Description

Technical Field

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

[0002] With the rapid development of the machinery manufacturing industry, gantry machining centers are widely used in the field of machining. Currently, to achieve automated machining, gantry machining centers use tool-changing robots for automatic tool changing. During workpiece machining, the gantry machining center needs to cool the workpiece surface to improve the quality of the machining process.

[0003] For example, patent CN115592464A discloses a spray cooling device and cooling method for a gantry machining center. The spray mechanism can adjust the angle of the atomizing nozzle. When motor B is started, motor B drives gear A to rotate. Gear B meshes with gear A and rotates together with gear A, so that the fixed claw drives the atomizing nozzle to rotate together, thereby adjusting the angle of the atomizing nozzle. It can spray cool the dead corners and dark corners where the workpiece is hidden, thereby improving the machining quality.

[0004] However, when a gantry machining center processes a workpiece, the main heat-generating area is the processing location of the workpiece. The aforementioned spray cooling device sprays the entire workpiece during processing, but cannot concentrate the cooling on the processing location, thus affecting the cooling effect of the processing area and consequently affecting the overall quality of the workpiece.

[0005] Therefore, this application provides a spray cooling device for gantry machining centers that moves along with the machining tool to cool the workpiece machining position to meet the requirements. Utility Model Content

[0017] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, by setting...

[0018] By setting up a spray mechanism, during the process of machining the workpiece by moving the lower cutting tool along with the slide, the atomizing nozzle that sprays water downwards will move together with the cutting tool. This allows the water mist sprayed from the atomizing nozzle to fall accurately onto the workpiece being machined, thereby providing precise and concentrated cooling to the workpiece machining area and ensuring the cooling effect during machining.

[0019] By setting up an auxiliary unit, when the slide moves along the outside of the mounting frame and drives the lower cutting tool to different processing positions, the fixed rod will move simultaneously, driving the belt to rotate. This causes the left pulley to rotate, which in turn drives the rotating rod to rotate, thereby driving the conveyor wheel to rotate. This conveys the water pipe between the conveyor wheel and the limit wheel, so that when the position of the atomizing nozzle moves, the water pipe will be conveyed and moved together by the conveyor wheel. This ensures that the length of the water pipe between the left connecting frame and the atomizing nozzle is the same as the distance between the left connecting frame and the atomizing nozzle, thus preventing excessively long water pipes from dragging in the main body of the gantry machining center and affecting the tool's processing of the workpiece.

[0020] By setting an adjustment mechanism, the mist outlet at the lower end of the rotating frame can be moved below the nozzle orifice of different diameters, thereby changing the amount of spray emitted by the atomizing nozzle. This allows for precise adjustment of the spray volume according to the temperature generated during workpiece processing, achieving efficient use of water resources and thus saving water.

[0030] like Figures 1 to 3As shown, an embodiment of this utility model provides a spray cooling device for a gantry machining center, including a gantry machining center body 1. A guide rail 2 is installed at the bottom of the gantry machining center body 1, and a worktable 3 is installed at the top of the guide rail 2. A mounting frame 4 is installed at the top of the gantry machining center body 1, and a slide ram 5 is installed at the outer end of the mounting frame 4.

The spray direction of the atomizing nozzle 602 is vertically downward. As the slide 5 moves and drives the lower cutting tool to process the workpiece, the atomizing nozzle 602 that sprays downward will move along with the cutting tool, so that the water mist sprayed by the atomizing nozzle 602 will fall accurately to the workpiece being processed, thereby providing precise and concentrated cooling to the workpiece processing position and ensuring the cooling effect during processing.

[0031] like Figure 4 and Figure 5 An auxiliary unit is provided at the lower end of the main body 1 of the gantry machining center. The auxiliary unit includes a right connecting frame 604 fixedly connected to the upper right side inside the main body 1 of the gantry machining center. A first round shaft 605 is fixedly connected to the lower inner side of the right connecting frame 604, and a right pulley 606 is connected to the lower inner side of the right connecting frame 604. A left connecting frame 607 is fixedly connected to the upper left side inside the main body 1 of the gantry machining center. A rotating rod 608 is connected to the lower inner side of the left connecting frame 607, and a left pulley 609 is connected to the lower inner side of the left connecting frame 607. The right pulley 606 and the left pulley are also connected. A first rotating hole is provided at the center of the interior of 609. First circular holes are provided at the front and rear ends below the left connecting frame 607. The outer side of the first circular shaft 605 is rotatably connected to the inner side of the first rotating hole inside the right pulley 606. The front and rear ends of the inner side of the right connecting frame 604 are slidably connected to the front and rear sides of the right pulley 606. The outer rear end of the rotating rod 608 is fixedly connected to the inner side of the first rotating hole inside the left pulley 609. The front and rear ends of the inner side of the left connecting frame 607 are slidably connected to the front and rear sides of the left pulley 609. The outer rear end of the rotating rod 608 is rotatably connected to the inner side of the first circular hole. Therefore, when the belt 614 rotates, the right pulley 606 and the left pulley 609 can rotate together, thereby causing the rotating rod 608 to rotate.

