[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example 1, referring to Figure 1-4 A CNC machining center bed includes an L-shaped bed 1. A rectangular frame 2 is installed on the upper surface of the horizontal section of the L-shaped bed 1. A serpentine cooling pipe 21 is fixed on the upper surface of the rectangular frame 2. A support plate 11 is fixed above the serpentine cooling pipe 21. A U-shaped connecting seat 6 is fixed on the upper surface of the support plate 11. An auxiliary bracket is installed on one side of the U-shaped connecting seat 6.
[0021] Connecting the two ends of the serpentine cooling pipe 21 to an external circulating cooling system allows the coolant to flow in the serpentine cooling pipe 21, effectively removing heat from the L-shaped bed 1, rectangular frame 2, and support plate 11, thus effectively reducing the local temperature and controlling thermal deformation.
[0022] A first rubber pad 12 is fixed at each of the four corners of the lower end face of the rectangular frame 2, and a second rubber pad is fixed between each of the four corners of the rectangular frame 2 and the support plate 11.
[0023] Positioning rods 10 are fixed at the four corners of the upper surface of the horizontal section of the L-shaped bed 1. The four corners of the rectangular frame 2 and the support plate 11 are respectively fitted onto the four positioning rods 10, which facilitates the fixing of the rectangular frame 2 and the support plate 11 and also enables quick disassembly. The first rubber pad 12 and the second rubber pad can reduce the vibration of the bed and reduce the impact on the workpiece processing.
[0024] The auxiliary bracket includes a U-shaped rod 8 fixed to one side of the U-shaped connecting seat 6. A threaded rod 9 is rotatably connected to one side of the U-shaped connecting seat 6 via a bearing. A servo motor is installed in the middle of the U-shaped rod 8. The output end of the servo motor is connected to one end of the threaded rod 9. A T-shaped movable seat 7 is screwed onto the threaded rod 9. The two ends of the T-shaped movable seat 7 slide against the upper surfaces of the two sides of the U-shaped rod 8.
[0025] By activating the servo motor, the threaded rod 9 is driven to rotate, which in turn drives the T-shaped movable seat 7 to move, thereby achieving fine-tuning of the position.
[0026] Two fixed seats 5 are symmetrically fixed on the upper end of the horizontal section of the T-shaped movable seat 7. An adjusting plate 17 is rotatably connected between the two fixed seats 5 by a connecting pin. One end of the adjusting plate 17 has an installation port, and the upper end of the T-shaped movable seat 7 near the installation port has an installation groove 19.
[0027] A U-shaped support 14 is fixed in the mounting slot 19, and a connecting rod 18 is fixed at the mounting opening. A connecting sleeve is slidably connected to the connecting rod 18. A first electric push rod 20 is rotatably mounted on the U-shaped support 14, and one end of the first electric push rod 20 is fixedly connected to the connecting sleeve.
[0028] By controlling the extension and retraction of the first electric push rod 20, the adjusting plate 17 can be rotated slightly, which helps to adjust the level of the adjusting plate 17. The workpiece to be processed can be placed on the adjusting plate 17. By assembling a lathe-specific fixture on the adjusting plate 17, the workpiece can be clamped and fixed.
[0029] Example 2 is an optimization based on Example 1, specifically:
[0030] A fixing rod 3 is installed on the top of the U-shaped connecting seat 6. A rotating sleeve 4 is slidably sleeved on the fixing rod 3. A bending plate 13 is connected to the rotating sleeve 4. The horizontal section of the bending plate 13 is slidably inserted into the T-shaped movable seat 7. A second electric push rod 15 is installed on one side of the vertical section of the bending plate 13. One end of the second electric push rod 15 is connected to a mounting base. A level 16 is fixed on the mounting base.
[0031] The level 16 can be used to help calibrate whether the adjustment plate 17 is level. By controlling the extension and retraction of the second electric push rod 15, the distance between the level 16 and the adjustment plate 17 can be easily adjusted.
[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
