[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] Reference Figs. 1-3The utility model provides a kind of carbon fiber wheel rim true roundness measuring device, including support frame body 1, one side of support frame body 1 is inclinedly arranged, and the inclined surface of support frame body 1 is fixedly installed with operating base plate 2, and the surface of operating base plate 2 is respectively provided with guiding mechanism 3, tight positioning drive mechanism 4, auxiliary mechanism 5 of autorotation and true roundness detection mechanism 6.

[0024] In order to realize the action of guiding carbon fiber wheel rim under the autorotation of auxiliary mechanism 5, guiding mechanism 3 is provided, which includes a guide roller 31. The surface of operating base plate 2 is rotatably connected with a guide shaft 32 through a bearing. The circular surface of guide shaft 32 is fixedly installed with the surface of guide roller 31. The top of operating base plate 2 is also fixedly installed with supporting rods 33. The top of supporting rods 33 is in the shape of a circular arc. Four supporting rods 33 are symmetrically arranged. Carbon fiber wheel rim is placed on the circular surface of four supporting rods 33. The outer circular surface of carbon fiber wheel rim also contacts with the circular surface of guide roller 31.

[0025] Specifically, the design of guide roller 31 and guide shaft 32 can ensure that carbon fiber wheel rim maintains the correct position during autorotation, thereby realizing accurate guiding. The contact between guide roller 31 and the outer circular surface of the wheel rim can reduce the direct friction between the wheel rim and the supporting rods 33, reduce wear and tear, and prolong the service life of the equipment. The arrangement of guiding mechanism 3 simplifies the operation process. The operator can easily place the wheel rim on the supporting rods 33 and perform autorotation measurement.

[0026] In order to realize the action of positioning and tightening carbon fiber wheel rim during true roundness detection, tight positioning drive mechanism 4 is provided, which includes a guide rail 41. The guide rail 41 is installed on the surface of operating base plate 2. The surface of guide rail 41 is slidably connected with a sliding block 42. The surface of sliding block 42 is fixedly installed with a horizontal drive motor 43 and a vertical drive motor 44, respectively. The output end of horizontal drive motor 43 is fixedly installed with a horizontal rotating shaft 45 through a coupling. One end of horizontal rotating shaft 45 is fixedly installed with a power drive gear 46. One side of guide rail 41 is parallelly arranged with a rack 47. The rack 47 is installed on the surface of operating base plate 2. The teeth of rack 47 are engaged with the teeth of power drive gear 46.

[0027] Specifically, through the cooperation of horizontal drive motor 43 and vertical drive motor 44, the accurate tightening of the wheel rim can be realized, ensuring that the wheel rim maintains a stable shape and position during measurement. The vertical drive motor 44 can control the tightening force of the wheel rim, adapt to wheel rims of different sizes and models, and ensure that the tightening force is evenly distributed. The design of sliding block 42 allows tight positioning drive mechanism 4 to be flexibly adjusted to adapt to carbon fiber wheel rims of different sizes. Accurate tightening and positioning ensure the accuracy of the measurement results, which is particularly important for high-quality carbon fiber wheel rim production.

[0028] The output end of the vertical driving motor 44 is fixedly installed with a vertical rotating shaft 48 through a shaft coupling, the top end of the vertical rotating shaft 48 is fixedly installed with a rotating driving gear 49, the surface of the sliding block 42 is further rotationally connected with a tensioning shaft 410 through a bearing, the arc surface of the tensioning shaft 410 is fixedly installed with a tensioning wheel 411, the arc surface of the tensioning wheel 411 is in contact with the inner wall of the carbon fiber rim, and the top of the tensioning shaft 410 is fixedly installed with a driven gear 412, the gear slot of the driven gear 412 is engaged with the gear teeth of the rotating driving gear 49.

[0029] Specifically, the vertical driving motor 44 drives the vertical rotating shaft 48 to rotate, thereby realizing the rotation of the tensioning shaft 410 to drive the rotation of the tensioning wheel 411, and driving the carbon fiber rim to rotate in the detection to improve the measurement accuracy.

[0030] In order to realize the rotation of the carbon fiber rim in the detection of the true roundness, a rotation auxiliary mechanism 5 is arranged, which comprises an auxiliary limiting wheel 51, one side surface of the sliding block 42 is provided with an auxiliary sliding groove 52, the inner wall of the auxiliary sliding groove 52 is slidably inserted with an auxiliary sliding block 53, the top of the auxiliary sliding block 53 is fixedly installed with a mounting plate 54, the top of the mounting plate 54 is rotationally connected with an auxiliary rotating shaft 55 through a bearing, the arc surface of the auxiliary rotating shaft 55 is fixedly installed with the surface of the auxiliary limiting wheel 51, and the surface of the auxiliary limiting wheel 51 is in mutual extrusion with the outer arc surface of the carbon fiber rim.

