background technology:
have three kinds of parts in metal structure product, be respectively A part, B part and C part, wherein A part and C part are the assemblies become by multiple part welding equipment, and B part is single part.Three kinds of parts are with bolts, and the kind in the hole that is connected is many, A assembly has 22 M10 screws, 6 Φ 56 holes; B part there are 22 Φ 11 holes, 6 Φ 60 holes; C assembly there are 6 Φ 38 holes.Wherein 22 M10 screws of A assembly are connected with a Φ 11 hole, 22 on B part bolt; 6 Φ 56 holes on A assembly are connected with 6 Φ 38 hole bolts on a Φ 60 hole, 6 on B part and C assembly.Type of attachment is: A-B, A-B-C.To ensure during manufacture that three kinds of parts are interconnected the pitch tolerance in hole, the concentricity in the hole that namely will ensure to be connected.Because the kind in hole is many, the quantity in hole is many, if adopt the method for line boring according to a conventional method, can not meet part at all and connect required precision.
utility model content:
the purpose of this utility model is to provide and a kind ofly ensures the multiple connected fitting of the different pore size of hole concentricity.
above-mentioned object is realized by following technical scheme:
a kind ofly ensure the multiple connected fitting of the different pore size of hole concentricity, its composition comprises: assembly A, part B, assembly C, bushing plate, described assembly A is processed with unthreaded hole one and screwed hole, described part B is processed with unthreaded hole two, unthreaded hole three, described assembly C is processed with unthreaded hole four, described bushing plate has unthreaded hole five and unthreaded hole six, described assembly A and described part B is threaded connection, and described assembly A, described part B are connected with bolt with described assembly C.
the multiple connected fitting of different pore size of described guarantee hole concentricity, described bushing plate is separately fixed on described assembly A, described part B and described assembly C, and the bottom of described bushing plate is connected with support member.
the multiple connected fitting of different pore size of described guarantee hole concentricity, described unthreaded hole one, described unthreaded hole two, described unthreaded hole three, described unthreaded hole four, can for identical aperture also can be different apertures.Described unthreaded hole five and described unthreaded hole six determine aperture size according to demand.
the multiple connected fitting of different pore size of described guarantee hole concentricity, the assembly that described assembly A is become by multiple part welding equipment with described assembly C, described part B is single part.
the beneficial effects of the utility model:
1. the utility model technique adopts bushing plate processing method, and because the diameter of each connector aperture is different, it is thorough that the selection of the bore dia of bushing plate will be considered.Determine using part B as reference design bushing plate by analysis, aperture is by the minimum aperture design of the fitting that is connected, namely the thread Pilot hole Φ 8.5 of 22 Φ 11 holes assembly AM10 screw designs, the Φ 38 hole design on C assembly is pressed in 6 Φ 60 holes, the specification of bushing plate is 22 Φ 8.5 holes and 6 Φ 38 holes, and drill jig positioning datum is part symmetrical center line and centerline hole.Assembly A and part B first uses bushing plate prebored hole respectively, and then respectively reaming or thread mill drilling to figure paper size; Assembly C with bushing plate time processing Φ 38 hole to figure paper size.
to the multiple connected fitting of different pore size, the utility model ensures that the processing of hole concentricity provides a kind of brand-new thinking, easy to process, effectively ensure that the hole machined concentricity of the multiple connected fitting of different pore size, ensure that assembling parts connects precision, crudy is good, and production efficiency is high.
