The connecting block 8 is fixedly connected to the end face of the movable plate 4 close to the fixed plate 3. The connection between the two is bolted, integrally connected, or welded. In this embodiment, the connection block 8 and the movable plate 4 are connected in an integral manner. A through hole is provided on the connecting block 8 for the lead screw 5 to pass through.

[0026] The above is a basic implementation of the present invention, which can be further improved, optimized and limited to obtain the following embodiments:

[0027] Example 2

[0028] This embodiment is an improved scheme of the automatic adjustment mechanism of the center height of the Fancheng grinding head 1 made on the basis of the embodiment 1. Its main structure is the same as that of the embodiment 1. The improvement is that the movable plate 4 is connected to the screw 5 through the connecting block 8. The grinding head 1 receives a large force during operation. It is difficult to achieve locking by only relying on the internal thread on the connecting block 8 and the screw 5, which affects the grinding effect. Therefore, Figure 2 As shown, a locking unit is provided on the movable plate 4, and the locking unit includes a hydraulic locking cylinder 7 fixedly connected to the movable plate 4. In this embodiment, the outer shell of the hydraulic locking cylinder 7 is connected to the movable plate 4 by bolts, and a locking screw 9 is provided on the hydraulic locking cylinder 7. Supplying oil and cutting off oil to the hydraulic locking cylinder 7 can drive the locking screw 9 to separate and connect with the fixed plate 3.

[0029] The fixed plate 3 is provided with a locking block 304, and the locking block 304 is provided with a stepped groove 305 extending along the moving direction of the movable plate 4. The extending direction of the stepped groove 305 is parallel to the length direction of the screw 5. Figure 2 As shown, the stepped groove 305 includes a first slide groove and a second slide groove that are interconnected. The width of the first slide groove is greater than the width of the second slide groove. The head of the locking screw 9 is located in the first slide groove, and there is a clearance margin between the left end face of the head of the locking screw 9 and the bottom of the second slide groove for the locking screw 9 to move. The tail of the locking screw 9 passes through the second slide groove and is connected to the hydraulic locking cylinder 7. When the Fan Cheng grinding head 1 needs to be adjusted, oil is supplied to the hydraulic locking cylinder 7 so that it pushes the locking screw 9 to move in the direction away from the hydraulic locking cylinder 7, that is, the head of the locking screw 9 moves toward the bottom of the second slide groove. At this time, the right side of the head of the locking screw 9 is separated from the side wall of the second slide groove, and the locking screw 9 is separated from the locking block 304. The drive motor 6 drives the screw 5 to rotate and drive the movable plate 4 to move. At this time, the hydraulic locking cylinder 7 and the locking screw 9 move with the movable plate 4, and the head of the locking screw 9 is in the first slide groove. The tail of the locking screw 9 slides along the second slide groove; when the Fan Cheng grinding head 1 needs to be locked, the oil to the hydraulic locking cylinder 7 is cut off, so that it pulls the locking screw 9 to move toward the hydraulic locking cylinder 7, that is, the head of the locking screw 9 moves toward the first slide groove until the right end face of the locking screw 9 conflicts with the side wall of the second slide groove, that is, the head of the locking screw 9 is pressed against the inner wall of the second slide groove, realizing the connection between the locking screw 9 and the locking block 304, and then realizing the locking of the Fan Cheng grinding head 1, thereby improving the grinding effect.
