Description

Technical Field

[0001] This utility model relates to the field of carbon brush production technology, and in particular to a carbon brush oiling fixture. Background Technology

[0002] Carbon brushes are crucial components in automobiles and other equipment, and their performance directly impacts equipment operation. During the manufacturing process, the milled surfaces of carbon brushes undergo an oiling process to reduce friction and wear, thereby improving the brush's performance and lifespan.

[0003] However, existing oiling fixtures have certain limitations. Although they can perform basic oiling operations for conventional carbon brushes, they are difficult to achieve the ideal continuous and uniform effect in terms of oil film coverage. This results in some areas of the carbon brush having excessively thick oil film, increasing unnecessary costs, while other areas have oil films that are too thin and fail to meet performance requirements. They also have poor adaptability to carbon brushes of different sizes and curvatures. Most existing fixtures lack flexible and precise adjustment mechanisms. When faced with diverse carbon brush products, it is difficult to quickly and accurately adjust the oiling position and method, leading to problems such as missed coating and uneven coating. This greatly limits the compatibility of the process and fails to meet the market's diverse needs for carbon brush products. Summary of the Invention

[0004] To address the above problems, this application provides a carbon brush oiling fixture, which includes a support base, a horizontal moving unit on the support base, a vertical moving unit on the horizontal moving unit, and an oiling unit on the vertical moving unit. The oiling unit includes an oil pipe fixedly mounted on the vertical moving unit, the oil pipe being connected to an oil injection valve, an oiling brush located below the oil injection valve, and an oiling position adjustment unit on the vertical moving unit. The oiling unit is mounted on the oiling position adjustment unit.

[0005] In one embodiment, the oiling position adjustment unit includes a position adjustment support plate fixedly mounted on the vertical moving unit. An adjustment screw is provided on the position adjustment support plate. One end of the adjustment screw is connected to a hand crank, and the other end is connected to the oiling support plate via a thread. The oil injection valve is installed on the oiling support.

[0006] In one embodiment, the oil injection valve is mounted on the oiling support plate by a bolt assembly.

[0007] In one embodiment, the horizontal moving unit includes a horizontal slide rail fixedly mounted on the support base, a horizontal slider is provided on the horizontal slide rail, a horizontal support plate is provided on the horizontal slider, and the horizontal support plate is connected to a horizontal driver mounted on the support base.

[0026] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0027] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0028] like Figure 1-3 As shown, a carbon brush oiling fixture is provided with a support base 1, a horizontal moving unit 2 on the support base 1, a vertical moving unit 3 on the horizontal moving unit 2, and an oiling unit 4 on the vertical moving unit 3. The oiling unit 4 includes an oil pipe 41 fixedly installed on the vertical moving unit 3, the oil pipe 41 being connected to an oil injection valve 42, and an oiling brush 43 being provided below the oil injection valve 42. The fixture is characterized in that an oiling position adjustment unit 5 is provided on the vertical moving unit 3, and the oiling unit 4 is disposed on the oiling position adjustment unit 5.

[0029] Specifically, the support base 1 is the basic support component of the entire fixture. The horizontal moving unit 2 is installed on the support base 1 and is responsible for moving horizontally to deliver the oiling unit 4 to the carbon brush milling arc surface station. The vertical moving unit 3 is fixed on the horizontal moving unit 2 and drives the oiling unit 4 to move vertically, controlling the lifting height of the oiling brush 43. The oiling position adjustment unit 5 is set on the vertical moving unit 3 and is used to fine-tune the position of the oiling unit 4 to adapt to carbon brushes of different sizes or curvatures and different models, avoiding missed or excessive coating due to dimensional deviations. During the oiling process, the horizontal moving unit 2 first drives the vertical moving unit 3 and the oiling unit 4 on it to move forward to the designated position. Then, the vertical moving unit 3 starts, driving the oiling position adjustment unit 5 and the oiling brush 43 to move upward. During the upward movement, the oiling brush 43 performs the oiling operation through the oil injection valve 42, completing the lifting and oiling process from bottom to top. Once the oiling brush 43 rises to the predetermined position, the horizontal moving unit 2 restarts, driving the vertical moving unit 3 to move backward. Then, the vertical moving unit 3 drives the oiling brush 43 downward, resetting it to its initial position. Thus, the entire oiling process is successfully completed. In this application, by setting up the linkage control between the horizontal moving unit 2 and the vertical moving unit 3, it is ensured that the oiling brush 43 can be accurately positioned at the starting point of the carbon brush milling arc surface, and through a uniform upward pulling motion, continuous and uniform oil film coverage is achieved. The synchronous adjustment of the oil injection valve 42 and the lifting speed can precisely control the oil quantity and thickness, avoiding the problem of excessively thick or thin oil films in traditional manual operations. By integrating the oiling position adjustment unit 5 onto the vertical moving unit 3, lateral offset is supported, adapting to carbon brushes of different sizes and curvatures, avoiding missed coatings or uneven coating due to workpiece tolerances, and significantly improving process compatibility.

[0030] like Figure 1 , 3 As shown in Figure 5, the oiling position adjustment unit 5 includes a position adjustment support plate 51 fixedly mounted on the vertical moving unit 3. An adjustment screw 52 is provided on the position adjustment support plate 51. One end of the adjustment screw 52 is connected to a hand crank 53, and the other end is connected to the oiling support plate 44 by a thread. The oil injection valve 42 is mounted on the oiling support plate 44.

