Limiting and clamping device for machining center

Abstract

The invention relates to a limiting and clamping device for a machining center. The device comprises a rack outside a machining center conveyor, the rack is provided with at least one limiting frame and a clamping mechanism, a walking driving mechanism used for driving the limiting frame to reciprocate in the parallel direction of the conveyor is arranged at one side of the limiting frame, a driving plate is arranged at the top of a limiting plate of the limiting frame, a deflection shaft and a deflection mechanism are arranged between the driving plate and the other side of the limiting frame, the deflection mechanism is used for driving the driving plate to deflect around the deflection shaft in a reciprocating manner, and the clamping mechanism comprises two first clamping plates movingoppositely in the vertical conveying direction of the conveyor and a second clamping plate moving relative to a fixing table in a lifting manner. The walking limiting frame drives the driving plate to deflect in a reciprocating manner through the deflection mechanism, side opening and closing of the limiting plate at the top of the conveyor can be achieved, top feeding is facilitated, repeated positioning is avoided, workpiece clamping is achieved through multi-face limiting clamping in the side direction and the vertical direction of the clamping mechanism, the positioning precision, the clamping efficiency and the reliability can be improved, and the compact continuous production requirement of the machining center is met.

Description

technical field [0001] The invention relates to a position-limiting clamping device for a machining center, which belongs to the technical field of numerical control machining center equipment. Background technique [0002] The high-efficiency automatic CNC machining center, which is composed of mechanical equipment and CNC system, is suitable for processing complex parts. It has the characteristics of high processing precision and batch processing efficiency. It is widely used in milling, boring, drilling, sawing and other processing procedures. Among them, the limit clamping device is involved on the conveyor of the machine tool, which is used for limit clamping and positioning of one or more workpieces, so as to control the processing position and prevent the displacement and vibration of the workpiece during the machining process of the machining center, which will affect the machining accuracy. The limit clamping of CNC machining center equipment in the prior art genera...

AI Technical Summary

Problems solved by technology

The limit clamping of CNC machining center equipment in the prior art generally adopts clamping tooling, especially when the workpiece structure needs to be fixed at multiple points, resulting in poor clamping efficiency and positioning accuracy. The surface of the bar workpiece is reliably clamped. At the same time, when the vertical lifting limit structure is adopted on the conveyor of the machining center, the impact of the lifting impact on the conveyor will easily reduce the life of the conveyor. When the overall length of multiple workpieces is long, especially continuous When processing and loading from the top, it is necessary to repeatedly shift the limit structure to make way for the loading, and the repeated limit positioning will affect the feeding efficiency and the positioning accuracy of batch processing, and it is difficult to meet the compact continuous production requirements of the machining center
