Spring sorting machine

Abstract

The invention provides a spring sorting machine comprising a rack. The spring sorting machine is characterized by comprising a compression unit, a working unit, a material conveying unit, a power unit and a classifying unit, which are mounted on the rack, wherein the compression unit comprises an upper pressing head, an air cylinder, an L-shaped mounting plate and an air cylinder mounting base; the working unit comprises a bottom plate and a worktable; a sensor and a lower pressing head are mounted in circular holes on the worktable; a power shaft and a reversing shaft are mounted at the lower part of the bottom plate; a cylindrical gear is mounted at each one of the lower ends of the power shaft and the reversing shaft, and the lower ends of cranks; two pairs of the cylindrical gears at the outermost side are connected with a left connecting rod and a right connecting rod through the corresponding cranks and synchronously and oppositely drive a left clamping block and a right clamping block; the material conveying unit comprises an interval material feeding device; and the interval material feeding device comprises a material conveying pipe and an interval material feeding unit is arranged at the lower part of the interval material feeding pipe. The spring sorting machine has the advantages of safety and reliability, high automation degree, high working efficiency, simplicity in operation and convenience for utilization, and is suitable for spring manufacturers to use.

Description

technical field

[0001] The invention relates to a spring separator. Background technique

[0002] There are multiple parameters of the spring that need to be tested before leaving the factory, such as elastic coefficient, stiffness, flexibility, etc. Among them, the elastic coefficient, also known as load, is the most common detection index. Spring manufacturers need to divide the mass-produced springs of the same specification into multiple grades according to the difference in elastic coefficient for different purposes. The traditional classification method relies on manually placing springs on the testing machine one by one, testing and classifying. The workload is heavy and the efficiency is low. Workers are easily bored in the face of a large number of repetitive testing tasks, and the reliability cannot be guaranteed. For example, Chinese patent ZL01227728.2 discloses a spring sorting machine and the helical compression spring sorting machine disclosed in Chinese pate...
