Description
Technical Field
The invention relates to a repair tool, in particular to a repair tool for the assembly size of a steering knuckle bushing.
Background
In the production field of steering knuckle, some holes need to install the bush, and the fitting dimension of steering knuckle and bush generally has clear and definite regulation, but because the reasons such as the not hard up of frock, wearing and tearing in the installation, often can cause the fitting dimension out of tolerance, this direct influence whether can assemble smoothly in the assembly. At present, a tool for repairing the assembly out-of-tolerance size is not available.
Disclosure of Invention
The invention aims to provide a repairing tool for the assembling size of a steering knuckle bushing, which repairs the unqualified assembling unqualified size of a steering knuckle and the bushing in use.
In order to achieve the purpose, the technical scheme of the invention is as follows: a repairing tool for the assembly size of a steering knuckle bushing comprises a nut (1), a gasket (2), a positioning sleeve (3), a jackscrew (4), a pressing sleeve (5), a bolt (6) and a fixing sleeve (7); the upper end of the positioning sleeve (3) is conical, the lower end of the positioning sleeve is a plane, and the middle of the positioning sleeve is provided with a hole; the excircle of the positioning sleeve (3) is matched with the inner hole of the extruding sleeve (5); the jackscrew (4) is fixed on the extruding sleeve (5), and the output end of the jackscrew is matched with an open slot on the positioning sleeve (3); the gasket (2) is arranged at the lower ends of the positioning sleeve (3) and the extruding sleeve (5); the lower end face of the fixed sleeve (7) is contacted with the upper end face of the knuckle workpiece, and the bore diameter of an inner bore of the fixed sleeve (7) is larger than the outer diameter of the bushing; the bolt (6) penetrates through the gasket (2), the positioning sleeve (3) and the inner hole of the fixing sleeve (7) to be matched with the nut (1), and the nut (1) is arranged at the lower end of the gasket (2).
In one embodiment, the bolt (6) is a hex bolt.
When in actual use, the fixed sleeve is arranged on the upper end surface of the steering knuckle workpiece; arranging the extruding sleeve on the lower end surface of the steering knuckle workpiece; the cone above the positioning sleeve is matched with the excircle of the inner tube of the steering knuckle bushing to realize the positioning of the extrusion sleeve; placing the gasket at the lower ends of the positioning sleeve and the extruding sleeve; the bolt passes through the gasket, the positioning sleeve and the inner hole of the fixing sleeve to be matched with the nut; the bolt and the nut are screwed tightly by using a spanner, and the upper end of the extrusion sleeve is matched with the lower end surface of the outer pipe of the steering knuckle bushing; and jacking up the steering knuckle bushing under the action of the pulling force of the bolt, so that the assembling size of the steering knuckle bushing is changed.
The invention can repair the unqualified assembly dimension of the steering knuckle and the bushing in use; meanwhile, the device has the characteristics of simple structure, low manufacturing cost, convenience in operation, strong universality and the like.
