A CNC fully automatic machining center for precision hardware

Abstract

The invention provides a numerically-controlled full-automatic machining center for precise hardware. The numerically-controlled full-automatic machining center comprises a feeding mechanical arm, a feeding platform in front of the feeding mechanical arm and two hardware fixtures which are symmetrically installed on the left side and the right side of the feeding mechanical arm, wherein a hardwarefeeding box is placed on the feeding platform; each hardware fixture comprises a bottom plate, transverse guide rails are transversely arranged on the bottom plates, compression devices are installedon the transverse guide rails, and positioning clamping devices are arranged at the front ends of the compression devices. Each positioning clamping device comprises a rack on the bottom plate, platform plates are installed on the tops of the racks, and a plurality of hardware clamping grooves are formed in the platform plates. The numerically-controlled full-automatic machining center for the precise hardware is high in automatic degree, it can be achieved that multiple pieces of hardware are fed, transferred, positioned, clamped and compressed at a time, the machining efficiency is high, and the precision is high.

Description

technical field [0001] The invention relates to a machining center, in particular to a numerically controlled full-automatic machining center for precision hardware. Background technique [0002] As a precision hardware, the plug terminal needs multiple steps such as stamping, cutting, drilling, and fine grinding in the actual production process. In the prior art, it has been possible to implement a metal processing center composed of manipulators to replace human hands for workpiece transfer. Specifically, grab the workpiece on the material table to the set hardware processing station according to the fixed program, clamp the workpiece and complete one or more hardware processing procedures. Then the processed workpiece is transferred to the product container. [0003] However, the existing hardware processing centers mainly have the following defects: [0004] 1) The quantity of single processing is small, and the production efficiency of the enterprise is low; [0005...

AI Technical Summary

Problems solved by technology

[0004] 1) The quantity of single processing is small, and the production efficiency of the enterprise is low;

[0005] 2) The clamping accuracy of the manipulator is low, which leads to the misalignment of the workpiece and the processing area of ​​the hardware processing station during the processing process, and the low yield rate of product processing, resulting in an increase in production costs;

[0007] 4) In the clamping process, the plug terminal is generally clamped left and right first, and then clamped front and back, but because the force in the clamping process cannot be completely uniform, and the plug terminal is a metal part, it has certain elasticity, especially in the front and rear During the clamping process, the middle part of the plug terminal may slightly protrude upwards, which may lead to deviations in the processing position
