Description

A four-spindle structure of a CNC machine tool

technical field

The utility model relates to a numerical control machine tool, more specifically a four-spindle structure of the numerical control machine tool.

Background technique

The spindle of the CNC machine tool has always been an important part of the CNC machine tool. The CNC machine tool drives the rotation of the spindle through the motor, and then drives the tool on the spindle to process the workpiece. The quality of the spindle will affect the machining accuracy of the CNC machine tool; the rotation speed of the spindle will affect the processing speed of the CNC machine tool. The quality of the spindle and the number of spindles have a great influence on the entire CNC machine tool.

Most of the existing CNC machine tool spindles have a single-spindle structure. The single-spindle structure is simple and easy to operate, but the processing speed is not fast enough, the profit cannot be maximized, and it is difficult to reduce the cost of the enterprise.

Utility model content

The main purpose of the utility model is a four-spindle structure of a CNC machine tool. Through a unique structural design, four identical spindles are linked and processed at the same time, and four identical parts can be processed at one time, which greatly improves the processing efficiency. Save processing time and reduce labor costs.

The technical solution adopted by the utility model is: a four-spindle structure of a numerically controlled machine tool, including an X-axis rail, four spindle kits movably mounted on the X-axis rail, and used to drive the four spindle kits on the X-axis The X-axis servo motor that moves on the rail, the four spindle sets are installed on the X-axis rail through a connecting plate, and each spindle set includes a connecting plate installed on the X-axis rail, a connecting plate installed on the connecting plate The Z-axis rail, the spindle mounting part movably mounted on the Z-axis rail, the Z-axis servo motor for driving the spindle mounting part to move on the Z-axis rail, and the spindle installed in the spindle mounting part.

The X-axis rail is installed on the gantry structure, and a workbench is arranged under the gantry structure.

The beneficial effects of the utility model are as follows: the utility model controls four identical spindles to process at the same time through the numerical control system, and can process four identical parts at one time, which greatly improves the processing efficiency, saves processing time, and reduces Labor costs.

detailed description

As shown in Figure 1 and Figure 2, it is a preferred specific implementation example of the present utility model, a four-spindle structure of a CNC machine tool, including an X-axis rail 10, a movably mounted on the X-axis rail 10 Four spindle sets 20 and an X-axis servo motor 30 for driving the four spindle sets 20 to move on the X-axis rail 10, the four spindle sets 20 are installed on the X-axis rail 10 through a connecting plate 21 Each spindle kit 20 includes a connecting plate 21 mounted on the X-axis rail 10, a Z-axis rail 22 mounted on the connecting plate 21, a spindle mounting part 23 movably mounted on the Z-axis rail 22, The Z-axis servo motor 24 used to drive the spindle mounting part 23 to move on the Z-axis rail 22 and the spindle 25 installed in the spindle mounting part 23 .

When the CNC machine tool is working and processing, the CNC system controls the movement of the connecting plate on the X axis, and at the same time, the Z axis servo motor controls the four spindles to move up and down at the same time. The four spindles work at the same time, and the product is processed at the same time. For processing, the movements and working paths of the four spindles are exactly the same. Four identical workpieces can be processed at one time, which greatly improves the processing efficiency.

Further, the X-axis rail 10 is installed on the gantry structure 40 , and a workbench 50 is arranged under the gantry structure 40 .

The four main shaft sleeve assemblies are all the same. When the main shaft is installed on the main shaft sleeve assembly, strict precision adjustments are performed to avoid large errors when the four main shafts move at the same time, and to ensure that the error is minimized.

When the main shaft sleeve assembly is installed on the main shaft sleeve connecting plate, it also undergoes strict precision adjustment to ensure that the four main shaft sleeve assemblies are all on a straight line to reduce machining errors.

The Z-axis servo motors are also four identical motors, which are uniformly controlled by a numerical control system to ensure that the movements of the four Z-axis servo motors are the same.

The utility model controls four identical spindles to process simultaneously through the numerical control system, and can process four identical parts at one time, which greatly improves the processing efficiency, saves processing time, and reduces labor costs.

The embodiments of the utility model and the accompanying drawings are only to show the design concept of the utility model, and the protection scope of the utility model should not be limited to this embodiment.

Can find out that design purpose of the present utility model can be implemented effectively by above narration. The part of the embodiment demonstrates the object of the utility model and implements the functional and structural subject matter, and includes other equivalent replacements.
