Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, and more specifically, to a bar grinding machine. Background Technology

[0002] A bar grinding machine is a specialized piece of equipment used for surface treatment of bars. It is widely used in many industries such as metallurgy and machining. Centerless grinders are common equipment for bar grinding. These automated machines are specifically designed for precision bar surface grinding. They eliminate the need for center positioning and clamping of the bar, allowing for continuous processing. They efficiently remove oxide scale, scratches, cracks, and machining allowances from the bar surface, significantly improving surface finish and dimensional accuracy. Their compact structure includes core components such as grinding wheels, guide wheels, and support plates. They feature high automation, fast grinding efficiency, and strong stability, and are suitable for various applications. In mass production scenarios, when a centerless grinder is working, the bar stock is placed on a support plate and driven to rotate and feed axially by the friction of the guide wheel. The high-speed rotation of the grinding wheel provides the grinding power. The guide wheel controls the rotation speed and feed rate of the bar stock by adjusting its angle and speed. The axes of the grinding wheel and the guide wheel are at a certain angle, causing the bar stock to make a helical feeding motion under the action of friction and support force. The grinding wheel continuously grinds the surface defects of the bar stock, while the support plate ensures that the bar stock maintains a stable posture during the grinding process, ultimately achieving efficient and precise surface grinding. Since the support height position of bars of different sizes is different, it is necessary to perform support adjustment operations.

[0003] In related technologies, during the use of centerless grinders, the ground bar stock is typically moved and supported by installing a support wheel frame on the outside of the grinding wheel and guide wheel.

[0004] However, in the current use of centerless grinders, the support wheel frame is generally directly bolted to the top of the centerless grinder. Since different sizes of bar stock require different support heights, the support wheel frame is difficult to support bar stock of different sizes, which affects the support flexibility and adaptability of the centerless grinder.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a bar grinding machine, including a grinding machine 1 and a bar support mechanism. A grinding wheel 2 is installed on the left side of the top of the grinding machine 1, and a guide wheel 3 is installed on the right side of the top of the grinding machine 1. The grinding wheel 2 and the guide wheel 3 can form a support medium that can be raised and lowered on both sides, so that the user can adjust the support height according to the actual size support requirements of the bar. This avoids the situation where it is difficult to support bars of different sizes when the grinding machine 1 is used, thus improving the support flexibility and adaptability of the grinding machine 1.

[0031] Reference Figures 1-4 In a preferred embodiment, the bar support mechanism includes a support frame 4, which is movably connected to both sides of the top of the grinding machine 1. Support wheels 5 are mounted on both sides of the support frame 4 via pins. A support plate 6 is fixedly connected to both sides of the top of the grinding machine 1. A support seat 7, fixedly connected to the support frame 4, is movably connected to the top of the support plate 6. A support lifting mechanism is located at the bottom of the support seat 7. Based on the actual support height required by the external bar dimensions, the support seat 7 is held in conjunction with the support frame 4 to move the support wheels 5 up and down, adjusting the support height of the support wheels 5 to match the support height of the bar. This allows the support wheel 5 to support the external rod. The support lifting mechanism includes a lifting cavity 8, a lifting seat 9, and a lifting groove 10. The lifting cavity 8 is located at the bottom of the support seat 7, and the lifting seat 9 is movably connected inside the lifting cavity 8. The bottom of the lifting seat 9 is fixedly connected to the top of the support plate 6. The lifting groove 10 is located on both sides of the lifting seat 9, which can guide the lifting connection between the support seat 7 and the support plate 6, so that the user can perform the lifting operation smoothly and avoid the support seat 7 from deviating from the support plate 6 during use. Therefore, the lifting connection effect between the support seat 7 and the support plate 6 is improved.

