Hoisting tool for sleeve workpiece

Abstract

The patent discloses a hoisting tool for a sleeve workpiece. The hoisting tool comprises supporting seats, supporting rods, a fixed supporting seat, a hoisting ring, ear plates and adjustable screw rods. The hoisting ring is fixed on the fixed supporting seat. The adjustable screw rods are arranged on the supporting rods. The ear plates are arranged on the fixed supporting seat. One end of the supporting rod is hinged with the supporting seat by a bulb of the adjustable screw rod while the other end of the supporting rod is hinged with the ear plate on the fixed supporting seat by a pin shaft. According to the hoisting tool for the sleeve workpiece, the hoisting tool is supported by three points and capable of hoisting workpieces stably. The length of the supporting rod can be adjusted within a certain range by the screw threads, so that the supporting rod can adapt to the hoisting of sleeves within a certain diameter range. An optimal included angle between the axial line of the supporting rod and the axial line of the fixed seat can be kept by adjusting so as to maintain a good working state. The supporting rod is hinged with the fixed supporting seat by the pin shaft and the supporting rod can swing up and down freely, so that the hoisting tool has the functions of freely closing and opening to fulfill the purpose of convenient hoisting.

Description

Technical field [0001] The invention relates to a hoisting tool for a sleeve workpiece. Background technique [0002] Sleeve type compensator is one of the leading products of our company's compensator products. The core tube is the core component of the sleeve compensator. The outer cylindrical surface needs to be processed and the luminosity has high requirements.

[0002] The sleeve compensator is one of the leading products of our company's compensator products. The core tube is the core component of the sleeve compensator. The outer cylindrical surface needs to be finished, and the luminosity also has high requirements. However, the manufacturing process of the core tube is relatively complicated. , There are many processes, from blanking-rolling-welding-round calibration-rough machining-finishing-surface polishing or calendering-chrome plating-surface polishing, there are many assembly processes, such as Core tube and sealing ring set--core tube and jacket set--inner end packing or molded graphite ring assembly--seal packing assembly-outer end packing or molded graphite ring assembly-one ring assembly-one ring welding --Inspection--Friction Test--Pressure Test--Surface Treatment, etc. After so many processes, multiple turnovers and multiple hoistings are required. Core tubes with high precision and surface gloss requirements are easily bumped and scratched , especially from chrome plating to the final pressure test of the product, the core tube or the compensator as a whole needs to be hoisted vertically, and the ordinary sling is directly stuck on the movable end of the core tube, where the outer cylindrical surface of the core tube is directly The scar on the card seriously affects the sealing performance of the compensator