[0032] The main body 1 of the gantry machining center is fixedly connected to a front fixed frame 610 at the upper part of the interior, in front of the left connecting frame 607. The upper inner side of the front fixed frame 610 is fixedly connected to a second round shaft 611. The outer side of the second round shaft 611 is rotatably connected to a limit wheel 612. The lower inner side of the front fixed frame 610 is connected to a conveyor wheel 613. The front and rear ends of the front fixed frame 610 are provided with second round holes. The middle position of the conveyor wheel 613 is provided with a fixing hole. The outer front end of the rotating rod 608 is rotatably connected to the inner side of the second round hole. The outer front end of the rotating rod 608 is fixedly connected to the inner side of the fixing hole inside the conveyor wheel 613. The front and rear sides of the conveyor wheel 613 are slidably connected to the front and rear ends of the inner side of the front fixed frame 610. The limiting wheel 612 has a second rotating hole inside. The outer side of the second round shaft 611 is rotatably connected to the inner side of the second rotating hole. The front and rear sides of the limiting wheel 612 are slidably connected to the front and rear ends of the inner side of the front fixed frame 610. The outer sides of the limiting wheel 612 and the conveying wheel 613 are rollingly connected to the outer side of the water pipe 603. The outer ends of the right pulley 606 and the left pulley 609 are fitted with belts 614. A fixing rod 615 is fixedly connected to the rear side of the slide ram 5. The rear end of the fixing rod 615 is fixedly connected to the outer side of the belt 614. As the slide ram 5 moves along the outside of the mounting frame 4, driving the lower cutting tool to different processing positions, the fixed rod 615 moves simultaneously, causing the belt 614 to rotate. This causes the left pulley 609 to rotate, which in turn causes the rotating rod 608 to rotate, thereby driving the conveyor wheel 613 to rotate. This conveys the water pipe 603 between the conveyor wheel 613 and the limit wheel 612, so that when the position of the atomizing nozzle 602 moves, the water pipe 603 is conveyed and moved together by the conveyor wheel 613. This ensures that the length of the water pipe 603 between the left connecting frame 607 and the atomizing nozzle 602 is the same as the distance between the left connecting frame 607 and the atomizing nozzle 602, preventing the excessively long water pipe 603 from dragging within the main body 1 of the gantry machining center and affecting the tool's processing of the workpiece.

[0033] like Figure 6 and Figure 7The lower end of the atomizing nozzle 602 is provided with an adjustment mechanism, which includes a limiting ring 701 fixedly connected to the lower outer side of the atomizing nozzle 602. A circular frame 702 is connected to the outer side of the lower end of the atomizing nozzle 602. An annular groove is formed on the circumferential surface of the inner side of the circular frame 702. The circumferential surface of the inner side of the circular frame 702 is slidably connected to the lower outer side of the atomizing nozzle 602. The outer side of the limiting ring 701 is slidably connected to the outer side of the annular groove. The bottom inner side of the circular frame 702 is slidably connected to the lower side of the atomizing nozzle 602. The lower end of the atomizing nozzle 602 has nozzle orifices of different diameters, which are distributed in a series of equal arcs below the atomizing nozzle 602. The lower end of the circular frame 702 has a mist outlet with equal arcs. By rotating the circular frame 702, the mist outlet at its lower end is moved below the nozzle orifices of different diameters, which changes the amount of spray emitted by the atomizing nozzle 602. Thus, the spray volume can be precisely adjusted according to the temperature generated during workpiece processing, achieving efficient use of water resources and thus saving water.

[0034] The working principle of the technical solution provided by this utility model is as follows: When using the main body 1 of the gantry machining center to process a workpiece, the workpiece to be processed is installed above the worktable 3, and then the main body 1 of the gantry machining center is opened to drive the worktable 3 and the slide ram 5 to move, so that the workpiece is processed during the relative movement of the tool and the workpiece. At the same time, the water supply device connected to the water pipe 603 is started, so that the atomizing nozzle 602 sprays water mist downward to the processing area of ​​the tool on the workpiece to cool the workpiece during processing.

[0035] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model.
