Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3, an automated device 10 for nut installation according to the present application comprises: an electric cabinet 11 and an operation box 12. The operation box 12 is provided with: a socket wrench 13, a drive gear assembly 14, and a drive motor 145. The socket wrench 13 is configured to be sleeved on the periphery of the nut 100 to drive the nut 100 to rotate, the driving gear assembly 14 drives the socket wrench 13 to rotate automatically when rotating, and the driving gear assembly 14 is driven to rotate by the driving motor 145. A controller is arranged in the electric cabinet 11. The driving motor 145 is installed in the console box 12 and is communicatively connected to the controller so that the driving motor 145 can be controlled to start or stop by the controller.

In particular, a socket wrench 13 is rotatably connected to the operation box 12. The drive gear assembly 14 includes: a driving wheel 141, two driving wheels 143 and a driven wheel 142. The driving pulley 141 is fixedly connected to the driving motor 145, the two driving pulleys 143 are rotatably connected to the wall of the operation box 12 and are engaged with the driving pulley 141, and the driven pulley 142 is rotatably connected to the operation box 12 and is engaged with the two driving pulleys 143. Socket wrench 13 is fixedly connected to driven wheel 142. Thus, when the nut 100 is fastened, the socket wrench 13 is sleeved on the periphery of the nut 100, and then the controller controls the driving motor 145 to rotate, the driving motor 145 drives the two driving wheels 143 to rotate simultaneously, the two driving wheels 143 drive the driven wheel 142 to rotate simultaneously on two sides of the driven wheel 142, and the driven wheel 142 drives the socket wrench 13 to rotate when rotating, so that the nut 100 is fastened. Here, two driving wheels 143 are driven by one driving wheel 141, and the driven wheels 142 are driven from both sides of the driven wheels 142 by the two driving wheels 143, so that multi-stage transmission is adopted, energy consumption is saved, and the driving structure is stable.

Further, the socket wrench 13 is formed with a visible opening 132. The visible opening 132 is used to allow the conduit 200 from which one end of the nut 100 extends to enter the socket 13. That is, the nut 100 is generally a mounting nut 100 for a low-speed vehicle, the nut 100 has a hollow structure, and the conduit 200 may protrude from the hollow of the nut 100. When the socket wrench 13 is fitted around the nut 100, the conduit 200 is longer and cannot be fitted well. In this scheme, set up a visual opening 132 with box nut 100, when the nut 100 was established to the cover, directly with the spool 200 through this visual opening 132 put into box spanner 13's sleeve can, then directly overlap box spanner 13 in the periphery of nut 100, convenient to use, the operation is quick.

Therefore, the automatic nut mounting device 10 drives the socket wrench 13 to automatically fasten the nut 100 through the driving motor 145 and the driving wheel, so that the nut 100 fastening efficiency is improved, the time of workers is saved, and the labor intensity of the workers is reduced.

As a further alternative, a photoelectric sensor 16 is also provided in the operation box 12. The photoelectric sensor 16 is connected to the controller in a communication manner, and sends information to the controller when the light sensing is interrupted, and the controller controls the driving motor 145 to rotate according to the received information, so as to drive the socket wrench 13 to rotate for resetting until the visible opening 132 faces upwards. At this time, just after the photosensor 16 returns to sensing light, the photosensor 16 sends information to the controller, and the controller controls the driving motor 145 to stop rotating according to the received information. By this arrangement, no matter what position the socket wrench 13 is rotated after the nut 100 is fastened, that is, no matter what position the visible opening 132 is rotated, the socket wrench 13 can be controlled by the controller to rotate to the position where the visible opening 132 faces upward by the light-sensitive sensing of the photoelectric sensor 16. That is, when the visible opening 132 of the socket wrench 13 is facing upward during installation, the photoelectric sensor 16 is just in a light-sensing state. This facilitates the placement of the conduit 200 and the fitting of the nut 100, and further improves the efficiency and reliability of fastening the nut 100.

