DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

Therefore, they cannot be understood as limitations on the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figures 1 to 4 As shown, the utility model provides a wear measuring device, which is mainly used for measuring the wear of the oil deflector ring after the gearbox of a rail transit vehicle is disassembled. During the actual use of the oil deflector ring, a circle of scratches will be formed on the outer surface of the oil deflector ring due to wear. The measuring device detects the wear of the circle of scratches. The measuring device and the oil deflector ring need to rotate 360° relative to each other to obtain the wear data. Therefore, the method used to measure the wear of the oil deflector ring is to select a measuring position on the circumference of the oil deflector ring, use the measuring device to move 360° along the circumference of the oil deflector ring at the selected measuring position, and then obtain the wear depth of the oil deflector ring, determine whether its wear depth exceeds the set standard value, and further determine whether the oil deflector ring needs to be replaced.

[0033] like Figures 1 to 4 As shown, in this embodiment, the measuring device includes a measuring unit (not shown in the figure) and a fixing unit for fixing the oil retaining ring to be measured (not shown in the figure), wherein the measuring unit can adopt a measuring device used in the prior art to measure the wear amount of the oil retaining ring.

[0034] The fixing unit includes a support seat 1, a rotating mechanism 2 and a fixing device 3. The rotating mechanism 2 is fixedly mounted on the support seat 1. The fixing device 3 is connected to the rotating mechanism 2 and rotates driven by the rotating mechanism 2. The oil retaining ring to be tested is mounted on the fixing device 3.

[0035] By adopting the above structure, the measurement personnel can fix the oil deflector ring on the device, which is convenient for the measurement personnel to find the measurement position accurately. At the same time, the oil deflector ring can be rotated 360° through the rotating mechanism 2. The wear amount at the scratch position of a circle of the oil deflector ring can be obtained by using the measuring unit. The operation is simple and convenient, and there will be no shaking or deviation during the detection process, thus ensuring the accuracy of the measurement data and avoiding errors caused by inaccurate measurement that may lead to distortion of the measurement results and create driving safety hazards.

[0036] In this embodiment, preferably, the fixing device 3 includes a fixing disk 31 and a clamping mechanism 32, the fixing disk 31 is connected to the rotating mechanism 2, the fixing disk 31 is driven to rotate by the rotating mechanism 2, the clamping mechanism 32 is installed on the fixing disk 31, the clamping mechanism 32 adopts a structure with adjustable clamping spacing, and the oil retaining ring to be measured is clamped and fixed by the clamping mechanism 32. In this way, the fixing device 3 can clamp oil retaining rings of different specifications and sizes, and then the device can be used to measure the wear of oil retaining rings of different inner diameters, thereby improving the versatility of the measuring device and facilitating the improvement of measurement efficiency.

[0037] With respect to the clamping mechanism 32, it is further preferred in this embodiment that the clamping mechanism 32 includes at least two movable clamping arms 321 that move radially along the fixed disk 31, and a driving mechanism that drives the movable clamping arms 321 to move. In order not to affect the wear amount of the scratch position measured by the measuring unit along the outer peripheral surface of the oil deflector ring, it is further preferred that the movable clamping arm 321 cooperates with the inner ring surface of the oil deflector ring to clamp and fix the oil deflector ring by applying force from the inside to the outside. The movable clamping arm 321 can adjust the clamping distance by moving radially to adapt to clamping oil deflector rings of different inner diameters.

[0038] There may be two or three movable clamping arms 321. In order to simplify the structure of the device, in this embodiment, it is further preferred that two movable clamping arms 321 are symmetrically arranged in the radial direction of the fixed plate 31, and the center lines of the two movable clamping arms 321 coincide with each other.

[0039] The driving mechanism preferably adopts a screw 322, and the two movable clamping arms 321 are respectively threadedly connected to the screw 322, and the movement directions of the two movable clamping arms 321 are opposite. Rotating the screw 322 can make the two movable clamping arms 321 move synchronously toward the center of the circle to reduce the clamping distance, which is suitable for oil retaining rings with small inner diameters, and can also move synchronously outward to increase the clamping distance, which is suitable for oil retaining rings with large inner diameters.

