Abstract

The utility model discloses a clamping spring framework of a semiautomatic bunched net machine which comprises a movement clamping port, a fixing clamping port, a clamping seat, a bearing arranged on the clamping seat, a cam which is fixedly connected with the inner ring of the bearing, and a power axes in an axes hole of the cam. The clamping seat is fixedly connected with a rocking arm by a pin shaft. The rocking arm turns taking the pin shaft as the pivot and the roller contacting with the outer contour of the cam is fixedly connected with the rocking arm. The two ends of a tension spring are respectively fixedly connected with the rocking arm and the clamping seat. The utility model has the advantages of high working efficiency, convenient repairing and low cost.

Description

The fastening spring mechanism of semi-automatic net sewing machine

Technical field

The utility model relates to a kind of clamp mechanism, belongs to a kind of fastening spring mechanism that is applicable to the semi-automatic net sewing machine in the mattress manufacture industry.

Background technology

Semi-automatic net sewing machine on the present domestic market, its clamp clamp mechanism generally is tens and is in line that a clamp clamp mechanism is controlled by a cylinder; The clamp clamp mechanism is under cylinder control two corresponding single bed net springs to be clamped the combination back by an elongated strip spring polyphone.The clamp clamp mechanism of this net sewing machine is owing to leaked gas easily by air pressure, gas circuit, and the unsettled influence of air pressure has following weak point: 1, usually have whole row or several clamp clamp mechanism folder tight and cause the failure of string net when fastening spring because reasons such as cylinder air pressure instability or gas leakage cause; 2, nonsynchronous phenomenon takes place cause the failure of string net owing to the influence that is subjected to the action of cylinder air pressure or magnetic valve is easy to when the fastening spring clamp clamp mechanism; 3, cylinder is controlled not only cost height, and maintenance is also inconvenient.

Summary of the invention

The purpose of this utility model provides the fastening spring mechanism of a kind of energy consistent synchronously clamping, cost semi-automatic net sewing machine low, easy to maintenance.

The purpose of utility model is achieved in that it comprises live splint jaw, geometrical clamp jaw, also comprises the clamp seat, the bearing that is provided with on the clamp seat, the cam that the inner ring of bearing is fixedly connected, the line shaft of adorning in the axis hole of cam; The clamp seat is fixedlyed connected by bearing pin with rocking arm, and rocking arm is that fulcrum rotates the fixedly connected rocking arm of roller that contacts with the cam outline with the bearing pin; One end of extension spring is fixedly connected on the rocking arm, and its other end is fixedly connected on the clamp seat.

The utility model is owing to adopt cam mechanism, the cam of all fastening spring mechanisms that adorn on a crossbeam of semi-automatic net sewing machine can be driven by a line shaft and realize rotating synchronously, saved parts such as cylinder, therefore having can consistent synchronously clamping, high efficiency, easy to maintenance, advantage of low manufacturing cost.The utility model also can be regulated the clamping degree, to guarantee the quality of string net.

The specific embodiment

With reference to Fig. 1, Fig. 2, it is made up of rocking arm 1, clamp seat 2, bearing pin 3, cam 5, roller 6, extension spring 4, line shaft 8, rolling bearing 11, live splint jaw 16, geometrical clamp jaw 17.Adorn 11, two bearing 11 inner rings of bearing on the two side of clamp seat 2 respectively and be connected with the shaft shoulder at cam 5 two ends respectively, penetrate a line shaft 8 that can drive its rotation in the axis hole of cam 5.With reference to Fig. 3, rocking arm 1 middle part is arranged between clamp seat 2 two sides and is connected by bearing pin 3, and rocking arm 1 is that fulcrum rotates with bearing pin 3, and rocking arm hold-down screw 15 places the screw of rocking arm 1 to make rocking arm 1 and bearing pin 3 fastening.The roller 6 that contacts with cam 5 outlines is fixed on by nut 7 in the roller hole of rocking arm 1 rear end, and is corresponding directly over the front end of rocking arm 1 and the clamp seat 2, upper end configuration activities tong chops 16 before the rocking arm 1, configuration geometrical clamp jaw 17 directly over the clamp seat 2.Clamping adjustment screw 14 places the screw on the rocking arm 1, and its front end withstands the bolster of roller 6, regulates the gap of live splint jaws 16 and geometrical clamp jaw 17 by clamping adjustment screw 14, with realization the clamping degree of spring is adjusted.Fastening nut 7 after adjustment was finished, and roller 6 is fixed on the position that mixes up.The extension spring screw of adorning on extension spring 4 one ends and rocking arm 1 afterbody 12 is fixedlyed connected, and extension spring 4 other ends and clamp seat 2 inboard fixedlying connected contact with the outline of cam 5 all the time to guarantee roller 6.Clamp seat 2 usefulness briquettings 9 are fixedly connected on the semi-automatic crossbeam 10 of wearing the net machine by screw 13, if adjust the position of clamp mechanism on crossbeam 10, unclamp screw 13 just can be mobile fastening spring mechanism.Operation principle: each fixes tens fastening spring mechanisms on the lower and upper cross-member of semi-automatic net sewing machine, the motor transfer motion power axle of semi-automatic net sewing machine, and the cam that line shaft drives in the fastening spring mechanism rotates synchronously.Under the pulling force effect of the rotation of cam and extension spring, make roller move along the outline of cam.The motion of roller drives rocking arm, and rocking arm is that fulcrum swings back and forth with the bearing pin.With reference to Fig. 4, Fig. 5, the rotation that cam goes round and begins again makes the rocking arm band adjustable cramp and swings back and forth with state before clamping and clamping back state.When fastening spring mechanism becomes clamping back state by state before clamping, two row's springs that live splint jaw and geometrical clamp jaw will have been put are clamped together, (spring collar up and down is to clamp and go here and there net simultaneously, the fastening spring mechanism of omitting upper part in Fig. 4, Fig. 5 as shown in Figure 5 to make the circle part of spring that overlapping be arranged mutually.), the clamped radian of spring a section in tong chops becomes big, and strip spring just is serially connected two row's springs after by a slotted hole of live splint jaw and stationary clamp interruption-forming.Move forward to the precalculated position by the bed net that it is good that the net feeding mechanism on the semi-automatic net sewing machine drives string then, operating personnel sequence behind next row's spring by start button, and the bed net uncinate gyrus that former string is good of live splint jaw and next row's spring assembly clamp and go here and there net.The constantly row's of repetition spring → uncinate gyrus like this → clamping → string net → send net, up to being concatenated into a bed net up to specification.
