Description
Technical Field
[0001] The utility model relates to the technical field of steering systems, in particular to a left and right shear block error-proof tooling for a U-shaped bracket. Background Art
[0002] For the U-shaped bracket of the electric column, two shear blocks are usually used to locate and meet the requirements of vehicle collapse. Due to the different interfaces of the whole vehicle, the aperture sizes of the shear blocks are also different. The normal locating pins are also designed according to the aperture. Generally speaking, a shear block with a small aperture cannot be placed on the corresponding large-aperture locating pin. However, if large-aperture shear blocks are installed on both sides, error prevention cannot be achieved during the production process. The conventional solution is manual visual inspection, but this solution cannot completely avoid misinstallation. In order to meet customer quality requirements, a solution that can prevent misinstallation has been developed. This solution adds a compression lock spring, a slider and a proximity switch sensor at the locating pin, modifies the PLC program, and uses the difference in the aperture of the left and right shear blocks to achieve the two states of 0 and 1 of the proximity switch sensor, thereby achieving the effect of error prevention.

[0020] The utility model is further described below with reference to the accompanying drawings.
[0021] like Figures 1 to 5 As shown, the middle part of the bottom plate 1 is connected to the middle base 5, and the left and right sides of the middle base 5 are respectively connected to the left base 2 and the right base 6; the top of the left base 2 is connected to the left positioning pin 4, and a left fixed pressure clamp 3 is provided on one side of the left positioning pin 4; the top of the right base 6 is connected to the right positioning pin 8, and a slider 10 is provided on one side of the right positioning pin 8, and a proximity switch 7 is provided on the front side of the slider 10; a right fixed pressure clamp 9 is provided on the right side of the right positioning pin 8.
[0022] The left fixed pressing clamp 3 is located at the upper left side of the left positioning pin 4 .
[0023] The left base 2 is a Z-shaped module structure.
[0024] The right fixed pressing clamp 9 is located at the upper right side of the right positioning pin 8 .
[0025] The right base 6 is a Z-shaped module structure.
[0026] The bottom of the slider 10 is connected to the top of the right base 6 via a compression spring 11 .
[0027] The proximity switch 7 is connected to the front portion of the right base 6 via a sensor bracket 12 .
[0028] The head of the proximity switch 7 is located at the front side of the slider 10 .
[0029] The specific operation of the utility model is as follows:
[0030] U-shaped bracket of the steering column (such as Figure 6 As shown) is placed on the utility model tooling (as shown Figure 7 As shown), positioning is performed by the left positioning pin 4 and the right positioning pin 8 on the left and right sides.
[0031] The left side fixed pressing clamp 3 and the right side fixed pressing clamp 9 are used for pressing and fixing.
[0032] When the correct shear block 13 is installed in the tooling of the utility model, the shear block 13 will press the slider 10 downward (such as Figure 3 As shown), until the proximity switch 7 is touched, the sensor lights up, the PLC signal is transmitted to the equipment, and production can run normally.
[0033] When the incorrect shear block 13 is installed into the tooling of the utility model, the shear block 13 does not contact the slider 10, and the slider 10 cannot be pressed down. The slider 10 cannot touch the proximity switch 7, the proximity switch 7 cannot light up, and the production cannot run normally.
[0034] The utility model utilizes the difference in apertures of the left and right shear blocks to realize two states of 0 and 1 of the proximity switch sensor, thereby achieving an error-proofing effect. When the shear block is a waist-shaped hole (small aperture), the shear block contacts the slider to press the slider down. The slider touches the proximity switch sensor under the action of the compression spring, and the proximity switch sensor lights up. When the shear block is a circular hole (large aperture), the shear block does not contact the slider, the slider cannot be pressed down, the slider cannot touch the proximity switch sensor, and the proximity switch cannot light up.
