DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a multifunctional fixture for machining includes a fixture base 1, a fixture bracket 2 is fixedly mounted on the upper end of the fixture base 1, and a pneumatic fixture assembly 5 is fixedly mounted on the fixture bracket 2.

[0020] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the outer side of the clamp base 1 is provided with a baffle collection structure 3, which consists of an annular baffle plate 6, an annular collection groove 7 and a fixed snap ring 9. The annular collection groove 7 is fixedly installed on the lower inner wall of the annular baffle plate 6. There are two fixed snap rings 9 and they are symmetrically fixed on the outer wall of the annular baffle plate 6. The baffle collection structure 3 is provided with a heightened enclosure 4, which consists of an arc-shaped baffle plate 10, an arc-shaped bar 12, an annular spring 14 and a pull block 15. There are two arc-shaped baffle plates 10 and they are symmetrically arranged. There are four arc-shaped bars 12 and they are symmetrically fixed on the outer walls of the two arc-shaped baffle plates 10 in pairs. There are two annular springs 14 and they are installed in the four arc-shaped bars 12. There are two pull blocks 15 and they are respectively fixed on the outer walls of the two arc-shaped baffle plates 10. Two connecting brackets 8 are symmetrically fixed on the inner wall of the annular collection groove 7 on the baffle collection structure 3, and the connecting bracket 8 is simultaneously connected to the clamp The tool bracket 2 is fixedly connected, and two arc grooves 11 are symmetrically provided on the inner wall of the arc-shaped enclosure plate 10 on the raised enclosure 4. The inner wall of the arc-shaped enclosure plate 10 contacts the outer wall of the annular enclosure plate 6 on the enclosure collecting structure 3. An arc groove 13 is provided on the outer wall of the arc bar 12 on the raised enclosure 4. The pull block 15 is located between the two arc bars 12, and the annular spring 14 is installed in the arc groove 13 provided on the outer wall of the arc bar 12. The arc-shaped enclosure plate 10 is clamped on the fixed clamping ring 9 through the arc groove 11 under the elastic force of the annular spring 14. By setting the enclosure collecting structure 3 and the raised enclosure 4, the workpiece fixed by the clamp can be enclosed, so that when the drill bit drills the workpiece, the flying debris will be blocked by the enclosure collecting structure 3 and the raised enclosure 4, thereby reducing the probability of debris hitting the surrounding workers, and ultimately reducing the probability of safety accidents occurring during the drilling process of the workpiece.

[0021] It should be noted that the present invention is a multifunctional fixture for machining. When in use, the workpiece to be machined can be fixed by the pneumatic clamp assembly 5, thereby fixing the workpiece to be machined to the upper end of the clamp base 1, and then the heightened enclosure 4 can be moved upward for adjustment. The method is to first pull the arc-shaped enclosure plate 10 through the pull block 15, so that the two arc-shaped enclosure plates 10 are separated from each other. At this time, the annular spring 14 will be stretched and deformed. When the fixed clamp ring 9 on the enclosure collection structure 3 is passively disengaged from the arc-shaped groove 11, the heightened enclosure 4 can be moved upward, and the arc-shaped enclosure 10 on the lower side can be adjusted. After the slot 11 is flush with the upper fixed retaining ring 9, you can stop pulling the pull block 15. At this time, under the elastic force of the annular spring 14, the arc-shaped enclosure plate 10 will move toward the enclosure collection structure 3, and finally the arc-shaped enclosure plate 10 will be stuck on the fixed retaining ring 9 through the arc-shaped slot 11. At this time, the upward adjustment of the raised enclosure 4 is completed, and then mechanical equipment can be used to drill the workpiece. The debris generated during the drilling process will splash around. At this time, the annular enclosure plate 6 and the arc-shaped enclosure plate 10 will block the debris, and the blocked part of the debris will fall into the annular collection groove 7 under the influence of gravity.
