[0061] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] In the prior art, the structure of conventional electric drills is relatively complicated. The mainstream method is basically to set the rotating device and the moving device of the electric drill on the same structure. In this way, no matter which device is damaged, the entire structure needs to be replaced, and the maintenance and replacement costs are high. In addition, such a design will also make the structure of the electric drill complicated. Therefore, it is necessary to design a novel multifunctional electric drill.

[0063] See also Figure 1 to Figure 2 As shown, a multifunctional electric drill includes a shell 100, a push clamp assembly 300, a rotating clamp assembly 400 and a control assembly 500, wherein the push clamp assembly 300 is arranged in the shell 100, the clamp 340 of the push clamp assembly 300 is used to clamp a tool 600, the rotating clamp assembly 400 is arranged in the shell 100, the rotating clamp assembly 400 is used to rotate the clamp 340, and the control assembly 500 is arranged in the shell 100 and is electrically connected to the push clamp assembly 300 and the rotating clamp assembly 400, wherein the push clamp assembly 300 is used to push the clamp 340 to connect with the rotating clamp assembly 400 and the tool 600, and the rotating clamp assembly 400 is used to drive the tool 600 on the clamp 340 to rotate.

[0064] Specifically, the multifunctional electric drill refers to an electric machine for driving screws or drilling holes, the push-clamp assembly 300 refers to a device for pushing the clamp 340 of the push-clamp assembly 300 to move, and the rotating clamp assembly 400 refers to a device for driving the clamp 340 on the push-clamp assembly 300 to rotate. The push-clamp assembly 300 and the rotating clamp assembly 400 are both installed in the housing 100, the push-clamp assembly 300 is located at the lower part of the housing 100, and the rotating clamp assembly 400 is located at the upper part of the housing 100 and at the left side of the push-clamp assembly 300. This arrangement can make full use of the space in the housing 100, so that the clamp 340 of the push-clamp assembly 300 can cooperate with the rotating clamp assembly 400, and the installation positions of the rotating clamp assembly 400 and the push-clamp assembly 300 are reasonably arranged. The push-clamp assembly 300 is used to push the clamp 340 to connect with the rotating clamp assembly 400 and the tool 600, and the rotating clamp assembly 400 is used to drive the tool 600 on the clamp 340 to rotate.

[0065] It can be understood that the clamp 340 of the push clamp assembly 300 moves to the working position or the initial position, the working position refers to the position where the clamp 340 pushes the tool 600 out of the push clamp assembly 300; the initial position refers to the position where the rotating clamp assembly 400 stops rotating the clamp 340, and the clamp 340 is disconnected from the rotating clamp assembly 400. The above conditions are set in this application to facilitate the installation positions of the push clamp assembly 300 and the rotating clamp assembly 400 to be set separately, reduce the complexity of the equipment, reduce the difficulty of operation and maintenance costs, simplify the structure, and provide convenience for users.

[0066] See also Figure 2 , Figure 6 and Figure 7 As shown, in another embodiment of the present application, the push-clamp assembly 300 includes: a screw table 310, a screw rod 320, a slider 330, a clamp 340 and a push-clamp servo 350, the screw table 310 is arranged in the housing 100; the screw rod 320 is rotatably arranged on the screw table 310; the slider 330 is rotatably arranged on the screw rod 320; the clamp 340 is rotatably arranged on the slider 330, and is used to clamp the tool 600; the push-clamp servo 350 is arranged on the screw table 310 and is connected to the screw rod 320, and the push-clamp servo 350 is electrically connected to the control assembly 500.

