A Quick Positioning Mechanism for Multi-surface Discontinuous Coaxial Holes

Abstract

The invention relates to the technical field of mechanical processing, and specifically discloses a rapid positioning mechanism for multi-face intermittent coaxial holes, including a mold positioning mechanism and a workpiece positioning mechanism. The left end of the mold positioning mechanism is provided with a side frame, and a The lower support assembly is fixedly connected to the side, the upper support assembly is fixedly connected to the right side of the upper end of the side frame, and a rotating shaft is provided between the lower supporting assembly and the upper supporting assembly, and the outer side of the rotating shaft is fixed with a drill sleeve from top to bottom. frame; in the present invention, drive the rotating shaft and the drill sleeve fixed frame to rotate through the driving motor 1, and then realize the replacement of the die sets required by each process, improve its positioning accuracy, and improve the machining accuracy of each hole position on the entire workpiece; the present invention When in use, when the spacing of the intermittent holes changes, it is only necessary to adjust the spacing of the drill sleeve fixing frame on the rotating shaft to correspond to the spacing of the intermittent holes, thus expanding the applicable range of the entire device.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a rapid positioning mechanism for multi-surface intermittent coaxial holes. Background technique [0002] In the machining process, drilling is a commonly used processing method. In order to ensure the accuracy of drilling, drilling molds are usually used for auxiliary positioning. Coaxial hole parts include tank or roadheader crawler chain accessories. Usually, in order to ensure the flexibility of articulation between each connecting buckle, in the prior art, it is generally necessary to make multiple drills according to the various processes of drilling, expanding and reaming in the drilling process. Although it can achieve a certain guiding effect, it still has the following shortcomings in the process of use: [0003] 1. During the drilling process, during the different processes of drilling, expanding and reaming, it is necessary to replace the mold multiple ...

AI Technical Summary

Problems solved by technology

[0003] 1. During the drilling process, during the different processes of drilling, expanding and reaming, it is necessary to replace the mold multiple times for repositioning, so it is easy to cause cumulative errors and affect the drilling accuracy of the workpiece;

[0004] 2. The same mold can only be used for intermittent holes with the same spacing. When the spacing of the intermittent holes changes, a new mold needs to be made for positioning, so its scope of application is small;

[0005] 3. The replacement of molds in different drilling processes of workpieces is all done by manual positioning, which is easy to cause errors during the operation process, and the operation time is long, which affects the processing efficiency of the entire workpiece