[0040] The movable clamping arms 321 adopt the above-mentioned structure, which is conducive to simplifying the overall structure of the device and is easy to operate. The operator only needs to rotate the screw 322 to adjust the clamping distance of the two movable clamping arms 321 and clamp the two movable clamping arms 321 on the oil retaining rings with different inner diameters.

[0041] In this embodiment, in order to install the screw rod 322, a through hole (not shown in the figure) extending in the radial direction is provided inside the fixed disk 31, and the screw rod 322 passes through the through hole. Two grooves 311 recessed from the outer circumference to the center of the circle are provided radially symmetrically on the fixed disk 31, and two movable clamping arms 321 are embedded in the grooves 311 and move along the grooves 311. The depth of the grooves 311 limits the minimum clamping distance of the movable clamping arms 321. One end of the movable clamping arm 321 has a threaded hole (not shown in the figure) threadedly connected with the screw rod 322, and the other end passes through the groove 311 and protrudes from the outer surface of the fixed disk 31. The width of the groove 311 matches the width of the movable clamping arm 321, and the movable clamping arm 321 and the groove 311 are clearance-matched. In this way, it can not only ensure that the movable clamping arm 321 slides smoothly in the groove 311, but also play a certain guiding and supporting role for the movable clamping arm 321.

[0042] An operating handle (not shown in the figure) is also installed at one end of the screw rod 322 to facilitate the measurement personnel to rotate the screw rod 322 to adjust the clamping distance between the two movable clamping arms 321.

[0043] In order to make the clamping between the movable clamping arm 321 and the inner circumferential surface of the oil detent ring more stable, it is further preferred that the outer side surface of the movable clamping arm 321 (i.e. the side facing the inner ring surface of the oil detent ring) is an arc surface, so as to increase the contact area with the inner ring surface of the oil detent ring, thereby ensuring that the oil detent ring can be firmly fixed during the measurement process, ensuring the measurement accuracy, and also helping to further improve the measurement efficiency.

[0044] In this embodiment, the rotating mechanism 2 includes a base 21, a bearing 22, a rotating shaft 23 and a rotating disk 24. The base 21 is fixed on the support base 1. The base 21 has a bearing hole (not shown in the figure), and the bearing 22 is installed in the bearing hole. One end of the rotating shaft 23 is fixedly connected to the rotating disk 24, and the other end is fixedly connected to the bearing 22. The fixed disk 31 in the fixing unit 3 is fixedly installed on the rotating disk 24 by bolts, and the fixed disk 31 and the rotating disk 24 are integrated into an integral structure. In this way, it can be ensured that the rotating shaft 23 drives the rotating disk 24 to rotate smoothly, thereby ensuring that the fixed disk 31 and the oil retaining ring installed on the fixed disk 31 rotate smoothly and stably.

[0045] In this embodiment, the main body of the base 21 is a cylindrical structure, with mounting seats 211 extending outward on both sides of the main body. The mounting seats 211 on both sides are respectively provided with mounting holes, and are fixed to the top of the support seat 1 by bolts 212.

[0046] In this embodiment, it is further preferred that the rotating mechanism 2 further includes an adjusting member 25, which is movably mounted on the base 21, and the top of the adjusting member 25 passes through the base 21 and abuts against the inner ring of the bearing 22. The rotation speed of the rotating shaft 23 and the rotating disk 24 is adjusted by adjusting the contact degree between the adjusting member 25 and the inner ring of the bearing 22, thereby adjusting the rotation speed of the oil retaining ring during the measurement process. In this way, it is convenient for the measurement personnel to adjust the rotation speed of the oil retaining ring during the measurement process according to the actual measurement requirements, which is conducive to further improving the accuracy of the measurement.

[0047] Among them, the adjusting member 25 is further preferably a screw, a handle 26 is installed at the end of the adjusting member 25, a threaded hole is set on the main body of the base 21, the adjusting member 25 is connected to the base 21 through a thread, and the operating handle 26 can rotate the adjusting member 25 to make the adjusting member 25 move radially along the bearing 22.

