Abstract

The invention relates to a technique for machining ultra-long spring parts by using a center lathe. The technique comprises the following steps: 1) clamping and fixing a central spindle by using a triangular chuck of the center lathe, and fixing one end of a spring steel wire at one end of the central spindle; 2) starting a lathe spindle until the spring steel wire cannot twine continuously, and stopping; 3) placing a gasket on the outer circumference of the tail end of a spring, and covering a clamp main body outside the gasket, wherein a bolt penetrates through the upper part of the clamp main body to tightly lean against the gasket; 4) loosening the triangular chuck of the center lathe, and inserting the central spindle into a spindle box, wherein a knife rest also moves synchronously; 5) twining the spring steel wire 1 on the central spindle 2 continuously until the spring steel wire 1 cannot twine continuously, and then fixing the clamp main body again; 6) repeating the fifth and sixth steps until the spring parts with the lengths according with technological requirements are machined. The technique is simple and easy to operate, the dependence on equipment can be reasonably and effectively reduced, the labor intensity of operators is reduced, and the work efficiency is improved.

Description

Use the process of engine lathe processing super long spring part

Technical field

The present invention relates to a kind of process of using engine lathe processing super long spring part, for processed springs length, exceed the process of spring Coil-up of effective workspace of engine lathe.

Background technology

At present, the effective workspace of engine lathe is limited, cannot use engine lathe by common process method processing length, to exceed the spring part of the effective workspace of engine lathe.The type spring is mainly used spring Coil-up machined, but purchase of equipment investment cost is large in advance, during use the tool setting time longer, and need frequent tool setting guarantee spring part technological requirement, cause spring part manufacturing cost to increase.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of process of using engine lathe processing super long spring part, and this process is simple, easy to operate, can rationally effectively reduce equipment is relied on, and reduces operator's labour intensity, increases work efficiency.

For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of process of using engine lathe processing super long spring part, comprises the following steps:

1) with the triangle chuck of engine lathe, mandrel is fixedly clamped; A termination of spring steel wire is fixed on to mandrel one end;

2) start lathe spindle, mandrel rotation, is wound into spring steel wire on mandrel, until spring steel wire cannot continue to be wound around, stops;

3) pad is placed on the excircle of spring tail end, and in the outer cover of pad, has the circular arc jig main body of hatch frame, jig main body top holds out against through screw and pad;

4) unclamp the triangle chuck of engine lathe, the spring fixing is together inserted in main spindle box together with mandrel, jig main body is exposed outside triangle chuck, at the process intermediate slide inserting also synchronizing moving; After insertion completes, the position parcel copper sheet contacting with triangle chuck at the excircle of spring, then clamps mandrel by triangle chuck;

5) continue spring steel wire 1 to be wound on mandrel 2, until cannot continue to be wound around, then unclamp the bolt on jig main body, pad, jig main body are together moved to the spring tail end of new winding, and again fix jig main body;

6) repeating step 4 and 5, until process the spring part that meets technological requirement length.

The process of this processing super long spring part adopts above-mentioned steps, can use engine lathe to process the spring part that length exceeds the effective workspace of engine lathe, so just avoided the dependence of non-spring Coil-up machine equipment, also significantly reduced simultaneously operator labour intensity, improved operating efficiency, reduced the processing cost of part.

The specific embodiment

A process of using engine lathe processing super long spring part, comprises the following steps:

1) with the triangle chuck of engine lathe, mandrel 2 is fixedly clamped, wherein the length of mandrel 2 is greater than the total length of spring to be processed; A termination of spring steel wire 1 is fixed on to mandrel 2 one end;

2) start lathe spindle, mandrel rotation, is wound into spring steel wire 1 on mandrel 2, until spring steel wire cannot continue to be wound around, arrives effective workspace of lathe, then stops;

3) pad 3 is placed on the excircle of spring tail end, and in the outer cover of pad 3, there is the circular arc jig main body 4 of hatch frame, as shown in Figure 1, jig main body 4 tops hold out against through screw and pad 3, as shown in Figure 2, its Intermediate gasket 3 plays the effect of protection spring, and jig main body 4, for the spring having twined is fixed, makes spring steel wire 1 in the freely activity of spring tail end;

4) unclamp the triangle chuck of engine lathe, the spring fixing is together inserted in main spindle box together with mandrel, jig main body 4 is exposed outside triangle chuck, at the process intermediate slide inserting also synchronizing moving, thus the uniformity of assurance spring pitch; After insertion completes, the position parcel copper sheet contacting with triangle chuck at the excircle of spring, in order to avoid crush spring, then clamps mandrel by triangle chuck;

5) as shown in Figure 3, continue spring steel wire 1 to be wound on mandrel 2, until cannot continue to be wound around, then unclamp the bolt on jig main body 4, pad, jig main body 4 are together moved to the spring tail end of new winding, and again fix jig main body 4;
