Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for brake hose installation, and in particular to a device for marking the end dimensions of brake hoses in high-speed trains. Background Technology

[0002] In the manufacturing and maintenance of high-speed trains, brake hoses are critical safety components. The dimensional information of the brake hose ends is crucial for many aspects, including correct installation, matching, and quality control. Traditional dimensional marking primarily relies on manual methods. This method has many problems, such as low efficiency, which can severely impact production schedules during large-scale production of high-speed train brake hoses. Furthermore, manual operation is prone to errors, making it difficult to guarantee the clarity and accuracy of the markings; dimensions or markings may be blurry or misaligned. These inaccurate markings can cause problems for subsequent installation workers, as they need to spend extra time identifying the correct dimensions, and may even lead to incorrect brake hose installation due to marking errors, thus creating safety hazards. With the development of high-speed train technology and the continuous improvement of product quality requirements, there are stricter requirements for the standardization and normalization of brake hose end dimensional markings. Traditional marking methods cannot meet these standardized production needs; for example, they cannot guarantee that the style and depth of each marking fully comply with standard specifications.

[0003] Furthermore, the existing operating method involves the following: In environments with densely packed pneumatic system piping within the vehicle, there are various types of quick-connect fittings. Fittings of the same model must be connected to quick-connect fittings of the same diameter. The installation angle of the fitting is adjusted by one hand, and the fitting is measured and cut at the base of the quick-connect fitting. A measuring tape is used, starting from the end of the fitting, to measure the insertion depth. A crosshair, approximately 10mm long, is then marked with a green marker before inserting the fitting. This method requires on-site measurement of the insertion depth for different models and diameters of quick-connect fittings. Space constraints at some installation points can restrict operation, leading to inaccuracies in measurement and inconsistent marking thickness. This installation method is both time-consuming and labor-intensive. Inconsistent insertion depths even for the same model of brake hose can prevent the operator from accurately determining whether the fitting is installed correctly, creating potential quality issues.

[0004] Therefore, based on the above problems, it is necessary for this utility model to provide a device for marking the end dimensions of the brake hose of a high-speed train that can replace manual dimension marking. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the existing technology and provide a device for marking the size of the end of the brake hose of a high-speed train.

[0015] Furthermore, the switching mechanism includes a base that engages with a groove in a trapezoidal structure at the bottom of the device frame. A sleeve is formed on the upper part of the base to open the marking window, and a channel through which the brake hose can pass is formed inside the sleeve.

[0016] Furthermore, the pressure arm has an irregular shape, with a shaft hole in the middle.

[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0038] See Figure 1 As shown;

[0039] A utility model discloses a device for marking the end size of brake hoses in high-speed trains, comprising: a device frame 1, a switching mechanism 2, a pressure arm mechanism 3, and a marking mechanism 4.

[0040] A pin 101 is fixedly connected inside the device frame 1;

[0041] The switching mechanism 2 is installed inside the device frame 1 and is used to insert the brake hose 6 perpendicular to the axis of the pin 101. The switching mechanism 2 has a marking window 204 that exposes the outer wall of the brake hose 6.

[0042] The pressure arm mechanism 3 has a pressure arm 301 rotatably connected to the pin 101. One end of the pressure arm 301 has a first free end A for rotatably connecting to the marking mechanism 4 with a mark 402. The other end of the pressure arm 301 has a second free end B extending toward the end of the switching mechanism 2 so that the brake hose 6 abuts against the second free end B, driving the pressure arm 301 to rotate and causing the marking mechanism 4 to move downward and mark the outer wall of the brake hose 6 with a mark 403 through the marking window 204. Thus, this device can replace manual marking of the brake hose 6 with a mark 402 403, eliminate marking errors caused by human factors, and improve the stability of the marking 402 limit application.

[0043] See Figure 2 As shown:

[0044] Preferably, the marking device further includes an elastic reset member 5 for driving the pressure arm 301 to reset. One end of the elastic reset member 5 is connected to the pressure arm 301, and the other end is connected to the inside of the device frame 1. Specifically, a hanging ring is fixed to the upper part of the outer wall of the first free end A of the pressure arm 301, and a hanging ring is fixed to the side wall of the device frame 1. The elastic reset member 5 is a tension spring. One end of the tension spring is connected to the hanging ring on the pressure arm 301, and the other end is connected to the hanging ring on the device frame 1. The tension spring contracts to drive the pressure arm 301 to rotate counterclockwise around the pin 101 to reset. Of course, the elastic reset member 5 can also be a compression spring. The compression spring can be set in the device frame 1 at the second free end B of the pressure arm 301. One end of the compression spring abuts against the side wall of the device frame 1, and the other end abuts against the outer wall of the second free end B of the pressure arm 301. The compression spring extends to drive the pressure arm 301 to rotate, which can also drive the pressure arm 301 to rotate counterclockwise around the pin 101 to reset.

