A lathe is a machine tool for turning a rotating workpiece mainly with a lathe tool. In a common lathe, a tool rest for placing a tool is fixed on a carriage, and machining of a workpiece is achieved by sliding the carriage, wherein a lathe backer is used for limiting the stroke of the carriage so as to control the feed amount of the tool. The existing lathe backer is generally plugged in from the tail of the equipment by a cylindrical long rod backer, penetrates through a spindle box of the equipment, fastens a positioning backer at the tail of the equipment, and suspends the front end in a hole of a chuck. In order to improve the wear resistance of the lathe backer and facilitate the discharge of the waste chips during lathe machining, the existing lathe backer is often provided with a stopper, and the purpose is mainly to improve the wear resistance of the lathe backer and discharge the waste chips through a chip discharge cavity inside the stopper. However, the existing design of the back stop for lathe has the defects that scraps discharged during processing are easy to rebound to damage a workpiece or a blade, and the back stop has the effect of preventing the back stop of the lathe from being worn, but the back stop is worn, so that the back stop needs to be replaced after long-term use, and the use cost is high. In addition, when the chamfer or the sealing groove is turned inside, chips are easy to enter the inside of the workpiece, so that the inner diameter of the workpiece is scratched.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses a retainer assembly with a gasket [201921002246.7] for a hydraulic lathe backer, which includes a retainer body, a mounting seat, a positioning cylinder and a retaining cylinder, wherein a plurality of mounting holes are provided on the outer circumferential side of the mounting seat, a plurality of oil passages sequentially penetrating through the mounting seat, the positioning cylinder and the retaining cylinder are provided in the retainer body, at least one annular gasket is sleeved on the outer circumferential side of the positioning cylinder, a plurality of matching holes corresponding to the mounting holes one by one and a plurality of oil holes communicated with the oil passages are provided on the outer circumferential side of the gasket, the gasket near one end of the mounting seat in the gasket abuts against the mounting seat, and a circumferential positioning structure is provided between the gasket and the mounting seat.

The scheme solves the problem that the scraps are easy to rebound to damage the workpiece and the cutter to a certain extent, but the scheme still has a plurality of defects, such as the problem that the scraps are easy to enter the inside of the workpiece to damage the inner diameter of the workpiece when an inner chamfer or a sealing groove is turned.
