Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of turbine rod processing frock, specifically a turbine rod processing frock. BACKGROUND

[0002] In the processing of turbine rod, centering is one of the key links. The traditional method often has the problems of centering difficulty and inaccurate positioning, which leads to low processing efficiency and difficult to guarantee the processing quality. When each workpiece is processed, a tedious positioning step is needed, which seriously affects the work efficiency. Therefore, it is of great significance to develop a processing frock that can quickly and accurately realize the centering positioning of turbine rod. SUMMARY

[0003] To solve the above problems, that is, to solve the problems raised in the above background technology, the utility model provides a turbine rod processing frock, which comprises a center sleeve that can be detachably installed on the main shaft seat of a lathe, a center hole is formed on one side of the center sleeve to allow the center of the lathe to pass through, and a positioning end cover is detachably installed on one side of the center sleeve.

[0004] The center hole and the positioning hole are on the same axis as the center of the lathe.

[0005] The utility model further provides that an installation hole is formed on the outer wall of the center sleeve.

[0006] The utility model further provides that the center sleeve is installed on the main shaft seat of the lathe through positioning bolts.

[0007] The utility model further provides that the positioning end cover is installed on the center sleeve through positioning bolts.

[0008] The turbine rod processing quick centering positioning frock provided by the utility model can quickly and accurately realize the centering positioning of turbine rod. When processing the same batch of workpieces, the centering positioning step can be completed by inserting the turbine blade of the workpiece into the positioning hole each time the workpiece is fixed, which greatly improves the processing efficiency and accuracy. By replacing the positioning end cover with a matching positioning hole, the turbine processing requirements of different sizes can be met, and the frock has strong versatility and flexibility. The frock structure is simple and easy to operate, which reduces the labor intensity of workers and improves the safety and stability of the processing process. The overall cost of the scheme is low, and it is different from special work. It does not need to be specially made according to each batch of workpieces, has certain universality, and can be used for processing most turbine workpieces. BRIEF DESCRIPTION OF DRAWINGS

[0014] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0015] The utility model provides a kind of turbine rod processing frock, according to the outer diameter of the turbine blade place processing selects matching positioning end cap 2, the inner diameter of positioning port 5 is consistent with the outer diameter of turbine blade place, positioning end cap 2 is installed on the one end of top sleeve 1 away from top port 4 by positioning bolt, then the top port 4 of top sleeve 1 is sleeved on the top outer wall, and the side of top port 4 is attached to main shaft base, positioning bolt is placed in screw hole inside top sleeve 1 by mounting port 3 on the outer wall of top sleeve 2 to install, to complete the installation work of processing frock.

[0016] The setting of mounting port 3 is to install positioning end cap 2 first, then install top sleeve 1 on lathe main shaft base, to avoid installing top sleeve 1 first, and then manually positioning end cap 2 to complete positioning during installation.

[0017] During processing, turbine is placed in positioning port 5, the outer wall of turbine is attached to the inner wall of positioning port 5, at this time turbine can only move horizontally in positioning port 5, the end of turbine rod inside top sleeve 1 is in contact with top, positioning is completed, then staff controls the top of the other side to move to the other end of turbine rod to complete the fixation of turbine rod.

[0018] When other size turbine is processed, only positioning end cap 2 is removed, and positioning end cap 2 with matching positioning port 5 is replaced.
