Description

Technical Field

[0001] This utility model relates to the technical field of vertical machining centers, and in particular to a vertical machining center with a protective mechanism. Background Technology

[0002] Vertical machining centers are highly automated CNC machining equipment widely used in the machinery manufacturing industry. Their core features include a vertically positioned spindle, a workpiece fixed on a worktable, and a CNC system controlling the tool movement along the X, Y, and Z axes to perform various machining operations such as milling, drilling, boring, and tapping. They typically consist of a bed, column, worktable, spindle box, and feed mechanism. The bed, as the basic support, must possess good rigidity and stability to reduce machining vibration.

[0003] Existing protective solutions for vertical machining centers include: Solution 1: Fixed metal protective cover. This involves bolting on an integral metal shell. Its advantages are high structural strength, but its disadvantages include obstructing workpiece loading and unloading and the observation window being easily contaminated. Solution 2: Flexible roller shutter protection. This uses PVC fabric curtains with sliding guide rails. Its advantages are small space occupation, but its disadvantages are poor high-temperature resistance. Solution 3: Pneumatic transparent protective door. This uses a pneumatically driven polycarbonate door. Its advantages are good visibility, but its disadvantages are that the system requires a continuous air supply.

[0004] However, in some existing vertical machining centers, fixed protective covers result in poor equipment accessibility, flexible protection is at risk of aging and cracking, and transparent protective doors are prone to stress cracks under the impact of high-pressure coolant. Therefore, a vertical machining center with a protective mechanism is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vertical machining center with a protective mechanism, aiming to improve the problem that the protective mechanism of some existing vertical machining centers is inconvenient to use and has poor protective effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vertical machining center with a protective mechanism, comprising an outer frame, a protective mechanism provided on the front side of the outer frame, a spraying mechanism provided on the top of the outer frame, a cutting module installed on the top of the outer frame, and a collection mechanism provided inside the outer frame;

[0007] The protective mechanism includes two sliding doors, which are slidably connected to the outside of the outer frame. A power assembly is installed on the rear side of each sliding door, and a sliding frame is fixedly connected to the rear side of each power assembly. A fixed shaft is fixedly connected inside each sliding frame, and a protective plate is rotatably connected to the outside of each fixed shaft. Two movable balls are hinged to the rear side of each protective plate, and sliding rods are fixedly connected to the rear side of each movable ball. Fixed rings are fixedly connected to the outside of each sliding rod, and springs are sleeved on the outside of each sliding rod. A limiting plate is fixedly connected to the front side of each sliding rod, and two guide rods are fixedly connected to the bottom of each sliding frame.

[0008] The above technical solution utilizes a frame as the main body, with a protective mechanism at the front, a spraying mechanism and a cutting module at the top, and an internal collection mechanism. Through the coordinated operation of these mechanisms, the system achieves functions such as workpiece protection, cutting, coolant circulation, and debris collection, providing comprehensive protection for machining.

[0009] As a further description of the above technical solution:

[0010] Both of the power components include two fixed frames, the front sides of which are fixedly connected to the rear sides of the two sliding doors respectively. A rotating rod is rotatably connected inside each of the two fixed frames, and a second fixed frame is rotatably connected to the top of each of the two rotating rods.

[0011] The above technical solution involves the fixed frame one sliding with the sliding door, which drives the rotating rod to rotate, thereby driving the fixed frame two to move, converting the linear motion of the sliding door into the vertical motion of the sliding frame, thus realizing the raising and lowering of the guard plate. This not only facilitates operation but also provides protection during processing.

[0012] As a further description of the above technical solution:

[0013] The spraying mechanism includes a suction pump, the bottom of which is mounted on the top of the outer frame. The output end of the suction pump is fixedly connected to a water inlet pipe, and the input end of the suction pump is fixedly connected to a water suction pipe. A support frame is fixedly connected inside the outer frame, and a collection box is fixedly connected inside the support frame. A filter plate is fixedly connected to the top of the collection box, and a water tank is fixedly connected to the top of the outer frame. A spraying module is installed on the top side inside the outer frame.

[0014] The above technical solution involves a suction pump drawing coolant from a collection tank via a suction pipe, injecting it into a water tank through an inlet pipe, filtering cutting waste fluid through a filter plate and flowing into the collection tank, and then spraying the coolant from the tank onto the workpiece using a spraying module. This achieves the recycling of coolant and saves resources.

