Description
Technical Field
[0001] The invention belongs to the field of turning, in particular to a turning device for electric bicycle accessories. Background Art
[0002] Turning is a processing method that removes material through the rotational motion of the workpiece and the linear or curved motion of the tool to obtain the desired shape and size. Turning is widely used in mechanical manufacturing and is suitable for processing various rotating parts, such as shafts, discs, sleeves, etc.
[0003] Accessories such as the center shaft of electric vehicles generally need to be processed by turning equipment; the rough material is usually fixed on the turning lathe, and then a series of operations such as end face processing, fine turning, and hole opening are performed on the rough material.
[0004] In the process of processing the axle of an electric vehicle, a traditional turning device generally fixes the shaft to be turned, then drives the shaft to be turned to rotate, and then uses different turning tools to process the shaft to be turned. Because a variety of different turning tools are needed in the process of axle processing, and drilling and other tasks are also required, there are many types of tools used, which leads to the need to frequently replace different processing tools, resulting in reduced processing efficiency. In addition, when processing an axle that is too long, in order to ensure processing stability, it is necessary to process one end of the axle first and then the other end. It is also impossible to directly use a long shaft to be turned to directly process multiple short axles, and the functionality and practicality are low.
[0005] To this end, 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, at least one technical problem raised in the background technology is solved.
[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: an electric bicycle accessory turning device according to the present invention comprises a processing box, a connecting box and a moving box, the connecting box is installed between the processing box and the moving box, an electric chuck for fixing the shaft to be turned is provided inside the processing box, a three-jaw chuck capable of movement is provided behind the electric chuck, a driving motor 2 is provided at the rear end of the three-jaw chuck for driving the three-jaw chuck to rotate, a recovery platform capable of translation and rotation is provided inside the processing box, a locking valve for fixing the shaft to be turned is provided in the middle of the recovery platform, a group of turning tools capable of lifting and lowering and a group of lathe drill bits 1 are provided inside the processing box, and a group of lathe drill bits 2 is provided at the front end of the recovery platform;
[0008] Fix the end of the shaft to be turned with the three-jaw chuck, move the three-jaw chuck to move the end of the shaft to be turned to the end of the electric chuck, and drive the three-jaw chuck to rotate through the driving motor 2. Then, as the three-jaw chuck continues to move toward the processing box, when a turning tool is needed for turning, each turning tool in a set of turning tools is different and is used to process different shapes according to needs. The whole set of turning tools is moved, and the required turning tool type is moved above the shaft to be turned, and then the turning tool is lowered and used to process the shaft to be turned. As the processing progresses, the three-jaw chuck The claw chuck moves forward continuously, pushing the unprocessed shaft to be turned toward 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 drive motor 2 can be stopped to let the shaft to be turned remain stationary first, and then the lathe drill bit 2 can be moved above the shaft to be turned, and the direction of the shaft to be turned can be adjusted by the drive motor 2, and different lathe drill bits can be used to drill the surface of the shaft to be turned, etc. When the shaft to be turned moves to a longer distance in the processing box, After separation, the recovery table can be moved and moved to align with the shaft to be turned, so that 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, and the locking valve and the recovery table can rotate relative to each other. Therefore, the shaft to be turned can continue to perform the rotation processing process. At the same time, the recovery table can also cooperate with the movement of the shaft to be turned to ensure the stable movement and rotation of the shaft to be turned. By using the locking valve to grasp the end of the shaft to be turned, not only can the outward-extending shaft to be turned be rotated stably, but also the unstable processing caused by excessive extension of the end can be reduced. At the same time, during the fixing stage of the locking valve, the shaft to be turned can be directly cut off with a turning tool, and the processed part remains in the locking valve, which not only does not affect subsequent processing, but also does not need to stop the driving motor 2, thus realizing the continuous processing of long shafts into multiple short shafts; at the same time, the multiple lathe drill bits 2 at the end of the recovery table can be started separately to drill holes in the shaft to be turned, thereby achieving synchronous drilling, or by adjusting the angle of the recovery table, non-vertical holes can be processed on the surface of the shaft to be turned.
[0009] Preferably, one side of the processing box is open, and an openable observation cover is installed at the opening, and the front end of the processing box is flippable and openable. Two sets of vertically distributed movable rails are fixed to the inner bottom of the processing box, and the movable end of the upper movable rail is connected to the recovery table. The middle part of the observation cover is made of transparent material, and the internal situation can be observed directly from the outside. The front end of the processing box is opened to install the shaft to be turned. The two sets of vertically distributed movable rails can drive the recovery table to move horizontally in any direction.
