Description
技术领域 technical field
本实用新型涉及机械制造领域，具体涉及一种钻孔用夹具。 The utility model relates to the field of mechanical manufacturing, in particular to a clamp for drilling.
背景技术 Background technique
在机械制造过程中，夹具是一种装夹工具的工艺装备，它直接影响着工件的加工精度、劳动生产率和生产成本等。在企业的产品设计、制造以及生产技术准备过程中，夹具占有极其重要的地位。 In the process of mechanical manufacturing, fixture is a kind of process equipment for clamping tools, which directly affects the machining accuracy, labor productivity and production cost of the workpiece. Fixtures play an extremely important role in the product design, manufacturing and production technology preparation process of an enterprise.
目前，我国常用的夹具有五大类，分别为：通用夹具、专用夹具、可调夹具、组合夹具和自动化生产用夹具等。 At present, there are five categories of fixtures commonly used in my country, namely: general fixtures, special fixtures, adjustable fixtures, combined fixtures and fixtures for automated production.
夹具因工件加工表面的不同而有不同的结构形式，钻床夹具体结构大致可分为以下几个部分：定位元件、夹紧装置、导向对刀元件、连接元件、夹具体等。 The fixture has different structural forms due to the different machining surfaces of the workpiece. The specific structure of the drill press clamp can be roughly divided into the following parts: positioning components, clamping devices, guiding tool setting components, connecting components, clamping bodies, etc.
夹具在装夹工具时，其主要功能是使工件定位和夹紧。其中，定位是通过工具定位基准面与夹具定位面接触或配合实现的。正确的定位可以保证工件加工表面的尺寸和位置精度要求。夹紧是防止工件加工时出现松动、脱落，为工件提供安全、可靠的加工环境。 When the fixture is clamping the tool, its main function is to position and clamp the workpiece. Wherein, the positioning is realized by contacting or cooperating with the positioning reference surface of the tool and the positioning surface of the fixture. Correct positioning can ensure the size and position accuracy requirements of the workpiece processing surface. Clamping is to prevent the workpiece from loosening and falling off during processing, and to provide a safe and reliable processing environment for the workpiece.
由于钻床进给运动较少，钻头结构特点，钻削加工往往精度较低，在进行多孔加工时孔距精度难以保证。因此，钻床夹具是保证钻削精度的重要保证。 Due to the less feed movement of the drilling machine and the structural characteristics of the drill bit, the precision of the drilling process is often low, and it is difficult to guarantee the accuracy of the hole distance when performing multi-hole machining. Therefore, the drilling fixture is an important guarantee to ensure the drilling accuracy.
目前，常用的钻床为台钻、立式钻床和摇臂钻床，适用于工件上不同规格孔系的加工。钻孔时通常采用的钻模结构有固定式、翻转式和盖板式等。但由于上述钻模为专用夹具，不能适用多孔和不同规格孔的加工，并且在移动或翻转夹具时造成误差的累积。 At present, commonly used drilling machines are bench drills, vertical drilling machines and radial drilling machines, which are suitable for processing holes of different specifications on workpieces. The drilling template structures usually used in drilling include fixed type, flip type and cover type. However, since the above-mentioned drilling template is a special fixture, it cannot be applied to the processing of holes with different specifications, and errors will accumulate when moving or turning over the fixture.
因此，为了在工件中加工出满足较高精度要求的孔及孔系，需要设计一种移动坐标钻孔夹具。 Therefore, in order to process holes and hole systems that meet higher precision requirements in the workpiece, it is necessary to design a moving coordinate drilling fixture.
