Description
Technical field
The utility model relates to mechanical type Sewing machines, especially the flanging cloth-dragging wheel damping unit of sewing trousers-bottom machine.
Background technology
Be 201320053236.2 in the patent No., denomination of invention is the control device of sewing machine for trousers bottom curling mop gearing, adopt main shaft band movable eccentric wheel, and eccentric wheel kinematic link, connecting rod drives rocking arm again; rocking arm finally drives the axle of cloth-dragging wheel (between rocking arm and the axle of cloth-dragging wheel, unilateral bearing being housed); when sewing trousers-bottom machine normal operation; when main shaft high speed rotating reaches about 3000 revs/min, cloth-dragging wheel main shaft easily rocks, and causes speed ratio inconsistent; form needle gage and differ; needlework, apart from uneven, visually occurred length, cause sewings defective.
Summary of the invention
The purpose of this utility model adopts four steel balls to push down cloth-dragging wheel main shaft, overcomes cloth-dragging wheel main shaft and rocks, and keeps speed ratio consistent, and make needle gage consistent, needlework are apart from the flanging cloth-dragging wheel damping unit of consistent sewing trousers-bottom machine.
The purpose of this utility model adopts technical scheme, comprises cover plate, bearing, spring, steel ball, damping wheel, bearing, there is through hole the corner of aforesaid cover plate, there are four internal thread holes at middle part; There is fixing internal thread hole corner, bearing left side, middle part has four to compress internal thread heavy stand hole, there is bearing centre bore centre; There is annular groove damping wheel left side, right-hand member has radial hold-down screw internal thread hole, in the compression internal thread heavy stand hole that it is characterized in that bearing, steel ball and spring is housed successively, clamping screw successively with the internal thread hole of nut, cover plate, compress internal thread heavy stand hole and be connected, clamping screw right-hand member is adjacent with spring; Bearing right-hand member has damping wheel and bearing successively, and steel ball right-hand member is placed in the annular groove of damping wheel, has hold-down screw in the hold-down screw internal thread hole of damping wheel; Set bolt is connected with the fixing internal thread hole of bearing through the through hole of cover plate.
Further, the diameter of steel ball is equal with compression left end aperture, internal thread heavy stand hole.
Further, clamping screw, nut, cover plate internal thread hole, compress internal thread heavy stand hole axial line on one wire.
Further, the axial line of the through hole of set bolt, cover plate, the fixing internal thread hole of bearing on one wire.
It is simple that the utility model has structure, effectively pushes down cloth-dragging wheel main shaft and rock, make the features such as sewing cloth stitch uniformity.
