Description

Technical Field

[0001] The present invention belongs to the field of turning, and specifically relates to a turning device for electric bicycle accessories. Background Art

[0002] Turning is a machining method that removes materials through the rotational movement of the workpiece and the linear or curvilinear movement of the cutting tool, so as to obtain the required shape and size. Turning processing is widely used in mechanical manufacturing and is suitable for processing various rotary parts, such as shaft parts, disc parts, sleeve parts, etc.

[0003] Accessories such as the central shaft of electric vehicles generally need to be processed through a turning device; generally, the rough material is fixed on the turning lathe, and then a series of operations such as end face processing, finish turning, and hole opening are performed on the rough material.

[0004] In the process of machining the axle of an electric vehicle with a traditional turning device, generally, the axle to be turned is fixed, and then the axle to be turned is driven to rotate, and different turning tools are used to machine the axle to be turned. Because a variety of different turning tools are required in the process of axle machining, and drilling and other operations are also required, and the types used are numerous, it is necessary to frequently replace different machining tools, resulting in a reduction in processing efficiency. Moreover, when machining a long axle, in order to ensure processing stability, it is necessary to machine one end of the axle first and then the other end, and it is also impossible to directly use a long axle to be turned to machine multiple short axles, so the functionality and practicability are relatively low.

[0005] Therefore, the present invention provides a turning device for electric bicycle accessories. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A turning device for electric bicycle accessories according to the present invention includes a processing box, a connection box, and a moving box. The connection box is installed between the processing box and the moving box. An electric chuck for fixing the axle to be turned is arranged inside the processing box. A three-jaw chuck capable of moving is arranged behind the electric chuck. A driving motor two for driving the three-jaw chuck to rotate is arranged at the rear end of the three-jaw chuck. A recovery table capable of translating and rotating is arranged inside the processing box. A locking valve for fixing the axle to be turned is provided in the middle of the recovery table. A set of turning tools capable of lifting and a set of lathe drills one are arranged inside the processing box. A set of lathe drills two is arranged at the front end of the recovery table; Fix the end of the shaft to be turned on the three-jaw chuck, move the three-jaw chuck to move the end of the shaft to be turned to the end of the power chuck, drive the three-jaw chuck to rotate by the second driving motor. Then, as the three-jaw chuck continuously moves towards the processing box, when turning with a turning tool is required, each turning tool in a set of turning tools is different and is used to process different shapes according to requirements. Move the entire set of movable turning tools to move the required type of turning tool above the shaft to be turned, and then lower the turning tool to process the shaft to be turned with this turning tool. As the processing progresses, the three-jaw chuck continuously moves forward, pushing the shaft to be turned that has not been processed towards the processing box. During the movement of the shaft to be turned, the required type of turning tool can be moved above the shaft to be turned, and the turning tool can be lowered to process the shaft to be turned. At the same time, the second driving motor can also be stopped to keep the shaft to be turned stationary first. Then, move the second lathe drill bit above the shaft to be turned, adjust the orientation of the shaft to be turned by the second driving motor, and use different first lathe drill bits to drill the surface of the shaft to be turned, etc.; when the shaft to be turned has moved a long distance into the processing box, the recovery table can be moved to align it with the shaft to be turned, insert the end of the shaft to be turned into the locking valve, and the locking valve fixes the end of the shaft to be turned. The locking valve and the recovery table can rotate relative to each other, so at this time, the shaft to be turned can continue to rotate during the processing. At the same time, the recovery table can also cooperate with the movement of the shaft to be turned to ensure the stability of the movement and rotation of the shaft to be turned. After using the locking valve to hold the end of the shaft to be turned, not only can the extended shaft to be turned rotate stably, reducing the processing instability caused by excessive end extension, but also a longer shaft can be processed; at the same time, during the fixing stage of the locking valve, the turning tool can be used to directly cut off the shaft to be turned, and the processed part remains in the locking valve, which not only does not affect subsequent processing, but also the second driving motor does not need to stop working, realizing the continuous processing of a long shaft into multiple short shafts; at the same time, multiple second lathe drill bits at the end of the recovery table can be started individually to drill the shaft to be turned, so synchronous drilling can be carried out, or by adjusting the angle of the recovery table, non-vertical holes can be processed on the surface of the shaft to be turned.

