Description of the invention (1) The present invention relates to a design of a two-way center-seeking vise, especially a vise design for clamping a work object. By virtue of its two-way screw, double hook and movable jaw structural characteristics and combination relationship, It is composed of a bidirectional centering vise that can be clamped externally or by clamping, which is convenient for gripping the work to find its center to facilitate the processor. According to the traditional vise 10 structure (as shown in the tenth figure), a vise body 100 with a protruding fixed jaw 101 on the front end is usually provided, and an activity is placed on the vise body 100. The jaw 10 2 extends the movable jaw 10 2 into the vise body 100, thereby screwing a lower part of the movable jaw 1 0 2 with a lead screw 103 and exposing the lead screw 103 to the vise. The 100 end of the main body constitutes a vice capable of unidirectionally holding a work object, so that the machine can process the work object. Secondly, another structure of a center-seeking vise 20 (as shown in the eleventh figure) is attached to a vise body 2 0 0 and a movable jaw 2 0 1 is respectively arranged at the upper end of the vise to extend the lower part of the movable jaw 2 01. Go to the vise body 2 0 0, so that the guide screw 2 03 which is set as a left and right spiral at both ends is threaded on the lower part of the two movable jaws 2 01, and the lead screw 2 0 3 is exposed at the end of the vise body 2 0 0 By this means, one lead screw 2 0 3 can be driven to simultaneously drive two movable jaws 2 0 1 to hold the center-seeking vise for holding the work object to obtain the center. If the user positions the center-seeking vise 20 at When the machine is on the machine, the work can be quickly clamped to position its center, so that users can conveniently use the machine to perform work center processing. Moreover, the above-mentioned center-seeking vise 20 can also be provided with a fixed jaw 2 0 4 on the vise body 2 between two movable jaws 2 0 1 (as shown in the twelfth figure), so that the two can be held simultaneously. Work. However, the conventional center-seeking vise can only clamp the outside of the work, and cannot be held in the groove or round hole on the inside of the work. If the periphery of the work is irregular, the conventional center-seeking vise I.e. unable to perform its function;

Description of the invention (4) Movable jaw 4, which is a clamping jaw that can hold a work object, has a gate-shaped seat shape, and is provided with a <-shaped groove 4 1 at the front and rear of the interior, respectively. The slot 41 is used for the above-mentioned re-hook lever 3 3, and the inner and outer end faces of the movable jaw 4 are provided with a clamping pad 4 2, 4 2 ′ that can be detached and disassembled to form a double-sided clamping work. Among them, (as shown in the sixth figure), the clamping pad 4 2 of the movable jaw 4 may be provided with a V-shaped groove 4 2 1 at the center to hold a circular work object and perform centering; or The surface of the clamping cymbal 4 2 ′ can be cut into an arc surface 4 2 Γ or any other structure. It can be seen that the clamping pads 4 2 and 4 2 of the present invention are not limited to the early pure sheet structure; Therefore, (as shown in the first figure), the upper ends of the two double-hook blocks 3 are selected and placed into two portal-shaped hollow movable jaws 4, respectively, so that the double-hook levers 3 abut against the inner front and rear sides of the movable jaw 4. The groove 4 1 is used to fix the rehook block 3 and push the movable jaw 4 in both directions. If so, the lower part of the second rehook block 3 is inserted into the vise body 1. In the slot 11 on the surface, two movable jaws 3 and 4 can be slid on the vise body 1, and the above-mentioned one-way screw 2 is put into the screw socket 12 to extend into the vise body 1. And the left spiral section 22 and the right spiral section 2 Γ are screwed in the guide screw holes 31 of the second hook block 3 respectively, so that the second hook block 3 can be controlled to move the second movement when the two-way screw 2 is configured to rotate Jaws 4 are clamped outwards or vice versa. In the application of the bidirectional centering vise of the present invention (as shown in the fourth figure), if a larger work piece 40 is encountered or the inner recessed hole 4 0 1 of the work piece 40 is required to be processed in the center, the work piece 4 The recessed hole of 0 4 0 1 is set on a vise. Using the design of the two or two re-hook blocks 3 of the present invention, the re-hook lever 3 3 can be moved by the two movable jaws 4 to be clamped outwards, so that the two movable jaws 4 can be used.

