Abstract
Description
Technical Field
[0001] This utility model belongs to the field of internal grinding mill technology, specifically relating to an internal grinding mill traveling device and an internal grinding mill system. Background Technology
[0002] An internal grinding mill, also known as an internal bore grinding mill, is a mechanical device specifically designed for machining and polishing internal holes. The internal grinding mill's traveling frame is a crucial component of the system; it primarily drives the internal grinding rod to rotate and grind, and controls the feed rate of the grinding rod within the internal bore. The motor is fixed to the traveling frame, and the internal grinding rod is mounted at its output end. The grinding wheel is installed at the grinding end of the rod, resting against the internal bore. The feed rate of the grinding rod within the bore is controlled by the forward and backward movement of the frame. When the motor starts, it drives the grinding wheel to rotate at high speed within the workpiece, thus achieving the machining and polishing of the internal bore surface.
[0003] During the machining of the existing internal grinding mill's traveling frame, the grinding end of the internal grinding rod vibrates due to the relatively rough inner hole surface, resulting in significant impact between the internal grinding rod and the traveling frame body, causing the internal grinding rod to be prone to frequent damage. Utility Model Content
[0004] This utility model provides an internal grinding mill traveling device and an internal grinding mill system, which aims to alleviate the impact between the internal grinding rod and the traveling device and avoid damage to the internal grinding rod.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a traveling device for an internal grinding mill, comprising:
[0006] The walking frame has a walking wheel assembly that cooperates with the track at the bottom and a first assembly part at the top surface;
[0007] The internal grinding mill assembly base has a second assembly part at the bottom that is hinged to the first assembly part, and a third assembly part at the top for positioning the internal grinding mill assembly.
[0008] The first assembly part and the second assembly part are connected by a hinge rod. The axis of the hinge rod is perpendicular to the inner grinding rod in the inner grinding mill assembly. The inner grinding mill assembly seat is limited by the hinge rod and the inner grinding pipe, and vibrates at the same frequency as the inner grinding rod, thus providing vibration buffer for the inner grinding mill assembly.
[0009] In this embodiment, an inner grinding mill assembly seat that vibrates with the inner grinding rod is movably mounted on the walking frame to mitigate the impact of the inner grinding rod's jumping on the walking device, reduce damage to the inner grinding rod, and improve the service life of the inner grinding rod.
[0010] In one possible implementation, the walking frame includes a base plate and a frame disposed on the base plate;
[0011] A walking motor for driving the walking wheels is provided on the base plate of the walking frame. The walking motor is detachably mounted on the base plate and disposed outside the frame. The output end of the walking motor is connected to the walking wheel assembly for transmission and is suitable for driving the internal mill walking device to move on a preset track.
[0012] In this embodiment, the walking motor is detachably mounted on the outside of the frame, which facilitates maintenance and replacement and reduces the difficulty of repair.
[0013] In one possible implementation, the wheel assembly is disposed below the frame and includes a bearing seat disposed below the frame, a wheel axle mounted on the bearing seat, and wheels mounted at both ends of the wheel axle.
[0014] The walking motor is connected to the wheel axle via a transmission sprocket.
[0015] In one possible implementation, the first assembly part is a first connecting plate disposed on the upper end face of the walking frame, and the second assembly part is a second connecting plate disposed below the internal grinding mill assembly seat, wherein the first connecting plate and the second connecting plate are connected by the hinge rod.

In another possible implementation, the corresponding first connecting plate and the second connecting plate are arranged in a cross pattern.
[0017] In one possible implementation, a lubricating copper sleeve is provided between the first assembly part and the second assembly part and the hinge rod.
[0018] In one possible implementation,
[0019] The third assembly includes an internal grinding motor mounting part and an internal grinding rod limiting seat disposed on the internal grinding mill assembly base;
[0020] The internal grinding motor is threadedly mounted to the internal grinding motor mounting part via a mounting seat. The internal grinding rod limiting seat is provided with a limiting groove that matches the internal grinding rod, as well as a matching limiting clip.
[0021] In this embodiment, the inner grinding rod is fixed by a limiting seat and a limiting clip to ensure that the inner grinding rod is firmly connected to the inner grinding machine assembly seat, thereby avoiding excessive shaking of the inner grinding rod and improving its stability.

[0038] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0039] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.
[0040] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.
[0041] Furthermore, 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. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0042] In existing technologies, the internal grinding rod and the traveling device are rigidly connected. The vibration generated at the grinding end of the internal grinding rod is transmitted to the fixed end, causing significant impact on both the internal grinding rod and the traveling device. This leads to frequent damage to the internal grinding rod and affects the service life of the internal grinding mill. To address these technical problems, this invention provides an internal grinding mill traveling device and internal grinding mill system. A movable internal grinding mill component assembly seat is added to the traveling frame. During the internal grinding mill's operation, the assembly seat vibrates with the internal grinding rod, changing the traditional rigid assembly to a rotating assembly. This buffers the impact of the internal grinding rod's vibration on the internal grinding rod and the traveling device body, preventing damage to the internal grinding rod and extending the service life of the internal grinding mill. The following detailed description is based on specific embodiments and accompanying drawings.
