Embodiment Construction

[0019] The present invention will be further described below in conjunction with drawings and embodiments.

[0020] Such as Figure 1 ~ Figure 4 As shown, the present invention includes a plurality of support rods 1, a plurality of connecting sleeves 2, a plurality of sets of brush assemblies 3 and a plurality of elastic support mechanisms 4, and each set of brush assemblies 3 is arranged in parallel on the support rod 1 in pairs and up and down. Outside the side. The support rod 1 of this embodiment is a quadrangular prism structure with a square cross-section. Two groups of four brush assemblies 3 are evenly distributed on the four sides of the support rod 1 . The elastic supporting mechanism 4 in the hole 11 is connected, and the two groups of brush assemblies 3 are longitudinally staggered and the axes intersect at 90°. This embodiment is used to clean the main oil passage hole 5 of Φ100mm aperture of the L27 / 38 type marine diesel engine. There are two groups of four bru...

Abstract

The invention discloses a wire falling-prevention combined brush for cleaning deep holes. The wire falling-prevention combined brush comprises a plurality of support rods, a plurality of connecting sleeve pipes and a plurality of sets of brush assemblies. Every two brush assemblies in each set are arranged outside the two sides of the support rods in parallel in pairs in an up-down mode. The two ends of one set of brush assemblies are connected through an elastic supporting mechanism arranged in the support rods. The two sets of brush assemblies are longitudinally staggered and intersect axially. The support rods and at least two sets of brush assemblies arranged on the support rods form a combined brush unit. The support rods and connecting sleeve pipes of every two combined brush units are hinged through fastening pieces. The combined brush units and the connecting sleeve pipes are connected in a spaced mode to form the combined brush for cleaning the deep holes according to the required length. The wire falling-prevention combined brush for cleaning the deep holes solves the problem that the upper portion of the hole wall of a main lubricating oil duct of a diesel engine can not be cleaned up, the service life of a chimney steel brush is prolonged, the cleaning cost is reduced, and the deep hole cleaning efficiency is greatly improved.

Description

technical field [0001] The invention relates to a special cleaning brush for casting deep holes of castings, in particular to a combined brush that can effectively prevent wire brushes from detaching and improve the cleaning effect of casting deep holes, and belongs to the technical field of post-processing of castings. Background technique [0002] The cast ductile iron frame is one of the key parts of the diesel engine, and its processing quality directly affects the overall performance and service life of the diesel engine. For example, the main lubricating oil passage hole of the L27 / 38 marine diesel engine is directly cast in the frame, and the rough hole diameter of the main lubricating oil passage hole is Φ100mm. According to the power of the 6-9 cylinder diesel engine, the length of the main lubricating oil passage is from 4140mm ~5730mm range. The main lubricating oil passage hole also communicates with several through holes and process holes leading to the oil dis...
