Description

Technical Field

[0001] The invention relates to the technical field of football detection, in particular to a wear resistance testing device for football. Background Art

[0002] The roller wear tester is one of the commonly used equipment for testing the wear resistance of footballs. It mainly tests the wear resistance of footballs by simulating the rolling and friction conditions of footballs in actual use. During the test, the football is placed in the roller, and the roller rotates at a certain speed to make the football continuously roll in the roller and produce friction with the inner wall of the roller. After a specified time or number of revolutions, the wear of the football surface is observed and measured to evaluate the wear resistance of the football. However, in actual games, footballs not only roll, but also have various complex movement forms and force conditions such as collisions with players' feet and impacts with goals. The existing roller wear tester can only simulate rolling friction and cannot restore the wear conditions of footballs in real scenes, resulting in low reference value of the tested values.

[0003] Furthermore, when the existing roller wear tester is testing the wear resistance of a football, if multiple footballs are tested at the same time, the footballs will pile up and collide with each other in the roller and cannot rub normally. There will be mutual interference between the footballs, so only one football can be tested for wear resistance at a time, which cannot meet the needs of batch testing. Summary of the invention

[0004] In order to overcome the shortcomings of the existing roller wear tester that can only simulate rolling friction but cannot restore the wear condition of the football in the real scene, resulting in low reference value of the tested values ​​and unable to meet the needs of batch testing, the present invention provides a wear resistance performance testing device for football.

[0020] The fixed assembly includes a direct drive motor 101, a movable frame 102 and a fixed ring 103; the direct drive motor 101 is fixedly connected to the lower side of the machine 1; the movable frame 102 is rotatably connected to the machine 1; the output end of the direct drive motor 101 is fixedly connected to the movable frame 102; a plurality of fixed rings 103 are slidably connected to the movable frame 102; each two fixed rings 103 facing each other up and down form a group.

[0021] A plurality of slide rails 10202 in a ring array are fixedly connected to each movable frame 102 ; each fixed ring 103 is composed of an electric slider 10301 and a ring; each electric slider 10301 slides on the corresponding slide rail 10202 .

[0022] It also includes balls 104; each fixing ring 103 is rotatably connected to a plurality of balls 104 in an annular array.

[0023] The impact assembly includes a servo motor 201, a sleeve 202, a spline shaft 203 and an impact hammer 204; the servo motor 201 is fixedly connected to the upper side of the machine cover 2; the sleeve 202 is fixedly connected to the output end of the servo motor 201; the spline shaft 203 is slidably connected to the sleeve 202; and a plurality of impact hammers 204 in a ring array are fixedly connected to the spline shaft 203.

[0024] It also includes a telescopic driving member 205 ; the second telescopic driving member 205 is fixedly connected inside the shaft sleeve 202 , and the second telescopic driving member 205 is an electric push rod; the telescopic end of the second telescopic driving member 205 is fixedly connected to the spline shaft 203 .

[0025] A plurality of protrusions 5001 are provided on the lower side of the friction plate 2 5 .

[0026] When testing the wear resistance of the football, the telescopic end of the telescopic driving member 3 is controlled to extend, driving the machine cover 2 and the friction plate 25 to rise and separate from the machine 1. Then the staff places the football to be tested on the upper side of the friction plate 4, so that the lower side of the football fits to the upper side of the friction plate 4, and the football is located in the two upper and lower opposite fixing rings 103. Then the two upper and lower opposite fixing rings 103 are slid close to each other on the movable frame 102, so that the fixing rings 103 limit and fix the football. After the football is fixed, the telescopic end of the telescopic driving member 3 is controlled to retract, driving the machine cover 2 and the friction plate 25 to descend, so that the friction plate 25 fits to the upper side of the football, and then the direct drive motor 101 is controlled to drive the movable frame 102 to move. The frame 102 and the fixing ring 103 rotate counterclockwise, so that the fixing ring 103 drives the football to roll counterclockwise between the friction plate 1 4 and the friction plate 2 5, and the wear resistance of the football is tested. By rolling the football on the friction plate 1 4 provided with plastic artificial grass and the lower side of the friction plate 2 5 provided with the protrusion 5001, the wear of the football against the plastic artificial grass in the football field and the wear of the football against stones in the sand are simulated, which is conducive to restoring the wear of the football in the real scene and improving the reference degree of the wear resistance value of the tested football. It should be noted that the friction plate 1 4 and the friction plate 2 5 can be replaced with other frosted surfaces, which is conducive to simulating more real scenes for wear resistance testing.

[0027] It is also taken into consideration that, in view of the fact that the difference in air pressure inside the football affects the service life, the present device supports batch testing of footballs of the same material and different air pressures. Therefore, before the test, the staff places the footballs of the same material and different air pressures in the corresponding fixed ring 103. When the football rolls and contacts the friction plate 1 4 and the friction plate 2 5, the footballs of different air pressures are simultaneously contacted with the upper part of the friction plate 1 4 and the lower part of the friction plate 2 5, so that the wear conditions of the footballs of different air pressures during the test are consistent, thereby realizing batch testing of the footballs. After the test is completed, the staff can compare the wear conditions of each football, which is conducive to testing the optimal air pressure range when the football has the strongest wear resistance. Similarly, due to the differences between the materials of the footballs, the present invention can simultaneously perform wear resistance tests on footballs of the same air pressure and different materials under the same wear conditions, which is conducive to testing the wear resistance of footballs of different materials.

