The utility model discloses a crankshaft supporting structure for crankshaft machining, which comprises a mounting plate arranged on a machine tool, wherein a supporting stud is connected onto the mounting plate, an insert block is connected to the top of the supporting stud, a supporting tube is sleeved on the insert block, a nut is screwed on the supporting stud, at least two supporting frames are arranged on the supporting tube, one of the supporting frames is connected onto the supporting tube, a high-speed bearing is rotatably arranged in the supporting frame, a mounting opening is formed in the side of the supporting frame, and a quick-release rod is arranged in the mounting opening. The high-speed bearing outer lane below supports the limit axle of pressing contact bent axle, and when the depression bar of quick detach pole was compressed tightly, the outer lane of high-speed bearing supported pressing contact on the limit axle of bent axle, consequently when the rotatory in-process of bent axle, can effectively support the limit axle of bent axle, reduced the limit axle and received downward impact force, solved the limit axle and received the great problem of downward impact force.

Description

Crankshaft supporting structure for crankshaft machining

Technical Field

The utility model belongs to the technical field of crankshaft machining, and particularly relates to a crankshaft supporting structure for crankshaft machining.

Background

During the crankshaft turning, because the rotatory in-process of bent axle, certain unbalanced centrifugal force has, the lathe tool of different positions in addition to its turning extrusion force, its fixed position is rotatory to be used two triangle chuck lathe usually to realize, through the clamp of triangle chuck to the bent axle both sides, can avoid the skew rotation center of bent axle, the weak point of existence is: when the crankshaft is high in rigidity and the crankshaft part is heavy, in the process of downward cutting of the turning tool, the side shafts on two sides of the crankshaft are subjected to large downward impact force, and the stability of the crankshaft clamped on the triangular chuck is affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a crankshaft supporting structure for crankshaft machining, which aims to solve the problem that an edge shaft in the prior art is subjected to large downward impact force.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a bent axle bearing structure for bent axle processing, is including installing the mounting panel on the lathe, be connected with the support double-screw bolt on the mounting panel, the top of support double-screw bolt is connected with and is equipped with the stay tube on inserted block and the inserted block, the spiro union has the nut on the support double-screw bolt, be provided with two at least support frames and one of them support frame on the stay tube and connect on the stay tube, the support frame internal rotation is provided with high speed bearing, the avris of support frame is equipped with and is provided with the quick detach pole in installing port and the installing port.

Preferably, the insert block is of a square block structure, and the support tube is of a cylindrical structure with a square through hole in the center.

Preferably, the support frame is a U-shaped plate structure with square pieces arranged on two sides.

Preferably, a connecting shaft is arranged in the support frame and is inserted into an inner ring of the high-speed bearing in a penetrating manner.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the outer ring of the high-speed bearing below is pressed against and contacted with the side shaft of the crankshaft, and when the pressure rod of the quick-release rod is pressed, the outer ring of the high-speed bearing is pressed against and contacted with the side shaft of the crankshaft, so that the side shaft of the crankshaft can be effectively supported in the rotation process of the crankshaft, the downward impact force applied to the side shaft is reduced, and the problem that the side shaft is subjected to a large downward impact force is solved.

FIG. 1 is a schematic front view of the present invention;

FIG. 2 is a schematic view in partial cutaway of FIG. 1;

FIG. 3 is a schematic view of the connection of the support tube of the present invention;

fig. 4 is an enlarged schematic view of a portion of fig. 2.

In the figure: the quick-release device comprises a mounting plate 1, a support stud 2, an insertion block 3, a support tube 4, a nut 5, a support frame 6, a connecting shaft 7, a high-speed bearing 8, a mounting opening 9 and a quick-release rod 10.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Fig. 1, fig. 2, fig. 3 and fig. 4, a bent axle bearing structure for bent axle processing, fix mounting panel 1 on the lathe mesa including the bolt, the central point of mounting panel 1 puts the welding and has support stud 2, the top welding of support stud 2 has inserted block 3, inserted block 3 is square block structure, sliding sleeve is equipped with stay tube 4 on the inserted block 3, inserted block 3 is square block structure, stay tube 4 sets up square hole's cylinder structure for the center, stay tube 4 can not rotate on inserted block 3, the spiro union has nut 5 on the support stud 2, support stud 2 through nut 5 supports, restriction stay tube 4 moves down on inserted block 3, the bottom welding of the support frame 6 that is provided with two support frames 6 and below position on stay tube 4 is in the upper end of stay tube 4, support frame 6 sets up the U template structure of square piece for both sides around.

Fig. 1, fig. 2, fig. 3 and fig. 4, it alternates at high speed bearing 8's inner circle to weld connecting axle 7 and connecting axle 7 interference in support frame 6, the rotation of support frame 6 is provided with high speed bearing 8, the avris of support frame 6 is equipped with installing port 9 and is provided with quick detach pole 10 in the installing port 9, when the depression bar of quick detach pole 10 was compressed tightly, high speed bearing 8's outer lane was supported the press contact on the limit of bent axle, through high speed bearing 8's outer lane, the limit axle of accepting the bent axle rotates, the reduction friction loss.

The working principle of the embodiment is as follows: during the use, dismantle support frame 6 from below with above-mentioned support frame 6, install the bent axle on the triangle chuck of both sides earlier, swivel nut 5 is followed, nut 5 upwards rotatory removal on supporting stud 2, stay tube 4 is upwards passed, the limit axle of high-speed bearing outer lane support pressing contact bent axle down, 6 covers support frame 6 below with another support frame, and align installing port 9, and penetrate quick detach pole 10 in installing port 9, when the depression bar of quick detach pole 10 is compressed tightly, the outer lane of high-speed bearing 8 supports pressing contact on the limit axle of bent axle, consequently, when the rotatory in-process of bent axle, can effectively support the limit axle of bent axle, it receives down impact force to reduce the limit axle.

The outer ring of the high-speed bearing 8 is used for bearing the rotation of the side shaft of the crankshaft, so that the friction loss is reduced.
