Description

Technical Field

[0001] This invention belongs to the field of protective structures for machining centers, specifically relating to an overall wearable protective structure for a moving column machining center and its assembly method. Background Technology

[0002] Moving-column machining centers are widely used for precision machining of large workpieces due to their large machining range and high rigidity. The X-axis travel of these machines is typically over 2 meters, requiring a protective system to prevent chip and coolant splashes and to ensure operator safety.

[0003] In existing technologies, the protective systems of moving-column machining centers mostly adopt a split structure, meaning that after the main machine body is assembled, the sheet metal protective components are installed onto the machine tool one by one. This split assembly has the following drawbacks: 1) The protective assembly and the main machine assembly have a strict sequential order, and they cannot be carried out in parallel, resulting in a long assembly cycle and requiring a significant amount of assembly time, affecting the overall delivery cycle; 2) The split protective frame is assembled from scattered sheet metal parts, resulting in insufficient overall rigidity and easy deformation, which not only makes assembly difficult but also affects the flatness of the machine tool's appearance and the protective effect; 3) During the later assembly process, the protective components are easily contaminated with oil and cutting fluid, affecting cleanliness. Therefore, it is necessary to develop an integrated protective solution that can completely separate the protective assembly from the main machine assembly and has better structural rigidity. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide an integrated wearable protective structure for a moving-column machining center and its assembly method, addressing the shortcomings of existing technologies. This invention enables parallel operation of protective assembly and main machine assembly, shortening the overall assembly cycle. Simultaneously, it allows the protective unit to be integrally formed on the tooling chassis before being hoisted and fitted, improving assembly accuracy and overall rigidity. The protective structure of this invention adopts a "wearable" design, ensuring the aforementioned rigidity and accuracy while achieving the separability of the protective unit from the main machine unit, facilitating independent debugging and subsequent maintenance of the main machine.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an assembly method for an integral wearable protective structure for a moving column machining center, comprising the following steps: (1) Provide a first chassis and a second chassis with the same structure, wherein the first chassis is used as a tooling chassis and the second chassis is used as a finished product chassis; (2) Install the lower bracket assembly on the first chassis to form a tooling chassis frame; (3) Install bracket components and column components on the tooling chassis frame to form a protective frame, and install sheet metal protective parts on the protective frame. Then lift the protective frame with sheet metal protective parts installed from the first chassis to obtain an independently formed overall protective unit. (4) Install the lower bracket assembly on the second chassis to form a finished chassis frame, and then install the main body of the moving column machining center on the finished chassis to form a main unit; (5) Hoist the overall protective unit obtained in step (3) onto the main unit obtained in step (4) and fit it from top to bottom so that the overall protective unit covers the outside of the main unit. (6) Fix the lower part of the overall protective unit to the finished chassis frame to complete the assembly.

[0006] This invention achieves complete separation of protective assembly and main unit assembly by using a first chassis (tooling chassis) and a second chassis (finished product chassis) with identical structures. The overall protective unit is assembled independently on the tooling chassis, and the main unit is assembled independently on the finished product chassis. The two processes can be performed simultaneously without interference. Actual calculations show that compared to traditional split assembly, the assembly cycle of each machine tool can be shortened by several days. Furthermore, because the overall protective unit is not restricted by the main unit structure during assembly, the operating space is larger, and the assembly efficiency is higher.

[0007] Preferably, the lower support assembly in step (2) includes a front lower support, a rear lower support, a left lower support, and a right lower support, which are respectively installed on the front, rear, left, and right sides of the first chassis; the lower support assembly in step (4) includes a front lower support, a rear lower support, a left lower support, and a right lower support, which are respectively installed on the front, rear, left, and right sides of the second chassis. The lower support assemblies are installed on the front, rear, left, and right sides of the first and second chassis respectively, forming a complete support frame, providing an accurate positioning reference for the subsequently installed upper support assembly and column assembly, and ensuring the geometric accuracy of the protective frame; at the same time, the connection method between the lower support assembly and the chassis is simple and reliable, and facilitates quick installation and disassembly.

