Are formed respectively. Two fastening bolts 52 are inserted into the elongated holes 23g and screwed into the bolt holes 50f of the connecting wall 50b. Therefore, these two fastening bolts 52 can be fastened from the front of the multi-needle sewing machine M. By loosening these fastening bolts 52 from the front, the mounting member 50 is connected to the connecting frame 23 via the long hole 23g. The vertical position can be adjusted with respect to (main body frame 21). A protruding portion 50d protruding forward is formed at the center portion of the lower wall 50c, and is fixed in a state where the protruding portion 50d is inserted into the recessed portion 51a of the posture regulating member 51.

  The posture regulating member 51 is made of a synthetic resin material having a low coefficient of friction and wear resistance. As shown in FIGS. 4 and 5, the lower side of the posture regulating member 51 is a flat surface 51b (hereinafter referred to as a lower surface 51b). The upper side of the posture regulating member 51 is formed on a partial cylindrical surface 51 c, and the partial cylindrical surface 51 c is disposed in parallel with the inner cylindrical surface 25 a of the rotating frame 25. That is, the cylindrical central axis of the partial cylindrical surface 51 c and the cylindrical central axis of the inner cylindrical surface 25 a of the rotating frame 25 are arranged in parallel. The curvature radius R1 of the partial cylindrical surface 51c of the posture regulating member 51 is formed to be larger than the curvature radius R2 of the inner cylindrical surface 25a of the rotating frame 25. Therefore, the left and right end portions 51 d and 51 e on the upper surface of the posture regulating member 51 are in contact with the inner cylindrical surface 25 a of the rotating frame 25.

This state will be described with reference to the schematic diagram shown in FIG. In FIG. 6, the corner chamfers at the left and right ends of the upper surface of the posture regulating member 51 are omitted for the sake of simplicity.
As shown in FIG. 6, the curvature radius R1 of the partial cylindrical surface 51c of the posture regulating member 51 is larger than the curvature radius R2 of the inner cylindrical surface 25a of the rotating frame 25. 51e and the inner cylindrical surface 25a of the rotating frame 25 are in contact with each other, and other portions are not in contact with each other. As described above, the posture regulating member 51 and the inner cylindrical surface 25a of the rotating frame 25 are in line contact with each other at two left and right end portions 51d and 51e of the posture regulating member 51.

Next, the operation and effect of the cylindrical frame device 20 will be described.
First, as shown in FIG. 8, the two fastening bolts 52 are loosened and the attachment member 50 is moved downward with respect to the connection frame 23, so that the lower surface 51 b of the posture regulating member 51 is brought into contact with the upper surface 4 a of the cylinder bed 4. The two fastening bolts 52 are fastened in the contacted state.

  Next, as shown in FIG. 9, when the four fastening bolts 32 are loosened and the rotating frame 25 is moved downward with respect to the connecting frame 23, the inner cylindrical surface 25 a of the rotating frame 25 becomes the posture regulating member. 51, a position where the partial cylindrical surface 51 c abuts, that is, a position where the upper portion of the inner cylindrical surface 25 a of the rotating frame 25 contacts the left and right end portions 51 d and 51 e of the upper surface of the posture regulating member 51. Movement to is regulated. At this position, the four fastening bolts 32 are fastened. At this time, a predetermined minute gap (for example, a gap of 0.5 mm) is formed between the upper and lower surfaces 4b and 4c connected to the upper surface 4a of the cylinder bed 4 and the upper part of the inner cylindrical surface 25a of the rotating frame 25. Since it is provided, the rotation frame 25 can be smoothly rotated.

  As described above, the posture regulating member 51 that is in sliding contact with the upper surface 4a of the cylinder bed 4 and the upper portion of the inner cylindrical surface 25a of the rotating frame 25, and the mounting for fixing the posture regulating member 51 to the main body frame 21 so that the vertical position can be adjusted. Therefore, by adjusting the vertical position of the mounting member 50, the vertical position of the rotating frame 25 with respect to the upper surface of the cylinder bed 4 can be easily adjusted by adjusting the vertical position of the mounting member 50. . Therefore, a predetermined minute gap can be reliably ensured between the upper surface of the cylinder bed 4 and the inner cylindrical surface 25a of the rotating frame 25 without using a thickness gauge or the like.

  The lower side of the posture regulating member 51 is formed on the flat surface 51 b, and the upper side of the posture regulating member 51 is formed on the partial cylindrical surface 51 c, and this partial cylindrical surface 51 c is parallel to the inner cylindrical surface 25 a of the rotating frame 25. Therefore, the partial cylindrical surface 51c of the posture regulating member 51 abuts on the inner cylindrical surface 25a of the rotating frame 25, and the posture regulating member 51 securely holds the adjusted vertical position of the rotating frame 25. can do.

  Since the radius of curvature R1 of the partial cylindrical surface 51c of the posture regulating member 51 is larger than the radius of curvature R2 of the inner cylindrical surface 25a of the rotating frame 25, only the left and right end portions 51d and 51e on the upper surface of the posture regulating member 51 rotate. It contacts the inner cylindrical surface 25a of the frame 25. For this reason, the contact area of the partial cylindrical surface 51c of the posture regulating member 51 with respect to the inner cylindrical surface 25a of the rotating frame 25 is reduced, and the partial cylindrical surface 51c and the partial cylinder of the posture regulating member 51 when the rotating frame 25 rotates. The frictional force with the surface 51c is reduced. Therefore, the rotation frame 25 can be smoothly rotated with respect to the main body frame 21. Further, since the rotating frame 25 is supported by the left and right end portions 51d and 51e on the upper surface of the posture regulating member 51, the rotating frame 25 can be stably supported. Further, since the posture regulating member 51 is made of a synthetic resin material having a low friction coefficient and wear resistance, the main body frame 21 with respect to the cylinder bed 4 can be moved smoothly. The rotation frame 25 can be smoothly rotated. And durability of the attitude | position control member 51 can be improved. Moreover, the manufacturing cost of the attitude | position control member 51 can be reduced.

Next, a modified example in which this embodiment is partially modified will be described.
1] In this embodiment, the partial cylindrical surface 51c of the posture regulating member 51 and the inner cylindrical surface 25a of the rotating frame 25 are arranged in parallel, but the length of the posture regulating member 51 in the front-rear direction is short. Therefore, it may be arranged so that it is not strictly parallel but substantially parallel.
2] The radius of curvature R1 of the partial cylindrical surface 51c of the posture regulating member 51 is not larger than the radius of curvature R2 of the inner cylindrical surface 25a of the rotating frame 25, but the radius of curvature of the inner cylindrical surface 25a of the rotating frame 25. It may be equal to R2, or may be smaller than the radius of curvature R2 of the inner cylindrical surface 25a of the rotating frame 25. However, in this case, the effect that the rotating frame 25 is supported at the two left and right end portions 51d and 51e on the upper surface of the posture regulating member 51 cannot be expected.

3] The upper surface of the attitude regulating member 51 may be a flat surface instead of a partial cylindrical surface. Further, it may be a partial spherical surface.
4] In addition, those skilled in the art can implement the present invention by adding various modifications to the embodiments without departing from the spirit of the present invention, and the present invention includes such modifications. .
