Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To address the problem of low workpiece processing efficiency in existing technologies, this invention provides a rotatable hole-making device, comprising: a turntable clamping assembly 1, a feed machining assembly 2, and a control console 3; the turntable clamping assembly 1 includes a turntable 101 and a turntable base 102, the turntable 101 being mounted on the turntable base 102 and electrically connected to the control console 3; the feed machining assembly 2 includes a support frame, an adjustable track, and a hole-making tool, the adjustable track being fixed on the support frame, the hole-making tool being mounted on the adjustable track, the hole-making tool being electrically connected to the control console 3 and capable of vertical and horizontal movement along the adjustable track.

[0021] The turntable clamping assembly 1 is used to support and position the workpiece to be processed. The assembly includes two parts: a turntable 101 and a turntable base 102. The turntable base 102 serves to fix and support the turntable 101, ensuring its stability and rotational accuracy during operation. The turntable 101 is mounted on the turntable base 102 and is supported by a central shaft to achieve rotation around its own axis. It is electrically connected to the control console 3 so that automatic rotation control can be achieved through electrical control signals.

[0022] The feed machining assembly 2 is the main mechanism for performing drilling, reaming, and other machining operations. This assembly includes a support frame, an adjustable track, and a drilling tool. The support frame, as the main structural component, is used to fix the track and provide a stable guiding foundation for the movement of the drilling tool. The adjustable track is mounted on the support frame and can provide precise guiding control in the vertical and horizontal directions, enabling the drilling tool to achieve multi-dimensional movement. The drilling tool is set on the adjustable track and is electrically connected to the control console 3. Driven by the electrical signal output from the control console 3, it can achieve vertical or horizontal feed along the adjustable track, thereby performing hole machining on the workpiece surface at different positions.

[0023] As an optional implementation, the support frame includes: a base plate 202, a top plate 201 and a support plate 203; the support plate 203 is disposed between the base plate 202 and the top plate 201.

[0024] The base plate 202 supports the entire feed machining assembly 2 and is connected to the fixed foundation of the device to ensure overall stability and vibration resistance. For example, the base plate 202 and the turntable base 102 are both connected to the same worktable 4. The top plate 201 serves as the upper load-bearing surface and, together with the base plate 202, forms the support plate 203 structure. The support plate 203 is positioned between the base plate 202 and the top plate 201, serving to connect, reinforce, and position the components, forming a rigid frame structure between the base plate 202 and the top plate 201. The support plate 203 is used to connect the adjustable track and the drilling tool.

[0025] In this structure, the support plates 203 can be arranged in parallel or in a frame structure, and their number and position can be optimized according to the actual force distribution. The support plates 203 support the feed processing component 2, which facilitates the installation of guide rails, transmission screws 205 and related drive mechanisms, making the overall layout more compact and conducive to modular design and later maintenance of the device.

[0026] As an optional implementation, the support plate 203 includes a first sub-support plate 2033 and a second sub-support plate; the first sub-support plate 2033 and the second sub-support plate form a triangular support structure.

[0027] The first sub-support plate 2033 is set perpendicularly or inclined to the bottom plate 202, and the second sub-support plate is connected to the top plate 201, forming a certain angle with the first sub-support plate 2033. Together, they form a triangular force-bearing unit, thereby enhancing the overall rigidity and deformation resistance of the support frame. This triangular support structure has good mechanical stability. In addition, the triangular support structure can also be fixed by welding, bolts or reinforcing ribs. According to the processing accuracy requirements, the first sub-support plate 2033 and the second sub-support plate can be arranged symmetrically to achieve overall balance and uniform mechanical distribution.

[0028] As an optional implementation, the first sub-support plate 2033 is connected to the adjustable track; the second sub-support plate includes support bars 2031 and reinforcing plates 2032. There are two support bars 2031, the top of each support bar 2031 is connected to the top plate 201, and the bottom is connected to the bottom plate 202. The reinforcing plate 2032 is disposed between the two support bars 2031.

