An automatic feeding device for CNC machine tools

Abstract

The invention discloses an automatic feeding device for a numerical control machine tool. The automatic feeding device for the numerical control machine tool is provided with a storage bin body, a material blocking air cylinder, a material blocking plate, a material receiving-feeding air cylinder, a material receiving mechanism and a material ejection structure on one side of a main shaft end. The material blocking plate is installed on a discharging port below the storage bin body in a hinged mode, and the material blocking plate is provided with a limit protrusion which is movably connected with the material blocking air cylinder installed on the storage bin body, the storage bin body is connected with the material receiving mechanism through the material receiving-feeding air cylinder, the material ejection mechanism is arranged on the material receiving mechanism far away from the main shaft side, and an axial locating block is arranged in a fixture. The automatic feeding device for the numerical control machine tool is simple in structure, and stable and reliable in parts receiving and feeding, and the parts and equipment are prevented from abrading through multiple flexibility designs. The automatic feeding device for the numerical control machine tool is low in manufacture cost, and a striker plate and the material blocking plate are convenient to replace and beneficial to maintaining. The automatic feeding device for the numerical control machine tool is high in work efficiency, and when the air cylinder works, laying off, blanking and material ejecting are achieved one by one, and workpiece materials are sent into a main shaft fixture automatically, and automation degree is high.

Description

technical field [0001] The invention relates to a component for a lathe, in particular to an automatic feeding mechanism for a numerically controlled lathe. Background technique [0002] In the machinery manufacturing industry, CNC lathes, especially small CNC lathes, are widely used in processing small bushing parts. When processing such parts, the blanks of the parts include piece materials and bar materials. How to realize the automatic processing of parts, realize the single-machine automation of CNC lathes, and maximize the processing efficiency of machine tools must be made according to different blank parts. different options. If bar is selected as the raw material of the parts, it is necessary to configure complex and high-cost automatic feeding brackets, which will increase the unit cost of the machine tool, and the cost performance of the machine tool is low, which cannot meet the requirements of the enterprise to reduce costs and increase efficiency. On the othe...

Problems solved by technology

If you choose bar material as the raw material of parts, you need to configure complex and high-cost automatic feeding brackets, which will increase the unit cost of the machine tool, and the cost performance of the machine tool is low, which cannot meet the requirements of the enterprise to reduce costs and increase efficiency.

On the other hand, due to the rough processing and simple design of the existing feeding device, the parts are prone to wear or damage to the feeding device during the feeding process.