518269 五、發明說明（5) 孔4 0 1 ，以獲致夾持及求心之效果（如第四圖所示即求取 凹孔4 0 1 之中心A )，若此不僅不必使用大型虎鉗，亦可 供使用者方便針對工作物4 0之凹孔4 0 1 中心加工。 其次，（如第五圖至第七圖所示）本發明雙向求心虎鉗 如應用於大量圓環形工作物5 0之夾持加工時，係可令該二 活動顎4對靠夾持一物（如第五圖所示），然後切削二活 動顎4外側該持墊片4 2 ’ 之片面成為一圓弧面4 2 Γ結構， 若此即可藉二複鉤塊3其中複鉤桿3 3推移二活動顎4外張 夾持之設計，令二活動顎4以外側撐固該工作物5 0之圓孔 50 1 ，以獲致夾持及求心之功能（第七圖所示即求取圓孔 5 0 1 之中心A )，達到供使用者方便針對中心加工之效果 〇 再者，（如第八圖及第九圖所示）本發明亦可藉旋轉 雙向螺桿2 ，使二活動顎4對靠夾持小形之工作物6 0、7 0 ，且因内側該夾持墊片4 2係設有一 V形槽4 2 1 ，故可穩固 夾持圓形工作物6 0並獲得求心效果（第八圖所示即求取中 心A )，且於夾持矩形工作物7 0時，亦可獲得穩固夾持及 求心效果（第九圖所示即求取中心A )。 由上述可見本發明藉雙向螺桿2 、複鉤塊3及活動顎 4之結構特徵及組合關係設計，係足以改善習見虎鉗難以 夾持大型工作物及無法針對凹槽、圓孔求心夾持之缺點， 使虎鉗更臻實用並適於裝置在大量加工之生產線。 綜上所述，本發明所為之『雙向求心虎鉗』設計，其 技術手段之運用出於新穎無疑，且功效與設計目的誠然符518269 V. Description of the invention (5) Hole 4 0 1 to obtain the effect of clamping and centering (as shown in the fourth figure, the center A of the concave hole 4 0 1 is obtained). If not only do not need to use large vise, It is also convenient for users to process the concave hole 4 0 1 of the work 40 center. Secondly, (as shown in Figures 5 to 7) when the two-way centering vise of the present invention is applied to a large number of circular-shaped workpieces 50 for clamping processing, the two movable jaws 4 can be held against one another. (As shown in the fifth figure), and then cut the one side of the holding pad 4 2 ′ outside the two movable jaws 4 into a circular arc surface 4 2 Γ structure. 3 3 The design of the second movable jaw 4 is clamped outwards, so that the second movable jaw 4 supports the circular hole 50 1 of the workpiece 50 to the outside to obtain the function of clamping and seeking. Take the center A of the circular hole 5 0) to achieve the effect of center processing for the user. Furthermore, (as shown in Figure 8 and Figure 9) the present invention can also rotate the two-way screw 2 to make the two move The jaws 4 hold small work pieces 60 and 70, and because the inner side of the holding pad 4 2 is provided with a V-shaped groove 4 2 1, it can hold the round work piece 6 0 firmly and obtain the center Effect (the center A is obtained as shown in the eighth figure), and a stable clamping and centering effect can also be obtained when holding a rectangular workpiece 70 (see the ninth figure Take center A). It can be seen from the above that the present invention uses the two-way screw 2, the hook block 3, and the movable jaw 4 to design structural features and a combination relationship, which is sufficient to improve the conventional vise's difficulty in clamping large work objects and the inability to pinch the grooves and round holes. Disadvantages make the vise more practical and suitable for installation in a large-scale processing production line. To sum up, the design of the "two-way heart-seeking vise" designed by the present invention uses the technical means for novelty and undoubtedly, and the efficacy and the design purpose are true.
