TECHNICAL FIELD The present invention relates to a deburring device for screws, and more particularly to a device for deburring a screw provided in the middle of a shaft. <Prior Art> Conventional deburring of a screw of a shaft is performed, for example, as shown in FIG. 8, a die unit in which a holder 4 having a die blade 3 is attached to the inner circumference of a ring-shaped die body 2 having handles 1 on both sides. No. 5 is used and is manually performed. Due to the structure of the die unit 5, deburring is very difficult except when the screw n is near the end of the shaft s. When the screw n is in the middle of the shaft. It took a lot of time to work, because it was done manually. However, the one that can be applied to the one in which the screw is located in the middle of the shaft is a regular hexagonal shape having a diameter larger than the diameter of the screw diameter, such as the screw shaving jig of the large diameter screw shaft disclosed in Japanese Utility Model Publication No. 57-153427. A centering guide is provided at the center of the frame on the other side of the frame, and a pitch aligning guide for screw wiping is provided on any other two opposing sides. There is one that is installed so that it can be pulled out toward and away, and a screw wiping tool is attached to the center of the remaining one side, and the frame is rotated to clean it with a cutting tool. <Problems to be Solved by the Invention> In the jig disclosed in the above-mentioned Japanese Utility Model Publication, the screw portion can be precisely finished by removing the burrs by exposing the screw, but the regular hexagonal frame body is attached to the screw shaft one by one. It is necessary to fit it, and it is necessary to perform centering with the centering guide and to adjust the pitch with the pitch aligning guide for screw wiping.
Since the screws are used to remove the screws from the book, this also takes a lot of time and labor, and there is a drawback that the work efficiency is low. For the centering (centering),
As shown in Japanese Patent No. 104808, at least one part of a device main body attached to a main shaft of a machine tool and a cutting tool holding device such as a tap or a reamer has a shaft-shaped portion and a tubular portion which are fitted to each other with a certain clearance. And a plurality of circumferential grooves are engraved on the outer peripheral surface of the shaft-shaped portion or the inner peripheral surface of the tubular portion, and each groove is substantially aligned with the shaft center of the fitting portion. There is a technique in which a ring-shaped elastic member that is elastically deformable in a perpendicular direction is fitted so that the shaft portion is generally positioned and held concentrically with the tubular portion. Although it can be applied to aligning the drive shaft side with a support portion such as a tap or reamer that is rotated by the drive shaft side, it cannot be applied to aligning the rotating shaft and a die surrounding and fixing the shaft. In view of the above, the present invention is to provide a deburring device that can easily deburr a screw formed in the middle of a shaft, can easily perform centering, and can adjust a pressure applied to the screw. . <Means for Solving the Problem> The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 7 corresponding to the embodiments. The present invention is a work in which screws N 1 and N 2 are formed. A supporting and rotating mechanism 6 of S, a split die 20 having a blade portion 21 matching the pitch of the screws N 1 and N 2 , a die holding member 30 having a lateral movement mechanism 43 of the die 20, and the holding A support member 50 that supports the member 30 by a support shaft 44 so that the member 30 can swing in a direction perpendicular to the work, and a pressing spring mechanism that is arranged between the support member 50 and the holding member 30 so as to adjust the pressure.
53 to 55, and a moving mechanism 60 for moving the support member 50 with respect to the screws N 1 and N 2 of the work S. <Action> Work piece (shaft) with burrs formed with screws N 1 and N 2.
Both ends of S are supported by the support rotation mechanism 6 , the shaft S is rotated at a low speed by the drive mechanism 11 described later, and the support member 50 is brought closer to the screws N 1 and N 2 by the moving mechanism 60 , and the pressing spring mechanism 53 if the split die 20 via the holding member 30 by 55 brought into pressing contact with the screw N 1, N 2, the holding member 30 is a support shaft 4
While swinging around 4, the split die 20 is automatically aligned with the shaft S, the blade portion 21 of the die 20 meshes with the screws N 1 and N 2, and the die 20 moves as the shaft S rotates. Moving to the left (right), deburring of screws N 1 and N 2 is performed. <Working Example> A work S to which the deburring apparatus of the present invention is applied is a shaft as shown in FIGS. 6 and 7, for example, a main shaft of an automobile transmission, and clutch hub tightening screws N 1 and N 2.
Since There are formed splines L and keyway (not shown) is formed by broaching, after turning off the screw N 1, N 2, in the spline L and keyway in the screw N 1, N 2 A burr is generated in the portion along the line, and if the burr is left as it is, it will hinder the screw connection between the screws N 1 and N 2 and the nut. Further, when the spline L is formed by the broaching process, the ridges of the cut screws N 1 and N 2 may fall down, which also causes a difficulty in coupling with the nut. Embodiment shown in FIG. 1 is an example of a deburring device suitable to the work S, such as the main shaft in which a plurality of screws N 1, N 2 is formed, the workpiece supporting and rotating mechanism 6 bed 7

In this example, the split die 20 is a half die 21 obtained by dividing the known circular die 5 shown in FIG. 8 in half, and 22 is formed between the blade portions and 23 is formed between the blade portions 21. It is a chip escape groove. As is well known, the die has an inner diameter (blade 21
Since the outer diameters of the dies for the screws N 1 and N 2 are the same even if the inner diameters of the dies are different, the same holding block 35 can be used. Further, the split die 20 is not limited to half and may be divided into 1/3 and 1/4 depending on the degree of burr. The holding member 30 has a hole 31 through which a support shaft 44 described later passes.