[0008] Preferably, the upper support assembly in step (3) includes a front upper support, a rear upper support, a left upper support, a right upper support, a left top short support, a right top short support, a front top long support, and a rear top long support; the column assembly includes a left front column, a left rear column, a right front column, a right rear column, and a rear bottom column, which together form a hexahedral frame structure; the front upper support, the left upper support, and the right upper support are respectively installed on the front lower support, the left lower support, and the right lower support, and the rear upper support is installed on the rear bottom column. The rear bottom column is mounted on the rear lower bracket, the left front column and left rear column are mounted on the left upper bracket, the right front column and right rear column are mounted on the right upper bracket, the left top short bracket connects the left front column and left rear column, the right top short bracket connects the right front column and right rear column, the front top long bracket connects the left front column and right front column, and the rear top long bracket connects the left rear column and right rear column. Through the specific connection relationships of the front upper bracket, rear upper bracket, left upper bracket, right upper bracket, and each column, top long bracket, and top short bracket, a hexahedral frame structure is formed. This structure is integrally welded or bolted together, significantly improving overall rigidity compared to traditional split-type splicing. It is less prone to deformation during hoisting and use, and the surface flatness of the sheet metal parts is better after installation. At the same time, the connection relationships between each bracket are clear, eliminating the need for repeated adjustments during assembly, simplifying the assembly process, and facilitating modular design and assembly.

[0009] Preferably, the sheet metal protective components in step (3) include a front guard, left guard, right guard, rear guard, top guard, and a sliding door. The sliding door is located in the middle of the front side of the protective frame. The front guard is located on the left and right sides of the sliding door. The left and right guards are located on the left and right sides of the protective frame, respectively. The rear guard is located on the rear side of the protective frame, and the top guard is located on the upper side of the protective frame. The positions of the front guard, left guard, right guard, rear guard, top guard, and sliding door on the protective frame are clearly defined. The sliding door is located in the middle of the front side, facilitating the entry and exit of operators and the loading and unloading of workpieces. Because the protective frame itself has sufficient rigidity and accurate geometric dimensions, the sheet metal components fit tightly after installation, resulting in a smooth appearance and good sealing.

[0010] Preferably, in step (5), the lifting is performed using eye bolts installed on the protective frame. By installing eye bolts on the protective frame, the entire protective unit is safely and stably lifted. The stress points are reasonably distributed during lifting, avoiding deformation of the protective unit due to uneven stress during the lifting process.

[0011] Preferably, the main body of the moving column machining center is equipped with an electrical cabinet, an oil cooler, a pneumatic control panel, and an operation panel. These components are located outside the outline of the overall protective unit during step (5). The placement of these components outside the overall protective unit ensures that the protective unit is not interfered with when it is fitted onto the main unit from top to bottom, guaranteeing a smooth hoisting process. Furthermore, these external components do not occupy internal space, facilitating daily operation and maintenance.

[0012] A wearable protective structure for a moving-column machining center includes: A finished chassis frame, the finished chassis frame including a finished chassis and a lower support assembly mounted on the finished chassis, the main body of a moving column machining center is mounted on the finished chassis; An independently formed integrated protective unit, comprising a protective frame and sheet metal protective components mounted on the protective frame, with an opening at its lower end; the integrated protective unit covers the outside of the main unit from top to bottom and is fixedly connected to the finished chassis frame, so that the main body is covered inside the integrated protective unit.

[0013] The protective structure of this invention consists of two parts: a prefabricated chassis frame and an independently molded integral protective unit. The integral protective unit is an independently molded structure with an open bottom, fitted from top to bottom onto the outside of the prefabricated chassis frame on which the main body is mounted. This "wearable" structure creates two layers of protection between the integral protective unit and the main body unit, providing excellent protection. Furthermore, the integral protective unit can be completely disassembled, facilitating later maintenance and repair. Because the integral protective unit is separated from the main body unit during assembly, the main body unit can undergo precision adjustments, test cutting of parts, spindle running-in, and tool magazine running-in even before the protective unit is installed, improving the flexibility of equipment debugging.

