Numerical control machining center with elastic clamping jig

Abstract

The invention relates to a numerical control machining center with an elastic clamping jig. The numerical control machining center comprises a numerical control machining machine shell, a touch display screen, a control system, the elastic clamping jig and a machining tool bit system. The elastic clamping jig comprises an elastic clamping mechanism, the elastic clamping mechanism comprises a clamping base, a fixed clamping piece, a movable clamping assembly and a clamping loosening and tightening lead screw, the fixed clamping piece is fixedly arranged on the clamping base, and the movable clamping assembly is arranged on the clamping base in a sliding mode; the movable clamping assembly is in driving connection with the clamping loosening and tightening lead screw; and the movable clamping assembly comprises a first movable block, a second movable block and an adjusting spring, and the first movable block and the second movable block are connected through the adjusting spring. According to the numerical control machining center with the elastic clamping jig, a workpiece is elastically clamped, and the situation that the workpiece is stably clamped through elastic clamping, and meanwhile the workpiece cannot be clamped too tightly; and the machining reject ratio of the workpieces is reduced, and the machining efficiency of the workpieces is improved.

Description

Technical field [0001] The present invention relates to the technical field of CNC machining equipment, and more particularly to a CNC machining center having an elastic assembly. Background technique [0002] CNC machining center for processing of workpieces. The CNC machining center has an input system, a control system, an operating system, and the like, and the corresponding control signal is issued to the operating system after the operation of the input system input, and the control system performs corresponding control signals according to the control signal. [0003] When machining the workpiece, the CNC machining center needs to make the workpiece by loading. When the existing CNC machining equipment, when the generner is fitted with the workpiece, if the workpiece is easy to shift during the processing, the workpiece is unqualified, and the bad rate is high; Or during processing, the workpiece falls from the mounting fixture to effect the processing efficiency of the CN...

AI Technical Summary

Problems solved by technology

In the existing numerical control processing equipment, when the clamping fixture clamps the workpiece, if the workpiece is clamped too loosely, the workpiece will easily shift during the processing process, resulting in the processed workpiece being unqualified, and the defect rate remains high; Or during the processing, the workpiece falls from the clamping fixture, which affects the processing efficiency of the CNC processing equipment;

[0004] If the clamping fixture clamps the workpiece too tightly, it will easily cause the workpiece to be overstressed and damaged; and excessive clamping force will easily cause the clamping fixture to loosen and shorten the service life of the clamping fixture; That is, if the clamping fixture clamps the workpiece too tightly, frequent repairs and replacement of the clamping fixture are required, resulting in low processing efficiency and high maintenance costs
