[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0021] like Figure 1-3As shown, an adjustable angle V-shaped iron includes a V-shaped body 1, a base 2, a driven wheel 3, a driving wheel 4, a transmission shaft 5 and a handwheel 6. The V-shaped body 1 is rotatably mounted on the base 2, and a reference scale 7 is provided on the outer side of the lower end of the V-shaped body 1. The outer circumferential side of the base 2 is provided with an angle scale 8 of 0 to 360 degrees. The bottom of the base 2 is connected with a positioning protrusion 9 for cooperating with the positioning groove of the milling machine platform. The top of the base 2 is provided with a first groove 10 and a second groove 11. The first groove 10 is provided in the middle of the top of the base 2, and the first groove 10 and the second groove 11 are connected. The driven wheel 3 is provided in the first groove 10, and the driven wheel 3 is fixedly connected to the bottom of the V-shaped body 1 by a first fastener 12. The driving wheel 4 is provided in the second groove 11. The transmission shaft 5 is rotatably mounted on the side end of the base 2. One end of the transmission shaft 5 extending into the second groove 11 is fixedly connected to the driving wheel 4, and the other end extends out of the base 2 and is fixedly connected to the handwheel 6 through a second fastener 13.

[0022] The base 2 is a cylindrical structure. The lower section of the V-shaped body 1 is cylindrical and fits in with the upper surface of the base 2. The reference mark 7 provided on the V-shaped body 1 is used to determine the current angle of the V-shaped body 1. The upper section of the V-shaped body 1 is a V-shaped support structure with a certain thickness to support the workpiece.

[0023] The positioning protrusion 9 is a rectangular protrusion, a T-shaped protrusion or a dovetail-shaped protrusion.

[0024] The minimum scale value of the angle scale 8 is 1°.

[0025] The first fastener 12 and the second fastener 13 are both screws.

[0026] The driving wheel 4 and the driven wheel 3 are both bevel gears. In this embodiment, a bevel gear pair is used for transmission, but it is not limited to a bevel gear pair, and can also be a worm gear pair.

[0027] To adjust the angle, assemble all parts according to the assembly drawing. The motion of the rotating handwheel 6 is transmitted to the V-shaped body 1 through the meshing action of the driving wheel 4 and the driven wheel 3, causing the V-shaped body 1 to rotate. The current angle is determined by observing the position of the angle scale 8 corresponding to the reference scale line 7 on the V-shaped body 1. This utility model can quickly and conveniently adjust the angle of the workpiece and achieve rapid positioning.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, improvements, component splits, or combinations that fall within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
