Description

Technical Field

[0001] The utility model relates to the technical field of boring processing equipment, in particular to a plane boring and milling cutter disc, in particular to a boring processing cutter disc used for the plane of large-scale working condition spare parts. Background Art

[0002] The boring processing of the plane of large spare parts, especially the plane processing of special-shaped structural parts, is generally carried out on a horizontal boring machine. The general processing method is to use the tool bar to clamp the boring tool for processing. The maximum rotation radius is achieved by rotating the position of the plane disk on the spindle to achieve the boring processing of the large plane. The plane exceeding the rotation radius needs to move the workpiece twice to complete the boring of the entire plane. This processing method has certain limitations. First, the rotation radius of the plane disk is limited, and the maximum processing range of the spindle is limited, so the product processing selectivity is limited. Secondly, in order to meet the boring of the entire plane of large products, only the position of the workpiece is moved twice, which will cause errors caused by tool connection and secondary reference alignment, affecting the flatness of the entire plane. At the same time, the tool bar can only clamp one boring tool at a time to complete the boring of the plane. Within a certain operating time, the operator needs to move the workpiece many times for alignment when processing a large plane, which is labor-intensive and inefficient. Utility Model Content

[0025] The use principle of the utility model is that the utility model is assembled with a cutter disc body and four tool platforms, which are installed on a boring and milling machine. The main shaft drives the cutter disc to rotate, and the overall boring of a large plane is realized through the feeding of the worktable. A forged part is selected as the cutter disc body. A 3mm thick thin copper plate is used between the cutter platform and the cutter disc body for fixing through countersunk screws. The metal ductility of the copper plate is used to reduce the rigid friction between the cutter disc body and the cutter platform. A pin is designed on the cutter platform to adjust the clamping of the tool for easy operation and convenient disassembly and assembly. The whole machine is divided into four parts. The main shaft is used to drive the cutter disc body to rotate, thereby driving the four tool platforms to do circular motion. The screw rod is used to adjust the cutter platform scale dial, so that four tools can complete the processing of the same plane at the same time, achieving the boring function. At the same time, the pin principle is used to realize the fixation of the cutter platform and the cutter disc body through the clamping bolt and the thin copper plate, complete the connection of the four tools with the cutter platform, and perform boring work at the same time. The adjustment of the cutter platform scale dial can be realized by adjusting the screw rod and the nut, and the application range is wide.

[0026] Specifically, the tool table 3 is fixed to the cutter disc body 4 using a copper plate 6, a pin iron 9 and a cross recessed countersunk screw 8, and the tool table 3 and the tool holder body 4 are adjusted using an M10 bolt 5 to meet the needs of different installation positions. Through the installation cooperation relationship between the boring and milling machine and the tool table body 4, the spindle rotation drives the tool table body 4 to rotate, and the tool table body 4 drives the tool table 3 to make a circular motion, thereby realizing the rotation of the boring and milling cutter disc.

[0027] The clamping bolt 7 cooperates with the dovetail structure of the tool table 3 to achieve the installation and fixation of the tool and the tool table 3. The main shaft drives the tool table body 4 to rotate, and then the tool table body 4 drives the tool table 3 to rotate, thereby driving the tool fixed on the tool table 3 by the clamping bolt 7 to rotate. The position movement of the workpiece is completed by the longitudinal and lateral movement of the worktable of the boring and milling machine equipment, and the boring function of the boring and milling cutter on the large plane of the working spare part is realized.

[0028] A dial 13 is installed on the tool stage 3, and the dial 13 is installed on the screw rod 10 through the semicircular key 12. The screw rod 10 passes through the inner hole of the copper sleeve 14 and is installed and matched with the tool stage 3. The screw rod end of the screw rod 10 is installed on the tool stage 3 through threaded cooperation with the nut 15. The position of the dial 13 is adjusted by adjusting the threaded cooperation distance between the screw rod 10 and the nut 15 to determine different cutting depths. Then, the dial 13 is adjusted to a suitable position using the small round nut 11 and then fixed. The tool stage body 4 rotates to drive the tool to rotate, thereby realizing boring processing with different cutting depths.
