Description

Technical Field

[0001] The present invention relates to the field of numerically controlled machine tools, in particular to a rotary tool magazine for a horizontal machining center and the horizontal machining center. Background Art

[0002] A horizontal machining center is a highly efficient, precision CNC machine tool with a spindle axis parallel to the worktable, making it particularly suitable for machining large, heavy, or complex workpieces. Horizontal machining centers have the ability to automatically change machining tools. By installing tools of varying applications in the tool magazine and using an automatic tool changer to change the tool on the spindle, multiple processes can be completed in a single setup, reducing the number of workpiece movements and improving machining accuracy.

[0003] Currently, most tool magazines used in horizontal machining centers on the market are top-mounted disc tool magazines or side-mounted chain tool magazines. For example, Chinese invention patent application CN108436557A discloses a horizontal machining center and a disc tool magazine. The disc tool magazine is configured by placing a tool magazine bracket on a machine tool and arranging a cutter disc, a sliding mechanism, and a rotating mechanism on the magazine bracket. The sliding mechanism drives the cutter disc to extend and retract, and the rotating mechanism drives the cutter disc to rotate, thereby achieving tool change efficiency. However, the disc tool magazine is limited in the number of tools it can hold. When a large number of tools are required, the disc tool magazine is larger in size, requiring a large installation space. This occupies the space for the spindle to move up and down, resulting in low space utilization for the horizontal machining center. For example, Chinese utility model patent CN217167623U discloses a chain-type tool magazine for a horizontal machining center. This tool magazine saves horizontal space inside the machine tool by vertically positioning the tool magazine on the side of the spindle. However, due to the long chain structure and slow chain speed of the chain-type tool magazine, tool changes take a long time when the distance between the tool to be installed and the tool to be removed is large, seriously affecting machining efficiency. Furthermore, the tool will sag slightly under its own gravity. Since the weight of different tools varies, the degree of sag will vary, meaning that the center axis of the tool will shift to varying degrees, causing the center axis of the tool to misalign with the center axis of the spindle during tool changes. This can lead to problems such as tool changes not being smooth, tool jamming, and wear on the spindle mounting hole.

[0004] Therefore, it is necessary to provide a technical solution to solve the above problems. Summary of the Invention

[0008] Furthermore, the number of the non-working surface in the installation body is one.

[0009] Furthermore, a tool clamp driver is provided on the mounting body corresponding to each tool clamp, and the tool clamp driver is used to drive the corresponding tool clamp to open or close, and the tool clamp driver is control-connected to the control mechanism.

[0010] Furthermore, the mounting body is in the shape of a prism.

[0030] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0031] Example 1

[0032] like Figures 1 to 5As shown, this embodiment provides a rotary tool magazine for a horizontal machining center, the rotary tool magazine includes a control mechanism and a tool magazine mechanism connected to the control mechanism, the tool magazine mechanism includes a mounting body 1 and a rotary driver for driving the mounting body to rotate, the rotary driver being connected to the control mechanism; a plurality of tools 2 are mounted on the mounting body 1, the central axis of each tool 2 being perpendicular to the central axis (i.e., the rotation axis) of the mounting body 1; tool information of each tool 2 is stored in the control mechanism, the tool information including a tool number and a tool droop compensation angle value; during the tool change process, when the tool to be mounted on the mounting body 1 needs to be inserted into the spindle 85 of the horizontal machining center, the control mechanism controls the rotary driver to compensate the rotation angle of the mounting body 1 according to the tool droop compensation angle value of the tool to be mounted, so that when the spindle 85 is opposite to the tool to be mounted, the central axis of the tool to be mounted coincides with the central axis of the spindle 85. Specifically, the tool information also includes a tool number.

[0033] During actual use, the tool 2 on the mounting body 1 will sag slightly under the action of its own gravity. Since the tools 2 used for processing parts in the tool magazine mechanism are of various types, the weight and length of different tools 2 will be different. Therefore, the degree of sagging of different tools will also be different. For tools that are heavier or longer, the sagging phenomenon is more obvious; when the mounting body 1 is rotated to the position where the tool to be installed is relative to the spindle 85, the sagging phenomenon will cause the central axis of the tool to be installed to be non-parallel with the central axis of the spindle 85, which will cause problems such as unsmooth tool changing, and even tool jamming and wear of the spindle mounting hole.

[0034] In order to solve the above technical problems, in this embodiment, the tool droop compensation angle value of each tool 2 is pre-stored in the control mechanism. During the tool changing process, the control mechanism controls the rotary driver to compensate the rotation angle of the installation body 1 according to the tool droop compensation angle value corresponding to the tool to be installed, so that when the spindle 85 is opposite to the tool to be installed, the central axis of the tool to be installed coincides with the central axis of the spindle 85, avoiding problems such as uneven tool changing, tool jamming, and wear of the spindle mounting hole.

