Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a polishing device for processing metal tubes that is easy to adjust. Background Technology
[0002] In the metal processing industry, polishing of metal tubes is a crucial step. Polishing not only improves the smoothness and aesthetics of the metal tube surface, but also enhances its corrosion resistance and wear resistance, thereby meeting the needs of various industrial applications.
[0003] To meet the polishing requirements at different locations on metal tubes, traditional metal tube polishing machines are usually equipped with polishing position adjustment functions. The polishing wheel is moved and adjusted by a screw or other structure. Although this meets the polishing requirements at different locations on metal tubes to a certain extent, a lot of metal powder is generated during the polishing process. Existing polishing machines generally place the screw or other drive structure directly on the circumference of the polishing wheel, causing metal powder to adhere to the screw or other drive structure, resulting in jamming and reducing the smoothness of the polishing wheel movement adjustment. Therefore, this application proposes a polishing device for metal tube processing that is easy to adjust. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a polishing device for metal tube processing that is easy to adjust, and to solve the technical problem that the adjustment of the polishing device for metal tube processing is not smooth enough due to the influence of metal powder.
[0005] Technical solution
[0006] To solve the above-mentioned technical problems, this utility model provides a polishing device for metal tube processing that is easy to adjust, including a processing table. A clamping component is mounted on one end of the top of the processing table for clamping the metal tube along the length of the processing table. A support arm is provided on one side of the processing table. A polishing component and a vacuum cleaner are mounted on the top of the support arm. A driving mechanism for driving the support arm to move horizontally along the length of the processing table is mounted on the processing table. The driving mechanism includes fixed plates fixed at both ends of the lower surface of the processing table and a screw rotatably mounted between a pair of fixed plates. A first motor for driving the screw to rotate is mounted on one of the fixed plates. The bottom end of the support arm is bent horizontally toward the bottom of the processing table and can be driven to move horizontally by the rotation of the screw.
[0007] Preferably, a movable block is fixedly connected to one end of the support arm that is bent toward the bottom of the processing table, and the movable block is threadedly engaged with the screw.
[0008] Preferably, a sliding rod is fixedly connected between the pair of fixed plates, the sliding rod and the screw are arranged side by side, and the moving block is slidably sleeved with the sliding rod.
[0009] Preferably, a reinforcing plate is fixedly connected at the inner angle of the bending point of the support arm, and the reinforcing plate is configured as a triangular structure.
[0010] Preferably, the clamping component includes a fixed base fixed at one end of the upper surface of the machining table, a three-jaw chuck rotatably mounted on the fixed base facing the center of the machining table, and a second motor mounted on the fixed base for driving the three-jaw chuck to rotate.
[0011] Preferably, the top of the support arm is equipped with a horizontal arm, which is distributed along the width of the processing table. The polishing part includes a fixed frame fixed to the end of the horizontal arm away from the support arm, a grinding wheel rotatably mounted on the fixed frame, and a third motor mounted on the fixed frame for driving the grinding wheel to rotate. The vacuum cleaner is mounted at the bottom of the horizontal arm and the air inlet is distributed facing downwards from the grinding wheel.
[0012] Preferably, an electric push rod is fixed to the top of the support arm away from the cross arm. The electric push rod is distributed along the width direction of the processing table, and the telescopic end of the electric push rod passes through the support arm and connects to the cross arm.
[0013] Preferably, a guide arm is horizontally arranged on the side of the top of the support arm facing the horizontal arm. A pair of guide arms are provided and are respectively located on both sides of the telescopic end of the electric push rod. The horizontal arm and the pair of guide arms are slidably sleeved together.
[0014] Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention utilizes a clamping mechanism and a driving mechanism. A three-jaw chuck clamps and fixes the metal tube, a second motor drives the three-jaw chuck and the metal tube to rotate, an electric push rod pushes the horizontal arm toward the metal tube, and a third motor drives the grinding wheel to rotate at high speed and contact the rotating metal tube, thus polishing the surface of the metal tube. By controlling the distance the electric push rod moves the grinding wheel, the thickness of the polishing on the metal tube can be adjusted. A first motor drives the screw to rotate, and with the threaded engagement between the screw and the moving block and the guiding engagement of the sliding rod, the support arm can drive the horizontal arm and the grinding wheel to move along the length of the processing table, adjusting the polishing position of the metal tube. This design offers high flexibility and can meet the polishing needs of different positions on the metal tube.
