Description

Technical Field

[0001] The utility model relates to the technical field of saw blade processing, in particular to a high-precision locking device used for circular saw blade processing. Background Art

[0002] The processing of circular saw blades includes a side grinding process. During this process, the circular saw blade needs to be clamped on both sides. The traditional clamping method is to place the circular saw blade between the inner flange and the outer flange, and then manually twist the outer nut of the outer flange until the outer flange and the inner flange are tightly fitted to the circular saw blade. This method is not only time-consuming and labor-intensive, but it is also difficult to determine whether the circular saw blade is completely clamped. If it is not clamped, unexpected situations such as shaking and offset will occur during the side grinding process, and the circular saw blade will be scrapped. Based on this situation, how to ensure that the circular saw blade is completely clamped during the side grinding process to avoid scrapping and ensure grinding accuracy is becoming an increasingly urgent problem that relevant technical personnel need to solve.

[0026] Furthermore, the pulling claw includes a connecting rod 19, and the connecting rod 19 is fixedly connected to the tensioning rod 17 at one end close to the tensioning rod 17. A grab plate 20 is equidistantly arranged in a ring shape at one end of the connecting rod 19 away from the tensioning rod 17. The grab plate 20 is arranged in an arc groove 21 near one end of the connecting rod 19, and a spring is arranged inside the arc groove 21, and the spring is in the shape of a circular ring.

[0028] Furthermore, a bearing 12 is fixedly arranged inside the fixed seat 4, and the rotating shaft 16 is fixedly connected to the inner ring of the bearing 12. The number of the bearings 12 is 2 groups, and an outer spacer sleeve 13 is arranged between the 2 groups of bearings 12. An inner spacer sleeve 15 is arranged inside the outer spacer sleeve 13. A locking spacer sleeve 18 is arranged inside the fixed seat 4 close to the rotating hydraulic cylinder 1.

During this process, the end of the rivet 6 passes through the center hole 10 and finally stays inside the claw, that is, between the grab plates 20, and the rotating hydraulic cylinder 1 is started, and the output end of the rotating hydraulic cylinder 1 pulls the tension rod 17 toward the rotating hydraulic The cylinder 1 translates in the direction of the pull rivet 6. During this process, the limit of the rotating shaft 16 causes the grab plate 20 to gather and "grasp" the end of the rivet 6, and then the claw drives the rivet 6, the clamping plate 7, and the circular saw blade to translate as a whole toward the flange 8, until the clamping plate 7 and the flange 8 cooperate to clamp the circular saw blade. The rotating hydraulic cylinder 1 continuously applies a pulling force to the rivet 6, so that the circular saw blade is always kept in a clamped state, and the rotating shaft 16 is driven to rotate by an external device. The clamped circular saw blade rotates synchronously with the rotating shaft 16. At this time, the side grinding process of the circular saw blade can be performed through the supporting equipment.
