Description

Technical Field

[0001] The utility model relates to internal hole machining, and particularly to a steady rest tooling for internal hole machining. Background Art

[0002] The steady rest for internal hole machining is a special tooling fixture, mainly used for the support and positioning of long shafts or tubular parts during internal hole machining. It can accurately fix the parts within the working area of the machine tool, provide stable support for the parts through an adjustable support mechanism, ensure the accuracy and stability during the machining process, thereby effectively reducing part deformation and vibration, and improving the machining quality.

[0003] When the existing steady rests for internal hole machining are in use, they are mostly installed by welding or using fastening screws. Different sizes of parts or different machine tool worktables may require different height settings for the steady rest. If the steady rest cannot adjust its height, it will not be able to adapt to these changes, thus limiting its scope of application. The machining accuracy of parts largely depends on their stability during the machining process. When the height of the steady rest is fixed and not suitable for a specific machining task, it may cause small movements or vibrations of the parts during machining, thereby reducing the machining accuracy. In addition, if the height of the steady rest does not match the machine tool or the parts, additional preparation work (such as using shims or changing the height of the machine tool worktable) may be required to adapt to the height of the steady rest, which will increase the preparation time and reduce the machining efficiency.

[0004] Therefore, a steady rest tooling for internal hole machining is proposed. Content of the Utility Model

[0005] In view of this, the utility model provides a steady rest tooling for internal hole machining to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of the utility model is realized as follows: A steady rest tooling for internal hole machining includes a bottom plate and a steady rest body. A left side of the top of the bottom plate is fixedly connected with an L-shaped plate. An inner side of the L-shaped plate is movably connected with a screw rod through a bearing. A surface of the screw rod is threadedly connected with a screw sleeve. A right side of the screw sleeve is fixedly connected with an adjusting plate. A top of the adjusting plate is fixedly connected with a mounting seat. A mounting groove is formed at a top of the mounting seat. Placement cavities are formed at left and right sides of an inner surface of the mounting seat. A bottom of the steady rest body is fixedly connected with a mounting block, and the mounting block is clamped in an inner cavity of the mounting groove.

[0007] Further preferably, a servo motor for driving the screw rod to rotate is installed at a top of the L-shaped plate, and an output end of the servo motor is fixedly connected to a top of the screw rod.

[0008] Further preferably, a chute is formed on the left side inside the L-shaped plate. The left side of the screw sleeve is fixedly connected with a slider, and the left side of the slider is slidably connected to the inner cavity of the chute.

[0009] Further preferably, guide holes are formed on both the left and right sides of the mounting seat. A guide rod is disposed through the inner cavity of the guide hole, and the inner side of the guide rod extends into the inner cavity of the placement cavity. A return spring is sleeved on the surface of the guide rod, and a limiting block is fixedly connected to the inner side of the guide rod.

[0010] Further preferably, limiting grooves are formed on both the left and right sides of the mounting block, and the inner side of the limiting block is clamped in the inner cavity of the limiting groove.

[0011] Further preferably, a pull plate is fixedly connected to the outer side of the guide rod. Clamping blocks are fixedly connected to both the front side and the back side of the inner side of the pull plate. Clamping grooves are formed on both the left and right sides of the mounting seat and at the front side and the back side of the guide hole. The clamping blocks are clamped in the inner cavities of the clamping grooves.

[0012] Due to the adoption of the above technical solutions in the embodiments of the present utility model, the following advantages are achieved:

[0013] 1. In the present utility model, during the rotation of the screw rod, the screw sleeve is driven to move upward by the action of the thread. The screw sleeve drives the adjusting plate to move upward, and the adjusting plate drives the center frame body to move upward through the mounting seat, so that the use height of the center frame body can be adjusted, ensuring the best relative position between the part and the machine tool, thereby providing more stable support and positioning, reducing vibration and deformation during the machining process, improving machining accuracy and efficiency. This height adjustability also increases the versatility and practicality of the mounting seat, enabling it to be widely applied to various internal hole machining scenarios.

[0014] 2. In the present utility model, by providing the mounting groove and the mounting block, the center frame body can be limited. When the return spring recovers its deformation and extends inward under the influence of the loss of force, it drives the guide rod to move inward. The guide rod drives the limiting block to move inward, so that the inner side of the limiting block is clamped in the limiting groove, which can limit the mounting block, thereby improving the fixing effect on the center frame body. While facilitating the installation of the center frame body, it also facilitates the subsequent disassembly of the center frame body for maintenance or replacement. By providing the clamping block and the clamping groove, the pull plate can be limited, improving the stability of the guide rod during use, and further improving the clamping stability between the limiting block and the limiting groove. By providing the chute and the slider, the stability of the screw sleeve during the up and down movement can be effectively improved.

