技术领域 technical field
本发明有关一种夹具，旨在提供一种尤适用于微细切削刀具的加工、研磨时，将细切削刀具夹持、定位的夹具结构。 The present invention relates to a fixture, and aims to provide a fixture structure that is especially suitable for clamping and positioning the fine cutting tool during processing and grinding of the fine cutting tool.
背景技术 Background technique
按，微细切削乃一种为满足微小型精密部件的加工需求，而依循传统切削基础所发展的微加工技术，目前已见广泛应用于微型注塑模具、光学组件、集成电路等加工制造流程。至于，微细切削的基本原理主要在精密（超精密）切削机床上，利用微细切削刀具去除工件上的多余材料，使之成为在形状、精度和表面质量等方面符合要求的微小型精密部件。 By the way, micro-cutting is a kind of micro-machining technology developed on the basis of traditional cutting to meet the processing needs of micro-miniature precision components. It has been widely used in the processing and manufacturing processes of micro-injection molds, optical components, and integrated circuits. As for the basic principle of micro-cutting is mainly on precision (ultra-precision) cutting machine tools, micro-cutting tools are used to remove excess material on the workpiece, making it a micro-precision component that meets the requirements in terms of shape, precision and surface quality.
由此可知，微细切削技术的发展主要仰赖于微细切削刀具技术的支撑；原则上，适用于微细切削的刀具应必须至少具备：局部特征尺度微小、切削刃锋利、表面质量好、强度高、刚性好，以及耐磨性好等特性，且其对于自身的尺寸精度及准确度要求亦相对较高。 It can be seen that the development of micro-cutting technology mainly depends on the support of micro-cutting tool technology; in principle, tools suitable for micro-cutting should at least have: small local feature scale, sharp cutting edge, good surface quality, high strength, rigidity Good, and good wear resistance and other characteristics, and its requirements for its own dimensional accuracy and accuracy are relatively high.
因此，在对微细切削刀具的本体进行加工、研磨过程中，尤须确实将其本体夹制、固定，以避免因为微细切削刀具的本体走位而影响其尺寸精度。又，为了维持微细切削刀具的加工产能，用以固定类似杆状被加工物的夹具，最好具有动作迅速、准确的优点。 Therefore, in the process of processing and grinding the body of the micro-cutting tool, it is especially necessary to clamp and fix the body of the micro-cutting tool, so as to avoid affecting the dimensional accuracy of the micro-cutting tool due to the movement of the body of the micro-cutting tool. Also, in order to maintain the processing capacity of the micro-cutting tool, it is preferable that the jig used to fix the rod-like workpiece has the advantages of fast and accurate movement.
传统连杆式的夹具虽然可以利用两个夹持部同时相对开、合而达到将被加工物快速固定的目的，但其机械式的连杆传动机构对于微细的夹持动作而言，相对较难掌控其夹持部的行程准确度，以及夹持的力道；尤其，传统连杆式夹具的两个夹持部以类似剪刀刀刃运动的方式相对靠合，容易在与被夹持物接触时，将被夹持物朝向夹持部开口的方向推挤，反而容易让微细的被夹持物走位，将严重影响被夹持物的定位效果。 Although the traditional link-type clamp can use the two clamping parts to open and close at the same time to achieve the purpose of quickly fixing the workpiece, but its mechanical link transmission mechanism is relatively slow for the fine clamping action. It is difficult to control the stroke accuracy of the clamping part and the force of the clamping; especially, the two clamping parts of the traditional link clamp move relative to each other in a manner similar to the movement of the blades of scissors, and it is easy to contact the clamped object. Pushing the object to be clamped toward the opening of the clamping part will easily cause the tiny object to be clamped to move, which will seriously affect the positioning effect of the clamped object. ``
发明内容 Contents of the invention
本发明所解决的技术问题即在提供一种尤适用于微细切削刀具的加工、研磨时，将细切削刀具夹持、定位的夹具。 The technical problem to be solved by the present invention is to provide a fixture which is especially suitable for clamping and positioning the fine cutting tool when processing and grinding the fine cutting tool.
为达上述目的，本发明的夹具在一基座上透过两组内部链带一体联结有两个可相对位移的活动钢件，该两个活动钢件之间并一体连接有一外部链带延伸至该基座的外侧，以供接受相关器械的推顶，整体夹具即可在外部链带的牵引的下，使该两个活动钢件与该基座相对位移，并且经由精密计算内部链带回绕、配置方式，以及内部链带各部位厚薄度差异的设计，使两个活动钢件以近乎平行的运动方式相对位移。 In order to achieve the above purpose, the fixture of the present invention is integrally connected with two movable steel parts that can be displaced relative to each other through two sets of internal chain belts on a base, and an external chain belt is integrally connected between the two movable steel parts to extend to the outside of the base to accept the pushing of related instruments, the overall fixture can make the two movable steel parts relative to the base under the traction of the external chain belt, and through precise calculation of the internal chain belt The winding, configuration, and the design of the difference in thickness of each part of the internal chain belt make the two movable steel parts relatively displaced in a nearly parallel motion.
