Description

Technical Field

[0001] The utility model relates to the technical field of numerical control milling machines, and more particularly to an automatic dust cover bracket for a moving column gantry side milling head. Background Art

[0002] A milling machine primarily uses a milling cutter to machine various workpiece surfaces. The primary motion is usually the rotation of the cutter, while the movement of the workpiece and cutter is the feed motion. It can process flat surfaces, grooves, various curved surfaces, gears, and more. A milling machine is a versatile machine tool that can process flat surfaces (horizontal and vertical), grooves (keyways, T-slots, dovetail slots, etc.), toothed parts (gears, spline shafts, sprockets), helical surfaces (threads, spiral grooves), and various curved surfaces. It can also be used for machining rotating surfaces, internal holes, and cutting. When the milling machine is working, the workpiece is mounted on the workbench or accessories such as the dividing head. The rotation of the milling cutter is the main motion, supplemented by the feed motion of the workbench or the milling head. The workpiece can obtain the required processing surface. The CNC milling machine is an automatic processing equipment developed on the basis of the general milling machine. The processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. Among them, the CNC milling machine with tool magazine is also called a machining center. In order to effectively prevent chips, dust and other impurities generated during the processing from entering the side milling head, a dust cover needs to be installed on the side milling head.

[0003] However, the existing automatic dust cover bracket for the moving column gantry side milling head has the following problems when in use:

[0004] Existing dust covers are usually fixed and will always occupy a large space whether in use or not. In addition, due to their fixed position, they may hinder operators when performing operations such as installation, debugging, and maintenance of the milling head, making the operation process cumbersome and inconvenient. Secondly, the position of the fixed dust cover cannot be changed. In the face of processing environments of different lengths, the length of the dust cover cannot be adjusted, which lacks flexibility and cannot meet diverse needs.

[0005] The utility model can play the role of being able to shrink when the dust cover is not used, and can freely adjust the output length of the dust plate according to changes in the processing environment. Utility Model Content

[0006] The utility model aims to solve the technical problems raised by the above-mentioned background technology and provides an automatic dust cover bracket for a moving column gantry side milling head.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic dust cover bracket for a moving column gantry side milling head, comprising: a base plate, slide rails are fixedly installed on the upper and lower sides of the front of the base plate, moving blocks are slidably connected to the front of the slide rails, a fixed plate is fixedly installed on the front of the moving block, a dust cover is arranged on the front of the fixed plate, the dust cover is composed of an upper dust cover plate, a left dust cover plate and a right dust cover plate, and the upper dust cover plate, the left dust cover plate and the right dust cover plate are arranged around the front of the fixed plate.

[0008] A further preferred solution: baffles are threadedly connected to the left and right ends of the base plate, a motor is fixedly installed on the outer end surface of the baffle at the left end of the base plate, a screw is rotatably connected between the baffles, the left end of the screw is fixedly connected to the motor output end, and the screw is threadedly connected to the fixed plate.

[0009] A further preferred solution is that the upper and lower ends of the slide rail are both provided with slide grooves, the slide grooves and the slide rail form an I-shape, and the slide grooves are slidably connected to the moving block.

[0010] A further preferred solution is that sliders are fixedly installed at the upper and lower ends of the movable block, and the sliders are slidably connected to the sliding grooves.

[0011] A further preferred solution is that screw holes are provided at both left and right ends of the fixing plate, and the screw rods are threadedly connected to the screw holes.

[0012] A further preferred solution: the upper dustproof plate, left dustproof plate and right dustproof plate have the same structure, a slot is provided on the front of the upper dustproof plate, a limiting hole is provided on the front side of the upper end of the upper dustproof plate, an output plate is embedded and installed inside the slot, and the output plate is threadedly connected to the upper dustproof plate, and a number of adjustment holes are provided at equal distances on the left and right sides of the upper end of the output plate.

[0013] A further preferred solution is that the output plate is threadedly connected to the upper dustproof plate through an adjustment hole and a limit hole.

[0014] Beneficial effects:

[0015] 1. By providing a slide groove, a slide rail, a moving block and a slider, the slide groove and the slide rail form an I-shaped structure. This design provides a clear guide for the movement of the moving block. The slider inside the moving block cooperates closely with the slide groove, so that the moving block can only move linearly along the length direction of the slide rail, avoiding deviation or shaking in other directions. This precise guiding effect ensures that the dust cover can accurately follow the movement of the fixed plate when adjusting its position, thereby better fitting the side milling head and improving the dustproof effect. At the same time, the cooperation of the slider and the slide groove also increases the contact area between the moving block and the slide rail, disperses the pressure, and reduces the risk of local wear and deformation. This stable support helps to maintain the position stability of the dust cover during operation and prevents the dustproof effect from being affected by vibration or external force interference;

[0016] 2. The output plate is embedded in the dustproof plate through the slot and is threadedly connected to the dustproof plate through the adjustment and limit holes. This allows the position of the output plate to be adjusted according to different processing requirements. For example, when processing larger workpieces, the output plate can be extended to a longer length to better cover the side milling head and improve dust prevention. When processing smaller workpieces, the output plate can be retracted to avoid interference with the workpiece.

