Description

TECHNICAL FIELD

[0001] The utility model relates to machining center equipment field, concretely relates to a combined machining center. BACKGROUND

[0002] Traditional machining center generally adopts single spindle mode, and the same single spindle machining center can only process one workpiece at the same time. When working, after the processing of one workpiece is completed, the equipment needs to be stopped, then the workpiece is disassembled and the workpiece to be processed is installed, and then the workpiece can be processed again; this makes the equipment stop for a long time, and the equipment utilization rate and processing efficiency are low.

[0003] Further, in order to improve the shortcomings of traditional single spindle machining center, some utility model persons improve the traditional single spindle machining center, change the single spindle into double spindle, so that the machining center can process two workpieces at the same time; but the current double spindle machining center has the following shortcomings: when working, after processing two workpieces at the same time, the equipment needs to be stopped, then the workpiece is disassembled and the workpiece to be processed is installed, and then the workpiece can be processed again, so the equipment needs to be stopped for a long time, and the equipment utilization rate and processing efficiency are low. At the same time, since the operator disassembles the workpiece in the state of equipment stop, the operator must quickly disassemble the workpiece, forcing the operator to be in a tense working state, increasing the labor intensity. On the other hand, the current double spindle machining center is large in size and occupies a large space. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a combined machining center which can process two workpieces at the same time, effectively shorten the equipment downtime, improve the equipment utilization rate and processing efficiency, and reduce the labor intensity of operators.

The combined machining center has two spindle machining devices, and the spindle boxes of the two spindle machining devices can be independently controlled in the XYZ directions, so that the two spindle machining devices can simultaneously process two same or different workpieces, thereby improving the processing efficiency and versatility.

[0012] On the other hand, since the workpieces are installed on the rotatable worktable, when the spindle boxes of the two spindle machining devices are processing the workpieces on one work position, the operator can dismount the processed workpieces and install new workpieces to be processed on the other work position. When the spindle boxes of the two spindle machining devices finish processing the workpieces on the work position, the operator can drive the worktable to rotate by the rotation driving mechanism, so that the workpieces on the other work position are rotated to the machining position for processing, without waiting for the operator to dismount and install the workpieces, thereby effectively shortening the downtime of the equipment, and improving the utilization rate of the equipment and the processing efficiency.

[0033] Specific embodiment one, as shown in Figure 1 、 Figure 2 、 Figure 3 A combined machining center, comprising a frame 1, a workbench 2 rotatably arranged on the frame 1, and two spindle machining devices 3.

[0034] The spindle machining device 3 comprises an X-axis sliding seat 3.1, a Y-axis sliding seat 3.2, a spindle box 3.3, an X-axis driving mechanism, a Y-axis driving mechanism 3.7, and a Z-axis driving mechanism. The X-axis sliding seat 3.1 is slidingly connected to the frame 1 along the X-axis. The Y-axis sliding seat 3.2 is slidingly connected to the X-axis sliding seat 3.1 along the Y-axis. The spindle box 3.3 is slidingly connected to the Y-axis sliding seat 3.2 along the Z-axis. The X-axis driving mechanism drives the X-axis sliding seat 3.1 to move, and the X-axis driving mechanism is arranged on the frame 1 and / or the X-axis sliding seat 3.1. The Y-axis driving mechanism 3.7 drives the Y-axis sliding seat 3.2 to move, and the Y-axis driving mechanism 3.7 is arranged on the X-axis sliding seat 3.1 and / or the Y-axis sliding seat 3.2. The Z-axis driving mechanism drives the spindle box 3.3 to ascend and descend. The Z-axis driving mechanism is arranged on the Y-axis sliding seat 3.2 and / or the spindle box 3.3.

[0035] A rotating driving mechanism is arranged on the frame 1 to drive the workbench 2 to rotate. In this embodiment, the rotating driving mechanism comprises a rotating motor. The rotating motor can directly drive the workbench 2 to rotate, or can drive the workbench 2 to rotate through a transmission mechanism (such as a gear transmission mechanism or a synchronous belt transmission mechanism).

