Problems solved by technology

At present, the method used to remove the screws in small deep blind holes is to use tools such as fixtures, height gauges, vernier calipers, marking needles, positioning tools and other tools to position and then drill holes. Using this method cannot ensure the stable installation of parts, and it is harmful to the operator's skills. The level requirements are high, the probability of error is high, and when repairing small deep holes in different positions, tooling needs to be remade, which affects maintenance efficiency

Abstract

The invention discloses a composite small deep hole and blind hole broken nail taking-out device. The composite small deep hole and blind hole broken nail taking-out device comprises two floating clamping plates capable of tightly wrapping a plane electric appliance part. The two end surfaces of the two floating clamping plates are each fixedly provided with an elastic connecting plate through a bolt. The outer walls of the two floating clamping plates are each provided with a clamping groove. A transverse sliding block in sliding fit with the clamping grooves is installed on the floating clamping plates. A spring clamping piece is installed on a sliding surface of the transverse sliding block. The upper surface of the transverse sliding block is provided with a long strip-shaped hole. A positioning sleeve is installed in the long strip-shaped hole from outside to inside through a nut. A guide sleeve is installed in the positioning sleeve from the outer end of the nut to the inside. The transverse sliding block is provided with a fastening screw towards a floating sliding block. The composite small deep hole and blind hole broken nail taking-out device has the advantages of being simple in structure, convenient to operate, reliable in clamping, accurate in positioning, and capable of effectively improving maintenance efficiency while protecting the plane part.

Description

technical field [0001] The invention is a compound type small deep hole blind hole broken nail removal device suitable for repairing machine parts in the field of high precision machinery. Background technique [0002] In the field of high-precision machinery, the diameter of the screw holes for fastening electronic components is very small, and the ratio of depth to diameter is about 13:1. When disassembling electronic components, it is very easy for the screw to break in the hole, and it needs to be taken out and broken in a small deep blind hole. The screws in it can only be repaired. At present, the method used to remove the screws in small deep blind holes is to use tools such as fixtures, height gauges, vernier calipers, marking needles, positioning tools and other tools to position and then drill holes. Using this method cannot ensure the stable installation of parts, and it is harmful to the operator's skills. The level requirements are high, the probability of erro...