[0045] See Figure 6 As shown:

[0046] Preferably, the marking mechanism 4 includes a base 401. The top end of the base 401 is rotatably connected to the pressure arm 301 via a shaft 404. The pressure arm 301 has a groove, and the shaft 404 passes through the groove and is connected to the pressure arm 301. Fixing clips are installed at both ends of the pin 101 and the shaft 404 to prevent the pin 101 and the shaft 404 from falling off. A mark 402 with ink is installed at the bottom end of the base 401. A cross-shaped mark 403 is provided on the marking surface formed at the bottom of the mark 402. The mark 402 has ink. When in use, the pressure arm 301 rotates clockwise and drives the mark 402 to move downward through the base 401. The mark 402 contacts the outer surface of the brake hose 6 through the marking window 204, thereby imprinting the mark 403 on the surface of the brake hose 6.

[0047] Preferably, the marking mechanism 4 further includes an adjusting rod 405. The base 401 has a marking 402 installed in the lower part through a receiving cavity. The marking 402 can be displaced relative to the base 401 along the axis of the brake hose 6 within the receiving cavity. The adjusting rod 405 passes through the receiving cavity and is rotatably connected to the base 401. The adjusting rod 405 and the marking 402 are screw-driven. Specifically, the adjusting rod 405 is a bolt rod. In use, the adjusting rod 405 is driven to move the marking 402 along the axis of the brake hose 6, thereby adjusting the position of the marking 402 so that the marking 402 mark 403 formed on the brake hose 6 meets the technical requirements.

[0048] See Figure 5 As shown:

[0049] Preferably, the switching mechanism 2 includes a base 201, which engages with a trapezoidal slide groove 102 at the bottom of the device frame 1. Specifically, the base 201 is a trapezoidal slider that cooperates with the slide groove 102. The base 201 has a sleeve 203 with a marking window 204 formed on its upper part. The sleeve 203 has a channel 205 through which the brake hose 6 can pass. In use, the brake hose 6 contacts the second free end B of the pressure arm 301 through the channel 205, thereby driving the pressure arm 301 to rotate clockwise and causing the marking mechanism 4 to move downward, thus completing the marking 402 action.

[0050] See Figure 4 As shown:

[0051] Preferably, the pressure arm 301 has an irregular shape. The pressure arm 301 has a shaft 404 hole 302 in the middle. The pressure arm 301 has a first arm extending downward on one side of the shaft hole 302, forming a first free end A. The pressure arm 301 has a second arm extending downward at an incline on the other side of the shaft 404 hole 302. The end of the second arm is connected to a third arm extending downward, forming a second free end B. The third arm can cover the channel 205 of the sleeve 203 so that the brake hose 6 abuts against the pressure arm 301.

[0052] See Figure 3 As shown:

[0053] Preferably, one end of the device frame 1 is provided with an insertion port 104, and the switching mechanism 2 is installed into the device frame 1 through the insertion port 104. The insertion port 104 facilitates the replacement of different models of the switching mechanism 2, thereby adapting to different specifications of brake hoses 6. One side of the device frame 1 is provided with an inspection port, and the inspection port is covered by an inspection door 103. The inspection door 103 is fixedly connected to the device frame 1 by screws.

[0054] In the above technical solution, this utility model provides a device for marking the end size of a high-speed train brake hose, and its method of use is as follows:

[0055] First, prepare the corresponding switching mechanism 2 according to the diameter of the brake hose to be marked. Before marking the brake hose, first take a brake hose 6 for a marking test. If the marking size meets the technical requirements, it can continue to be used. If it does not meet the requirements, use a wrench to adjust the adjusting rod 405. By driving the adjusting rod 405, adjust the marking 402 back and forth along the axis of the brake hose 6 until it meets the technical requirements until it is qualified. Then, hold one end of the brake hose 6 and insert it into the channel 205 of the switching mechanism 4, and apply force to make the brake hose... The first end of the 6 abuts against the side of the second free end B of the pressure arm 301, driving the pressure arm 301 to rotate clockwise around the pin 101. At this time, the pressure arm 301, with the pin 101 as the fulcrum, will drive the marking mechanism 4 to apply pressure to the outer wall of the brake hose 6 through the marking 402. The ink in the marking 402 adheres to the surface of the brake hose 6 through the mark 403 to mark the size of the brake hose. When the brake hose 6 is pulled outward, the pressure arm mechanism 3 rotates counterclockwise under the action of the elastic reset member 5, driving the marking mechanism 4 to reset and completing the marking operation.

[0056] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
