[0024] This specific embodiment is a telescopic torque chuck, the structural diagram of which is shown below. Figures 1-6 As shown, the torque chuck includes a circular mounting tube 1, an annular moving plate 2 is slidably connected to the outside of the circular mounting tube 1, a plurality of hydraulic cylinders 6 are fixed inside the circular mounting tube 1, the output end of the hydraulic cylinders 6 is fixedly connected to the annular moving plate 2, a chuck assembly 4 is rotatably connected to the outside of the annular moving plate 2, and a transverse rotating column 5 is fixed to the outside of the chuck assembly 4. The transverse rotating column 5 is located inside the circular mounting tube 1 and is rotatably connected to the circular mounting tube 1 through a bearing.

[0025] Multiple dovetail sliders are fixed inside the annular moving plate 2. The circular mounting tube 1 has a dovetail groove adapted to the dovetail slider inside. The annular moving plate 2 and the circular mounting tube 1 are slidably connected by the cooperation of the dovetail slider and the dovetail groove. By setting the cooperation of the dovetail slider and the dovetail groove, the annular moving plate 2 can slide laterally on the outside of the circular mounting tube 1.

[0026] The chuck assembly 4 is composed of a first circular part 41, a second circular part 42 and a circular slide tube 43. One end of the first circular part 41 is fixed to the circular slide tube 43, and the second circular part 42 is slidably connected to the outside of the circular slide tube 43. The inside of the first circular part 41 is provided with a moving component for moving the second circular part 42.

[0027] A transverse slider is fixed on the outside of the circular slide tube 43, and a transverse groove is provided inside the second circular part 42. The circular slide tube 43 and the second circular part 42 are slidably connected by the cooperation of the transverse slider and the transverse groove. By setting the transverse slider and the transverse groove, the circular slide tube 43 can move laterally inside the second circular part 42, and the second circular part 42 can move at one end of the first circular part 41.

[0028] Here, the operation of the hydraulic cylinder 6 enables the annular moving plate 2 to move laterally on the outside of the circular mounting tube 1. The movement of the annular moving plate 2 enables the clamping assembly 4 to rotate with the lateral rotating column 5 via the oblique rotating column 3, thereby enabling the clamping assembly 4 to clamp the object.

[0029] The moving component includes a circular rotating part 46, which has an internal hexagonal groove. The circular rotating part 46 is located inside the first circular part 41 and is rotatably connected to the first circular part 41 via a bearing. A circular rotating rod 45 is fixed to one end of the circular rotating part 46, and a transverse rotating rod 47 is fixed to one end of the circular rotating rod 45. A transverse cylinder 48 is threaded to the outer side of the transverse rotating rod 47. One end of the transverse cylinder 48 is slidably connected to the second circular part 42, and the transverse cylinder 48 is located inside the circular slide tube 43 and is slidably connected to the circular slide tube 43.

[0030] The circular slide tube 43 has a circular groove inside, and the transverse cylinder 48 is located inside the circular groove and is slidably connected to the circular groove. The circular groove allows the transverse cylinder 48 to move laterally inside the circular slide tube 43.

[0031] A circular sleeve 44 is fixed to the outside of the first circular part 41. The bottom of the circular sleeve 44 is rotatably connected to the inclined rotating column 3 through a pin. The transverse rotating column 5 is close to the side of the first circular part 41 and is welded to the first circular part 41, so that the first circular part 41 can rotate around the transverse rotating column 5 as the center.

[0032] Here, the internal hexagonal fitting allows the circular rotating part 46 to rotate inside the first circular part 41. The rotation of the circular rotating part 46 allows the circular rotating rod 45 to rotate inside the first circular part 41. The rotation of the circular rotating rod 45 allows the transverse rotating rod 47 to rotate. The rotation of the transverse rotating rod 47 allows the transverse cylinder 48 to slide inside, and allows the circular slide tube 43 to move inside the second circular part 42, thus enabling the second circular part 42 to move.

[0033] Working principle: When using the torque chuck of this technical solution, the operation of the hydraulic cylinder 6 enables the annular moving plate 2 to move laterally on the outside of the circular mounting tube 1. The movement of the annular moving plate 2 enables the chuck assembly 4 to rotate with the lateral rotating column 5 through the oblique rotating column 3, thereby enabling the chuck assembly 4 to clamp the object.

[0034] The hexagonal socket allows the circular rotating part 46 to rotate inside the first circular part 41. The rotation of the circular rotating part 46 allows the circular rotating rod 45 to rotate inside the first circular part 41. The rotation of the circular rotating rod 45 allows the transverse rotating rod 47 to rotate. The rotation of the transverse rotating rod 47 allows the transverse cylinder 48 to slide inside, and allows the circular slide tube 43 to move inside the second circular part 42. This allows the second circular part 42 to move, and by moving the second circular part 42, the clamping range of the second circular part 42 can be adjusted to accommodate objects of different diameters.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
