在机械加工过程中,测量工件的偏摆、直线度以及表面相对位置的偏差等时,利用千分表支架支承千分表,进行测量工件是经常的事。这里介绍一种如图所示的组合式万能千分表架,它比一般的表架用途广而准。如在车削内孔时,在没有杠杆式千分表条件下,可用一般标准千分表1,插入表座支臂10上直径φ8毫米的轴套内,用紧固螺钉3固定住,通过表座支臂10上的杠杆11,就可测量孔的偏摆或直线度等。表座支臂10靠栓杆4、栓杆螺帽2、夹箍5、紧杆18和拉紧帽17,紧固于侧杆9上,并能使千分表在任何位置和角度来检验工件。
In the machining process, the measurement of the workpiece deflection, straightness and the relative position of the surface deviation, the use of dial indicator support dial indicator, the workpiece is measured frequently. Here is a combination of universal indicator as shown in the table, it is more widely used than the average table frame. Such as the turning bore, in the absence of lever-type dial indicator can be used standard dial gauge 1, inserted into the table seat arm 10 diameter φ8 mm sleeve, with the fastening screw 3 fixed by the table Seat lever 10 on the arm 10, you can measure the deviation of the hole or straightness. Table seat arm 10 by bolt 4, bolt nut 2, clamp 5, tight rod 18 and tension cap 17, fastened to the side rod 9, and can make the dial indicator at any position and angle to test Workpiece.
