In addition, the components of the chuck 100 are compact in structure and small in overall size, and can meet the application requirements in a limited space.
Referring to fig. 4, when the chuck 100 is in an initial state (hereinafter referred to as a "first state"), the plurality of clamping jaws 42 are separated from each other, the rotating body 20 rotates in a first direction (i.e., counterclockwise) and drives the ends of the plurality of rotating arms 40 to rotate therewith, and meanwhile, the limiting posts 311 slide along the limiting grooves 41 on the rotating arms 40, so that the clamping jaws 42 approach each other. In addition, the elastic component 50 is elastically deformed by the relative movement of the rotating body 20 and the connecting body 30, referring to fig. 5, the annular workpiece 200 is sleeved on the clamping jaws 42, and the elastic restoring force of the elastic component 50 causes the rotating body 20 to rotate in the second direction (i.e., clockwise direction) and drives the clamping jaws 42 to move away from each other until the inner circumference of the annular workpiece 200 is tightly supported.
Referring to fig. 6, when the clamping jaws 42 are in a gathered state (hereinafter referred to as a "second state"), the rotating body 20 rotates in a second direction to drive the ends of the rotating arms 40 to rotate, and at the same time, the limiting posts 311 slide along the limiting grooves 41 on the rotating arms 40 to separate the clamping jaws 42 from each other. Referring to fig. 7, the annular workpiece 200 is disposed between the clamping jaws 42, and the elastic restoring force of the elastic component 50 causes the rotating body 20 to rotate in a first direction and drives the clamping jaws 42 to approach each other until the outer circumference of the annular workpiece 200 is clamped.
Please refer to fig. 2, the first bearing 24 is installed on the inner wall of the through hole 21 of the rotating body 20, and the engaging portion 32 penetrates through the first bearing 24.

Referring to fig. 8, the end of the fixing base 10 away from the connecting body 30 is provided with a positioning slot 11 and a plurality of magnet blocks 12 for assembling the chuck 100 with the rotating table. The rotary table drives the chuck 100 to integrally rotate, so that the annular workpiece 200 clamped on the chuck 100 can be conveniently processed. Alternatively, a plurality of threaded holes may be formed at the end of the fixing base 10, and the chuck 100 may be integrally assembled to the rotary table by screws.
A plurality of mounting holes 13 are opened on the bottom wall of the positioning groove 11, and a plurality of connectors 300 penetrate through the mounting holes 13 and are connected to the matching portion 32.
Referring to fig. 4 and 9, the rotating body 20 is provided with a groove 22, and the main body 31 is accommodated in the groove 22, so that the surface of the main body 31 is flush with the periphery of the rotating body 20 to avoid obstructing the rotation of the rotating arm 40. Meanwhile, the limiting column 311 arranged on the main body 31 is conveniently matched with the limiting groove 41 formed on the rotating arm 40.
Further, the bottom wall of the groove 22 is provided with a through hole 21 and an avoiding groove 23. Since the space between the rotating body 20 and the connecting body 30 is not enough to arrange the elastic component 50, the elastic component 50 is arranged on the side of the rotating body 20 away from the connecting body 30, and the arrangement of the avoiding groove 23 facilitates the connection of the elastic component 50 and the connecting body 30.
Referring to fig. 3, the elastic component 50 is located on one side of the rotating body 20 close to the fixing base 10, the elastic component 50 includes a first supporting column 51, a second supporting column 52 and an elastic member 53 disposed between the first supporting column 51 and the second supporting column 52, the first supporting column 51 is connected to the rotating body 20, the rotating body 20 is provided with an avoiding groove 23, and the second supporting column 52 penetrates through the avoiding groove 23 and is connected to the connecting body 30.
It will be appreciated that when the rotating body 20 rotates, the trajectory of the second supporting column 52 with respect to the rotating body 20 is a circular arc, and thus the avoiding groove 23 is designed to be a circular arc.
In one embodiment, the number of the elastic elements 50 is 2, and the two elastic elements 50 are disposed in central symmetry with respect to the center of the rotating body 20, and correspondingly, the number of the avoiding grooves 23 is 2.

The end of each rotating arm 40 is bent to extend a connecting column 43, and each connecting column 43 penetrates one of the running rails 61 and is connected to the clamping jaw 42.
When the chuck 100 is in the initial state, the elastic component 50 has an elastic restoring force, that is, when the chuck 100 is assembled, the elastic component 50 is elastically deformed to a certain extent, the rotating body 20 and the connecting body 30 tend to move relatively, and each connecting column 43 is located at the end of the corresponding running track 62. The positioning plate 60 prevents the relative movement between the rotating body 20 and the connecting body 30, so that the clamping jaws 42 are kept stationary, thereby preventing the relative movement of the clamping jaws 42 when the chuck 100 is in an inoperative state.
In one embodiment, the number of the rotating arms 40 is 3, correspondingly, the number of the clamping jaws 42 is also 3, and the number of the running tracks 61 on the placing plate 60 is also 3, and every 2 running tracks form an included angle of 120 °.
The distance between the clamping jaw 42 and the rotating arm 40 is larger than the thickness of the placing plate 60, so that a gap is formed between the placing plate 60 and the clamping jaw 42, the placing plate 60 can rotate freely, the moving track 61 on the placing plate 60 cannot block the movement of the clamping jaw 42, and the rotating arm 40 is prevented from being blocked from rotating.
Referring to fig. 13, the chuck 100 further includes a cover plate 70 disposed on the rotating body 20, the cover plate 70 is opened with an escape opening, the cover plate 70 is covered on the placing plate 60, and the clamping jaws 42 are exposed from the escape opening. By providing the cover plate 70, when the holding jaw 42 and the rotating arm 40 are loosened, the placing plate 60 is shielded by the cover plate 70 and does not come off.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
