Straightness detection device for inner hole of spindle storing drum

Abstract

The invention relates to a straightness detection device for an inner hole of a spindle storing drum. The straightness detection device comprises two adjusting bases, a leveling ruler guide rail, a linear slide block and a dial gage, wherein the two ends of the leveling ruler guide rail are arranged on the two adjusting bases, respectively; the linear slide block with the length identical to that of the leveling ruler guide rail is arranged at the upper end of the leveling ruler guide rail; the dial gage is arranged on the linear slide block; slide chutes matched with the linear slide block are formed in the upper and lower ends of the dial gage; a vertical adjusting mechanism and a horizontal adjusting mechanism are also arranged on the adjusting bases. According to the straightness detection device provided by the invention, the leveling ruler guide rail is adjusted to a required angle through the adjusting bases, is located in a horizontal straight line and passes through a to-be-measured deep hole; the straightness of the deep hole can be accurately measured through the dial gage; the straightness detection device can be excellently applied to measurement for the straightness of deep holes.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a straightness detection device for the inner hole of an ingot holding cylinder. Background technique [0002] Deep hole processing is complex and special. The processing process is affected by many factors such as processing technology constraints, machine tool function restrictions, workpiece materials, etc., which will inevitably cause deviations in the straightness of the inner hole of the processed workpiece. The straightness of the inner hole of the workpiece for general use It does not need to be very accurate, because the plunger matched with the inner hole is sealed by a soft sealing ring, and the diameter of the inner hole does not need to be consistent with the tolerance, but for the processing of the ingot cylinder, it is used for extrusion heating at 500 For the left and right alloy materials, the cooperation between the metal plunger and the inner hole ...
