Explain the layout of the CNC lathe tool holder
The horizontal bed of the CNC lathe has good manufacturability and is convenient for the processing of the guide surface. The
horizontal bed is equipped with a horizontally configured knife to
increase the speed of the tool holder. It is generally used for the
layout of large CNC lathes or small precision CNC lathes. However, the space below the horizontal bed is small, which makes it difficult to remove chips. From
the structural size, the horizontal placement of the tool holder makes
the horizontal length of the slide plate longer, thereby increasing the
structural size in the width direction of the machine tool. The horizontal bed is fitted with a sloping slide and the layout of the inclined rail guard is configured:
1. It has the characteristics of good horizontal bed craftsmanship.
2. The size of the machine tool in the width direction is smaller than that of the horizontal configuration skateboard, and the chip removal is convenient.
The layout of the horizontal bed with the inclined slide and the inclined bed configuration of the inclined slide is commonly used by small and medium-sized CNC lathes. This is because the two layouts are easy to remove chips, the chips do not accumulate on the guide rails, and the automatic chip conveyor is easy to install; the operation is convenient, the robot is easy to install, and the single machine is automated; the machine has a small footprint and a simple appearance. Easy to achieve closed protection. The following explains the layout of the CNC lathe tool holder:
The tool holder of CNC lathe is an important part of the machine tool. The tool holder is used to clamp the cutting tool. Therefore, its structure directly affects the cutting performance and cutting efficiency of the machine tool. To a certain extent, the structure and performance of the tool holder reflect the numerical control. The design and manufacturing level of lathes. With the continuous development of CNC lathes, the structure of the tool holders continues to innovate, but in general it can be roughly divided into two categories, namely, knife-type tool holders and turret-type tool holders. Some turning centers also use automatic tool changers with a tool magazine.
The knife-type tool holder is generally used for small CNC lathes. Various tools are arranged and clamped on the movable slide plate, and automatic positioning can be realized when the tool is changed. The turret type tool holder is also called a turret or a knife table. It has two forms of vertical and horizontal structure. The multi-tool automatic positioning device realizes the automatic tool change action of the machine tool through the rotation, indexing and positioning of the turret head. The turret type tool holder should be accurate in indexing, reliable in positioning, high in repeat positioning accuracy, fast in indexing speed and good in clamping, to ensure high precision and high efficiency of the CNC lathe. Some turret-type tool holders can not only achieve automatic positioning, but also transmit power.
At present, the two-coordinate linkage lathe mostly adopts a 12-station turret type tool holder, and also adopts a 6-station, 8-station, 10-station turret type tool holder. There are two forms of turret type tool holders on the machine: one is a turret type tool holder for processing disc parts, the rotary axis is perpendicular to the main axis; the other is used for machining shafts and discs. The turret of the part has a rotary axis parallel to the main axis. The four-coordinate controlled CNC lathe has two independent slides and a turret-type tool holder, so it is called a double-turret four-axis CNC lathe.
Among them, the cutting feed amount of each tool holder is separately controlled. Therefore, the two tool holders can simultaneously cut different parts of the same workpiece, which not only expands the processing range, but also improves the processing efficiency. The four-axis numerical control lathe has a complicated structure and needs to be equipped with a special numerical control system to realize the control of two independent tool holders, and is suitable for processing parts with complicated shapes and large batches such as crankshafts and aircraft parts.
