Description

Technical Field

[0001] This utility model relates to the technical field of vertical machining centers, specifically a waterproof structure for the base of a vertical machining center. Background Technology

[0002] Vertical machining centers are highly automated, multi-functional CNC machine tools equipped with tool magazines and automatic tool changers. During machining, cutting fluid is sprayed, so a waterproof mechanism is needed to block the splashed cutting fluid and achieve waterproofing.

[0003] In existing technologies, the waterproofing measures for vertical machining center bases are mostly simple, usually only achieving waterproofing and drainage by setting up a basic retaining edge or a simple drainage channel. In actual use, this type of structure has obvious defects. First, the sealing performance of the connection between the retaining edge and the base is insufficient, and liquid can easily seep from the gaps to the bottom of the base, causing corrosion of the bottom parts of the equipment and affecting the service life of the equipment. The drainage channel is mostly a flat-bottomed structure, which has low drainage efficiency and lacks an effective filtration device. Debris can easily enter the drainage channel with the liquid, causing blockage and reducing the drainage effect. It is difficult to meet the waterproofing requirements of machining centers. Therefore, the inventor has invented a waterproof structure for vertical machining center bases to solve the above problems. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a waterproof structure for the base of a vertical machining center to solve the technical problems of insufficient sealing performance and low drainage efficiency between the base and the edge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for a vertical machining center base, comprising a base, a guide groove at the top of the base, a filter device mounted within the guide groove, a baffle fixedly connected to the top edge of the base, an annular water-blocking edge fixedly connected at the connection between the base and the baffle, a groove for engaging with the annular water-blocking edge at the bottom of the baffle, a sloped surface on the side of the annular water-blocking edge facing the center of the base, a waterproof sealing plate fixedly connected to the top of the sloped surface of the annular water-blocking edge, a sealing ring fixedly connected to the side of the waterproof sealing plate facing the center of the base, and a waterproof groove for engaging with the waterproof sealing plate within the groove.

[0006] By adopting the above technical solution, and by setting a guide channel at the top of the base, coolant and waste liquid generated during processing can be effectively collected, preventing liquid from flowing freely. Simultaneously, the annular water-retaining edge at the connection between the base and the baffle, in conjunction with the groove, forms a multi-layered sealing structure with a waterproof sealing plate, sealing ring, and waterproof groove. This significantly improves the sealing performance of the connection between the base and the baffle, preventing liquid leakage from gaps. The sloping design of the annular water-retaining edge guides the liquid flow into the guide channel, further reducing the risk of edge leakage. The filter device can pre-intercept larger debris, preventing it from entering the guide channel and causing subsequent blockage. The overall structure improves waterproof performance from multiple aspects, including collection, sealing, and guidance, providing reliable protection for the machining center base.

[0007] Furthermore, the filtration device includes a baffle, multiple vertical filter screens, and a bottom filter screen. The bottom filter screen has a ring structure, the baffle is fixedly connected to both sides of the bottom filter screen, and the vertical filter screens are uniformly fixedly connected to the top of the bottom filter screen.

[0008] By adopting the above technical solution, the baffle can provide stable support for the bottom filter screen, ensuring that the bottom filter screen is not easily deformed when intercepting debris. Multiple vertical filter screens are evenly distributed on the bottom filter screen, which can intercept debris in the liquid from different angles, improving the filtration effect. At the same time, the bottom filter screen adopts a ring structure, which is adapted to the shape of the guide channel and can fully cover the filtration area of ​​the guide channel, preventing unfiltered liquid from directly entering the bottom of the guide channel. The bottom filter screen can also perform secondary filtration on the fine debris intercepted by the vertical filter screen, further reducing the probability of debris entering the drainage system, ensuring smooth drainage, and reducing drainage failure caused by blockage.

[0009] Furthermore, the bottom of the guide channel is a sloping structure, and a drain outlet is provided on the base. The drain outlet is connected to the guide channel and is located at the bottom of the slope of the guide channel.

