Abstract
The utility model relates to a kind of electric motor end cap relieving attachment, it by linking up with, crossbeam, screw mandrel, swivel nut, thrust bearing, pressing plate, determine screw and tight dog screw forms.The utility model compared with prior art has the following advantages: one, two hooks are adjustable, can adapt to the dismounting of various electric motor end caps; Two, screw mandrel and rotating shaft contact portion adopt thrust bearing, and pressing plate and spindle nose can not produce relative motion, avoid spindle nose to produce mechanical damage; Three, simple in structure, light and handy, low cost of manufacture, easy to use.
Description
Technical field
The utility model relates to a kind of electric motor end cap relieving attachment.
Background technology
Existing electric motor end cap is dismantled most of adopting process Bolt dismantling, and the relieving attachment also having adopts shaft central hole location.There is following shortcoming in these two kinds of dismounting modes: the former adopting process bolt level pressure support, and owing to not being to exert oneself simultaneously, discontinuity equalization, tends to cause end cap and support to produce mechanical damage; Although what the latter adopted is relieving attachment, owing to locating with shaft central hole, the screw mandrel in device and shaft central hole produce extruding, and the as easy as rolling off a log shaft central hole that makes produces mechanical damage, affects the positioning datum of whole armature.
Summary of the invention
The purpose of this utility model is to overcome the problem that above-mentioned prior art exists, and a kind of simple in structure, convenient disassembly is provided, to machine shaft, can cause machinery to damage
Wound and electric motor end cap relieving attachment cheaply.
The technical solution of the utility model is: a kind of electric motor end cap relieving attachment, is characterized in that this described electric motor end cap relieving attachment comprises hook, crossbeam, screw mandrel, holding screw, thrust bearing, dog screw, pressing plate and swivel nut;
Described hook is two L-type hooks that size is identical; These two L-type hooks are symmetricly set on crossbeam, link up with side and have installing hole, can on crossbeam, have by oneself and move, and can use the dismounting of various electric motor end caps; Hook top is provided with screw, and two hook symmetries are sleeved on crossbeam and by holding screw and position with fastening;
Described crossbeam two ends are circular configuration, and crossbeam interlude is square structure, have for the through hole of screw mandrel is installed on this crossbeam interlude, and swivel nut concentric is welded on the lead to the hole site of crossbeam interlude;
Described screw mandrel is tubular structure, and screw mandrel top is square structure, and screw mandrel lower end extends in swivel nut, and is connected with thrust bearing through the through hole of crossbeam interlude, and is connected with pressing plate by dog screw.
Described crossbeam two ends are circular configuration, are connected together with hook connecting, and mid portion is square structure, welds together with swivel nut;
The utility model compared with prior art has the following advantages: one, two hooks are adjustable, can adapt to the dismounting of various electric motor end caps; Two, screw mandrel and rotating shaft contact portion adopt thrust bearing, and pressing plate and spindle nose can not produce relative motion, avoid spindle nose to produce mechanical damage; Three, simple in structure, light and handy, low cost of manufacture, easy to use.

Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is screw mandrel lower end and thrust bearing and pressing plate assembly structure schematic diagram;
Fig. 3 is left TV structure schematic diagram of the present utility model;
In figure: 1-hook, 2-crossbeam, 3-screw mandrel, 4-holding screw, 5-thrust bearing, 6-dog screw, 7-pressing plate, 8-swivel nut.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of electric motor end cap relieving attachment, is characterized in that this described electric motor end cap relieving attachment comprises hook 1, crossbeam 2, screw mandrel 3, holding screw 4, thrust bearing 5, dog screw 6, pressing plate 7 and swivel nut 8;
Described hook 1 is two L-type hooks that size is identical; These two L-type hooks 1 are symmetricly set on crossbeam 2, link up with 1 side and have installing hole, and hook 1 top is provided with screw, and two hook 1 symmetries are sleeved on crossbeam 2 and by holding screw 4 and position with fastening;
Described crossbeam 2 two ends are circular configuration, and crossbeam 2 interludes are square structure, on these crossbeam 2 interludes, have for the through hole of screw mandrel 3 is installed, and swivel nut 8 concentrics are welded on the lead to the hole site of crossbeam 2 interludes;
Described screw mandrel 3 is tubular structure, and screw mandrel 3 tops are square structure, and screw mandrel 3 lower ends extend in swivel nut 8, and is connected with thrust bearing 5 through the through hole of crossbeam 2 interludes, and is connected with pressing plate 7 by dog screw 6.
The utility model operation principle: during dismounting electric motor end cap, hook 1 is hooked in to electric motor end cap cocked bead position or reinforcement position, rotary screw rod 3, pressing plate 7 is travelled forward until withstand machine shaft end face, then with spanner or round bar rotary screw rod 3, crossbeam 2 is constantly to screw mandrel 3 top-direction motions under the effect of screw mandrel 3, and two L-type hooks 1 also move to screw mandrel 3 top-direction thereupon together, thereby electric motor end cap is disassembled from support.
The utility model compared with prior art has the following advantages: one, two hooks are adjustable, can adapt to the dismounting of various electric motor end caps; Two, screw mandrel and rotating shaft contact portion adopt thrust bearing, and pressing plate and spindle nose can not produce relative motion, avoid spindle nose to produce mechanical damage; Three, simple in structure, light and handy, low cost of manufacture, easy to use.