[0067] Specifically, the push-and-clamp assembly 300 includes a screw platform 310, a screw rod 320, a slider 330, a fixture 340, and a push-and-clamp servo 350. The screw platform 310 is installed on the lower side of the housing 100. A recessed portion is provided in the middle of the screw platform 310 for installing the screw rod 320. The push-and-clamp servo 350 is installed at the bottom of the screw platform 310. The output shaft of the push-and-clamp servo 350 is connected to the screw rod 320. The slider 330 is installed on the screw rod 320. The slider 330 is provided with a hole matching the thread of the screw rod 320. The rotatable fixture 340 is installed on the slider 330. When the push-and-clamp servo 350 is started to drive the screw rod 320 to rotate, the screw rod 320 drives the slider 330 to move, thereby driving the fixture 340 on the slider 330 to reach the working position or the initial position. In the present application, the cooperation of the screw rod 320 and the slider 330 to drive the movement of the clamp 340 is conducive to accurately controlling the moving distance of the clamp 340, and the structure of the screw rod 320 and the screw platform 310 is relatively simple, and also has self-locking performance and strong stability, which is conducive to reducing costs.

[0068] It is worth noting that the clamp 340 is rotatably connected to the slider 330. Figure 7 As shown, a base is provided on the slider 330 , and the clamp 340 can rotate in the base, so that when the rotating clamp assembly 400 is connected to the clamp 340 , the clamp 340 can also rotate.

[0069] For example Figure 2 , Figure 6 and Figure 7 As shown, the transfer clamp assembly 400 includes a transfer clamp servo 410 and a transmission component 420. The transfer clamp servo 410 is arranged in the housing 100 and is located on one side of the screw stage 310. The transfer clamp servo 410 is electrically connected to the control assembly 500; one end of the transmission component 420 is connected to the transfer clamp servo 410, wherein when the clamp 340 reaches the working position, the other end of the transmission component 420 is connected to the clamp 340; when the clamp 340 reaches the initial position, the other end of the transmission component 420 is disconnected from the clamp 340.

[0070] Specifically, a transfer clamp assembly 400 is provided in this embodiment, and the transfer clamp assembly 400 includes a transfer clamp servo 410 and a transmission component 420. The transfer clamp servo 410 is installed in the shell 100 and is located on the upper side of the screw table 310. This arrangement is conducive to making full use of the space in the shell 100; one end of the transmission component 420 is connected to the transfer clamp servo 410, and the other end is connected or disconnected to the clamp 340. The connection or disconnection is determined according to whether the clamp 340 is in the working position or the initial position. The transmission component 420 is located on the left side of the transfer clamp servo 410 and the screw table 310. The specific structure of the transmission component 420 can be adjusted by technicians in this field according to actual needs.

[0071] Exemplarily, the output shaft of the rotary clamp servo 410 is installed in the housing 100 in the same direction as the output direction of the fixture 340. At this time, there is no need to change the transmission direction. First, the first gear is installed on the output shaft of the rotary clamp servo 410, and the second gear is installed on the fixture 340. When the fixture 340 is in the working position, the first gear is meshed with the second gear. The control component 500 starts the rotary clamp servo 410 to drive the tool 600 on the fixture 340 to rotate. When the fixture 340 is in the initial position, the rotary clamp servo 410 stops, and the first gear is separated from the second gear.

[0072] For example Figure 2 , Figure 6 and Figure 7 As shown, in a specific embodiment of the present application, the transmission component 420 includes a transmission shaft 422, a first bevel gear 421, a second bevel gear 423, a third bevel gear 424 and a fourth bevel gear 425. The transmission shaft 422 is rotatably arranged in the housing 100 and is located on the left side of the screw stage 310; the first bevel gear 421 is arranged on the output shaft of the rotating clamp servo 410; the third bevel gear 424 is arranged at one end of the transmission shaft 422 and meshes with the second bevel gear 423. The second bevel gear 423 is arranged at one end of the transmission shaft 422 and is meshed with the second bevel gear 423, the third bevel gear 424 is arranged at the other end of the transmission shaft 422, and the fourth bevel gear 425 is arranged on the clamp 340; wherein, when the clamp 340 reaches the working position, the third bevel gear 424 is meshed with the fourth bevel gear 425; when the clamp 340 reaches the initial position, the third bevel gear 424 is separated from the fourth bevel gear 425.

