Abstract

The invention discloses the fatigue test device of knitting needle spring leaf in a kind of Computerized flat knitting machine, comprise motor, motor fixing base, fixed cover, bull stick, knitting needle fixed head, fixed block and limited block; Described motor fixing base 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, and cover on the motor; Described bull stick is fixed on fixed cover circumferentially; 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 above rectangular recess; The overall L-shaped structure of described fixed block, fixed block is fixed on motor mount; Described limited block is fixed on the port of rectangular recess.The present invention passes through speed and the frequency of the rotation of single-chip microcomputer control motor at regular time and quantity, makes bull stick use the state of spring leaf through the braiding of knitting needle spring leaf simulation knitting needle, the performance of test knitting needle spring leaf.

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 of transfer needle and transfer needle body, then coverer rollback, is kept by 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 the service life of knitting needle is reduced, and adds production cost.
Summary of the invention
The object of the invention is to solve the problem, providing a kind of easy to operate, the fatigue test device of knitting needle spring leaf in the Computerized flat knitting machine of the quality of knitting needle can be tested in advance.
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 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, and cover on the motor; Described bull stick is fixed on fixed cover circumferentially, and described bull stick front end has flat head; In the middle of described motor fixing base, there is a rectangular recess; Described knitting needle fixed head is arranged on motor fixing base by screw, and described knitting needle fixed head front end is pressed in above rectangular recess; The overall L-shaped structure of described fixed block, fixed block is fixed on motor fixing base, is positioned at knitting needle fixed head 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 passes through speed and the frequency of the rotation of single-chip microcomputer control motor at regular time and quantity, makes the fixed cover on motor drive shaft and bar rotation, makes bull stick use the state of spring leaf through the braiding of knitting needle spring leaf simulation knitting needle, the performance of test knitting needle spring leaf.Thus the quality of knitting needle can be tested in advance, avoid unnecessary loss.When the present invention works, knitting needle is placed in the rectangular recess of motor fixing base, is limited the upper-lower position of knitting needle by the pellet screw of knitting needle fixed head and fixed block front end, limited the front and back position of knitting needle by limited block; Then regulate the position of bull stick and fixed cover, make bull stick through knitting needle spring leaf; Then open motor, make the fixed cover on motor drive shaft and bar rotation, bull stick uses spring leaf state through the braiding of knitting needle spring leaf simulation knitting needle.
Accompanying drawing explanation
Be further described in detail below in conjunction with accompanying drawing and embodiments of the present invention.
Fig. 1 is structural representation of the present invention.
Fig. 2 is operating diagram of the present invention.
Detailed description of the invention
See 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 side has 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, and cover on the motor; Described bull stick 4 is fixed on fixed cover 3 circumferentially, and described bull stick 4 front end has flat head 41; In the middle of described motor fixing base 2, there is a rectangular recess 21; Described knitting needle fixed head 5 is arranged on motor fixing base 2 by screw 8, and described knitting needle fixed head 5 front end is pressed in above rectangular recess 21; The overall L-shaped structure of described fixed block 6, fixed block 6 is fixed on motor fixing base 2, is positioned at knitting needle fixed head 5 side; Described fixed block 6 front end is 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, is limited the upper-lower position of knitting needle 10 by the pellet screw 9 of knitting needle fixed head 5 and fixed block 6 front end, limited the front and back position of knitting needle 10 by limited block 7; 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, the fixed cover 3 on motor drive shaft and bull stick 4 are rotated, state during knitting needle 10 braiding use spring leaf 11 simulated by bull stick 4 when knitting needle spring leaf 11.
