Description

Technical Field

[0001] This utility model relates to the field of CNC machining center protection technology, and in particular to a movable CNC machining center protective cover structure. Background Technology

[0002] Machining centers evolved from CNC milling machines. The biggest difference between them lies in their ability to automatically change cutting tools. By installing different tools in the tool magazine, the automatic tool changer can change the cutting tools on the spindle during a single setup, enabling multiple machining functions. A CNC machining center is a high-efficiency automated machine tool composed of mechanical equipment and a CNC system, suitable for machining complex parts. CNC machining centers are among the world's most produced and widely used CNC machine tools. They possess strong comprehensive machining capabilities, completing a significant amount of machining in a single setup with high precision. For batches of workpieces with moderate machining difficulty, their efficiency is 5-10 times that of ordinary equipment. In particular, they can perform many machining operations that ordinary equipment cannot, making them especially suitable for single-piece machining or small-batch, multi-variety production with complex shapes and high precision requirements. They integrate milling, boring, drilling, tapping, and thread cutting functions into a single machine, providing multiple machining processes. Machining centers are classified according to the spatial position of the spindle during machining: horizontal and vertical machining centers. Machining centers can be classified by their application: boring and milling machining centers, and multi-function machining centers. They can also be classified by special functions: single-table, double-table, and multi-table machining centers. Other types include single-axis, double-axis, and three-axis machining centers, as well as those with interchangeable spindle heads. Based on guideways, they can be classified as linear guide machining centers, hardened guide machining centers, etc. Protective covers utilize slideways, hinges, or electric drive mechanisms to achieve translation, rotation, or extension, precisely covering the machining area of ​​workpieces of different sizes.

[0003] However, existing protective covers have low compatibility during installation. When clamping different types of guide rails, different clamping methods cannot be selected. For different types of guide rails such as rectangular and circular ones, the clamping method cannot be switched. This leads to frequent modifications during installation, which is time-consuming. The clamping is unreliable and easily loosens or damages the guide rail. Maintenance requires tools throughout the process and is inconvenient. Furthermore, the protection may fail due to displacement. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please refer to Figure 1-6As shown; this utility model provides a technical solution for a movable CNC machining center protective cover structure: a movable CNC machining center protective cover structure includes a protective cover body 1, the protective cover body 1 is composed of multiple stepped protective covers 10, the multiple protective covers 10 slide and cooperate with each other to achieve a telescopic function; both sides of the protective cover body 1 are provided with mounting structures 2, the mounting structures 2 are provided with spacing adjustment structures 3, there are two spacing adjustment structures 3, the two spacing adjustment structures 3 are symmetrically arranged on both sides of the mounting structure 2; each spacing adjustment structure 3 is provided with a fixing clamping structure 4.

[0024] Multiple stepped protective covers 10 slide and cooperate with each other, and can be used in conjunction with a mobile CNC machining center during use;

[0025] During the installation of the protective cover body 1, different clamping methods can be selected according to the type of guide rail on the movable CNC machining center, such as square guide rail or round guide rail. This allows for precise adaptation, improved installation efficiency, reliable clamping, enhanced stability, convenient maintenance, reduced costs, upgraded protection, and guaranteed safety.

[0026] In this embodiment, refer to Figure 3 As shown, the mounting structure 2 includes a long mounting base 21, a short mounting base 22, and a telescopic rod 23. The long mounting base 21 is located on one side of the protective cover 10, the short mounting base 22 is located on the other side of the protective cover 10, and the telescopic rod 23 is mounted on the short mounting base 22. The telescopic rod 23 and the long mounting base 21 slide together to achieve telescopic adjustment.

[0027] The telescopic rod 23 can slide and extend within the long mounting base 21, so that the protective cover body 1 can be adapted for use regardless of the length of the protective area selected or the protective area adjusted according to the protection needs.

[0028] In this embodiment, each of the spacing adjustment structures 3 includes an adjustment frame 31, a bidirectional adjustment screw 32, and two adjustment blocks 33. The adjustment frame 31 is installed at the bottom of the long mounting base 21 or the short mounting base 22. The bidirectional adjustment screw 32 is rotatably connected to the adjustment frame 31. A turntable 34 is provided at the end of the bidirectional adjustment screw 32. The two adjustment blocks 33 are threadedly connected to the bidirectional adjustment screw 32, and the two adjustment blocks 33 are slidably engaged with the adjustment frame 31.