[0073] Specifically, the present embodiment discloses a specific structure of the transmission component 420, which includes a transmission shaft 422, a first bevel gear 421, a second bevel gear 423, a third bevel gear 424, and a fourth bevel gear 425. The transmission shaft 422 is rotatably mounted in the housing 100 and is located on the left side of the lead screw stage 310, so that the fixture 340 of the lead screw stage 310 can cooperate with the transmission shaft 422, and the space in the housing 100 can be fully utilized. At the same time, the second bevel gear 423 and the third bevel gear 424 are respectively mounted at both ends of the transmission shaft 422, the output shaft of the rotating clamp servo 410 is mounted with the first bevel gear 421, and the fourth bevel gear 425 is mounted on the fixture 340. When the clamp 340 reaches the working position, the third bevel gear 424 meshes with the fourth bevel gear 425, and the control component 500 starts the rotating clamp servo 410 to drive the first bevel gear 421 to rotate, and then the first bevel gear 421 drives the second bevel gear 423 to rotate, and then drives the transmission shaft 422 to rotate, and the third bevel gear 424 of the transmission shaft 422 drives the fourth bevel gear 425 of the clamp 340 to rotate, and then drives the clamp 340 to rotate; when the clamp 340 reaches the initial position, the rotating clamp servo 410 stops rotating to facilitate the separation of the fourth bevel gear 425 of the clamp 340 and the third bevel gear 424 of the transmission shaft 422. In the present application, the transmission shaft 422, the first bevel gear 421, the second bevel gear 423, the third bevel gear 424 and the fourth bevel gear 425 are arranged. On the one hand, the transmission direction of the output shaft of the rotary clamp servo 410 can be changed so that the space in the housing 100 can be fully utilized. On the other hand, the coordinated arrangement of multiple bevel gears enables the rotary clamp servo 410 to achieve a deceleration effect, reduce the rotation speed of the rotary clamp servo 410, and avoid the excessive rotation speed affecting the stability of the tool 600 clamped on the fixture 340.

[0074] It should be noted that the transmission ratio of the first bevel gear 421 and the second bevel gear 423 is 2.5-4, and the transmission ratio of the third bevel gear 424 and the fourth bevel gear 425 is 2.5-4. Using a transmission ratio greater than 1 is conducive to reducing the rotation speed of the transfer servo 410 and achieving a deceleration effect.

[0075] See also Figures 1 to 5 As shown, in another embodiment of the present application, the multifunctional electric drill further includes a tool changing assembly 200, which is disposed on the housing 100 and electrically connected to the control assembly 500, and the tool changing assembly 200 is configured to load a plurality of tools 600 and can rotate relative to the housing 100.

[0076] Specifically, the tool changing assembly 200 is used to change the tool 600. The tool changing assembly 200 is disposed on the housing 100, that is, it can be disposed inside the housing 100 or outside the housing 100. Figure 2As shown, the tool changing assembly 200 is located at the exit of the housing 100 and at the left side (i.e., the front) of the push-clamp assembly 300, so that when the clamp 340 of the push-clamp assembly 300 moves from right to left to the working position, the clamp 340 can directly clamp the tool 600. In the present application, the tool changing assembly 200 is adopted so that the tool 600 can not only be replaced, but also can be directly inserted and clamped during the movement of the clamp 340 in accordance with the position of the push-clamp assembly 300, without manually clamping the tool 600, making the function of the device more diversified, and the structure of the tool changing assembly 200 can be set according to actual needs.

[0077] It should be noted that when the tool changing assembly 200 is set, the working position of the clamp 340 means that the clamp 340 clamps the tool 600 in the tool changing assembly 200 and extends out of the tool changing assembly 200. At the same time, when the clamp 340 reaches the working position, the clamp 340 is connected to the rotating clamp assembly 400.