[0031] Specifically, the mutual extrusion of the auxiliary limiting wheel 51 and the outer arc surface of the carbon fiber rim can ensure that the rim can rotate uniformly in the detection process, which is crucial for accurate measurement of the true roundness; since the rim can rotate uniformly, the measurement error caused by uneven rotation of the rim can be reduced, and the detection accuracy can be improved; by adjusting the position of the auxiliary sliding block 53, different diameters of the carbon fiber rim can be adapted, so that the mechanism has good universality.

[0032] The middle part of one side surface of the sliding block 42 is fixedly installed with a fixed block 56, the bottom of the auxiliary sliding block 53 is fixedly installed with a fixed shaft 57, the surface of the fixed shaft 57 is fixedly installed with a tension spring 58, and one end of the tension spring 58 is fixedly installed with the surface of the fixed block 56.

[0033] Specifically, the tension spring 58 can maintain the continuous contact pressure between the auxiliary sliding block 53 and the fixed block 56, ensure the stable sliding of the auxiliary sliding block 53 in the auxiliary sliding groove 52, and thus ensure the contact pressure between the auxiliary limiting wheel 51 and the carbon fiber rim; the elastic action of the tension spring 58 can absorb and buffer the vibration that may be generated in the rotation process of the rim, and improve the stability of the entire detection system.

[0034] In order to realize the action of automatically detecting the true roundness of the outer arc of the carbon fiber wheel rim, the true roundness detection mechanism 6 is provided, which includes a detection dial 61, and the top surface of the sliding block 42 is fixedly installed with a detection mounting block 62, the surface of the detection mounting block 62 is slidably connected with the top end arc shaft surface of the detection dial 61, and the detection dial 61 is fixedly installed by the rotating extrusion of the top screw on the top end arc shaft surface of the detection dial 61.

[0035] Specifically, the use of the detection dial 61 can directly measure the slight deviation of the outer arc of the wheel rim, thereby accurately evaluating the true roundness; the rotating extrusion of the top screw allows quick and accurate adjustment of the position of the detection dial 61 to adapt to wheel rims of different sizes; due to the fast and accurate measurement process, the detection speed of the wheel rim can be accelerated, thereby improving the overall production efficiency.

[0036] The design of the carbon fiber wheel rim true roundness measuring device first ensures the stability of the wheel rim during the measurement process through accurate guiding and tensioning positioning, significantly improving the measurement accuracy; secondly, the application of the rotation auxiliary mechanism 5 enables the wheel rim to rotate uniformly, effectively reducing measurement errors and improving the reliability of the detection results; thirdly, the setting of the true roundness detection mechanism 6 makes the measurement process fast and accurate, greatly improving the production efficiency; in addition, the universal design of the device enables it to adapt to carbon fiber wheel rims of different sizes, enhancing the applicability of the equipment; finally, by reducing direct friction and vibration, the service life of the equipment is prolonged and the maintenance cost is reduced. Overall, the device provides an efficient, accurate and reliable true roundness detection solution for carbon fiber wheel rim production, which is of great significance for improving product quality and promoting production automation.

[0037] Working principle: First, place the carbon fiber wheel rim to be measured on the detection platform and preliminarily position it through the auxiliary limiting wheel 51. Then, the sliding block 42 moves in the auxiliary sliding groove 52, causing the auxiliary sliding block 53 to move, thereby driving the mounting plate 54 and the auxiliary rotating shaft 55. The circular surface of the auxiliary rotating shaft 55 is fixedly connected with the auxiliary limiting wheel 51, so that the auxiliary limiting wheel 51 can tightly adhere to the outer arc surface of the carbon fiber wheel rim.

[0038] During the detection process, the auxiliary limiting wheel 51 exerts a certain pressure on the carbon fiber wheel rim, making it tightly adhere, ensuring that the wheel rim remains stable during rotation. At this time, the tensioning shaft 410 begins to rotate, driving the tensioning wheel 411 and the carbon fiber wheel rim to rotate together. Due to the extrusion of the auxiliary limiting wheel 51 and the outer arc surface of the wheel rim, the wheel rim always rotates uniformly during rotation, avoiding measurement errors caused by unbalanced rotation.

[0039] At the same time, the detection dial gauge 61 is in contact with the outer circular surface of the wheel rim for zero setting, and the true roundness value is judged by observing whether the parameter data of the detection dial gauge 61 changes.

[0040] The above merely describes a preferred specific implementation of the present application, but the scope of protection of the present application is not limited thereto, and any person skilled in the art, within the technical range disclosed by the present application, can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application, which should be covered within the scope of protection of the present application.