[0008] Preferably, one side of the processing box is open, and an observable cover that can be opened is installed at the opening. The front end of the processing box is set to be flip-openable. Two groups of vertically distributed moving rails are fixedly connected to the inner bottom of the processing box. The moving end of the upper moving rail is connected to the recovery table. The middle part of the observable cover is made of transparent material, and the internal situation can be directly observed from the outside. Opening the front end of the processing box can be used to install the shaft to be turned. The two groups of vertically distributed moving rails can drive the recovery table to move horizontally in any direction.

[0009] Preferably, a servo motor for driving the recycling table to rotate is installed between the recycling table and the mobile end of the mobile rail. An electric ring is rotatably connected to the outer side of the locking valve end. A plurality of second lathe drills are arranged at equal intervals in a ring shape on the outer side of the electric ring. The servo motor can drive the recycling table to rotate horizontally, so that the angle between the second lathe drill and the shaft to be turned can be adjusted, and thus holes with any orientation can be machined on the surface of the shaft to be turned. The rotation of the electric ring can adjust different second lathe drills to face the shaft to be turned, so as to machine different drills.

[0010] Preferably, an electric slide rail one for driving the second driving motor to move is installed at the bottom of the second driving motor. A plurality of rotatable rotating rings are arranged between the three-jaw chuck and the electric chuck. A plurality of electric telescopic rods are fixedly connected to the outer side of the rotating ring. When the shaft to be turned is relatively long, in order to ensure the stability of the shaft to be turned during the initial rotation, the plurality of electric telescopic rods extend to grasp the outer side of the shaft to be turned. During the rotation of the shaft to be turned, the rotating rings rotate synchronously. When the three-jaw chuck moves forward, the rotating rings move forward synchronously. When the rotating ring block touches the electric chuck, the fixation of the electric telescopic rods is released until all the rotating rings are close to each other and all the electric telescopic rods are released from fixation.

[0011] Preferably, a binding collar is rotatably clamped to the outer side of the rotating ring. A third driving motor for driving the rotating ring to rotate is fixedly connected to the inside of the binding collar. A plurality of vertically arranged fixing frames are fixedly connected to the outer side of the binding collar. Both the three-jaw chuck and the second driving motor can pass through the rotating ring. The third driving motor in the binding collar can drive the rotating ring to rotate synchronously with the shaft to be turned. On the one hand, the load of the second driving motor is reduced. On the other hand, when the fixation of the electric telescopic rods is released, first keep the rotating ring rotating, and then shorten the electric telescopic rods to release the fixation. This method is safer and more stable.

[0012] Preferably, two groups of electric slide rails two are arranged above the binding collar. The tops of the plurality of fixing frames of the binding collar are fixedly connected to the mobile ends of the electric slide rails two. The electric slide rails two can drive a plurality of binding collars and the shaft to be turned to move synchronously through the fixing frames. There are a plurality of mobile ends of the electric slide rails two, and all of them can be driven independently. When the first binding collar moves to the end, the electric slide rails two control the binding collar to stop moving. Wait until the subsequent binding collars are close to the previous binding collar, and then stop the subsequent binding collars one by one, so as to realize the stable fixation process of the relatively long shaft to be turned during the movement.

[0013] Preferably, an electric slide rail two for driving the second driving motor to move is installed at the bottom of the second driving motor. The electric slide rail two is located below the restraint collar. The second driving motor is driven to slide by the electric slide rail two. Since the electric slide rail two is located below the restraint collar, the two will not touch each other. After the processing is completed, first the second driving motor returns to its position, and then multiple restraint collars return to their positions driven by the electric slide rail two.

[0014] Preferably, multiple turning tools are arranged in parallel to form a group, and multiple first lathe drills are arranged in parallel to form a group. A group of turning tools and a group of first lathe drills are arranged in parallel. And a moving table capable of lifting and translating is fixedly connected above a group of turning tools and a group of first lathe drills. An electric slide rail three is installed between the moving table and the processing box, so as to control a group of turning tools and a group of first lathe drills to move horizontally, and move the required tools above the shaft to be turned. An electric push rod for driving each turning tool and the first lathe drill to lift separately is arranged in the moving table, so that the tools can be moved to the surface of the shaft to be turned for processing.

