Description
Technical Field
[0001] This utility model relates to the field of drilling device technology, and in particular to an intelligent CNC silent drilling electric tool. Background Technology
[0002] A drilling device is a mechanical tool that uses rotation or impact motion to process round holes in solid materials. Its core components include a power head, a drill chuck, and a drill bit. According to the driving method, it can be divided into electric, hydraulic, pneumatic, and other types.
[0003] Taking electric drilling devices as an example, their working principle is based on the high-speed rotation and axial feed of the drill bit. The material is peeled off layer by layer by the cutting edge to form a hole. Rotary drilling machines rely on the motor to drive the drill rod to transmit torque, thereby completing the drilling at the designated location. Modern equipment often combines rotation and impact actions and uses coolant to reduce frictional heat, thereby improving drilling accuracy and efficiency.
[0004] Existing drilling equipment typically uses a feed mechanism to control the movement of the drilling component, which then drills at a designated location. However, existing drilling components lack an emergency braking mechanism in case of power failure or malfunction. Relying solely on a motor and electromagnetic brake for self-locking poses a reliability risk. In the event of an emergency power outage or other circumstances causing the drilling component to fall, there is no effective way to stop its descent, which could damage the drill bit or internal parts of the drilling component, making it inconvenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent CNC silent drilling power tool, comprising: A control chassis, a touch control chassis is provided on one side of the control chassis, a movable chassis is provided on one side of the control chassis, a feeding component is provided between the movable chassis and the control chassis, and a limit frame is provided on the side of the feeding component near the movable chassis; A locking assembly is disposed on the lower surface of the mobile chassis. The locking assembly includes a mounting plate fixedly mounted on the lower surface of the mobile chassis. A movable seat is disposed on the side of the mounting plate near the locking frame. A compression spring is installed between the movable seat and the mounting plate. A fixed magnet is installed on the side of the mounting plate near the movable seat. An electromagnet is installed on the lower surface of the movable seat. A fixed toothed plate is installed on the outer surface of the limiting frame near the movable seat. A locking plate is installed on the side of the movable seat near the fixed toothed plate. A drilling assembly is disposed inside a mobile chassis. The drilling assembly includes a mounting base installed inside the mobile chassis, a rotating cylinder mounted inside the mounting base via a bearing, a sound-absorbing column installed inside the mobile chassis and inserted into the mounting base, and a sound-absorbing block installed inside the mobile chassis.
[0007] As a preferred embodiment of the intelligent CNC silent drilling electric tool described in this utility model, a speed sensor is installed on the top of the feed component, and a control module is installed inside the control housing.
[0008] As a preferred embodiment of the intelligent CNC silent drilling electric tool described in this utility model, the outer surface of the locking plate is provided with teeth that cooperate with the fixed tooth plate, and the outer surface of the locking plate is provided with an arc-shaped groove that cooperates with the limiting frame.
[0009] As a preferred embodiment of the intelligent CNC silent drilling power tool described in this utility model, a limiting plate is installed on the side of the mounting plate near the moving seat, and two limiting rods are installed on the side of the mounting plate near the moving seat. The moving seat has an insertion hole inside, and the limiting rod passes through the inside of the compression spring and is inserted into the insertion hole.
[0010] As a preferred embodiment of the intelligent CNC silent drilling power tool described in this utility model, a geared motor is installed on the outer surface of the mobile housing, and synchronous pulleys are installed on the output end of the geared motor and the outer surface of the mounting cylinder. A synchronous belt is connected between the two synchronous pulleys. Anti-detachment discs are installed on the output end of the geared motor and on the top and bottom of the synchronous pulleys of the rotating cylinder.
[0011] As a preferred embodiment of the intelligent CNC silent drilling electric tool described in this utility model, the sound-absorbing block has protrusions on both sides inside, the sound-absorbing block abuts against the side of the mounting base through the protrusions, and the inner side of the sound-absorbing block has an arc-shaped surface.
[0012] This utility model provides an intelligent CNC silent drilling power tool. It has the following beneficial effects: 1. By using a speed sensor, electromagnet, fixed magnet, compression spring, moving base, locking plate, and fixed toothed plate, the electromagnet is de-energized when the mobile chassis falls, causing it to separate from the fixed magnet. The moving base, under the reset action of the compression spring, drives the locking plate to reset, allowing the locking plate to engage with the fixed toothed plate to lock and prevent damage from the falling mobile chassis.