As a specific embodiment, the outside of the operation box is provided with a start switch 21, and the start switch 21 is electrically connected to the controller. The user sends an instruction to the controller by pressing the start switch 21, and then the controller sends an instruction to the driving motor 145 to control the driving motor 145 to rotate, thereby achieving tightening of the nut 100. When the nut 100 is fastened in place, the user releases the start switch 21, and the start switch 21 stops outputting the driving command. At this time: if the light sensing of the photoelectric sensor 16 is interrupted, a driving instruction is sent to the controller to control the driving motor 145 to perform reset rotation; if the photosensor 16 is in a light-sensitive state, the controller stops sending the command, and the driving motor 145 stops rotating. With this arrangement, the socket wrench 13 can be automatically reset.

In a specific embodiment, the wall of the operation box 12 is formed with a through hole 121, and the photoelectric sensor 16 is detachably mounted on the outside of the operation box 12 with one end thereof inserted into the through hole 121. This facilitates mounting and dismounting of the photosensor 16.

In a specific embodiment, a turntable 17 is further provided in the operation box 12. The rotary plate 17 is used for triggering the photoelectric sensor 16 to control the driving motor 145 to rotate. Specifically, the turntable 17 is rotatably connected between the transceivers of the photosensors 16, and is formed with a notch 171. The notch 171 is used for light sensing between the transceivers. That is, when the viewing opening 132 is facing upward, the notch 171 is located between the transceivers of the photosensor 16, i.e., the photosensor 16 is in a light-sensing state. Specifically, the rotary table 17 is rotatably connected to the wall of the operation box 12, and a return gear 18 is fixed on the rotary table 17. When the turntable 17 rotates to turn off the light induction between the transceivers, the trigger controller controls the driving motor 145 to rotate to drive the reset gear 18 until the notch 171 is driven to rotate to be positioned between the transceivers, and the light induction between the transceivers is restored again. The reset gear 18 is engaged with one of the two transmission wheels 143. That is, when the driving motor 145 rotates the socket wrench 13, the reset gear 18 is rotated synchronously with the driving pulley 143. After the start switch 21 is stopped being pressed, if the reset gear 18 drives the rotating disc 17 to rotate until the transceivers of the photoelectric sensor 16 are separated by the rotating disc 17, the photoelectric sensor 16 triggers the controller to control the driving motor 145 to rotate until the reset gear 18 is driven to drive the notch 171 to rotate until the transceivers are positioned between the transceivers, the controller controls the driving motor 145 to stop rotating, at this time, the notch 171 rotates until the transceivers are positioned between the transceivers, and the socket wrench 13 resets until the visible opening 132 is upward. The linked rotation of the rotary table 17 and the socket wrench 13 is realized through the reset gear 18, so that the reset of the socket wrench 13 is more timely and accurate.

Further, an activation switch 21 is provided on the outside of the operation box 12. The start switch 21 is pressed by a user to control the driving motor 145 to rotate, so as to drive the socket wrench 13 to tighten the nut. The start switch 21 is communicatively connected to the controller to control the drive motor 145 via the controller. Specifically, the start switch 21 is provided beside the socket 13, that is, the socket 13 is mounted on the wall of the operation box 12 on which side, and the start switch 21 is mounted on which side of the operation box 12.

As a specific embodiment, the driven wheel 142 is rotatably connected to the wall of the console box 12 by a coaxial copper bush 19. The coaxial copper sleeve 19 and the driven wheel 142 together form an opening 20. The viewing opening 132 coincides with the opening 20. That is, the viewing opening 132 and the opening 20 are rotated synchronously and are both upward during resetting, which ensures the effectiveness of the conduit 200 being placed into the socket 13.

In a specific embodiment, the inner wall of the operation box 12 is detachably mounted with a mounting box 22, and the two transmission wheels 143 and the coaxial copper bush 19 are rotatably connected to the inside of the mounting box 22. This enables the drive gear assembly 14 to be integrally mounted or dismounted via the mounting case 22, improving mounting efficiency and mounting accuracy.