[0078] Further, see Figures 1 to 5 As shown, in another embodiment of the present application, the tool changing assembly 200 includes a cutter disc 220 and a driving component 210, the cutter disc 220 is rotatably disposed on the housing 100, a plurality of channels 222 are disposed on the cutter disc 220, and the plurality of channels 222 are used to insert the tool 600, and any of the channels 222 can be rotated to a position aligned with the fixture 340; the driving component 210 is disposed in the housing 100 and connected to the cutter disc 220, and the driving component 210 is electrically connected to the control component 500.

[0079] Specifically, the present application provides a specific structure of a tool changing assembly 200, which includes a cutter disc 220 and a driving component 210. The cutter disc 220 is located on the left side of the housing 100. A plurality of channels 222 are provided on the cutter disc 220. Any channel 222 can be rotated to a position aligned with the fixture 340 to ensure that the fixture 340 and the tool 600 in any channel 222 can be aligned, so that the fixture 340 can be conveniently inserted into the clamping tool 600. It is worth noting that the number of channels 222 of the cutter disc 220 can be set according to actual needs. The driving component 210 is installed on the left side of the housing 100, and the driving component 210 is connected to the cutter disc 220, so that the cutter disc 220 can be driven to rotate to achieve the replacement of the tool 600. In the present application, the cutter disc 220 is rotated by the driving component 210, thereby driving the cutter 600 loaded in the channel 222 of the cutter disc 220 to rotate, and then cooperating with the rotating clamp assembly 400 and the pushing clamp assembly 300, so that the device can realize the switching of the cutter 600, and the functions are more diversified.

[0080] For example, Figure 3As shown, the number of channels 222 is preferably six, the angles between each channel 222 are 60 degrees, each channel 222 is loaded with a tool 600, and the tools 600 installed in each channel 222 are different.

[0081] See also Figure 2 As shown, in another embodiment of the present application, the driving component 210 includes a driving servo 211 and a threaded rod 212. The driving servo 211 is arranged in the housing 100 and is electrically connected to the control component 500; the threaded rod 212 is arranged on the output shaft of the driving servo 211 and is threadedly connected to the cutter disc 220.

[0082] Specifically, the driving servo 211 is installed in the housing 100 and is located on the left side of the transmission shaft 422. This arrangement can make full use of the space in the housing 100. The output shaft of the driving servo 211 is installed with the threaded rod 212. A through hole 221 is set in the middle of the cutter disc 220. The threaded rod 212 and the through hole 221 are threadedly matched, so that the cutter disc 220 can be fixed on the threaded rod 212. It should be noted that a certain length is reserved between the through hole 221 of the cutter disc 220 and the threaded rod 212. This arrangement is conducive to adjusting the position of the cutter disc 220 on the threaded rod 212, and then adjusting the position of the cutter disc 220 in the housing 100, so that the extension length of the clamp 340 is adjustable, and then the extension length of the tool 600 is adjusted, which is more convenient to use.

[0092] Specifically, the insertion slot is magnetically connected to the tool 600 , and by providing the insertion slot and the tool 600 with a magnetic connection, the connection stability between the clamp 340 and the tool 600 is ensured.

[0093] Furthermore, the shape of the insertion groove is set to be hexagonal, and the shape of the insertion portion of the tool 600 is also set to be hexagonal, and the hexagonal connection method is used to prevent the tool 600 from rotating on the fixture 340.

When the positioning block 2205 is installed, the through hole 221 in the cutter disc 220 does not need to be provided with threads, and then the positioning block 2205 is fixed on the positioning groove 22023, so that it is only necessary to provide threads matching the threaded rod 212 on the positioning block 2205, and the positioning block 2205 is threadedly connected with the threaded rod 212, so that the structure of the cutter disc 220 can be simplified, and the through hole 221 of the cutter disc 220 does not need to be processed with threads, which can reduce the manufacturing cost to a certain extent.

