Abstract
The invention discloses a locating device for motor test gear shrinkage fit. The locating device comprises a sample block, a locating screw, a locating frame, locking nuts and a fixing bolt. The locating frame is in an inverted U shape. The locating screw is screwed into the front end from the rear end of the locating frame in a penetrating manner. The sample block is arranged at the front end of the locating screw. The locking nuts are arranged at the rear end of the locating frame. The fixing bolt is screwed into the inner side from the outer side at the rear end of the locating frame. The locating device has the beneficial effects that sample blocks with different thicknesses are selected for different types of motors, so that it is guaranteed that the shrinkage fit amount of a test gear of the same type of motor accords with the process requirement and the shrinkage fit amount of test gears of all the types of motors are almost consistent, the reliability of test gear shrinkage fit is guaranteed, and therefore the phenomena that sliding and falling off happen in the test process of the test gear or disassembly cannot be achieved easily after the test and a motor rotary shaft and the test gear are damaged or scrapped are eliminated thoroughly.
Description
Technical field
The present invention relates to technical field of motors, particularly a kind of motor test gear hot jacket positioner.
Background technology
After existing direct current/pulse current electric motor test gear is heated to set point of temperature, direct hot jacket, in the rotating shaft of motor, does not has
Take other restriction or location measure with the amount of being inserted in of Control experiment gear.
Through practice, existing motor test gear hot jacket mode can cause the amount of the being inserted in difference of every motor test gear relatively
Greatly.When the amount of being inserted in is the least, test gear can slip and fall off in motor testing process, causes machine shaft and test gear to damage
Wound, it is impossible to complete test, the most also can cause machine shaft and test scrapping of gear；When the amount of being inserted in is the biggest, test gear
Dismounting the most highly difficult.
Therefore, it is highly desirable to existing motor test gear hot jacket mode is improved.
Summary of the invention
The goal of the invention of the present invention is: for the problem of above-mentioned existence, according to motor and the construction features of test gear,
A kind of motor test gear hot jacket positioner is provided.
The technical solution used in the present invention is such that
A kind of motor test gear hot jacket positioner, including sample block, positioning screw, locating rack, lock nut and fixing bolt,
Described locating rack is inverted U, and described positioning screw is threaded through front end from locating rack rear end, and described sample block is arranged on positioning screw
Front end, described lock nut is arranged on locating rack rear end, and described fixing bolt is screwed into inner side in locating rack rear end from outside.
As preferably, described locating rack rear end is higher than front end, and described fixing bolt is arranged on the rear end of locating rack.Locating rack
This preferred constructive form, can on the premise of reducing weight as far as possible, can guarantee that again bolt can be screwed into inner side
Test gear face is fixed.Locating rack can also use other positioning forms, e.g., between locating rack two end side panels away from
From adjustable, directly by side plate, test gear be clamped, and bolt need not be fixed, but the amount of being inserted in of this mode is consistent
Property is relatively poor.
As preferably, described lock nut has two, is arranged at locating rack rear end.The effect of two lock nuts is set
It is, prevents lock nut from unclamping and have influence on the amount of being inserted in of test gear.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
1, different types of motor, selects the sample block of different-thickness, thus ensures the test gear amount of being inserted in of same type motor
Meet technological requirement, and ensure that the amount of being inserted in of each type motor test gear is basically identical, it is ensured that test gear set
Reliability, thus stopped test gear occur slipping and falling off or having tested in process of the test after be difficult to remove phenomenon
And machine shaft and test gear destruction or the phenomenon scrapped；
2, directly this positioner is placed on and then tightens fixing bolt on test gear and got final product the clamping of back-to-back test gear
Action, simple to operate quickly.
Accompanying drawing explanation
Fig. 1 is the use view of the present invention.
Labelling in figure: 1 is sample block, 2 is positioning screw, and 3 is locating rack, and 4 is locking nut, and 5 is fixing bolt, and 6 is electricity
Machine seal ring, 7 is test gear, and 8 is machine shaft.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is described in detail.
Embodiment:
As it is shown in figure 1, a kind of motor test gear hot jacket positioner, including sample block 1, positioning screw 2, locating rack 3, locking spiral shell
Female 4 and fixing bolt 5, described locating rack 3 is inverted U, described positioning screw 2 from locating rack 3 one end through the other end, described sample
Block 1 is arranged on positioning screw 2 front end, and described lock nut 4 is arranged on locating rack 3 rear end, and described fixing bolt 5 is at locating rack 3
Rear end is screwed into inner side from outside.
Described locating rack 3 rear end is higher than front end, and described fixing bolt 5 is arranged on the rear end of locating rack 3.
Described lock nut 4 has two, is arranged at locating rack 3 rear end.
The operation principle of the present invention:
1, after the male cone (strobilus masculinus) of machine shaft 8 and the inner conical surface of test gear 7 being cleaned out, test gear 7 is touched in motor
In rotating shaft 8, such as accompanying drawing 1.
2, being put in by this positioner on test gear 7, positioning screw 2 is placed between adjacent two teeth of test gear 7, twists
Fasten bolt 5, thus this positioner is fixed on test gear 7.
3, between the head and the end face of motor seal ring 6 of positioning screw 2, this motor type defined amount of being inserted in (sample is put into
Block thickness=regulation amount of being inserted in) sample block 1.
4, positioning screw 2 is tightened, with the head of positioning screw 2, sample block 1 is pressed on the end face of motor seal ring 6.
5, tighten locking nut 4, prevent positioning screw 2 to be subjected to displacement.
6, unclamp fixing bolt 5, take off this positioner, test gear 7 is heated.
7, the test gear 7 after heating is placed on the male cone (strobilus masculinus) of machine shaft 8, this positioner is put in again test
On gear 7, and tighten fixing bolt 5.
8, the test gear 7 installing positioner is pushed into positioning screw 2 head to contact with motor seal ring 6.
9, after test gear 7 shrinks, unclamp fixing bolt 5, take off this positioner, the hot jacket work of test gear 7
So far complete.