[0015] Preferably, a locking disc is rotatably clamped on the outer side of the electric chuck. A first driving motor for driving the electric chuck to rotate is installed inside the locking disc. The end of the electric chuck serves as the reference surface for processing. After the three-jaw chuck moves close to the electric chuck, first the first driving motor drives the electric chuck to rotate and accelerates to the same speed as the shaft to be turned. Then the electric chuck grasps the shaft to be turned. After the shaft to be turned is grasped by the three-jaw chuck, stable processing of the shaft to be turned can be carried out. After the processing is completed, the fixation of the electric chuck is released; the electric chuck can also fix the shaft to be turned alone and drive the shaft to be turned to rotate for processing by the first driving motor.

[0016] Preferably, a matching set is installed at the end of the electric telescopic rod, and a docking sleeve is installed on the outer side of the third driving motor. The radian of the matching set is the same as the radian of the shaft to be turned, ensuring that the end of the electric telescopic rod is firmly fixed to the shaft to be turned. The docking sleeve is provided for multiple restraint collars to fit together when they approach each other.

[0017] The beneficial effects of the present invention are as follows: 1. An electric bicycle accessory turning device according to the present invention, through the setting of a set of turning tools capable of lifting and a set of lathe drills 1, when it is necessary to use the turning tools for turning, each turning tool in the set of turning tools is different and is used to process different shapes according to requirements. The entire set of movable turning tools is moved to move the required type of turning tool above the shaft to be turned, and then the turning tool is lowered to process the shaft to be turned with this turning tool. As the processing progresses, the three-jaw chuck continuously moves forward, pushing the shaft to be turned that has not been processed continuously towards the processing box. During the movement of the shaft to be turned, the required type of turning tool can be moved above the shaft to be turned, and the turning tool can be lowered to process the shaft to be turned. At the same time, the driving motor 2 can also be stopped to keep the shaft to be turned stationary first, and then the lathe drill 2 is moved above the shaft to be turned. The orientation of the shaft to be turned is adjusted through the driving motor 2, and different lathe drills 1 are used to drill the surface of the shaft to be turned, etc. Through this setting, an efficient turning function is realized, and multiple turning tools and the lathe drill 2 can all perform adaptation work, ensuring that during the complex processing of the axle, the required processing tools can be quickly switched, thereby improving the processing efficiency.