[0100] In another embodiment of the present application, a bracket is disposed in the housing 100 , and the transmission shaft 422 is mounted on the bracket, so that the transmission shaft 422 can stably rotate in the housing 100 .

[0101] In another embodiment of the present application, the control component 500 is a main control board, and the corresponding control program is preset using the Arduino UNO open source software platform to control each component.

[0102] In another embodiment of the present application, heat dissipation holes are provided on both sides of the housing 100 for dissipating heat from various components.

[0103] See also Figure 2 As shown, in another embodiment of the present application, a power supply module is disposed in the housing 100 , and the power supply module is electrically connected to the control component 500 .

[0104] Specifically, the power supply module is a battery, which is electrically connected to the control component 500. The power supply module supplies power to the control component 500, and then the control component 500 supplies power to the push-clamp component 300, the rotating clamp component 400 and the tool changing component 200 through controlling the power supply module. The setting of the power supply module makes it less likely to limit the use of the device.

[0105] In another embodiment of the present application, a tool 600 number sensor and a display module are provided on the shell 100, and the tool 600 number sensor and the display module are electrically connected to the control component 500; the tool 600 number sensor is used to detect the number of the tool 600 at the corresponding position of the fixture 340, and the display module is used to display the numbers of all tools 600 and the model identification of the tool 600 at the corresponding position of the fixture 340.

[0106] Specifically, in the present application, the tool 600 numbering sensor refers to a sensor for detecting the position of the tool 600 of the cutter disc 220. For example, the tool 600 numbering sensor may be an angle sensor. The user numbers the various tools 600 in the channel 222 of the cutter disc 220 in advance, such as No. 1, No. 2, No. 3, No. 4, No. 5, and No. 6, etc. The initial tool 600 is No. 1, and the target tool 600 is No. 5. When the user gives the cutter disc 220 an instruction to reach the target tool No. 6005, the control component 500 parses the instruction to control the driving servo 211 to rotate so as to drive the cutter disc 220 to rotate. When the cutter disc 220 reaches the target tool No. 6005, the angle sensor is fed back to the control component 500 again, and the control component 500 stops rotating the driving servo 211 to stop rotating the cutter disc 220. In this way, the number of the tool 600 can be displayed in real time in cooperation with the display module.

[0107] It should be noted that the display module is a touch display screen, and the model identification of the tool 600 refers to the model parameters of the tool 600. For example, the tool 600 is a cross screw tool 600 and a slotted screw tool 600, etc. These model identifications can be pre-set in the display module. When the current tool 600 of the tool disk 220 rotates to the target tool 600, the display module displays the number of the tool 600 corresponding to the fixture 340. A touch command of the model identification of the tool 600 is pre-set next to the tool 600 number on the display module. The user can jump to the display interface of the model identification of the tool 600 by clicking the touch command of the model identification next to the tool 600 number, or the tool 600 number is set as a touch command, and the user can jump to the display interface of the model identification of the tool 600 by clicking the tool 600 number, so that the user can understand the model parameters of the tool 600 more clearly.

[0108] Based on all the above embodiments, the working principle of this application is as follows:

[0109] The control component 500 receives the user's work control instruction. The control component 500 first controls the push-clamp servo 350 to start. The push-clamp servo 350 drives the screw rod 320 to rotate to drive the slider 330 to move to the left. The slider 330 drives the fixture 340 to move into the channel 222 of the tool disc 220. At this time, the fixture 340 is inserted into the tool 600, and the insertion groove of the fixture 340 is magnetically connected to the insertion part of the tool 600, and the tool 600 is fixed on the fixture 340; then continue to move the slider 330 to drive the tool 600 on the fixture 340 to move out of the first channel 2221, and make the tool 600 on the fixture 340 located in the working position, the fourth bevel gear 425 on the fixture 340 is connected to the third bevel gear 424 of the transmission shaft 422, and finally start the rotating clamp servo 410 to drive the fixture 340 to rotate, so as to drive the tool 600 on the fixture 340 to rotate and work.

