[0026] The bracket 8 includes a column 801 , the top of which is connected to the workbench 1 , the top of which is connected to a top plate 802 , the upper surface of which is connected to two vertical plates 803 , and a base 804 is connected between the tops of the two vertical plates 803 .

[0027] Among them, the elastic member 9 includes an upper spring sheet 901 and a lower spring; a notch is opened on the top plate 802, and the two ends of the lower spring sheet 902 are connected to the top plate 802 on both sides of the notch through two lower pressure blocks 903, and the support 401 at the top of the clamp 4 is connected to the center of the lower spring sheet 902.

[0028] Among them, two ear plates 805 are connected to the inner side of the vertical plate 803, the two ends of the upper spring sheet 901 are connected to the two ear plates 805 through the upper pressing block 904, and the top end of the support rod 5 is connected to the center of the upper spring sheet 901.

[0029] Among them, the eccentric component 6 includes an eccentric shaft 601, which is rotatably connected to the base 804. An eccentric hole 602 is provided at one end of the eccentric shaft 601, and the axial direction of the eccentric hole 602 deviates from the axis of the eccentric shaft 601 by 5 to 6 threads; a bearing 603 is interference fit in the eccentric hole 602, and a round rod 604 is connected to the center of the bearing 603, and one end of the round rod 604 extends to the outside of the eccentric hole 602.

[0030] One end of the connecting rod 7 is connected to the round rod 604 , and the other end is connected to the support 401 .

[0031] The driving device is a motor 10, a driving pulley is connected to the power output end of the motor 10, a driven pulley is connected to one end of the eccentric shaft 601, and a synchronous belt 1001 is connected between the driving pulley and the synchronous belt 1001 wheel.

[0032] Embodiment 2: This embodiment is a further improvement of Embodiment 1. The main improvement is that when Embodiment 1 is used, the bearing 603 has the risk of falling off. In this embodiment, the above defects can be avoided. Specifically:

[0033] There are two bearings 603 arranged in parallel, and a threaded hole 605 is provided on the eccentric shaft 601. The threaded hole 605 is connected to the eccentric hole 602. The backstop screw 606 is threadedly engaged in the threaded hole 605, and the backstop screw 606 extends between the two bearings 603.

[0034] Apart from this, this embodiment is exactly the same as Embodiment 1 and will not be described in detail here.

[0035] The specific working principle of the utility model is as follows:

[0036] During operation, the motor 10 drives the eccentric shaft 601 to rotate, and the outer ring of the bearing 603 at one end of the eccentric shaft 601 rotates while the inner ring does not rotate. Since the bearing 603 is installed in the eccentric hole 602, the round rod 604 connected to the inner ring of the bearing 603 will move up and down.

The measuring wire 11 clamped on the chuck 4 will also move up and down. The up and down movement of the measuring wire 11 can make the grinding paste slowly flow into the position to be processed during the processing, and the mold hole is ground by the grinding paste, thereby increasing the mold hole processing efficiency by about one time; at the same time, the mold 3 has less wear on the measuring wire 11 during the processing, and the measuring wire 11 does not need to be replaced frequently, thereby reducing the production cost.

[0037] At the same time, the speed of the motor 10 is adjustable. The faster the speed of the motor 10 is, the higher the movement frequency is, and the faster the processing is.

Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
