Description
本發明係涉及一種虎鉗;特別是指一種虎鉗之活動顎抑制浮動構造之創新結構型態揭示者。The present invention relates to a vise; in particular, it refers to the disclosure of an innovative structural form of the movable jaw restraining floating structure of a vise.
虎鉗是一種用於夾制工件的夾具,工件利用虎鉗夾制定位,可提高對該工件施以加工的方便性,虎鉗具有至少一活動顎,螺桿驅動該活動顎向著該工件移動,該活動顎接觸該工件後,該螺桿持續掣動該活動顎位移,藉此緊固夾持該工件時,該工件對該活動顎的相對作用力,可能會導致該活動顎產生上浮現象,影響該工件的定位精準度及夾持可靠度。A vise is a fixture used to clamp a workpiece. The workpiece is positioned by the vise, which can improve the convenience of processing the workpiece. The vise has at least one movable jaw, and the screw drives the movable jaw to move toward the workpiece. After the movable jaw contacts the workpiece, the screw continues to move the movable jaw to displace, so that when the workpiece is tightened and clamped, the relative force of the workpiece on the movable jaw may cause the movable jaw to float up, affecting the The positioning accuracy and clamping reliability of the workpiece.
M249762專利文獻公開一種習知虎鉗,其具有一基座體,該基座體的一端設有一固定顎,另一端樞組一活動顎,該活動顎的底端具有一滑座,該滑座設有一螺孔,該基座體組設一螺桿,該螺桿與該螺孔螺接,旋轉該螺桿可促使該活動顎相對於該固定顎位移,該滑座側向開設一圓穿孔,該圓穿孔的內部配合軸樞一圓柱體,該螺孔的中心線延伸通過該圓柱體的中軸線的上方,該圓柱體穿設一貫穿螺孔,該貫穿螺孔與該螺孔軸向相對,據使該貫穿螺孔與該螺孔形成同軸關係,該螺桿螺穿該貫穿螺孔,該螺桿旋轉驅動該活動顎向著該固定顎接近,且該活動顎及該固定顎相對夾制該工件時,該圓柱體對該滑座產生下壓作用,防止該活動顎產生向著離開該基座體的方向浮動的現象。Patent document M249762 discloses a conventional vise, which has a base body, one end of the base body is provided with a fixed jaw, the other end pivots a movable jaw, the bottom end of the movable jaw has a sliding seat, the sliding seat There is a screw hole, the base body is assembled with a screw, the screw is screwed with the screw hole, and the screw can be rotated to cause the movable jaw to move relative to the fixed jaw. The inner mating shaft pivots a cylinder, the center line of the screw hole extends above the central axis of the cylinder, and the cylinder is drilled with a through screw hole, the through screw hole is axially opposite to the screw hole, according to the The through screw hole forms a coaxial relationship with the screw hole, the screw rod is screwed through the through screw hole, the screw rod rotates and drives the movable jaw to approach the fixed jaw, and when the movable jaw and the fixed jaw clamp the workpiece relative to each other, the The cylinder presses down the sliding seat to prevent the movable jaw from floating in the direction away from the base body.
查,該習知虎鉗於實際應用經驗中發現仍舊存在下述問題與缺弊:該貫穿螺孔與該螺孔形成同軸關係,該螺孔的中心線通過該圓柱體的中軸線的上方,該貫穿螺孔的中心線並非與該圓柱體的中軸線相交,該貫穿螺孔通過該圓柱體的中軸線的上方,對該圓柱體加工形成該貫穿螺孔的困難度高,該貫穿螺孔容易產生軸向偏移的現象,影響該圓柱體抑制該滑座及該活動顎向著離開該基座體的方向浮動的可靠度,再者,該圓柱體軸樞組設於該圓穿孔後,需要旋轉該圓柱體,使該貫穿螺孔與該螺孔軸向相對,以利於該螺桿螺穿該貫穿螺孔,而該圓柱體缺乏可供操作的著力點,不易操作該圓柱體旋轉,且該圓柱體樞設於該圓穿孔的內部,不易觀察辨識該貫穿螺孔是否與該螺孔軸向相對,該圓柱體組設時的旋轉調節不易執行,習知虎鉗在該貫穿螺孔形成的加工及該圓柱體與該螺孔的組設的困難度高。Investigation, the conventional vise found in practical application experience that there are still the following problems and shortcomings: the through screw hole and the screw hole form a coaxial relationship, the center line of the screw hole passes through the top of the central axis of the cylinder, The center line of the through screw hole does not intersect with the central axis of the cylinder. The through screw hole passes above the central axis of the cylinder. It is difficult to form the through screw hole on the cylinder. The phenomenon of axial offset is easy to occur, which affects the reliability of the cylinder to restrain the sliding seat and the movable jaw from floating in the direction away from the base body. Furthermore, the cylinder shaft is assembled after the circular hole is assembled, It is necessary to rotate the cylinder so that the through screw hole is axially opposite to the screw hole, so as to facilitate the screw thread to pass through the through screw hole, and the cylinder lacks a force point for operation, so it is difficult to operate the cylinder to rotate, and The cylinder is pivoted inside the circular through hole, and it is difficult to observe and identify whether the through screw hole is axially opposite to the screw hole, and the rotation adjustment when the cylinder is assembled is not easy to perform. The conventional vise is formed in the through screw hole. The processing of the cylinder and the assembly of the screw hole are very difficult.
就另一方面而言,習知虎鉗利用該圓柱體的外周面與該圓穿孔的孔壁之間的相對作用力,使該圓柱體對該滑座產生抑制浮動的作用,但是,該圓柱體係配合軸樞於該圓穿孔,該外周面與該孔壁形成配合關係,使得該圓柱體對該滑座產生的抑制浮動的作用有待提升。On the other hand, the conventional vise uses the relative force between the outer peripheral surface of the cylinder and the hole wall of the circular hole to make the cylinder prevent the sliding seat from floating, but the cylinder The system cooperating shaft is pivoted to the circular hole, and the outer peripheral surface forms a cooperating relationship with the hole wall, so that the effect of restraining the floating of the sliding seat produced by the cylinder needs to be improved.
是以,針對上述習知虎鉗所存在之問題點,如何研發出一種能夠更具理想實用性之創新構造,實有待相關業界再加以思索突破之目標及方向者;有鑑於此,發明人本於多年從事相關產品之製造開發與設計經驗,針對上述之目標,詳加設計與審慎評估後,終得一確具實用性之本發明。Therefore, in view of the problems existing in the above-mentioned conventional vise, how to develop an innovative structure that can be more ideal and practical, it really needs the relevant industry to think about the goal and direction of breakthrough; in view of this, the inventors After years of experience in the manufacturing, development and design of related products, and after detailed design and careful evaluation for the above-mentioned goals, a truly practical invention was finally obtained.
