Description

Technical Field

[0001] This utility model relates to the field of gantry machining technology, and in particular to a semi-protective structure for gantry machining centers. Background Technology

[0002] Gantry machining centers are machining centers with the spindle axis perpendicular to the worktable. During the cutting process of the workpiece, a large amount of waste chips are generated, which are easily scattered everywhere. Most existing gantry machining centers lack protective mechanisms, which is a certain defect.

[0003] A search revealed a Chinese patent (authorization announcement number CN220805650U) disclosing a semi-protective structure for a gantry machining center. This structure includes a U-shaped base with U-shaped grooves at both ends of its top. A fixed plate is fixedly connected inside the U-shaped base, and a threaded rod is rotatably connected between the top of the fixed plate and the bottom of the U-shaped base. A movable plate is threadedly connected to the outside of the threaded rod. This semi-protective structure for the gantry machining center utilizes U-shaped grooves and U-shaped covers. While this patented technology can achieve a semi-protective effect by using two U-shaped covers together to prevent accidental injury to workers from flying debris during machining, the fixed position of the U-shaped covers means that when machining long workpieces, the extension path of the U-shaped covers may interfere with the workpiece's placement, preventing the U-shaped covers from extending and providing protection, thus reducing the applicability of the protective structure.

[0004] To address the aforementioned problems, this utility model proposes a semi-protective structure for gantry machining centers. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a semi-protective structure for gantry machining centers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a semi-protective structure for a gantry machining center, including a support base, a gantry frame fixedly installed on the upper surface of the support base, protective plates being lifted and lowered on both sides of the gantry frame, a plurality of assembly slots evenly opened at the bottom of the protective plates, a fixing tube being embedded in the interior of each assembly slot, a telescopic rod being slidably installed inside the fixing tube, a spring being fixedly installed at the top of the interior of the fixing tube, the other end of the spring being fixedly connected to the telescopic rod, and a silicone pad being fixedly installed at the bottom of each telescopic rod; guide grooves are opened on the upper surface of the support base corresponding to the positions of the telescopic rods on both sides; the silicone pads and guide grooves are correspondingly transitionally fitted.

[0007] The present invention is further configured such that a slag discharge port is provided on the upper end of the support base corresponding to one end of the guide groove, and a collection basket is detachably installed on the lower end of the support base corresponding to the slag discharge port.

[0008] The present invention is further configured such that a fixing plate is fixedly installed on the top of the side of the gantry away from the slag discharge port, a first electric push rod is fixedly installed on the fixing plate, the output end of the first electric push rod extends downward and a fan is fixedly installed thereon, and the air outlet of the fan faces the guide groove and is inclined.

[0009] The present invention is further provided that observation windows are provided on both the front and rear sides of the gantry frame.

[0010] The present invention is further configured such that a second electric push rod is fixedly connected to the top of the gantry frame, and the piston rod of the second electric push rod extends into the interior of the gantry frame and is fixedly connected to a cutting assembly.

[0011] The present invention is further configured such that the lower end surface of the support base is made of metal, and magnetic strips are fixedly installed on both sides of the top of the collection basket, so that the collection basket is attracted to the lower end surface of the support base by the magnetic strips.

[0012] The present invention is further configured such that slide rails are provided on both sides of the gantry frame corresponding to the two ends of the protective plate, a screw is rotatably installed in one slide rail, and sliders are fixedly installed on both sides of the protective plate, with the screw threadedly connected to the corresponding sliders.

A motor is fixedly installed at the top of the gantry frame corresponding to the position of the screw, and the output shaft of the motor is fixedly connected to the screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This gantry machining center uses a semi-protective structure. By setting a fixed tube, telescopic rod, spring and silicone pad at the bottom of the protective plate, the operation process is as follows: when the protective plate moves down, the silicone pad contacts the long workpiece and pushes the telescopic rod to retract into the fixed tube and squeeze the spring. The spring rebound force can clamp the workpiece, which does not hinder the downward movement of the protective plate and can stabilize the workpiece to prevent it from shifting. 2. The gantry machining center uses a semi-protective structure, which includes a fixed plate, a first electric push rod, a fan, a slag discharge port, and a collection basket with magnetic strips. The operation process is that the fan blows waste chips into the guide groove after the electric push rod adjusts the position. The waste chips fall into the collection basket through the slag discharge port, realizing centralized cleaning of waste chips. The magnetic connection makes it easy to disassemble the collection basket. Attached Figure Description

[0017] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0018] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: A semi-protective structure for a gantry machining center includes a support base 1, on the upper end surface of which a gantry frame 2 is fixedly mounted; a second electric push rod 16 is fixedly connected to the top of the gantry frame 2, and the piston rod of the second electric push rod 16 extends into the interior of the gantry frame 2 and is fixedly connected to a cutting assembly 17.

[0020] By adopting the above technical solution, the second electric push rod 16 can accurately drive the cutting assembly 17 to move up and down, meeting the processing needs of workpieces of different heights. The structure is simple and the drive is stable.