[0029] The first sub-support plate 2033 is connected to the adjustable track to provide a stable mounting base for the adjustable track. This connection method ensures that the adjustable track maintains parallelism and rigid support during the feeding of the drilling tool, preventing track deviation due to machining loads or vibrations, thereby improving drilling accuracy and stability.

[0030] The second sub-support plate includes support bars 2031 and reinforcing plates 2032. There are two support bars 2031, each of which is connected to the top plate 201 at its top and to the bottom plate 202 at its bottom, forming a longitudinal force channel to bear the vertical load generated by the adjustable track and the movement of the drilling tool. The reinforcing plate 2032 is located between the two support bars 2031, and its two ends are fixedly connected to the two support bars 2031 respectively, forming a closed reinforcing frame structure.

[0031] As an optional implementation, the adjustable track includes a longitudinal guide rail 204, a lead screw 205, a slide 206, and a main shaft fixing plate 207; there are two longitudinal guide rails 204, which are respectively located near the two sides of the support frame; the lead screw 205 is located in the middle of the two longitudinal guide rails 204 and is controlled by a lead screw motor 208 located at the top of the support frame; the slide 206 cooperates with the longitudinal guide rails 204 and the lead screw 205 and can move along the longitudinal guide rails 204; the main shaft fixing plate 207 is movably connected to the slide 206.

[0032] The longitudinal guide rails 204 are paired linear guide components, with two in total, located on both sides of the support frame. This symmetrical arrangement forms a stable double-guide support structure, ensuring that the slide 206 is subjected to uniform force and maintains a stable posture during movement, thereby effectively preventing tilting or shaking caused by unilateral force.

[0033] The lead screw 205 is located in the middle of the two longitudinal guide rails 204 and serves as the active transmission element for the feed of the slide 206. The lead screw 205 is connected to the lead screw motor 208 located at the top of the support frame via a coupling. When the lead screw motor 208 is started, the rotational motion output by the motor is converted into linear displacement by the lead screw 205, thereby driving the slide 206 to perform vertical feed along the longitudinal guide rails 204.

[0034] The slide plate 206 is installed in conjunction with the guide rail and the lead screw 205. The sliding surface is in contact with the guide rail slider and is threadedly engaged with the lead screw 205 through the nut seat, thus allowing it to move smoothly in a straight line along the guide rail under the drive of the motor. The spindle fixing plate 207 is installed on the slide plate 206 and can move horizontally on the slide plate 206. It also carries the drilling tool, ensuring that the movement path of the tool is consistent with the direction of the guide rail.

[0035] As an optional implementation, the adjustable track also includes a slide motor 209, which is mounted on the slide 206 and connected to the main shaft fixing plate 207. The slide motor 209 can drive the main shaft fixing plate 207 to move in the horizontal direction.

[0036] The slide motor 209 is mounted on the slide 206 and connected to the spindle fixing plate 207. This connection can be rigid or achieved through transmission components (such as couplings, sliding mechanisms, etc.) to ensure the synchronicity and stability of power transmission. When the slide motor 209 starts, its output rotational motion is converted into linear motion through the transmission mechanism, thereby driving the spindle fixing plate 207 and the drilling tool mounted on it to feed smoothly in the horizontal direction.

[0037] The slide motor 209 is typically a servo motor or a stepper motor, which can precisely control the displacement distance and feed speed according to the instructions issued by the console 3.

[0038] As an optional implementation, the drilling tool includes a drill bit 210 and a drill motor 211; the drill motor 211 is mounted on the spindle fixing plate 207 and drives the drill bit 210 to rotate.