[0035] Furthermore, if Figure 1-5As shown, at least one row of tool holder groups is installed on the outer surface of the mounting body 1, and each row of the tool holder groups includes a plurality of tool holders 3 arranged at intervals along the direction of the central axis of the mounting body 1, and the tool 2 is installed in the tool holder 3; the outer surface of the mounting body 1 is provided with a plurality of side surfaces, each of which is arranged parallel to the central axis of the mounting body 1, at least one of the side surfaces in the mounting body 1 is a non-working surface 11, and the remaining side surfaces are working surfaces 12, the number of rows of the tool holder groups is the same as the number of the working surfaces 12, and the tool 2 clamped by each row of tool holder groups is located on the outside of the working surface 12 corresponding to the tool holder group, and no tool 2 is arranged on the outside of each non-working surface 11; when the tool 2 on the spindle 85 needs to process the workpiece on the worktable of the horizontal machining center, the rotary drive drives the mounting body 1 to rotate to the machining state, at which time one of the non-working surfaces 11 of the mounting body 1 faces the worktable of the horizontal machining center. Specifically, the shape of the mounting body 1 is a prism, and specifically, the prism can be a triangular prism (such as Figure 1-2 As shown), quadrangular prism (as Figure 3-4 ), a pentagonal prism, etc.; of course, the mounting body 1 may also have other shapes, as long as a plurality of side surfaces parallel to the central axis of the mounting body 1 are formed on the outer surface of the mounting body 1. Since the greater the number of working surfaces 12, the greater the number of tools 2 that can be installed, the number of non-working surfaces 11 in the mounting body 1 is preferably one, thereby effectively increasing the number of tools that can be loaded into the rotary tool magazine.

[0036] In actual use, the installation position of each tool 2 in the installation body 1 is fixed; when it is necessary to change the tool on the spindle 85 of the horizontal machining center, the control mechanism controls the rotary driver to drive the installation body 1 to rotate to the position where the jaws of the tool clamp group in the row where the tool clamp is located are relative to the spindle 85 according to the position of the tool clamp 1 on the installation body 1 for installing the tool to be removed from the spindle 85. At the same time, the horizontal machining center also drives the spindle 85 to move according to the position of the tool clamp 1. Since the movement speed of the spindle 85 can be as high as 120 meters / minute, it can quickly move to the position corresponding to the tool clamp 1 and insert the tool to be removed into the tool clamp 1 corresponding to it. The tool clamp 1 clamps the tool to be removed, and then the spindle 85 continues to move, so that the tool to be removed is separated from the spindle 85, completing the tool return step. ; Then the control mechanism determines the angle value by which the installation body 1 needs to rotate according to the position of the tool to be removed in the installation body 1, the position of the tool to be installed in the installation body 1, and the tool droop compensation angle value of the tool to be installed. The control mechanism controls the rotary driver to drive the installation body 1 to rotate according to the angle value by which the installation body 1 needs to rotate. At the same time, the horizontal machining center drives the spindle 85 to move according to the position of the tool to be installed. The spindle 85 moves quickly to the position corresponding to the tool to be installed. At this time, the center axis of the tool to be installed coincides with the center axis of the spindle 85, and the tool to be installed is inserted into the mounting hole of the spindle 85. The tool holder 2 for clamping the tool to be installed releases its clamping of the tool to be installed at this time, and then the spindle 85 continues to move, so that the tool to be installed is separated from the tool holder 2, completing the tool removal step. After the tool change is completed, when the workpiece on the workbench 83 needs to be processed, the control mechanism controls the rotary driver to drive the mounting body 1 to rotate to the processing state. At this time, one of the non-working surfaces 11 of the mounting body 1 faces the workbench 83 of the horizontal machining center. Since no tool 2 is set on the outside of the non-working surface 11, the non-working surface 11 faces the workbench 83, that is, the processing area of ​​the horizontal machining center (such as Figure 8 ), and the case where the working surface 12 faces the working table 83 (as shown Figure 7 Compared with the horizontal machining center (shown in FIG), the space for the spindle 85 to move along the Y-axis direction (i.e., the up and down direction) can be effectively increased. That is, the situation where the non-working surface 11 faces the workbench 83 can effectively avoid the maximum stroke of the spindle 85 along the Y-axis direction and avoid interference with the Y-axis movement of the spindle 85, thereby maximizing the internal space of the horizontal machining center and maximizing the utilization of the motion stroke, so that the horizontal machining center can process larger workpieces, and increases the size range of workpieces that can be processed by the horizontal machining center.

[0037] The rotary tool magazine in this embodiment is provided with multiple side surfaces on the outer surface of the mounting body 1, and by setting one side surface as a non-working surface 11 and the other side surfaces as working surfaces 12, a row of tools 2 can be set on the outside of each working surface 12, while no tools 2 are set on the outside of the non-working surface 11. Such a setting can not only ensure the tool loading capacity of the rotary tool magazine, but more importantly, it can also realize that when the horizontal machining center needs to process the workpiece, the mounting body 1 can be rotated to a state where the non-working surface 11 faces the machining area of ​​the horizontal machining center, which can effectively increase the space for the spindle 85 to move along the Y-axis direction, maximize the internal space of the horizontal machining center and maximize the utilization of the motion stroke, and also increase the size range of workpieces that can be processed by the horizontal machining center. Furthermore, the installation position of each tool 2 in the rotary tool magazine in this embodiment is fixed in the mounting body 1, and the spindle quickly moves to the corresponding position point to return and remove the tool, which greatly shortens the time of the tool return and removal process and improves the tool change efficiency.