[0110] The control component 500 receives the user's stop control command, controls the rotating clamp servo 410 to stop working, and then controls the pushing clamp servo 350 to start, the pushing clamp servo 350 drives the screw rod 320 to rotate to drive the slider 330 to move to the right, and the slider 330 drives the clamp 340 to move to the initial position. When the limit plate 610 on the tool 600 abuts against the right end of the second channel 2222, the tool 600 is limited by the limit plate 610 and stuck in the second channel 2222, and the tool 600 The limit plate 610 is magnetically connected to the second channel 2222, so that the tool 600 is fixed at the right end of the second channel 2222. When the pulling force of the clamp 340 is greater than the suction force of the limit plate 610 and the second channel 2222, the clamp 340 is separated from the tool 600, and the tool 600 is unloaded in the tool disc 220. The clamp 340 moves out of the third channel 2223 and continues to control the rotating clamp servo 410 to rotate the screw rod 320 to drive the clamp 340 on the slider 330 to move to the initial position of the clamp 340.

[0111] The control component 500 receives the tool changing control instruction from the user, and the control component 500 parses the tool changing control instruction to obtain the number of revolutions that the driving servo 211 needs to rotate and the target tool 600. Then the control component 500 controls the driving servo 211 to drive the cutter disc 220 to rotate to the target tool 600. The angle sensor detects the rotation angle of the cutter disc 220 in real time. When the cutter disc 220 rotates to the target tool 600, the angle sensor feeds back to the control component 500. The control component 500 controls the driving servo 211 to stop rotating the cutter disc 220, completing the tool changing. Finally, the above steps are repeated to operate the cutter 600.

[0112] Based on any of the above multifunctional electric drills, see Figure 8 As shown, the present invention also provides a preferred embodiment of a control method for a multifunctional electric drill:

[0113] S100: Obtain a user's work control signal.

[0114] Specifically, the working control signal refers to the working signal sent by the user to the control component, and the working control signal can be obtained by the control component. For example, a trigger switch is installed on the housing, and the trigger switch is connected to the control component, so that when the user presses the trigger switch, the trigger switch sends the working control signal to the control component.

[0115] S200, controlling the pushing and clamping assembly to move the clamp according to the working control signal, so that the clamp clamps the tool, and the clamp reaches the working position, and the clamp is connected to the rotating clamp assembly.

[0116] Specifically, the user sends a work control signal to the control component, and the control component analyzes the work control signal to control the push clamp component to move the fixture. During the process of the fixture moving to the working position, the fixture clamps the tool. When the fixture reaches the working position, the fixture is connected to the transfer clamp component. It can be understood that the working position of the fixture at this time refers to the working position where the tool change component is set.

[0117] Furthermore, the control component determines the number of rotations of the push-clamp servo according to the working control signal, thereby determining the number of rotations of the screw rod, and then determining the moving distance of the slider on the screw rod, and the moving distance refers to the distance from the initial position to the working position of the fixture; the control component controls the push-clamp servo to start, driving the slider on the screw rod to move, and the slider drives the fixture to move to the working position, the fixture clamps the current tool in the tool disc, and makes the fourth bevel gear on the fixture mesh with the third bevel gear of the transmission shaft.

[0118] S300, controlling the rotating clamp assembly to rotate the clamp to drive the tool to work.

[0119] Specifically, since the clamp is connected to the rotating clamp assembly, at this time, the control assembly controls the rotating clamp assembly to rotate, and the rotating clamp assembly can rotate the clamp to drive the tool on the clamp to work.

[0120] Furthermore, the control component controls the rotation of the rotating clamp servo, the first bevel gear on the output shaft of the rotating clamp servo rotates, the first bevel gear engages with the second bevel gear to drive the transmission shaft to rotate, the third bevel gear engages with the fourth bevel gear, the transmission shaft drives the fixture to rotate, and the fixture drives the tool to work.

