Description

Technical Field

[0001] This utility model relates to the field of lathe technology, specifically to a dual-spindle CNC lathe with a tool post mounting structure. Background Technology

[0002] A lathe is a machine tool that primarily uses a cutting tool to machine rotating workpieces. The lathe rotates the workpiece while simultaneously using a cutting tool to machine its surface. The workpiece is typically fixed to the spindle, and the spindle's rotation generates the cutting motion, while the cutting tool moves laterally, longitudinally, or obliquely upwards, thus enabling machining processes such as cutting, turning, drilling, and tapping.

[0003] Among the types of lathes, there are slant lathes, which are lathe beds with a flat slide that is inclined. With the same guide rail width, the X-direction slide of a slant lathe is longer than that of a flat lathe, so more tools can be arranged. Therefore, multiple tool holders need to be installed to fix the tools. The current installation of tool holders involves installing multiple bolts around the outside for fastening. The installation process is cumbersome, and the efficiency is low when replacing and disassembling them. Utility Model Content

[0004] The purpose of this invention is to provide a dual-spindle CNC lathe with a tool post mounting structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-spindle CNC lathe with a tool post mounting structure, comprising:

[0006] The bed frame has a slanted main frame fixed to its top.

[0007] There are two spindles, located at both ends of the bed;

[0008] A movable stage is slidably positioned on the outside of the inclined main frame, and a servo slide table two for driving the movable stage is fixedly connected to the outside of the inclined main frame.

[0009] A support frame is fixed to the outside of the moving stage. Two servo slides are fixed to the top of the support frame. A mounting plate is fixed to the slide of each servo slide. A T-shaped block is installed inside the mounting plate. A mounting seat is fixedly connected to the top of the T-shaped block. A lead screw is rotatably connected to the top of the mounting seat. A tool holder is threaded to the outside of the lead screw. The tool holder is slidably connected to the mounting seat.

[0010] Preferably, the spindle includes a first spindle and a second spindle, the second spindle being slidably disposed on the outside of the moving stage, and the first spindle and the second spindle being coaxially disposed.

[0011] Preferably, a fixed spindle support is fixedly connected to one end of the top of the bed, and the spindle is installed in the middle of the fixed spindle support.

[0012] Preferably, a movable spindle support is slidably connected to the top of the movable stage, the second spindle is installed in the middle of the movable spindle support, and a servo slide table for driving the movable spindle support is installed on the top of the movable stage.

[0013] Preferably, the top of the mounting plate is provided with multiple inverted T-shaped grooves at equal intervals, and the T-shaped blocks are slidably connected to the grooves. The bottom of the tool holder is provided with a lifting groove that cooperates with the mounting base, and the lifting groove is fixed to the mounting plate by a lead screw.

[0014] Preferably, a mounting bracket is fixedly connected to the top of the tool holder, a geared motor is fixedly connected to the side of the tool holder, and a tool disc is fixedly connected to the output end of the geared motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The inclined main frame is fixed to the top of the bed. With the same guide rail width, the X-axis slide of the inclined bed is longer than that of the flat bed, allowing for more tool positions and meeting the needs of complex machining for various tools. Two symmetrically mounted and coaxial spindles (spindle one and spindle two) at both ends of the bed can simultaneously fix both ends of the workpiece, meeting the needs of scenarios where both ends of the workpiece require synchronous machining. Spindle two is slidably positioned outside the moving table, and the spindle support is moved by servo slide one. The position of spindle two can be adjusted using the servo control system, allowing for flexible adjustment according to the machining requirements of different workpieces, enhancing the equipment's versatility and adaptability. A T-block is slid into the inverted T-shaped groove from one end of the mounting plate. Rotating the lead screw causes the tool holder to move downwards along the mounting base, engaging the T-block in the groove. The mounting plate is then clamped between the T-block and the tool holder, allowing for quick tool fixation via the lead screw, eliminating the need for multiple screws, saving time and effort, and improving tool installation efficiency.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a dual-spindle CNC lathe with a tool holder mounting structure, comprising: a bed 1, with an inclined main frame 20 fixedly connected to the top of the bed 1, the inclined main frame 20 forming a right-angled triangle with the bed. With the same guide rail width, the X-axis slide of the slant bed is longer than that of the flat bed, which can accommodate more tool positions; there are two spindles, and the two spindles are symmetrically installed at both ends of the bed 1; the moving table 4 is slidably installed on the outside of the slant main frame 20, and a servo slide 2 8 that drives the moving table 4 is fixedly connected to the outside of the slant main frame 20. The servo slide 2 8 is located at the end opposite to the servo slide 1 6. The support frame 9 is fixedly connected to the outside of the moving table 4, and two parallel servo slides 3 10 are fixedly connected to the top of the support frame 9. A mounting plate 11 is fixedly connected to the slide of the servo slide 3 10. A T-block 13 is detachably installed inside the mounting plate 11. A mounting seat 12 is fixedly connected to the top of the T-block 13. A lead screw 16 is rotatably connected to the top of the mounting seat 12. A tool holder 14 is threadedly connected to the outside of the lead screw 16. The tool holder 14 is slidably connected to the mounting seat 12.

