Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a high-precision positioning jig for processing channel beam box bodies. Background Technology

[0002] Due to its structural characteristics, the trough-beam box girder has numerous stiffening ribs and box diaphragms, making its fabrication process complex and assembly difficult. Existing jig structures only address the erection of individual modules during the fabrication of the trough-beam box girder, resulting in low automation, poor work efficiency, and unsatisfactory precision control, which seriously affect project quality and schedule.

[0003] Therefore, there is an urgent need to provide a highly automated jig for processing channel beam box bodies that can achieve high-precision positioning of components, so as to meet engineering quality requirements while shortening the processing cycle. Utility Model Content

The jig base is equipped with a jig panel, and the electric limit blocks and electric tower are slidably installed on the jig panel. The electric tower is equipped with a lifting slide rail and a robotic arm. The box body bottom plate is installed above the jig base, and several electric limit blocks abut against the end face of the box body bottom plate respectively.

[0006] The robotic arm moves up and down along the lifting slide rail, and a rotating gripper is installed at the end of the robotic arm facing the box.

[0007] Preferably, the base of the tire frame includes a tire frame panel, a tire frame base crossbar, a tire frame base vertical bar, and an adjustable screw, with digital display infrared rangefinders installed on the tire frame base vertical bars around the perimeter.

[0009] Preferably, the bottom plate of the box has several stiffening ribs along the length direction, and the bottom of the limit caliper is provided with a limit groove according to the spacing of the stiffening ribs; when the limit caliper is installed on the bottom plate of the box, the rotating gripper holds the end of the limit caliper.

[0010] Preferably, the electric tower crane controls the elevation position of the robotic arm via a lifting slide rail, and the robotic arm can be adjusted in length.

[0011] The beneficial effects of this utility model are:

[0012] 1) The jig assembly involved in this utility model adopts electric limit blocks, limit calipers and electric tower. The electric limit blocks accurately position the bottom plate of the box body, the mechanical arm and limit calipers accurately position the box body partition, and the mechanical arm individually and accurately controls the installation position of the box body web plate and the box body flange plate, thus realizing the high-precision processing and manufacturing of the channel beam box body.

[0013] 2) The base of the jig involved in this utility model can adjust the elevation through the adjustable screw at the bottom, and can determine the level of a single jig panel according to the set digital display infrared rangefinder, and can further calibrate the elevation of each independent jig base in the entire jig system.