[0036] Since the combined machining center of the embodiment has two spindle machining devices 3, and the spindle boxes 3.3 of the two spindle machining devices 3 can realize three-axis independent control in XYZ directions, the machining of two same or different workpieces can be realized by the spindle boxes 3.3 of the two spindle machining devices 3, so as to improve the machining efficiency and versatility.

[0037] On the other hand, since the workpieces are installed on the rotatable worktable 2, when the spindle boxes 3.3 of the two spindle machining devices 3 are machining the workpieces on one work position 2.1, the operator can dismount the machined workpieces and install new workpieces to be machined on the other work position 2.1. When the spindle boxes 3.3 of the two spindle machining devices 3 complete the machining of the workpieces on the work position 2.1, the operator can drive the worktable 2 to rotate through the rotation driving mechanism, so as to rotate the workpieces on the other work position 2.1 to the machining position for machining, without waiting for the operator to dismount and install the workpieces, so as to effectively shorten the equipment downtime, thereby improving the equipment utilization and machining efficiency. On the other hand, since the operator dismounts and installs the workpieces on the other work position 2.1 during the machining of the workpieces, there is sufficient time for the dismounting and installing of the workpieces, so that the operator is in a relaxed working state, thereby reducing the labor intensity of the operator.

[0038] Specific embodiment two, as Figures 1-4 shown, a combined machining center, comprising a rack 1, a worktable 2 rotatably arranged on the rack 1, and two spindle machining devices 3.

[0039] The spindle machining device 3 comprises an X-axis slide 3.1, a Y-axis slide 3.2, a spindle box 3.3, an X-axis driving mechanism, a Y-axis driving mechanism 3.7, and a Z-axis driving mechanism. The X-axis slide 3.1 is slidably connected to the rack 1 along the X-axis.

[0040] In an example, as Figure 3 , Figure 4 shown, the X-axis slides 3.1 of the two spindle machining devices 3 are distributed side by side along the X-axis. The X-axis slides 3.1 of the two spindle machining devices 3 share a set of X-axis guides 3.4. As Figure 4 shown, the X-axis guides 3.4 in the set of X-axis guides 3.4 are two, which are arranged on the rack, and the X-axis slides 3.1 of the two spindle machining devices 3 slide along the two X-axis guides 3.4. In this way, the overall structural compactness of the combined machining center can be effectively improved, thereby effectively reducing the space occupied by the combined machining center. Of course, it should be noted that the X-axis guides 3.4 in the set of X-axis guides 3.4 can also be three or four.

[0041] In another example, the X-axis guide rails 3.4 of the X-axis slides 3.1 of the two spindle machining devices 3 are arranged independently (not shown in the figure), and the X-axis guide rails are arranged on the frame, and the X-axis slides 3.1 of the two spindle machining devices 3 are slidingly arranged on the corresponding X-axis guide rails 3.4. In this way, the two spindle machining devices 3 can be arranged flexibly.

[0042] The Y-axis slide 3.2 is slidingly connected to the X-axis slide 3.1 along the Y-axis. In this embodiment, the Y-axis slide 3.2 is slidingly connected to the X-axis slide 3.1 through the Y-axis guide rail 3.5. The spindle box 3.3 is slidingly connected to the Y-axis slide 3.2 along the Z-axis, specifically, the spindle box 3.3 is slidingly connected to the Y-axis slide 3.2 through the Z-axis guide rail 3.6. In this embodiment, each spindle machining device 3 corresponds to one spindle box 3.3. The spindles of the spindle box 3.3 are vertically distributed. It should be noted that the spindles of the spindle box 3.3 are not limited to vertical distribution, but can also be horizontally distributed. It should be noted that in actual production and manufacturing, each spindle machining device 3 can also be arranged with multiple spindle boxes 3.3.

[0043] The X-axis drive mechanism drives the X-axis slide 3.1 to move, and the X-axis drive mechanism is arranged on the frame 1 and / or the X-axis slide 3.1. The X-axis drive mechanism is an electric cylinder or a linear module, and of course the X-axis drive mechanism can also be other linear drive mechanisms on the market, for example, a screw nut linear drive mechanism.

