Description

Technical Field

[0001] This utility model relates to an economical dual-spindle CNC lathe. Background Technology

[0002] When machining parts on a lathe, the workpiece is typically cut off by a tool on the tool post after the spindle finishes machining, and then the next part is machined. This machining structure is only suitable for parts requiring single-sided machining. If a part requires double-sided machining, it cannot be completed on the same machine tool. Some highly intelligent machines can automatically complete double-sided machining of a single workpiece, but these are expensive, and most small and medium-sized enterprises cannot afford to purchase them. Therefore, designing an economical twin-spindle lathe is essential. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a technical solution for an economical dual-spindle CNC lathe.

[0004] An economical dual-spindle CNC lathe is characterized by comprising a lathe, a main spindle, a sub-spindle, a first tool post, and a second tool post. The main spindle is located on one side of the lathe, and an XY-axis moving mechanism is located on the other side. The sub-spindle and the first tool post are mounted on the XY-axis moving mechanism. The second tool post is mounted above the main spindle via a Z-axis moving plate. A cutting-off tool and a machining tool are mounted on the second tool post. The first tool post, driven by the XY-axis moving mechanism, can move to a position opposite to the main spindle to machine the workpiece on the main spindle. The sub-spindle, driven by the XY-axis moving mechanism, can move to a position opposite to the main spindle to clamp the workpiece on the main spindle. Simultaneously, driven by the Z-axis moving plate, the second tool post cuts off the workpiece clamped on the sub-spindle using the cutting-off tool. Then, driven by the XY-axis moving mechanism, the sub-spindle moves to the right, machining the workpiece using the machining tool on the second tool post.

[0005] The economical dual-spindle CNC lathe is characterized in that the sub-spindle is directly mounted on the XY-axis moving mechanism, and the first tool post is mounted on the XY-axis moving mechanism through a first tool post mounting seat. The sub-spindle and the first tool post are arranged side by side without interfering with each other.

[0006] The economical dual-spindle CNC lathe is characterized in that a vertical plate is provided on the spindle, a cylinder mounting plate is installed on the vertical plate, the cylinder is located above the cylinder mounting plate, a Z-axis moving plate is slidably located below the cylinder mounting plate, the Z-axis moving plate is connected to the output end of the cylinder, and a second tool post is provided on the Z-axis moving plate.

[0007] This invention adds a secondary spindle to the XY-axis moving mechanism of a conventional lathe and a second tool post to the main spindle, enabling double-sided machining of the same workpiece through their cooperation. The first tool post, equipped with a cutting tool, moves to a position opposite to the main spindle under the drive of the XY-axis moving mechanism to machine the workpiece on the main spindle. After machining, the secondary spindle, driven by the XY-axis moving mechanism, moves to a position opposite to the main spindle to clamp the workpiece on the main spindle. Simultaneously, the second tool post, driven by the Z-axis moving plate, cuts off the workpiece clamped on the secondary spindle using a cutting tool. Then, the secondary spindle moves to the right under the drive of the XY-axis moving mechanism, machining the workpiece using a cutting tool on the second tool post. After machining, the secondary spindle releases the workpiece, which falls into a storage box. This process is repeated to achieve double-sided machining of the same workpiece.

Detailed Implementation

[0009] The present invention will be further described below with reference to the accompanying drawings: An economical dual-spindle CNC lathe includes a lathe 1, a main spindle 2, a sub-spindle 4, a first tool post 5, and a second tool post 6. The main spindle 2 is located on one side of the lathe 1. A vertical plate 10 is mounted on the main spindle 2, and a cylinder mounting plate 11 is mounted on the vertical plate 10. A cylinder 12 is located above the cylinder mounting plate 11. A Z-axis moving plate 13 is slidably positioned below the cylinder mounting plate 11 and is connected to the output end of the cylinder 12. The second tool post 6 is mounted on the Z-axis moving plate 13, and a cutting tool 14 and a machining tool 15 are mounted on the second tool post 6 to fulfill different work requirements. The Z-axis moving plate 13 can be mounted on the cylinder mounting plate via a slide rail (not shown in the figure). The sliding structure is existing technology; other methods can also be used, which will not be described in detail here.

[0010] On the other side of the lathe 1, an XY-axis moving mechanism 3 is provided (the XY-axis moving mechanism is existing technology and can be purchased directly, so it will not be described in detail here). The sub-spindle 4 and the first tool post 5 are set on the XY-axis moving mechanism 3. The sub-spindle 4 is directly mounted on the XY-axis moving mechanism 3, and the first tool post 5 is mounted on the XY-axis moving mechanism 3 through the first tool post mounting seat 9. The sub-spindle 4 and the first tool post 5 are set side by side without interfering with each other.

[0011] The first tool post 5 is equipped with a cutting tool. Driven by the XY-axis moving mechanism 3, the first tool post 5 can move to the opposite position of the main spindle 2 to process the workpiece on the main spindle 2. After processing, the sub-spindle 4, driven by the XY-axis moving mechanism 4, can move to the opposite position of the main spindle 2 to clamp the workpiece on the main spindle. At the same time, driven by the Z-axis moving plate 13, the second tool post 6 cuts off the workpiece clamped on the sub-spindle through the cutting tool 14 on the second tool post 6. Then, driven by the XY-axis moving mechanism, the sub-spindle moves to the right and processes the workpiece through the processing tool 15 on the second tool post. After processing, the sub-spindle releases the workpiece, and the workpiece falls into the storage box. By repeating this process, double-sided processing of the same workpiece can be achieved.
