Supporting mechanism used for thread forming machine

Abstract

The invention relates to a supporting mechanism used for a thread forming machine. The supporting mechanism comprises a table top, a sliding set, a bearing set and an adjusting set, wherein rails arearranged on the table top; the sliding set comprises two sliding rods which slide in the rails and are arranged in a front-rear manner, and the extension direction of the sliding rods is perpendicularto the extension direction of the rails; the bearing set is disposed in a bearing base above the two sliding rods and in a limit box above the bearing base, the limit box is of a rectangular frame structure, meanwhile two supporting frames are arranged in the limit box in a left-right manner, and idler wheels are arranged in the supporting frames; the adjusting set comprises a screw horizontallypenetrating through the limit box; a handle is arranged at the end, disposed on the outer side of the limit box, of the screw; the end, disposed on the inner side of the limit box, of the screw is inthreaded connection with a supporting frame of the screw; the supporting frame which is away from the screw is fixedly connected with the limit box; and the supporting frame which is close to the screw moves frontwards and backwards in the rotation direction of the screw. The supporting mechanism has the advantage of being capable of supporting motion bolts of different diameters.

Description

Technical field: [0001] The invention relates to a support mechanism for a thread forming machine. Background technique: [0002] At present, there is a marine low-speed diesel engine with a tonnage of 1850t. The connecting parts used to connect the piston and the piston rod in the cylinder of the diesel engine are generally made of high-quality special alloy steel. Screw thread, the moving connector also moves with the piston and piston rod while connecting, so it is commonly called a moving bolt in the industry. [0003] Because the length of the moving bolt is 2.7 ~ 3m, and some even reach 10m, and the threads at both ends of the moving bolt are extruded successively (that is, one end of the moving bolt is extruded and formed on the thread forming machine first). thread, and then use a crane to turn the moving bolt and then extrude the thread at the other end), so when extruding the thread at one end of the moving bolt, the other end (ie the free end) needs a support mec...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the applicant has invented a support mechanism specially used to support the moving bolt. The supporting mechanism is in rolling contact with the moving bolt through two rollers, thereby realizing the support for the moving bolt. Fixed non-adjustable, can only support moving bolts within a fixed diameter range
