Description
Technical Field
The utility model relates to a wood cutting technical field, especially a bench saw that both can be used for parallel cut and can be used for the angle cutting and dual-purpose cutting of double entry saw lean on bars device.
Background
A table saw or compound saw is a classic woodworking type electric tool and is widely used in furniture manufacturing and building decoration. In order to machine a high-precision workpiece by using a table saw or a compound saw, the precision of a fence is an essential important condition in addition to the requirement of high precision of the machine itself. The precision of the fence is mainly embodied in the perpendicularity of the fence support surface and the working table surface of the machine, the angle relative to the main plane of the saw blade and the stability of the combination of the fence body and the machine. For some larger machines, two kinds of backup grids are generally arranged, one is a straight-edge backup grid for parallel cutting, and the workpiece support surface of the backup grid is parallel to the main plane of a saw blade; the other is an angle rest fence used for cutting a certain angle for a workpiece, and the angle of the workpiece support surface relative to the main plane of the saw blade can be adjusted and locked according to the angle of the workpiece to be cut.
For some smaller machines, especially compound saws, only one dual-purpose angle fence device is usually matched, when parallel cutting is carried out, the angle fence is adjusted to be 0 degree or 90 degrees (different according to different scale marks of an angle scale), a fence supporting surface can be parallel to the main plane of a saw blade, and parallel cutting can also be carried out after locking. However, the use method of the fence has great difference between the parallel cutting and the angle cutting, so the specific requirements of the fence are completely different.
When the workpiece is cut in parallel, the leaning grid is fixed on a workbench of the machine and does not move, one surface of the workpiece is abutted against a supporting surface of the leaning grid and pushed from the workbench to the direction of the saw blade rotating at high speed, and the saw blade can cut the workpiece contacted with the workpiece. Since the support surface of the fence is parallel to the main plane of the saw blade, the workpiece surface cut by the saw blade is parallel to the contact surface of the workpiece. In addition to requiring high precision in the machine and fence, a secure lock of the fence to the machine is essential to cut a high quality parallel surface.
When the workpiece is subjected to angle cutting, one surface of the workpiece is abutted against the angle adjusting leaning grid supporting surface, and is pushed to the direction of the saw blade rotating at high speed along the guide groove on the workbench together with the angle leaning grid, and the saw blade cuts the workpiece contacted with the angle adjusting leaning grid. This state of cutting does not require a locking relationship between the fence and the machine.
In the dual-purpose angle fence device in the prior art, the role of strictly distinguishing the dual-purpose angle fence in two working states is mostly ignored, the angle seat positioning hole and the locking screw hole are simply overlapped and designed on the aluminum guide rail with the thickness of only a few millimeters, so that the problems of inaccurate angle positioning or insufficient locking force or even incapability of locking due to sliding wires often occur, and the problems of large abrasion and short service life are solved.
