[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this anti-vibration thread grinding machine includes a grinding machine body 1, a headstock 2, a motor 3 that drives the headstock 2 to rotate, and a worktable 4. The motor 3 is installed on one side of the worktable 4, and a mounting platform 5 is provided on the other side of the worktable 4. A mounting frame 6 is provided above the mounting platform 5. Several fixing frames 7 for reinforcing the mounting frame 6 are provided between the mounting frame 6 and the mounting platform 5. One end of the fixing frame 7 is connected to the edge of the mounting platform 5, and the other end is connected to the bottom of the mounting frame 6.
[0022] The mounting bracket 6 has a slot 8, a bearing 9 is installed in the slot 8, a rotating shaft 10 is installed in the bearing 9, and a top cone 11 is installed on the rotating shaft 10 to cooperate with the head frame 2 to clamp the workpiece.
[0023] A cylindrical linkage frame 12 is provided between the top cone 11 and the rotating shaft 10. A telescopic groove 13 is provided on the linkage frame 12. A connecting rod 14 is provided on the top cone 11 to cooperate with the telescopic groove 13 and to move within the telescopic groove 13. A limiting part 15 is provided between the connecting rod 14 and the telescopic groove 13 to limit each other.
[0024] The linkage frame 12 is provided with four mounting slots 16, all of which are connected to the telescopic slots 13. Mounting rods 17 are provided in the mounting slots 16, and the mounting rods 17 are provided with chucks 18 for clamping the workpiece. One end of the chucks 18 extends to the outside of the top cone 11, and the other end extends into the telescopic slots 13, and is provided with abutment parts 19.
[0025] The limiting part 15 located on the connecting rod 14 is provided with a mating part 20 for cooperating with the abutment part 19.
[0026] During use, the headstock 2 first holds one end of the workpiece in place. Then, the other end of the workpiece is slotted to mate with the top cone 11. After mates with the top cone 11, the moving component on the main body 1 of the conventional grinding machine causes the top cone 11 and the workpiece to press against each other. This causes the workpiece to move the connecting rod 14 into the telescopic channel 13. During the movement of the connecting rod 14, the mating part 20 contacts the abutting part 19. As the connecting rod 14 continues to move, the mating part 20 pushes the abutting part 19, causing the chuck 18 to rotate via the mounting rod 17 until the chuck 18 clamps the workpiece. At this point, the chuck 18 can no longer rotate, and the connecting rod 14 can no longer move. This indicates that the workpiece has been clamped.
[0027] To elaborate further, spring frames 21 are provided at the bottom of both the connecting rod 14 and the telescopic channel 13, and elastic elements 22 are provided between the spring frames 21. The two ends of the elastic elements 22 are connected to the spring frames 21 on the connecting rod 14 and the telescopic channel 13, respectively. When the workpiece needs to be removed, the top cone 11 is continuously disengaged from the workpiece by the moving component on the grinding machine body 1, and the elastic element is reset, so that the mating part 20 and the abutment part 19 are separated.
[0028] To elaborate further, the four mounting channels 16 are all located at the four equal divisions of the linkage frame 12.
[0029] To elaborate further, the front end of the chuck 18 is provided with an anti-slip surface 23 to increase friction.
[0030] To elaborate further, the abutment 19 extends to the outside of the elastic element 22 to prevent the abutment 19 from interfering with the elastic element 22 during rotation.
[0031] To elaborate further, a connecting shaft 24 is provided between the mounting rod 17 and the clamp 18.
[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0033] Although this document frequently uses terms such as grinding machine body 1, headstock 2, motor 3, worktable 4, mounting table 5, mounting bracket 6, fixing bracket 7, slot 8, bearing 9, rotating shaft 10, top cone 11, linkage bracket 12, telescopic channel 13, connecting rod 14, limiting part 15, mounting channel 16, mounting rod 17, chuck 18, abutment part 19, mating part 20, spring frame 21, elastic element 22, anti-slip surface 23, and connecting shaft 24, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
