The electronic display of the value is connected.

Further, the detection device includes a pair of transverse slide rails arranged on the other side of the fixed plate, a slide seat slidingly fitted on the slide rails, a detector is provided on the slide seat, and the detection apparatus The end of the instrument close to the fixed plate is provided with a diameter measuring probe for clamping on the outer diameter of the workpiece.

Further, the detector is also provided with a handle for pushing the detector to slide left and right.

Further, the front side of the base is also provided with a detection mechanism that can be slid and adjusted laterally and is used to detect the coaxiality of the workpiece.

Further, the detection mechanism includes a horizontal slide rail arranged on the front side of the base, a slide block slidingly fitted on the horizontal slide rail, a support rod is provided on the slide block, and the support rod A cantilever that can be adjusted up and down and turned to the rear side is provided on the top, and a dial indicator for detecting the coaxiality of the workpiece against the outer diameter of the workpiece is provided on the cantilever.

Further, the slider is provided with hand-tightening bolts that pass through the slider longitudinally for locking and positioning the slider on the horizontal slide rail.

Compared with the prior art, the present invention has the following advantages: the inspection tool is not only compact in structure, but also can be adjusted horizontally, which is convenient for detecting the outer diameter of workpieces of different specifications and sizes; at the same time, the detection accuracy is high, no manual reading is required, and the detected data Visual display.

detailed description

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific examples are given together with the accompanying drawings and described in detail as follows, but the present invention is not limited thereto.

Refer to Figure 1 and Figure 2

An adjustable reading-type special inspection tool for outer diameter, including a base 10, the rear side of the base is provided with an oblique fixed plate 20 connected to the base through a support frame 11, and one side of the fixed plate is provided There is a fixed plate 30 for installing the workpiece and a positioning boss 31 in the middle, and the other side of the fixed plate is provided with a detection device 40 that can slide laterally for detecting the outer diameter of the workpiece, and the output end of the detection device is arranged on the base Another side part is connected with the electronic display instrument 60 that is used for outer diameter numerical value, so that the outer diameter numerical value of detection is displayed on the electronic display instrument, and this electronic display instrument is provided with electronic display screen and scale scale.

In this embodiment, the detection device includes a pair of transverse slide rails 41 arranged on the other side of the fixed plate, on which a slide seat 42 slidingly matched with it is provided, and a detector is provided on the slide seat 43. The end of the detector close to the fixed plate is provided with a detection end 44 for clamping on the outer diameter of the workpiece, and a diameter measuring probe 45 is arranged on the detection end.

In this embodiment, the detector is also provided with a handle 46 for pushing the detector to slide left and right, so as to manually push the detector close to the workpiece.

In this embodiment, the front side of the base is also provided with a detection mechanism that can be slid and adjusted laterally and is used to detect the coaxiality of the workpiece.

In this embodiment, the detection mechanism includes a horizontal slide rail 51 arranged on the front side of the base, a slide block 52 slidingly matched with it is provided on the horizontal slide rail, and a support rod 53 is provided on the slide block , the support rod is provided with a cantilever 54 that can be adjusted up and down and turned to the rear side, and the cantilever is provided with a dial gauge 55 for checking the coaxiality of the workpiece against the outer diameter of the workpiece, so that the The sub-meter detects the coaxiality of the workpiece.
