This invention discloses a car roof rack assembly fixture, comprising: a connecting assembly; a pair of clamping assemblies respectively connected to both ends of the connecting assembly for positioning and clamping the corresponding roof rack; a clamping mechanism connected to the connecting assembly; and an adsorption assembly configured to adsorb onto the glass roof, and applying force to the connecting assembly through the clamping mechanism to press the roof rack clamped by the pair of clamping assemblies firmly against the surface of the glass roof. This car roof rack assembly fixture of the present invention can achieve precise assembly and positioning of the roof rack and glass roof, ensuring the consistency of the final product's appearance and the reliability of the connection, thereby improving production efficiency and product quality. The present invention also discloses a method for assembling a car roof rack and a glass roof.

The present application relates to the technical field of coal mining, and particularly relates to a tool and a method for installing a stand column pressing plate ear plate and a limiting connecting seat, which on one hand provides a tool comprising a first positioning shaft, a horizontal positioning plate, a vertical positioning plate and a second positioning shaft, which has a first circular through hole and a groove in the same relative position relationship as the stand column pressing plate ear plate and the limiting connecting seat are installed on the main reinforcement of the base, and after the tool is positioned with the column nest core positioning hole and the lower bottom surface of the main reinforcement as the reference, the position of the stand column pressing plate ear plate and the limiting connecting seat can be quickly positioned according to the first circular through hole and the groove thereon. On the other hand, a method for installing the stand column pressing plate ear plate and the limiting connecting seat is provided based on the tool, which quickly and accurately positions and installs the stand column pressing plate ear plate and the limiting connecting seat by using the tool, avoids the error of manual measurement and line marking, improves the work efficiency, and is one-time synchronous positioning, which can well ensure the assembly accuracy and ensure the accurate relative position relationship between the two.

The invention discloses a processing method and device of a displacement sensor, a storage medium and electronic equipment, an AMT gear shifting execution mechanism is hoisted to calibration equipment, the calibration equipment comprises a high-precision positioning mechanism, a displacement sliding table, a displacement ruler and a driving mechanism, the driving mechanism is used for driving the displacement sliding table to move along a preset track, and the displacement sliding table moves along the preset track; the method comprises the steps that a displacement sliding table is driven by a driving mechanism to move, a target shaft in an AMT gear shifting execution mechanism is linked to move within the measuring range of the target shaft, and the displacement measurement value of a displacement ruler and the voltage value of a displacement sensor of the AMT gear shifting execution mechanism at each displacement point are obtained; the relative position between the magnetic core on the target shaft and the displacement sensor is changed; based on the displacement measurement value and the voltage value corresponding to the displacement measurement value, a calibration curve is established by adopting a polynomial fitting algorithm, and the calibration curve comprises a mapping relation between the displacement measurement value and the voltage value; and the calibration curve is written into the displacement sensor through controller area network (CAN) communication.