[0018] 2. An electric bicycle accessory turning device according to the present invention, when the shaft to be turned moves a relatively long distance into the processing box, the recycling table can be moved to align the recycling table with the shaft to be turned, and the end of the shaft to be turned is inserted into the locking valve. The locking valve fixes the end of the shaft to be turned. The locking valve and the recycling table can rotate relative to each other, so at this time, the shaft to be turned can still continue the rotational processing process, and at the same time, the recycling table can also cooperate with the movement of the shaft to be turned to ensure the stability of the movement and rotation of the shaft to be turned. After using the locking valve to hold the end of the shaft to be turned, not only can the extended shaft to be turned rotate stably, reducing the processing instability caused by excessive end extension, so that a longer axle can be processed; at the same time, during the fixing stage of the locking valve, the turning tool can also be used to directly cut off the shaft to be turned, and the processed part remains in the locking valve, which not only does not affect subsequent processing, but also the driving motor 2 does not need to stop working, realizing the continuous processing of a long shaft into multiple short shafts; at the same time, multiple lathe drills 2 at the end of the recycling table can be started separately to drill the shaft to be turned, so that synchronous drilling can be carried out, or by adjusting the angle of the recycling table, non-vertical holes can be processed on the surface of the shaft to be turned.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] As Figures 1 to 6 shown, a turning device for electric bicycle accessories according to an embodiment of the present invention includes a processing box 1, a connection box 2 and a moving box 3. The connection box 2 is installed between the processing box 1 and the moving box 3. An electric chuck 8 for fixing the shaft to be turned 13 is provided inside the processing box 1. A three-jaw chuck 19 capable of moving is provided behind the electric chuck 8. A drive motor II 20 for driving the three-jaw chuck 19 to rotate is provided at the rear end of the three-jaw chuck 19. A recycling table 5 capable of translating and rotating is provided inside the processing box 1. A locking valve 11 for fixing the shaft to be turned 13 is provided in the middle of the recycling table 5. A set of turning tools 7 capable of lifting and a set of lathe drill bits I 6 are provided inside the processing box 1. A set of lathe drill bits II 10 is provided at the front end of the recycling table 5; Fix the end of the shaft 13 to be turned on the three-jaw chuck 19, move the three-jaw chuck 19 to move the end of the shaft 13 to be turned to the end of the electric chuck 8, drive the three-jaw chuck 19 to rotate by the second driving motor 20. Then, as the three-jaw chuck 19 continuously moves towards the processing box 1, when turning with the turning tool 7 is required, each turning tool 7 in a set of turning tools 7 is different and is used to process different shapes according to requirements. Move the entire set of turning tools 7, move the required type of turning tool 7 above the shaft 13 to be turned, and then lower this turning tool 7 to process the shaft 13 to be turned with this turning tool 7. As the processing progresses, the three-jaw chuck 19 continuously moves forward, pushing the shaft 13 to be turned that has not been processed towards the processing box 1. During the movement of the shaft 13 to be turned, the required type of turning tool 7 can be moved above the shaft 13 to be turned, and the turning tool 7 can be lowered to process the shaft 13 to be turned. At the same time, the second driving motor 20 can also be stopped to keep the shaft 13 to be turned stationary first. Then, move the second lathe drill bit 10 above the shaft 13 to be turned, adjust the orientation of the shaft 13 to be turned through the second driving motor 20, and use different first lathe drill bits 6 to drill the surface of the shaft 13 to be turned, etc.; when the shaft 13 to be turned moves a relatively long distance into the processing box 1, the recovery table 5 can be moved, move the recovery table 5 to align with the shaft 13 to be turned, and insert the end of the shaft 13 to be turned into the locking valve 11. The locking valve 11 fixes the end of the shaft 13 to be turned. The locking valve 11 and the recovery table 5 can rotate relative to each other. Therefore, at this time, the shaft 13 to be turned can still continue the rotary processing process. At the same time, the recovery table 5 can also cooperate with the movement of the shaft 13 to be turned to ensure the stability of the movement and rotation of the shaft 13 to be turned. After grasping the end of the shaft 13 to be turned by using the locking valve 11, not only can the outward-extending shaft 13 to be turned rotate stably, reducing the processing instability caused by excessive end extension, but also a longer axle can be processed in this way; at the same time, during the fixing stage of the locking valve 11, the turning tool 7 can also be used to directly cut off the shaft 13 to be turned, and the processed part remains in the locking valve 11, which not only does not affect the subsequent processing, but also the second driving motor 20 does not need to stop working, realizing the continuous processing of a long shaft into multiple short shafts; at the same time, multiple second lathe drill bits 10 at the end of the recovery table 5 can all be started independently to drill the shaft 13 to be turned, so that synchronous drilling can be carried out, or by adjusting the angle of the recovery table 5, non-vertical holes can be processed on the surface of the shaft 13 to be turned.

[0023] One side of the processing box 1 is open, an observable cover that can be opened is installed at its opening, and the front end of the processing box 1 is set to be turnable and openable. Two groups of vertically distributed moving rails 4 are fixedly connected to the inner bottom of the processing box 1. The moving end of the upper moving rail 4 is connected to the recovery table 5; During operation, the middle part of the observation cover is made of transparent material, allowing the internal situation to be directly observed from the outside. The front end of the processing box 1 can be opened to install the shaft to be turned 13. Two groups of vertically distributed moving rails 4 can drive the recycling table 5 to move horizontally in any direction.

[0024] A servo motor 12 for driving the recycling table 5 to rotate is installed between the recycling table 5 and the moving end of the moving rail 4. An electric ring is rotatably connected to the outside of the end of the locking valve 11. A plurality of lathe drills II 10 are arranged at equal intervals in a ring on the outside of the electric ring; During operation, the servo motor 12 can drive the recycling table 5 to rotate horizontally, so that the angle between the lathe drill II 10 and the shaft to be turned 13 can be adjusted, and thus holes with any orientation can be machined on the surface of the shaft to be turned 13. The rotation of the electric ring can adjust different lathe drills II 10 to face the shaft to be turned 13, thereby machining different drills.

[0025] An electric slide rail I 15 for driving the driving motor II 20 to move is installed at the bottom of the driving motor II 20. A plurality of rotatable rotating rings 24 are arranged between the three-jaw chuck 19 and the electric chuck 8. A plurality of electric telescopic rods 21 are fixedly connected to the outside of the rotating ring 24; During operation, when the shaft to be turned 13 is relatively long, in order to ensure the stability of the shaft to be turned 13 during the initial rotation, the plurality of electric telescopic rods 21 extend to grasp the outside of the shaft to be turned 13. During the rotation of the shaft to be turned 13, the rotating ring 24 rotates synchronously. When the three-jaw chuck 19 moves forward, the rotating ring 24 moves forward synchronously. When the rotating ring 24 is about to contact the electric chuck 8, the fixation of the electric telescopic rods 21 is released until all the rotating rings 24 are close to each other and all the electric telescopic rods 21 are released from fixation.

