Description

Technical Field

[0001] The invention relates to the technical field of machine tools, in particular to a fully automatic horizontal machining center. Background Art

[0002] CNC machine tools are short for Computer numerical control machine tools, which are automated machine tools equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing. The machining center is a highly automated multifunctional CNC machine tool with a tool magazine and an automatic tool changer.

[0003] As an important equipment in modern manufacturing, horizontal machining centers are widely used in many fields such as automobiles, aerospace, and mold manufacturing. However, traditional horizontal machining centers still have some limitations in terms of machining efficiency and precision maintenance.

[0004] As a key component of the horizontal machining center, the cradle carries the workpiece and realizes its rotational motion, playing a vital role in milling, turning, grinding and other processing processes. However, the traditional cradle has many shortcomings in displacement accuracy, stability and wear resistance. With the continuous improvement of the manufacturing industry's requirements for processing accuracy and efficiency, the machine tool cradle in the existing technology has been unable to meet the needs of high-precision and high-stability processing.

[0005] First of all, in terms of precision, the traditional cradle can not only be flipped under the drive of the flip motor, but also has a rotation drive system in the middle of the cradle body, which can be rotated horizontally to adjust the processing position of the workpiece on the cradle. This mechanism makes the cradle larger in size and heavier in weight. When flipping, it has a certain inertia. The cradle may produce large errors during the rotation process, thereby affecting the processing accuracy of the workpiece.

[0006] Secondly, stability is also a problem in traditional cradle design. Under high-speed rotation or heavy load conditions, the cradle may vibrate or deform, which will not only affect the processing accuracy, but also may cause damage to other parts of the machine tool.

[0007] In addition, severe wear is also a common problem in traditional cradle designs. Since the cradle needs to withstand large loads and friction during operation, its surface and internal components are easily worn, resulting in performance degradation and even the need for frequent replacement.

[0008] In addition, the horizontal machining center uses cutting oil or coolant during operation. If these liquids remain on the surface of the guide rail, they will mix with dust to form sludge, which increases the friction of the guide rail. Therefore, the horizontal machining center of the prior art manually cleans the sludge on the guide rail regularly. When cleaning, the staff uses a clean rag or paper towel to dip in an appropriate amount of detergent, gently wipe the surface of the guide rail, and remove oil stains and coolant. After wiping, the surface of the guide rail should be wiped dry with a clean dry cloth. The prior art uses manual regular cleaning, which is not only troublesome to operate, but more importantly, the sludge cannot be cleaned in time, causing wear to the guide rail. Minor wear may be manifested as a decrease in surface gloss or small scratches, while severe wear may cause obvious depressions or grooves on the surface of the guide rail, which will affect the rapid movement and accurate positioning of the feed system. Summary of the invention

[0009] In order to solve the above problems, the object of the present invention is to provide a fully automatic horizontal machining center which can improve machining accuracy and stability.

[0019] Furthermore, the power of the spindle drive box is 22.4KW, and the spindle speed is as high as 24000rpm.

[0020] The beneficial effects of the present invention are: The cradle of the present application has a grid-like frame structure design and the horizontal rotation system of the cradle is removed, which greatly reduces the weight of the cradle itself, reduces the moving inertia, and improves the displacement accuracy of the cradle, thereby improving the processing accuracy and stability of the machining center.

The cradle 3 includes a grid-shaped upper frame plate 27 and a grid-shaped lower frame plate 28, and a plurality of vertical connecting rods 29 are arranged between the grid-shaped upper frame plate 27 and the grid-shaped lower frame plate 28. An anti-wear pad 40 is provided on the surface of the grid-shaped upper frame plate 27, and the anti-wear pad 40 is fixed to the grid-shaped upper frame plate 27 by fastening screws 41. The anti-wear pad 40 is usually installed at a position prone to wear of the cradle 3, and can be replaced when the anti-wear pad 40 is worn, without replacing the cradle 3. This solves the problem of frequent replacement of the cradle due to the need to withstand large loads and friction during operation, which causes the surface and internal parts of the cradle to be easily worn.

[0031] The left support seat 4 is provided with a laser interferometer 42, which is used to detect the rotation position accuracy of the left support shaft 8 in real time, and the control unit in the servo rotation drive device 6 compensates the rotation position error of the cradle 3 according to the rotation position accuracy. The present application uses the laser interferometer 42 to detect the rotation position accuracy of the left support shaft 8 in real time, so that the servo rotation drive device 6 realizes closed-loop control of real-time compensation of the rotation position error.

[0032] The tool feeding system 2 is provided with three sets, one set of tool feeding system 2 is provided at the front side of the square frame 1 , and two sets of the tool feeding system are provided at the rear side of the square frame 1 .

[0033] The tool feeding system 2 includes an X-axis moving frame 10, a Y-axis moving frame 11, a bearing beam 24, a counterweight 25, a horizontal steering device 12, a steering beam 13, a bidirectional output servo motor 14, a positive helical screw 15, a reverse helical screw 16, a double slide rail 17, a spindle drive box 18 and a counterweight slide 19. The spindle end of the spindle drive box 18 is used to clamp the tool. The X-axis moving frame 10 is installed on the X-axis slide rail 20 located on the square frame 1 and is driven by the X-axis linear motor 21 on the square frame 1.

The horizontal steering device 12 is installed at the other end of the bearing beam 24. The beam 13 is installed on the horizontal steering device 12, and the horizontal steering device 12 is used to drive the steering beam to steer so as to adjust the inclination angle of the steering beam 13 in the horizontal direction.

The counterweight slide 19 is installed on the double slide rails 17 and is located on the other side of the bidirectional output servo motor 14.

The present application adopts a counterweight to avoid the problem of deformation of the guide rail or the components of the horizontal steering device 12 due to repeated offset of the center of gravity. In particular, a counterweight slide 19 that moves in the opposite direction of the main shaft drive box 18 is adopted, so that the overall center of gravity of the steering beam 13 is always directly above the horizontal steering device 12, so as to solve the problem that the overall center of gravity of the steering beam 13 does not change due to the main shaft drive box 18 being movable, thereby causing the overall center of gravity of the steering beam 13 to deviate from the horizontal steering device 12, thereby causing the components of the horizontal steering device 12 to be deformed.
