Description
Technical field
The utility model relates to segmentation centrifugal multistage pump multiple centrifugal pump system regions, particularly pump housing sole hole drill tool locating instrument.
Background technology
For meeting different customer demands, centrifugal multistage pump multiple centrifugal pump complete machine pump housing interchangeability problem need be solved.To install in conjunction with sectional type multi-stage pump and pump body structure is analyzed, meet the pump housing and exchange and need meet the axial installation dimension of flange center and sole, flange level, vertical and sole center size and flange hole position degree size.
Following problem is always there is at present: (1) processing pump housing class part datum level is larger to runner errors of centration in pump housing manufacture process.Now add and measure blank die joint with depth gauge rule man-hour, the requirement of this method to blank is higher, and finds runner center difficulty accurately, and because present stage part blank cannot reach requirement, therefore finished size error is larger.(2) sole hole is to pump housing datum clamp face axial dimension and sole hole radial dimension (centre-to-centre spacing).Sole hole radial dimension (centre-to-centre spacing) is with sole blank side for benchmark, and manual line, it is consistent that this method is difficult to reach each part, and scale error is large.
Above problem causes in pump housing process, and operating personnel rely on experience determination drill center positional precision, and expend time in long and rule inconvenient, machining accuracy can not effectively be ensured.
Summary of the invention
For solving the problems referred to above of existing centrifugal multistage pump multiple centrifugal pump pump housing boring, the purpose of this utility model is to provide one can improve operating efficiency and accuracy, and handled easily personnel carry out the sectional multi-stage centrifugal pump pump housing sole hole drill tool locating instrument of ruling.
For achieving the above object, the following technical scheme of the utility model: sectional multi-stage centrifugal pump pump housing sole hole drill tool locating instrument, comprise bushing plate, hex nut, plain washer, guide post, spring, backstay, alignment pin, positioning strip, bushing plate is connected with backstay is vertical, the other end of backstay is connected with positioning strip is vertical, bushing plate is also vertically connected with guide post, the other end of guide post is connected with positioning strip is vertical, the junction of backstay and bushing plate is provided with spring, and positioning strip two ends are provided with alignment pin.
Preferably, the junction of bushing plate, positioning strip, guide post, backstay is fixed by hex nut and plain washer.
Preferably, described guide post is two, lays respectively at the both sides of backstay.
Pump housing drill tooling orientation tool of the present utility model has following beneficial effect: (1) adopts this drill tooling orientation tool to avoid operating personnel to determine drill center position and manual line by hand, substantially increase operating efficiency, reduce operating personnel's skill set requirements; (2), after pump housing sole hole drill tool positioning device is fixed, drill center position is determined automatically, ensure that bore position precision; (3) structure is simple, easy for installation.
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 is bushing plate, and 2 is hex nut, and 3 is guide post, and 4 is spring, and 5 is backstay, and 6 is alignment pin, and 7 is positioning strip.
Detailed description of the invention
Below by specific embodiment, the utility model is further described.
Sectional multi-stage centrifugal pump pump housing sole hole drill tool locating instrument as shown in Figures 1 and 2, comprise bushing plate 1, hex nut 2, plain washer, guide post 3, spring 4, backstay 5, alignment pin 6, positioning strip 7, bushing plate 1 is connected with backstay 5 is vertical, the other end of backstay 5 is connected with positioning strip 7 is vertical, bushing plate 1 is also vertically connected with guide post 3, the other end of guide post 3 is connected with positioning strip 7 is vertical, backstay 5 is provided with spring 4 with the junction of bushing plate 1, and positioning strip 7 two ends are provided with alignment pin 6.Wherein, the junction of bushing plate 1, positioning strip 7, guide post 3, backstay 5 is fixed by hex nut 2 and plain washer.Wherein, guide post 3 is two, lays respectively at the both sides of backstay 5.
In the utility model, sole hole site is determined by bushing plate 1, and backstay 5, alignment pin 6, positioning strip 7 and guide post 3 play the role of positioning.Each positioner and bushing plate 1 are connected and fixed by hex nut 2 and plain washer.With positioning strip 7 by flat datum clamp face, two alignment pins 6 are felt relieved, and guarantee sole center and axis, radial dimension meets drawing requirement.Take off Special positioning tool after sample punching marks and bore sole hole.
Specific implementation process of the present utility model is: in drill tooling hole, alignment pin 6 position during processing pump housing mating surface, and by positioning strip 7 alignment pin 6 stationary positioned bar 7, limit levels direction is moved and circumferencial direction rotates.Backstay 5 and guide post 3 will make vertical direction fix, and move up and down distance by regulating spring 4 compression ratio determination bushing plate 1, determine sole center and hole site axially, radial dimension is consistent with design drawing.
This novel practical structure is simple, on existing sectional multi-stage centrifugal pump pump body structure, provides a kind of efficient, easy, reliable sole hole drill tool locating tool solution.
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.