[0026] A binding collar 16 is rotatably clamped to the outside of the rotating ring 24. A driving motor III 22 for driving the rotating ring 24 to rotate is fixedly connected to the inside of the binding collar 16. A plurality of vertically arranged fixing frames 17 are fixedly connected to the outside of the binding collar 16. Both the three-jaw chuck 19 and the driving motor II 20 can pass through the rotating ring 24; During operation, the driving motor III 22 in the binding collar 16 can drive the rotating ring 24 to rotate synchronously with the shaft to be turned 13. On the one hand, the load of the driving motor II 20 is reduced. On the other hand, when releasing the fixation of the electric telescopic rods 21, first keep the rotation of the rotating ring 24, and then shorten the electric telescopic rods 21 to release the fixation. This method is safer and more stable.

[0027] Two groups of electric slide rails II 18 are arranged above the binding collar 16. The tops of the plurality of fixing frames 17 of the binding collar 16 are fixedly connected to the moving ends of the electric slide rails II 18; During operation, the second electric slide rail 18 can drive a plurality of restraint collars 16 and the shaft to be turned 13 to perform synchronous translation through the fixing frame 17. There are multiple mobile ends of the second electric slide rail 18, and all of them can be driven independently. When the first restraint collar 16 moves to the end, the second electric slide rail 18 controls the restraint collar 16 to stop moving. After the subsequent restraint collars 16 are close to the previous restraint collar 16, the subsequent restraint collars 16 are stopped one by one, thus realizing the stable fixing process of the longer shaft to be turned 13 during the moving process.

[0028] A second electric slide rail 18 for driving the second drive motor 20 to move is installed at the bottom of the second drive motor 20, and the second electric slide rail 18 is located below the restraint collar 16; During operation, the second electric slide rail 18 drives the second drive motor 20 to slide. Since the second electric slide rail 18 is located below the restraint collar 16, the two will not touch each other. After the processing is completed, first the second drive motor 20 returns to its position, and then the plurality of restraint collars 16 return to their positions driven by the second electric slide rail 18.

[0029] A plurality of the turning tools 7 are arranged in parallel to form a group, and a plurality of the first lathe drills 6 are arranged in parallel to form a group. A group of turning tools 7 and a group of the first lathe drills 6 are arranged in parallel, and a moving table 9 capable of lifting and translating is fixedly connected above both a group of turning tools 7 and a group of the first lathe drills 6; During operation, an electric slide rail three is installed between the moving table 9 and the processing box 1, so as to control a group of turning tools 7 and a group of the first lathe drills 6 to perform horizontal movement, move the required tools above the shaft to be turned 13. The moving table 9 is provided with electric push rods for driving each turning tool 7 and the first lathe drill 6 to lift independently, so that the tools can be moved to the surface of the shaft to be turned 13 for processing.

[0030] A locking disk 23 is rotationally clamped on the outside of the electric chuck 8, and a first drive motor 14 for driving the electric chuck 8 to rotate is installed inside the locking disk 23; During operation, the end of the electric chuck 8 serves as the processing reference surface. After the three-jaw chuck 19 moves close to the electric chuck 8, first the first drive motor 14 drives the electric chuck 8 to rotate and accelerates to the same speed as the shaft to be turned 13. Then the electric chuck 8 grabs the shaft to be turned 13. After the shaft to be turned 13 is grabbed by the three-jaw chuck 19, stable processing of the shaft to be turned 13 can be carried out. After the processing is completed, the fixing of the electric chuck 8 is released; the electric chuck 8 can also fix the shaft to be turned 13 alone and drive the shaft to be turned 13 to rotate for processing through the first drive motor 14.

[0031] An adapter is installed at the end of the electric telescopic rod 21, and a docking sleeve is installed outside the third drive motor 22; During operation, the radian of the mating set is the same as that of the shaft 13 to be turned, ensuring that the end of the electric telescopic rod 21 is firmly fixed to the shaft 13 to be turned. The docking collar is provided so that when multiple restraint collars 16 approach each other, they can fit together.
