Description
Technical Field
The invention belongs to a machine tool accessory, and particularly relates to a centre frame of a unblocked long roller jaw lathe.
Background
The lathe is the most common important equipment used in machining, when a slender shaft with a larger length and diameter is machined on the lathe, the slender shaft is poor in rigidity and easy to deform, the machining precision is difficult to control, the slender shaft is a difficult point and a key point in lathe machining, the rigidity of the slender shaft is generally required to be enhanced by a lathe center frame, and the deformation of the slender shaft is reduced, so that the quality of the structure and the performance of the lathe center frame is very important. Most of the existing lathe center frames comprise an upper part and a lower part, the frame body is fastened by screws to form a closed frame, and three clamping jaws are arranged at intervals of 120 degrees on the basis of the clamping jaws right above the center of a lathe to position a workpiece. When a workpiece is turned, the workpiece is fed to a lathe center frame, and the workpiece needs to be stopped and processed in sections due to the blocking of the lathe center frame. After the right side of the lathe center frame is machined, the lathe center frame is moved to a right machined area close to the original position of the lathe center frame, and after the lathe center frame is repositioned, the left unprocessed shaft section is machined, so that the production efficiency is low. There are also open lathe centers that have the disadvantage of unbalanced force application to the workpiece by the three jaws.

The invention provides a unblocked type long roller jaw lathe center frame which can be used for uniformly applying force to a workpiece, enables the turning to be continuously carried out and has higher production efficiency, and aims to solve the problems that the turning cannot be continuously carried out due to most of the existing lathe center frames, and the three jaws cannot uniformly apply force to the workpiece due to a part of open type lathe center frames.
The technical scheme adopted by the invention is as follows: the center frame of the open-type long roller jaw lathe comprises a center frame body and a long roller jaw mechanism; the center frame body is an open frame body which is rigid enough and is open towards the lathe tool rest direction, and is connected with the lathe guide rail, and the pressing plate screw and the pressing plate nut tightly press the center frame body on the lathe guide rail through the pressing plate. Three long roller jaw mechanisms are uniformly distributed on the center frame body at intervals, and one long roller jaw mechanism is arranged right below the center line of the lathe. In the long roller jaw mechanism, a long roller jaw shaft is connected with a long roller jaw frame through a long roller jaw bearing, the long roller jaw frame is connected with a long roller jaw frame body, the long roller jaw is connected with the long roller jaw shaft, and the long roller jaw frame body is connected with an adjusting block and is in movable fit connection with the long roller jaw frame body.

And the adjusting screw is rotated, and the adjusting block drives the long roller jaw frame body, the long roller jaw frame, the long roller jaw bearing, the long roller jaw shaft and the long roller jaw to move along the axis direction of the adjusting screw, so that the position of the long roller jaw is adjusted according to the diameter of the workpiece. After the position of the long roller clamping jaw is adjusted, the clamping jaw locking screw is screwed, the position of the long roller clamping jaw is fixed, and then the workpiece can be machined. The pressure plate screw and the pressure plate nut are clamped through the pressure plate.
Preferably, the central frame body is an open frame body which is open in the direction of the lathe tool holder and ensures sufficient rigidity.
Preferably, the three long roller jaw mechanisms are uniformly distributed on the central frame body at intervals, and one long roller jaw mechanism is arranged right below the center line of the lathe.
The invention has the beneficial effects that: the center frame body is an open type frame body which is rigid enough and is open towards the direction of the lathe tool rest, three long roller jaw mechanisms are uniformly distributed on the center frame body at intervals of 120 degrees, one long roller jaw mechanism is arranged right below the center line of the lathe, and balanced stress of the slender shaft type machined part can be guaranteed. The turning device can continuously turn at the center frame when turning the slender shaft type workpiece, unlike the common center frame, the turning device needs to stop at the center frame due to the blocking of the center frame when turning the slender shaft type workpiece, and after one side of the center frame is machined, the center frame is moved, and the other side which is not machined is turned. The turning of the slender shaft type workpiece has higher working efficiency. The long roller jaw mechanism is adopted, the support length of the slender shaft type workpiece is lengthened, the rigidity of the slender shaft type workpiece is greatly increased, and the turning quality of the slender shaft type workpiece is improved.
