Compared with the prior art, the roundness detecting device fixes the workpiece to be inspected by using a positioning device mounted on a rotating shaft, and detects the roundness of the workpiece to be detected through a micrometer corresponding to the rotating shaft, and the structure thereof Simple and low cost. [Embodiment] Please refer to ® 1, the roundness detecting device 10 provided by the preferred embodiment of the present invention (the roundness detecting splitting 1) includes a base 11 〇, a rotating shaft 3 201038916 120, a test The micrometer 130, and a positioning device 140. The rotating shaft l2〇_ is rotatably disposed on the base 110. The micrometer 130 corresponds to a household, and the rotating shaft 120 is disposed on the base. A positioning device 140 is disposed on the rotating shaft 120 to fix the workpiece to be inspected. The base 110 includes a bottom plate 112 and an edge of the bottom plate 112. The side wall 114 extends in a direction perpendicular to the bottom plate 112. In the embodiment, the bottom plate 112 is circular, and the side wall 114 forms a circular receiving space 116 around the bottom plate C) 112. A shaft hole 112a is provided at a center of the bottom plate 112 for receiving the rotating shaft 120 therein. A through hole 114a perpendicular to the sidewall 114 and extending through the sidewall 114 is defined in the sidewall 114. The through hole 114a is used to set the micrometer 130. One end of the rotating shaft 120 is rotatably disposed in the shaft hole 112a of the base 11b to drive the workpiece to be detected to rotate by the positioning device 140. It can be understood that in order to reduce the influence of the friction between the rotating shaft 120 and the sidewall of the shaft hole 11a on the measurement result, a rolling bearing may be disposed between the rotating shaft 120 and the side wall of the shaft hole 112a (not shown) Show). The micrometer 130 is disposed on the side wall 114 of the base 11 , and includes a reading meter 132 , a rod 134 and a probe 136 . The reading meter 132 is used to read the value of the surface change of the workpiece to be inspected, and the meter 132 is provided with a metering device. The rod 134 is coupled to the reading meter 132 and is secured to the side wall 114 of the base no through the through hole 114a. The rod 134 is a hollow rod. The probe 136 is connected to the metering device in the meter 132 and protrudes from the end 4 201038916 of the rod 134. When measuring, the probe 136 directly abuts on the surface of the workpiece to be inspected to detect The change in the surface of the workpiece is detected and transmitted directly. The meter 132 is converted by the meter 132 into a specific number of changes _ value that is presented to the user. The positioning device 140 is disposed at an end of the rotating shaft 120 adjacent to the base 110 for supporting a workpiece to be inspected. Referring to FIG. 1 and FIG. 2, in the embodiment, the positioning device 140 includes a plurality of magazines 142 and a plurality of fixing rods 144 and positioning pins 146 that are telescopically disposed in the fixing rods 144.

The spring 142 is sleeved on the fixing rod 144 and is abutted on the end of the positioning pin 146 and the rotating shaft 120. Referring to FIG. 3, in use, an annular workpiece to be inspected 200 is positioned at the end of the rotating shaft 120 through the positioning device 140 and received in the receiving space 116 of the base 110. The positioning pin 146 of the positioning device 140 is abutted against the inner wall of the annular to-be-detected workpiece 200 by the magazine 142, since the positioning pin 146 of the positioning device 140 can be inside the fixing rod 144 Sliding, so that the positioning pin 146 and the magazine 142 form a self-centering structure, and the workpiece to be inspected 200 can be automatically centered. After the workpiece 200 to be inspected is positioned, the micrometer 130 is adjusted to cause the probe 136 of the micrometer 130 to abut on the outer surface of the workpiece 200 to be inspected. Then, the rotation of the rotating shaft 120 drives the workpiece 200 to be detected to rotate. During the rotation, the surface shape of the workpiece 200 to be detected can be read by the micrometer 5 201038916, (10), thereby facilitating Measuring the roundness of the workpiece to be inspected. * I (four) inspection (four) placement (10) knot _ single, can be used to easily measure the roundness - the workpiece to be tested roundness, in addition, the roundness detection device i 1 〇〇 also can be used to the surface roughness of the workpiece to be tested Make measurements. It will be appreciated that the locating pin 146 of the positioning device 14 can be provided with a friction plate to increase the friction between the locating pin 146 and the workpiece to be inspected. It is understood that, in order to prevent the micrometer (10) from generating a self-induced displacement during measurement, a bolt hole may be provided at the top end of the side wall 114 of the susceptor 110 to vertically penetrate the through hole 114a (Fig. And the bolt is placed in the bolt hole 134 on the rod body 134 of the micrometer 13 to fix the micrometer 130 ^ In summary, the invention complies with the invention patent element, and is proposed according to law patent application.
