Description

Technical Field

[0001] This invention relates to the field of power tool parts processing technology, and more specifically, to a processing mechanism and method for power tool parts. Background Technology

[0002] The processing of power tool parts uses metal bars as blanks and employs automated equipment such as CNC lathes and milling centers to complete multiple forming processes such as turning and milling, producing power tool parts such as output shafts, copper bushings, and gearbox components.

[0003] Currently, there are three main types of blanking processes for power tool parts bar stock processing in the industry. The first type is the direct bar stock processing and output mode, where the blank is shaped by the machine tool and then pushed forward to complete the blanking. The second type is the bar stock processing mode with a cutting process, where the blank is held by a three-jaw chuck, the finished product shape is first processed by milling, and then the shaped section is cut off from the clamping section by a cutting action. A single cycle of processing requires completing three steps in sequence: finished product blanking, chuck residual material blanking, and new blank loading. The third type is the robotic arm gripping and blanking mode, which is mainly suitable for whole-section material processing scenarios without a cutting process. After processing, the robotic arm directly grips the whole section of blank to complete the blanking.

[0004] When the existing material feeding method adopts the direct pushing scheme, the finished product after cutting is unrestrained and prone to splashing and unstable landing point, causing damage to the surface of the workpiece. If the finished product and the residual material in the chuck are pushed out at the same time, the finished product, residual material and processing debris will be mixed. The robotic arm grasping scheme cannot fully cover the entire process with the cutting process. The finished product is prone to splashing at the moment of cutting, which causes the robotic arm to respond late and has insufficient grasping stability. At the same time, the robotic arm can only grasp the finished product and cannot process the short residual material in the chuck at the same time. If a residual material unloading window is reserved, the robotic arm motion path needs to be increased, which further lengthens the production cycle. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a processing mechanism and processing method for power tool accessories.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a processing mechanism for power tool accessories, including a machine base.

[0007] The machining chuck is located on the top of the machine tool and is used to clamp and position the part blanks.

[0008] An electric guide rail is installed on the top of the machine tool, and a sliding table slides on the top of the electric guide rail.

[0009] An adjustment assembly is installed on the top of the slide table and on the side away from the machining chuck, with a guide rail installed on the side. Two sets of tool assemblies are installed on the top of the adjustment assembly. The adjustment assembly is used to drive the two sets of tool assemblies to move, and the two sets of tool assemblies cooperate to process the blank.

[0010] A material feeding assembly is installed on top of an adjustment assembly. The material feeding assembly includes a servo motor installed on top of the adjustment assembly and a disc rotating on top of the adjustment assembly. The output end of the servo motor is connected to the center of the disc. A material feeding channel for collecting waste material is opened on the side wall of the servo motor. The top and bottom of the disc are equipped with material handling mechanisms for clamping finished product feeding and blank feeding.

[0011] Both sets of material handling mechanisms include a bracket connected to the disc body. A rotating seat is mounted on the bracket. A material handling clamp is installed on the side of the rotating seat away from the disc body. Before the finished product is cut, one of the material handling clamps is used to pre-clamp and rotate accordingly. After the finished product is cut, the disc body rotates to discharge waste material through the material discharge channel. After the waste material is discharged, the disc body rotates to feed the billet using the other material handling clamp.

[0012] The present invention is further configured such that: telescopic cylinders are installed at the top and bottom of the disc body, and the piston rod of the telescopic cylinder is connected to the grinding disc.

[0013] The present invention is further configured such that the end of the rotating seat opposite to the grinding disc is provided with a wear-resistant coating.

[0014] The invention is further configured such that: the adjustment assembly includes a housing mounted on the top of the slide table, and two carriers slide inside the housing, the two carriers extending to the top of the housing and respectively connected to two sets of tool assemblies.

[0015] The present invention is further configured such that: a groove is provided on the top of the shell, and the disc is embedded in the groove.

