Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, specifically to a tooling for measuring the distance between axles and motor cables. Background Technology

[0002] In the field of rail vehicle manufacturing and maintenance, measuring the spacing between the axle and motor cables is a crucial step in ensuring safe vehicle operation. A proper spacing prevents friction or interference between the cables and the rotating axle due to vibration, thermal deformation, or relative displacement during vehicle operation, thus preventing cable wear, short circuits, and other malfunctions. Currently, common measurement methods rely on manual indirect measurement using general-purpose measuring tools, which suffers from unstable positioning, inconvenient operation, and low efficiency, making it difficult to guarantee the accuracy and consistency of measurement results. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a fixture for measuring the distance between an axle and a motor cable, which can be quickly and stably installed on the axle and achieve efficient and reliable measurement.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a tooling for measuring the distance between an axle and a motor cable, comprising: a connecting part, the connecting part including an elastic strap and fixing members disposed on both sides of the elastic strap, the elastic strap being bound to the axle by the fixing members on both sides; a mounting base, the mounting base being fixedly disposed on the elastic strap and located in the middle therein, the mounting base having a slot extending to one side therein; and a measuring ruler, the measuring ruler including a slider and a fixed length ruler disposed on the slider, the slider being detachably disposed on the mounting base in cooperation with the slot.

[0005] Preferably, the fastener includes a button disposed on one side of the elastic strap and a plurality of buckle slots arranged in an array along the long side of the elastic strap, wherein the button cooperates with any of the buckle slots to allow the elastic strap to be fitted onto the axle.

[0006] Preferably, the surface of the elastic strap is provided with a friction-reducing layer to reduce the sliding friction between the elastic strap and the axle.

[0007] Preferably, a first magnetic block is embedded on the mounting base and on the bottom surface of the slot.

[0008] Preferably, the slot has an inverted T-shaped cross-section and is interference-fitted with the slider.

[0009] Preferably, the bottom surface of the slider is embedded with a second magnetic block that attracts the first magnetic block.

[0010] With the above structure, this utility model has the following advantages:

[0011] This application utilizes a fastener consisting of an elastic strap, a button, and a slot, which allows for quick binding to axles of different diameters. It is easily adjustable and adapts to the measurement needs of various axle specifications on-site. The measuring ruler can be quickly inserted and removed via a slider, allowing for the use of a fixed-length ruler of appropriate length to meet different standards. A friction-reducing layer lowers the sliding friction between the elastic strap and the axle, facilitating the elastic strap's rotation or axial movement along the axle to check whether the gap between the axle and the cable at different locations meets standard requirements. It is flexible, convenient, and efficient in use.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0020] Combined with appendix Figures 1-3 A fixture for measuring the distance between axles and motor cables, including a connector, a mounting base 3, and a measuring ruler.

[0021] The connecting part includes an elastic strap 1 and fixing members on both sides of the elastic strap 1, which bind the elastic strap 1 to the axle. The mounting base 3 is fixedly mounted on the elastic strap 1 and located in the middle. The mounting base 3 has a slot 4 extending to one side of it. The measuring ruler includes a slider 5 and a fixed length ruler 6 mounted on the slider 5. The slider 5 is detachably mounted on the mounting base 3 in cooperation with the slot 4.

[0022] In one embodiment of this utility model, the fastener includes a button 7 disposed on one side of the elastic strap 1 and a plurality of buckle slots 8 arranged in an array along the long side of the elastic strap 1. The button 7 cooperates with any of the buckle slots 8 to allow the elastic strap 1 to be fitted onto the axle. Specifically, as shown... Figure 2 As shown, the buckle slots 8 are opened at uniform intervals. The interval can be set to 10-15 mm according to the common axle diameter range. By selectively fastening the buttons 7 into the buckle slots 8 at different positions, the closed loop diameter formed by the elastic strap 1 can be easily adjusted, thereby firmly binding it to axles of different diameters and achieving quick installation and adaptation.

[0023] In one embodiment of this utility model, the surface of the elastic strap 1 is provided with a friction-reducing layer 2 to reduce the sliding friction between the elastic strap 1 and the axle. Specifically, as shown in... Figure 1 As shown, the friction-reducing layer 2 is a polytetrafluoroethylene coating or film applied to the inner surface of the elastic strap 1 (i.e. the side in contact with the axle), and its thickness is preferably 0.5 mm to 1 mm. This material has an extremely low coefficient of friction and good wear resistance, which can ensure that the tooling moves easily on the axle, thereby measuring the distance between the axle and the cable at different positions.

[0024] In one embodiment of this utility model, a first magnetic block 9 is embedded in the bottom surface of the mounting base 3 and the slot 4, and a second magnetic block 10 that engages with the first magnetic block 9 is embedded in the bottom surface of the slider 5. Specifically, as shown... Figures 2-3As shown, the first magnetic block 9 and the second magnetic block 10 are both made of permanent magnet material (such as neodymium iron boron). Their shapes match the receiving grooves on the bottom surface of the slot 4 and the slider 5. They are fixed and embedded by adhesive or pressing. When the slider 5 of the measuring ruler is inserted into the slot 4 along the opening side, the two magnetic blocks automatically attract each other under the action of magnetic force. This design provides the slider 5 with additional holding force, which can effectively prevent the measuring ruler from coming loose from the slot 4 during the measurement process or due to accidental contact, thus enhancing the reliability and safety of the tooling.

[0025] In one embodiment of this utility model, the slot 4 has an inverted T-shaped cross-section and is interference-fitted with the slider 5. Specifically, as shown... Figure 2 As shown, the cross-sectional shape of the slider 5 matches the inverted T-shaped slot 4, and the outer dimensions of the slider 5 are slightly larger than the inlet size of the slot 4, forming an interference fit. When the slider 5 is inserted from the side opening of the slot 4, a certain pushing force needs to be applied. The elastic deformation of the material is used to make the slider 5 smoothly snap into and fix it in the slot 4. This fit eliminates the assembly gap between the slider 5 and the mounting base 3, ensuring that the measuring ruler does not wobble after installation and maintains a stable vertical posture during the measurement process, thereby ensuring the accuracy of the measurement data.

[0026] In summary, this application discloses a fixture for measuring the distance between axles and motor cables that is easy to install, reliably positioned, and accurately measured. It adapts to different axle diameters through an elastic strap 1 and adjustable fasteners; utilizes a friction-reducing layer 2 to ensure quick and accurate positioning; employs an inverted T-groove and interference fit to achieve wobbly installation; and is further protected by a magnetic structure to prevent detachment. All these features ensure the fixture's high efficiency and reliability in practical use. The fixture has a reasonable structural design, clearly defined functions for each component, and its synergistic effect significantly improves the efficiency and accuracy of distance measurement in the manufacturing and maintenance of rail vehicles.

[0027] When using the tooling of this application, the elastic strap 1 is tied to the axle using a fastener. A fixed length ruler 6 of appropriate length is selected and installed on the mounting base 3. By pinching the mounting base 3, the elastic strap 1 is rotated or moved along the axle or its axial direction, so that the fixed length ruler 6 is placed between the axle and the closest point of the cable. If the fixed length ruler 6 touches the cable, it is unqualified; if it does not touch, it is qualified. Fixed length rulers of different lengths can be used according to different standards.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