[0017] This invention utilizes a vacuum cleaner design. Because the vacuum cleaner is positioned below the horizontal arm with its air inlet facing downwards towards the grinding wheel, during metal polishing, the side of the grinding wheel that polishes the metal tube rotates downwards. As the grinding wheel polishes the metal tube, the resulting metal powder will splash towards the processing table. Activating the vacuum cleaner effectively removes as much of the polishing powder as possible, minimizing its scattering and reducing environmental pollution. Furthermore, since the screw and slide rod used to drive the grinding wheel's translation are located below the processing table, the metal powder generated during polishing does not adhere to the surface of the screw and slide rod, thus preventing it from affecting the normal movement and adjustment of the grinding wheel and ensuring smooth metal tube polishing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This embodiment provides a polishing apparatus for processing metal tubes that is easy to adjust, as shown in the schematic diagram below. Figures 1-4 As shown, the machine includes a processing table 1. A clamping component 2 is mounted on one end of the top of the processing table 1. The clamping component 2 is used to clamp the metal tube along the length of the processing table 1. Specifically, the clamping component 2 includes a fixed seat 13 fixed at one end of the upper surface of the processing table 1, a three-jaw chuck 14 rotatably mounted on the fixed seat 13 facing the middle of the processing table 1, and a second motor 15 mounted on the fixed seat 13 to drive the three-jaw chuck 14 to rotate. The three-jaw chuck 14 can clamp and fix one end of the metal tube, so that the metal tube is distributed along the length of the processing table 1. The second motor 15 is started to drive the three-jaw chuck 14 and the metal tube to rotate, so that the metal tube can be ground and polished in a rotating state.
[0026] Furthermore, a support arm 3 is provided on one side of the processing table 1. A polishing component 5 and a vacuum cleaner 11 are mounted on the top of the support arm 3. A drive mechanism 6 is mounted on the processing table 1 to drive the support arm 3 to translate along the length of the processing table 1. A horizontal arm 4 is mounted on the top of the support arm 3 and is distributed along the width of the processing table 1. The polishing component 5 includes a fixed frame 16 fixed to the end of the horizontal arm 4 away from the support arm 3, a grinding wheel 17 rotatably mounted on the fixed frame 16, and a third motor 18 mounted on the fixed frame 16 to drive the grinding wheel 17 to rotate. The vacuum cleaner 11 is mounted at the bottom of the horizontal arm 4 and its air inlet is distributed facing downwards from the grinding wheel 17. An electric push rod 20 is fixed to the top of the support arm 3 away from the horizontal arm 4 and is distributed along the width of the processing table 1. The telescopic end of the electric push rod 20 passes through the support arm 3 and connects to the horizontal arm 4. Through this structure, the polishing component 5 is mounted on the metal... After the tube is clamped and driven to rotate, the electric push rod 20 pushes the horizontal arm 4 toward the metal tube. The third motor 18 drives the grinding wheel 17 to rotate at high speed and contact the rotating metal tube, thus polishing the surface of the metal tube. By controlling the distance that the electric push rod 20 pushes the grinding wheel 17 to move, the thickness of the grinding wheel 17 on the metal tube can be adjusted to meet the grinding and polishing requirements of the metal tube. Since the vacuum cleaner 11 is distributed below the horizontal arm 4 and the air inlet is distributed downwards towards the grinding wheel 17, during the metal polishing process, the side of the grinding wheel 17 that is polishing the metal tube rotates downwards. During the polishing process, the metal powder generated by the grinding wheel 17 will splash toward the processing table 1. Activating the vacuum cleaner 11 can remove as much of the metal powder generated during polishing as possible, and avoid the metal powder from scattering in all directions, thereby reducing the pollution of the metal powder to the environment.