[0016] The present invention is further configured such that: a drive motor is installed on one side of the housing, the output end of the drive motor extends into the interior of the housing and is connected to a lead screw, and the lead screw is threadedly connected to two carrier seats.

[0017] The present invention is further configured such that: a guide rail is installed inside the housing, a slider slides on the top of the guide rail, two carriers are correspondingly arranged with the two sliders, and the carriers are installed on the top of the sliders.

[0018] The present invention is further configured such that: both sets of the tool assemblies include slides, the two slides are correspondingly arranged with the two carriers, the slides are mounted on the top of the corresponding carriers, and a milling cutter is mounted on one side of the slide.

[0019] The present invention is further configured such that: a drive mechanism is installed on the top of the machine tool, the output end of the drive mechanism is connected to the processing chuck, and a cover is installed on the top of the machine tool.

[0020] A method for processing power tool accessories, using a power tool accessory processing mechanism as described above, includes the following steps: S1. The blank to be processed is clamped and rotated using the processing chuck. Then, the slide table is controlled to slide along the extension direction of the electric guide rail, causing the adjustment component, the tool component, and the blanking component to move closer to the blank. After that, the adjustment component controls the two sets of tool components to cooperate in processing the outer wall of the blank.

[0021] S2. After the billet is processed into a finished product, the processing chuck and the billet are first controlled to stop rotating. The servo motor drives the chuck to rotate, causing one set of material-picking chucks to face the finished product direction. Then, the slide moves closer to the processing chuck, causing one set of tool assemblies to be in the position where the finished product and scrap are to be cut. At this time, the material-picking chuck facing the finished product direction clamps the stationary finished product part, while the other material-picking chuck uses an external robot to load the billet. Subsequently, the processing chuck drives the finished product to rotate, and the corresponding material-picking chuck rotates synchronously. One set of tool assemblies cuts and separates the finished product from the scrap.

[0022] S3. After the finished product and waste are separated, the slide moves away from the processing chuck. At the same time, the servo motor drives the chuck to rotate counterclockwise, causing the unloading channel to face the processing chuck. The unloading material is pushed out by the pusher cylinder inside the processing chuck and falls into the unloading channel for guidance. The unloading material that falls through the unloading channel is discharged by the guide rail.

[0023] S4. Then the servo motor drives the disc to rotate counterclockwise again, causing the material chuck holding the new blank to rotate to the position of the processing chuck. Then the slide moves closer to the processing chuck, causing the blank to be sent into the interior of the processing chuck. The processing chuck clamps the new blank, while the material chuck holding the finished product drops the blank during the rotation. After being idle, the external robot arm clamps the new blank for later use.

[0024] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up a disc body, the disc body can be rotated in sections to set up finished product clamping and unloading, waste material guiding and discharge, and new billet loading on the disc body. The disc body moves forward and backward axially synchronously with the slide table. Before the workpiece is cut, the material picker pre-clamps the finished product to avoid the finished product losing its constraint and splashing or being damaged by collision at the moment of cutting. After the finished product is cut, the unloading channel and another set of material picker are switched in sequence by the indexing rotation of the disc body to unload waste and load billet, so as to realize the classified collection of finished products and waste materials and avoid mixing. At the same time, the alternating operation of the two sets of material picker mechanisms can compress the loading and unloading cycle time, without the need to add multiple sets of independent robotic arms, thus improving the overall processing efficiency of the machine.

[0025] (2) By setting the two pick-up chucks to be able to rotate, the finished product is pre-clamped by the pick-up chucks that can rotate before the workpiece is cut. Then, during the cutting process, the pick-up chucks rotate synchronously with the finished product to avoid interference when the finished product is clamped. In addition, the follow-up rotation function further alleviates the problem of finished product splashing.

