Abstract
The utility model discloses a hydraulic torque wrench, which comprises a blade hydraulic motor, a star-shaped reduction gear set and an output shaft, wherein the blade hydraulic motor is provided with a plurality of star-shaped reduction gear sets; the output end of the vane hydraulic motor is connected with an output shaft. This neotype beneficial effect has overcome the shortcoming of traditional hydraulic pressure torque wrench, can rotate towards a direction in succession, and in addition, it also can conveniently take off when last tight bolt, can rotate star type reduction gear group according to the moment of torsion circumstances of difference, if the big moment of torsion of needs output, can rotate two or a plurality of star type reduction gear group. Several gear sets are connected in series, so that large torque can be output, and bolts with different torques can be screwed.
Description
Technical Field
The utility model relates to the field of wrenches, in particular to a hydraulic torque wrench.
Background
The hydraulic wrench is a tool for screwing the bolt, and fig. 3 is a structure of the conventional hydraulic wrench, when the bolt is tightened, the hydraulic wrench can only rotate from one direction, and after the bolt is tightened, the bolt can apply a reverse acting force to the wrench, so that the wrench is difficult to take down; when the spanner is used, the bolt is tightened in a repeated operation process, when hydraulic oil enters the right side of the piston 12 from the port B, the piston 12 moves to the left side, and the piston 12 pushes the ratchet wheel 11 to rotate anticlockwise. But when the piston 12 moves to the leftmost side, the piston stops, at this time, the reversing valve 13 needs to be operated to make the port A feed hydraulic oil, the piston 12 is pushed back to the right, and when the piston 12 returns to the right, the port B feeds hydraulic oil instead, so that the ratchet wheel 11 rotates to tighten the bolt.
It is therefore desirable to design a hydraulic torque wrench that overcomes the disadvantages of conventional hydraulic torque wrenches, that can be continuously rotated in one direction, that can be easily removed when tightening bolts, that can rotate the planetary reduction gear sets according to different torque conditions, and that can rotate two or more planetary reduction gear sets if a large torque needs to be output. Several gear sets are connected in series, so that large torque can be output, and a hydraulic torque wrench which can screw bolts with different torques is necessary.
SUMMERY OF THE UTILITY MODEL
The present invention provides a hydraulic torque wrench which can solve the problems mentioned in the background art.
The utility model provides a hydraulic torque wrench, which comprises a blade hydraulic motor, a star-shaped reduction gear set and an output shaft, wherein the blade hydraulic motor is provided with a plurality of star-shaped reduction gear sets; the output end of the vane hydraulic motor is connected with an output shaft.
Preferably, the output shaft is a structure arranged along the axial direction of the output end of the vane hydraulic motor; the output shaft is connected with the sleeve.
Preferably, a plurality of said planetary reduction gear sets are connected in series.
Preferably, a rubber sleeve is mounted on the housing of the vane hydraulic motor.
According to the hydraulic torque wrench provided by the utility model, the output end of the vane hydraulic motor can continuously rotate towards one direction, but the output end of the vane hydraulic motor is smaller than the piston torque on the traditional hydraulic torque motor, the output torque of the vane hydraulic motor can be amplified through the star-shaped reduction gear set, the output shaft can be made into a direction structure, the output shaft can be directly connected with the sleeve, the defects of the traditional hydraulic torque wrench are overcome, the vane hydraulic motor can continuously rotate towards one direction, in addition, the vane hydraulic motor can be conveniently taken down when a bolt is tightened, the star-shaped reduction gear set can be rotated according to different torque conditions, and if large torque is required to be output, two or more star-shaped reduction gear sets can be rotated. Several gear sets are connected in series, so that large torque can be output, and bolts with different torques can be screwed.

Detailed Description
An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.
As shown in fig. 1 to 3, a hydraulic torque wrench provided in an embodiment of the present invention includes a vane hydraulic motor 1, a star-shaped reduction gear set 2, and an output shaft 3, wherein the vane hydraulic motor 1 is provided with a plurality of star-shaped reduction gear sets 2; the output end of the vane hydraulic motor 1 is connected with an output shaft 3.
Preferably, the output shaft 3 is a structure arranged along the axial direction of the output end of the vane hydraulic motor 1; the output shaft 3 is connected with the sleeve.
Preferably, a plurality of the planetary reduction gear sets 2 are connected in series.
Preferably, a rubber sleeve is mounted on the housing of the vane hydraulic motor 1.
The working principle is as follows: the output end of the vane hydraulic motor 1 can continuously rotate towards one direction, but the output end of the vane hydraulic motor 1 can continuously rotate towards one direction, compared with a piston torque on a traditional hydraulic torque motor, the star-shaped reduction gear set can amplify the output torque of the vane hydraulic motor 1, the output shaft 3 can be made into a directional structure, the output shaft 3 can be directly connected with a sleeve, the defects of a traditional hydraulic torque wrench are overcome, the vane hydraulic motor can continuously rotate towards one direction, in addition, the vane hydraulic motor can be conveniently taken down when a bolt is tightened, the star-shaped reduction gear set can be rotated according to different torque conditions, and if large torque needs to be output, two or more star-shaped reduction gear sets can be rotated. Several gear sets are connected in series, so that large torque can be output, and bolts with different torques can be screwed.
The above disclosure is only for the specific embodiment of the present invention, but the embodiment of the present invention is not limited thereto, and any variations that can be made by those skilled in the art should fall within the scope of the present invention.