[0013] 2. By incorporating a geared motor, synchronous pulley, synchronous belt, rotating drum, mounting base, sound-absorbing column, and sound-absorbing block, the geared motor controls the rotation of the rotating drum and the drill bit at the bottom of the rotating drum. The sound-absorbing column connects to the mounting base, and the sound-absorbing block abuts against the side of the mounting base, absorbing vibrations and reducing noise. Furthermore, the curved surface of the inner side of the sound-absorbing block allows noise emitted from the internal components of the moving housing to be refracted back, thus canceling out noise and further reducing noise levels, achieving a quiet operation.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1
[0022] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention, which provides an intelligent CNC silent drilling power tool, comprising: A control box 2 is provided. A touch box 1 is provided on one side of the control box 2. A movable box 4 is provided on one side of the control box 2. A feeding component 3 is provided between the movable box 4 and the control box 2. A limit frame 7 is provided on the side of the feeding component 3 near the movable box 4. Locking assembly 5 is disposed on the lower surface of the mobile housing 4. Locking assembly 5 includes a mounting plate 501 fixedly mounted on the lower surface of the mobile housing 4. A movable seat 510 is disposed on the side of the mounting plate 501 near the locking frame. A compression spring 506 is installed between the movable seat 510 and the mounting plate 501. A fixing magnet 508 is installed on the side of the mounting plate 501 near the movable seat 510. An electromagnet 505 is installed on the lower surface of the movable seat 510. A fixing toothed plate 502 is installed on the outer surface of the limiting frame 7 near the movable seat 510. A locking plate 503 is installed on the side of the movable seat 510 near the fixing toothed plate 502.
[0023] like Figure 1 as well as Figure 2 In this embodiment, a speed sensor 504 is installed on the top of the feed component 3, and a control module is installed inside the control box 2. The control module is electrically connected to the touch box 1, the speed sensor 504, the feed component 3, and the drilling component through wires. The touch box 1 is convenient to operate, and the control module inside the control box 2 controls the operation of the entire device.
[0024] like Figure 2 as well as Figure 3 In this embodiment, the outer surface of the locking plate 503 is provided with teeth that cooperate with the fixed toothed plate 502, and the outer surface of the locking plate 503 is provided with an arc-shaped groove that cooperates with the limiting frame 7. Through the cooperation between the locking plate 503 and the fixed toothed plate 502, the locking plate 503 can cooperate with the fixed toothed plate 502, thereby preventing the displacement motor box 4 from falling. The arc-shaped groove is provided so that the locking plate 503 can cooperate with the limiting frame 7, avoiding interference between the limiting frame 7 and the locking plate 503 and preventing the locking plate 503 from cooperating with the fixed toothed plate 502.
[0025] like Figure 3In this embodiment, a limiting plate 507 is installed on the side of the mounting plate 501 near the movable seat 510, and two limiting rods 509 are installed on the side of the mounting plate 501 near the movable seat 510. The movable seat 510 has an insertion hole inside, and the limiting rods 509 pass through the inside of the compression spring 506 and are inserted into the insertion hole. A limiting groove is opened on the outer surface of the limiting plate 507, and a limiting slide groove is opened on the top of the movable seat 510 to cooperate with the limiting plate 507. The movable seat 510 slides on the outer surface of the limiting plate 507 through the cooperation of the limiting groove and the limiting slide groove. The limiting rods 509 limit the compression spring 506 and prevent the compression spring 506 from deviating.
[0026] Furthermore, a support plate is provided at the bottom of the control box 2, and a horizontal plate is installed on the top of the control box. The feed component 3 and the limit frame 7 are both installed between the support frame and the horizontal plate. The feed component 3 controls the lifting and lowering of the moving machine box 4, and the vertical lifting and lowering of the moving machine box 4 is limited by the cooperation of the limit frame 7 and the moving machine box 4. A locking module is provided inside the rotating cylinder 605 to lock the installed drill bit. The feed component 3 includes components such as a lead screw, a drive motor, and transmission gears. The top of the lead screw passes through the inside of the horizontal plate and is connected to the speed sensor. The speed sensor is electrically connected to the control module inside the control box 2. In the event of a sudden power failure... If the feed component 3 malfunctions and causes abnormal rotation, a signal is transmitted through the speed sensor, which in turn controls the power off through the control module. This prevents the electromagnet 505 from continuing to attract and fix the magnet 508 after the power is cut off. At this time, under the reset action of the compression spring 506, the moving seat 510 drives the locking plate 503 to reset, so that the locking plate 503 cooperates with the fixed toothed plate 502 to achieve locking and prevent the moving chassis 4 from falling and causing damage. The connection relationship, working principle and operation sequence between the locking module, feed component 3, speed sensor and other components are existing technologies and are common knowledge known to those skilled in the art. They will not be elaborated on here. Example 2
[0027] Reference Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment. The drilling assembly 6 is disposed inside the mobile housing 4. The drilling assembly 6 includes a mounting base 603 installed inside the mobile housing 4. A rotating cylinder 605 is mounted inside the mounting base 603 via a bearing. A sound-absorbing column 604 is installed inside the mobile housing 4 and is inserted into the mounting base 603. A sound-absorbing block 608 is installed inside the mobile housing 4.