[0015] As a further description of the above technical solution:

[0016] The collection mechanism includes a cylinder, with the right side of the cylinder installed on the inner left side of the outer frame. A push rod is fixedly connected to the drive end of the cylinder, and a scraper is fixedly connected to the left side of the push rod. A collection box is fixedly connected to the inner left side of the outer frame.

[0017] The above technical solution involves a cylinder driving a push rod, which in turn moves the scraper horizontally, pushing debris from the surface of the filter plate into the collection box, ensuring the filter plate is clean and maintaining the filtration effect.

[0018] As a further description of the above technical solution:

[0019] The rear side of the second fixed frame is fixedly connected to the front side of the sliding frame, and the exterior of the first fixed frame is slidably connected to the interior of the outer frame.

[0020] The above technical solution allows the fixed frame to slide within the outer frame, ensuring the stability and continuity of the power component's movement. This enables the sliding frame to precisely drive the guard plate up and down, enhancing the reliability of the protective mechanism.

[0021] As a further description of the above technical solution:

[0022] The outer side of the slide rod is slidably connected to the inside of the slide frame, and the rear side of the slide frame is slidably connected to the front side of the support frame.

[0023] The above technical solution involves the sliding rod sliding within the sliding frame, which in turn slides in front of the support frame. This provides guidance and support for the rotation of the guard plate when it is impacted. In conjunction with the spring, it achieves buffering and protection against splashes, while ensuring the overall smooth movement of the protective mechanism.

[0024] As a further description of the above technical solution:

[0025] One end of the spring is fixedly connected to the front side of the fixed ring, and the other end of the spring is fixedly connected to the front side of the sliding frame.

[0026] The above technical solution allows the spring to absorb the impact force when the guard plate is impacted, and the guard plate is reset by the elastic force after the impact disappears, effectively improving the protective performance of the protective mechanism against flying objects.

[0027] As a further description of the above technical solution:

[0028] The water inlet pipe is externally fixedly connected to the inside of the water tank, and the water pumping pipe is externally fixedly connected to the inside of the collection tank.

[0029] The above technical solution connects the suction pump and the collection tank through a water pipe, clearly defining the coolant circulation path and ensuring stable circulation of coolant between the water tank, collection tank, and suction pump, thereby achieving efficient recycling of coolant.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, when the sliding door is pulled, it moves inside the outer frame that is slidably connected to the outside, causing the fixed frame one that is fixedly connected to the rear to move closer together, causing the rotating rod to rotate, which in turn causes the fixed frame two to move, causing the sliding frame to rise. The guide rod at the bottom of the sliding frame slides inside the outer frame to ensure stable movement and realize the raising of the guard plate. When debris is splashed during processing, the guard plate is impacted and rotates around a fixed axis. The sliding rod slides inside the sliding frame through the movable ball hinge, compressing the spring. With the help of the spring force, the debris is effectively blocked, ensuring the safety of the operator. Moreover, the operation is simple, and the switching of the protective state can be completed without complicated operations.

[0032] 2. In this utility model, during the processing, the spraying module evenly sprays the coolant in the water tank onto the workpiece through a high-pressure atomizing nozzle. The waste liquid generated during cutting is filtered by the filter plate at the top of the collection tank to achieve solid-liquid separation. The filtered coolant flows into the collection tank. The suction pump, as the power source, draws the coolant out of the collection tank through the water pipe and re-injects it into the water tank for recycling through the water inlet pipe. At the same time, when there are residual debris on the surface of the filter plate, the cylinder drives the push rod to drive the scraper to push the debris to the collection box, ensuring the filter plate is clean, maintaining the filtration effect, reducing coolant waste, lowering production costs, and conforming to the concept of energy conservation and environmental protection.

[0041] 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.

