The specific embodiment
Embodiment 1:
Shown in Fig. 1 to 3; The multifunctional wrench of the automatic lock uint of the described band hydraulic pressure of the utility model comprises wrench body 1; With integrally formed fixedly Hubei Province 2 of wrench body 1 and can be along movable Hubei Province 3 that the clamping direction moves; Fixing Hubei Province 2 one end openings, movable Hubei Province 3 connects hydraulic pushing devices, is provided with the storage tank 4 of ccontaining movable Hubei Province 3, hydraulic pushing device in the wrench body 1.
In the present embodiment, hydraulic pushing device comprises preceding hydraulic cylinder 5, the movable catch bar of main hydraulic pressure 6 one end connection activity Hubei Province 3; The other end connects promotes mainly into spring 7; The movable catch bar 6 of main hydraulic pressure is through promoting mainly into spring 7 the insides, and promoting mainly into, spring 7 is supporting the rear portion in movable Hubei Province 3 and the front portion of preceding hydraulic cylinder 5 respectively; Thereby thrust is provided for movable Hubei Province 3; The rear end in movable Hubei Province 3 is provided with the opening of swallow-tail form, and movable catch bar 6 front ends of main hydraulic pressure are the swallow-tail form front end, and realization activity Hubei Province 3 is connected with the movable catch bar 6 of main hydraulic pressure like this.Rotary type hydraulic oil stop valve 8 inserts locking grooves 9, locking groove 9 be provided with preceding hydraulic cylinder 5, back hydraulic cylinder 10 be communicated with to discharge orifice 15.
Locking groove 9 other ends connect back hydraulic cylinder 10, the movable catch bar 11 of back hydraulic cylinder 10 auxiliary connection hydraulic pressure, and movable catch bar 11 other end auxiliary connection propelling springs 12 of secondary hydraulic pressure, secondary propelling spring 12 other ends are resisted against storage tank 4.
Mode that can be through the liquid medium transmission between the movable catch bar 11 of movable catch bar 6 of main hydraulic pressure and secondary hydraulic pressure promotion activity Hubei Province 3 under the effect of promoting mainly into spring 7 and secondary propelling spring 12 is carried out meshing, and through rotate rotary type hydraulic oil stop valve 8 control before hydraulic cylinder 5 and the convection current of back hydraulic cylinder 10 inner high voltage hydraulic oil realize the locking of meshing mouthful of spanner.
The operating process of present embodiment is:
Under the normal condition; Movable Hubei Province 3 is under the effect of promoting mainly into spring 7 and secondary propelling spring 12; With wrench body 1 fixedly the 2 meshing mouthfuls of working faces in Hubei Province engage, rotary type hydraulic on spanner oil stop valve 8 is in "open" state, at this moment before high-pressure and hydraulic oil in the hydraulic cylinder 5, back hydraulic cylinder 10 be in can be to stream mode; Movable 3 meshing in Hubei Province is in mobilizable state, and spanner is locking not.
When needs (loosening, tighten) nut; Because movable Hubei Province 3 is in mobilizable state under the normal condition; Through promotion activity Hubei Province 3 backward, movable Hubei Province 3 promotes the movable catch bar 6 of main hydraulic pressure, and the high-pressure and hydraulic oil in the preceding hydraulic cylinder 5 are promoted hydraulic cylinder 10 convection current backward by the movable catch bar 6 of main hydraulic pressure; The hydraulic oil of convection current simultaneously under the static pressure effect of liquid medium with the movable catch bar 11 of secondary hydraulic pressure to pusher, the spanner working hole opens.After nut is put into; Movable Hubei Province 3 is under the effect of promoting mainly into spring 7 and secondary propelling spring 12; With nut closely tooth due to fixing Hubei Province 2 meshing mouthfuls with movable Hubei Province 3 between, under the effect of secondary propelling spring 12, back hydraulic cylinder 10 interior high-pressure and hydraulic oil are promoted hydraulic cylinder 5 convection current forward by secondary hydraulic pressure activity catch bar 11; The hydraulic oil of convection current simultaneously pushes away the movable catch bar 6 of main hydraulic pressure forward under the static pressure effect of liquid medium; And pressure acted on movable Hubei Province 3 simultaneously, and making to form between wrench body 1, nut, movable Hubei Province 3 threes and combine closely, spanner is meshing.
Then; Rotate rotary type hydraulic oil stop valve 8 to "off" state; At this moment the hydraulic oil between preceding hydraulic cylinder 5 and the back hydraulic cylinder 10 is closed discharge orifice 15; Before hydraulic cylinder 5 stop convection current with high-pressure and hydraulic oil in the back hydraulic cylinder 10, preceding hydraulic cylinder 5 is in full closeding state, the preceding hydraulic cylinder 5 closed state under is the static pressure that main hydraulic pressure activity catch bar 6 and movable Hubei Province 3 provide enough powerful liquid medium; Spanner realizes that hydraulic pressure is sealed automatically, and (loosening, tighten) operation just can be carried out to nut in the automatic sealed back of spanner realization hydraulic pressure.
When carrying out nut (loosening, tighten) operation, can use by turns in 14 of the supporting plug-in type activity of the different bores single direction ratchet that the slot 13 at main working hole and wrench body 1 rear portion is pegged graft, thereby increase work efficiency.
