Description

Technical Field

[0001] This utility model relates to the field of centerless lathe technology, specifically to a high-efficiency centerless lathe. Background Technology

[0002] In the machining industry, centerless lathes are used for machining the outer diameter of workpieces such as shafts and discs. They are key equipment in precision manufacturing and are usually composed of a grinding mechanism, a support, a guide wheel mechanism, and a bed. The grinding mechanism contains a grinding wheel (or grinding roller or other grinding components), which is the key part that directly cuts the workpiece. It achieves grinding of the outer diameter surface of the workpiece through high-speed rotation. It is also equipped with a drive motor and transmission device to provide power to the grinding components.

[0003] Existing centerless lathes have significant drawbacks in use. Firstly, their workpiece clamping structure is simplistic, resulting in poor adaptability to workpieces of different sizes and shapes, making stable clamping difficult and affecting machining accuracy and efficiency, thus failing to meet the demands of high-precision parts. Secondly, they lack flexible protection and precise positioning mechanisms, making workpiece surface easily damaged during clamping, and the workpiece positioning datum is prone to change, increasing machining errors. Therefore, we need to upgrade and modify existing technologies. Utility Model Content

[0005] To solve the above problems, the following technical solutions are provided: Design a high-efficiency centerless lathe, including a device body with a base inside. A worktable is connected above the base. The worktable is equipped with two electric slide rails. The first electric slide rail is connected to a sliding frame, on which a controller and a grinding roller are mounted. The second electric slide rail is connected to a sliding frame, on which a controller and a grinding roller are mounted. The worktable also has an annular seat and a square plate. The annular seat is connected to a U-shaped frame. A top plate is mounted on the U-shaped frame. The top plate is connected to a mounting frame.

[0006] Furthermore, the controllers 1 and 2 have built-in PID control algorithms, supporting stepless speed adjustment and adapting to multi-process continuous processing.

[0007] Furthermore, the electric slide rail one and electric slide rail two are driven by linear servo motors and equipped with grating ruler feedback.

[0008] Furthermore, the first and second clamping plates are quick-change structures, with removable wear-resistant pads on the clamping surfaces. The pad surfaces are machined with V-shaped and arc-shaped grooves to accommodate shaft and disc workpieces.

[0009] Furthermore, the spring is made of a high-temperature resistant alloy with a low elastic decay rate, ensuring long-term stability of the clamping force.

[0010] Furthermore, the protective pad is coated with a nano-ceramic composite coating, which is wear-resistant and prevents scratches on the workpiece.

[0011] Furthermore, the positioning plate is a three-dimensional adjustable structure, which can be finely adjusted along the X, Y, and Z axes by bolts to adapt to different workpiece reference corrections.

[0012] Furthermore, the outer shell of the device body is integrated with a soundproof cover, which adopts a double-layer damping sound insulation structure and has a dust collection channel inside, which is combined with negative pressure dust collection.

[0013] Furthermore, the surfaces of the first and second grinding rollers are provided with detachable abrasive sleeves.

[0014] Furthermore, the U-shaped frame and the ring seat are rotatably connected, and with the adjustment of the square plate angle, multi-faceted processing of the workpiece can be achieved, improving processing adaptability.

[0022] Preferably, controller 1 (8) and controller 2 (10) incorporate PID control algorithms, supporting stepless speed adjustment, adapting to multi-process continuous processing, ensuring surface quality, reducing debugging time, and improving batch production efficiency. Electric slide rail 1 (4) and electric slide rail 2 (5) are driven by linear servo motors and equipped with grating ruler feedback to realize device displacement, ensuring accurate grinding roller processing trajectory and improving device processing efficiency. Clamping plates 1 (17) and 2 (18) are quick-change structures with removable wear-resistant pads on the clamping surfaces. The pad surfaces are machined with V-shaped and arc-shaped grooves, adapting to shaft and disc workpieces, enabling the handling of diverse orders without downtime for equipment changes, shortening production changeover time, reducing spare parts costs, and extending device lifespan.

[0023] Preferably, the spring 22 is made of high-temperature resistant alloy material with low elastic decay rate, ensuring long-term stability of clamping force, ensuring workpiece clamping consistency, and reducing machining deviations caused by changes in clamping force. The protective pad 23 adopts a nano-ceramic composite coating, which is wear-resistant and prevents workpiece scratches.

Controller 1 (8) and Controller 2 (10) independently control the rotational speed and feed rate of Grinding Roller 1 (9) and Grinding Roller 2 (11), respectively, supporting simultaneous or step-by-step processing of multiple processes. The electric slide rail works in conjunction with the controller to achieve efficient cutting and polishing of the outer diameter of the clamped workpiece by the grinding rollers according to the processing technology planning trajectory. The linkage of multiple components ensures processing accuracy and efficiency.
