Description
Technical field
The utility model belongs to sewing machine technique field, is related to a kind of presser foot drive.
Background technology
Sewing machine is the machine for being sutured sewing by suture, including needle bar mechanism, Yarn taking-up mechanism, feed mechanism, compression
Mechanism and presser bar lifting mechanismses etc..Hold-down mechanism is again feeding pressure mechanism, refers to the mechanism for applying pressure to sewing.Pressure foot lifting machine
Structure refers to release the mechanism to sewing pressure.Presser foot drive i.e. can opposite joint material apply pressure and can enough release sewing pressure
Power.Template machine is a kind of high sewing machine of automaticity, sets XY feed mechanisms to carry out auxiliary feeding to sewing on template machine,
Because sewing quality is soft, it is necessary to which sewing is placed in template, template is connected on XY feed mechanisms, then passes through auxiliary presser foot
Template is pressed on platen so as to which sewing is pressed in template.
Chinese patent literature data, which discloses, proposes a kind of template sewing machine presser feet, [application number：201310375870.2；
Authorization Notice No.：CN103451858A], including the pressing plate company that pressing plate and one end are fixed on pressing plate, the other end and cylinder are fixed
Contact pin, be provided with pressing plate connection sheet it is vertical run through elongated hole, pressing plate is connected by penetrating elongated hole with nut using screw
Piece is fixed on cylinder.The pressing plate mentioned in the document is exactly auxiliary presser foot, and the piston rod of pressing plate connection sheet and cylinder connects.
When auxiliary presser foot compresses template, template on platen when moving horizontally and rotating, meeting between template and auxiliary presser foot
Produce frictional force, frictional force, which is acted on auxiliary presser foot, can make the cylinder piston rod that is connected with auxiliary presser foot by moment of torsion and curved
Square, so as to influence the service life of cylinder, reduce the service life of whole mechanism.
The content of the invention
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, it is proposed that a kind of presser foot drive,
The technical problem of solution is that the service life for how making mechanism is grown.
The purpose of this utility model can be realized by following technical proposal：
A kind of presser foot drive, on casing, including the cylinder being fixed on casing, the piston rod of the cylinder
On be fixedly connected with presser feet connecting plate, be fixedly connected with auxiliary presser foot on the presser feet connecting plate, it is characterised in that the casing
On be fixed with guide plate, the guide groove being correspondingly arranged with guide plate is offered on the upper surface of the presser feet connecting plate, it is described to lead
It is inserted into plate in guide groove, the piston rod of the cylinder can drive presser feet connecting plate to be moved up and down on guide plate, described
Having two in the side wall of guide groove, be oppositely arranged be in plane spigot surface, and it is in plane to have two on the guide plate
Blocking surface, two spigot surfaces correspond with two blocking surfaces respectively, and each spigot surface abuts in corresponding stop
On face.
