Abstract
The utility model discloses a hydraulic wrench, and relates to the technical field of machining tools. The hydraulic wrench comprises a ratchet wrench body. A handle of the ratchet wrench body is arranged inside a shell. An opening is formed in the shell. A sleeve is connected to the position of the opening. A working head of the ratchet wrench body is arranged inside the sleeve. The outer wall of the working head of the ratchet wrench body is in sliding fit with the inner wall of the sleeve. A hydraulic jack for driving the handle of the ratchet wrench body to rotate is arranged inside the shell. A handle and a pressure meter of the hydraulic jack extend out of the shell. Compared with the prior art, the hydraulic wrench can solve the problem that an existing ratchet handle wastes labor in use and is inconvenient to use.
Description
Technical field
The utility model relates to the machine tools technical field, the instrument of especially a kind of labour-saving swivel bolt or nut.
Background technology
existingly a kind ofly be placed in the bolt of narrow or inaccessible position or the ratchet spanner of nut for rotation, its working portion is square shaft or many ribs axle, one week of middle part of axle is provided with tooth, match with the movable latch with extension spring of outer casing inner wall setting, shell with handle so as the operation, under normal condition, this movable latch snaps in the tooth at axle middle part, turning handle, handle drives that extension spring in shell is pulled out tooth with movable latch and along with handle drives the rotation of shell and snaps in next tooth, realize back-outing or tightening for the bolt or the nut transfer function power that act on axle by the relative motion of shell and axle.Although this ratchet spanner played the effect that turns to, but the power that is subjected to when it is pulled has not been delivered on handle with still subduing, the operator manually removes to pull handle, still very require great effort, if increase the length of handle to increase kinetic moment, although can reduce the power that the operator applies on handle, increased the material cost of handle, and carried and deposited all inconvenient.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of hydraulic spanner, effort when using to solve existing ratchet handle, inconvenient problem.
In order to address the above problem, the technical solution adopted in the utility model is: this hydraulic spanner includes ratchet spanner, the handle of described ratchet spanner is arranged in a housing, described housing is provided with an opening, described opening part links a sleeve, the working head of described ratchet spanner is placed in described sleeve, the outer wall of the working head of described ratchet spanner and the inwall of described sleeve are slidably matched, be provided with the hydraulic jack of the handle rotation that drives described ratchet spanner in described housing, the handle of described hydraulic jack and Pressure gauge stretch out described housing.
In above-mentioned technical scheme, more specifically scheme can also be: the hydraulic stem top of described hydraulic jack and the handle of described ratchet spanner connect, and are provided with the extension spring of the handle that connects described ratchet spanner in described housing.
Further: described housing is L-type.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
This hydraulic spanner replaces manually pulling the handle of ratchet spanner by hydraulic jack, the handle return is assisted in extension spring, make original very hard spanner become very laborsaving, and operating efficiency is improved; Adopt the housing of L-type, and be provided with the sleeve of placing ratchet spanner, easy to use; The handle of hydraulic jack and Pressure gauge stretch out outside housing, and whether convenient force value of observing hydraulic jack arrives desired value, handle handled easily jack.
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is that A in Fig. 1 is to view.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing enforcement:
Hydraulic spanner as shown in Figure 1 and Figure 2, it comprises ratchet spanner 1, ratchet spanner 1 comprises working head 1-1, square shaft 1-2 in the middle of working head, also comprise handle 1-3, in the handle 1-3 of ratchet spanner 1 has been arranged at a housing 2, housing 2 is provided with an opening, described opening part links a sleeve, the working head 1-1 of ratchet spanner 1 is placed in described sleeve, the outer wall of the working head 1-1 of ratchet spanner 1 and the inwall of described sleeve are slidably matched, and square shaft can be by the hole of this sleeve, and the fixed ratchet wheel spanner 1 so preferably.Also be provided with the hydraulic jack 3 of the handle 1-3 rotation of driving pawl spanner 1 in housing 2, this housing 2 is L-type, includes by hinged and dish and links the Di Hegai that connects, and housing 2 can select the high and lightweight PVC plastics of intensity to make.The hydraulic stem top of hydraulic jack 3 and the handle 1-3 of ratchet spanner 1 connect, and the handle of hydraulic jack 3 and Pressure gauge 5 and stretch out this housing 2 also are provided with the extension spring 4 of the handle 1-3 that connects ratchet spanner 1 in housing 2.
during work, be set on the nut that to back-out or to tighten after the square shaft of ratchet wrench 1 one side is sleeved, the operator holds wrench on the other hand, shake on the other hand the handle of jack hydraulic, along with stretching out of the hydraulic stem of hydraulic jack 3, the handle 1-3 of ratchet spanner 1 also rotates along arc, nut is back-outed or tightened, extension spring 4 simultaneously also is elongated thereupon, the hydraulic stem of hydraulic jack 3 pushes up ratchet spanner 1 handle 1-3 on the pressure-reducing valve of opening hydraulic jack 3 after certain arc, regain hydraulic stem, the handle 1-3 of ratchet wrench 1 also gets back to original position under the effect of extension spring 4 convergent forces, repeatedly work nut button " pine " or " tightly " like this, this hydraulic spanner is turned over one side, use the square shaft of ratchet wrench 1 another side, as above operation can be turned round nut to opposite direction.
