Abstract

The utility model belongs to sewing machine technology and particularly designs a cam mechanism capable of simultaneously driving a plurality of members to conduct mechanical motion for purpose of simultaneously completing multiple mechanical actions. In the utility model, the design of maximum space utilization is implemented in the limited space of a shell, a plurality of cam mechanisms needing to be driven by a plurality of motors are gathered together, and one motor drives one composite cam mechanism. The cam mechanism is characterized by the design of a cam that acts together with the connected mechanism to simultaneously accomplish multiple mechanical actions, thus achieving the purposes of simultaneously driving a trimming connecting rod to push a trimming mechanism to conduct trimming action, a pressure foot lifting connecting rod to push a pressure foot lifting mechanism to conduct pressure foot lifting action, and a medium pressure lifting crank to push a medium pressure lifting mechanism to conduct medium pressure lifting action by driving the motor and the cam.

Description

A kind of cam mechanism
Technical field:
The utility model belongs to sewing machine technique, has particularly designed a kind of cam mechanism that a plurality of members make mechanical movement of can realizing simultaneously driving.
Background technology:
Cam is meant to have by output movement learns the curve of requirement design of characteristic and dynamics or curved surface profile and as the member of high accessory element.Cam is made continuous constant speed usually and is rotated, and driven member makes it obtain the motion of certain rule according to the instructions for use design. and cam mechanism can be realized complicated requirement, is widely used in the various automated and semi-automatic mechanical devices.Mechanical component of a general cam mechanism driving makes mechanical movement, and reaches the purpose that drive member is finished certain action, drives member respectively by a plurality of cam mechanisms and makes mechanical movement, and finishes the series mechanical action.
The utility model content:
The utility model has designed and a kind ofly can drive the cam mechanism that a plurality of members make mechanical movement simultaneously, to reach the purpose of finishing a plurality of mechanical actions simultaneously.
The utility model comprises housing, drive motors, motor hold-down screw, motor shaft, cam, cam hold-down screw, trimming crank, presser foot lifter crank, lifts middle presser feet crank, it is characterized in that having designed a cam, make it finish a plurality of mechanical actions simultaneously with the mechanism that links to each other.Carry out maximized space utilization design in the confined space of the utility model in housing, to need a plurality of motor-driven a plurality of cam mechanisms to be brought together, by multiple mounted cam mechanism of a driven by motor, realize driving simultaneously the trimming crank drive thread cutting mechanism carry out the trimming action, drive the presser foot lifter crank drive presser foot lifter mechanism carry out the presser foot lifter action and drive lift in the presser feet crank drive lift in presser foot device lift in the purpose of presser feet action.Wherein the effect of thread cutting mechanism is to carry out the trimming action after finishing making action, presser foot lifter mechanism drive the lifting of presser feet and lift in presser foot device drive in the lifting of presser feet.
A kind of cam mechanism described in the utility model has designed a compound cam in the confined space of housing, and a shared servomotor drives, and provides cost savings to the full extent, makes whole housing lighter again, and mechanical structure is compact more.Realized simultaneously saving energy and reduce the cost, and guaranteed trimming action, presser foot lifter action and lifted the synchronous of middle presser feet action, can increase work efficiency effectively.
Description of drawings:
Fig. 1 is the utility model stereogram;
Fig. 2 is the utility model cam front view;
Fig. 3 is the utility model camshaft mapping;
The specific embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3, drive motors 2 is installed on the housing 1, use motor hold-down screw 3 fastening again, produce displacement when preventing drive motors 2 work.Then cam 5 is contained on the motor shaft 4, limits its axially-movable with cam hold-down screw 6 again, so just can be rotated motion by the rotating band moving cam 5 of drive motors 2.Three curved surface profiles of learning the requirement design of characteristic and dynamics according to output movement are arranged on cam 5, they are respectively applied for and drive trimming crank 7, presser foot lifter crank 8 and lift in presser feet crank 9, trimming crank 7, presser foot lifter crank 7 and lift in presser feet crank 9 respectively have a fulcrum to be fixed on the housing 1, one end is connected with cam 5, the other end connects thread cutting mechanism and presser foot lifter mechanism respectively, wherein trimming crank 7 is used to drive thread cutting mechanism, presser foot lifter crank 8 is used to drive presser foot lifter mechanism, presser feet crank 9 is used for driving and lifts presser foot device in lifting, and can finish trimming simultaneously like this under the drive of drive motors 2, presser foot lifter and lift in three actions of presser feet.
