When the workpiece is accommodated and the axial movement is rearward, the stacked magazine of the moving (four) will be compressed. When the power source disappears, the restoring force of the stacked yellow will push the spindle forward, so that the forced Hold the workpiece tightly.次(d) The second object of the present invention is to provide a mandrel lathe mandrel, the power source has a cylinder and the rainbow system can be placed on one side of the shaft sleeve or at the end of the shaft. Two types of materials are available, and the second __ can achieve the same effect. Therefore, it is necessary to select a position type user according to space or work habits. The purpose of this is that, in the case of providing a mandrel lathe mandrel with a mandrel in operation, the stacking spring of the turning mechanism generates a spring force pushing against the mandrel and thereby making the pressing sleeve a class of tapered grooves. Tightening (4) pressing the elastic tube tightly, so that the workpiece is firmly clamped in the elastic collet. With regard to the techniques, means and efficiencies of the present invention, a preferred embodiment will be described in detail with reference to the drawings, and it is believed that the structural features of the above-mentioned object 1274612 of the present invention can be obtained from To understanding. [Embodiment] The present invention provides a heart-and-shaft design for a heart-type lathe. (4) Make it lack of step-by-step understanding of the structural design and technology of the present invention. I would like to explain it in conjunction with the first to seventh figures: See the figure of the brother, a type of ### U 1 ^ lathe mandrel, mainly The system has an I-axis, (1) 'the shaft sleeve (1) is respectively threaded with: shaft = (2), which has - is placed on the sleeve (1) m:), the mandrel (21) The front end link is set to 2: and it is different from the end of the pressing sleeve (22) with - ( 2 2 1 ) and a shoulder (2 i 2) with a slight diameter reduction, and the pressing sleeve (2 2) The leading edge is provided with a class of tapered grooves (2 2 ' for a corresponding level of the tapered groove (the elastic tube 2 3 in the form of a clip (2 1)), and the elastic collet ( 2 3) with the pressing phase) _ class tapered groove (2 2 1 ) is provided with _ elastic member, in the embodiment the elastic member (2 4 ) f 4 ^ is a yellow, the elastic member ( 2 (22) - Rotating device (3), which has a mandrel bushing (the mandrel bushing (3U is covered with a mandrel (21) and a pressing sleeve (= body (1)) is located at the end of the pressing sleeve (2 2) The system has a cover "closed, the axis of the cover (32) has a perforation" L' The outer edge of the bushing (31) is additionally provided with an oil seal (3, a plurality of materials (34), a rotor (35), an outer jacket 1274612 ten stators (= the outer edge of the rotor (35) After the stator (38) is energized, the rotation of the rotor (3 5) should be driven, and the rotation 3 5 ) will drive the mandrel sleeve (3 1 ) to rotate synchronously. " - The recovery mechanism (4) has a stack Shaped Bodhi Washer (..., (43) and a c-type buckle (44) (=夂, the parts are respectively placed in the kit (3 7) One (2 1 ) iB S, /77 The two ends of the shaft have - washers (42), (43), = (41 into the mandrel (3 1) disc body (211) stand: = C-type buckle (44) is positioned, another pad [(43 ) is the shoulder (212) of the 2 1). The loop (42) is applied to the mandrel (a power source (5), which has a cylinder (5 cylinders (5 1 ) is a pneumatic cylinder Or - in the example, with gas as the description, and the cylinder (5 = piston rod (...), the piston rod (5; u, rear moving t-span (512), and two jumpers (5 hearts == sleeve (1) to form, (52) = mandrel (2 2) is different from the piston rod (5 1 1 ) end of the system to push its disk body (2 = when f piston rod ( 511) When retracting, the eye is as shown in the second figure. When the tension sleeve (22) is required to release the 1274612 collet (2 3), the cylinder 11) is retracted backward to allow the two jumpers. 5) convex: the piston rod (5, wt moon (5 1 2) and the piston rod (5 1 1) pivotal end interlocking, while the jumper piece (512) is in the middle position: therefore, the second span The tabs (5^) are different from the striking body 1 1) The end system forms an outwardly convex pendulum arc, and this == "512" is pushed backwards to the mandrel (21) Cong Cong C 2 1 1 ), let the mandrel f tighten the sleeve (2 2) of the class cone 枰 (= move to drive the (23) 1 ± Λ 2 13 loose the elastic tube cool. Full-steep clamp (23) for the workpiece (Α) to be worn, please refer to the third and fourth figures) Press the elastic collet (2 3)昧,... 2 2 Stretching the Japanese A The shaft (2 1 ) is convex back. The return mechanism (4) accommodated in the kit (37) will be moved backwards. [^] The stack of elastics (41) will be: the same as the mandrel (2) When the compression line of the U-moving stroke disappears with the power of the stack of magazines...and red), the compression stroke of "^ (41) will generate a -recovering force, and return the folded material (41) to the normal state. And (4) pushing the shoulder (212) of the heart '(21) to push the mandrel 2 2 to move forward: the stepping groove (3) of the pressing sleeve (") is not tightened to the workpiece (A) 23 ), let the elastic tube inflammation (2, this 'the mandrel sleeve (3 U middle position ring is provided with the rotor (' and the rotor (3 5) outer edge is sleeved with the stator (3 8), 1274612 : Haizizi (3 8) will generate the rotor (3 5) after the power is turned on - the drive should drive the rotor (3 5) to rotate, and when the rotor (3 5) turns, the mandrel (2 1) will be linked. The mandrel sleeve (3 1 ) rotates synchronously, and the drive shaft is driven by the elastic collet (2 3) Reading (A) - Rotating 'other' The outer edge of the mandrel sleeve (3 1 ) has bearings (3 4) and outer bushings (3 6 ) to ensure the mandrel sleeve ( 3 1) Reduce the wear of the mandrel sleeve (3丨) and increase the stability effect at high speed. In addition, when the invention is in normal operation, the stacking spring (4 1 ) of the return mechanism (4) will Producing - the elastic force is pushed against the mandrel (2 i ), so that the pressing sleeve (2 2) of the tapered sleeve (2 2 i) is tightly pressed against the elastic collet (2 3) to ensure the workpiece (A) firmly clamped in the elastic collet (23). Of course, there are still many examples of the present invention, and only the details change therebetween. The fifth and sixth figures of the tea are shown in the present invention. In the second embodiment, the cylinder (6 work) of the power source (6) is disposed on the side of the mandrel (2 1 ) different from the pressing sleeve (2 2 ), and the cylinder (6丄) The system has a ring set on the mandrel (the piston of the Sichuan (611), and 6 1 1 ) is located near the mandrel (2 1 ) - the piston ring (6" 2 ), when the cylinder (6 work) Piston (6 when driving backwards, drive the piston ring (6 1 2) Pushing the disc body (2 ii ) to move the mandrel ( 2 1 ) backward. When the driving force of the cylinder block (6 1 ) disappears, the stacked spring of the compressed return mechanism (4) (41), will push the ring (4 2) to the shoulder of the car (2 1 ) (2 work, so that the mandrel ( 1274612 2 1 ) moves forward, drive the tightening sleeve (22) The class tapered groove (2 ID - presses the elastic collet (23) as shown in the seventh figure. , jade by the above 5 brothers after the 'can find the center of the heart of the lathe, the lathe has the following characteristics · · 1 go ~ type lathe spindle is used - the cylinder drive disk body, so that the heart The forced sleeve is loosened to release the elastic collet for the workpiece to be placed. 2 ♦ When the driving force of the cylinder disappears, the compressed stack of elastics will
