Description
Technical field
The invention belongs to Machining Technology, relate to the improvement to slender axles Excircle machining fixture.
Background technology
Being referred to as slender axles when the length-to-diameter of industry upper shaft is more than 25, slender axles are adding man-hour by rigidity deficiency
Impact, is very easy to deform when turning and grinding are with top holding out against, cause the excircle dimension of processing rear axle and cylindricity,
Roughness all can not meet processing request, can cause waste product time serious.
Summary of the invention
The purpose of the present invention: propose a kind of fixture for slender axles Excircle machining, to meet slender axles Excircle machining
Requirement.
Technical scheme: a kind of fixture for slender axles Excircle machining, including: main shaft (1), gland (2), axle
Bearing (3), radial ball bearing (4), thrust ball bearing (5), housing screw (6), main shaft leading portion is shaped with external screw thread (1a), main shaft
(1) front end center is shaped with blind hole (1b), and the external diameter in the stage casing (1c) of main shaft (1) is more than external screw thread (1b) maximum gauge, main shaft
(1) rear is the shaft shoulder (1d), and the external diameter of the shaft shoulder (1d) is more than the external diameter in stage casing (1c)；The center of gland (2) is through hole (2a), pressure
One end of set (2) is shaped with screw thread platform hole (2b), and gland (2) is connected with the external screw thread (1b) of main shaft (1) by screw thread platform hole (2b)；
Bearing block (3) is cover parts, and the left end of bearing block (3) is shaped with shoulder (3a), and there is circular hole at the right-hand member center of bearing block (3)
(3c), it is shaped with screwed hole (3b) in bearing block (3) right-hand member radial direction；Thrust ball bearing (4) and radial ball bearing (5) overlap successively
Stage casing (1c) in main shaft (1) is upper and contacts with the shaft shoulder (1d), and the circular hole (3c) of bearing block (3) is sequentially sleeved in thrust ball bearing
(4), on cylindrical (4a), radial ball bearing (5) cylindrical (5a), bearing block (3) is contacted with radial ball bearing (4) by shoulder (3a),
Housing screw (6) is arranged in bearing block (3) screw hole (3b).
Advantages of the present invention
By the pulling function of present clip, the rigidity of slender axles is made to be improved, owing to installing bearing in clamp body,
So workpiece rotates flexibly in the course of processing, there is again the pulling function of tailstock tool, therefore can bear bigger axial force, energy
Slender axles workpiece being effectively ensured will not bend in grinding process after cutting, this fixture manufactures simplicity, easy to use, practical function
Very well.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention:
Below the present invention is described in further details.See Fig. 1, a kind of fixture for slender axles Excircle machining, it
Main shaft 1, gland 2, bearing block 3, radial ball bearing 4, thrust ball bearing 5, housing screw 6 form, and main shaft leading portion is shaped with external screw thread
1a, the front end center of main shaft 1 is shaped with blind hole 1b, and the external diameter of the stage casing 1c of main shaft 1 is more than external screw thread 1b maximum gauge, main shaft 1 tail
Section is shaft shoulder 1d, the external diameter of the shaft shoulder 1d external diameter more than stage casing 1c；The center of gland 2 is through hole 2a, and one end of gland 2 is shaped with spiral shell
Stricture of vagina platform hole 2b, gland 2 is connected with the external screw thread 1b of main shaft 1 by screw thread platform hole 2b；Bearing block 3 is cover parts, bearing block 3
Left end is shaped with shoulder 3a, and there is circular hole 3c at the right-hand member center of bearing block 3, is shaped with screwed hole 3b in bearing block 3 right-hand member radial direction；Push away
Power ball bearing 4 and radial ball bearing 5 are sequentially sleeved on the stage casing 1c of main shaft 1 and contact with shaft shoulder 1d, the circular hole 3c of bearing block 3
Being sequentially sleeved on thrust ball bearing 4 cylindrical 4a, radial ball bearing 5 cylindrical 5a, bearing block 3 is by shoulder 3a and radial ball bearing 4
Contact, housing screw 6 is arranged in bearing block 3 screw hole 3b.
The using method of the present invention is: the tail end at slender axles 8 processes shaft shoulder 8a and positioning section 8b, by the circular hole of main shaft 1
1c joins car by the positioning section 8b of slender axles 8 and is slidably matched, then by main shaft 1 and bearing block 3, radial ball bearing 4, thrust ball bearing 5
Installing, fixed with tailstock tool 7 by housing screw 6, then the positioning section 8b by slender axles 8 is inserted into the circle of main shaft 1
In the 1c of hole, by gland 2, the shaft shoulder 8a of slender axles 8 is pressed on main shaft 1.
The present invention is fixed with tailstock tool by bearing block, slender axles plays axis fixation, does not the most affect elongated
The rotation of axle, thus it is effectively increased the non-deformability of slender axles, improve machining accuracy.
