New description: [New technical field] The term “scale device” refers to a spindle clamping device that is mounted on the spindle of the machine tool to engage the pull rod head and clamp the handle. [Prior Art] The spindle clamping device of the conventional machine tool is disposed inside the main shaft, and includes an output end of a push rod connecting rod and a push rod combined with the push rod; wherein the push side = the outer side has a - end forming a protruding top block The money has a loop sleeve on the outer side of the top block for the outer position of the clip on the outer side of the push rod; the jaws are formed in an outer shape, and the end is opposite to the push end to clamp the action end of the knife handle. The outer side is in contact with the convex portion inside the main shaft to control the lost claw for external stretching and contraction. Taiwan Patent No. 1,299,955 discloses a red fixture, which comprises a jaw consisting of a plurality of clips, a limit ring and a spring; wherein one end of the limit ring is embedded at one end of the jaw; the push rod passes through The limit ring is partially located in the claw, the spring sleeve is outside the limit ring and the end is pressed against the limit ring. It is worth noting that since the limit ring and the push rod are not combined and fixed, they can generate phase riding with each other; in other words, t is converted into a miscellaneous broach or a combination of the limit ring and the jaw has a rotation. The trend of such a gripper--the side force distribution of the person holding the tool will not smoke, and the surface will cause the dynamic performance of the tool to perform processing, which affects the processing quality. [New content] The main purpose of this creation is to provide a machine tool spindle clamping device. The M374929 has the ability to optimize the dynamic characteristics of the tool and improve the processing quality. Another object of the present invention is to provide a "red machine spindle clamping device" which is capable of reducing the number of components and thereby reducing material costs and assembly costs to meet actual production requirements.

Referring to FIG. 2, the components of the clamping device 10 include a jaw 22, a pull-up head 24, and a --fixing jaw 26. The ten jaws 22 are gathered together by the plurality of claw pieces 28' and the elastic members 3G are used to bundle the ends of the claws 28 which have been gathered. The pull rod head 24 and the fixed claw 26 are assembled to one end of the jaw 22. Referring to Fig. 3, the pull rod head 24 is placed in the axial direction of the fixed claw %, and the M374929 pull (four) 24 is combined with the fixed claw 26 to form a relative motion. The tie rod head % is combined with the fixed claws 26 to form a lining means, which may be a heat sleeve combination, that is, the fixing claws 26 are tightly fitted on the rod head 24 by means of a heat shrinking manner. In addition, the combination of the puller_24 and the _claw 26 can be integrated into one body by the miscellaneous combination of the financial formula. The form in which the puller head 24 and the fixed claw are combined into one can be a pin joint, that is, The insertion of the claws such as the fixed claw % with the radial direction of the pull rod head 24 causes the pull-up 24 _ fixed jaw % to be combined without relative movement; see 4b ®, regarding the tie rod head 24 and the fixed wire 26 The form can be - body forming; please refer to the figure ~, about the combination of the transfer 4 and the fixed claw % can be combined with the ΐ ΐ dry head 24 tearing claws 26 respectively 34 and 36 and screwed together, so that the rod head 24 and the gorge The jaws 26 combine and do not create relative motion. Referring to Fig. 5, each of the claw pieces 28 constituting the jaws has a claw portion 38 which is positioned at the end of the claw portion 38 at the π portion; and the force inclined surface 44 connects the claw portion 38 ^ M2. The groove 46 is formed in the radial direction of the head... the groove is formed in the axial direction of the head 42. ^ Referring again to Figure 6, the plurality of claws 28 are gathered together such that:: the groove 46 is opposite to each other by the grooves, 22 sets are bundled in the respective grooves 46; then the claw pieces 28 are matched with the elasticity (four) The end of the claw-free fixing claw 26 is formed with a plurality of protruding projections 52, and each of the panels 52 extends toward the axial direction of the fixed claws; fixed at one end of the jaws 22, and each material/the joint of the heads 24 Matching, each defeated Gui 52 is embedded in each of the embedded slots. The ginseng read the phantom again, and the matching inclined surface 54 of the axial surface of the 1=- of the central claws of the central claws is clamped. When the pull (four) ^ slope 44 is opposite to the heart draw 12 inner wall itn - the axial movement of the dry stone mandrel 12, for example, according to the direction of the figure does not move to the right, the pull rod he holds the knife to the end of the 4-head. It is worthwhile to gather the claws 38, and the more the slanting surface 44 of the borrowing force is matched with the a = surface 54_with 'can improve the function of the clamping jaw 22 holding the knife handle 22=2 because the fixing claw 26 is combined with the pulling rod head 24 Integral, so please refer to Figure 7 to the right, the rod head 24 is displaced to the left in the direction of the figure, then the gallows 26 and the jaws 22 can be displaced to the left, and the sheets of the central claw a are released. Huan, so that the knife handle 14 can be taken out from the jaw r. Fig. 6 and Fig. 7 respectively illustrate the broaching action and the retracting action, and in the two movements, the wigs are smashed, and the claws are not moved. The rotation is generated; if the cool claws 22 do not rotate, the force distribution characteristics of the gripping handles 14 are uniform each time, so that the knife handles 14 can have good viability and improve the processing quality. Furthermore, the creation clip and the pull rod head are integrated into one body, so the two have the characteristics of synchronous movement 'there is no need to use the spring to drive the fixed claw as in the previous patent, which is characterized by a compact structure and helps to reduce the material. And set up costs. The above embodiments are merely illustrative of the technology and efficacy of the present invention, and not the M374929 is used to limit the creation of this work. Anyone who is familiar with this technology can swear under the thief of the technical principle that does not violate the technical principle. Therefore, the scope of protection of this creation should be as listed in the scope of patent application mentioned later.
