Detailed Description of the Preferred Embodiments

[0016] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs.

[0017] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they specify the presence of the described features, steps, operations, devices, components, and / or combinations thereof.

[0018] As Figures 1 - 5As shown in the figure, a quick-change positioning fixture for pedal processing includes a bottom plate 1. On both sides of the rear part of the bottom plate 1, there are respectively a first ball plunger 2 and a second ball plunger 3 for leaning against the inner side of the rear edge of the pedal. On both sides of the rear part of the bottom plate, there are respectively a first positioning pin 4 and a second positioning pin 5 which are arranged opposite to the first ball plunger and the second ball plunger and are used for leaning against the outer side of the rear edge of the pedal. On one side part of the bottom plate, there is a third ball plunger 6 for leaning against the inner side surface of the same side edge of the pedal; on the other side part of the bottom plate, there is a third positioning pin 7 for leaning against the inner side surface of the same side edge of the pedal. This positioning fixture has a simple structure, is light in weight and convenient to use. When in use, the workpiece is pre-clamped outside the processing equipment, and then the positioning fixture is installed on the working table of the machining center. The positioning fixture can be transferred between machining centers of different processes together with the pedal, avoiding the frequent disassembly and assembly of the pedal. It can not only quickly and accurately fix the aluminum alloy pedal for mechanical processing, but also facilitate the transfer of the pedal between processing equipment of different processes, realizing quick clamping and continuous multi-process processing, and greatly improving the production efficiency and processing accuracy.

[0019] In this embodiment, there are also several support blocks 8 on the bottom plate for supporting the bottom surface of the pedal. Above the support blocks, there is a pressing block 9. A threaded hole is opened at the upper end of the support block, and a pressing bolt 10 is passed through the pressing block. The lower end of the pressing bolt 10 is threadedly connected to the threaded hole at the upper end of the support block. Before installing the pedal, the pressing block 9 and the pressing bolt 10 are removed. After installing the pedal, the pressing block 9 is placed above the pedal, and the pressing bolt 10 passes through the hollow hole of the pedal and is then connected to the upper end of the support block 8, and the pressing block 9 is tightened to press the pedal by tightening the pressing bolt 10; the whole pressing process is manually operated without power sources such as motors or cylinders, and the positioning fixture does not need to be connected with wires or air pipes, so as to facilitate the transfer of the positioning fixture.
