Detailed ways

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.

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.

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 parallel arrangement of the spindles reduces the overall height of the machine tool and also allows for the specialization of workpieces that require side machining14. 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.

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.

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.

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.

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.

In this embodiment, the start-up and operation of the cylinder and the motor are all controlled by a PLC-based control cabinet.
