The two locking screw rings 109 are threaded to the cutter shaft 106 and are located at the tail of the hollow rotating shaft 105. The rear side of the hollow rotating shaft 105 is provided with a stepped external toothed part 113 that meshes with the gear 110 to achieve transmission. The drive motor 111 is mounted on the frame 104 and its output end is fixedly connected to the gear 110. The frame 104 is fixed by positioning pins and bolts, and a bearing seat is integrally provided on its front end. The rectangular connecting part at the bottom of the slide 103 is connected to the output end of the servo cylinder 112 by bolts. The hollow rotating shaft 105 is mounted on the bearing seat by a rotating bearing. A rectangular groove is provided in the annular part of the front through hole to cooperate with the positioning block 108. The positioning block 108 prevents the cutter shaft 106 from rotating after installation. The tail of the cutter shaft 106 is provided with a stepped external thread end to facilitate the installation and fixation of the locking screw ring 109.

The hollow rotating shaft 105 has a front spacer ring on the front side, which abuts against the inner ring of the bearing, and a limiting disc abuts against the front spacer ring. The rear side has a stepped external thread end, which facilitates the cooperation of the limiting thread ring and the rear spacer ring to abut against the inner ring on the other side of the bearing. The outer rings of the front and rear bearings are both limited by bearing end caps, which are fixed by countersunk bolts.

The hydraulic cylinder 117 is fixed by bolts from bottom to top, and a disc is fixed to its output end by countersunk bolts. The disc is connected to the clamping plate 116 by bolts. The guide rods 118 are symmetrically arranged on the clamping plate 116, and the guide rods 118 directly slide in cooperation with the T-shaped linear sliding bearings (not shown in the figure) on the mounting plate 115.

[0024] This invention addresses the problem of inconvenience for operators when replacing circular saw blades in existing equipment, which reduces replacement efficiency and makes processing inconvenient. First, the workpiece is clamped and fixed at both ends by the workpiece fixing mechanism. Then, the drive motor 111 is activated to rotate the gear 110. The rotation of the gear 110 drives the stepped external toothed portion 113 to rotate, thereby rotating the hollow rotating shaft 105. Finally, the cutter shaft 106 rotates, driving the cutting blade 107 to rotate. Finally, the servo cylinder 112 pushes the cutting blade 107 to move linearly for cutting. When the cutting blade 107 needs to be replaced, the two locking screws 109 are removed first, and then the cutting blade 107 and cutter shaft 106 are removed as a whole for replacement. This convenient and quick solution solves the problem of inconvenience for operators when replacing circular saw blades in existing equipment, which reduces replacement efficiency and makes processing inconvenient.

The length of the top plate 201 ensures that the servo cylinder 112 can be covered when the slide block 103 moves forward or backward to its maximum position.
