[0049] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0050] like Figure 1-7 As shown, according to an embodiment of the present application, a static balance detection device for a large rotating part is proposed, including: a wheel balancing shaft 100, the wheel balancing shaft 100 is used to detect the static balance qualification of the product wheel; a flange 200, the flange 200 is arranged on the wheel balancing shaft 100, and the product wheel is connected to the wheel balancing shaft 100 through the flange 200; a guide rail 300, the guide rail 300 is used to make the wheel balancing shaft 100 roll on the guide rail 300, and the static balance of the product wheel is judged by the running speed of the wheel balancing shaft 100.

[0051] The static balance detection device provided in the embodiment of the present application includes a wheel balancing shaft 100 , a flange 200 and a guide rail 300 .

[0052] The wheel balancing shaft 100 can roll on the guide rail 300 , and the flange 200 is installed on the wheel balancing shaft 100 . The flange 200 and the wheel balancing shaft 100 are concentrically arranged.

[0053] During use, the wheel of the product to be tested is concentrically fixed to the wheel balancing shaft 100 through the flange 200, and then the wheel balancing shaft 100 is rolled on the guide rail 300. If the wheel balancing shaft 100 can roll at a constant speed or decelerate uniformly on the guide rail 300, it can be judged that the static balance of the wheel of the product to be tested is qualified. If the wheel balancing shaft 100 rolls at a variable speed on the guide rail 300, it can be judged that the center of gravity of the wheel of the product to be tested is not at the center of the circle, and its static balance is unqualified.

[0054] This setting can determine the static balance of large rotating parts, such as product wheels. The judgment is stable and reliable, and the operation is simple. At the same time, the product wheel can be tested without lifting or other operations, avoiding the risk of large rotating parts falling off and effectively improving safety.

[0055] like Figure 1-7As shown, the wheel balancing shaft 100 includes: a rolling shaft 110 , wherein the rolling shaft 110 is used for rolling on the guide rail 300 ; a mounting plate 120 , and the flange 200 is connected to the rolling shaft 110 via the mounting plate 120 .

[0056] In this technical solution, the wheel balancing shaft 100 includes a rolling shaft 110 and a mounting plate 120, wherein the mounting plate 120 is specifically an annular plate, which is arranged on the rolling shaft 110. The center of gravity of the integral structure composed of the rolling shaft 110 and the mounting plate 120 is located on the center of gravity axis of the rolling shaft 110, so that the wheel balancing shaft 100 itself can roll at a uniform speed or roll at a uniform deceleration on the guide rail 300, thereby ensuring the reliability of the detection.

[0057] It is understandable that a circular opening is provided at the center of the product wheel, and the wheel balancing shaft 100 can pass through the circular opening, thereby fixing the product wheel to the middle section of the wheel balancing shaft 100.

[0058] like Figure 1-7 As shown, the wheel balancing shaft 100 also includes: reinforcing ribs 130, the mounting plate 120 is a circular metal part, and the mounting plate 120 is connected to the rolling shaft 110 through the reinforcing ribs 130; wherein, the number of the reinforcing ribs 130 is several, and they are arranged at equal angles along the outer surface of the rolling shaft 110 and the inner ring of the mounting plate 120.

[0059] In this technical solution, the wheel balancing shaft 100 further includes reinforcing ribs 130 , and the mounting plate 120 and the rolling shaft 110 are connected via the reinforcing ribs 130 . The reinforcing ribs 130 are arranged circumferentially along the rolling shaft 110 , and the angles between every two adjacent reinforcing ribs 130 are the same.

[0060] like Figure 1-7 As shown, the flange 200 is provided with a first stop; the mounting plate 120 is provided with a second stop; wherein, when the flange 200 is installed on the mounting plate 120, the first stop and the second stop are interference fit, and the flange 200 is connected to the mounting plate 120 by bolts.

[0061] In this technical solution, a first stop is provided on the flange 200, and a second stop is provided on the mounting plate 120. During the installation process, the first stop is first matched with the second stop, and then the flange 200 and the mounting plate 120 are connected by bolts to realize the connection between the flange 200 and the wheel balancing shaft 100. This setting increases the stability of the connection between the flange 200 and the wheel balancing shaft 100 and is easier to operate. At the same time, the first stop and the second stop are interference fit, which further increases the stability of the static balance detection device.

