Description

Technical Field

[0001] This utility model relates to the field of machining center technology, specifically to a synchronous moving multi-spindle vertical machining center. Background Technology

[0002] Traditional machining centers typically use a single spindle, meaning that only one workpiece can be processed at a time. In practice, after one workpiece is finished, the machine needs to be stopped for disassembly and installation of the next workpiece before machining can resume. This results in long downtime for clamping and reassembly, leading to low equipment utilization and processing efficiency.

[0003] Furthermore, to address the shortcomings of traditional single-spindle machining centers, some inventors have improved upon them by converting them into dual-spindle machining centers, enabling the center to process two workpieces simultaneously. However, in current dual-spindle machining centers, the drive systems of the two spindles are independent, with each spindle corresponding to its own independent drive system. This independent drive system drives the corresponding spindle to move along the X, Y, and Z axes, significantly increasing the overall size of the equipment and its space requirements, as well as manufacturing costs. On the other hand, during operation, after processing two workpieces simultaneously, the dual-spindle machining center still requires machine shutdown for disassembly and installation of the workpieces to be processed before it can resume processing. This results in long downtime for clamping and reassembly, leading to low equipment utilization and processing efficiency. Moreover, since operators must disassemble and assemble workpieces while the equipment is stopped, this requires rapid work, forcing operators into a tense working state and increasing labor intensity. Utility Model Content

[0004] The purpose of this invention is to provide a synchronous moving multi-spindle vertical machining center that can not only process two or more workpieces simultaneously to improve processing efficiency, but also has a compact structure that can effectively reduce the manufacturing cost and space occupied by the machining center.

[0005] Another objective of this invention is to provide a synchronous moving multi-spindle vertical machining center that can effectively shorten equipment downtime, thereby improving equipment utilization and processing efficiency, and reducing the labor intensity of operators.

[0006] The technical solution of this utility model is:

[0007] A synchronous moving multi-spindle vertical machining center, comprising:

[0008] frame;

[0009] The sliding base is slidably connected to the frame in a horizontal direction, and the base moving mechanism drives the sliding base to move.

[0010] The spindle slide is slidably connected to the sliding base in the horizontal direction. The sliding directions of the sliding base and the spindle slide are perpendicular. The slide moving mechanism drives the spindle slide to move.

[0011] The spindle box is slidably connected to the spindle slide in the vertical direction. The spindle box is equipped with at least two spindle heads. The lifting and moving mechanism drives the spindle box to lift and lower.

[0012] A rotary worktable mounted on the frame and a drive motor for rotating the worktable are included. This solution provides a synchronously moving multi-spindle vertical machining center with a spindle head having at least two spindle heads. Each spindle head can be equipped with a cutting tool to machine the workpiece. Therefore, two or more workpieces can be machined simultaneously through the spindle heads on the spindle head, improving machining efficiency. Furthermore, since the spindle heads share a base moving mechanism, a slide moving mechanism, and a lifting moving mechanism, the overall structural compactness of the machining center is effectively improved, reducing the space occupied and lowering manufacturing costs.

[0013] On the other hand, since the workpieces are mounted on a rotatable rotary table, while the workpieces at one of the spindle heads on the spindle box are being processed, the operator can disassemble the completed workpieces and install new workpieces at another workpiece position. After the spindle heads on the spindle box have finished processing the workpieces at one workpiece position, the operator can use the rotary drive mechanism to rotate the worktable and move the workpieces at another workpiece position to the machining position for processing, without waiting for the operator to disassemble or install workpieces. This effectively shortens equipment downtime, thereby improving equipment utilization and processing efficiency. Furthermore, because the operator disassembles and installs workpieces at another workpiece position while the workpiece is being processed, there is ample time for disassembly and installation, allowing the operator to work in a relaxed state and reducing labor intensity.

[0014] Preferably, the spindle heads on the spindle box are sequentially distributed along the sliding direction of the sliding base. Each spindle head includes a spindle rotatably mounted on the spindle box and a spindle motor that drives the spindle to rotate. In this way, each spindle head on the spindle box can simultaneously process two or more workpieces sequentially distributed along the sliding direction of the sliding base.

[0015] Preferably, the spindle heads on the spindle box are arranged sequentially along the sliding direction of the spindle slide. Each spindle head includes a spindle rotatably mounted on the spindle box and a spindle motor that drives the spindle to rotate. In this way, each spindle head on the spindle box can simultaneously process two or more workpieces arranged sequentially along the sliding direction of the spindle slide.

