Servo control pitch forming mechanism of automatic spring coiling machine

Abstract

The invention relates to a servocontrol thread pitch forming mechanism for an automatic spring coiling machine. An output shaft of a servo motor of the forming mechanism is connected with a height cam through a key, the height cam rotates by the same angle around the output shaft of the servo motor, the lift range of the cam is identical, the bottom end of a connecting base is connected and arranged on a linear guide rail through threads, the other end of the connecting base is locked on a guide lever through a locking screw; the connecting base is provided with a pin hole which is provided with a pin shaft inside, a driven bearing is arranged on the pin shaft, and the guide lever is arranged on a linear bearing arranged on a front wall board and a rear wall board; and a compression spring is arranged at the rear part of the guide lever, and the driven bearing is stuck to the cam surface of the height cam all the time due to the combined action of the compression spring and the height cam. The proposal helps people convert the produced spring flexibly and rapidly, and ensures that different cams are not changed even if springs with different specifications are to be produced, thereby greatly saving the debugging time and reducing the requirements on the skill of an operator.

Description

Technical field: [0001] The invention relates to the field of mattresses, and relates to a servo-controlled pitch forming mechanism of an automatic spring coiling machine capable of realizing digital control without frequent replacement of pitch cams. Background technique: [0002] The automatic equipment for producing biconical mattress springs has been produced in my country for about five years, but the existing automatic equipment mainly relies on cams and connecting rods to control the spring pitch. Although only using the cam to control the pitch of the mattress spring can realize continuous self-efficient automatic production, it also has its limitations. This is manifested in the fact that the shape of the cam limits the variation of the spring pitch to a certain extent. Because the change of mattress spring pitch will have a great impact on the elastic feeling of the finished mattress, customers often need springs of different shapes to meet the needs of different ...

Problems solved by technology

Therefore, when the same machine produces springs with different pitch shapes, it is necessary to replace different pitch cams, which greatly increases the labor intensity of the operators, reduces the efficiency, and increases the skill requirements for the operators.
