Description

Technical Field

[0001] This utility model relates to the field of cooling technology for gantry machining centers, and in particular to a cooling control device for gantry machining centers. Background Technology

[0002] A gantry machining center is a machining center in which the spindle axis is set perpendicular to the worktable. It is mainly suitable for machining large parts. When machining workpieces, the gantry machining center needs to cool the workpiece surface to improve the quality of workpiece machining. In the refrigeration industry, cooling methods are divided into two types: air cooling and water cooling.

[0003] A utility model patent with authorization announcement number CN222986453U discloses a cooling device for a gantry machining center, including a base plate. A filter assembly is fixedly connected inside the base plate, comprising a filter screen, a mounting plate, and a drain outlet. A drive assembly is also fixedly connected inside the base plate, comprising a servo motor A, a transmission rod, and a threaded rod. This gantry machining center cooling device, through the arrangement of the cooling and lifting assemblies, operates by connecting a power source and activating an electric push rod. The electric push rod drives the placement plate to rise and fall, causing a flow pipe placed on the placement plate to move along with it. Simultaneously, a water pump is activated, transporting coolant from the storage tank to a spray frame through the flow pipe. The spray frame sprays coolant onto the drill bit. The electric push rod's ability to raise and lower the spray frame allows the device to adjust its height according to the workpiece being processed, ensuring accurate spraying of coolant onto the machining area and thus improving the cooling effect.

[0004] However, the above-mentioned device uses a rotary motor to drive a drill bit to process the workpiece on the upper part of the fixed plate. However, the debris generated during the processing can easily enter the upper part of the bottom plate, which can easily cause the threaded rod to jam, thus damaging the device. Utility Model Content

The filter screen can then be removed from the collection frame for easy replacement or cleaning. The operator can then use a suction device to extract the collected coolant from the collection frame and re-inject it into the liquid tank for reuse, thereby reducing coolant waste and allowing the coolant to be used multiple times, thus reducing processing costs.

[0020] A slide rail 2 is provided on the upper end of the base plate 1. The first ball screw 4 is rotatably inserted into the slide rail 2. A slide rod is fixedly provided at one end of the slide rail 2 opposite to the first ball screw 4. Two sets of symmetrical slide sleeves are movably fitted on the outer wall of the slide rod. The slide sleeves are fixedly connected to the bottom end of the collection frame 61. The first ball screw sleeve 5 and the slide sleeve are movably inserted into the inner wall of the slide rail 2. Fixing blocks 62 are fixedly provided at the four corners of the bottom end of the filter screen 63 on the inner wall of the collection frame 61. The filter screen 63 overlaps the upper end of the fixing blocks 62. The filter screen 63 is made of activated carbon. Two sets of symmetrical positioning rods 65 are fixedly provided at both ends of the outer wall of the collection frame 61. A positioning sleeve 66 is fitted on the upper end of the positioning rod 65. The sleeve 66 and the processing plate 64 are fixedly connected. The shape of the placement groove 68 is adapted to the part to be processed. The lower end of the baffle 7 is in contact with the upper end of the base plate 1. The second ball screw sleeve 11 is movably inserted into the upper end of the connecting frame 8. The upper end of the connecting frame 8 is provided with a sliding groove that cooperates with the slider. The lower end of the electric telescopic rod 18 is hinged to the outer wall of the connecting frame 8. The extension end of the electric telescopic rod 18 is hinged to the outer wall of the nozzle 17. The front end of the nozzle 17 is hinged to the connecting frame 8. A PLC controller 19 is provided on one side of the base plate 1.

[0021] The parts to be processed are placed on the upper end of the placement slot 68. The first ball screw sleeve 5 is started by the PLC controller 19. The first ball screw sleeve 5 slides along the outer wall of the first ball screw 4, driving the collection frame 61 to move laterally along the upper end of the base plate 1. During this movement, the slider at the lower end of the collection frame 61 slides along the slide rod and slide rail 2, increasing the stability of the collection frame 61 during movement. By moving the collection frame 61, the drill bit 14 at the upper end of the connecting frame 8 can gradually process the parts placed in the placement slot 68. The second motor 9 is started, driving the second ball screw 10 to rotate, and the drill bit 14 follows. The second ball screw sleeve 11 moves longitudinally along the upper end of the connecting frame 8. When the drill bit 14 moves to the upper end of the part to be processed, the hydraulic rod 12 can be activated to extend, and the drill bit 14 is rotated by the rotary motor 13 to drill the workpiece below. During the processing, when it is necessary to cool the drill bit 14 and the workpiece, the water pump is activated, and the coolant in the liquid tank 15 enters the water pipe 16 through the water pump. The coolant enters the nozzle 17 through the water pipe 16 and is sprayed out. The electric telescopic rod 18 is activated to extend or retract. The angle of the electric telescopic rod 18 can be adjusted, so that it can be used in different directions. Coolant is sprayed, and during the spraying process, some coolant falls through the water tank 67 onto the upper part of the filter screen 63. The filter screen 63 filters the cooled coolant, which is then collected in the collection frame 61. After processing, the operator can lift the processing plate 64, causing the positioning sleeve 66 to slide upwards along the positioning rod 65, removing the processing plate 64 from the upper part of the collection frame 61. Then, the filter screen 63 is removed from the collection frame 61 for easy replacement or cleaning. The operator can then use a suction device to extract the collected coolant from the collection frame 61 for reuse. The coolant is injected into the liquid tank 15 for reuse, thereby reducing coolant waste and allowing the coolant to be used multiple times, reducing processing costs. The baffle 7 is set so that if any debris flies out during the machining of the workpiece by the drill bit 14, the baffle 7 is always located at the upper end of the slide rail 2 to block the slide rail 2, thereby preventing the debris from entering the slide rail 2 and adhering to the first ball screw 4. This prevents the debris from affecting the use of the first ball screw 4 and the first ball sleeve 5, and prevents the first ball screw 4 and the first ball sleeve 5 from getting stuck due to debris. This makes the movement of the collection frame 61 safer and increases the service life of the device.
