[0025] like Figures 2 to 3 As shown, the positioning column 2 includes: a column 3; a groove 4, which is opened on the top of the column 3; a first elastic member 5, which is installed at the bottom of the groove 4; a transmission rod 6, which is installed on the first elastic member 5 and is configured to press the transmission rod 6 downward to shrink the first elastic member 5; the positioning column 2 plays a precise guiding and positioning role, ensuring that the position of the brake disc on the fixed base 1 is relatively accurate, preparing for subsequent fixation and detection.

[0026] like Figures 2 to 5 As shown, the abutment portion includes: multiple groups of through grooves 7, which are evenly opened on the bottom side wall of the positioning column 2, and the multiple groups of through grooves 7 are connected to the groove 4; multiple groups of rotating shafts 8, each group of through grooves 7 has a group of rotating shafts 8 installed on the bottom wall; multiple groups of rotating frames 9, each group of through grooves 7 has a group of rotating frames 9 installed in it, and it is configured that when the rotating frame 9 rotates toward the outside of the positioning column 2, it passes through the through grooves 7 and leaves the positioning column 2.

[0027] like Figures 4 to 5 As shown, the rotating frame 9 includes: a frame body 10; a storage slot 11, which is opened on the frame body 10; an electric push rod 12, which is installed in the storage slot 11 and is configured so that when the rotating frame 9 rotates and leaves the positioning column 2, the electric push rod 12 extends in a direction away from the positioning column 2.

[0028] Embodiment 2: Figures 4 to 5 As shown, the buckle portion includes: a snap-fitting member 13, which is located in the groove 4 and above the through groove 7; a hook member 14, which is located on the rotating frame 9 and is configured so that when the rotating frame 9 rotates toward the positioning column 2 and enters the through groove 7, the hook member 14 engages with the snap-fitting member 13 to keep the rotating frame 9 fixed; the hook member 14 is slidably connected to the rotating frame 9; a push block 15, which is installed on the transmission rod 6 and is configured so that when the transmission rod 6 squeezes the first elastic member 5 downward, the transmission rod 6 drives the push block 15 to squeeze the hook member 14 downward to release the engagement between the hook member 14 and the snap-fitting member 13.

[0029] like Figure 5As shown, it also includes: a slide groove 16, which is opened on the rotating frame 9; a sliding block, which is located in the slide groove 16, and one side of the sliding block is connected to the hook member 14; a second elastic member 18, which is installed in the slide groove 16 and is located at the bottom end of the sliding block.

[0030] like Figure 3 As shown, it also includes: a limiting rod 19, which is located in the positioning column 2 and connected to the transmission rod 6, and is used to keep the transmission rod 6 moving vertically upward or downward.

[0031] like Figure 2 As shown, it also includes: a driving part 20, which is located in the fixed base 1 and is used to drive the positioning column 2 to rotate so as to adjust the position of the release of the abutment part; the driving part 20 adopts a driving motor, and the output end of the driving motor is connected to the positioning column 2, which is used to drive the positioning column 2 to rotate, so as to change the position of the release rotating frame 9, thereby adapting to the middle structure of more types of brake discs.

[0032] The technical solution provided by the utility model is that when the device is in the initial state, at this time, the column 3 of the positioning column 2 stands upright on the fixed base 1, the transmission rod 6 is in a normal position under the support of the first elastic member 5, and the multiple groups of rotating frames 9 of the abutment portion are located inside the positioning column 2 and fixed by the snap action of the snap-fit ​​portion, the middle of the brake disc is aligned with the top of the positioning column 2, and then the brake disc is slid downward along the positioning column 2. Since the shape and size of the positioning column 2 are adapted to the middle of the brake disc, the brake disc can accurately slide from the top of the positioning column 2 to the bottom, and finally fall on the fixed base 1; then the brake disc is fixed, and when the brake disc reaches the fixed base 1, the brake disc needs to be fixed to prevent displacement during the detection process. At this time, by pressing the transmission rod 6, the transmission rod 6 presses the first elastic member 5 downward, the first elastic member 5 contracts, and the push block 15 on the transmission rod 6 moves downward with the transmission rod 6. The push block 15 presses the hook member 14 of the buckle portion downward, and the hook member 14 is slidably connected with the rotating frame 9. The hook member 14 on the rotating frame 9 overcomes the elastic force of the second elastic member 18 under the pressure of the push block 15, and slides downward along the slide groove 16, so that the hook member 14 and the clamping member 13 are disengaged. Since the clamping of the buckle portion is released, the multiple groups of rotating members of the abutment portion The frame 9 rotates toward the outside of the positioning column 2 with the rotating shaft 8 on the bottom wall of the through slot 7 as the axis under the action of its own gravity or other external forces (such as slight spring force, etc.). When the rotating frame 9 rotates to a certain extent, the electric push rod 12 extends, thereby abutting against the center of the brake disc, so that the brake disc is firmly fixed on the fixed base 1, ensuring that the brake disc remains stable during the detection process. After the brake disc is fixed, the detection equipment can perform processing accuracy detection on the brake disc, such as detecting the flatness, thickness deviation and other parameters of the brake disc. Since the brake disc is firmly fixed on the fixed base 1, it will not be displaced during the detection process, which can ensure the detection The accuracy of the test results; in addition, when the test is completed, the brake disc needs to be removed. First, the rotating frame 9 is rotated back into the through slot 7 to restore the rotating frame 9 to its initial position. In the process of the rotating frame 9 entering the through slot 7, the hook member 14 on the rotating frame 9 and the clamping member 13 in the groove 4 will re-engage. Because the hook member 14 slides upward and returns to its initial position under the action of the second elastic member 18, the rotating block remains fixed inside the positioning column 2. As the abutment portion returns to its initial retracted state, the brake disc is no longer fixed by the abutment portion and can be easily removed from the fixed base 1, completing the operation cycle of the entire testing process.

[0033] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
