Detailed Description

For a better understanding of the nature of the utility model, its description is further set forth below in connection with the specific embodiments and the drawings.

The utility model is suitable for machining inner holes in two sides of a workpiece, and particularly relates to a through hole machining lathe. The lathe can adopt a common 50 lathe in a workshop, in particular to a CW61100 lathe, as shown in figures 1 to 4, and comprises a main spindle box 1, wherein a main spindle is arranged in the main spindle box 1; the main shaft is detachably connected with the flange plate 2, and the flange plate 2 is detachably connected with the cutter bar 3. The cutter bar 3 is detachably connected with the cutter 5. Preferably, the flange 2 is provided with mounting holes 201 and positioning holes 202. The mounting holes 201 are used for being matched with bolts to connect the flange 2 with the main shaft and the cutter bar 3. The mounting holes 201 are provided with 8, four of which are connected with the main shaft and the other four of which are connected with the cutter bar 3. The positioning hole 202 is located at the center of the flange 2, and the positioning hole 202 is a through hole and used for positioning the center of the cutter bar 3. The high-speed rotating center 7 is arranged at the position corresponding to the tail of the cutter bar 3, and the high-speed rotating center 7 is used for positioning the center of the cutter bar, so that the cutter bar is prevented from vibrating during machining and bearing the cutting force of a cutter, and the machining precision of an inner hole is further ensured.

As shown in fig. 5 to 7, the lathe for processing a through hole according to the present invention further includes a vertical plate 4 and a table 6. The vertical plate 4 is connected to a lathe sliding plate through a bolt, and the workbench 6 is connected with the vertical plate 4 through a bolt. A workpiece to be processed is placed on the workbench 6, and the processed workpiece can be fixed through the pressing plate 8 in cooperation with the bolt. The worktable 6 is provided with a first waist hole 601 and a first threaded hole 602, and the pressing plate 8 is provided with a second waist hole 801 and a second threaded hole 802.