[0028] like Figure 4 as well as Figure 5In this embodiment, a geared motor 601 is installed on the outer surface of the mobile housing 4. Synchronous pulleys 602 are installed on the output end of the geared motor 601 and the outer surface of the mounting cylinder. A synchronous belt 606 is connected between the two synchronous pulleys 602. Anti-detachment discs 607 are installed on the output end of the geared motor 601 and the rotating cylinder 605 at the top and bottom of the synchronous pulleys 602. By setting the anti-detachment discs 607, the synchronous belt 606 is limited to prevent it from disengaging from the synchronous pulleys 602, thus ensuring good transmission.
[0029] like Figure 5 In this embodiment, the sound-absorbing block 608 has protrusions on both sides inside. The sound-absorbing block 608 abuts against the side of the mounting base 603 through the protrusions. The inner side of the sound-absorbing block 608 has an arc-shaped surface 609. By setting the arc-shaped surface 609 on the inner side of the sound-absorbing block 608, the noise generated by the synchronous belt 606 and the bearing inside the mounting base 603 can be reflected inside the moving housing 4, so that the noise cancels each other out, thereby reducing the noise.
[0030] Furthermore, both the sound-absorbing column 604 and the sound-absorbing block 608 are made of materials with high damping characteristics, including but not limited to rubber and polyurethane. The sound-absorbing column 604 is inserted into the mounting base 603, and the sound-absorbing block 608 abuts against the side of the mounting base 603, thereby absorbing the vibrations generated by the bearings inside the mounting base 603 and the rotating cylinder 605 during operation, thus reducing noise. The geared motor 601, through the cooperation of the synchronous pulley 602 and the synchronous belt 606, drives the rotating cylinder 605 to rotate, thereby driving the drill bit to rotate. When the rotating cylinder 605 rotates… The mounting base 603, through the cooperation of the bearing and the rotating cylinder 605, provides auxiliary support for the rotating cylinder 605. During rotation, the resulting vibration causes the mounting base 603 to vibrate. The sound-absorbing column 604 is inserted into the mounting base 603, and the sound-absorbing block 608 abuts against the side of the mounting base 603, thus absorbing vibration and reducing noise. Furthermore, the arc-shaped surface 609 on the inner side of the sound-absorbing block 608 allows the noise emitted by the internal components of the mobile chassis 4 to be refracted back, thereby canceling out the noise and further reducing the noise, thus achieving a silent effect.
[0031] Working principle: When drilling at a designated location, the drill bit is installed at the bottom of the rotating drum 605. Then, the geared motor 601 is started. The geared motor 601 drives the rotating drum 605 to rotate through the cooperation of the synchronous pulley 602 and the synchronous belt 606, thereby driving the drill bit to rotate. When the rotating drum 605 rotates, the mounting base 603 provides auxiliary support to the rotating drum 605 through the cooperation of the bearing. The vibration generated during the rotation drives the mounting base 603 to vibrate. Through the insertion of the sound-absorbing column 604 into the mounting base 603 and the sound-absorbing block 604, the vibration is controlled. The contact between the sound-absorbing block 608 and the side of the mounting base 603 absorbs vibration and reduces noise. Furthermore, the arc-shaped surface 609 on the inner side of the sound-absorbing block 608 allows noise emitted from the internal components of the moving housing 4 to be refracted back, thus canceling out noise and further reducing noise, achieving a silent effect. Once the drill bit starts rotating, the feed component 3 is activated, driving the moving housing 4 to move. When the entire device is operating normally, the electromagnet 505 is powered normally, causing it to attract the fixed magnet 508, thereby moving the moving base 510 towards... The side closer to the fixed plate moves, thereby causing the locking plate 503 to separate from the fixed toothed plate 502, allowing the moving housing 4 to rise and fall normally. In the event of a sudden power outage, the electromagnet 505 will be de-energized. At this time, under the reset action of the compression spring 506, the moving seat 510 will drive the locking plate 503 to reset, thereby allowing the locking plate 503 to engage with the fixed toothed plate 502, thus achieving locking and preventing the moving housing 4 from falling and causing damage. If there is no sudden power outage, but rather a malfunction in the feeding component 3, the moving housing 4 will fall under the action of gravity. During drilling, to protect the drill bit, the feed unit 3 usually controls the moving housing 4 to move slowly downwards. This is common knowledge and will not be elaborated on here. When the feed unit 3 malfunctions and cannot effectively control the moving housing 4 to move slowly downwards, the downward movement of the moving housing 4 reverses and drives the lead screw to rotate rapidly. This causes the speed sensor 504 to sense the abnormal speed of the lead screw, thereby cutting off the power supply to the housing 2, which in turn de-energizes the electromagnet 505. The same steps are used to lock the moving housing 4, preventing it from falling and being damaged, and finally completing the drilling work.
[0032] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