[0016] Preferably, the rotary worktable has two working positions, which are located on both sides of the rotary axis of the rotary worktable. Each working position can install multiple workpieces at the same time.

[0017] Preferably, a partition is provided on the upper surface of the rotary table, which separates the two working positions on the table. In this way, during the machining process of the workpiece at one working position by the spindle heads on the spindle box, the partition can block the flying debris generated during machining, avoiding safety hazards such as accidental contact with the high-speed rotating tool or being cut by flying debris when the operator is working at the other working position. This improves the safety of the operator when performing workpiece disassembly and installation operations at the other working position.

[0018] Preferably, the partition has an upper baffle at the top and a mounting plate at the bottom. The mounting plate is bolted or welded to the upper surface of the rotary table. A portion of the upper baffle extends towards one working position to form a working position blocking part, and another portion extends towards another working position to form a working position blocking part. The upper surface of each working position of the rotary table has a workpiece mounting groove or a workpiece mounting hole. The workpiece mounting groove is a T-slot or a dovetail groove. This further enhances the blocking effect on flying debris by using the working position blocking part at the top of the partition, preventing debris from flying upwards along the partition, thereby further improving the safety of the operator when performing workpiece disassembly and installation operations at another working position. On the other hand, in actual use, the workpiece can be mounted on a tooling; then, the tooling is installed into the workpiece mounting groove or workpiece mounting hole, thus achieving workpiece installation.

[0019] Preferably, a vertical receiving groove is provided on the side of the spindle slide facing the spindle box, extending through both the upper and lower ends of the spindle slide. The lifting and moving mechanism is arranged within the vertical receiving groove. This design allows the lifting and moving mechanism to be accommodated within the vertical receiving groove, further improving structural compactness and reducing the space occupied by the machining center. Furthermore, the vertical receiving groove effectively reduces the weight of the spindle slide, and a lighter spindle slide improves the accuracy of the movement of the slide mechanism. Additionally, some of the heat generated during the high-speed operation of the spindle box can be dissipated through the vertical receiving groove, facilitating heat dissipation for the spindle box.

[0020] Preferably, the frame includes a base and a gantry frame mounted on the base. The gantry frame includes a top beam with two X-axis guide rails. One X-axis guide rail is defined as a high-position guide rail, and the other X-axis guide rail is defined as a low-position guide rail. The height of the high-position guide rail is higher than that of the low-position guide rail. The sliding base slides along the two X-axis guide rails. A bottom notch is provided on the bottom of the sliding base at a position corresponding to the high-position guide rail. The high-position guide rail is located in the bottom notch, and the bottom notch penetrates the sliding base along the X-axis guide rail direction.

[0021] The main spindle slide is slidably connected to the sliding base along the Y-axis. One of the sliding base and the main spindle slide has a longitudinal receiving groove extending along the Y-axis, and the slide movement mechanism is arranged within the longitudinal receiving groove. This design ensures the structural stability of the frame itself. Furthermore, the use of two X-axis guide rails arranged at different heights not only improves the sliding stability of the sliding base but also allows for a bottom notch on the sliding base corresponding to the higher guide rail, accommodating it. This reduces the weight of the sliding base, and a lighter sliding base improves the accuracy of the base movement mechanism in driving the sliding base.

[0022] In addition, one of the sliding base and the spindle slide is provided with a longitudinal receiving groove extending along the Y-axis. In this way, not only can the slide movement mechanism be arranged through the longitudinal receiving groove, thereby further improving the structural compactness and reducing the space occupied by the machining center, but the longitudinal receiving groove can also reduce the weight of the sliding base or the spindle slide. The lighter the weight of the sliding base or the spindle slide, the more beneficial it is to improve the movement accuracy of the sliding base or the spindle slide.

[0023] As a preferred embodiment, the frame includes a base, two left and right side uprights mounted on the base, and a connecting frame connecting the two side uprights. The top of each of the two side uprights is provided with a Y-axis guide rail, and the sliding base is supported on the Y-axis guide rail and slides along the Y-axis guide rail.

[0024] An X-axis guide rail is provided on the sliding base, and the main spindle slide slides along the X-axis guide rail. The frame structure of this design can ensure the structural stability of the frame structure itself.

