[0002] A five-axis machine tool is a CNC machine tool that has five independent axes of motion. Generally speaking, these five axes are X-axis, Y-axis, Z-axis and two rotation axes, usually marked as A-axis and C-axis. This design allows high-precision machining of workpieces in multiple directions, including complex movements such as rotation and tilt. The fixed frame is part of the machine bed, which is used to support and fix the other components of the machine tool to ensure that the machine tool can maintain accurate position and posture during the machining process;

[0003] With respect to the above-mentioned related technologies, the inventor believes that although the existing machine tool fixing frame can stably support and fix the machine tool, the fixing frame structure is relatively fixed and is customized according to the machine tool of corresponding size. Therefore, when replacing a different machine tool, it is necessary to replace a fixing frame of different size, which is relatively inconvenient in overall operation and increases the actual use cost accordingly.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0008] Preferably, the braking component includes a brake motor, a fixed rod, a worm and a worm wheel. The brake motor is fixedly connected to the bottom of the inner cavity of the control box by bolts. The brake motor is fixedly connected to the fixed rod by an output shaft. The end of the fixed rod away from the brake motor is rotatably connected to the inner cavity side wall of the control box by a rotating shaft.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a five-axis machine tool fixing frame. Figure 1-3 A five-axis machine tool fixed frame includes a base 1, a support frame 2 is fixedly connected to the top of the base 1, a control box 3 is fixedly connected to one side of the support frame 2 by bolts, two sets of sliding grooves 4 are opened on the top of the support frame 2, and the inner cavity side walls of the two sets of sliding grooves 4 are rotatably connected with bidirectional threaded rods 5 through a rotating shaft, and one end of the two sets of bidirectional threaded rods 5 close to the control box 3 rotates through the sliding groove 4 and extends to the inside of the control box 3, and one end of the two sets of bidirectional threaded rods 5 passing through the sliding groove 4 is provided with a brake, and the brake is arranged inside the control box 3, and a limit groove 8 is opened on the top of the support frame 2, and a fixing piece is arranged inside the limit groove 8, and the fixing piece The fixed parts are arranged on the surfaces of the two groups of bidirectional threaded rods 5, and the brake parts include a brake motor 11, a fixed rod 12, a worm 13 and a worm wheel 14. The bottom of the inner cavity of the control box 3 is fixedly connected with the brake motor 11 by bolts, and the brake motor 11 is fixedly connected with the fixed rod 12 by an output shaft. One end of the fixed rod 12 away from the brake motor 11 is rotatably connected to the inner cavity side wall of the control box 3 by a rotating shaft, and the surface of the fixed rod 12 is fixedly connected with two groups of worms 13, and the surfaces of the two groups of worms 13 are meshed with worm wheels 14, and one side of the two groups of worm wheels 14 is fixedly connected to one end of the bidirectional threaded rod 5 passing through the sliding groove 4 by bolts;

[0020] By adopting the above technical scheme, it is convenient to fix the whole machine tool through the base 1 and the support frame 2, and the base 1 and the support frame 2 adopt a semi-hollow design, which can ensure the normal circulation of air at the bottom of the machine tool when the machine tool is fixed and supported, and can prevent the floor of the workshop from being damp, etc., which accelerates the corrosion of the bottom of the machine tool. When machine tools of different sizes are replaced, the brake motor 11 fixedly connected to the bottom of the inner cavity of the control box 3 can be output, which can drive the fixed rod 12 and the two groups of worm gears 13 fixedly connected to its surface to rotate. At this time, the two-way threaded rod 5 in the sliding groove 4 can be driven to rotate through the two groups of worm gears 14, so that the fixing parts can be moved and adjusted, and the stability of the fixing parts during movement can be improved through the limit groove 8, which can provide more stable support for the machine tool.

[0021] Reference Figure 1 and Figure 2 The fixing parts include a threaded sleeve 10, a fixing plate 6, a fixing pad 7 and a T-shaped slider 9. The inner cavity side wall of the limiting groove 8 is slidably connected with two groups of T-shaped sliders 9. The tops of the two groups of T-shaped sliders 9 are fixedly connected with the fixing plate 6. The top of the fixing plate 6 is fixedly connected with the fixing pad 7. The bottom of the fixing plate 6 is fixedly connected with two groups of threaded sleeves 10 by bolts. The inner cavity side walls of the two groups of threaded sleeves 10 are threadedly connected to the surface of the bidirectional threaded rod 5.

[0022] By adopting the above technical scheme, since the surfaces of the two groups of bidirectional threaded rods 5 are provided with two groups of opposite thread patterns, when the two groups of bidirectional threaded rods 5 rotate, the threaded sleeves 10 respectively threadedly connected to the surfaces of the two groups of bidirectional threaded rods 5 can drive the two groups of fixed plates 6 to move inward or outward at the same time, and the distance between them can be adjusted. At this time, the T-shaped slider 9 at the bottom of the fixed plate 6 can move in its limiting groove 8 at the same time, which can improve the stability of the fixed plate 6 during the movement and further improve the supporting stability of the machine tool. At the same time, the provided fixing pad 7 can play a corresponding anti-slip role and can also reduce the friction loss caused by equipment vibration during the use of the machine tool.

[0023] The implementation principle of a five-axis machine tool fixing frame in the embodiment of the present application is as follows: the base 1 and the support frame 2 are used to fix the five-axis machine tool as a whole, and the base 1 and the support frame 2 are designed to be semi-hollow, so that the air at the bottom of the machine tool can be ensured to circulate normally when the machine tool is fixed and supported, and the moisture on the floor of the workshop can be prevented, which accelerates the corrosion of the bottom of the machine tool. When machine tools of different sizes are replaced, the output can be obtained through the brake motor 11 fixedly connected to the bottom of the inner cavity of the control box 3, which can drive the fixing rod 12 and the two groups of worm gears 13 fixedly connected to the surface to rotate. At this time, the two-way threaded rod 5 in the sliding groove 4 can be driven to rotate through the two groups of worm gears 14. Because the surfaces of the two groups of two-way threaded rods 5 are provided with two groups of opposite thread patterns, when the two groups of two-way threaded rods 5 rotate, the two groups of two-way threaded rods 5 can be driven to rotate through their two The threaded sleeves 10 respectively threadedly connected on the surfaces of the two-way threaded rods 5 can drive the two sets of fixed plates 6 to move inward or outward at the same time, and the distance between them can be adjusted. At this time, the T-shaped slider 9 at the bottom of the fixed plate 6 can move in its limiting groove 8 at the same time, which can improve the stability of the fixed plate 6 during the movement, and further improve the supporting stability of the machine tool. At the same time, the fixed pad 7 can play a corresponding anti-slip role, and at the same time, it can also reduce the friction loss caused by the vibration of the equipment during the use of the machine tool. It can be adjusted according to a variety of machine tools of different sizes, and the machine tool can be stably supported and fixed. The operation is more convenient and the use cost is effectively reduced. At the same time, it can also reduce the friction loss and corrosion during the use of the machine tool, and correspondingly increase its service life.