[0027] In this embodiment, a guide arm 19 is horizontally arranged on the side of the top of the support arm 3 facing the horizontal arm 4. A pair of guide arms 19 are provided and are respectively located on both sides of the telescopic end of the electric push rod 20. The horizontal arm 4 and the pair of guide arms 19 are slidably sleeved together. The sleeved engagement between the guide arms 19 and the horizontal arm 4 can guide the movement of the horizontal arm 4. The pair of guide arms 19 are located on both sides of the telescopic end of the electric push rod 20 and can provide shielding protection for the telescopic end of the electric push rod 20.
[0028] In a further embodiment, the drive mechanism 6 includes fixed plates 7 fixed at both ends of the lower surface of the processing table 1 and a screw 8 rotatably mounted between a pair of fixed plates 7. A first motor 10 for driving the screw 8 to rotate is mounted on one of the fixed plates 7. The bottom end of the support arm 3 is bent horizontally toward the bottom of the processing table 1 and can be driven to translate by the rotation of the screw 8. Specifically, a moving block 12 is fixedly connected to the end of the support arm 3 that is bent toward the bottom of the processing table 1. The moving block 12 is threadedly engaged with the screw 8. A sliding rod 9 is fixedly connected between the pair of fixed plates 7, and the sliding rod 9 is parallel to the screw 8. The arrangement involves a sliding connection between the movable block 12 and the slide rod 9. The first motor 10 drives the screw 8 to rotate. With the threaded engagement between the screw 8 and the movable block 12 and the guiding engagement of the slide rod 9, the support arm 3 can drive the cross arm 4 and the grinding wheel 17 to move along the length of the processing table 1, thereby adjusting the grinding position of the metal tube. Since the screw 8 and the slide rod 9 used to drive the grinding wheel 17 to move are located below the processing table 1, and with the vacuum cleaner 11 removing the metal powder, the phenomenon that the metal powder generated during polishing adheres to the surface of the screw 8 and the slide rod 9 and affects the normal movement and adjustment of the grinding wheel 17 can be avoided.
[0029] In this embodiment, a reinforcing plate 21 is fixedly connected at the inner corner of the bend of the support arm 3. The reinforcing plate 21 is configured as a triangular structure to improve the structural strength of the bend of the support arm 3.
[0030] Working Principle: In use, a three-jaw chuck 14 clamps and fixes one end of the metal tube, distributing the metal tube along the length of the processing table 1. The second motor 15 is started, driving the three-jaw chuck 14 and the metal tube to rotate. Then, the third motor 18 is started, driving the grinding wheel 17 to rotate. The electric push rod 20 is started, pushing the horizontal arm 4 towards the metal tube. When the high-speed rotating grinding wheel 17 contacts the rotating metal tube, the surface of the metal tube is ground and polished. The thickness of the polishing effect can be adjusted by controlling the distance the electric push rod 20 pushes the grinding wheel 17. The first motor 10 is started, driving the screw 8 to rotate. With the threaded engagement between the screw 8 and the moving block 12, and the guiding engagement of the slide rod 9, the support arm 3 can drive the horizontal arm 4 to... The grinding wheel 17 moves along the length of the processing table 1 to adjust the grinding position of the metal tube. Furthermore, the side of the grinding wheel 17 that grinds the metal tube rotates downwards, and the second motor 15 drives the three-jaw chuck 14 to rotate the metal tube in the opposite direction to the grinding wheel 17. During the grinding process of the grinding wheel 17 on the metal tube, the generated metal powder will splash towards the processing table 1. By starting the vacuum cleaner 11, the metal powder generated during polishing can be removed as much as possible, reducing the pollution of metal powder to the environment. In addition, since the screw 8 and slide bar 9 used to drive the translation of the grinding wheel 17 are located below the processing table 1, the phenomenon of metal powder generated during polishing adhering to the surface of the screw 8 and slide bar 9 and affecting the normal movement and adjustment of the grinding wheel 17 is avoided, ensuring the smoothness of the metal tube polishing process.
[0031] All technical features in this embodiment can be freely combined according to actual needs.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