[0014] Preferably, the lower support assembly includes a front lower support, a rear lower support, a left lower support, and a right lower support, which are respectively installed on the front, rear, left, and right sides of the finished chassis; the protective frame includes an upper support assembly and a column assembly. The upper support assembly includes a front upper support, a rear upper support, a left upper support, a right upper support, a left top short support, a right top short support, a front top long support, and a rear top long support. The column assembly includes a left front column, a left rear column, a right front column, a right rear column, and a rear bottom column, which together form a hexahedral frame structure; the front upper support, the left upper support, and the right upper support are respectively installed on the front, rear, left, and right sides of the chassis. The lower front support, lower left support, and lower right support are mounted on the lower rear support. The upper rear support is mounted on the lower rear column, and the lower rear column is mounted on the lower rear support. The left front column and left rear column are mounted on the upper left support, and the right front column and right rear column are mounted on the upper right support. The left top short support connects the left front column and the left rear column, the right top short support connects the right front column and the right rear column, the front top long support connects the left front column and the right front column, and the rear top long support connects the left rear column and the right rear column. The lower support assembly on the finished chassis frame and the upper support assembly and column assembly on the protective frame form a precise corresponding connection relationship, together constituting a hexahedral frame structure. This structure has good overall rigidity, can remain stable during machine tool operation, is not prone to vibration or deformation, and effectively protects the internal components of the machine tool.

[0015] Preferably, the sheet metal protective components include a front guard, left guard, right guard, rear guard, top guard, and a sliding door. The sliding door is located in the middle of the front side of the protective frame. The front guard is located to the left and right of the sliding door. The left and right guards are located on the left and right sides of the protective frame, respectively. The rear guard is located on the rear side of the protective frame, and the top guard is located on the top side of the protective frame. The layout of the front guard, left guard, right guard, rear guard, top guard, and sliding door on the protective frame is reasonable, with the sliding door located in the middle of the front side for easy operation. Each sheet metal component is installed on a rigid hexahedral frame, making it less prone to loosening or abnormal noise due to vibration. It has a smooth and aesthetically pleasing appearance and a long service life.

[0016] Preferably, the integrated protective unit is equipped with eye bolts; the electrical cabinet, oil cooler, pneumatic control panel, and operation panel on the main body are located outside the outline of the integrated protective unit. The eye bolts on the integrated protective unit facilitate overall hoisting and disassembly. The location of the electrical cabinet, oil cooler, pneumatic control panel, and operation panel outside the outline of the integrated protective unit not only avoids hoisting interference but also ensures good heat dissipation for these components during machine operation. The operation panel facilitates observation and operation, improving the overall practicality and ease of maintenance of the machine.

[0017] Compared with the prior art, the present invention has the following advantages: 1. The method of this invention achieves complete separation between protective assembly and main unit assembly. The overall protective unit is assembled independently on the tooling chassis, and the main unit is assembled independently on the finished product chassis. The two processes can be carried out simultaneously without interference. Actual calculations show that compared with traditional split assembly, the assembly cycle of each machine tool can be shortened by about 3 days, accounting for 30% of the total assembly time of the whole machine. At the same time, since the overall protective unit is not restricted by the main unit structure during assembly, the operating space is larger and the assembly efficiency is higher.

[0018] 2. The protective structure of this invention consists of two parts: a finished chassis frame and an independently molded integrated protective unit. The "wearable" structure of the integrated protective unit creates two layers, inner and outer, between the integrated protective unit and the main unit, resulting in excellent protection. Furthermore, the integrated protective unit can be completely disassembled, facilitating later maintenance and repair. Because the integrated protective unit is separated from the main unit during assembly, the main unit can perform precision adjustments, part trial cutting, spindle running-in, and tool magazine running-in before the protective unit is installed, improving the flexibility of equipment debugging.
