Automatic one-way valve element assembling machine

Abstract

The invention discloses an automatic one-way valve element assembling machine. The automatic one-way valve element assembling machine structurally comprises a conveying belt, a base, a fixing plate, a clamping jaw and side plates, the conveying belt is connected to one end of the base, the two side plates are connected to the other end of the base, the fixing plate is connected to the side plates, the clamping jaw is installed on the fixing plate, and a clamping mechanism is provided with a pipe hoop and an auxiliary device. The pipe hoop and the auxiliary device are matched on a progressive body, when the outer circumference of a spring is welded to a valve element, the bottom of the spring can be bent in the auxiliary device due to pressing and rotate and hook in the auxiliary device, the auxiliary device is driven to run in and drive the pipe hoop to rotate upwards to be attached to the outer circumference of the spring, and the risk that the spring is disjointed during welding is avoided.

Description

technical field [0001] The invention relates to the field of automatic machinery, in particular to an automatic assembly machine for a check valve core. Background technique [0002] Check valves have been widely used in hydraulic and pneumatic transmissions. The check valve spool includes a spool and a spring. Due to the small size of the spool and spring. For a long time, the assembly of the check valve spool has relied on manual operations, which cannot meet the needs of increasing technological development at all, and the disadvantages of manual assembly are increasingly exposed. It is necessary to use automatic equipment to realize the automatic operation of the check valve spool; the jaws of the existing check valve spool automatic assembly machine grab the spool and the spring for grasping and welding, because the spring is a single superimposed structure, when the spring It is easy to bend on the inside of the claw with the minimum stiffness, and has a large tensile...

Problems solved by technology

For a long time, the assembly of the check valve spool has relied on manual operation, which cannot meet the needs of increasing technological development at all, and the disadvantages of manual assembly are increasingly exposed.

It is necessary to use automatic equipment to realize the automatic operation of the check valve spool; the jaws of the existing check valve spool automatic assembly machine grab the spool and the spring for grasping and welding, because the spring is a single superimposed structure, when the spring It is easy to bend on the inside of the claw with the minimum stiffness, and has a large tensile stiffness and bending stiffness in the other direction, so that the outer circumference of the spring will match its own stiffness when it is welded with the valve core. A disjointed power is brought to the spring limited and pressed at the end of the claw, which makes it difficult for the center of the valve core and the spring to communicate accurately on a concentric circle, which not only affects the appearance of the finished check valve, but also greatly reduces its performance.
