Description

Technical Field

[0001] This utility model relates to the technical field of protective door devices, specifically a protective door structure for CNC machining centers to prevent debris from splashing. Background Technology

[0002] During metal cutting and other machining processes, CNC machining centers inevitably generate a large amount of high-speed flying metal debris, a common technical challenge in the industry. This high-speed debris not only directly threatens the personal safety of operators but also easily adheres to the surfaces of precision components such as guide rails and lead screws, causing wear, reduced precision, and ultimately equipment failure, significantly increasing maintenance costs. Simultaneously, scattered debris contaminates the machining environment, increasing the workload and difficulty of subsequent cleaning. While existing CNC machining centers are equipped with protective doors and debris collection structures to address these issues, several shortcomings remain. Regarding protection, existing protective doors often employ simple sliding or flipping structures, resulting in poor opening and closing stability and a lack of effective sealing and cushioning designs. This not only leads to jamming during opening and closing and severe wear after prolonged use but also fails to completely prevent fine debris from splashing out from gaps, resulting in inadequate protection. Furthermore, some protective doors have unreasonable structural designs with limited opening ranges, causing inconvenience for workpiece loading / unloading and routine equipment maintenance. Regarding debris collection, existing collection devices are mostly fixed cavities or simple pull-out structures. These either struggle to precisely align with the machining area, leading to incomplete debris collection and easy debris accumulation, or the pull-out structure lacks smoothness, making cleaning laborious and cumbersome. These methods fail to efficiently collect and recycle debris, and cannot fundamentally solve the series of problems caused by debris. Therefore, developing a matching structure with good protective sealing, stable and convenient opening and closing, and efficient and easy-to-clean debris collection has become a key requirement for improving the safety, stability, and ease of use of CNC machining centers. Summary of the Invention

[0003] The purpose of this invention is to provide a protective door structure for CNC machining centers to prevent chip splashing, which solves the problems of poor sealing effect, unstable opening and closing, easy wear, inconvenient operation and maintenance, incomplete chip collection, and cumbersome cleaning of existing CNC machining center protective doors.

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.

[0018] Please see Figures 1-4 As shown, this utility model is a protective door structure for preventing chip splashing in a CNC machining center, including a protective door assembly 2, which is located on top of the main body assembly 1; a lathe assembly 4 is provided inside the protective door assembly 2; and a chip collection assembly 3 is provided below the lathe assembly 4. The protective door assembly 2 includes a protective door 201. The upper and lower ends of the protective door 201 are respectively provided with guide rails 203. A slide rail 202 is located inside the protective cover 106, and the slide rail 202 slides in cooperation with the guide rails 203. A transparent observation window 204 is provided in the middle of the protective door 201, and an observation window sealing strip 205 is provided around the transparent observation window 204. A hydraulic rod fixing block 206 is provided at the bottom of the outer side of the protective door 201. A hydraulic pump 207 is located on the outer side of the protective cover 106. The output end of the hydraulic pump 207 is connected to a hydraulic rod 208, and the other end of the hydraulic rod 208 is connected to the hydraulic rod fixing block 206. A buffer spring 209 is sleeved on the hydraulic rod 208 to absorb the impact force during the opening process through elastic deformation.

[0019] There are two protective doors 201, symmetrically arranged on both sides of the protective cover 106. Each protective door 201 is slidably connected to the slide rail 202 through the corresponding guide rail 203, so that the hydraulic energy is converted into mechanical energy to drive the hydraulic rod 208 to extend and retract.

[0020] The main component 1 includes a lathe base 101. The bottom of the lathe base 101 is provided with several foot pads 102. One end of the lathe base 101 is provided with a spindle control box 103. The outside of the spindle control box 103 is provided with a control switch 104 and a heat dissipation grille 105. By increasing the heat dissipation area and accelerating air circulation, the internal electrical control components are continuously cooled throughout the operation of the equipment, ensuring the stable operation of the electrical control system.

[0021] The top of the lathe base 101 is provided with a protective cover 106; one side of the protective cover 106 is provided with a removable side plate 107, providing ample space for maintenance operations; the interior of the protective cover 106 houses the lathe assembly 4.

[0022] The chip collection component 3 includes a chip discharge drawer 301, which is located inside the lathe base 101. Drawer slides 302 are provided on both sides of the chip discharge drawer 301. Drawer handles 303 are provided on the outside of the chip discharge drawer 301 for chip cleaning, reducing maintenance difficulty.

[0023] The chip removal drawer 301 is located inside the lathe base 101, directly below the lathe assembly 4.

[0024] The lathe assembly 4 includes a lathe bed 401, which has multiple chip channels 402 along the axial direction; multiple threaded drive rods 403 are provided along the axial direction on the outer periphery of the lathe bed 401; a radial tool table 404 is threadedly connected to the threaded drive rods 403; a radial cutter head 405 is provided above the radial tool table 404; an axial tool table 406 is provided at one end of the lathe bed 401 away from the spindle control box 103; an axial cutter head 407 is provided above the axial tool table 406, thereby realizing multi-directional and high-precision machining of the workpiece.

[0025] Before starting the equipment, the hydraulic pump 207 is operated by the control switch 104 of the spindle control box 103. The hydraulic pump 207 converts hydraulic energy into mechanical energy to drive the hydraulic rod 208 to extend and retract. With the smooth and strong driving force of hydraulic transmission, the protective doors 201 on both sides are opened through the sliding cooperation of the guide rail 203 and the slide rail 202. The buffer spring 209 sleeved on the hydraulic rod 208 absorbs the impact force during the opening process through elastic deformation, reducing the collision wear between the protective door and the slide rail. After the workpiece to be processed is installed on the lathe assembly 4, the hydraulic pump 207 is operated in reverse to close the protective door 201. The observation window sealing strip 205 fills the gap between the protective door and the protective cover through its own elastic compression, ensuring the sealing after closure and blocking the high-speed flying debris during processing from the source. The operator can monitor the processing status in real time through the transparent observation window 204 to facilitate the timely detection of processing abnormalities. During the machining process, the spindle control box 103, as the core control unit, outputs control signals to drive the threaded transmission rod 403 to rotate. Utilizing the precise transmission characteristics of the threaded transmission, it drives the radial tool table 404 and the radial tool head 405 to move precisely along the axial direction. At the same time, the axial tool head 407 on the axial tool table 406 works in coordination to achieve multi-directional, high-precision machining of the workpiece. Under the action of gravity, some of the chips generated during machining fall directionally through the chip channel 402 preset in the lathe bed 401 and finally fall into the chip drawer 301 located directly below the lathe assembly 4, completing the initial collection of chips. After processing, the protective door 201 is opened again to remove the workpiece. Subsequently, the chip removal drawer 301 can be easily pulled out for chip cleaning by using the drawer handle 303 in conjunction with the sliding guide of the drawer slide rail 302, reducing maintenance difficulty. If deep maintenance is required inside the equipment, the detachable side plate 107 on one side of the protective cover 106 can be removed to provide sufficient space for maintenance operations. The heat dissipation grille 105 on the outside of the spindle control box 103 continuously dissipates heat for the internal electrical control components throughout the entire operation of the equipment by increasing the heat dissipation area and accelerating air circulation, ensuring the stable operation of the electrical control system.