[0042] Reference Figures 1 to 3 This utility model provides an embodiment of a vertical machining center with a protective mechanism, comprising an outer frame 1, which serves as the main frame of the vertical machining center. A protective mechanism 2 is provided on the front side of the outer frame 1, and a spraying mechanism 3 is provided on the top of the outer frame 1. A cutting module 4 is installed on the top of the outer frame 1 and is the core component for cutting operations in the vertical machining center. The cutting module 4 mainly consists of a spindle, a tool mounting base, a drive motor, and a transmission system. A collection mechanism 5 is provided inside the outer frame 1. The protective mechanism 2 includes two sliding doors 21, which are slidably connected to the outside of the outer frame 1. A power assembly 22 is provided on the rear side of each of the two sliding doors 21. Both power components 22 include two fixed frames 221. The fixed frames 221 move with the sliding door 21. The front sides of the two fixed frames 221 are fixedly connected to the rear sides of the two sliding doors 21 respectively. The outside of the fixed frames 221 is slidably connected to the inside of the outer frame 1. The inside of the two fixed frames 221 is rotatably connected to a rotating rod 222. The top of the two rotating rods 222 is rotatably connected to a fixed frame 223. When the sliding door 21 slides, the fixed frame 223 can be moved according to the displacement of the fixed frame 221, so as to convert the linear motion of the sliding door 21 into the vertical motion of the sliding frame 23. The rear side of the fixed frame 223 is fixedly connected to the front side of the sliding frame 23.

[0043] Specifically, the sliding door 21 slides inside the outer frame 1, and the fixed frame 221 on the rear side moves accordingly, driving the rotating rod 222 to rotate, which in turn drives the fixed frame 223 to move, converting the linear motion of the sliding door 21 into the vertical motion of the sliding frame 23, thereby realizing the lifting and lowering of the guard plate 25. This movement process not only facilitates the operator to clamp the workpiece, but also the raised guard plate 25 can effectively block flying debris during processing, providing reliable protection for the processing process and ensuring that the processing is carried out safely and orderly.

[0044] Reference Figures 3 to 5 Each of the two power components 22 has a sliding frame 23 fixedly connected to its rear side. A fixed shaft 24 is fixedly connected inside each of the two sliding frames 23, allowing the guard plate 25 to rotate flexibly around it. The guard plate 25 is rotatably connected to the outside of each of the two fixed shafts 24, effectively blocking debris splashing during processing. Two movable balls 26 are hinged to the rear of each of the two guard plates 25, allowing for flexible rotation at multiple angles as the guard plate 25 rotates. Sliding rods 27 are fixedly connected to the rear of each of the movable balls 26, shifting with the rotation of the guard plate 25. The sliding rods 27 are slidably connected to the inside of the sliding frame 23. Fixed rings 28 are fixedly connected to the outside of each of the sliding rods 27, providing a stable support point for the spring 29 and ensuring its compression and reset effects. Both slide rods 27 are fitted with springs 29. One end of the spring 29 is fixedly connected to the front side of the fixed ring 28, and the other end of the spring 29 is fixedly connected to the front side of the slide frame 23. When the guard plate 25 is impacted, it can quickly compress and absorb the impact force. When the impact force disappears, the guard plate 25 is reset by its own elasticity, thus achieving effective protection against splashes. Both slide rods 27 are fixedly connected to the front side of the two slide rods 27. The function of the limiting plate 210 is to limit the sliding stroke of the slide rod 27 inside the slide frame 23 and prevent the slide rod 27 from sliding out of the slide frame 23. Both slide frames 23 are fixedly connected to the bottom of the two slide frames 23. The guide rods 211 play a stable guiding role when the slide frame 23 moves with the sliding door 21, ensuring that the slide frame 23 rises and falls vertically, and improving the movement accuracy and stability of the protective mechanism 2.

[0045] Specifically, the sliding door 21 moves up and down accordingly. The fixed shaft 24 inside the sliding frame 23 provides a pivot point for the guard plate 25, allowing it to rotate flexibly to block processing debris. When the guard plate 25 is impacted and rotates, the movable ball 26 hinged at the rear drives the sliding rod 27 to slide inside the sliding frame 23. The fixed ring 28 provides support for the spring 29, causing the spring 29 to compress and absorb the impact force. After the impact disappears, the guard plate 25 is reset by means of the elasticity, achieving efficient protection.

