Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of retainer ring processing setting, specifically relates to a spiral retainer ring processing and manufacturing equipment. BACKGROUND

[0002] The multi-layer spiral retainer ring is used for limiting the axial movement of the parts on the shaft. The manufacturing process of the existing multi-layer spiral retainer ring is as follows: according to the size requirements of the multi-layer spiral retainer ring, the annular blank is cut from the selected raw material, for the high-elasticity spiral retainer ring, the alloy plate material can also be used as the raw material through the wire cutting to process the spiral annular blank; then the annular blank is sleeved on the mold base, and the mold lower pressing piece is used for pressing, so that the spiral shape is formed, and the size accuracy and shape accuracy of the blank need to be ensured in this process. The forming process is not efficient, therefore, the researchers want to directly prepare the spiral retainer ring based on the rolling process, but the problem of how to control the forming diameter of the spiral retainer ring cannot be solved, so the method for preparing the spiral retainer ring based on the rolling process has not been fully applied. SUMMARY

[0003] Therefore, the utility model provides a spiral retainer ring processing and manufacturing equipment, and two groups of movable driving roller and a group of driven roller are arranged at the rolling end. The retainer ring adjusting part is arranged at the rolling end to control the forming diameter of the retainer ring, the spiral retainer ring with various materials and various diameters can be efficiently formed and processed, and the spiral retainer ring processing and manufacturing equipment has a very strong use prospect.

[0004] The technical scheme of the utility model is as follows:

[0005] A spiral retainer ring processing and manufacturing equipment is suitable for processing and forming the spiral retainer ring for aviation from the steel strip blank, and comprises the following:

[0006] The first driving roller is provided with a rolling groove on the outer ring.

[0007] The second driving roller is axially parallel to the first driving roller, is provided with a rolling groove on the outer ring, and is provided with a rolling power.

[0008] The driven roller is axially parallel to the first driving roller and is provided with a rolling groove on the outer ring.

[0009] The retainer ring adjusting part is provided with an adjusting roller, the side, away from the driven roller, of the adjusting roller is a steel strip channel, the adjusting roller and the steel strip channel are axially parallel to the first driving roller, and the distance between the adjusting roller, the steel strip channel and the driven roller is adjustable.

[0010] The moving direction of the first driving roller and the second driving roller is towards or away from the driven roller; the steel belt passes through the rolling groove on the first driving roller, reaches the rolling groove of the driven roller, then reaches the rolling groove of the second driving roller, and then contacts the adjusting roller and passes through the steel belt passage; the distance between the steel belt passage and the driven roller is controlled by the adjusting part of the check ring based on adjusting the forming diameter of the screw check ring.

[0011] Further, the rolling groove structures on the first driving roller, the second driving roller and the driven roller are the same and the middle lines are in the same plane.

[0012] Further, the adjusting roller is provided with an adjusting groove; the middle line of the adjusting groove is in the same plane as the middle line of the driven roller.

[0013] Further, the moving direction of the adjusting roller is towards or away from the middle axis of the driven roller.

[0014] Further, the adjusting part of the check ring further comprises a base, a sleeve and a lead screw; one end of the lead screw is rotatably installed on the base, the other end is sleeved and threadedly connected with the internal thread of the sleeve; the adjusting roller is rotatably installed at the end of the sleeve away from the lead screw.

[0015] Further, the base is fixedly provided with a pointer, and the sleeve is provided with a scale; the pointer and the scale display the distance between the adjusting roller and the driven roller.

[0016] Further, the end of the lead screw away from the sleeve is provided with a screw handle; the screw handle facilitates the rotation of the lead screw.

[0017] The distance between the two groups of driving rollers and the driven roller can preliminarily control the rolling angle of the steel belt, but the forming angle cannot be accurately controlled when the rear end is not limited, therefore, the application also reversely limits the forming angle of the steel belt on the three rollers based on the adjusting roller as a control point, so that the forming size of the screw check ring can be accurately controlled.

[0018] The pointer and the scale are arranged, the control size of the check ring processing can be recorded, and the steel belt material or the check ring diameter can be quickly restored after being changed. BRIEF DESCRIPTION OF DRAWINGS

[0032] A retainer adjusting part 4 is provided with an adjusting roller 41, and the side of the adjusting roller 41 away from the driven roller is a steel strip passage 42, which is axially parallel to the first driving roller 1, and the distance between the adjusting roller 41 and the steel strip passage 42 and the driven roller is adjustable;

[0033] The moving direction of the first driving roller 1 and the second driving roller 2 is towards or away from the driven roller 3; the steel belt passes through the roller groove on the first driving roller 1, reaches the roller groove of the driven roller 3, then reaches the roller groove of the second driving roller 2, and then contacts the adjusting roller 41 and passes through the steel belt passage 42; the distance between the steel belt passage 42 and the driven roller 3 is controlled by the adjusting part 4 based on the adjusting of the spiral retainer.

[0034] In the embodiment, the roller groove structures of the first driving roller 1, the second driving roller 2 and the driven roller 3 are the same and the middle lines are in the same plane.

[0035] In the embodiment, the adjusting roller 41 is provided with an adjusting groove; the middle line of the adjusting groove is in the same plane with the middle line of the driven roller 3.

[0040] Since the forming angle cannot be accurately controlled when the rear end of the roller is not limited, the forming effect is poor, especially for large size spiral retainers (such as Figure 1 The use process of the embodiment is as follows:

[0041] The steel belt passes through the first driving roller 1, the second driving roller 2, the driven roller 3 and the steel belt passage 42 at the same time;

[0042] Then, based on experience, the distance between the first driving roller 1 and the second driving roller 2 and the driven roller 3 is preliminarily adjusted respectively, and the forming angle of the steel belt on the three rollers is reversely limited based on the adjusting roller 41 as the control point;

[0043] The steel belt is initially rolled and the forming difference is measured, then the first driving roller 1, the second driving roller 2 and the adjusting roller 41 (mainly the adjusting roller 41) are accurately adjusted based on the forming difference until the forming size of the formed spiral retainer meets the requirements (such as Figure 2 shown);

[0044] The first driving roller 1, the second driving roller 2 and the adjusting roller 41 are kept, and the mass production of the spiral retainer is started.

[0045] At this time, the specific position of the adjusting roller 41 can be recorded based on the scale 47 and the pointer 46, and the material and the forming size of the spiral retainer are combined to provide experience for technicians when processing spiral retainers of different sizes or different materials, so as to quickly deploy or quickly restore.
