Description

Technical Field

[0001] The utility model belongs to the technical field of shaft workpieces, and specifically relates to an auxiliary supporting mechanism for machining shaft workpieces. Background Art

[0002] Large shaft workpieces usually refer to shaft-shaped parts with larger diameter and longer length, which may be used in heavy machinery, ships, power generation equipment and other fields. The processing of large shaft workpieces usually involves turning, milling, drilling and other processing operations on the shaft-shaped workpieces to make them have specific shapes, sizes and surface accuracy.

[0003] In the prior art, a chuck and a center are usually used to directly fix the two ends of a large shaft workpiece. However, due to the relatively large overall mass of the large shaft workpiece, it may be difficult to further support the bearings at both ends during the fixing process, resulting in the inability to reduce the load of the chuck and the center, which may cause instability during the processing. In addition, due to the different heights of some processing equipment, it may be inconvenient to adjust the height of the fixed large shaft workpiece during the processing, thereby making it inconvenient to adjust the large shaft workpiece to a height consistent with the processing equipment;

The bottom outer circumference of the clamping rod 24 is equal to the inner circumference of the positioning hole 22. After the positioning hole 22 is adjusted to a suitable position, the clamping rod 24 first penetrates the circular hole 23 and then is connected to the balance board 1 through the positioning hole 22, thereby limiting the position of the bottom plate 21 after adjustment.

[0037] Reference Figure 2 An ear plate 25 is fixedly connected to the bottom plate 21, and a threaded rod 26 is rotatably connected inside the ear plate 25. A hexagonal block 27 is fixedly connected to one end of the threaded rod 26. The hexagonal block 27 is located at the center of one end of the threaded rod 26. A sleeve block 28 is threadedly connected to the outer wall of the threaded rod 26. An adjustment block 29 is fixedly connected to the top of the sleeve block 28.

The annular pad 44 is mainly composed of sponge material. The annular pad 44 is fixedly connected to the guide block 6. The outer wall of the guide rod 5 fits with the inner wall of the annular pad 44. After the lubricating oil transmitted by the transmission pipe 43 penetrates the annular pad 44, the inner ring of the annular pad 44 contacts with the outer wall of the guide rod 5 during the movement of the positioning hole 22, thereby maintaining the guide rod 5.

[0040] Reference Figure 5 The top of the oil tank 41 is fixedly connected to an oil replenishing pipe 45, and the top of the oil replenishing pipe 45 is threadedly connected to a closing cap 46. The inner side wall of the closing cap 46 is matched with the outer side of the top of the oil replenishing pipe 45. The closing cap 46 and the oil replenishing pipe 45 facilitate adding lubricant to the interior of the oil tank 41.

[0041] Working principle: First, the distance between the two U-shaped frames 32 is adjusted, and the inner wall of the guide block 6 moves horizontally along with the outer wall of the guide rod 5, so that the U-shaped frame 32 moves horizontally and adjusts. After the distance between the two U-shaped frames 32 is adjusted, the clamping rod 24 first penetrates the circular hole 23 and then connects to the balance plate 1 through the positioning hole 22, thereby limiting the position of the U-shaped frame 32 after adjustment. At the same time, the lubricant can be added to the inside of the oil tank 41 through the use of the oil replenishment pipe 45 and the closing cover 46. The sponge block 42 allows the lubricant inside the oil tank 41 to slowly flow into the inside of the transmission pipe 43. The transmission pipe 43 transmits the lubricant, and the lubricant penetrates the annular pad 44. When the bottom plate 21 moves, the lubricant on the inner circle of the annular pad 44 is smeared on the guide rod 5, thereby maintaining the guide rod 5 and increasing the convenience of horizontal movement of the bottom plate 21.

[0042] The hexagonal block 27 drives the threaded rod 26 to rotate, and the ear plate 25 drives the adjustment block 29 to move, thereby adjusting the front and rear position of the steel plate 31, thereby facilitating the support of large shaft workpieces;

[0043] The bearings on the large shaft workpieces are moved to fit with the support seats 36 through the V-grooves 37. The two support seats 36 support the bearings at both ends of the shaft workpieces, reduce the load on the chuck and the center, and improve the processing effect. When the height of the large shaft workpiece needs to be adjusted after placement, the hydraulic rod 33 operates, the spring 312 is compressed and deformed, the sleeve 34 drives the square plate 35 to move upward, and the support seat 36 drives the large shaft workpiece to move upward after placement, thereby adjusting the large shaft workpiece to a suitable processing height.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
