Description

Technical Field

[0001] This utility model belongs to the field of milling plane machining, specifically relating to a milling machine for machining inclined planes. Background Technology

[0002] Inclined milling is a common task in metal processing, requiring specific conditions to be met between the workpiece, machine tool, and cutting tool. For example, the inclined surface of the workpiece must be parallel to the feed direction of the milling machine table during milling, and the inclined surface must match the cutting position of the milling cutter. There are three main methods for milling inclined surfaces: inclined workpiece milling, inclined cutter milling, and angled milling. Due to the complexity of inclined milling, conventional machine tools require manual adjustment of the milling cutter angle when encountering continuous inclined surfaces with different angles during processing, which can easily lead to accuracy deviations, such as inaccurate inclined surface angles and substandard surface roughness, making it difficult to guarantee the position and dimensions of the inclined surface relative to the bottom surface after machining. CNC machine tools can quickly and accurately adjust the milling cutter angle, but they are expensive and require specialized technicians.

[0003] A search revealed that invention CN102909403A discloses a device for machining inclined surfaces, comprising a disc with an inclination, a circular pad with the same inclination as the disc, and a soft claw. The soft claw is engaged with the disc and the circular pad. The outer plane of the disc is parallel to the outer plane of the circular pad. The circular pad is provided with a positioning notch and positioning holes. There are five positioning holes, evenly distributed at the center of the circular pad. However, this device cannot change the angle of the milling cutter during operation to mill inclined surfaces of different angles. Summary of the Invention

[0004] To address the problem that traditional milling machines require manual adjustment of the milling cutter angle when encountering continuous but differently angled inclined surfaces, and cannot quickly adapt to the processing of various inclined surfaces, this utility model proposes an inclined surface milling machine to solve the above problems.

[0005] A milling machine for machining inclined surfaces includes a bed with two parallel first guide rails on its upper surface, a horizontal moving component that moves linearly along the first guide rails, a rotating component above the horizontal moving component, a vertical base above the rotating component, and two parallel second guide rails on the surface of the vertical base. It also includes a power tool holder, with the second guide rails slidably connected to the power tool holder. During operation, the horizontal moving component drives the rotating component and the entire machine to move horizontally, rapidly adjusting the milling cutter position to adapt to machining various inclined surfaces.

[0006] Furthermore, a motor is installed inside the vertical base, a first fixed seat is fixedly connected to the lower surface of the top of the vertical base, and a lead screw is also included. One end of the lead screw is connected to the output end of the motor, and the other end of the lead screw is rotatably connected to the first fixed seat. A sleeve is also included, which is threadedly connected to the lead screw. A first connecting arm is also included, with both ends of the first connecting arm fixedly connected to the power tool holder and the sleeve, respectively.

[0007] Furthermore, it also includes a slider and a second connecting arm, with the two ends of the second connecting arm fixedly connected to the sleeve and the slider respectively. It also includes a positioning rod, with the slider slidably connected to the positioning rod. The lower surface of the top end and the upper surface of the bottom end of the vertical base are both fixedly connected to a second fixing seat, and the two ends of the positioning rod are installed in the second fixing seat. The positioning rod is provided to help fix and position the power tool holder, avoid misalignment caused by contact between the power tool holder and the workpiece during operation, and improve the stability of the device.

[0008] Furthermore, the inner surface of the slider is smooth, and the surface of the positioning rod is smooth.

[0009] Furthermore, the outer surface of the vertical base facing the power tool holder is provided with a through groove, the first connecting arm passes through the through groove, a limit block is provided on the surface of the first connecting arm, and a limit groove is formed on the inner surface of the through groove, the limit block moves linearly within the limit groove. The motor drives the lead screw to rotate, causing the slider to move up and down, which in turn moves the power tool holder up and down. When machining continuous and intermittent inclined surfaces, the horizontal moving component and the vertical base work together to quickly adjust the position of the milling cutter, adapting to the machining of various inclined surfaces.

[0010] The rotating component includes a support body, on the upper surface of which a bearing platform is movably connected. A vertical base is fixedly connected to the upper surface of the bearing platform. An internal gear ring is provided on the lower surface of the bearing platform. It also includes planetary gears and a drive gear. A fixed shaft is located at the center of the planetary gears and is fixedly connected to the lower surface of the bearing platform. A second bearing is provided between the fixed shaft and the planetary gears. The planetary gears mesh with the drive gear and the internal gear ring, respectively. The drive gear is connected to a gear motor. The drive gear rotates via the gear motor, which is a disc motor; other motors can be selected depending on the specific application. The drive gear drives the planetary gears to rotate, which in turn drives the internal gear ring to rotate, thereby rotating the bearing platform and other components above it. This helps adjust the milling cutter angle, allowing for rapid adjustment and adapting to the machining of various inclined surfaces.

[0011] Furthermore, a rack is provided on the upper surface of the first guide rail, and the horizontal moving component includes a horizontal moving motor. The horizontal moving motor is fixedly installed on the lower surface of the top of the horizontal moving component. Multiple sets of horizontal moving motors are arranged parallel to each other along the direction of the first guide rail. The output ends of adjacent horizontal moving motors are arranged opposite to each other. A horizontal moving gear is fixedly connected to the output end of the horizontal moving motor. The horizontal moving gear meshes with the rack. By utilizing the meshing of the gear and rack, the transmission efficiency is high, improving the response speed of the device. At the same time, the transmission is smooth, improving the stability of the device.

