Drilling chamfering machine

Abstract

The invention relates to the technical field of guide rail machining, and discloses a drilling and chamfering machine which is characterized in that a drilling device, a movable supporting plate and a chamfering device synchronously move in the length direction of a base, and the drilling device and the chamfering device synchronously move in the width direction of the base; the two sides of the workbench are fixedly supported through a supporting frame of the base and movably supported through a movable supporting plate. The linear driving mechanism is connected with a jacking part, the chamfering machine is in sliding connection with a lifting guide rail on the fixed seat, a guide lifting block provided with a guide curved surface is arranged on the chamfering machine, the guide curved surface comprises a fast forward inclined surface and a working feed inclined surface, and the linear driving mechanism drives the jacking part to move front and back in the length direction of the base. The jacking piece moves along the guide curved surface and simultaneously drives the guide lifting block to move up and down along the height direction of the base; according to the guide rail drilling device, fast forward and working stroke of chamfering can be accurately controlled, deformation of the workbench during drilling of a guide rail workpiece can be effectively reduced through the movable supporting plate, the product machining quality is effectively improved, and the overall structure is simple.

[0002] In the production process of the linear guide rail, it is necessary to drill the mounting hole for the linear guide rail. After the mounting hole is drilled, the bottom of the mounting hole needs to be chamfered, and the feed speed of each stroke of the chamfering device is usually Adjustment is made by drives such as servo motors and hydraulic cylinders, but in actual use, the feed speed of each stroke of the chamfering device is prone to errors, so that the accuracy of chamfering processing cannot be guaranteed, which affects product quality. In addition, when performing straight lines When drilling the installation hole of the guide rail, the guide rail workpiece needs to be fixed on the workbench, and the drilling equipment then drills the guide rail workpiece. However, due to the limitation of the drilling machine structure, the workbench usually has only one side support to form a cantilever structure. In this way, when drilling the guide rail workpiece, the workbench has no balanced support on both sides, which will cause displacement and deformation of the workbench, which will easily cause errors in the drilling process of the guide rail and affect product quality.