[0010] By adopting the above technical solution, the slope structure at the bottom of the guide channel can guide the liquid to flow to the bottom of the slope using gravity, accelerate the liquid collection speed, improve drainage efficiency, and prevent the liquid from stagnating in the guide channel for a long time. At the same time, the drain outlet is set at the bottom of the slope of the guide channel, which can ensure that the collected liquid can be discharged quickly through the drain outlet, reduce the liquid residence time in the base, reduce the possibility of liquid seeping into the base, and form an efficient drainage path in conjunction with the guide channel, effectively preventing the problem of liquid accumulation caused by poor drainage and protecting the base and surrounding components from liquid corrosion.

[0011] Furthermore, the annular water-blocking edge has multiple threaded holes on the side facing away from the center of the base, and the bottom end of the baffle has a through hole that matches the threaded holes. The baffle is fixedly connected to the annular water-blocking edge by bolts.

[0012] By adopting the above technical solution, multiple threaded holes on the side of the annular water-retaining edge facing away from the center of the base are matched with through holes at the bottom of the baffle. The annular water-retaining edge and the baffle are fixedly connected by bolts, which can enhance the firmness of the connection between the two and prevent the connection from loosening due to vibration during equipment operation. At the same time, this bolt connection method is easy to install and disassemble. When the sealing components need maintenance or replacement, the baffle and the annular water-retaining edge can be quickly separated, reducing the difficulty of maintenance. Moreover, the bolt connection can ensure the tightness of the connection parts, and together with the sealing structure, it can further improve the waterproof effect and ensure the stability of the connection during long-term use.

[0013] Furthermore, a support rod is fixedly connected to the bottom end of the baffle, and the bottom end of the support rod is in contact with the bottom of the guide channel.

[0014] By adopting the above technical solution, the support rod at the bottom of the baffle can provide auxiliary support for the filter device, preventing it from tilting or sinking due to excessive debris when relying solely on the baffle support. This ensures the stability of the filter device within the guide channel. At the same time, the bottom of the support rod fits into the bottom of the guide channel, maintaining a reasonable gap between the filter device and the guide channel. This does not affect the flow of liquid within the guide channel, ensuring that the filtered liquid can flow smoothly to the drain outlet. This not only guarantees the structural stability of the filter device but also does not hinder the normal functioning of the drainage system.

[0015] Furthermore, the vertical filter screen is perpendicular to the horizontal plane, and the bottom filter screen is parallel to the bottom of the guide channel.

[0016] By adopting the above technical solution, the vertical filter screen is set perpendicular to the horizontal plane, which increases the contact area with the liquid, more effectively intercepts horizontally flowing debris, and improves filtration efficiency. At the same time, the bottom filter screen is parallel to the bottom of the guide channel, which can be adapted to the slope structure of the guide channel, ensuring that the bottom filter screen can fully cover the corresponding area at the bottom of the guide channel, fully filtering the liquid flowing to the bottom of the slope, preventing fine debris from passing through the gap between the bottom filter screen and the guide channel, further ensuring the filtration effect and reducing the risk of drainage system blockage.

[0017] Furthermore, the waterproof sealing plate is perpendicular to the horizontal plane, the sealing ring is a strip structure, and the sealing ring is bonded to the waterproof sealing plate with waterproof adhesive.

[0018] By adopting the above technical solution, the waterproof sealing plate is set perpendicular to the horizontal plane, which can form a vertical sealing fit with the waterproof groove at the bottom of the baffle, increasing the path length of liquid leakage and improving the sealing reliability. At the same time, the strip-shaped sealing ring is bonded to the waterproof sealing plate with waterproof adhesive, which can ensure that the sealing ring and the waterproof sealing plate fit tightly and avoid gaps. When the sealing ring and the waterproof groove are in contact, they can produce a good sealing effect, further blocking the liquid leakage channel. The multiple sealing design significantly improves the waterproof performance of the connection between the base and the baffle, ensuring the long-term stable operation of the equipment.

