Description
Technical field
The utility model relates to a kind of impeller assembling and uses frock, is applicable to that transition and slight interference amount cooperate the installation of impeller and motor shaft.
Background technology
In the prior art; Impeller has following several kinds of mounting means commonly used usually with axle in blower fan, the pump class: a kind of is to knock installation with copper rod or other instruments; But because the profile of impeller is frivolous and material is softer, installation is easy to impeller is caused damage in this way; Also have through the mode of heating impeller or freezing axle and install, but these modes make impeller and axle produce distortion because of temperature shock easily, thereby influence functions of the equipments.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide a kind of impeller assembling simple in structure, that can under the situation that guarantees impeller profile safety, assemble smoothly with motor shaft to use frock.
The utility model solves the technical scheme that its technical problem adopted: frock is used in described impeller assembling, and it is characterized in that: comprise screw mandrel, rotary body and compression plate, screw mandrel one end is the tool holding end; The other end is an axle link, the external screw thread that is connected with motor shaft spindle nose screwed hole that the axle link has independent processing, and rotary body is installed at the screw mandrel middle part; Rotary body is connected with wire rod thread; The rotary body top is the tool holding end, and the rotary body periphery is provided with annular groove, and compression plate comprises the linking arm on disk body and disk body top; Holding screw is installed on the linking arm; The holding screw head is arranged in annular groove, and disk body is positioned at rotary body below, installed thrust ball bearing between disk body and the rotary body.
In this frock, the axle link of screw mandrel is one section external screw thread of processing separately, be used for being connected with motor shaft with threaded hole, and through the tool holding end of tool holding screw mandrel, and in the screwed hole with the axle link screw-in motor shaft spindle nose of screw mandrel; In the process that rotary body drive compression plate moves down, through thrust ball bearing compression plate is not rotated, prevent the wearing and tearing that the compression plate rotation causes impeller in the assembling process; Position through holding screw between compression plate and the rotary body, on the one hand, rotary body comes off in the time of can preventing that frock from moving; On the other hand, because bearing is a consumable accessory, when bearing wear, only rotary body back-outed, taken off to need with holding screw, bearing changed to get final product then, and is easy to maintenance.
During work; Impeller vertically is placed on the motor shaft locatees, handheld tool is connected the external screw thread of screw axis link earlier and screws with the screwed hole of motor shaft spindle nose, then with tool holding and reverse the tool holding end of rotary body; Rotary body is moved axially; Compression plate moves down under the drive of rotary body, through compression plate impeller is pressed into motor shaft, thereby accomplishes the assembling of impeller and motor shaft.After each impeller installs, rotate rotary body, make frock come back to original position.
Wherein:
The seat ring of said thrust ball bearing and compression plate disk body interference fit, blowout patche and rotary body interference fit.
The tool holding end of described screw mandrel is a square head.
The tool holding end on described rotary body top is six square toes.The tool holding end of rotary body selects the specifications design of plain nut to get final product, and need not buy the torque spanner of special size specially, and is easy to operate.
The beneficial effect that the utility model had is:
The assembling of this impeller utilizes the original screwed hole of motor shaft spindle nose as the compression fit basis with frock, has avoided the design of fixtures such as claw, has reduced volume; The structural design advantages of simple drives compression plate through rotary body and moves down, and can impeller is assemblied on the motor shaft and guarantee that impeller does not deform, and guarantees the normal use of impeller and motor shaft; Rotary body and compression plate be through holding screw location, and rotary body comes off in the time of can preventing that frock from moving, and is convenient to the maintain and replace of bearing.
Description of drawings
Fig. 1 is the structural representation of the utility model under the original state;
Fig. 2 is the structural representation of the utility model after impeller and motor shaft assembling are accomplished.
Among the figure: 1, tool holding end; 2, screw mandrel; 3, rotary body; 4, annular groove; 5, holding screw; 6, linking arm; 7, thrust ball bearing; 8, disk body; 9, axle link; 10, impeller; 11, motor shaft spindle nose.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Like Fig. 1, shown in 2, frock is used in the impeller assembling, comprises screw mandrel 2, rotary body 3 and compression plate; Screw mandrel 2 one ends are tool holding end 1, and the other end is an axle link 9, the external screw thread that is connected with motor shaft spindle nose 11 screwed holes that axle link 9 has independent processing; Rotary body 3 is installed at screw mandrel 2 middle parts, and rotary body 3 is threaded with screw mandrel 2, and rotary body 3 tops are the tool holding end; Rotary body 3 peripheries are provided with annular groove 4, and compression plate comprises the linking arm 6 on disk body 8 and disk body 8 tops, and holding screw 5 is installed on the linking arm 6; Holding screw 5 heads are arranged in annular groove 4, and disk body 8 is positioned at rotary body 3 belows, installed thrust ball bearing 7 between disk body 8 and the rotary body 3.
Wherein: the tool holding end 1 of screw mandrel 2 is square heads; Rotary body 3 is the modifier treatment of 45# steel, and the tool holding end on rotary body 3 tops is six square toes, and six square toes select the specifications design of plain nut to get final product, and uses the promptly rotatable rotary body 3 of common torque spanner; The compression plate material is Q235A; Thrust ball bearing 7 is common thrust ball bearing.The seat ring of thrust ball bearing 7 and compression plate disk body 8 interference fit; Blowout patche and rotary body 3 interference fit; Screw mandrel 2 and rotary body 3 threaded engagement; After the above assembled steel ball and retainer are inserted seat ring, directly install the holding screw 5 of screwing on according to rotary body 3 and compression plate, this frock promptly connects and finishes.
During work; Impeller 10 vertically is placed on the motor shaft locatees, handheld tool is connected the external screw thread of 2 links 9 of screw mandrel earlier and screws with the screwed hole of motor shaft spindle nose 11, then with the torque spanner clamping and reverse the tool holding end of rotary body 3; Rotary body 3 is moved axially; Compression plate moves down under the drive of rotary body 3, through compression plate impeller 10 is pressed into motor shaft, thereby accomplishes the assembling of impeller 10 and motor shaft.After each impeller 10 installs, rotate rotary body 3, make frock come back to original position.Because compression plate does not rotate, can guarantee that therefore impeller 10 does not have wearing and tearing in the assembling process in folding process.
When bearing wear, only rotary body 3 back-outed, taken off to need with holding screw 5, bearing changed to get final product then, and is easy to maintenance.