[0026] (3) When the material pick-up chuck moves the finished product out of the processing chuck, the piston rod of the telescopic cylinder extends and pushes the grinding disc to move towards the rotating seat. After the end face of the grinding disc contacts the end face of the rotating seat, sliding friction is generated, which consumes the rotational kinetic energy of the rotating seat, so that the rotating seat and the material pick-up chuck decelerate rapidly until they stop, ensuring that the finished product is stationary when unloading, avoiding the finished product from moving or being thrown out due to centrifugal force when unloading, and improving the accuracy and safety of the unloading point.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0039] Please see Figures 1-8 The present invention provides the following technical solutions: Example 1, see Figure 1 and Figure 2 A processing mechanism for power tool accessories includes a machine base 1. A drive mechanism 4 is mounted on the top of the machine base 1. The output end of the drive mechanism 4 is connected to a processing chuck 3, which is used to clamp and position the accessory blank. The drive mechanism 4 consists of a housing, a rotary motor, a synchronous belt drive mechanism, and a rotating tube. The processing chuck 3 is connected to the rotating tube. One pulley of the synchronous belt drive mechanism is sleeved on the outer wall of the rotating tube, and the other pulley is connected to the output end of the rotary motor. The synchronous belt drives the outer walls of the two pulleys. The rotary motor drives the corresponding pulleys to rotate, which causes the drive belt to drive the other pulley, the rotating tube, and the processing chuck 3 to rotate. When the processing chuck 3 rotates, it drives the accessory blank to rotate, which facilitates subsequent processing. A cover 2 is mounted on the top of the machine base 1 to protect the blank during processing.

[0040] See Figure 1 and Figure 2An electric guide rail 5 is installed on the top of the machine base 1. A slide table 51 slides on the top of the electric guide rail 5. An adjustment component 6 is installed on the top of the slide table 51. The electric guide rail 5 is used to drive the slide table 51 to slide, thereby adjusting the position of the adjustment component 6. Two sets of tool assemblies 7 are installed on the top of the adjustment component 6. The adjustment component 6 is used to drive the two sets of tool assemblies 7 to move. The two sets of tool assemblies 7 cooperate to process the blank.

[0041] Specifically, the electric guide rail 5 is arranged along the axial direction of the blank. By driving the slide table 51 to slide back and forth, it drives the adjustment component 6 and the tool assembly 7 to move closer to or further away from the machining chuck 3, thereby realizing the axial feed and retraction of the tool. The adjustment component 6 can drive the two sets of tool assemblies 7 to move relative to each other in the radial direction of the blank, adjust the radial distance between the tool and the outer wall of the blank, and control the radial depth of cut. The two sets of tools work together to complete the multi-process cutting of the outer wall of the blank.

[0042] See Figures 2-4 The adjustment component 6 includes a housing 61 mounted on the top of the slide table 51 and a groove 62 formed on the top of the housing 61. Two carriers 67 slide inside the housing 61. A guide rail 65 is installed inside the housing 61. A slider 66 slides on the top of the guide rail 65. The two carriers 67 are correspondingly arranged with the two sliders 66. The carriers 67 are mounted on the top of the sliders 66. The two carriers 67 extend to the top of the housing 61 and are respectively connected to two sets of tool assemblies 7. The carriers 67 are the mounting carriers of the tool assemblies 7. When the carriers 67 slide inside the housing 61, they can drive the tool assemblies 7 to move synchronously, that is, slide radially, thereby realizing the adjustment of the radial position of the tool.

[0043] See Figures 2-4 A drive motor 63 is installed on one side of the housing 61. The output end of the drive motor 63 extends into the interior of the housing 61 and is connected to a lead screw 64. The lead screw 64 is threadedly connected to two carriers 67. The drive motor 63 drives the lead screw 64 to rotate synchronously, so that the two carriers 67 move synchronously, thereby realizing the synchronous movement of the two sets of tool assemblies 7. That is, when one set of tool assemblies 7 moves closer to the blank held by the machining chuck 3, the other set of tool assemblies 7 moves away synchronously, thus alternating the use of the two sets of tool assemblies 7.

