[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0019] The embodiment of the utility model comprises a driving mechanism 1, a transplanting fixture 9 and a tensioning tool. The tensioning tool comprises a main shaft 2, a pull rod 4, a locking nut 5, a gasket 6, an elastic body 8, a locking sheet 7 and a locking shaft 10.

[0020] The spindle 2 plays the role of tightening the workpiece 3, docking the transplanting fixture 9, and docking the driving mechanism 1. The left end of the spindle 2 is the driving end, which is provided with a spindle driving section 21. The spindle driving section 21 is the interface connecting the tightening fixture and the driving mechanism 1. The driving mechanism 1 is used to cooperate with the spindle driving section 21 and provide rotational power. After the tightening fixture is transplanted into place, the driving mechanism 1 translates and connects with the spindle driving section 21, driving the spindle 2 to rotate, and then driving the workpiece 3 to rotate. The right end of the spindle 2 is the tightening end, which is used to install the workpiece 3. The workpiece 3 is the object of tightening, transplanting and rotating of this mechanism.

[0021] The diameter of the right half of the spindle 2 is reduced so that it can penetrate deeper into the workpiece 3, preventing the locking plate 7 and the engaging surface of the workpiece 3 from being too close to the outside, which would cause the workpiece to be easily deformed.

[0022] The locking piece 7 is installed at the tensioning end of the main shaft 2. The left and right ends of the locking piece 7 are both provided with locking piece inclined surfaces 71.

[0023] The tightening end of the main shaft 2 is provided with a main shaft inclined surface 21, and the locking piece inclined surface 71 at the left end of the locking piece 7 is connected to the main shaft inclined surface 21. The locking piece 7 is used to squeeze and tighten the workpiece 3. The locking piece 7 can be 2 pieces or multiple pieces.

[0024] The pull rod 4 is movably installed in the main shaft 2, one end of which is connected to the locking nut 5, and the other end is connected to the locking shaft 10. The locking shaft 10 is provided with a locking shaft inclined surface 101. The locking plate inclined surface 71 at the right end of the locking plate 7 is connected to the locking shaft inclined surface 101. The locking plate inclined surface 71 cooperates with the main shaft inclined surface 21 and the locking shaft inclined surface 101, so that the locking plate 7 can slide on the main shaft 2, and then lock the workpiece 3. Through the cooperation of the locking plate inclined surface 71 and the locking shaft inclined surface 101, the locking workpiece is more reliable. The pull rod 4 is used to tighten and expand the locking plate 7, so that the locking plate 7 squeezes and fixes the workpiece 3. The locking nut 5 is used to rotate and drive the pull rod 4 to move left, and then lock the workpiece 3 through the locking plate 7. The locking plate 7 can be 2 pieces or multiple pieces.

[0025] The washer 6 is installed between the locking nut 5 and the main shaft 2 to prevent the nut 5 from loosening.

[0026] The elastic body 8 is installed on the locking piece 7 to constrain the locking piece 7 so that the locking piece 7 shrinks inward to prevent the locking piece 7 from falling when the workpiece is taken out. The elastic body 8 can be in the form of an O-ring, a rubber band, etc.

[0027] The main shaft 2 is provided with a main shaft transplanting section 22 , which is an interface connected to the transplanting fixture 9 , and a locking hole 221 is provided on the main shaft transplanting section 22 .

[0028] The transplanting fixture 9 is fixed on a manipulator or other translation mechanism to drive the tensioning tool to move. The transplanting fixture 9 is provided with a locking mechanism 11, which is used to lock the tensioning tool during the transplanting process to prevent the workpiece from slipping and being damaged during the movement. The locking mechanism 11 includes a locking cylinder 111 and a locking shaft 112, the locking cylinder 111 is connected to the locking shaft 112, and the locking shaft 112 cooperates with the locking hole 221.

[0029] The working principle of the utility model is as follows:

[0030] Sleeve one end of the cylindrical inner hole of the workpiece 3 on the locking plate 7, tighten the locking nut 5, move the pull rod 4 to the left, drive the locking plate 7 to move to the left and outward, and the locking plate 7 is squeezed and fixed to the inside of the workpiece 3.

[0031] After the locking is completed, the transplanting fixture 9 clamps the main shaft transplanting section 22, and moves the tensioning tool to each process section. During the transplanting process, the locking cylinder 111 drives the locking shaft 112 to insert into the locking hole 221. After the tensioning tool is in place at the process section, the driving mechanism 1 moves and connects with the main shaft driving section 21, driving the tensioning tool to rotate, and then driving the workpiece 3 to rotate.

[0032] After the process is completed, the locking nut 5 is loosened to move the pull rod 4 to the right, driving the locking plate 7 to move to the right to disengage from the inner surface of the workpiece 3, and the workpiece 3 is taken out.

[0033] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
