Detailed description of the invention
Below in conjunction with accompanying drawing and by embodiment, the present invention is described in further detail, and following example are explanation of the invention and the invention is not limited in following example.
Embodiment 1:
Referring to Fig. 1 to Fig. 3, clamping tool for processing eccentric shaft of the present invention includes connecting plate 1, support brace 2, fixing plate 3, positioning sleeve 4, spring 5, locating piece 6, formwork 7, hold-down column 8, tie rod 9, V-block 10, pressure strip 11, rag iron spring 12 and clamping sleeve 13, and described connecting plate 1, support brace 2, formwork 7 and clamping sleeve 13 are sequentially coaxially installed.
The cavity being provided with through in described positioning sleeve 4, locating piece 6, spring 5, positioning sleeve 4, fixing plate 3 combine installation successively, spring 5 is located in the cavity of positioning sleeve 4, spring 5 one end props up fixing plate 3, the other end props up locating piece 6, positioning sleeve 4 is fixing with fixing plate 3 to be connected, and bolt 14 passes through fixing plate 3, spring 5 and positioning sleeve 4 threadeds with locating piece 6, and fixing plate 3, spring 5, positioning sleeve 4 and locating piece 6 are installed and be combined as overall structure I.
It is provided with cavity body 71 in described formwork 7, overall structure I and V-block 10, pressure strip 11 are installed in formwork 7, V-block 10 and formwork 7 fixedly mount, the " T " shape shape of formwork 7, cavity body 71 in formwork 7 is rectangular, described overall structure I, pressure strip 11, V-block 10 outline rectangular, and height is close with cavity body 71, and therefore this overall structure I, pressure strip 11, V-block 10 are fixed at rotational axis direction with formwork 7.
Being provided with rag iron spring 12 between V-block 10 and pressure strip 11 and support connection, the tension force of rag iron spring 12 makes to leave between V-block 10 and pressure strip 11 gap, convenient loading workpiece 15, facilitates again and take out after operation terminates.
Connecting plate 1 is fixed with formwork 7 after being connected and is internally formed a cavity II, and support brace 2 can move in this cavity II.
The sidewall of formwork 7 is provided with perforate 72, and hold-down column 8 is located in this perforate 72, and hold-down column 8 one end props up pressure strip 11.
