[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a tooling fixture for measuring the diameter of a rotating body. (Refer to...) Figure 1 and Figure 2 A tooling fixture for measuring the diameter of a rotating body includes a housing 1, a clamping assembly 2 inside the housing 1, a first scale 3 penetrating through the top of the housing 1, the surface of the first scale 3 being slidably connected to the housing 1, the first scale 3 being used in conjunction with the clamping assembly 2, and a limiting mechanism 4 inside the housing 1 being used in conjunction with the clamping assembly 2.

[0027] The clamping assembly 2 includes an arc-shaped base 21 fixedly installed inside the housing 1. An electric push rod 22 is fixedly installed on the top of the housing 1. The telescopic end of the electric push rod 22 passes through the housing 1 and is slidably connected to the housing 1. An arc-shaped pressure plate 23 is fixedly connected to the telescopic end of the electric push rod 22. The arc-shaped pressure plate 23 is used in conjunction with the arc-shaped base 21. The top of the arc-shaped pressure plate 23 is fixedly connected to the bottom of the first scale 3. When the top of the arc-shaped pressure plate 23 overlaps with the bottom of the arc-shaped base 21, the value of the exposed part of the first scale 3 is 0.

[0028] When it is necessary to measure the diameter of the rotating body, the rotating body is placed on the arc-shaped pressure plate 23, and the other side of the rotating body is supported by the limiting mechanism 4, so that one side of the rotating body is flush with one side of the arc-shaped base 21. Then, the arc-shaped pressure plate 23 is moved downward by the electric push rod 22, so that the arc-shaped pressure plate 23 presses against the top of the rotating body, thereby clamping the rotating body between the arc-shaped pressure plate 23 and the arc-shaped base 21. When the arc-shaped pressure plate 23 moves, it will drive the first scale 3 to move at the same time. When the arc-shaped pressure plate 23 stops moving, the remaining part of the first scale 3 is the diameter of the rotating body.

[0029] Reference Figure 1 and Figure 2A support rod 24 is fixedly connected to the surface of the arc-shaped pressure plate 23. A support groove 25 is opened on the inner wall of the housing 1. One end of the support rod 24 is slidably connected to the inside of the support groove 25. A positioning rod 26 is fixedly connected to the inside of the support groove 25. The positioning rod 26 passes through the support rod 24 and is slidably connected to the support rod 24. By sliding one end of the support rod 24 to the inside of the support groove 25 and stabilizing the position of the support rod 24 inside the support groove 25 through the positioning rod 26, the position of the arc-shaped pressure plate 23 is effectively stabilized, avoiding the arc-shaped pressure plate 23 from shifting and affecting the clamping work and measurement accuracy.

[0030] Reference Figure 2 and Figure 3 The limiting mechanism 4 includes a limiting plate 41 slidably connected inside the housing 1. A groove 42 is provided on the top of the limiting plate 41. A slider 43 is fixedly installed inside the housing 1. The inner cavity of the groove 42 is slidably connected to the surface of the slider 43. An adjusting component 46 is fixedly connected to one side of the housing 1. The adjusting component 46 is connected to the limiting plate 41 in a transmission manner. The position of the limiting plate 41 is adjusted by the adjusting component 46, and the position of the limiting plate 41 is stabilized by the slider 43 and the groove 42, so as to avoid the limiting plate 41 from shifting. Thus, the limiting plate 41 can limit and support the rotating body.

[0031] Reference Figure 2 and Figure 3 A limiting block 44 is fixedly installed on the surface of the slider 43, and a limiting groove 45 is opened in the inner wall of the slide groove 42. The surface of the limiting block 44 is slidably connected to the inner cavity of the limiting groove 45. By sliding the surface of the limiting block 44 to the inner cavity of the limiting groove 45, the connection between the slider 43 and the slide groove 42 can be effectively stabilized, and the slider 43 and the slide groove 42 can be prevented from separating and affecting the position of the limiting plate 41.

