Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of badminton fatigue strength test, in particular to a test device integrating badminton fatigue strength test and feather piece elasticity test. BACKGROUND

[0002] The structure of a badminton is shown in FIG. 1, which includes a head 1, a plurality of feather pieces 2 evenly arranged along the circumferential direction of the head 1, each of the feather pieces 2 including a feather stem 3 and a plurality of feathers distributed on one end of the feather stem 3, and the other end of the feather stem 3 of each of the feather pieces 2 being fixedly installed on the head 1. Figure 1

[0003] The badminton produced in the workshop is of different quality, and the quality of the badminton depends on the resistance of the feather pieces to beating. After a batch of badminton is produced in the workshop, a part of the badminton is sampled and subjected to fatigue strength test. The specific test method is as follows: a worker fixes the head 1 of the badminton by a clamp, and then beats the feather pieces 2 around the badminton by a beating head reciprocatingly. After a certain number of beats, the damage degree of the feather pieces 2 is observed. If the damage degree of the feather pieces 2 is small, the fatigue strength of the badminton is determined to be qualified. If the damage degree of the feather pieces 2 is large, the fatigue strength of the badminton is determined to be unqualified, thereby completing the fatigue strength test of one badminton. The above operation is repeated to test the fatigue strength of the sampled badminton.

[0004] However, this test method can test the fatigue strength of the badminton, but still has the following technical defects in technology:

[0005] I. The worker needs to manually hold the beating head to reciprocatingly beat the badminton to complete the fatigue strength test of the badminton. Since the number of badminton to be tested is large, manual test undoubtedly increases the working strength of the worker, and also increases the test time of the fatigue strength of the badminton, thereby reducing the test efficiency of the fatigue strength of the badminton.

[0006] II. This test method can only test the fatigue strength of the badminton, but cannot test the elasticity of a single and independent feather piece 2. The process requires to test the elasticity of a single feather piece 2 to provide parameters for the research and development of the badminton, so the test range is limited.

[0007] Therefore, there is an urgent need for a test device integrating badminton fatigue strength test and feather piece elasticity test, which can test the elasticity of the feather piece and improve the test efficiency of the fatigue strength of the badminton. SUMMARY

[0037] The elasticity test is performed on a single and independent hair piece 2, and the specific operation steps are as follows:

[0038] S1, the worker loosens the locking screws 18 between the pressing block 17 and the fixing block 14, so that the semicircular pad 16 of the pressing block 17 is separated from the fixing block 14;

[0039] S2, the worker takes out a to-be-tested feather piece 2, and sends the feather stem 3 of the feather piece 2 into the area surrounded by the semicircular pad 16 between the pressing block 17 and the fixed block 14; then the locking screw 18 is tightened again, under the threaded connection force, the feather stem 3 of the feather piece 2 is fixed between the pressing block 17 and the semicircular pad 16, so that the fixture fixing of the to-be-tested feather piece 2 is realized, as shown in Figures 9-10 At this time, the upper end of the feather piece 2 is just opposite the beating block 11;

[0040] S3, the worker controls the servo motor 20 to start, the servo motor 20 drives the driving pulley 21 to rotate, the driving pulley 21 drives the driven pulley 22 to rotate through the belt 23, the belt 23 drives the mounting seat 7 to move to the right, the mounting seat 7 drives the pressure sensor 8, the mounting plate 9, the transmission rod 10 and the beating block 11 to move to the right synchronously, when the beating block 11 presses the upper end of the feather piece 2, the reaction force of the feather piece 2 is sequentially transmitted to the pressure sensor 8 through the beating block 11, the transmission rod 10 and the mounting plate 9, and finally to the pressure sensor 8, the pressure sensor 8 transmits the pressure value to the controller, at this time, the display screen of the controller displays the elasticity of the feather piece 2, so that the elasticity test of the feather piece 2 is realized, and parameters are provided for the research and development of badminton;

[0041] The specific operation steps for testing the fatigue strength of the badminton are as follows:

[0042] S4, the worker unscrews the locking screw between the pressing block 17 and the fixed block 14, then takes away the semicircular pad 16 in the fixed block 14, and takes away the pressing block 17;

[0043] S5, the worker takes out a to-be-tested badminton as shown in Figure 1 , inserts the head 1 of the badminton into the first arc-shaped groove 15 of the fixed block 14; then turns over the removed pressing block 17, when the pressing block 17 is turned over, the worker fixes the pressing block 17 on the fixed block 14 through the locking screw 18, at this time, the head 1 of the badminton is fixed between the first arc-shaped groove 15 and the second arc-shaped groove 19 of the pressing block 17, so that the fixture fixing of the to-be-tested badminton is realized, as shown in Figures 11-12 ;

[0044] S6, the worker controls the stepping motor to start, the stepping motor drives the rotating table 13 to rotate, the rotating table 13 drives the fixed block 14 and the pressing block 17 to rotate synchronously, and further drives the badminton to rotate synchronously; at the same time, the servo motor 20 is controlled to rotate in the forward and reverse directions, the servo motor 20 drives the driving pulley 21 to rotate in the forward and reverse directions, so that the beating block 11 beats each feather piece 2 of the badminton in the forward and reverse directions, and at the same time, the pressure value fed back by the pressure sensor 8 is displayed on the display screen of the controller at each time of impact;

[0045] If the number of times that the hitting block 11 hits the setting number, the pressure value fed back by the pressure sensor 8 is still in the setting value range, it is determined that the fatigue strength of the badminton is qualified; if the pressure value fed back by the pressure sensor 8 is significantly lower than the setting value, it means that the badminton has been damaged by hitting, and then it is determined that the fatigue strength of the badminton is unqualified product, thereby completing the fatigue strength test of a badminton;

[0046] S7, the worker repeats the operation of steps S4-S6, that is, the fatigue strength test of multiple badminton can be continuously performed.

[0047] Among them, from steps S5-S6, the test device can automatically test the fatigue strength of the badminton through the linkage cooperation of the servo motor 20, the hitting block 11 and the stepping motor, without the worker holding the hitting head to hit the badminton back and forth, so as to complete the test of the fatigue strength of the badminton, thereby greatly reducing the working strength of the worker; in addition, the badminton selected for sampling can be tested in a short time, thereby greatly improving the test efficiency of the fatigue strength of the badminton.