[0031] Specifically, the adjusting screw 52 is fixed to the position adjusting support plate 51 by bearings. When the operator needs to adjust the oiling position, they only need to gently turn the hand crank 53. As the hand crank rotates, the adjusting screw 52 also begins to rotate. Since the oiling support plate 44 and the adjusting screw 52 are connected by threads, when the screw rotates, the oiling support plate 44 will move in the horizontal direction, precisely adjusting the relative position between the oiling brush 43 and the carbon brush milled arc surface, thereby ensuring the accuracy and consistency of the oiling process.

[0032] like Figure 1 As shown, the oil injection valve 42 is mounted on the oiling support plate 44 by a bolt assembly.

[0033] Specifically, the oil injection valve 42 is mounted on the oiling support plate 44 by bolt assembly. This mounting method is not only stable and reliable, but also provides the possibility of adjusting the angle of the oil injection valve 42. By mounting the oil injection valve 42 on the oiling support plate 44 by bolt assembly, and allowing the bolt assembly to be loosened for angle adjustment, it provides operators with great flexibility and convenience.

[0034] like Figure 1 As shown, the horizontal moving unit 2 includes a horizontal slide rail 21 fixedly installed on the support base 1, a horizontal slider is provided on the horizontal slide rail 21, a horizontal support plate 22 is provided on the horizontal slider, and the horizontal support plate 22 is connected to a horizontal driver 23 installed on the support base 1.

[0035] Specifically, the horizontal movement is guided by the horizontal slide rail 21 fixedly installed on the support base 1. The horizontal slider (not shown in the figure) slides on the horizontal slide rail 21 and carries the horizontal support plate 22. The horizontal support plate 22 is connected to the horizontal driver 23 installed on the support base 1. When the driver 23 is started, it pushes the horizontal support plate 22 and its load along the horizontal slide rail 21 to move stably and accurately.

[0036] like Figure 1 , 2 As shown, the vertical moving unit 3 includes a vertical support plate 31 disposed on the horizontal support plate 22, a vertical slide rail 32 disposed on the vertical support plate 31, a vertical slider 33 disposed on the vertical slide rail 32, an oiling support plate 44 disposed on the vertical slider 33, and the vertical slider 33 being connected to a vertical driver 34 mounted on the vertical support plate 31.

[0037] Specifically, a vertical slide rail 32 is installed on a vertical support plate 31 fixed on a horizontal support plate 22. A vertical slider 33 slides on the slide rail and supports an oiling support plate 44. A vertical driver 34 is installed on the vertical support plate 31 and connected to the vertical slider 33. When the driver 34 is started, it drives the vertical slider 33 and the oiling support plate 44 on it to move up and down steadily and precisely along the vertical slide rail 32.

[0038] like Figure 1 , 4 As shown, a hydraulic buffer 11 is provided on the support base 1, and the hydraulic buffer 11 is located at the front end of the horizontal support plate 22 in the direction of movement.

[0039] Specifically, the hydraulic buffer 11 installed on the support base 1 is located at the front end of the moving path of the horizontal support plate 22. When the horizontal support plate 22 moves to the limit position, the hydraulic buffer 11 smoothly and controllably decelerates and stops the horizontal support plate 22, thereby effectively preventing the impact and vibration caused by the collision, protecting the tooling structure and improving the stability of operation.

[0040] like Figure 1 As shown, an oil collection box 5 is provided below the oiling brush 43.

[0041] Specifically, the oil collection box 5 is mainly used to collect and contain excess oil that drips during the oiling process, keeping the work area clean and preventing oil from polluting the surrounding environment or equipment.

[0042] This application discloses a carbon brush oiling fixture, comprising a horizontal moving unit 2, a vertical moving unit 3 mounted on the horizontal moving unit 2, and an oiling unit 4 mounted on the vertical moving unit 3. The oiling unit 4 includes an oil pipe 41, an oil injection valve 42, and an oiling brush 43. An oiling position adjustment unit 5 is mounted on the vertical moving unit 3. The horizontal moving unit 2 is mounted on a support base 1 and is responsible for moving horizontally to deliver the oiling unit 4 to the carbon brush milling arc surface station. The vertical moving unit 3 is fixed to the horizontal moving unit 2 and drives the oiling unit 4 to move vertically, controlling the lifting height of the oiling brush 43. The oiling position adjustment unit 5 is mounted on the vertical moving unit 3 and is used to fine-tune the position of the oiling unit 4 to adapt to carbon brushes of different sizes or curvatures, and to different models of carbon brushes, avoiding missed or excessive coating due to dimensional deviations. In this application, by setting up the linkage control of the horizontal moving unit 2 and the vertical moving unit 3, it is ensured that the oiling brush 43 can be accurately positioned to the starting point of the carbon brush milling arc surface, and the oil film is continuously and evenly covered by the uniform upward pulling action. The synchronous adjustment of the oil injection valve 42 and the lifting speed can accurately control the oil quantity and thickness, avoiding the problem of the oil film being too thick or too thin in traditional manual operation; by setting the oiling position adjustment unit 5 integrated on the vertical moving unit 3, it supports lateral offset, adapts to carbon brushes of different sizes and curvatures, avoids missed coating or uneven coating caused by workpiece tolerances, and significantly improves process compatibility.