[0019] In summary, the present invention has the following main advantages: 1. This utility model, through the cooperation of the groove and the annular water-blocking edge, as well as the cooperation of the waterproof sealing plate and the waterproof groove, forms a labyrinth-type seal between the baffle and the annular water-blocking edge, effectively increasing the length of the leakage path. At the same time, the inclined design of the annular water-blocking edge further guides the liquid flow to the guide channel, greatly improving the waterproof performance at the connection between the baffle and the base. 2. This utility model uses the sloping structure at the bottom of the guide channel, combined with the drain outlet located at the bottom of the slope, to quickly guide the liquid to the drain outlet for discharge, reducing liquid accumulation on the base surface. At the same time, the filter device can intercept cutting debris, preventing it from entering the drainage channel and causing blockage, ensuring smooth drainage and reducing the risk of component corrosion caused by liquid accumulation.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In this embodiment: A waterproof structure for the base of a vertical machining center, such as Figure 1-6As shown, the structure includes a base 1, which serves as the main installation foundation for the entire waterproof structure, providing a stable assembly platform for subsequent components and ensuring the positional accuracy and operational reliability of each component after installation. A flow guide trough 2 is located at the top of the base 1. The flow guide trough 2 is an annular structure, arranged around the center of the base 1, fully covering the area where liquid may flow, facilitating rapid collection of coolant generated during processing. A filter device is installed inside the flow guide trough 2, stably installed to adapt to the size and shape of the flow guide trough 2, intercepting debris before the liquid enters the bottom of the flow guide trough 2, preventing obstruction of drainage. A baffle 3 is fixedly connected to the top edge of the base 1. The baffle 3 is an annular structure fixed around the top edge of the base 1, and its height is adapted to the protection requirements of the machining center, preventing liquid from splashing or overflowing to the outside of the base 1. An annular water-retaining edge 4 is fixedly connected at the connection between the base 1 and the baffle 3. The cross-section of the annular water-retaining edge 4 is a right-angled triangle. The bottom end of the annular water-retaining edge 4 is directly welded or integrally formed with the base 1. A recessed area is provided at the bottom end of the baffle 3 for cooperation with the annular water-retaining edge 4. The dimensions of groove 5 and recess 5 are precisely matched with the shape of the annular water-retaining edge 4, forming an embedded fit and increasing the path length for liquid leakage. The side of the annular water-retaining edge 4 facing the center of the base 1 is inclined, and the inclined design conforms to the liquid flow law, which can guide the liquid adhering to the surface of the annular water-retaining edge 4 into the guide channel 2. At the same time, the connection surface between the annular water-retaining edge 4 and the baffle 3 is also inclined, effectively preventing coolant from entering. A waterproof sealing plate 6 is fixedly connected to the top of the inclined surface of the annular water-retaining edge 4. The waterproof sealing plate 6 is set perpendicular to the horizontal plane and forms an integrated structure with the annular water-retaining edge 4, enhancing the structural strength of the sealing part and increasing the leakage path. A sealing ring 7 is fixedly connected to the side of the waterproof sealing plate 6 facing the center of the base 1. The sealing ring 7 is made of elastic material and can tightly fit the waterproof sealing plate 6 and subsequent mating structures, filling tiny gaps. A waterproof groove 8 is opened in the recess 5 to match the waterproof sealing plate 6. The depth and width of the waterproof groove 8 are precisely matched with the waterproof sealing plate 6 and the sealing ring 7 to form a multi-layer sealing interlocking structure, further improving the sealing effect.

[0024] See Figure 2 , Figure 3 , Figure 4 , Figure 5The filtration device includes a baffle 13, multiple vertical filter screens 15, and a bottom filter screen 14. The three are fixed in one piece to ensure that the components do not loosen or deform during the filtration process, thus ensuring filtration stability. The bottom filter screen 14 has a ring structure, which is perfectly matched with the ring layout of the guide channel 2, and can fully cover the cross-section of the guide channel 2 to avoid filtration blind spots. The baffle 13 is fixedly connected to both sides of the bottom filter screen 14. The baffle 13 is set vertically along the edge of the bottom filter screen 14, which can enhance the edge strength of the bottom filter screen 14 and guide the liquid to enter the filtration area smoothly. The vertical filter screens 15 are evenly fixedly connected to the top of the bottom filter screen 14. The vertical filter screens 15 are evenly distributed along the length of the bottom filter screen 14 to form a dense vertical filtration barrier, which can efficiently intercept debris of different particle sizes in the liquid.

[0025] See Figure 3 , Figure 4 , Figure 5 The bottom of the guide channel 2 is a sloping structure with a reasonable inclination angle, which can accelerate the flow of liquid with the help of gravity and prevent the liquid from stagnating in the channel. The base 1 is provided with a drain port 9 to facilitate the collection of coolant and prevent the coolant from stagnating on the base 1. The drain port 9 is connected to the guide channel 2, and the connection part adopts a smooth transition design to reduce the resistance of liquid flow. The drain port 9 is located at the bottom of the slope of the guide channel 2, which is the area where the liquid naturally collects, ensuring that the liquid in the guide channel 2 can be completely discharged.

