Description

Technical Field

[0001] This utility model relates to the field of titanium rod polishing technology, and in particular to a titanium rod belt polishing machine. Background Technology

[0002] Titanium rods are cylindrical strips made of pure titanium or titanium alloys. They are widely used in many fields, mainly due to their excellent corrosion resistance, high strength-to-weight ratio, and good biocompatibility. Polishing titanium rods is to improve their surface smoothness and aesthetics, while also helping to remove surface defects and reaction layers, thereby improving their physical and chemical properties and service life.

[0003] Existing titanium rod polishing equipment mostly uses the friction between a high-speed rotating abrasive wheel and the titanium rod for polishing. However, this method has problems such as uneven polishing and easy damage to the surface of the titanium rod. In addition, some polishing equipment has a complex structure and is cumbersome to operate, which is not conducive to improving production efficiency and reducing production costs. Therefore, it is necessary to design a new type of titanium rod abrasive belt polishing machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing titanium rod polishing equipment that uses the friction between a high-speed rotating grinding wheel and a titanium rod for polishing, which results in uneven polishing and easy damage to the surface of the titanium rod. Therefore, this invention proposes a titanium rod belt polishing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A titanium rod belt polishing machine includes a base, a housing fixedly mounted on the top of the base, a clamping box fixedly mounted on the top of the base at the opening side of the housing, a support plate fixedly mounted on the bottom inner wall of the housing, and a fixing plate fixedly mounted on the top of the support plate. Both the housing and the fixing plate have openings for the passage of titanium rods, and the two openings are connected. The polishing machine also includes:

[0007] Two sets of polishing components are symmetrically arranged on one side of the fixed disk for polishing titanium rods.

[0008] Clamping assembly, which is mounted on the clamping box, is used to clamp the titanium rod during grinding.

[0009] In one possible design, the polishing assembly includes a rotating plate with a connecting pipe fixedly connected to the side of the rotating plate near the fixed disk. The connecting pipe is rotatably connected to one side of the fixed disk. A rotating shaft is rotatably connected to the side of the rotating plate away from the fixed disk. A first sanding belt wheel is fixedly sleeved on the rotating shaft. One end of the rotating shaft passes through the rotating plate and the fixed disk and extends to the outside of the housing. The rotating shaft is rotatably connected to both the rotating plate and the fixed disk, and passes through the connecting pipe. A second motor is fixedly connected to one side of the housing. The output end of the second motor is fixedly connected to the rotating shaft. A limit block is slidably provided at the bottom of the rotating plate. A second sanding belt wheel is rotatably connected to one side of the limit block. The first sanding belt wheel and the second sanding belt wheel are drivenly connected to the same sanding belt.

[0010] In one possible design, the polishing assembly further includes a first cylinder rotatably mounted on one side of the fixed disk. The first cylinder and the rotating plate are located on the same side. The top of the rotating plate has a first sliding hole, and a connecting seat is rotatably connected in the first sliding hole. The connecting seat is fixedly connected to the output end of the first cylinder. A limit screw is rotatably connected to the connecting seat via the rotating seat. A fixed seat is fixedly mounted on one side of the fixed disk, and a connecting positioning shaft is rotatably connected to one side of the fixed seat. A positioning hole is opened on the positioning shaft, and the limit screw passes through the positioning hole and is threadedly connected to a bolt for limiting the position above the positioning shaft.

[0011] In one possible design, the top of the rotating plate has a second sliding hole, the top of the limiting block passes through the second sliding hole and is slidably connected to the second sliding hole, and the top of the rotating plate is fixedly connected to both sides of the second sliding hole. The same adjusting screw is rotatably connected to the side of the two fixed plates that are close to each other. The adjusting screw is threaded through the limiting block, and one end of the adjusting screw extends to the outside of one of the fixed plates.

[0012] In one possible design, a limiting wheel is rotatably connected to one side of the rotating plate, and the limiting wheel contacts the inner wall of the sanding belt.

