Description
Technical field
This utility model relates to one and pulls out handler, and especially one is pulled out and unloaded aluminum covering device.
Background technology
It is provided with lining sometimes between bearing and housing in mechanical system, and aluminum lining is the most more common one
Kind.In work process, the situation of aluminum set abrasion often occurs, need to carry out pulling out by aluminum set unload maintenance or change.At present, pull out and unload aluminum
First set carries out tapping with the screw tap of major diameter at aluminum set internal diameter on machine tool, is screwed in by the screw tap being furnished with slidably sleeve
In aluminum set, a people firmly pins part, and another people sliding sleeve of repeatedly exerting oneself beats the step surface of screw tap tail end so that it is produce
Aluminum is overlapped and piecemeal extracts from part body by bigger impulsive force.This shortcoming pulling out set mode is to pull out favourable opposition during set
Power of hitting easily makes casing locating surface be deformed, labor strength big, it is high to pull out set special tooling manufacturing expense, and major diameter
During tap tapping, torsional forces is big, and when clamping force cannot meet, part security incident can easily occur with main axis.
Summary of the invention
The purpose of this utility model is to provide one and pulls out and unload aluminum covering device, have low cost of manufacture, simple to operate, laborsaving,
Safety, operating process do not destroy the feature of the original precision of part.
Concrete technical scheme of the present utility model is: pulls out and unloads aluminum covering device and include apotting spindle, lock-screw, tension spiral shell
Bolt, support, described apotting spindle is a Step Shaft, and the part being relatively large in diameter is arranged on aluminum to be unloaded and puts, the portion that diameter is less
Point be positioned at aluminum to be unloaded set and overlap internal diameter with aluminum to be unloaded and there is gap, apotting spindle centrally through screw thread, tension spiral shell is installed
Bolt, surrounding is provided with lock-screw, turnbuckle and lock-screw by screw thread and is axially arranged, and described lock-screw is
Multiple and be evenly arranged, and it is positioned at the position of apotting spindle minor diameter, being predominantly located on apotting spindle of lock-screw, little
Outside being partially exposed at, and it is engaged with aluminum to be unloaded set internal diameter；Described support is fixed on the matrix that aluminum to be unloaded set is installed, and strains spiral shell
Bolt one end is arranged on the center screw thread of apotting spindle, after the other end passes support, is provided with nut.Described support and nut
Between be provided with end face bearing.Described lock-screw is 6.
Apotting spindle in use, is first loaded aluminum to be unloaded and puts by this utility model, by lock-screw by the location heart
Being threaded into of axle, and be engaged with the inwall of aluminum to be unloaded set, aluminum to be unloaded set is tightened together with apotting spindle, then installs and prop up
Frame and turnbuckle, turn turnbuckle, apotting spindle and aluminum set are vertically extracted from part body.This utility model is using
Time, will not produce impulsive force, operate safety, mechanical part also will not be made to be deformed, and have only to an operator and can grasp
Make, laborsaving, simple to operate.Therefore, this utility model achieves that operative is simple, laborsaving, safety, and aluminum set is vertical from part body
In do not destroy the original precision of part, this design is simple and cheap for manufacturing cost.
The technical solution of the utility model is not limited to pulling out of aluminum set and unloads, it is also possible to expand to the bush structure of other material
In dismounting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of apotting spindle；
Fig. 3 is the top view of Fig. 2.
Detailed description of the invention
Unloading aluminum covering device include apotting spindle 2, lock-screw 3, turnbuckle 4, support 1 as it can be seen, pull out, described determines
Position mandrel 2 is a Step Shaft, and the part being relatively large in diameter is arranged on aluminum to be unloaded set 6, and the part that diameter is less is positioned at aluminum to be unloaded set 6
In and overlap 6 internal diameters with aluminum to be unloaded and there is gap, apotting spindle 2 centrally through screw thread, turnbuckle 4 is installed, surrounding passes through spiral shell
Stricture of vagina is provided with lock-screw 3, turnbuckle 4 and lock-screw 3 and is axially arranged, and described lock-screw 3 is multiple and equal
Even layout, and it is positioned at the position of apotting spindle 2 minor diameter, being predominantly located on apotting spindle 2 of lock-screw 3, fraction
Outside being exposed to, and overlap 6 internal diameters with aluminum to be unloaded and be engaged；Described support 1 is fixed on the matrix 7 that aluminum to be unloaded set is installed, and strains spiral shell
Bolt 3 one end is arranged on the center screw thread of apotting spindle 2, after the other end passes support 1, is provided with nut 8.Described support 1
And it is provided with end face bearing 5 between nut 8.Described lock-screw 3 is 6.
