Description

Technical Field

[0001] The present application relates to the field of high-speed wheel damper mounting groove detection equipment, and in particular to a high-speed wheel damper mounting groove detection equipment. Background Art

[0002] The continuous development of high-speed railway technology has placed increasingly higher demands on the structural design and manufacturing precision of EMU wheels. In particular, EMU trailer wheels, with their complex structure and high precision, are key components in the EMU bogie and play a vital role in the performance and safety of the entire vehicle.

[0003] The main structure of a high-speed EMU trailer wheel consists of a rim, hub, and spokes. The rim is divided into an outer rim and an inner rim, the hub into an outer hub and an inner hub, and the spokes into an outer spoke and an inner spoke. In particular, a damper mounting groove is designed on the inner diameter of the inner rim for installing a damper to improve the wheel's shock absorption performance and operating stability.

[0004] The radial cross-section of the damper mounting slot is a dovetail structure, with a specific dovetail angle, slot width, slot depth, and a double-arc transition between the slot bottom and sidewalls. This complex slot structure not only increases the difficulty of machining but also greatly enhances the challenges of quality inspection.

[0005] Because the damper mounting slot is located on the inside of the wheel and its opening is close to the spoke, the limited space makes it difficult to quickly and easily inspect the damper using conventional testing equipment. Furthermore, due to the complex slot structure, including various contour features such as angles, dimensions, and arcs, there is currently no conventional, universal testing equipment on the market that can fully meet these inspection requirements. Utility Model Content

[0006] The purpose of this application is to provide a high-speed wheel damper mounting groove detection device that not only improves the accuracy and efficiency of detection, but also greatly reduces the difficulty of detection.

[0007] In order to achieve the above objectives, this application provides the following technical solutions:

[0008] A high-speed wheel damper mounting groove detection device includes a main body and at least one detection head. The detection head is arranged on one side of the main body. The outer contour of the detection head is the same as the contour of the mounting groove to ensure complete fit during detection. The thickness of the detection head is less than the height of the notch of the mounting groove to allow the detection head to be smoothly inserted into the notch of the mounting groove.

[0009] Furthermore, there are two detection heads, which are respectively arranged on both sides of the main body.

[0010] Furthermore, the two detection heads have different sizes.

[0011] Furthermore, a measuring device is included for measuring the gap between the detection head and the damper installation groove.

[0012] Furthermore, the main body and the detection head are both made of a material that is wear-resistant, corrosion-resistant and has a certain hardness.

[0013] Furthermore, the detection head is fixedly arranged on one side of the main body.

[0014] Furthermore, the detection head is detachably arranged on one side of the main body.

[0015] The beneficial effects of this application are:

[0016] During testing, the user holds the middle portion of the main body and places it horizontally into the damper mounting slot. Because the thickness of the test head is less than the height of the mounting slot opening, the test head can be smoothly inserted into the mounting slot opening. The main body is then rotated along its longitudinal centerline to a vertical position, thereby rotating the test head from a horizontal position to a vertical position within the mounting slot to detect whether the mounting slot's contour dimensions are acceptable. This application not only improves the accuracy and efficiency of testing, but also significantly reduces the difficulty of testing, providing a new solution for the machining and testing of EMU wheels.

[0024] 1. Main body; 2. Detection head; 3. Measuring device; DETAILED DESCRIPTION

[0025] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] A high-speed wheel damper Q mounting groove testing device, the mounting groove is in a dovetail groove shape, including a main body 1 and at least one detection head 2. The detection head 2 is arranged on one side of the main body 1. The outer contour of the detection head 2 is the same as the contour of the mounting groove F to ensure complete fit during testing. The thickness H1 of the detection head is less than the slot height H2 of the mounting groove F to allow the detection head to be smoothly inserted into the slot of the mounting groove.

[0027] The main body 1 can also be easily rotated or moved during inspection.

[0028] During testing, the middle part of the main body 1 is held and placed horizontally into the damper mounting slot F. Since the thickness of the detection head 2 of the present application is less than the slot height H2 of the mounting slot F, the detection head 2 can be smoothly inserted into the slot of the mounting slot F. The main body 1 is rotated along the longitudinal centerline of the main body to a vertical position, thereby rotating the detection head from a horizontal position to a vertical position in the mounting slot F to detect whether the outline dimensions of the mounting slot F are qualified. This application not only improves the accuracy and efficiency of testing, but also greatly reduces the difficulty of testing, providing a new solution for the processing and testing of EMU wheels.

[0029] In this embodiment, two detection heads 2 are provided, one on each side of the main body 1, to facilitate detection of different locations of the damper mounting slot FF. The two detection heads 2 can be of the same or different sizes to accommodate damper mounting slots F of different sizes and shapes.

[0030] In order to measure the gap W between the detection head 2 and the damper installation groove F, this embodiment further includes a measuring device 3 (not shown in the figure), which can be a feeler gauge or other tools that can accurately measure the gap.

[0031] Furthermore, the main body 1 and the detection head 2 are both made of a material that is wear-resistant, corrosion-resistant and has a certain hardness.

[0032] The detection head 2 is fixedly arranged on one side of the main body 1 and cannot be disassembled. This design simplifies the structure of the detection device and reduces the manufacturing cost.

[0033] The detection head 2 is detachably mounted on one side of the main body 1. This design allows the detection head 2 to be replaced or adjusted as needed to accommodate damper mounting slots F of varying sizes and shapes. In this embodiment, the detection head 2 is secured to the main body 1 via a threaded, snap-fit, or other removable connection. When the detection head 2 needs to be replaced, it can be easily removed and replaced by simply loosening the connector.

[0034] like Figure 3 As shown, the specific detection method is:

[0035] (S1) Before testing, the instrument and the high-speed wheel damper are subjected to the same temperature treatment.

[0036] (S2) Figure 3 As shown in (a), hold the middle part of the main body 1 and place the detection head 2 (first use the maximum size of the drawing to design the detection head 2) horizontally into the damper installation groove F.

[0037] like Figure 3 As shown in (b) to (c), gently rotate the main body 1 to try to rotate the detection head 2 in the installation groove F from the horizontal state to the vertical state.

[0038] (S3) Maximum design dimension of the test head 2: If the test head 2 cannot rotate smoothly during the rotation process, that is, there is a jamming phenomenon, it means that the outline dimension of the damper installation groove F does not exceed the design upper limit, and it is judged to be a qualified product.

[0039] The profile of the test head 2 is scaled down to the same proportions as the design dimensions of the damper mounting slot F. This design ensures that the test head 2 can smoothly enter the testing area even when the product is at its minimum size. During use, the profile of the test head 2 is brought into contact with and compared to the profile of the mounting slot F. The degree of conformity between the test head 2 and the profile of the mounting slot F determines whether the product meets the design requirements and, therefore, its acceptance.

[0040] Since the size of the detection head 2 is obtained by proportionally reducing the design size of the damper installation groove F of the product, the accuracy of the detection can be ensured.

[0041] Through simple contact comparison, it is possible to quickly determine whether the tested product is qualified, thereby improving detection efficiency.

[0042] The design principle and use method of the detection head 2 are applicable to various occasions requiring detection of contour dimensions and have wide versatility.

[0043] If the detection head 2 can be smoothly rotated into the installation groove F, the gap is detected using a measuring device, i.e., a feeler gauge, according to the reserved gap, and whether the installation groove F is qualified is determined based on the size of the feeler gauge.
