Technical Field

[0001] The utility model is applicable to the technical field of hook buffer repair and provides a line splitting mechanism for a buffer repair line. Background Art

[0002] A hook buffer is a component used to transmit traction and braking force between vehicles and to alleviate longitudinal impact force. It generally includes a coupler, a buffer, a hook tail frame and a follower plate. Due to the complex working scene of the hook buffer and the long-term impact between vehicles, for the sake of safety, the hook buffer device needs to be regularly inspected and maintained, including performance testing of major components and replacement of wearing parts and wear parts. The inspection and maintenance of the buffer is mostly carried out on the transportation line, and maintenance stations are set up on both sides of the transportation line to realize the assembly-line maintenance of the buffer. However, different types of buffer workpieces require different equipment at some maintenance stations. Therefore, usually, one maintenance line can only correspond to the inspection and maintenance of one type of buffer workpiece, and its versatility and utilization rate are low. Utility Model Content

Workpieces that meet the requirements of the first buffer maintenance line continue to be conveyed on the first buffer maintenance line for a subsequent maintenance process, while workpieces that meet the requirements of the second buffer maintenance line are pushed onto the line changing chassis under the action of the line changing pushing unit, and then pushed to the second buffer maintenance line under the action of the bottom stepping pushing unit for a subsequent maintenance process.

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] For example, see the attached Figure 1 The utility model provides a branching mechanism for a buffer repair line, wherein the buffer repair line comprises a first buffer repair line 5 and a second buffer repair line 6. Figure 2 As shown, the line splitting mechanism for the buffer maintenance line is arranged between the first buffer maintenance line 5 and the second buffer maintenance line 6, and includes a line changing chassis 1, a line changing material pushing unit 2, a bottom stepping pushing unit 3 and a workpiece length detection unit 4;

[0022] Among them, the line-changing chassis 1 is used to connect the first buffer maintenance line 5 and the second buffer maintenance line 6. Two workpiece sliding rails 11 are arranged at the bottom of the line-changing chassis 1. The upper end surface of the workpiece sliding rail 11 is arc-shaped. The workpiece is supported by the two workpiece sliding rails 11 on the line-changing chassis 1. The upper end surface of the workpiece sliding rail 11 is designed to be arc-shaped to reduce the resistance of the workpiece when sliding as much as possible, reduce energy loss, and is not easy to damage the surface of the workpiece. The workpiece length detection unit 4 is fixedly arranged on the side wall of the first buffer maintenance line 5. At the same time, the workpiece length detection unit 4 is arranged facing the line-changing chassis 1. The workpiece length detection unit 4 includes two distance sensors arranged at intervals. The distance sensor can sense the workpiece on the first buffer maintenance line 5. When the workpiece passes through the first distance sensor, it is triggered once, and when it passes through the second distance sensor, it is triggered twice. At this time, it is only necessary to reasonably control the distance between the two distance sensors. In this way, since different types of workpieces have different lengths, when the workpiece passes through the second distance sensor, the longer workpiece is still within the sensing range of the first distance sensor. At this time, it is sensed by the two distance sensors at the same time, while the shorter workpiece can only be sensed by the second distance sensor. Using this principle, different types of workpieces on the first buffer maintenance line 5 can be easily distinguished. Refer to the attached figure. Figure 3The line-changing pushing unit 2 is arranged above the line-changing chassis 1, and includes a pushing unit base 21. The pushing unit base 21 is fixedly provided with a pushing linear drive device 22. The pushing linear drive device 22 is a linear drive oil cylinder. The linear drive oil cylinder is selected because the hydraulic drive is more stable, more suitable for large-mass products such as buffer workpieces, and less prone to failure. The moving end of the pushing linear drive device 22 is fixedly connected with a workpiece pushing plate 23. The side of the first buffer maintenance line 5 is provided with an opening at the position of the line-changing chassis 1. By driving the workpiece pushing plate 23, the workpiece can be pulled from the first buffer maintenance line 5 to the line-changing chassis 1, and the bottom stepping pushing unit 3 is used to stepwise transport the buffer workpiece on the line-changing chassis 1 to the second buffer maintenance line 6. Refer to the attached Figure 4 The bottom stepping push unit 3 includes two stepping push rods 31 and a stepping drive device 32. The stepping push rod 31 is slidably connected to the line-changing chassis 1, and the stepping drive device 32 is fixedly connected to the line-changing chassis 1. The stepping drive device 32 is a linear drive cylinder, and the stepping drive device 32 is drivingly connected to the stepping push rod 31. A plurality of workpiece pushing claws 33 are rotatably provided on the stepping push rod 31. When the bottom stepping push unit 3 pushes the workpiece toward the second buffer maintenance line 6, the workpiece pushing claws 33 abut against the side wall of the workpiece, and under the drive of the stepping drive device 32, the workpiece is pushed toward the second buffer maintenance line 6 until the workpiece reaches the second buffer maintenance line 6;

[0023] In some of the embodiments, the push unit base 21 is slidably connected to a push plate guide rod 24, one end of which is fixedly connected to the workpiece push plate 23. The push plate guide rod 24 mainly functions to improve the stability of the operation of the push linear drive device 22 and to avoid problems such as movement and deformation of the telescopic part of the push linear drive device 22 after long-term reciprocating motion.

[0024] The working principle of this embodiment is as follows:

[0025] Two different types of workpieces are placed on the first buffer maintenance line 5 for transportation. When the workpieces pass through the workpiece length detection unit 4, due to the different lengths of workpieces of different types, when the workpieces pass through the second distance sensor, the longer workpiece is still within the sensing range of the first distance sensor. At this time, it is sensed by both distance sensors at the same time, while the shorter workpiece can only be sensed by the second distance sensor. In this way, the two different types of workpieces can be distinguished. At this time, the workpieces that meet the subsequent maintenance procedures of the first buffer maintenance line 5 continue to be transported on the first buffer maintenance line 5 to complete the maintenance, while the workpieces that meet the subsequent maintenance procedures of the second buffer maintenance line 6 are pulled to the line changing chassis 1 through the workpiece pushing plate 23 under the action of the line changing pushing unit 2, and then the workpieces are pushed to the second buffer maintenance line 6 through the bottom stepping pushing unit 3 for subsequent maintenance. At the same time, the line changing mechanism can also be set up in multiple between the first buffer maintenance line 5 and the second buffer maintenance line 6, so that only one maintenance station is needed for some common models of two workpieces, and the workpieces are transported back and forth through the line changing mechanism to achieve the effect of reducing costs.
