Description

Technical Field

[0001] The present application relates to the technical field of machine tool equipment, and more specifically, to a multi-head parallel machine tool. Background Art

[0002] At present, traditional vertical machine tools generally use one machine head and one machining table to machine workpieces, and their work efficiency is low. If the number of vertical machine tools is increased to achieve higher machining efficiency of the workpiece, on the one hand, the equipment cost of the vertical machine tools will increase, and on the other hand, multiple vertical machine tools will need to occupy factory space.

[0003] For example, application number 202310345169.X discloses a vertical multi-head parallel drilling machine tool, which specifically discloses that multiple drilling heads and multiple drilling tables share the same set of machine tool bases and transverse slide rails. The machine tool has a high degree of integration and reduces the overall drilling cost.

[0004] At least one of its defects is that the three hole-making heads are arranged in sequence along the horizontal direction, and a certain gap space needs to be reserved between two adjacent hole-making heads. This causes the vertical machine tool to increase in the horizontal direction, increasing the floor area of ​​the vertical machine tool, and further causing the vertical machine tool to occupy a larger factory space.

[0005] Therefore, the existing technology needs to be improved. Utility Model Content

[0039] See also Figure 1 This embodiment provides a multi-head 200 parallel machine tool, which includes a machine frame 100, a plurality of machine heads 200 and a plurality of slide rail groups 300. The plurality of machine heads 200 are movably arranged on the machine frame 100 in sequence. The slide rail groups 300 are arranged on the machine frame 100 along the X direction, and two adjacent slide rail groups 300 are arranged as a staggered structure 400. The slide rail groups 300 are used to connect the machine heads 200 and the machine frame 100 to realize a sliding connection between the machine heads 200 and the machine frame 100.

[0040] In this embodiment, the multi-head 200 parallel machine tool includes a machine frame 100 and a plurality of machine heads 200, wherein a corresponding workbench is provided below the machine heads 200, and the machine heads 200 can move laterally in the horizontal direction and move up and down in the vertical direction, and the workbench can move back and forth in the horizontal direction. For example, an X-direction moving mechanism is provided on the machine frame 100, a Z-direction moving mechanism is provided on the X-direction moving mechanism, the machine heads 200 are connected and provided on the Z-direction moving mechanism, and a Y-direction moving mechanism is provided on the side of the machine frame 100 close to the machine heads 200, and a workbench is provided on the Y-direction moving mechanism. The X-direction moving mechanism includes an X-direction drive assembly and a slide rail group 300 that can move along the X-direction, and the X-direction drive assembly is used to drive the machine heads 200 to move along the slide rail group 300, that is, the X-direction drive assembly is used to drive the machine heads 200 to move along the X-direction, which is equivalent to the X-direction drive assembly being able to drive the machine heads 200 to move laterally in the horizontal direction.

[0041] See also Figure 2 In the prior art, the slide rail groups 300 along the X-direction on the machine head 200 are distributed in a straight line in sequence. Therefore, in order to avoid mutual interference among the machine heads 200, for example, the X-direction drive assembly of the machine head 200 needs to occupy a certain size of space, and a certain slide rail gap 330 needs to be reserved between two adjacent machine heads 200 to ensure that each machine head 200 can operate normally.

[0042] See also Figure 3 , Figure 3 The schematic diagram of the structure of the slide rail group 300 provided in this embodiment shows that two adjacent slide rail groups 300 are arranged in a staggered structure 400. Through the staggered design of the two adjacent slide rail groups 300, the two adjacent heads 200 are compactly distributed to reduce the slide rail gap 330 between the two adjacent heads 200. For example, Figure 3 The dashed line represents the length of the slide rail assembly 300 of the machine gantry 100 along the X-direction without the staggered structure 400. The machine heads 200 can move horizontally along the slide rail assembly 300. Due to the staggered design of two adjacent slide rail assemblies 300, the initial heights of the two adjacent machine heads 200 may be inconsistent. However, the initial heights of the machine heads 200 can be adjusted by the Z-direction movement mechanism. That is, through adjustment of the Z-direction movement mechanism, the initial heights of the machine heads 200 can be made consistent. In other words, the staggered design of the two adjacent slide rail assemblies 300 does not affect the X-direction and Z-direction movement of the machine heads 200. In addition, the staggered structure 400 can make the adjacent machine heads 200 compactly distributed, reducing the length of the machine gantry 100 along the X-direction.

[0043] Therefore, in this embodiment, several heads 200 can process multiple workpieces simultaneously, with high processing efficiency, which can reduce processing costs, and two adjacent slide rail groups 300 are set as a staggered structure 400 to reduce the length of the machine frame 100 along the X direction.