[0025] The beneficial effects of this utility model are:

[0026] Firstly, it can not only process two or more workpieces simultaneously to improve processing efficiency, but also has a compact structure that can effectively reduce the manufacturing cost and space occupied by the machining center.

[0027] Secondly, it can effectively shorten equipment downtime, thereby improving equipment utilization and processing efficiency, and helping to reduce the labor intensity of operators. Attached Figure Description

[0043] Specific Implementation Example 1, such as Figures 1-6 As shown, a synchronous moving multi-spindle vertical machining center includes a frame 1, a sliding base 2, a base moving mechanism, a spindle slide 3, a slide moving mechanism, a spindle box 4, a lifting moving mechanism, a rotary table 5, and a working motor.

[0044] The sliding base 2 is slidably connected to the frame 1 in the horizontal direction. The base moving mechanism drives the sliding base 2 to move. The base moving mechanism is an electric cylinder or a linear module. Of course, the base moving mechanism can also be other linear drive mechanisms available on the market, such as a lead screw and nut linear drive mechanism.

[0045] The spindle slide 3 is slidably connected to the sliding base 2 in a horizontal direction. The sliding directions of the sliding base 2 and the spindle slide 3 are perpendicular, that is, the sliding direction of the sliding base 2 is perpendicular to the sliding direction of the spindle slide 3. The slide movement mechanism drives the spindle slide 3 to move. The slide movement mechanism is an electric cylinder or a linear module. Of course, the slide movement mechanism can also be other linear drive mechanisms available on the market, such as a lead screw and nut linear drive mechanism.

[0046] The spindle box 4 is slidably connected to the spindle slide 3 in the vertical direction. The lifting and moving mechanism drives the spindle box 4 to rise and fall. The lifting and moving mechanism is an electric cylinder or a linear module. Of course, the lifting and moving mechanism can also be other linear drive mechanisms available on the market, such as a lead screw and nut linear drive mechanism.

[0047] The spindle box 4 is provided with at least two spindle heads 4.1. For example, the spindle box 4 is provided with 2-4 spindle heads 4.1 arranged side by side. In this embodiment, the spindle box 4 is provided with two spindle heads 4.1 arranged side by side.

[0048] The rotary table 5 is rotatably mounted on the frame 1. The rotary table 5 is driven to rotate by a working motor. The working motor can directly drive the rotary table 5 to rotate, or it can drive the rotary table 5 to rotate through a transmission mechanism (such as a gear transmission mechanism or a synchronous belt transmission mechanism).

[0049] In this embodiment, the spindle box 4 of a synchronous moving multi-spindle vertical machining center has at least two spindle heads 4.1. Each spindle head 4.1 can be equipped with a cutting tool to machine the workpiece. Therefore, two or more workpieces can be machined simultaneously by using the spindle heads 4.1 on the spindle box 4, thereby improving machining efficiency. Furthermore, since each spindle head 4.1 of the spindle box 4 shares a base moving mechanism, a slide moving mechanism, and a lifting moving mechanism (i.e., each spindle head 4.1 of the spindle box 4 shares a set of X, Y, and Z axis moving mechanisms), it can effectively improve the overall structural compactness of the machining center, effectively reduce the space occupied by the machining center, and lower manufacturing costs.

[0050] On the other hand, since the workpieces are mounted on the rotatable rotary table 5, while the workpieces at one of the working positions 5.1 of each spindle head 4.1 on the spindle box 4 are being processed, the operator can disassemble the completed workpieces and install new workpieces to be processed at another working position 5.1. After each spindle head 4.1 on the spindle box 4 has completed processing of the workpieces at one working position 5.1, the operator can drive the table to rotate via the rotary drive mechanism to rotate the workpieces at another working position 5.1 to the machining position for processing, without waiting for the operator to disassemble and install workpieces. This effectively shortens equipment downtime, thereby improving equipment utilization and processing efficiency. Furthermore, since the operator disassembles and installs workpieces at another working position 5.1 during the workpiece processing process, there is ample time for disassembly and installation, allowing the operator to work in a relaxed state and reducing the operator's labor intensity.