[0032] Reference Figures 2-3In a preferred embodiment, screw holes 11 communicating with lifting grooves 10 are provided at the bottom of both sides of the inner wall of the lifting cavity 8. Bolts 12 located inside the lifting grooves 10 are connected to the screw holes 11 internally. The lifting grooves 10 can restrict the lifting seat 9 and the lifting cavity 8 to prevent separation and tighten the lifting seat 9 and the lifting cavity 8 after lifting operation. This prevents the lifting seat 9 from detaching from the lifting cavity 8 or from being difficult to fix during use, thus improving the stability of the lifting seat 9. A screw groove 13 is provided at the top of the lifting seat 9. A screw rod 14 penetrating to the top of the support seat 7 and the support frame 4 is connected to the screw groove 13 internally. This provides a medium for the user to apply lifting adjustment force between the support seat 7 and the lifting seat 9, preventing the support seat 7 and the lifting seat 9 from being difficult to adjust during use, thus improving the ease of lifting adjustment of the support seat 7.

[0033] Reference Figures 2-4 In a preferred embodiment, connecting sleeves 15 are fixedly connected to both sides of the top of the support frame 4. A connecting frame 16 is movably connected inside the connecting sleeves 15. The bottom of the connecting frame 16 is fixedly connected to the top of the screw 14, which allows for rotational connection between the screw 14 and the support frame 4, preventing the screw 14 from separating from the support frame 4 during use. This improves the connection effect between the screw 14 and the support frame 4. A turntable 17 located outside the connecting sleeves 15 is fixedly connected to the top of the connecting frame 16. A rotating groove 18 is provided on the top of the turntable 17, which provides a force-applying medium for the user to rotate the connecting frame 16, preventing the connecting frame 16 from being difficult to rotate during use. This improves the ease of operation of the connecting frame 16.

[0034] Reference Figures 2-4 In a preferred embodiment, a magnetic groove 19 is provided on the top of the connecting frame 16, and a magnetic ring 20 magnetically connected to the connecting sleeve 15 is fixedly connected to the inner wall of the magnetic groove 19. The connecting frame 16 can be used to magnetically position the screw 14, avoiding the situation where the screw 14 is difficult to position during use, thus improving the positioning convenience of the screw 14. A magnetic cavity 21 is provided on the top of the inner wall of the connecting sleeve 15, and a magnetic ring 22 magnetically connected to the magnetic ring 20 is fixedly connected to the inner wall of the magnetic cavity 21. This can provide a medium for applying magnetic positioning force to the magnetic ring 20, avoiding the situation where the magnetic ring 20 is difficult to apply force during use, thus improving the magnetic force application effect of the magnetic ring 20.

[0035] Specifically, the working process or principle of this bar grinding machine is as follows: During use, based on the actual grinding support height required by the external bar dimensions, an external hex wrench is used to apply rotational force to the screw 14 through the rotating hole and the connecting frame 16 of the turntable 17. This causes the screw 14 to rotate and engage with the screw groove 13, applying a lifting thread thrust between the support frame 4, support seat 7, and lifting seat 9. This causes the support seat 7 to move the support wheel 5 up and down in conjunction with the support frame 4, adjusting the support height of the support wheel 5. At this time, the connecting frame 16 rotates inside the connecting sleeve 15, performing a rotational connection between the screw 14 and the lifting frame to prevent separation. Simultaneously, the magnetic ring 20 rotates with the connecting frame 16, preparing for subsequent magnetic positioning of the connecting frame 16. During this process, the lifting seat 9 is in the lifting cavity... 8. The internal movement of the support seat 7 and the support plate 6 is used to prevent the lifting connection wire from shifting. At the same time, the bolt 12 moves with the support seat 7 inside the lifting groove 10 to prevent the lifting seat 9 and the lifting cavity 8 from separating. After the support height of the support wheel 5 is adjusted, the magnetic ring 20 and the magnetic suction ring 22 are used to magnetically position the screw 14 and the support frame 4 through the connecting frame 16 and the connecting sleeve 15. Then, the bolt 12 is rotated to fit the screw hole 11, so that the bolt 12 moves inward and abuts against the inner wall of the lifting groove 10, which abuts and fixes the adjusted lifting seat 9 and the support seat 7, ensuring the height stability of the adjusted support seat 7. This allows the support frame 4 and the support wheel 5 to maintain the support height and support the bar material during the grinding process of the grinding wheel 2 and the guide wheel 3.

[0036] It should be noted that the grinding machine 1, grinding wheel 2 and guide wheel 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
