Shaft workpiece boring and milling clamping auxiliary adjusting device

Abstract

The invention relates to a shaft workpiece boring and milling clamping auxiliary adjusting device, and belongs to the technical field of machining auxiliary equipment. According to the technical scheme, the cross sections of a movable ramp iron (2) and a fixed ramp iron (4) are of right triangle shapes, the cross section of an adjusting ramp iron (6) is of isosceles trapezoid shape matched with the movable ramp iron (2) and the fixed ramp iron (4), and the adjusting ramp iron (6) is arranged between the movable ramp iron (2) and the fixed ramp iron (4); and the movable ramp iron (2), the adjusting ramp iron (6) and the fixed ramp iron (4) are stacked up and dowm together to form a cuboid, the periphery of the cuboid is provided with a baffle, a V-shaped cushion iron (1) is fixed on the movable ramp iron (2), an adjusting bolt (3) is in threaded connection with the adjusting ramp iron (6), and the baffle (5) is provided with sliding grooves matched with the adjusting bolt (3) and the movable ramp iron (2). The shaft workpiece boring and milling clamping auxiliary adjusting device has the beneficial effects that the stability of workpiece clamping can be ensured, the adjustment is convenient, the adjustment precision is high, and the boring and milling machining requirements can be met.

Description

technical field [0001] The invention relates to an auxiliary adjustment device for boring and milling chucking of shaft workpieces, belonging to the technical field of machining auxiliary equipment. Background technique [0002] In the machining workshop, some large stepped shaft workpieces need to punch center holes at both ends of the workpiece before turning and clamping, and some shaft workpieces need to bore and mill blind and deep holes on the body according to the drawing requirements. The above two workpieces are in When machining and clamping on the boring machine table, first of all, ensure that the workpiece is placed stably and firmly on the boring machine table; secondly, it is necessary to ensure that the axis of the workpiece after clamping is parallel to the boring machine table, so that the workpiece can be turned. The machining allowance, the inner hole and the outer circle meet the coaxiality requirements when milling and boring the hole. [0003] In orde...

Problems solved by technology

The adjustment value of the center height of the workpiece needs to calculate the thickness of the required backing plate according to the angle of the ordinary V-shaped shim iron, and the thickness of the backing plate is usually several common specifications, and the approximate thickness can be obtained through various combinations. This method Time-consuming and labor-intensive, and the accuracy is not high; and because the weight of the workpiece is large, the crane needs to cooperate when adjusting the backing plate, the lifting is laborious, and safety accidents are prone to occur. Considering safety and operation, the number of lifting should be reduced
