It should be noted that the preset angle of the present embodiment can be specifically set according to the detection requirement, and only the preset angle needs to be ensured not to exceed the rotation range of the rotation structure 500. Meanwhile, the rotating structure 500 of the present embodiment includes a first rotating arm 510, a second rotating arm 520, and a pin 530, and the second rotating arm 520 is rotatably connected to the first rotating arm 510 through the pin 530. The first arm 510 has at least one first fixing hole 511 (shown in fig. 4), and the second arm 520 has at least one second fixing hole 521. Of course, the rotation structure 500 may further include more rotation arms, such as a third rotation arm, a fourth rotation arm, and the like, when the rotation structure 500 further includes other rotation arms, the other rotation arms are placed on the second bearing surface 133, and the detection under the preset angle of the other rotation arms can be also completed, so that the detection tool 100 for detecting a rotation structure of the embodiment is also suitable for the rotation structure 500 with multiple rotation arms.

In addition, it should be noted that the movement of the second reference block 130 in the height direction of the first support block 120 is understood to include the following ways: 1. the second reference base 130 can move up and down along the height direction of the first support base 120; 2. the second reference holder 130 may also be moved in an obliquely upward and downward manner in a direction intersecting the height direction of the first support holder 120. Meanwhile, the second reference seat 130 may move on the first support seat 120 in a plurality of manners, and only the height position of the second reference seat 130 on the first support seat 120 needs to be changed, for example, a guide rail structure, a screw structure, a buckle structure, etc. are arranged between the second reference seat 130 and the first support seat 120. In order to facilitate understanding of the height direction of the first support base 120 of the present embodiment, taking fig. 1 as an example, the height direction of the first support base 120 is a direction indicated by any arrow S in fig. 1.

Further, referring to fig. 1, the first support base 120 is provided with a first guide portion 121. The second reference base 130 is provided with a second guide portion 131 which is guided and engaged with the first guide portion 121. The guiding directions of the first guiding portion 121 and the second guiding portion 131 are perpendicular to the second bearing surface 133, respectively. Therefore, the second reference seat 130 can change the height position of the second reference seat 130 on the first support 120 by the movement of the second reference seat 130 under the action of the first guide part 121 and the second guide part 131, so that the second rotating arm 520 can be overlapped on the second bearing surface 133. Meanwhile, the first guide part 121 is matched with the second guide part 131, so that the second reference seat 130 moves more stably on the first support seat 120, which is beneficial to improving the detection precision of the rotating structure 500.

The guiding directions of the first guide portion 121 and the second guide portion 131 are understood as follows: the placing direction of the first guide portion 121 on the first support base 120; it can also be understood that after the first guide part 121 is disposed on the first support seat 120, the length direction of the first guide part 121 is the guide direction of the first guide part 121; similarly, the guiding direction of the second guiding portion 131 should be explained.

Alternatively, the first guide part 121 may be a guide rail, and the second guide part 131 may be a guide groove or a slider; or the first guide part 121 may be a guide groove or a slider, and the second guide part 131 may be a guide rail.

Further, referring to fig. 1 and 7, the first guiding portion 121 is a guiding rail. The second guide portion 131 is a slider that is guided and engaged with the guide rail, so that the movement of the second reference block 130 is more stable by the engagement of the slider with the guide rail.

In one embodiment, referring to fig. 1, the checking fixture 100 for detecting a rotation structure further includes a base 150 and an elastic member 160. The second reference seat 130 is mounted on the base 150 by the elastic member 160, and thus, when the second rotating arm 520 is rotated and the second reference seat 130 is driven to move on the first supporting seat 120, the elastic member 160 is compressed and applies an elastic force to the second reference seat 130, so that the second reference seat 130 and the second rotating arm 520 are always in a contact state; meanwhile, the second reference seat 130 is slowly moved under the action of the elastic member 160, so that the use stability of the detecting tool 100 for detecting the rotating structure is improved.

Alternatively, the elastic member 160 is a spring or an elastic rubber member.

Further, referring to fig. 1, the elastic member 160 is a spring. One of the second reference block 130 and the base 150 is provided with a guide member (not shown), and the other of the second reference block 130 and the base 150 is provided with a guide hole 151 in guiding fit with the guide member. The spring is sleeved on the guide member, so that the movement of the second reference block 130 on the base 150 is more stable by the cooperation of the guide member and the guide hole 151. Meanwhile, the spring is sleeved on the guide piece, so that the spring is stably compressed and stretched, and the phenomenon that the spring is bent in the compression process to damage the use stability of the checking fixture 100 for detecting the rotating structure is avoided.

The first positioning hole 123 and the second positioning hole 135 cooperate to reset the theoretical initial position of the second reference seat 130. Thus, when the detection is not needed, the positioning element 190 is inserted into the first positioning hole 123 and the second positioning hole 135, so that the second reference seat 130 maintains an initial state on the first supporting seat 120 for subsequent detection and reuse.

It should be noted that the positioning element 190 only needs to be inserted into the first positioning hole 123 and the second positioning hole 135, for example, the positioning element 190 is a bolt, a screw, a pin, an iron rod, a plug, or the like.

The detecting pin 321 is used for detecting the position of the second fixing hole 521 of the second rotating arm 520 and the profile of the fixing surface corresponding to the second fixing hole 521, so that when the second rotating arm 520 is supported on the second supporting surface 133, the detecting base 320 is moved, and the detecting base 320 is attached to the second rotating arm 520. Since the detection base 320 has a profiling surface facing the fixing surface corresponding to the second fixing hole 521, the detection base 320 can be matched with the fixing surface corresponding to the second fixing hole 521 to detect the profile of the fixing surface corresponding to the second fixing hole 521. If the profile of the fixing surface corresponding to the second fixing hole 521 meets the requirement, inserting the detection pin 321 into the second fixing hole 521, and if the detection pin can be inserted, judging that the position of the second fixing hole 521 is qualified; otherwise, judging that the product is unqualified.

Specifically, in the present embodiment, the detecting base 320 is mounted on the third supporting base 310 in an inverted manner. Meanwhile, the specific connection mode is as follows: the detecting seat 320 and the third supporting seat 310 are pivoted by the pin 530, so that the detecting seat 320 is turned over on the third supporting seat 310.

In one embodiment, referring to fig. 1, the rotating structure detecting system further includes a detecting instrument 400. The detecting instrument 400 is used to detect the surface profile of the rotating structure 500, so that the surface profile of the rotating structure 500 can be obtained by the detecting instrument 400.

It should be noted that the detecting instrument 400 may be a feeler gauge, a go-no-go gauge, a sine gauge, a height gauge, etc. Meanwhile, the surface profile degree is a main index for describing the dimensional accuracy of the curved surface, and is also a profile degree error which refers to the variation condition of the measured actual profile relative to the ideal profile.
