A table mechanism 40 is provided on the second drive unit 30. The table mechanism 40 is a multi-modular table. A gantry frame 50 is provided at the rear end above the base 10. A working unit 60 is provided on the gantry frame 50.

[0039] like Figure 3 As shown, the base 10 is provided with a linear guide rail 11, a first drive unit 12, a ball screw 13, and an anti-collision rubber seat 14.

[0040] The linear guide rails 11 are located on the left and right sides above the base 10. The linear guide rails 11 assist the first drive unit 12 in making the saddle 20 slide back and forth.

[0041] The linear guide rail 11 is provided with a slider 111, which is connected to the saddle 20. The slider 111 serves to connect the saddle 20 to the linear guide rail 11.

[0042] The linear guide rail 11 is provided with a first drive unit 12 in the middle. The first drive unit 12 is provided with a ball screw 13. The ball screw 13 is connected to the saddle 20. The first drive unit 12 drives the ball screw 13 to rotate, thereby driving the saddle 20 to move back and forth.

[0043] The ball screw 13 is provided with an anti-collision rubber seat 14 at one end near the first drive unit 12. The anti-collision rubber seat 14 serves to limit the range of motion of the saddle 20.

[0044] The saddle 20 has a groove with an upward opening in the middle. The saddle 20 is movably mounted on the base 10 via the slider 111. The saddle 20 serves to support and fix the second drive unit 30 and the platform mechanism 40. At the same time, the saddle 20 also drives the platform mechanism 40 to move back and forth.

[0045] The saddle 20 is provided with a connecting block 21, a limiting rail 22, and a sliding seat 23.

[0046] The connecting block 21 is fixedly disposed below the middle position of the saddle 20. The connecting block 21 has a round hole in the middle for fitting onto the ball screw 13. The connecting block 21 serves to connect the saddle 20 and the ball screw 13.

[0047] The limiting rail 22 is located above the saddle 20. The limiting rail 22 is provided with a plurality of sliding seats 23 for connecting the platform mechanism 40 to the limiting rail 22. The limiting rail 22 assists the second drive unit 30 in moving the platform mechanism 40 left and right on the saddle 20.

[0048] There are multiple second drive units 30, which are located in the groove in the middle of the saddle 20 and are respectively connected to the corresponding worktable. The second drive unit 30 plays the role of driving a single worktable to move left and right with the assistance of the limiting rail 22.

[0049] The second drive unit 30 consists of a motor 31, a sliding lead screw 32, and a mating block 33.

[0050] The motor 31 drives the sliding lead screw 32 to rotate. The sliding lead screw 32 is connected to the worktable through its own sliding block, so that the worktable moves left and right under the action of the motor 31. The other end of the sliding lead screw 32 is provided with a mating block 33, which serves to support the sliding lead screw 32.

[0051] The table mechanism 40 consists of multiple worktables. In this embodiment, the table mechanism consists of three worktables. The table mechanism 40 is movably mounted on the saddle 20 via the limiting rail 22. The table mechanism 40 serves to fix the workpiece to be processed.

[0052] like Figures 4-6 As shown, the table mechanism 40 consists of a first worktable 41, a second worktable 42, a third worktable 43, a coupling block 44, and a third drive unit 45.

[0053] The workbench 41 is movably mounted on the saddle 20 via the limiting rail 22 and is connected to the corresponding second drive unit 30. The workbench 41 can move left and right along the limiting rail 22 under the driving action of the corresponding second drive unit 30.

[0054] The workbench 41 is provided with an upper sliding plate 411, a diagonal strip 412, a protective cover 413, and a lower sliding plate 414 below it.

[0055] The bottom of the workbench 41 is provided with a downward-opening groove, and one side wall of the groove is stepped, while the other side wall is an inwardly inclined slope.

[0056] The upper slide plate 411 is located below the worktable 41. The left side of the upper slide plate 411 has a through hole for installing the third drive mechanism 45. A protrusion is formed on the upper surface of the upper slide plate 411 to cooperate with the bottom groove of the worktable 41. The length of the protrusion is less than the length of the bottom groove of the worktable 41. When the worktable 41 is installed on the upper slide plate 411, a parallelogram cavity is formed between the worktable 41 and the upper slide plate 411. The oblique insert 412 is located in the parallelogram cavity. The oblique insert 412 serves to restrict the worktable 41 to the upper slide plate 411 and allows the worktable 41 to slide back and forth along the oblique insert 412.

[0057] The protective cover 413 is located below the upper slide plate 411. One side of the protective cover 413 is fixedly connected to the second worktable 42. When the upper slide plate 411 moves the first worktable 41 left and right, the protective cover 413 is fixed. The protective cover 413 prevents water, debris and other substances from entering the groove in the saddle 20 during the processing, thereby affecting the operation of the second drive unit 30.

[0058] The lower slide plate 414 is provided below the protective cover 413. The lower slide plate 414 is fixedly connected to the upper slide plate 411 through the side wall. The bottom of the lower slide plate 414 is provided with a coupling block 44. The coupling block 44 is sleeved on the sliding block on the sliding screw 32. Under the transmission action of the sliding screw 32, the lower slide plate 414 drives the upper slide plate 411 to move left and right, thereby causing the worktable 41 to move left and right along the limiting track 22.

