Abstract
A kind of multi-functional test desk that is used for the sewing machine performance test, part of detecting is made up of buncher, torque rotary speed sensor, tested head.Buncher can directly drive tested head, also can be by gap bridge axle, the torque rotary speed sensor on same axis, drag tested head, buncher, gap bridge axle again, torque rotary speed sensor is located on the adjustable for height hoistable platform, and tested machine is fixed on the testing stand by base used specially.This test board integrates and tests the speed, surveys noise, surveys torque, power scale and carry out the simulated condition durability test, can be used for the optimization of sewing machine quality examination, product evaluation and product design.
Description
The present invention is a kind of equipment that is used for the sewing machine performance test.
The test of sewing machine performance is the important means of the examination of sewing machine product quality, new product performance evaluation and product development optimal design.The testing apparatus of sewing machine performance in the past can only be done the single performance test to a certain machine, does not have to adapt to the multifunctional integrated test platform of various machines.
The present invention will provide a kind of the testing the speed, survey noise, survey rotating torque of sewing machine head, power scale of collecting, and carry out function such as examination of following life-span of simulated condition, can adapt to the multi-functional test desk of various machines.
China's sewing machine industry standard has been stipulated the method for test sewing machine head starting torque.Method regulation, tested sewing machine head main shaft must with the shaft of the instrument of test moment of torsion in same axial location, the shaft of tester speed is 25/min.The data of measuring like this have very big limitation, are difficult to reflect the dynamic perfromance of tested sewing machine, also give the universalization of testing apparatus, and multifunction is brought very big difficulty.
The present invention is design like this.Entire equipment is made up of part of detecting and control section, and part of detecting is by adjustable speed motor, and torque rotary speed sensor and tested head are formed.Varying-speed motor can have two approach to drag tested head running, and the direct belt wheel that drives tested sewing machine head of belt wheel that approach is a buncher makes its running; Or by another approach, promptly buncher drives torque rotary speed sensor by being not limited to be located at the gap bridge axle on the same axis, drags tested sewing machine head running on the table top again.Wherein tested sewing machine head is fixed on the testing stand by the base used specially of this machine; Buncher, the axle of passing a bridge, torque rotary speed sensor all is arranged on the hoistable platform that highly can regulate, the lifting of platform can be regulated the tension force of driving belt, to guarantee arriving the height of base when inconsistent when the belt pulley center of tested machine, torque rotary speed sensor or motor drag the tension force basically identical of the belt of tested machine.
Now the invention will be further described in conjunction with the embodiments.
Fig. 1 is the front elevation of multi-functional test desk for sewing machine;
Fig. 2 is multi-functional test desk for sewing machine hoistable platform planimetric position figure;
Fig. 3 is the nylon shaft coupling of the input/output terminal of torque rotary speed sensor.
The multi-functional test desk for sewing machine that proposes according to the present invention is made up of control section and part of detecting.Control section can carry out speed governing to motor, and measurement result is shown, prints.Analog condition is set, and test period is carried out record, and data are carried out computing, to satisfy the needs of various tests.Part of detecting is by buncher, and torque rotary speed sensor and tested head are formed.Also has 1, one hoistable platform 2 of a frame in addition.Buncher 3, the axle 4 of passing a bridge, torque rotary speed sensor 5 are arranged on the hoistable platform, main shaft between the three all is not limited on same straight line, tested sewing machine head 6 is fixed on the testing stand 8 by base used specially 7, base used specially 7 is custom-designed according to the structure of different machines, by the ⊥ shape groove of testing stand, can fix easily.
Buncher can drag tested head running by two approach, article one, be the direct belt wheel 6a that drives tested head of belt wheel 3a of buncher, another is the belt wheel 3b drive idler 4a of buncher, and drive the input belt wheel 5a of torque rotary speed sensor by another idler 4b, 5b is connected to the sensor input end by input end nylon shaft coupling, drive output terminal belt wheel 5d by output terminal nylon shaft coupling 5c again, drive the belt wheel 6a of tested sewing machine head at last by output terminal belt wheel 5d.Two approach are only got one when test, can not use simultaneously.Nylon shaft coupling 5b, the 5c at sensor two ends can improve the stability that transmission is coupled.
Because does not wait to the height of head bottom surface at the belt pulley center of each machine,, at this moment can regulate the required tensioning degree of belt during with the maintenance transmission so will cause belt tension inconsistent by the height of regulating hoistable platform 2.The lifting of platform can be passed through multiple modes such as spiral, rack-and-pinion, worm and gear, pneumatic, hydraulic pressure, and present embodiment adopts hydraulic lifting system.
The buncher of present embodiment is selected the electromagnetic clutch buncher of the GFTB type eddy current type semi-permanent structure of speed governing good braking performance and good for use, instantaneous starting when testing to satisfy, the requirement of instantaneous braking.Adopt ZJ type torque rotary speed sensor.
The multi-functional test desk that utilizes the present invention to propose can be tested the various performances of sewing machine.For example:
Survey machine speed: adopt the direct or indirect kind of drive, drive, tested head is rotated, adopt this moment the instrument that generally tests the speed to test the speed by buncher.
Survey noise: adopt the direct kind of drive,, utilize sound meter can record noise under the different rotating speeds to tested head input different rotating speeds.The noise of this test board is compared and can be ignored with the sewing machine noise.
Survey rotating torque: adopt the indirect drive mode, insert torque rotary speed sensor.When tested head turned round, the torque arm of sensor was reversed, and the phase differential of magnetic test coil detecting signal changes, and according to the size of phase change, just can measure torque value.This test board can be measured the dynamic process of rotating torque from low speed to high speed.
Power scale: utilize formula W=(nN)/974 can calculate, this test board can calculate performance number automatically.
Carry out the examination of simulated condition life-span: adopt directly or indirectly and rotate; periodic duty mode by normal operative condition " sewing-shutdown-sewing-shutdown " is moved; control section can be set sewing machine time, stop time, and can set its continuous examination time, then shut down.Therefore can under the situation of unsupervised, do the 500h durability test.
