Description

Technical Field

[0001] This utility model relates to the field of CNC machining, specifically to a worktable height adaptive adjustment structure for a flexible production line. Background Technology

[0002] A flexible production line connects multiple adjustable machine tools with automated conveying devices. It relies on computer management and combines various production modes to reduce production costs and maximize resource utilization. CNC machining centers are the most widely used equipment in the mold manufacturing industry. Although the degree of automation is quite high, it is difficult to improve work efficiency without scientific and reasonable fixture support. According to incomplete statistics, one-quarter of the machining time is wasted on clamping preparation and auxiliary time, resulting in extremely low effective working time. At present, China does not lack high-end CNC machining centers or professional technicians, but rather lacks fixtures suitable for the characteristics of this industry, which leads to low production efficiency.