[0044] See Figures 2-4 Both sets of tool assemblies 7 include slides 71. The two slides 71 are correspondingly arranged with the two carriers 67. The slides 71 are installed on the top of the corresponding carriers 67. A milling cutter 72 is installed on one side of the slides 71. The slides 71 move synchronously with the carriers 67. During machining, the milling cutter 72 moves with the slides 71 to a set radial position and contacts the outer wall of the rotating blank to complete the machining of the outer wall and cut off the blank.

[0045] A pusher cylinder is also installed inside the housing of the drive mechanism 4, and the piston rod of the pusher cylinder extends to the center point of the processing chuck 3. When the finished product is processed, the piston rod of the pusher cylinder is quickly pushed out, and the processing chuck 3 is released from clamping, and the waste material is directly pushed out and dropped.

[0046] Since the finished product needs to be separated from the clamped waste material after processing, without intervention, the cut finished product is prone to splashing and unstable landing point due to the lack of constraint, causing damage to the workpiece surface. If the finished product and the residual material in the chuck are pushed out simultaneously, the finished product, residual material and processing debris will mix. The robotic arm needs to use a loading robotic arm and a unloading robotic arm separately, with a total of two sets of mechanisms working separately. A single robotic arm cannot completely cover the entire process including the cutting process. The finished product is prone to splashing at the moment of cutting, which causes the robotic arm to respond late and has insufficient gripping stability. At the same time, the robotic arm can only grasp the finished product and cannot handle the short residual material in the processing chuck 3 at the same time. If a residual material unloading window is reserved, an additional robotic arm motion path is required, which further lengthens the production cycle.

[0047] For this purpose, please refer to Figure 2 and Figure 3 A blanking assembly 8 is installed on the top of the housing 61. The blanking assembly 8 can move axially synchronously with the adjusting assembly 6 and move forward and backward synchronously with the cutting tool assembly 7. The blanking assembly 8 integrates the functions of finished product clamping and blanking, waste material guiding and discharge, and new billet loading. It can complete the cutting, waste discharge, and loading processes sequentially at the same station without the need for additional sets of robotic arms and stations. It realizes the classification and blanking of finished products and waste materials, shortens the loading and unloading cycle time. The specific structure of the blanking assembly 8 is as follows: See Figure 3 and Figure 5 The material feeding assembly 8 includes a servo motor 81 mounted on the top of the adjustment assembly 6 and a disk 82 rotating on the top of the adjustment assembly 6. The output end of the servo motor 81 is connected to the center of the disk 82. The side wall of the servo motor 81 is provided with a material feeding channel 84 for collecting waste materials. The top and bottom of the disk 82 are both equipped with a material handling mechanism 83 for clamping finished product feeding and blank feeding.

[0048] Servo motor 81 provides rotational power to disk 82, controlling the rotation angle and start / stop position of disk 82. Disk 82 serves as the mounting carrier for material handling mechanism 83, and can switch between different work positions during rotation without interfering with the guide rail 65 inside housing 61. Both sets of material handling mechanisms 83 have finished product clamping and unloading functions as well as new billet loading functions, and the two functions of the two sets of material handling mechanisms 83 are used alternately.

[0049] When the blank is processed into a finished product but not yet cut off, the processing chuck 3 and the blank stop rotating and remain stationary. The two sets of tool assemblies 7 adjust their positions so that the finished product is between the two sets of tool assemblies 7. Then, a set of material handling mechanisms 83 rotates to face the processing chuck 3. At this time, through the movement of the slide table 51, the entire unloading assembly 8 and the two sets of tool assemblies 7 move with the slide table 51. The tool assembly 7 moves to the position where the finished product is to be cut, and the finished product is inserted into this set of material handling mechanisms 83. This set of material handling mechanisms 83 clamps the stationary finished product. Then, the processing chuck 3 is driven to start rotating by the drive mechanism 4, that is, the blank and the corresponding material handling mechanism 83 start to rotate. The two sets of tool assemblies 7 start to move, that is, one set of tool assemblies 7 starts to cut the cutting position between the finished product and the scrap of the blank until the finished product and the scrap of the blank are separated. During the above process, the other set of material handling mechanisms 83 uses an external robot arm to clamp new blanks for standby operation.

