer base one by one by means of individual handling; however, the pulleys are arranged side by side during the conveying process. During the process of lifting the pulley placed at the designated position, due to the continuous conveying of the pulleys, it may cause the next pulley to be detached from the vibrating bowl, affecting the subsequent conveying effect of the pulleys and the assembly efficiency of the buffer. Therefore, a buffer pulley assembly mechanism is provided to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a buffer pulley assembly mechanism for the deficiencies of the existing technology, so as to solve the technical problem that when lifting the pulley placed at the designated position by the existing pulley assembly mechanism, the next pulley may be detached from the vibrating bowl.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A buffer pulley assembly mechanism includes a machine table and a turntable horizontally and rotatably arranged on the machine table. The turntable rotates intermittently, and a number of assembly position jigs are arranged in an array around its rotation center point; the machine table is equipped with a vibrating bowl for continuously conveying the pulleys and a linear feeding part. The initial end of the linear feeding part is connected to the discharge port of the vibrating bowl, and the end of the linear feeding part is equipped with a translation misalignment component for individually driving the pulley to translate a specified distance. The machine table is also provided with a handling component for transporting the pulley translated a specified distance to the positioning post of the buffer base for assembly.

[0008] Further, the machine table is equipped with an intermittent driving component, and the turntable is installed on the intermittent driving component.

[0009] Furthermore, the translational dislocation component includes a fixed plate and a fixed block arranged on the fixed plate, the fixed block is formed with a material guide groove connected to the end of the linear feeding part, a movable block is horizontally movably provided on the fixed block, and the movable direction of the movable block is perpendicular to the conveying direction of the linear feeding part, and a material trough for receiving the conveyed pulley and which can only accommodate one pulley is formed on the movable block; the end of the movable track of the material trough is a grabbing position for the transport component to grab the pulley.

[0010] Furthermore, a third cylinder is mounted on the fixed plate, and the telescopic direction of the telescopic rod is consistent with the sliding direction of the movable block, and the end of the telescopic rod of the third cylinder is fixedly arranged with the movable block.

[0011] Furthermore, the transport component includes a fixed seat and a movable frame which is laterally movably arranged on the fixed seat, the movable frame is equipped with a vertically arranged slide rail, and a lifting plate is slidably provided on the slide rail, the lifting plate is equipped with a clamping cylinder with an execution end arranged downward, and clamping blocks for clamping a pulley placed at the material grabbing position are installed on both execution ends of the clamping cylinder.

[0012] Furthermore, the fixed seat is equipped with a first cylinder arranged transversely, and the end of the telescopic rod of the first cylinder is fixedly arranged on the movable frame.

[0013] Furthermore, the movable frame is equipped with a second cylinder with a telescopic rod arranged upward, the initial state of the telescopic rod of the second cylinder is an extended state, and the end of the telescopic rod is fixed to the lifting plate.

[0014] Furthermore, the fixed block is formed with a clearance groove which is placed beside the material grabbing position and is used to provide a clamping position for the clamping block, and the groove bottom of the clearance groove is higher than the groove bottom of the material containing groove.

[0015] Furthermore, the machine is provided with an oiling component for oiling the pulley mounted on the positioning column.

[0016] Furthermore, the oil injection component includes a supporting column and an adjusting block arranged on the supporting column, a fourth cylinder is rotatably provided on the adjusting block, and a mounting plate is provided on the end of the telescopic rod of the fourth cylinder, and an oil injection device for oiling the pulley installed on the positioning column is installed on the mounting plate.

[0017] The beneficial effects of the utility model are as follows: when loading materials, the drive turntable is rotated intermittently, and the assembly fixture with the buffer base is driven to the end of the conveying track of the conveying component and then stops rotating. During the rotation of the turntable, the vibration plate is operated to continuously convey the pulley to the linear feeding part, so that multiple pulleys are conveyed along a straight line on the linear feeding part to convey the first pulley to the translational dislocation component, and then the translational dislocation component is operated to translate the pulley a specified distance, so that the first pulley is dislocated with the next pulley, and the pulley after the translational dislocation is placed in the grabbing position of the conveying component, and finally the conveying component is operated to convey the pulley after the translational dislocation to the positioning column of the buffer base for assembly processing.