[0029] During use, the distance between the two adjusting blocks 33 can be adjusted according to the length of the guide rail. At this time, the turntable 34 can be rotated to drive the adjusting double-acting screw 32 to rotate on the adjusting frame 31, thereby moving the positions of the two adjusting blocks 33 away from or closer to each other, adjusting the positional distance between the two adjusting blocks 33. When installing the protective cover body 1, the two adjusting blocks 33 can be adjusted according to the length of the guide rail and the installation requirements.

[0030] In this embodiment, refer to Figure 4 As shown, each of the fixed clamping structures 4 includes a fixed frame 41, two sliders 42, and two sliding rods 43. The fixed frame 41 is located at the bottom of the adjusting block 33. The two sliding rods 43 are symmetrically arranged inside the fixed frame 41. The sliders 42 are slidably connected to the two sliding rods 43. The fixed frame 41 is provided with a clamping screw 44, which is rotatably connected to the sliders 42. The clamping screw 44 is provided with a handle 45. Each slider 42 is provided with a mounting groove, and a detachable clamping component is provided in the mounting groove. The clamping component is disassembled and installed by bolts 6. When facing different types of guide rails, the clamping component can be quickly replaced and installed.

[0031] When the protective cover body 1 is installed, rotating the handle 45 will drive the two clamping screws 44 to rotate on the fixed frame 41, thereby driving the two sliders 42 to move closer to each other on the two slide rods 43 respectively. When the two sliders 42 move closer to each other, the two clamping parts will move closer to each other, fixing the position of the protective cover body 1 on the guide rail to be installed, thereby realizing the installation and fixation of the protective cover body 1.

[0032] Example 1 of the clamping component;

[0033] In this embodiment, refer to Figure 5 As shown, the clamping component includes two first clamping blocks 46. The first clamping blocks 46 are connected to the mounting groove by two bolts 6. The first clamping blocks 46 are flat and are provided with flat anti-slip pads 47. The flat anti-slip pads 47 ensure that the square guide rail will not slip or be damaged when clamping it.

[0034] When installing the protective cover body 1 onto the square guide rail, the first clamping blocks 46 on the two planes clamp and fix the square guide rail close to each other, ensuring a tight fit between the two planes of the guide rail and conforming to its geometric characteristics, achieving gapless fixation. This tight fit effectively resists vibration and impact during processing, preventing the protective cover 10 from shifting or loosening, and ensuring the stability of the protective effect. The close clamping method ensures uniform force on the guide rail, avoiding localized stress concentration. Compared to single-sided clamping, this reduces the risk of surface deformation, indentation, and other damage to the guide rail, extends its service life, and reduces the problem of decreased equipment accuracy due to improper clamping.

[0035] Example 2 of the clamping component;

[0036] In this embodiment, refer to Figure 6 As shown, the clamping component includes two second clamping blocks 48, which are connected to the mounting groove by two bolts 6. The side wall of the second clamping block 48 is provided with a circular notch 49, and an arc-shaped anti-slip pad 50 is provided in the circular notch 49. The arc-shaped anti-slip pad 50 ensures that when clamping the circular guide rail, slippage will not occur and the surface of the square guide rail will not be damaged.

[0037] When installing the protective cover body 1 onto the circular guide rail, the two second clamping blocks 48 approach each other, causing the two circular notches 49 on the second clamping blocks 48 to clamp and fix the circular guide rail in place. The circular notches 49 are height-matched to the contour of the circular guide rail. When the two second clamping blocks 48 approach each other, they can fit the circumference of the guide rail in all directions without dead angles, achieving precise positioning and stable clamping. This prevents the protective cover 10 from shifting or shaking due to vibration and impact during processing, ensuring stable operation of the protective function. This clamping method ensures that the force on the circular guide rail is evenly distributed around the circumference, effectively avoiding guide rail deformation and wear caused by local stress concentration. Compared with unilateral pressure or irregular clamping, it can significantly extend the service life of the guide rail while maintaining the high-precision operation of the equipment.

[0038] During the installation of the protective cover body 1, selecting the appropriate clamping method for different types of guide rails, such as square and round ones, can significantly optimize the installation effect of the protective cover 10 and the operating performance of the equipment. Selecting the corresponding clamping method ensures precise fit to the guide rail contour. Square guide rails are secured without gaps using flat clamping blocks, while round guide rails are tightly wrapped around the circumference using clamping blocks with circular notches 49, improving stability. This ensures uniform force on the guide rails, avoiding localized stress concentration that could cause deformation and wear, thus extending service life. The operation is simple and quick, reducing the threshold and time cost of installation and maintenance. It also enhances sealing performance, effectively preventing the intrusion of cutting fluid and chips, providing comprehensive protection for the safe operation of the equipment.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