[0028] When the fixed ring 103 drives the football to roll counterclockwise between the friction plate 1 4 and the friction plate 2 5, the football rolls between the two fixed rings 103, and the friction between the football and the fixed ring 103 is reduced by the ball 104, thereby reducing the influence of the fixed ring 103 on the wear resistance test of the football. When it is necessary to perform a wear resistance test on footballs of different models and sizes, the distance between the two fixed rings 103 relative to each other can be adjusted so that the fixed ring 103 fits to the outside of the football, which is conducive to performing a wear resistance test on footballs of different models and sizes and enhancing the adaptability of the equipment.

[0029] It is also considered that the football not only rolls during normal use, but is also subjected to the kicking force of the player's feet and the force of colliding with the goal. Therefore, in the process of the movable frame 102 driving the fixed ring 103 and the football to rotate, the servo motor 201 is controlled to drive the sleeve 202 and the spline shaft 203 to rotate counterclockwise along with the movable frame 102, based on the view from top to bottom, so that the spline shaft 203 drives the impact hammer 204 to rotate counterclockwise, and the rotation speed is consistent. When it is necessary to simulate the situation where the football is hit, the servo motor 201 is controlled to drive the sleeve 202 and the spline shaft 203 to rotate counterclockwise instantaneously, based on the view from top to bottom, so that the spline shaft 203 drives the impact hammer 204 to rotate counterclockwise to hit the football, which is conducive to simulating the situation where the football is hit during normal use. The authenticity of the football wear resistance test is enhanced, and the reference value of the detected football wear resistance value is improved. After the impact hammer 204 collides with the football, the servo motor 201 is controlled to drive the shaft sleeve 202 and the spline shaft 203 to decelerate rapidly, so that the spline shaft 203 drives the impact hammer 204 to separate from the football; the impact hammer 204 continues to rotate counterclockwise with the movable frame 102 to avoid interfering with the rotation of the football and prepare for the next impact. When the impact hammer 204 collides with the football, the telescopic end of the telescopic drive member 205 can be controlled to drive the spline shaft 203 to rise and fall, so that the spline shaft 203 drives the impact hammer 204 to rise and fall, which is conducive to colliding with the football from different angles, further enhancing the authenticity of the football wear resistance test and improving the reference value of the detected football wear resistance value.

[0030] Example 2 On the basis of Example 1, Figure 2-Figure 3 and Figure 5-Figure 6 As shown, it also includes an exhaust pipe 401; a plurality of cavities 10201 in a circular array are opened on the movable frame 102; a plurality of exhaust pipes 401 in a circular array are fixedly connected to the movable frame 102; each exhaust pipe 401 is connected to the corresponding cavity 10201; the other end of each exhaust pipe 401 is connected to an external suction device.

[0031] A cleaning comb 402 is also included; a cleaning comb 402 is fixedly connected to the lower side of each cavity 10201 on the movable frame 102; the cleaning comb 402 is made of elastic hard rubber.

[0032] The bottom of each impact hammer 204 is configured to protrude downward, which is beneficial to enhancing the cleaning effect on the friction plate 4 without affecting the normal rotation of the movable frame 102.

[0033] It is also considered that, since the wear resistance test time of the football is relatively long, when the football rolls and rubs between the friction plate 14 and the friction plate 25, the surface debris of the football of poor quality may fall off and fall into the plastic artificial grass in the friction plate 14. When the next batch of footballs are tested, the footballs will contact and rub with the plastic artificial grass on the friction plate 14 and the debris left by the previously tested footballs, which will affect the contact and friction effect between the footballs and the friction plate 14, resulting in a decrease in the reference value of the wear resistance test of the footballs. Therefore, when the movable frame 102 drives the fixed ring 103 and the football to rotate, the control peripheral air The pump uses the suction pipe 401 to suck the cavity 10201, so that the cavity 10201 is attached to the plastic fake grass on the upper side of the friction plate 4 for suction, and the debris and impurities that fall into the cavity are sucked and collected. At the same time, the cleaning comb 402 is driven by the movable frame 102 to move in contact with the plastic fake grass on the upper side of the friction plate 4, which is conducive to combing out the debris and impurities therein for suction and collection, thereby enhancing the cleaning effect of the plastic fake grass on the friction plate 4, preventing the football from contacting and rubbing with the remaining debris, avoiding affecting the contact and friction effect between the football and the friction plate 4, and ensuring the reference value of the football wear resistance test value.

[0034] When the vacuum pipe 401 and the cleaning comb 402 clean the plastic artificial grass on the upper side of the friction plate 4, the telescopic driving member 205 is controlled to drive the spline shaft 203 and the impact hammer 204 to rise and fall repeatedly, so that the impact hammer 204 collides with the upper side of the friction plate 4, thereby causing the elastic material on the upper part of the friction plate 4 to vibrate, which is conducive to vibrating and loosening the remaining debris and impurities therein, making it easier for the vacuum pipe 401 and the cleaning comb 402 to clean the impurities.