[0018] A translational dislocation component is set to drive a pulley to translate a specified distance so that it is dislocated with the next pulley. Its purpose is to provide a position for the handling component to clamp the pulley to prevent the handling component from causing the next pulley to separate from the linear feeding part when lifting the first pulley. With the action of the translational dislocation component, the accuracy of the handling component in handling the pulley and the efficiency of the pulley and the buffer base are greatly improved.

[0026] The following combines the accompanying drawings to describe in detail a buffer pulley assembly mechanism of the present utility model.

[0027] As Figure 1 shown, an embodiment of a buffer pulley assembly mechanism of the present utility model includes a machine table 102 and a turntable 103 horizontally rotatably arranged on the machine table 102. The turntable 103 rotates intermittently, and a plurality of assembly fixtures 105 arranged in an array around its rotation center point are installed on the turntable 103. The assembly fixture 105 is a working station for assembling the buffer. The turntable 103 drives the assembly fixture 105 to rotate intermittently and cooperates with other feeding mechanisms for feeding buffer components, and sequentially places the various components of the buffer on the same assembly fixture 105 according to the assembly process for assembly processing.

[0028] In order to enable the turntable 103 to perform intermittent rotation automatically on the machine table 102, the machine table 102 is equipped with an intermittent driving component 104, and the turntable 103 is installed on the intermittent driving component 104. By operating the intermittent driving component 104, the turntable 103 is driven to perform intermittent rotation. Specifically, when the turntable 103 rotates to drive one of the assembly position jigs 105 to align with the buffer base feeding mechanism (not shown in the figure), the buffer base feeding mechanism is operated to feed the buffer base 1001 onto the assembly position jig 105. Subsequently, the turntable 103 is driven to rotate again, and the assembly position jig 105 with the buffer base 1001 placed thereon is rotated to align with the pulley 1003 feeding position. At the same time, the next assembly position jig 105 without the buffer base 1001 placed thereon is driven to align with the buffer base feeding mechanism (not shown in the figure). Then, the pulley assembly mechanism is operated to feed and install the pulley 1003 onto the positioning post 1002 of the buffer base 1001. And the buffer base feeding mechanism (not shown in the figure) and the pulley assembly mechanism can operate simultaneously. While feeding the buffer base 1001 onto the assembly position jig 105, the pulley 1003 is fed and installed onto the positioning post 1002 of the buffer base 1001. Then, the turntable 103 is driven to rotate, and the buffer base 1001 with the pulley 1003 installed thereon is driven to align with the feeding mechanism for installing other components of the buffer to perform the next assembly of the buffer. The intermittent driving component 104 is a prior art. In practice, a servo motor assembly can be adopted, or a structure such as a missing gear driving a full gear for intermittent rotation that can drive the turntable 103 to perform intermittent rotation can be used, which will not be elaborated here.

[0029] During the assembly process of the pulley 1003 and the buffer base 1001, in order to achieve automatic and intermittent assembly processing of the pulley 1003, a vibrating bowl 31 (model BF-20 can be used) for continuously conveying the pulley 1003 and a linear feeding part 33 are installed on the machine table 102. The machine table 102 is provided with a support base 32 for supporting the linear feeding part 33, and the initial end of the linear feeding part 33 is connected to the discharge port of the vibrating bowl 31. By operating the vibrating bowl 31, the pulley 1003 is conveyed onto the linear feeding part 33, so that multiple pulleys 1003 are conveyed linearly on the linear feeding part 33. The vibrating bowl 31 and the linear feeding part 33 are both prior arts and will not be elaborated here. A translation misalignment component 34 for driving each pulley 1003 to translate a specified distance is installed at the end of the linear feeding part 33, and a handling component 35 for handling the pulley 1003 that has translated the specified distance onto the positioning post 1002 of the buffer base 1001 for assembly is also provided on the machine table 102. Operate the intermittent drive component 104 to drive the turntable 103 to rotate intermittently. After the turntable 103 with the assembly position fixture 105 placed with the buffer base 1001 stops rotating at the end of the handling trajectory of the handling component 35, during the rotation of the turntable 103, first operate the translation misalignment component 34 to translate the first pulley 1003 conveyed by the linear feeding part 33 a specified distance, so that the first pulley 1003 is misaligned with the next pulley 1003. The misaligned pulley 1003 is placed at the grasping position of the handling component 35, and finally operate the handling component 35 to handle the misaligned pulley 1003 onto the positioning post 1002 of the buffer base 1001 for assembly processing.

