Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of pipe fitting to be processed.
As shown in Fig. 2~7, a kind of pipe fitting indexes processing unit (plant), mainly includes:Upper cover plate 1, left location nut 2, the right side Location nut 3, left-hand thread pin 4, right-hand thread pin 5, left positioning compression component 6, right positioning compression component 7, rotary index head assembly 8th, contracting block assembly 9, tie down screw 10, ring flange 11, connection component 12, lower cover 13, pedestal 14 are compressed.Upper cover plate 1 is located at bottom The top of seat 14, is correspondingly arranged with lower cover 13, is fixed by screws on pedestal 14.Left location nut 2, right location nut 3 are fixed on by left-hand thread pin 4, right-hand thread pin 5 between left positioning compression component 6, right positioning compression component 7 and lower cover 13. Rotary index head assembly 8 compresses the upper and lower ends that contracting block assembly 9 is correspondingly arranged at pedestal 14 respectively.Tie down screw 10 is with compressing Contracting block assembly 9 is arranged side by side, and contracting block assembly 9 is compressed for radially locking.Ring flange 11 passes through connection component 12 and machine tool chief axis It links together, the tapered structure in one end of ring flange 11, taper is 15 degree.Connection component 12 connects spiral shell by 4~8 interior hexagonals Nail composition.
Wherein:Left positioning compression component 6 is identical with right 7 structure of positioning compression component, is symmetrically arranged at rotary index The opposite end of head assembly 8.It is made of V-arrangement briquetting 15, positioning pin 1, positioning pin 2 17, clamping screw 18.V-arrangement briquetting 15 are fixed on the end of clamping screw 18 by positioning pin 1, positioning pin 2 17.As shown in Figure 8, Figure 9.
Rotary index head assembly 8 is made of bearing 1, bearing 2 20, push-down head 21, locating piece 22.Bearing 1, axis The 2 20 one end outer surfaces for being sleeved on push-down head 21 successively are held, locating piece 22 clamps the other end for being fixed on push-down head 21.Such as Shown in Figure 10, Figure 11.
Contracting block assembly 9 is compressed to be made of pressure head 23, seaming chuck 24, bearing 3 25, bearing 4 26, compression slide bar 27.Upper pressure First 24 are sleeved on one end of pressure head 23, and bearing 3 25, bearing 4 26 are sleeved on successively on seaming chuck 24, and compress 27 sets of slide bar Mounted in the outer surface of bearing 3 25, bearing 4 26.As shown in Figure 12 and Figure 13.
During processing, first pass through connection component 12 and this processing unit (plant) and lathe spindle fastening are connected together, then pass through spiral shell Nail 14 center of adjustment base and lathe spindle coincide.The compression compressed by 10 drivening piece of tie down screw in contracting block assembly 9 is slided Bar 27 is driven, and the seaming chuck 24 in compression contracting block assembly 9 is made to move down together with the locating piece 22 in rotary index head assembly 8 Workpiece to be added is compressed, then positioning processing is carried out by left positioning compression component 6 and right positioning compression component 7 compression.When processing Pipe fitting one end makes left positioning compression component 6 be unclamped with right positioning compression component 7, and 90 ° of rotations are carried out to rotary index head assembly 8 Turn(Rotary index head assembly 8 can be made the indexing of other angles by the needs according to finished product exemplified by 90 ° herein), Zhi Houzai It is secondary that positioning processing second end is carried out by left positioning compression component 6 and right positioning compression component 7;When pipe fitting has on the same face Processing method when three ends or four ends equally using second end is processed.When processing a batch, stringency block is pressed by replacing Locating piece 22 matches with pipe fitting to be processed in pressure head 23 and rotary index head assembly 8 in component 9, carries out adding for new product Work.
In the processing technology of pipe fitting, indexing processing unit (plant) can be big compared with existing conventional brace manually by the present invention The time of big reduction part in process, and by replaceable pressure head and locating piece with regard to more specification products can be carried out Processing can effectively reduce the quantity of fixture, reduce fixture cost, while can also improve the position degree requirement of product.With it is existing Automatic indexing chuck compare, since existing automatic indexing is higher to equipment requirement, be typically necessary customization special purpose machine tool;And this Requirement of the invention processing unit (plant) to equipment is relatively low, and can be added by being transformed use to existing lathe in machine Industrial and commercial bank's industry is widely popularized and applies.
