Abstract
The utility model discloses a special frock of festival segmentation multistage centrifugal pump interchangeability, including locating plate, bushing plate, bolt, U type clamp plate, adjusting screw, hexagon nut, locating lever, spring, location strip, the one end of bushing plate is connected with the top of locating plate is perpendicular, and U type clamp plate passes through the bolt fastening at the other end of bushing plate, and adjusting screw passes through hexagon nut to be fixed in the bottom of locating plate and link to each other with the locating lever, and the locating lever passes through spring coupling location. This special frock easy operation is convenient, in industry the commonality wide, can correct size skew behind the lathe work guarantee the interchangeability in part flange hole, make reliable error little, make easy, structure and size precision stable, has greatly improved this area and has leaded to non -interchangeable problem because of flange joint hole size nonconformity.
Description
Technical field
The utility model relates to sectional multi-stage centrifugal pump and manufactures field, particularly a kind of centrifugal multistage pump multiple centrifugal pump inlet segment and water exit end flange connecting hole interchangeability special tooling.
Background technology
The impact of the interchangeability that part flange hole connects concentrates on the part exchanging in service of goods process most, because part non-CNC processing causes dimensional discrepancy finally to cause part to change causing the replacing of whole collection dress part, affect the satisfaction of client, add the hardware cost of client.Current processing method mainly contains following several: (1) single drill jig controlled working.The axial dimension that the method accurately can control each hole is same benchmark, and can ensure that the connecting hole benchmark of ring flange is same, the accurate size for connection of size positions accurately and reliably.But radial dimension controls without benchmark, interchangeability is not strong.(2) manual controlled working of ruling.The axial dimension in each hole of the method energy basic controlling is same benchmark, but manual setting-out benchmark searching center is higher to employee's complex art Capability Requirement, and accuracy controlling is also more difficult.
Summary of the invention
All own limitations is there is based on existing manufacture method, for solving the problem of existing centrifugal multistage pump multiple centrifugal pump interchangeability work, the purpose of this utility model is the special tooling for carrying out manufacturing processing to sectional multi-stage centrifugal pump water-in and water-out section flange connecting hole providing a kind of simple and convenient.
For achieving the above object, the utility model provides following technical scheme:
Sectional multi-stage centrifugal pump interchangeability special tooling, comprise location-plate, bushing plate, bolt, U-shaped pressing plate, adjusting screw(rod), hex nut, backstay, spring, positioning strip, one end of bushing plate is connected with the plan vertical of location-plate, U-shaped pressing plate is bolted on the other end of bushing plate, adjusting screw(rod) is fixed on the bottom of location-plate by hex nut and is connected with backstay, and backstay connects positioning strip by spring.
Preferably, bushing plate is fixedly connected with by hexagon socket cap head screw with the top of location-plate.
Sectional multi-stage centrifugal pump interchangeability special tooling of the present utility model has following beneficial effect: (1) is simple to operate, can be used by single bolt presses.(2) regulated by spring, the interchangeability that the size offset after turnery processing ensures part flange hole can be corrected.This special tooling is simple to operation, in industry versatility wide, turnery processing can be corrected after size offset ensure part flange hole interchangeability, manufacture that reliable error is little, easy to manufacture, structure and dimensional accuracy stablize, greatly improve this area and cause non-interchangeable problem because Flange joint hole dimension is inconsistent.This special tooling is applicable to batch production and waits complex parts to measure.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, simple introduction is done below by the accompanying drawing used required in embodiment or description of the prior art, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Accompanying drawing 2 is the left view of the utility model embodiment.
In accompanying drawing, 1, location-plate; 2, hexagon socket cap head screw; 3, bushing plate; 4, bolt; 5, U-shaped pressing plate; 6, adjusting screw(rod); 7, hex nut; 8, backstay 9, spring; 10, positioning strip.
Detailed description of the invention
Below by specific embodiment, the utility model is further described.
A kind of sectional multi-stage centrifugal pump interchangeability special tooling, as shown in Figures 1 and 2, comprise location-plate 1, bushing plate 3, bolt 4, U-shaped pressing plate 5, adjusting screw(rod) 6, hex nut 7, backstay 8, spring 9, positioning strip 10, one end of bushing plate 3 is connected with the plan vertical of location-plate 1, U-shaped pressing plate 5 is fixed on the other end of bushing plate 3 by bolt 4, adjusting screw(rod) 6 is fixed on the bottom of location-plate 1 by hex nut 7 and is connected with backstay 8, and backstay 8 connects positioning strip 10 by spring 9.
Wherein, bushing plate 3 is fixedly connected with by hexagon socket cap head screw 2 with the top of location-plate 1.
Have axial dimension positioning spigot bottom bushing plate 3, control axial dimension, backstay 8 is for controlling radial dimension, and positioning strip 10 is with processing plane is by flat, and dependence spring 9 regulates, backstay 8 locating element plane seam.Bushing plate 3 hole centre-to-centre spacing and detail drawing completely the same.
Specific implementation method of the present utility model is: be first placed in by Special drilling jig (sectional multi-stage centrifugal pump water-in and water-out section flange) on the part that need process, the positioning spigot of alignment flange, then regulate vertical by spring 9 with positioning strip 10, backstay 8 plane seam location radial symmetric, is fixed on Special drilling jig on flange to be drilled finally by bolt 4, U-shaped pressing plate 5.
In factory's actual production, demonstrate this Special drilling jig frock by reviewer's service condition feasible.This its advantage of Special drilling jig frock: simple to operation, in industry versatility wide, turnery processing can be corrected after size offset ensure part flange hole interchangeability, manufacture that reliable error is little, easy to manufacture, structure and dimensional accuracy stablize, greatly improve this area and cause non-interchangeable problem because Flange joint hole dimension is inconsistent.This Special drilling jig frock is applicable to batch production and waits complex parts to measure.
Apply specific embodiment herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.The above is only preferred embodiment of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite not departing from the utility model principle, some improvement, retouching or change can also be made, also above-mentioned technical characteristic can be combined by rights; These improve retouching, change or combination, or the design of utility model and technical scheme are directly applied to other occasion without improving, and all should be considered as protection domain of the present utility model.
