[0056] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0057] like Figure 1 As shown, a method for manufacturing an integrated bed of a five-axis horizontal machining center with a blade milling mechanism includes:
[0058] Fix the machine bed onto the gantry five-sided machining center;
[0059] The right-angle milling head 1 of the gantry five-sided machining center is used to machine the vertical and horizontal X-axis guide rails 4 at the end of the bed;
[0060] An angle milling head 3 is added to the right-angle milling head 1 of the gantry five-sided machining center, and a horizontal longitudinal Z-axis guide rail 5 is machined on the upper end face of the bed.
[0061] Specifically, the X-axis guide rail 4 and Z-axis guide rail 5 of the five-axis horizontal milling center are machined in one go using the same gantry five-sided machining center to ensure the mutual coordinate accuracy of the two.
[0062] Furthermore, according to the processing requirements, the machine tool spindle BT60 can be converted to BT50 through the conversion sleeve to process the X-axis guide rail 4. The vertical milling cutter can be changed to a horizontal milling cutter through the connecting sleeve 2 and the angle head 3, and the Z-axis guide rail 5 can be machined through the horizontal milling cutter.
[0063] like Figure 2-3 As shown, the present invention also provides a method for inspecting the integrated bed of a five-axis horizontal machining center with a blade milling mechanism, comprising:
[0064] The bed has a horizontal longitudinal Z-axis guide rail 5 at one end and a vertical transverse X-axis guide rail 4 at the other end.
[0065] The leveling ruler 6 is set on the bed frame via the leveling base 13;
[0066] Adjust the leveling base 13 so that the leveling ruler 6 is set horizontally on the bed frame;
[0067] Using the Z-axis guide rail 5 as a reference, align the longitudinal direction of the straightedge 6 so that the longitudinal direction of the straightedge 6 is parallel to the longitudinal direction of the Z-axis guide rail 5.
[0068] Measure the parallelism deviation between the X-axis guide rail 4 and the straightedge 6 in the lateral direction;
[0069] The perpendicularity deviation between Z-axis guide rail 5 and X-axis guide rail 4 is calculated based on the parallelism deviation.
[0070] Specifically, the various end faces of the straightedge 6 are perpendicular to each other. The straightedge 6 is used as a coordinate reference to measure the perpendicularity of the Z-axis guide rail 5 and the X-axis guide rail 4. Before measurement, the straightedge 6 and the bed are level. Then, the horizontal angle of the straightedge 6 is adjusted with the Z-axis guide rail 5 as the reference so that the longitudinal direction of the straightedge 6 is parallel to the longitudinal direction of the Z-axis guide rail 5. Then, the parallelism between the straightedge 6 and the X-axis guide rail 4 is measured. If they are parallel, the X-axis guide rail 4 is perpendicular to the Z-axis guide rail 5. Otherwise, there is a deviation. This deviation can be calculated by the parallelism between the straightedge 6 and the X-axis guide rail 4 and trigonometric functions.
[0071] In this embodiment, it also includes:
[0072] The 6-inch flat foot is made of marble and is T-shaped.
[0073] There are two Z-axis guide rails 5, which are arranged parallel to each other on the bed with a gap between them. One end of the straightedge 6 is located between the two Z-axis guide rails 5.
[0074] There are two X-axis guide rails 4. One X-axis guide rail 4 is located at the lower rear end of the bed, and the other X-axis guide rail 4 is located at intervals on the upper part of the bed through the frame.
[0075] Specifically, by using a T-shaped marble straightedge adapted to the double Z-axis guide rail 5, it can measure both the perpendicularity of the X-axis guide rail 4 and the Z-axis guide rail 5, as well as the parallelism of the two Z-axis guide rails 5.
[0076] Furthermore, the 6-inch ruler can be selected in rectangular, L-shaped, T-shaped, etc., as needed.
[0077] In this embodiment, the longitudinal direction of aligning the straightedge 6 with the Z-axis guide rail 5 as a reference includes:
[0078] The Z-axis guide rail 5 is groove-shaped, including a flat bottom and a vertical wall perpendicular to the flat bottom;
[0079] The X-axis guide rail 4 is groove-shaped, including a vertical bottom and a flat wall perpendicular to the vertical bottom;
[0080] Place the first pusher of the first dial indicator 7 onto the Z-axis guide rail 5, so that one end of the first pusher is in contact with the vertical wall near the side of the flat ruler 6.
[0081] Move the first push gauge and the first dial indicator 7 along the Z-axis guide rail 5, and adjust the leveling ruler 6 according to the reading of the first dial indicator 7 until the longitudinal direction of the leveling ruler 6 is parallel to the longitudinal direction of the Z-axis guide rail 5.
[0082] Specifically, the longitudinal (width direction) of the straightedge 6 is aligned by sliding the first dial indicator 7. The flat bottom and vertical wall, as well as the vertical bottom and flat wall, are used to provide a reference benchmark. The specific groove cross-section can be rectangular, right-angled trapezoidal, or semi-open L-shaped.
