Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.
[0021] 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 features, steps, operations, devices, components, and / or combinations thereof.
[0022] As Figures 1 to 8 shown, a fixture system for pedal processing includes a secondary positioning jig B and a main fixture A for fixing the secondary positioning jig. The secondary positioning jig B includes a base plate 1. On both sides of the rear part of the base plate 1, a first ball plunger 2 and a second ball plunger 3 are respectively provided for leaning against the inner side of the rear edge of the pedal. On both sides of the rear part of the base plate, a first positioning pin 4 and a second positioning pin 5 are respectively provided opposite to the first ball plunger and the second ball plunger and for leaning against the outer side of the rear edge of the pedal. On one side part of the base plate, a third ball plunger 6 is provided for leaning against the inner side surface of the same side edge of the pedal; on the other side part of the base plate, a third positioning pin 7 is provided for leaning against the inner side surface of the same side edge of the pedal. This secondary positioning jig has a simple structure, is light in weight, and is convenient to use. When in use, the workpiece is pre-clamped outside the processing equipment, the main fixture A is installed on the working table of the machining center, and then the secondary positioning jig is installed on the main fixture A of each machining center. The secondary positioning jig 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. Through the combined use of the main and secondary jigs, rapid clamping and continuous multi-process machining are realized, greatly improving the production efficiency and machining accuracy.
[0023] In this embodiment, the main fixture A includes a seat plate 14. On the upper side of the seat plate 14, a number of anti-fooling pins 15 are provided for leaning against the edge part of the base plate of the secondary positioning jig. Above the seat plate, a number of pressing plates 16 are provided for pressing and fixing the base plate. A number of anti-fooling pins 15 enclose a working station for placing the secondary positioning jig B. The main fixtures A in different machining centers can be provided with anti-fooling pins 15 at different positions, thereby changing the installation angle of the secondary positioning jig B to adjust the installation angle of the pedal to correspond to different processing procedures.
[0024] In this embodiment, a plurality of hollow slots 11 are formed in the bottom plate 1 for the pressing plate 16 to pass through. A clamping cylinder (not shown in the figure) for driving the pressing plate to lift is provided at the bottom of the seat plate 14. The telescopic rod of the clamping cylinder passes upward through the hollow slots of the seat plate and the bottom plate and is hinged to the middle of the pressing plate. When installing the secondary positioning jig B, the pressing plate 16 passes through the hollow slot 11 of the secondary positioning jig B, and then the pressing plate 16 is rotated by 90° and clamped above the hollow slot 11 to press the bottom plate.
[0025] In this embodiment, a plurality of support blocks 8 for supporting the bottom surface of the foot pedal are further provided on the bottom plate. A pressing block 9 is provided above the support block. A threaded hole is formed at the upper end of the support block. A pressing bolt 10 is passed through the pressing block. The lower end of the pressing bolt is threadedly connected to the threaded hole at the upper end of the support block. Before installing the foot pedal, the pressing block 9 and the pressing bolt 10 are removed. After installing the foot pedal, the pressing block 9 is placed above the foot pedal. The pressing bolt 10 passes through the hollow hole of the foot pedal and is connected to the upper end of the support block 8, and the pressing block 9 is pressed against the foot pedal by tightening the pressing bolt 10; the entire pressing process is manually operated without power sources such as motors or cylinders, and the positioning jig does not need to be connected to wires or air pipes, so as to facilitate the transfer of the positioning jig.
[0026] In this embodiment, two jig positioning holes 12 are arranged at diagonal positions on the bottom plate, and positioning convex shafts 17 matching the jig positioning holes 13 are provided on the seat plate 14. The arrangement of the jig positioning holes 12 facilitates the positioning of the jig on the machining center.
[0027] In the specific implementation process, three sets of main fixture jigs and three sets of secondary positioning jigs B can be designed. During use, the three main fixture jigs are respectively installed on the workbenches of three machining centers, and each main fixture jig corresponds to one process (OP1, OP2, OP3 respectively). The secondary positioning jig B pre-clamps the workpiece outside the equipment and then is quickly installed on the main fixture jig for positioning and clamping. After the OP1 processing is completed, the secondary positioning jig B can be quickly transferred to OP2 and finally to OP3 to complete the processing. During this process, due to the different operation times of OP1, OP2 and OP3, especially after OP3 is completed, the processed foot pedal can be removed and the unprocessed foot pedal can be reinstalled while OP1 and OP2 are still running, so as to achieve continuous production, reduce the equipment downtime, avoid the equipment from idling due to clamping, and improve the equipment utilization rate; significantly reduce the clamping time, improve the processing efficiency; simplify the operation process, reduce the operation difficulty, and improve the processing accuracy.
[0028] Moreover, since the footrest is divided into left and right sides, the secondary positioning fixture is also divided into left and right sides, and the left and right sides are symmetric structures. Anti-false pins and positioning cam shafts for installing the left and right secondary positioning fixtures are respectively provided on the main tooling fixture, and two workstations on the left and right are reserved to meet the processing requirements of the left and right footrests. When machining the left footrest, install the left secondary positioning fixture on the main tooling fixture, and achieve quick positioning and clamping through the anti-false pin and the positioning cam shaft. Similarly, when machining the right footrest, just install the right secondary positioning fixture on the main tooling fixture. The structure of the main tooling fixture remains unchanged, and quick switching and continuous processing of the left and right footrests can be realized by simply replacing the secondary positioning fixture. It reduces the time and cost expenditures caused by replacing the main tooling fixture, improves production efficiency; simplifies the operation process, and the operator only needs to replace the secondary positioning fixture to start machining, reducing the operation difficulty; reduces the equipment downtime, avoids the equipment from idling due to clamping, improves the equipment utilization rate, and reduces the production cost.

Moreover, the listed numerical values should not constitute a limitation on the protection scope of the creation of the present utility model.