[0024] It should be noted that in this embodiment, the two spindles are coaxially arranged, and the corresponding workpieces can be fixed by chucks. When installing and fixing the tool holder 14, the T-block 13 is slid into one end of the mounting plate 11, so that the T-block 13 hooks into the mounting plate 11. Then, the screw 16 is tightened, so that the tool holder 14 moves along the mounting base 12. Under the action of the screw and reaction, the bottom of the mounting base 12 contacts the mounting plate 11, and the bottom of the tool holder 14 presses against the mounting plate 11, thereby quickly fixing the tool holder 14 to the top of the mounting plate 11. The displacement of the moving table 4 driven by the servo slide 2 8 and the displacement of the mounting plate 11 can drive the tool and the workpiece to cooperate for processing.

[0025] In one embodiment, the spindle includes a first spindle 3 and a second spindle 7. The second spindle 7 is slidably disposed on the outside of the moving table 4. The first spindle 3 and the second spindle 7 are coaxially disposed. A fixed spindle support 2 is fixedly connected to one end of the top of the bed 1. The first spindle 3 is installed in the middle of the fixed spindle support 2. A moving spindle support 5 is slidably connected to the top of the moving table 4. The second spindle 7 is installed in the middle of the moving spindle support 5. A servo slide 6 that drives the moving spindle support 5 is installed on the top of the moving table 4.

[0026] It should be noted that in this embodiment, spindle 3 and spindle 7 are coaxially arranged and aligned along the same axis, allowing them to simultaneously fix both ends of the workpiece. The fixed spindle support 2 is installed at one end of the top of the bed 1, and spindle 3 is installed in the middle of this fixed spindle support 2, ensuring the stability of spindle 3. The servo slide 6 drives the movable spindle support 5, using a servo control system to adjust the spindle position. This allows the movable spindle support 5 to move smoothly as needed, and the positions of the movable spindle support 5 and spindle 7 can be adjusted as required to reach the designated positions.

[0027] In one embodiment, the top of the mounting plate 11 is provided with a plurality of inverted T-shaped grooves at equal intervals, the T-shaped block 13 is slidably connected to the grooves, and the bottom of the tool holder 14 is provided with a lifting groove 15 that cooperates with the mounting base 12. The lifting groove 15 is fixed to the mounting plate 11 by the lead screw 16.

[0028] It should be noted that in this embodiment, the T-shaped block 13 is slid from one end of the mounting plate 11 into the groove of the inverted T-shaped structure. With the cooperation of the lifting groove 15 and the mounting base 12, the rotating screw 16 causes the tool holder 14 to move downward along the mounting base 12, and the T-shaped block 13 is engaged in the groove of the inverted T-shaped structure. In this way, the mounting plate 11 is clamped between the top of the T-shaped block 13 and the tool holder 14, and the lifting groove 15 is fixedly installed on the top of the mounting plate 11. The cooperation between the mounting base and the T-shaped block ensures the stability of the connection between the tool holder and the mounting plate, ensuring that the tool holder will not loosen during the processing, thereby improving the processing accuracy and safety.

[0029] In one embodiment, a mounting bracket 17 is fixedly connected to the top of the tool holder 14, a geared motor 18 is fixedly connected to the side of the tool holder 14, and a tool disc 19 is fixedly connected to the output end of the geared motor 18.

[0030] It should be noted that in this embodiment, the reduction motor 18 is a worm gear reduction motor, which effectively slows down the rotation speed of the cutter head. The reduction motor 18 drives the cutter head 19 to rotate. Multiple mounting slots for mounting tools are opened on the outer side of the cutter head 19. The tools are installed in the mounting slots. The reduction motor 18 drives the cutter head 19 to switch the tools. The servo slide 10 drives the mounting plate 11 to make the tools cooperate with the workpiece.