[0038] Furthermore, the rotary driver is a direct-drive motor. In this embodiment, the direct-drive motor is directly connected to the mounting body 1, eliminating the need for gears, drive belts, chains, and other transmission components. This not only makes the rotary tool magazine more compact and occupies less space, but also improves transmission efficiency and ensures precise control of the rotation angle of the mounting body 1, ensuring smooth tool return and removal.

[0039] Furthermore, if Figure 4-5 As shown, each tool holder 3 on the mounting body 1 is provided with a tool holder actuator 4. The tool holder actuator 4 is used to drive the corresponding tool holder 3 to open or close. The tool holder actuator 4 is controllably connected to the control mechanism. Specifically, the tool holder actuator 4 is located on the side of the corresponding tool holder 3 away from the tool holder 2 it holds. When the tool holder actuator 4 extends toward the corresponding tool holder 3, the jaws on the tool holder 3 that hold the tool 2 open under the action of the tool holder actuator 4. When the tool holder actuator 4 retracts away from the corresponding tool holder 3, the jaws are automatically closed under the action of the elastic mechanism. In this embodiment, the control mechanism controls the forward extension or backward retraction of each tool holder actuator 4 to precisely control the opening or closing of each tool holder 3.

[0040] Furthermore, the rotary tool magazine further includes a mounting base 5 and two support bases 6. The two ends of the mounting body 1 are rotatably mounted in the two support bases 6, and the two support bases 6 are arranged on the mounting base 5. Specifically, the two ends of the mounting body 1 are rotatably mounted in the two support bases 6 via bearings.

[0041] Furthermore, if Figure 6As shown, the rotary tool magazine further includes a Z-axis guide mechanism 7 and a Z-axis drive mechanism. The two support seats 6 are arranged on the mounting seat 5 through the Z-axis guide mechanism 7. The Z-axis drive mechanism is used to drive the two support seats 6 to move synchronously along the Z-axis guide mechanism 7. Specifically, the Z-axis guide mechanism 7 is a guide rail, and the guide rail is arranged on both sides of the mounting seat 5. The Z-axis drive mechanism can be an electric push rod, a motor ball screw mechanism, etc. In this embodiment, by adding movement in the Z-axis direction to the rotary tool magazine, the rotary tool magazine can also be applied to a horizontal machining center in which the spindle 85 can only move in the X-axis and Y-axis directions and cannot move in the Z-axis direction. The movement of the rotary tool magazine in the Z-axis direction can send the mounting body 1 to the tool changing position of the spindle 85 for tool changing, which helps to improve the scope of application of the rotary tool magazine in this embodiment.

[0042] Example 2

[0043] This embodiment provides a horizontal machining center, which includes the rotary tool magazine for the horizontal machining center described in any implementation manner in Example 1.

[0044] Furthermore, if Figure 7-8As shown, the horizontal machining center further includes a frame 81, a column 82, a worktable 83, and a spindle box 84. The column 82 and the worktable 83 are both arranged on the frame 81. The spindle box 84 is slidably mounted on the column 82. The spindle 85 is mounted on the spindle box 84. The rotary tool magazine is mounted on the frame 81 and is located above the worktable 83. Specifically, the rotary tool magazine is strip-shaped and arranged on the frame 81 along the X-axis. The rotary tool magazine has a large tool loading capacity and a small overall volume. In the horizontal machining center, it does not occupy the processing space of the workpiece or the movement stroke of the spindle. The rotary tool magazine is installed above the worktable 83 but not directly above the worktable 83. Its central axis along the Y-axis direction is offset relative to the central axis of the worktable 83 along the Y-axis direction toward the direction of the spindle 85. This arrangement allows the rotary tool magazine to effectively avoid the space directly above the worktable 83, thereby helping to obtain space for hoisting workpieces in the horizontal machining center. In addition, a non-working surface 11 is provided in the rotary tool. When the horizontal machining center needs to process the workpiece on the workbench 83, the mounting body 1 is rotated to a state where the non-working surface 11 faces the machining area of ​​the horizontal machining center, thereby effectively increasing the space for the spindle to move along the Y-axis direction, maximizing the internal space of the horizontal machining center and maximizing the utilization of the motion stroke, and also increasing the size range of the workpiece that can be processed by the horizontal machining center. In addition, the movement speed of the spindle 85 in the horizontal machining center can be as high as 120 meters per minute. By quickly moving the spindle to the corresponding position point to return and remove the tool, the time of the tool return and removal process is greatly shortened, the tool change efficiency is improved, and thus the overall machining efficiency of the horizontal machining center is effectively improved. As for the drive mechanism of the column 82, the drive mechanism of the spindle box 84 and the drive mechanism of the workbench 83, they are all consistent with the horizontal machining center in the prior art and will not be repeated here. The horizontal machining center is provided with a control system for controlling the drive mechanism of the column, the drive mechanism of the spindle box, the drive mechanism of the workbench and the rotary tool magazine.

[0045] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
