Abstract

The invention discloses a device for testing fatigue of a knitting needle spring piece in a computerized flat knitting machine. The device comprises a motor, a motor fixing base, a fixing sleeve, a rotary rod, a knitting needle fixing plate, a fixing block and a limiting block. A round installing hole is formed in one side of the motor fixing base, the motor is fixed to the motor fixing base, and a motor shaft penetrates through the round installing hole; the fixing sleeve is round, and the motor shaft is sleeved with the fixing sleeve; the rotary rod is fixed to the circumference of the fixing sleeve; a rectangular groove is formed in the middle of the motor installing base; the knitting needle fixing plate is installed on the motor installing base through a screw, and the front end of the knitting needle fixing plate is pressed on the portion above the rectangular groove; the fixing block is wholly of an L-shaped structure, and the fixing block is fixed to the motor installing base; the limiting block is fixed to the port of the rectangular groove. According to the device, a single-chip microcomputer is used for quantitatively controlling the rotating speed and the rotating frequency of the motor regularly, the rotary rod is made to simulate the state of the spring piece used for knitting of a knitting needle when the rotary rod passes the knitting needle spring piece, and the performance of the knitting needle spring piece is tested.

Description

The fatigue test device of knitting needle spring leaf in a kind of Computerized flat knitting machine
Technical field
The invention belongs to technical field of knitting machinery, particularly the fatigue test device of knitting needle spring leaf in a kind of Computerized flat knitting machine.
Background technology
Knitting needle is most important parts in Computerized flat knitting machine knitting cycle, is also that use amount is maximum, one of part the most frequently.In barring-on process, adapter ring knitting needle enters between the spring leaf and transfer needle body of transfer needle, and then coverer rollback, keeps coil in the pinhock of adapter ring pin, completes barring-on work.The quality of knitting needle spring leaf directly affects the weave effect of Computerized flat knitting machine, and reduced the service life of knitting needle, has increased production cost.
Summary of the invention
To the object of the invention is in order addressing the above problem, to provide a kind of easy to operate, can test in advance the fatigue test device of knitting needle spring leaf in the fine or not Computerized flat knitting machine of knitting needle.
For this reason, technical scheme of the present invention is: the fatigue test device of knitting needle spring leaf in a kind of Computerized flat knitting machine, is characterized in that: it comprises motor, motor fixing base, fixed cover, bull stick, knitting needle fixed head, fixed block and limited block; Described motor fixing base one side has circular mounting hole, and motor is fixed on motor fixing base, and motor drive shaft is through circular mounting hole; Described fixed cover is circular, is enclosed within on motor drive shaft; Described bull stick is fixed on the circumference of fixed cover, and described bull stick front end has flat head; In the middle of described motor mount, there is a rectangular recess; Described knitting needle fixed head is arranged on motor mount by screw, and described knitting needle fixed head front end is pressed in rectangular recess top; The whole L-shaped structure of described fixed block, fixed block is fixed on motor mount, is positioned at knitting fixed head one side; Described fixed block front end is fixed with a pellet screw; Described limited block is fixed on the port of rectangular recess.
The present invention, by speed and the frequency of the rotation of single-chip microcomputer control motor at regular time and quantity, rotates fixed cover and bull stick on motor drive shaft, the state while simulating knitting needle braiding use spring leaf while making bull stick through knitting needle spring leaf, the performance of test knitting needle spring leaf.Thereby can test in advance the quality of knitting needle, avoid unnecessary loss.When the present invention works, knitting needle is placed in the rectangular recess of motor fixing base, by the pellet screw of knitting needle fixed head and fixed block front end, limits the upper-lower position of knitting needle, by limited block, limit the front and back position of knitting needle; Then regulate the position of bull stick and fixed cover, make bull stick through knitting needle spring leaf; Then open motor, fixed cover and bull stick on motor drive shaft are rotated, state while simulating knitting needle braiding use spring leaf during bull stick process knitting needle spring leaf.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiments of the present invention, be further described in detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is work schematic diagram of the present invention.
The specific embodiment
Referring to accompanying drawing.The present embodiment comprises motor 1, motor fixing base 2, fixed cover 3, bull stick 4, knitting needle fixed head 5, fixed block 6 and limited block 7; Described motor fixing base 2 one sides have circular mounting hole, and motor 1 is fixed on motor fixing base 2, and motor drive shaft is through circular mounting hole; Described fixed cover 3 is circular, is enclosed within on motor drive shaft; Described bull stick 4 is fixed on the circumference of fixed cover 3, and described bull stick 4 front ends have flat head 41; In the middle of described motor mount 2, there is a rectangular recess 21; Described knitting needle fixed head 5 is arranged on motor mount 2 by screw 8, and described knitting needle fixed head 5 front ends are pressed in rectangular recess 21 tops; The whole L-shaped structure of described fixed block 6, fixed block 6 is fixed on motor mount 2, is positioned at knitting fixed head 5 one sides; Described fixed block 6 front ends are fixed with a pellet screw 9; Described limited block 7 is fixed on the port of rectangular recess 21.
During the present embodiment work, knitting needle 10 is placed in the rectangular recess 21 of motor fixing base 2, by the pellet screw 9 of knitting needle fixed head 5 and fixed block 6 front ends, limits the upper-lower position of knitting needle 10, by limited block 7, limit the front and back position of knitting needle 10; Then regulate the position of bull stick 4 and fixed cover 3, make bull stick 4 through knitting needle spring leaf 11; Then open motor 1, fixed cover 3 and bull stick 4 on motor drive shaft are rotated, the state while simulating knitting needle 10 braiding use spring leaf 11 during bull stick 4 process knitting needle spring leaf 11.