[0051] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, the rotary table 5 has two working positions 5.1, which are located on both sides of the rotation axis of the rotary table 5. Each working position 5.1 can simultaneously mount multiple workpieces. Each spindle head 4.1 on the spindle box 4 can simultaneously process two or more workpieces on the same working position 5.1. In this embodiment, the two spindle heads 4.1 on the spindle box 4 can simultaneously process two workpieces on the same working position 5.1. Since the spindle box 4 has two spindle heads 4.1, in actual processing, the number of workpieces mounted simultaneously on each working position 5.1 is generally an even number, for example, 2, 4, or 6 workpieces mounted simultaneously on each working position 5.1. It should be noted that the number of workpieces mounted simultaneously on each working position 5.1 can also be an odd number, for example, 1, 3, or 5 workpieces mounted simultaneously on each working position 5.1.

[0052] Furthermore, such as Figure 1 , Figure 3 , Figure 4 As shown, a partition 6 is provided on the upper surface of the rotary table 5, which separates the two working positions 5.1 on the table. Thus, during the machining process of the workpiece at one working position 5.1 by the spindle heads 4.1 on the spindle box 4, the partition 6 can block the flying debris generated during machining, preventing operators from accidentally touching the high-speed rotating tool or being scratched by flying debris while operating at the other working position 5.1. This improves the safety of operators when disassembling and installing workpieces at the other working position 5.1.

[0053] Furthermore, such as Figure 1 , Figure 3 , Figure 4 As shown, the top of the partition 6 is provided with an upper baffle 6.1. A portion of the upper baffle 6.1 extends toward one of the working positions 5.1 to form a working position blocking part, and another portion of the upper baffle 6.1 extends toward the other working position 5.1 to form a working position blocking part. In this way, the working position blocking part at the top of the partition 6 can further improve the blocking effect on flying debris, preventing debris from flying upwards along the partition 6, thereby further improving the safety of the operator when performing workpiece disassembly and installation operations at the other working position 5.1.

[0054] The bottom of the partition is equipped with a mounting plate, which is connected to the upper surface of the rotary table by bolts or welding. The partition can be installed using the mounting plate, facilitating its installation. The upper baffle is perpendicular to the partition, and the mounting plate is also perpendicular to the partition.

[0055] Furthermore, such as Figure 1 , Figure 3 , Figure 4 As shown, the upper surface of each working position 5.1 of the rotary table 5 is provided with a workpiece mounting groove 5.2 or a workpiece mounting hole; that is, the upper surface of the rotary table 5 where each working position 5.1 is located is provided with a workpiece mounting groove 5.2 or a workpiece mounting hole. The workpiece mounting groove 5.2 is a T-slot or a dovetail groove.

[0056] In one example, such as Figure 1 , Figure 2 As shown, the upper surface of the workbench at each workstation 5.1 is provided with a workpiece mounting groove 5.2, which is either a T-slot or a dovetail groove. Thus, in actual use, the workpiece can be mounted on the fixture. The bottom of the fixture is provided with a T-block or dovetail block that mates with the T-slot or dovetail groove, making it easy to install the fixture onto the workpiece mounting groove 5.2, thereby facilitating workpiece installation.

[0057] In another example, the upper surface of the worktable at each workstation 5.1 is provided with workpiece mounting holes (not shown in the figure). Thus, in actual use, the workpiece can be mounted on a fixture, which is bolted to the workpiece mounting holes, facilitating workpiece installation.

[0058] It should be noted that in actual manufacturing, the tooling for clamping the workpiece can also be fixed by means of positioning pin holes or positioning slots.

[0059] Furthermore, such as Figure 1 , Figure 4As shown, a vertical receiving groove 3.1 is provided on the side of the spindle slide 3 facing the spindle box 4. The vertical receiving groove 3.1 extends through both the upper and lower ends of the spindle slide 3. The lifting and moving mechanism is arranged within the vertical receiving groove 3.1. In this way, on the one hand, the lifting and moving mechanism can be accommodated by the vertical receiving groove 3.1, thereby further improving the structural compactness and reducing the space occupied by the machining center; on the other hand, the vertical receiving groove 3.1 can also effectively reduce the weight of the spindle slide 3, and the lighter the weight of the spindle slide 3, the more conducive it is to improving the moving accuracy of the slide mechanism driving the spindle slide 3. In addition, some of the heat generated during the high-speed operation of the spindle box 4 can be discharged through the vertical receiving groove 3.1, which is beneficial to the heat dissipation of the spindle box 4.

[0060] In this second specific embodiment, the remaining structure is the same as in the first specific embodiment, except that...

