Description

TECHNICAL FIELD

[0002] The high-precision cutting device for gear machining is dedicated to precise machining of gears, precisely sets a grinding wheel dressing through a numerical control system, dresses the grinding wheel into a shape consistent with the gear tooth profile, ensures alignment with a gear blank to be machined according to the engagement rule during high-speed rotation, and cuts out a precise tooth surface circle by circle, so that the machining precision can reach the micron level. In the structural design, some high-precision composite cutting centers adopt artificial granite bed bodies, have good vibration absorption, high rigidity and high thermal stability, the grinding wheel frame integrates dynamic and static pressure shafts, and can simultaneously arrange multiple grinding wheels to meet different process requirements. The machine tool can usually control multiple numerical control shafts, such as four linear shafts and three rotary shafts, realize agile and flexible cutting of multiple processes, the grinding wheel frame movement is driven by a linear motor or a servo motor matched with a closed high-precision guide rail, and the precision, sensitivity and high response of the cutting feed are ensured. The workbench movement is driven by an alternating current servo-ball screw pair, and the workpiece rotation system is driven by a torque motor and an angle encoder, so that the rotation precision and dynamic responsiveness are very high. In addition, many devices are equipped with an automatic control system, and the whole process is automatically operated from gear clamping, parameter setting to machining monitoring, so that the production efficiency is greatly improved. The cutting force, temperature and other data can be monitored in real time through sensors, and the machining process is dynamically optimized.

[0003] The existing high-precision cutting device for gear machining has obvious limitations in the diversity of machining methods. Most traditional devices have single functions and can only realize machining of one type of gear, such as external circle cutting or tooth surface cutting. When non-circular gears, internal gears or double gears need to be machined, the traditional cutting device lacks matching clamping and cutting mechanisms and cannot complete machining of complex profiles. At the same time, most devices do not have the integration capability of multiple cutting processes, resulting in scattered machining processes, frequent replacement of equipment, reduced production efficiency, increased machining error risk caused by multiple clamping, and insufficient programming flexibility of the numerical control system of the equipment, which cannot quickly switch machining modes and cannot meet diversified production needs, thereby causing certain adverse effects on the use process of the people.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1, as Figures 1-5 As shown, when gear machining is required using the cutting tool 217, the first servo motor 21 is first started, causing the first servo motor 21 to drive the first deflection rod 22 to rotate, which in turn causes the positioning pin 23 to slide within the groove 25 of the deflection frame 24. Since the positioning pin 23 slides within the groove 25 inside the deflection frame 24, the rotation of the first deflection rod 22 causes the deflection frame 24 to deflect. Because the upper end of the deflection frame 24 is fixed to the first rotating block 26, the first rotating block 26 is simultaneously deflected. Furthermore, the end of the first rotating block 26 closest to the deflection frame 24 is fixed... A sector rack 27 is fixedly installed. The first rotating block 26 swings, causing the sector rack 27 to reciprocate. Since the sector rack 27 meshes with the first gear 29, the swing of the sector rack 27 drives the first gear 29 to rotate. Because one side of the first gear 29 is fixedly connected to one end of the linkage rod 210, the linkage rod 210 rotates. The linkage rod 210 then drives the fixedly connected eccentric block 211 to deflect, causing the eccentric block 211 to move eccentrically. When the eccentric block 211 deflects to the point that the electric telescopic rod 212... After the sliding column 213 is positioned correctly, the electric telescopic rod 212 is activated. As the electric telescopic rod 212 extends, it pushes the sliding column 213 to slide along the interior of the device base 1. When the electric telescopic rod 212 pushes the sliding column 213 into the interior of the device base 1, the rack 214 and the second gear 216 begin to mesh. Then, by activating the second servo motor 215, the second gear 216 is driven to continuously rotate forward and backward, thus driving the sliding column 213 and its fixedly connected cutting tool 217 to cut the gear. The rack 214 and the second gear 216... The meshing ensures smooth sliding, and the return spring 220 provides the return force. The cutting tool 217 at one end of the sliding column 213 or the rolling cutter 219 driven by the third servo motor 218 can be reversed when the rolling cutter 219 is required for processing. This allows the electric telescopic rod 212 to align with the sliding column 213 fixed to the third servo motor 218, pushing the sliding column 213, the third servo motor 218, and the rolling cutter 219 to the processing position for preparation. The cutting mode can be switched according to the processing requirements to achieve different processing actions on the gear.

[0021] Example 2, as Figures 5-11 As shown, when using the cutting tool 217 for machining, the fourth servo motor 32 is activated. The fourth servo motor 32 drives the first synchronous pulley 33 to rotate the second synchronous pulley 34 via a transmission belt. The second deflection rod 35 and the third deflection rod 36 cooperate to push the sliding block 39 to slide back and forth in the sliding groove 38 of the fixed seat 37. The first ratchet 311 on the sliding block 39 pushes the ratchet 313 to rotate in one direction, and the second ratchet 312 prevents reverse rotation. The ratchet 313 drives the first sprocket 314 to move the moving seat 317 along the deflection base 31 via the chain 315. The connecting block 318 slides on the side wall, realizing the pushing of the work station during the gap of the cutting tool 217's reciprocating cutting. The gear material moves slowly and briefly. The auxiliary telescopic rod 319 supports the moving seat 317. The fifth servo motor 320 drives the threaded rod 321 to move the first clamping plate 323 along the slide rod 322, which cooperates with the second clamping plate 324 to clamp the gear. The sixth servo motor 325 drives the rotating sliding sleeve 326 to rotate the gear, realizing positioning and angle deflection processing. When it is necessary to use the rolling cutter 219 for processing, the fourth servo motor 32 drives the first synchronous wheel 33 and the second synchronous wheel 34 to transmit power, so that the linkage structure drives the processing station to correspond with the position of the rolling cutter 219, and then the rolling cutter 219 processes it.

[0022] Example 3, as Figure 12 As shown, during gear machining, the eighth servo motor 43 drives the second rotating block 44 to rotate, and the deflection block 45 causes the rotating column 46 to swing, driving the brush head 47 to clean the surface of the cleaning device and ensure that the debris in the machining area is effectively removed. The rotor of the seventh servo motor 42 passes through the placement support plate 41 and is connected to the device base 1. The angle of the placement support plate 41 can be adjusted to prevent obstruction when changing the machining mode. The liquid pump 52 draws coolant from the liquid tank 51 and delivers it to the middle of the first clamping plate 323 and the second clamping plate 324 through the material conveying pipe 53, aligning it with the gear machining area. During the machining process, the coolant cools and lubricates the gear and the tool, reduces the deformation caused by cutting heat, improves machining accuracy, and extends the tool life.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
