[0048] Among them, the crankshaft on the first processing unit A can be transferred to the clamping mechanism 3 of the second processing unit B by artificial; preferably, the transfer is carried out by automatic machinery, and reference is made to Figures 13-15A transfer device 7 for moving the crankshaft on the first machining unit A to the second machining unit B can be arranged above the base 2, the transfer device 7 comprising a mechanical hand 71 movable along a first direction X, the mechanical hand 71 being liftable and lowerable.

In other words, when the plurality of petal-shaped clamping plates 451 are close to the axial center thereof, the diameter of the clamping hole 452 becomes smaller, so that the drill bit 44 is clamped. In addition, the clamping principle of the clamping cylinder 45 and the limiting ring 46 can refer to the precision membrane petal type inner expansion and outer clamping spindle chuck with publication number CN207387167U.

In this way, the first driving motor 43 is directly connected with two lock cutter spindles 42 through a synchronous belt, and the two lock cutter spindles 42 can drive the remaining lock cutter spindles 42 to rotate.

[0052] The above scheme is specific, referring to Figure 8, the milling groove mechanism 5 comprises a second mounting table 51 arranged on the moving table 61, a rotating shaft 52 rotatably arranged on the second mounting table 51, and a second driving motor 54 for driving the rotating shaft 52 to rotate; a plurality of circular milling cutters 53 are coaxially arranged on the rotating shaft 52.

[0053] In some specific embodiments, in order to facilitate the clamping of the crankshaft, referring to Figures 9-12 , the clamping mechanism 3 comprises a base 31, the base 31 is provided with a limiting groove 311, the groove bottom of the limiting groove 311 is provided with an inverted T-shaped groove 312; a plurality of bearing tables 32 are slidably arranged in the limiting groove 311, the top of the bearing table 32 is provided with a V-shaped groove 321 for supporting the shaft body 200 of the crankshaft; the bearing table 32 is provided with a vertical lock hole 322, a locking bolt 323 is inserted into the lock hole 322 from top to bottom, the bottom end of the locking bolt 323 is threadedly connected with a T-shaped clamping block 324, and the T-shaped clamping block 324 is located in the inverted T-shaped groove 312; the eccentric block 300 of the crankshaft abuts against the side surface of one of the bearing tables 32; the base 31 is provided with an end abutting block 33, the end abutting block 33 is provided with an avoiding groove 331 for the drill bit 44 and the milling cutter to pass through; the end of the crankshaft abuts against the side surface of the end abutting block 33; the base 31 is provided with a pressing mechanism 34, and the pressing mechanism 34 comprises a pressing block 343 for pressing the crankshaft on the bearing table 32. In actual application, the shaft body 200 of the crankshaft is arranged on the V-shaped groove 321 of the bearing table 32, since there are a plurality of bearing tables 32, the crankshaft can be stably supported to prevent the crankshaft from moving in the horizontal direction along the radial direction; in addition, the side surface of the eccentric block 300 on the crankshaft abuts against the side surface of the bearing table 32, and the other end of the crankshaft abuts against the end abutting block 33, the bearing table 32 and the end abutting block 33 clamp and limit the crankshaft to prevent the crankshaft from moving in the horizontal direction along the axial direction; finally, the crankshaft is pressed on the bearing table 32 by the pressing mechanism 34 to prevent the crankshaft from moving in the vertical direction, thereby realizing the stable clamping of the crankshaft. The drill bit 44 on the drilling mechanism 4 and the center milling cutter on the milling groove mechanism 5 pass through the avoiding groove 331, thereby processing the end of the crankshaft, and the avoiding groove 331 avoids interference.

[0054] In addition, when the locking bolt 323 rotates in the locking hole 322, the height position of the locking bolt 323 is unchanged, and the locking bolt 323 drives the T-shaped clamping block 324 to move upward, so that the T-shaped clamping block 324 and the nut of the locking bolt 323 clamp the bearing platform 32 in the limiting groove 311, and finally realize the fixation of the bearing platform 32 in the limiting groove 311. By adjusting the position of the bearing platform 32 in the limiting groove 311, the crankshaft of different sizes can be adapted.

[0055] To further improve the stability of the crankshaft during clamping, with reference to Figure 10 and Figure 12 , the adjusting seat 35 is slidably arranged in the limiting groove 311, the first matching surface 351 is arranged on the adjusting seat 35, the supporting table 36 for supporting the eccentric block 300 on the crankshaft is arranged on the adjusting seat 35, the second matching surface 361 is arranged on the bottom of the supporting table 36, and the second matching surface 361 is slidably abutted on the first matching surface 351; the first slot hole 362 is vertically arranged on the supporting table 36, the first threaded hole 352 is vertically arranged on the first matching surface 351, the first adjusting bolt 363 is arranged in the first slot hole 362, and the end of the first adjusting bolt 363 is threadedly connected with the first threaded hole 352; wherein the eccentric block 300 on the crankshaft is supported by the supporting table 36; when different sizes of eccentric blocks 300 need to be adapted, the first adjusting bolt 363 can be loosened, so that the supporting table 36 can move along the first matching surface 351, thereby changing the height of the top of the supporting table 36; in the above process, the position of the first adjusting bolt 363 in the first slot hole 362 changes; after the first adjusting bolt 363 is tightened again, the nut of the first adjusting bolt 363 presses the supporting table 36 on the adjusting seat 35, and the fixation of the supporting table 36 is realized.

[0056] In addition, to strengthen the stability of the supporting table 36 on the adjusting seat 35, with reference to Figure 12The adjusting seat 35 is provided with a vertical side plate 353 on the adjusting seat 35, and the side plate 353 is located at one end of the first fitting surface 351 which is higher.

In other words, the support table 36 is fixed by the side plate 353 and the second adjusting bolt 355. When the height of the support table 36 needs to be adjusted, the second adjusting bolt 355 needs to be loosened in addition to the first adjusting bolt 363. In this way, even if the first adjusting bolt 363 is loosened during the machining process, the second adjusting bolt 355 can ensure that the height position of the support table 36 does not decrease, thereby maintaining the support of the eccentric block 300.

[0057] To further strengthen the limiting of the support table 32 to the crankshaft, the following is specifically provided.

The support table 32 is provided with a third threaded hole 327, and the third slot hole 326 is provided with a third adjusting bolt 328, and the end of the third adjusting bolt 328 is threadedly connected with the third threaded hole 327. In this way, the distance between the clamping blocks 325 can be adjusted to adapt to crankshafts of different sizes and to a certain extent to clamp and limit the shaft body 200 of the crankshaft. In addition, the position of the adjusting seat 35 in the limiting slot 311 can be adjusted, and the adjusting mode of the adjusting seat 35 in the limiting slot 311 can be the same as the adjusting mode of the support table 32.

[0058] The following is specifically provided with reference to Figure 9 and Figure 10 In this embodiment, the base 31 is provided with two limiting slots 311, and each limiting slot 311 corresponds to clamping a crankshaft.

When the crankshaft does not need to be fixed, the rotary telescopic cylinder 341 can move the connecting piece 342 and the pressing block 343 to one side of the crankshaft, so as to avoid blocking the crankshaft from being taken out and avoiding interference with the mechanical hand taking out the crankshaft.

[0059] In some specific embodiments, to facilitate the collection of the debris generated by machining the two ends of the crankshaft, reference is made to Figure 2 and Figure 3 The base 2 is provided with two inclined flow channels 21, which are respectively located on the two sides of the clamping mechanism 3.