[0061] like Figures 1-3 As shown, the frame 1 includes a base 1.1 and a gantry frame 1.2 mounted on the base 1.1. The base 1.1 and the gantry frame 1.2 are integrally formed; or the base 1.1 and the gantry frame 1.2 are manufactured separately, and then the base 1.1 and the gantry frame 1.2 are connected by bolts or welding. The gantry frame 1.2 includes a top beam 1.3. The top beam 1.3 is horizontally distributed. The sliding direction of the top beam 1.3 is parallel to that of the sliding base 2. Two X-axis guide rails 7 are provided on the top beam 1.3. The X-axis guide rails 7 are parallel to the top beam 1.3. The sliding base 2 slides along the X-axis guide rails 7. In this embodiment, the base moving mechanism is located between the top beam 1.3 and the sliding base 2. The spindle slide 3 is slidably connected to the sliding base 2 along the Y-axis. In this embodiment, the spindle slide 3 is slidably connected to the sliding base 2 through the Y-axis guide rail 8, and the spindle slide 3 is located above the sliding base 2. The slide table moving mechanism is located between the sliding base 2 and the main spindle slide table 3. The frame 1 structure in this embodiment can ensure the structural stability of the frame 1 structure itself.

[0062] In one embodiment of this example, as Figure 1 , Figure 2 As shown, the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the sliding direction of the sliding base 2; that is, in this embodiment, the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the X-axis guide rail 7. In this embodiment, since the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the X-axis guide rail 7, during the actual operation of the machining center, the workpieces on the same workstation 5.1 are equidistantly distributed along the X-axis guide rail 7, and the distance between any two adjacent workpieces along the X-axis guide rail 7 is the same as the distance between the two spindle heads 4.1 on the spindle box 4. Thus, the spindle heads 4.1 on the spindle box 4 can simultaneously process two or more workpieces sequentially distributed along the sliding direction of the sliding base 2.

[0063] In another embodiment of this invention, the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the sliding direction of the spindle slide 3. That is, in this embodiment, the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the Y-axis guide rail 8 (not shown in the figure). In this embodiment, because the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the Y-axis guide rail 8, during the actual operation of the machining center, the workpieces on the same workstation 5.1 are equidistantly distributed along the Y-axis guide rail 8, and the distance between any two adjacent workpieces along the Y-axis guide rail 8 is the same as the distance between the two spindle heads 4.1 on the spindle box 4. Thus, each spindle head 4.1 on the spindle box 4 can simultaneously process two or more workpieces sequentially distributed along the sliding direction of the spindle slide 3.

[0064] Furthermore, such as Figure 1 , Figure 3 As shown, there are two X-axis guide rails 7, one defined as the high-position guide rail 7.1 and the other as the low-position guide rail 7.2. The high-position guide rail 7.1 is located at a higher position than the low-position guide rail 7.2. The two X-axis guide rails 7 are distributed sequentially along the Y-axis. The sliding base 2 slides along the two X-axis guide rails 7. A bottom notch 2.1 is provided on the bottom of the sliding base 2 at a position corresponding to the high-position guide rail 7.1. The high-position guide rail 7.1 is located within the bottom notch 2.1, and the bottom notch 2.1 penetrates the sliding base 2 along the X-axis guide rail 7 direction. The arrangement of two X-axis guide rails 7 at different heights not only improves the sliding stability of the sliding base 2, but also allows for the placement of a bottom notch 2.1 on the bottom of the sliding base 2 that corresponds to the high-position guide rail 7.1, thus accommodating the high-position guide rail 7.1. This also reduces the weight of the sliding base 2, and the lighter the weight of the sliding base 2, the more effective it is in improving the movement accuracy of the base moving mechanism driving the sliding base 2.

[0065] Furthermore, one of the sliding base 2 and the main spindle slide 3 is provided with a longitudinal receiving groove extending along the Y-axis. The slide moving mechanism is arranged within the longitudinal receiving groove. Specifically,

[0066] In one example, the sliding base 2 has a longitudinal receiving groove extending along the Y-axis, with the opening of the longitudinal receiving groove facing upwards and towards the spindle slide 3. The slide moving mechanism is arranged within the longitudinal receiving groove. This not only allows for the arrangement of the slide moving mechanism via the longitudinal receiving groove, thereby further improving structural compactness and reducing the space occupied by the machining center, but also reduces the weight of the sliding base 2. A lighter sliding base 2 is more conducive to improving its movement accuracy.