[0030] The translation misalignment component 34 is set to drive a pulley 1003 to translate a specified distance to misalign it with the next pulley 1003. The purpose is to provide a position for the handling component 35 to clamp the pulley 1003. And, a ring-shaped groove is provided on the circumferential side of the pulley 1003 (as Figure 5 shown). If the pulleys 1003 are placed side by side, during the process of the handling component 35 lifting the first pulley 1003, the next pulley 1003 may get stuck in the ring-shaped groove, thus causing the next pulley 1003 to be detached from the linear feeding part 33, affecting the subsequent conveying effect of the pulley 1003 and the assembly efficiency of the buffer.

[0031] In addition, the machine table 102 is also provided with an oil injection component 36 for injecting oil into the pulley 1003 installed on the positioning post 1002. After assembling the buffer base 1001 and the pulley 1003, operate the oil injection component 36 to inject lubricating oil (or lubricant) into the hinge joint between the pulley 1003 and the positioning post 1002 to lubricate the pulley 1003.

[0032] As Figures 2-3As shown in the figure, the translation misalignment component 34 includes a fixed plate 341 and a fixed block 342 arranged on the fixed plate 341. The fixed block 342 is formed with a material guiding groove 343 connected to the end of the linear feeding part 33. A movable block 344 is horizontally movably arranged on the fixed block 342, and the moving direction of the movable block 344 is perpendicular to the conveying direction of the linear feeding part 33. A material receiving groove 345 for receiving the conveyed pulley 1003 and capable of accommodating only one pulley 1003 is formed on the movable block 344; the initial position of the material receiving groove 345 is connected to the material guiding groove 343. The linear feeding part 33 linearly conveys a plurality of pulleys 1003, so that the first pulley 1003 is guided into the material receiving groove 345 through the material guiding groove 343, and the next pulley 1003 is placed in the material guiding groove 343. Finally, the movable block 344 is controlled to slide horizontally on the fixed block 342, so as to drive the pulley 1003 placed in the material receiving groove 345 to move horizontally; in addition, the end of the moving track of the material receiving groove 345 is a material grasping position 346 for the handling component 35 to grasp the pulley 1003. By controlling the movable block 344 to slide on the fixed block 342, the pulley 1003 placed in the material receiving groove 345 is driven to move to the material grasping position 346 for the handling component 35 to grasp and carry; after the handling component 35 carries away the pulley 1003, the movable block 344 is controlled to reset. After the material receiving groove 345 is reset and reconnected to the material guiding groove 343, the material receiving groove 345 can receive the next pulley 1003.

[0033] Additionally, a third air cylinder 348 with a telescopic rod whose telescopic direction is consistent with the sliding direction of the movable block 344 is installed on the fixed plate 341, and the end of the telescopic rod of the third air cylinder 348 is fixedly arranged with the movable block 344; when the telescopic rod of the third air cylinder 348 is in the extended state, the material receiving groove 345 on the movable block 344 is connected to the material guiding groove 343, and the material receiving groove 345 can receive a pulley 1003. After a pulley 1003 is placed in the material receiving groove 345, the third air cylinder 348 is operated, and the telescopic rod contracts to pull the movable block 344 to slide on the fixed block 342, so as to drive the pulley 1003 to move to the material grasping position 346, and then the handling component 35 is operated to grasp it.

