A machine for taking parts after casting and forming a large compressor cylinder

Abstract

The invention belongs to the technical field of compressor manufacturing and specifically relates to a casting molded large compressor cylinder block pickup machine. The casting molded large compressor cylinder block pickup machine comprises mounting columns and crawler wheels. A first mounting table and a second mounting table are mounted between the mounting columns. Guide rods and a lead screware arranged between the two mounting tables. A rotation motor is mounted on the top surface of the first mounting table and is fixedly connected with the lead screw. A lifting platform is arranged between the mounting tables. The bottom surface of the lifting platform is provided with a lifting rod. The mounting columns are provided with sliding grooves. Bearing brackets are arranged in the sliding grooves in a matched mode. The bearing brackets are fixedly connected with bearing blocks. The bearing blocks are internally provided with through holes. The bottom of the outer sidewall of each lifting rod is sunken inwards to form a step and is provided with a plurality of accommodating grooves. A limiting block is hinged to the interior of each accommodating groove. Each limiting block is fixedly connected with a first spring. When the casting molded large compressor cylinder block pickup machine is used for picking up and hoisting a large compressor cylinder block, no vertical acting force is generated between threads in screw holes of the cylinder block and the lifting rods, and the situation of thread deformation damage is avoided.

Description

technical field [0001] The invention belongs to the technical field of compressor manufacturing, and in particular relates to a machine for taking parts after casting and forming a cylinder body of a large compressor. Background technique [0002] The compressor cylinder is the key part of the compressor and is usually cast. After casting, the cylinder body needs to be taken out from the mold for surface finishing treatment. The Chinese invention patent with the application number CN201910039880.6 shows a hoisting tool for hoisting a cylinder block, including a main lifting ring, a boom and a bottom plate. One end of the boom is connected to the main lifting ring, and the other end is connected to the middle of the bottom plate. Both ends are provided with a plurality of bolt holes corresponding to the positions of the screw holes on the cylinder block. Spreader screws are inserted into the bolt holes. The spreader screws include nuts, studs and movable shafts. Connected i...

Problems solved by technology

[0004] The present invention provides a machine for picking up large compressor cylinders after casting and molding, aiming to solve the following problems when using the spreader in the prior art to pick up and hoist large compressor cylinders: (1) due to The mass of the large compressor cylinder is relatively heavy. When the studs on the sling and the screw holes on the cylinder cooperate with each other, the gap between the threads in the screw holes of the cylinder and the threads on the sling studs after the cylinder is hoisted It will generate a large vertical extrusion force, which will easily lead to thread damage and deformation, and affect the later assembly of the cylinder; (2) Due to the heavy weight of the cylinder of the large compressor, as long as the cylinder is lifted slightly, it will A large lateral load is generated on the boom, causing deformation of the boom, and even causing the breakage of the boom
