Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a spindle feeding mechanism for a flap horizontal machining center with high positioning accuracy, good rigidity, convenient adjustment and low cost. Background Art

[0002] With the development of aerospace, marine engineering, wind power, automobile and other industries, there are more and more large structural parts, and most of them have the characteristics of thin walls, deep grooves, small corners and extremely low metal utilization. In order to improve processing efficiency, high-speed and high-efficiency (HEM-HSM) milling technology is needed. The traditional gantry machine tool vertical processing system, because the workpiece is placed horizontally, although it is convenient to clamp, the large amount of high-temperature chips generated during the processing is difficult to be discharged in time, which is easy to cause secondary thermal deformation and secondary cutting of the workpiece, and it is easy to form built-up edge, which affects the final processing quality of the workpiece and shortens the service life of the tool.

[0003] At present, the horizontal machining center with flip table is a composite CNC machine tool that is a horizontal five-axis machining center supplemented by a flip device. Since the horizontal machining center with flip table can achieve the process purpose of clamping the workpiece in the horizontal position and processing in the vertical position, it combines the advantages of convenient clamping of vertical machine tools and easy chip removal of horizontal machine tools, so it is widely used in the field of large-scale metal processing. The spindle systems of existing flap-type horizontal machining centers mostly adopt the structure of lower or side wall support of guide rails and sliders + rack or lead screw transmission, and the huge spindle system is pressed against the lower support composed of sliders and guide rails by its own weight, or the side support is realized by the sliding cooperation of sliders and guide rails; and in order to arrange the A / C milling head and the feed mechanism, not only the overhang of the A / C milling head and the spindle is long, but also because of the large cutting force and large torque processing characteristics of the flap-type horizontal machining center, and because the spindle system has guide constraints in only one direction, the A / C milling head of the spindle system vibrates when the spindle system is fed at high speed and with large cutting volume, which not only affects the shape and dimensional accuracy of the workpiece, but also seriously affects the service life of the tool and causes abnormal wear of the machining center.

[0004] In order to solve the vibration phenomenon of the spindle system of the horizontal machining center with a flap in the prior art, there is a solution that limits the spindle system to only move in the XZ direction, and realizes the Y direction movement through the workbench, thereby shortening the length of the spindle system to avoid the problem of vibration caused by excessive spindle overhang. Although the above solution can basically solve the vibration problem, the Y-direction feed is separated from the XZ-direction feed of the spindle system, resulting in the superposition of the positioning error of the spindle system and the workbench during processing, thereby increasing the difficulty of improving the processing accuracy of the workpiece and the difficulty of assembling and debugging the machining center. To this end, some people also arrange the spindle system in the spindle box, and use sliding guides and inlays arranged on the top and bottom and even on the sides of the spindle system to realize Y-axis movement, so as to suppress the processing chatter phenomenon by guiding and limiting the spindle system in multiple directions; however, since the sliding guides or inlays are fixed in the channel of the spindle box, not only does the spindle system need to be precisely aligned and hoisted when installed, which makes the installation extremely difficult, but the adjustment of the matching clearance between the sliding guides and the inlays requires multiple disassembly and assembly of the spindle system and repair before it can meet the requirements, and the matching accuracy adjustment is relatively cumbersome.

[0047] Working principle and working process of this utility model:

[0048] like Figures 1 to 10As shown, when installing and adjusting the ram assembly 2, first install the servo motor 411 and the screw seat 413 at the corresponding position at the bottom of the ram 21, then set the Y downward guide rail 22 and the Y upward guide rail 23 in the square grooves 211 at the bottom and top of the ram 21 respectively, and fix the Y downward guide rail 22 and the Y upward guide rail 23 to the ram 21 with screws IV and fixing blocks 9 to complete the installation of the ram assembly 2. At the same time, the Y downward slider 5 is fixedly installed at the positions near the four corners of the bottom surface of the square channel 101, and the screws III on the inclined wedge block I7 are adjusted to tighten the Y downward slider 5; the top of the upper slider 61 is connected to the bottom of the support body 62 by screws to form the Y upward slider 6, and then the upper slider 61 is slid downward from the support channel 102. Then, the slide assembly 2 is installed into the square channel 101, and the Y downward guide rail 22 and the Y downward slider 5 are matched with each other, and the Y upward guide rail 23 and the upper slider 61 are matched with each other. Finally, the support body 62 is fixedly connected to the support box 1 by screw I, and then the matching clearance between the Y upward guide rail 23 and the upper slider 61 is adjusted by adjusting screw I, so that the slide 21 can move flexibly along the Y direction and have a smaller clearance, thereby completing the installation and debugging of the slide assembly 2.

[0049] During operation, the control system controls the servo motor 411 to start, driving the screw 412 to rotate. Driven by the screw nut (i.e., the driving end 42), the ram 21 moves forward and backward along the Y direction to realize the Y-direction feeding of the A / C swing head 3. After working for a certain period of time, the matching clearance increases due to the friction between the guide rail and the slider on the ram 21. The matching clearance between the Y-upward guide rail 23 and the upper slider 61 can be adjusted by adjusting the screw I, so that the moving guide accuracy of the ram 21 can be quickly restored.

[0050] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