The return spring 41 is fitted to the bar 40 and interposed between the holding block 35 and one die holding frame 33. Incidentally, 42 is a mounting screw for the die pressing L-shaped plate 37,
Further, among the members constituting the holding member 30 , a guide plate 34,
The slider 36, the guide bar 40, and the compression spring 41 constitute a lateral movement mechanism 43 of the die. The support member 50 is composed of a support arm main body 51 having a forked portion 51a into which the projection 31a of the die holding plate 31 can be inserted, and a support column 52 that supports the main body 51. The support column 52 is a table forming a part of the moving mechanism 60 described later.
It is attached to 63. The protrusion 51a is provided with a through hole 51b having an inner diameter slightly larger than the through hole 31b formed in the protrusion 31a of the die holding plate 31, and when the holding plate 31 is assembled, the through hole 31b and Circumferential groove 44a with approximately the same outer diameter and near both ends

And after inserting into the through hole 31b of the die holding plate 31, the center of the support shaft 44 is fixed to the die holding plate 31 with a screw 45, and the O-ring 46 is inserted between the through hole 51b and the support shaft 44. It is fitted in the circumferential groove 44a. This said die holding member 30 by becomes swingable about the shaft 44, and the O-ring 46 is floatingly supporting the die holding member 30 relative to the support member 50, the work split die 20 described later as When engaged with the screws N 1 and N 2 of S, the die 20 and the screws N 1 and N 2 are self-aligned to enable smooth and accurate deburring. Reference numeral 47 is an L-shaped stopper that regulates the swing range of the die holding member 30 , and is fixed to the support arm main body 51 at the lower end position of the die holding plate 31 with a machine screw 48 as shown in FIG. 53 is a pressure regulator of a pressing spring 55 that presses the die holding member 30 toward the work S side, and the main body 53a thereof is the support arm main body 51.
Of the pressing spring 55, which is attached to the rear surface of the support column 52 side, and which pushes the die holding plate 31 through the support arm main body 51 by the adjusting bolt 54. The spring 55, the adjusting bolt 54, and the pressure regulator 53 are called a pressing spring mechanism. The moving mechanism 60 is a table on which the supporting member 50 is fixed.
63, 63 'through the sliders 61, 61' through the guide rails 62,
A rod of a pneumatic (or hydraulic) cylinder (not shown) set on the bed 7 slidably mounted on the bed 62 'is connected to the support column 52 or the support arm main body 51. When deburring the screws N 1 and N 2 of the work S by the deburring apparatus of the present invention configured as described above, first , a half die which matches the diameters and screw pitches of the screws N 1 and N 2 respectively. 21 is selected and fitted in the groove 35a of the holding block 35, and the upper and lower sides are pressed and fixed by the die pressing L-shaped plate 37 and the side surface, respectively, and pressed by the adjusting bolt 54 of the spring pressure regulator 53 in advance. The initial setting pressure of the spring 55 is adjusted so that deburring of the screws N 1 and N 2 can be performed accurately and smoothly. The work S is held between the driving center 12 and the dead center 13 while adjusting the distance between them, and the motor 15 is rotated to rotate the work S at a low speed by the driving center 12 via the drive mechanism 11. Here, if the pneumatic cylinder of the moving mechanism 60 is operated and the support column 52 or the like is pushed by the rod, the half die 21 held by the die holding member 30 is pressed against the screws N 1 , N 2 of the work S. . Therefore, the holding member 30
Is pressed by the pressing spring 55, and the die holding plate 31 swings around the support shaft 44 within the range permitted by the stopper 47 to halve the die.
21 and the screws N 1 and N 2 of the work S are automatically aligned, and the blade portion 22 of the half die 21 meshes with the screws N 1 and N 2 . As a result, the holding block 35 having the half dies 21 meshing with the screws N 1 and N 2 moves to the right in FIG. 2 (a) and FIG. 3 while compressing the return spring 41 on the guide plate 34 by the slider 36. Then, deburring of the entire screws N 1 and N 2 is completed. When this completion is taken as a signal and the pneumatic cylinder is operated in reverse, the support column 52 and the like are pulled by the rod, and the half die 21 is pulled from the screws N 1 , N 2 of the work S via the holding member 30. Pull away. This causes the holding block 35 to move to the first position by the return spring 41.
Return to the position shown in FIG. 2 (a), FIG. 2 (a) and FIG. The work S can be removed by stopping the rotation of the driving center 12 and pulling the rotation receiving base 14 to the right in FIG. 1, for example. <Effects of the Invention> Since the present invention is configured as described above, in particular, a split die having a blade portion matching the pitch of a screw and a die holding member having a lateral movement mechanism of the die are provided. By this, deburring can be easily performed on the screw formed in the middle of the work (shaft), the work efficiency of deburring can be improved, and the split die and the holding member of the die are supported by the work shaft. By providing a support member that swingably supports in a direction perpendicular to, the centering of the die and the work can be automatically performed, and there is an effect that accurate deburring and screw forming are performed. Further, since the split type die uses a conventional circular die in half or less, it is inexpensive and can be easily replaced. Furthermore, since the pressing spring mechanism equipped with a pressing spring pressure regulator presses the die holding member, the pressing force of the split die surface on the workpiece screw can be adjusted, depending on the screw diameter and the degree of burr. There is also an effect that it can be adjusted to perform accurate and complete deburring.