[0013] In one possible design, the clamping assembly includes four guide wheels arranged in pairs, one above the other. The two lower guide wheels are rotatably connected to one side of the clamping box via a first drive shaft, and each of the two first drive shafts is fixedly fitted with a sprocket. The two sprockets are connected to the same chain. A sealing plate is provided at the opening of the clamping box, and a first motor is fixedly installed on one side of the sealing plate. The output end of the first motor passes through the sealing plate and is fixedly connected to one of the first drive shafts. A fixing frame is fixedly installed inside the clamping box, and a slider is slidably connected to the fixing frame. Two limiting ports are opened on one side of the clamping box. The two upper guide wheels are rotatably connected to the slider via a second rotating shaft, and the two second rotating shafts are located in the corresponding limiting ports. Two second cylinders are fixedly connected to the top of the clamping box, and the output ends of the two second cylinders are fixedly connected to the top of the slider.

[0014] In one possible design, the top of the housing is fixedly connected to two sliding rods by a fixing block, and the two sliding rods are arranged vertically. Two sealing doors slide through the two sliding rods, and each of the two sealing doors has an arc-shaped groove on the side that is close to each other, and the two arc-shaped grooves correspond to the opening.

[0015] In this application, firstly, the surface of the titanium rod is cleaned to ensure that the surface is clean and free of impurities. Then, the titanium rod to be polished is placed on the clamping assembly on the clamping box and clamped by the clamping assembly. Specifically, the clamping assembly includes four guide wheels. The two guide wheels located at the bottom rotate synchronously through the transmission of the first drive shaft, sprocket, and chain. The other two guide wheels located at the top move up and down by the push of the second cylinder, thereby achieving a firm clamping of the titanium rod. Then, the first motor is started, and the first motor drives the two guide wheels located at the bottom to rotate, thereby moving the clamped titanium rod towards the two sets of polishing components.

[0016] Next, the second motors in both polishing components start simultaneously. The second motors drive the rotating shaft and the first abrasive belt wheel to rotate. At the same time, the abrasive belt passes around the first and second abrasive belt wheels, and the tension is adjusted by the sliding of the limit block on the rotating plate. The first cylinder pushes the rotating plate and the abrasive belt close to the titanium rod. The abrasive belt contacts the surface of the titanium rod and polishes it. By adjusting the extension and retraction of the first cylinder, the polishing pressure can be controlled. The two second motors rotate in opposite directions, causing the two abrasive belts to rotate in opposite directions. The friction of the abrasive belts causes the titanium rod to move slowly to one side, completing the overall polishing of the titanium rod.

[0017] To achieve comprehensive and uniform polishing of titanium rods of different specifications, the position of the second abrasive belt wheel can be adjusted by adjusting the screw, thereby changing the contact angle between the abrasive belt and the titanium rod. At the same time, the setting of the limiting wheel can ensure the stable operation of the abrasive belt during the polishing process.

[0018] During the polishing process, sealing doors can be used to reduce the harm of dust to workers.

[0019] Beneficial effects: The titanium rod polishing machine of this utility model, by using two sets of polishing components for belt polishing, not only achieves better polishing effect, but also greatly improves the polishing efficiency of titanium rods and reduces the labor intensity of operators.

[0020] In this utility model, the titanium rod belt polishing machine, by setting two sets of adjustable symmetrical polishing components, can achieve comprehensive and uniform polishing of titanium rods, ensuring the consistency of polishing quality;

[0021] In this utility model, the titanium rod belt polishing machine, by setting an adjustable distance limit block and a second sanding belt wheel thereon, can not only adjust the tension of the sanding belt, but also facilitate the replacement of the sanding belt.

[0022] In this invention, by employing two sets of polishing components with abrasive belts, not only is the polishing effect better, but the polishing efficiency of titanium rods is also greatly improved, reducing the labor intensity of operators. By setting two sets of adjustable symmetrical polishing components, comprehensive and uniform polishing of titanium rods can be achieved, ensuring the consistency of polishing quality. Furthermore, the adjustable distance limit block and the second abrasive belt wheel on it can not only adjust the tension of the abrasive belt, but also facilitate the replacement of the abrasive belt.
