Processing equipment for exhaust pinholes in inner cavity of refrigerator

The invention discloses processing equipment for exhaust pinholes in an inner cavity of a refrigerator. The processing equipment comprises spare parts, such as a base, straight guide rails, two sets of U-shaped seats, cylinders, needle insertion units, rubber pressing plates and an adjusting screw, wherein the U-shaped seats are mounted on the base through the straight guide rails; the cylinders and the rubber pressing plates are mounted on one sides of the U-shaped seats, and multiple sets of the needle insertion units are mounted on the other sides of the U-shaped seats; one set of the U-shaped seats is connected with the adjusting screw, and the positions of the U-shaped seats on the straight guides can be adjusted through the screw; the other set of the U-shaped seats is connected with the cylinders, and the U-shaped seats can be driven by the cylinders so as to move along the straight guide rails in a reciprocating manner; each needle insertion unit consists of an inserting needle, a body, a clamping jaw, a sliding bush, springs, a locking nut, a pulling nut and the like; and the rubber pressing plates are pushed by the cylinders to complete the hole inserting processing on the side wall of the inner cavity of the refrigerator with the needle insertion units. The processing equipment disclosed by the invention has the benefits that exhaust holes are processed in the side wall of the inner cavity of the refrigerator through the processing equipment, the automation of hole inserting processing and the precision of hole inserting positions are realized, the production efficiency is greatly improved, the labor intensity is reduced, and the processing quality of products is ensured.
