A precision gear processing cutting machine tool with automatic tool setting

Abstract

The present invention discloses a cutting machine tool for precision gear processing with automatic tool setting, which includes a cutting table. Inside the placing frame arranged in the middle of the cutting table, there is a placing and fixing component. In the middle of the top of the installation frame arranged at the upper end of the cutting table, there is a bidirectional motor, and one output end of the bidirectional motor is connected to a cutting component. When the output end arranged on one side of the bidirectional motor drives the cutting component to rise, the output end transmission component arranged on the other side of the bidirectional motor drives the placing and fixing component to rotate, so as to replace the cutting position of the workpiece body. On the contrary, when the output end arranged on one side of the bidirectional motor drives the cutting component to descend, the output end arranged on the other side of the bidirectional motor stops working, so that the cutting component cuts the workpiece body. The rotation angle of the workpiece body is detected by an automatic angle measuring instrument, so that the rotation angle matches the cutting processing speed, thereby improving the processing efficiency.

At the same time, the front of the installation side plate 19 is connected to one end of the center punch 17 through a universal joint 18. The other end of the center punch 17 is located outside the cutting position of the workpiece body 206 and the cutting tool 1601, and the position of the center punch 17 is on the same horizontal plane as the position of the workpiece body 206. The accuracy of the cutting position is further improved through the center punch 17, and the top of the lifting top plate 1603 is rotationally connected to the side column 1608 arranged on one side of the eccentric turntable 1609 through a lifting adjustment assembly.

[0035] Specifically, the lifting adjustment assembly includes a connecting rod 1605, a limiting sleeve 1606 and a transmission rod 1607. The lower end of the connecting rod 1605 is connected to the middle of the upper end of the lifting top plate 1603.

The top of the universal connecting piece 16071 is connected to the lower end of the transmission rod 1607. The top of the transmission rod 1607 passes through the upper end of the limiting sleeve 1606 and is connected to the side column 1608. At the same time, the limiting sleeve 1606 is connected to the inside of one side of the top of the installation frame 13.

[0036] During use, the bidirectional motor 15 drives the eccentric turntable 1609 to rotate. Then, the side column 1608 provided on the eccentric turntable 1609 rotates synchronously. Next, while the lower end of the transmission rod 1607 connected to the side column 1608 rotates inside the upper end of the limit sleeve 1606 through the universal joint 16071, it pushes the connecting rod 1605 to move downward inside the limit sleeve 1606, causing the connecting rod 1605 to push the two sides of the lifting top plate 1603 to move downward on the corresponding moving guide rails 1604. Then, the cutting tool 1601 connected to the lower end of the lifting top plate 1603 through the threaded column 1602 moves downward to perform cutting on the workpiece body 206.
