Description

External diameter gauge for measuring the external diameter of the spigot

technical field

The utility model relates to an outer diameter gauge for measuring the outer diameter of a spigot.

Background technique

When processing the spigot with a diameter of 26mm in the bearing seat, since the spigot is only 2 mm high and the size is large, an outer diameter micrometer with a specification of 250-275 mm is required, which is heavy and difficult to hold flat when measuring, which is inconvenient for workers to operate. It affects the measurement accuracy, and the measurement is slow, which affects the production efficiency. Moreover, the scale line of the outer micrometer is not obvious, and is greatly affected by light, which makes it difficult to read, increases the difficulty of measurement for operators, and increases human error.

Utility model content

The technical problem to be solved by the utility model is to provide an outer diameter gauge for measuring the outer diameter of the spigot with simple structure, convenient measurement and high measurement accuracy.

In order to solve the above problems, the utility model provides an outer diameter gauge for measuring the outer diameter of the spigot, which includes: a measuring bracket, two ends of the measuring bracket are respectively provided with a left bump and a right bump protruding to the same side, along the The through hole arranged on the right bump along the length direction of the measuring bracket, and the threaded hole arranged on the left bump along the length direction of the measuring bracket, the dial indicator arranged on the through hole through the measuring rod, and the dial indicator The cylindrical measuring head connected to the bottom of the measuring rod of the watch, the bottom is set on the positioning measuring head in the threaded hole; the bottom of the positioning measuring head is provided with a thread for matching with the threaded hole.

A relief slot for accommodating a cylindrical measuring head and a positioning measuring head is provided on the measuring bracket and between the left and right protrusions.

One side of the right protrusion is provided with a threaded hole. The screw in the threaded hole is used to fix the data of the dial indicator.

Compared with the prior art, the utility model has positive effects: the utility model has a simple structure for measuring the outer diameter of the spigot outer diameter. Before measuring the workpiece, adjust the dial indicator to a suitable position and lock it with the side screw, place the outer diameter gauge on the standard size of the workpiece to be measured, and adjust the pointer of the dial indicator to zero position; put the calibrated outer diameter Place the gauge on the workpiece, place the measuring base on the upper plane, and position the probe to touch the outer diameter. Depending on the size, the swing position of the pointer is different. The scale indicated by the pointer is the deviation of the workpiece from the standard size.

Description of drawings

In order to make the utility model can be understood more clearly, the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

Fig. 1 is the structural diagram of the outer diameter gauge of measuring the spigot outer diameter of the utility model;
