Abstract
The utility model discloses a digitalized driving device for a cotton comber nipper, which comprises a nipper driving shaft, a crankshaft fixedly connected with the nipper driving shaft, a sliding sleeve fixedly connected with the crankshaft, and a sliding rod which can be connected with the sliding sleeve in a sliding mode under the driving of the crankshaft, wherein the sliding rod is fixedly connected with the nipper shaft by a connecting rod; the rear end of a rear oscillating arm is fixedly connected with the nipper shaft; the other end of the rear oscillating arm is hinged and connected with one end of the nipper by a hinge; the other end of the nipper is hinged and connected with one end of a front oscillating arm by a hinge; the other end of the front oscillating arm is hinged to a cylinder shaft by the hinge; the cylinder shaft and the nipper driving shaft are arranged on the same axis; and one end of the nipper driving shaft is connected with the output shaft of a servo motor. After the digitalized driving device for the cotton comber nipper is adopted, the process cooperation among the cotton comber nipper, the cylinder and a detaching roller can be satisfied, a moving track can be adjusted, and limitation on the characteristics of the servo motor due to the improvement of the vehicle speed can be satisfied.
Description
Technical field
The utility model relates to the drive unit in a kind of textile machine, particularly cotton comber nipper digitlization driving method and device.
Background technology
At present, cotton comber nipper transmission device adopts following dual mode: 1. the pure mechanical mechanism of being made up of crank block linkage and four connecting rod endplay devices, two covers, four connecting rods; 2. add the servo direct driving mechanism that endplay device is formed by the direct drive rocker of servomotor.When pure mechanical mechanism rotated in the external force driving, nipper swung back and forth under the effect of two cover quadric chains, and this mechanism structure is fairly simple, part precision is low, and shortcoming is nipper controlled poor, unfavorable high speed when motion; Servo direct driving mechanism is that the direct drive rocker of servomotor mechanism swings back and forth nipper, and this mechanism structure is simple, the nipper controllability is strong, but owing to is that reciprocating motion is strict to the servomotor characteristic requirements, cost is high.
To sum up, the running orbit of its critical component of transmission of existing cotton comber employing Purely mechanical is unadjustable, and adopts servomotor directly to drive swing arm, and the raising of the speed of a motor vehicle can receive the restriction of servomotor characteristic again.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of prior art; Position, speed, acceleration in a kind of convenient control cotton comber clamped plate motion are provided; Make the movement locus of combing machine nipper can satisfy cylinder combing and the requirement of detaching roller separation processes, also can satisfy the cotton comber nipper digitlization drive unit of the requirement of the cotton comber speed of a motor vehicle that improves constantly simultaneously.
The cotton comber nipper digitlization drive unit of the utility model; It comprises the nipper driving shaft; The slide bar that the crank that is fixedly linked with the nipper driving shaft, the sliding sleeve that is fixedly linked with crank, the driving through described crank can be slided and link to each other with said sliding sleeve; Described slide bar is fixedly linked through connecting rod and tongs plate axis; Rear-swing arm one end and described tongs plate axis are fixedly linked and an end of the rear-swing arm other end and nipper is hinged and connected through hinge, and an end of the other end of described nipper and front swing arm is hinged and connected through hinge, and the other end of described front swing arm is hinged on the cylinder axis through hinge; Cylinder axis and nipper driving shaft are coaxially set, and an end of nipper driving shaft links to each other with the output shaft of servomotor.
Adopt the beneficial effect of this device to be:
Adopt servo-drive slider-crank mechanism and the mode that mechanical swing arm combines, satisfy the cotton comber nipper and cooperate with the technology of cylinder, detaching roller, and the running orbit scalable; Optimization through movement locus can reduce nipper at the volley because the closed noise that produces reaches the vibration that the reduction combing is moved and produced in the high speed production engineering; Adopt the transmission that combines mechanical and electrical equipment, servomotor moves in a circle, and the drive characteristic of servomotor reduces, and can satisfy the speed of a motor vehicle and improve the restriction to the servomotor characteristic.
Description of drawings
Accompanying drawing is the structural representation of the cotton comber nipper digitlization drive unit of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done to describe in detail.
Cotton comber nipper digitlization drive unit like the utility model shown in the drawings; It comprises nipper driving shaft 1; The slide bar 4 that the crank 2 that is fixedly linked with the nipper driving shaft, the sliding sleeve 3 that is fixedly linked with crank, the driving through described crank can be slided and link to each other with said sliding sleeve, described slide bar is fixedly linked through connecting rod and tongs plate axis 5.Rear-swing arm 6 one ends and described tongs plate axis are fixedly linked and an end of the rear-swing arm other end and nipper 7 is hinged and connected through hinge; One end of the other end of described nipper and front swing arm 9 is hinged and connected through hinge; The other end of described front swing arm is hinged on the cylinder axis 8 through hinge; Cylinder axis and nipper driving shaft are coaxially set, and an end of nipper driving shaft links to each other with the output shaft of servomotor.Described hinge can adopt bearing pin and bearing iron hinge structure, also can adopt the bearing iron hinge structure.
A kind of embodiment as the utility model; Have sliding eye on the described sliding sleeve; Described slide bar 4 is inserted in the sliding eye that can be slidingly matched with slide bar 4; Certainly the crank Slide bar structure can also adopt existing other versions, as: cam link mechanism, six bar mechanism, eight-bar linkage etc.
Being installed in the cotton comber according to existing structure of cylinder axis described in this structure gets final product.
This device running is following:
Servo controller drives the nipper driving shaft according to the clamped plate motion track of setting; Driving tongs plate axis through the slider-crank mechanism that is made up of crank, sliding sleeve, slide bar swings back and forth according to the movement locus of setting; The four connecting rod swing arm mechanisms that tongs plate axis is formed through rear-swing arm, nipper, front swing arm drive nipper according to the movement locus motion of setting, and realize that the digitlization of cotton comber nipper drives.
The motion of the servomotor of the utility model is decided by the curve data of controller input servo-driver; Driven by servomotor nipper driving shaft is by predefined curvilinear motion; And then the control nipper is by predefined curvilinear motion, so each position of the motion of nipper, speed, acceleration etc. can be satisfied the requirement of whole combing machine technology fully.
