Full-automatic feeder of gang tool numerical control lathe

Abstract

The invention relates to a full-automatic feeder of a gang tool numerical control lathe. The front end of a main shaft is sleeved on the outer wall of a clamp device; a supporting sleeve is sleeved on the inner walls of the clamp device and the main shaft; a pushing bar of a pushing cylinder is sleeved on the inner wall at the other end of the supporting sleeve which is provided with a feeding hole communicated with a stock chute; and a feeding cylinder drives and connects with the stock chute. The full-automatic feeder of the gang tool numerical control lathe has simple structure, the main shaft and the supporting sleeve are sleeved behind the clamp device to form a working piece passage; and a bar stock is driven by the feeding cylinder to accurately enter the supporting sleeve and thenis pushed by the pushing cylinder to move and be clamped by the clamp device for processing. The full-automatic feeder of the gang tool numerical control lathe adopts a main-shaft rear-end feeding mode to ensure the enough operation space of a front-end cutter holder of the main shaft, selects the cylinder with lower cost to feed, occupies small space and adopts the feeding cylinder with an inclined angle of 11 degrees to fully prevent working pieces from being overlapped and avoid abnormality in automatic operation process so as to realize automatic feeding.

Description

1. Technical field: [0001] The invention relates to a feeding machine, in particular to an automatic feeding machine used in conjunction with a row-knife numerical control lathe. 2. Background technology: [0002] The application of CNC lathe has become more and more popular with the development of science and technology. It has gradually occupied the field of mechanical processing industry with the advantages of high precision, high efficiency, high cost performance and complex shape of processed products. With the popularization and deepening of the use of CNC lathes, the automatic feeding mechanism that goes with it is also very important. [0003] Since lathe manufacturers usually only provide machine tools, the loading part can only be done manually. [0004] The current automatic feeding machines configured for CNC lathes are mainly for processing long bars (usually between 800-3500mm). For processed bar products with a length L<150, the demand for the products is...

AI Technical Summary

Problems solved by technology

The long bar automatic feeding machine cannot meet the needs of such products. It can only manually feed the products to be processed into the chuck one by one for continuous production operations. The basic operation sequence is: install the workpiece-clamp the workpiece- Close the protective door - start the program - open the protective door - unload the workpiece

[0005] It can be seen from the above operation sequence: 1) The process is cumbersome, one person, one machine, people stop and stop, and the processing efficiency is low

[0006] 2) Employees have high labor intensity, are prone to fatigue, and have potential safety hazards

3) Since the workpiece is manually clamped, positioning errors are prone to occur, see figure 1 , causing defects in product accuracy, affecting product quality, and low pass rate

However, due to the high cost of such products, usually more than 100,000 or even higher, this puts pressure on the cost of the enterprise, and the scope of use is limited
