Description

Technical Field

[0001] This utility model belongs to the technical field of horizontal machining centers, and in particular a five-axis horizontal machining center. Background Technology

[0002] In existing five-axis horizontal machining centers, workpiece fixation typically relies on mechanical fixtures or hydraulic systems. While these methods achieve a certain degree of positioning and locking, mechanical fixtures require frequent adjustments during multi-angle switching, making operation complex. Hydraulic systems, although offering faster response times, are prone to reduced locking accuracy due to oil circuit leaks or unstable pressure, thus affecting workpiece machining quality. This is especially true during multi-axis simultaneous machining of complex parts; unstable fixation can lead to minute workpiece displacements, accumulating errors and reducing the dimensional accuracy and surface quality of the finished product. Therefore, there is an urgent need for a five-axis horizontal machining center with a simple fixation method, high positioning accuracy, and rapid response to improve machining stability and efficiency.

[0015] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0016] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0017] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0018] Please see Figures 1 to 3 The structure of the device body is that of a five-axis horizontal machining center, including a base 1, a drive assembly, a column 7, a spindle box 10, an angle head 11, a turntable 3, electromagnets 34, a bracket 13, and a tool magazine 12. The base 1 is integrally cast and aged to improve overall rigidity and stability. The upper part of the base 1 is equipped with a drive box 2, which houses a servo motor and a reduction mechanism. The turntable 3 is mounted on the upper part of the drive box 2. The turntable 3 is composed of a high-strength steel disc body 31. Several limiting grooves 32 are formed on the upper part of the disc body 31 for initial positioning with the workpiece fixture. The lower part of the disc body 31 is equipped with an annular groove 33, in which multiple high-performance electromagnets 34 are evenly distributed circumferentially. A connecting sleeve 35 is provided at the center of the groove 33. During machining, the electromagnets 34 generate a strong attraction force after being energized, which cooperates with the workpiece fixture to form multi-point electromagnetic locking, which can fix the workpiece instantly. Compared with mechanical or hydraulic clamping, this is faster and more accurate, and avoids the instability caused by oil leakage.

[0019] The drive assembly includes an X-axis guide rail 4 and a first slide 5, which moves along the X-direction under the drive of the X-axis guide rail 4. A Z-axis guide rail 6 is located on the upper part of the first slide 5, perpendicular to the X-axis guide rail 4. A column 7 is mounted on the guide rail, and a Y-axis guide rail 8 is located on the side of the column 7. A second slide 9 is mounted on the Y-axis guide rail 8. The X-axis guide rail 4, Z-axis guide rail 6, and Y-axis guide rail 8 are all electrically driven. A spindle box 10 is located on the side of the second slide 9. The spindle box 10 contains a high-speed electric spindle and is equipped with a cooling and lubrication system to ensure stable operation over long periods. An angle head 11 is mounted on one side of the spindle box 10. The angle head 11 can be adjusted under the drive of the high-speed electric spindle to achieve multi-angle cutting of complex curved surfaces.

[0020] A bracket 13 is mounted on the side of the base 1, and a tool magazine 12 is mounted on top of the bracket 13, which can accommodate tools of various sizes. During tool changing, the robotic arm quickly retrieves a tool from the tool magazine 12 and installs it onto the spindle under the control of the CNC program, realizing automated tool switching and shortening the machining preparation time.

[0021] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0022] Working principle During operation, the device first places the workpiece in the corresponding position of the limiting groove 32 on the turntable 3. Once the electromagnet 34 is energized, it immediately performs high-precision locking, ensuring the workpiece does not shift during subsequent high-speed cutting. Subsequently, the drive assembly controls the spindle to move precisely along the X, Y, and Z axes, while the angle head 11 adjusts the angle, completing five-axis linkage machining. During machining, the electromagnet 34 maintains a stable magnetic force, avoiding precision loss caused by vibration-induced loosening of the mechanical clamp. After machining, the electromagnet 34 is de-energized, allowing the workpiece to be quickly removed, significantly improving work efficiency.
