Description

Technical Field

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

[0002] A CNC machine tool, short for Computer Numerical Control Machine Tools, is an automated machine tool equipped with a program-controlled system. This control system logically processes programs specified by control codes or other symbolic instructions, decodes them, and transmits them to a coded digital representation via an information carrier. After processing, the CNC device issues various control signals, controlling the machine's movements and automatically producing parts to the shape and size specified in the drawings. A machining center, on the other hand, is a highly automated, multifunctional CNC machine tool equipped with a tool magazine and 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 a horizontal machining center, the cradle supports the workpiece and enables its rotational motion, playing a vital role in milling, turning, grinding, and other machining processes. However, traditional cradles have numerous deficiencies in displacement accuracy, stability, and wear resistance. As the manufacturing industry continues to demand higher precision and efficiency, existing machine tool cradles are no longer able to meet the demands for high-precision and high-stability machining.

[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 not only affects machining accuracy but may also damage other parts of the machine tool.

[0007] Furthermore, severe wear and tear is a common problem in traditional cradle designs. Because cradles need to withstand large loads and friction during operation, their surfaces and internal components are prone to wear, resulting in performance degradation and even the need for frequent replacement.

[0008] In addition, horizontal machining centers use cutting oil or coolant during operation. If these liquids remain on the surface of the guide rails, they will mix with dust to form sludge, which increases the friction of the guide rails. Therefore, the horizontal machining centers of the prior art manually clean the sludge on the guide rails regularly. When cleaning, the staff uses a clean rag or paper towel dipped in an appropriate amount of detergent to gently wipe the surface of the guide rails to remove oil stains and coolant. After wiping, the surface of the guide rails must 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 rails. Minor wear may manifest as a decrease in surface gloss or small scratches, while severe wear may cause obvious depressions or grooves on the surface of the guide rails, which will affect the rapid movement and accurate positioning of the feed system. Summary of the Invention

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless there is a conflict.

[0038] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper surface", "lower surface", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "forward", "reverse", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0039] like Figure 1 、 2 As shown in Figures 3, 4, 5, and 6, a fully automatic horizontal machining center includes a square frame 1, a tool feeding system 2, a cradle 3, a left support seat 4, a right support seat 5, a servo rotary drive device 6, and a brake device 7. The tool feeding system 2 is arranged on the square frame 1, and the cradle 3 is used to clamp and carry the workpiece to be processed. The left support seat 4 and the right support seat 5 are respectively arranged at the left and right ends of the square frame 1. The left support shaft 8 on the cradle 3 is installed on the left support seat 4 through a bearing, and the right support shaft 9 on the cradle 3 is installed on the right support seat 5 through a bearing. The left support shaft 8 and the right support shaft 9 are installed coaxially. The servo rotary drive device 6 is used to drive the left support shaft 8 to rotate, and the brake device 7 is used to limit the rotation of the right support shaft 5. The cradle 3 is a grid-shaped frame structure made of a light-weight and high-load-bearing material. 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 provided 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 27 and is fixed to the grid-shaped upper frame 27 by fastening screws 41. The anti-wear pad 40 is typically installed at a location on the cradle 3 that is susceptible to wear. When the anti-wear pad 40 is worn, it can be replaced without replacing the cradle 3. This solves the problem of frequent cradle replacements due to the heavy loads and friction that the cradle must withstand during operation, which causes the surface and internal components to wear easily.

[0040] The left support base 4 is provided with a laser interferometer 42 for real-time detection of the rotational position accuracy of the left support shaft 8. The control unit in the servo rotation drive device 6 compensates for the rotational position error of the cradle 3 based on the rotational position accuracy. The present application uses the laser interferometer 42 to detect the rotational position accuracy of the left support shaft 8 in real time, enabling the servo rotation drive device 6 to achieve closed-loop control of real-time compensation for rotational position errors.

[0041] 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 .

[0042] The tool feeding system 2 includes an X-axial moving frame 10, a Y-axial 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-axial moving frame 10 is installed on the X-axial slide rail 20 located on the square frame 1 and is driven by the X-axial linear motor 21 on the square frame 1. The Y-axial moving frame 11 is installed on the Y-axial slide rail 22 located on the X-axial moving frame 10 and is driven by the Y-axial linear motor 23 on the X-axial moving frame 10. The bearing beam 24 is inserted and fixed on the Y-axial moving frame 11. The counterweight 25 is provided at one end of the bearing beam 24. 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 double slide rail 17 is installed on the steering beam 13 and arranged along the length direction of the steering beam 13. The bidirectional output servo motor 14 is arranged in the middle of the steering beam 13 and is located between the double slide rails 17. The spindle drive box 18 is installed on the double slide rails 17 and is located on one side of the bidirectional output servo motor 14. 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 bidirectional output servo motor 14 drives the spindle drive box 18 and the counterweight slide 19 to slide in opposite directions along the double slide rails 17 through the positive helical screw 15 and the reverse helical screw 16 respectively; a rotating shaft locking device 26 is provided on the power output vertical shaft of the horizontal steering device 12, and the rotating shaft locking device 26 is used to limit the rotation of the power output vertical shaft. 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 deviation of the center of gravity. In particular, a counterweight slide 19 that moves synchronously with the main shaft drive box 18 in the opposite direction can ensure 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 and cause deformation of the components of the horizontal steering device 12.

[0043] The tool feeding system 2 further includes a guide rail real-time dust removal and oiling device 30 , and both ends of the X-axial moving frame 10 and the Y-axial moving frame 11 are provided with the guide rail real-time dust removal and oiling device 30 .

An oil guide cotton swab 38 is provided in the oil guide pipe 37. The lubricating oil in the oil storage box 36 is introduced into the guide rail oiling sponge block 35 through the oil guide cotton swab 38. A mounting plate 39 is provided on the dust removal and oiling cover 31 and at one end close to the guide rail oiling sponge block 35. The mounting plate 39 is connected to the X-axis moving frame 10 or the Y-axis moving frame 11 by screws. The device can remove contaminants such as chips, dust, and coolant that fall on the guide rails in real time, and can effectively prevent contaminants from entering between the guide rails and the sliders, greatly reducing the wear of the guide rails, extending the service life of the guide rails, and ensuring the processing accuracy and operational stability of the machining center. At the same time, it also eliminates manual cleaning operations and reduces the maintenance and operating costs of the guide rails.

The X-axis and Y-axis moving frames have a moving speed of up to 120 m / min, and are particularly responsive, with linear accelerations of up to 1 G.
