Device for detecting perpendicularity of spindle box spindle and upright post of boring mill

Abstract

The invention discloses a device for detecting the perpendicularity of a spindle box spindle and an upright post of a boring mill. The device comprises a cantilever, a dial indicator and a datum plate, wherein the side wall plane of one end of the cantilever is completely fit or parallel to the end face of a spindle hole, the other end of the cantilever is a free end, and the dial indicator is fixedly connected to the free end of the cantilever; the datum plate is of a T-shaped structure formed by a wing plate and a bottom plate perpendicular to each other, and the length of at least one wing of the datum plate is smaller than the raised height of a dovetail guide rail; when the device is used, the bottom plate of the datum plate is attached to the upper surface of the dovetail guide rail, the crossing line of the planes of the bottom plate and the wing plate is superposed with the ridge of the dovetail guide rail, and a probe of the dial indicator is next to the reference plane of the wing plate of the datum plate. The device overcomes the defects in the prior art, reduces the labor intensity of workers, shortens the machine overhauling time, and improves the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a verticality detection device, in particular to a device for detecting the verticality of a main shaft and a column of a headstock of a boring machine. Background technique [0002] In the field of mechanical processing, the price of processing machine tools is very high. After long-term use, many moving parts of the processing machine tools will wear out, resulting in lower and lower processing accuracy. In order to improve the processing accuracy of processing machine tools and reduce the cost of new machine tools, generally The processing machine is overhauled. [0003] During the overhaul of the boring machine, one of the most important items is to disassemble the boring machine headstock for maintenance. After the overhaul, it is also necessary to check the verticality of the spindle box of the boring machine and the column of the boring machine to ensure the parallelism o...

Problems solved by technology

If it is not vertical, it can only be disassembled and assembled again, and the workload of workers is very heavy

[0004] The plane of the dovetail guide rail of the boring machine column is parallel to the axis of the main shaft. Except for the dovetail guide rail, the other planes of the boring machine column itself are casting surfaces, and the surface flatness is poor, so it cannot be used as a reference plane for testing.
