Technical Field

[0001] The utility model relates to the technical field of precision machining, in particular to a precision machining adaptive error compensation device. Background Art

[0002] Precision machining plays a very important role in the manufacturing industry and is often used in the machining of key parts such as precision screws, precision gears, precision worm gears, precision guide rails and precision bearings. Precision machining refers to machining with a machining accuracy of 10 to 0.1 microns and a surface roughness of less than 0.1 microns.

[0003] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: during the precision machining of the workpiece, the workpiece will be cut. During cutting, the cutting disc will be worn to varying degrees, causing the cutting disc to become passivated, thereby reducing the cutting efficiency of the cutting disc on the workpiece; therefore, a precision machining adaptive error compensation device is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a precision machining adaptive error compensation device, which has the advantage of compensating for the wear of the cutting disc, and solves the problem that during the precision machining process of the workpiece, the workpiece will be cut. During cutting, the cutting disc will have different degrees of wear, resulting in passivation of the cutting disc and reducing the cutting efficiency of the cutting disc on the workpiece.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precision machining adaptive error compensation device, comprising a base, a mounting plate fixedly installed on the left side of the top of the base, a cylinder fixedly installed on the top of the mounting plate, a mounting frame fixedly installed on the output end of the cylinder, a motor fixedly installed on the right side of the mounting frame, a cutting disk rotatably connected to the inner side of the mounting frame, the output end of the motor is fixedly connected to the cutting disk, two compensation mechanisms are fixedly installed on the top of the inner side of the mounting frame, the two compensation mechanisms are respectively located on the sides of the cutting disk, and limiting clamps are fixedly installed on both sides of the top of the base.

[0006] The effect achieved by the above components is: by setting up a compensation mechanism to compensate for the cutting wear of the cutting disc, the cutting edge of the cutting disc is prevented from being blunted after long-term cutting, which reduces its cutting effect, thereby improving the cutting effect and efficiency of the cutting disc on the workpiece; by setting up a cylinder to drive the mounting frame to move up and down, the cutting disc is driven to rotate under the action of the motor; when the mounting frame moves downward, the mounting frame drives the motor and the cutting disc to move downward, and then the cutting disc cuts the workpiece fixed between the limit clamps; after cutting is completed, the mounting frame is driven to rise, so that the cutting disc is separated from the workpiece.

[0007] Preferably, the compensation mechanism includes a fixed frame, which is fixedly installed on the top of the inner side of the mounting frame, the inner side of the fixed frame is rotatably connected to a rotating drum, the bottom of the rotating drum is fixedly installed with a connecting frame, a grinding wheel is provided on the inner side of the connecting frame, a transmission plate is fixedly installed on the top of the rotating drum surface, a spring is fixedly installed on the top of the mounting frame, a pressure plate is fixedly installed on the top of the spring, a transmission rod is fixedly installed on the bottom of the pressure plate, and the bottom of the transmission rod passes through the top of the mounting frame and extends to the top of the transmission plate.

[0008] The effect achieved by the above components is: when the mounting frame rises, the pressure plate will be squeezed by the bottom of the mounting plate, so that the pressure plate drives the transmission rod to move downward, and then the transmission rod will squeeze the transmission plate. At this time, the pulley slides on the surface of the transmission plate and squeezes the transmission plate. The spring is in a compressed state.

[0010] The effect achieved by the above components is: by setting a torsion spring to rotate and bounce the rotating drum, the rotating drum drives the connecting frame and the grinding wheel away from the cutting disk, thereby preventing the grinding wheel from interfering with the cutting of the workpiece by the cutting disk.

[0011] Preferably, a groove is provided at the bottom of the transmission rod, and a pulley is rotatably connected inside the groove, and the pulley is located on the top of the transmission plate.

[0012] The effect achieved by the above components is: by arranging the pulley to reduce the friction force when the transmission rod presses the transmission plate, it is easier for the transmission rod to press the transmission plate.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] The utility model provides a compensation mechanism to compensate for the cutting wear of the cutting disc, so as to avoid the blunting of the cutting edge of the cutting disc after long-term cutting, thereby reducing its cutting effect, thereby improving the cutting effect and efficiency of the cutting disc on the workpiece. A cylinder is provided to drive the mounting frame to move up and down, and the cutting disc is driven to rotate under the action of the motor. When the mounting frame moves down, the mounting frame drives the motor and the cutting disc to move down, and then the cutting disc cuts the workpiece fixed between the limit clamps.

[0026] Specifically, the compensation mechanism 2 includes a fixed frame 201, which is fixedly installed on the top of the inner side of the mounting frame 5, and the inner side of the fixed frame 201 is rotatably connected to a rotating drum 202, and a connecting frame 203 is fixedly installed on the bottom of the rotating drum 202, and a grinding wheel 204 is arranged on the inner side of the connecting frame 203, and a transmission plate 205 is fixedly installed on the top of the surface of the rotating drum 202, and a spring 208 is fixedly installed on the top of the mounting frame 5, and a pressure plate 207 is fixedly installed on the top of the spring 208, and a transmission rod 206 is fixedly installed on the bottom of the pressure plate 207, and the bottom of the transmission rod 206 passes through the top of the mounting frame 5 and extends to the top of the transmission plate 205.

[0027] Specifically, a fixing rod is fixedly installed on the inner side of the fixing frame 201 , and the fixing rod penetrates the interior of the rotating drum 202 , and the rotating drum 202 and the fixing rod are rotationally connected via a torsion spring.

[0028] The torsion spring is used to rotate and bounce the rotating drum 202, so that the rotating drum 202 drives the connecting frame 203 and the grinding wheel 204 away from the cutting disk 7, so as to prevent the grinding wheel 204 from interfering with the cutting of the workpiece by the cutting disk 7.

[0029] Specifically, a groove is formed at the bottom of the transmission rod 206 , and a pulley 209 is rotatably connected inside the groove. The pulley 209 is located on the top of the transmission plate 205 .

[0030] The pulley 209 is used to reduce the friction force when the transmission rod 206 presses the transmission plate 205 , thereby facilitating the transmission rod 206 to press the transmission plate 205 .

Under the high-speed rotation of the cutting disk 7, the grinding wheel 204 grinds the cutting edge of the cutting disk 7 to compensate for the wear of the cutting disk 7 during cutting.
