A type of fixing fixture for stamping ribs

Abstract

This utility model discloses a fixing fixture for stamping shaft ribs, relating to the field of shaft processing technology. It includes a left buffer support and a right buffer support. A support side plate is fixedly installed on the left buffer support, and a 360-degree rotating cylinder is mounted on the support side plate. A pneumatic chuck is mounted on the turntable of the 360-degree rotating cylinder. With this fixing fixture, one end of the shaft to be processed is placed in the pneumatic chuck and clamped, while the other end is supported on the lower roller. At this time, the lifting cylinder drives the guide rod and the upper support to descend, causing the upper roller to press and fix the shaft to be processed. After fixing, ribs can be stamped.

This effectively improves production efficiency, reduces the labor intensity of workers, and ensures that the spacing of the four ribs is consistent, which also facilitates the assembly of subsequent parts.

Description

Technical Field

[0001] This utility model relates to the field of shaft processing technology, specifically a fixing fixture for stamping shaft ribs. Background Technology

[0002] Currently, punching ribs on motor shafts is mainly done using a stamping machine. The motor shaft is placed below the stamping machine and fixed, and stamping tools are set on the slide of the stamping machine. Then, the stamping machine directly punches the motor shaft.

[0003] Because four ribs need to be set on the motor shaft, after the first pressing is completed, the shaft is manually rotated 90 degrees for the second pressing. It takes four consecutive pressings to complete the pressing of the ribs on the motor shaft. It is difficult for a person to control the rotation angle, and there is also a certain error between each rotation, which affects the machining accuracy of the shaft. Utility Model Content

[0004] This utility model provides a fixing fixture for stamping ribs to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing fixture for stamping shaft ribs, comprising a left buffer support and a right buffer support. A support side plate is fixedly installed on the left buffer support, and a 360-degree rotating cylinder is installed on the support side plate. A pneumatic chuck is installed on the turntable of the 360-degree rotating cylinder, and a shaft to be processed is clamped and fixed on the pneumatic chuck. A lower bracket is installed on the right buffer support, and a lower roller is installed at the top of the lower bracket via a bearing. Lifting cylinders are installed on the front and rear sides of the lower bracket, and a guide rod is connected to the output end of the lifting cylinder. An upper bracket is fixedly installed at the top of the guide rod, and an upper roller is installed at the bottom of the upper bracket via a bearing.

[0006] Furthermore, both the left and right buffer supports include a base plate, a connecting rod, a spring, and a top plate. The connecting rod is embedded around the base plate, the spring is fitted onto the connecting rod, and the top plate is movably fitted onto the connecting rod.

[0007] Furthermore, a limit nut is threaded to the top of the connecting rod, and the limit nut is located above the top plate.

[0008] Furthermore, the lower roller is located at both ends of the lower bracket, and the lower roller is supported on the lower part of the shaft to be processed.

[0009] Furthermore, guide sleeves are fitted at both ends of the lower bracket, and the guide rod is movably fitted into the guide sleeves.

[0010] Furthermore, the upper roller is located at both ends of the upper bracket, and the upper roller presses against the upper part of the shaft to be processed.

[0011] Compared with the prior art, the present invention provides a fixing fixture for stamping rib shafts, which has the following advantages:

[0012] The fixed fixture for stamping the shaft ribs uses a pneumatic chuck to hold one end of the shaft to be processed, while the other end is supported on the lower roller. At this time, the lifting cylinder drives the guide rod and the upper bracket to descend, so that the upper roller presses and fixes the shaft to be processed. After fixing, the ribs can be stamped. Each time a rib is stamped, the 360-degree rotating cylinder drives the shaft to be processed to rotate 90 degrees. After four consecutive rotations, four ribs can be stamped on the shaft at one time, which can effectively improve production efficiency, reduce the labor intensity of workers, and ensure that the spacing of the four ribs is consistent, which also makes the assembly of subsequent parts more convenient.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model discloses a fixing fixture for stamping shaft ribs, including a left buffer support 1 and a right buffer support 2. A support side plate 3 is fixedly installed on the left buffer support 1, and a 360-degree rotating cylinder 4 is installed on the support side plate 3. A pneumatic chuck 5 is installed on the turntable of the 360-degree rotating cylinder 4, and a shaft 6 to be processed is clamped and fixed on the pneumatic chuck 5. A lower bracket 7 is installed on the right buffer support 2, and a lower roller 8 is installed on the top of the lower bracket 7 through a bearing. Lifting cylinders 9 are installed on the front and rear sides of the lower bracket 7, and the output end of the lifting cylinder 9 is connected to a guide rod 10. One end of the shaft 6 to be processed is placed into the pneumatic chuck 5 for clamping, and the other end... One end is placed on the lower roller 8. At this time, the lifting cylinder 9 drives the guide rod 10 and the upper bracket 11 to descend, so that the upper roller 12 presses on the shaft to be processed 6 for fixation. After fixation, the ribs can be punched. Each time a rib is punched, the 360-degree rotating cylinder 4 drives the shaft to be processed 6 to rotate 90 degrees. After four consecutive rotations, four ribs can be punched on the shaft at one time, which can effectively improve production efficiency and reduce the labor intensity of workers. Moreover, the spacing of the four ribs can be guaranteed to be consistent, which can also make the assembly of subsequent parts more convenient. The upper bracket 11 is fixedly installed at the top of the guide rod 10, and the upper roller 12 is installed at the bottom of the upper bracket 11 through the bearing.

