Description
Technical field
The utility model relates to a kind of nipper mechanism of combing machine, but relates in particular to a kind of novel nipper mechanism of combing machine that the axle complete cycle rotates that clamps.
Background technology
Since the Englishman received Randy Smyth creation swing nipper formula combing machine, the nipper mechanism oscillating motion form of combing machine was leveraged to the present always.At present, the nipper mechanism of existing combing machine all is the reciprocally swinging formula both at home and abroad, and the oscillating motion of its pincers axle is driven by the complete cycle gyration of cylinder axis by suitable mechanism.
Figure 1 shows that the nipper mechanism sketch of existing combing machine, its nipper plate is driven by eccentric guide-bar mechanism of crank-swinging and double-lever mechanism, is mainly the O. cylinder axis, the OA. crank, AB. slide block, the eccentric guide rod of BCQ., Q. clamps spool, DQ. fork after, HD. nipper plate pincers bed, the OH. front roll bar is formed; Nippers is driven by the hinge point E on the connecting rod HD, is mainly JFE. nippers (seat), the long compressible spring bar of FK. bar, and the KG. eccentric rod, the G. eccentric shaft constitutes; Eccentric KG drives (not shown) by swing pincers axle Q by set of gears mechanism.When cylinder (R) with cylinder axis (O) when rotating, cylinder axis (O) drives crank-sliding block-guide-bar mechanism (OABCQ) motion, make tongs plate axis (Q) back and forth rotate, reciprocally swinging before and after back fork (DQ), nipper plate pincers beds (HD) and the front roll bar (OH), thereby make the nippers (JFE) that is articulated on the nipper plate pincers beds (HD) open and close and suitable pressurization, realize combing by technological requirement.
Obviously, the motion of this combing machine is mechanical linkage, not only transmit moving line length, conversion motion complexity etc. and be unfavorable at a high speed, but also be difficult at the cotton fiber combing of different cultivars neatly the adjusting process parameter strengthen the spinning suiting of combing machine.To this, Chinese invention patent application number 200810208037.8, a kind of digitized discrete cell driving combing machine is disclosed, the individual motor that has realized combing machine unit multiaxis drives, not only make the combing machine transmission mechanism simplify greatly, but and more importantly be to make the technology kinematic parameter independent regulation of each workpiece of combing machine, and then can greatly improve the spinning suiting performance of combing machine, and help the raising of combing sliver quality.
But combing machine realizes that digitized discrete cell drives, and associated mechanisms also needs to do corresponding change, otherwise can bring new problem.As clamp axle and carry out independent driven by servomotor, constant as if former nipper mechanism, then driven by servomotor pincers axle just need satisfy the requirement of high-speed high-power reciprocally swinging drive controlling, and also there is the bottleneck that needs breakthrough in this regard in present servomotor technology.
The utility model content
But technical problem to be solved in the utility model provides a kind of novel nipper mechanism of combing machine that the axle complete cycle rotates that clamps, the pincers axle of this mechanism can be done unidirectional complete cycle revolution, can avoid occurring driven by servomotor and must satisfy the technical bottleneck problem that high-speed high-power reciprocally swinging drive controlling requires.
Solve the above-mentioned technical problem that nipper mechanism of combing machine exists, but and provide a kind of novel nipper mechanism of combing machine that the axle complete cycle rotates that clamps.
For achieving the above object, the technical solution of the utility model is as follows:
But the novel nipper mechanism of combing machine that pincers axle complete cycle rotates, comprise cylinder axis, front roll bar, cylinder, nippers, compressible spring suspension rod, eccentric rod, suspension rod axle, nipper plate, crank, tongs plate axis composition, and cylinder axis and cylinder are affixed, the front roll bar sky is enclosed within on the cylinder axis, it is characterized in that, but comprise the whirligig that bearing rotates, but an end of the whirligig that bearing rotates be connected on the nipper plate, the other end is connected tongs plate axis.
But the whirligig that described bearing rotates is short crank.
But the whirligig that described bearing rotates is an eccentric disc.
Remove described eccentric rod, compressible spring suspension rod and suspension rod axle directly link together.
Whirligig is by the unidirectional complete cycle variable speed drives of servomotor.
Its nipper plate mechanism shortens to the crank that the energy complete cycle rotates with the back fork in the nipper plate mechanism scheme of existing combing machine, corresponding front roll bar length is constant as far as possible, the nipper plate bar suitably increases, clamp axial back upper place and move, make the double-lever mechanism of former nipper plate change over a short crank and rocker mechanism.Motor is directly installed on and does unidirectional complete cycle driving on the tongs plate axis, the existing combing machine pincers of cancellation simultaneously axle former driving mechanism---crank eccentric swing guide-bar mechanism, and the former scheme of corresponding nippers mechanism keeps constant substantially, the only relevant relative nipper plate of dimensional structure mechanism does suitably to adjust, nipper mechanism can open and close by technological requirement to adapt to up and down, when jaw is closed suitable pressurization and realize approximate etc. space in the wrong.
The nippers eccentric rod of nipper mechanism cancellation (simultaneously, the also corresponding cancellation of former corresponding driving mechanism), and the compressible spring suspension rod directly is contained on the suspension rod axle, and the pincers axle is watched compound machine for unidirectional variable-ratio complete cycle rotation and is driven.This implementation can be by adjusting nippers appropriate authority size and suitable definite pincers axle speed change rotating drive rule, can realize between nipper when appropriate interlock equally and make nipper mechanism keep motionless substantially when combing and make the snap-in force size be similar to constant.
Beneficial effect:
1, by shortening the back fork, make nipper mechanism become short crank and rocker mechanism by former double-lever mechanism, and by the former pincers axle of cancellation driving mechanism---crank eccentric swing guide-bar mechanism, not only simplified pincers axle driving mechanism but also made nipper that former to be with the front and back reciprocating motion that main transformer has become existing to swing up and down motion, not only help reducing complete machine oscillation, and the unidirectional complete cycle rotation of pincers axle helps driven by servomotor, helping nipper technology kinematic parameter and last nipper plate opens, the best of closing time is regulated, and then can strengthen the spinning suiting performance of combing machine, improve combing machine dynamic property and combing quality.
2, realize the swing of nipper mechanism with short crank and rocker mechanism
Rotate with the variable-ratio complete cycle and to watch compound machine, jaw is opened and closed by best combing requirement in good time and when jaw is closed, realize suitably pressurization and the combing of spacing such as approximate the control that crank-motion drives.
3, the eccentric rod in its nippers mechanism is removed (simultaneously, the also corresponding cancellation of former corresponding driving mechanism), the upper end with the compressible spring suspension rod directly is contained on the suspension rod axle then, helps the nipper mechanism system and further simplifies.Watching compound machine because of the pincers axle by unidirectional variable-ratio complete cycle rotation is driven, this implementation can be by a suitable adjustment nippers relative dimensions and a pincers axles speed change rotating drive rule, can realize equally opening and closing between nipper when appropriate, approximate etc. the constance force pressurization and etc. the combing of spacing.
4, lack crank and change with eccentric disc and replace, be convenient to processing, make and installation.
