Description

Technical Field

[0001] The utility model relates to the field of machine tool structures, in particular to a multi-head machining center. Background Art

[0002] The multi-head machine of the crossbeam generally does not use an integral X-slide plate because of the large number of machine heads. Instead, it is connected by connecting multiple X-slide plates to each other. Currently, the connection is fixed by locking the slide plate connecting block on the front of two or more X-slide plates. In this method, when the mounting surface used to install the slide plate connecting block is not accurate enough, there will be an error between the connecting surfaces of the two X-slide plates. After the two are fastened with the slide plate connecting block, the state between the two X-slide plates is fixed. When the machine head is installed on the X-slide plate and the machine head is used for processing, the error of the X-slide plate will affect the subsequent installation and subsequent processing of the machine head.

[0003] Therefore, this X-slide connection method requires high dimensional accuracy and assembly accuracy of the mounting surface for mounting the slide connection block 200. Figure 1 For example, when assembling two x slides, the precision of the first slide mounting surface 300 and the second slide mounting surface 400 for mounting the slide connecting block 100 is required to be high, otherwise during assembly, the first slide mounting surface 300 and the second slide mounting surface 400 will appear one high and one low, and when the slide connecting block 200 is assembled on the two mounting surfaces (the first slide mounting surface 300 and the second slide mounting surface 400), assembly errors will occur. In order to ensure that the two X slides meet the coplanarity requirement, it is generally necessary to scrape the first slide mounting surface 300 and the second slide mounting surface 400 in the manufacturing stage, and high precision means increased processing costs, which will generate more man-hours, increasing the overall cost.

[0004] Based on the above, the prior art still has deficiencies and needs to be improved. Utility Model Content

[0039] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0040] refer to Figures 2 to 6The utility model provides a multi-head machining center, including: a bed, a crossbeam 6 is arranged on the bed, a slide assembly is arranged on the crossbeam 6, the slide assembly is connected by a connecting block assembly, a machine head can be installed on each slide, and the connection of multiple slides can realize the processing of multiple machine heads. Specifically, the slide assembly includes a first slide 1 and a second slide 2, the connecting block includes a first connecting block 3 and a second connecting block 4, the first slide includes a first side close to the second slide, and a first mounting position 11 that is sunken and crosses the side of the first slide 1 is opened on the first side of the first slide 1, that is, the first mounting position 11 is from the orthographic projection direction of the first slide 1 (reference Figure 3 direction) passes through the first skateboard 1; the second skateboard includes a second side edge close to the first side edge, the second mounting position 22 is a concave notch opened along the edge line of the side edge of the second skateboard 2, the second mounting position 22 is a notch that does not pass through the second skateboard 2, the concave notch has at least one fastening connection surface, and the direction faced by the fastening connection surface is consistent with the thickness direction of the second skateboard. A virtual XYZ coordinate system is established on the skateboard, and the second connecting block is provided with a first fastening surface and a second fastening surface on one end face in the thickness direction (Y-axis direction) of the first skateboard, and the first connecting block 3 can be installed on the first mounting position 11 movably in the Y-axis direction, and when the first skateboard 1 is connected to the second skateboard 2, the first fastening surface 41 of the second connecting block 4 is connected to the second mounting position 22, and the second fastening surface 42 of the second connecting block 4 is connected to the first connecting block 3, and the first connecting block 3 and the second connecting block 4 are in a vertical state.

