Description

Technical Field

[0001] The utility model relates to the technical field of steering wheel processing, and more specifically, to a screw error-proof installation tool. Background Art

[0002] A wheel-shaped device that controls the direction of travel in cars, ships, airplanes, etc. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. The steering wheel switch must be fixed with screws.

[0003] For example, the authorization announcement number CN210588045U discloses an automatic screw-driving tool, which can drive the screw to rotate by rotating the rocker, and the screw can drive the rectangular block to move inward when the screw rotates through the threaded connection between the screw and the rectangular block. The rectangular block drives the hollow plate and the insertion rod to move inward through the connecting block, so that some of the insertion rods first contact the plastic part for clamping. Through the continued movement of the hollow plate, the insertion rods in contact with the plastic part can gradually shrink toward the inner cavity of the hollow plate, and the hollow plate drives the remaining insertion rods to move inward to contact the plastic part and clamp it, so that it can be clamped and fixed according to the different specifications and shapes of the plastic parts, avoiding affecting the screw-driving tooling work of the circuit board and plastic parts, improving the working efficiency of the screw-driving tooling of the circuit board and plastic parts, and facilitating wide promotion.

[0004] However, for the steering wheel, since the screws on the steering wheel are arranged around the steering wheel, the position requirements for the screws are higher. During use, the above solution often results in missed, wrong, or repeated screws, affecting the steering wheel's yield and production efficiency. Utility Model Content

[0007] A screw error-proof installation tool comprises a chassis, a workbench is provided on the chassis, a clamping structure, a bracket and an adjustment mechanism connected to the bracket are provided on the workbench,

[0008] The clamping structure includes a placement plate, four support frames, a first placement seat and a second placement seat. The placement plate is connected to the workbench. The support frames are respectively placed at the four corners of the placement plate. A placement station for placing the steering wheel is formed between the four support frames. The first placement seat and the second placement seat are placed between the four support frames. The first placement seat and the second placement seat are arranged flush with each other. Points for screwing are provided on the first placement seat and the second placement seat.

[0009] The adjustment mechanism includes a support rod, a two-way cylinder, a guide rod and an adjustment seat. The support rod is connected to the workbench, the two-way cylinder is slidably connected to the support rod, and a spring lifting mechanism is connected to the two-way cylinder.

[0010] An electric screw gun is provided on one side of the two-way cylinder, and the other side of the two-way cylinder is connected to the guide rod. The electric screw gun is placed above the placement station, and one end of the guide rod is connected to the adjustment seat.

[0011] The utility model is further configured as follows: the adjustment seat includes an upper seat body, a lower seat body and a connecting rod for connecting the upper seat body and the lower seat body; a special-shaped groove is provided on the upper seat body; an adjustment hole is provided at a corresponding point in the special-shaped groove; the adjustment hole passes through the upper seat body; a sensor 1 is provided on the connecting rod corresponding to the adjustment hole; and the sensor 1 is electrically connected to the electric screw gun.

[0012] The utility model is further configured as follows: a second sensor is provided on the side of the first placement seat, a pressure block is provided on the second placement seat, a pushing cylinder is provided corresponding to the pressure block, the output end of the pushing cylinder contacts the pressure block, and a fixed seat connected to the placement plate is provided under the pushing cylinder.
