Description

Automatic flipping fixture

This creation belongs to a type of fixture; in particular, it is a reversible fixture.

Please refer to FIG. 1. FIG. 1 is a workpiece 1 to be held by a fixture in the prior art. In the figure, a workpiece 1 can be seen which is large or small. The workpiece 1 can also be a mold or a processed material. In the prior art, when the working machine holds the workpiece 1, the contour of the workpiece 1 has a slope. During the holding and processing, the workpiece 1 is easily loosened or dumped, which affects the subsequent process and damages the workpiece 1. With this in mind, think about it. If you can turn the workpiece of the workpiece 1, it is good.

Further, in some applications, such as the process of a powder molding machine, the workpiece 1 is liable to have residual powder or deposits, and if the workpiece 1 can be turned over, the residual powder or the attached matter can be removed.

Moreover, the conventional robotic arm, if it is to be improved so that its fixture can properly hold the workpiece 1, it is necessary to write a complicated program, which is awesome and costly, and is not what we want.

The purpose of this case is to provide an automatic flipping fixture to solve the problem that the workpiece is easy to loose or pour, easy to have residual powder or attached matter, and to change the complicated program. The present invention provides an automatic flipping fixture, comprising: a long rail seat comprising a long strip of operation plane; a tumbler switch located at the center of the operation plane; and two long strips of grip arms each of which is supported by a base end of the clamp arm is coupled to the operation plane and is mechanically coupled to the drive unit on the inner side of the operation plane to drive the clamp arm to move along the operation plane to clamp a workpiece, the two base ends Separately located on the two sides of the tumbler, the two clamping arms form a U-shape with the operation plane, and each of the clamping arms has a rotating shaft with respect to a clamping end of the base end, and the rotating shaft is connected with a long strip-shaped clamping arm. The small clamping arm is located inside the Π-shaped shape for inverting the workpiece; and a locator is located at the base end of any one of the clamping arms for triggering the tumbler to trigger the small clamping arm Flip. The jig that is automatically turned over in the present case preferably makes the workpiece not easy to loose or pour, is not easy to have residual powder or attached matter, and does not need to be changed.

Figure 2 is a first preferred embodiment of an automatic flipping fixture of the present invention.

Figure 3 is a second preferred embodiment of an automatically flipped clamp of the present invention.

Please refer to FIG. 2. FIG. 2 is a first preferred embodiment of an automatic flipping fixture of the present invention. The figure shows an automatic flipping fixture 2, comprising: a long rail seat 3, comprising a long operating plane 4 and a driving unit (not shown) disposed in the long rail housing 3; a tumbler switch 5, located in the center of the operating plane 4; two long strips of clamping arms 6, each of which is connected to the operating plane 4 by a base end 7 of the clamping arm 6 and by the base end 7 and the inside of the operating plane 4 The drive unit is mechanically coupled to drive the clamp arm 6 to move along the operation plane 4 to clamp a workpiece 1 shown in FIG. 1. The two base ends 7 are respectively located on opposite sides of the tumbler switch 5, and the two clamp arms 6 and the operation plane 4 Forming a U-shaped shape, each clamping arm 6 has a rotating shaft 9 with respect to a clamping end 8 of the base end 7. The rotating shaft 9 is connected with a long strip-shaped clamping arm 10, and the small clamping arm 10 is located inside the U-shaped shape for turning The workpiece 1; and a positioner 11 are located at the base end 7 of any of the two arms 6 for triggering the tumbler 5 to trigger the flip of the small arm 10.

As stated above, the drive unit is one of a gear set, a pulley set, a chain or a link or any combination thereof.

As described above, the jig 2 may further include two restriction cassettes 12 located on the outermost sides of the operation plane 4 to limit the maximum degree of development of the two clamp arms 6.

As mentioned above, the clamp 2 can be located on a powder molding machine.

Referring to FIG. 3, FIG. 3 is a second preferred embodiment of an automatically flipped clamp of the present invention. As described above, the rotating shaft 9 of the clamp 2 can be located at the center of the small clamp arm 10.

This case has been modified by people who are familiar with the art, but it is not intended to be protected by the scope of the patent application.
