Description

A Narrow Spacing CNC Inverted Lathe with Convenient Loading and Unloading

technical field

The invention relates to a numerically controlled lathe, in particular to an inverted numerically controlled lathe.

Background technique

With the revitalization and development of the national equipment manufacturing industry, CNC machine tools, as the mainstream product of the machine tool industry, have become the key equipment to realize the modernization of the equipment manufacturing industry. Conventional CNC lathes occupy a large area, and workers have to walk more distances when operating multiple machines, which increases the labor intensity of workers and affects work efficiency; in addition, with the tightening of land resources, the cost of processing sites is getting higher and higher, so It is hoped that the equipment can be more compact and miniaturized, so as to increase the volume ratio of the workshop and reduce management costs. At present, the inverted car on the market is a cross slide with the spindle unit installed in the X direction and the Z direction. Although the chuck can be used to pick and place materials, the machine occupies a large space, which is not conducive to the parallel layout of multiple spindles. ;In addition, because the main shaft of the inverted car is facing downward, manual loading is relatively more difficult than vertical or horizontal cars, and the loading and unloading efficiency is lower. Therefore, it is best to use machinery for automatic loading and unloading.

Contents of the invention

The object of the present invention is to provide a numerical control inverted lathe with compact operating space, easy assembly and convenient loading and unloading.

In order to achieve the above-mentioned purpose of the invention, the technical solution adopted in the present invention is as follows: it is mainly composed of a spindle unit, an X-direction CNC slide table, a Z-direction CNC slide table, and a CNC turret tool holder. On the slide plate of the CNC slide table, the X-direction CNC slide table is installed horizontally on the machine base, and the guide rail of the X-direction CNC slide table is perpendicular to the direction of the worker's operation surface; the Z-direction CNC slide table is vertically fixed or connected. On the slide body of the X-direction CNC slide table; the CNC turret tool holder is installed on the slide plate of the X-direction CNC slide table, the rotation axis of the CNC turret tool holder is parallel to the guide rail of the X-direction CNC slide table, and the CNC turret The cutter head of the tool post faces the worker's operating surface; the CNC turret tool post is located directly under and behind the main shaft unit; a pick-up and delivery table is installed directly under and in front of the main shaft unit, which can automatically move to and from the bottom of the main shaft unit. The unit can move up and down, and the chuck on the spindle unit can loosen the workpiece freely, so the loading and unloading mechanism of this machine only needs to have the function of picking up and feeding materials. It preferably uses a power slide table and a rotary table structure, which can move when loading and unloading After picking up and delivering the material under the main shaft, exit without affecting the work of the main shaft unit and the CNC turret tool rest; the present invention prefers a rotary upper and lower mechanism, which protrudes short relative to the operating surface, and is convenient for changing the blades on the CNC turret tool rest .

As a further improvement of the above-mentioned technical solution, the material receiving and feeding workbench is a rotary table, and a positioning plate for loading and unloading workpieces is installed on the rotary table, and a piece of the rotary plate on the rotary table is cut off to facilitate the spindle unit and the CNC turret tool holder. Carry out cutting processing; the rotary power of the rotary table can be realized by CNC motor acceleration and decelerator, ordinary motor plus cam mechanism, pneumatic, hydraulic, and its rotary positioning mainly meets the accurate positioning accuracy when the loading workpiece position rotates below the spindle That is, the other following material levels, when turning to the front, the artificial upper and lower material levels have almost no effect on the rotation accuracy of the upper and lower materials; the present invention preferably drives the rotary table by means of a numerical control motor acceleration and decelerator, which is convenient to adjust, flexible to rotate, and high in precision , Transposition fast.

As a further improvement of the above-mentioned technical solution, the feeding and receiving workbench is a power slide table, which can be driven by a screw rod and a motor, or can be driven by a cylinder. In the present invention, two linear guide rails and one rodless A slide structure composed of cylinders.

The beneficial effects of the present invention are: 1. In the present invention, since the X-direction CNC slide table and the CNC turret tool rest are installed in a direction perpendicular to the direction of the worker's operation surface, this structure advantageously shortens the space of the operation surface, thereby benefiting multiple The group lathe is compact and side by side. In addition, the transmission parts such as the servo motor and the screw seat of the X-direction CNC slide table of this structure are installed at the rear of the machine, which is beneficial to the later maintenance; 2. The spindle unit of the inverted lathe of the present invention is only installed on the Z-direction movement, its rigidity is much stronger than that of the inverted car spindle unit on the market, which can move in XZ direction; 3. Since the CNC turret tool post is installed horizontally, the iron filings falling on the tool post after processing are easy to get stuck on the tool post 4. A loading and unloading mechanism is installed directly under and in front of the spindle unit of the present invention, so that it is very convenient for workers to load and unload materials, and it can save the waiting time for workers to load materials in advance, and workers do not need to clamp and loosen the clamps when loading and unloading materials. 5. The loading and unloading mechanism adopts a rotary table structure, which is simple and economical in structure, and easy to install, without affecting the replacement of blades. In addition, it is easy to adjust, flexible in rotation, high in positioning accuracy, and fast in indexing.
