Description

Shielding motor rotor keyway and hole machined positioner

Technical field:

The utility model relates to a kind of positioner when manufacturing shielding motor rotor keyway and hole machined.

Background technology:

The rotor of shield electric machine is the core of whole motor, it is the heart of motor, rotor is after roughing, on the cover of one end of rotor, a segment length is 400, wall thickness is the auxiliary impeller (auxiliary impeller state is now exactly a thin-walled bobbin) of about 30, auxiliary impeller and rotor are hot jackets, and after hot jacket, hoop is tightly extremely on rotor, are equivalent to one.After above process is assembled all on request, just can start the radial cross bore on the keyway of processing rotor side and auxiliary impeller, the radial cross bore of auxiliary impeller communicates with the centre bore of the axis of rotor, just that is, cross bore must bore from the surface of auxiliary impeller, bores thoroughly to bottom always.Keyway is axial, and cross bore is radial.After processing a through hole, rotor 90-degree rotation must be processed another through hole afterwards.The invention of this cover instrument, can only be simple when holing before compensate for by lathe, the primitive method measured by bevel protractor is processed, and the error of 90 degree between holes after processing is very greatly, causes very large trouble to lower sequence.

Summary of the invention:

The purpose of this utility model is open a kind of shielding motor rotor keyway and hole machined positioner.Its structure is simple, and easy to operate, the degree of accuracy of processing is high, and improves working (machining) efficiency.By the design of this instrument, the angular error occurred when solving long-term processing keyway and hole exceeds the scope that drawing controls, and ensure that the quality of the rear rotor of processing.Technical scheme is: by lifting axe (1), roller (2), pivot pin (3), raise block (4), locking nut (5), L-type closing block (6), screw (7), jack-up nut (8), V-block (9), handle (10), bearing (11), base (12), positioning key (13), connecting pin (14), holding out against screw (15) fixed arm (16) and form, two bearings (11) are vertically fixed on base (12), positioning key (13) is connected with fixed arm (16), fixed arm (16) is connected with one of them bearing (11) by connecting pin (14), connecting pin (14) is held out against with holding out against screw (15), fixed arm (16) is provided with two handles (10), V-block (9) is vertically fixed on base (12), two L-types are separately fixed at conjunction block (6) left and right sides of V-block (9) with screw (7), roller (2) with raise block (4) and be connected by pivot pin (3), the both wings raising block (4) insert L-type closing in block (6), lifting axe (1) screws in jack-up nut (8), locking nut (5) screws in lifting axe (1).

Operation principle:

The utility model by lifting axe (1), roller (2), pivot pin (3), raise block (4), locking nut (5), L-type closing block (6), screw (7), jack-up nut (8), V-block (9), handle (10), bearing (11), base (12), positioning key (13), connecting pin (14), holding out against screw (15) fixed arm (16) and form, roller (2) is connected to pivot pin (3) to be raised in block (4), the thickness of roller (2) with raise block (4) the tolerance of groove reserved be 0.5mm, be convenient to radial vibration, the outer diameter tolerance gap of roller (2) endoporus and pivot pin (3) is 0.1mm, shearing force for the power be subject to pivot pin (3) like this, and pivot pin will select steel alloy, and heat-treat, the both wings raising block (4) stretch in L-type closing in block (6), L-type is equivalent to define a up and down slideway closing block (6), this slideway is 1mm with the difference in height of the both wings raising block, be convenient to slide, raise block (4) freely up and down to move in slideway, the power moved freely mainly moves up and down in jack-up nut (8) by lifting axe (1), drive and raise block (4) and move up and down, after moving to roller (2) contact upper rotor part, lifting axe (1) is standby dead with locking nut (5), because lifting axe can move up and down, until roller contact is to rotor, at this moment be directly inserted in the keyway that product processed under the rotarily driving of handle (10) with the fixed arm (16) of positioning key (13), coordinating of keyway and key is just in time the angle of required machining hole, like this, in the radial direction of rotor, the free degree has been controlled completely, the axial free degree separately has other device, the key of end and hole can be processed like this, this cover positioner just serves effective control to the location of rotor radial.

The beneficial effects of the utility model are: the structure of this positioner is simple, easy for installation, workman is easy to operation, this device has versatility simultaneously, lifting axe when versatility is embodied in this device of rotor of different-diameter, only needs to change lower fixed arm and positioning key, because can drive and raise block and move up and down, roller just can move up and down simultaneously, adapts to the rotor of different diameters.And dismounting is also very convenient, saves material, easily manufacture, we adopt the roller of consumable accessory is steel alloy, so, can be good at meeting instructions for use with this instrument.