[0012] Furthermore, according to the claim 1, the positioning rod of the inclined milling machine is a smooth metal rod; this reduces the friction between the slider and the positioning rod, making the movement of the power tool holder more stable.

[0013] Furthermore, a first fixing seat is fixedly installed at the connection between the lead screw and the inner surface of the top of the housing, and a bearing is provided at the connection between the first fixing seat and the lead screw.

[0014] Furthermore, the outer surface of the vertical base facing the power tool holder is provided with two parallel second guide rails, the second guide rails and the power tool holder are slidably connected, and the outer surface of the vertical base facing the power tool holder is provided with a through groove, the first connecting arm extends out of the through groove and is fixedly connected to the power tool holder.

[0015] Furthermore, a limiting groove is formed on the inner surface of the through groove, and the limiting groove cooperates with a limiting block, which is located on the surface of the first connecting arm; the limiting groove is provided to further restrict the displacement of the power tool holder, prevent the power tool holder from falling out during operation, and improve the stability of the device.

[0016] Furthermore, a second guide rail is provided on the housing surface of the vertical base facing the power tool holder, and the second guide rail is slidably connected to the power tool holder; the second guide rail is provided to limit the position of the power tool holder and ensure the overall stability of the device. The power tool holder itself has a servo motor as a working power source, and the main motion and feed motion are realized by driving the servo motor. The power tool holder needs to be additionally equipped with a tool head when working.

[0017] Furthermore, a first bearing is installed between the internal gear ring and the support body, and the motor is a disc motor; using a disc motor reduces the space occupied by the motor, increases the length of the lead screw, extends the distance the power tool holder can move in the vertical direction, and improves the overall applicability of the device.

[0018] Furthermore, the second connecting arm and the slider surface are hinged, and the first connecting arm and the sleeve surface are hinged, forming an anti-jamming device to prevent jamming caused by the sleeve moving but the slider not responding in time, thereby improving the stability of the device.

[0019] Furthermore, each motor is electrically connected to a control terminal, through which staff can control and adjust each moving component.

[0020] During operation, the staff adjusts the device through the control terminal. When adjusting the horizontal moving part, the horizontal moving motor drives the horizontal moving gear to move along the rack set on the surface of the first guide rail, which in turn moves the entire device along the first guide rail, so that the device moves to the initial working position.

[0021] After reaching the initial working position, the operator adjusts the rotation angle of the milling cutter through the control terminal. The gear motor drives the drive gear to rotate, and the drive gear, through the cooperation of the planetary gear and the internal gear ring, drives the support platform and other components above the support platform to rotate by a certain angle, so that the angle of the milling cutter is the same as the angle of the inclined plane to be processed.

[0022] Finally, the staff sets the specific parameters for the vertical base and horizontal moving parts to move when the milling cutter is working, based on the dimensions of the workpiece. When the horizontal moving parts are working, the disc motor starts, causing the lead screw to rotate. The rotation of the lead screw causes the sleeve to move along the lead screw. The sleeve drives the power tool holder to move through the first connecting arm. At the same time, the sleeve is connected to the slider through the second connecting arm. The slider moves on the positioning rod. When the power tool holder moves, the limiting block set on the surface of the first connecting arm slides in the limiting groove. Meanwhile, the outer surface of the power tool holder and the second guide rail cooperate to ensure the stable operation of the power tool holder during the working process and improve the machining accuracy of the workpiece.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The horizontal moving component engages with the rack and pinion of the first guide rail, ensuring rapid and stable horizontal movement of the device, improving processing efficiency and positioning accuracy. The rotating component, through the engagement of planetary gears and internal gear rings, enables flexible rotation of the bearing platform and its components above, thereby quickly adjusting the milling cutter angle and significantly shortening the processing preparation time. The vertical base, through a motor-driven lead screw and sleeve mechanism, enables precise up-and-down movement of the power tool holder. Combined with the horizontal moving component, it can easily handle continuous and intermittent inclined surface processing needs, adapting to the processing of various inclined surfaces and further improving applicability.

[0025] 2. The positioning rod, limiting groove, and second guide rail are set to limit the sleeve, the first connecting arm, and the power tool holder housing, respectively, thereby enhancing the stability of the power tool holder, ensuring the smoothness and precision of the machining process, and improving the machining quality and consistency of the workpiece.

[0043] During operation, the operator sets the specific parameters for the vertical base 7 and the horizontal moving component 4 to move when the milling cutter is working, according to the dimensions of the workpiece. When the horizontal moving component 4 is working, the disc motor 12 starts, causing the lead screw 704 to rotate. The rotation of the lead screw 704 causes the sleeve 14 to move along the lead screw. The sleeve 14 drives the power tool holder 9 to move through the first connecting arm 13.

The two ends of the second connecting arm 15 are fixedly connected to the sleeve 14 and the slider 16, respectively. It also includes a positioning rod 705.

A horizontal moving gear 401 is fixedly connected to the output end of the horizontal moving motor 402, and the horizontal moving gear 401 meshes with the rack 201.

[0053] When adjusting the horizontal moving component 4, the horizontal moving motor 402 drives the horizontal moving gear 401 to move along the rack provided on the surface of the first guide rail 2, thereby moving the entire device along the first guide rail 2 and moving the device to the initial working position.