[0050] After the finished product is obtained, the two sets of tool assemblies 7 are reset. The slide table 51 drives the unloading assembly 8 and the two sets of tool assemblies 7 to retract away from the processing chuck 3. The disc body 82 rotates 90 degrees counterclockwise towards the housing 61, so that the unloading channel 84 faces the processing chuck 3 and is aligned with the discharge end of the processing chuck 3. The pusher cylinder pushes out the waste material remaining in the processing chuck 3, and the waste material is guided to flow into the guide rail 9 for unloading.

[0051] See Figure 9 At the bottom of the machine 1, there is a material discharge chute. At the bottom of the material discharge chute, there are two collection frames. These two collection frames can be moved by electric drive, that is, the two collection frames are controlled to alternately face the material discharge chute. This electric drive method can be electric slide rail drive, which is not specifically limited here. The two collection frames are waste collection frame and finished product collection frame respectively.

[0052] See Figure 9 The waste material falls into the discharge chute via the guide rail 9, and then into the waste collection box. At this time, the waste collection box is driven away from the discharge chute by electricity, and the finished product collection box moves below the discharge chute.

[0053] Then, the disc 82 rotates 90 degrees counterclockwise again, causing the material-grabbing mechanism 83 holding the new billet to align with the processing chuck 3. The billet is then fed into the processing chuck 3 via the movement of the slide table 51, where it is processed again using the two sets of tool assemblies 7. Simultaneously, the material-grabbing mechanism 83 holding the finished product rotates from inside the housing 61 to a direction away from the processing chuck 3. During this rotation, the material-grabbing mechanism 83 releases the finished product, which, under the influence of gravity, passes sequentially through the guide rail 9, the drop chute, and the finished product collection frame. When the material-grabbing mechanism 83 rotates to a direction away from the processing chuck 3, it is in an idle state. Subsequently, an external robotic arm holds a new billet for later use, and this process is repeated.

[0054] By using alternating waste collection boxes and finished product collection boxes, waste can be collected separately, avoiding mixing with finished products.

[0055] However, since the finished product needs to rotate rapidly during cutting, further improvements are needed to the material handling mechanism 83 to enhance its adaptability. The specific structure of the material handling mechanism 83 is as follows: See Figures 5-8 Both sets of material handling mechanisms 83 include a bracket 831 connected to the disc body 82. A rotating seat 834 rotates on the bracket 831. A material handling clamp 833 is installed on the side of the rotating seat 834 away from the disc body 82. When the finished product is processed but not cut, the rotation is stopped by the processing clamp 3 and the drive mechanism 4. The material handling clamp 833 in one set of material handling mechanisms 83 is used for pre-clamping. When the finished product is cut, the drive mechanism 4 drives the processing clamp 3 to start rotating, and the material handling clamp 833 follows the processing clamp 3 and the finished product to rotate. After the finished product is cut, the disc body 82 rotates 90 degrees counterclockwise and the waste material is discharged using the discharge channel 84 and the guide rail 9. After the waste material is discharged, the disc body 82 rotates 90 degrees counterclockwise and the blank is loaded using the material handling clamp 833 in the other set of material handling mechanisms 83.

[0056] Specifically, the rotating seat 834 can rotate on the bracket 831, driving the material chuck 833 to rotate synchronously. Before processing and cutting, the material chuck 833 is axially fed with the slide table 51, while the finished product stops rotating. The material chuck 833 clamps the end of the finished product in a stationary state. Afterward, the finished product rotates, causing the material chuck 833 and the rotating seat 834 to move synchronously, ensuring that the finished product is still in a clamped and constrained state at the moment of cutting, avoiding splashing. After the finished product is cut, the disc body 82 rotates 90 degrees counterclockwise, and the material drop channel 84 is aligned with the processing chuck 3, driving... The pusher cylinder installed inside mechanism 4 extends from the processing chuck 3 to push out the residual waste material. The waste material is discharged along the discharge channel 84. After the disc body 82 rotates 90 degrees counterclockwise again, the picking chuck 833 loaded with new billet is aligned with the processing chuck 3. The billet is fed into the processing chuck 3 by the slide table 51 to complete the loading. This realizes the continuous cycle operation of finished product clamping, cutting, waste discharge and loading. While ensuring that finished products and waste materials do not mix, it enables finished products and waste materials to be dropped quickly. At the same time, it ensures that finished products will not splash due to rotation when they are dropped.

