Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a spindle box of a gantry machining center with a protective structure. Background Technology

[0002] In today's booming modern manufacturing industry, gantry machining centers have been widely used in many fields such as machinery manufacturing, aerospace, and automotive parts processing due to their high precision and high efficiency. As one of the core components of a gantry machining center, the performance of the spindle box directly affects the machining quality and production efficiency of the entire machining center.

[0003] In some traditional spindle boxes, dust and other debris can easily enter the spindle box through the heat dissipation grooves when the machine is idle or during processing, leading to accelerated wear of components. In addition, during long-term continuous processing, a large amount of heat can easily accumulate inside the spindle box, resulting in a decrease in equipment performance. In order to solve the above problems, this utility model provides a gantry machining center spindle box with a protective structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gantry machining center spindle box with a protective structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A gantry machining center spindle box with a protective structure includes a spindle box body and two support beams. A mounting frame is fixedly connected to the front of the spindle box body. An electric push rod is fixedly installed inside the mounting frame. Mounting frames are fixedly connected to both sides of the mounting frame. Protective plates are movably connected inside the two mounting frames. L-shaped connecting rods are fixedly connected to the upper ends of the two protective plates. The other ends of the two L-shaped connecting rods are fixedly connected to the telescopic ends of the electric push rods. The upper ends of the front of the two support beams are fixedly connected to the same crossbeam. An adjustment assembly is provided between the two support beams.

[0006] As a further improvement of this utility model, the adjusting component includes a threaded screw rotatably connected to the upper end between two supporting beams via a bearing. A movable block is threaded onto the surface of the threaded screw, and a connecting frame is fixedly connected to the front of the movable block. The front of the connecting frame is fixedly connected to the main body of the spindle box.

[0007] As a further improvement of this utility model, a drive motor is fixedly connected to the upper end of one side of the supporting beam, and the power end of the drive motor is fixedly connected to the threaded screw.

[0008] As a further improvement of this utility model, a groove is provided on the upper surface of the crossbeam, and a slider that matches the groove is fixedly connected to the lower surface of the connecting frame.

[0009] As a further improvement of this utility model, several heat dissipation slots are provided on both sides of the main body of the spindle box, and mounting slots are provided on both sides of the main body of the spindle box, with a heat dissipation fan fixedly installed inside the mounting slot.

[0010] As a further improvement of this utility model, a mounting box is fixedly connected to the upper end of the main body of the spindle box.

[0011] As a further improvement of this utility model, the main body of the spindle box has several threaded holes on the front side, and the two sides of the mounting bracket are threaded with several mounting bolts that are compatible with the threaded holes.

[0012] As a further improvement of this utility model, a machining head is fixedly connected to the lower end of the main body of the spindle box.

[0013] The beneficial effects of this utility model are: By installing a protective plate, the main body of the spindle box is effectively protected. During processing or idle periods, the electric push rod can drive the protective plate to descend, completely blocking both sides of the spindle box. This effectively prevents external debris from entering the spindle box, avoiding damage to internal precision components, reducing equipment failure rate, extending the service life of the spindle box, and ensuring safe and stable operation of the equipment in complex processing environments. When the equipment temperature is high, the protective plate is opened, and the cooling fan is activated simultaneously. Working in conjunction with the heat dissipation tank, the heat generated inside the spindle box can be quickly dissipated, preventing problems such as equipment performance degradation and component aging caused by excessive temperature. This ensures stable performance of the equipment during long-term continuous processing, improving the continuity and reliability of production.

[0014] By setting up adjustment components, during use, the drive motor drives the threaded screw to rotate, which in turn causes the movable block to move the main body of the spindle box. With the guiding effect of the slider and the slide groove, the smoothness and accuracy of the movement are ensured. In actual processing, the position of the main body of the spindle box can be quickly and accurately adjusted according to the processing requirements of different workpieces, which improves processing efficiency and also helps to improve processing accuracy, meeting the requirements of high-precision processing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 A gantry machining center spindle box with a protective structure includes a spindle box body 1 and two support beams 2. The spindle box body 1 has a mounting frame 3 fixedly connected to its front side. An electric push rod 4 is fixedly installed inside the mounting frame 3. Mounting frames 5 are fixedly connected to both sides of the mounting frame 3. Protective plates 6 are movably connected inside the two mounting frames 5. L-shaped connecting rods 7 are fixedly connected to the upper ends of the two protective plates 6. The other ends of the two L-shaped connecting rods 7 are fixedly connected to the telescopic ends of the electric push rod 4. The upper ends of the front sides of the two support beams 2 are fixedly connected to the same crossbeam 8. An adjustment assembly is provided between the two support beams 2.