[0032] Reference Figure 2 and Figure 4 The adjusting component 46 includes a sleeve 4601, which is fixedly connected to one side of the housing 1. A threaded sleeve 4602 is fixedly connected to one side of the limiting plate 41. One end of the threaded sleeve 4602 extends into the interior of the sleeve 4601 and slides in connection with the inner cavity of the sleeve 4601. A threaded rod 4603 is rotatably connected inside the sleeve 4601, and one end of the threaded rod 4603 is threaded into the interior of the threaded sleeve 4602. By rotating the threaded rod 4603, the threaded rod 4603 drives the threaded sleeve 4602 to move laterally, so that the threaded sleeve 4602 drives the limiting plate 41 to move simultaneously. Thus, the adjusting component 46 achieves the function of adjusting the position of the limiting plate 41.

[0033] Reference Figure 2 and Figure 4A positioning block 4604 is fixedly installed on the surface of the threaded rod 4603, and a positioning groove 4605 is provided on the inner wall of the sleeve 4601. The surface of the positioning block 4604 is slidably connected to the inner cavity of the positioning groove 4605. By sliding the surface of the positioning block 4604 to the inner cavity of the positioning groove 4605, the sleeve 4601 stabilizes the position of the threaded rod 4603 through the positioning block 4604 and the positioning groove 4605, and avoids the threaded rod 4603 from moving laterally and affecting the position of the threaded sleeve 4602 and the limiting plate 41.

[0034] Reference Figure 1 and Figure 2 The top of the housing 1 has an opening 5, and a marker 6 is fixedly installed on the top of the limiting plate 41. The top of the marker 6 passes through the opening 5 and is slidably connected to the inner cavity of the opening 5. A second ruler 7 is fixedly installed on the top of the housing 1. The marker 6 and the second ruler 7 are used in conjunction. The value of the second ruler 7 is the minimum value of the length of the arc-shaped base 21 and the arc-shaped pressure plate 23. The farther the limiting plate 41 is from the arc-shaped base 21 and the arc-shaped pressure plate 23, the larger the value indicated by the marker 6. When the position of the limiting plate 41 is adjusted, the marker 6 moves simultaneously with the limiting plate 41. When the limiting plate 41 stops moving, the value on the second ruler 7 indicated by the marker 6 is the length of the rotating body.

[0035] Working principle: When measuring the diameter of a rotating body, the housing 1 is placed in the desired position, and then the rotating body is placed on the arc-shaped pressure plate 23. The threaded rod 4603 is rotated, and the surface of the positioning block 4604 slides into the inner cavity of the positioning groove 4605 to stabilize the position of the threaded rod 4603 inside the sleeve 4601, preventing lateral movement of the threaded rod 4603. This allows the threaded rod 4603 to drive the limiting plate 41 to move laterally through the threaded sleeve 4602. When the limiting plate 41 moves, the surface of the limiting block 44 slides into the inner cavity of the limiting groove 45 to stabilize the connection position between the slide groove 42 and the slider 43, thereby stabilizing the position of the limiting plate 41. The limiting plate 41 then supports and limits the other side of the rotating body, ensuring that one side of the rotating body is aligned with the arc-shaped base 21. One side is flush with the limit plate 41, and when the limit plate 41 moves, it causes the scale 6 to slide inside the opening 5. When the limit plate 41 stops moving, the value on the second scale 7 pointed to by the scale 6 is the length of the rotating body. After the rotating body is limited, the arc-shaped pressure plate 23 is driven to move downward by the electric push rod 22, and is slidably connected to the inside of the support groove 25 by the support rod 24. The positioning rod 26 prevents the support rod 24 from separating from the support groove 25, so that the arc-shaped pressure plate 23 can move downward smoothly, thereby clamping the rotating body between the arc-shaped pressure plate 23 and the arc-shaped base 21. When the arc-shaped pressure plate 23 moves, it will drive the first scale 3 to move at the same time. When the arc-shaped pressure plate 23 stops moving, the remaining part of the first scale 3 is the diameter of the rotating body, thereby completing the measurement of the diameter of the rotating body and the measurement of the length of the rotating body at the same time.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