[0083] In this embodiment, measuring the parallelism deviation between the lateral side of the X-axis guide rail 4 and the lateral side of the straightedge 6 includes:
[0084] Place the second pusher of the second dial indicator 8 onto the X-axis guide rail 4, so that one end of the second pusher is in contact with the flat wall near the side of the flat ruler 6.
[0085] Move the second push gauge and the second dial gauge 8 along the X-axis guide rail 4, and observe and record the changes in the reading of the second dial gauge 8;
[0086] The perpendicularity of the X-axis guide rail 4 and the Z-axis guide rail 5 is determined based on the fluctuation of the second dial indicator 8.
[0087] Specifically, the deviation between the longitudinal direction (length direction) of the straight ruler 6 and the X-axis guide rail 4 is measured by sliding the second dial indicator 8. Since the longitudinal and transverse directions of the straight ruler 6 are perpendicular to each other, this deviation is the deviation between the Z-axis guide rail 5 and the X-axis guide rail 4.
[0088] like Figure 4 As shown, in this embodiment, assembly inspection is also included, which includes:
[0089] Connect the slide block 12 to the Z-axis guide rail 5;
[0090] Place the fourth dial indicator 10 onto the slide block 12, and connect the head of the fourth dial indicator 10 to the longitudinal side wall of the straightedge 6.
[0091] Slide the slide block 12 along the Z-axis guide rail 5 and observe the fluctuation of the fourth dial indicator 10;
[0092] According to the fluctuation of the fourth dial indicator 10, the longitudinal direction of the straightedge 6 is parallel to the longitudinal direction of the Z-axis guide rail 5.
[0093] In this embodiment, it also includes:
[0094] Connect the skateboard 11 to the X-axis guide rail 4;
[0095] Place the third dial indicator 9 onto the slide plate 11, with the dial indicator head of the third dial indicator 9 connected to the lateral side wall of the straightedge 6;
[0096] Slide slide plate 11 along X-axis guide rail 4 and observe the fluctuation of the third dial gauge 9;
[0097] Based on the fluctuations of the third dial indicator 9, the X-axis guide rail 4 base surface is repaired, reprocessed, or assembled and scraped for adjustment.
[0098] Specifically, by replacing the slide plate and worktable with the slide plate 11 and slide block 12, the accuracy of the Z-axis and X-axis movement after the bed, worktable and slide plate are combined in the assembly state is simulated.
[0099] Furthermore, the slide plate 11 has a mounting part near the straightedge 6 for fixing the third dial indicator 9, making it convenient for the third dial indicator 9 to be close to the straightedge 6.
[0100] In this embodiment, the slide 12 is U-shaped.
[0101] Specifically, by using the U-shaped avoidance straightedge 6, the straightedge 6 can be avoided. In the assembled state of the slide block 12 and the slide plate 11, it is not necessary to readjust the straightedge 6. Only the accuracy of the straightedge 6 needs to be checked to perform the accuracy test in the assembled state.
[0102] In this embodiment, adjusting the leveling base 13 to make the leveling ruler 6 horizontally set on the bed includes:
[0103] Multiple leveling bases 13 are installed between the leveling ruler 6 and the bed frame;
[0104] Multiple levels 14 are installed on the upper surface of the straightedge 6;
[0105] Adjust the multiple leveling bases 13 to the level of the leveling ruler 6 using multiple spirit levels 14.
[0106] Specifically, multiple levels 14 are used together to check whether the leveling ruler 6 is level.
[0107] In this embodiment, the leveling base 13 is respectively set at the end and middle of the leveling ruler 6, and the level 14 is set in correspondence with the leveling base 13.
[0108] In this embodiment, the integrated bed inspection method for the five-axis horizontal machining center with impeller milling is used, taking a T-shaped marble straightedge as an example. The main bed of the new product, the five-axis horizontal machining center with impeller milling, is designed as an integrated welded bed with an overall "gantry" frame structure. The entire bed is machined with the transverse X-axis guide rail 4 (slide movement) and the longitudinal Z-axis guide rail 5 (worktable movement), ensuring the verticality of the guide rails is 0.02mm. For finishing, the transverse X-axis guide rail 4 is machined using a right-angle milling head 1 on a gantry five-sided machining center, and the longitudinal Z-axis guide rail 5 is machined using the right-angle milling head 1 through the connecting sleeve 2 / connecting flange and the angle head 3.
[0109] During the inspection, a high-precision electronic level 14 is placed on a special T-shaped marble straightedge and leveled. Then, the longitudinal direction of the T-shaped marble straightedge is aligned with the Z-axis guide rail 5 as the reference, and the transverse direction of the T-shaped marble straightedge is adjusted with the X-axis guide rail 4 as the reference. The verticality of the Z / X guide rails is then checked.
[0110] Connect the special tooling slide 12 to the Z-axis slider, and connect the special tooling slide 11 to the X-axis slider. The slide 11 is combined with the testing push gauge. Move the Z-axis and X-axis respectively, and push the gauge along the T-shaped marble straightedge to test the accuracy. Simulate the detection and adjustment of the perpendicularity accuracy of the Z-axis and X-axis movement after the bed and worktable and slide are combined in the assembly state.
[0111] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
