Abstract
The utility model provides a floating center frame lathe, which comprises a base, a clamping mechanism and a movable tool rest, wherein the clamping mechanism and the movable tool rest are positioned on the base; the centering tailstock is connected with a tailstock screw rod, and the tailstock screw rod controls the qualitative tailstock to axially displace along the workpiece. According to the utility model, the workpiece is centered and clamped through the main shaft mechanism and the centering tail frame, the irregular part in the middle of the workpiece is clamped through the floating center frame, and finally the centering tail frame is removed to process the tail of the workpiece, so that the long workpiece with irregular middle shape can be processed, and the use is convenient.
Description
Technical Field
The utility model relates to the field of machining equipment, in particular to a floating center frame lathe.
Background
The lathe is a machine tool for turning a rotating workpiece with a turning tool. A lathe is the most important type of metal cutting machine, and is called a machine tool, which is the largest in number among lathes in a general machine factory. The lathe can also be used for corresponding machining by using a drill bit, a reamer, a tap, a die, a knurling tool and the like. Lathes are used for cutting various rotating surfaces of different sizes and shapes, as well as spiral surfaces.
When the existing lathe processes a longer workpiece, a clamping mechanism needs to be added in the middle of the workpiece, so that the stability of the whole processing process is ensured. The clamping mechanism generally adopts self-centering clamping, and if the roundness of the middle part of the workpiece is poor or the whole workpiece is a special-shaped piece, the workpiece cannot be clamped through the self-centering mechanism.
Disclosure of utility model
The utility model aims to solve the problems in the prior art, and provides a floating center frame lathe which is characterized in that a workpiece is centered and clamped through a main shaft mechanism and a centering tail frame, an irregular part in the middle of the workpiece is clamped through the floating center frame, and finally the centering tail frame is removed to process the tail of the workpiece, so that a long workpiece with irregular middle shape can be processed, and the lathe is convenient to use.
The utility model comprises a base, a clamping mechanism and a movable tool rest, wherein the clamping mechanism and the movable tool rest are positioned on the base, the clamping mechanism comprises a main shaft mechanism, a floating center frame and a centering tail frame which are positioned on the same axis, and the movable tool rest is positioned between the floating center frame and the centering tail frame; the centering tailstock is connected with a tailstock screw rod, and the tailstock screw rod controls the qualitative tailstock to axially displace along the workpiece.
Further improved, the movable tool rest is connected with an xyz triaxial displacement mechanism.
Further improved, the floating center frame is provided with movable chucks distributed along the radial direction, and after the workpiece is centered and fixed through the main shaft mechanism and the centering tail frame, the movable chucks movably clamp the middle section of the workpiece along the radial direction.
The utility model has the beneficial effects that: the workpiece is centered and clamped through the main shaft mechanism and the centering tail frame, the irregular part in the middle of the workpiece is clamped through the floating center frame, and finally the centering tail frame is removed to process the tail of the workpiece, so that the long workpiece with irregular middle shape can be processed, and the centering device is convenient to use.

Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model comprises a base 1, a clamping mechanism and a movable tool rest 2, wherein the clamping mechanism is positioned on the base and comprises a main shaft mechanism 3, a floating center frame 4 and a centering tail frame 5 which are positioned on the same axis; the centering tailstock is connected with a tailstock screw rod 6, and the tailstock screw rod controls the qualitative tailstock to axially displace along the workpiece.
Further improved, the movable tool rest is connected with an xyz triaxial displacement mechanism, and the displacement mechanism comprises an x-axis screw rod 7, a y-axis screw rod 8, a z-axis screw rod 9 and a small supporting plate 10.
Further improved, the floating center frame is provided with movable chucks distributed along the radial direction, and after the workpiece is centered and fixed through the main shaft mechanism and the centering tail frame, the movable chucks movably clamp the middle section of the workpiece along the radial direction.
The working method of the utility model is as follows: the workpiece is centered and clamped through the main shaft mechanism and the centering tail frame, the irregular part in the middle of the workpiece is clamped through the floating center frame (non-self-centering), and finally the centering tail frame is removed to process the tail of the workpiece, so that the workpiece centering device is convenient to use.
In this specification, each embodiment is described in a progressive manner, and identical and similar parts of each embodiment are all referred to each other, and each embodiment mainly describes differences from other embodiments. In particular, for the equipment examples, what has been described above is merely a preferred embodiment of the utility model, which, since it is substantially similar to the method examples, is described relatively simply, as relevant to the description of the method examples. The foregoing is merely illustrative of specific embodiments of the present utility model, and the scope of the utility model is not limited thereto, since modifications and substitutions will be readily made by those skilled in the art without departing from the spirit of the utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
