Numerical control machine tool with built-in automatic loading and unloading mechanism and method for loading and unloading workpiece

Abstract

The invention relates to a numerical control machine tool internally provided with an automatic feeding and discharging mechanism and a method for conducting workpiece feeding and discharging, and belongs to the field of machining automation. According to the technical scheme, the numerical control machine tool comprises a machine tool body with a base. A working table and a stand column which can move in the Y direction and the X direction respectively or at the same time are arranged on the base of the machine tool body, and a main shaft box is arranged on the stand column and can move in the Z direction. The numerical control machine tool further comprises a feeding and discharging pneumatic claw arranged on one side of the main shaft box, the feeding and discharging pneumatic claw comprises an L-shaped platy installation support fixed to the main shaft box, the long plate part of the installation support is fixed to the main shaft box, the short plate part of the installation support is provided with a feeding and discharging clamping claw and a drive cylinder, a rotary working table and a material discharge plate which are vertically arranged are arranged on the working table, a penetrating hole is formed in the middle of the rotary working table, and an auxiliary clamp and a blank supporting mechanism which are located at the same height as the penetrating hole are arranged on the two sides of the rotary working table respectively.

Description

technical field [0001] The invention relates to a numerically controlled machine tool with a built-in automatic loading and unloading mechanism and a method for loading and unloading workpieces, belonging to the field of machining automation. Background technique [0002] The loading and unloading mechanisms of general machine tools are manual loading and unloading and loading and unloading air claws, and the machine tool itself does not have the loading and unloading function. With the development of industrial automation, the application of the upper and unloading air claws will become more and more extensive. The upper and unloading air claws are a kind of high-tech automatic production equipment developed in recent decades. The ability to work is an important branch of the unloading air claw robot in the industry. The feed speed of the CNC machine tool has been increased from the original 10 meters and 12 meters to the current 120 meters, which greatly improves the proce...

AI Technical Summary

Problems solved by technology

The purchase and use costs of the upper and unloading air claws are relatively high, and the processing and assembly precision and complexity of the components on the upper and unloading air claws are also very high

Therefore, the loading and unloading air claws are rejected by small and medium-sized production enterprises, and the labor-intensive manual loading and unloading is still used.
