最近我厂设计了一种能在带T形槽的工作台面上快速调整的无级单立柱夹紧装置,见图1。此夹紧装置能绕立柱在任何方面、沿立柱的任何高度夹紧工件,经使用,操作方便,夹紧可靠。夹紧装置的结构是:带内螺纹的T形块11与机床工作台12相配,立柱4一端外螺纹与T形块的内螺纹拧紧。滑套5与立柱为动配合,以使滑套能沿立柱上下升降,并能使滑套绕立柱旋转。在滑套的缺口中装入锁紧缺10,用圆柱销9连接,在锁紧块上所铣的槽是让夹紧螺钉7定位的,以保证夹紧可靠。操作时,先将带有T形块的立柱沿工作台T形槽移动到适当位置,并使立柱、T形块和工作台紧固。然后压紧工件进行加工。为了立柱和T形块配合使用,应根据机床T形槽
Recently, our factory designed a stepless single-column clamping device that can be quickly adjusted on a work surface with a T-shaped groove, as shown in FIG. 1. The clamping device can clamp the workpieces on the column at any height and height along the column. It is easy to operate and the clamping is reliable after use. The structure of the clamping device is that the T-shaped block 11 with internal thread is matched with the machine table 12, the external thread at one end of the column 4 is tightened with the internal thread of the T-shaped block. Slide sleeve 5 and the column for the dynamic fit, so that the sleeve can move up and down along the column, and can make the sleeve around the column rotation. In the gap of the sliding sleeve into the lack of locking 10, with a cylindrical pin 9 connected to the locking block on the groove milling is to allow the positioning of the clamping screw 7, in order to ensure reliable clamping. Operation, first with the T-shaped column along the table T-slot to move to the appropriate location, and the column, T-block and the table fastening. Then press the workpiece for processing. For use with studs and T-blocks, T-slots should be machined
