Problems solved by technology

[0002] In the process of steel structure production, it is often encountered that some cylinders with unequal diameters are docked, commonly known as stepped cylinders. In order to ensure that the two cylinders with unequal diameters are concentric, two types of V-shaped positioning blocks with unequal heights are usually used. Positioning and centering, this positioning method is a waste of time, and at the same time the production efficiency is relatively low

Abstract

The invention relates to a stepped cylinder centering device. The stepped cylinder centering device is characterized in that two side arm plates are machined first, the arm plates are connected with two ends of the top transverse connecting plate through bolts, and the middle position of the top transverse connecting plate is divided into two half parts to be welded to a nut. A screw rod is screwed into the nut, a positioning block is welded at the bottom of the screw rod, the positioning block consists of positioning plates and round steel, the positioning plates are connected with the roundsteel through welding, a hole is drilled in one side of each positioning plate and threaded, and a screw is screwed into each hole. Two ends of each positioning plate are provided with middle transverse connecting plates in a welded mode, and the middle transverse connecting plates are connected with the two side arm plates through side connecting plates with bolts respectively to form a set of linkage mechanism. Two sets of positioning blocks are welded below the two side arm plates and at the position with an included angle of 120 degrees formed with the screw rod, a large-diameter cylinderis placed between the arm plates, the screw rod is rotated, and the three sets of positioning blocks are used for clamping the large-diameter cylinder; and then a small-diameter cylinder is placed between the arm plates, and three sets of screws are adjusted to enable the axes of the two cylinders to coincide.

Description

technical field [0001] The patent of the present invention relates to a stepped cylinder centering device, which is mainly used in the field of steel structure manufacturing. Background technique [0002] In the process of steel structure production, it is often encountered that some cylinders with unequal diameters are docked, commonly known as stepped cylinders. In order to ensure that the two cylinders with unequal diameters are concentric, two types of V-shaped positioning blocks with unequal heights are usually used. Positioning and centering, such a positioning method is a waste of time, and at the same time, the production efficiency is relatively low. Contents of the invention [0003] The purpose of the patent of the present invention is to improve the production efficiency and reduce the labor intensity of workers, and to invent a step cylinder centering device with simple operation and reliable quality. [0004] The purpose of the present invention is achieved ...
