Technical Field

[0001] This utility model relates to the field of automotive instrument crossbeam processing technology, specifically a multi-station automotive instrument crossbeam welding and positioning device. Background Technology

[0002] The dashboard of a car is equipped with various instruments and an ignition switch. It is made of metal or plastic casting mold and allows the driver to understand and adjust the car's operating status and various data. In order to support the dashboard, a crossbeam is usually installed inside the panel for fixation.

[0003] The horizontal structure consists of multiple sets of rods with varying thicknesses and angles. To facilitate rapid assembly and fixation, welding positioning devices are often used to assist in the assembly process. The surface of the crossbeam assembly can be melted by laser and then assembled by extrusion. However, the welding stations for this type of mechanism are limited, requiring the crossbeam body to be constantly disassembled and its orientation changed to accommodate different components. This process is time-consuming and affects the stability of the assembly.

[0004] Now, a novel multi-station automotive instrument crossbeam welding positioning device is proposed to solve the above problems. Utility Model Content

The base plate has an internal cavity, and a gear is movably connected between the upper and lower parts of the center of the cavity. A rear gear is movably connected to the rear of the gear, and a left frame is fixed to the left side of the top of the rear gear. A front gear is movably connected to the front of the gear, and a right frame is fixed to the right side of the top of the front gear. Slots are respectively provided on the left rear and right front of the top of the base plate. Laser heads are respectively fixed to the tops of the left and right frames. Laser welding machines are respectively installed on both sides of the center of the upper part of the base plate, and a conduit is fixed between the laser welding machines and the laser heads. Limiting grooves are respectively fixed to the rear and front of the cavity. A motor is fixed to the center of the lower part of the outer side of the base plate. A middle beam is horizontally arranged at the center of the upper part of the base plate, and a left crossbeam is arranged to the left of the middle beam, and a right crossbeam is arranged to the right of the middle beam.

[0007] As a further technical solution of this utility model, the top of the output end of the motor is fixedly connected to the gear, and the rear of the rear gear and the front of the front gear are respectively embedded in the limiting groove.

[0008] As a further technical solution of this utility model, the right frame and the left frame are each embedded in the slot, and the rear toothed rod moves in the opposite direction to the front toothed rod.

[0009] As a further technical solution of this utility model, a bracket is fixed at the center of the outer top of the base plate, and a second cylinder is installed at the top of the outer side of the bracket. An upper sleeve is fixed at the bottom of the piston rod of the second cylinder. A threaded groove is provided at the center of the lower part of the bracket, and a screw is threadedly connected in the threaded groove. A nut is screwed onto the outside of the screw. A lower sleeve is movably connected to the top of the screw. The upper sleeve and the lower sleeve are symmetrically engaged at the upper and lower parts of the surface of the intermediate beam.

[0010] As a further technical solution of this utility model, the inner cavities of the upper and lower ferrules have the same curvature, and the upper and lower ferrules have the same length.

[0011] As a further technical solution of this utility model, the screw rotates longitudinally in the threaded groove, and the inner wall of the nut matches the outer wall of the screw.

[0013] As a further technical solution of this utility model, the sleeve slides vertically along the surface of the column, and the clamping plate rises and falls vertically with the piston rod of cylinder one.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the multi-station automotive instrument crossbeam welding positioning device not only realizes dual-station welding and prevents the main crossbeam from shaking, but also realizes rapid assembly of side beams.

[0016] (2) A bracket is fixed at the center of the top of the outer side of the base plate, and the middle beam is embedded in the bracket. The bottom screw is rotated in advance to make the lower sleeve rise and fall along the thread groove. Then the nut is used to lock and fix it. The lower sleeve is moved to make it on the same vertical plane as the upper sleeve. Then the cylinder is started and the piston rod is used to sink the upper sleeve to clamp and fix the middle beam. The clamping distance can be automatically adjusted.

[0017] (3) By fixing a frame at the top of the sleeve, the left and right crossbeams on both sides are respectively embedded in the frame. The sleeve is pre-lifted along the column and locked with bolts. Then, the left and right crossbeams are fixed separately by the vertical lifting clamp plate of the cylinder at the top. It can be assembled and laser heat-fused with the middle beam at the center. Even if the specifications of the left and right accessories are not the same, the clamping mechanism can be changed spontaneously. Attached Figure Description