In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present utility model will be readily apparent by reference to the accompanying drawings and the following detailed description.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0023] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0024] As Figures 1-4As shown in the figure, an embodiment of the present utility model provides a steady rest tooling for internal hole machining, including a bottom plate 1 and a steady rest body 8. On the left side of the top of the bottom plate 1, an L-shaped plate 2 is fixedly connected. Inside the L-shaped plate 2, a screw rod 4 is movably connected through a bearing. A nut sleeve 5 is threadedly connected to the surface of the screw rod 4. On the right side of the nut sleeve 5, an adjusting plate 6 is fixedly connected. On the top of the adjusting plate 6, a mounting seat 7 is fixedly connected. On the top of the mounting seat 7, a mounting groove 12 is provided. On the left and right sides of the inner surface of the mounting seat 7, placing cavities 13 are provided. At the bottom of the steady rest body 8, a mounting block 9 is fixedly connected. The mounting block 9 is clamped in the inner cavity of the mounting groove 12. On the top of the L-shaped plate 2, a servo motor 3 for driving the screw rod 4 to rotate is installed. The output end of the servo motor 3 is fixedly connected to the top of the screw rod 4. On the left side of the inner side of the L-shaped plate 2, a sliding groove 10 is provided. On the left side of the nut sleeve 5, a sliding block 11 is fixedly connected. The left side of the sliding block 11 is slidably connected in the inner cavity of the sliding groove 10.

[0025] In this embodiment, during the rotation of the screw rod 4, the nut sleeve 5 is driven to move upward by the action of the thread. The nut sleeve 5 drives the adjusting plate 6 to move upward. The adjusting plate 6 drives the steady rest body 8 to move upward through the mounting seat 7, so as to adjust the use height of the steady rest body 8, ensure the best relative position between the part and the machine tool, thereby providing more stable support and positioning, reducing vibration and deformation during the machining process, improving machining accuracy and efficiency. This height adjustability also increases the versatility and practicability of the mounting seat 7, making it widely applicable to various internal hole machining scenarios. By setting the sliding groove 10 and the sliding block 11, the stability of the nut sleeve 5 during the up and down movement can be effectively improved.

[0026] In one embodiment, on the left and right sides of the mounting seat 7, guiding holes 14 are provided. A guiding rod 15 is disposed through the inner cavity of the guiding hole 14. The inner side of the guiding rod 15 extends into the inner cavity of the placing cavity 13. A return spring 16 is sleeved on the surface of the guiding rod 15. On the inner side of the guiding rod 15, a limiting block 17 is fixedly connected. On the left and right sides of the mounting block 9, limiting grooves 18 are provided. The inner side of the limiting block 17 is clamped in the inner cavity of the limiting groove 18. On the outer side of the guiding rod 15, a pulling plate 19 is fixedly connected. On the front side and the back side of the inner side of the pulling plate 19, clamping blocks 20 are fixedly connected. On the left and right sides of the mounting seat 7 and on the front side and the back side of the guiding hole 14, clamping grooves 21 are provided. The clamping blocks 20 are clamped in the inner cavity of the clamping grooves 21.

[0027] In this embodiment, by providing the installation groove 12 and the installation block 9, the center rest body 8 can be limited. When the restoring spring 16 loses the influence of force, it restores its deformation and extends inward, driving the guide rod 15 to move inward. The guide rod 15 drives the limit block 17 to move inward, causing the inner side of the limit block 17 to be clamped in the limit groove 18, which can limit the installation block 9, thereby improving the fixing effect on the center rest body 8. It is convenient to install the center rest body 8 and also convenient for subsequent disassembly, maintenance or replacement of the center rest body 8. By providing the clamping block 20 and the clamping groove 21, the pull plate 19 can be limited, improving the stability of the guide rod 15 during use, and further enhancing the clamping stability between the limit block 17 and the limit groove 18.

[0028] When the utility model works: First, pull the pull plate 19 outward. The pull plate 19 drives the guide rod 15 to move outward, and the guide rod 15 drives the restoring spring 16 to deform and be extruded outward. Subsequently, move the center rest body 8 downward so that the installation block 9 is clamped in the inner cavity of the installation groove 12. Release the pull plate 19. At this time, the restoring spring 16 restores its deformation and extends inward due to the loss of the influence of force, driving the guide rod 15 to move inward. The guide rod 15 drives the limit block 17 to move inward, causing the inner side of the limit block 17 to be clamped in the limit groove 18, which can limit the installation block 9, thereby improving the fixing effect on the center rest body 8.

[0029] When it is necessary to adjust the height of the center rest body 8, the output end of the servo motor 3 drives the screw rod 4 to rotate. During the rotation of the screw rod 4, the screw sleeve 5 is driven to move upward by the action of the thread. The screw sleeve 5 drives the adjusting plate 6 to move upward, and the adjusting plate 6 drives the center rest body 8 to move upward through the mounting seat 7, which can adjust the use height of the center rest body 8, ensuring the best relative position between the part and the machine tool, thereby providing more stable support and positioning, reducing vibration and deformation during processing, and improving processing accuracy and efficiency. This height adjustability also increases the versatility and practicality of the mounting seat 7, enabling it to be widely used in various internal hole machining scenarios.

[0030] When it is necessary to disassemble the center rest body 8 for maintenance or replacement, first pull the pull plate 19 outward. The pull plate 19 drives the guide rod 15 to move outward, and the guide rod 15 drives the limit block 17 to move outward, so that the limit block 17 is no longer clamped in the limit groove 18. Then move the center rest body 8 upward so that the installation block 9 is no longer clamped in the inner cavity of the installation groove 12, quickly disassembling the center rest body 8 and effectively saving manpower.

[0031] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described above.