[0059] The third drive unit 45 is located in the through hole on the left side of the upper slide plate 411. The third drive unit 45 is provided with a nut seat 451, which is fixedly connected to the worktable 41. The third drive unit 45 drives the nut seat 451 to adjust the position of the nut seat 451 on the third drive unit 45, thereby causing the nut seat 451 to drive the worktable 41 to move back and forth along the inclined strip 412.

[0060] The second workbench 42 is located on one side of the first workbench. The bottom of the second workbench 42 is provided with an extension block 421. The extension block 421 is fixedly connected to the sliding seat 23 on the limiting rail 22. The bottom of the second workbench is also provided with a coupling block 44 to connect the second workbench 42 to the corresponding second drive unit 30.

[0061] The structure of workbench 3 43 is the same as that of workbench 1 41, and it is located on one side of workbench 2 42.

[0062] The gantry frame 50 is fixedly mounted on the base 10, and the gantry frame 50 serves to support the working unit 60.

[0063] The working unit 60 is fixedly mounted on the gantry frame 50, such as Figure 7 As shown, the working unit consists of a crossbeam 61, a slide rail 62, a fourth drive unit 63, a first spindle box 64, a second spindle box 65, a third spindle box 66, and a tool magazine 67.

[0064] There are multiple crossbeams 61, which are fixedly installed on the gantry frame 50. The crossbeams 61 serve to fix and support the slide rail 62 and the fourth drive unit 63.

[0065] A vertical slide rail 62 is fixedly provided in front of the crossbeam 61. A moving block 621 is provided on the slide rail 62. The moving block 621 is fixedly connected to the spindle box. The slide rail 62 serves to assist the fourth drive unit 63 in driving the spindle box to move up and down.

[0066] The fourth drive unit 63 is located on the top of the crossbeam 61. The fourth drive unit 63 is equipped with a Z-axis lead screw 631, which is connected to the spindle box. The Z-axis lead screw 631 drives the spindle box to move up and down.

[0067] The spindle box 64 is connected to the crossbeam 61 via the slide rail 62. The spindle box 64 serves to fix and drive the cutter head. The structural design of the spindle box 64 places the cutter head on one side of the spindle box 64, thereby keeping the cutter head on the spindle box 64 away from the cutter heads of other spindle boxes and reserving sufficient space for the cutter heads on other spindle boxes to work.

[0068] A tool magazine bracket 641 is fitted onto the spindle box 64. The tool magazine bracket 641 is fixed to the crossbeam 61. The tool magazine bracket 641 serves to fix the tool magazine 67 and also to match the position of the tool magazine 67 with the position of the tool head on the spindle box 64.

[0069] The second spindle box 65 is mounted on the middle crossbeam 61. The structural design of the second spindle box 65 positions the tool head directly in front of the second spindle box 65. A tool magazine bracket 651, which is fixed to the crossbeam 61, is fitted onto the second spindle box 65. The tool magazine bracket 651 fixes the tool magazine 67 directly in front of the second spindle box 65, thereby matching the position of the tool magazine 67 in front of the second spindle box 65 with the position of the tool head on the second spindle box 65.

[0070] The spindle box 366 is equipped with a tool magazine bracket 3661. The spindle box 366 is symmetrically arranged with the spindle box 1 64, so that the tool heads on the spindle box 366 can be kept away from other tool heads, so that each tool head can work freely.

[0071] There are multiple tool magazines 67, each mounted on a corresponding tool magazine bracket. The tool magazine 67 serves to store tool heads and to cooperate with the corresponding spindle box for tool head replacement.

[0072] The working principle of this utility model is as follows: A multi-station CNC machine tool, under program control, allows multiple spindle heads to move independently up and down along the slide rail 62 under the drive of the fourth drive unit 63. The saddle 20, under the action of the first drive unit 12 on the base 10, can drive the table mechanism 40 to move back and forth to cooperate with the spindle heads. Simultaneously, under the drive of the third drive unit 45, worktables 1 and 3 can move independently back and forth along the inclined strip 412, making the spindle heads more flexible and efficient in machining workpieces. Under the control of the second drive unit 30, multiple tables can move independently and flexibly left and right to cooperate with the spindle heads. Meanwhile, the guard... The cover 413 effectively prevents water, debris, and other contaminants from entering the saddle 20, ensuring the stable operation of the second drive unit 30. With multiple spindle boxes and modular worktables, multiple spindle boxes can simultaneously process multiple workpieces, improving the drilling and tapping machine's efficiency and significantly saving space and reducing labor costs. The gantry 50 replaces the traditional column in the drilling and tapping machine. Multiple worktables can move freely forward, backward, left, and right to coordinate with the spindle boxes, allowing the Y-axis beam to adopt a fixed structure, greatly improving the rigidity of the drilling and tapping machine.

[0073] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0074] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
