[0015] Figure 2 for Figure 1 The main view. Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0017] like Figures 1-2As shown, a multi-station automatic drilling fixture for instrument panel pipe beams includes a fixture trolley 1, a trolley platform 2 at the upper end of the fixture trolley, and a traveling wheel 3 at the lower end of the fixture trolley. An electrical control cabinet 4 is installed on the fixture trolley, and a PLC control system is installed inside the electrical control cabinet. The PLC control system is electrically connected to a switch box 5, which is fixedly installed on the trolley platform.

[0018] The trolley platform is equipped with a clamp body for clamping the instrument panel beam. Several mounting seats are fixedly installed on the trolley platform. A dual-servo drilling and tapping power head 6 is fixedly installed on the mounting seats. The dual-servo drilling and tapping power head is electrically connected to the PLC control system. A drill bit is fixedly installed on the execution end of the dual-servo drilling and tapping power head.

[0019] In this way, when drilling the instrument panel tube beam 7, the instrument panel tube beam is clamped and fixed by the fixture body and positioned at the same time. Then, the dual servo drilling power heads move synchronously to drill the instrument panel tube beam, which improves the drilling efficiency.

[0020] Specifically, the dual-servo drilling and tapping power head is an existing structure and will not be described in detail here.

[0021] In practice, the fixture body includes a left contour positioning block 8 and a right contour positioning block 9 fixedly mounted on the trolley platform. The left contour positioning block and the right contour positioning block have contour surfaces that fit against the instrument panel tube beam.

[0022] Positioning columns are fixedly installed at both ends of the trolley platform. A positioning plate 10 is fixedly installed on one of the positioning columns, and a positioning cylinder 11 is fixedly installed on the other positioning column. The cylinder rod of the positioning cylinder is fixedly installed with a positioning block 12 through a mounting bracket.

[0023] The trolley platform is also equipped with two side pneumatic clamping mechanisms and one central pneumatic clamping mechanism, with the central pneumatic clamping mechanism located between the two side pneumatic clamping mechanisms.

[0024] In this way, the instrument panel tube beam is supported by the left and right contour positioning blocks. One end of the instrument panel tube beam abuts against the positioning plate. The positioning cylinder drives the positioning block to move, and the positioning block is used to press and position the instrument panel tube beam. Then, the instrument panel tube beam is further fixed by two side pneumatic pressing mechanisms and one middle pneumatic pressing mechanism, which improves the stability of the clamping and thus improves the drilling accuracy.

[0025] In practice, the side pneumatic clamping mechanism includes a side clamping cylinder 13, which is fixedly mounted on a side cylinder seat. The side cylinder seat is fixedly mounted on a trolley platform. The cylinder rod of the side clamping cylinder passes through the side cylinder seat and is fixedly mounted with a side clamping block 14. Abutment blocks 15 are fixedly mounted on both the side pneumatic clamping mechanism and the middle pneumatic clamping mechanism on the trolley platform.

[0026] In this way, the abutment block can support the instrument panel tube beam, and the side clamping cylinder can drive the side clamping block to clamp and fix the instrument panel tube beam.

[0027] In practice, the pneumatic clamping mechanism includes a cylinder frame fixedly installed on the trolley platform, a central clamping cylinder 16 fixedly installed on the cylinder frame, and a pressure plate 17 fixedly installed on the cylinder rod of the central clamping cylinder.

[0028] In this way, the abutment block can support the instrument panel beam, and the intermediate pressure cylinder can drive the pressure plate to press and fix the instrument panel beam.

[0029] In practice, the trolley platform is fixedly equipped with auxiliary supports of the same number as the dual-servo drilling and tapping heads. An auxiliary plate 18 is fixedly installed on each auxiliary support, and the auxiliary plate has an auxiliary hole coaxial with the drill bit, facing the drill bit. This facilitates auxiliary positioning of the drill hole.

[0030] This fixture uses a PLC system to control multiple dual-servo drilling and tapping heads to simultaneously perform multi-station drilling. Compared with previous processing methods, it improves the automation level of the equipment, increases production efficiency several times, and enhances product quality and customer satisfaction, creating more benefits for enterprises.

[0031] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
