Problems solved by technology
The fuel pump works when starting and the engine is running, which plays a key role in the overall quality of the car. There are two important support rods in the fuel pump bracket assembly. One end of the support rod is installed on the plastic part with interference fit, and the other end is installed Spring, because the structure and size of both ends of the support rod are very close, it is very easy for the operator to confuse when assembling. The waste caused by the wrong support rod is relatively large

Embodiment
[0022] The operator puts the support rod into the support rod press-fit slot, and the support rod falls into the support rod press-fit slot by its own weight. The proximity switch receives the signal, and the needle-shaped cylinder works to drive the error-proof profiling block to rise. If the position of the support rod port is Correct, the support rod will fall into the profiling groove, and the inspection is qualified at this time; if the position of the support rod is incorrect, the support rod cannot fall into the profiling groove, and the support rod will be lifted from its original position on the error-proof profiling block , at this time, the proximity switch will give an alarm if there is no signal. At this time, the inspection is not qualified. The operator restarts the inspection after troubleshooting.

The invention discloses an error-proofing device before press fitting of a supporting rod. The error-proofing device comprises an executive element, an error-proofing profiling block, an executive element connecting block, a T-shaped guide rail and a supporting rod press-fitting slot, wherein a guide rail screw hole is formed in the T-shaped guide rail; the executive element is fixedly arranged in the guide rail screw hole; a profiling slot, a small T-shaped slot and a large T-shaped slot are formed in the error-proofing profiling block; the executive element is mounted in the small T-shaped slot through the executive element connecting block; the error-proofing profiling block is mounted on the T-shaped guide rail through the large T-shaped slot; the error-proofing copying block can be driven by the executive element to slide along the T-shaped guide rail; the side surface of the supporting rod press-fitting slot is provided with a proximity switch; and a supporting rod is arranged in the supporting rod press-fitting slot. According to the error-proofing device, the shape of the profiling slot is completely consist with that of one end of the supporting rod, and the dimension of the profiling part of the profiling slot is greater than the corresponding dimension of shape of one end of the supporting rod. The error-proofing device is simple in manufacturing process, and is convenient to use, thereby avoiding press-fitting errors of the supporting rod, improving the qualified rate of assembly parts, and reducing waste caused by mistake press-fitting.
Description
technical field [0001] The invention relates to the technical field of assembling fuel pump brackets for automobile accessories, in particular to an error prevention device before press-fitting a support rod. Background technique [0002] The fuel pump is an accessory of the car. It is installed in the fuel pump bracket and forms the fuel pump bracket assembly with the fuel pump bracket. Continuous supply of fuel. The fuel pump works when starting and the engine is running, which plays a key role in the overall quality of the car. There are two important support rods in the fuel pump bracket assembly. One end of the support rod is installed on the plastic part with interference fit, and the other end is installed Spring, because the structure and size of both ends of the support rod are very close, it is very easy for the operator to confuse when assembling. The waste caused by the wrong support rod is relatively large. Contents of the invention [0003] The object of t...