[0057] In the second embodiment, after the finished product is picked up by the material picking mechanism 83, the finished product continues to rotate on the material picking mechanism 83 because the finished product is in a high-speed rotating state. At the moment of feeding, the finished product may still fly out.

[0058] For this purpose, please refer to Figures 5-8Telescopic cylinders 832 are installed at the top and bottom of the disc body 82. A grinding disc 835 is connected to the piston rod of the telescopic cylinder 832. The end of the rotating seat 834 opposite to the grinding disc 835 is provided with a wear-resistant coating. The wear-resistant coating can be a metal-ceramic coating, which is not specifically limited here. When the material pick-up chuck 833 moves the finished product out of the processing chuck 3, the piston rod of the telescopic cylinder 832 extends and pushes the grinding disc 835 to move towards the rotating seat 834. After the end face of the grinding disc 835 contacts the end face of the rotating seat 834, sliding friction is generated, which consumes the rotational kinetic energy of the rotating seat 834, so that the rotating seat 834 and the material pick-up chuck 833 decelerate quickly until they stop, ensuring that the finished product is stationary when unloading and preventing it from flying out.

[0059] Example 3: A method for processing power tool accessories, using the power tool accessory processing mechanism described above, includes the following steps: S1. The blank to be processed is clamped and rotated using the processing chuck 3. Then, the slide table 51 is controlled to slide along the extension direction of the electric guide rail 5, causing the adjustment component 6, the tool component 7, and the blanking component 8 to move closer to the blank. After that, the adjustment component 6 controls the two sets of tool components 7 to cooperate in processing the outer wall of the blank.

[0060] The more specific steps in S1 are as follows: S11. The blank to be processed is clamped by the processing chuck 3, and the processing chuck 3 and the blank are rotated by the drive mechanism 4. Then, the slide table 51 is controlled to slide along the extension direction of the electric guide rail 5, so that the adjustment component 6, the tool component 7, and the blanking component 8 all move closer to the blank.

[0061] S12. Then, the drive motor 63 drives the lead screw 64 to rotate, causing the two carriers 67 to move synchronously. The two carriers 67 drive the corresponding tool assembly 7 to move, and the two milling cutters 72 are used to alternately process the outer wall of the rotating blank.

[0062] S2. After the billet is processed into a finished product, the processing chuck 3 and the billet are first controlled to stop rotating. The servo motor 81 drives the disc body 82 to rotate, causing one set of pick-up chucks 833 to face the finished product direction. Then the slide table 51 moves closer to the processing chuck 3, causing one set of tool assemblies 7 to be in the position to be cut off between the finished product and the scrap. At this time, the pick-up chuck 833 facing the finished product direction clamps the stationary finished product part, while the other pick-up chuck 833 uses an external robot arm to perform the billet loading operation. Then the processing chuck 3 drives the finished product to rotate. At this time, the corresponding pick-up chuck 833 rotates synchronously, and one set of tool assemblies 7 cuts off the finished product, causing the finished product and the scrap to separate.

[0063] S3. After the finished product and waste are separated, the slide table 51 retracts away from the processing chuck 3. At the same time, the servo motor 81 drives the disk body 82 to rotate 90 degrees counterclockwise, causing the unloading channel 84 to face the processing chuck 3. The unloading material is pushed out by the pusher cylinder inside the processing chuck 3 and falls into the unloading channel 84 for guidance. The unloading material that falls through the unloading channel 84 is discharged by the guide rail 9.

