Detailed Description

The following describes a concentric dual-axis control mechanism according to the present invention in further detail with reference to the accompanying drawings.

The rapid inspection tool for inspecting the distance between two parallel surfaces and the surface bounce comprises a bottom plate 6 and is characterized in that a first seat 4 and a tail seat 1 for positioning a workpiece are arranged on the bottom plate, a supporting seat 2 is arranged between the first seat and the tail seat, a linear guide rail 5 is arranged on the side portion of the bottom plate, a gauge seat 8 is arranged on the guide rail, a dial gauge 9 is arranged on the gauge seat, the number of the dial gauges is two, and measuring heads of the dial gauge can be respectively pushed into two reference surfaces of a thrust surface.

The outer terminal surface of first seat sets up the second table seat (not shown in the figure), the second table seat also install on the slide rail, the second table seat on set up another amesdial, the gauge head of this amesdial is used for measuring the preceding terminal surface of work piece 3. The first seat and the supporting seat comprise a base, and two supporting wheels 10 are symmetrically arranged on the base in the left-right direction. The tailstock is provided with a tip positioning workpiece. The tailstock is also installed on the slide rail, and the moving position is locked and locked through tailstock locking. The guide rails are respectively arranged on two sides of the bottom plate, and the gauge stand is respectively arranged on the respective guide rails. The bottom plate is also provided with a limiting seat 7, and the limiting seat is provided with a limiting slide block for limiting the moving position of the gauge stand.

The utility model discloses a measure the inspection process as follows:

1) the workpiece is lightly placed on the supporting roller (the front end of the workpiece is leftwards), the central hole at the rear end is tightly attached to the axial positioning steel ball, and the measuring assembly is pushed forwards to the right position. And (3) lightly forcing the workpiece to be tightly attached to the supporting roller and the axial positioning steel ball by turning the right hand right and downwards, and lightly rotating the workpiece for more than one circle.
