Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding, in particular to an automatic feeding machine for a spring grinder. Background Art

[0002] Spring grinder machinery is a professional equipment widely used in the spring processing industry. It is mainly used to grind the end faces of various springs to improve the precision and surface quality of the springs. With the development of science and technology and changes in market demand, the types and performance of spring grinding machines are also constantly innovating and improving. In order to ensure the verticality of the helical compression spring, keep the end faces of the two supporting rings in contact with other parts, reduce deflection and ensure the characteristics of the main machine (or parts and components), both end faces of the helical compression spring are generally ground. This process is usually called spring grinding. Modern spring grinder machinery has achieved a high degree of automation and intelligence. By adopting advanced CNC technology and automation equipment, the spring grinding machine can realize a series of operations such as automatic loading, automatic grinding and automatic discharging, which greatly improves production efficiency. At the same time, by adopting an intelligent control system, the spring grinding machine can achieve precise grinding parameter settings and real-time production monitoring to ensure product quality.

[0003] The existing spring grinder machinery is not easy to detect and remove defective springs during transportation.

[0005] Although the above patent achieves the goal of moving the spring to the spring detection distributor for detection and distribution, which greatly improves the efficiency of spring feeding; however, the device lacks the ability to detect and remove defective springs, ensure quality control during the production process, and improve product qualification rate and production efficiency.
