Description

Technical Field

[0001] This utility model belongs to the field of tie rod repair and manufacturing technology, specifically relating to a clamping device for making color ring markings on tie rods. Background Technology

[0002] Repairing and manufacturing control rods is an indispensable part of aircraft overhaul. During installation, the mounting location of the control rod must be identified based on the color-coded rings. The accuracy of these markings ensures correct and efficient installation. Due to the large number of control rods and the inconsistent number of color-coded rings in different locations, current maintenance methods use masking tape to create these markings. The amount of tape used depends on the width and number of color-coded rings. Only after this is done can the control rod be painted with the markings, and then four layers of masking tape are applied. This method is complex, results in uneven color-coded ring widths, and allows the paint to easily seep into non-marked areas of the control rod, leading to inaccurate markings, poor appearance, and unsatisfactory work results. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing methods for making color ring markings on pull rods, such as complex methods and poor marking effects, and to provide a clamping device for making color ring markings on pull rods.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A clamping device for making color ring markings on a pull rod includes a handle, a spring, a pin, a rubber sealing gasket, and a clamping part for clamping the outer wall of the pull rod;

[0006] The handle includes two parallel force-applying components, with a spring between the force-applying components, and the two ends of the spring are respectively engaged with the inner walls of the two force-applying components;

[0007] The force-applying ends of the two force-applying components can approach each other under the action of external force and open the clamping part, and can separate under the action of spring rebound force and close the clamping part to clamp the pull rod;

[0008] The connecting end of the force-applying component is connected by a pin, and the pin passes through the spring;

[0009] The connecting end of the force-applying component is symmetrically provided with multiple retaining rings, which are parallel to each other and constitute the clamping part; the retaining rings at corresponding positions of two force-applying components are joined together to form a retaining ring that can completely cover the outer wall of the pull rod; the gap between adjacent retaining rings is used to spray paint on the clamping device and then spray paint on the outer wall of the pull rod to form a colored ring mark;

[0010] The rubber sealing gasket is fixed to the inner wall of the retaining ring.

[0011] Furthermore, the rubber sealing gasket is a semi-annular structure that matches the retaining ring, and one end of the semi-annular structure is provided with a vertically outwardly extending extension, which is in contact with the open end face of the retaining ring.

[0012] Furthermore, symmetrical connecting lugs are provided on both sides of the connecting end of the two force-applying components to connect the two sides of the connecting end of the two force-applying components; the two ends of the pin are respectively installed on the lugs on both sides of the connecting end of the force-applying components to connect the connecting ends of the two force-applying components.

[0013] Furthermore, the inner walls of the force-applying ends of the two force-applying components are provided with slots, and the two ends of the spring are respectively locked in the slots.

[0014] Furthermore, the gaps between adjacent retaining rings are equal.

[0015] Furthermore, the clamping part and the handle part are integrally machined from metal material.

[0016] Furthermore, the handle and the clamping part are made of T10 material and are hardened to a hardness ≥58HRC.

[0017] The advantages of this utility model are:

[0018] 1. The clamping device of this utility model includes a clamping part for clamping the pull rod body. The clamping part is designed with multiple spaced retaining rings. When in use, the clamping device is clamped on the pull rod. After spraying, a color ring mark is formed at the gap between adjacent retaining rings. The gap between adjacent retaining rings can be determined according to the needs of color ring mark production, ensuring the consistency of the width of the color ring mark. The process of making color rings using this utility model device is simple and efficient. It only takes 10 seconds to make color rings on a single pull rod and only 2.5 hours to make color rings on a single aircraft pull rod using the traditional method. In contrast, it takes 30 seconds to make color rings on a single pull rod and 4 hours to make color rings on a single aircraft pull rod using the traditional method.

[0019] 2. This utility model uses a rubber sealing gasket pasted on the inner wall of the retaining ring to prevent paint from seeping into other areas during spraying, resulting in a high-quality appearance of the color ring markings.

