When the clamped workpiece is processed, the fixed frame moves to the bottom of the nozzle, and a part of the sprayed cutting fluid is poured onto the surface of the workpiece from the top liquid inlet hole, and the two groups of inclined cooling fans on the top assist in cooling the cutting fluid, so as to avoid the workpiece from being brittle due to high temperature during the grinding process.

[0016] The present invention provides a full-function CNC horizontal roller ring grinding machine, which drives a screw rod to rotate through a servo motor, and a moving block on the surface drives a concave plate to move in the Y-axis direction along the surface of a guide rod. During the movement, a servo motor drives a screw rod to rotate, so that the T-shaped moving block drives a grinding wheel frame to move in the X-axis direction on the surface of a guide rail. By performing a bidirectional displacement on the grinding wheel frame, it is ensured that the grinding wheel on the grinding wheel frame can be quickly positioned when grinding a workpiece. At the same time, the displacement of the concave plate and the displacement of the grinding wheel frame are controlled by a separately arranged grating ruler displacement sensor to ensure the accuracy during grinding and the processing quality of the workpiece.

At the same time, a grating scale displacement sensor is used to locate the moving distance, thereby increasing the grinding accuracy. Example 2

[0022] like Figure 1-5As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, a grille 17 is fixedly installed on the back side of the outer cover 12 and on both sides of the dust exhaust groove 16, the inner side of the grille 17 is rotatably connected to an exhaust fan 18, the back side of the grille 17 is fixedly installed with a dust exhaust pipe 19, the top of the machine tool base 11 is fixedly connected with a V-groove guide rail 116, the top of the machine tool base 11 is fixedly connected with a column 113, the inner side of the column 113 is rotatably connected with a ball screw 115, the outer side of the column 113 is fixedly installed with a motor 114, and the output end of the motor 114 is fixedly connected to one end of the ball screw 115.

[0023] In this embodiment, when the workpiece needs to be processed, the front sealing plate 15 is pulled open to make it slide along the slide rail 14 on the back, thereby exposing the interior of the outer cover 12 and fixing the workpiece on the table panel 22.

Example 3

[0024] like Figure 1-5 As shown, based on Example 1, the present invention provides a technical solution: preferably, a fixing frame 24 is fixedly connected to the top of the table panel 22, and a cylinder 25 is fixedly installed on both sides of the fixing frame 24. A liquid inlet hole 26 is opened at the top axis of the fixing frame 24 and directly below the nozzle 112, and a cooling fan 27 is rotatably connected to the inner top of the fixing frame 24.

[0025] In this embodiment, the workpiece to be processed is placed in the middle of the two groups of cylinders 25, and the two groups of cylinders 25 are started synchronously to clamp the workpiece from both sides. When the ball screw 115 rotates, the balls in the ball nut 28 roll along the threads on the surface of the ball screw 115, and enter the reverser after rolling one circle to prevent the nut body from rotating, and convert the rotary motion into linear motion. When the clamped workpiece is processed, the fixed frame 24 moves to the bottom of the nozzle 112, and a part of the sprayed cutting fluid will be poured onto the surface of the workpiece from the top liquid inlet hole 26, and the two groups of inclined cooling fans 27 on the top assist in cooling the cutting fluid, so as to avoid the workpiece from being brittle due to high temperature during the grinding process. Example 4

[0026] like Figure 1-5 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the output end of the servo motor 38 is fixedly connected to the screw rod 39 inside the concave plate 37, the surface of the concave plate 37 is fixedly connected to the guide rail 310, the surface of the guide rail 310 and the surface of the screw rod 39 are movably connected to a T-shaped moving block 311, the top of the T-shaped moving block 311 is fixedly connected to a grinding wheel frame 312, the inner side of the grinding wheel frame 312 is rotatably connected to a grinding wheel 313, the outer side of the grinding wheel frame 312 is fixedly connected to a rotating motor 314, and the output end of the rotating motor 314 is fixedly connected to one end of the grinding wheel 313.

[0027] In this embodiment, the servo motor 1 32 drives the screw rod 1 35 to rotate, and the surface moving block drives the concave plate 37 to move in the Y-axis direction along the surface of the guide rod 34. While moving, the servo motor 2 38 drives the screw rod 2 39 to rotate, so that the T-shaped moving block 311 drives the grinding wheel frame 312 to move in the X-axis direction on the surface of the guide rail 310. By performing bidirectional displacement on the grinding wheel frame 312, it is ensured that the grinding wheel 313 on the grinding wheel frame 312 can be quickly positioned when grinding the workpiece. At the same time, the displacement of the concave plate 37 and the displacement of the grinding wheel frame 312 are controlled by separately arranged grating scale displacement sensors to ensure the accuracy during grinding and the processing quality of the workpiece.

[0028] The following is a detailed description of the working principle of this full-function CNC horizontal roller ring grinder.

[0029] like Figure 1-5As shown, when the workpiece needs to be processed, the front cover 15 is opened to slide along the slide rail 14 on the back, thereby exposing the inside of the outer cover 12, and the workpiece to be processed is placed in the middle of the two groups of cylinders 25, and the two groups of cylinders 25 are started synchronously to clamp and fix the workpiece from both sides. When processing is performed, the motor 114 drives the ball screw 115 to rotate. When the ball screw 115 rotates, the ball in the ball nut 28 rolls along the thread on the surface of the ball screw 115, and enters the reverse device after rolling one circle to allow the screw to rotate. The mother body will not rotate, and the rotary motion is converted into linear motion, so that the table plate 22 slides on the surface of the V-groove guide rail 116 through the connecting plate 21. During the sliding process, the moving ruler part of the grating ruler 117 follows the movement, so as to make the moving distance more accurate. When processing the workpiece, the pump 111 will extract the cooling cutting fluid in the water tank 110 and discharge it through the nozzle 112, and spray it on the processed workpiece. The fixed frame 24 follows and moves to the bottom of the nozzle 112, and a part of the sprayed cutting fluid will be poured on the surface of the workpiece from the top liquid inlet hole 26. , and the two groups of inclined cooling fans 27 on the top assist in cooling the cutting fluid, so as to avoid the brittle cracking of the workpiece due to high temperature during the grinding process. The servo motor 1 32 drives the screw 1 35 to rotate, and the surface moving block drives the concave plate 37 to move in the Y-axis direction along the surface of the guide rod 34. While moving, the servo motor 2 38 drives the screw 2 39 to rotate, so that the T-shaped moving block 311 drives the grinding wheel frame 312 to move in the X-axis direction on the surface of the guide rail 310. By performing bidirectional displacement on the grinding wheel frame 312, The grinding wheel 313 on the grinding wheel frame 312 can be quickly positioned when grinding the workpiece. At the same time, the displacement of the concave plate 37 and the displacement of the grinding wheel frame 312 are controlled by a separately set grating scale displacement sensor to ensure the accuracy of grinding and the processing quality of the workpiece. At the same time, during the grinding process, the debris generated by the workpiece will generate suction through the exhaust fan 18, so that the debris passes through the grille 17 and enters the dust exhaust pipe 19 for exhaust, thereby ensuring that there is a good cooling and dust removal system during the workpiece processing process to ensure the grinding quality.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