[0021] The gantry frame 2 has slide rails 18 on both sides corresponding to the two ends of the protective plate 3. A screw 19 is rotatably installed in one slide rail 18. A slider 20 is fixedly installed on both sides of the protective plate 3. The screw 19 is threadedly connected to the corresponding slider 20. A guide rod is fixedly installed in the slide rail 18 on the other side. The guide rod is slidably connected to the corresponding slider 20. A motor 21 is fixedly installed at the top of the gantry frame 2 at the position corresponding to the screw 19. The output shaft of the motor 21 is fixedly connected to the screw 19.

[0022] By adopting the above technical solution, the motor 21 drives the screw 19 to rotate, and with the sliding cooperation of the slider 20 with the slide rail 18 and the guide rod, the protective plate 3 can be raised and lowered smoothly and accurately, ensuring that the protective plate 3 does not deviate during the movement and improving the reliability of the protective structure.

[0023] Both sides of the gantry frame 2 are equipped with protective plates 3. The bottom of the protective plates 3 is evenly provided with several assembly slots 4. The assembly slots 4 are all fitted with fixed tubes 5. The fixed tubes 5 are slidably installed with telescopic rods 6. The top of the fixed tubes 5 is fixedly installed with springs 7. The other end of the springs 7 is fixedly connected to the telescopic rods 6. The bottom of the telescopic rods 6 is fixedly installed with silicone pads 8. The upper end of the support base 1 is provided with guide grooves 9 corresponding to the positions of the telescopic rods 6 on both sides. The silicone pads 8 and the guide grooves 9 are fitted together.

[0024] By adopting the above technical solution, when the protective plate 3 descends, the silicone pad 8 can be inserted into the guide groove 9 to form a semi-closed state, effectively blocking the splashing of waste chips; when the workpiece is long, after the silicone pad contacts the workpiece, the telescopic rod 6 can retract the fixing tube 5 and compress the spring 7, which not only does not hinder the descent of the protective plate 3, but also clamps the workpiece through the spring force, realizing the dual functions of protection and workpiece fixation.

[0025] The upper end of the support base 1 is provided with a slag discharge port 10 corresponding to the end of the guide groove 9. The lower end of the support base 1 is detachably installed with a collection basket 11 corresponding to the slag discharge port 10. The lower end of the support base 1 is made of metal. Magnetic strips are fixedly installed on both sides of the top of the collection basket 11. The collection basket 11 is attracted to the lower end of the support base 1 by the magnetic strips. A fixing plate 12 is fixedly installed on the top of the side of the gantry frame 2 away from the slag discharge port 10. A first electric push rod 13 is fixedly installed on the fixing plate 12. The output end of the first electric push rod 13 extends downward and is fixedly installed with a fan 14. The air outlet of the fan 14 faces the guide groove 9 and is set at an angle.

[0026] By adopting the above technical solution, the blower 14 can blow the waste in the guide trough 9 toward the slag discharge port 10. The waste falls into the collection basket 11 through the slag discharge port 10, realizing the centralized collection of waste. The collection basket 11 is connected to the support base 1 by a magnetic strip, which facilitates quick disassembly and cleaning and reduces maintenance difficulty.

[0027] Observation windows 15 are provided on both the front and rear sides of the gantry frame 2. Workers can observe the workpiece processing status in real time through the observation windows 15 without opening the protective structure, which ensures both convenient observation and protection.

[0028] Working principle: In use, first, the workpiece to be processed is smoothly pushed into the gantry 2 on the upper surface of the support base 1 and adjusted to the processing position directly below the cutting component 17. Then, the equipment is started, and the second electric push rod 16 at the top of the gantry 2 extends, and its piston rod drives the cutting component 17 connected to the end to move down until it reaches the appropriate processing height, and then the workpiece is cut. To prevent the waste generated during processing from flying everywhere, the motor 21 at the top of the gantry 2 is started simultaneously. The output shaft of the motor 21 drives the screw 19 in the slide rail 18 on one side to rotate. Since the sliders 20 on both sides of the protective plate 3 are threadedly connected to the screw 19 and slidingly engaged with the guide rod in the slide rail 18 on the other side, the rotational motion of the screw 19 is converted into the linear motion of the slider 20, which drives the protective plate 3 to move smoothly downward along the slide rail 18. As the protective plate 3 moves downward, the telescopic rod 6 in the fixed tube 5 inside the mounting groove 4 at its bottom moves downward simultaneously. Finally, the silicone pad 8 at the bottom of the telescopic rod 6 precisely aligns with and engages with the guide groove 9 on the support base 1, creating a semi-enclosed protective space inside the gantry 2. This effectively blocks debris from splashing, ensuring worker safety, while also allowing workers to observe the processing progress through the reserved space above. If the workpiece to be processed is long, after the silicone pad 8 moves downward and contacts the workpiece, it will push the telescopic rod 6 to retract into the fixed tube 5 and compress the spring 7. This does not hinder the protective plate 3 from continuing to move downward, while the spring 7's rebound force provides stable clamping to the workpiece, ensuring that the workpiece does not shift during processing and achieving stable processing.

[0029] It should be noted that all the devices in this application are common devices on the market, and can be selected according to the needs of specific use. The circuit connection relationship of each device is a simple series and parallel connection circuit. There is no innovation in the circuit connection. Those skilled in the art can easily implement it. It belongs to the prior art and will not be described in detail.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
