Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a large gantry machining center that integrates vertical and horizontal operation. Background Technology

[0002] A gantry machining center, also known as a gantry machining tool, refers to a machining center whose spindle Z-axis is perpendicular to the worktable. Its overall structure is a large machining center with a portal frame formed by two columns and a top beam. There is also a crossbeam in the middle of the two columns. It is particularly suitable for machining large and complex-shaped workpieces. There are various types of gantry machining centers, including fixed-beam, moving-beam, moving-column, overhead crane, and composite types. Their machining characteristics, capabilities, and intended product processing applications differ. The telescopic cover of the machine tool is an important protective device, mainly used to protect key components such as guideways and lead screws from chips, coolant, and oil contamination, while also ensuring operator safety.

[0003] During the machining process of existing gantry machining centers, chips easily get embedded in the gaps of the telescopic cover of the machine tool's work platform or on the guide rails, causing the telescopic cover to jam and the seal to fail. When operators clean the chips, they are forced to use sharp tools to scrape the cover, causing surface scratches. Severe wear and precision loss will shorten the service life of the machine tool. Traditional chip suction systems are simple adsorption systems, and the cleaning method is difficult to remove small, embedded chips, resulting in a high residue rate. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A large vertical / horizontal integrated gantry milling machine tool includes a machine tool spindle body. The machine tool spindle body includes a machine tool guide rail and a worktable. A telescopic cover device is fixedly installed at one end of the machine tool guide rail. The telescopic cover device includes a support plate. Several sets of cover plates are arranged between the support plates. A chip suction assembly is fixedly installed on the upper surface of the support plate. The chip suction assembly includes a mounting plate, a suction hood, a servo motor, a main centrifugal pump, a chip discharge pipe, and a chip collection box. The mounting plate is fixedly installed around the perimeter of the support plate and a suction pipe is arranged in the middle of the mounting plate. The suction hood is fixedly installed on the upper surface of the mounting plate. The suction pipe is installed through the interior of the mounting plate. The servo motor is fixedly installed on the top wall of the suction hood. The rotating end of the servo motor is fixedly installed with the main centrifugal pump, which is located inside the suction hood. The chip discharge pipe is inserted into the side wall of the suction hood. The chip collection box is located on one side of the bottom end of the chip discharge pipe.

[0006] As an improvement to the above technical solution, bolts are fixedly installed between the four sides of the mounting plate and the support plate, and an inverted trapezoidal adsorption mask is fixedly installed on the bottom wall of the mounting plate.

[0007] As an improvement to the above technical solution, a secondary centrifugal pump is fixedly installed at the bottom of the main centrifugal pump, and the secondary centrifugal pump is inserted into the inside of the suction pipe.

[0008] As an improvement to the above technical solution, a connecting seat is provided at the top of the chip removal pipe and the side wall of the suction hood.

[0009] As an improvement to the above technical solution, the mounting plate is located below the retracted cover plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a timed servo motor to start, driving the main centrifugal pump to rotate at high speed, creating a negative pressure area inside the suction hood. The negative pressure is transmitted through the suction pipe to the gap area of ​​the telescopic cover device, sucking the accumulated chips into the suction hood. The chips then enter the main centrifugal pump with the airflow, are separated by centrifugal force, and enter the chip discharge pipe. The chips then enter the chip collection box through the chip discharge pipe, completing automated collection. Coolant and other liquids are separated from the chips through a filtration device, achieving solid-liquid separation and automated cleaning, reducing manual labor. The chip suction component uses negative pressure adsorption and centrifugal separation technology to achieve automated chip cleaning, significantly reducing the frequency and labor intensity of manual cleaning, improving machine tool accuracy and lifespan. Timely chip cleaning can prevent them from entering key components such as machine tool guide rails and internal lead screws, reducing wear and accuracy loss, and extending the service life of the machine tool.

[0012] 2. The inverted trapezoidal adsorption mask of this utility model has a shape design that helps to increase the adsorption area and improve the adsorption efficiency. Its funnel-shaped opening can better fit and wrap the chips, thereby more effectively sucking the chips into the chip suction assembly. The main centrifugal pump and the auxiliary centrifugal pump are connected in series to form a multi-stage suction system. The main pump provides basic negative pressure, and the auxiliary pump directly contacts the chip accumulation area by inserting the suction pipe to form a local strong suction field. The synergistic effect can significantly improve the system's adsorption capacity for fine chips or tightly embedded debris. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] A large gantry-type machining center integrating vertical and horizontal operation includes a machine tool spindle body 1. The machine tool spindle body 1 includes a machine tool guide rail 11 and a worktable 12. A telescopic cover device 2 is fixedly installed at one end of the machine tool guide rail 11. The telescopic cover device 2 includes a support plate 21, and several sets of cover plates 22 are arranged between the support plates 21. A chip suction assembly 3 is fixedly installed on the upper surface of the support plate 21. The chip suction assembly 3 includes a mounting plate 31, a suction hood 33, a servo motor 34, a main centrifugal pump 35, a chip discharge pipe 36, and a chip collection box 37. The mounting plate 31... The mounting plate 31 is fixedly installed on the upper surface of the support plate 21. The middle part of the mounting plate 31 is provided with a suction pipe 312. The suction hood 33 is fixedly installed on the upper surface of the mounting plate 31. The suction pipe 312 is installed through the inside of the mounting plate 31. The servo motor 34 is fixedly installed on the top wall of the suction hood 33. The rotating end of the servo motor 34 is fixedly installed with the main centrifugal pump 35. The main centrifugal pump 35 is located inside the suction hood 33. The chip discharge pipe 36 is inserted into the side wall of the suction hood 33. The chip collection box 37 is located on one side of the bottom end of the chip discharge pipe 36.

