Description

Technical Field

[0001] The invention relates to the technical field of testing equipment, and in particular to a ball durability detection device and a detection method. Background Art

[0002] Balls include sports balls and industrial balls. Different balls have different performance requirements. Basketballs are a common type of sports balls. Performance tests for basketballs include pressure resistance test, wear resistance test, weather resistance test and impact resistance test. The impact resistance test is to analyze the ball's ability to recover after impact and whether it is easy to be damaged. The wear resistance test is to evaluate the degree of wear on the material surface by simulating the friction that the ball will encounter during actual use. Therefore, a special ball durability test device is needed to test the ball performance. However, the existing basketball ball durability test device has certain problems during use:

[0003] 1. When the existing ball durability testing device conducts an impact resistance test on a basketball ball, the device usually lifts the ball to a high place, then allows the ball to fall freely, and observes and records whether the ball has bulges, cracks, and air leaks after the free fall, thereby obtaining the impact resistance of the ball. In the free fall test method, the ball needs to be lifted to a specified height for each test, and the movement of the ball takes a long time, resulting in low test efficiency. When the basketball ball is used for hitting, different surfaces have different impacts on the basketball ball. Therefore, when the basketball ball is subjected to an impact resistance test, different materials of the rebounding plate have different effects on the test results of the impact resistance of the ball. When the existing equipment is tested, no control group is set for different rebounding plates, making it difficult to obtain the impact resistance of the basketball ball for different rebounding plates.

[0004] 2. The existing test of the wear resistance of a basketball ball is to clamp the ball, then use a friction wheel with a grinding wheel to rotate and rub the surface of the ball. After the friction is completed, the ball is taken out, the wear on the surface of the ball is observed, and the wear resistance of the ball is obtained. However, when the ball is clamped, the clamping stability of the existing ball durability detection device is poor, and the friction angle between the friction material and the ball is different, which will cause the contact area and friction force between the ball and the friction material to be different. Therefore, the different friction angles will affect the results of the wear resistance of the ball. However, the existing ball durability detection device is difficult to test the performance of the ball under different friction angles, which reduces the accuracy of the test data.

[0053] Before conducting the wear resistance test of the ball, first record the initial state of the ball, then adjust the angle of the friction test plate 41, turn the hand wheel on the top of the worm 423 to drive the worm 423 to rotate, then drive the worm wheel 424 to rotate and the rotating shaft 422 on it to rotate, and then synchronously drive the rotating head 421 and the friction test plate 41 to rotate, so that the top of the friction test plate 41 rotates toward the inside of the test box 2. The angle adjustment range of the angle adjustment mechanism 4 is 0-30° to prevent the angle from being too large and interfering with the up and down reciprocating motion of the ball. When adjusting within the range, under the same other external conditions, the larger the rotation angle, the larger the contact area between the test ball and the friction test plate 41, and the greater the friction force on the ball. Therefore, by adjusting the angle of the friction test plate 41, the performance of the ball under different contact areas and friction forces can be tested. That is, under a larger angle of friction, the wear degree of the ball surface is smaller and the wear resistance is better. Therefore, the angle of the friction test plate 41 is adjusted. The scale plate 43 is provided with a scale to facilitate observation of the rotation angle of the friction test plate 41.

[0054] Until the friction test plate 41 is adjusted to a specified position, the angle of the friction test plate 41 can be adjusted according to test requirements.

A number of fixing arms 719 are evenly installed on the periphery of the fixing ring 718. A square rod 717 is fixedly connected to the center of the rear side of the reciprocating slider.

[0057] See also Figure 3 , Figure 7 , Figure 8 and Fig. 9 The clamping assembly 76 includes a threaded rod 765 slidably sleeved on the rear end of the square rod 717, and the rear end of the threaded rod 765 is fixedly connected to an arc-shaped pressing block 763 for pressing and tightening the test ball. The front end of the threaded rod 765 is threadedly connected to a rotating plate 766 through a ball nut, and the rear side of the rotating plate 766 is rotatably connected to a pad. A No. 2 spring 764 is sleeved on the outer periphery of the threaded rod 765, and the No. 2 spring 764 is arranged between the arc-shaped pressing block 763 and the pad. Three arc grooves 767 are evenly opened on the rotating plate 766, and a mounting rod 761 is slidably connected inside the arc groove 767.

