Abstract

The invention relates to a method for processing a large arc surface. The method comprises the steps that a bottom plate is fixedly mounted on a workbench of a machine tool; an oscillating plate is placed above the bottom plate; the bottom plate is connected with the oscillating plate by a rotating shaft; one end of a connecting shaft is fixedly connected with a side face of the oscillating plate and the other end thereof serves as a supporting point of a tooling and is fixed; a workpiece to be processed is clamped on the oscillating plate to allow the distance from the to-be-processed side face of the workpiece to the supporting point to be equal to the radius of the workpiece to be processed; after the machine tool begins operating, the workbench makes reciprocating motion; the oscillating plate drives the workpiece to swing relative to the bottom plate around the rotating shaft and make arc motion around the supporting point; and a planer tool on the machine tool planes the arc surface on the to-be-processed side face of the workpiece.

Description

A kind of method of processing the great circle cambered surface

Technical field

The present invention relates to metallurgical machinery and make field, particularly a kind of method of processing the great circle cambered surface.

Background technology

All great circle cambered surface workpiece as shown in Figure 1 are one of parts common in the machinery production process.In prior art, the general using CNC planer type milling machine is processed great circle cambered surface workpiece, but the machined task of CNC planer type milling machine is at full stretch, usually can't in time be processed, and affects production process, and processing cost is very high.

Summary of the invention

When the object of the invention is to overcome prior art and utilizing CNC planer type milling machine processing great circle cambered surface workpiece processing cost high, the defective such as can't in time process, can process the method for great circle cambered surface workpiece thereby provide a kind of on common lathe.

To achieve these goals, the invention provides a kind of method of processing the great circle cambered surface, comprising:

Step 1), on the workbench 5 of a lathe base plate 6 of fixed installation, place again an oscillating deck 7 above described base plate 6, between described base plate 6 and described oscillating deck 7, employing rotating shaft 8 is connected;

Step 2), an end of described connecting axle 10 is fixedly connected with a side of described oscillating deck 7, the other end of described connecting axle 10 fulcrum 11 as frock is maintained static;

Step 3), on described oscillating deck 7 clamping workpiece 9 to be processed, make the side to be processed of described workpiece 9 and the distance between described fulcrum 11 equal the radius of workpiece 9 to be processed;

After step 4), described lathe are started working, workbench 5 moves reciprocatingly, described oscillating deck 7 drives described workpiece 9 and swings around the relatively described base plate 6 of described rotating shaft 8, simultaneously do circular motion around described fulcrum 11, the planing tool 12 on described lathe digs arc surface 2 in the side to be processed of described workpiece 9.

In technique scheme, described lathe is metal-planing machine.

The invention has the advantages that:

Method of the present invention can realize need not the processing of great circle cambered surface workpiece by CNC planer type milling machine on common lathe, has effectively reduced cost, has improved operating efficiency.

The specific embodiment

Now the invention will be further described by reference to the accompanying drawings.

The basic principle of Machining Arc face is on workpiece: the arc surface of considering workpiece belongs to the surface of revolution, and the cutting movement of the relative workpiece of cutter is combined with the gyration of workpiece, can realize the processing to the workpiece circular arc face.

In the present embodiment, take metal-planing machine as example, how to utilize metal-planing machine processing great circle cambered surface workpiece to be described to the inventive method, in other embodiments, the inventive method also can be used for the lathe such as the other types of milling machine.

As shown in Figure 2, the correlation step of method of the present invention is as follows:

Step 1), on the workbench 5 of metal-planing machine base plate 6 of fixed installation, place again an oscillating deck 7 above described base plate 6, between described base plate 6 and described oscillating deck 7, employing rotating shaft 8 is connected.

Step 2), an end of connecting axle 10 is fixedly connected with a side of described oscillating deck 7, the other end of described connecting axle 10 fulcrum 11 as frock is maintained static.

Step 3), on oscillating deck 7 clamping workpiece 9 to be processed, make the side to be processed of described workpiece 9 and the distance between described fulcrum 11 equal the radius R of workpiece 9 to be processed.

After step 4), metal-planing machine are started working, workbench 5 moves reciprocatingly, described oscillating deck 7 drives workpiece 9 and swings around the relative base plate 6 of rotating shaft 8, does circular motion around fulcrum 11 simultaneously, and the planing tool 12 on metal-planing machine just can dig arc surface 2 in the side to be processed of workpiece 9.

Fig. 3 and Fig. 4 have done exemplary illustration to utilizing the inventive method to process great circle cambered surface workpiece on metal-planing machine.As shown in Figure 3, workbench in the position for the moment, A point 13 on cutter 12 cutting workpieces 9, as shown in Figure 4, workbench is when position two, connecting axle 10 and oscillating deck 7 drive workpiece 9 anglecs of rotation 15, and oscillating deck 7 drives workpiece 9 and swings around the relative base plate 6 of rotating shaft 8, and cutter 12 cutting workpieces 9 are in B point 14 positions.See from Fig. 3 and Fig. 4, cutter 12 marks a circular arc line 2 to the B point at workpiece 9 from the A point, and the radius 3 of this circular arc line is exactly the design radial R of workpiece 9.

It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described.Although with reference to embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, technical scheme of the present invention is modified or is equal to replacement, do not break away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
