Description
技术领域 technical field
本实用新型涉及螺栓与安装孔之间的定位领域，具体是一种定位防脱套筒。 The utility model relates to the field of positioning between bolts and mounting holes, in particular to a positioning anti-off sleeve.
背景技术 Background technique
定位套筒被广泛应用于：汽车、摩托车、装载机、挖掘机、电动工具、风动工具、加工机床、矿山机械、建筑机械等各种机械产品。其作用主要是：使具有装配或配合关系的两个工件之间能够保证精确的定位作用；有时也会用来防止两个工件之间的相对滑动，造成连接螺栓断裂的情况。 Positioning sleeves are widely used in: automobiles, motorcycles, loaders, excavators, electric tools, pneumatic tools, processing machine tools, mining machinery, construction machinery and other mechanical products. Its main function is to ensure accurate positioning between two workpieces that have an assembly or matching relationship; sometimes it is also used to prevent relative sliding between two workpieces, resulting in the breakage of connecting bolts.
目前配合螺栓联接使用的常见定位套筒主要有两种形式。第一种是需要在联接与被联接工件上，开专用的定位孔进行使用，但是该形式增加了加工成本；第二种是将定位套筒套在连接螺栓上，减小螺栓与安装孔之间的间隙，进而达到其功用，但在安装过程中，经常会出现螺栓与套筒或者与工件脱离掉落的情况。 At present, there are two main types of common positioning sleeves used with bolted connections. The first is to open a special positioning hole on the connecting and connected workpieces, but this form increases the processing cost; the second is to put the positioning sleeve on the connecting bolt to reduce the distance between the bolt and the mounting hole. However, during the installation process, it often occurs that the bolts and sleeves or the workpiece are separated and dropped.
发明内容 Contents of the invention
本实用新型为了解决目前配合螺栓联接使用的常见定位套筒存在的诸多缺陷，提供了一种定位防脱套筒。 The utility model provides a positioning anti-off sleeve in order to solve many defects existing in common positioning sleeves used in conjunction with bolt connections.
本实用新型是通过以下技术方案实现：一种定位防脱套筒，包括可与连接螺栓套插配合的筒体，所述筒体其中一端部周身剪切有若干朝筒体内侧的内锁止片，另一端部周身剪切有若干朝筒体外侧的外锁止片；每个内锁止片和外锁止片均是其中一侧为固定侧，另外三侧为自由侧；并且每个内锁止片和外锁止片上与固定侧相对的自由侧均指向筒体中部。 The utility model is realized through the following technical solutions: a positioning anti-loosening sleeve, including a cylinder body that can be plugged and matched with the connecting bolt, one end of the cylinder body is cut with a number of inner locks facing the inside of the cylinder body The other end is cut with a number of outer locking pieces facing the outside of the cylinder; one side of each inner locking piece and outer locking piece is a fixed side, and the other three sides are free sides; and each The free sides opposite to the fixed side on the inner locking piece and the outer locking piece both point to the middle of the cylinder body.
具体使用时，内锁止片一端朝向螺帽套插于连接螺栓上，其内锁止片与螺栓上的螺纹卡位配合，使得定位防脱套筒与连接螺栓保持相对固定无法脱离，形成一个装配体；带有定位防脱套筒的连接螺栓通过安装孔装配到工件上，其外锁止片与工件卡止配合，工件被固定在螺帽与外锁止片之间，装上螺母即可。筒体消除了连接螺栓与安装孔之间的间隙，而且能够避免工件将连接螺栓顶出脱落。 In specific use, one end of the inner locking piece faces the nut sleeve and is inserted on the connecting bolt, and the inner locking piece cooperates with the screw thread on the bolt, so that the positioning anti-off sleeve and the connecting bolt remain relatively fixed and cannot be separated, forming a Assembly; the connecting bolt with the positioning anti-off sleeve is assembled to the workpiece through the mounting hole, and the outer locking piece is engaged with the workpiece, and the workpiece is fixed between the nut and the outer locking piece, and the nut is installed. Can. The cylinder eliminates the gap between the connecting bolt and the mounting hole, and can prevent the workpiece from pushing out the connecting bolt and falling off.
本实用新型所述定位防脱套筒，与现有技术相比，具有如下有益效果：①设计结构精巧、便于批量制作生产，并且制造成本低；②结构简单，操作方便，无需设置专用定位孔与定位销；③在装配使用过程中，无需担心螺栓或套筒因安装孔位对不正而被顶出脱落。 Compared with the prior art, the positioning anti-off sleeve of the utility model has the following beneficial effects: ①The design structure is exquisite, convenient for mass production, and the manufacturing cost is low; ②The structure is simple, the operation is convenient, and no special positioning holes are required and positioning pins; ③During assembly and use, there is no need to worry about bolts or sleeves being pushed out due to misalignment of the mounting holes.
