Description

Technical Field

[0001] The utility model relates to the technical field of multi-stage screening devices, in particular to a multi-stage screening device for producing and processing oil pump nozzle springs. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. They are generally made of spring steel. The spring needs to be tested after processing. It can only be used after passing the test. Traditional testing methods are mostly manual testing and screening, and their detection efficiency is low. In order to improve this situation, a multi-stage screening device for the production and processing of oil pump nozzle springs is proposed.

[0003] For example, a multi-stage screening device for spring production and processing disclosed in the authorization announcement number CN218925385U includes a feeding turntable installed at the upper end of a supporting chassis, a servo motor installed at the lower end of the supporting chassis, and the output shaft of the servo motor is drivingly connected to the feeding turntable, and support leg mounting points are arranged around the lower surface of the supporting chassis, and also includes: a loading trough, which is arranged inside the surrounding of the feeding turntable, and a push rod positioning seat, which is installed at the middle position of the feeding turntable;

[0004] Although it realizes the push-type screening method, when the feeding turntable rotates normally, the limit baffles of the waste flow channel and the defective flow channel are in a closed state, preventing the qualified springs from sliding off the waste flow channel and the defective flow channel before moving to the unloading conveyor. When the camera detects the waste spring or the defective spring, the feeding turntable can rely on the loading trough to transfer the waste spring or the defective spring to the waste flow channel or the defective flow channel port, and the controller drives the stepper motor of the corresponding port to operate, and the limit baffle is driven to rotate and open under the action of the belt drive, and the electric push rod at the rear end of the loading trough drives the arc push plate to move forward, so that the waste spring or the defective spring slides into the waste flow channel or the defective flow channel, and enters the waste storage box and the defective storage box along the flow channel. Compared with the drop-type screening, the process is smoother and the transmission process is not prone to jamming.

[0005] However, the problem that the existing multi-stage screening device is not conducive to the convenient movement of the clamping input spring and the convenient linkage rotating closed output channel during use is not solved, which affects the accuracy of screening. Utility Model Content