[0017] 3. In summary, this type of dynamic column gantry side milling head automatic dust cover bracket is provided with structures such as a slot and an output plate. The setting of multiple adjustment holes allows the output plate to be fixed in different positions and can be flexibly adjusted according to different processing requirements. Whether facing workpieces of different sizes or adapting to changes in various cutting forces, the best dust prevention effect can be achieved by adjusting the position, material or thickness of the output plate, and the side milling head position and working state can be quickly responded to changes in the actual operation. This flexibility not only improves work efficiency, but also reduces the time wasted due to frequent adjustment of the dust cover. After use, the output plate can be conveniently adjusted through the adjustment hole and the limit hole, and the output plate can be fully inserted into the slot, reducing the space occupied by the dust cover.

[0023] The following is a combination of the appended examples of the present invention Figures 1-4 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0024] See also Figure 1-4 In the embodiment of the present invention, an automatic dust cover bracket for a moving column gantry side milling head includes: a base plate 1, a slide rail 2 is fixedly installed on the upper and lower sides of the front of the base plate 1, a moving block 3 is slidably connected to the front of the slide rail 2, a fixed plate 4 is fixedly installed on the front of the moving block 3, a dust cover 5 is provided on the front of the fixed plate 4, and the dust cover 5 is composed of an upper dust cover plate 501, a left dust cover plate 502 and a right dust cover plate 503. The upper dust cover plate 501, the left dust cover plate 502 and the right dust cover plate 503 are arranged around the front of the fixed plate 4, and the left and right ends of the base plate 1 are threadedly connected with a baffle 101, and the outer end surface of the baffle 101 at the left end of the base plate 1 is fixedly installed with a motor 102. A screw rod 103 is rotatably connected between 101, and the left end of the screw rod 103 is fixedly connected to the output end of the motor 102. The screw rod 103 is threadedly connected to the fixed plate 4. Screw holes 401 are provided at both ends of the fixed plate 4. The screw 103 is threadedly connected to the screw holes 401. The base plate 1 serves as the basic installation component of the entire bracket, providing stable support for other components. It is fixed to a suitable position of the moving column gantry machining center by bolts and the like. Then, the slide rail 2 is installed on the front of the base plate 1, and then the moving block 3 is slidably connected to the slide rail 2 so that the moving block 3 can slide on the slide rail 2. Then, the fixed plate 4 is installed on the two moving blocks 3, which is a dust cover. 5 provides a basis for the installation, and then the upper dustproof plate 501, the left dustproof plate 502 and the right dustproof plate 503 are installed on the fixed plate 4 in sequence to form a dust cover 5, and finally the baffle 101 on the left end of the bottom plate 1 is installed, and then the screw 103 and the motor 102 are installed, and when installing the screw 103, it passes through the fixed plate 4 and is threadedly connected with the fixed plate 4, and finally the baffle 101 at the other end is installed to complete the installation of the entire component. When in use, start the motor 102, and the output end of the motor 102 drives the screw 103 to start rotating. As the screw 103 rotates, since the screw 103 is threadedly connected with the screw hole 401 on the fixed plate 4 The fixed plate 4 is connected to the slide rail 2 through the moving block 3, which limits the rotational movement of the fixed plate 4, so that the fixed plate 4 can only move in a straight line along the slide rail 2, and move along the slide rail 2 toward or away from the side milling head. Since the dust cover 5 is composed of an upper dust cover plate 501, a left dust cover plate 502 and a right dust cover plate 503, and surrounds the front of the fixed plate 4, the movement of the fixed plate 4 will drive the dust cover 5 to move together. Through the forward and reverse rotation of the motor 102, the moving direction and distance of the fixed plate 4 can be accurately controlled, so that the dust cover 5 can be adjusted according to the position and working status of the side milling head, ensuring that the dust cover 5 fits tightly around the side milling head.

[0025] In the embodiment of the present invention, a slide groove 201 is provided at the upper and lower ends of the slide rail 2, and the slide groove 201 forms an I-shape with the slide rail 2. The slide groove 201 is slidably connected to the moving block 3, and sliders 301 are fixedly installed at the upper and lower ends of the inside of the moving block 3, and the slider 301 is slidably connected to the slide groove 201. The slide grooves 201 opened at the upper and lower ends of the slide rail 2 form an I-shaped structure with the slide rail 2. The I-shaped structure provides a larger support area in the vertical direction, making the moving block 3 more stable during the sliding process and not prone to shaking or tilting, and the shape of the slide groove 201 can effectively limit the movement direction of the moving block 3, ensuring that it can only slide along the length direction of the slide rail 2. When the motor 102 drives the screw 103 to rotate, the fixed plate 4 threadedly connected to the screw 103 will be subjected to the thrust or pull of the screw 103, thereby driving the moving block 3 to slide on the slide rail 2. The slider 301 inside the moving block 3 slides in the slide groove 201, ensuring that the movement direction and trajectory of the moving block 3 are consistent with the slide rail 2, driving the dust cover 5 to move with the fixed plate 4, thereby realizing dustproof protection for the side milling head of the moving column gantry. The position of the dust cover 5 can also be automatically adjusted according to the working position and status of the side milling head to improve the dustproof effect.

