[0024] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0025] Reference Figures 1 to 4As shown, a core shaft pressing block module is provided, including a core shaft 1, one end of which is rotatably connected to two pressing blocks 2 via a first pin shaft 4, and both pressing blocks 2 are provided with a clamping portion 21 for clamping a workpiece and an assembly hole 22 for the first pin shaft 4 to slide, and the first pin shaft 4 is movably arranged in the assembly hole 22 so that the clamping portion 21 can be rotated and hidden in the core shaft 1 or rotated and protruded from the outside of the core shaft 1, and a movable connecting piece 3 is installed at the other end of the core shaft 1, and the connecting piece 3 is fixedly connected to the two pressing blocks 2.

[0026] In this embodiment, the workpiece is sleeved on the mandrel 1, and the connecting member 3 is provided with an interface 33, and the interface 33 is connected to an oil pump, and the oil pump enables the connecting member 3 to move back and forth on the mandrel 1. Figure 1 and Figure 3 As shown, when the connecting member 3 moves outward, since the connecting member 3 is fixedly connected to the two pressing blocks 2, the two pressing blocks 2 are driven to move outward, and the first pin 4 moves to the end of the assembly hole 22 close to the clamping portion 21. At this time, the clamping portion 21 protrudes out of the core shaft 1, and the two clamping portions 21 clamp the inner end surface of the workpiece and fix it without contacting its outer end surface, so that the outer end surface is not damaged; Figure 4 As shown, when the connecting member 3 moves into the core shaft 1, the first pin shaft 4 moves from one end of the assembly hole 22 to the other end, and the clamping portion 21 also changes from protruding outside the core shaft 1 to being hidden and retracted inside the core shaft 1, thereby achieving a loosening effect.

[0027] In one embodiment of the utility model, the assembly hole 22 is a V-shaped structure, one end of the assembly hole 22 is vertically set, and the other end is inclined. When the first pin shaft 4 slides along the trajectory of the assembly hole 22, the clamping portion 21 on the pressure block 2 will be hidden in the core shaft 1 or protrude from the outside of the core shaft 1. The assembly hole 22 is a V-shaped structure, which is more convenient for the pressure block 2 to rotate, and at the same time limits the rotation angle of the pressure block 2, so as to better clamp or release the workpiece.

[0028] In one embodiment of the utility model, a mounting hole 23 is provided at one end of the pressure block 2 away from the clamping portion 21, a through hole 31 is provided on the connecting member 3, the pressure block 2 is fixedly connected to the connecting member 3 through a second pin shaft 5, the second pin shaft 5 passes through the through hole 31 and the mounting hole 23, a first groove 32 is provided in the middle of the connecting member 3, the pressure block 2 is inserted into the first groove 32, and is fixedly connected to the connecting member 3 through the second pin shaft 5, the connecting member 3 is inserted into the core shaft 1, the pressure block 2 is inserted into the first groove 32 of the connecting member 3, and then the second pin shaft 5 passes through a through hole 31, two mounting holes 32 and another through hole 31 in sequence, thereby fixing the pressure block 2 and the connecting member 3, so that when the connecting member 3 moves, the pressure block 2 also moves accordingly.

[0029] Furthermore, a connecting hole 11 adapted to the connecting member 3 is opened at one end of the core shaft 1 close to the connecting member 3, and the connecting member 3 is movably arranged in the connecting hole 11. A second notch 12 for facilitating the insertion of the second pin 5 is arranged on one side of the connecting hole 11. The second notch 12 is arranged at one end of the core shaft 1 close to the connecting member 3. The connecting member 3 is installed in the connecting hole 11 and can move back and forth to drive the pressure block 2 to move. In order to facilitate the fixed connection of the second pin 5 with the pressure block 2 and the connecting member 3, the second notch 12 is arranged to facilitate the insertion or removal of the second pin 5 and facilitate subsequent daily maintenance.

[0030] A third groove 13 is provided at one end of the core shaft 1 away from the connecting member 3, and the third groove 13 is connected to the connecting hole 11. The two pressure blocks 2 are rotatably set in the third groove 13. A circular hole adapted to the first pin shaft 4 is provided on the core shaft 1. The first pin shaft 4 passes through the circular hole and is connected to the assembly hole 22 of the pressure block 2. Therefore, the position of the first pin shaft 4 on the core shaft 1 is fixed. It is the connecting member 3 that drives the pressure block 2 to move, and the first pin shaft 4 slides on the assembly hole 22. The third groove 13 is connected to the connecting hole 11, so that the pressure block 2 can be inserted into the connecting hole 11 and fixedly connected to the connecting member 3.

[0031] In one embodiment of the utility model, the two pressure blocks 2 are L-shaped structures, and the two clamping parts 21 are relatively arranged on the core shaft 1, that is, the two clamping parts 21 are arranged in opposite directions, respectively clamping the inner end faces of the workpieces. The relative direction arrangement is conducive to locking the workpieces more firmly. When rotating and closing, they are also rotated and closed in the third groove 13 in the relative directions.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
