Adjustable core frame assembly

Abstract

The invention discloses an adjustable core frame assembly. The adjustable core frame assembly comprises a split shaft, a bearing assembly, an upper fixed seat body and a lower fixed seat body, whereinthe upper fixed seat body and the lower fixed seat body can be fixed to a half-moon-shaped fixed seat of a machine body of a centrifugal machine. The bearing assembly is located between the upper fixed seat body and the lower fixed seat body, the two ends of the bearing assembly partially extend to the interior of the fixed seat, the split shaft sequentially penetrates through the upper fixed seat body, the bearing assembly and the lower fixed seat body from top to bottom, the split shaft comprises an adjusting threaded shaft located on the upper portion and a hollow shaft located on the lower portion, an external thread in the top end of the adjusting threaded shaft is matched and in threaded connection with an internal threaded hole in the top end of the upper fixed seat body, the top end of the hollow shaft is arranged on the outer portion of the bottom end of the adjusting threaded shaft in a sleeving mode, and the bottom end of the hollow shaft is fixedly connected to the lower fixed seat body; and the central axes of the adjusting threaded shaft, the upper fixed seat body, the hollow shaft and the lower fixed seat body are coaxially arranged, a swing arm is formed through extending on the outer wall of the bearing assembly, and the swing arm can rotate by taking the central axis as the axis. According to the adjustable core frame assembly, the structure is simple, usingis convenient, the equipment failure rate is greatly decreased, the production efficiency is improved, and the equipment maintenance cost is reduced.

Description

technical field [0001] The invention relates to an adjustable core frame assembly. Background technique [0002] At present, there is no adjustment function for the mechanism of the small centrifuge used to core the centrifugal pouring machine. When the position of the core frame changes due to wear or external force, the core frame arm cannot be adjusted, resulting in the centrifuge being unable to work. And the maintenance is very cumbersome. It is necessary to cut the whole core frame and readjust it before welding. The adjustment process is time-consuming and laborious, and the adjustment quality is poor, which will cause great damage to the equipment and affect the production efficiency and quality of the cast pipe. This part is a heavily polluted area, and wastes such as molten iron, dust, water, and sand cores flow very heavily, and how to solve the sealing problem is also a difficult point. [0003] Therefore, there is an urgent need to provide a novel adjustable co...