[0010] Preferably, a servo motor for driving the recovery platform to rotate is installed between the recovery platform and the movable end of the movable rail, and the outer side of the locking valve end is rotatably connected to an electric ring. Multiple lathe drill bits are arranged in a ring-like shape and equidistantly on the outer side of the electric ring. The recovery platform can be driven by the servo motor to rotate horizontally, so that the angle between the lathe drill bit and the shaft to be turned can be adjusted, so that holes in any direction can be processed on the surface of the shaft to be turned. The rotation of the electric ring can adjust different lathe drill bits to face the shaft to be turned, thereby processing different drill bits.
[0011] Preferably, an electric slide rail 1 for driving the movement of the drive motor 2 is installed at the bottom of the drive motor 2, and a plurality of rotatable rotating rings are provided between the three-jaw chuck and the electric chuck, and a plurality of electric telescopic rods are fixedly connected to the outer side of the rotating ring. When the shaft to be turned is long, in order to ensure the stability of the shaft to be turned during the initial rotation, the plurality of electric telescopic rods are extended to grasp the outer side of the shaft to be turned. During the rotation of the shaft to be turned, the rotating ring rotates synchronously, and when the three-jaw chuck moves forward, the rotating ring moves forward synchronously. When the rotating ring block contacts the electric chuck, the fixation of the electric telescopic rod is released until all the rotating rings are close to each other and all the electric telescopic rods are released.
[0012] Preferably, a restraining ring is rotatably clamped on the outer side of the rotating ring, and a driving motor three is fixedly connected to the inside of the restraining ring for driving the rotating ring to rotate. A plurality of vertically arranged fixing frames are fixedly connected to the outer side of the restraining ring. The three-jaw chuck and the driving motor two can both pass through the rotating ring. The driving motor three in the restraining ring can drive the rotating ring and the shaft to be turned to rotate synchronously. On the one hand, it reduces the load of the driving motor two. On the other hand, when releasing the fixation of the electric telescopic rod, the rotation of the rotating ring is maintained first, and then the electric telescopic rod is shortened to release the fixation. This method is safer and more stable.
[0013] Preferably, two groups of electric slide rails 2 are provided above the restraining collar, and the tops of the multiple fixing frames of the restraining collar are fixedly connected to the moving end of the electric slide rail 2. The electric slide rail 2 can drive the multiple restraining collars and the shaft to be turned to translate synchronously through the fixing frame. There are multiple moving ends of the electric slide rail 2, and they can all be driven individually. When the first restraining collar moves to the end, the electric slide rail 2 controls the restraining collar to stop moving, and waits until the subsequent restraining collars are close to the previous restraining collar, and then stops the subsequent restraining collars one by one, thereby realizing a stable fixing process of the longer shaft to be turned during the movement process.
[0014] Preferably, an electric slide rail 2 is installed at the bottom of the driving motor 2 for driving the driving motor 2 to move. The electric slide rail 2 is located below the restraining ring, and the driving motor 2 is driven to slide by the electric slide rail 2. Since the electric slide rail 2 is located below the restraining ring, the two will not touch each other. When the processing is completed, the driving motor 2 returns to its position first, and then the multiple restraining rings return to their position driven by the electric slide rail 2.
[0015] Preferably, a plurality of the turning tools are arranged in parallel to form a group, a plurality of the lathe drill bits are arranged in parallel to form a group, a group of turning tools and a group of lathe drill bits are arranged in parallel, and a movable platform capable of lifting and translating is fixed above the group of turning tools and the group of lathe drill bits, and an electric slide rail three is installed between the movable platform and the processing box to control the horizontal movement of the group of turning tools and the group of lathe drill bits, and move the required tools to the top of the shaft to be turned, and an electric push rod is provided in the movable platform to drive each turning tool and lathe drill bit to be lifted and lowered individually, so that the tool can be moved to the surface of the shaft to be turned for processing.
[0016] Preferably, the outer side of the electric chuck is rotatably clamped with a locking disk, and the inner side of the locking disk is installed with a driving motor 1 for driving the electric chuck to rotate. The end of the electric chuck serves as a reference surface for processing. After the three-jaw chuck moves close to the electric chuck, the electric chuck is first driven to rotate by the driving motor 1, and accelerated to the same speed as the shaft to be turned. After that, the electric chuck grasps the shaft to be turned. After the three-jaw chuck grasps the shaft to be turned, the shaft to be turned can be stably processed, and the electric chuck is released after the processing is completed; the electric chuck can also fix the shaft to be turned alone, and drive the shaft to be turned to rotate through the driving motor 1.
[0017] Preferably, an adapter set is installed at the end of the electric telescopic rod, and a docking sleeve is installed on the outside of the drive motor three. The curvature of the adapter set is the same as the curvature 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 setting of the docking sleeve is used to allow multiple restraining rings to fit together when they are close to each other.