[0039] The drill motor 211, serving as the power source, is mounted on the spindle mounting plate 207 and fixedly connected by bolts or locating pins to ensure that the motor axis is aligned with the drilling direction. The output shaft of the drill motor 211 is coaxially connected to the shank of the drill bit 210, typically secured using a flexible coupling, locking chuck, or quick-change tool holder to ensure transmission accuracy and ease of assembly and disassembly. After the motor starts, it drives the drill bit 210 to rotate at high speed, causing the cutting edge of the drill bit 210 to cut the workpiece surface, thereby achieving machining processes such as hole making, hole reaming, or chamfering.

[0040] The drill bit motor 211 is preferably a servo motor or a high-speed DC motor, which can achieve continuous speed adjustment under the command of the CNC operation console 3. By controlling the motor speed, the cutting speed and feed rate can be flexibly adjusted according to different materials and hole diameter requirements, thereby ensuring processing efficiency while avoiding problems such as hole wall burning and chipping.

[0041] As an optional implementation, the drill bit motor 211, the lead screw motor 208, and the slide motor 209 are all connected to the control console 3.

[0042] The control console 3, as the core control unit of this device, is equipped with a numerical control system or a programmable logic controller (PLC) to coordinate and precisely control the start, stop, speed, direction of motion, and displacement of each drive motor. The drill motor 211 drives the drill bit 210 to rotate, realizing hole cutting; the lead screw motor 208 drives the lead screw 205 to rotate, enabling the slide 206 and the spindle fixing plate 207 to feed vertically along the longitudinal guide rail 204; the slide motor 209 drives the spindle fixing plate 207 to move horizontally, realizing hole position switching or transverse machining.

[0043] As an optional implementation, the turntable clamping assembly 1 includes a hand crank 103; the hand crank 103 is connected to the turntable base 102 and can control the rotation of the turntable 101.

[0044] The hand crank 103 is mechanically connected to the turntable base 102, typically using a keyed connection, splined shaft connection, or threaded fastening structure to ensure stable transmission of rotational force to the turntable 101's rotating mechanism. When the operator rotates the hand crank 103, the rotational force is transmitted to the turntable 101 via the internal transmission structure of the turntable base 102 (such as a worm gear, gear set, or bearing housing), thereby enabling the turntable 101 to rotate precisely around its central axis. This structure allows for manual adjustment of the workpiece's angle and position even when the electrical control system is off or during manual calibration, offering advantages such as ease of operation and flexible positioning.

[0045] As an optional implementation, the turntable clamping assembly 1 includes a turntable controller 104; the turntable controller 104 is connected to the turntable base 102, the turntable 101 is electrically connected to the control console 3, and can drive the turntable 101 to rotate.

[0046] The rotary table controller 104 is mounted on the rotary table base 102 and connected to the rotary drive mechanism (such as a servo motor, stepper motor, or hydraulic rotary table) of the rotary table 101. The rotary table controller 104 receives motion command signals from the control console 3 through its built-in signal processing circuit or drive module, controlling the motor's start / stop, rotation direction, angular displacement, and speed. When the control console 3 issues a rotation command, the rotary table controller 104 drives the motor to precisely rotate the rotary table 101 around its central axis according to the set rotation angle parameters, causing the clamped workpiece to rotate to the specified machining angle or hole position.

[0047] The above technical solution has the following beneficial effects: Through the coordinated design of the turntable clamping assembly, feed machining assembly, and control console, automatic workpiece positioning and multi-angle hole making are achieved; the adoption of electronically controlled drive and a bidirectional adjustable track structure allows the hole-making tool to feed precisely in both vertical and horizontal directions, thus significantly improving machining accuracy and efficiency; the combination of the turntable controller and the hand crank enables the equipment to operate in both automatic and manual modes, making it flexible, safe, and reliable. In summary, this device has a compact structure, precise control, and high machining efficiency, significantly reducing manual labor intensity and improving the hole-making quality of batch workpieces.

[0048] The above-described specific embodiments of the invention further illustrate the purpose, technical solution, and beneficial effects of the invention. It should be understood that the above content is only for specific embodiments of the invention and is not intended to limit the scope of protection of the invention.