[0043] Please also refer to Figures 1 to 6The following describes the internal grinding mill traveling device provided by this utility model. The internal grinding mill traveling device includes a traveling frame 40 and an internal grinding mill component assembly base 30. The internal grinding mill assembly base and the traveling frame 40 are rotatably assembled and can jump synchronously with the internal grinding rod to alleviate the impact on the internal grinding rod and the traveling device. Specifically, the traveling frame 40 has a traveling wheel assembly that cooperates with the track 80 at its bottom and a first assembly part 62 on its upper surface. The internal grinding mill component assembly base 30 has a second assembly part 61 at its bottom that is hinged to the first assembly part 62, and a third assembly part 31 at its upper part for positioning the internal grinding mill component 10. The first assembly part 62 and the second assembly part 61 are connected by a hinge rod, the axis of which is perpendicular to the internal grinding rod in the internal grinding mill component 10. The internal grinding mill component assembly base 30 forms a limiting position by means of the hinge rod and the internal grinding mill's tubing, and vibrates at the same frequency as the internal grinding rod, thus providing vibration buffering for the internal grinding mill component 10.
[0044] Compared to existing technologies where the inner grinding rod is directly mounted on the traveling device, the impact generated by the inner grinding rod during grinding is transmitted to the main body of the traveling device, which can easily create weak points at the rigid assembly location and damage the fixed end of the inner grinding rod. In this embodiment, an inner grinding rod assembly seat is added to the traveling frame 40. The inner grinding rod assembly seat is movably connected to the traveling frame 40 and can vibrate synchronously with the inner grinding rod, thereby buffering the impact of the inner grinding rod jumping on the traveling device, avoiding damage to the inner grinding rod, and extending the service life of the inner grinding machine.
[0045] In some embodiments, an externally mounted, detachable walking motor 71 is installed on the walking frame 40 to drive the walking device to move. The external mounting method facilitates maintenance and replacement. For its specific structure, please refer to the figure. Figure 3 The traveling frame 40 includes a base plate 42 and a frame 41 mounted on the base plate 42. A traveling motor 71 for driving the traveling wheels 51 is mounted on the base plate 42 of the traveling frame 40. The traveling motor 71 is detachably mounted on the base plate 42 and disposed outside the frame 41. The output end of the traveling motor 71 is connected to the traveling wheel assembly for transmission and is adapted to drive the internal mill traveling device to move on a preset track 80.
[0046] In this embodiment, the walking motor 71 is externally mounted on the outside of the frame 41 of the walking frame 40, which facilitates repair and replacement after the motor fails, and reduces the maintenance difficulty of the walking device.
[0047] Furthermore, this embodiment provides a transmission method between the walking motor 71 and the walking wheel 51: Please refer to [link to relevant documentation]. Figure 3The traveling wheel assembly is located below the frame 41, and includes a bearing seat 52 located below the frame 41, a wheel axle 53 mounted on the bearing seat 52, and traveling wheels 51 mounted at both ends of the wheel axle 53. The traveling motor 71 is connected to the wheel axle 53 via a transmission sprocket 72.
[0048] In some embodiments, a specific structure of the first assembly portion 62 and the second assembly portion 61 is provided: see [link / reference] Figure 2 The first assembly part 62 is a first connecting plate disposed on the upper end face of the walking frame 40, and the second assembly part 61 is a second connecting plate disposed below the internal grinding mill assembly seat 30. The first connecting plate and the second connecting plate are connected by a hinge rod.
[0049] In some embodiments, two sets of first connecting plates and second connecting plates are arranged side by side and are respectively disposed on the upper end face of the walking frame 40.
[0050] In some embodiments, the corresponding first connecting plate and second connecting plate are arranged in a cross pattern.
[0051] In some embodiments, a lubricating copper sleeve is provided between the first assembly portion 62 and the second assembly portion 61 and the hinge rod to reduce wear.
[0052] In some embodiments, the inner grinding rod is securely fixed on the inner grinding mill assembly base 30 by the limiting seat 22 and the limiting clip 21 to prevent the inner grinding rod from jumping relative to the inner grinding mill assembly base 30. For details, please refer to... Figure 1 , Figure 4-Figure 6 The third assembly part 31 includes an internal grinding motor mounting part and an internal grinding rod limiting seat 22 disposed on the internal grinding mill assembly base 30. The internal grinding motor is threadedly mounted to the internal grinding motor mounting part via the mounting seat, and the internal grinding rod limiting seat 22 is provided with a limiting groove matching the internal grinding rod and a matching limiting clip 21.
[0053] In this embodiment, the fixed end of the inner grinding rod is firmly fixed to the inner grinding machine assembly base 30 by the limiting seat 22 and the limiting clip 21, which effectively reduces the offset between the inner grinding rod and the connecting seat, improves the stability of the inner grinding rod, and thus improves the grinding accuracy of the inner grinding rod.
[0054] This utility model provides an internal grinding mill system, including the internal grinding mill traveling device described in the above embodiments.
[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