[0048] In this embodiment, the support seat 1 includes a base 11 and a support frame 12, and the support frame 12 is vertically installed on one side of the base 11. Among them, the base 11 and the support frame 12 are both cast iron structures. The base 11 adopts a square frame structure to ensure that it is stably fixed on the working platform, and the support frame 12 adopts a trapezoidal structure to improve its supporting capacity. This structure can greatly improve the supporting capacity of the entire support seat 1 while reducing the weight, and ensure the stability and strength of the overall structure of the measuring device. The base 11 and the support frame 12 can also adopt other shapes as long as they can meet the supporting strength and stability of the rotating mechanism 2 and the fixing device 3.

[0049] There are multiple threaded holes on the top of the support frame 12, which match the mounting holes on the base 21. The base 21 is fixed to the support frame 12 by bolts, and the fixation is guaranteed to be firm and reliable.

[0050] The angle between the rotation center line of the rotating mechanism 2 and the plane of the base 11 is 0-90°, and the angle of the angle can be determined according to the measurement requirements. In the present embodiment, the preferred angle is 0°, that is, the rotation center line of the rotating mechanism 2 is parallel to the plane of the base 11, and the oil deflector rotates in a vertical plane after being clamped. The angle can also be 90°, that is, the rotation center line of the rotating mechanism 2 is perpendicular to the plane of the base 11, and the oil deflector rotates in a horizontal plane after being clamped. Of course, the angle can also be other angles, so that the oil deflector is in a tilted state relative to the base 11 after installation.

[0051] The measuring unit includes a measuring device, and the measuring device can be any measuring device in the prior art. In this embodiment, in order to reduce the labor intensity of the measuring personnel, it is further preferred that a mounting frame (not shown in the figure) is installed on the support seat 1, and the measuring device is installed on the mounting frame. The mounting frame extends vertically upward from the base 11, and the top of the mounting frame can adopt an adjustment structure, such as a telescopic arm structure, which is used to adjust the measuring position of the measuring device according to the installed oil deflector ring, so that the measuring head in the measuring device is just placed at the scratch position to be measured. At this time, it is only necessary to rotate the oil deflector ring to obtain the measurement data.

[0052] In the structure of the support base 1, the support frame 12 is vertically mounted on one side of the base 11, which can provide the required installation space for the mounting frame and the measuring equipment, making the entire measuring device more compact and occupying less space.

[0053] The following describes in detail the steps for using the measuring device:

[0054] 1. First place the measurement on the working platform.

[0055] 2. Rotate the screw 322 in the clamping mechanism 32 to move the two movable clamping arms 321 toward the center of the circle, place the oil deflector ring on the fixed plate 31, and then rotate the screw 322 in the opposite direction to make the two movable clamping arms 321 apply force from inside to outside to clamp and fix the oil deflector ring.

[0056] 3. Install the measuring device on the mounting bracket and adjust it to the measuring position on the oil retaining ring.

[0057] 4. The operator rotates the rotating mechanism 2 to make the oil deflector ring rotate at least one circle, thereby obtaining the wear data at the scratch position. During this process, the measurement personnel can adjust the adjustment member 25 according to the measurement needs to change the rotation speed of the oil deflector ring.

[0058] From the above description, it can be seen that the measuring device has the following technical effects:

[0059] 1. The measuring device uses a rotating mechanism and a fixing device, which can not only facilitate the measuring personnel to accurately find the measuring position, but also fix and rotate the oil retaining ring to be measured, so as to accurately measure the wear data of the scratch position on the oil retaining ring, ensure the accuracy of the data, avoid the error caused by inaccurate measurement, lead to distortion of the measurement results, and cause hidden dangers to driving safety.

[0060] 2. The measuring device has a simple structure and is reliable and stable to use. It can meet the wear measurement requirements of the oil retaining ring during maintenance and ensure the reliability of the oil retaining ring maintenance of rail vehicles.

[0061] 3. The measuring device has strong versatility and can be applied to the wear measurement of oil retaining rings with different inner diameters.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents suggested above without departing from the scope of the technical solution of the present invention.
