Abstract
The utility model discloses an adjustable check bar, and comprises a base, a check bar body, screw rods and nuts. The screw rods are arranged on the base; the screw rods are locked by the nuts; the check bar body is arranged between the screw rods and are locked and fixed by the nuts. The base is of cylindric shape. The utility models is applicable for adjustment and check of precision of main shafts of large aperture machine tools and rotary central frames, and can be used when ordinary check bars fail. In addition, the utility model has simple structure, and can be processed and used conveniently.
Description
Technical field
The utility model relates to the adjustment and the instruments of inspection of the main shaft precision that is applicable to large aperture lathe and Rotation Center Rest, is a kind of adjustable inspection rod specifically.
Background technology
The common inspection rod of tradition is that base has tapering, will insert spindle taper hole with the one side of awl during use and get final product, but the main shaft of large aperture lathe and Rotation Center Rest is very thick that it is very difficult to make the common inspection rod supporting with it, and cost is also very high, and versatility is not strong,
The utility model content
The purpose of this utility model provides a kind of adjustment and check that is applicable to the main shaft precision of large aperture lathe and Rotation Center Rest, a kind of adjustable inspection rod that uses under the excellent out of use situation of common inspection.
The purpose of this utility model is achieved in that a kind of adjustable inspection rod, is made up of base, inspection barred body, screw rod and nut, on the described base screw rod is housed, and screw rod is adorned an inspection barred body by nut lock between the screw rod, fixed by nut lock.
Described base is a cylindrical shape.
Described inspection barred body is evenly distributed with 4 open-works on φ 165 circles.
The utility model is applicable to the adjustment and the check of the main shaft precision of large aperture lathe and Rotation Center Rest, can use under the excellent out of use situation of common inspection, and base is cylindrical shape, and is simple in structure, processes, uses all very convenient.

Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated:
A kind of adjustable inspection rod is made up of base, inspection barred body, screw rod and nut, and four screw rods 4 are housed on the base 1, screw rod 4 is by nut 2 lockings, adorn an inspection barred body 3 between the screw rod 4, be locked by nut 2, inspection barred body 3 is evenly distributed with 4 φ, 24 open-works 5 on φ 165 circles.
The assembling of inspection rod: at first 4 screw rods 4 are screwed on the cylindrical base 1, and screw rod 4 are locked on the base 1, will examine barred body 3 after screw rod 4 lockings and be enclosed within on the screw rod with nut 2, fastening nut, the inspection rod is promptly assembled and is finished.
Set-up procedure: at first adjustable inspection rod 3 is stuck on the chuck, dial gauge is inhaled on lathe bed or knife rest, the gauge outfit of dial gauge is beaten on the excellent base of inspection 1 surface, adjusts the position that is installed of base 1, until coaxial with main shaft.Respectively the percentage gauge outfit is beaten again at the inspection barred body near the root of base with away from base one side's head,, make the inspection barred body coaxial with main-shaft axis by adjusting the nut on the different directions.
Method of operating: by adjusted inspection rod, be the equal of that the axis with main shaft prolongs out, the checkout procedure of this moment is adjustable inspection rod and the checkout procedure of common inspection rod are identical.
