Description

Technical Field

[0001] This utility model relates to the field of vehicle coupling technology, specifically to a coupler alignment device. Background Technology

[0002] Before vehicle assembly, the coupler needs to be near the center for smooth coupling. This usually requires the coupler axis to be as parallel as possible to the vehicle axis, meaning the coupler must be aligned before coupling. However, some existing couplers lack a centering function, requiring workers to manually swing the coupler to the center position before coupling, such as the E4881AE coupler and No. 16 coupler, which is inconvenient. Some couplers use a mechanical swing arm centering device, requiring sufficient swing margin during coupling, making it difficult to guarantee centering accuracy, such as the CA-3 coupler and No. 15 coupler. In addition, some couplers lack a separate centering mechanism, instead using a centering shoulder structure at the rear of the coupler, relying on the friction between the front plate and the rear of the coupler to achieve centering. Friction occurs during the swinging process, requiring workers to weld and repair the rear of the coupler after long-term use, which is a significant workload, such as the F-type coupler and No. 17 coupler.

[0003] Therefore, it is necessary to provide a coupler alignment device to solve the problems mentioned in the background art. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a coupler centering device, comprising: a first centering component and a second centering component, wherein the first centering component and the second centering component are disposed on the vehicle body and symmetrically installed on both sides of the coupler, for limiting and straightening the two sides of the coupler;

[0005] The first centering component and the second centering component are both hinged to each other on their adjacent sides. The other end of each of the connectors is hinged to the vehicle body. The first centering component or the second centering component, the connector, and the mounting surface of the vehicle body form a triangular support structure.

[0006] The first and second centering components are provided with wear blocks at the hinge ends of the connector, and the wear blocks are arranged facing each other to support and guide the two sides of the coupler.

[0007] Preferably, both the first centering component and the second centering component include: an elastic support member, one end of which is provided with the wear block and the connector, and the other end of which is provided with a fixing seat; the fixing seat is connected to the vehicle body by bolts.

[0008] Preferably, the elastic support includes: a pressure rod, a limiting ring plate is provided at one end of the pressure rod near the wear block and the connector, the other end of the pressure rod is slidably fitted with the fixing seat, and a spring is fitted on the pressure rod, the spring being elastically supported between the limiting ring plate and the fixing seat.

[0009] Preferably, the end of the pressure rod near the fixed base is a screw structure, and an adjusting nut is screwed onto the screw. The adjusting nut is located on the side of the fixed base away from the spring and is used to adjust the compression of the spring.

[0010] Preferably, the wear block is made of nylon material.

At the same time, wear blocks, springs, pressure rods, and adjusting nuts are provided. The adjusting nuts are used to pre-tighten the springs, so that the wear blocks are pressed against the side of the coupler under the action of the springs, keeping the coupler in the center position. When the wear blocks wear out, the pre-tightening amount of the adjusting nuts can be reduced to keep the wear blocks pressed against the coupler, thereby improving the service life of the wear blocks.

[0020] Please see Figure 1-3 This utility model provides a coupler centering device, including: a first centering component 1 and a second centering component 2. The first centering component 1 and the second centering component 2 are disposed on the vehicle body and symmetrically installed on both sides of the coupler, for limiting and straightening the two sides of the coupler.

[0021] The first centering component 1 and the second centering component 2 are both hinged to one end of each other. The other end of each of the connecting components 3 is hinged to the vehicle body. The first centering component 1 or the second centering component 2, the connecting component 3 and the mounting surface of the vehicle body form a triangular support structure.

[0022] The first centering component 1 and the second centering component 2 are provided with wear blocks 4 at the hinge ends of the connector 3. Each wear block 4 is arranged facing each other and is used to support and guide the two sides of the coupler.

[0023] It should be explained that, in use, the coupler alignment device is installed on both sides of the coupler, and the coupler is supported and aligned by the first alignment component 1 and the second alignment component 2, so that the coupler is parallel to the vehicle body axis, thereby improving the vehicle coupling efficiency; at the same time, it reduces the wear on the coupler during coupling and increases the service life of the coupler.

[0024] Furthermore, both the first centering component 1 and the second centering component 2 include: an elastic support member, one end of which is provided with the wear block 4 and the connector 3, and the other end of which is provided with a fixing seat 5; the fixing seat 5 is connected to the vehicle body by bolts 6, and the fixing seat 5 is fixedly connected to the vehicle body, so that the wear block 4 provides elastic support to the coupler under the elastic force of the elastic support member.

[0025] Furthermore, the elastic support includes: a pressure rod 7, with a limiting ring plate 8 provided on one end of the pressure rod 7 near the wear block 4 and the connector 3, the other end of the pressure rod 7 being slidably fitted with the fixing seat 5, and a spring 10 being fitted on the pressure rod 7, the spring 10 being elastically supported between the limiting ring plate 8 and the fixing seat 5.

[0026] Furthermore, the end of the pressure rod 7 near the fixed base 5 is a screw structure, and an adjusting nut 9 is screwed onto the screw. The adjusting nut 9 is located on the side of the fixed base 5 away from the spring 10 and is used to adjust the compression of the spring 10.

[0027] It should be explained that when coupling vehicles, the spring 10 is first pre-compressed by adjusting nut 9, so that the wear block 4 is pressed against the side of the coupler under the action of spring 10, and the coupler is in the center position. When the coupler shakes during the coupling process, it will push the wear block 4 to compress the spring 10. At this time, the wear block 4, the connecting piece 3 and the pressure rod 7 will all rotate. After the shaking ends, the coupler will automatically return to the center position under the action of spring 10, ensuring the coupling accuracy and efficiency of the coupler.

[0028] Furthermore, the wear block 4 is made of nylon material.

[0029] It should be explained that the hardness of the wear block 4 is less than that of the coupler. When the wear block 4 wears after a period of use, the wear block 4 can be kept in close contact with the coupler by reducing the pre-tightening amount of the adjusting nut 9, thereby improving the service life of the wear block 4.

[0030] Preferably, the wear block 4 is a detachable structure, which facilitates the replacement of a new wear block 4.

[0031] Furthermore, the connector 3 is an arc-shaped plate structure.

[0032] Furthermore, the connector 3 is provided with two limiting posts (not shown in the figure), which are located on both sides of the rotation direction of the wear block 4, and are used to limit the rotation of the wear block 4 to a certain extent so that it can always contact the side of the coupler.

[0033] In practice, the coupler centering device is installed on both sides of the coupler. The spring is pre-compressed by adjusting the nut, so that the wear block is pressed against the side of the coupler under the action of the spring, so that the coupler is in the center position, improving the vehicle coupling efficiency and reducing wear on the coupler. When the wear block wears, the pre-compression of the adjusting nut can be reduced to keep the wear block pressed against the coupler, thus improving the service life of the wear block.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
