DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Example 1

[0032] A ring-shaped magnetic block rotation drive assembly, such as Figure 1 , Figure 2As shown, it comprises a motor 1, a driving wheel 2 mounted on the output shaft of the motor 1, and a driven wheel 3 rotatably connected to the upper end cover 8 of the annular magnetic block integrated detection device through a positioning guide;

[0033] The driving wheel 2 and the driven wheel 3 are driven by a transmission member; specifically, the transmission member is a synchronous belt 9;

[0034] The middle part of the upper end surface of the driven wheel 3 is recessed downward to form a positioning step 5 for placing and positioning the annular magnet 4. The radius of the circle where the vertical annular surface of the positioning step 5 is located is slightly larger than the annular magnet 4. The annular magnet 4 can be conveniently placed on the positioning step 5. The horizontal plane of the positioning step 5 (the groove formed on the top of the driven wheel 3) is used for horizontal positioning of the annular magnet 4; the vertical annular surface of the positioning step 5 is used for radial positioning of the annular magnet 4. A step hole 6 is opened at the center of the positioning step 5. The step hole 6 is a through hole. The positioning ring 7 fixed below the annular magnet 4 is embedded in the step hole 6 so that the driven wheel 3 drives the annular magnet 4 to rotate under the action of friction.

[0035] The annular magnetic block rotation drive assembly drives the annular magnetic block 4 to rotate under the drive of the motor 1 and the transmission of the driving wheel 2 and the driven wheel 3. In addition, the rotation speed of the annular magnetic block 4 can be set by adjusting the rotation speed of the motor 1, thereby replacing manual rotation, improving the detection accuracy, and meeting the demand for fast performance and fast detection of batch annular magnetic blocks.

[0036] The driving method of the annular magnetic block rotation driving assembly is as follows: firstly, a positioning ring is adhered to the bottom of the annular magnetic block by strong glue; then, the positioning ring is embedded in the step hole; finally, a motor is turned on to drive the driving wheel and the driven wheel to rotate, thereby driving the annular magnetic block to rotate.

[0041] Specifically, the driving wheel 2 and the driven wheel 3 are driven by a synchronous belt 9; tooth grooves are provided on the outer walls of the driving wheel 2 and the driven wheel 3. Compared with gear transmission and chain transmission, synchronous belt transmission is more stable and has a smaller amplitude, which is conducive to improving the detection accuracy of the annular magnetic block.

[0042] Specifically, the positioning guide comprises an annular groove 11 formed on the lower end surface of the driven wheel 3 and three positioning pins 10 fixed on the upper end cover 8 of the annular magnetic block integrated detection device, and the three positioning pins 10 are evenly distributed. The three positioning pins 10 are inserted into the annular groove 11 at the same time, and the three positioning pins 10 are always located in the annular groove 11 during the rotation of the driven wheel 3, so as to position and guide the driven wheel 3.

The detailed structure of the ring-shaped magnet block comprehensive detection device is shown in the Chinese patent with the announcement number CN211014613U.

[0045] Specifically, the bracket includes a base 12 and a frame structure fixed on the base 12, and the frame structure includes a lower support plate 13 and an upper support plate 14; an opening consistent with the shape and size of the top of the annular magnetic block comprehensive detection device is opened in the middle of the upper support plate 13; the bottom of the annular magnetic block comprehensive detection device is fixed on the lower support plate 14, and the top of the annular magnetic block comprehensive detection device is flush with the upper support plate 13, forming a detection platform for convenient and quick detection.

[0046] Specifically, the motor 1 is fixed on the lower support plate 13 and is located on the lower surface of the lower support plate 13; the output shaft of the motor 1 is fixed on the upper support plate 14 through a bearing, the driving wheel 2 is fixed on the output shaft of the motor 1, and the driven wheel 3 is placed on the upper end cover 8 of the annular magnetic block comprehensive detection device; the positioning pin shaft 10 on the upper end cover 8 of the annular magnetic block comprehensive detection device is inserted into the annular groove 11 to position and guide the driven wheel 3.

[0047] Preferably, the bracket further includes an electric control cabinet 15 fixed on the base 12 and an industrial computer 16 installed in the electric control cabinet 15 .

[0048] Preferably, shock absorbers 17 are respectively installed on the four legs of the base 12 to prevent measurement deviation caused by vibration.

[0049] 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 scope of protection of the present invention.
