Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining center technology, and more specifically, to a spindle cooling device for a gantry machining center. Background Technology
[0002] A gantry machining center is a large machining center whose spindle Z-axis is perpendicular to the worktable. Its overall structure consists of a portal frame frame formed by two columns and a top beam, with a crossbeam in the middle. It is particularly suitable for machining large and complex-shaped workpieces. During machining, the spindle generates significant heat, requiring a cooling system. However, some gantry machining centers are open, and when cooling water is sprayed to cool the spindle, it splashes everywhere, affecting the operator's work and wasting cooling water. Therefore, designing a spindle cooling device for gantry machining centers is a problem we need to solve. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a spindle cooling device for a gantry machining center. By setting a shrink shield, the spindle is covered inside the shrink shield. When the spindle sprays coolant to cool down, the splashed water is confined inside the shrink shield, then flows downward and is recovered, thereby solving the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a spindle cooling device for a gantry machining center, comprising a main body, a spindle box on one side of the main body, an installation ring at the bottom of the spindle box, a magnet fixedly installed inside the installation ring, a shrink shield fixedly installed at the bottom of the installation ring, a rubber base fixedly installed at the bottom of the shrink shield, a support ring fixedly installed inside the rubber base, a connecting rod fixedly installed on the outer side of the rubber base, an adjusting screw fixedly installed at the top of the connecting rod, a limit sleeve fixedly installed on one side of the spindle box, and the adjusting screw slidably connected to the inner side of the limit sleeve.
[0005] In a preferred embodiment, the outer side of the adjusting screw is threaded with a threaded sleeve, and a connecting rope is fixedly installed at the top end of the adjusting screw.
[0006] In a preferred embodiment, a hanging ring is fixedly installed at the top end of the connecting rope, and a hook is fixedly installed on one side of the spindle box.
[0007] In a preferred embodiment, a liquid storage tank is fixedly installed on one side of the main body, and a filter plate is fixedly installed on the inner wall of the liquid storage tank.
[0008] In a preferred embodiment, a first infusion pipe is connected to one side of the liquid storage tank, and a water pump is connected to one end of the first infusion pipe.
[0009] In a preferred embodiment, a second infusion pipe is connected to the top of the water pump, and a fixing frame is fixedly installed on one side of the main shaft box, with the second infusion pipe fixedly installed inside the fixing frame.
[0010] In a preferred embodiment, one end of the second infusion tube is connected to a main shaft, and the bottom of the main shaft box is provided with a main shaft.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] 1. This utility model, by setting a shrinkable cover, allows for the fixation of the spindle box by placing the shrinkable cover on the outside during cooling. The magnet attracts the shrinkable cover, and the spindle is covered inside the shrinkable cover. When the spindle sprays coolant for cooling, the splashed water is confined inside the shrinkable cover and then flows downward, facilitating coolant recovery. The length of the shrinkable cover can be adjusted as needed, thereby improving ease of use and preventing excessive cooling water splashing that could affect the normal work of the staff.
[0013] 2. This utility model, by setting up a liquid storage tank and a filter plate, and by using a shrink shield to restrict the splashed coolant, allows the coolant to flow downwards onto the surface of the main body and flow into the liquid storage tank from the surface of the main body. The filter plate can filter out the iron filings generated, preventing them from mixing with the coolant, thereby enabling the coolant to be recycled and avoiding waste. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Refer to the instruction manual appendix Figure 1-3 ,like Figure 1 As shown, an embodiment of the present invention provides a spindle cooling device for a gantry machining center, comprising a main body 1, with a spindle housing 2 provided on one side of the main body 1, as shown in the figure. Figure 2 As shown, the bottom of the spindle box 2 is provided with a mounting ring 3, and a magnet 4 is fixedly installed inside the mounting ring 3. A shrink shield 5 is fixedly installed at the bottom of the mounting ring 3, as shown. Figure 3 As shown, a rubber base 6 is fixedly installed at the bottom of the shrink shield 5, and a support ring 7 is fixedly installed inside the rubber base 6. The support ring 7 shapes the rubber base 6, keeping it in a circular state. A connecting rod 8 is fixedly installed on the outside of the rubber base 6, and an adjusting screw 9 is fixedly installed at the top of the connecting rod 8. A limit sleeve 10 is fixedly installed on one side of the spindle box 2. Figure 2 As shown, the adjusting screw 9 is slidably connected to the inner side of the limiting sleeve 10, and the outer side of the adjusting screw 9 is threadedly connected to a threaded sleeve 11. A connecting rope 12 is fixedly installed at the top of the adjusting screw 9, and a hanging ring 13 is fixedly installed at the top of the connecting rope 12. Figure 1 As shown, a hook 14 is fixedly installed on one side of the spindle box 2.
[0020] It should be noted that, during the cooling of the spindle of the gantry machining center, the coolant in the reservoir 15 is drawn out through the first delivery pipe 17 by the water pump 18 and delivered to the spindle 21 through the second delivery pipe 19. The coolant is then sprayed onto the surface of the spindle 22 via the spindle 21, thus cooling the spindle 22. Simultaneously, while cooling the spindle 22, a shrink shield 5 is placed over the outside of the spindle 22, causing the magnet 4 to attract the spindle housing 2, thereby fixing the shrink shield 5 in place. A slit is provided on one side of the shrink shield 5, through which the second delivery pipe 19 can be placed. The shrink shield 5 covers the spindle 21 and 22 inside. When the spindle 21 sprays coolant to cool the spindle 22, the splashed water is confined inside the shrink shield 5 before flowing downwards. Furthermore, the shrink shield 5 is contractile; when the spindle 22 descends to process the workpiece, the rubber base 6 contacts the workpiece, causing the shrink shield 5 to contract. This allows the cutting tool to contact the workpiece for machining. When the shrink shield 5 retracts, the connecting rod 8 drives the adjusting screw 9 to slide upward inside the limiting sleeve 10. By rotating the threaded sleeve 11, the adjusting screw 9 rises, thereby controlling the maximum length of the shrink shield 5 in the stretched state. The length of the shrink shield 5 can be adjusted according to needs, thus avoiding the splashing of cooling water while accommodating the overall length of the spindle and cutting tool. This prevents the shrink shield 5 from being too long and affecting the machining of the workpiece. When it is necessary to retract the shrink shield 5 to change the cutting tool, the hanging ring 13 is pulled upward to hook the hook 14 on the outside, thereby retracting and fixing the shrink shield 5. At this time, the cutting tool mounted on the spindle can be changed, which improves the convenience of use and also achieves the purpose of intercepting splashed cooling water, preventing excessive cooling water from affecting the normal work of the operator.
[0021] Furthermore, such as Figure 1 As shown, a liquid storage tank 15 is fixedly installed on one side of the main body 1. A filter plate 16 is fixedly installed on the inner wall of the liquid storage tank 15. A first infusion pipe 17 is connected to one side of the liquid storage tank 15. A water pump 18 is connected to one end of the first infusion pipe 17. A second infusion pipe 19 is connected to the top of the water pump 18. A fixing bracket 20 is fixedly installed on one side of the main shaft box 2. The second infusion pipe 19 is fixedly installed inside the fixing bracket 20. Figure 3 As shown, one end of the second infusion tube 19 is connected to a main shaft 21, and the bottom of the main shaft box 2 is provided with a 22.
[0022] It should be noted that, in this process, the coolant is restricted by the shrink shield 5, allowing it to flow downwards onto the surface of the main body 1 and into the storage tank 15. The iron filings generated can be filtered by the filter plate 16 to prevent them from mixing with the coolant, thereby enabling the coolant to be recycled and avoiding waste.