The guide groove 769 is slidably connected to the limiting slider 72, and the limiting slider 72 is fixedly connected to the No. 2 connecting rod 768.

[0058] During the wear resistance test, the box door 6 is first opened, and the ball to be tested is placed inside the cavity inside the test box 2. At this time, the No. 2 hydraulic cylinder 74 is started, and the output end of the No. 2 hydraulic cylinder 74 drives the No. 2 mounting plate 73 to move backward, and synchronously drives the limit slide rail 77, the upper and lower reciprocating components 71 and the clamping component 76 to move backward, and then synchronously drives the clamping component 76 to extend from the gap between the movable plates 9 into the interior of the test box 2 until the arc-shaped pressure block 763 is pressed onto the ball, and the ball is squeezed onto the friction test plate 41, thereby achieving the primary fixation of the ball. As the squeezing drives the threaded rod 765 to move forward, the No. 2 spring 764 is synchronously compressed, and as the threaded rod 765 moves, the rotating plate 766 is rotated, and then the mounting rod 761 and the clamping plate 762 thereon are synchronously driven to move in the center, and the clamping plate 762 is used to clamp the outer wall of the ball, thereby achieving Secondary fixation, thereby clamping and pressing the ball onto the friction test plate 41, then start the No. 1 drive motor 711, the output end of the No. 1 drive motor 711 drives the rotating disk 712 to rotate, and then synchronously drives the connecting rod 713 and the hinge joint 714 thereon to reciprocate up and down, and then synchronously drives the linkage plate 715 and the arc plate 716 to reciprocate up and down, and at the same time drives the clamping assembly 76 to reciprocate up and down, thereby driving the ball to reciprocate on the friction test plate 41. While the clamping assembly 76 reciprocates up and down, it drives the box door 6 and the movable plate 9 to reciprocate up and down along the mounting groove 10, avoiding interference between the box door 6 and the movable plate 9 and the reciprocating test mechanism 7 during movement. After the test is completed, the output end of the No. 2 hydraulic cylinder 74 contracts to release the clamping of the ball. At this time, take out the ball, observe the wear on the surface of the ball, and compare it with the initial state to obtain the wear resistance of the ball.

[0059] In addition, the present invention also provides a ball durability detection method, which is completed by using the above-mentioned ball durability detection device, and includes the following steps:

[0060] S1: Plate switching: First, the plate switching mechanism 3 is used to switch the rebound plate 344 to be tested. After the switching is completed, the ball to be tested is placed inside the test cavity.

[0061] S2: Impact resistance test: The impact resistance test of the ball is performed using the impact test mechanism 8. The ball is hit by the impact component 81 and then rebounds by the rebound plate 344. Multiple tests are performed and the test data is recorded after the test is completed.

[0062] S3: Angle adjustment: After the impact resistance test is completed, the angle of the friction plate is adjusted by the angle adjustment mechanism 4 to adjust the friction area and friction strength.

[0063] S4: Clamping the ball: After the angle adjustment is completed, the reciprocating test mechanism 7 is used to clamp the ball stably.

[0064] S5: Wear resistance test: After the ball is stably clamped, perform an up and down reciprocating friction test. After the test is completed, observe and record the test results.

[0065] Working principle: During use, the present invention places the sphere into the cavity inside the test box 2. At this time, the plate switching mechanism 3 is used to switch the rebound plate 344. After the switching is completed, the impact test mechanism 8 is used to perform an impact resistance test on the sphere. The tests inside different cavities serve as control groups for each other, which is convenient for synchronously testing the impact resistance of different rebound plates 344, and is beneficial for obtaining the accuracy of the data. The reciprocating test mechanism 7 is used to perform secondary stable clamping on the sphere, which improves the clamping stability of the sphere. Then, the reciprocating test mechanism 7 is used to drive the sphere to reciprocate up and down for friction, which is convenient for testing the wear resistance of the sphere. The angle adjustment mechanism 4 is used to adjust the angle of the friction test plate 41. When other external conditions are the same, the larger the friction angle, the larger the contact area between the sphere and the friction test plate 41, and the greater the friction force, thereby testing the performance data of the sphere under different friction angles. The test results at different angles serve as control groups for each other, which improves the accuracy of the data.