[0067] In another example, the spindle slide 3 is provided with a longitudinal receiving groove extending along the Y-axis, with the opening of the longitudinal receiving groove facing downwards and towards the sliding base 2. The slide moving mechanism is arranged within the longitudinal receiving groove. In this way, not only can the slide moving mechanism be arranged using the longitudinal receiving groove, thereby further improving the structural compactness and reducing the space occupied by the machining center; but the longitudinal receiving groove can also reduce the weight of the spindle slide 3, and the lighter the weight of the spindle slide 3, the more beneficial it is to improving the moving accuracy of the spindle slide 3.

[0068] In this specific embodiment, the remaining structure is the same as in the specific embodiment, except that...

[0069] like Figures 4-6 As shown, the frame 1 includes a base 1.1, two left and right side supports 1.4 mounted on the base 1.1, and a connecting frame 1.5 connecting the two side supports 1.4. In this embodiment, the base 1.1 and the two side supports 1.4 are integrally formed; or the base 1.1 and the side supports 1.4 are manufactured separately, and then the base 1.1 and the side supports 1.4 are connected by bolts or welding. In this embodiment, the two side supports 1.4 and the connecting frame 1.5 together form a gantry structure. Y-axis guide rails 8 are respectively provided on the top of the two side supports 1.4, and the sliding base 2 is supported on the Y-axis guide rails 8 and slides along the Y-axis guide rails 8. This ensures the stability of the frame 1 itself and the smooth movement of the sliding base 2.

[0070] In this embodiment, the sliding base 2 is composed of a crossbeam. An X-axis guide rail 7 is provided on the sliding base 2. The main spindle slide 3 slides along the X-axis guide rail 7. The X-axis guide rail 7 is parallel to the crossbeam constituting the sliding base 2. The X-axis guide rail 7 includes upper and lower rails.

[0071] In this embodiment, the base moving mechanism is disposed between the frame 1 and the sliding base 2. The slide table moving mechanism is disposed between the sliding base 2 and the spindle slide table 3.

[0072] In one embodiment of this example, as Figures 4-6 As shown, the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the sliding direction of the spindle slide 3. That is, in this embodiment, the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the X-axis guide rail 7. In this embodiment, since the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the X-axis guide rail 7, during the actual operation of the machining center, the workpieces on the same workstation 5.1 are equidistantly distributed along the X-axis guide rail 7, and the distance between any two adjacent workpieces along the X-axis guide rail 7 is the same as the distance between the two spindle heads 4.1 on the spindle box 4. Thus, the spindle heads 4.1 on the spindle box 4 can simultaneously process two or more workpieces sequentially distributed along the sliding direction of the spindle slide 3.

[0073] In another embodiment of this invention, the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the sliding direction of the sliding base 2; that is, in this embodiment, the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the Y-axis guide rail 8 (not shown in the figure). In this embodiment, since the spindle heads 4.1 on the spindle box 4 are sequentially distributed along the Y-axis guide rail 8, during the actual operation of the machining center, the workpieces on the same workstation 5.1 are equidistantly distributed along the Y-axis guide rail 8, and the distance between any two adjacent workpieces along the Y-axis guide rail 8 is the same as the distance between the two spindle heads 4.1 on the spindle box 4. Thus, each spindle head 4.1 on the spindle box 4 can simultaneously process two or more workpieces sequentially distributed along the sliding direction of the sliding base 2.

[0074] In this specific embodiment four, the remaining structure is the same as in specific embodiment one, two, or three, except that...

[0075] A synchronous moving multi-spindle vertical machining center also includes a tool magazine (not shown in the figure). The spindle head 4.1 on the spindle box 4 automatically changes tools via the tool magazine. In this way, the tool magazine can be used to automatically change tools for the spindle head 4.1 to perform different machining operations such as boring, milling, drilling, and tapping.

[0076] In this embodiment, the spindle head 4.1 includes a spindle rotatably mounted on the spindle housing 4 and a spindle motor that drives the spindle to rotate. In this embodiment, the spindles are vertically distributed. Each spindle can be equipped with a cutting tool to process the workpiece.

[0077] The synchronous movement in the title "A Synchronous Moving Multi-Spindle Vertical Machining Center" refers to the synchronous movement of each spindle head 4.1 on the spindle box 4 along with the spindle box in the X, Y, and Z axis directions.

[0078] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