[0021] In this invention, the adjustment assembly includes a threaded screw 9 rotatably connected to the upper end between two supporting beams 2 via bearings. A movable block 10 is threadedly fitted onto the surface of the threaded screw 9. A connecting frame 11 is fixedly connected to the front of the movable block 10. The threads on the inner wall of the movable block 10 are engaged with the threads of the threaded screw 9. When the threaded screw 9 rotates, the movable block 10 can move linearly along the axial direction of the threaded screw 9 to achieve precise position adjustment. The front of the connecting frame 11 is fixedly connected to the main body 1 of the spindle box. After the connecting frame 11 is fixedly connected to the movable block 10, it can stably follow the movement of the movable block 10, so that the main body 1 of the spindle box can change position as the connecting frame 11 moves to meet the needs of different processing scenarios.

[0022] One of the supporting beams 2 has a drive motor 12 fixedly connected to the upper end of one side. The power end of the drive motor 12 is fixedly connected to the threaded screw 9. When the drive motor 12 starts, its power can be directly transmitted to the threaded screw 9, causing the threaded screw 9 to rotate, thereby realizing the power drive of the entire adjustment assembly. The upper surface of the crossbeam 8 is provided with a slide groove 13. The lower surface of the connecting frame 11 is fixedly connected with a slider 14 that matches the slide groove 13. The shape of the slider 14 matches the slide groove 13, allowing it to slide smoothly within the slide groove 13. At the same time, it limits the movement of the connecting frame 11, preventing the connecting frame 11 from shifting during movement and ensuring the stability and accuracy of the movement of the main spindle box body 1.

[0023] Several heat dissipation slots 15 are provided on both sides of the main body 1 of the spindle box. The heat dissipation slots 15 are evenly distributed on both sides of the main body 1 of the spindle box. The size and shape of their openings can effectively increase the contact area between the main body 1 of the spindle box and the outside air, and promote heat dissipation. Mounting slots are provided on both sides of the main body 1 of the spindle box. A cooling fan 16 is fixedly installed inside the mounting slot. The cooling fan 16 can accelerate the air flow and quickly dissipate the heat generated inside the main body 1 of the spindle box, ensuring that the main body 1 of the spindle box operates at a suitable temperature. A mounting box 17 is fixedly connected to the upper end of the main body 1 of the spindle box. Several threaded holes are provided on the front of the main body 1 of the spindle box. Several mounting bolts 18 that are compatible with the threaded holes are threadedly connected to both sides of the mounting bracket 3. A machining head 19 is fixedly connected to the lower end of the main body 1 of the spindle box. The machining head 19 can meet the machining requirements of different workpieces.

[0024] In use, the main spindle box body 1 is positioned between the two supporting beams 2 via an adjustment assembly. When the drive motor 12 is started, its power end drives the threaded screw 9, which is rotatably connected to the upper end between the two supporting beams 2 via bearings. The movable block 10, threaded onto the surface of the threaded screw 9, moves accordingly. The connecting frame 11 on the front of the movable block 10 drives the main spindle box body 1 to move, and the slider 14 on the lower surface of the connecting frame 11 slides within the groove 13 on the upper surface of the crossbeam 8, ensuring stable movement. When the device is not in use or the main unit temperature is low, the protective mechanism is closed, and the telescopic end of the electric push rod 4 retracts. The L-shaped connecting rod 7 drives the two protective plates 6 to move downwards within the mounting frame 5 until the protective plates 6 completely cover the front of the spindle box body 1. At this time, the cooling fans 16 fixedly installed in the mounting slots on both sides of the spindle box body 1 stop working, and the protective plates 6 provide protection. When the temperature is high and it is necessary to open the protection and dissipate heat, the telescopic end of the electric push rod 4 extends, and the L-shaped connecting rod 7 drives the two protective plates 6 to move upwards within the mounting frame 5, exposing the front of the spindle box body 1. At the same time, the cooling fans 16 start, and together with the heat dissipation slots 15 opened on both sides of the spindle box body 1, they dissipate heat inside the spindle box body 1.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
