[0002] A centerless grinder is an external cylindrical grinding machine without a center hole support. It achieves efficient and high-precision external cylindrical machining by making the workpiece "centerless". It is widely used in mass production for external cylindrical grinding of rotating parts such as shafts and sleeves.

[0003] According to the patent titled "A Centerless Grinding Machine" (Patent Publication No.: CN206393371U, Patent Publication Date: 2017-08-11), the machine includes a bed. A guide wheel feed mechanism is fixedly mounted on the upper surface of the bed. A guide wheel motor is fixedly mounted inside the guide wheel feed mechanism. A guide rail is provided outside the guide wheel feed mechanism. A guide wheel is fixedly connected to the end of the guide rail away from the guide wheel motor. The upper side of the bed is fixedly connected to the output shaft of a servo motor via the guide wheel feed mechanism. The upper end of the guide wheel feed mechanism is movably connected to a grinding wheel dresser via the guide rail. The grinding wheel dresser is fixedly connected to a grinding wheel housing via the guide rail. A grinding wheel is fixedly mounted on the inner side of the grinding wheel housing. A workpiece to be processed is placed between the grinding wheel and the guide wheel. By using a servo motor-driven feed device, automatic dressing and automatic compensation are achieved in the centerless grinding machine. A water gun is also included; water is sprayed onto the workpiece during processing to reduce the temperature of the grinding wheel, guide wheel, and workpiece.

[0004] Based on the aforementioned existing technologies, current fully automatic centerless grinding equipment controlled by servo motors still has the following problems: existing equipment typically requires operators to manually place the workpieces to be processed one by one into the grinding position or the starting point of the feeding mechanism. This is not only slow, limiting the overall cycle time of the equipment, but also makes it impossible to achieve true continuous production. Therefore, this utility model provides a fully automatic centerless grinding equipment controlled by servo motors. Utility Model Content

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] Please see Figures 1-6 This utility model provides a technical solution:

[0026] A fully automatic centerless grinding machine based on servo motor control includes a centerless grinding machine mechanism 1. A feeding mechanism 2 is provided on the front side of the centerless grinding machine mechanism 1 for automatic feeding of the material bar. The feeding mechanism 2 includes:

[0027] The feeding unit 21 is located on the front side of the centerless grinding machine mechanism 1. It includes a feeding box 211. A mounting frame 212 is fixedly installed at the bottom of the feeding box 211. A first rotating shaft 213 and a second rotating shaft 216 are rotatably installed inside the mounting frame 212. A first synchronous pulley 214 is fixedly installed on the surface of the first rotating shaft 213, and a second synchronous pulley 215 is fixedly installed on the surface of the second rotating shaft 216. A synchronous belt 217 is installed between the first synchronous pulley 214 and the second synchronous pulley 215. A set of push rods 219 are fixedly installed on the surface of the synchronous belt 217. The first synchronous pulley 214 and the second synchronous pulley 215 cooperate with the first rotating shaft 213 and the second rotating shaft 216 to rotate, thereby driving the push rods 219 to rotate and push the material bar, thus realizing automatic feeding of the material bar. An adjustment component 3 is provided on the rear side of the feeding box 211 to limit the discharge of a single material bar.

[0028] The adapter unit 22 is located inside the feeding box 211 and is used to adapt and feed material bars of different specifications and sizes.

[0029] In this embodiment, a servo motor 218 is fixedly installed on the right side of the mounting bracket 212, and the output end of the servo motor 218 passes through the mounting bracket 212 and is fixedly connected to the right end of the second rotating shaft 216.

[0030] The model is EDSMT-2T110-020A. It is electrically connected to an external power supply and can be started and stopped by personnel through the control panel. The servo motor 218 directly drives the synchronous belt 217 and the push rod 219 to realize the start and stop of the material bar pushing and the speed is adjustable.

[0031] In this embodiment, the adapter unit 22 includes a set of movable plates 222 slidably installed inside the feeding box 211. A bidirectional lead screw 221 is rotatably installed inside the mounting frame 212, and the lower end of the movable plate 222 is threadedly rotatably installed on the surface of the bidirectional lead screw 221. A handwheel rotating rod 225 is fixedly installed on the left end of the bidirectional lead screw 221. The bidirectional lead screw 221 is driven to rotate by the handwheel rotating rod 225. The rotation of the bidirectional lead screw 221 realizes that the movable plates 222 move towards each other, so that material bars of different specifications and sizes are arranged and placed inside the feeding box 211.

[0032] Rotating the double-acting screw 221 by the handwheel 225 drives the two moving plates 222 to move towards each other. The distance between the moving plates 222 is adjustable to accommodate workpieces of different diameters.

[0033] In this embodiment, limit grooves 224 are provided on both the front and rear sides of the material feeding box 211, and limit blocks 223 are fixedly installed at the front and rear ends of the moving plate 222. The limit blocks 223 slide inside the limit grooves 224 to limit the movement of the moving plate 222.

[0034] The movable plate 222 slides within the limiting groove 224 of the feeding box 211 via the limiting block 223. The limiting groove 224 constrains the direction of movement to prevent skewing or jamming.

[0035] In this embodiment, the adjustment component 3 includes a track frame 31 fixedly installed on the rear side of the feeding box 211. A baffle 32 is slidably installed inside the track frame 31. A threaded sleeve block 33 is fixedly installed on the rear side of the feeding box 211. A threaded post 34 is rotatably installed inside the threaded sleeve block 33. The bottom end of the threaded post 34 is rotatably connected to the top of the baffle 32.

[0036] The rotating threaded column 34 drives the baffle 32 to rise and fall within the track frame 31, controlling the height of the discharge port.

[0037] In this embodiment, the centerless grinding machine mechanism 1 includes a frame 11, and a feeding box 211 is fixedly installed on the front side of the frame 11. A grinding wheel module 12, a guide wheel module 13 and a tray frame 14 are arranged on the top of the frame 11.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] During operation, the user first rotates the handwheel 225 to drive the double-acting screw 221 to rotate. The double-acting screw 221 drives the two moving plates 222 to move towards each other. The appropriate distance between the two moving plates 222 is adjusted to suit the material bar to be processed, and the material bar is placed between the two moving plates 222.

[0040] Next, turning the knob above the threaded column 34 causes the threaded column 34 to rotate, which in turn drives the baffle 32 to move up and down, adjusting the space below the baffle 32 to a suitable outlet space for a single material bar.

[0041] Then, the servo motor 218 runs, driving the second rotating shaft 216 to rotate. The second rotating shaft 216 drives the second synchronous pulley 215 to rotate. The second synchronous pulley 215 drives the first synchronous pulley 214 and the first rotating shaft 213 to rotate via the synchronous belt 217. The synchronous belt 217 drives the two push rods 219 to rotate. The push rods 219 push the material bar inside the feeding box 211 through the space below the baffle 32 into the interior of the pallet frame 14. The grinding wheel module 12 and the guide wheel module 13 move towards each other to process the material bar.