[0018] The beneficial effects of the present invention are as follows:
[0019] 1. The turning device for electric bicycle accessories described in the present invention is provided with a set of turning tools that can be raised and lowered and a set of lathe drill bits. When turning tools are needed, each turning tool in a set of turning tools is different and is used to process different shapes according to needs. The whole set of turning tools is moved, and the required turning tool type is moved above the shaft to be turned. Then, the turning tool is lowered and the shaft to be turned is processed with the turning tool.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0030] like Figures 1 to 6 As shown, an electric bicycle accessory turning device according to an embodiment of the present invention comprises a processing box 1, a connecting box 2 and a moving box 3, wherein the connecting box 2 is installed between the processing box 1 and the moving box 3, an electric chuck 8 for fixing a shaft to be turned 13 is provided inside the processing box 1, a three-jaw chuck 19 capable of movement is provided at the rear of the electric chuck 8, a driving motor 20 for driving the three-jaw chuck 19 to rotate is provided at the rear end of the three-jaw chuck 19, a recovery table 5 capable of translation and rotation 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 recovery table 5, a group of turning tools 7 capable of lifting and lowering and a group of lathe drill bits 1 6 are provided inside the processing box 1, and a group of lathe drill bits 2 10 are provided at the front end of the recovery table 5;
[0031] Fix the end of the shaft to be turned 13 with the three-jaw chuck 19, move the three-jaw chuck 19 to move the end of the shaft to be turned 13 to the end of the electric chuck 8, and drive the three-jaw chuck 19 to rotate by the driving motor 20. Then, as the three-jaw chuck 19 continues to move toward the direction of the processing box 1, when it is necessary to use the turning tool 7 for turning, each turning tool 7 in a group of turning tools 7 is different and is used to process different shapes according to needs. The whole group of moving turning tools 7 moves the required type of turning tool 7 to the top of the shaft to be turned 13, and then the turning tool 7 is lowered and the turning tool 7 is used to process the shaft to be turned 13. As the processing proceeds, The three-jaw chuck 19 continuously moves forward, pushing the unprocessed shaft 13 to be turned toward the processing box 1. During the movement of the shaft 13 to be turned, the required type of turning tool 7 can be moved to the top of 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 driving motor 20 can be stopped to stop the shaft 13 to be turned and keep it still. Then, the lathe drill bit 10 can be moved to the top of the shaft 13 to be turned, and the direction of the shaft 13 to be turned can be adjusted by the driving motor 20. Different lathe drill bits 16 can be used to drill holes on the surface of the shaft 13 to be turned. When the shaft 13 to be turned moves to the processing box, 1, the recovery table 5 can be moved and moved to align with the shaft to be turned 13, so that the end of the shaft to be turned 13 is inserted into the locking valve 11. The locking valve 11 fixes the end of the shaft to be turned 13. The locking valve 11 and the recovery table 5 can rotate relative to each other, so the shaft to be turned 13 can continue to perform the rotation processing process. At the same time, the recovery table 5 can also cooperate with the movement of the shaft to be turned 13 to ensure the movement and rotation stability of the shaft to be turned 13. After using the locking valve 11 to grasp the end of the shaft to be turned 13, not only can the outwardly extended shaft to be turned 13 be rotated stably, but also the end extension of the shaft to be turned 13 can be reduced. The machining instability phenomenon caused by excessive cutting is eliminated, so that longer axles can be machined. At the same time, during the fixing stage of the locking valve 11, the turning tool 7 can be used to directly cut off the shaft 13 to be turned, and the machined part remains in the locking valve 11, which not only does not affect the subsequent machining, but also the driving motor 20 does not need to stop working, thereby realizing the continuous machining of the long shaft into multiple short shafts. At the same time, the multiple lathe drill bits 2 10 at the end of the recovery table 5 can be started separately to drill the shaft 13 to be turned, so that synchronous drilling can be performed, or by adjusting the angle of the recovery table 5, non-vertical holes can be machined on the surface of the shaft 13 to be turned.
[0032] One side of the processing box 1 is open, and an observation cover that can be opened is installed at the opening. The front end of the processing box 1 is flip-openable. Two sets of vertically distributed movable rails 4 are fixed to the bottom of the interior of the processing box 1. The movable end of the upper movable rail 4 is connected to the recovery platform 5.
[0033] During operation, the middle part of the observation cover is made of transparent material, so the internal situation can be observed directly from the outside. The front end of the processing box 1 is opened to install the shaft 13 to be turned. The two sets of vertically distributed moving rails 4 can drive the recovery platform 5 to move horizontally in any direction.
[0034] A servo motor 12 is installed between the recovery platform 5 and the movable end of the movable rail 4 to drive the recovery platform 5 to rotate. The outer side of the end of the locking valve 11 is rotatably connected to an electric ring. A plurality of lathe drill bits 10 are arranged in a circular shape and equidistantly on the outer side of the electric ring.
