Description
本發明係涉及一種中心虎鉗;特別是指一種中心虎鉗調校定位構造之創新結構型態揭示者。The invention relates to a center vise; in particular, it refers to an innovative structural type revealer of the adjustment and positioning structure of the center vise.
中心虎鉗是一種具有一對活動夾顎的虎鉗,各該活動夾顎彼此相對,設於虎鉗主體的一導螺桿具有二螺紋段,且各該螺紋段的螺紋旋向相反,各該螺紋段分別螺穿各該活動夾顎,旋轉該導螺桿,可驅動各該活動夾顎同步地相對靠移或反向遠離,各該活動夾顎能夠快速地相對夾制一工件或快速地解除對該工件的夾制,針對多個相同規格的工件反覆執行相同的加工工序時,利用中心虎鉗夾持工件,可以加速工件的定位及快速置換相同規格的工件。The center vise is a vise with a pair of movable jaws, and the movable jaws are opposite to each other. A lead screw provided on the main body of the vise has two threaded sections, and the threaded direction of each threaded section is opposite. The thread segments are threaded through the movable jaws respectively, and by rotating the lead screw, the movable jaws can be driven to move or move away from each other synchronously. Each movable jaw can quickly clamp a workpiece or release quickly. For the clamping of the workpiece, when the same processing procedure is repeated for multiple workpieces of the same specification, the center vise is used to clamp the workpiece, which can accelerate the positioning of the workpiece and quickly replace the workpiece of the same specification.
查,該習知結構於實際應用經驗中發現仍舊存在下述問題與缺弊:各該活動夾顎未夾持工件時,定義各該活動夾顎彼此間具有一虛擬的中點,該中點是各該活動夾顎相對靠移時的行程終點,若該中點偏移了該虎鉗主體的中心點,將迫使各該活動夾顎反向遠離時的最大行程縮減,影響各該活動夾顎所能夾制工件的最大尺寸,故而,中心虎鉗產製組裝時,必需執行該中點的調校及定位,就另一方面而言,中心虎鉗夾制工件進行加工的過程中,刀具對該工件所施予的作用力及加工過程可能產生的振動現象,可能造成該導螺桿的定位產生若干偏移現象,從而影響各該活動夾顎相對夾制工件時,該工件與該刀具的相對定位,影響對該工件加工的精度,據此,該中點必需能夠適時地調校其定位,藉由調節該導螺桿於該虎鉗主體的定位,即可達成所述該中點的調校;然而,改變該導螺桿於該虎鉗主體的定位時,習知中心虎鉗經常需要變動該虎鉗主體在空間中的姿態,例如,先解除該虎鉗主體於加工機具的機台的安裝,再翻轉該虎鉗主體使其底面朝上,以利於解除該固定塊與該虎鉗主體的連接,調校完成,將該固定塊與該虎鉗主體重新連接後,再度翻轉該虎鉗主體使其頂面朝上,以利於將該虎鉗主體再次安裝於該機台,而該虎鉗主體的翻轉操作需留意避免發生掉落或碰撞事件,以防砸傷人員或機具或造成中心虎鉗損壞的意外事件;再者,習知中心虎鉗之導螺桿的調整及定位的相關結構複雜,零組件多,導致生產及組裝的成本增加、組裝費時。It is found that the conventional structure still has the following problems and shortcomings in practical application experience: when each movable jaw does not clamp the workpiece, it is defined that each movable jaw has a virtual midpoint between each other, the midpoint It is the end of the stroke when the movable jaws are relatively moved. If the midpoint deviates from the center point of the vise body, the maximum stroke of the movable jaws will be reduced when the movable jaws move away in the opposite direction, which will affect the movable jaws. The maximum size of the workpiece that can be clamped by the jaw. Therefore, when the center vise is produced and assembled, the adjustment and positioning of the midpoint must be performed. On the other hand, when the center vise is clamping the workpiece for processing, The force exerted by the tool on the workpiece and the vibration phenomenon that may occur during the machining process may cause the positioning of the lead screw to be offset, thereby affecting the relative clamping of the workpiece by the movable jaws, the workpiece and the tool The relative positioning affects the accuracy of the workpiece processing. According to this, the midpoint must be able to adjust its positioning in a timely manner. By adjusting the positioning of the lead screw on the vise main body, the midpoint can be achieved. Adjustment; however, when changing the positioning of the lead screw on the vise main body, the conventional central vise often needs to change the posture of the vise main body in space, for example, first release the vise main body on the machine table of the processing tool After the installation of the vise, turn the main body of the vise so that the bottom face upwards to facilitate the release of the connection between the fixing block and the vise main body. After the adjustment is completed, the fixing block is reconnected to the vise main body, and then the vise is turned over again. The top surface of the main body of the vise faces upwards to facilitate the re-installation of the main body of the vise on the machine, and the turning operation of the vise main body should be careful to avoid falling or collision incidents, in order to prevent injury to personnel or machinery or cause The accidental event of damage to the center vise; in addition, the related structure of the adjustment and positioning of the lead screw of the conventional center vise is complicated, and there are many parts and components, which leads to an increase in production and assembly costs and time-consuming assembly.