[0044] The Y-axis drive mechanism 3.7 drives the Y-axis slide 3.2 to move, and the Y-axis drive mechanism 3.7 is arranged on the X-axis slide 3.1 and / or the Y-axis slide 3.2. The Y-axis drive mechanism 3.7 is an electric cylinder or a linear module, and of course the Y-axis drive mechanism 3.7 can also be other linear drive mechanisms on the market, for example, a screw nut linear drive mechanism.

[0045] The Z-axis drive mechanism drives the spindle box 3.3 to move up and down. The Z-axis drive mechanism is arranged on the Y-axis slide 3.2 and / or the spindle box 3.3. The Z-axis drive mechanism is an electric cylinder or a linear module, and of course the Z-axis drive mechanism can also be other linear drive mechanisms on the market, for example, a screw nut linear drive mechanism.

[0046] The rack 1 is provided with a rotating drive mechanism for driving the worktable 2 to rotate. In the embodiment, the rotating drive mechanism comprises a rotating motor. The rotating motor can directly drive the worktable 2 to rotate, or can drive the worktable 2 to rotate through a transmission mechanism (for example, a gear transmission mechanism or a synchronous belt transmission mechanism). The worktable 2 is provided with two work positions 2.1. The two work positions 2.1 are distributed on both sides of the rotating shaft of the worktable 2. Each work position 2.1 can simultaneously mount a plurality of workpieces, and the spindle boxes 3.3 of the two spindle machining devices 3 can simultaneously machine two workpieces on the same work position 2.1. Since the machining center has two spindle boxes 3.3, in the actual machining process, the number of workpieces simultaneously mounted on each work position 2.1 is generally an even number, for example, 2 or 4 or 6 workpieces are simultaneously mounted on each work position 2.1. It should be noted that the number of workpieces simultaneously mounted on each work position 2.1 can also be an odd number, for example, 1 or 3 or 5 workpieces are simultaneously mounted on each work position 2.1.

[0047] The combined machining center of the embodiment works as follows,

[0048] First, two or more workpieces are mounted on one of the work positions 2.1, and then the rotating drive mechanism drives the worktable 2 to rotate, so that the workpieces on the work position 2.1 are rotated to a machining position.

[0049] Second, the two spindle machining devices 3 drive the corresponding spindle boxes 3.3 to move to the machining position through the corresponding X-axis drive mechanism, Y-axis drive mechanism 3.7 and Z-axis drive mechanism, and simultaneously machine two workpieces (which can be two same workpieces or two different workpieces). Since the combined machining center of the embodiment has two spindle machining devices 3, and the spindle boxes 3.3 of the two spindle machining devices 3 can realize three-axis independent control in the XYZ direction, the spindle boxes 3.3 of the two spindle machining devices 3 can be used to simultaneously machine two same or different workpieces, so as to improve the machining efficiency and versatility. For example, when the spindle boxes 3.3 of the two spindle machining devices 3 machine two same workpieces, the spindle box 3.3 of one of the spindle machining devices 3 realizes milling of the workpiece, and the spindle box 3.3 of the other spindle machining device 3 realizes drilling of the workpiece; or the spindle boxes 3.3 of the two spindle machining devices 3 simultaneously realize milling of the workpiece.

[0050] At the same time, the operator can mount workpieces to be machined on another work position 2.1. When the workpieces on one of the work positions 2.1 are machined, the rotating drive mechanism can drive the worktable 2 to rotate, so that the workpieces on another work position 2.1 are rotated to a machining position.

[0051] Thirdly, return to the second step, and so on. Thus, the combined machining center of the embodiment can effectively shorten the equipment downtime, thereby improving the equipment utilization and processing efficiency. On the other hand, since the workers are in the process of workpiece machining, the workpiece disassembly and installation on the other work position 2.1 is carried out, so there is enough time to disassemble and install the workpiece, so that the workers are in a relaxed working state, thereby reducing the labor intensity of the workers.

