Description

Technical Field

[0001] The invention relates to the technical field of gear turning equipment, and in particular to a PCD tool for gear turning. Background Art

[0002] PCD tools refer to polycrystalline diamond tools, which are mainly used to process materials with higher hardness, such as aluminum alloys, copper alloys, plastics and composite materials. PCD tools have excellent wear resistance and thermal conductivity, can provide longer service life and higher processing accuracy, and are widely used in mechanical processing, mold manufacturing and other fields. They are usually used in cutting, milling, drilling and other processes, suitable for high-efficiency and high-precision processing needs.

[0003] For example, a Chinese invention patent (CN108907367B) discloses a gear processing tool, which records: "When the processing tool needs to be disassembled, the two push rods are moved to the side close to each other, so that the bottom ends of the two U-shaped rods are respectively disengaged from the two second positioning grooves, so that the processing tool can be easily disassembled and replaced." It also records: "The device needs to be fastened by bolts after adjustment, which makes the adjustment work complicated and reduces work efficiency. At the same time, this device cannot easily adjust the position of the processing tool according to the processing of gears of different sizes. At the same time, the processing tool is not easy to disassemble and maintain, which makes it inconvenient to use. There is room for improvement." Technical problems.

[0004] To sum up the above, it can be known that in the prior art, two push rods are moved toward each other so that the bottom ends of the two U-shaped rods are respectively separated from the two second positioning grooves. However, this method has the following technical problems: however, the bottom ends of the two U-shaped rods are inserted into the corresponding two second positioning grooves, and during the cutting process, the contact area, angle and pressure between the tool and the gear cutting change, so that the cutting force generated by the interaction between the tool and the workpiece changes accordingly, and then the tool will vibrate to a certain extent.

[0032] Through the above structural design, when the installation shell 8, the rotating rod 9 and the tool body 10 are installed, the two sliding plates 26 are squeezed toward the middle, driving the clamping column 27 to leave the corresponding clamping hole 29. In this process, the second spring 28 is deformed, and then the rotating door 23 can be pulled, so that the rotating door 23 carries the second blocking mesh plate 24 and the corresponding ball 25 to rotate relative to the device housing 1. Then, the two sliding plates 26 are loosened, and the clamping column 27 can slide a certain distance inside the rotating door 23 under the action of the elastic force of the second spring 28, and then the outer wall of the rotating rod 9 is in contact with the ball 25 on the first blocking mesh plate 22, and the installation shell 8 is located in the device housing 1, and then the mounting shell 8 is inserted into the supporting shell 7, pushing the limiting tooth plate 12 to drive the four-sided platform 13 to move to the side close to the rotating rod 9, thereby causing the four rollers 16 to roll on the upper, lower, left and right surfaces of the four-sided platform 13, and thereby causing the first spring 18 to deform, so that the four upper, lower, left and right limiting rods 15 pass through the mounting shell 8 and are finally stably stuck in the supporting shell 7. During this process, the limiting claw 20 always maintains a tendency to be closely attached to the top of the limiting tooth plate 12 under the elastic force of the torsion spring 21, and after the limiting tooth plate 12 is pushed to a suitable position, the limiting claw 20 presses against the corresponding teeth on the limiting tooth plate 12 at this time, thereby 12 is limited in sliding inside the support shell 7, so that the limiting tooth plate 12 cannot slide in the direction away from the rotating rod 9, and then the two sliding plates 26 can be squeezed toward the middle, driving the clamping column 27 to be retracted into the rotating door 23, and the second spring 28 is deformed accordingly, and then the rotating door 23 is rotated, so that the ball 25 in the second blocking mesh plate 24 contacts the rotating rod 9, and then the two sliding plates 26 are released, so that the two clamping columns 27 can be inserted into the corresponding clamping holes 29 under the action of the corresponding second spring 28 elastic force, and the rotating door 23 is closed, and then the installation shell 8, the rotating rod 9 and the tool body 10 are installed.