[0020] 3. This utility model has a simple structure and is easy to manufacture. It is not restricted by the site when used and can be used without obstacles in the manufacturing, repair or assembly of the tie rod.

[0021] 4. When using the traditional method to manufacture the control rod color ring, the monthly cost per aircraft is about 10,000 yuan. However, using the device of this utility model to manufacture the control rod color ring only costs about 5,000 yuan per aircraft per month, which greatly reduces the cost of control rod maintenance.

[0026] The embodiments of the present invention are described in detail below. These embodiments are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] To address the problems of low efficiency and poor quality in creating color ring marks on pull rods during repair, this utility model provides a clamping device for creating color ring marks on pull rods. (Refer to...) Figure 1 The clamping device includes a handle portion 1, a clamping portion 2, a spring 3, a pin 4, and a rubber sealing gasket 5. The handle portion 1 includes two parallel first force-applying members 101 and 102. Vertically arranged connecting pieces are located on both sides of the connecting ends of the first force-applying members 101 and 102. The pin 4 is mounted on the connecting pieces at both ends, connecting one end of the first force-applying members 101 and 102. A spring 3 is positioned between the first force-applying members 101 and 102, with both ends of the spring 3 respectively engaged with the inner walls of the two first and second force-applying members, and the spring is sleeved on the pin 4. The other ends of the first force-applying members 101 and 102 are used to bring them closer together under external force to open the clamping portion; and to separate under the restoring force of the spring 4 to close the clamping portion.

[0028] Multiple retaining rings 201 are symmetrically arranged on the outer sides of the first and second force-applying components. The retaining rings on the same force-applying component are parallel to each other. The retaining rings on the first and second force-applying components can be joined to form a retaining ring that wraps around the outer wall of the pull rod. The retaining ring constitutes a clamping part 2 for clamping the pull rod body. The gap between adjacent retaining rings is used to spray paint onto the outer wall of the pull rod after the clamping device is coated to form a color ring mark. Specifically, the gap between adjacent retaining rings is equal, or the gap between adjacent retaining rings can be determined according to the actual width requirement of the color ring mark.

[0029] Specifically, the inner walls of the first force-applying component 101 and the second force-applying component 102, and the ends away from the pin, are provided with slots, and the two ends of the spring 3 are respectively locked in the slots.

[0030] Specifically, the handle and the clamping part are integrally machined to extend the service life of the clamping device. Both the handle and the clamping part are made of a low-rigidity metal material, allowing the clamping part to open or close when the handle is closed or opened. Considering the frequency of use of the clamping device and the material of the pull rod, the handle and the clamping part are made of T10 material, and the heat treatment is quenching, resulting in a punch hardness ≥58HRC after quenching.

[0031] Reference Figure 2 The rubber sealing gasket 5 is adhered and fixed to the inner wall of the retaining ring 201. This serves two purposes: first, to prevent paint leakage onto the rest of the pull rod surface during spraying; and second, to prevent damage to the pull rod surface from the metal retaining ring when directly clamping the pull rod. Adhering the rubber sealing gasket 5 to the inner wall of the retaining ring ensures a good fit between the retaining ring and the pull rod surface, significantly improving the spraying quality of the pull rod's color ring. The rubber sealing gasket 5 is a semi-circular structure that matches the retaining ring 201, and one end of the semi-circular structure has a vertically outward-extending extension. This extension fits snugly against the open end face of the retaining ring, ensuring that paint does not seep from the retaining ring joint into other areas of the pull rod surface.

[0032] Reference Figure 3 When in use, hold the handle of the clamping device of this utility model and press the force-applying ends of the two force-applying parts inward at the same time to open the two locking rings of the clamping part and clamp the locking rings on the pull rod; then spray the gap of the locking rings with colored ring paint to form colored ring marks. The operation process is simple.

[0033] The clamping device of this utility model is simple to process. It only requires designing the diameter of the retaining ring according to the diameter of the pull rod of different models, so that the retaining ring can match and engage with the outer wall of the pull rod.

[0034] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