[0121] The working time of the tool is determined according to the working time signal.

[0122] Specifically, the multifunctional electric drill also includes a time timer, which is electrically connected to the control component. The working time signal means that the working time of the rotating clamp component is a fixed working time. When the control component receives the user's working control signal, the clamp moves to the working position, the clamp clamps the tool, and the clamp is connected to the rotating clamp component. The control component will send a fixed rotation working time to the rotating clamp component, and the rotating clamp component will drive the tool on the clamp to work for a fixed working time. The time timer is used to time the working time. When the actual working time reaches the fixed working time, the time timer feeds back to the control component, and the control component controls the rotating clamp component to stop rotating.

[0123] After step S300, the control method further includes:

[0124] S310, obtaining a knife stop control signal from a user.

[0125] Specifically, the stop control signal refers to stopping the rotation of the rotating clamp assembly, and the user sends the stop control signal to the control assembly. Exemplarily, a stop switch is provided on the housing, and the stop switch is electrically connected to the control assembly, so that the user can send the stop control signal to the control assembly through the stop switch.

[0126] S320, controlling the rotating clamp assembly to stop rotating the clamp according to the tool stopping control signal, so that the tool stops rotating.

[0127] Specifically, according to the tool stop control signal sent by the user, the control component controls the rotating clamp component to stop rotating the fixture so that the tool on the fixture stops rotating. This setting is conducive to moving the fixture and avoiding conflicts between the fixture and the rotating clamp component.

[0128] Furthermore, when the rotating clamp servo stops rotating, the third bevel gear of the transmission shaft will also stop rotating, and the fourth bevel gear of the clamp can be separated from the third bevel gear, thus avoiding the conflict between the third bevel gear and the fourth bevel gear and affecting the moving effect of the clamp.

[0129] S330, controlling the clamp pushing assembly to move the clamp to the initial position of the clamp, so that the tool is retracted and the tool is unloaded to the tool changing assembly.

[0130] Specifically, according to the tool stop control signal, the control component first controls the rotating clamp component to stop rotating the clamp to avoid obstructing the movement of the clamp during the rotation of the rotating clamp component. Then the control component controls the pushing clamp component to move the clamp to the initial position of the clamp. During this process, the tool is first retracted into the tool changing component, and finally the tool is removed from the tool changing component. In this way, the next time the clamp is used, you only need to repeat the above steps of obtaining the user's work control signal, without the need to remove the tool again, which provides more convenience for users.

[0131] Before step S100, or after step S330, the control method further includes:

[0132] A10. Obtain the tool change control signal from the user and determine the target tool.

[0133] Specifically, the user sends a tool-changing control signal to the control component, and the control component parses the tool-changing control signal. The tool-changing control signal refers to a tool-changing signal of a target tool. When the user sends the tool-changing control signal, the target tool can be determined.

[0134] A20. According to the tool changing control signal, gradually rotate the tool changing assembly so that the position of the target tool corresponds to the position of the fixture.

[0135] Specifically, the tool change control signal is sent to the control component, and the control component can gradually rotate the tool change component so that the position of the target tool corresponds to the position of the fixture.

[0136] Furthermore, the control component controls the cutter disc to rotate step by step, with each rotation being a tool distance, so that the current tool of the cutter disc rotates to the target tool.

[0137] Exemplarily, a tool change switch is provided on the housing, and the tool change switch is pre-set to the angle of each tool rotation of the tool disc, and the tool change switch is electrically connected to the control component. The target tool is determined by the user, and the user observes the position of the target tool on the tool disc, and finally determines the number of times to press the tool change switch according to the position of the target tool, so as to control the driving component to drive the tool disc to rotate, and rotate the current tool of the tool disc to the target tool. It should be noted that the tool change can be performed before the tool starts working, or after the tool starts working.

