Description

Technical Field

[0001] The utility model relates to the field of automated parts processing equipment, in particular to a spindle mounting seat structure of a five-axis machining center. Background Art

[0002] The five-axis machining center has five mutually perpendicular working axes, which can realize multi-directional and multi-angle processing of the workpiece. It is often used for the processing of complex curved surface parts. It can complete the processing of multiple surfaces of the workpiece in one setting, greatly improving the processing efficiency and accuracy.

[0003] In a five-axis machining center, the spindle mount is used to support and fix the spindle. Since the five-axis machining center needs to move in five directions, its spindle is usually driven by X-axis, Y-axis, and Z-axis drive mechanisms to achieve movement in the X, Y, and Z directions, while the workpiece clamping device needs to drive the workpiece to rotate or swing in the other two directions. In order to avoid mutual interference between the five-axis movements, the spindle mount usually needs to be horizontally staggered with the workpiece clamping device, which results in the five-axis machining center being larger in size, heavier in weight, more expensive, and occupies a large area, which is not conducive to the development of miniaturization. Utility Model Content

[0004] The utility model aims to overcome the defects of the above-mentioned technology and provide a spindle mounting seat structure which occupies a smaller area and is more conducive to the miniaturization of a five-axis machining center.

[0005] The spindle mounting seat structure of the five-axis machining center described in the utility model comprises a main body, a slider fixing seat vertically arranged on both sides of the main body, a slider mounting groove is arranged behind the slider fixing seat, and the slider mounting groove is used to install a slider matching with the Z-axis mounting seat slide rail. The top ends of the two slider fixing seats extend an upper extension section upward from the top of the main body, and a mounting groove for installing a driving motor is formed between the two upper extension sections at the top of the main body; the part of the main body located between the two slider fixing seats is provided with a nut fixing seat for fixing the Z-axis screw nut, and only the front side of the bottom of the main body continues to extend downward relative to the bottom of the slider fixing seat to form a lower extension portion, and a spindle mounting platform is arranged on the lower extension portion, and a limiting step for supporting the spindle is formed between the spindle mounting platform and the main body; the spindle mounting platform comprises two semicircular blocks that are relatively closed to form a spindle mounting hole, wherein the first semicircular block is connected to the bottom of the main body as a whole, and the second semicircular block is matched with the first semicircular block from the outside and is screwed on it through a connecting piece to clamp and fix the lower section of the spindle installed in the middle.

[0006] Furthermore, a portion of the front side of the body located above the limiting step is recessed inwardly to form a mounting surface matched with the surface of the main shaft.

[0007] The spindle mounting seat structure of the five-axis machining center described in the utility model has a mounting groove between the two slider fixing seats at the upper end of the body, which can be used to install the drive motor. The drive motor is hidden between the slider fixing seats, reducing the installation space required for the drive motor, making the product structure compact and conducive to the miniaturization of the product. At the same time, the front side of the lower end of the bottom of the body extends a downward extension portion at the bottom of the two slider fixing seats, and the spindle is installed on the spindle mounting table of the downward extension portion. The moving position of the spindle in the Z-axis direction is lowered to the space below the Z-axis track and the Z-axis mounting seat, and its moving distance can be used more effectively. At the same time, only the front side of the lower end of the body extends the downward extension portion, and a staggered space is formed on the rear side of the downward extension portion, which can be used to install the workpiece clamping device of the five-axis machining center. Even if the workpiece clamping device overlaps with the spindle and its moving space in the up and down and left and right directions, there will be no interference, making the product structure more compact, and the floor space and size can be relatively smaller, which is more conducive to the development of miniaturization.

[0011] like Figure 1-3As shown, a spindle mounting seat structure of a five-axis machining center includes a body 1, slider fixing seats 2 vertically arranged on both sides of the body, a slider mounting groove 21 is arranged at the rear of the slider fixing seat, a slider 31 is installed in the slider mounting groove 21, the slider 31 is matched with a Z-axis mounting seat slide rail 32, the tops of the two slider fixing seats extend an upper extension section 22 upward from the top of the body, and a mounting groove 23 for mounting a drive motor is formed between the two upper extension sections at the top of the body; the part of the body located between the two slider fixing seats 2 is also provided with a Z-axis fixing seat. The nut fixing seat 3 of the shaft screw nut, only the front part of the bottom of the body continues to extend downward relative to the bottom of the slider to form a downward extension 4, a spindle mounting platform 7 is set on the downward extension, and a limiting step 6 for supporting the spindle is formed between the spindle mounting platform and the body; the spindle mounting platform 7 also includes two semicircular blocks that are relatively closed to form a spindle mounting hole 5, wherein the first semicircular block 71 is connected to the bottom of the body as a whole, and the second semicircular block 72 is matched with the first semicircular block 71 from the outside and is screwed on it through a connecting piece to clamp and fix the bottom section of the spindle installed in the middle. The spindle mounting seat structure of the five-axis machining center is provided with an installation groove between the two slider fixing seats at the upper end of the body, which can be used to install the drive motor, and the drive motor is hidden between the slider, reducing the installation space required for the drive motor, making the product structure compact, and utilizing the miniaturization of the product. At the same time, the lower end of the body continues to extend downward from the bottom front side of the two slider fixing seats, and the spindle is installed on the spindle mounting table of the lower extension, and is carried by the spindle mounting seat to move along the Z-axis direction. The spindle moving position is lowered to the space below the Z-axis track and the Z-axis mounting seat, and its moving distance can be used more effectively. At the same time, the lower end of the body only extends the lower extension from the front side, and a staggered space is formed on the rear side of the lower extension for installing the workpiece clamping device of the five-axis machining center. Therefore, even if the installation position of the workpiece clamping device overlaps with the spindle moving position in the up and down and left and right directions, there will be no interference, which makes the product structure more compact, and the floor space and size can be relatively smaller, which is more conducive to the development of miniaturization.

[0012] The front side of the body, the part located above the limiting step 6 can be recessed inward to form a mounting surface 10 matched with the spindle surface, so that the spindle can be installed in accordance with the recessed mounting surface of the body, which is conducive to the miniaturization and smaller size of the five-axis machining center.
