Device for positioning and protecting guide rail of protective door of numeric control processing center

Abstract

The invention relates to a device for positioning and protecting a guide rail of a protective door of a numeric control processing center. The device comprises a processing center machine body, the protective door, a left protective device and a right protective device, wherein the left protective device comprises a left protective mechanism and a left fixed base; the right protective device comprises a right protective mechanism and a right fixed base; the left protective mechanism and the right protective mechanism are fixed on the machine body respectively; the left protective mechanism comprises a guide bearing, a left guide shaft fixing piece and a bearing fixing piece; the bearing fixing piece is fixed on the processing center machine body through a bolt; and a guide bearing is fixed on the bearing fixing piece. The device can cut off the power when the protective door is opened, and dual protection is designed, so the operation is more secure; moreover, the device can conveniently convey and clamp the workpieces, in particular large-size workpieces.

Description

technical field [0001] The invention designs a numerical control machining center, and in particular relates to a protective door guide rail positioning protection device of the numerical control machining center. Background technique [0002] In the design of the protective door of the existing CNC machining center, the prior art uses a long guide rail spanning two protective doors and the entire workbench for guidance and positioning. The guide rail is fixed on the outer protection through the guide rail fixing piece. This structure faces the problem of guiding the protective door of the machining center, the limit of the protective door of the machining center, and the problem of power failure when the machining center is opened. 2) The guide rail spans the entire workbench, which is not conducive to the clamping and lifting of the workpiece; 3) The length of the guide rail is long, requiring high straightness of processing, which increases the difficulty of processing. ...

AI Technical Summary

Problems solved by technology

This structure faces the problem of guiding the protective door of the machining center, the limit of the protective door of the machining center, and the problem of power failure when the machining center is opened. 2) The guide rail spans the entire workbench, which is not conducive to the clamping and lifting of the workpiece; 3) The length of the guide rail is long, requiring high straightness of processing, which increases the difficulty of processing

It is not conducive to installation and debugging, long processing time and low production efficiency

Because the bearing is fixed on the two protective doors through the bearing fixing parts, and switches together with the protective doors, it is inconvenient for the protective doors. Since a beam spans the two protective doors, it affects the processing of the workpiece and seriously hinders the CNC machining center. In addition, the operator may make mistakes and open the protective door during the working process of the machining center, which may cause loss of life and property, and safety cannot be guaranteed