[0064] S4. Then, the servo motor 81 drives the disk body 82 to rotate 90 degrees counterclockwise again, causing the material pick-up chuck 833 holding the new blank to rotate to the position of the processing chuck 3. Then, the slide table 51 moves closer to the processing chuck 3, causing the blank to be sent into the interior of the processing chuck 3. The processing chuck 3 completes the clamping of the new blank. At the same time, the material pick-up chuck 833 holding the finished product completes the unloading during the rotation. After being idle, the external robot arm completes the clamping of the new blank for later use.

[0065] The more specific steps for S4 are as follows: S41. Then, the servo motor 81 drives the disk body 82 to rotate 90 degrees counterclockwise again, causing the material pick-up chuck 833 holding the blank to rotate to the position of the processing chuck 3. Then the slide table 51 moves closer to the processing chuck 3, causing the blank to be sent into the interior of the processing chuck 3, and the processing chuck 3 completes the clamping of the blank.

[0066] S42. Simultaneously, after the finished product is moved out of the processing chuck 3 by the material-grabbing chuck 833 holding the finished product, the piston rod of the corresponding telescopic cylinder 832 immediately extends, pushing the grinding disc 835 to move towards the rotating seat 834. The end face of the grinding disc 835 contacts the end face of the rotating seat 834, generating sliding friction, which consumes the rotational kinetic energy of the rotating seat 834, and finally makes the rotating seat 834 and the material-grabbing chuck 833 stop rotating quickly. When this set of material-grabbing chucks 833 rotates with the disc body 82 to the direction away from the processing chuck 3, the material-grabbing chuck 833 releases the finished product, and the finished product is dropped by gravity. After rotating to the target position, the external robot arm completes the clamping and preparation of the new blank.

[0067] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

10. A method for processing power tool accessories, using a processing mechanism for power tool accessories as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. The blank to be processed is clamped and rotated using the processing chuck (3). Then, the slide (51) is controlled to slide along the extension direction of the electric guide rail (5), causing the adjustment component (6), the tool component (7), and the blanking component (8) to move closer to the blank. Then, the adjustment component (6) controls the two sets of tool components (7) to cooperate in processing the outer wall of the blank. S2. After the billet is processed into a finished product, the processing chuck (3) and the billet are first controlled to stop rotating. The servo motor (81) drives the disc (82) to rotate, so that one of the pick-up chucks (833) faces the finished product direction. Then the slide (51) moves closer to the processing chuck (3), so that one of the tool assemblies (7) is in the position of finished product and scrap to be cut. At this time, the pick-up chuck (833) facing the finished product direction clamps the stationary finished product part, while the other pick-up chuck (833) uses an external robot to perform the billet loading operation. Then the processing chuck (3) drives the finished product to rotate. At this time, the corresponding pick-up chuck (833) rotates synchronously. One of the tool assemblies (7) cuts the finished product, so that the finished product and scrap are separated. S3. After the finished product and the waste are separated, the slide (51) moves away from the processing chuck (3). At the same time, the servo motor (81) drives the disc (82) to rotate 90 degrees counterclockwise, so that the material drop channel (84) faces the processing chuck (3). The material drop cylinder inside the processing chuck (3) pushes the waste out and falls into the guide drop channel (84). The waste dropped through the material drop channel (84) is discharged by the guide rail (9). S4. Then the servo motor (81) drives the disk (82) to rotate 90 degrees counterclockwise again, causing the material pick-up chuck (833) holding the new blank to rotate to the position of the processing chuck (3). Then the slide (51) moves closer to the processing chuck (3), causing the blank to be sent into the interior of the processing chuck (3). The processing chuck (3) clamps the new blank, and at the same time, the material pick-up chuck (833) holding the finished product completes the material drop during the rotation. After being idle, the new blank is clamped by the external robot arm for later use.
