Abstract

The invention discloses a lathe fixture for fixing parts with irregular excircles, comprising a fixture seat including a connecting plate and a supporting plate which are fixedly connected with each other, and the angle of inclination of the supporting plate is consistent with that of the excircle of the part. The lathe fixture leads a lathe spindle to be coaxial with the excircle of the part by ensuring the angle of inclination of the supporting plate to be consistent with that of the excircle of the part, so that the excircles of the parts can be processed on the common horizontal type lathe. The lathe fixture has the advantages of simple structure, convenient operation, good interchangeability and reducing the processing cost of the parts.

Description

Be used for fixing turning attachment with irregular excircles part
Technical field
The present invention relates to a kind of turning attachment, relate in particular to a kind of turning attachment that is used for fixing with irregular excircles part.
Background technology
In the prior art, the out-of-shape of some parts is arranged, have the cylindrical of protrusion structure, and periphery and bottom surface (locating surface) formation space angle.For this part, with clamping, cause processing inconvenience with the machine tool difficult processing; The work in-process heart is processed has then increased manufacturing cost of parts.Therefore, provide a kind of and can become the technical problem of present stage urgent need solution so that have the turning attachment that the part of irregular excircles can be processed on common horizontal lathe.
Summary of the invention
The objective of the invention is at the unmanageable defective of the part that has irregular excircles in the prior art, a kind of turning attachment with irregular excircles part that is used for fixing that can process this part on common horizontal lathe is provided.
This is used for fixing the turning attachment with irregular excircles part and comprises clamping fixture seat, and described clamping fixture seat comprises fixedly connected connecting plate and gripper shoe, and described gripper shoe angle of inclination is consistent with described part cylindrical angle of inclination.
Turning attachment of the present invention is consistent with part cylindrical angle of inclination by the gripper shoe angle of inclination of clamping fixture seat, makes lathe spindle coaxial with the part cylindrical, so just can process the cylindrical of this part.Using turning attachment of the present invention, not only can be so that having the part of irregular excircles can process on common horizontal lathe, and this turning attachment is simple in structure, easy to operate, interchangeability is good, has also reduced the cost of part processing.
Description of drawings
Fig. 1 has the structure chart of the turning attachment of irregular excircles part for the present invention is used for fixing;
Fig. 2 is the structure chart of clamping fixture seat in the turning attachment of the present invention;
Fig. 3 is for fixedly having the schematic diagram of irregular excircles part in the turning attachment of the present invention.
Among the figure: the 1-clamping fixture seat; The 11-gripper shoe; The 12-connecting plate; The 13-reinforcement;
2-part to be processed; The 21-cylindrical; The 4-back-up block; The 5-alignment pin; The 6-clamping screw;
The 7-ring flange; The 8-balance weight; The 9-lathe spindle.
The specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2 and shown in Figure 3, in the embodiment of the invention, be used for fixing turning attachment and comprise that clamping fixture seat comprises fixedly connected connecting plate 12 and gripper shoe 11 with irregular excircles part, gripper shoe 11 angles of inclination are consistent with part cylindrical 21 angles of inclination.Gripper shoe 11 and connecting plate 12 are welded.In order to strengthen the intensity of clamping fixture seat 1, gripper shoe 11 all is welded with reinforcement 13 up and down, reinforcement 13 fixed support plates 11 and connecting plate 12.
This turning attachment also comprises positioner and clamping device, and positioner comprises some back-up blocks 4 and alignment pin 5, and back-up block 4 is fixed on the gripper shoe 11 by screw, alignment pin 5 and gripper shoe 11 interference fit.Support fast 4 and 6 frees degree of alignment pin 5 restriction part 2 to be processed, play the effect of locating element.Clamping device comprises clamping screw 6, and gripper shoe 11 is provided with the screw with clamping screw 6 correspondences.By screw rod 6 part 2 to be processed is clamped, be fixed on the gripper shoe 11.
This turning attachment also comprises jockey and bascule, and jockey comprises ring flange 7, and the one side of ring flange 7 is connected with lathe spindle 9 by chuck; The another side of ring flange 7 is fixedlyed connected with connecting plate 12.Bascule comprises at least one balance weight 8, is fixed on the ring flange 7 by screw.Can be by balance weight is set so that when processing was rotated, the barycenter of turning attachment was near the centre of gyration.Before processing, the position of adjusting the chuck four paws makes cylindrical 21 coaxial with lathe spindle 9.The afterbody of part cylindrical 21 withstands with lathe centre, prevents that turning from adding the man-hour part and flying out.
Because the locating surface of part 2 to be processed is angled with cylindrical 21 parts that need processing, need guarantee during turning that cylindrical 21 is coaxial with lathe spindle 9, so clamping fixture seat 1 must be the angle of inclination.Therefore, among the present invention, form clamping fixture seat with gripper shoe 11 and connecting plate 12 welding, gripper shoe 11 angles of inclination are identical with the angle of inclination of part cylindrical 21, make lathe spindle 9 also coaxial by adjusting chuck, so just can process the cylindrical of this part with part cylindrical 21.
The present invention is used for fixing the turning attachment with irregular excircles part simple in structure, in light weight, easy to operate advantage, and can reduce the part processing cost, exchanges on general horizontal lathe and uses.
It should be noted that at last: above embodiment only in order to the explanation the present invention and and unrestricted technical scheme described in the invention; Therefore, although this specification has been described in detail the present invention with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the invention, and it all should be encompassed in the claim scope of the present invention.
