Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is circular table, and 2 is ear seat, and 3 is shoulder hole, and 4 is piston, and 5 is piston rod, and 6 is reversal valve, and 7 is pressure head, and 8 is increment bar, and 9 is pilot sleeve, and 10 is pilot bushing, and 11 is groove, and 12 is sealing ring.
Detailed description of the invention
As shown in Figure 1, air clamper, comprises circular table 1, is arranged on the ear seat 2 of circular table 1 both sides; Described circular table is provided with shoulder hole 3 (this shoulder hole is step-like blind hole or is furnished with the step-like through hole of end cap), is slidably provided with pneumatic means in this shoulder hole 3; Described pneumatic means comprises the piston 4 being positioned at the large radius end of shoulder hole, and is positioned at shoulder hole minor radius end and the piston rod 5 be connected with piston; The outer surface of revolution of described circular table 1 is provided with the reversal valve 6 controlling pneumatic means motion; The rod end chamber that described piston and shoulder hole roof are formed is provided with air inlet, outlet passageway, the plunger shaft that described piston and shoulder hole bottom surface are formed establishes air inlet, outlet passageway, described reversal valve is communicated with rod end chamber air inlet, outlet passageway and plunger shaft air inlet, outlet passageway, realizes the communication of air-flow, cut-out and commutation; Described piston rod end is dismountable is connected with the rounded pressure head in cross section 7.
During use, connect air pump by reversal valve and control pumping of pneumatic means piston, and piston rod end is connected with for the pressure head by Work-sheet pressing, by moving up and down of the Sports band dynamic head of piston, compress being set in the cylindrical work be positioned at below pressure head on piston rod.
Because some cylindrical work height is higher, and the stroke of piston rod is limited; For the problems referred to above, preferably, can be provided with increment bar 8 between described pressure head 7 and piston rod 5 end, these increment bar 8 two ends are dismountable to be respectively connected with pressure head, piston rod end.The stroke being increased piston rod by increment bar is convenient to clamp highly higher cylindrical work.
Preferably, pilot sleeve 9 is provided with between described shoulder hole minor radius end and piston rod.When piston rod movement, good guide effect is played to piston rod.
Preferably, pilot bushing 10 is provided with between the large radius end of described shoulder hole and piston.When piston movement, good guide effect is played to piston.
Preferably, described piston is provided with groove 11, is provided with sealing ring 12 in this groove 11.Sealing ring plays good sealing function.
Preferably, be detachably connected as described in and be threaded.Convenient disassembly.