[0044] Specifically, see Figure 4 The staggered structure 400 includes a staggered portion 410 and an overlapping extension portion 420 connected to the staggered portion 410 .

[0045] In this embodiment, the staggered structure 400 includes a staggered portion 410 and an overlapping extension portion 420. The overlapping extension portion 420 refers to the overlapping state of two adjacent rail assemblies 300, that is, one rail assembly 300 can extend into the other rail assembly 300 to form a overlapping structure. This makes the two adjacent rail assemblies 300 more compact, further reducing the length of the machine frame 100 along the X direction. For example, Figure 4 The dashed line represents the length of the slide rail assembly 300 of the machine gantry 100 along the X-direction without the overlapping extension portion 420. For example, the machine gantry 100 is provided with multiple machine heads 200, all of which are used to process the same workpiece. Thus, the motion paths of the multiple machine heads 200 during processing can be consistent. This means that when one machine head 200 moves to the left, the adjacent machine head 200 also moves to the left; and when one machine head 200 moves to the right, the adjacent machine head 200 also moves to the right. Therefore, even if two adjacent slide rail assemblies 300 partially overlap, this will not cause interference between the two adjacent machine heads 200.

[0046] Specifically, please combine Figure 3 The slide rail group 300 includes a first group of slide rails 301 and a second group of slide rails 302. The first group of slide rails 301 and the second group of slide rails 302 are staggered and connected to form a staggered structure 400, and the first group of slide rails 301 and the second group of slide rails 302 are partially staggered and overlapped to form an overlapping extension portion 420.

[0047] In this embodiment, the slide rail group 300 includes a first group of slide rails 301 and a second group of slide rails 302. Correspondingly, the machine head 200 includes a first head 210 and a second head 220, which is equivalent to that the machine frame 100 is provided with two heads 200, the first head 210 is connected to the Z-direction moving mechanism, and the Z-direction moving mechanism is slidably connected to the first group of slide rails 301, and the second head 220 is connected to another Z-direction moving mechanism, and the other Z-direction moving mechanism is slidably connected to the second group of slide rails 302, and the first group of slide rails 301 and the second group of slide rails 302 are partially staggered and overlapped to form an overlapping extension portion 420, so that the first group of slide rails 301 and the second group of slide rails 302 are distributed more compactly, further reducing the length of the machine frame 100 along the X direction.

[0048] Specifically, see Figure 1 and Figure 3The slide rail group 300 also includes a third group of slide rails 303. The second group of slide rails 302 and the third group of slide rails 303 are staggered and connected to form a staggered structure 400, and the second group of slide rails 302 and the third group of slide rails 303 are partially staggered and overlapped to form an overlapping extension portion 420, and the third group of slide rails 303 is arranged on the extension line of the first group of slide rails 301 along the X direction.

[0049] In this embodiment, the third group of slide rails 303 is arranged on the extension line of the first group of slide rails 301 along the X direction, which is equivalent to the third group of slide rails 303 having the same height as the first group of slide rails 301, wherein one end of the second group of slide rails 302 can be staggered and stacked with the first group of slide rails 301 to form an overlapping extension portion 420, and the other end of the second group of slide rails 302 can be staggered and stacked with the third group of slide rails 303 to form an overlapping extension portion 420, so that the first group of slide rails 301, the second group of slide rails 302 and the third group of slide rails 303 are distributed more compactly, further reducing the length of the machine frame 100 along the X direction.

[0050] Specifically, see Figure 1 The multi-head 200 parallel machine tool also includes an X-direction tank chain 500, which is connected to the head 200, and the X-direction tank chains 500 of two adjacent heads 200 are set as a staggered structure 400.

[0051] In this embodiment, the machine head 200 is connected with an X-direction tank chain 500. One machine head 200 is correspondingly connected with one X-direction tank chain 500. The X-direction tank chain 500 also occupies a certain size space in the X direction. The X-direction tank chains 500 of two adjacent machine heads 200 are set as a staggered structure 400, so that the two adjacent X-direction tank chains 500 are compactly distributed.

[0052] Specifically, see Figure 1 The X-direction tank chain 500 includes a first tank chain 510, a second tank chain 520 and a third tank chain 530; the machine head 200 includes a first machine head 210, a second machine head 220 and a third machine head 230, and the first machine head 210, the second machine head 220 and the third machine head 230 are sequentially arranged on the machine frame 100 along the X-direction; the first tank chain 510 is connected to the first machine head 210, the second tank chain 520 is connected to the second machine head 220, and the third tank chain 530 is connected to the third machine head 230. The first tank chain 510 and the second tank chain 520 are arranged in a staggered structure 400, and the second tank chain 520 and the third tank chain 530 are arranged in a staggered structure 400.