[0026] See Figure 1 , Figure 5 , Figure 4 , Figure 6 The annular water-retaining edge 4 has multiple threaded holes 10 on the side facing away from the center of the base 1. The threaded holes 10 are evenly distributed along the circumference of the annular water-retaining edge 4 to ensure balanced connection force and improve assembly stability. The bottom end of the baffle 3 has through holes 11 that match the threaded holes 10. The diameter and number of through holes 11 are perfectly matched with the threaded holes 10, and their positions are precisely aligned to facilitate the quick insertion of bolts 12. The baffle 3 is fixedly connected to the annular water-retaining edge 4 by bolts 12. The bolt connection method has the characteristics of convenient disassembly and firm connection, and can resist vibration during equipment operation.

[0027] See Figure 2 , Figure 4 , Figure 5 A support rod 16 is fixedly connected to the bottom of the baffle 13. The support rod 16 is spaced along the length of the baffle 13. The length is adapted to the slope of the bottom of the guide channel 2 to ensure uniform support for the filter device. The bottom of the support rod 16 is in contact with the bottom of the guide channel 2 to increase the contact area and prevent the filter device from tilting or shifting in the guide channel 2, while not affecting the normal flow of liquid.

[0028] See Figure 2 , Figure 3 , Figure 4 , Figure 5 The vertical filter screen 15 is perpendicular to the horizontal plane. The vertically set vertical filter screen 15 can maximize the use of the filtration space, enhance the interception effect of debris in the horizontally flowing liquid, and reduce debris circling. The bottom filter screen 14 is parallel to the bottom of the guide channel 2. The parallel setting can keep the bottom filter screen 14 and the bottom of the guide channel 2 with a uniform gap, ensuring that the liquid passes through smoothly.

[0029] See Figure 4 , Figure 5 , Figure 6 The waterproof sealing plate 6 is perpendicular to the horizontal plane. The vertically set waterproof sealing plate 6 can form a vertical sealing fit with the waterproof groove 8, increasing the sealing contact area and improving sealing reliability. The sealing ring 7 is a strip structure. The strip structure can fully cover the sealing area along the length of the waterproof sealing plate 6, improving sealing performance. The sealing ring 7 is bonded to the waterproof sealing plate 6 with waterproof adhesive. The waterproof adhesive can enhance the connection between the sealing ring 7 and the waterproof sealing plate 6, prevent the sealing ring 7 from falling off due to equipment vibration, and further fill the tiny gaps between the two.

[0030] The implementation principle of this embodiment is as follows: First, the baffle 3 at the top edge of the base 1, together with the annular water-blocking edge 4 and the groove 5, achieves initial water blocking. The inclined surface of the annular water-blocking edge 4 guides the coolant and waste liquid generated during processing to converge into the guide groove 2 in the center of the base 1. At the same time, the waterproof sealing plate 6, the sealing ring 7, and the waterproof groove 8 form a multiple seal, preventing liquid from leaking from the connection gap between the baffle 3 and the base 1. Furthermore, the cooperation between the inclined surface of the annular water-blocking edge 4 and the groove 5 ensures that the connection between the baffle 3 and the base 1 on the side facing the center of the base 1 is inclined, preventing the coolant from easily entering the baffle under the influence of gravity. At the connection between plate 3 and base 1, the slope structure at the bottom of the guide channel 2 uses gravity to assist the liquid to flow to the drain outlet 9 at the bottom of the slope. During the process, the filter device in the guide channel 2 intercepts cutting debris in the liquid in layers through the synergistic action of the bottom filter screen 14, multiple vertical filters 15 and the bottom filter screen 14, avoiding blockage of the drainage channel. The annular water baffle 4 and the baffle plate 3 are fixedly connected by bolts 12, threaded holes 10 and through holes 11 to ensure assembly stability. The baffle 13 and the support rod 16 can stably support the bottom filter screen 14 in the guide channel 2, leaving a flow channel for the coolant and preventing liquid accumulation.