[0026] In the embodiment of the present utility model, the upper dustproof plate 501, the left dustproof plate 502 and the right dustproof plate 503 have the same structure. A slot 504 is provided on the front of the upper dustproof plate 501, and a limiting hole 505 is provided on the front side of the upper end of the upper dustproof plate 501. An output plate 506 is embedded in the slot 504, and the output plate 506 is threadedly connected to the upper dustproof plate 501. A plurality of adjustment holes 507 are provided on the left and right sides of the upper end of the output plate 506 at equal distances. The output plate 506 is threadedly connected to the upper dustproof plate 501 through the adjustment holes 507 and the limiting holes 505. The plate 502 and the right dustproof plate 503 have the same structure. This design is conducive to improving production efficiency and reducing costs. During the manufacturing process, the same process and mold can be used for production, reducing production preparation time and cost. At the same time, the consistent structure also facilitates installation and maintenance. When one of the dustproof plates has a problem, it can be quickly replaced, which improves the reliability of the equipment. The output plate 506 can be replaced or adjusted as needed to adapt to different processing requirements. For example, the output plate 506 of different materials or thicknesses can be replaced to improve the dustproof effect or adapt to different cutting conditions. Force, the limiting hole 505 and the several adjustment holes 507 on the left and right sides of the upper end of the output plate 506 are equidistantly opened for realizing the threaded connection and position adjustment of the output plate 506 with the upper dustproof plate 501, the left dustproof plate 502 and the right dustproof plate 503. By selecting different adjustment holes 507 for threaded connection with the limiting holes 505, the extension length of the output plate 506 can be adjusted to better adapt to different processing conditions. When the milling head on the moving column gantry side is working, the dust cover bracket will automatically adjust according to the position and working state of the milling head. The upper dustproof plate 501, the left dustproof plate 502 and the right dustproof plate 503 surround the front of the fixed plate 4 to form a closed space, enclosing the milling head. The output plate 506 can be adjusted as needed to better adapt to different processing requirements. When the output plate 506 needs to be replaced or adjusted, the output plate 506 can be removed from the slot 504 by loosening the threaded connection, and then a suitable output plate 506 can be selected for installation and adjustment. The position of the output plate 506 can be adjusted by threading different adjustment holes 507 with the limit holes 505, thereby improving the flexibility and adaptability of the dust cover.

[0027] Working principle: When the moving column gantry side milling head starts working, the motor 102 is started, and the output end of the motor 102 drives the screw 103 to start rotating. As the screw 103 rotates, the fixed plate 4 is pushed by the screw 103 and moves along the slide rail 2 toward or away from the side milling head. Since the fixed plate 4 is fixedly connected to the moving block 3, and the slider 301 inside the moving block 3 slides in the slide groove 201 of the slide rail 2, it can ensure that the movement direction and trajectory of the moving block 3 are consistent with the slide rail 2, thereby making the movement trajectory of the fixed plate 4 also consistent with the side milling head. The slide rails 2 are consistent. Since the dust cover 5 surrounds the front of the fixed plate 4, the movement of the fixed plate 4 will drive the dust cover 5 to move together. The moving direction and distance of the fixed plate 4 can be accurately controlled by the forward and reverse rotation of the motor 102, so that the dust cover 5 can be adjusted according to the position and working state of the side milling head, ensuring that the dust cover 5 fits tightly around the side milling head, preventing impurities such as chips and dust from entering the inside of the side milling head, and protecting the precision parts of the side milling head. The speed and direction of the motor 102 can be adjusted at any time according to the actual situation during the processing. In order to achieve fine adjustment of the position of the dust cover 5, when it is necessary to adjust the output length of the dust cover 5 or adjust the material according to processing requirements, the adjustment hole 507 and the limit hole 505 are threadedly connected to the dust plate, and the material, thickness or extension length of the output plate 506 can be replaced or adjusted according to different processing requirements. By selecting different adjustment holes 507 and the limit hole 505 for threaded connection, the position of the output plate 506 can be adjusted to improve the flexibility and adaptability of the dust cover 5. When the side milling head finishes working, the motor 102 is turned off. At this time, the dust cover bracket stops working, the fixing plate 4 and the dust cover 5 remain in the current position, waiting for the next start, and by loosening the threaded connection between the output plate 506 and the upper dust cover plate 501, the left dust cover plate 502 and the right dust cover plate 503, the output plate 506 can be fully inserted into the slot 504, and then the output plate 506 is fixed and limited by the limiting hole 505 and the adjustment hole 507 to achieve the contraction of the dust cover 5 and prevent the output plate 506 from falling out of the slot 504, thereby reducing the space occupied by the dust cover 5 when not in use.