[0041] When the first slide 1 and the second slide 2 are assembled, the first connection block 3 is installed in the first installation position 11. At this time, the fastening hole on the first connection block 3 is aligned with the fastening hole on the first installation position 11, and then the fastener is inserted into the holes of both. At this time, the connection between the first connection block 3 and the first installation position 11 is first in a pre-tightened state. Since the diameter of the fastener is slightly smaller than the fastening hole, the fastener has a certain amount of space to move in the fastening hole in the pre-tightened state. When the first connection block 3 and the first slide 1 are in the pre-tightened state, the first connection block 3 can be fine-tuned to a certain extent on the first installation position 11 until the first connection block 3 is adjusted to a position that meets the requirements or is required. For example, a force in the Y-axis direction is applied to the first connecting block 3 so that the first connecting block 3 can move along the Y-axis direction. When the position of the first connecting block 3 is adjusted to meet the requirements, the first fastening surface 41 of the second connecting block 4 is connected to the second mounting position 22, and the second fastening surface 42 of the second connecting block 4 is connected to the first connecting block 3. The first fastening surface 41 and the second fastening surface 42 are located on the same surface of the second connecting block 4. The utility model makes the first connecting block 3 adjustable relative to the first mounting position 11, thereby making the coplanarity of the second connecting block 4 and the ZX planes of the first and second slide plates 1 and 2 adjustable. The position of the first connecting block 3, which is equivalent to the first slide plate 1, is adjustable, which reduces the difficulty of processing parts such as slide plates and connecting blocks and reduces the difficulty of assembly in the manufacturing stage, ultimately achieving cost reduction and efficiency improvement.

[0042] In one embodiment, reference Figures 2 to 6 To facilitate the installation of the connecting block, the first installation position 11 is set at the corner of the first slide plate 1, that is, a sunken installation position is opened at the intersection of the side surface and the end surface of the first slide plate 1, from the positive projection direction of the first slide plate 1 ( Figure 3 The first mounting position 11 is a reverse "L"-shaped structure when viewed from the Y-axis direction of the first slide 1. Since the first mounting position 11 passes through the side of the first slide 1, the first mounting position 11 has two surfaces, including a first bottom surface 12 and a first side surface 13. The first mounting position 11 cooperates with the second mounting position 22, so the second mounting position 22 is also set at the corner of the second slide 2, and the second mounting position 22 is a notch that does not pass through the second slide 2, so the second mounting position 22 has three surfaces, including a bottom surface and two side surfaces, and the two side surfaces correspond to the ZX side surface and the ZY side surface.

The upper end faces of the entire slide plate are coplanar, so that the upper end of the slide plate is a straight line when viewed from the orthographic projection direction of the slide plate. The coplanarity of the upper end faces of the slide plate avoids the first connecting block 3 and the second connecting block 4 from protruding along the end face of the slide plate, thereby avoiding the protruding parts from interfering with other structures.

The disassembly hole 15 can be used to disassemble the second connecting block 4. For example, when the second connecting block 4 needs to be disassembled, a slender strip tool is inserted into the disassembly hole 15, and then the second connecting block 4 is taken out of the mounting groove.

[0047] In one embodiment, reference Figure 3 , Figure 5 and Figure 7, the first bottom surface 12 is a surface perpendicular to the height direction of the first slide plate 1, i.e., the XY surface; the first side surface 13 is a surface perpendicular to the length direction of the first slide plate 1, i.e., the ZY surface; a first fastening hole 14 is provided on the first side surface 13. The first connecting block 1 includes a first connecting surface 31 and a second connecting surface 32 perpendicular to the first connecting surface 31, a through second fastening hole 33 is provided on the first connecting surface 31, and a third fastening hole 34 is provided on the second connecting surface 32.

The second connecting block 4 is installed in the mounting groove, the fifth fastening hole 43 is aligned with the fourth fastening hole 26, the sixth fastening hole 44 is aligned with the third fastening hole 34, and a fastener is inserted into the fifth fastening hole 43 and the fourth fastening hole 26, and the fastener is inserted into the sixth fastening hole 44 and the third fastening hole 34, so that the second connecting block 4 is fastened in the mounting groove.

[0049] In one embodiment, reference Figure 3 and Figure 4 The first slide 1 and the second slide 2 are both provided with a head position 5 for installing the head. The head position 5 is a guide groove set on the slide. The connecting blocks are all located on the side of the slide where the head position 5 is set, which is convenient for adjusting the connecting blocks and observing the connection blocks and the slides.

[0050] In one embodiment, reference Figure 3 and Figure 4 The connecting block, the first mounting position 11 and the second mounting position 22 are all set to two symmetrically about the midline of the length direction of the slide plate, so that the upper and lower (with Figure 4As a reference, connecting blocks are arranged at both ends of the first slide 1 and the second slide 2 for connecting.
