DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] This embodiment provides a coupling angle adjustment mechanism, which is installed on an existing coupling detection device and can move on the coupling detection device. The adjustment mechanism includes a test bench, and a guide rail is provided on the test bench. The coupling angle adjustment mechanism of the utility model is as follows: Figure 1-2 As shown, it includes the main structure, cylinder adjustment mechanism, walking mechanism, and handwheel self-locking mechanism. Among them:

[0024] The main structure 1 is the installation foundation of other mechanisms. It is welded by channel steels and ribs of different specifications, and the whole is machined after welding, so that the frame structure has good rigidity, high strength and high installation accuracy. A sensor assembly 3 is installed on each side of the main structure 1. The two sensor assemblies 3 are arranged opposite to each other in the transverse direction. The sensors are equipped to monitor whether the swing angle of the coupler reaches the specified angle.

[0025] The cylinder adjustment mechanism 2 includes four cylinders, namely, a horizontal cylinder 22 installed on the left and right sides of the main structure 1 and a vertical cylinder 21 installed on the upper and lower sides of the main structure 1. Specifically, the four cylinders have the same structure, including a cylinder body and a telescopic rod. The cylinder body is fixedly connected to the main structure 1, one end of the telescopic rod is cooperatively installed in the cylinder body, and the other end extends from the cylinder body and is equipped with a V-shaped claw, wherein the V-shaped opening direction of the claws of the upper and lower cylinders is perpendicular to the V-shaped opening direction of the claws of the left and right cylinders. The telescopic ends of the four cylinders are all arranged inwardly relative to each other. When in use, the coupler product is placed in the middle of the cylinder, and the swing angle of the coupler in the horizontal and vertical directions can be adjusted to achieve all-round angle adjustment of the coupler.

[0026] The traveling mechanism 4 is installed on both sides of the bottom of the main structure 1, and the swing angle adjustment mechanism can move laterally along the guide rail of the coupler detection device through the traveling mechanism 4. Specifically, the traveling mechanism 4 includes four traveling wheels 41 and four hook wheels 42, each traveling wheel 41 and hook wheel 42 form a group, and the hook wheel 42 is located behind the traveling wheel 41. The four groups of traveling wheels 41 and hook wheels 42 are respectively installed at the four corners below the swing angle adjustment mechanism. When in use, the traveling wheel 41 is placed on the guide rail of the coupler detection device, and the hook wheel 42 hooks the test bench under the guide rail. When the swing angle adjustment mechanism is not in the self-locking state, the swing angle adjustment mechanism can be pushed to move laterally. Under the execution of the four traveling wheels and hook wheel groups, the swing angle adjustment mechanism is guaranteed to run smoothly on the track, effectively preventing rollover.

[0027] The hand wheel self-locking mechanism 5 is installed on both sides of the bottom of the main structure 1, and is used to fix the position of the swing angle adjustment mechanism by abutting against the test bench of the coupler detection device. Figure 3-4As shown, the handwheel self-locking mechanism 5 includes a handwheel 53, a threaded push rod 51, a push head 52, and a tightening nut 54. The tightening nut 54 is fixedly installed on the main structure 1. The threaded push rod 51 is threadedly installed in the tightening nut 54. The threaded push rod 51 is horizontally arranged, and the handwheel 53 is installed at one end and the push head 52 is installed at the other end. The handwheel 53 and the threaded push rod 51 are linked. The rotation of the handwheel 53 controls the extension and contraction of the threaded push rod 51 and the tightening nut 54 on the main frame. When the threaded push rods 51 on both sides move toward each other and reach a certain position, the swing angle adjustment mechanism is self-locking. Otherwise, the swing angle adjustment mechanism can move freely. The handwheel self-locking mechanism realizes the self-locking of the swing angle adjustment mechanism at any position, ensuring the safety of the working process.

[0028] When using, Figure 5 As shown, one end of the coupler 8 is fixed on the tooling, and the other end is located in the middle of the horizontal or vertical cylinder of the swing angle adjustment mechanism. The swing angle adjustment mechanism 7 is adjusted by the walking mechanism 4 to move horizontally along the guide rail 9 on the test bench 6, and the swing angle of the coupler 8 in the horizontal and vertical directions is adjusted by the cylinder adjustment mechanism 2, which is convenient for the test personnel to test the swing angle of the coupler. The use of the swing angle adjustment mechanism greatly reduces the adjustment time of the coupler swing angle, avoids the error caused by the operation of the personnel, and lays a good foundation for realizing the detection of the full angle of the coupler and fully reflecting the swing angle performance of the product.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