[0046] Reference Figure 1 , Figure 2 and Figure 6The spraying mechanism 3 includes a suction pump 31, the bottom of which is mounted on the top of the outer frame 1. The suction pump 31 serves as the power source for coolant circulation. An inlet pipe 32 is fixedly connected to the output end of the suction pump 31, and a suction pipe 33 is fixedly connected to the input end. The suction pipe 33 effectively draws coolant from the collection tank 34. A support frame 36 is fixedly connected inside the outer frame 1. The rear side of the sliding frame 23 is slidably connected to the front side of the support frame 36. The support frame 36 provides stable support and guidance for the sliding frame 23 and also serves as a support for the collection tank 34. 4. An installation space is provided. A collection box 34 is fixedly connected inside the support frame 36. The external of the water pump pipe 33 is fixedly connected inside the collection box 34. The collection box 34 can hold the filtered coolant. A filter plate 35 is fixedly connected to the top of the collection box 34. The filter plate 35 can effectively filter the waste liquid generated by cutting and achieve solid-liquid separation. A water tank 37 is fixedly connected to the top of the outer frame 1. The external of the water inlet pipe 32 is fixedly connected inside the water tank 37. A spraying module 38 is installed on the top side inside the outer frame 1. The spraying module 38 consists of multiple nozzles and pipes. The nozzles are high-pressure atomizing nozzles, which can evenly spray the coolant in the water tank 37 onto the workpiece to achieve cooling and lubrication of the workpiece.

[0047] Specifically, the suction pump 31 is installed on the top of the outer frame 1 as a power source for coolant circulation. Its input end is connected to the collection tank 34 located in the support frame 36 through the water pumping pipe 33. It can effectively extract the coolant filtered by the filter plate 35 in the collection tank 34. The filter plate 35 is fixed on the top of the collection tank 34 and is responsible for solid-liquid separation of the waste liquid generated by cutting.

[0048] Reference Figure 1 , Figure 2 and Figure 6 The collection mechanism 5 includes a cylinder 51. The right side of the cylinder 51 is installed inside the left side of the outer frame 1. The drive end of the cylinder 51 is fixedly connected to a push rod 52. The cylinder 51 can provide sufficient thrust to drive the push rod 52 and the scraper 53 to move in the horizontal direction. The left side of the push rod 52 is fixedly connected to the scraper 53. The scraper 53 can closely adhere to the surface of the filter plate 35, effectively scraping up the debris and pushing it into the collection box 54. The collection box 54 is fixedly connected inside the left side of the outer frame 1. The collection box 54 can hold a certain amount of debris.

[0049] Specifically, during operation, cylinder 51 provides thrust, which drives push rod 52 and scraper 53 fixed thereto to move horizontally. Since scraper 53 is in close contact with the surface of filter plate 35, it can scrape up the debris remaining on filter plate 35 during the movement and push it to the collection box 54 on the left side inside the outer frame 1 for collection.

[0050] Working principle: When using this vertical machining center, after placing the workpiece on top of the filter plate 35, the sliding door 21 can be slid inside the outer frame 1 by pulling the sliding door 21. At this time, the two fixed frames 221 will move closer to each other, causing the rotating rod 222 to rotate, which in turn causes the fixed frame 223 to move, which in turn causes the sliding frame 23 to move. At this time, the guide rod 211 will slide inside the outer frame 1, and the sliding frame 23 will rise as the sliding door 21 closes. At this time, the sliding frame 23 and the guard plate 25 can protect the machining process. When debris is splashed, the guard plate 25 will be impacted, causing the guard plate 25 to rotate around the fixed axis 24. The sliding rod 27 can slide inside the sliding frame 23 by means of the hinge of the movable ball 26. At this time, the spring 29 will be compressed, and the elastic force of the spring 29 can protect the splashed material.

[0051] During the processing, the workpiece can be cut by the cutting module 4, and the coolant in the water tank 37 can be sprayed onto the workpiece by the spraying module 38. The waste liquid generated by cutting will be filtered by the filter plate 35 to achieve solid-liquid separation. The filtered coolant enters the collection tank 34 and can then be recovered by the suction pump 31 through the water pipe 33 and reinjected into the water tank 37 through the water inlet pipe 32 for recycling. In addition, when it is necessary to remove the residual debris on the surface of the filter plate 35, the cylinder 51 can drive the push rod 52 and the scraper 53 to move, and the scraper 53 can push the debris into the collection box 54 for collection, ensuring the cleanliness and flatness of the surface of the filter plate 35, and preparing it for the next processing.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
