Technical Field

The invention relates to the technical field of machining, in particular to a metal product machining, positioning and turning device.

Background

Metal products are difficult to machine in a conventional manner due to their high hardness and strength, and are therefore generally machined by turning with a lathe. The turning processing is to carry out cutting processing on a metal workpiece by utilizing the rotation of the workpiece relative to a cutter on a lathe, has wide processing range and various types, can process most of workpieces with rotary surfaces by a turning method, is easier to operate compared with the prior manual processing, greatly promotes the production of mechanical processing, and improves the quality of processed products.

However, the existing positioning turning device of the automatic lathe has the following defects:

under the action of dead weight and centrifugal force during rotation when processing a slender workpiece, the workpiece can vibrate and bend, the used follow rest is heavy, the advancing resistance is large, the installation is complex, and the friction generated by the contact end of the follow rest and the workpiece is large, so that the advance of the follow rest is not facilitated.

Disclosure of Invention

In order to overcome the technical problem in the prior art, the invention provides a metal product machining, positioning and turning device, and aims to solve the problem of unsmooth machining caused by vibration and complex structure in the prior art.

In order to achieve the above object, the embodiments of the present invention provide the following technical solutions:

the utility model provides a metal product processing location turning device, includes the lathe bed, the guide rail, the knife rest, the follower, and install the carriage apron on a guide rail, be provided with the track of follower motion on the guide rail, the follower is provided with base and support section, the follower is provided with the support screw.

Further, the track on the guide rail extends transversely across the entire guide surface.

Further, pulleys are arranged on two support legs of the follow rest, the upper part of the follow rest is of an arc structure, a bearing is arranged at the top end of the supporting screw rod,

furthermore, the bearing is connected with the supporting screw rod through a pin shaft, and the diameter of the bearing is the same as that of the supporting screw rod.

Further, the base and the support portion of the steady rest are detachable.

The invention has the beneficial effects that:

when the device is used for turning the slender workpiece, the follow rest moves forwards in a rolling mode on the rail, the advancing assistance of the follow rest and the rail is reduced, and the follow rest is in contact with the workpiece through the bearing, so that the friction force between the follow rest and the workpiece is greatly reduced, the turning engineering of the slender workpiece is effectively guaranteed, the mounting is convenient, and the operation is simple.
