AI Technical Summary
In existing piston ring trimming machines, metal powder tends to accumulate on the pressure plate during use, making cleaning difficult. Furthermore, relative rotation between the pressure plate and the shaft can easily occur, affecting the trimming quality. The connection method is also inconvenient for operation.
A piston ring trimming machine pressure plate was designed. The pressure plate body is larger at one end and smaller at the other. It has a beveled surface and a hollow structure. Combined with positioning grooves and screw holes, it ensures the fixation of the pressure plate to the shaft, and the beveled surface facilitates the outflow of metal powder.
It improved the quality of the finishing process, reduced the labor intensity of workers, increased production efficiency, ensured that the pressure plate and shaft were fixed and did not rotate, and simplified the operation process.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of the key device of the mouth repairing machine in the mouth repairing procedure of the automobile piston ring, and particularly relates to a piston ring mouth repairing machine pressing plate.
BACKGROUND TECHNIQUE
[0002] The piston ring is a core component in the automobile engine, and is high-speed worked in a harsh environment of high temperature, high pressure, alternating load and poor lubrication condition. In addition to being matched with the main engine of the automobile, the replacement frequency of the piston ring in use on the market is also high. Therefore, the piston ring market demand is large. In the piston ring production procedure, a production procedure is a mouth repairing procedure. The pressing plate is needed in the piston ring mouth repairing procedure. Figure 6 The upper surface of the pressing plate block 11 is a horizontal surface. Metal powder carried by the mouth repairing liquid of the mouth repairing machine is easily accumulated on the surface, and is not easy to be discharged. In particular, the worker is difficult to clean during the shift change, and the labor intensity of the worker is increased. On the other hand, the connection between the upper surface of the pressing plate block 11 and the original shaft 12 is a clear surface structure. Therefore, the relative rotation between the original shaft 12 and the pressing plate block 11 occurs. Once the rotation occurs, the opening orientation of the pressing plate block 11 changes, and the mouth repairing quality is affected. In addition, the old connection mode adopts the internal hexagonal bolt 10 connection, and the connection direction of the internal hexagonal bolt 10 is from bottom to top. When the internal hexagonal bolt 10 is tightened, the hand must be tightly held, otherwise the opening position of the pressing plate block 11 is not correct.
[0003] In order to overcome the above technical problems, the applicant discloses a piston ring mouth repairing machine pressing plate.
