[0008]

【Example】

 As shown in FIG. 1, the present invention is fixed to the side of the frame (1) of the workbench and combined with the original equipment and structure of the workbench to grasp the workpiece (4) more firmly and in multiple directions. be able to.

The structure of the workbench roughly includes two flat bases (12) corresponding to each other on the upper surface of the frame (1), and a turning device is provided between the lower surface of each flat base (12) and the frame (1). They are connected in (13). The tilting angle of the flat base (12) can be adjusted by the turning device (13). Since the structure of the turning device (13) is a well-known technique, detailed description thereof is omitted here. The corresponding two flat bases (12) can be moved relative to each other by rotating a handle (11) provided on the side surface of the frame (1). The adjusting principle is in the transmission screw (not shown in the figure) provided in the frame (1), and the transmission screw is combined with the screw hole provided in the lower part of the flat base (12) to rotate the handle (11). The transmission screw is rotated so as to approach or leave the flat base (12) relatively. Since this part is not the focus of the present invention, further explanation is omitted.

2 and 3 show a comparatively preferred embodiment of the work piece fitting of the present invention. In this embodiment, one flat rod (2) is provided and the lower end of the rod (2) is fixed to one side surface of the frame (1) with a bolt. Further, one claw seat (3) is provided, a coupling hole (34) through which the rod (2) can pass is provided at one end of the claw seat (3), and two side plates (33) parallel to each other are provided at the other end. To form. Each side plate (33) is provided with a connecting hole, and is further provided with one U-shaped pawl (31) and one convex ring (32) extending to form a handle (321). The convex ring (32) is provided with an eccentric hole, the convex ring (32) is placed between the two side plates (33), and the claw seat (32) sandwiching the convex ring (32) in the U-shaped pawl (31) ( Place the side plate (33) of 3). Two slots (310) are provided on two side walls of the U-shaped pawl (31), and the pin (311) is provided with the slot (310) of the U-shaped pawl (31) and the side plate (33) of the pawl seat (3). , And the convex ring (32) are inserted into and connected to each other, and at the same time, the inner bottom surface of the U-shaped pawl (31) is pressed against the ring surface of the convex ring (32). A slight V-shaped groove is provided on the outer bottom surface of the U-shaped pawl (31) so that the workpiece (4) can be stably gripped.

As shown in FIG. 3, when the workpiece (4) is fixed, the rod (2) fixed to the workbench is directly passed through the connecting hole (34) of the pawl seat (3), and Do not fix. This allows the pawl (3) to move freely up and down on the rod (2). When gripping the workpiece (4), simply rotating the handle (321) causes the convex ring (32) to press the inner bottom surface of the U-shaped pawl (31), and further the connecting hole ( 34) is tilted so that the inner surface of the coupling hole (34) presses the side surface of the rod (2) to produce a fixing effect, and the work (4) is pressed against the outer bottom surface of the U-shaped pawl (31) to perform work. Fix the object (4).

Further, as shown in FIG. 4, the present invention may combine the tilt adjustment of the flat base (12) by the rotating device (13) to stabilize the cylindrical or spherical workpiece (4). After leaving it for a while, it is possible to further apply pressure from above by the U-shaped pawls (31) to facilitate the work.

FIG. 5 shows one embodiment of the workpiece mounting device of the present invention, in which the claw seat (3) is provided with a screw hole (35) at one time, and one screw hole (35) is provided. Combine the guide screws (5). The guide screw (5) is provided with one handle (51) at the upper end and one claw (52) at the lower end. The handle (51) is rotated to adjust the up and down movement of the guide screw (5), which determines whether to grab or release the workpiece (4).

As shown in FIGS. 6 and 7, there is shown another embodiment of the workpiece attachment device of the present invention. In this embodiment, the rod (2) of the present invention is mounted sideways on the side of the frame (1). Then, the connecting hole (34) of the pawl seat (3) is fitted into the rod (2), and the flat base (12) is adjusted separately to make the workpiece vertical (4) in a vertical state. ) And the flat base (12) and rotate the handle (321) in the same manner as described above to fix the workpiece (4) on the outer bottom surface of the U-shaped pawl (31).

As shown in FIGS. 8 and 9, the method of fixing the rod (2) and the frame (1) of the present invention is to provide a conical protective cap (36) at the lower end of the rod (2) and The lower end of the conical protection cap (36) is extended to provide one screw (361), and the screw (361) is passed through a hole (120) previously formed in the flat base (12), and then a nut or a screw hole is formed. It may also be fixed in combination with the rotary knob (37) it has, which allows the horizontal angle adjustment of the rod (2) to meet the demands of the actual position of the workpiece.
