Description

Technical Field

[0001] The utility model relates to the technical field of gantry machining centers, in particular to a mobile gantry machining center. Background Art

[0002] The gantry machining center is a high-efficiency, precision large-scale machine tool, which is widely used in aerospace, automobile manufacturing, mold processing and other fields.

[0003] According to the existing technology, although the gantry machining center has certain advantages, there are still some problems that need to be solved. For example, when the gantry machining center works for a long time, the workpiece will vibrate at a high frequency on the processing table or the fixed plate. The high-frequency vibration will cause the temperature of the workbench to rise. The temperature rise will cause the processing table or the fixed plate to deform thermally. The thermal deformation will cause the workpiece to shift. In the aerospace field, the dimensional error requirements are extremely high. Once the workpiece shifts, the processing accuracy will be reduced, resulting in the workpiece being scrapped and unusable, and then needing to be reprocessed, which will not only increase the cost of production and processing, but also reduce the yield of production and processing.

The blades can drive the rotating rod to rotate when the blades rotate, and the rotating rod can drive the fan blades to rotate when the rotating rod rotates. The residual hot air is transferred out of the exhaust hole through the guidance of the fan blades, and the heat in the fixed plate is quickly discharged, ensuring that the fixed plate will not be thermally deformed due to excessive heat, thereby ensuring that the workpiece can be stably placed on the fixed plate, ensuring the accuracy of production and processing, and ensuring the quality of the finished products of production and processing.

Then the vibration on the fixed plate will transmit the vibration force to the sliding ball. The sliding ball will move up and down with the vibration force to offset the vibration force. In this way, the vibration amplitude of the fixed plate can be reduced, the impact of the vibration on the fixed plate can be reduced, and the service life of the fixed plate can be ensured.

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0023] A mobile gantry machining center provided by some embodiments of the present utility model will be described below in conjunction with the accompanying drawings.

[0024] Combination Figure 1-3 As shown, a mobile gantry machining center provided by the utility model comprises a base 1, the top of the base 1 is symmetrically fixedly connected with a track 2, the inner wall of the track 2 is fitted and slidably connected with a moving bar 3, a fixed plate 4 is fixedly connected between the moving bars 3, the inner wall of the fixed plate 4 is rotatably connected with a rotating rod 7, one end of the rotating rod 7 is fixedly connected with a blade 6, one end of the rotating rod 7 is fixedly connected with a fan blade 8, one side of the blade 6 is fitted and slidably connected with a cooling pipe 5, both ends of the cooling pipe 5 are fixedly connected to the two ends of the moving bar 3, and the bottom of the moving bar 3 and the base 1 are arranged in a connected shape;

[0025] A slider 11 is fixedly connected to the bottom of the fixed plate 4, one end of the slider 11 is slidably connected to the top of the base 1, gantry 12 is fixedly connected to both sides of the base 1, one side of the gantry 12 is fixedly connected to a driving block 13, one side of the driving block 13 is rotatably connected with a threaded rod 14 in a through-like manner, one end of the threaded rod 14 is threadedly connected to a moving block 15 in a through-like manner, one side of the moving block 15 is slidably connected with a control box 16, and a processing head 17 is provided at the bottom of the control box 16, exhaust holes 18 are opened on the side wall of the fixed plate 4, and the number of moving bars 3 is two, and both ends of the cooling pipe 5 are fixedly connected to the bottom of the moving bar 3 in a through-like manner, and both ends of the cooling pipe 5 are slidably connected to the top of the base 1 in a through-like manner.

[0026] In the first embodiment, when the coolant in the base 1 passes through the cooling tube 5, the flowing coolant will push the blade 6 to move. When the blade 6 is pushed, the rotating rod 7 can be rotated. When the rotating rod 7 is rotated, the fan blade 8 can be driven to rotate. In this way, the heat inside the fixed plate 4 can be taken away by the coolant when it moves, and the remaining hot air can be blown out of the fixed plate 4 through the exhaust hole 18. In this way, the temperature in the fixed plate 4 can be kept constant, and the temperature will not rise due to long-term processing, causing thermal deformation of the fixed plate 4, thereby ensuring the stable placement of the workpiece, ensuring the accuracy of production and processing, reducing the occurrence of defective products, and ensuring the quality of production and processing.

[0027] A cavity is formed at the bottom of the fixed plate 4 , and sliding rods 9 are fixedly connected to the inner wall of the fixed plate 4 in sequence. A sliding ball 10 is slidably connected to one end of the sliding rod 9 in a penetrating manner.

[0028] In the second embodiment, when the fixed plate 4 is driven by the workpiece to vibrate, the vibration force will be transmitted to the inside of the fixed plate 4, and then the force will act on the sliding ball 10. The sliding ball 10 can generate resistance when vibrating to offset the vibration force of the fixed plate 4, thereby reducing the vibration amplitude of the fixed plate 4, ensuring the strength of the fixed plate 4, and extending the service life of the fixed plate 4.

[0029] The working principle and use process of the utility model are as follows: when the coolant passes through the cooling tube 5, the cooling tube 5 will push the blades 6 to move when it flows, and the blades 6 can drive the rotating rod 7 to rotate when moving, and the rotating rod 7 can drive the fan blades 8 to rotate when rotating, and the fan blades 8 can discharge the hot air in the fixed plate 4 through the exhaust holes 18 when rotating, and at the same time, the fixed plate 4 can transmit the vibration force to the sliding ball 10 when vibrating, and the sliding ball 10 will also generate a vibration force when vibrating up and down, and the collision of the two forces can offset each other, although they cannot completely offset each other, the vibration force of the fixed plate 4 can be reduced.
