Summary of the invention
The technical problem that the utility model is short for the existing lathe life-span and range of application is little, provides the lathe with the floating mouth of rotation of length of a kind of life-span and applied range.
For this reason, the utility model is provided with floating mouth seat and rotates floating mouth, and floating mouth seat is arranged with bearing, and bearing is provided with both sides, and the side of bearing is provided with Front oil seal, and opposite side is provided with Rear oil seal; Rotate floating mouth and be provided with front gland and rear pressing cover, Front oil seal to be set on floating mouth seat and to be positioned at front gland; Front oil seal, Rear oil seal and front gland, rear pressing cover are all in circular, and the external diameter of Front oil seal is identical with the internal diameter of front gland, and the external diameter of Rear oil seal is identical with the internal diameter of rear pressing cover; Rotate floating mouth and be also provided with nut, nut is provided with internal thread, and floating mouth seat is provided with external screw thread, and the internal thread of nut and the external screw thread of floating mouth seat cooperatively interact; Rear oil seal is located at the periphery of nut.
Preferably, bearing is provided with fore bearing and rear bearing, and Front oil seal is located at the outside of fore bearing, and Rear oil seal is located at the outside of rear bearing, is also provided with inner ring and outer ring between fore bearing and rear bearing.
Preferably, inner ring to be set on floating mouth seat and to form interference fit, and outer ring is located at outside inner ring.
Preferably, the length of inner ring and outer ring is equal, all equals the distance between fore bearing and rear bearing.
The rotation of the utility model is floated mouth and can be processed longer stainless steel and harder material, and can process hexagonal material and various heterotypic material, ensures the quality of institute's converted products, improves the speed of converted products; Workpiece can be followed guide pin bushing and be rotated together, so just eliminates phase mutual friction between them thus the wear of work brought and guide pin bushing life-span short problem.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described further.
As depicted in figs. 1 and 2, numerically controlled lathe 1 is provided with successively main shaft 4, follow-rest 3 and knife rest 2, supporting plate 7 is also located on numerically controlled lathe 1.Knife rest 2 is positioned at the top of supporting plate 7, and follow-rest 3 is screwed and is connected on supporting plate 7.Follow-rest 3 is provided with and rotates floating mouth 5, and the hexagonal material work piece 6 of required processing passes main shaft 4 successively and rotates floating mouth 5 and finally contact with the lathe tool on knife rest 2.
As shown in Figure 3 and Figure 4, the floating mouth 5 of rotation is provided with in follow-rest seat 21 interstitial hole.
Rotate floating mouth 5 and be provided with floating mouth seat 22, floating mouth seat 22 is hollow form, and the guide pin bushing accompanying workpiece is just contained in floating mouth seat 22.Floating mouth seat 22 is also arranged with fore bearing 25 and rear bearing 28 liang of group bearings, is also provided with inner ring 26 between fore bearing 25 and rear bearing 28 and they separate by outer ring 27.Inner ring 26 to be set on floating mouth seat 22 and with floating mouth seat 22 interference fit, outer ring 27 be located at inner ring 26 periphery and with the hole wall interference fit of follow-rest seat 21 interstitial hole.The length of inner ring 26 and outer ring 27 is equal, all equals the length between fore bearing 25 and rear bearing 28.Like this, the stability of whole floating mouth is better, and floating mouth runs more smooth.
Rotate floating mouth 5 to be also provided with in gland 23 and rear pressing cover 31 before circular, they are equipped with screw hole, are screwed on follow-rest seat 21 and form a fixed connection with follow-rest seat 21.Also be provided with in circular Front oil seal 24 and Rear oil seal 29 at fore bearing 25 and the respective outside of rear bearing 28, Front oil seal 24 to be set on floating mouth seat 22 and to be positioned at front gland 23, and the external diameter of Front oil seal 24 is identical with the internal diameter of front gland 23.
Rotate floating mouth 5 and be also provided with nut 30, nut 30 is provided with internal thread (not shown in Fig. 3), and the rear end of floating mouth seat 22 is provided with external screw thread, and the internal thread of nut 30 and the external screw thread of floating mouth seat 22 cooperatively interact.Rear oil seal 29 is located at the periphery of nut 30, and the external diameter of Rear oil seal 29 is identical with the internal diameter of rear pressing cover 31, and front gland 23 is identical with rear pressing cover 31 specification.
When assembling, first inner ring 26 and outer ring 27 being put into the interstitial hole of follow-rest seat 21, fore bearing 25 and rear bearing 28 are loaded from both sides respectively; Then gland 23 and rear pressing cover 31 before installing, they fix by tighten the screws; Finally be loaded on Front oil seal 24 and Rear oil seal 29 from both sides, floating mouth seat 22 be pressed onto fore bearing 25 and rear bearing 28 li, tightening nuts 30.In the utility model, bearing can use two described above, also can use more than one or 2.
Below the course of work of the present utility model is illustrated.
After rotation floating mouth 5 assemble, according to the corresponding guide pin bushing of the Material selec-tion of required processing work, load and float in mouth seat 22, then in guide pin bushing, load workpiece, carry out debugging rear rotation and float mouth 5 and will rotate together with main shaft 4, carry out the processing of workpiece.
