Description
Technical field
The utility model relates to a kind of supercharger compression impellor dynamic balance testing device, particularly a kind of blind hole compression impellor tilting dynamic balance testing device.
Background technology
Compression impellor is the essential core part of supercharger, duty is High Rotation Speed state, therefore higher requirement for dynamic balance is had to it, in the manufacture and repair process of impeller, dynamic balancing measurement must be carried out to impeller, dynamic balancing machine being found out impeller non-equilibrium site and unbalance mass, by increasing the weight of in non-equilibrium site or the method for duplicate removal, making its unbalance residual content meet designing requirement.
For the transient equilibrium of blind hole compression impellor, due to its design feature, assembly connection mostly adopts and is threaded, and rectifying plane is apart from little, usually adopts the outer center of gravity cantilever support mode of horizontal type level dynamic balancing machine at present.Also vertical balancing machine and horizontal type balancing machine can be adopted to carry out combined test by iso standard adopts said method to carry out dynamic balancing measurement, there is following deficiency: 1) adopt and be threaded, it is unreliable to locate, and affects impeller measuring accuracy, does not reach permissible accuracy grade.2) outer center of gravity cantilever support mode, very high to the manufacture requirements of frock mandrel, and run not steady, affects the measuring accuracy of impeller.3) each transient equilibrium, install, dismantle inconvenience, production efficiency is low.4) carry out combined test, although can reach requirement, need two kinds of equipment, two cover frocks, complex process, production cost is high, and efficiency is low.
Utility model content
For solving the problem, the utility model provides a kind of blind hole compression impellor tilting dynamic balance testing device, overcomes existing blind hole impeller dynamic balancing measurement mode and locates unreliable, that operation is steady, production efficiency is low deficiency.
For achieving the above object, blind hole compression impellor tilting dynamic balance testing device of the present utility model, comprise fixed cover, reducing sleeve and mandrel, one end of described fixed cover connects a compressed air joint, the other end is enclosed within described reducing sleeve, and is fixed by gib screw; Described reducing sleeve is enclosed within one end of described mandrel, and is fixed by stop screw; The blind hole of described blind hole compression impellor is enclosed within the other end of described mandrel, and described blind hole compression impellor can rotate around described mandrel; Pressurized air enters in fixed cover by described compressed air joint, then enters in the blind hole of described blind hole compression impellor along reducing sleeve and mandrel; The rotation of described blind hole compression impellor is with respect to the horizontal plane inclined upwardly.
Preferably, described mandrel is arranged in the part of the blind hole of described blind hole compression impellor is triangular prism shape.
Preferably, the belt friction that is rotated through of described blind hole compression impellor drives.
By blind hole compression impellor tilting dynamic balance testing device of the present utility model, can carry out the dynamic balancing measurement of blind hole compression impellor easily, fast and accurately, and operate steadily, production efficiency improves.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of blind hole compression impellor tilting dynamic balance testing device of the present utility model.
Embodiment
Be described in further details below in conjunction with the embodiment of accompanying drawing to blind hole compression impellor tilting dynamic balance testing device of the present utility model.
See Fig. 1, blind hole compression impellor tilting dynamic balance testing device of the present utility model, comprise fixed cover 8, reducing sleeve 9 and mandrel 10, one end of described fixed cover 8 connects a compressed air joint (not shown), the other end is enclosed within described reducing sleeve 9, and is fixed by gib screw 11; Described reducing sleeve 9 is enclosed within one end of described mandrel 10, and is fixed by stop screw 12; The blind hole of described blind hole compression impellor 1 is enclosed within the other end of described mandrel 10, and described blind hole compression impellor 1 can rotate around described mandrel 10; Pressurized air enters in fixed cover 8 by described compressed air joint, then enters along reducing sleeve 9 and mandrel 10 in the blind hole of described blind hole compression impellor 1.Adopt blind hole compression impellor 1 to rotate around mandrel 10, solve due to frock run steadily and frock amount of unbalance and screw thread locate impact on impeller balance precision.Connect pressurized air by mandrel 10, make impeller 1 be in suspended state in mandrel 10 rotary course, reduce parts depreciation, increase traveling comfort.
The rotation 2 of described blind hole compression impellor 1 with respect to the horizontal plane 3 to be inclined upwardly an angle [alpha].The size of angle [alpha] can select about 15 °.Rotation 2 and surface level 3 at angle, correspondingly, fixed cover 8, reducing sleeve 9 and mandrel 10 axially also with surface level 3 tilt angle alpha.Adopt the mode of inclination, it is a kind of support pattern between horizontal type balancing machine and vertical balancing machine, be equivalent to once to complete and adopt vertical balancing machine and horizontal type balancing machine to carry out combined test, the calculating parameter of test macro should carry out converting according to the actual measurement size of angle [alpha], adjusts, solidify.
The shape that described mandrel 10 is arranged in the part of the blind hole of described blind hole compression impellor 1 is triangular prism shape, and this special construction is felt relieved, and is convenient to lubricating oil and compressed-air actuated input.Described mandrel 10 is positioned at the blind hole clearance fit of described blind hole compression impellor 1, and can realize fast quick-mounting, tear impeller open, repeatable accuracy is high, and production efficiency is high.
The rotation of described blind hole compression impellor 1 can be driven through angle [alpha] break-in (not shown) by belt, belt drives along the large cylindrical both sides friction of blind hole compression impellor 1, belt compresses and unclamps conversion conveniently, and the size of clamping force is shown by pressure gauge, steadily stressed, easily duplicate removal position can be placed in position upward, dead ahead, be convenient on lathe duplicate removal or increase the weight of, directly perceived, accurately, efficient.
Before carrying out blind hole compression impellor 1 dynamic balancing measurement, first fixed cover 8, reducing sleeve 9 and mandrel 10 are installed, fixed cover 8 is fixed on a base, and reducing sleeve 9 can be different different according to the model of blind hole compression impellor 1 with the size of mandrel 10.After installing fixed cover 8, reducing sleeve 9 and mandrel 10, connect compressed air joint, adjust compressed-air actuated pressure, impeller 1 blind hole is cleaned and is oilyly placed on mandrel 10, and the large cylindrical both sides of belt and blind hole compression impellor 1 are compressed in opposite directions, can balance test be carried out.Other servicing units of test can adopt device identical in prior art.
After test terminates, non-equilibrium site can being placed in upper end, dead ahead according to display, lathe can carry out duplicate removal or increase the weight of, removing metal fillings by siphoning away at the suction cleaner of dynamic balance testing device lower end.Blind hole compression impellor 1 is in test rotation process, and be full of pressurized air between blind hole and mandrel 10, resistance is little, operates steadily, and the wearing and tearing of impeller blind hole are very little, do not destroy its dimensional accuracy.Utilize the utility model can carry out dynamic balancing measurement and the verification of blind hole compression impellor easily, fast and accurately.
Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