[0020] Specifically, both the left buffer support 1 and the right buffer support 2 include a base plate 13, a connecting rod 14, a spring 15, and a top plate 16. The connecting rod 14 is embedded around the base plate 13, the spring 15 is fitted onto the connecting rod 14, and the top plate 16 is movably fitted onto the connecting rod 14.

[0021] In this embodiment, the left buffer support 1 and the right buffer support 2 allow the structure to undergo longitudinal expansion and contraction and small displacement, so as to facilitate the operation of the stamping machine.

[0022] Specifically, the top end of the connecting rod 14 is threaded with a limiting nut 17, and the limiting nut 17 is located above the top plate 16.

[0023] In this embodiment, the limiting nut 17 is used to limit the rebound stroke of the spring 15.

[0024] Specifically, the lower roller 8 is located at both ends of the lower bracket 7, and the lower roller 8 is supported on the lower part of the shaft 6 to be processed.

[0025] In this embodiment, the other end of the shaft 6 to be processed is placed on the lower roller 8 for support.

[0026] Specifically, guide sleeves 18 are fitted at both ends of the lower bracket 7, and the guide rod 10 is movably fitted in the guide sleeves 18.

[0027] In this embodiment, the main functions of the guide sleeve 18 and the guide rod 10 are to guide and position, ensuring the accuracy and stability of the upper support 11 during movement.

[0028] Specifically, the upper roller 12 is located at both ends of the upper bracket 11, and the upper roller 12 presses against the upper part of the shaft 6 to be processed.

[0029] In this embodiment, the lifting cylinder 9 drives the guide rod 10 and the upper bracket 11 to descend, so that the upper roller 12 presses against the shaft to be processed 6 for fixation.

[0030] In use, the lower die of the punching mold is fixed to the table of the stamping machine, and the upper die (punching tool) is fixed to the slide of the stamping machine. The fixing fixture is set on both sides of the lower die. One end of the shaft to be processed 6 is placed in the pneumatic chuck 5 for clamping, and the other end is supported on the lower roller 8. At this time, the lifting cylinder 9 drives the guide rod 10 and the upper bracket 11 to descend, so that the upper roller 12 presses and fixes the shaft to be processed 6. At this time, the shaft to be processed 6 is suspended on the lower die of the punching mold. Then the stamping machine drives the upper die to punch downward to form the rib. During the punching process, the left buffer support 1 and the right buffer support 2 are compressed downward, so that the shaft to be processed 6 comes into contact with the upper die. The lower and upper dies of the punching die continuously press downwards until ribs are formed on the shaft 6 to be processed. Then the upper die rises and resets, and the left buffer support 1 and right buffer support 2 rise and reset. Then the 360-degree rotating cylinder 4 (the working principle is to rotate 90 degrees once and then rotate 90 degrees four times in a row to achieve cyclic rotation) drives the shaft 6 to rotate 90 degrees. This is repeated four times in a row, which can punch four ribs on the shaft at one time. This can effectively improve production efficiency, reduce the labor intensity of workers, and ensure that the spacing of the four ribs is consistent, which can also make the assembly of subsequent parts more convenient.

[0031] In summary, the fixed fixture for stamping the shaft ribs uses a pneumatic chuck 5 to hold one end of the shaft 6 to be processed, while the other end is supported on the lower roller 8. At this time, the lifting cylinder 9 drives the guide rod 10 and the upper bracket 11 to descend, so that the upper roller 12 presses against the shaft 6 to be processed for fixation. After fixation, the ribs can be stamped. Each time a rib is stamped, the 360-degree rotating cylinder 4 drives the shaft 6 to be processed to rotate 90 degrees. After four consecutive rotations, four ribs can be stamped on the shaft at one time, which can effectively improve production efficiency, reduce the labor intensity of workers, and ensure that the spacing of the four ribs is consistent, which also makes the assembly of subsequent parts more convenient.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
