The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and be described with reference to the accompanying drawings as follows:
See also accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8.
Embodiment
A kind of processing method of special-shaped workpiece adopts the frock mode to process, and first frock is assemblied on lathe, carries out the frock centering, then workpiece is assemblied on frock, the fastening rear special-shaped workpiece processing of carrying out on lathe.It is motionless that workpiece machines rear frock, and the dismounting workpiece carries out new workpiece processing.Pipeline system is adopted in workpiece processing, and A and B frock are arranged on two lathes, and when workpiece was assemblied on frock, frock was provided with the locating shaft corresponding with workpiece or keyway.When workpiece is assemblied on frock, with bolt with workpiece and frock are fastening put together on together with.
Concrete design and process are as follows:
1, the design of frock:
Operating position by this part can be known, the C shape groove that this workpiece uses the position to locate for " working position-B ".High-speed rod passes through in this C shape groove, these workpiece 3 blanks are that the QT800 essence is cast work, dimensional accuracy is very high, and this C shape groove inside dimension and do not require processing, design frock so select the inboard of this C shape groove as positioning datum, process " working position-A ", the Fixture Design scheme as shown in Figure 2.Select a φ 60mm according to the size of C shape groove, the axle of long 1000mm positions, and an auxiliary corresponding base 1-1 is used for and locating shaft 1-2 and lay workpiece, as shown in Figure 2.Why select the bolt handle and mode stationary positioned axle and do not select the mode that is welded and fixed, reason is to consider that welding deformation can be on affecting the precision of frock.
This frock is " 1# frock ", this 1# frock 1 mainly by base 1-1, locating shaft 1-2, close bolt 1-3, several parts such as locking briquetting 1-4, clamping screw 1-5 form, non-standard all obtains by processing method, has so just guaranteed the required precision of frock.
Required frock is as shown in Figure 4 when " working position-B " in processing, " working position-A " survives at this moment, the frock of this step is mainly to have utilized to process the semicircle cambered surface that survives and position for benchmark, consider that the mutual changing of the relative positions may occur for workpiece 3 and frock, utilizing has these characteristics of a keyway on workpiece 3, added a positioning key on semiaxis.So just, guaranteed the precision of the relative position size of workpiece.This frock is " 2# frock ", and 2# frock 2 is by base 2-1, positioning half-axle 2-2, partly form closing bolt 2-3, hold-down bolt 2-4, positioning key 2-5 etc., still adopt the bolt handle and mode fix the location and use semiaxis, guaranteed the required precision of frock.
2, process:
Above-mentioned frock has been arranged, and the processing of this workpiece just can realize on common boring machine.The processing at A, B two positions is placed on different equipment carries out, at first frock is installed to and adjusts centering on equipment, later each workpiece loading and unloading, frock is motionless, saved a large amount of centering time, adopted the mode of pipelining to process, and then reduce unnecessary expenditure of time, increase work efficiency, shorten the process-cycle.
The processing at " A position ", at first workpiece is installed on " 1# frock ", the use state sees accompanying drawing 1, accompanying drawing 5 for details, consider between locating shaft and C shape groove gapped, require when therefore being installed centering a side and the tooling shaft of C shape groove are close to, later on each workpiece is all that same position and tooling shaft are close to and get final product, and procedure of processing is as follows:
A. mill and upper cover handle and contact-making surface, 1.5mm ladder platform is not first processed, and mills closing the bolt plane, protects size 50;
B. bore 13 of 10-φ and bolt hole;
C. lead upper cover, bolt, nut, packing ring and handle and install, two places, boring A position φ 110 hole become;
D. shed upper cover, mill the 120 wide axle bed 1.5mm of place ladder platforms and 14H9 keyway.
The processing at " B position " is installed on workpiece on " 2# frock ", and the use state sees accompanying drawing 3, accompanying drawing 6 for details, and centering is with four machined surfaces one-tenth of molding cutter processing C shape groove edge position.