[0035] During operation, the servo motor 12 can drive the recovery table 5 to rotate horizontally, so that the angle between the lathe drill bit 2 10 and the shaft to be turned 13 can be adjusted, so that a drill hole in any direction can be processed on the surface of the shaft to be turned 13. The electric ring rotation can adjust different lathe drill bits 2 10 to face the shaft to be turned 13, thereby processing different drill bits.
[0036] An electric slide rail 15 is installed at the bottom of the drive motor 20 for driving the drive motor 20 to move. A plurality of rotatable rotating rings 24 are provided between the three-jaw chuck 19 and the electric chuck 8. A plurality of electric telescopic rods 21 are fixed to the outer side of the rotating ring 24.
[0037] During operation, when the shaft 13 to be turned is long, in order to ensure the stability of the shaft 13 to be turned during the initial rotation, multiple electric telescopic rods 21 are extended to grasp the outer side of the shaft 13 to be turned. During the rotation of the shaft 13 to be turned, 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 contacts 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.
[0038] The outer side of the rotating ring 24 is rotatably clamped with a restraining collar 16. The inner side of the restraining collar 16 is fixedly connected to a third driving motor 22 for driving the rotating ring 24 to rotate. The outer side of the restraining collar 16 is fixedly connected to a plurality of vertically arranged fixing brackets 17. The three-jaw chuck 19 and the second driving motor 20 can both pass through the rotating ring 24.
[0039] During operation, the driving motor three 22 in the restraining collar 16 can drive the rotating ring 24 to rotate synchronously with the shaft to be turned 13, which reduces the load of the driving motor two 20 on the one hand, and on the other hand, when releasing the fixation of the electric telescopic rod 21, the rotating ring 24 is kept rotating first, and then the electric telescopic rod 21 is shortened to release the fixation. This method is safer and more stable.
[0040] Two sets of electric slide rails 18 are provided above the restraining collar 16, and the tops of the multiple fixing frames 17 of the restraining collar 16 are fixedly connected to the moving ends of the electric slide rails 18;
[0041] During operation, the electric slide rail 2 18 can drive multiple restraining rings 16 and the shaft to be turned 13 to translate synchronously through the fixed frame 17. The electric slide rail 2 18 has multiple moving ends, and they can all be driven individually. When the first restraining ring 16 moves to the end, the electric slide rail 2 18 controls the restraining ring 16 to stop moving. After the subsequent restraining ring 16 is close to the previous restraining ring 16, the subsequent restraining rings 16 are stopped one by one. In this way, a stable fixing process of the longer shaft to be turned 13 during the movement is achieved.
[0042] The bottom of the second driving motor 20 is installed with a second electric slide rail 18 for driving the second driving motor 20 to move. The second electric slide rail 18 is located below the restraining ring 16.
[0043] During operation, the electric slide rail 2 18 drives the drive motor 20 to slide. Since the electric slide rail 2 18 is located below the restraining ring 16, the two will not touch each other. When the processing is completed, the drive motor 20 returns to its position first, and then the multiple restraining rings 16 return to their position under the drive of the electric slide rail 2 18.
[0044] A plurality of the turning tools 7 are arranged in parallel to form a group, and a plurality of the lathe drill bits 6 are arranged in parallel to form a group. A group of turning tools 7 and a group of lathe drill bits 6 are arranged in parallel, and a movable platform 9 capable of lifting and translating is fixed above the group of turning tools 7 and the group of lathe drill bits 6.
[0045] During operation, an electric slide rail three is installed between the movable platform 9 and the processing box 1, thereby controlling a group of turning tools 7 and a group of lathe drill bits 6 to move horizontally, and moving the required tools to the top of the shaft to be turned 13. An electric push rod is provided in the movable platform 9 to drive each turning tool 7 and lathe drill bit 6 to be raised and lowered individually, so that the tools can be moved to the surface of the shaft to be turned 13 for processing.
[0046] The outer side of the electric chuck 8 is rotatably connected to a locking plate 23, and the inner side of the locking plate 23 is installed with a driving motor 14 for driving the electric chuck 8 to rotate;
[0047] During operation, the end of the electric chuck 8 is used as the reference surface for processing. After the three-jaw chuck 19 moves close to the electric chuck 8, the electric chuck 8 is first driven to rotate by the drive motor 14 and accelerated 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 three-jaw chuck 19 grabs the shaft to be turned 13, the shaft to be turned 13 can be stably processed. After the processing is completed, 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 for rotation processing through the drive motor 14.
[0048] The end of the electric telescopic rod 21 is installed with an adapter set, and the outer side of the driving motor 3 22 is installed with a docking sleeve;
[0049] During operation, the curvature of the adapter set is the same as that of the shaft to be turned 13, ensuring that the end of the electric telescopic rod 21 is firmly fixed to the shaft to be turned 13. The setting of the docking sleeve allows multiple binding rings 16 to fit together when they are close to each other.
