Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

As shown in the figure, the utility model discloses a fixing device for a hydraulic wrench when torque is applied, which comprises a flange clamping device 1 and a reaction force arm clamping device 2, wherein the flange clamping device 1 comprises a clamping plate I3 and a clamping plate II 4, the reaction force arm clamping device 2 comprises a clamping plate III 5 and a clamping plate IV 6, one side of the clamping plate I3 facing the clamping plate II 4 is provided with 2 guide grooves I, one side of the clamping plate II 4 facing the clamping plate I3 is provided with a guide post I7 corresponding to the guide grooves I, one side of the clamping plate II 4 is provided with a stud I8, the shaft of the stud I8 is parallel to the guide post I7, the stud I8 is positioned between the 2 guide posts I7, and the stud I8 is connected with the clamping plate I3; the back of the clamping plate II 4 is provided with a clamping plate III 5, the lower end of the clamping plate III 5 is provided with 2 guide grooves II, the lower end of the clamping plate IV 6 is provided with 2 guide posts II 9 corresponding to the guide grooves II, one side of the clamping plate IV 6 is provided with a stud II 10, the stud II 10 is positioned between the 2 guide posts II 9, and the stud II 10 is connected with the clamping plate III 5. The reaction force arm clamping device is used for clamping the reaction force arm, and the flange clamping device is used for clamping the flange. When the reaction force arm and the flange are clamped, the hydraulic head is adjusted to enable the sleeve to be aligned with the bolt, and torque is applied. The flange clamping device is loosened, the position of the flange is adjusted, and the clamp is clamped again, so that the flange clamping device can be used for fastening or disassembling other bolts.

The clamping principle is to rotate the stud, and the distance between the clamping plate I and the clamping plate II is close, and the distance between the clamping plate III and the clamping plate IV is close through the screw principle. The above clamping principle is a conventional mechanism and will not be described in detail again.
