[0002] In the precision machining industry, Fanuc machine tools are widely used. Such machine tools are equipped with a spindle, a tool turret, and a working platform. During the process of machining products, every time a product is machined, a yellow light on the machine tool lights up to prompt the operator to replace the product. After the operator replaces it, the start button is pressed to start machining the next product.

[0003] The above-mentioned use method of the Fanuc machine tool requires manual monitoring and also requires manual replacement of the machined and to-be-machined products, which will lead to problems such as long material change time and high labor cost. In order to save the manual material change time and improve the machining efficiency, at this time, we provide an intelligent auxiliary machining device for a CNC machine tool to solve the above problems.

A clamping assembly is arranged above the four-axis base of the machine tool. The clamping assembly includes a machine tool spindle and a grasping mechanism arranged on the machine tool spindle. A spindle air circuit for controlling the movement of the machine tool spindle is arranged on the machine tool spindle, and a grasping air circuit for controlling the grasping of the grasping mechanism is arranged on the grasping mechanism. The spindle air circuit is connected to an external control system, and the grasping air circuit is also connected to the external control system.

[0006] Preferably, the grasping mechanism includes a tool shank and a pick-up presser installed inside the tool shank.

[0007] Preferably, the product placement device is a placement box placed on one side of the product placement fixture.

[0008] Preferably, a positioning assembly for fixing the machining fixture and the product placement fixture is arranged on the four-axis base of the machine tool. The positioning assembly includes a groove opened on the four-axis base of the machine tool. The positioning assembly further includes a limiting block arranged on the machining fixture and the product placement fixture. The limiting block is adapted to the groove. The machining fixture and the product placement fixture are also fixed to the four-axis base of the machine tool by bolts. The number of the grooves is the same as that of the limiting blocks.

[0009] Compared with the related technologies, an intelligent auxiliary processing device for a CNC machine tool provided by the present utility model has the following beneficial effects: The device controls the spindle air circuit and the grasping air circuit through a control system. Then, when processing a product, the machine tool spindle moves to the product placement fixture, and the material taking and pressing gripper installed on the tool holder, under the action of the spindle air circuit and the grasping air circuit, grasps the product and places it on the processing fixture, and then starts processing. When the product is processed, then switch back to the original air circuit, so that the original air circuit can control the machine tool spindle and the grasping mechanism, grasp the processed product and place it into the product placement device, and grasp the product to be processed on the product placement fixture and place it on the processing fixture. At this time, start processing the next product, repeat the above actions until all the products on the product placement fixture are processed, the machine tool lights up a yellow light, remove the processed product, and at the same time place the product to be processed, press the start button, and perform the next round of processing.