[0021] In this embodiment, during the machining process, the cutting tool cuts the workpiece, and the generated chips scatter through the area of ​​the machine tool guide rail 11 and the telescopic cover device 2. When it is necessary to suck in the chips, the servo motor 34 is started by timed control, driving the main centrifugal pump 35 to rotate at high speed, forming a negative pressure area inside the suction hood 33. The negative pressure is transmitted to the gap area of ​​the telescopic cover device 2 through the suction pipe 312, sucking the accumulated chips into the suction hood 33. The chips enter the main centrifugal pump 35 with the airflow, and after being separated by centrifugal force, they enter the chip discharge pipe 36. The chips enter the chip collection box 37 through the chip discharge pipe 36, completing the automated collection. Coolant and other liquids are separated from the chips by a filtration device. The current solid-liquid separation process and automated cleaning reduce manual labor. The chip suction component 3 uses negative pressure adsorption and centrifugal separation technology to achieve automated chip cleaning, significantly reducing the frequency and labor intensity of manual cleaning, improving machine tool accuracy and lifespan. Timely chip cleaning can prevent it from entering the machine tool guide rail 11 and critical components such as the internal lead screw, reducing wear and accuracy loss, extending the machine tool's service life, and keeping the processing area clean. This vertical and horizontal integrated large gantry machining center achieves automated and efficient chip cleaning by integrating the chip suction component 3, significantly improving the machine tool's processing accuracy, stability, and safety, while optimizing the working environment and resource utilization.

[0022] Specifically, bolts 311 are fixedly installed around the perimeter of the mounting plate 31 and between it and the support plate 21, and an inverted trapezoidal adsorption mask 32 is fixedly installed on the bottom wall of the mounting plate 31.

[0023] In this embodiment, the mounting plate 31 is fixed to the support plate 21 by bolts 311 around its perimeter, ensuring a stable and reliable connection between the mounting plate 31 and the support plate 21, preventing loosening. When it is necessary to inspect or replace the components in the chip suction assembly 3, the mounting plate 31 and the support plate 21 can be easily separated by removing the bolts 311, facilitating subsequent maintenance operations. The inverted trapezoidal adsorption mask 32's shape design helps to increase the adsorption area and improve adsorption efficiency. Its funnel-shaped opening can better fit and wrap the chips, thereby more effectively sucking the chips into the chip suction assembly 3. The inverted trapezoidal design makes it difficult for the chips to escape after entering the adsorption mask, as the channel gradually narrows, further improving the reliability of adsorption.

[0024] Specifically, a secondary centrifugal pump 351 is fixedly installed at the bottom of the main centrifugal pump 35, and the secondary centrifugal pump 351 is inserted into the inside of the suction pipe 312.

[0025] In this embodiment, the main centrifugal pump 35 and the auxiliary centrifugal pump 351 are connected in series to form a multi-stage suction system. The main pump provides basic negative pressure, and the auxiliary pump directly contacts the chip accumulation area by inserting into the suction pipe 312, forming a local strong suction field. The synergistic effect can significantly improve the system's ability to adsorb small chips or tightly embedded debris, making it particularly suitable for efficient cleaning under complex working conditions. The plug-in design of the auxiliary centrifugal pump 351 shortens the suction transmission path and reduces the resistance loss of airflow in the suction pipe 312. By precisely controlling the speed and power of the auxiliary pump, the dynamic adjustment of the suction distribution can be achieved. For example, the local suction can be enhanced in the chip concentration area, thereby improving the overall chip suction efficiency. The chips generated during the processing may be filamentous, curled, or powdery, and are easily embedded in the gaps of the telescopic cover or the grooves of the guide rail. The direct intervention of the auxiliary centrifugal pump 351 can specifically clean such stubborn chips, avoiding the decrease in machine tool accuracy or failure caused by chip accumulation.

[0026] Specifically, a connecting seat 361 is provided at the top of the chip removal pipe 36 and the side wall of the suction hood 33.

[0027] In this embodiment, the connector 361 serves as a fixed interface between the chip removal pipe 36 and the suction hood 33, and the two are firmly connected by bolts, which effectively reduces the risk of the chip removal pipe 36 loosening or falling off due to vibration or airflow impact, and ensures the long-term stable operation of the chip suction system. The connector 361 provides a standardized interface, making the installation and disassembly of the chip removal pipe 36 more convenient. The design of the connector 361 can ensure the sealing between the chip removal pipe 36 and the suction hood 33, preventing chips or coolant from leaking at the connection.

[0028] Specifically, the mounting plate 31 is located below the retracted cover plate 22.

[0029] In this embodiment, the position below the mounting plate 31 makes it closer to the chip generation area. The chip suction component 3 can directly perform negative pressure adsorption on the chip accumulation point through the inverted trapezoidal adsorption mask 32 and suction pipe 312 on the mounting plate 31, reducing the residue of chips in the telescopic cover gap or guide rail, and significantly improving the chip suction efficiency.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