[0138] The tool change control signal includes a first tool change control signal and a second tool change control signal;

[0139] The step A20 specifically includes:

[0140] A21. According to the first tool-changing control signal, control the tool-changing assembly to rotate clockwise so that the position of the target tool corresponds to the position of the fixture, or;

[0141] A22. According to the second tool-changing control signal, control the tool-changing assembly to rotate counterclockwise so that the position of the target tool corresponds to the position of the fixture.

[0142] Specifically, the user can select step A21 and step A22 according to actual needs. The user can select one of them according to actual needs to achieve the correspondence between the position of the target tool and the position of the tool.

[0143] Exemplarily, a clockwise switch and a counterclockwise switch are provided on the housing, and both the clockwise switch and the counterclockwise switch are electrically connected to the control assembly. The clockwise switch corresponds to the first tool change control signal, and the counterclockwise switch corresponds to the second tool change control signal. The clockwise switch and the counterclockwise switch are both set to rotate the angle of one tool. More specifically, a plurality of tools are loaded in the tool disc, and the tool disc has six channels, and six tools are loaded correspondingly, numbered 1, 2, 3, 4, 5, and 6. The current tool is No. 1, and the target tool is No. 5. When the user presses the clockwise switch, it needs to be rotated four times to reach the target tool. When the user presses the counterclockwise switch, it needs to be rotated twice to reach the target tool. It can be obtained that by setting the first tool change control signal and the second tool change control signal, the tool disc can be quickly rotated to the target tool, providing more convenience for the user.

[0144] The control method further comprises:

[0145] S410: Obtain a reset control signal from a user.

[0146] Specifically, the reset control signal is sent by the user to the control component. For example, a reset switch is provided on the housing, and the reset switch is electrically connected to the control component. The user can send the reset control signal to the control component by pressing the reset switch.

[0147] S420, controlling the driving component to rotate the cutter disc to an initial position of the cutter disc according to the reset control signal.

[0148] Specifically, the control component receives a reset control signal and then controls the driving component to rotate the cutter disc to an initial position of the cutter disc. The initial position of the cutter disc refers to the corresponding position of the tool and the fixture in the cutter disc when the cutter disc has not been rotated. The reset control signal is used to facilitate the user's next use.

[0149] Before step S100, the control method further includes:

[0150] S10: Obtain a power-on control signal from a user.

[0151] Specifically, the user sends a power-on control signal to the control component, and the power-on control signal can be implemented through a power-on switch.

[0152] S20, controlling the power supply of the tool changing assembly, the clamp pushing assembly and the clamp rotating assembly according to the power-on control signal.

[0153] Specifically, the control component controls the power supply module to supply power to the tool change component, the push clamp component and the rotating clamp component, so that the tool change component, the push clamp component and the rotating clamp component can be preheated, the failure rate is reduced, and the device can operate smoothly. More specifically, the power switch includes a tool change power switch, a push clamp power switch and a rotating clamp power switch, and the tool change power switch, the push clamp power switch and the rotating clamp power switch are all electrically connected to the control component, the tool change power switch is used to control the power supply of the tool change component, the push clamp power switch is used to control the power supply of the push clamp component, and the rotating clamp power switch is used to control the power supply of the rotating clamp component.

[0154] Furthermore, the multifunctional electric drill also includes a tool-changing current sensor, a clamp-pushing current sensor, and a clamp-switching current sensor, which are all electrically connected to the control component. The tool-changing current sensor is used to detect the actual current of the driving servo, the clamp-pushing current sensor is used to detect the actual current of the clamp-pushing servo, and the clamp-switching current sensor is used to detect the actual current of the clamp-switching servo. When the actual current differs greatly from the preset rated current of each device, the control component issues a reminder to remind the user that there may be problems in the clamp-switching servo, the driving servo, and the clamp-pushing servo, so as to facilitate timely maintenance.

[0155] The present application also provides a control system for a multifunctional electric drill, comprising a memory and a processor, wherein the memory stores a computer program, and the processor implements the steps of any one of the control methods described above when executing the computer program.
