Abstract
The utility model relates to an impeller subassembly dynamic balance test anchor clamps belongs to tooling technical field. It includes mandrel 2, be located 2 one end in the mandrel and with the solid fixed cone body of mandrel structure as an organic whole 1, with 2 other end swing joint's in the mandrel the activity cone 3 and the fastening nut 4 of fastening activity cone 3. The utility model discloses can make things convenient for, stable clamping impeller subassembly, realized the uniformity of impeller subassembly clamping benchmark and test fixture location benchmark, the impeller subassembly is concentric with test fixture promptly to and impeller subassembly dynamic balance test's stability and accuracy have been guaranteed.
Description
Technical field
The utility model relates to impeller assembly dynamic balance testing fixture, belongs to equipment Technology field.
Background technology
In rotary machine, " balance " technology is the key technology of relation life of product and reliability, is the important guarantee that rotary machine reaches fine quality.In impeller assembly production process, dynamic balance running is absolutely necessary operation, when dynamic balance running is carried out to complicated impeller assembly 5 as shown in Figure 4, current employing conventional mandrel formula dynamic balance testing fixture 6 clamping impeller assembly 5 as shown in Figure 5, it is using the inner cylinder face of impeller assembly 5 as positioning datum, this benchmark and axle formula fixture matched in clearance, be the contact point of certain local in cylindrical cross-section in theory, form contact wire on cylinder to center, but because each clamping state is different, contact wire is also different, and namely embodied center situation is also different.Due to tolerance, the concentricity impact of two ends locating hole, fit clearance is little, then axle and two ends locating hole probably interfere; If fit clearance is large, then the dynamic balancing measurement of the amount of unbalance caused by fit-up gap to impeller assembly causes interference; Even if adopt high accuracy microgap axle to coordinate with part, due to impeller axle endoporus manufacturing tolerance, need to do more than ten single mandrel, when using at the scene, multiple axle can select to testing crew and trial assembly causes puzzlement.Above-mentioned axle formula dynamic balance testing fixture affects by factors such as fit-up gaps, can not simulated impeller assembly central axis state very well, cause stablizing and measure impeller assembly amount of unbalance, also just its amount of unbalance can not be corrected further, the high accuracy dynamic balance performance requirement of impeller assembly cannot be realized, and there is clamping difficulty, test fixture to shortcomings such as many, the dynamic balance running poor repeatability of balancing a survey interference.
Summary of the invention
In view of the foregoing defects the prior art has, the utility model aims to provide a kind of complicated impeller assembly dynamic balance running clamping difficulty, test fixture of can solving to the impeller assembly dynamic balance testing fixture of many, the dynamic balance running poor repeatability of balancing a survey interference.
To achieve these goals, the utility model is by the following technical solutions: dynamic balance of impeller test fixture, comprises axle, is positioned at axle one end and the clamp nut of the fixing cone, the activity cone be flexibly connected with the axle other end and the fastening activity cone that are structure as a whole with axle.
Described axle and activity cone material adopt CrWMn.
Compared with the prior art, the utility model is owing to have employed technique scheme, can facilitate, stable clamping impeller assembly, achieve the uniformity of impeller assembly clamping benchmark and test fixture positioning datum, namely impeller assembly is concentric with test fixture, thus and ensure that stability and the accuracy of impeller assembly dynamic balance running.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Fig. 1 ~ 2: dynamic balance of impeller test fixture comprises axle 2, be positioned at one end of axle 2 and the clamp nut 4 of the fixing cone 1, the activity cone 3 be flexibly connected with axle 2 other end and the fastening activity cone 3 that are structure as a whole with axle.In order to make axle, activity cone wear-resisting, not yielding, improve its service life, described axle 2 and activity cone 3 adopt CrWMn to process, and carry out HRC58 ~ 62 heat treatment.
In order to correct the dynamic balancing of fixture before dynamic balance running, manufacture auxiliary socket 7 as shown in Figure 3, the impeller assembly of simulate ideal state is assemblied in the state on dynamic balance testing fixture.This sleeve is assemblied on dynamic balance testing fixture and measures imbalance, and carry out disequilibrium regulating at the non-installation locating surface of test fixture, realize the high-quality dynamic balance performance of fixture.