[0034] In addition, an installation block 349 is further arranged on the fixed block 342, and an inductor 3410 is arranged on the installation block 349. The inductor 3410 is used to sense whether a pulley 1003 is placed on the material receiving groove 345. After detecting a pulley 1003, the third air cylinder 348 can be operated, so as to pull the movable block 344 to slide on the fixed block 342.

[0035] Such as Figure 2As shown in the figure, the handling component 35 includes a fixed seat 351 and a movable frame 352 that is horizontally movably arranged on the fixed seat 351. The fixed seat 351 is provided with a horizontally arranged first cylinder 353, and the end of the telescopic rod of the first cylinder 353 is fixedly arranged with the movable frame 352. By operating the first cylinder 353, the movable frame 352 can be controlled to move horizontally on the fixed seat 351. Among them, the movable frame 352 is provided with a vertically arranged slide rail 354, and a lifting plate 355 is slidably arranged on the slide rail 354. Under the action of the slide rail 354, the lifting plate 355 moves up and down on the movable frame 352. In addition, the movable frame 352 is also provided with a second cylinder 356 with its telescopic rod facing upward. The initial state of the telescopic rod of the second cylinder 356 is the extended state, and the end of the telescopic rod is fixedly arranged with the lifting plate 355. By operating the second cylinder 356, the lifting plate 355 can be controlled to move up and down on the movable frame 352. In addition, the lifting plate 355 is provided with a jaw cylinder 357 with its execution end facing downward, and clamping blocks 358 for clamping the pulley 1003 placed at the material grabbing position 346 are arranged on both execution ends of the jaw cylinder 357. By pulling the movable block 344 to slide on the fixed block 342, the pulley 1003 is driven to move to the material grabbing position 346. First, the second cylinder 356 is operated, and the telescopic rod contracts to drive the lifting plate 355 to move downward, thereby driving the jaw cylinder 357 to move downward together. The clamping blocks 358 on both execution ends of the jaw cylinder 357 are respectively placed on both sides of the pulley 1003 at the material grabbing position 346. Then, the jaw cylinder 357 is operated to control the two clamping blocks 358 to move closer to each other to clamp the pulley 1003. Under the action of the second cylinder 356 controlling the lifting plate 355 to move upward and the first cylinder 353 controlling the movable frame 352 to move, the pulley 1003 is transported to the positioning column 1002 of the buffer base 1001 for assembly processing.

[0036] In addition, the fixed block 342 is formed with a relief groove 347 that is located beside the material grabbing position 346 and is used to provide a clamping position for the clamping block 358. The bottom of the relief groove 347 is higher than the bottom of the material receiving groove 345, so that the pulley 1003 to be clamped is limited by the height difference to prevent deviation due to vibration.

[0037] As Figure 4As shown in the figure, the oil injection component 36 includes a support column 361 and an adjustment block 362 provided on the support column 361. A fourth cylinder 363 is rotatably provided on the adjustment block 362, and a mounting plate 364 is provided at the end of the telescopic rod of the fourth cylinder 363. An oil injection device 365 for oil injection treatment of the pulley 1003 mounted on the positioning column 1002 is installed on the mounting plate 364. After the pulley 1003 is installed on the positioning column 1002 of the buffer base 1001 by the handling component 35, first operate the fourth cylinder 363, and the telescopic rod of the fourth cylinder 363 extends, so as to drive the liquid injection end of the oil injection device 365 to the designated liquid injection position, and then start the oil injection device 365 to perform oil injection treatment on the pulley 1003; moreover, the height of the adjustment block 362 on the support column 361 can also be adjusted, and the angle of the fourth cylinder 363 can be rotated to adjust the oil injection position of the oil injection device 365, so as to adapt to buffer installations of different sizes.

[0038] In summary, it can be seen that the present utility model has the excellent characteristics described above, so that it can enhance the efficiency never before achieved in the prior art during use and has practicability, becoming a product with extremely high practical value.

[0039] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