Specifically, a through groove 221 and a mounting hole 222 are formed in the upper side of the mounting case 22, and the through groove 221 communicates with the mounting hole 222. The through slot 221 is used for the conduit 200 from which one end of the nut 100 extends to enter the socket wrench 13, and the mounting hole 222 is used for rotatably mounting the coaxial copper bush 19. When the visual opening 132 is repositioned, the visual opening 132, the opening 20 and the through slot 221 are coincident.

As a specific embodiment, the installation case 22 includes: a first mounting plate 223, a second mounting plate 224 and a third mounting plate 225 connected in series. The coaxial copper bush 19 includes: a first copper sleeve 191 and a second copper sleeve 192. The first mounting plate 223, the second mounting plate 224, and the third mounting plate 225 are collectively formed with the through groove 221 and the mounting hole 222. The second mounting plate 114 is also formed with a mounting space for mounting the driving wheel 143 and the driving wheel 141. The first copper bush 191 and the second copper bush 192 are rotatably connected to the mounting holes 222 formed in the first mounting plate 223 and the third mounting plate 225, respectively; driven wheel 142 is positioned within mounting hole 222 formed in second mounting plate 224. The driven wheel 1421 is rotatably supported by the first copper bush 191 and the second copper bush 192 from both sides of the driven wheel 142, so that the rotating structure is more stable, and meanwhile, the first mounting plate 223, the second mounting plate 224 and the third mounting plate 225 form one mounting box 22, so that when the mounting box is mounted or dismounted, only the first mounting plate 223, the second mounting plate 224 or the third mounting plate 225 needs to be dismounted.

Further, the first copper sleeve 191, the driven wheel 142 and the second copper sleeve 192 are sleeved on the outer periphery of the socket wrench 13 together. The axes of rotation of the driven wheel 142, the coaxial copper bush 19 and the socket wrench 13 coincide. Thus, the rotation precision of the socket wrench 13 can be ensured, and the situation that the rotation of the socket wrench 13 is delayed can be avoided.

Further, driven wheel 142 is formed with a coaxial sleeve 1421. The coaxial sleeve 1421 is sleeved on the outer periphery of the socket wrench 13, the coaxial copper sleeve 19 is sleeved on the outer periphery of the coaxial sleeve 1421, and at this time, the first copper sleeve 191 and the second copper sleeve 192 are sleeved on the outer periphery of the coaxial sleeve 1421 and located on two sides of the driven wheel 142. The socket wrench 13, the driven wheel 142 and the coaxial copper bush 19 form a stable rotating body through the coaxial bush 1421, so that the rotating precision is effectively improved, and the installation is more convenient. Specifically, the inner wall of the coaxial sleeve 1421 is formed with spline grooves, and the socket wrench 13 is fixed to the coaxial sleeve 1421 by interference-press-fitting of the splines 131 into the spline grooves. Thus, the socket wrench 13 is fixed into the coaxial sleeve 1421 by interference fit of the spline 131, and such a mounting structure is high in mounting accuracy and simple in assembly.

In a specific embodiment, a mounting plate 23 is fixed above the operation box 12, an operation gap 24 is formed between the mounting plate 23 and the operation box 12, the upper end of the mounting box 22 extends out of the operation box 12 from the operation gap 24, and the socket wrench 13 is mounted on the upper end of the mounting box 22 extending out of the operation box 12. This allows the socket wrench 13 to be positioned in a position where it can be seen by the user, facilitating observation of the operating conditions of the fastening nut 100. The electric cabinet 11 is fixed above the mounting plate 23. The electric cabinet is provided with a main switch 25. The main switch 25 can control the on/off of the whole automatic device 10 for nut installation, that is, after the main switch 25 is turned off, the controller cannot receive and send instructions, and thus cannot control the driving motor.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