[0052] Specifically, as shown in Figures 1-4 The base 1.1 and the gantry 1.2 are integrally formed; or the base and the gantry 1.2 are separately manufactured, and then the base and the gantry 1.2 are connected by bolts or welding. The gantry 1.2 includes a top cross beam 1.3. The length direction of the top cross beam 1.3 is parallel to the sliding direction of the X-axis slide 3.1, that is, the length direction of the top cross beam 1.3 is parallel to the X-axis direction. The X-axis slides 3.1 of the two spindle machining devices 3 are slidably connected to the top cross beam 1.3 along the X-axis direction. In the embodiment, the X-axis guide rails 3.4 are installed on the upper surface of the top cross beam 1.3, and the X-axis guide rails 3.4 are parallel to the length direction of the top cross beam 1.3. The X-axis slides 3.1 slide along the X-axis guide rails 3.4 on the top cross beam 1.3. The rack structure of the embodiment can not only ensure the structural stability of the rack 1 itself, but also effectively improve the compactness of the overall structure of the combined machining center, thereby effectively reducing the space occupied by the combined machining center.

[0053] In one embodiment of the embodiment, as shown in Figure 4As shown, the X-axis guide rails 3.4 are two, and the two X-axis guide rails 3.4 are distributed along the Y-axis direction. One of the X-axis guide rails 3.4 is defined as a high-level guide rail 3.41, and the other is defined as a low-level guide rail 3.42. The position where the high-level guide rail 3.41 is located is higher than the low-level guide rail 3.42. The bottom of the X-axis sliding seat 3.1 is provided with a bottom notch 3.8 corresponding to the high-level guide rail 3.41, and the high-level guide rail 3.41 is located in the bottom notch 3.8, and the bottom notch 3.8 penetrates the X-axis sliding seat 3.1 along the X-axis guide rail 3.4. In this embodiment, the high and low arrangement of the two X-axis guide rails 3.4 is beneficial to improve the sliding stability of the X-axis sliding seat 3.1. On the other hand, due to the high and low arrangement of the two X-axis guide rails 3.4, the bottom of the X-axis sliding seat 3.1 can be arranged with a bottom notch 3.8 corresponding to the high-level guide rail 3.41 to accommodate the high-level guide rail 3.41, so as to effectively reduce the weight of the X-axis sliding seat 3.1. The lighter the X-axis sliding seat 3.1, the more conducive to improving the moving precision of the X-axis driving mechanism driving the X-axis sliding seat 3.1.

[0054] In another embodiment of the present embodiment, the X-axis guide rails 3.4 are two or more than two, and each X-axis guide rail 3.4 is sequentially distributed along the Y-axis direction. Each X-axis guide rail 3.4 is located at the same height (not shown in the figure).

[0055] In the present embodiment, as shown, Figures 1-4 the workbench 2 is rotationally arranged on the base, and the rotary driving mechanism is arranged on the base.

[0056] Further, as shown, Figure 2 the X-axis sliding seat 3.1 is provided with a longitudinal accommodating groove with an opening facing the Y-axis sliding seat 3.2. In the present embodiment, the Y-axis sliding seat 3.2 is located above the X-axis sliding seat 3.1, and the opening of the longitudinal accommodating groove faces upward. The longitudinal accommodating groove extends along the sliding direction of the Y-axis sliding seat 3.2, and at least one end of the longitudinal accommodating groove is open. The Y-axis driving mechanism 3.7 is arranged in the corresponding longitudinal accommodating groove. In this way, on the one hand, the Y-axis driving mechanism 3.7 can be accommodated in the longitudinal accommodating groove, thereby further improving the compactness of the structure and reducing the space occupied by the combined machining center. On the other hand, the longitudinal accommodating groove can also effectively reduce the weight of the X-axis sliding seat 3.1. The lighter the X-axis sliding seat 3.1, the more conducive to improving the moving precision of the X-axis driving mechanism driving the X-axis sliding seat 3.1.