[0062] like Figure 1-7As shown, it also includes: a positioning groove 400, which is annular and is opened on both sides of the flange 200, and is used to position the product wheel when the product wheel is installed on the flange 200; the positioning groove 400 has multiple lines with different radii.

[0063] In this technical solution, the detection device also includes a positioning groove 400, which is specifically an annular groove formed in the flange 200. It is understood that the product disc is provided with a corresponding annular protrusion. During installation, the annular protrusion on the product disc can be aligned with the annular groove on the flange 200. The disc under test and the flange 200 are then fixed together using a bolt assembly, thereby achieving installation of the product disc under test and further improving the reliability of this product.

[0064] like Figure 1-7 As shown, it also includes: a lifting hole, which is opened on the flange 200.

[0065] In this technical solution, the flange 200 is provided with a number of lifting holes. When the detection device is set on the product wheel, the detection device can be hoisted and reversed through the lifting holes on the flange 200, which is convenient for the staff to perform assembly operations and further improves the usability of this product.

[0066] like Figure 1-7 As shown, it also includes: a stop block 500, which is set at the head and tail ends of the guide rail 300.

[0067] In this technical solution, the detection device also includes a stop block 500, which is respectively arranged at the head and tail ends of the two parallel guide rails 300 to prevent the wheel of the product being tested from rolling off the guide rail 300 from the head and tail ends of the guide rail 300. At the same time, during the product wheel test, the wheel of the product being tested that rolls to the end of the track is stopped to prevent the product wheel from rushing out of the track. This setting improves the safety during the static balance detection of large rotating parts and avoids the possibility of the wheel being tested rushing out of the track and injuring the staff.

[0068] like Figure 1-7 As shown, it also includes: a speed measuring component, which is used to detect the rotation speed of the wheel balance shaft 100.

[0069] In this technical solution, the detection device also includes a speed measuring component, which is used to measure the speed of the wheel balance shaft 100 and the product wheel rolling on the track. When the speed change meets the preset value, the static balance of the product wheel is qualified. When the speed change does not meet the preset value, the static balance of the product wheel is unqualified and needs to be adjusted.

[0070] This technical solution adds a speed measurement component to replace manual judgment, reduces the misjudgment rate, increases the accuracy of detection, and can effectively prevent unqualified rotating parts from being put into use.

[0071] like Figure 1-7 As shown, the speed measuring component includes: an infrared light emitting device, which is used to emit infrared light, and the infrared light is emitted to the wheel balance shaft 100; an infrared light receiving device, which is used to receive the infrared light reflected back by the wheel balance shaft 100; a processor, which is electrically connected to the infrared light emitting device and the infrared light receiving device; a display light, which is electrically connected to the processor; and an alarm, which is electrically connected to the processor.

[0072] In this technical solution, the speed measuring component includes an infrared light emitting device, an infrared light receiving device, a processor, a display light and an alarm, wherein the infrared light emitting device is used to emit infrared light, which is emitted to the wheel balance shaft 100 rolling on the track, and the infrared light receiving device is used to receive the infrared light reflected by the wheel balance shaft 100. The processor is electrically connected to the infrared light emitting device and the infrared light receiving device. The processor can calculate the rolling speed of the wheel balance shaft 100 based on the time difference between the infrared emitted light and the reflected light, and calculate the speed change of the wheel balance shaft 100 through the rolling speed of the wheel balance shaft 100, so as to determine whether the static balance of the product wheel is qualified. When the static balance of the wheel is qualified, the display light turns green, and when the static balance of the wheel is unqualified, the display light turns red and the alarm sounds an alarm.

[0073] This setting adds an alarm to strengthen the intensity of prompts when unqualified products appear, and further prevent unqualified rotating parts from being put into use.

[0074] like Figure 1-7 As shown, the wheel balancing shaft 100 further includes: guide rings, specifically two of which are embedded in the guide rail 300 when the rolling shaft 110 rolls on the guide rail 300 .

[0075] In this technical solution, the wheel balancing shaft 100 further includes a guide ring, which can prevent the wheel balancing shaft 100 from being deflected when rolling on the guide rail 300, thereby preventing the wheel balancing shaft 100 from derailing.
