The utility model discloses an ultra-thin cavity formula hydraulic wrench is through setting up piston assembly and the hydro-cylinder of being connected with the drive plate to make oil pass through the inlet port that the oil circuit subassembly got into the hydro-cylinder, exert pressure to piston assembly, promote the drive plate motion, and drive actuating mechanism's pawl promotes the ratchet motion, and then make the bolt reach required requirement by motor-driven fastening, tear open the bolt and lean on motor-driven not hard up bolt, fastening torque is even, has improved efficiency, has reduced intensity of labour, and the convenience is used in narrow and small operation space.
Description
Technical Field
The utility model relates to a hydraulic wrench technical field particularly, relates to an ultra-thin cavity formula hydraulic wrench.
Background
The hydraulic wrench is a bolt fastening tool capable of outputting and setting torque, belongs to a high-pressure hydraulic tool, and is widely applied to equipment maintenance and installation in multiple industrial fields. The hydraulic wrench has two types of driving shafts and a hollow type. In the actual working process, because of the restriction of the operation space, the bolt is fastened by manpower to reach the required requirement, and the bolt is loosened by manpower in the process of disassembling the bolt, so that the fastening torque is uneven, the labor intensity is high, and the efficiency is low.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned technical problem among the correlation technique, the utility model provides an ultra-thin cavity formula hydraulic wrench can overcome prior art's the aforesaid not enough.
In order to achieve the technical purpose, the technical scheme of the utility model is realized as follows:
the utility model provides an ultra-thin cavity formula hydraulic wrench, includes the ratchet, the ratchet meshes with the pawl, the pawl passes through compression spring and is connected with the middle part of drive plate, the upper portion of drive plate is passed through piston assembly and is connected with the hydro-cylinder.
Further, the oil cylinder is connected with the oil way assembly.
Furthermore, an oil way communicated with the oil cylinder is arranged in the oil way assembly.
Further, the ratchet wheel is an inner hexagonal ratchet wheel.
Furthermore, one side of the pawl is provided with an adjusting pad.
The utility model has the advantages that: the utility model discloses an ultra-thin cavity formula hydraulic wrench is through setting up piston assembly and the hydro-cylinder of being connected with the drive plate to make oil pass through the inlet port that the oil circuit subassembly got into the hydro-cylinder, exert pressure to piston assembly, promote the drive plate motion, and drive actuating mechanism's pawl promotes the ratchet motion, and then make the bolt reach required requirement by motor-driven fastening, tear open the bolt and lean on motor-driven not hard up bolt, fastening torque is even, has improved efficiency, has reduced intensity of labour, and the convenience is used in narrow and small operation space.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1, according to the embodiment of the utility model provides an ultra-thin hollow formula hydraulic wrench, including ratchet 1, ratchet 1 and pawl 2 meshing, pawl 2 is connected through compression spring 8 and drive plate 3's middle part, one side of pawl 2 is equipped with adjusting pad 4, piston assembly 7 is passed through on drive plate 3's upper portion and is connected with hydro-cylinder 6, hydro-cylinder 6 is connected with oil circuit subassembly 5, be equipped with in the oil circuit subassembly 5 with the oil circuit of hydro-cylinder 6 intercommunication.
In one embodiment, the ratchet 1 is a hexagonal ratchet.
For the convenience of understanding the above technical solutions of the present invention, the above technical solutions of the present invention are explained in detail through specific use modes below.
When the device is used specifically, the oil circuit component 5 and the working head part are connected together through the connecting pin shaft, and the device can be used for achieving the locking and the dismounting of the bolt and the nut by being placed in a positive and negative mode.
When oil is fed, oil enters an oil inlet hole of the oil cylinder 6 through the oil circuit assembly 5, pressure is applied to the piston assembly 7, the driving plate 3 is pushed to move, and the pawl 2 of the driving mechanism and the ratchet 1 are driven to move.
During oil return, oil enters an oil return hole of the oil cylinder 6 through the oil circuit assembly 5, pressure is applied to the piston assembly 7, the driving plate 3 is pulled to move, and the pawl 2 and the compression spring 8 of the driving mechanism are driven to reset the driving mechanism.
To sum up, with the help of the above technical scheme of the utility model, piston assembly and hydro-cylinder through setting up being connected with the drive plate to make oil pass through the inlet port that oil circuit subassembly got into the hydro-cylinder, exert pressure to piston assembly, promote the drive plate motion, and drive actuating mechanism's pawl promotes the ratchet motion, and then make the bolt reach required requirement by motor-driven fastening, tear open the bolt and lean on motor-driven not hard up bolt, fastening torque is even, has improved efficiency, has reduced intensity of labour, and the convenience is used in narrow and small operation space.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