[0057] Further, as shown, Figure 4As shown, the side of the Y-axis slide 3.2 facing the spindle box 3.3 is provided with a vertical accommodating groove 3.9. The vertical accommodating groove 3.9 penetrates the upper and lower ends of the Y-axis slide 3.2. The Z-axis driving mechanism is arranged in the corresponding vertical accommodating groove 3.9. In this way, on the one hand, the Z-axis driving mechanism can be accommodated by the vertical accommodating groove 3.9, thereby further improving the compactness of the structure and reducing the space occupied by the combined machining center; on the other hand, the vertical accommodating groove 3.9 can also effectively reduce the weight of the Y-axis slide 3.2, and the lighter the weight of the Y-axis slide 3.2, the more conducive to improving the moving precision of the Y-axis driving mechanism 3.7 driving the Y-axis slide 3.2. In addition, part of the heat generated during the high-speed operation of the spindle box 3.3 can be discharged through the vertical accommodating groove 3.9, which is conducive to the heat dissipation of the spindle box 3.3.

[0058] Further, the combined machining center also includes a tool magazine 4. Specifically,

[0059] In an embodiment, as shown in the drawings, Figures 1-3 The combined machining center has two tool magazines 4. The two tool magazines 4 are distributed on both sides of the rack 1 along the sliding direction of the X-axis slide 3.1, and the spindle boxes 3.3 of the two spindle machining devices 3 are located between the two tool magazines 4. The spindle box 3.3 corresponds to one of the tool magazines 4. The tool on the spindle box 3.3 is automatically changed by the corresponding tool magazine 4. In this way, the automatic tool changing of the spindle box 3.3 can be realized through the tool magazine 4 to perform boring, milling, drilling, tapping and other different machining processes.

[0060] In another embodiment, the combined machining center has one tool magazine 4, which is located between the spindle boxes 3.3 of the two spindle machining devices 3 (not shown in the drawings). The tool magazine 4 can automatically change the tools for the two spindle boxes 3.3, that is, the spindle boxes 3.3 of the two spindle machining devices 3 share one tool magazine 4. In this way, the automatic tool changing of the spindle box 3.3 can be realized through the tool magazine 4 to perform boring, milling, drilling, tapping and other different machining processes.

[0061] Further, as shown in the drawings, Figures 1-4 The workbench 2 is provided with a partition 2.2. The partition 2.2 separates the two workstations 2.1 on the workbench 2. In this way, when the spindle boxes 3.3 of the two spindle machining devices 3 are machining a workpiece on one of the workstations 2.1, the partition 2.2 can block the high-speed rotating tool and the splashing debris generated during machining, avoiding the safety hazards of accidentally touching the high-speed rotating tool and being scratched by the splashing debris when the operator is operating on the other workstation 2.1, thereby improving the safety of the operator when disassembling and installing the workpiece on the other workstation 2.1.

[0062] Further, as shown in the drawings, Figure 1 , Figure 2As shown in the drawings, the top of the partition plate 2.2 is provided with an upper baffle 2.3, a part of the upper baffle 2.3 extends to one of the working positions 2.1 to form a working position 2.1 blocking part, and another part of the upper baffle 2.3 extends to another working position 2.1 to form a working position 2.1 blocking part. In this way, on the one hand, the installation of the partition plate 2.2 can be facilitated by the installation plate; on the other hand, the blocking effect of the splashed debris can be further improved by the blocking part on the top of the partition plate 2.2, thereby further improving the safety of the worker in another working position 2.1 when performing the disassembly and installation operation of the workpiece.

[0063] The bottom of the partition plate 2.2 is provided with an installation plate, and the installation plate is connected with the workbench 2 by bolts or welding or riveting. In this way, the installation of the partition plate 2.2 can be facilitated by the installation plate.

[0064] Further, as shown in the drawings, Figure 1 , Figure 2 The upper surface of the workbench 2 is provided with a workpiece mounting groove 2.4 or a workpiece mounting hole, and the workpiece mounting groove 2.4 is a T-shaped groove or a dovetail groove. In this embodiment, the upper surface of the workbench 2 where each working position 2.1 is located is provided with a workpiece mounting groove 2.4 or a workpiece mounting hole.

[0065] In one example, as shown in the drawings, Figure 1 , Figure 2 The upper surface of the workbench 2 where each working position 2.1 is located is provided with a workpiece mounting groove 2.4, and the workpiece mounting groove 2.4 is a T-shaped groove or a dovetail groove.
