Twin-cylinder rotary centering machine

Abstract

This utility model provides a double-cylinder rotary centering machine, including a machine support frame and a placement plate. The top of the machine support frame is fixedly connected to a machine table, and a lifting plate is embedded on one side of the top of the machine table. A first cylinder is fixedly installed at the bottom of the machine table. This utility model uses a drive motor to drive a divider for indexing. Combined with the first cylinder, the lifting plate and the workpiece are pushed up to a predetermined height and positioned and clamped. Subsequently, the rotary centering mechanism drives the workpiece to rotate at high speed for dynamic centering correction, effectively eliminating the inherent deviations of traditional manual or static centering by integrated machines. The locking motor outputs torque through a reducer, and the locking head completes the screw tightening, ensuring that each assembly unit achieves consistent torque and concentricity requirements. This fundamentally solves the problems of unqualified pump feel, abnormal noise, and short lifespan caused by poor centering, significantly shortening the assembly time of a single piece and reducing the waiting and adjustment time between processes.

Description

Technical Field

[0001] This utility model mainly relates to the field of mechanical manufacturing and automation technology, specifically a double-cylinder rotary centering machine. Background Technology

[0002] The dual-cylinder rotary centering machine is an automated device used for assembly by dual-cylinder pumps. It performs dynamic centering correction by rotating the workpiece at high speed and automatically completes the clamping and screw tightening operations, ensuring extremely high concentricity and consistent assembly torque.

[0003] Currently, most technologies employ manual operation or machine assembly, resulting in poor centering accuracy, low consistency, and low efficiency. Traditional manual centering methods heavily rely on operator experience, leading to significant subjective biases and making it difficult to guarantee the concentricity of each workpiece. Machine assembly primarily uses static centering methods, lacking effective dynamic rotation correction methods. This makes it impossible to eliminate subtle dimensional and positional errors under simulated actual working conditions, resulting in assembly pump products prone to quality problems such as poor feel, abnormal operating noise, and premature wear. This limits the improvement of the overall production cycle and makes it difficult to meet the demands of modern mass production and high-quality manufacturing. Utility Model Content
