Description
Technical field:
The present invention relates to the top clamping device of one two that processing in machine-building has the axial workpiece multiple operation use of axially extending bore, specifically a kind of axle multiple operation pretightening technology blocks up.
Background technology:
At present, in tradition manufactures, a lot of axial workpiece axle center is had to be designed with through hole for oiling, such as a kind of mining gipsy sheave axle, have rough turn in mechanical processing process, finish turning, corase grind, milling spline, spline quenches, fine grinding six large operations must with two top clampings, but just first must need get out the axially extending bore of φ 70 before modified, then through hole two ends are processed into the hole platform of φ 85 × 60, reprocess the disposable technique extremely stifled (getting out center hole) that two are of a size of interference, loaded in two stomidium platforms of axle extremely stifled for technique, to carry out two top clamping manufacturing procedures, after above operation to be done, technique is extremely stifled to be difficult to unload, can only fall by bit drills.Traditional handicraft is extremely stifled is single use, and the stifled waste of material of system is serious, and system is stifled, dress is stifled and it is stifled more when taking platform to tear open, and production efficiency is low, and labour intensity is large, so can not meet the need of production of current cost efficiency.
Summary of the invention:
In order to solve above-mentioned Problems existing, it is high that patent of the present invention provides a kind of positioning precision, and process of transfer order does not come off, two top clamping and positioning devices of convenient disassembly, recycling, reduce spillage of material and non-cutting time, not only alleviate the labour intensity of operator, also improve operating efficiency.
The technical solution adopted in the present invention utilizes the swelling function of expansion set in the hole platform inner position of axle and fastening, invented again pretension lid and made it keep tension force not come off, utilized again the acting in opposition of pretension lid to dismantle this device after all process steps to be done.Its concrete structure is made up of pretension lid 1, expansion set 2, inner core 3;
Pretension lid 1 bore design has internal thread D and tension hook B, and cylindrical is designed to annular knurl face and four wrench slot E; Internal thread D is screwed by left and right and pretension lid can be made to move forward and backward, and the effect of tension hook B is that the pretension platform A straining expansion set 2 makes it keep expansive force; Cylindrical annular knurl adds frictional force, conveniently screws during pretension; Wrench slot E is the position oppositely exerted a force when unloading stifled; Expansion set 2 is also designed with positioning table C, is used for contacting with the Kong Tai outer face of axle carrying out axial location; One end of inner core 3 processes place's concave station, play the effect of loss of weight and protection center hole, axial design has through hole and two center holes, and through hole is used for issuable steam and oil smoke in heat treatment step evacuation aperture, and the outer bowlder that center hole is used for clamping workpiece or fine grinding expansion set 2 uses; After device combination, the left-handed pretension platform A that strains of pretension lid 1 keeps expansive force, and dextrorotation can be loosened pretension platform A and discharge expansive force, and this sample device just can be implemented in the function of carrying out pretension and dismounting in axis hole.
The beneficial effect of patent of the present invention is: avoid the problem of resource waste that the disposable technique in traditional work is extremely blocked up, and solves and in use needs clamping firmly and the technology barrier of convenient disassembly; And simple to operate, dependable performance, this device can realize mounting and dismounting on workpiece fast, but also can reuse, and is especially suitable for the batch production needing to raise the efficiency.

Detailed description of the invention
The present invention is made up of pretension lid 1, expansion set 2, inner core 3; Pretension lid 1 bore design has internal thread D and tension hook B, and cylindrical is designed to annular knurl face and four wrench slot E; Internal thread D is screwed by left and right and pretension lid 1 can be made to move forward and backward, and the effect of tension hook B is that the pretension platform A straining expansion set 2 makes it keep expansive force; Expansion set 2 is also designed with positioning table C, is used for contacting with the Kong Tai outer face of axle carrying out axial location; One end of inner core 3 processes place's concave station, play the effect of loss of weight and protection center hole, axial design has through hole and two center holes, and through hole is used for issuable steam and oil smoke in heat treatment step evacuation aperture, and the outer bowlder that center hole is used for clamping workpiece or fine grinding expansion set 2 uses; After device combination, the left-handed pretension platform A that strains of pretension lid 1 keeps expansive force, and dextrorotation can be loosened pretension platform A and discharge expansive force, and this sample device just can be implemented in the function of carrying out pretension and dismounting in axis hole.
Specific works process is as follows:
When this technique is blocked up and manufactured, expansion set 2 Excircle machining is to Φ 79.9mm ~ Φ 79.95mm.
1, axle holes platform internal diameter size is machined to Φ 80.2mm ~ Φ 80.3mm, such axle multiple operation pretightening technology is stifled just can easily be installed in the platform of hole, and expansion set 2 positioning table C is contacted with Kong Tai outer face.
2, two ends install the stifled axle of axle multiple operation pretightening technology be installed to lathe two top on, then tailstock centre is held out against, because stifled core 3 is subject to two top thrusts, and then props up expansion set 2 and make its swelling in axis hole.
3, at this moment, with hand, pretension lid 1 is screwed left, make it retreat, until tension hook B and pretension platform A contact, so just can keep the tightening state of expansion set 2, process operation normally.
4, a procedure complete after in process of transfer order, because tension hook B and pretension platform A strains, axle multiple operation pretightening technology blocks up by solid and reliable pretension in axis hole, can transport normally and the processing of other operations.
5, the operation of the top clamping of all needs two should be laid down axle multiple operation pretightening technology after all completing and blocked up, method applies to the wrench slot E of pretension lid 1 power that screws to the right, make it move forward, at this moment tension hook B is separated with pretension platform A, to expansion set 2 keep pretightning force also along with disappearance, continue to screw pretension lid 1 end face of its right-hand member and axle to be extruded produce reaction force, be easy to like this to make stifled core 3 rollback, expansion set 2 resets, then axle is easily taken out with multiple operation pretightening technology is stifled, clean for subsequent use.
Axle multiple operation pretightening technology blocks up in manufacture process, and stifled core 3 adopts match grinding to process with expansion set 2, and contact performance is good, by pretension lid 1 suitably pretension after assembling, then expansion set 2 cylindrical is worn into, and ensures that stifled core 3 centre bore is concentric with expansion set 2 cylindrical.Use the top thrust of middle lathe that stifled core 3 is moved forward, make expansion set 2 stretching inner bore of part by cone structure, when pretension lid 1 pretension ensures to turn sequence, axle multiple operation pretightening technology is stifled can not loosen.When unloading stifled, dextrorotation pretension lid 1 makes it move forward, until the end face of engagement shaft, utilizes the reaction force of internal thread D to make stifled core 3 rollback, loosen expansion set 2 take out axle multiple operation pretightening technology block up.
