Description

The circular sawing machine at adjustable saw sheet angle of inclination

The utility model relates to a kind of saw cutting device, relates to a kind of circular sawing machine of adjustable saw sheet inclined cut angle or rather, can do the multiple angles adjustment when the side direction cut workpiece.

Saw cutting devices such as various scroll saw machines, circular sawing machine all are facility commonly used in the timber work.The circular sawing machine structure that tradition is used as shown in Figure 1, set firmly a supporting seat 2 in the rear end of base 1, in the top of the supporting seat 2 one cutting elements such as leader 3 and saw blade that are pivoted, in this base 1 upper end one rotating workbench (end illustrates among the figure) and striker plate 4 is set in addition, adjusts vertical cutting angle of workpiece on the workbench by turn adjusting handle 5.Though this circular sawing machine can be adjusted the ripping angle of workpiece by rotary table, but can not the lateral tilt cut workpiece, promptly because the structural design of handle 3 and 2 no side direction of supporting seat (laterally) turn, therefore its supporting seat 2 only can provide vertically vertical dissection with the rotating shaft of 3 of handles, extremely inconvenient in the use, improved necessity is arranged in fact.

The purpose of this utility model is the circular sawing machine at a kind of adjustable saw sheet of design angle of inclination, but the gradient of multi-angle adjustment saw blade is come the side direction cut workpiece.

The purpose of this utility model is achieved in that the circular sawing machine at adjustable saw sheet angle of inclination, comprises base, is installed in rotatable discoid workbench, supporting seat, saw blade and handle on the base, it is characterized in that:

The rear end of described discoid workbench is equipped with two screws, by the solid described supporting seat of two screw spiral shells; Described supporting seat is the pedestal of semicircle arcuation, is equipped with horizontal axis hole in the central position of supporting seat root edge, is equipped with locking hole on the support pedestal of axis hole top, and the dorsal part two ends of supporting seat extend the block end with inclined-plane respectively; Also include rotating part, the rotating part bottom is provided with arc groove hole, the rotating part front end is provided with horizontal axis hole, there is a bolt one pivot to connect the horizontal axis hole and the rotating part of supporting seat, the arc groove hole that has the locking bolt to pass the locking hole of supporting seat and rotating part is positioned at the rotating part locking and supports on the pedestal, the bolt of rotating part two side ends pushes up the block end of the supporting seat two side ends of pulling, and has a bolt to pass the horizontal axis hole of rotating part front end and the axle pivot end one pivot joint handle and the rotating part of handle.

The block end of supporting seat dorsal part end is as the top of the rotating part two side ends bolt block of pulling, make it suitably to adjust required lateral tilt cutting angle, arc groove hole on the rotating part then provides side direction turn scope for rotating part, the handle and the saw blade thereof that are articulated on the rotating part by the axle bolt are axis of rotation with the axle bolt, reach the purpose of multi-angle adjustment and side direction cut workpiece.

Further specify technology of the present utility model below in conjunction with embodiment and accompanying drawing

Referring to Fig. 2, Fig. 3, the circular sawing machine at adjustable saw sheet angle of inclination mainly comprises base 10, rotatable discoid workbench 11, supporting seat 20, rotating part 30, saw blade 42 and handle 40.

Rotatable workbench 11 is installed on the base 10, and it is solid on workbench 11 with supporting seat 20 spiral shells by screw 12 that the rear end of this discoid workbench 11 is equipped with two screws, 12, two screws 22.Supporting seat 20 is pedestals of semicircle arcuation, is equipped with horizontal axis hole 23 in the root edge central position of supporting seat 20, and axle bolt 33 articulates supporting seat 20 and is integral with rotating part 30.Also be equipped with locking hole 24 in addition on the supporting seat 20 of axis hole 23 tops, locking bolt 34 is positioned at rotating part 30 lockings by locking hole 24 and supports on the pedestal 20.The dorsal part two ends of supporting seat 20 extend the block end 26 with inclined plane respectively, the top that rotates about as rotating part 30 two side ends bolts 36 block of pulling.Rotating part 30 bottoms are provided with arc groove hole 35, and for wearing locking bolt 34, the both side edges of arc groove hole 35 provides side direction turn scope for rotating part 30.Rotating part 30 front ends have horizontal axis hole 38, and axle bolt 48 passes the axle pivot end 41 that these horizontal axis hole 38 one articulate handle 40, and promptly handle 40 and saw blade 42 thereof can be that vertical perpendicular cuts operation is carried out in the axle center with axle bolt 48.

Referring to Fig. 4, the operational circumstances of circular sawing machine shown in the figure when adjusting saw blade inclined cut angle.When wanting vertical sawing workpieces, adjust locking bolt 34, make its aligning and be locked in the middle position of rotating part 30 arc groove holes 35, this moment handle 40 and 42 one-tenth vertical vertical cut states of saw blade.In the time will making 45 ° of saw blade 42 inclinations with cut workpiece, can unscrew locking bolt 34 earlier, again and then adjust two bolts 36 and the top of supporting seat 20 block ends 26 spacing of pulling, then can suitably adjust required lateral tilt cutting angle, screw locking bolt 34 at last, can realize the purpose of design of multi-angle adjustment side direction cut workpiece.

Circular sawing machine of the present utility model is supporting between the axle pivot end of pedestal and handle by a pivotally connected rotating part, again by adjusting the angle that locks bolt and can suitably adjust required side direction cut workpiece.