而能够以较为直接、精准的动作方式朝向被夹持物靠近，以避免被夹持物走位；甚至可以分别控制两个活动钢件的移动速度，由其中一个活动钢件首先到达被夹持物的定位处，再由另一活动钢件对被夹持物施予夹制力量，相对较容易掌控实际的定位效果，以及较能够维持定位可靠度。 It can approach the clamped object in a more direct and precise way to avoid the clamped object from moving; it can even control the moving speed of the two movable steel parts separately, and one of the movable steel parts will first reach the position of the clamped object At the position, another movable steel part exerts a clamping force on the clamped object, which is relatively easy to control the actual positioning effect and can maintain the positioning reliability.

该两个活动钢件12分别透过该两组内部链带13与该基座11的主体相联结，并可与该基座11相对位移；另有两块夹体15供分别安装在各活动钢件12的靠合处，各夹体15设有至少两个定位孔151及至少一螺丝孔152，各活动钢件12则设有与该夹体15相对应的定位孔121及螺孔122，以供利用定位梢161及螺丝162将两块夹体15分别安装于各活动钢件12上。 The two movable steel parts 12 are respectively connected to the main body of the base 11 through the two groups of internal chain belts 13, and can be relatively displaced with the base 11; At the abutment of the steel parts 12, each clip body 15 is provided with at least two positioning holes 151 and at least one screw hole 152, and each movable steel part 12 is provided with a positioning hole 121 and a screw hole 122 corresponding to the clip body 15 , for utilizing the positioning pin 161 and the screw 162 to install the two clips 15 on the movable steel parts 12 respectively.
该外部链带14连接于该两个活动钢件12之间，并相对延伸至该基座11外部供与接受如图所示的气压缸30或其它相关器械的推顶，并可在其与相关器械相接触的部位设有一凹部141，以增加接触连接效果。 The external chain belt 14 is connected between the two movable steel parts 12, and relatively extends to the outside of the base 11 for and accepts the pushing of the pneumatic cylinder 30 or other related equipment as shown in the figure, and can be connected with it A concave portion 141 is provided at the contacting part of the instrument to increase the effect of contact connection.
如图3所示，本发明的夹具10可以采用线切割或放电加工等方式将内部链带13及外部链带14周围多余的部位去除，使形成内部链带13及外部链带14等构造，使当外部链带14受相关器械(如图1所示的气压缸30)推顶时，整体夹具10即可在外部链带14的牵引之下，使该两个活动钢件12与该基座11相对位移，并可经由精密计算各内部链带13回绕、配置方式，以及各部位厚薄度差异的设计，使该两个活动钢件12以近乎平行的运动方式相对位移。 As shown in Fig. 3, the clip 10 of the present invention can adopt methods such as wire cutting or electrical discharge machining etc. to remove the extra parts around the inner chain belt 13 and the outer chain belt 14, so that structures such as the inner chain belt 13 and the outer chain belt 14 are formed, When the external chain belt 14 is pushed to the top by related equipment (such as the pneumatic cylinder 30 shown in Figure 1), the overall clamp 10 can be pulled by the external chain belt 14 to make the two movable steel parts 12 and the base The relative displacement of the seat 11 can make the relative displacement of the two movable steel parts 12 in an almost parallel motion through the precise calculation of the winding and arrangement of each internal chain belt 13 and the design of the thickness difference of each part.
而能够以较为直接、精准的动作方式朝向被夹持物靠近，以避免被夹持物走位；甚至可以分别控制两个活动钢件12的移动速度，由其中一个活动钢件12首先到达被夹持物的定位处，再由另一活动钢件12对被夹持物施予夹制力量，相对较容易掌控实际的定位效果，以及较能够维持定位可靠度。 Instead, it can approach the clamped object in a more direct and precise manner to avoid displacement of the clamped object; it can even control the moving speed of the two movable steel parts 12 separately, and one of the movable steel parts 12 will reach the clamped object first At the positioning position, another movable steel part 12 exerts a clamping force on the clamped object, which is relatively easy to control the actual positioning effect and can maintain the positioning reliability.
