具体实施方式Detailed ways

以下是本发明的具体实施例并结合附图,对本发明的技术方案作进一步的描述,但本发明并不限于这些实施例。The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

如图1至图4所示,本两箱四轴多功能数控机床包括机架1,在机架1上设置有用于放置工件14的工作台2,其中工作台2由横向滑板3和可在横向滑板3上纵向滑动的纵向滑板4组成。在纵向滑板4上固连有夹具12,在夹具12上开设有安装槽13且工件14放置在安装槽13内,这样可以起到紧固工件14和定位的作用,防止工作在加工时移位,保证加工时的精确性和稳定性。As shown in Figures 1 to 4, the two-box four-axis multifunctional CNC machine tool includes a frame 1, and a workbench 2 for placing a workpiece 14 is arranged on the frame 1, wherein the workbench 2 is composed of a transverse slide plate 3 and can be placed on the frame 1. The vertical slide plate 4 that vertically slides on the horizontal slide plate 3 is formed. A fixture 12 is fixedly connected to the longitudinal slide 4, and a mounting groove 13 is opened on the fixture 12, and the workpiece 14 is placed in the mounting groove 13, which can play the role of fastening the workpiece 14 and positioning, and prevents the work from shifting during processing. , to ensure the accuracy and stability of processing.

在机架1上安装有左右对称设置的第一机座5和第二机座6,在第一机座5上安装有平行设置的第一主轴7和第三主轴9,在第二机座6上安装有与第一主轴7和第三主轴9对称设置的第二主轴8和第四主轴10,也就是说,第一主轴7和第二主轴8处于同一轴心线上,第三主轴9和第四主轴10处于同一轴心线上。主轴平行设置可以降低机床的整体高度,而且还可以专门针对那些需要加工侧面的工件14。第一主轴7和第三主轴通过皮带由第一电机16控制转动,第二主轴8和第四主轴通过皮带由第二电机17控制转动,由一个电机带动安装在同一个机座上的两主轴,既可以减少制造成本,而且还可以减轻设备的整体重量,同时还能保证该两个主轴的同步性。On the frame 1, the first machine base 5 and the second machine base 6 which are symmetrically arranged on the left and right sides are installed, and the first main shaft 7 and the third main shaft 9 which are arranged in parallel are installed on the first machine base 5, and on the second machine base 6 is installed with the second main shaft 8 and the fourth main shaft 10 which are arranged symmetrically with the first main shaft 7 and the third main shaft 9, that is to say, the first main shaft 7 and the second main shaft 8 are on the same axis line, and the third main shaft 9 and the fourth spindle 10 are on the same axis.

The first main shaft 7 and the third main shaft are controlled to rotate by the first motor 16 through the belt, the second main shaft 8 and the fourth main shaft are controlled to rotate by the second motor 17 through the belt, and the two main shafts installed on the same base are driven by one motor , not only can reduce the manufacturing cost, but also can reduce the overall weight of the equipment, and can also ensure the synchronization of the two main shafts.

安装在同一个机座上两主轴的工作头15之间的间距大于工件14的长度,由于安装在同一个机座上两主轴的工作头15是由同一个电机带动的,这样当工件14移动到位并只需要其中一个工作头15对其加工时,由于工件14过长,会出现另一个工作头15也在对该工件14进行加工的情况,因此在使用本机床时,所要加工工件14的长度要小于处于同一侧两工作头15之间的间距。The distance between the working heads 15 of the two main shafts installed on the same support is greater than the length of the workpiece 14. Since the working heads 15 of the two main shafts installed on the same support are driven by the same motor, when the workpiece 14 moves When it is in place and only one of the working heads 15 is required to process it, because the workpiece 14 is too long, another working head 15 will also process the workpiece 14. Therefore, when using this machine tool, the workpiece 14 to be processed The length is less than the spacing between the two working heads 15 on the same side.

在机架1上安装有控制工作台2水平左右位移和水平前后位移的控制机构,控制机构包括固定在机架1上控制横向滑板3滑动的第一气缸18和固定在横向滑板3上控制纵向滑板4滑动的第二气缸19,在机架1上具有横向设置的导轨11且横向滑板3安装在导轨11上。通过第一气缸18控制横向滑板3在机架1导轨11上做横向移动,从而可以将工件14从一侧的工作头15处移动至另一侧的工作头15处进行加工。第二气缸19控制纵向滑板4在横行滑块上做纵向移动,从而可以将工件14从前侧的工作头15处移动至后侧的工作头15处进行加工。A control mechanism is installed on the frame 1 to control the horizontal displacement of the worktable 2 left and right and the horizontal front and rear displacement. The second air cylinder 19 that the slide plate 4 slides has a guide rail 11 arranged transversely on the frame 1 and the transverse slide plate 3 is installed on the guide rail 11 . The first cylinder 18 controls the transverse sliding plate 3 to move laterally on the guide rail 11 of the frame 1, so that the workpiece 14 can be moved from the working head 15 on one side to the working head 15 on the other side for processing. The second cylinder 19 controls the longitudinal sliding plate 4 to move longitudinally on the horizontal slide block, so that the workpiece 14 can be moved from the working head 15 on the front side to the working head 15 on the rear side for processing.

使用本机床加工涂料喷笔时,先将工件14放置在夹具12上的安装槽13内,并将四个不同的工作头15分别放置到四个主轴上;接着电机开启,工作台2在第一气缸18的带动下先移动至第一主轴7工作头15处进行加工;加工完成后,在第一气缸18的带动下反向移动至第二主轴8工作头15处进行加工;加工好后在第一气缸18的带动下工作台2先返回至中间位置,再在第二气缸19的带动下纵向滑板4开始在横向滑板3上滑动;等工件14的待加工面与第三主轴9工作头15处于同一轴心线上时,第二气缸19停止工作,第一气缸18开始工作并带动横向滑板3使工件14移动至加工点处;加工完成后,在第一气缸18的带动下反向移动至第四主轴10工作头15处进行加工,此时工件14即可完成全部加工。When using this machine tool to process the paint spray pen, the workpiece 14 is placed in the mounting groove 13 on the fixture 12, and four different working heads 15 are respectively placed on the four main shafts; Driven by a cylinder 18, it first moves to the working head 15 of the first main shaft 7 for processing; after the processing is completed, it reversely moves to the working head 15 of the second main shaft 8 under the drive of the first cylinder 18 for processing; Driven by the first cylinder 18, the workbench 2 first returns to the middle position, and then the longitudinal slide 4 starts to slide on the horizontal slide 3 under the drive of the second cylinder 19; When the head 15 is on the same axis line, the second cylinder 19 stops working, the first cylinder 18 starts to work and drives the transverse slide plate 3 to move the workpiece 14 to the processing point; Move to the working head 15 of the fourth spindle 10 for processing, and now the workpiece 14 can complete all processing.

本机床工件14一次装夹即可完成全部加工,且确保达到全部技术要求,生产效率比普通单机提高一倍以上,比双头车也要提高50%以上。The workpiece 14 of this machine tool can be fully processed in one clamping, and all technical requirements are guaranteed to be met. The production efficiency is more than double that of a common single machine, and it is also increased by more than 50% than that of a double-headed machine.

在本实施例中,气缸和电机的启动及运转都通过基于PLC的控制柜来控制。In this embodiment, the start-up and operation of the cylinder and the motor are all controlled by a PLC-based control cabinet.
