DETAILED DESCRIPTION

[0021] The embodiments described below are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The movable end of the screw module is provided with the telescopic module 209, and the telescopic end of the telescopic module 209 is provided with a detachable mounting position, on which the lathe blade 206 or the grinding disc is detachably arranged; the sensor mechanism is arranged on a side of the telescopic module 209 close to the device body 101, for detecting the gap between the lathe blade 206 or the grinding disc and the wheel and the position of the wheel; the input end of the control mechanism is connected to the sensor assembly, and the output end of the control mechanism is connected to the processing mechanism 2.

[0023] It should be noted that during use, the wheel is first firmly clamped on the lathe using the clamping module, and then the sensor mechanism is responsible for detecting the position and gap of the wheel. After the sensor detects the data, the control mechanism receives and processes the information, and then adjusts the screw module in the processing mechanism 2 to move in the horizontal direction. Subsequently, the screw module is extended so that the lathe blade 206 is close to the wheel surface. At this time, the rotating assembly 20 is started, driving the wheel to rotate, and the screw module moves the lathe blade 206 in the horizontal direction. In this process, the lathe blade 206 generates multiple annular or threaded grooves on the wheel surface. Once the notch is generated, the wheel surface is polished by replacing the lathe blade 206 on the detachable mounting position with a grinding disc. At this time, the rotating assembly 20 continues to drive the wheel to rotate at high speed, so that the wheel surface generates heat by friction, so that the notch surface of the annular or threaded groove is polished flat. After the polishing is completed, the anti-skid groove on the tire wheel surface is generated.

[0024] Preferably, the telescopic assembly 10 comprises a driving cylinder 102, a positioning ring 103 and a movable rod 104, wherein the driving cylinder 102 is mounted on two opposite fixed plates 10111011 of the device body 101, the positioning ring 103 is mounted on the side of the fixed plate 1011 away from the driving cylinder 102, the movable rod 104 is movably mounted on the transmission end of the driving cylinder 102, and the outer surface of the movable rod 104 is slidably connected to the ring body opened by the positioning ring 103. When in use, the driving cylinder 102 is controlled to make the movable rod 104 extend outward, and the positioning ring 103 ensures that the movable rod 104 moves in the axial position. At this time, the clamping modules on both sides firmly clamp the wheel on the lathe through the movement of the movable rod 104. Therefore, the telescopic assembly 10 can flexibly adjust the clamping position of the wheel, adapt to wheels of different sizes and shapes, and improve the applicability and flexibility of the equipment.

[0025] Preferably, the rotating assembly 20 includes a driving motor 105, a transmission rod 106 and a clamping piece 107. The driving motor 105 is fixedly mounted on the end of the movable rod 104, the transmission rod 106 is movably mounted on the transmission end of the driving motor 105, and the clamping piece 107 is detachably mounted on the end of the transmission rod 106. When in use, the driving cylinder 102 controls the movable rod 104 to extend outward, thereby driving the rotating assemblies 20 on both sides to move closer to the opposite side. At this time, the clamping pieces 107 at both ends extend into the wheel to fix the wheel. When it is necessary to generate an anti-skid groove on the wheel surface, the lathe blade 206 or the grinding disc is against the wheel surface and provides pressure to the wheel surface. At this time, the driving motor 105 drives the transmission rod 106 to rotate, thereby driving the wheel to rotate, so that the lathe blade 206 generates an anti-skid groove on the wheel surface. The detachable installation of the clamping piece 107 makes the clamping piece 107 replaceable, thereby enabling the lathe to adapt to wheels of different shapes and sizes, thereby improving the applicability and flexibility of the equipment, and also reducing the mold change time and cost.

[0026] Preferably, the clamping piece 107 is a clamping piece 107 with a "convex" cross-section, and the outer diameter of the small diameter section of the "convex" clamping piece 107 is the same as the inner diameter of the wheel. When in use, the small diameter section of the "convex" clamping piece 107 extends into the wheel, and the end surface of the large diameter section close to the small diameter section abuts against the side of the wheel. As another preferred solution, the clamping piece 107 is a conical clamping piece 107.

[0027] Preferably, the screw module comprises a servo motor 202, a ball screw 203, a ball nut 205 and a rotating shaft 204. The servo motor 202 is arranged on the top plate 201 of the device. The output end of the servo motor 202 is connected to the ball screw 203. The end of the ball screw 203 away from the servo motor 202 is rotatably connected to the rotating shaft 204 arranged on the top plate 201 of the device. The side of the ball nut 205 close to the wheel fixing mechanism 1 is provided with the telescopic module 209. By controlling the rotation of the servo motor 202, the ball screw 203 and the ball nut 205 cooperate to drive the lathe blade 206 or the grinding disc to process along the wheel surface. Therefore, all parts of the wheel surface can be processed.

[0028] Furthermore, the telescopic module 209 is an electric telescopic rod or a hydraulic telescopic rod.

The proximity sensor, the photoelectric sensor or the laser sensor has high precision and sensitivity, and can accurately detect the position and gap of the wheel, thereby ensuring the accuracy and stability of the processing process. Specifically, the position of the wheel surface can be detected through detection, and then the telescopic module 209 drives the lathe blade 206 or the grinding disc to move within the wheel range, so that a threaded anti-skid groove or a plurality of annular anti-skid grooves are generated on the outer periphery of the wheel. At the same time, the spacing between the wheel surface and the lathe blade 206 or the grinding disc can also be controlled so that the anti-skid groove can be generated and polished. Preferably, the control module is a PLC controller. Using a PLC controller as a control module can improve the wheel surface processing to achieve automated control and precise processing, thereby improving processing efficiency and product quality. Preferably, a control button 208 and a control panel 207 are also provided.

[0030] The wheel surface processing lathe provided by the utility model comprises a wheel fixing mechanism 1, a processing mechanism 2, a sensor mechanism and a control mechanism. When in use, the wheel is fixed by the wheel fixing mechanism 1, and then the sensor mechanism detects the wheel position and the wheel gap. The control mechanism receives the data of the sensor mechanism and controls the screw module of the processing mechanism 2 to move in the horizontal direction. Then the control mechanism controls the extension of the telescopic module 209 so that the lathe blade 206 or the grinding disc is against the wheel. Then the rotating assembly 20 included in the wheel fixing mechanism 1 drives the wheel to rotate, thereby turning a spiral pattern on the wheel surface. Therefore, the wheel surface processing lathe is provided with a sensor mechanism, so that the detection of the wheel position and gap is automated without manual intervention. After receiving the sensor data, the control mechanism can automatically and accurately adjust the lathe blade 206 or the grinding disc to press against the wheel, thereby realizing the automated control of the entire processing process and greatly improving the production efficiency. It has the advantages of automated processing, precise control, flexible adaptability, and high production efficiency.
