[0031] Specifically, the drilling assembly includes a mounting seat 210 arranged on the rotating table 110 and a main shaft 220 that slides on the mounting seat 210 and can move along the length direction of the rotating table 110, one of the two opposite ends of the main shaft 220 is provided with a drill chuck 230 for clamping a drill rod 240, and the other end is connected to a drill gun, wherein the mounting seat 210 radially limits the radial direction of the main shaft 220 to ensure that there is no deviation or loosening during the drilling process, and the specific structure and working principle of the drill gun are all existing technologies and are not described in detail here; by starting the drill gun, the main shaft 220 is rotated to drive the drill rod 240 and the drill bit, and then the main shaft 220 is moved on the mounting seat 210, and the feed speed and depth of the drill bit are adjusted to achieve drilling processing.

[0032] Specifically, the fixing assembly includes two supporting members arranged opposite to each other on the workbench 120 and respectively located on both sides of the rotating table 110. The two supporting members are respectively used to fix the opposite ends of the crankshaft to ensure the stability and accuracy of the crankshaft during the drilling process.

[0033] In the embodiment of the utility model, the horizontal position of the rotating table 110 can be adjusted by the rotation setting of the rotating table 110 and the workbench 120, thereby driving the adjustment of the angle and position of the crankshaft on the fixed component, so that the drilling component of the rotating table 110 can adapt to the processing of inclined oil holes of various models of crankshafts, thereby reducing equipment costs and the space occupied by the equipment.

[0034] like Figure 1-4 As shown, in the embodiment of the utility model, each of the support members includes two first support blocks 310 arranged on the workbench 120, a fixed plate 330 arranged between the two first support blocks 310, a movable frame 340 sliding on the fixed plate 330, and two second support blocks 320 arranged on the movable frame 340, wherein the two first support blocks 310 and the two second support blocks 320 are staggered, and by adjusting the movable frame 340, the second support block 320 is moved and clamped with the first support block 310 to adapt to crankshafts of different sizes, and at the same time, the position of the crankshaft is also restricted to ensure sufficient stability and avoid displacement during drilling.
