Abstract
The invention discloses a processing method of a middle joint pipe. Transverse lengthening claws (1) are respectively welded on three hard claws of a machine tool triangular chuck; a moving centre on a machine tool tailstock is refitted to a rotatable moving triangular chuck (3); then one end of the middle joint pipe (2) is gripped into the three lengthening claws (1), and the other end of the middle joint pipe (2) is gripped into a machine tool tailstock triangular chuck (3e); the machine tool triangular chuck and the tailstock triangular chuck are screwed by using chuck keys; and the middle joint pipe is closely propped up by three claws of the triangular chucks on the two sides of the middle joint pipe; a machine tool spindle is started to drive the middle joint pipe to rotate, afterwards, a machine tool carriage (4) is moved to drive a tool rest (5) to move, a flange spigot (6) at one end of the middle joint pipe is firstly processed by using a cutting tool on the tool rest, and then the tool rest is moved to process a flange spigot at the other end of the middle joint pipe until the processing is completed. By adopting the method disclosed by the invention, the middle joint pipe can be mounted and clamped quickly, and the processing can be completed only through once mounting and clamping; after the flange spigot at one end of the middle joint pipe is processed, the middle joint pipe does not need to be turned around, and an operator only needs to move the tool rest and further process the flange spigot at the other end of the middle joint pipe, so the parallelism and the concentricity of the processed spigots at the two ends of the middle joint pipe can be guaranteed, the operation is simple, and the efficiency and the work piece processing precision are high.
Description
Technical field
The present invention relates to the processing method technical field of the middle adapter of chemical pump under the major axis liquid.
Background technology
Middle adapter is the part that chemical pump connects the pump housing and bearing body under a kind of YPL, the YH liquid, and the seam required precision on the ring flange of butt tube two ends is higher, particularly the concentricity and the depth of parallelism.Existing processing method, a kind of is on boring machine, to process, process the seam of taking over an end after, need the rotation boring table to turn around to process the seam of taking over the other end, the back of turning around is difficult for guaranteeing the concentricity and the depth of parallelism; Another kind is two stomidiums that prop up middle adapter with the flange of two band taperings; In the middle of flange, wear an axle core, an end of axle core is tight with the triangle clamp head-clamp, and the other end holds out against with the thimble on the tailstock; Because the restriction of tapering flange is taken over two ends Flange Plane lathe tool and is advanced not go.The operating efficiency of two kinds of methods is all very low, and is difficult for guaranteeing the geometric accuracy of turning part.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of above-mentioned existing processing method, and a kind of high-efficiency machining method that is easy to process and can guarantee middle adapter two end flanges seam geometric accuracies is provided.
The objective of the invention is to realize through following technical scheme.
A kind of processing method of middle adapter, procedure of processing is following:
(1) on three hard pawls of lathe triangle chuck, welds one section horizontal lengthening pawl respectively; Movable thimble on the tailstock tool is adapted as rotatable bolt cam chuck, and said bolt cam chuck comprises can be installed on cup dolly on the tailstock tool through the thimble section, be installed on bearing, footing in the base is installed on disk in the bearing, is installed on the tailstock triangle chuck on the disk;
(2) middle adapter one end is clamped in three lengthening pawls, the other end clamps in the tailstock tool triangle chuck;
The lathe triangle clamp head and tail seat tripod chuck that (3) will be positioned at the middle adapter two ends is screwed with chuck key, and three of the triangle chuck pawls are with the middle adapter stretching to both sides;
(4) start machine tool chief axis, drive middle adapter and rotate, move the lathe saddle then, drive knife rest and move, with the flange seam of processing middle adapter one end earlier of the cutter on the knife rest, follow rest again, the flange seam of the processing other end is until machining.
Three lengthening pawls of the present invention adopt the 45# steel to do, and mainly are to be welded to each other performance preferably for three hard pawls with lathe triangle chuck have.
Adopt processing method of the present invention, the clamping method of middle adapter is quick, and is that a clamping just can be accomplished processing; After processing the flange seam of middle adapter one end, need not reverse end for end, only need the flange seam of the follow rest reprocessing middle adapter other end to get final product middle adapter; The depth of parallelism and the concentricity of the two ends seam that can guarantee to process; Simple to operate, efficient is high, and the workpiece machining accuracy is high.
Further set forth content of the present invention below in conjunction with Figure of description.

The specific embodiment
As shown in Figure 1, a kind of processing method of middle adapter, procedure of processing is following:
(1) on three hard pawls of lathe triangle chuck, welds one section horizontal lengthening pawl 1 respectively; Movable thimble on the tailstock tool is adapted as rotatable bolt cam chuck 3, and said bolt cam chuck 3 comprises can be installed on cup dolly 3b on the tailstock tool through thimble section 3a, be installed on bearing 3c, footing in the base is installed on disk 3d in the bearing, is installed on the tailstock triangle chuck 3e on the disk;
(2) middle adapter 2 one ends pincers as shown in Figure 3 are gone in three lengthening pawls 1, other end pincers as shown in Figure 4 are gone in the tailstock tool triangle chuck 3e;
The lathe triangle clamp head and tail seat tripod chuck that (3) will be positioned at middle adapter 2 two ends is screwed with chuck key, and three pawls of both sides triangle chuck are with the middle adapter stretching;
(4) start machine tool chief axis, drive middle adapter 2 and rotate, move lathe saddle 4 then; Drive knife rest 5 and move, with the flange seam 6 of the elder generation of the cutter on knife rest processing middle adapter one end, follow rest again; The flange seam of the processing other end is until machining.
Three lengthening pawls 1 of the present invention adopt the 45# steel to do, and are welded in respectively on three hard pawls of lathe triangle chuck.
Adopt the inventive method; Because middle adapter is promptly no longer mobile behind a clamping location; Realize processing through follow rest, can guarantee the uniformity of the two end flanges seam concentricitys and the depth of parallelism, improve the geometric accuracy of middle adapter two ends seam middle adapter two end flanges seams; And simple to operate, working (machining) efficiency is high.
