Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

A right angle positioner for wire-electrode cutting as shown in the figure, including base 1, place the spacing module of right angle on the base 1. The right-angle limiting module comprises a bottom plate 2, the bottom plate 2 is in contact with the base 1, and an L-shaped limiting block 3 is arranged on the bottom plate 2. During the use, the work piece is placed on bottom plate 2, and the right angle of work piece is hugged closely the right angle of 3 inboards of L type stopper.

Still be equipped with fastener on the base 1, fastener includes first screw thread post 5, and screw hole cooperation and the fixing on base 1 on first screw thread post 5 and the bottom plate 2. The locking device also comprises a first pressing plate 6 and a locking bolt 4, wherein the first pressing plate 6 is sleeved on the first threaded column 5. When the locking device is used, the first pressing plate 6 is pressed on the L-shaped limiting block 3, and the locking bolt 4 rotates downwards, so that the right-angle positioning device is pressed on the base by the pressing plate. The fastening devices are provided with two or more than two, and are respectively pressed on the longitudinal edge and the transverse edge of the L-shaped limiting block 3.

The L-shaped limiting block 3 is also provided with a workpiece fastening device which comprises a second threaded column fixed on the L-shaped limiting block 3, a second pressing plate sleeved on the second threaded column and a second fastening bolt matched with the second threaded column, wherein the second fastening bolt is arranged above the second pressing plate. During the use, the second clamp plate presses on the work piece, and the bolt is twisted downwards, makes the clamp plate compress tightly the work piece.

Furthermore, in order to ensure that the stress of the fastening device for fixing the L-shaped limiting block 3 is more balanced during working, one side of the first pressing plate is pressed on the L-shaped limiting block, the other side of the first pressing plate is provided with a cushion block on the base, the first pressing plate is pressed on the cushion block, and the height of the cushion block is not higher than that of the L-shaped limiting block.

It will be appreciated by those of ordinary skill in the art that the embodiments described herein are intended to assist the reader in understanding the principles of the invention, and it is to be understood that the scope of the invention is not limited to such specific statements and embodiments. Those skilled in the art can make various other specific modifications and combinations based on the teachings of the present invention without departing from the spirit of the invention, and such modifications and combinations are still within the scope of the invention.