[0053] In this embodiment, the first tank chain 510 and the second tank chain 520 form a staggered structure 400, and the second tank chain 520 and the third tank chain 530 form a staggered structure 400, so that the three X-direction tank chains 500 are more compactly distributed in the X direction.

[0054] Specifically, see Figure 1 A machine head 200 is provided on the front side of the machine frame 100, and a chain slot group 540 is provided on the top of the machine frame 100. The chain slot group 540 is used to install the X-direction tank chain 500. The chain slot group 540 includes a front chain slot 541 and a rear chain slot 542. The front chain slot 541 and the rear chain slot 542 are arranged in a parallel structure. The first tank chain 510 is installed at the left end of the front chain slot 541, the third tank chain 530 is installed at the right end of the front chain slot 541, and the second tank chain 520 is installed at the rear chain slot 542.

[0055] In this embodiment, the first tank chain 510 and the third tank chain 530 are both arranged in the front chain groove 541, and the second tank chain 520 is arranged in the rear chain groove 542. The second tank chain 520 is located between the first tank chain 510 and the third tank chain 530. In this way, the second tank chain 520 will not interfere with the first tank chain 510, and the second tank chain 520 will not interfere with the third tank chain 530. In addition, there will be a certain distance between the first tank chain 510 and the third tank chain 530, and there will be no interference between the first tank chain 510 and the third tank chain 530. As a result, the distribution of the first tank chain 510, the second tank chain 520 and the third tank chain 530 is more compact.

[0056] Specifically, see Figure 1 , the installation height of the rear side chain slot 542 is higher than the installation height of the front side chain slot 541.

[0057] In this embodiment, the installation height of the rear chain groove 542 is higher than the installation height of the front chain groove 541, which is equivalent to the rear chain groove 542 and the front chain groove 541 forming a staggered structure 400 in the Z direction. This arrangement makes it less likely for the second tank chain 520 to interfere with the first tank chain 510, and makes it less likely for the second tank chain 520 to interfere with the third tank chain 530.

[0058] Specifically, see Figure 5 The slide rail assembly 300 includes an upper slide rail 310 and a lower slide rail 320. The upper slide rail 310 is disposed on the machine frame 100 along the X-axis, and the lower slide rail 320 is disposed on the machine frame 100 along the X-axis, and the lower slide rail 320 is disposed parallel to the upper slide rail 310. The machine head 200 is disposed on a Z-axis moving mechanism, which is slidably connected to the slide rail assembly 300. For example, the upper end of the Z-axis moving mechanism is slidably connected to the upper slide rail 310, and the lower end of the Z-axis moving mechanism is slidably connected to the lower rail 320 to ensure stable sliding.

[0059] Specifically, see Figure 1 and Figure 5The multi-head 200 parallel machine tool also includes a drive motor 600 and a slider 700. The drive motor 600 is connected to the head 200 for driving. The drive motor 600 is used to drive the head 200 to move along the X direction. The slider 700 is fixed to the head 200, and the slider 700 is slidably connected to the slide rail group 300.

[0060] In this embodiment, the drive motor 600 is used to drive the head 200 to move along the X direction, and the slider 700 is fixed to the head 200. For example, the head 200 is connected to a Z-direction moving mechanism, and the Z-direction moving mechanism is provided with a slider 700. The slider 700 is slidably connected to the slide rail group 300 to enable the drive motor 600 to drive the head 200 to slide along the slide rail group 300. For example, the drive motor 600 of the first head 210 is arranged in the first group of slide rails 301, and the drive motor 600 of the first head 210 is located on the left side of the machine frame 100, the drive motor 600 of the third head 230 is arranged in the third group of slide rails 303, and the drive motor 600 of the third head 230 is located on the right side of the machine frame 100, the drive motor 600 of the second head 220 is located in the middle position of the machine frame 100, one end of the second group of slide rails 302 is partially staggered and overlapped with the first group of slide rails 301 to form an overlapping extension portion 420, the other end of the second group of slide rails 302 is partially staggered and overlapped with the third group of slide rails 303 to form an overlapping extension portion 420, and the drive motor 600 of the second head 220 is located in the first group of slide rails 301, with a compact structure and reasonable design.

The plurality of machine heads are movably arranged on the machine frame in sequence, and the slide rail groups are arranged on the machine frame along the X direction, and two adjacent slide rail groups are arranged in a staggered structure.
