The collet (4) includes a trough-shaped temple (41) recessed at an end surface of the shoulder (411) with an annular wall surface (413) having a wedge-shaped inner recess (412), the inner recess (412) and the sleeve The portion (37) is wedged to make the flange seat (41) of the main shaft (35) more stable. The flange seat (41) penetrates into a shaft tube (42) and is screwed tightly, the shaft officer (42) a occlusion member (421) is embedded in one end of the inner wall (36), and the end of the damper member (421) is provided with an inner tapered inlet (422) for an elastic member (43) and A collet (44) is successively inserted into the inlet (422), wherein the elastic member (43) against the occluding member (421) can be deformed by the collet (44), and the collet (44) is along The axial direction is provided with a long slit (441) which is cut away from the wall surface, and the slit (441) extends straight from the middle portion of the chuck (44) to one end of the octagonal shape of the bar D. In addition, the flange seat (41) is different from the inside. The outer portion of the recess (412) is screwed with a cap (45), the inner surface of the cap (45) abuts against the edge of the end of the collet (44), and the cap (45) is swiveled as soon as it is pushed. The collet (44) compresses the elastic element (43) Allowing the collet (44) to simultaneously control the rotation of the workpiece 'to facilitate the cutting step; to reversely rotate the cap (45) 'The collet (44) is pushed out by the elastic member (43) to release the workpiece The mandrel (39) sliding on the inner wall (36) of the main shaft (35), the 7 200906518 mandrel (39) facing one end of the elastic collet (4), screwed along with the mandrel (39) a sliding and displaced actuator (46) having a tapered end of the inlet (422) when the end of the closure member (421) is urged against the right side of the drawing by the actuator (46) The slit (441) forces the collet (44) to tightly grip the workpiece. Once the actuating member returns to the original position as the mandrel (39) slides, the resilient member (43) will withstand the occlusion member (421). When the shaft tube (42) is pushed down, the chuck (44) can no longer clamp the workpiece. The technical means of the present invention belongs to a composite spindle, and the above embodiment is the spindle. The turning chuck is assembled on the top, so the affirmation is called a turning type spindle; of course, the shaft can be assembled and converted. He turns the chuck or the milling chuck, so the spindle can also be called a milling spindle. Later, it will be mentioned in the conversion for turning or milling, so that the same spindle only needs to be replaced with a variety of chucks, reducing The occurrence of spindle inventory defects' and the coaxial composite mode solves the problems that the prior art can't overcome. May see the fourth figure's schematic diagram of the transmission mechanism (3) and even the spindle (35) structure, the same as above The embodiment is omitted, and in the drawing, the main shaft (35) is locked at one end of the socket portion (37) with a flange seat (5) adjacent to the end of the main shaft (35). The radial projection-shoulder (51)' is fixed via the shoulder (51) locking flange seat (1); the main shaft (35). The flange seat (5) is located at the end face of the shoulder (y). The annular wall surface (52) has a wedge-shaped inner recess (53), and the inner recess (53) and the sleeve portion (37) are wedged. The flange seat (5) of the (1) is more stable. The middle portion of the flange seat (5) has an inner cone 200906518 hole (54) for the known shank (18) to penetrate the inner taper hole. (54), a milling spindle (35) constituting a drawing tool. The mandrel (39) slides in an inner wall (36) of the main shaft (35), the mandrel (39) faces the flange seat (5) One end of the joint is screwed to a joint (55), and the joint (55) extends toward the shank (18) to extend a thin neck portion (551) having a head having a large cross-sectional width at the end of the thin neck portion (551). (552) A cylindrical member (56) assembled to the inner wall (36) of the main shaft (35) has an inner diameter (561), the inner diameter (561) being larger than the other portion of the length of the shank portion, the head ( 552) Drilling into the narrower inner diameter (561) of the cylindrical member (56), and connecting a plurality of clamping jaws (5 8 ) between the head (552) and the tubular member (56) by using a plurality of beads (57) ▲The clamping jaw (58) is at the claw end (581). The function shape is set. Ten, * the mandrel (39) moves to the right side of the drawing, and the clamping jaw (58) loses the limitation of the inner diameter (561) of the cylindrical member (56), with the bead (57) as the axis. The heart can swing freely, and at the same time, the shank (18) is the neck 〇 9) of the flange seat (5), which can penetrate the movable range of the jaws (58) of the jaws (581). Once the mandrel (39) moves to the left side of the drawing, the claw end (581) of each clamping jaw (58) is twisted with the inner diameter (561) to clamp the neck 〇 9), so that the shank (18) follows the main shaft (35) Rotate together. According to the above two embodiments, the same spindle is mounted on the collet (4), which is a turning type spindle, which can be used for turning the workpiece; on the contrary, the coaxial connection of the mounting flange seat (5) is converted into a milling spindle, which can be clamped. Tool holder (μ) = The tool mills the workpiece so that the turning and milling operations can be done on the coaxial 'Hone has broken the bottleneck of the prior art. Next, looking at the fifth figure, the figure shows that the main shaft (35) is inserted into the sleeve portion (37) 9 200906518 two= -shaped flange seat (6), and the flange seat (4) has a shoulder (6) and a protrusion along each side. a receiving portion (62), wherein the inner diameter (63) is adjacent to the shoulder (61), and a wall surface of == (37) is provided ((4), and the flange seat (6) is locked via the shoulder (8) Fixed to the main shaft (35). The receiving portion (62) is locked with the multi-claw (22.) of the collet (22), and the collet (22) is driven to rotate by the main shaft (35) according to the method = (6). Forming a boring type main shaft (35). Continuing with the sixth figure, the figure shows that the main shaft (35) is locked at the end of the ferrule portion (37) with an annular flange seat (7), one side of the flange seat (7) The recess is a load-bearing portion (71)' for the known palm-type collet (72) to be inserted into the bearing portion (71) to be locked to the flange seat (7). The aforementioned palm-shaped chuck π-Chuck is before the applicant In March and May of the same year, the technical product of the Taiwan Invention Certificate No. 1253361 was filed, and the content can be viewed in the case of the case. The flange seat (7) is in the inner diameter ( 73) a position adjacent to the insertion sleeve portion (37), a wall surface (74) that fits the wedge surface (38), locking the flange seat (7) on the end surface of the main shaft (35) 'the flange seat (?) together with the palm collet (72) The main shaft (35)-domain rotates to form a turning type spindle (35) that holds the workpiece. As mentioned above, this case has the characteristics of a composite main shaft, which breaks through the prior art bottle, in a comprehensive machine tool, lathe or milling machine, etc. In the mechanical transmission mechanism, the same spindle is used with different flanges to hold workpieces or tools for turning or sharpening. The patents that have been in line with novelty and progress are all technical contents. It should be within the scope of the right to the case. 200906518 [Simple diagram of the diagram], a diagram is a cross-sectional plan view of the known milling spindle. f diagram is a schematic cross-sectional view of the main vehicle of the turning type.
